Population Prevalence of Trachoma in Nine Rural Non-Indigenous Evaluation Units of Brazil. Ophthalmic Epidemiol 2023; 30:561-570. [PMID: 34711133 PMCID: PMC10581672 DOI: 10.1080/09286586.2021.1941127] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 05/20/2021] [Accepted: 06/04/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE To assess the contemporary prevalence of trachoma in Brazil's non-indigenous population, surveys of those thought to be at greatest risk of disease were conducted. METHODS Rural census tracts of non-indigenous population from nine mesoregions were selected to compose the survey evaluation units (EUs) by considering previously endemic municipalities at greatest risk of trachoma. In each of the nine EUs, we conducted a population-based prevalence survey. Every resident of selected households aged ≥ 1 year was examined for trachomatous inflammation - follicular (TF) and trachomatous trichiasis (TT). Additionally, data were collected on household-level access to water, sanitation, hygiene (WASH) and education. RESULTS A total of 27,962 individuals were examined across nine EUs. The age-adjusted TF prevalence in 1-9-year-olds was <5% in each EU. The age- and gender-adjusted prevalence of TT unknown to the health system in ≥15-year-olds was <0.2% in eight EUs; in one EU, it was 0.22%. The median number of households surveyed per EU with access to an improved drinking water source within a 30-minute roundtrip of the house was 66%. School attendance was >99% of surveyed children. CONCLUSIONS The prevalence of TF was well below the target for elimination as a public health problem in all EUs. Because EUs surveyed were selected to represent the highest-risk non-indigenous areas of the country, TF prevalence is unlikely to be ≥5% in non-indigenous populations elsewhere. In one EU, the prevalence of TT was above the target threshold for elimination. Further investigation and possibly improvement in TT surgical provision are required in that EU.

Papanicolaou test in Brazil: analysis of the National Health Survey of 2013 and 2019. Rev Saude Publica 2023; 57:55. [PMID: 37878841 PMCID: PMC10519687 DOI: 10.11606/s1518-8787.2023057004798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 09/26/2022] [Indexed: 10/27/2023] Open
Abstract
OBJECTIVES To compare the coverage of cervical cancer screening in Brazil in 2013 and 2019, investigating the factors associated with having the test performed and the reasons given for not doing it. Additionally, a comparison is made concerning the time taken to receive the test result in SUS (Sistema Único de Saúde) and in the private health services. METHODS Using data from the National Health Survey (Pesquisa Nacional de Saúde - PNS), prevalence rates and corresponding confidence intervals were calculated to determine the frequency of recent cervical cancer screenings among women aged between 25 and 64 years old in Brazil, for both 2013 and 2019. Poisson regression models were employed to compare the prevalence of the outcome according to sociodemographic characteristics. The reasons for not having the test and the time between performing and receiving the result were also analyzed. RESULTS The findings revealed an increase in the coverage of preventive cervical cancer exams in Brazil from 78.7% in 2013 to 81.3% in 2019. Additionally, there was a decline in the proportion of women who had never undergone the exam, from 9.7% to 6.1%. Prevalence of test uptake was higher among white women, those with higher levels of education and income, and those residing in the South and Southeast regions of the country. The most commonly cited reasons for not taking the test were the impression it was unnecessary (45% in both 2013 and 2019) and never having been asked to undergo the test (20.6% in 2013 and 14.8% in 2019). CONCLUSIONS Despite the high coverage of screening achieved in the country, there is great inequality in access to the test, and a non-negligible number of women are at greater risk of dying from a preventable disease. Efforts must be made to structure an organized screening program that identifies and captures the most vulnerable women.

Sexual behavior and self-declaration of sexual orientation among people 18-64 years in Brazil: results from the Knowledge, Attitudes, and Practices survey, 2013 and the National Health Survey, 2019. BMC Public Health 2023; 23:1476. [PMID: 37533022 PMCID: PMC10399013 DOI: 10.1186/s12889-023-16420-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Accepted: 07/29/2023] [Indexed: 08/04/2023] Open
Abstract
BACKGROUND Population surveys involving the monitoring of high-risk sexual behavior have been recognized as important public health tools to control the HIV epidemic and other sexually transmitted infections (STIs). METHODS Using data from the Knowledge, Attitudes, and Practices survey (PCAP-2013) and from the National Health Survey (PNS-2019), indicators of sexual behavior were compared according to sociodemographic characteristics among individuals aged 18-64 years, including size (%) estimates of men who have sex with men (MSM) and women who have sex with women (WSW). Specifically, the PNS-2019 prevalence estimates of homosexual, bisexual, heterosexual males and females were compared with those from the PCAP-2013. To compare PCAP and PNS proportional distributions, the Pearson's chi-square test, adjusted by the Rao-Scott's correction, was applied. RESULTS Size (%) estimates of MSM and WSW obtained by direct questions from the PCAP-2013, showed higher homosexuality prevalence estimates than those resulting from the PNS-2019 self-declared sexual orientation. Significant differences were found between the MSM proportions according to the PCAP-2013 (3.7%; 95% CI 3.1-4.4%) and to the PNS-2019 (2.2%; 95% CI 1.9-2.5), and between the WSW proportions (4.6%; 95% CI 4.0-5.4%) and (2.1%; 95% CI 1.8-2.4), respectively. Results from both surveys showed MSM and WSW prevalence estimates increase with educational level, decrease with age, and is larger among people who do not live with partner, live in urban areas and in state capitals. Regarding condom use at last sexual intercourse, no differences between the PCAP-2013 and the PNS-2019 estimates were found at the national level, but significant improvements were found for MSM, people aged 18-24 and 25-34 years, and individuals not living with a partner. CONCLUSIONS The underestimation of MSM and WSW prevalence by self-declared sexual orientation suggests that sexual minorities face many difficulties related to disclosing their sexuality and reinforces the importance of developing public health interventions for changing population attitudes and promoting sexual orientation disclosure. Moreover, the low use of condoms in both surveys (PCAP-2013 and PNS-2019) carried out 6 years apart highlights the need of public policies to expand prevention strategies for HIV infection and other STIs.

[PMID: 37436311 DOI: 10.1590/1413-81232023287.15922022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 11/15/2022] [Indexed: 07/13/2023] Open
Abstract
Differences in the profiles of illness and lifestyles among agricultural and non-agricultural workers were investigated using data from the National Health Survey (Brazilian acronym PNS) of 2013 and 2019. The prevalence and 95% CIs were calculated for the following variables: self-reported morbidities, poor self-rated health, limitations of usual activities, number of NCD, major or minor depression and lifestyles. The Poisson model was used to calculate crude and adjusted prevalence ratios, by gender and age. The sample weights and the conglomerate effect in 2013 and 2019 were considered in the analyses. A total of 33,215 non-agricultural workers and 3,797 agricultural workers were evaluated in 2013, whereas 47,849 non-agricultural workers and 4,751 agricultural workers were assessed in 2019. Agricultural workers are more susceptible to poor self-rated health, chronic back problems, excessive physical activity at work, smoking and lower consumption of vegetables and fruit. On the other hand, non-agricultural workers revealed a higher prevalence of asthma/bronchitis, depression and diabetes mellitus and greater consumption of candies and soft drinks. Differentiated NCD prevention and treatment actions for both groups of workers need to be prioritized.

Assessment of the Accuracy, Usability and Acceptability of a Rapid Test for the Simultaneous Diagnosis of Syphilis and HIV Infection in a Real-Life Scenario in the Amazon Region, Brazil. Diagnostics (Basel) 2023; 13:diagnostics13040810. [PMID: 36832298 PMCID: PMC9955085 DOI: 10.3390/diagnostics13040810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/18/2023] [Accepted: 01/20/2023] [Indexed: 02/23/2023] Open
Abstract
We field-assessed the accuracy, acceptability, and feasibility of the SD BIOLINE HIV/Syphilis Duo rapid diagnostic test in three groups: pregnant women, female sex workers (FSW), and men who have sex with men (MSM). Venous blood samples collected in the field were compared with the respective gold standard methods: SD BIOLINE HIV/Syphilis Duo Treponemal Test versus FTA-abs (Wama brand) treponemal laboratory test for syphilis, and SD BIOLINE HIV/Syphilis Duo Test versus the fourth generation Genscreen Ultra HIV Ag-Ag (Bio-Rad brand) laboratory test for HIV. From a total of 529 participants, 397 (75.1%) were pregnant women, 76 (14.3%) FSW and 56 (10.6%) MSM. Sensitivity and specificity parameters of HIV were 100.0% (95% CI: 82.35-100.0%) and 100.0% (95% CI: 99.28-100.0%), respectively. Sensitivity and specificity parameters found for TP antibody detection were 95.00% (95% CI: 87.69-98.62%) and 100.0% (95% CI: 98.18-100.0%), respectively. The SD BIOLINE HIV/Syphilis Duo Test showed high acceptability among participants (85.87%) and health professionals (85.51%), as well as easy usability by professionals (91.06%). The usability of the SD BIOLINE HIV/Syphilis Duo Test kit would not be a barrier to accessing rapid testing, if the product were incorporated into the list of health service supplies.

