Determinants of inequalities in the quality of Brazilian diet: trends in 12-year population-based study (2003-2015).

BACKGROUND: Recent studies have explored the influence of socioeconomic inequalities on the diet quality. However, there is lack of evidence regarding the level of inequalities in dietary quality and its main contributing factors from population-based follow-up studies. The primary objective of this study was to investigate the level and the determinants of inequalities in diet quality in a representative sample of adolescents, adults and older adults resident in São Paulo, Brazil. METHODS: Data from the Health Survey of São Paulo (ISA-Capital) were analyzed for 2003 (n = 2398), 2008 (n = 1662) and 2015 (n = 1742) surveys. Information on food consumption was obtained through 24-h dietary recall, and diet quality was assessed based on the Revised Brazilian Healthy Eating Index (BHEI-R). The descriptive variables were compared using 95% confidence interval. The scores of BHEI-R and its components were compared across age groups and year. The association between socioeconomic inequalities and diet quality was based on the estimation of concentration index. RESULTS: We observed that the BHEI-R scores gradually improved over 12-years, with older adults showing the greatest improvement. The increase in overall population score was observed for total fruits, whole fruits, whole grains, oils and sodium. The main contributor to socioeconomic inequality in diet quality in 2003 was ethnic group, and in 2008 and 2015, it was per capita household income; age was a persistent factor of inequality in the population over the years. Concentration indices indicated that lower income individuals had higher BHEI-R scores in 2003; however, there was a shift in favor of higher income individuals in 2008 and 2015. CONCLUSIONS: Changes in the patterns of determination of inequalities according to age, ethnic group or income during the period analyzed show the existence of ongoing process of contribution of demographic and socioeconomic factors in the diet quality of individuals in a large urban center.

Excess body weight in the city of São Paulo: panorama from 2003 to 2015, associated factors and projection for the next years.

BACKGROUND: Excess body weight (EBW: overweight and obesity) has high and rising prevalence in Brazil. Up-to-date information about the distribution and changes in the prevalence of EBW and their associated factors are essential to determine target groups and to identify priority actions. The aim of this study was to investigate the associated factors and to determine the prevalence of overweight and obesity in the adolescent and adult population of the city of São Paulo in the years of 2003, 2008, and 2015, as well as to estimate the prediction for the next years. METHODS: Individuals aged 12 years and older from three editions of the Health Survey of São Paulo (ISA-Capital), a cross-sectional population-based survey, carried out in 2003 (n = 2144), 2008 (n = 2599), and 2015 (n = 3939), had their socioeconomic, anthropometric, and lifestyle data collected at households. Individuals were classified according to their age and BMI as: without excess body weight, overweight, or obese. Differences were evaluated through Pearson's Chi-square test and comparison of 95% CI. Generalized ordered logit models were used to evaluate factors associated to overweight/obesity and logistic regression models were used to predict their prevalence for the next years. RESULTS: The prevalence (95% CI) of obesity in total population doubled: from 10% (8.0, 12.5) in 2003 to 19.2% (17.8, 20.6) in 2015. The main increase occurred in female adolescents from 2.5% (1.2, 5.3) to 11.2% (8.4, 14.7) and adults, from 9.2% (6.4, 13.1) to 22.3% (20.0, 24.8). Those with higher chance of having EBW were adults, those with higher income, and former smokers. The prevalence of EBW increased 31% from 2003 to 2008, and 126% from 2003 to 2015, when half of the population had EBW. If this pattern does not change, 77% of the population is expected to have EBW by 2030. CONCLUSIONS: Our findings present up-to-date information about the distribution of EBW, which increased substantially over a short time and more prominently in specific groups. The factors associated with EBW may provide important information for decision makers and researchers to create or review the existing programs and interventions in order to decrease the trend for the next years.

The Brazilian primary health care response to the COVID-19 pandemic: individual and collective approaches.

Objectives: Brazil's PHC wide coverage has a potential role in the fight against COVID, especially in less developed regions. PHC should deal with COVID-19 treatment; health surveillance; continuity of care; and social support. This article aims to analyze PHC performance profiles during the pandemic, in these axes, comparing the five Brazilian macro-regions. Methods: A cross-sectional survey study was carried out, using stratified probability sampling of PHC facilities (PHCF). A Composite Index was created, the Covid PHC Index (CPI). Factor analysis revealed that collective actions contrastingly behaved to individual actions. We verified differences in the distributions of CPI components between macro-regions and their associations with structural indicators. Results: Nine hundred and seven PHCF participated in the survey. The CPI and its axes did not exceed 70, with the highest value in surveillance (70) and the lowest in social support (59). The Individual dimension scored higher in the South, whereas the Collective dimension scored higher in the Northeast region. PHCF with the highest CPI belong to municipalities with lower HDI, GDP per capita, population, number of hospitals, and ICU beds. Conclusion: The observed profiles, individually and collectively-oriented, convey disputes on Brazilian health policies since 2016, and regional structural inequalities.

Changes in total physical activity, leisure and commuting in the largest city in Latin America, 2003-2015.

