Adherence to antiretroviral therapy and factors associated with non-adherence: a cohort study at two referral services in Brazil.

This cohort study evaluated non-adherence to antiretrovirals at referral services in Pernambuco, Brazil, 2016/2017, through self-report. A generalized mixed-effects model for binary outcomewas used. We assessed 542 participants with an adherence rate of 85.50%. A greater chance of non-adherence was associated with:a low/moderate level of nicotine dependence (OR = 2.79, p = 0.00, IC = 1.44-5.41); ≥7 tablets/day (OR = 6.14, p = 0.00, IC = 3.42-11.02); LPV/r (OR = 1.49, p = 0.6, IC = 0.98-2.26), ddI (OR = 3.34, p = 0.03, IC = 1.12-9.97), ABC (OR = 4.02, p = 0.05, IC = 1.01-16.03), RAL (OR = 2.49, p = 0.01, IC = 1.32-4.70) and DTG (OR = 4.65, p = 0.01, IC = 1.42-15.16); 6-10 year seropositive diagnosis (OR = 2.17, p = 0.01, IC = 1.20-3.92) and symptoms of depression (OR = 1.55, p = 0.03, IC = 1.03-2.33). Protective factors for non-adherence weres: ≥50 years (OR = 0.67, p = 0.06, IC = 0.45-1.01), secondary/higher education (OR = 0.48, p = 0.00, IC = 0.34-0.70), embarrassment at health service (OR = 0.49, p = 0.04, IC = 0.24-0.97), good understanding of antiretrovirals (OR = 0.62, p = 0.03, IC = 0.40-0.96), adverse event (OR = 0.74, p = 0,06, IC = 0.54-1.01), use of TDF (OR = 0.62, p = 0.01, IC = 0.43-0.90), NVP (OR = 0.41, p = 0.05, IC = 0.71-1.00) and EFZ (OR = 0.48, p = 0.01, IC = 0.29-0.80) and good knowledge of HIV/AIDS/ART. (OR = 0.67, p = 0.07, IC = 0.43-1.04). Variables with stronger association were those linked to ART. Systematic use of self-report adherence is recommended for priority groups.

Evaluating outcome domains assessing caregivers of individuals with mental illness: a review.

In this article, we describe the properties and consider the outcome dimensions of a collection of self-administered questionnaires that assess caregivers of offspring with mental illness. To this end, we searched the MEDLINE, Web of Science, and PsycINFO databases, as well as reference lists of studies published between 1980 and 2012. We reviewed 43 instruments, and found multiple outcome domains, associated with either objective burden or subjective burden, or both. A number of tools captured additional negative aspects of caregiving (e.g., strain, stress, and worrying) as well as positive aspects (e.g., personal growth, strength, support, rewards, and satisfaction), supplemented by measures assessing caregivers' perceptions and attitudes toward their offspring with SMI (e.g., insight, stigma, and efficacy). This current review of existing measures and their specific domains contributes to a more comprehensive understanding of the caregiving experience and allows both clinicians and researchers to select the most appropriate measurement tools for their purposes.

Psychometric Properties of the Personality Inventory for DSM-5 faceted Brief Form in a Brazilian Community Sample.

OBJECTIVE: The aim of the present study was to verify the psychometric qualities of the PID-5-FBF in a community sample of Brazilian adults. The internal consistency of the facets and the internal structure of the dimensions were checked. In addition, we verified the correlations between the PID-5-FBF facets and domains with a five-factor model measure. METHODS: The sample of this study consists of the 774 Brazilian adults aged 18 to 73 years (mean 28.9±11.58) who answered the PID-5-FBF and BFI-2S. RESULTS: The alpha values were adequate. The internal structure was similar to the PID-5 original form. All the factors and dimensions of the PID-5-FBF have a negative association with agreeableness, while, on the other hand, all correlations with neuroticism were positive. Neuroticism was the factor with the highest correlation with the PID-5-FBF, and openness was the one with the lowest number of correlations. CONCLUSIONS: This research contributes to adding evidence of validity to the PID-5-FBF in the Brazilian community sample. Our results are important because it is the first study with the PID-FBF in a Brazilian sample.

Is there consensus on child violence exposure measures? A study of six recommended instruments.

Background: International research has established that children and adolescents are at high risk for being exposed to violence. A systematic review published in 2023 recommended six child and adolescent self-report violence against children (VAC) measures, based on their psychometric properties, in a systematic COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) review. However, the degree of overlap and heterogeneity was not part of the analysis.Objective: To compare the six measures with respect to item overlap and differences concerning specification of exposure dimensions.Method: A content analysis of the original 174 items resulted in a reduction to 38 unique items. These items were organized visually in a co-occurrence circle using an adapted version of Fried's R code. Furthermore, a pairwise comparison of event lists was performed using the Jaccard index.Results: There was a modest overlap among the six measures. Only one item was present in all six measures, only two items were present in four measures, and 78% of the items were present in just one or two measures. The overall overlap between the six measures was 25%.Conclusions: The lack of overlap among measures reflects a heterogeneity of definitions and purposes. It also impedes progress in research, as comparisons between various studies are difficult to make in a valid and reliable way. The lack of consensus also delays efficient political initiatives, because solid, consensual knowledge about the prevalence of VAC does not exist.

Violence against children (VAC) is a high political and professional priority. A recent systematic review recommended six self-report measures based on their psychometric qualities.The VAC items were very diverse. A content analysis reduced the original 174 items to 38 unique items. A Jaccard index showed an overlap of 25%.The lack of consensus in definitions and applied measures impedes progress in research and delays important political, prophylactic initiatives.

Inventory of Interpersonal Problems-Personality Disorders: adaptation to Brazil and test of a bifactor model.