Abstract
OBJECTIVE To assess factors associated with the habit of drinking and driving and estimating the variations in the prevalence of this behavior in 2013 and 2019, considering information from the two editions of the Pesquisa Nacional de Saúde (PNS - National Survey of Health). METHODS PNS is a nationwide cross-sectional home-based study. In 2013 and 2019, 60,202 and 85,854 individuals were interviewed, respectively. To assess the association between the indicator "drinking and driving" and the study variables, crude and adjusted odds ratios (ORs) were estimated using logistic regression models. To compare the prevalence between the studied years, a Pearson's chi-squared test adjusted by the Rao-Scott correction (which considers the effect of the sampling plan) and converted into an F statistic, tested at a 5% significance level, was used. RESULTS The prevalence of drinking and driving was higher among men in 2013 (27.4%; 95%CI 25.6-29.3%) and 2019 (20.5%; 95%CI 19.4-21.7%) than among women (11.9%; 95%CI 9.9-14.2% and 7.2%; 95%CI 6.7-9.0%, respectively). Inidviduals aged 30 to 39, who lived without a partner, in rural areas, and were motorcycle drivers had significantly higher estimates. Men with higher income had higher prevalence of drinking and driving. From 2013 to 2019, the act of drinking and driving significantly decreased. Regarding traffic accidents, ORs were significant (p < 0.01) in the studied years for both men and women. DISCUSSION Results show the need to continue policies to monitor blood alcohol level and traffic education, with specific actions directed to rural areas and motorcycle drivers.

Abstract
Female sex workers (FSW) suffer stigma and discrimination that negatively impact their physical and mental health and affect access to health care services. This paper aims to describe selected health indicators among FSW in 12 Brazilian cities in 2016. Brazilian cross-sectional Biological Behavioral Surveillance Survey was conducted in 2016 among 4328 FSW recruited by respondent-driven sampling. The sample weighing was inversely proportional to participant's network sizes and the seeds were excluded from the analysis. Health indicators were estimated with 95% confidence interval and included indicators of health status, symptoms of depression, antenatal care, pap smear coverage, signs and symptoms of sexually transmitted infection, contraception and regular condom use, number of births and children alive per women, human immunodeficiency virus and syphilis testing, usual source of care, and perception of discrimination. Most participants self-rated their health as very good/good (65.8%) and 27.7% were positively screened for major depressive disorder episode on Patient Health Questionnaire-2. Antenatal coverage was 85.8% and 62.3% of FSW had access to pap smear exam in the past 3 years. A total of 67.0% of FSW were using some contraceptive method at the time of the study. Male condom was the most common method (37.1%), followed by oral pill (28.9%). A total of 22.5% FSW had never been tested for HIV and the main reasons were "not feeling at risk" (40.4%) and "being afraid or ashamed" (34.0%). The vast majority of FSW used Brazilian National Health System as their usual source of health care (90.2%). Approximately one-fifth of the participants felt discriminated against or were treated worse for being FSW (21.4%) and only 24.3% disclose their sex work status in health services. The vulnerability of FSW is expressed in all health indicators. Indicators of health status, antenatal care, pap smear coverage, and contraception were worse than in the Brazilian population, and point out to the importance of increase FSW's access to health care services. Also, stigma and discrimination emerged as an important barrier to FSW's health care in all dimensions and need to be struggled.

Abstract
Our objective is to describe the differences in the sampling plans of the two editions of the Brazilian National Health Survey (PNS 2013 and 2019) and to evaluate how the changes affected the coefficient of variation (CV) and the design effect (Deff) of some estimated indicators. Variables from different parts of the questionnaire were analyzed to cover proportions with different magnitudes. The prevalence of obesity was included in the analysis since anthropometry measurement in the 2019 survey was performed in a subsample. The value of the point estimate, CV, and the Deff were calculated for each indicator, considering the stratification of the primary sampling units, the weighting of the sampling units, and the clustering effect. The CV and the Deff were lower in the 2019 estimates for most indicators. Concerning the questionnaire indicators of all household members, the Deffs were high and reached values greater than 18 for having a health insurance plan. Regarding the indicators of the individual questionnaire, for the prevalence of obesity, the Deff ranged from 2.7 to 4.2, in 2013, and from 2.7 to 10.2, in 2019. The prevalence of hypertension and diabetes per Federative Unit had a higher CV and lower Deff. Expanding the sample size to meet the diverse health objectives and the high Deff are significant challenges for developing probabilistic household-based national survey. New probabilistic sampling strategies should be considered to reduce costs and clustering effects.

Abstract
We aimed to assess the factors associated with frequent sadness and nervousness in Brazilian adolescents, during the Covid-19 pandemic, in 9470 adolescents (aged 12-17 years), interviewed from June 27 to September 17, 2020. Prevalences and prevalence ratios were estimated according to socio-demographic variables and factors related to family, school, friends, and health. Brazilian adolescents often felt sad (32.4%) and nervous (48.7%). Higher prevalences of these feelings were related to: being female; aged 15-17 year; from families with financial difficulties; having learned little or nothing with remote education; missing friends; having few friends; family disagreements; having regular/bad health before the pandemic; and worsened health and sleep during the pandemic. Higher prevalence of nervousness was also found in adolescents who worked before the pandemic and those who reported lack of concentration and not knowing if they had COVID-19. Sadness and nervousness in Brazilian adolescents is high and the need for action by the government, schools, health services, and parents to mitigate the impact of the pandemic on the physical and mental health of adolescents. Special attention must be paid to adolescents with previous health problems and those belonging to the most socially vulnerable population.

Abstract
The study aimed to describe knowledge and risk practices related to HIV infection in three Brazilian cities in the general population, men 15 to 24 years of age living without a partner, and men that reported sex with other men (MSM) at least once in life. This was a cross-sectional household-based study with three-stage cluster sampling (census tracts, households, individuals) stratified by sex, age group (15-24; 25-34; 35-44; 45-59), and conjugal status in the individual selection. We estimated the proportions and 95% confidence intervals (95%CI) of indicators of knowledge, HIV testing, sexual behavior, and self-rated risk. We analyzed 5,764 individuals in Campo Grande, 3,745 in Curitiba, and 3,900 in Florianópolis. Low levels of knowledge were found for preventive methods, especially PrEP. Unprotected sex practices were frequent in the three municipalities. Lifetime HIV test rates were 57.2% (95%CI: 55.1-59.2) in Curitiba, 64.3% (95%CI: 62.7-66.0) in Campo Grande, and 65.9% (95%CI: 64.0-67.7) in Florianópolis. Among men 15-24 years of age, the proportions of stimulant drug use and unprotected sexual practices were higher than in the other age groups. Lifetime HIV test rates exceeded 80% in MSM. More than 30% of MSM were receptive partners in anal sex without condoms, and fewer than 5% assessed their risk as high. More effective communication strategies are needed on prevention of HIV infection, including increased knowledge that could motivate safer sexual practices.

Abstract
OBJECTIVE To estimate the prevalence of chronic kidney disease (CKD) in the adult Brazilian population and to describe its characteristics, according to the National Health Survey (PNS) 2013-2019. METHODS Descriptive cross-sectional study, with adults participating in the PNS, based on self-reported medical diagnosis of CKD. Prevalence of CKD and their respective 95% confidence intervals (95%CI) were estimated for Brazil. RESULTS In 2013, 60,202 individuals were analyzed, and in 2019, 85,854. The prevalence of self-reported diagnosis of CKD in both editions was 1.4% and increased with increasing age. In 2019, the prevalence of self-reported CKD was 3.3% (95%CI 2.9;3.7) in hypertensive individuals, 4.1% (95%CI 3.4;5.0) among diabetics, and 3.3% (95%CI 2.8;3.9) in those reporting hypercholesterolemia. CONCLUSION The prevalence of CKD in Brazil remained stable in the period but reinforces the need for expansion of diagnosis and strengthening of primary care in the Brazilian National Health System (SUS).

