Panorama of risky sexual behaviors in the Brazilian adult population - PNS 2019.

OBJECTIVE: To describe the risky sexual behaviors of Brazilian adults according to socioeconomic, demographic, and regional characteristics. METHODS: Data from the 2019 National Health Survey, referring to the population aged 18 years or older, were analyzed. Risky sexual behaviors were considered: early sexual initiation, before the age of 15 years, and nonuse of condoms in the last sexual intercourse. Prevalence and respective confidence intervals were calculated for the subgroups of interest. RESULTS: Early sexual initiation among adult individuals was 24% among men and 11% among women, being higher among young people with lower levels of education and household income. The nonuse of condoms was higher among married/cohabiting partners, no schooling or with some elementary school, and among older people. The prevalence of nonuse of condoms among married/cohabiting partners was the same in both sexes (75%). However, among non-cohabiting partners, gender disparity was relevant, as 39.1% of women did not use condoms in the last sexual intercourse, while among men this result was 26.9%. CONCLUSIONS: Higher prevalence of early sexual initiation for younger generations is noteworthy, especially among women. Concerning the nonuse of condoms, there are important gender disparities in the group of non-cohabiting partners, in addition to the high prevalence among older people, which should be considered in the formulation of public policies. The results of the present study are extremely relevant for understanding the adult population currently more vulnerable to sexually transmitted infections, after over five years without official statistics on this matter at the national level.

Trend in the prevalence of depressive symptoms in Brazil: results from the Brazilian National Health Survey 2013 and 2019.

This study aims to evaluate national variation in depression prevalence and in different sociodemographic groups, health behaviors, and macroregions of Brazil from 2013 to 2019. Data were obtained from two nationwide Brazilian surveys - Brazilian National Health Survey 2013 and 2019. Participants aged 18 years or older were included, totaling 60,202 individuals in 2013 and 88,531 in 2019. Depression was evaluated with the Patient Health Questionnaire-9 (PHQ-9). All estimations accounted for the population weights and the complex sampling. The findings showed that during the six years between the two surveys, the prevalence of depression in Brazil increased by 36.7%, going from 7.9% in 2013 to 10.8% in 2019, and this increase is higher among unemployed young adults, aged 18 to 24 years, with the increase in the prevalence of depression almost tripled (3.7 in 2013 and 10.3 in 2019), an increase of 178.4%. Those dwelling in urban areas had a higher increase in the prevalence of depression in the six-year period (39.8%) when compared to residents in rural areas (20.2%). There was an increase in the prevalence of depression from 2013 to 2019 for the worst categories of the three health behaviors included in the study for both men and women: heavy drinking, smoking, and not exercising the recommended level of physical activity. Our results show a significant increase in the prevalence of depression over the six years between the two surveys, mainly among the younger and unemployed men. The country's economic recession during this period may explain these findings.

Comportamentos sexuais de risco, orientação sexual, uso de substâncias e saúde mental: Um estudo de base populacional no Brasil / Risky sexual behaviors, sexual orientation, substance use, and mental health: A population-based study in Brazil

