[Predictor variables of contraceptive method use in young people: A systematic review]. / Variables predictoras del uso de los métodos anticonceptivos en jóvenes: una revisión sistemática.

OBJECTIVE: To analyse predictor variables of contraceptive method use in young people. DESIGN: Systematic review. DATA SOURCES: PubMed, CINAHL, Scopus, Cuiden Plus, LILACS and IME databases were consulted. STUDY SELECTION: An assessment of the quality of studies was carried out by two researchers in parallel. As a result, a total of 5 primary research studies were selected. DATA EXTRACTION: Information was extracted on the selected study population, contraceptive method studied and predictor variables identified. RESULTS: Seven predictor variables were identified that specifically explain the use of the male condom, contraceptive pill or emergency contraceptive pill. The most relevant variables were the level of knowledge and attitudes towards contraceptive use, therefore high knowledge and positive attitudes increase the likelihood of contraceptive use. Another notable finding was the presence of a formative bias with women having higher knowledge of hormonal contraceptive options and more positive attitudes. CONCLUSION: Future training programs should be oriented towards assessing behavioral changes through the development of positive attitudes towards contraceptive use by gaining knowledge of contraceptive options.

Clinical characteristics and severity of COVID-19 among Mexican adults.

INTRODUCTION: Obesity, diabetes, hypertension and age have been pointed at as factors that influence on the progression of COVID-19; however, evidence for other conditions is inconclusive. OBJECTIVE: To identify which clinical characteristics are related to COVID-19 severity and to determine whether age acts a modifier of the relationship between cardio-metabolic comorbidities (CMC) and COVID-19 progression. METHOD: Data on ≥ 20-year-old confirmed cases (n = 159,017) were analyzed. Hospitalization, development of pneumonia, intubation requirement, intensive care unit admission and death were the dependent variables in Poisson regression models estimation, whereas the interaction between age and different CMCs were the independent variables. RESULTS: Having CMCs, as well as other comorbidities, was directly related to COVID-19 progression, whereas chronic obstructive pulmonary disease was only related to an increase in the risk of dying. The risk for COVID-19 severity was lower as age was more advanced. Asthma and smoking were not risk factors for the progression of COVID-19. CONCLUSION: In the Mexican population, the risk of COVID-19 progression associated with comorbidities was higher in young adults.

INTRODUCCIÓN: Se ha señalado que factores como obesidad, diabetes, hipertensión y edad influyen en la progresión de COVID-19; sin embargo, la evidencia para otras condiciones no es concluyente. OBJETIVO: Identificar qué antecedentes clínicos están relacionados con la gravedad de COVID-19 y si la edad funge como un modificador de efecto de la relación entre comorbilidades cardiometabólicas (CCM) y progresión de COVID-19. MÉTODO: Se analizaron los datos de casos confirmados ≥ 20 años (n = 155 017). La hospitalización, el desarrollo de neumonía, el requerimiento de intubación, el ingreso a la unidad de cuidados intensivos y la muerte constituyeron las variables dependientes en la estimación de modelos de regresión de Poisson y la interacción entre edad y CCM, las independientes. RESULTADOS: Tener CCM, así como otras comorbilidades, se relacionó directamente con la progresión de COVID-19. El riesgo de gravedad de COVID-19 asociado a las CCM fue menor conforme la edad era mayor. El asma y el tabaquismo no fueron factores de riesgo para la progresión de COVID-19. CONCLUSIÓN: En la población mexicana, el riesgo de progresión de COVID-19 asociada a comorbilidades fue mayor en los adultos jóvenes.

A multicentric Spanish study on the characteristics and survival of gastric adenocarcinoma under the age of 60.