OBJECTIVE: The Inventory of Interpersonal Problems-Personality Disorders (IIP-PD-47) has a controversial factor structure, as some studies have provided support for 5 correlated factors, and others have suggested the existence of a general second-order dimension. One approach of data modelling that reconciles multidimensionality and the existence of a general factor is the bifactor analysis. We used unrestricted exploratory-confirmatory bifactor modelling to validate the Brazilian version of the IIP-PD-47. METHODS: The sample consisted of 1,091 subjects aged 18-64 years who answered the IIP-PD-47 and a collateral measure of pathological traits, the Dimensional Clinical Personality Inventory 2 (IDCP-2). RESULTS: After testing many candidate models, our data were best represented by a bifactor model with one general factor and five specific uncorrelated factors. Nevertheless, a closer inspection of the discriminant validity of each IIP-PD-47 factor revealed strong support for the general factor and a factor capturing aggressive behaviours, but less support for the additional four specific factors. CONCLUSIONS: The theoretical and practical implications of these findings are discussed, and some recommendations are offered about the need for controlling response styles when assessing PD traits via self-report inventories. Our findings indicate that the Brazilian version of IIP-PD has promising psychometric properties.

Objetivo: El Inventario de Problemas Interpersonales-Trastornos de la Personalidad (IIP-PD-47) tiene una estructura factorial controvertida, ya que algunos estudios han apoyado 5 factores correlacionados y otros han sen˜ alado la existencia de una dimensión general de segundo orden. Un enfoque del modelado de datos que concilia la multidimensionalidad y la existencia de un factor general es el análisis de bifactores. Para validar la versión brasileña del IIP-PD-47, se utilizó un modelo bifactorial confirmatorio exploratorio sin restricciones. Métodos: La muestra incluyó a 1.091 sujetos de 18 a 64 anos que respondieron al IIP-PD-47 y una medida colateral de rasgos patológicos, el Inventario de Personalidad Clínica Dimensional 2 (IDCP-2). Resultados: Después de probar muchos modelos candidatos, nuestros datos se representaron mejor mediante un modelo bifactorial con 1 factor general y 5 factores específicos no correlacionados. Sin embargo, una inspección más cercana de la validez discriminante de cada factor IIP-PD-47 reveló un fuerte respaldo del factor general y un factor que capta comportamientos agresivos, pero menos respaldo a los 4 factores específicos adicionales. Conclusiones: Se discuten las implicaciones teóricas y prácticas de estos hallazgos y se ofrecen algunas recomendaciones sobre la necesidad de controlar los estilos de respuesta al evaluar los rasgos de la EP a través de inventarios de autoaplicados. Nuestros hallazgos indican que la versión brasileña de IIP-PD tiene propiedades psicométricas prometedoras.

Métodos: Se realizó un estudio transversal en una muestra de 345 participantes mayores de 18 años, estudiantes de una universidad en Lima, Perú y que completaron el instrumento de recogida de datos. Los dos métodos usados para la medición de FVD fueron el cuestionario de Hayes que define un caso positivo para FVD con un puntaje igual o mayor a 20; y el cuestionario CVS-Q de Seguí, que define como positivo para FVD con un puntaje mayor a 6. Se estimó el coeficiente kappa de Cohen con su intervalo de confianza al 95% para medir la concordancia global y por estratos. Resultados: El cuestionario de Hayes identificó a 167 (48,4%) participantes con un diagnostico presuntivo de FVD, el cuestionario de Seguí identificó a 247 (71,6%) estudiantes. En el análisis de concordancia, el coeficiente Kappa de Cohen fue 0,45 (IC95%; 0,37 - 0,53) (p < 0,01) en el análisis global, considerado como moderado. Conclusiones: El grado de concordancia entre ambos métodos fue moderado, el instrumento de Seguí identificó una mayor proporción de estudiantes universitarios con FVD.

ABSTRACT Objective: To obtain the frequency of digital visual fatigue (DVF) using two questionnaires among students of a private university in Lima, Peru; to estimate the degree of agreement between both methods. Methods: A cross-sectional study was conducted in a sample of 345 participants over 18 years old, students of a university in Lima, Peru and who completed the data collection instrument. The two methods used for the measurement of DVF were the Hayes questionnaire, which defines a positive case for DVF with a score equal to or greater than 20; and the Seguí CVS-Q questionnaire, which defines a positive case for DVF with a score greater than 6. The Cohen's kappa coefficient with its 95% confidence interval was estimated to measure the overall agreement and by strata. Results: The Hayes questionnaire identified 167 (48.4%) participants with a presumptive diagnosis of DVF, the Seguí questionnaire identified 247 (71.6%) students. In the concordance analysis, Cohen's Kappa coefficient was 0.45 (95%CI; 0.37 - 0.53) (p < 0.01) in the overall analysis, considered moderate. Conclusion: The degree of concordance between both methods was moderate, the Seguí instrument identified a higher proportion of university students with DVF.

Normative Values for the Spanish Version of the Voice Symptom Scale (VoiSS)

Objective: The aim of this study was to establish normative values for the Voice Symptom Scale (VoiSS) in the Spanish community population (without voice problems), using a sample from a large area of southeastern Spain. Method: The sample consisted of 115 adults from ages 16 to 87, 60 of whom were women and 55 were men. Participants included the family members of patients who attended the Otorhinolaryngology (ENT) and Speech Therapy Clinic at a referral hospital in the region of Murcia, Spain, and some of the clinic's staff. All the participants reported never having suffered from any voice disorder before. Results: The normative values obtained in this study for the VoiSS were 14.61 (SD=8.18) for the total score, 7.57 (SD = 5.42) for the Impairment subscale, 1.04 (SD = 1.65) for the Emotional subscale, and 5.99 (SD = 3.61) for the Physical subscale. The percentile values were also obtained for the VoiSS scale and for its three subscales. Conclusions: This study presents normative values for the VoiSS scale that have not previously been obtained in Spain. These values can be used as a reference to detect possible voice disorders.