OBJECTIVE: To analyze the prevalence of physical inactivity and the average time of practice of total physical activity and by domains (leisure and commuting), according to gender, age group and schooling, between 2003 and 2015, in residents of the urban area of the city of São Paulo. METHODS: Data from Household Health Surveys in the Municipality of São Paulo (2003: n = 2,514; 2015: n = 4,043). The International Physical Activity Questionnaire was used to measure total, leisure, and commuting physical activity. Results were presented in < 10 minute/week periods, physical inactivity and minutes/week, according to evaluation period, sex, age and schooling. RESULTS: Prevalence of < 10 minutes/week periods in 2003 and 2015 were: 22.5 and 28.9% for the total; 56.7 and 58.3% for leisure; and 35.2 and 39.9% for commuting, with significant change only in the total item, among adolescents (10.3 to 18.8%). For physical inactivity, prevalence rates were: 54.9 and 61.6% (total); 78.2 and 78.9% (leisure); and 72 and 79.9% (commuting), with significant changes only for commuting among adults (67.8 to 77.4%). For the average in minutes per week, in total, there was a significant decrease for female adolescents (138.2 minute/week) and adults with 0-8 (122.6 minutes/week) and 9-11 years (96.7 minutes/week) years of schooling; in commuting, there was a reduction for female adolescents (95 minutes/week); and male adults (95 minutes/week) and female adults (82 minutes/week). CONCLUSIONS: There were no reductions in the prevalence of < 10 min/week periods or leisure physical inactivity. Commuting physical inactivity has become even more common.

Assessment of initial SARS-CoV-2 seroprevalence in the most affected districts in the municipality of São Paulo, Brazil.

BACKGROUND: São Paulo city has been one of the regions most affected by the COVID-19 pandemic in Brazil. Frequent asymptomatic and oligosymptomatic infections and poor access to diagnostic tests make serosurveys crucial to monitor the magnitude of the epidemic and to inform public health policies, such as vaccination plans. OBJECTIVES: To estimate, early in the epidemic, the seroprevalence of antibodies to SARS-CoV-2 in adults living in the six most affected districts in São Paulo city, and to assess potential associated risk factors. METHODS: This was a cross-sectional population-based survey of 1,152 households randomly selected from 72 census tracts. During the period May 4-12, 2020, 463 participants completed a questionnaire on sociodemographic characteristics and history of symptoms in the past two weeks, and provided a blood sample. Prevalence of SARS-CoV-2 antibodies was the outcome of interest and was estimated based on results of two immunoassays, Maglumi SARS-CoV-2 chemiluminescence assay Immunoglobulin (Ig) M (IgM) and IgG, and Roche electrochemiluminescence assay total Ig. Serum samples reactive to either assay were considered positive. RESULTS: Weighted overall seroprevalence was 6% (95%CI 3.9-8.3%). No association was observed between seropositivity and sex, age group or education level. Participants who reported black and brown skin color showed a 2.7 fold higher prevalence than people with white skin (p = 0.007). Among the 30 seropositive individuals, 14 (46.6%) reported no COVID-19 compatible symptoms in the past two weeks. CONCLUSION: This study represents the first assessment of SARS-CoV-2 seroprevalence in the city of São Paulo and 6% is the baseline estimate of a series of population-based seroprevalence surveys. Serological screening using sound serological assays is the key tool to monitoring temporal and geographic changes in the spread of the virus through an important epicenter of the COVID-19 pandemic in Brazil. Ultimately, it may inform prevention and control efforts.

Prevalence of hypertension in adults in the city of São Paulo and associated factors. / Prevalência de hipertensão arterial em adultos no município de São Paulo e fatores associados.

OBJECTIVE: To analyze the behavior of the prevalence of hypertension in the city of São Paulo and its associated factors. METHODS: The present study used data from the Health Survey in the Municipality of São Paulo (ISA Capital), a population-based cross-sectional study conducted in São Paulo. Data from 1,667 and 3,184 individuals were analyzed in 2003 and 2015, respectively, aged 20 years and over. Descriptive analyzes of the prevalence of hypertension were performed with 95% confidence intervals. Simple and multiple analyzes were performed to analyze the possible associations with socioeconomic, demographic and lifestyle variables by Poisson regression. RESULTS: The prevalence of hypertension increased from 17.2% in 2003 to 23.2% in 2015. The associated variables with hypertension were: gender (females); age (60 years old and over); marital status (married, separated and widowed); having a religion; low education level; being born in the state of São Paulo (except capital); nutritional status (low weight, overweight and obesity); former smokers. CONCLUSION: The prevalence of self-reported hypertension increased significantly in the study period. Considering this disease's impact on society, knowing its current prevalence and identifying its main associated factors, the need to intensify the efforts to prevent it disease is evident in order to mitigate damage to individuals and impact on public expenditure.

OBJETIVO: Analisar o comportamento da prevalência de hipertensão arterial no município de São Paulo e seus fatores associados. MÉTODOS: O presente trabalho utilizou os dados do Inquérito de Saúde no Município de São Paulo (ISA Capital), estudo transversal de base populacional executado no município de São Paulo. Foram utilizados dados de 1.667 e de 3.184 indivíduos em 2003 e 2015, respectivamente, com idade de 20 anos e mais. Fizeram-se análises descritivas das prevalências de hipertensão arterial com respectivos intervalos de 95% de confiança. Análises simples e múltiplas foram realizadas para analisar possíveis associações com as variáveis socioeconômicas, demográficas e de estilo de vida por meio de regressão de Poisson. RESULTADOS: A prevalência de hipertensão arterial passou de 17,2% em 2003 para 23,2% em 2015. Os fatores associados à hipertensão foram: sexo feminino; idade (60 anos e mais); situação conjugal (casados, separados e viúvos); ter religião; baixa escolaridade; ter nascido no estado de São Paulo (exceto capital); estado nutricional (baixo peso, sobrepeso e obesidade); e ex-fumantes. CONCLUSÃO: A prevalência de hipertensão autorreferida aumentou significativamente no período estudado em São Paulo. Considerando o impacto dessa doença na sociedade, conhecendo sua atual prevalência e identificando seus principais fatores associados, evidencia-se a necessidade de intensificar atividades que contribuam para a prevenção desse agravo, atenuando os danos aos indivíduos e gastos públicos.