INTRODUCTION: In Europe, gastric adenocarcinoma (GADC) is commonly regarded as a disease of the elderly. This study aims to assess the proportion, characteristics, and survival of patients diagnosed with GADC under the age of 60. MATERIALS AND METHODS: This is a retrospective, multicentric, and analytical study conducted at four tertiary Spanish hospitals. All patients diagnosed with GADC between 2008 and 2015 were included. Demographic, clinical, endoscopic, histologic, and survival data were retrieved. A multivariate analysis was performed to compare GADC in young (age≤60 years) and elderly patients. RESULTS: A total of 1374 patients with GADC were included. The mean age was 74 years (SD:11.1); 62.2% were males. There were 177 patients under the age of 60 (12.9%, 95% CI: 11.2-14.8%). GADC was frequently encountered as a metastatic disease in both young and elderly patients (Stage IV: 45.7% and 41%, respectively). In the multivariate analysis, alcohol abuse, ASA functional status I-II, diffuse subtype, neoadjuvant, and palliative therapy were independently associated (P<0.05) with age ≤60 years. No differences were found in 2-year survival (GADC ≤60: 39% vs. 35%, P=0.45). Curative-intent surgery, TNM stage I-II, body mass index<30kg/m2, and better functional status at diagnosis were independent predictors of survival in GADC under the age of 60. CONCLUSIONS: One out of eight cases of GADC were diagnosed under the age of 60. Metastatic disease was frequent at diagnosis and overall survival was poor regardless of age. Factors associated with localized disease correlated with improved survival in younger patients. Our results underline the need for early diagnosis strategies in our country.

[Sexist attitudes and recognition of abuse in young couples]. / Actitudes sexistas y reconocimiento del maltrato en parejas jóvenes.

AIM: To explore the association between gender-role attitudes and the recognition of abuse among adolescents and young adults during dating relationships. DESIGN: Cross-correlation study. LOCATION: 57 schools of secondary education, vocational education and university in five provinces of Spain (Huelva, Seville, A Coruña, Pontevedra and Asturias). PARTICIPANTS: 4,337 students aged between 15 and 26 years (40.6% males and 59.4% female) who had a dating relationship that lasted more than a month. MAIN MEASUREMENTS: The Gender Role Attitudes Scale was used, which consists of 20 indicators of egalitarian or sexism attitudes at the family, social and occupational level. The students also reported whether they suffered from recognized abuse (RA), unperceived abuse (UPA), or not abused (NA). RESULTS: In the whole sample, 68.6% declared themselves NA, 26.4% were under a situation of UPA, and 5.0% were RA. The RA group was more frequent among the females (6.3%), ≥18 years (6.4%) and university students (6.9%). UPA was more common in males (30.2%). The most sexist attitudes were found in the occupational dimension and especially in men and adolescents (15-17 years). Less sexist attitudes were associated with a lower probability of experiencing UPA (odds ratio=.71; P-trend<.001). CONCLUSIONS: Sexism seems to hinder the recognition of abuse. Achieving gender equity in adolescence and youth is imperative. Public health efforts should focus on men, as they constitute the group with more sexist attitudes and with higher prevalence of UPA.

Social capital as a moderator of the relationship between violent community environment and psychological distress.

OBJECTIVE: To evaluate the modifying effect of social capital on the relationship between living in violent communities and the presence of psychological distress in adolescents and youth in Mexico. METHOD: The analysis of the Social Cohesion Survey for the Prevention of Violence and Crime (ECOPRED, by its acronym in Spanish) was conducted. The analytic sample consisted of 39,639 participants aged 12 to 29 years. Community violence and social capital were measured at the census tract level using the average answers of a household's head sample. These environmental variables were independent of the experiences of the participants. Social capital variables included structural (social ties, recreational participation, collaborative participation, and social cohesion), and cognitive (trust in neighbors) dimensions. Multilevel structural equation models were used. RESULTS: Recreational participation, collaborative participation, and social cohesion modified the relationship between community environments and psychological distress. In females who lived in places with less recreational participation or less social cohesion, the higher the social disorder, the higher the psychological distress. A similar relationship between vandalism and psychological distress was identified, but only in males who lived in places with less collaborative participation, and in females with less social cohesion. CONCLUSIONS: Our results suggest that dimensions of the structural social capital (organization and interest in the community and its members) were the ones that had the buffering effect of the exposure to disordered community environments on psychological distress.

Juvenile idiopathic arthritis in the young adult. Methodology, objectives, and initial data from the JUVENSER registry.

