National Health Survey 2019: history, methods and perspectives

Racial Inequality in the Prevalence of Symptom-Based Depression Versus Self-Reported Medical Diagnosis in Brazil

A cross-sectional study was conducted with Brazilian adults from the 2019 Pesquisa Nacional de Saúde (PNS 2019; National Health Survey, in English) who self-declared race/skin color white or black (n = 87,187), to investigate racial inequality in the prevalence of symptom-based versus self-reported depression. Symptom-based depression was screened using the Patient Health Questionnaire-9 (cutoff ≥ 10), while medical diagnosis was self-reported. Prevalence of agreement (presence of medical diagnosis among those with symptoms) and disagreement (absence of medical diagnosis among those with symptoms) were compared according to race/skin color. The Odds Ratio (OR) for the association between both depression indicators and race/skin color were estimated by Logistic regression adjusted by socioeconomic variables. The black population had a higher prevalence of symptom-based depression than medical diagnosis (11.0% versus 8.6%; 2.5 percentual points (pp)), with greater differences among younger adults (6.0 pp), without a partner (3.6 pp), with lower income (3.9 pp), education (3.0 pp), less developed regions (north: 3.6 pp; northeast: 4.2 pp) and those with recent access to medical care (4.5 pp). The white population had a higher prevalence of medical diagnosis than symptom-based depression (10.6% versus 12.5%; -1.9 pp), with greater differences between those with higher income (-7.4 pp), education (-4.5 pp) and from south region (-6.0 pp). Disagreement was higher among black individuals while agreement was higher among white, with significant inequality among women for both agreement (33.5% in black versus 41.7% in white) and disagreement (66.5% in black versus 58.3% in white). The black population had a lower chance of having medical diagnosis of depression (OR 0.77; 95%CI 0.70-0.84) than white, regardless of socioeconomic variables. Racial inequality was identified in the prevalence of symptom-based versus self-reported depression, with greater inequality among women and those with lower income and education.

Disparity in meat consumption: An obstacle to achieving the golden rule of the Brazilian Dietary Guidelines?

OBJECTIVE

To investigate disparities in meat consumption in Brazil and analyze its relationship with the intake of fresh fruits and vegetables.

METHODS

This is a cross-sectional study using secondary data from the 2019 National Health Survey. Red meat consumption (in days) was estimated according to socioeconomic and demographic data. Odds ratios (OR) were estimated using multinomial logistic regression, and the association between meat consumption and fruit and vegetable intake was assessed by means of Poisson regression.

RESULTS

Of a total of 83,085 Brazilians participating in the study, 29.2% reported consuming meat 5-7 times per week. Sociodemographic and economic factors revealed a lower likelihood of consuming meat 5-7 days/week among women [OR 0.50, 95%CI 0.46; 0.53), older adults (OR 0.48, 95%CI 0.37; 0.63) and residents of the Northeast region of the country (OR 0.72, 95%CI 0.66; 0.79). After adjustments, red meat consumption was directly associated (p-value<0.001) with vegetable intake (0.04) and inversely associated with fruit intake (-0.04).

CONCLUSION

Meat consumption is unequal among Brazilians and may have an impact on the consumption of fresh foods, such as fruits.

Progress in Physical Activity Surveillance, Research, Policy, and Gender Equity in Brazil: Results From the Global Observatory for Physical Activity

BACKGROUND

Physical activity benefits both individuals and societies. This article evaluates progress in physical activity surveillance, research, policy, and authorship gender equity in Brazil (1950-2019).

METHODS

We used data from a systematic review and the country cards produced by the Global Observatory for Physical Activity. Brazilian articles identified in the review were classified according to research theme and gender distribution in authorship. We also assessed the changes in physical activity policy and surveillance in Brazil.

RESULTS

Of the 23,860 articles identified in the global review, 1200 (5.0%) were from Brazil. There was a sharp increase in publications from the 2000s, but a slight decline has been observed since 2015. Most studies were on physical activity surveillance (37%). The proportion of females as first authors was 51.2% in the last decade analyzed (2010-2019)-however, the proportion of female senior authors was below 40%. Brazil has a comprehensive surveillance system that includes all ages in periodic physical activity monitoring. Brazil has a physical activity policy embedded in noncommunicable diseases and health promotion policies, has recently launched guidelines for the population, and has a wide range of policies embedded in the national public health system.

CONCLUSION

Brazil is a leading middle-income country regarding physical activity research, policy, and surveillance. The results revealed some gender disparity in leadership roles in publications. The next challenge is translating this progress into increased physical activity levels among the Brazilian population.