Estos valores pueden utilizarse como referencia para detectar posibles trastornos de voz.

La interseccionalidad como herramienta teórico-analítica para estudiar las desigualdades en salud en las Américas / Intersectionality as a theoretical-analytical tool to study health inequalities in the Americas / A interseccionalidade como ferramenta teórico-analítica para estudo das desigualdades em saúde nas Américas

RESUMEN Objetivo. Analizar las desigualdades en la salud autopercibida entre grupos de población situados en las intersecciones de identidad de género, grupo étnico y nivel de educación en países de las Américas, clasificados según su nivel de ingreso. Métodos. Se utilizaron datos en panel de la Encuesta Mundial de Valores en el período comprendido entre los años 1990 y 2022. La muestra de este estudio incluyó 58 790 personas entre 16 y 65 años, provenientes de 14 países del continente americano. La variable dependiente fue la mala salud autopercibida, las variables independientes fueron el género, el nivel de educación y el grupo étnico. Para el análisis interseccional intercategórico se creó una variable multicategórica de 12 estratos. Se realizó un análisis de heterogeneidad individual y precisión diagnóstica mediante cinco modelos de regresión logística ajustados por edad y ola de encuesta. Resultados. Se observó un claro y persistente gradiente interseccional para la mala salud autopercibida en todas las desagregaciones de países por su ingreso. Comparados con la categoría más aventajada (hombres de etnia mayoritaria y educación superior), los demás grupos incrementaron el riesgo de mala salud, con el mayor riesgo en las mujeres de etnia minoritaria o pueblos indígenas con nivel de educación inferior a secundaria (tres a cuatro veces mayor). Además, las mujeres tuvieron mayor riesgo de mala salud respecto a los hombres en cada uno de los pares de estratos interseccionales. Conclusiones. El análisis interseccional demostró la persistencia de un gradiente social de la mala salud autopercibida en el continente americano.

ABSTRACT Objective. Analyze inequalities in self-perceived health among population groups located at the intersections of gender identity, ethnicity, and education level in countries of the Americas, classified by income level. Methods. Panel data from the World Values Survey were used for the period 1990-2022. The study sample included 58 790 people between 16 and 65 years of age from 14 countries in the Americas. The dependent variable was poor self-perceived health, and the independent variables were gender, education level, and ethnicity. A multi-categorical variable with 12 strata was created for the intercategorical intersectionality analysis. An analysis of individual heterogeneity and diagnostic accuracy was performed using five logistic regression models, adjusted by age and by survey wave. Results. A clear and persistent intersectional gradient for poor self-perceived health was observed in all country disaggregations by income. Compared to the category with the most advantage (men of majority ethnicity and higher education), the other groups had increased risk of poor health, with the highest risk among women of minority ethnicity and in Indigenous peoples with less than secondary education (three to four times higher). In addition, women had a higher risk of poor health than men in each pair of intersectional strata. Conclusions. The intersectional analysis demonstrated a persistent social gradient of self-perceived ill health in the Americas.

RESUMO Objetivo. Analisar desigualdades na autopercepção de saúde entre grupos populacionais localizados nas interseções de identidade de gênero, etnia e nível de escolaridade em países das Américas, classificados pelo nível de renda. Métodos. Foram usados dados em painel da Pesquisa Mundial de Valores referentes ao período de 1990 a 2022. A amostra deste estudo incluiu 58 790 pessoas com idades entre 16 e 65 anos de 14 países das Américas. A variável dependente foi a autopercepção de problemas de saúde, e as variáveis independentes foram gênero, nível de escolaridade e etnia. Para a análise interseccional intercategórica, foi criada uma variável multicategórica de 12 estratos. Foi realizada uma análise da heterogeneidade individual e da precisão do diagnóstico usando cinco modelos de regressão logística ajustados por idade e onda de pesquisa. Resultados. Observou-se um gradiente interseccional claro e persistente para a autopercepção de problemas de saúde em todas as desagregações de países por renda. Em comparação com a categoria mais favorecida (homens de etnia majoritária e com ensino superior), todos os outros grupos apresentaram maior risco de problemas de saúde, com o maior risco para mulheres de etnias minoritárias ou povos indígenas com nível de escolaridade inferior ao ensino médio (três a quatro vezes maior). Além disso, as mulheres tinham um risco maior de problemas de saúde do que os homens em cada um dos pares de estratos interseccionais. Conclusões. A análise interseccional demonstrou a persistência de um gradiente social na autopercepção de problemas de saúde nas Américas.

Autorreporte de salud y su relación con la obesidad en adultos de México y Argentina, 2018 / Self-rated health and its relation with obesity among adults in Mexico and Argentina, 2018

INTRODUCCIÓN: Existe evidencia de que el autorreporte de salud está relacionado con la obesidad, aunque la asociación estaría mediada por las enfermedades o condiciones que afectan la salud o por el sexo o la edad de la persona. En países con elevadas prevalencias de obesidad en adultos, como México o Argentina, es fundamental estudiar la relación entre el autorreporte de salud y la obesidad para comprender los factores que afectan la autoevaluación. El objetivo fue determinar esa relación en adultos de 50 y más años de México y Argentina. MÉTODOS: Este estudio transversal analizó la salud autoevaluada en forma global respecto de la definición de obesidad según el índice de masa corporal. Los datos provinieron de la ronda 2018 del Estudio Nacional de Salud y Envejecimiento en México y de la cuarta Encuesta Nacional de Factores de Riesgo 2018 de Argentina. Se construyeron modelos de regresión logit ordinal con probabilidades proporcionales parciales para determinar la relación entre el autorreporte y la obesidad, ajustando por variables socioeconómicas y de salud. RESULTADOS: Se asoció menor probabilidad de un autorreporte de salud buena ante la presencia de obesidad, pero esto solo fue significativo en mujeres. DISCUSIÓN: Es necesario explorar las diferencias entre mujeres y hombres que atañen a la relación entre el autorreporte de salud y la obesidad, así como la percepción o valoración cultural o social de la obesidad diferenciada por sexo en adultos de México y Argentina.