Abstract
O objetivo do estudo foi descrever o conhecimento e práticas de risco à infecção pelo HIV na amostra total de cada município, entre homens de 15 a 24 anos que vivem sem companheiro(a), e homens que fizeram sexo com homems (HSH) pelo menos uma vez na vida em três cidades brasileiras. Foi realizado estudo de corte transversal de base domiciliar com amostragem por conglomerados em três estágios (setores censitários, domicílios, indivíduos), com estratificação por sexo, faixa etária (15-24; 25-34; 35-44; 45-59) e vive com companheiro(a) na seleção do indivíduo. Estimaram-se proporções e intervalos de 95% de confiança (IC95%) de indicadores de conhecimento, testagem do HIV, comportamento sexual e autoavaliação do risco. Foram analisados 5.764 indivíduos em Campo Grande, 3.745 em Curitiba e 3.900 em Florianópolis. Baixo nível de conhecimento foi encontrado para os métodos de prevenção, sobretudo para profilaxia pré-exposição (PrEP). Práticas de sexo desprotegido foram frequentes nos três municípios. As proporções de teste de HIV na vida foram 57,2% (IC95%: 55,1-59,2) em Curitiba, 64,3% (IC95%: 62,7-66,0) em Campo Grande, e 65,9% (IC95%: 64,0-67,7) em Florianópolis. Entre homens de 15-24 anos, proporções de uso de drogas estimulantes e práticas sexuais desprotegidas foram mais altas que nos demais grupos etários. Entre os HSH, as proporções de teste de HIV na vida foram superiores a 80%. Mais de 30% foram parceiros receptivos no sexo anal sem uso de preservativo, e menos de 5% avaliam seu risco como alto. É preciso adotar estratégias de comunicação mais eficazes sobre a prevenção da infecção do HIV, incluindo a ampliação de conhecimentos que poderiam motivar práticas sexuais mais seguras.

Abstract
INTRODUCTION HIV incidence estimates are essential to monitor the progress of prevention
and control interventions. METHODS Data collected by Brazilian surveillance systems were used to derive HIV
incidence estimates by age group (15-24; 25+) and sex from 1986 to 2018.
This study used a back-calculation method based on the first CD4 count among
treatment-naïve cases. Incidence estimates for the population aged 15 years
or over were compared to Global Burden of Disease Study (GBD) estimates from
2000 to 2018. RESULTS Among young men (15-24 years), HIV incidence increased from 6,400 (95% CI:
4,900-8,400), in 2000, to 12,800 (95% CI: 10,800-15,900), in 2015, reaching
incidence rates higher than 70/100,000 inhabitants and an annual growth rate
of 3.7%. Among young women, HIV incidence decreased from 5,000 (95% CI:
4,200-6,100) to 3,200 (95% CI: 3,000-3,700). Men aged ≥25 years and both
female groups showed significant annual decreases in incidence rates from
2000 to 2018. In 2018, the estimated number of new infections was 48,500
(95% CI: 45300-57500), 34,800 (95% CI: 32800-41500) men, 13,600 (95% CI:
12,500-16,000) women. Improvements in the time from infection to diagnosis
and in the proportion of cases receiving antiretroviral therapy immediately
after diagnosis were found for all groups. Comparison with GBD estimates
shows similar rates for men with overlapping confidence intervals. Among
women, differences are higher mainly in more recent years. CONCLUSIONS The results indicate that efforts to control the HIV epidemic are having an
impact. However, there is an urgent need to address the vulnerability of
young men.

Healthy lifestyle and recommendations in health care among hypertensive and diabetic patients in Brazil, 2019. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2021; 24:e210017. [PMID: 34910071 DOI: 10.1590/1980-549720210017.supl.2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 08/30/2021] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE To estimate prevalence of healthy behaviors among individuals aged 30 years or more, diagnosed with arterial hypertension and diabetes mellitus, using information from the National Health Survey, 2019. METHODS Cross-sectional study with cluster sampling and simple random sampling in three stages. Individuals were aggregated according the following conditions: having arterial hypertension; arterial hypertension only; diabetes mellitus; diabetes mellitus only; arterial hypertension and diabetes mellitus only; without chronic non-communicable diseases. Poisson regression models and crude and adjusted prevalence ratios for sex, age group, and schooling were used. The proportion of recommendations received by patients with arterial hypertension and diabetes mellitus was estimated by type of care (public/private). RESULTS A total of 69,285 individuals aged 30 years or more was analyzed. Compared to individuals without non-communicable diseases, prevalence of consumption of fruits and vegetables ≥5 days a week was significantly higher among individuals with arterial hypertension (39.9% - 95%CI 38.8-41.0) and those with diabetes mellitus (42.8% - 95%CI 40.7-44.9). However, estimates of not having consumed ultra-processed food were low, 19.7% (95%CI 18.9-20.6) and 21.9% (95%CI 20,3-23.5), respectively. Prevalence of not smoking reached values close to 90% and significant prevalence ratios, whereas the practice of physical activity had levels below 30% and non-significant prevalence ratios. The proportion of healthy eating recommendations reached 90%, but it was close to 70% for not smoking. CONCLUSIONS It is necessary to encourage the practice of healthy lifestyles and provide information about the benefits of physical activity and the harmful effects of unhealthy eating for well-being and aging with quality.

Increasing trends in obesity prevalence from 2013 to 2019 and associated factors in Brazil. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2021; 24:e210009. [PMID: 34910063 DOI: 10.1590/1980-549720210009.supl.2] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 08/26/2021] [Indexed: 12/26/2022] Open
Abstract
OBJECTIVE To investigate the variation of anthropometric indicators from 2013 to 2019 and the factors associated with obesity in Brazil, using information from the National Health Survey. METHODS Cross-sectional study with cluster sampling and simple random sampling in the three stages. Measurements of weight and height among participants in 2013 (n=59,592) and in 2019 (n=6,672) were used. Differences in obesity prevalence were tested by Student's t test for independent samples. To identify the sociodemographic factors and health problems associated with obesity, we used Poisson regression models with robust variance and crude and age-adjusted prevalence ratios to test the associations. RESULTS From 2013 to 2019, prevalence of obesity increased significantly, from 20.8 to 25.9%. Among men, the greatest increases were found in the 40-59 age group (9.1%) and in the median income category (8.3%). Among women, the greatest rises were found among those with low education (8.7%) and non-white ones (6.0%). For both males and females, factors associated with obesity were age, to live with a partner, level of instruction directly associated among men, and inversely associated among women. In 2019, for males, the crude and adjusted prevalence ratios were significant for high cholesterol, high blood pressure and at least one chronic non-communicable disease and, for females, for poor self-rated health, high blood pressure, diabetes, and at least one chronic non-communicable. CONCLUSION It is necessary to implement intersectoral policies to promote changes in eating habits and encourage the practice of physical activity, taking into account economic, social, cultural, and environmental aspects.

Abstract
In Brazil, the growth of agribusiness to the detriment of family agriculture occurred while concealing social, environmental and human health damages. The objective was to compare living and working conditions and access to health services between agricultural and non-agricultural workers. Data from the National Health Survey (PNS) on living and working conditions, sociodemographic, economic characteristics, and access to health services from a representative sample of the employed Brazilian population were adopted. Pearson's chi-square test was used, with a significance level of 0.05, taking the complex sampling design into consideration. Agricultural workers suffered from worse living conditions, lower purchasing power, greater exposure to solar radiation and chemical agents, and a higher frequency and severity of occupational accidents compared to non-agricultural workers. The agricultural population had greater coverage of the Family Health Service and sought medical care from the Unified Health System (SUS) to treat diseases, while the non-agricultural workers sought private medical care for preventive actions. The differences found between these workers imply different patterns of illness and define specific health needs.

Abstract
OBJECTIVE To investigate differences in sexual, reproductive health and health status indicators of female sex workers in 12 Brazilian cities. METHODS Cross-sectional study of biological and behavioral surveillance survey with a minimum sample of 350 female sex workers per city, recruited by respondent driven sampling, in 2016. Complex sample design was considered in the data analysis. Indicators and 95% confidence intervals related to sexual and reproductive health, and health status were described separately by city and for the total sample. RESULTS The total sample consisted of 4,328 female sex workers. The coverage of Pap smear exam, human immunodeficiency virus and syphilis tests and antenatal care indicators varied by 20 percentages points or more. Pap smear exam coverage ranged from 53.4% in Recife to 73.0% in Porto Alegre. The highest percentage of female sex workers who had never been tested for human immunodeficiency virus and syphilis was in Fortaleza (36.8 and 63.8%, respectively). Antenatal coverage ranged from 61.1% in Salvador to 99.0% in Curitiba. In five cities, the proportion of female sex workers who disclosed their sex work status in health services was over 20.0%. CONCLUSION The differences between the indicators in the 12 cities followed the Brazilian population profile, with more vulnerable sex workers in the North and Northeast regions. The results show that it is essential to consider the barriers to accessing health, such as stigma and discrimination, which restrict the addressing of female sex workers specific needs.