OBJECTIVES: To describe the methodology, objectives, and initial data of the registry of young adult patients diagnosed with Juvenile Idiopathic Arthritis (JIA), JUVENSER. The main objective of the project is to know the sociodemographic and clinical characteristics, and disease activity of patients with JIA reaching the transition to adulthood. MATERIAL AND METHOD: Longitudinal, prospective, multicentre study, including patients between 16 and 25 years old, with a diagnosis of JIA in any of its categories. The main objective is to determine the characteristics and activity of JIA in the young adult. It includes sociodemographic variables, clinical variables, disease activity and joint damage rates, data on the use of health resources, and treatments used. The total duration of the project will be 3 years. A cohort of 534 young adult patients was obtained. CONCLUSIONS: The JUVENSER registry will constitute a cohort of young adults with JIA, which will allow the evaluation of the clinical characteristics and response to treatment of patients with disease onset in childhood, moving to adult clinics.

Dating violence and its relationship with anxiety, depression, and stress in young Andalusian university students.

AIM: To analyze the prevalence of dating violence (DV) and its relationship with states of depression, anxiety, and stress in young Andalusian university students. METHOD: Cross-sectional descriptive quantitative study in 8 public universities in Andalusia. Data collection was carried out from September to November 2020 through a self-administered questionnaire that included sociodemographic variables and variables related to dating violence, depression, anxiety, and stress. For the analysis of the data, descriptive and nonparametric tests were performed through the U Mann-Whitney and Spearman Rho for the relationship between variables. RESULTS: Thousand ninety-one young university students from Andalusia participated. The most prevalent DV was psychological, including behaviors related to cyberbullying, control-surveillance and psychoemotional (68.42-42.90%), followed by sexual (16.68-3.57%) and finally physical (5.60-1.92%). Statistically significant differences were shown according to sex and DV, where girls scored higher in being victims of behaviors related to cyberbullying, control-surveillance and sexual, and boys in perpetrating psycho-emotional, physical and sexual violence. All types of DV showed significant and positive correlations with depression, anxiety, and stress, except physical DV perpetrated with stress. CONCLUSIONS: The high prevalence of DV and its relationship with mental health show the importance of conducting research on this line in the educational field, since it is a space that guarantees egalitarian relationships and promotes health.

Alcohol, age at first sexual intercourse and number of sexual partners in young Mexican women.

AIM: To identify the relationship between use of alcohol, number of sexual partners and age of sexual initiation. METHOD: Descriptive-correlational study. A random sample of 319 young women (age 18-25) from Nuevo Laredo, Mexico was recruited. A sociodemographic data sheet and the AUDIT questionnaire were used. Non-parametric Spearman's rank correlation coefficient and Kruskal-Wallis H test were selected. RESULTS: On average the participants were 20.70 years old (±2.1), had 1.86 sexual partners (±1.27), started drinking alcohol at the age of 16.82 (±1.79), and their first sexual intercourse was at the age of 17.38 (±1.65). There was a decrease in the age of onset of alcohol use (H=16.646, p<.001) and the age at first sexual intercourse (H=26.749, p<.001) on the lower their current age. The overall AUDIT score negatively correlated with the age of the participants on their first sexual intercourse (rs=-.168, p<.001) and positively correlated with the number of sexual partners (rs=.243, p<.001). The aforementioned correlations were more intense among the younger participants (18- and 19-year olds; p<.01). CONCLUSIONS: There was an association between higher use of alcohol, early age of sexual initiation and number of sexual partners. Nursing professionals may address such variables simultaneously through preventive strategies directed specifically at young women.

Strength of association of classical vascular risk factors in young patients with ischaemic stroke: a case-control study.