Construindo escalas de autorrelato: o que fazer? / Developing self-report scales: what to do? / Construcción de escalas de autoinforme: ¿qué hacer?

Escalas de autorrelato são comuns no cotidiano de pesquisadores, porém detalhes, que às vezes parecem de pouca importância, acabam sendo desconsiderados. Autorrelato são caracterizados pela pessoa de interesse ser a própria fonte de informação do pesquisador, assim a forma em que as possibilidades de resposta são apresentadas é de suma importância. Os formatos de resposta mais comuns são tipo Likert e as escolhas forçadas que vem ganhando popularidade nos últimos anos. Neste artigo são apresentados os elementos necessários que devem ser observados quando se constrói ou se escolhe escalas que possuam esses dois formatos de resposta. São discutidos também a quantidade de itens ou blocos necessários, as opções de resposta, polaridade dos itens, sistema de correção, bem como ao final são indicadas boas práticas na construção de itens para ambos os formatos. Dessa forma, pretende-se contribuir para a Psicologia, em especial a área de construção de instrumentos de autorrelato.(AU)

Self-report scales are common in the daily lives of researchers, however, details, which sometimes seem of little importance, can end up being disregarded. Self-reports are characterized by the person of interest being the researcher's own source of information, therefore the way in which the response possibilities are presented is of paramount importance. The most common response formats are Likert type and forced choice, which have been gaining popularity in recent years. This article presents the elements that must be observed when developing or choosing scales that have these two response formats. Also discussed are the number of items or blocks needed, the answer options, item polarity, the correction system, and good practices in the construction of items for both formats. The intention is to contribute to Psychology, especially the area of construction of self-report instruments.(AU)

Association between the level of indifference to dental treatment and habits of oral hygiene in adults / Asociación entre el nivel de indiferencia al tratamiento dental y los hábitos de higiene bucal

Introduction: Inadequate oral hygiene habits such as lack of tooth brushing, use of irrigators, fluoridated toothpastes, and dental floss, as well as the importance of worrying about going to the dentist in the event of any problem in the oral cavity and the continuity of treatment are factors that could increase the risk in patients. Objetive: To determine the association between the level of indifference to dental treatment and the oral hygiene habits of those surveyed adults. Material and Methods: An observational, analytical and cross-sectional study. The level of indifference to dental treatment was evaluated using a translated virtual questionnaire and subsequently internally validated (Cronbach's alpha: 0.91). There were a total of 249 participants, 150 males and 99 females, with a mean age of 30.69 years. For the association of the qualitative variables and the report of the crude and adjusted odds' ratio (OR), a logistic regression was used. We worked with a level of statistical significance of p<0.05 and a confidence interval of 95%. Results: A high level of indifference to dental treatment was obtained in 57.83% of the respondents. Likewise, a statistically significant association was found between indifference to dental treatment and education (p = 0.012). Regarding oral hygiene habits, a statistically significant association was found with flossing (OR = 2.22; 95% CI: 1.10-4.46) (p = 0.025) and brushing before sleeping (OR = 5.26; 95%: 2.26-12-22) (p<0.001). Conclusion: There is a statistically significant association between the level of indifference to dental treatment with oral hygiene habits, flossing and brushing before sleeping. It is advisable to carry out activities in the communities to promote oral health care to reduce levels of indifference to dental treatment.

Introducción: Los inadecuados hábitos de higiene bucal como la falta de cepillado dental, uso de irrigadores, pastas dentales fluoradas e hilo dental, así como la importancia de preocuparse por acudir al odontólogo ante cualquier problema en la cavidad oral y la continuidad del tratamiento son factores que podrían agravar el riesgo en los pacientes. Objetivo: Determinar la asociación entre el nivel de indiferencia al tratamiento dental y los hábitos de higiene bucal de los encuestados en adultos en edades comprendidas entre los 18 a 45 años de la urbanización Buenos Aires de Villa en Chorrillos, Perú. Material y Métodos: Se realizó un estudio observacional, analítico y transversal. El nivel de indiferencia al tratamiento dental fue evaluado mediante un cuestionario virtual traducido y posteriormente validado internamente (alpha de Cronbach: 0.91). Se tuvo un total de 249 participantes, entre ellos 150 hombres y 99 mujeres con una media edad de 30,69 años. Para la asociación de las variables cualitativas y el reporte de las Odds Ratio (OR) crudas y ajustadas, se empleó una regresión logística. Se trabajó con un nivel de significancia estadística de p<0.05 y un intervalo de confianza del 95%. Resultados: Se obtuvo un alto nivel de indiferencia al tratamiento dental en el 57.83% de los encuestados. Asimismo, se encontró una asociación estadísticamente significativa de la indiferencia al tratamiento dental con la educación (p= 0.012). Respecto a los hábitos de higiene bucal, se encontró asociación estadísticamente significativa con uso de hilo dental (OR=2.22; IC del 95%: 1.10-4.46) (p=0.025) y el cepillado antes de dormir (OR=5.26; IC del 95%: 2.26-12-22) (p<0.001). Conclusión: Se concluyó que existe una asociación estadísticamente significativa entre el nivel de indiferencia al tratamiento dental con los hábitos de higiene bucal uso de hilo dental y cepillado antes de dormir. Se aconseja realizar actividades en las comunidades para promover el cuidado de la salud bucal con la finalidad de reducir los niveles de indiferencia al tratamiento dental.