Abstract
OBJECTIVE This article aims to characterize the heavy drinking behavior in the Brazilian population, using data from the two editions of the "National Health Survey" (PNS), 2013 and 2019. METHODS The sample sizes in 2013 and 2019 were 60,202 and 88,943 individuals aged 18 years or older, respectively. The prevalence of the habit of heavy drinking (defined as 8 or more doses per week for women, and 15 or more doses for men) was estimated, and the confidence intervals were defined by sex, age group, schooling, skin color/race, marital status and household status (urban/rural). Poisson regression models were used to compare prevalence rates. RESULTS 6.1% of Brazilians were heavy drinkers in 2013, and 7.3% in 2019. In the two editions of the PNS there was a gradient of reduction in heavy drinking throughout life, being the highest prevalence among young adults, men, with low schooling, single and living in the urban area. CONCLUSIONS The high prevalence rates expose the need to consider the habit of heavy drinking as a risk factor for the health of the Brazilian population, and the urgency to adopt strategies to reduce it.

Changes in the pattern of health services use in Brazil between 2013 and 2019. CIENCIA & SAUDE COLETIVA 2021; 26:2515-2528. [PMID: 34133631 DOI: 10.1590/1413-81232021266.1.43482020] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 12/01/2020] [Indexed: 11/22/2022] Open
Abstract
This study aimed to investigate changes in the health service use pattern based on information from the 2013 and 2019 National Health Surveys (PNS). The two outcomes, "Seeking health-related care in the past two weeks" and "Medical visit in the last twelve months", were analyzed according to socioeconomic, geographic and health conditions characteristics. Multivariate Poisson regression models were used to investigate the factors associated with seeking care due to a health problem or prevention. The prevalence of chronic diseases increased from 15.0% to 22.5% between 2013 and 2019. The proportion of seeking care increased from 15.3 to 18.6%, and medical visits from 71.2% to 76.2%, ranging from 61.4 to 75.8% and 68.0 to 80.6% between the North and Southeast regions. There was no significant association of seeking care due to a health problem with per capita income, after controlling for the other covariates. We conclude by saying that, despite the expanded coverage of health service use, the persistent regional inequalities indicate unmet health needs among residents of the less developed regions. Health care models focused on prevention and health promotion are required.

Abstract
This paper aimed to describe health insurance coverage in Brazil. Data from the 2013 and 2019 editions of the National Health Survey (PNS) were analyzed. The medical or dental health insurance coverage was analyzed according to demographic and socioeconomic characteristics, work status, urban/rural area, and Federation Unit. Coverage of medical or dental health insurance was 27.9% (95% CI: 27.1-28.8) for 2013 and 28.5% (95% CI: 27.8-29.2) for 2019. The results show coverage is still concentrated in large urban centers, in the Southeast and South, among those with better socioeconomic status and some formal employment. In 2019, only 30.7% of formal workers reported the monthly payment is made directly to the providers, while 72.7% of informal workers reported this information. About 92% of medical health insurance covers hospitalization, and almost 20% of women with health insurance are not covered for labor. Only 11.7% of women aged between 15 and 44 are covered for childbirth by health insurance. The results show the health insurance coverage is still quite unequal, reinforcing the Unified Health System (SUS) importance for the Brazilian population.

Abstract
OBJECTIVE To analyze changes in the lifestyles of Brazilian adolescents during the COVID-19 pandemic. METHODS Cross-sectional study carried out with adolescents who participated in the survey "ConVid Adolescentes - Pesquisa de Comportamentos". The indicators related to lifestyles before and during the COVID-19 pandemic were evaluated: consumption of healthy and unhealthy foods, physical activity and sedentary behavior, smoking and consumption of alcohol. Prevalence and 95% confidence intervals were calculated for the total population and according to sex and age group. RESULTS A total of 9,470 adolescents participated in the study. During the period of social distancing, there was an increase in the prevalence of vegetables consumption (from 27.34 to 30.5%), frozen foods (from 13.26 to 17.3%), chocolates and sweets (from 48.58 to 52.51%), and time in front of screens (from 44.57 to 70.15%). On the other hand, there was a decrease in the practice of physical activity (from 28.70 to 15.74%) and in the consumption of alcohol (from 17.72 to 12.77%). Differences were observed according to sex and age group. CONCLUSION The results show changes in the lifestyle of adolescents and an increase in health risk behaviors.

Abstract
OBJECTIVE To compare lifestyle changes during the COVID-19 pandemic according to the presence or absence of noncommunicable diseases (NCDs) in Brazilian adults. METHODS Cross-sectional study, using data from the ConVid survey, between April and May 2020. The following variables were evaluated: lifestyle and presence of one or more NCDs (diabetes, hypertension, respiratory disease, heart disease, and cancer). Sociodemographic characteristics were used as adjustment. Relative frequencies and confidence intervals (CI) of 95% of the explanatory variables were calculated before and during the pandemic. For the comparison of groups, with or without NCDs, crude and adjusted (PRadj) prevalence ratios were estimated by Poisson regression. RESULTS There was a reduction in physical activity (60% in those without NCDs and 58% in those with NCDs) and in vegetable consumption (10.8% in those without NCDs and 12.7% in those with NCDs). On the other hand, there was an increase in the time spent watching television and on screens of computer/tablet (302% and 43.5% in those without NCDs and 196.5% and 30.6% with NCDs, respectively); consumption of frozen meals (43.6% in those without NCDs and 53.7% with NCDs), snacks (42.3% without NCDs and 31.2% with NCDs), and chocolate (14.8% without NCDs). During the pandemic, patients with NCDs were less active (PRadj = 0.77; 95%CI 0.65 - 0.92), had greater habit of watching TV (PRadj = 1.16; 95%CI 1.08 - 1.26), and consumed less vegetables (PRadj = 0.88; 95%CI 0.81 - 0.96). CONCLUSION It was evident that adults with NCDs had their lifestyles more altered during the COVID-19 pandemic.

Abstract
The ConVid - Behavior Survey was conducted in Brazil from April 24 to May 24, 2020, aiming to investigate changes in lifestyles and health conditions during the COVID-19 pandemic. In this article, we present the conception and methodology of the research. We used a cross-sectional study using an Internet questionnaire, with questions validated in previous health surveys. The sampling method "virtual snowball" was used, as well as post-stratification procedures. The results related to chronic non-communicable diseases and pre-pandemic lifestyles were compared with estimates from the 2013 Brazilian National Health Survey and 2019 Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Survey. The total sample was 45,161 people. After data weighing, the sample distributions of demographic variables were similar to population variables. Only people with a low schooling level were underrepresented. The comparison with the previous results showed similarity in most estimates: recommended consumption of fruits and vegetables (22.1%), recommended physical activity (35.2%), tobacco smoking habit (12.3%), frequent and abusive alcohol consumption (6.7%), obesity (21.2%), self-reported prevalence of hypertension (18.6%), diabetes (7.1%), and heart disease (4.4%). The online survey made it possible to know the population's health conditions during the pandemic. The similarity of the indicators with those obtained in traditional research allowed the validation of the mean estimates. Studies are needed to investigate how the endogenous effects of virtual social networks can be considered when estimating variance.

Abstract
This is a cross-sectional study investigating the factors affecting brazilians' self-rated health during the COVID-19 pandemic, based on data from the web-based behavior survey. Carried out from April 24 to May 24, 2020, the survey recruited participants by a chain sampling procedure. Its outcome was the worsening of self-rated health during the pandemic. Statistical analysis was based on a hierarchical model of determination. Logistic regression models were used to test the associations between sociodemographic characteristics, pre-existing health conditions, lifestyle indicators and intensity of social restraint measures, and biological and psychological issues during the pandemic. From the total sample of 45,161 participants, 29.4% reported worsening of health state during this period. After adjusting for hierarchical distal factors, the health problems mostly associated with worsening health state were: bad self-rated health (adjusted OR = 4.35, p < 0.001), health care seeking for mental health problem (adjusted OR = 3.95, p < 0.001), and for COVID-19 (adjusted OR = 3.60, p < 0.001). People who experienced sleep problems, worsening of back pain, depression and at least one flu symptom during the pandemic were twice as likely to report worsening of health status. Sedentary and eating behaviors and adherence to social distancing measures showed significant correlation with the outcome. There exists a relation between social, biological, and psychological factors, mediated by lifestyles and variables pertaining to confinement. Altogether, these factors have negatively affected self-rated health during the COVID-19 pandemic in Brazil.