[Differences in contraceptive practice in the city of São Paulo, Brazil: results of the Ouvindo Mulheres population survey]. / Diferenciais da prática contraceptiva no Município de São Paulo, Brasil: resultados do inquérito populacional Ouvindo Mulheres.

Contraception is essential for women to be able to regulate their fertility, exercising a key dimension of reproductive rights. However, little is known about how women deal with this challenge in Brazil's largest city, São Paulo. To fill this gap, the population survey Ouvindo Mulheres: Contracepção no Município de São Paulo was conducted with a probabilistic sample of 4,000 women 15 to 44 years of age living in this city in 2015. This article presents the prevalence of contraceptive practice and analyzes factors associated with lack of contraception use and with types of contraceptives. Prevalence of contraception was estimated for women with at least one heterosexual relation in the 12 months prior to the interview and who were not pregnant. Logistic regression was used to verify factors associated with lack of contraception use, and the CHAID model was used to identify associations with the types of contraceptives used. Prevalence of contraception was 84.8% (95%CI: 83.2-86.3). The most prevalent contraceptives were the pill and condoms. Factors associated with lack of contraceptive use were religion (Pentecostal), number of children (fewer than 3), not having used contraceptives in the first sexual relation, not having a partner, and not having had sex in the previous month. Number of children and woman's age were the first two levels of discrimination of the types of contraceptives used. Prevalence of contraception was high, but maintaining a concentration in two methods: historically, female sterilization and the pill prevailed, nowadays, the pill and condoms do. New hormonal contraceptives should be incorporated by the Brazilian Unified National Health System (SUS), besides promoting the use of long-acting methods such as IUDs.

A contracepção é fundamental para que as mulheres possam regular sua fecundidade, exercendo uma das dimensões dos direitos reprodutivos. No entanto, desconhecemos como elas enfrentam esse desafio na maior cidade do Brasil, São Paulo. Para preencher essa lacuna, o inquérito populacional Ouvindo Mulheres: Contracepção no Município de São Paulo foi realizado junto a uma amostra probabilística de 4 mil mulheres com 15 a 44 anos de idade, residentes nessa cidade, em 2015. Neste artigo, apresenta-se a prevalência da prática contraceptiva, analisam-se os fatores associados ao não uso de contracepção e aos tipos de contraceptivos em uso. A prevalência da anticoncepção foi estimada para mulheres com, pelo menos, uma relação heterossexual nos 12 meses anteriores à entrevista e que não estavam grávidas. Regressão logística foi utilizada para verificar fatores associados ao não uso de contracepção, e o modelo CHAID, para identificar associações aos tipos de contraceptivo em uso. A prevalência da anticoncepção foi 84,8% (IC95%: 83,2-86,3). Os contraceptivos mais prevalentes foram pílula e preservativo masculino. Associaram-se ao não uso de anticoncepção, religião (Pentecostal), número de filhos (menos do que 3), não ter usado contraceptivo na primeira relação sexual, não ter parceiro e não ter tido relação sexual no mês anterior. O número de filhos tidos e a idade da mulher foram os dois primeiros níveis de discriminação dos tipos de contraceptivo utilizados. A prevalência da anticoncepção é alta, mas mantém-se a concentração em dois métodos: anteriormente, laqueadura e pílula, agora, pílula e preservativo masculino. É necessário incorporar novos contraceptivos hormonais no Sistema Único de Saúde (SUS) e promover o uso de métodos de longa duração como o DIU.

La prevalencia de la anticoncepción fue 84,8% (IC95%: 83,2-86,3). Los contraceptivos más prevalentes fueron la píldora y el condón. Se asociaron al no uso de anticonceptivos: religión (Pentecostal), número de hijos (menos de 3), no haber usado contraceptivo en la primera relación sexual, no tener pareja y no haber tenido relaciones sexuales durante el mes anterior. El número de hijos y la edad de la mujer fueron los dos primeros niveles de discriminación de los tipos de contraceptivo utilizados. La prevalencia de la anticoncepción es alta, pero se mantiene la concentración en dos métodos: anteriormente, ligadura y píldora, ahora, píldora y condón. Es necesario incorporar nuevos contraceptivos hormonales en el Sistema Único de Salud (SUS), así como promover el uso de métodos de larga duración como el DIU.

Demographic, socioeconomic and lifestyle factors associated with sugar-sweetened beverage intake: a population-based study.