Fatores associados à adesão a terapia imunossupressora em indivíduos transplantados renais / Factors associated with adherence to immunosuppressive therapy in renal transplant recipients / Factores asociados a la adherencia a la terapia inmunosupresora en receptores de trasplante renal

Objetivo: Analisar os fatores associados à adesão a terapia imunossupressora em indivíduos transplantados renais. Métodos: Trata-se de estudo de corte transversal, com indivíduos transplantados renais em acompanhamento ambulatorial, na cidade do Recife, Nordeste do Brasil. Utilizou-se a Assessment of Adherence with Immunosuppressive Medication Scale para avaliar a adesão aos imunossupressores. Resultados: Em 147 transplantados renais, foi observada uma prevalência de mulheres (51,70%) com baixa escolaridade e baixo nível socioeconômico (60,54%). A amostra foi composta, em sua maioria, por receptores de enxerto renal proveniente de doador cadáver (50,34%), com tempo de espera para o transplante de até 48 meses (62,59%). A taxa de adesão dos participantes foi de 56,42%, e esteve associada ao tempo médio pós-transplante (p=0,033), com maior índice naqueles com menos de 5 anos de transplante renal. Os fatores associados a não adesão foram atrasos e esquecimentos. Conclusão: Considerando a necessidade de ampliar a taxa de adesão, é fundamental considerar o tempo de transplante renal no planejamento das ações. Além disso, é preciso utilizar estratégias que auxiliem na manutenção da tomada dos imunossupressores conforme prescrição médica a fim de contribuir para a manutenção do enxerto renal. (AU)

Objective: To analyze the factors associated with adherence to immunosuppressive therapy in kidney transplant patients. Methods: This is a cross-sectional study, with kidney transplant patients undergoing outpatient follow-up, in the city of Recife, Northeast Brazil. The Assessment of Adherence with Immunosuppressive Medication Scale was used to assess adherence to immunosuppressants. Results: In 147 kidney transplant recipients, there was a prevalence of women (51,70%), with low education and low socioeconomic status (60,54%). The sample consisted, mostly, of kidney graft recipients from cadaver donors (50,34%), with a waiting time for transplantation of up to 48 months (62,59%). The adherence rate of the participants was 56.42%, and was associated with the average post-transplant time (p = 0.033), with a higher rate in those with less than 5 years of kidney transplantation. The factors associated with non-adherence were delays and forgetfulness. Conclusion: Considering the need to increase the adherence rate, it is essential to consider the time of kidney transplantation when planning actions. In addition, it is necessary to use strategies that assist in maintaining the intake of immunosuppressants according to medical prescription in order to contribute to the maintenance of the renal graft.

Objetivo: Analizar los factores asociados a la adherencia a la terapia inmunosupresora en receptores de trasplante renal. Métodos: Se trata de un estudio transversal con pacientes con trasplante renal en seguimiento ambulatorio, en la ciudad de Recife, noreste de Brasil. Se utilizó la Assessment of Adherence with Immunosuppressive Medication Scale para evaluar la adherencia a los inmunosupresores. Resultados: En 147 receptores de trasplante renal, hubo una prevalencia de mujeres (51,70%), con bajo nivel educativo y nivel socioeconómico bajo (60,54%). La muestra estuvo compuesta, mayoritariamente, por receptores de injerto renal de donante cadáver (50,34%), con un tiempo de espera para el trasplante de hasta 48 meses (62,59%). La tasa de adherencia de los participantes fue del 56,42% y se asoció con el tiempo medio pos trasplante (p = 0,033), con una tasa mayor en aquellos con menos de 5 años de trasplante renal. Los factores asociados a la no adherencia fueron los retrasos y el olvido. Conclusión: Considerando la necesidad de incrementar la tasa de adherencia, es fundamental considerar el momento del trasplante renal a la hora de planificar acciones. Además, es necesario utilizar estrategias que ayuden a mantener la ingesta de inmunosupresores según prescripción médica para contribuir al mantenimiento del injerto renal. (AU)

RESUMEN Objetivo. Identificar la prevalencia del autoinforme de síntomas, del acceso al testeo y del diagnóstico de la enfermedad por el coronavirus del 2019 (COVID-19, por su sigla en inglés), así como su asociación con determinantes sociales de la salud (DSS). Métodos. Estudio transversal con una muestra de 11 728 hombres y 12 612 mujeres mayores de 17 años, con base en la Encuesta Nacional de Hogares 2020. Las variables dependientes fueron el autoinforme de síntomas, de acceso al testeo y de una prueba positiva para COVID-19. Las variables independientes fueron la edad, el nivel de educación, la zona de residencia y geográfica, la etnia, el tipo de hogar, el ingreso per cápita, la actividad y el seguro de salud. Se calcularon prevalencias, asociaciones bivariadas y modelos de regresión logística binomial (razón de momios [OR] e intervalo de confianza del 95% [IC95%]). Resultados. Del total de personas incluidas, 16% notificó síntomas, 10% un testeo y 4,2% una prueba positiva para COVID-19. Existieron desigualdades en la notificación de síntomas de COVID-19, con una mayor probabilidad en las mujeres cuyos ingresos habían disminuido (OR: 1,7; IC95%: 1,2-2,4) y las personas desempleadas (OR: 1,2; IC95%: 1,1-1,4 para los hombres y OR:1,3; IC: 1,5-1,5 para las mujeres). En cambio, con respecto al acceso a las pruebas diagnósticas, la mayor probabilidad se observó en personas con educación superior (OR: 2.4; IC95%: 1,9-2,9 para los hombres y OR: 2,7; IC95%: 2,2-3,4 para las mujeres), cuyos ingresos se mantuvieron (OR: 1,5; IC95%: 1,3-1,9 para los hombres y OR: 1,7; IC95%: 1,4-2,0 para las mujeres) y del cuartil de ingreso per cápita en el hogar más alto (OR: 2,0; IC95%:1,6-2,5 para los hombres y OR: 1,6; IC95%: 1,3-2,0 para las mujeres). La probabilidad de notificar síntomas, realizarse una prueba y el diagnóstico para COVID-19 aumentó con la edad, para las personas que contaban con seguro de salud y residentes en los llanos; por otra parte, disminuyó para residentes de zonas rurales. Conclusiones. Existen desigualdades en el acceso al testeo y en la notificación de síntomas de la COVID-19.