Abstract
Social distancing measures adopted in various countries to mitigate the impact of the COVID-19 pandemic can lead to unwanted effects on their populations' health and behaviors. This study aimed to investigate smoking behavior in the Brazilian adult population during the COVID-19 pandemic and analyze factors associated with the increase in cigarette consumption. An online survey was performed, and the final sample included 45,160 individuals. The study used post-stratification weights and calculated crude prevalence ratios (PR) and adjusted by sex, age, and schooling, and respective 95% confidence intervals (95%CI). Poisson regression models with robust variance were applied to analyze associations between increased cigarette consumption and sociodemographic variables and adherence to social distancing, quality of sleep, state of mind, and changes in work and earnings. Prevalence of smokers was 12% (95%CI: 11.1-12.9), 34% of whom reported an increase in cigarette consumption. The increase was greater among women (PR = 1.27; 95%CI: 1.01-1.59) and individuals with incomplete secondary schooling (PR = 1.35; 95%CI: 1.02-1.79). The increase in cigarette consumption was associated with worse quality of sleep, feeling isolated from family members or sad, depressed, or anxious, loss of earnings, and worse self-rated health. Health promotion strategies, smoking prevention, and encouragement for smoking cessation, as well as mental health interventions, should be continued and reinforced in the context of social distancing during the COVID-19 pandemic.

Abstract
The goal of this study is to characterize the population of older adults in Brazil during the COVID-19 pandemic with regard to health, socioeconomic conditions, gender inequality, adherence to social distancing and feelings of sadness or depression. It is a cross-sectional study carried out with Brazilian older adults who responded to an online health survey (N = 9,173), using a "virtual snowball" sampling method. Data were collected online via a self-administered questionnaire. Prevalence and confidence interval estimates were performed and verified for independence using Pearson's chi-square test. During the pandemic there was a fall in household income among almost half of older adults. Extreme social distancing was practiced by 30.9% (95%CI: 27.8; 34.1) and 12.2% (95%CI: 10.1; 14.7) did not adhere to it. Older adults who were not working before the pandemic adhered in greater numbers to extreme social distancing measures. Most of them presented comorbidities associated with a higher risk of developing the severe form of COVID-19. Feelings of loneliness, distress and sadness were frequent among older adults, especially women. The COVID-19 pandemic widened the inequality gap by affecting the most vulnerable older people. Strategies to mitigate loneliness and social distancing should consider social vulnerability and the marked difference between men and women in terms of household composition and socioeconomic and working conditions. The development of representative surveys of Brazilian older adults is recommended, investigating the impact of the pandemic on this population.

Abstract
OBJECTIVE To analyze the frequency of sadness, nervousness, and sleep disorders during the COVID-19 pandemic in Brazil, identifying the most affected demographic segments. METHODS This was a cross-sectional study using an online questionnaire answered by adults and elderly people to collect information on living conditions, health and health-related behaviors. Prevalence rates and prevalence ratios adjusted for age and sex were estimated. RESULTS The data on 45,161 Brazilian respondents showed that during the pandemic 40.4% (95%CI 39.0;41.8) frequently felt sad or depressed and 52.6% (95%CI 51.2;54.1) frequently felt anxious or nervous; 43.5% (95%CI 41.8;45.3) reported the onset of sleep problems and 48.0% (95%CI 45.6;50.5) had a prior sleep problem that had become worse. Frequent sadness and nervousness, as well as change in sleep patterns were higher in young adults, women and those with a history of depression. CONCLUSION The high prevalence found indicates the need to guarantee the provision of services for mental health and quality of sleep that are adapted to the pandemic context.

Abstract
Objective To describe the characteristics of female sex workers (FSW) in 12 Brazilian cities. Methods This was a cross-sectional biological and behavioral surveillance study with FSW recruited by respondent-driven sampling (RDS) in 2016. HIV prevalence, sociodemographic, behavioral and sex work profession variables were estimated by city. The chi-square test was used to compare these distributions. Results Among 4,328 FSW, HIV prevalence was 5.3% (95%CI 4.5;6.3), ranging from 0.2% (95% CI 0.0;1.2), in Campo Grande, to 18.2 (95%CI 13.2;24.7) in Salvador. In half of the cities, HIV prevalence in the samples was >5.0%, while Campo Grande, Brasília and Belo Horizonte had prevalence rates <1.0%. Significant differences between cities were found in distributions according to educational level, income, workplace, age sex work started, and illicit drug use. Conclusion The characteristics of the samples in each city were distinct and have influenced local HIV prevalence.

Abstract
RESUMO O objetivo do estudo foi analisar a adesão ao distanciamento social, as repercussões no estado de ânimo e as mudanças nos estilos de vida da população adulta brasileira durante o início da pandemia da Covid-19. Estudo transversal com indivíduos adultos residentes no Brasil (n = 45.161) que participaram do inquérito de saúde virtual ConVid - Pesquisa de Comportamentos, no período de 24 de abril a 24 de maio de 2020. Da amostra estudada, apenas 1,5% levou vida normal, sem nenhuma restrição social, e 75% ficaram em casa, sendo que, destes, 15% ficaram rigorosamente em casa. Os sentimentos frequentes de tristeza ou depressão (35,5%), isolamento (41,2%) e ansiedade (41,3%) foram reportados por grande parte da população estudada. Verificou-se que 17% dos participantes reportaram aumento do consumo de bebidas alcoólicas e que 34% dos fumantes aumentaram o número de cigarros. Observou-se aumento no consumo de alimentos não saudáveis e redução da prática de atividade física no período estudado. Conclui-se que houve elevada adesão ao distanciamento social e aumento dos sentimentos de tristeza, depressão e ansiedade, bem como aumento de consumo de alimentos não saudáveis, uso de bebidas alcóolicas e cigarros e redução da prática de atividade física.

Laboratory exams of the National Health Survey: methodology of sampling, data collection and analysis. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2019; 22Suppl 02:E190004.SUPL.2. [PMID: 31596375 DOI: 10.1590/1980-549720190004.supl.2] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Accepted: 02/20/2019] [Indexed: 11/21/2022] Open
Abstract
INTRODUCTION This article aims at describing the National Health Survey (Pesquisa Nacional de Saúde- PNS) methodology of collecting laboratory exams data. METHODOLOGY A subsample of 25% of the census tracts was selected, according to the stratification of the PNS sample, with a probability inversely proportional to the difficulty of collection. The collection of blood and urine was done in the households by a laboratory agent, among residents selected for individual interview. Due to the difficulties found in the field work, the sample did not reach the minimum expected number in some strata, and a post-stratification procedure was proposed for the data analysis. RESULTS The collection of biospecimens was performed in 8,952 individuals. Laboratory tests were: glycated hemoglobin; total cholesterol; LDL cholesterol; HDL cholesterol; serology for dengue; red blood cell count (erythrogram) and white series count (leukogram); high performance liquid chromatography (HPLC) for diagnosis of hemoglobinopathies; creatinine. Theexcretion of potassium, salt and sodium and creatinine was estimated in the urine. The database of laboratory exams was weighed and made publicly available on the Oswaldo Cruz Foundation's PNS website and can be accessed without prior authorization. CONCLUSION The total subsample of laboratory exams is of great value, since it allowed us to establish national reference parameters adequate to sociodemographic and geographic characteristics of the Brazilian population, providing relevant and complementary information for the analysis of the health situation of Brazil.

Abstract
INTRODUCTION Respondent-Driven Sampling (RDS) has been used in surveys with key populations at risk of HIV infection, such as female sex workers (FSW). This article describes the application of the RDS method among FSW in 12 Brazilian cities, during a survey carried out in 2016. METHODOLOGY A biological and behavioral surveillance study carried out in 12 Brazilian cities, with a minimum sample of 350 FSW in each city. Tests were performed for HIV, syphilis, and hepatitis B and C infections. A social-behavioral questionnaire was also applied. RESULTS The sample was comprised of 4,328 FSW. For data analysis, the sample was weighted according to each participant's network size (due consideration to the implications of RDS complex design and to the effects of homophilia are recommended). DISCUSSION Although RDS methods for obtaining a statistical sample are based on strong statistical assumptions, allowing for an estimation of statistical parameters, with each new application the method has been rethought. In the analysis of whole-sample data, estimators were robust and compatible with those found in 2009. However, there were significant variations according to each city. CONCLUSION The achieved sample size was of great relevance for assessing progress and identifying problems regarding the prevention and treatment of Sexually Transmitted Infections. New RDS studies with more time and operational resources should be envisaged. This could further network development.