INTRODUCTION: The intake of sugar-sweetened beverages (SSB) varies according to the characteristics of the population. OBJECTIVE: To investigate the SSB intake and demographic, socioeconomic and lifestyle factors associated with its consumption in adolescents, adults, and older adults in São Paulo. METHODS: Data were drawn from the Health Survey of São Paulo, a cross-sectional population-based study including 1,662 individuals aged 12 years or more. SSB were classified into six groups: sugar-sweetened sodas, sweetened coffee and tea, sweetened milk and dairy products, sweetened fruit juice, sweetened fruit drink, and total SSB. The association of each group with demographic, socioeconomic and lifestyle variables was assessed using linear regression models. RESULTS: The mean SSB intake was 668.4 mL in adolescents, 502.6 mL in adults, and 358.2 mL in elderly adults. Sodas and sweetened coffee and tea represented had the greatest contribution to energy intake. SSB consumption was lower among female sex and higher among overweight adolescents, among sufficiently active adults, and among lower household per capita income older adults. Consumption of SSB was high, particularly among adolescents. Public policies are required in order to decrease the consumption of these beverages. CONCLUSION: Age group, sex, household per capita income, and body mass index status were associated with SSB intake.

Health services utilization to control arterial hypertension and diabetes mellitus in the city of São Paulo. / Uso de serviços de saúde para controle da hipertensão arterial e do diabetes mellitus no município de São Paulo.

OBJECTIVE: To describe the prevalence of health services utilization for control of arterial hypertension (AH) and diabetes mellitus (DM) in the city of São Paulo in 2003, 2008 and 2015 and to analyze associated factors to this utilization in 2015. METHODS: Data regarding adults who participated in the Health Surveys conducted in the city of Sao Paulo, ISA-Capital 2003, 2008 and 2015, were analyzed. Prevalences and 95% confidence intervals for the three years were estimated to describe the prevalence of the use of services to control HA and DM. For the year of 2015, prevalences of the same variables were estimated according to sociodemographic, geographic and health characteristics. Multinomial logistic regression was used to estimate AH and DM analysis models. RESULTS: There was a significant increase in the prevalence of people who reported routine health services utilization to control AH and DM in the period 2003-2015. For 2015, an increased routine health services utilization to control AH was observed among elderly and those who reported health insurance. For those who reported DM, an association between health services utilization and low schooling was found. Being elderly reduces the risk of not going to the health services to control AH, while being male and not having a health insurance increase this risk significantly. CONCLUSIONS: to identify how individuals with AH and DM use health services in way to control these diseases is very important to reduce access barriers and, yet, provide guidance in health policies to reduce disparities.

OBJETIVO: Descrever as prevalências do uso de serviços de saúde para controle da hipertensão arterial (HA) e do diabetes mellitus (DM) no município de São Paulo nos anos de 2003, 2008 e 2015 e analisar os fatores associados a esse uso no ano de 2015. MÉTODOS: Foram analisados dados de população adulta provenientes dos inquéritos de saúde no município de São Paulo em 2003, 2008 e 2015. Foram estimadas as prevalências e seus intervalos de confiança de 95% nos 3 anos para descrever as prevalências do uso de serviços de saúde para controle da HA e do DM. Para 2015, foram estimadas as prevalências para as mesmas variáveis segundo características sociodemográficas, geográficas e de saúde. Utilizou-se regressão logística multinomial para estimar modelos de análise para HA e DM. RESULTADOS: Observou-se aumento significativo no percentual de pessoas que referiram ir ao serviço de saúde de rotina por causa da HA e do DM no período 2003 a 2015. Em 2015, maior uso de serviços de saúde de rotina para controle da HA foi observado entre os idosos e as pessoas que referiram possuir plano de saúde. No caso do DM, houve associação entre o uso de serviços e baixa escolaridade. Ser idoso diminui o risco de não ir ao serviço de saúde para o controle da HA, enquanto ser do sexo masculino e não possuir plano de saúde aumentam esse risco significativamente. CONCLUSÕES: Identificar como os indivíduos com HA e DM utilizam os serviços de saúde para controle das doenças é de extrema relevância para reduzir barreiras no acesso e, ainda, orientar políticas de saúde no intuito de reduzir desigualdades.

[Prevalence of common mental disorders and associated factors in urban residents of São Paulo, Brazil]. / Prevalência de transtornos mentais comuns e fatores associados em moradores da área urbana de São Paulo, Brasil.

Studies in developing countries report a steady increase in mental disorders, with major social and economic repercussions. The current study proposes to analyze the prevalence of common mental disorders (CMDs) and associated factors in urban residents of São Paulo, Brazil. Based on data collected in the Health Survey in São Paulo City (ISA-Capital) in 2015, the study identified the presence of CMDs using the Self-Reporting Questionnaire (SRQ-20). The association of CMDs with sociodemographic variables and health conditions was analyzed as relative frequency, corrected by the respective weights resulting from cluster sampling, estimating the prevalence and 95% confidence intervals (95%CI) and assessing the association's significance by the chi-square test, corrected by the F distribution. Prevalence of CMDs was 19.7% (95%CI: 18.2-21.4), higher in women (24.3%); persons 60 years or older (25.3%); followers of the African-Brazilian umbanda or candomblé religions (37.8%); widows/widowers (30.4%); individuals that had never attended school (31.4%); unemployed (28.3%); those with family income up to one minimum wage (28.8%); individuals that reported illness in the previous 15 days (36.9%); those with physical disabilities (21.6%); mental or intellectual disabilities (44.4%); emotional or mental problems (48.9%); headache (33.63%); and individuals with one or more chronic diseases (24.1%). The information in this study reaffirms the relevance of the prevalence of CMDs and their association with the most vulnerable social groups, corroborating the need to implement public measures in mental health.