ABSTRACT Objective. To identify the prevalence of self-reporting of symptoms and access to testing and diagnosis of coronavirus-19 disease (COVID-19), as well as its association with social determinants of health (SDH). Methods. Cross-sectional study with a sample of 11 728 men and 12 612 women over the age of 17, based on the National Household Survey 2020. The dependent variables were the self-reporting of symptoms, access to testing, and a positive COVID-19 test. The independent variables were age, educational level, area of residence and geographic area, ethnicity, type of household, income per capita, occupation, and health insurance. Prevalences, bivariate associations, and binomial logistical regression models (odds ratio (OR), and 95% confidence interval (CI95%) were calculated. Results. Of the total individuals included, 16% reported symptoms, 10% a test, and 4.2% a positive COVID-19 test. Inequalities were observed in the reporting of COVID—19 symptoms, with a higher probability in women whose income had fallen (OR: 1.7; CI95%: 1.2-2.4) and unemployed persons (OR: 1.2; CI95%: 1.1-1.4 for men and OR: 1.3; CI95%: 1.5-1.5 for women). In contrast, with respect to access to diagnostic tests, the highest probability was observed in people with higher education (OR: 2.4; CI95%: 1.9-2.9 for men and OR: 2.7; CI95%: 2.2-3.4 for women), whose income was maintained (OR: 1.5; CI95%: 1.3-1.9 for men and OR: 1.7; CI95%: 1.4-2.0 for women) and those in the highest quartile of per capita household income (OR: 2.0; CI95%: 1.6-2.5 for men and OR: 1.6; CI95%: 1.3-2.0 for women). The probability of reporting symptoms and getting tested, and being diagnosed with COVID-19 increased with age for people with health insurance and those living in the llanos region; however, it decreased for residents of rural areas. Conclusions. There are inequalities in access to testing and the reporting of COVID-19 symptoms.

Foram calculados prevalência, associações bivariadas e modelos de regressão logística binomial (odds ratio [OR] e intervalo de confiança de 95% [IC95%]). Resultados. Do total de pessoas incluídas, 16% relataram sintomas; 10%, realização de teste; e 4,2%, um teste positivo para COVID-19. Houve desigualdades no relato de sintomas de COVID-19, com maior probabilidade em mulheres cuja renda havia diminuído (OR: 1,7; IC95%: 1,2-2,4) e que estavam desempregadas (OR: 1,2; IC95%: 1,1 -1,4 para homens e OR: 1,3; IC95%: 1,5-1,5 para mulheres). Em contrapartida, quanto ao acesso a exames diagnósticos, a maior probabilidade foi observada em pessoas com nível superior (OR: 2,4; IC95%: 1,9-2,9 para homens e OR: 2,7; IC95%: 2,2-3,4 para mulheres) cuja renda foi mantida (OR: 1,5; IC95%: 1,3-1,9 para homens e OR: 1,7; IC95%: 1,4- 2,0 para mulheres) e pertencentes ao maior quartil de renda domiciliar per capita (OR: 2,0; IC95%: 1,6-2,5 para homens e OR: 1,6; IC95%: 1,3-2,0 para mulheres). A probabilidade de relatar sintomas, fazer o teste e ser diagnosticado com COVID-19 aumentou com a idade e foi maior nos casos de pessoas que têm plano de saúde e nos de moradores da região dos llanos. Por outro lado, foi menor nos casos de moradores de áreas rurais. Conclusões. Existem desigualdades no acesso a testes e na notificação de sintomas de COVID-19.

[Analysis of the reliability and validity of three self-report questionnaires to assess physical activity among Spanish adolescents]. / Análisis de fiabilidad y validez de tres cuestionarios de autoinforme para valorar la actividad física realizada por adolescentes españoles.

OBJECTIVE: To analyse the reliability and validity of the Weekly Activity Checklist (WAC), the One Week Recall (OWR), and the Godin-Shephard Leisure Time Exercise Questionnaire (GLTEQ) in Spanish adolescents. METHODS: A total of 78 adolescents wore a pedometer for one week, filled out the questionnaires at the end of this period and underwent a test to estimate their maximal oxygen consumption (VO2max). The reliability of the questionnaires was determined by means of a factor analysis. Convergent validity was obtained by comparing the questionnaires' scores against the amount of physical activity quantified by the pedometer and the VO2max reported. RESULTS: The questionnaires showed a weak internal consistency (WAC: α=0.59-0.78; OWR: α=0.53-0.73; GLTEQ: α=0.60). Moderate statistically significant correlations were found between the pedometer and the WAC (r=0.69; p <0.01) and the OWR (r=0.42; p <0.01), while a low statistically significant correlation was found for the GLTEQ (r=0.36; p=0.01). The estimated VO2max showed a low level of association with the WAC results (r=0.30; p <0.05), and the OWR results (r=0.29; p <0.05). When classifying the participants as active or inactive, the level of agreement with the pedometer was moderate for the WAC (k=0.46) and the OWR (r=0.44), and slight for the GLTEQ (r=0.20). CONCLUSION: Of the three questionnaires analysed, the WAC showed the best psychometric performance as it was the only one with respectable convergent validity, while sharing low reliability with the OWR and the GLTEQ.