INTRODUCTION: Recent studies have reported an increasing incidence of ischaemic stroke among young adults. However, the strength of the association between traditional vascular risk factors has not been fully established. METHODS: We compared 120 patients with a first ischaemic stroke before the age of 55 years admitted to the stroke unit of our centre with 600 healthy non-stroke controls from a population-based cohort study (HERMEX), matched for sex. Risk factors assessed included: hypertension, obesity, auricular fibrillation, current smoking, estimated glomerular filtration rate (eGFR), total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, high-density lipoprotein cholesterol (HDL-C) and diabetes mellitus. We used logistic regression analysis and calculated population attributable risk. We performed an overall analysis, by sex and aetiological subgroup. RESULTS: Using logistic regression analysis, we found that overall, the significant risk factors were: hypertension (OR: 1.58; 95%CI: 1.01-2.50), atrial fibrillation (OR: 4.77; 95%CI: 1.20-19.00), low eGFR (OR: 4.74; 95%CI: 1.3-21.94) and low HDL-C (OR: 5.20; 95%CI: 3.29-8.21), as well as smoking for males (OR: 1.86; 95%CI: 1.14-3.03). LDL-C showed an inverse association with stroke. The population attributable risk for HDL-C was 37.8% and for hypertension 21.1%. In terms of aetiological subgroups, only low HDL-C was associated with stroke of undetermined aetiology. CONCLUSIONS: Hypertension, auricular fibrillation, low eGFR, and low HDL-C, plus tobacco use in men, are the main risk factors among patients under 55 years of age with a first ischaemic stroke. We believe that it would be of particular interest to further explore the management of low HDL-C levels as part of preventive strategies in young stroke patients.

Reporte de caso: vólvulo de sigmoides en un adulto joven, una manifestación de enfermedad de Hirschsprung.

BACKGROUND: Hirschsprung's disease is characterized by the absence of enteric ganglia in the distal digestive tract; being usually diagnosed in neonates, it rarely debuts during adulthood, where it presents as chronic constipation refractory to treatment. CASE REPORT: 24-year-old female patient with Hirschsprung's disease who arrives to the emergency room with a sigmoid volvulus requiring urgent surgical therapy. CONCLUSIONS: Hirschsprung's disease doesn't frequently debut in adulthood, presenting a diagnostic and therapeutic challenge for the general surgeon, especially when dealing with its complications.

ANTECEDENTES: La enfermedad de Hirschsprung se caracteriza por un defecto de las células nerviosas en el intestino distal. Suele diagnosticarse durante los primeros años de vida, rara vez debutando en adultos, en quienes se manifiesta como una constipación crónica refractaria al tratamiento. CASO CLÍNICO: Mujer de 24 años con enfermedad de Hirschsprung no diagnosticada, quien acude a urgencias por un cuadro de vólvulo de sigmoides que requiere intervención quirúrgica. CONCLUSIONES: La enfermedad de Hirschsprung rara vez debuta en la edad adulta y generalmente se diagnostica secundaria a sus complicaciones, por lo que supone un reto diagnóstico y terapéutico para el cirujano general.

Experiences of living with cancer of adolescents and young adults and their families: A narrative review and synthesis.

INTRODUCTION: Adolescence is a critical life stage marked by significant physical, psychological, and social change. Cancer diagnosis during adolescence profoundly affects this experience for adolescents and young adults (AYA) and their families with an impact that continues throughout life. It is important to understand these experiences to ensure delivery of appropriate and high-quality supportive care. This narrative review critically appraised and synthesised qualitative literature that explored the experiences of AYAs and their families living with cancer. METHOD: Narrative review and synthesis of qualitative research of AYAs' and their families' experiences of cancer. MEDLINE, CINAHL and PsycINFO were searched between February 2000 and September 2019 using search terms including "adolescent", "young people", "young adult", "cancer", "family", and "qualitative". Literature was appraised and synthesised using Popay et al.'s1 framework. RESULTS: 3016 articles were retrieved (Medline n=1298, CINAHL n=1632, PsycINFO n=86). Of these, 151 duplicates were removed. 2865 papers were screened with 121 abstracts considered for eligibility for inclusion. Eighteen papers met the inclusion criteria. Three inter-related themes were identified: being diagnosed with cancer; uncertainty - holding on to life and gaps in care delivery. DISCUSSION AND RECOMMENDATIONS: Few studies discuss the impact of cancer on the families of AYA living with cancer. Future research should explore this experience. By doing so the relational impact of cancer will be better understood as the basis of supportive family-centred care. PROSPERO Registration: CRD42017084148.