A presente tese trata-se de um estudo de prevalências e associações no âmbito da sexualidade e dos comportamentos sexuais. Foram utilizados os dados do novo módulo de atividade sexual incluído na Pesquisa Nacional de Saúde (PNS) em 2019 voltado para a população de 18 anos ou mais de idade (n=85.859). No primeiro artigo, foi traçado um panorama dos comportamentos sexuais de risco na população adulta relacionados ao não uso de preservativo na última relação sexual e à iniciação sexual precoce (antes dos 15 anos). Foram calculadas as prevalências, e respectivos intervalos de confiança (IC), dos desfechos segundo características socioeconômicas, demográficas e regionais da população. Observou-se que a iniciação sexual precoce é mais prevalente entre pessoas das gerações mais novas, com menores níveis de instrução e rendimento domiciliar. O não uso de preservativo foi mais prevalente entre mulheres, mais velhos e casados ou em coabitação. Foram observadas disparidades relevantes no não uso do preservativo entre os sexos no grupo dos que não coabitam com parceiro. No segundo artigo, avaliou-se a associação entre o consumo pesado de álcool e o uso inconsistente de preservativo entre pessoas de 18 a 59 anos solteiras, viúvas ou divorciadas que não coabitavam com parceiro (n=15.835). Foram estimadas razões de prevalências ajustadas (RPa) com modelos de regressão de Poisson estratificados por sexo e grupos de idade. Verificou-se que indivíduos de todas as faixas etárias e ambos os sexos com padrão de consumo pesado de álcool foram significativamente mais propensos ao uso inconsistente de preservativo que os demais. As estimativas obtidas não foram consideradas estatisticamente diferentes entre adultos jovens (RPa 1,32, IC 95%: 1,14-1,54) e de meia idade (RPa 1,31; IC 95%: 1,19-1,44 para pessoas de 25 a 39 e RPa 1,26; IC 95%: 1,13-1,40 para 40 a 59 anos). No terceiro e último artigo da presente tese, o uso de substâncias (álcool e tabaco) e a depressão foram analisados segundo a orientação sexual autoidentificada da população adulta. Foram estimadas as prevalências e razões de prevalência ajustadas por meio de modelos de regressão de Poisson estratificados por sexo para cada um dos desfechos analisados. Após controle por covariáveis, homens gays apresentaram maior prevalência de depressão, uso diário de tabaco e uso nocivo de álcool e tabaco (RPa entre 1,71 e 1,92) e homens bissexuais com maiores prevalências (quase três vezes) de depressão que homens heterossexuais. Mulheres lésbicas apresentaram maior prevalência de binge drinking, heavy drinking, uso diário de tabaco e uso nocivo de álcool e tabaco que mulheres heterossexuais (RPa entre 2,55 e 4,44). Entre as mulheres bissexuais os resultados foram significativos para todos os desfechos analisado (RPa variou entre 1,83 e 3,26). Sendo assim, essa tese fornece evidências relevantes para subsidiar ações em saúde pública que visem a redução de comportamentos sexuais de risco e das disparidades em saúde relacionadas a orientação sexual da população adulta brasileira.

This thesis is a study of prevalence and associations in the scope of sexuality and sexual behavior. Data are from the new module of sexual activity included in the National Health Survey (PNS, for its Portuguese acronym) in 2019, aimed at the population aged 18 and over (n=85,859). In the first article, a panorama of risky sexual behaviors in the adult population related to the non-use of condoms in the last sexual intercourse and early sexual initiation (before 15 years of age) was performed. Prevalence, and respective confidence intervals (CI), of the outcomes were calculated according to socioeconomic, demographic and regional characteristics of the population. It was observed that early sexual initiation is more prevalent among younger generations, with lower education levels and household income. Non-use of condoms was more prevalent among women, older people and married/cohabiting with a partner. Relevant disparities in non-use of condom between the sexes were observed in the non-cohabiting unmarried group. In the second article, the association between heavy alcohol consumption and inconsistent condom use was investigated among unmarried not cohabiting with a partner people aged 18 to 59 years (n=15,835). Adjusted prevalence ratios (APR) were estimated with Poisson regression models stratified by sex and age groups. It was observed that individuals from all age groups and both sexes who have heavy drinking pattern were significantly more likely to inconsistent condom use. The estimates were not considered statistically different between young (APR 1.32, 95% CI: 1.14-1.54) and middle-aged adults (APR 1.31; 95% CI: 1.19-1.44 for aged 25 to 39 and APR 1.26; 95% CI: 1.13-1.40 for aged 40 to 59 years). In the third and last article of this thesis, substance use (alcohol and tobacco) and depression were analyzed according to the self-identified sexual orientation of the adult population. Prevalence and adjusted prevalence ratios were estimated using Poisson regression models stratified by sex for each outcome. After controlling for covariates, gay men had a higher prevalence of depression, daily tobacco use and hazardous use of alcohol and tobacco (APR between 1.71 and 1.92) and bisexual men had a higher prevalence (almost three times) of depression than heterosexual men. Lesbian women had a higher prevalence of binge drinking, heavy drinking, daily tobacco use and hazardous use of alcohol and tobacco than heterosexual women (APR between 2.55 and 4.44). Among bisexual women, the results were significant for all outcomes analyzed (APR ranged between 1.83 and 3.26). Therefore, this thesis provides relevant evidence to support public health actions aimed at reducing risky sexual behavior and health disparities related to sexual orientation in the Brazilian adult population.