[Binge drinking in Northeastern Brazil according to race/skin color]

This study aimed to analyze the factors associated with binge drinking in Northeastern Brazil according to race/skin color. A cross-sectional study was carried out with data from the 2019 Brazilian National Health Survey regarding individuals aged 18 years or older. The binge drinking outcome was measured by the consumption of five or more doses of alcoholic beverages on a single occasion in the previous 30 days. A Poisson regression with robust variance was used to evaluate the association between sociodemographic, lifestyle, and health/disease variables. The analyses were stratified by race/skin color. The prevalence of binge drinking equaled 16.6% in white people and 17.6% in black ones, occurring more often, for both strata, in men, younger people, those without a partner, those with higher per capita household income, those under paid work, physically active individuals, smokers, and those with inadequate eating habits. Higher schooling, seeking no health services, and negative self-perceived health remained associated with binge drinking only in black individuals and with three or more chronic diseases and overweight/obesity in white ones. Sociodemographic, lifestyle, and health/disease characteristics were associated with binge drinking. Health/disease factors associated with binge drinking differed between race/skin color groups. Results reinforce the importance of implementing intersectoral actions involving health and regulatory agencies to reduce the consumption of alcoholic beverages and prioritize the most vulnerable groups.

Understanding the Interplay of Interpersonal Violence, Smoking, and Alcohol Consumption in Brazilian Adults: Evidence from a National Health Survey

Interpersonal violence (IV) in adulthood seems to be related to alcoholism and smoking. However, whether it reflects differently by gender and the frequency of exposure to these outcomes remains largely unexplored, particularly in developing countries. This study aimed to evaluate associations of acute and chronic IV exposure (physical, psychological, and sexual) with binge drinking and smoking, separately for men and women adults. Cross-sectional study, enrolled 72.597 participants, aged 18 to 64, from the Brazilian National Health Survey (NHS). The explanatory variables of interest were physical, sexual, and psychological exposure to IV in the last 12 months, whether once or some/many times. The dependent variables were binge drinking and smoking. The magnitudes of associations and their confidence Interval of 95% between each exposure and outcome were estimated using Poisson regression with robust variance. Sequential adjustments were made for age, race/skin color, marital status and sexual orientation, education, and income. After adjustment for all covariates, men exposed to physical, psychological (both once or some/many times), and sexual violence (only once) were associated with binge drinking and smoking (p < .05). Further, women exposed to any form of violence, whether once or some/many times, were associated with binge drinking (p < .05). However, remained related to smoking women exposed to physical (both once or some/many times) and psychological violence (only some/many times) (p < .05). Interestingly, any frequency of sexual violence remained not associated with smoking. Women's higher exposure to violence is strongly linked to binge drinking, particularly in cases of physical and psychological violence. Men exposed to violence also exhibit significant associations with binge drinking and smoking. These findings emphasize the complex interplay of gender, violence, and public health challenges in Brazil.

Social Markers of Differences in Fruit and/or Vegetable Consumption Among Brazilians: An Intersectional Analysis

OBJECTIVE

The objective of this study was to examine the differences in fruit and/or vegetable consumption (FVC) among Brazilian adults by examining various social markers, such as gender, race, income, and education level.

METHOD

A cross-sectional study of 88,531 Brazilian adults aged 18 years or older who participated in the 2019 National Health Survey was conducted. The dependent variable was irregular FVC (<5 d/wk). Individuals at the highest risk for irregular FVC include those who are men and Black and who have lower education levels and lower income. Individuals at lower risk include those who are women and White and who have higher education levels and higher income. The prevalence of irregular FVC was calculated considering the levels of the social risk index for FVC and the intersections among two, three, and four risk categories. Odds ratio (OR) and 95% confidence interval (CI) analyses were performed to compare groups at higher risk with those at lower risk.

RESULTS

The prevalence of irregular FVC was 57.2% in the general population, 38.1% for individuals in the lowest risk group, 47.5% for individuals in one risk category, 57.9% for individuals in two risk categories, 67.6% for individuals in three risk categories, and 74.4% for individuals in the highest-risk group, and there were significant differences at each level. The highest risk group had a 4.36 (95% CI, 3.86-4.92) times greater chance of irregular FVC.

CONCLUSIONS

The complex path to promote FVC among the Brazilian population underscores the need for intersectoral policies aimed at reducing inequalities.

Relationship between cardiorespiratory fitness and falls in older adults: A population-based study

AIM

The present study investigated the relationship between cardiorespiratory fitness (CRF) and episodes and severity of falls in older adults.

METHODS

This cross-sectional study drew on data from the Brazilian 2019 National Health Survey. The sample consisted of 18 991 older adults (aged ≥60 years). CRF was obtained through a non-exercise model for estimating VO2max, and the people were classified as low, moderate or high CRF. Logistic and multinomial regression models were used. Odds ratios (ORs) and their respective confidence intervals (95% CIs) were calculated.