Prevalence of corrected arterial hypertension based on the self-reported prevalence estimated by the Brazilian National Health Survey / Prevalência de hipertensão arterial corrigida com base na prevalência autorreferida estimada pela Pesquisa Nacional de Saúde / Prevalencia de la hipertensión arterial corregida, basada en la prevalencia autoinformada, estimada por la Encuesta Nacional de Salud Brasileña

The objective was to correct the self-reported prevalence of systemic arterial hypertension (SAH) obtained from the Brazilian National Health Survey (PNS 2013). SAH prevalence estimates were corrected by means of sensitivity/specificity of information. Sensitivity and specificity values from a similar study (same self-report question, age range and gold standard) were used to this end. A sensitivity analysis was also performed, by using the upper and lower limits of confidence intervals as sensitivity and specificity parameters. The corrected prevalence of SAH for Brazil as a whole was 14.5% (self-reported: 22.1%). Women presented a higher rate of self-reported SAH but, after correction, men were found to have a higher prevalence. Among younger women (18-39 age range), the self-reported prevalence was 6.2%, a value that, after correction, dropped to 0.28%. There was not much difference between self-reported and corrected SAH among the elderly (51.1% vs. 49.2%). For certain groups the corrected results were greatly different from the self-reported prevalence, what may severely impact public health policy strategies.

O estudo teve como objetivo corrigir a prevalência autorreferida de hipertensão arterial sistêmica (HAS) obtida pela Pesquisa Nacional de Saúde (PNS 2013). As estimativas de prevalência de HAS foram corrigidas pelos dados de sensibilidade/especificidade. Foram utilizados os valores de sensibilidade e especificidade de um estudo semelhante (mesma pergunta autorreferida, faixa etária e padrão de ouro). Foi utilizada também a análise de sensibilidade, com os limites superiores e inferiores dos intervalos de confiança enquanto parâmetros de sensibilidade e especificidade. A prevalência corrigida de HAS para o Brasil como um todo foi de 14,5% (autorreferida: 22,1%). As mulheres apresentaram uma prevalência mais alta de HAS autorreferida, mas depois da correção, os homens mostraram uma prevalência mais alta. Entre as mulheres mais jovens (18-39 anos), a prevalência autorreferida foi de 6,2%, caindo para 0,28% depois da correção. Nos idosos, não houve muita diferença entre a HAS autorreferida e a corrigida (51,1% vs. 49,2%). Para determinados grupos, os resultados corrigidos foram muito diferentes da prevalência autorreferida, o que pode ter um impacto relevante nas estratégias de saúde pública.

El objetivo fue corregir la prevalencia autoinformada de hipertensión arterial sistémica (HAS), obtenida de la Encuesta Nacional de Salud Brasileña (PNS 2013). Las estimaciones de prevalencia HAS se corrigieron mediante información de sensibilidad/especificidad. Los valores de sensibilidad y especificidad de un estudio similar (la misma pregunta autoinformada, rango de edad y estándar de excelencia) se usaron hasta el final. También se realizó un análisis de sensibilidad, usando los límites superiores e inferiores de los intervalos de confianza como parámetros de sensibilidad y especificidad. La prevalencia corregida de HAS para Brasil como un todo fue 14,5% (autoinformada: 22,1%). Las mujeres presentaron una tasa más alta de HAS autoinformada pero, tras la corrección, los hombres fueron quienes tuvieron una prevalencia más alta. Entre mujeres más jóvenes (con un rango de edad entre 18-39), la prevalencia autoinformada fue 6,2%, un valor que, tras la corrección, cayó al 0,28%. No hubo mucha diferencia entre la HAS autoinformada y la corregida entre ancianos (51,1% vs. 49,2%). Para ciertos grupos los resultados corregidos fueron considerablemente diferentes respecto a la prevalencia autoinformada, lo que quizás tiene un impacto severo en las estrategias de las políticas públicas de salud.

Barreiras à Carreira e Saúde Mental de Estudantes de Pós-graduação / Career-related Barriers and Mental Health of Graduate Students / Barreras en la Carrera y Salud Mental de Estudiantes de Posgrado

Barreiras à carreira são circunstâncias relativas ao indivíduo ou ao contexto que dificultam o avanço na carreira. Este estudo teve por objetivo identificar as barreiras de carreira percebidas por pós-graduandos brasileiros. Os 1619 participantes responderam a um survey on-line com instrumentos psicométricos para caracterização da amostra e uma questão aberta sobre barreiras à carreira enfrentadas. Realizaram-se análises estatísticas descritivas de média e frequência dos dados quantitativos e análises de redes semânticas dos dados linguísticos. Os principais resultados indicaram níveis moderados de depressão, ansiedade e estresse e que a “falta de tempo” e “o orientador acadêmico” são as barreiras mais recorrentes nos autorrelatos. Conclui-se que a orientação profissional e de carreira se faz relevante para auxiliar acadêmicos em formação a alcançarem sucesso e saúde mental em suas carreiras.

Career-related barriers are circumstances related to the individual or the context that hinder career advancement. This study sought to identify career barriers perceived by Brazilian graduate students. The 1619 participants answered an online survey with psychometric instruments and one open-ended question regarding the main career barriers faced. Descriptive statistical analyzes included mean, and frequency of the sample characterization data and semantic network analyzes of the linguistic data on the career-related barriers. The main results indicate moderate levels of depression, anxiety, and stress and that “lack of time” and “the academic advisor” are the most recurrent barriers in self-reports. We conclude that professional and career guidance is relevant to assisting academics in training to achieve career success and mental health.