O estudo objetiva avaliar a variação nacional na prevalência geral da depressão e em diferentes grupos sociodemográficos, comportamentos de saúde e macrorregiões do Brasil entre 2013 e 2019. Os dados foram obtidos de dois inquéritos brasileiros de abrangência nacional, a Pesquisa Nacional de Saúde (PNS) 2013 e a 2019. Entre os participantes com idade de 18 anos ou mais, houve 60.202 indivíduos em 2013 e 88.531 em 2019. A depressão foi avaliada com o Questionário de Saúde do Paciente-9 (PHQ-9). Todas as estimativas levaram em conta os pesos populacionais e a amostragem complexa. Os achados mostraram que durante os seis anos entre as duas edições da PNS, a prevalência de depressão no Brasil aumentou em 36,7%, de 7,9% em 2013 para 10,8% em 2019, com um aumento ainda maior em adultos jovens, no grupo etário de 18 a 24 anos, e naqueles que não estavam trabalhando, onde houve um aumento de quase três vezes na prevalência de depressão (3,7% em 2013 e 10,3% em 2019), ou seja, um aumento de 178,4%. Indivíduos residindo em áreas urbanas tiveram um aumento maior na prevalência de depressão ao longo do período de seis anos (39,8%), em comparação com os residentes em áreas rurais (20,2%). Houve um aumento na prevalência de depressão entre 2013 e 2019 para as piores categorias dos três comportamentos de saúde incluídos no estado, tanto em homens quanto em mulheres: etilismo, tabagismo e sedentarismo. Nossos resultados mostram um aumento significativo na prevalência de depressão nos seis anos entre as duas edições da PNS, principalmente entre homens mais jovens e desempregados. A recessão econômica no Brasil durante o período pode explicar esses achados.

El objetivo de este estudio es evaluar la variación nacional en la prevalencia general de depresión, así como en diferentes grupos sociodemográficos, comportamientos de salud, y macrorregiones del país entre 2013-2019. Los datos se obtuvieron de dos encuestas nacionales brasileñas -Encuesta Nacional de Salud 2013 y 2019-. Los participantes con edades entre los 18 años y con más edad incluyeron a 60 202 personas en 2013 y 88 531 en 2019. La depresión se evaluó mediante el Cuestionario de Salud del Paciente-9 (PHQ-9). Todas las estimaciones justificaron los pesos de la población y el muestreo complejo. Los resultados mostraron que durante seis años entre las dos encuestas, la prevalencia de depresión en Brasil se incrementó en un 36,7%, yendo de un 7,9% en 2013 a un 10,8% en el 2019, y este incremento es mayor entre adultos jóvenes, de 18 a 24 años de edad, que no estaban trabajando, donde casi había un incremento tres veces superior en la prevalencia de depresión (3,7 en 2013 y 10,3 en 2019), un incremento de un 178,4%. Aquellos que vivían en áreas urbanas tenían un incremento mayor en la prevalencia de depresión durante el período de seis años (39,8%), cuando se comparó con los residentes en áreas rurales (20,2%). Hubo un incremento en la prevalencia de depresión entre 2013-2019 para las peores categorías de los tres comportamientos de salud incluidos en el estudio para tanto hombres como mujeres: consumo excesivo de alcohol, fumar, y no practicar deporte al nivel recomendado de actividad física. Nuestros resultados muestran un significado incremento en la prevalencia de depresión durante los seis años entre las dos encuestas, principalmente entre los hombres más jóvenes y desempleados. La recesión económica del país durante este periodo puede explicar estos resultados.

RESUMO OBJETIVO Descrever os comportamentos sexuais de risco dos adultos brasileiros segundo características socioeconômicas, demográficas e regionais. MÉTODOS Foram analisados dados da Pesquisa Nacional de Saúde 2019, referente à população de 18 anos de idade ou mais. Considerou-se como comportamentos sexuais de risco: a iniciação sexual precoce, antes dos 15 anos, e o não uso de preservativo na última relação sexual. Foram calculadas as prevalências e respectivos intervalos de confiança para os subgrupos de interesse. RESULTADOS A iniciação sexual precoce entre indivíduos adultos foi de 24% entre os homens e 11% entre as mulheres, sendo mais alta entre jovens com menores níveis de instrução e rendimento domiciliar. O não uso de preservativo se mostrou maior entre os casados/coabitantes, sem instrução ou com nível fundamental incompleto, e entre os mais velhos. A prevalência do não uso de preservativo entre casados/coabitantes foi igual em ambos os sexos (75%). No entanto, entre os não coabitantes, a disparidade entre os sexos se mostrou relevante uma vez que 39,1% das mulheres não usaram preservativo na última relação sexual, enquanto entre os homens esse resultado foi de 26,9%. CONCLUSÃO Nota-se, especialmente entre as mulheres, maiores prevalências de iniciação sexual precoce para as gerações mais novas. No que se refere ao não uso de preservativo, há disparidades de sexo importantes no grupo dos não coabitantes, além da alta prevalência entre os mais velhos, que devem ser consideradas na elaboração das políticas públicas. Os resultados do presente estudo são extremamente relevantes para compreensão da população adulta atualmente mais vulnerável às infecções sexualmente transmissíveis, após mais de cinco anos sem estatísticas oficiais a respeito em âmbito nacional.