Estudos realizados nos países em desenvolvimento descrevem um aumento progressivo dos transtornos mentais, com grandes repercussões sociais e econômicas. O presente estudo se propõe a analisar a prevalência dos transtornos mentais comuns (TMC) e seus fatores associados nos moradores da área urbana da cidade de São Paulo, Brasil. A partir dos dados levantados pelo Inquérito de Saúde do Município de São Paulo (ISA-Capital) de 2015, foi identificada a presença de TMC com a utilização do Self-Reporting Questionnaire (SRQ-20). A associação de TMC com as variáveis sociodemográficas e de condições de saúde foi analisada pela frequência relativa, corrigida pelos respectivos pesos decorrentes de uma amostragem de conglomerados, estimando-se a prevalência e intervalos de 95% de confiança (IC95%) em cada situação e avaliando-se a significância da associação pelo qui-quadrado corrigido pela distribuição F. A prevalência de TMC encontrada foi de 19,7% (IC95%: 18,2-21,4), sendo maior nas seguintes categorias: mulheres (24,3%); pessoas com 60 anos ou mais (25,3%); praticantes da umbanda/candomblé (37,8%); viúvos (30,4%); quem nunca frequentou a escola (31,4%); inativos/desempregados (28,3%); e quem possuía renda familiar de até um salário mínimo (28,8%). Em relação às variáveis de condição de saúde, a prevalência de TMC foi maior nos indivíduos que referiram: morbidade nos últimos 15 dias (36,9%); deficiência física (21,6%); deficiência mental ou intelectual (44,4%); problema emocional ou mental (48,9%); cefaleia (33,63%); e nos portadores de uma ou mais doenças crônicas (24,1%). As informações desta pesquisa reafirmam a relevância da prevalência de TMC assim como sua associação com os grupos sociais mais vulneráveis, o que reforça a necessidade da implementação de medidas públicas de saúde mental.

Young women's contraceptive practices: a household survey in the city of São Paulo, Brazil. / Práticas contraceptivas de mulheres jovens: inquérito domiciliar no Município de São Paulo, Brasil.

The last decade has witnessed initiatives to expand access to contraceptives in Brazil. However, the last population-based study on contraception was undertaken in 2006. A household survey in 2015 investigated contraceptive practices in women 15 to 44 years of age living in the city of São Paulo. The current study selected data on young women 15 to 19 years of age. The objectives were to identify the prevalence of contraception, the contraceptives used, sources, and differences in contraceptive practices. The young women are part of a probabilistic study sample. Differences in contraception use were compared by multiple logistic regression analysis. A total of 633 young women were interviewed, of whom 310 (48.5%) were sexually initiated. Of these, 60% reported emergency contraception use at least once in their lives. Emergency contraception use was directly proportional to age and lifetime number of partners. Prevalence of contraception was 81%. The odds of current contraception use were higher among young women residing in the health district of the city with the better social conditions, Catholics, those who reported sexual relations in the previous 30 days, and those with history of an obstetrics and gynaecology visit in the previous year, and inversely proportional to the lifetime number of sex partners. Male condoms and the pill were the most common methods (28.2% and 23%). Most of the women purchased their contraceptives in retail pharmacies (75.2%), and the Brazilian Unified National Health System (SUS) was only a significant source for injectable hormonal contraceptives. Government support for women's sexual and reproductive rights is still insufficient.

Iniciativas para ampliar o acesso a contraceptivos ocorreram no Brasil na última década. No entanto, o último estudo de base populacional sobre anticoncepção foi realizado em 2006. Um inquérito domiciliar investigou a prática contraceptiva de mulheres com 15 a 44 anos, residentes no Município de São Paulo em 2015. Para o presente trabalho, foram selecionados os dados relativos às jovens com idade entre 15 e 19 anos. Foram objetivos: identificar a prevalência da anticoncepção, os contraceptivos adotados, suas fontes de obtenção e os diferenciais no uso da contracepção. As jovens integram a amostra probabilística do estudo. Diferenciais do uso de contracepção foram avaliados por meio de regressão logística múltipla. Foram entrevistadas 633 jovens, das quais, 310 (48,5%) haviam iniciado atividade sexual. Dessas, 60% relataram uso de contracepção de emergência pelo menos uma vez na vida. Esse uso foi diretamente proporcional à idade e ao número de parceiros na vida. A prevalência da anticoncepção foi de 81%. A chance de estar usando contraceptivo foi maior entre as residentes na região de saúde com melhor desenvolvimento social, as católicas, as que tiveram relação sexual nos últimos 30 dias e as que realizaram consulta ginecológica no último ano. Foi inversamente proporcional ao número de parceiros na vida. Preservativo masculino e pílula foram os métodos mais frequentes (28,2% e 23%). A maioria das mulheres comprou o contraceptivo na rede comercial de farmácias (75,2%), o Sistema Único de Saúde (SUS) foi fonte significativa apenas para a obtenção do anticoncepcional hormonal injetável. O apoio do Estado ao exercício dos direitos sexuais e reprodutivos segue insuficiente.