Abstract
INTRODUCTION Knowing the factors associated with periodic HIV testing among female sex workers (FSW) is essential to expand testing coverage and to broaden programs of treatment as prevention. METHODS We used data from 4,328 FSWs recruited by the respondent-driven sampling (RDS) method in 12 Brazilian cities in 2016. Data analysis considered the complex sampling design. The prevalence of HIV testing in the last year and periodic HIV test were estimated. Factors associated with regular HIV testing were identified through logistic regression models. RESULTS The testing coverage in the last year was 39.3%. Only 13.5% of FSW reported having performed a periodic HIV test in the last year. Among the factors associated with the higher probability of HIV testing in the last year were a better level of education, living with a partner, working indoors, consistent use of condoms, and regular use of public and private health services stood out. DISCUSSION Periodic HIV testing allows early diagnosis and immediate treatment of cases, reducing the chances of spreading the infection to the population. However, factors such as stigma and discrimination hinder the use of regular health services. CONCLUSION It is necessary to expand awareness campaigns, especially among FSWs with low educational level and greater vulnerability, in order to broaden the perception of risk and the importance of periodic testing, in addition to encouraging regular health care.

Abstract
INTRODUCTION Knowledge about risky sexual behavior among young people has been widely acknowledged as a key tool to controlling the spread of HIV. This article aimed at presenting the risk behavior of Brazilian Army conscripts toward HIV infection according to the country's geographic regions. . METHOD We collected data from 37,282 conscripts, aged 17 to 22, during enlistment in the Brazilian Army in 2016. The prevalence of HIV infection, both self-reported and measured through laboratory results, and risk behavior factors were estimated by region. RESULTS 75% of the sample of conscripts reported to have already started sexual activity, and the average age of their sexual initiation was 15. Condom use varied according to the type of sexual relationship, being lower among steady partners and greater among less stable relationships. HIV prevalence assessed by laboratory tests was 0.12% across the country and the highest prevalence was observed in the North region (0.24%). Alcohol and illicit drug usage was higher in the South region. DISCUSSION The study allowed the observation of risk behavior monitoring for HIV infection among young Brazilians. Lower condom usage among steady partners may be contributing to an increase in the number of HIV-infected individuals. CONCLUSION Results suggest the need to intensify prevention campaigns to disseminate safe sex practices among young people, in addition to the expansion of testing offer to this population.

Abstract
Background Stigma in health services may be detrimental to health seeking attitudes and practices. This study investigates non-disclosure of sex work to health care providers among female sex workers (FSW) in Brazil and its association with the utilization of health care services. Methods This study used cross-sectional respondent-driven sampling, carried out in 12 Brazilian cities to identify HIV risk behaviors among FSW. We first assessed statistical associations of sociodemographic, human right violations, health service access and utilization, and discrimination variables with non-disclosure of FSW status to health care providers as outcome. Secondly, we investigated the association of non-disclosure of FSW status with selected preventive health care outcomes: HIV testing, PAP smear exam, and post-exposure prophylaxis (PEP). Adjusted odds ratio with 95% confidence intervals were calculated by multivariable logistic regressions. Results Among 4245 recruited FSW, a high percentage received free condoms (82%) but only 24.4% were counseled on STI. Most FSW used non-specialized public healthcare routinely (62.6%), but only 51.5% had a Pap smear exam in the last two years and less than 40% were tested for HIV in the last 12 months. Among FSW who engaged in risky behavior (49.6%), only 8.3% used PEP. Regarding human rights violations, approximately 15% were required to give part of their earnings to owners of workplace establishments, 38% started sex work under 18 years old and 6% were required to periodically present their HIV test results. 21.3% reported having faced discrimination in health services, and 24.3% always disclosed their FSW status. Multivariable logistic models indicated significant associations of non-disclosure on the four healthcare outcomes, with lower odds of using preventive health services among women who did not disclose their sex work status, even after controlling for age, educational level, NGO affiliation, and type of health care routinely used. Conclusions Our results indicate that sex work stigmatization within health services may be one of the main barriers to STI control and HIV response among FSW. It is essential to combat stigmatization and discrimination against FSW in health services to guarantee the appropriate uptake of preventive services available in the public health system in Brazil.

Abstract
Resumo: Neste trabalho, avaliam-se quantitativa e qualitativamente as informações do Sistema de Informações sobre Nascidos Vivos (SINASC). A cobertura das informações por município foi estimada pela razão entre nascidos vivos informados e estimados. Para avaliação da qualidade das informações do SINASC, relacionou-se o sistema à base de dados do estudo Nascer no Brasil, 2011-2012, e foram estimados coeficientes kappa de concordância. Em 2013, a cobertura das informações foi alta e homogênea em todas as Unidades da Federação. Entretanto, a análise por município brasileiro apresentou maior heterogeneidade espacial. Quanto à qualidade de preenchimento das informações do SINASC, os coeficientes kappa de concordância foram estatisticamente diferentes de zero para todas as variáveis testadas (p < 0,001), e as distribuições marginais para todas as variáveis consideradas foram semelhantes nas duas bases de dados. A idade gestacional foi a variável que mostrou pior concordância, com valor de kappa de 0,461. O indicador que descreve as inconsistências, medido pela soma do quadrado das diferenças entre os percentuais de prematuridade informados e esperados por faixa de peso ao nascer, teve o valor mais alto na Região Norte e o menor na Região Sul, apontando para desigualdades geográficas na mensuração da idade gestacional.

Abstract
RESUMO: Objetivo: Analisar as prevalências de diabetes mellitus segundo diferentes critérios diagnósticos, na população adulta brasileira, segundo os resultados laboratoriais da Pesquisa Nacional de Saúde. Métodos: Análise dos dados laboratoriais da Pesquisa Nacional de Saúde, coletados entre os anos de 2014 e 2015. Foram calculadas as prevalências de diabetes conforme diferentes critérios diagnósticos. Foram calculadas as prevalências de diabetes segundo o critério de hemoglobina glicosilada ≥ 6,5% ou em uso de medicamentos, empregando regressão de Poisson para o cálculo da razão de prevalência (RP) bruta e ajustada e intervalo de confiança de 95% (IC95%). Resultados: A prevalência de diabetes segundo diferentes critérios pode variar 6,6 a 9,4%; e a hiperglicemia intermediária, ou pré-diabetes, de 6,8 a 16,9%. Usando-se o critério laboratorial ou uso de medicamentos, a prevalência de diabetes foi de 8,4%. A RP ajustada para sexo, idade, escolaridade e região foi menor no sexo masculino (RP = 0,75; IC95% 0,63 - 0,89); aumentou com a idade: 30 a 34 anos (RP=2,32; IC95% 1,33 - 4,07), 40 a 59 anos (RP = 8,1; IC95% 4,86 - 13,46), 60 anos ou mais (RP = 12,6; IC95% 7,1 - 21,0); e a escolaridade elevada foi protetora (RP = 0,8; IC95% 0,6 - 0,9). Maior RP foi encontrada na Região Centro-Oeste (RP = 1,3; IC95% 1,04 - 1,7) e naqueles com sobrepeso (RP = 1,8; IC95% 1,4 - 2,1) e obesidade (RP = 3,3; IC95% 2,6 - 4,1). Conclusão: A prevalência de diabetes foi maior no sexo feminino, naqueles com idade maior que 30 anos, em população com baixa escolaridade, com excesso de peso e obesidade. Os critérios laboratoriais são mais fidedignos para o conhecimento da situação real do diabetes no país.