Trend in the prevalence of depression and correlates in Brazil: results from the National Health Surveys 2013 and 2019

This study aims to evaluate national variation in depression prevalence overall and in different socioeconomic and demographic groups, health behaviors, and macro-regions of the country, between 2013 and 2019. Data were obtained from the National Health Surveys ­ PNS 2013 and 2019, which are cross-sectional surveys of the Brazilian general population. Participants aged 18 years and older included 60,202 individuals in 2013 and 88,531 in 2019. Depression was evaluated through the Patient Health Questionnaire-9 (PHQ-9). Calculations were carried out population-weighted. Additional age-standardized analyses were conducted to account for demographic changes. The results showed that in the six-year period between the two surveys, the prevalence of depression in Brazil increased by 36.7%, going from 7.9% in 2013 to 10.8% in 2019, this increase is more marked among young adults, 18 to 24 years old, who were not working, where there was a significant and almost three-fold absolute difference increase in the prevalence of depression (3.7 in 2013 and 10.3 in 2019), an increase of 178.4%. Those living in urban areas of the country had a greater increase in the prevalence of depression in the six-year period (39.8%) when compared to residents in rural areas (20.2%). There was an increase in the prevalence of depression between 2013 and 2019 for the worst categories of the three health behaviors under study, for both sexes: heavy drinking, smoking, and lack of physical activity, following the pattern observed for the general population. Our results show evidence of a significant increase in the prevalence of depression over the six-year period between the two surveys, mainly among the younger and unemployed men. The country´s economic context of recession during this period may be an explanation for this finding.

Self-reported prevalence of disability in Brazil, according to the National Health Survey, 2013. / Prevalência autorreferida de deficiência no Brasil, segundo a Pesquisa Nacional de Saúde, 2013.

OBJECTIVE: To describe the self-reported prevalence of intellectual disability, physical, hearing and visual, according to sociodemographic variables, degree of limitation and frequency of rehabilitation service use. METHODS: Data from the National Health Survey, a population survey. the self-reported prevalence of physical, mental, visual and hearing were calculated and their 95% confidence intervals, stratified by sex, age, race / color, for Brazil, place of residence and Major Regions. RESULTS: The prevalence of self-reported disability in the country was 6.2% (12.4 million people). The prevalence of disability was 1.3% higher in men, in people aged 60 or more in the Northeast. Visual impairment was more prevalent (3.6%), increased with age, as well as hearing loss. Acquired deficiency was higher in relation to the birth (except intellectual). Lesser degree of limitation was observed among those who reported visual impairment and the use of health services was less frequent. CONCLUSION: It is necessary to expand access to health promotion, early diagnosis and treatment, as well as strengthen public policies aimed at this population.

Resumo Objetivo descrever a prevalência autorreferida das deficiências intelectual, física, auditiva e visual, segundo variáveis sociodemográficas, grau de limitação e frequência de uso de serviço de reabilitação. Métodos Dados provenientes da Pesquisa Nacional de Saúde, inquérito populacional. Foram calculadas as prevalências autorreferidas de deficiência física, mental, visual e auditiva e seus intervalos de confiança de 95%, estratificados por sexo, faixa etária, raça/cor, para Brasil, local de residência e Grandes Regiões. Resultados a prevalência de deficiência autorreferida no país foi de 6,2% (12,4 milhões de pessoas). A prevalência de deficiência física foi de 1,3%, maior em homens, em indivíduos com 60 anos ou mais na região Nordeste. A deficiência visual foi mais prevalente (3,6%), aumentou com a idade, assim como deficiência auditiva. A deficiência adquirida foi maior em relação à de nascença (exceto intelectual). Menor grau de limitação foi observado entre os que referiram deficiência visual e o uso de serviços de saúde foi menos frequente. Conclusão há necessidade de ampliar o acesso às ações de promoção, diagnóstico e tratamento precoce, bem como o fortalecer políticas públicas direcionadas a esta população.