Is level of anxiety associated with overweight and obesity risk in university students? The NUTSAU Study.

INTRODUCTION: Introduction: effective ways of overcoming overweight may depend, in part, on the ability to identify mood disorders (anxiety is most prevalent) and their association with overeating and weight gain. The use of anthropometric indicators for such purposes can inform individual strategies for intervention before obesity sets in. Objective: to verify the association between anxiety and anthropometric indicators in university students. Methods: a cross-sectional study was conducted in 147 undergraduates across all programmes taught by the Federal University of Rio de Janeiro (UFRJ) at Macaé. A self-assessment questionnaire was administered in order to gather socioeconomic, lifestyle, and anxiety data. Anxiety status was estimated based on the State-Trait Anxiety Inventory (STAI), and interpreted based on the median of scores (p ≥ 50). An anthropometric assessment was conducted to measure the subjects' body mass, body mass index (BMI), and waist circumference (WC). Body fat percentage (%BF) data were obtained using bioelectrical impedance analysis (BIA). The data were then analyzed using the chi-square and logistic regression tests, with a 0.05 significance level. For analysis purposes, anxiety was defined as the exposure variable in the present study, and anthropometric indicators as the outcomes. Results: the students with an anxiety state p ≥ 50 presented an odds ratio (OR) of 2.69 for being overweight (p = 0.02), as well as an OR of 2.77 for having high BF (p = 0.02) in the adjusted models. Conclusion: a higher level of anxiety is associated with anthropometric indicators among university students, specifically for overweight or obesity and high BF percentages.

INTRODUCCIÓN: Introducción: determinar formas efectivas de combatir el sobrepeso puede depender parcialmente de identificar las alteraciones del estado de ánimo, entre las cuales prevalece la ansiedad, y asociarlas al consumo excesivo de alimentos. Puede ser útil utilizar identificaciones antropométricas en tal investigación para definir estrategias personalizadas antes de que aparezca la obesidad. Objetivo: verificar la asociación entre síntomas de ansiedad e indicadores antropométricos en estudiantes universitarios. Metodología: este trabajo es un estudio transversal con 147 estudiantes de graduación de la Universidad Federal de Río de Janeiro en Macaé. Se recopilaron los datos con un cuestionario autocompletado sobre rasgos socioeconómicos, estilo de vida y síntomas de ansiedad. Se estimó el estado de ansiedad considerando el Inventario del Estado de Ansiedad (STAI, por sus siglas en inglés) por encima de la mediana (p > 50). La evaluación antropométrica consistió en medir la masa corporal, el índice de masa corporal (IMC), la circunferencia de la cintura (CC) y el porcentaje de grasa corporal (GC), obtenidos por bioimpedancia eléctrica bipolar. El análisis de datos se realizó mediante pruebas de regresión logística y del chi cuadrado, con el nivel de significancia establecido en 0,05. A efectos del análisis, se definieron como exposición el estado de ansiedad y como resultados los indicadores antropométricos. Resultados: los estudiantes con STAI de p > 50 presentaron una razón de momios (RM) de 2,69 para el sobrepeso (p = 0,02) y de 2,77 para un nivel alto de GC (p = 0,02) en los modelos ajustados. Conclusión: entre los estudiantes universitarios, un nivel de ansiedad más alto se asocia a los indicadores antropométricos de sobrepeso u obesidad y de nivel alto de GC.

[Management of type 2 diabetes mellitus in adolescents and young adults in primary care]. / Manejo de la diabetes mellitus tipo 2 en adolescentes y adultos jóvenes en atención primaria.

The prevalence of type 2 diabetes (DM2) diagnosed in childhood and adolescence is currently increasing, and is characterised by a rapidly progressive decline in beta-cells and insulin resistance. Physical inactivity and obesity are the main risk factors for its development. Diagnostic criteria are similar to those used in adults, although HbA1c as a diagnostic method is questioned. Diabetes-related complications are more aggressive than in adults. Diabetic nephropathy is the most frequent complication in the young population and macrovascular complications appear early, leading to high mortality rates. Healthy lifestyles are the basis of the treatment, and metformin, insulin and liraglutide (approved by FDA for its use in the United States) are the pharmacological options indicated in this population. It is important to establish models of health care transition from paediatric to adult care to ensure continuity of care and avoid patient disengagements.