Se entrevistaron a 633 jóvenes, de las cuales 310 (48,5%) habían comenzado su actividad sexual. De éstas, un 60% informaron el uso de métodos anticonceptivos de emergencia por lo menos una vez en la vida. Este uso fue directamente proporcional a la edad y al número de parejas en su vida. La prevalencia de métodos anticonceptivos fue de un 81%. La oportunidad de estar usando algún método anticonceptivo fue mayor entre las residentes en la región de salud con un mejor desarrollo social, las católicas, las que tuvieron relaciones sexuales en los últimos 30 días y las que fueron a una consulta ginecológica durante el último año. Fue inversamente proporcional al número de parejas en su vida. El preservativo masculino y la píldora fueron los métodos más frecuentes (28,2% y 23% respectivamente). La mayoría de las mujeres compró el contraceptivo en la red comercial de farmacias (75,2%), el Sistema Único de Salud (SUS) fue una fuente significativa solamente para la obtención del anticonceptivo hormonal inyectable. El apoyo del Estado al ejercicio de los derechos sexuales y reproductivos sigue siendo insuficiente.

Sampling plan in health surveys, city of São Paulo, Brazil, 2015.

OBJECTIVE: To evaluate the sampling plan of the Health Survey of the City of São Paulo (ISA-Capital 2015) regarding the accuracy of estimates and the conformation of domains of study by the Health Coordinations of the city of São Paulo, Brazil. METHODS: We have described the population, domains of study, and sampling procedures, including stratification, calculation of sample size, and random selection of sample units, of the Health Survey of the City of São Paulo, 2015. The estimates of proportions were analyzed in relation to precision using the coefficient of variation and the design effect. We considered suitable the coefficients below 30% at the regional level and 20% at the city level and the estimates of the design effect below 1.5. We considered suitable the strategy of establishing the Health Coordinations as domains after verifying that, within the coordinations, the estimates of proportions for the age and sex groups had the minimum acceptable precision. The estimated parameters were related to the subjects of use of services, morbidity, and self-assessment of health. RESULTS: A total of 150 census tracts were randomly selected, 30 in each Health Coordination, 5,469 households were randomly selected and visited, and 4,043 interviews were conducted. Of the 115 estimates made for the domains of study, 97.4% presented coefficients of variation below 30%, and 82.6% were below 20%. Of the 24 estimates made for the total of the city, 23 presented coefficient of variation below 20%. More than two-thirds of the estimates of the design effect were below 1.5, which was estimated in the sample size calculation, and the design effect was below 2.0 for 88%. CONCLUSIONS: The ISA-Capital 2015 sample generated estimates at the predicted levels of precision at both the city and regional levels. The decision to establish the regional health coordinations of the city of São Paulo as domains of study was adequate.

[Prevalence of arterial hypertension, diabetes mellitus, and adherence to behavioral measures in the city of São Paulo, Brazil, 2003-2015]. / Prevalência da hipertensão arterial, do diabetes mellitus e da adesão às medidas comportamentais no Município de São Paulo, Brasil, 2003-2015.

The objective was to compare the estimates for prevalence of diabetes, hypertension, and behavioral measures to control these diseases. Data were analyzed for the adult population from Health Surveys in the city of São Paulo, Brazil, in 2003, 2008, and 2015. Prevalence rates and 95% confidence intervals (95%CI) were calculated for the following: hypertension, diabetes, and practices to control these diseases (diet, physical activity, oral medication, insulin, nothing). Estimates were compared by age and sex-adjusted Poisson regression and analyzed according to the 20-59-years and 60-and-older age brackets. The data were presented comparing 2008 to 2003 and 2015 to 2003. Among persons 20 to 59 years of age, there was an increase in the prevalence rates for: hypertension in 2003-2015 (PR = 1.27; 95%CI: 1.03-1.60) and diet for both periods (2003-2008, PR = 2.04; 95%CI: 1.42-2.91; and 2003-2015, PR = 1.51; 95%CI: 1.05-2.15). Among persons 60 years and older: diabetes (PR = 1.29; 95%CI: 1.08-1.56) and oral medication to control diabetes (PR = 1.38; 95%CI: 1.17-1.63), both in 2003-2015; hypertension in 2003-2015 (PR = 1.19; 95%CI:1.05-1.39); and diet and oral medication to control hypertension in 2003-2008 (PR = 1.20; 95%CI: 0.95-1.51 and PR = 1.02; 95%CI: 0.95-1.09, respectively). The results are important for surveillance and monitoring of the target indicators and provide backing for planning health care activities in the city of São Paulo. Linking and aligning effective and integrated interventions is indispensable for reducing and controlling these chronic noncommunicable diseases.

O objetivo foi comparar as estimativas de prevalência de diabetes, hipertensão e as medidas de controle para estas doenças. Foram analisados dados de população adulta provenientes dos Inquéritos de Saúde no Município de São Paulo, Brasil, 2003, 2008 e 2015. Foram estimadas as prevalências e seus intervalos de 95% de confiança (IC95%) para as variáveis: hipertensão, diabetes e as práticas de controle para estas doenças (dieta alimentar, atividade física, medicamento oral, insulina, não faz nada). As estimativas foram comparadas por regressão de Poisson ajustada por sexo e idade, e analisadas segundo os domínios 20-59 e 60 anos e mais. Os dados foram apresentados comparando-se os anos de 2008 em relação a 2003 e 2015 em relação a 2003. Entre as pessoas de 20-59 anos, observou-se aumento nas prevalências de: hipertensão no período 2003-2015 (RP = 1,27; IC95%: 1,03-1,60) e dieta alimentar para ambos os períodos (2003-2008, RP = 2,04; IC95%: 1,42-2,91; e 2003-2015, RP = 1,51; IC95%: 1,05-2,15). Dentre as pessoas com 60 anos e mais: diabetes (RP = 1,29; IC95%: 1,08-1,56) e medicamento oral para controlar a diabetes (RP = 1,38; IC95%: 1,17-1,63), ambos no período 2003-2015; hipertensão no período 2003-2015 (RP = 1,19; IC95%: 1,05-1,39); e dieta alimentar e medicamento oral para controlar a hipertensão no período 2003-2008 (RP = 1,20; IC95%: 0,95-1,51 e RP = 1,02; IC95%: 0,95-1,09, respectivamente). Os resultados são importantes para a vigilância e monitoramento dos indicadores analisados, e fornecem subsídio ao planejamento de ações em saúde no Município de São Paulo. Articular e alinhar ações efetivas e integradas é imprescindível para a redução e controle dessas doenças.