Las barreras profesionales son circunstancias relacionadas con el individuo o el contexto que obstaculizan el avance profesional. Este estudio tuvo como objetivo identificar las barreras profesionales percibidas por estudiantes de posgrado brasileños. Los 1619 participantes respondieron una encuesta online con instrumentos psicométricos y una pregunta abierta sobre las principales barreras profesionales enfrentadas. Se realizaron análisis estadísticos descriptivos de los datos cuantitativos y análisis de redes semánticas de los lingüísticos. Los principales resultados indicaron niveles moderados de depresión, ansiedad y estrés, y que la “falta de tiempo” y “el asesor” son las barreras más frecuentes en los relatos. Se concluye que la orientación profesional y de carrera puede ayudar a los académicos a lograr el éxito en la carrera y a estar saludables mentalmente.

Cuestionario de bruxismo autoinformado. Estudio piloto en el noreste de México / Self-reported bruxism questionnaire. A pilot study in northeastern Mexico

Resumen El diagnóstico adecuado del bruxismo incluye el análisis y la correlación de signos y síntomas con diferentes métodos de diagnóstico, siendo esencial la interpretación y evaluación de los síntomas que reporta el paciente. El presente es un trabajo inicial sobre las propiedades psicométricas del cuestionario de bruxismo autoinformado (CBA). Participaron 100 personas (34 hombres y 66 mujeres) del noreste de México, la muestra se dividió en dos grupos, uno con diagnóstico clínico y autoinforme de bruxismo (N = 50) y otro sin bruxismo. Se evaluó la confiablidad por consistencia interna, la estructura factorial y la validez convergente entre la escala de estrés percibido PSS-14 y el CBA. Los resultados muestran consistencia interna entre los 11 ítems (α = .88). El análisis factorial confirmatorio para un solo factor presentó índices estadísticos de bondad de ajuste adecuados (χ2/gl = 1.461; GFI = .916; AGFI = .857, CFI = .967, RMSEA = .068). La correlación entre las escalas PSS-14 y CBA fue positiva (r = .27; p = .001), y entre la escala de estrés percibido y las subescalas bruxismo de sueño r = .20 (p = .039) y bruxismo de vigilia r = .29 (p = .002), La correlación entre las subescalas BS y BV fue r = .71 (p = .001), Los resultados del CBA muestran alta confiabilidad, consistencia interna y correlación inter-ítems apropiada, y respaldan la validez convergente del cuestionario. Asimismo, contribuyen a mejorar los estándares de calidad al evaluar los datos subjetivos aportados por personas con bruxismo y se considera de interés continuar con el análisis del CBA, evaluando su comportamiento en otras poblaciones.

Abstract Bruxism is defined as a repetitive jaw-muscle activity, characterized by grinding or clenching the teeth, and /or by bracing or thrusting of the mandible, which has different circadian manifestations, either during sleep (sleep bruxism) or when wakefulness (awake bruxism). For an appropriate clinical diagnosis of bruxism different techniques have been proposed; the most common technique is the usage of a self-reported questionnaire combined with a professional evaluation. While the first is a questionnaire in which the patient expresses their symptoms, the second depends on the presence of observed signs associated according to an evaluator, including tooth wear as well as identify symptoms associated to this jaw-muscle activity, to confirm a clinical diagnosis, there must be a correlation between the self-report questionnaire and clinical diagnosis. Therefore, there is no quantifiable measure that may help to evaluate, from a patient's perspective, the signs and symptoms that belongs to his/her muscle and mandibular activity while assessing both its proportion and measure. To strengthen the self-report technique as a reliable procedure for assessing the information expressed by patient with bruxism, this initial study reports the reliability and validity proprieties of the self-report bruxism questionnaire (CBA). The present study was conducted in Mexico and includes one hundred participants. Fifty percent of them presented a clinical diagnosis of bruxism (n = 50), the other half (control group) do not. In both groups the perceived stress scale (PSS) and the self-reported bruxism questionnaires (CBA) were equally completed on a self-administered way. Both a high internal consistency (α = .884) was found on the eleven items and a corrected item-total correlation ranged from .43 to .78, reflects an adequate reliability. The exploratory factor analysis was used to group the CBA variables; the extraction was made using a main component with Varimax rotation method. The sample adequacy coefficients, the Kaiser Meyer-Olkin (KMO = .826) and Bartlett's Sphericity test (χ2 = 579.866, p = .000) were assessed and expressed an appropriate intercorrelation between items. The factor analysis showed a bifactorial: the latent variables explained one factor of 47.8 % (eigenvalue = 5.26) variance and another of 11.5 % (eigenvalue = 1.27), thus its cumulative variance of this model was 59.36 %. Due to amount of explained variance and the difference between the eigenvalues of this initial solution we considered to prove a unidimensional model. A one solution factor scale was feasible, with factor weights greater than .52 on all items. This single-factor structure was verified in a confirmatory factor analysis, which presented significant values and suitable goodness of fit indexes (χ2/df = 1.461; GFI = .916; AGFI = .857, CFI = .967, RMSEA = .068). Also, a convergent analysis was performed proving a positive (r = .27; p = .001) correlation between the PSS-14 and CBA scales, the correlation with the subscales of self-reported awake bruxism, SAB was positive (r = .299, p = .002). Regarding self-reported sleep bruxism, SAB the correlation was also positive (r = .207, p = .039). The correlation between the subscales was both positive and strong (r = .713, p = .001). Based on the results obtained, we can conclude that, there are a positive, significant, and adequate correlation between PSS-14 scale and the scale of self-reported bruxism, as though as in the sub-scales SAB and SSB. These results suggested that the one factor solution of the CBA has high reliability, internal consistency, and an appropriate inter-item correlation; also, it supports the convergent validity of the questionnaire. Due to the possible contributions of the CBA to the improvement of the quality standards of the evaluation of subjective data provided by people with bruxism, it is suggested to continue with the analysis of the scale in future studies with other populations.