Abstract
RESUMO: Introdução: A prevalência de obesidade está aumentando em um ritmo alarmante em muitos países. Uma alimentação não saudável e o sedentarismo são os principais fatores de risco para a obesidade. O objetivo deste artigo foi estudar a prevalência e identificar fatores associados à obesidade na população adulta brasileira com base nos dados coletados na Pesquisa Nacional de Saúde, 2013. Método: Amostra de 59.402 indivíduos adultos, excluindo-se as mulheres grávidas. O índice de massa corporal foi calculado por meio das aferições de peso e estatura. A obesidade foi definida por índice de massa corporal ≥ 30 kg/m2. Utilizaram-se modelos de regressão logística para identificar os fatores associados à obesidade. Resultados: As prevalências de obesidade foram de 16,8% para homens e 24,4% para mulheres. Idade avançada (a partir dos 50 anos), nível de instrução baixo (sem instrução ou ensino fundamental incompleto), raça/cor preta e viver com companheiro foram fatores de risco à obesidade. A atividade física no lazer e o hábito de assistir mais de 4 horas de televisão por dia mostraram associações significativas para ambos os sexos. Quanto à morbidade referida, em pessoas obesas, as chances de ter o diagnóstico de hipertensão, diabetes ou de alguma doença crônica não transmissível foram maiores. Homens e mulheres obesos tiveram a pressão arterial sistólica significativamente aumentada. Conclusão: Os achados enfatizam a importância de políticas públicas para a prevenção da obesidade e para a promoção de hábitos saudáveis na sociedade brasileira.

Abstract
BACKGROUND Female sex workers (FSW) bear a high burden of sexually transmitted infections (STI). In this paper, we estimate the prevalence of human immunodeficiency virus (HIV), HBV = hepatitis B virus (HBV), HCV = hepatitis C virus (HCV), syphilis and co-infections in the second Biological and Behavioral Surveillance Survey among FSW in Brazil. METHOD The survey was conducted in 12 Brazilian cities from July to November 2016. We used respondent-driven sampling (RDS) to recruit 350 FSW in each city. Rapid tests were used for screening HIV, syphilis, HCV, and HBV. Confirmatory tests were performed on all samples with reactive rapid test result. All testing algorithms and interpretations were done according to the recommendations of the Department of STI/AIDS and viral hepatitis, Ministry of Health. The STI diagnoses were given by: confirmed HIV infection by a positive result on Western blot; active syphilis infection, defined by a RPR titer equal or greater than 1/8; viremia period of HBV and HCV infections, characterized by a detectable (or quantifiable) viral load. Prevalence estimates and standard errors were calculated using statistical procedures suitable for data collected by RDS. RESULTS Excluding the seeds, 4245 FSW were enrolled. Prevalence estimates were: HIV 5.3% (95% CI: 4.4%-6.2%); active syphilis 8.5% (95% CI: 7.3%-9.7%); HBV 0.4% (95% CI: 0.2%-0.7%); and, HCV 0.9% (95% CI: 0.6%-1.3%). Among the 4154 FSW tested for the 4 infections, 13.3%; (95% CI 12.0%-14.8%) were diagnosed with at least one of the infections, of which 87.6% (95% CI: 83.3%-90.9%) had single infections. The prevalence of HIV/syphilis co-infection was 1.09% (95% CI: 0.7%- 1.6%) and of HIV/HCV or HBV infections was 0.4% (95% CI: 0.2%-0.7%). CONCLUSIONS Our results reveal the need to conduct more studies to estimate the prevalence of STI and co-infections among FSW in Brazil. Longitudinal trends in the prevalence estimates of HIV and other STI provide information to monitor changes in this high-risk population. Additionally, the study highlights the importance of measuring the hepatitis burden among FSW living with HIV, and the need of including FSW in all aspects of STI prevention, care, and treatment programs.

Abstract
BACKGROUND Female sex workers (FSWs) are one of the most-at-risk population groups for human immunodeficiency virus (HIV) infection. This paper aims at identifying the main predictors of HIV infection among FSW recruited in the 2nd Biological and Behavioral Surveillance Survey in 12 Brazilian cities in 2016. METHOD Data were collected on 4245 FSW recruited by respondent driven sampling (RDS). Weights were inversely proportional to participants' network sizes. To establish the correlates of HIV infection, we used logistic regression models taking into account the dependence of observations resultant from the recruitment chains. The analysis included socio-demographic sex work characteristics, sexual behavior, history of violence, alcohol and drug use, utilization of health services, and occurrence of other sexually transmitted infections (STIs). RESULTS HIV prevalence was estimated as 5.3% (4.4%-6.2%). The odds ratio (OR) of an HIV-positive recruiter choosing an HIV-positive participant was 3.9 times higher than that of an HIV-negative recruiter (P < .001). Regarding socio-demographic and sex work characteristics, low educational level, street as the main work venue, low price per sexual encounter, and longer exposure time as a sex worker were found to be associated with HIV infection, even after controlling for the homophily effect. The OR of being HIV infected among FSW who had been exposed to sexual violence at least once in a lifetime (OR = 1.5, P = .028) and the use of illicit drugs at least once a week were highly significant as well, particularly for frequent crack use (OR = 3.6, P < .001). Among the sexual behavior indicators, not using condoms in some circumstances were significantly associated with HIV infection (OR = 1.8, P = .016). Regarding the occurrence of other STI, the odds of being HIV infected was significantly higher among FSW with a reactive treponemal test for syphilis (OR = 4.6, P < .001). CONCLUSIONS The main factors associated with HIV infection identified in our study characterize a specific type of street-based sex work in Brazil and provided valuable information for developing interventions. However, there is a further need of addressing social and contextual factors, including illicit drug use, violence, exploitation, as well as stigma and discrimination, which can influence sexual behavior.

BACKGROUND The present study aims at investigating the progress made toward controlling the human immunodeficiency virus (HIV)/AIDS epidemic among female sex workers (FSW) from 2009 to 2016. METHODS The baseline of respondent-driven sampling (RDS) study among FSW was carried out in 2009, in 10 Brazilian municipalities. In 2016, information on FSW were collected in 12 municipalities. The analyses took into account the dependence among observations, resulting from the recruitment chains, and the unequal probabilities of selection, resulting from the different network sizes. We analyzed changes in attitudes and risky behavior practices as well as variations in HIV and syphilis prevalence based on the comparison of 95% confidence intervals for each estimate. RESULTS Information on 2523 (2009) and 4245 (2016) FSW were analyzed. Commercial sex debut shifted to younger ages: while in 2009 the proportion of women who started sex work under 18 years old was 28.3%, in 2016 this percentage rose to 38.3%. The proportion of FSW affiliated to a nongovernmental organization (NGO) in defense of their rights (14.0%), in 2009, decreased to 7.8%, in 2016, as well as the proportion of FSW who received counseling on sexually transmitted infections (STI) in the past 6 months, from 47.5% to 24.4%. Relevant improvements were found for HIV testing in the last 12 months (from 20.3% to 39.3%). The proportions of those who were never tested for syphilis dropped from 57.9% to 48.5%. However, an opposite decreasing trend was found for the Pap smear examination in the last 12 months, decreasing from 43.6% to 31.5%. Regular condom use with clients significantly increased in the period. Regarding HIV prevalence, the 5% level was sustained and no significant differences were found, but syphilis prevalence was found to be more than 3 times higher in 2016 (8.5%) than in 2009 (2.4%). DISCUSSION Many are the challenges to be faced in attempting to reverse the upward trend of syphilis among FSW in Brazil. Despite the progress in condom distribution free of charge, it is necessary to increase awareness campaigns, emphasize the use, reaffirm STI counseling, and reiterate the need of regular syphilis screening in this key population group.

Abstract
In 2015, a community-wide intervention was launched in the city of Curitiba to evaluate the uptake of multiple HIV testing. A three-stage cluster sampling of 4800 men aged 15-64 years was selected in Curitiba. Logistic regression models were used to establish driving factors of HIV testing over the past 12 months. In the total sample, 49.5% have tested for HIV once in lifetime and 18.7% in the last 12 months. Among MSM, the proportions were much higher: 75.9% and 47.8% respectively. In the multivariate analysis, a significantly higher likelihood of HIV testing was found for young men (15-24 years), men with better educational level, those with more than 6 casual partners, and MSM compared to heterosexual men. The results indicate that the intervention to increase HIV diagnosis has substantially expanded MSM access to HIV testing.