[Overcoming the difficulty of recruiting young people. Keys to obtaining qualitative data in a study of sexualities]. / Superando la dificultad de captar jóvenes. Claves para la obtención de datos cualitativos en un estudio de sexualidades.

Sexuality is a central aspect of young's lives. It is a task of public health to understand how they are constructed with all their diversity, and to give satisfactory answers in the field of sexual health. The characteristics of qualitative research (flexible, open and reflective) provide the opportunity to design studies that are accepted and adapted to the realities of young people, especially in a sensitive field. The aim of this note is to provide clues for the recruitment of young people. In our case, the knowledge of key informants regarding the study population and the research context was essential, both to choose an approach and recruitment strategy and to adapt the data collection techniques. Finally, we used individual interviews and triangular groups opportunistically in waiting rooms of sexual health care services specialized in young people, where there was already a predisposition to talk about sexuality.

Alcohol, age at first sexual intercourse and number of sexual partners in young Mexican women. / Alcohol, edad de la primera relación sexual y número de parejas sexuales en jóvenes mexicanas.

AIM: To identify the relationship between use of alcohol, number of sexual partners and age of sexual initiation. METHOD: Descriptive-correlational study. A random sample of 319 young women (age 18-25) from Nuevo Laredo, Mexico was recruited. A sociodemographic data sheet and the AUDIT questionnaire were used. Non-parametric Spearman's rank correlation coefficient and Kruskal-Wallis H test were selected. RESULTS: On average the participants were 20.70 years old (±2.1), had had 1.86 sexual partners (±1.27), started drinking alcohol at the age of 16.82 (±1.79), and their first sexual intercourse was at the age of 17.38 (±1.65). There was a decrease in the age of onset of alcohol use (H=16.646, p <.001) and the age at first sexual intercourse (H=26.749, P<.001) on the lower their current age. The overall AUDIT score negatively correlated with the age of the participants on their first sexual intercourse (rs=-.168, P<.001) and positively correlated with the number of sexual partners (rs=.243, P<.001). The aforementioned correlations were more intense among the younger participants (18- and 19-year olds; P<.01). CONCLUSIONS: There was an association between higher use of alcohol, early age of sexual initiation and number of sexual partners. Nursing professionals may address such variables simultaneously through preventive strategies directed specifically at young women.

Conclusiones: Las participantes cuentan con niveles altos de salud sexual, así como de conocimientos y actitudes, sin embargo, presentan un nivel medio de prácticas, situación que vulnera la salud y otros aspectos. Este estudio contribuye a brindar un panorama sobre la salud sexual de las jóvenes, así como algunas variables que enfermería debe considerar para la formulación de programas que coadyuven a fomentar la salud sexual.

Objective: To describe the overall sexual health, as well as specific dimensions, of a group of university women and to determine its relationship with sociodemographic, academic and sexuality characterizing variables. Materials and Methods: Quantitative, descriptive, correlational study, carried out on 91 women from two private universities in Guanajuato (Mexico), using a data sheet and the Sexual Health Scale, with probability sampling for the universities and non-probability sampling for the participants. Descriptive and inferential statistics were used and ethical-legal considerations were followed. Results: 91 women aged 18 to 24 years participated, 74.7% had an active sexual life, reported from one to 11 sexual partners, a mean age of 17 years (SD 1.73) for sexual initiation, showed high levels of sexual health awareness (X114.85; SD 11.50) and a statistically significant relationship was found in variables such as sexual initiation, age at sexual initiation, number of sexual partners, sexually active life and use of contraceptive methods. Conclusions: The participants presented a high level of sexual health awareness, as well as knowledge and attitudes, but they presented a medium level of practices, a situation that is detrimental to health and other aspects. This study aims to provide an overview of the sexual health of young women, as well as some variables that nursing practice should consider when formulating programs that help promote sexual health.