2015 Health Survey of São Paulo with Focus in Nutrition: Rationale, Design, and Procedures.

This paper describes the design, sampling methods, and data collection procedures, with particular focus on dietary data, used for the 2015 Health Survey of São Paulo (Inquérito de Saúde de São Paulo, 2015 ISA-Capital) with Focus in Nutrition Study (2015 ISA-Nutrition). The ISA is a household cross-sectional, population-based survey that uses complex, stratified, multistage sampling to create a representative sample of residents from urban São Paulo, Brazil. The 2015 ISA-Nutrition comprised a sub-sample of the 2015 ISA-Capital and intended to include 300 adolescents (aged 12 to 19 years), 300 adults (aged 20 to 59 years), and 300 older adults (aged ≥60 years). From February 2015 to February 2016, 1737 individuals answered the first 24-h dietary recall (24HR), and 901 individuals consented to have their blood sample collected, to undergo anthropometric and blood pressure assessment, and to answer the second 24HR. The 2015 ISA-Nutrition aims to evaluate lifestyle-related modifiable factors in São Paulo's residents, as well as their association with biochemical and genetic markers, and environmental aspects related to cardiometabolic risk factors. This paper concludes that 2015 ISA-Nutrition may provide valuable insights into the cardiometabolic risk factors in a big city in an upper middle-income country and contribute to the formulation of health and nutritional policies.

Access to Street Markets and Consumption of Fruits and Vegetables by Adolescents Living in São Paulo, Brazil.

Food environment and income act as determinants of diet, and consequently, of the consumption of fruits and vegetables. The objective of this study is to investigate the association between fruit and vegetable consumption, income, and street market density in adolescents living in São Paulo, Brazil. Data from 521 adolescents (12 to 19 years) participating in the 2015 Health Survey of São Paulo were used. Buffers (500, 1000, and 1500 m) were drawn around the households and the street markets were counted in each zone. Multilevel logistic regression models were used to evaluate the association between fruit and vegetable consumption, income, and street market density. The main results showed that the presence of a street market in the zone closest to the households (500 m) was associated with higher consumption of fruits and vegetables (OR: 1.73; CI 95% 1.01-3.00). Higher family income was associated with a higher consumption of fruits and vegetables for models of 500 m buffer (OR: 2.56; CI 95% 1.47-4.45), 1000 m (OR: 2.30; CI 95% 1.33-3.96), and 1500 m (OR: 2.32; CI 95% 1.35-4.00). These results support the implementation of public policies that jointly consider income and the availability of street markets or healthy food environments.

[Structural and functional aspects of social support for the elderly in the city of São Paulo, Brazil]. / Aspectos estruturais e funcionais do apoio social de idosos do Município de São Paulo, Brasil.

This study aimed to describe the distribution of social support networks for the elderly in the City of São Paulo, Brazil, based on socioeconomic and demographic characteristics. A probability sample of 1,568 elderly persons (> 60 years) was studied (SABE query), focusing on structural and functional dimensions of social networks. Univariate and multiple logistic regression models were used to analyze the data. The best conditions in social networks were in the lowest income levels and the worst among older and unmarried people. For women, unmarried marital status was significantly associated with lower schooling. Cohabiting had the strongest influence on the functional dimension, while "living alone" significantly decreased the odds of social exchange. Multiple logistic regression by gender suggested that age, marital status, per capita income, and schooling were associated with social networks among elderly people. However, these relationships were expressed unevenly between the genders and depending on the socio-demographic characteristics of the different dimensions of the social support network.

Adolescent pregnancy and transition to adulthood in young users of the SUS.