Factors associated with perceived discrimination in health services of Brazil: Results of the Brazilian National Health Survey, 2013. CIENCIA & SAUDE COLETIVA 2017; 21:371-8. [PMID: 26910145 DOI: 10.1590/1413-81232015212.19412015] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2015] [Accepted: 11/11/2015] [Indexed: 11/21/2022] Open
Abstract
The objective of this study was to evaluate factors associated with perceived discrimination in the health services of Brazil. It is a population-based epidemiological study using data from the 2013 National Health Survey, which had a complex sample design in three phases. For each domicile sampled, one individual aged 18 or over was selected (resulting in n = 62,202). The outcome analyzed was: Perception of discrimination by doctors or health professionals, suffered in the health services. A logistic regression model was estimated, adjusted for confounding factors. Discrimination was reported by 10.5% of the Brazilian population. The factors most frequently indicated were: lack of money (5.7%); and social class (5.6%). The adjusted model showed that the groups with the highest chance of feeling discriminated against were: women; individuals without complete primary education; non-whites; and those without a health insurance plan. The fact that one-tenth of the Brazilian population reported feeling discriminated against in the health services shows the need for regulation and wide debate in relation to the Brazilian laws that guarantee universal and equal access to the public and private health services.

Determinants of self-rated health and the influence of healthy behaviors: results from the National Health Survey, 2013. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2017; 18 Suppl 2:33-44. [PMID: 27008601 DOI: 10.1590/1980-5497201500060004] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2015] [Accepted: 07/13/2015] [Indexed: 11/21/2022] Open
Abstract
OBJECTIVE To investigate the determinants of self-rated health in Brazil and the influence of healthy lifestyles. METHODS We used data from the National Health Survey (PNS), 2013. The self-rated health was categorized as very good/good, fair, and poor/very poor. Differences in the distribution of self-rated health according to the age group and sex were tested. Logistic regression models were used to test the effects of educational level, race/skin color, and the presence of at least one noncommunicable chronic disease on poor/very poor health perception. In addition, the influence of healthy behaviors was tested controlling for the effects of sociodemographic factors and the presence of at least one chronic disease. RESULTS We analyzed 60,202 individuals; about 66.1% rated their health as very good/good and 5.9% as poor/very poor; about 47.1% reported the diagnosis of at least one noncommunicable chronic disease; and only 9.3% reported a "healthy lifestyle" (do not use tobacco products, consume fruits and vegetables properly, and do physical activity during leisure time). Among the sociodemographic factors, age, sex, educational level, and race were significantly associated with self-rated health and the presence of at least one chronic disease. The effects of all healthy behaviors were statistically significant even after controlling for the other determinants. CONCLUSION Although the adoption of healthy lifestyles in Brazil is still insufficient, the association of healthy practices with self-perception of health found in this study is an indication that the Brazilian population is beginning to relate healthy behaviors to their well-being and better health evaluation.

Prevalence of chronic non-communicable diseases and association with self-rated health: National Health Survey, 2013. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2017; 18 Suppl 2:83-96. [PMID: 27008605 DOI: 10.1590/1980-5497201500060008] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2015] [Accepted: 07/16/2015] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE To analyze the profile of 10 chronic noncommunicable diseases investigated in the National Health Survey carried out in Brazil in 2013 and their association with the self-rated health. METHODS A cross-sectional, population-based nationwide study with 60,202 individuals aged 18 years old or more. Sampling process by conglomerate was carried out in three stages of selection: census tract, household, and individual. The prevalence of chronic diseases by age, gender and educational status and the confidence intervals of 95% , the mean age at the first diagnosis and the proportion of limitation of the usual activities were calculated. To test the association with self-rated health, the logistic regression procedure adjusted for gender and age was used. RESULTS The more prevalent diseases were hypertension (21.4%), depression (7.6%), arthritis (6.4%), and diabetes mellitus (6.2%). Individuals diagnosed with stroke reported greater limitations in the daily activities (38.6%). There was a gradient in the prevalence by age and educational level, and all the diseases were more frequent among women. A worse self-rated health was observed among those with a diagnosis of stroke (OR = 3.60; p < 0.001) and those who referred two diseases (OR = 5.53; p < 0.001) or three or more diseases (OR = 10.86; p < 0.001). CONCLUSIONS Because these diseases are associated with modifiable risk factors, the prevention with population focus is the best strategy to reduce the burden of these diseases.

Recommendations and practice of healthy behaviors among patients with diagnosis and diabetes in Brazil: National Health Survey (PNS), 2013. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2017; 18 Suppl 2:132-45. [PMID: 27008609 DOI: 10.1590/1980-5497201500060012] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2015] [Accepted: 06/23/2015] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE To analyze healthy life style recommendations given in health care and the adoption of healthy behaviors among hypertension and diabetes patients. METHODS We analyzed the recommendations according to the place of the last health care visit (primary health care, other public facilities, and private health care facilities). The effects of having a diagnosis of hypertension or diabetes on the adoption of healthy practices were analyzed by multivariate logistic regression models, using sex, age, and educational level as control variables, and the following outcomes: current use of tobacco products; regular physical activity during leisure time; recommended intake of fruits and vegetables; perception of low salt intake; frequent consumption of sweets; and excessive alcohol consumption. RESULTS Approximately 88% of hypertension patients received recommendations to have a healthy diet, 91% to eat less salt, 83% to practice regular physical activity, and 76% to not to smoke. Among diabetic patients, all recommendations related to nutrition were very frequent, reaching 95% for the habit of having fruits and vegetables regularly. The effect of having a diagnosis of hypertension was significant for non-use of tobacco products and perception of low salt intake. The diagnosis of diabetes mainly influenced the habit of not consuming sweets often. CONCLUSION Results evidenced that people with diagnosis of hypertension and diabetes give priority to not use (stop) harmful health behaviors than to adopt practices that will bring benefits to their health. It is necessary to promote not only the adverse effects of harmful habits, but also the benefits of healthy behaviors to aging well.

Inequalities in healthy life expectancy by Federated States. Rev Saude Publica 2017; 51:7s. [PMID: 28591354 PMCID: PMC5676373 DOI: 10.1590/s1518-8787.2017051000105] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Accepted: 10/23/2016] [Indexed: 12/03/2022] Open
Abstract
OBJECTIVES To estimate the healthy life expectancy at 60 years by sex and Federated States and to investigate geographical inequalities by socioeconomic status. METHODS Healthy life expectancy was estimated by the Sullivan method, based on the information of the National Survey on Health, 2013. Three criteria were adopted for the definition of “unhealthy state”: self-assessment of bad health, functionality for performing the activities of daily living, and the presence of noncommunicable disease with intense degree of limitation. The indicator of socioeconomic status was built based on the number of goods at household and educational level of the head of household. To analyze the geographical inequalities and socioeconomic level, inequality measures were calculated, such as the ratio, the difference, and the angular coefficient. RESULTS Healthy life expectancy among men ranged from 13.8 (Alagoas) to 20.9 (Espírito Santo) for the self-assessment criterion of bad health. Among women, the corresponding estimates were always higher and ranged from 14.9 (Maranhão) to 22.2 (São Paulo). As to the ratio of inequality by Federated State, the medians were always higher for healthy life expectancy than for life expectancy, regardless of the definition adopted for healthy state. Regarding the differences per Federated State, the healthy life expectancy was seven years higher in one state than in another. By socioeconomic status, differences of three and four years were found, approximately, between the last and first fifth, for men and women, respectively. CONCLUSIONS Despite the association of the mortality indicators with living conditions, the inequalities are even more pronounced when the welfare and the limitations in usual activities are considered, showing the necessity to promote actions and programs to reduce the socio-spatial gradient.

Early detection of breast cancer in Brazil: data from the National Health Survey, 2013. Rev Saude Publica 2017; 51:14s. [PMID: 28591356 PMCID: PMC5676402 DOI: 10.1590/s1518-8787.2017051000191] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2016] [Accepted: 09/06/2016] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE To analyze whether the actions of early detection of breast cancer, initiated with the medical request for mammography, differ between users of the Brazilian Unified Health System (SUS) and those who have private health insurance. METHODS From the data collected in the National Health Survey, we estimated the proportions of women who had medical request for mammography according to presence or absence of private health insurance. For assessing the factors related to having mammography medical request, we estimated crude and adjusted odds ratios and respective 95%CI by logistic regression. We also analyzed the main reasons reported for not having performed mammography after medical request, as well as the time between examination and result. RESULTS Of the women interviewed, 66.7% had a medical request for mammography (59.4% among SUS users and 83.9% among those with private health insurance). Having private health insurance, higher education level, and being white were positively associated with having the medical request. Only 5.4% (95%CI 4.8-6.0) of women who received medical request failed to perform mammography - 7.6% were SUS users and 1.7% had health insurance. The most reported reasons for not being able to perform the examination were: not thinking it was necessary; having the test scheduled, but not yet performed; and not being able to schedule it. More than 70% of women received the result with less than one month from its execution. CONCLUSIONS The barriers to access a medical request for mammographic screening for breast cancer are higher among women who depend exclusively on SUS.