Material e métodos: Pesquisa quantitativa, descritiva, correlacional, realizada com 91 mulheres de duas universidades privadas de Guanajuato (México), usando uma ficha técnica e a Escala de Saúde Sexual, com amostragem probabilística para as universidades e amostragem não probabilística para as participantes. Foram usadas estatísticas descritivas e inferenciais e respeitaram-se os aspectos ético-legais. Resultados: Participaram 91 mulheres de 18 a 24 anos, 74,7% tinham vida sexual ativa, relataram de um a 11 parceiros sexuais, uma idade média de 17 anos (DP 1,73) para o início da vida sexual, apresentaram altos níveis de saúde sexual (x 114,85; DP 11,50) e foi encontrada uma relação estatisticamente significativa em variáveis como início da vida sexual, idade de início da vida sexual, número de parceiros sexuais, vida sexual ativa e uso de métodos contraceptivos. Conclusões: Os participantes apresentaram elevados níveis de saúde sexual, bem como conhecimentos e atitudes, porém apresentaram um nível médio de práticas, situação que prejudica a saúde e outros aspectos. Este estudo tem como objetivo fornecer um panorama sobre a saúde sexual de mulheres jovens, bem como algumas variáveis que a prática de enfermagem deve considerar na formulação de programas que ajudem a promover a saúde sexual.

Variaciones de alfa-amilasa salival relacionadas con edad, sexo e índice de masa corporal en estudiantes universitarios / Variations of salivary alpha-amylase related to age, sex and body mass index in university students

Objetivo. Determinar la presencia y dirección de la relación entre alfa-amilasa salival (AAs), edad, sexo e índice de masa corporal (IMC) en adultos jóvenes. Métodos. Este estudio transversal se desarrolló con una muestra de 50 estudiantes de odontología de 19 a 34 años de edad, 58% mujeres y 42% hombres. Se recogieron muestras de saliva entera sin estimular en la mañana (6:30-7:30 a.m.) y en la tarde (4:00-6:00 p.m.). Los valores de AAs se determinaron mediante método cinético y se expresaron como media ± desviación estándar. Se realizaron análisis descriptivo de datos, prueba de chi-cuadrado, prueba de correlación de Pearson y prueba t de muestras pareadas. Resultados. El IMC promedio fue de 23,85 ± 3,30 kg/m2, 66% de los participantes presentó peso normal (IMC ≤ 25 kg/m2). Los niveles de AAs por la tarde (282,74 ± 59,60 U/ml) fueron mayores a los de la mañana (190,84 ± 61,80 U/ml), (t = 16,51, p < 0,0001). Los hombres mostraron niveles de AAs más altos que las mujeres (p < 0,0001). La edad no mostró asociación con los niveles de AAs. Los valores de IMC y AAs presentaron una correlación positiva (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusión. El nivel de actividad de AAs se puede utilizar como posible biomarcador para evaluar el IMC en relación con el sexo, especialmente en los adultos jóvenes.

Objective. To determine the presence and direction of the relationship between salivary alpha-amylase (sAA), age, sex, and body mass index (BMI) in young adults. Methods. This cross-sectional study was developed with a sample of 50 dental students from 19 to 34 years of age, 58% women and 42% men. Unstimulated whole saliva samples were collected in the morning (6:30-7:30 a.m.) and in the afternoon (4:00-6:00 p.m.). sAA values were determined by the kinetic method and expressed as mean ± standard deviation. Descriptive data analysis, chi-square test, Pearson correlation test, and paired samples t-test were made. Results. Mean BMI was 23.85 ± 3.30 kg/m2, 66% of the participants presented normal weight (BMI ≤ 25 kg/m2). Levels of sAA in the afternoon (282.74 ± 59.60 U/ml) were higher than those in the morning (190.84 ± 61.80 U/ml), (t = 16.51, p < 0, 0001). Men showed higher levels of sAA than women (p < 0.0001). Age did not show an association with sAA levels. BMI and AAs values presented a positive correlation (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusions. AAs activity level can be used as a potential biomarker to assess BMI in relation to sex, especially in young adults.