A vigilância e o monitoramento das principais doenças crônicas não transmissíveis no Brasil - Pesquisa Nacional de Saúde, 2013 / Surveillance and monitoring of major chronic diseases in Brazil - National Health Survey, 2013

RESUMO: Objetivo: Descrever as principais doenças crônicas não transmissíveis (DCNT) no país segundo as informações coletadas em indivíduos de 18 anos ou mais de idade. Métodos: Foram utilizados dados da Pesquisa Nacional de Saúde (PNS), 2013, estudo transversal de base populacional. As proporções de cada DCNT foram calculadas e apresentadas segundo sexo, com intervalo de confiança de 95% (IC95%), com os valores absolutos. Resultados: Do total de entrevistados, 45,1% referiram ter pelo menos uma DCNT. A Região com maior prevalência de DCNT foi a Sul (52,1%). A hipertensão arterial apresentou a maior prevalência dentre as DCNT, com 21,4%, seguida por problema crônico de coluna (18,5%), depressão (7,6%), artrite (6,4%) e diabetes (6,2%). O grau de limitação intenso/muito intenso apresentou maiores prevalências para outra doença mental (37,6%) e acidente vascular cerebral (AVC) (25,5%). Conclusão: A melhoria dos serviços de saúde é indispensável para uma resposta efetiva à dupla carga de adoecimento de países de média e baixa renda.

ABSTRACT: Objective: To describe the major noncommunicable diseases (NCDs) in Brazil, according to the information collected from individuals aged 18 years or older. Methods: Data from the National Health Survey (PNS), 2013, a transversal population-based study, were used. The proportions of each NCD were calculated and presented according to sex, with a 95% confidence interval (95%CI), with the absolute values. Results: Of the total respondents, 45.1% reported presenting at least one NCD. The region with the highest prevalence of NCDs was the South (52.1%). Hypertension showed the highest prevalence among NCDs, with 21.4%, followed by chronic back problem (18.5%), depression (7.6%), arthritis (6.4%), and diabetes (6.2%). The intense/very intense degree of limitation showed a higher prevalence of other mental illnesses (37.6%) and cerebrovascular accident (25.5%). Conclusion: The improvement of health services is essential for an effective response to the double burden of illness in the middle- and low-income countries.

Use of tranexamic acid for controlling bleeding in thoracolumbar scoliosis surgery with posterior instrumentation.

OBJECTIVE: Scoliosis surgery involves major blood loss and frequently requires blood transfusion. The cost and risks involved in using allogeneic blood have motivated investigation of methods capable of reducing patients' bleeding during operations. One of these methods is to use antifibrinolytic drugs, and tranexamic acid is among these. The aim of this study was to assess the use of this drug for controlling bleeding in surgery to treat idiopathic scoliosis. METHODS: This was a retrospective study in which the medical files of 40 patients who underwent thoracolumbar arthrodesis by means of a posterior route were analyzed. Of these cases, 21 used tranexamic acid and were placed in the test group. The others were placed in the control group. The mean volumes of bleeding during and after the operation and the need for blood transfusion were compared between the two groups. RESULTS: The group that used tranexamic acid had significantly less bleeding during the operation than the control group. There was no significant difference between the groups regarding postoperative bleeding and the need for blood transfusion. CONCLUSIONS: Tranexamic acid was effective in reducing bleeding during the operation, as demonstrated in other studies. The correlation between its use and the reduction in the need for blood transfusion is multifactorial and could not be established in this study. We believe that tranexamic acid may be a useful resource and that it deserves greater attention in randomized double-blind prospective series, with proper control over variables that directly influence blood loss.

OBJETIVO: A cirurgia de escoliose envolve elevada perda sanguínea e necessita frequentemente de hemotransfusão. O custo e os riscos envolvidos no uso do sangue alogênico têm motivado pesquisas de métodos capazes de reduzir o sangramento operatório nos pacientes. Um desses métodos é o uso de drogas antifibrinolíticas, entre as quais está o ácido tranexâmico (ATX). O objetivo deste estudo foi verificar o uso dessa droga no controle do sangramento em cirurgias de escoliose idiopática. MÉTODOS: Estudo retrospectivo no qual foram analisados os prontuários de 40 pacientes submetidos à artrodese toracolombar por via posterior. Desses, apenas 21 usaram o ATX e foram relacionados no grupo teste. Os demais foram relacionados no grupo controle. Foram comparadas as médias de sangramento per e pós-operatório e a necessidade de hemotransfusão entre os dois grupos. RESULTADOS: O grupo que usou o ATX teve sangramento peroperatório significativamente menor do que o grupo controle. Não houve diferença significativa entre os grupos para o sangramento pós-operatório e a necessidade de hemotransfusão. CONCLUSÕES: O ATX foi eficaz na redução do sangramento peroperatório, conforme demostrado em outros estudos. A correlação entre o seu uso e a redução da necessidade de hemotransfusão é multifatorial e não pôde ser estabelecida neste trabalho. Acreditamos que o ácido tranexâmico possa ser um recurso útil e merece maior atenção em séries prospectivas, duplo-cegas, randomizadas, com o devido controle das variáveis que interferem diretamente na perda sanguínea.