OBJECTIVE: The objective of this study is to contextualize adolescent pregnancy from milestones associated with the process of transition from youth to adulthood. METHODS: This is a cross-sectional study conducted with 200 adolescents, users of the Brazilian Unified Health System. The sample size for the estimation of proportions has been calculated assuming a population ratio of 0.50 and 95% confidence level. The dependent variables - planned pregnancy, living with a partner, and having left the parents' house - have been considered as markers of transition from dependence to independence, from youth to adulthood. In the analysis of the associated factors, we have used the Poisson model with robust variance. RESULTS: Average age was 17.3 years, and most adolescents lived with a partner; approximately half of the adolescents got pregnant from their first partner and the average age of first sexual intercourse was 14.6 years. Only 19% of the adolescents were studying and most dropped out of school before the beginning of the pregnancy. In the bivariate and multiple analysis, we could see that the relationship with a partner for more than two years was associated with the three dependent variables. CONCLUSIONS: The path of transition to adulthood has been the establishment of a link with a partner and consequent pregnancy, suggesting a clear pattern of male guardianship. The changing role of women in society observed in recent decades, which means choosing a professional career, defining the number of children, and choosing their partner(s), has not reached these young persons. OBJETIVO: Contextualizar a gestação em adolescentes a partir de marcos associados ao processo de transição da juventude para a vida adulta. MÉTODOS: Estudo transversal realizado com 200 adolescentes usuárias do Sistema Único de Saúde. O tamanho da amostra para a estimação de proporções foi calculado considerando uma proporção populacional de 0,50, e nível de confiança de 95%. As variáveis dependentes - gestação planejada, morar com o parceiro e ter saído da casa dos pais - foram consideradas marcadores da transição da dependência para a independência, da juventude para a vida adulta. Na análise dos fatores associados, utilizou-se o modelo de Poisson com variância robusta. RESULTADOS: A idade média foi 17,3 anos, a maioria coabitava com o companheiro; aproximadamente metade engravidou do primeiro parceiro e a idade média da primeira relação sexual foi 14,6 anos. Apenas 19% das jovens estudavam e o abandono escolar foi, na maior parte, anterior ao início da gestação. Nas análises bivariadas e na análise múltipla, observou-se que relacionar-se com o parceiro há mais de dois anos se associou às três variáveis dependentes. CONCLUSÕES: O caminho de transição para a vida adulta foi o estabelecimento de um vínculo com um parceiro e consequente maternidade, sugerindo padrão claro de tutela masculina. A mudança do papel da mulher na sociedade observada nos últimas décadas, que implica optar por uma carreira profissional, definir número de filhos e escolher o(s) parceiro(s),não chegou a parcela dessas jovens.

[Healthy lifestyle in São Paulo, Brazil]. / Estilo de vida saudável em São Paulo, Brasil.

The objective was to analyze adolescent, adult, and elderly lifestyles in the city of São Paulo, Brazil, according to demographic and socioeconomic variables. A cross-sectional, population-based study was performed with data from the Health Survey in São Paulo City (ISA-Capital 2008) database. Lifestyle was defined on the basis of physical activity, diet, smoking, and alcohol abuse and addiction, according to the respective guidelines. Prevalence of healthy lifestyle was 36.9% in the elderly, 15.4% in adults, and 9.8% in adolescents, and was higher in females in the elderly and adults. Among individuals with unhealthy lifestyle, 51.5% of the elderly, 32.2% of adults, and 57.9% of adolescents failed to reach the guidelines for adequate diet. Prevalence of healthy lifestyle was highest among the elderly, followed by adults and adolescents. Food consumption was the main factor associated with unhealthy lifestyle, demonstrating the importance of interventions to promote healthy lifestyle, especially adequate diet.

Validation of self-reported diabetes in a representative sample of São Paulo city.

OBJECTIVE To validate the self-reported diabetes mellitus in adults and older adults living in the city of São Paulo, Brazil. METHODS We have used data of 569 subjects (284 adults and 285 older adults), participants of the population-based cross-sectional study Inquérito de Saúde do Município de São Paulo (Health Survey of São Paulo). Fasting glucose ≥ 7.0 mmol/L (126 mg/dL) and/or use of drugs (oral hypoglycemic and/or insulin) defined the diagnosis of diabetes mellitus. We have validated the self-reported diabetes mellitus by calculating the sensitivity, specificity, positive predictive values, and negative predictive values. We have used Poisson regression with robust variance to verify the factors associated with the sensitivity of the self-reported datum. For all analyses, we have considered the sample design of the study. RESULTS The sensitivity of self-reported diabetes mellitus was 63.8% (95%CI 49.2-76.3), specificity was 99.7% (95%CI 99.1-99.9), positive predictive value was 95.5% (95%CI 84.4-98.8), and negative predictive value was 96.9% (95%CI 94.9-98.2). The correct reporting of diabetes mellitus was more prevalent among older adults (PR = 2.0; 95%CI 1.2-3.5) than among adults. CONCLUSIONS The use of the datum of self-reported diabetes mellitus is valid, especially among older adults living in the city of São Paulo. The results highlight the need to track diabetes mellitus in asymptomatic subjects who have one or more risk factors for it, mainly in the adult population of this city.

National Survey on Access, Use and Promotion of Rational Use of Medicines: methods.

The Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos -Serviços (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services) aimed to characterize the organization of pharmaceutical services in the Primary Health Care of the Brazilian Unified Health System (SUS). PNAUM - Services is a cross-sectional and evaluative study, with planned sample of 600 cities, held between 2014 and 2015, composed of a remote phase, with telephone interviews with health managers. Of these 600 cities, 300 were selected for a survey on health services. We selected the 27 capitals, the 0.5% largest cities of each region, and the remaining cities were drawn. The estimate of the representative national sample size considered three levels: cities, medicine dispensing services, and patients. The interviews were carried out with a structured questionnaire specific for: municipal secretaries of health, professionals responsible for pharmaceutical services in the city, professionals responsible for the dispensing of medicines, physicians, and patients. The secondary data were obtained in official databases, in the latest update date. PNAUM - Services was the first nationwide research aimed at the assessment and acquisition of national and regional indicators on access to medicines, as well as use and rational use, from the perspective of various social subjects.