RESULTS

Older adults with strong CRF are 29% (OR 0.69, 95% CI 0.52-0.92) less likely to suffer falls than those with poor CRF. High levels of CRF were also associated with non-severe falls. However, no associations were found between CRF and severe falls with fractures and medical intervention.

CONCLUSION

Although good CRF levels can reduce the chance of falls, this protection does not extend to falls with more severe consequences, such as fractures and the need to seek medical care. Geriatr Gerontol Int 2025; 25: 167-172.

Prenatal tests in Brazil: prevalence and associated factors according to the Brazilian National Health Survey

OBJECTIVE

To analyze the prevalence of prenatal tests of pregnant women and factors associated with variation in this prevalence in the years of the Brazilian National Health Survey 2013 and 2019.

METHOD

A cross-sectional study, carried out with women who underwent prenatal care, interviewed in the Brazilian National Health Survey 2013 (n = 1,851) and 2019 (n = 2,729).

RESULTS

The most prevalent tests were urine and blood, and the least prevalent were syphilis and HIV. During the period, the number of tests for syphilis (15.2; 95% CI: 11.0; 22.0) and HIV (4.3; 95% CI: 4.3; 8.0) increased, but the number of tests for the others decreased. The prevalence of tests for the four tests increased and reached 69.9% (95% CI: 67.0; 72.8) in 2019 compared to 60% (95% CI: 56.1; 63.9) in 2013.

CONCLUSION

There was a greater number of prenatal tests performed, specifically for syphilis and HIV, rather than a reduction in the number of blood and urine tests. Despite the increase in access to all tests for the most vulnerable groups and locations in the country, prevalence in these groups is still low.

Mapping of the trans population in the Baixada Santista region, Brazil, 2023: a descriptive study

OBJECTIVE

To describe the socioeconomic and demographic characteristics of the trans population in the Baixada Santista region, São Paulo state.

METHODS

This was a descriptive study involving adult trans people, selected through convenience sampling in 2023. A quantitative questionnaire was administered and in-depth interviews were conducted, which were analyzed using thematic grouping.

RESULTS

A total of 237 people were recruited. Of these, 42.2% identified as trans women/travestis and 36.3% as trans men/ transmasculine; 65.4% were aged up to 29 years; 51.1% self-identified as White race/skin color; 52.7% were single; 80.5% had completed at least high school; 32.5% reported no income. Self-perception of transgender identity occurred predominantly between the ages of 10 and 19 (55.7%), with social transition beginning between the ages of 15 and 19 (41.8%). Fourteen in-depth interviews were conducted.

CONCLUSION

Socioeconomic factors - education level, employment and income - are central to gender identity. Public actions and policies need to be developed and improved.

Prevalence of depressive disorders among pregnant women in Brazil in 2019: A descriptive cross-sectional study

BACKGROUND

Prenatal depression threatens maternal and child well-being and interferes with issues prioritized by the 2030 agenda for the Sustainable Development Goals.

OBJECTIVES

This study aimed to estimate the prevalence of depressive disorders during pregnancy using the Patient Health Questionnaire-9 (PHQ-9).

DESIGN AND SETTING

A cross-sectional study using a sample of pregnant Brazilian women, representative of Brazil as a whole.

METHODS

Data were obtained from the National Health Survey 2019 (PNS-2019), as coordinated by the Instituto Brasileiro de Geografia e Estatística (IBGE). Women aged 18-49 years who were pregnant during PNS-2019 data collection were included. The prevalence of depressive disorders and 95% confidence intervals (95%CI) were calculated.

RESULTS

The prevalence of depression before the current pregnancy was 6.03% (95%CI: 3.80%; 8.25%). Using the PHQ-9, the prevalence of Major Depressive Disorder (MDD) in the current pregnancy was estimated to be 17.39% (95%CI: 12.70%-22.06%) among pregnant women who were targeted by the PNS-2019. Moreover, MDD was 15.26% (95%CI: 10.54%; 19.97%) among those who were free from depression history and in half of the pregnant woman population with depression history. Suicidal ideation has been reported in almost 23% of pregnant women with a history of depression. The two items from Patient Health Questionnaire-2 (PHQ-2) (anhedonia and depressed mood) with a cutoff of ≥ 3 presented similar results.

CONCLUSIONS

Depression during pregnancy affects a non-negligible proportion of pregnant women, thus constituting an important public health problem. Therefore, it is crucial to discuss the implementation of regular screening for depression during prenatal care programs in Brazil.

Effect of primary health care on the association between multimorbidity and emergency service utilization: National Health Survey, 2019

OBJECTIVE

To examine the effect of Primary Health Care (PHC) on the association between multimorbidity and emergency service utilization among adults in Brazil.

METHODS

This is a cross-sectional, nationwide household-based study using data from the 2019 National Health Survey. Poisson regression was used to assess emergency service utilization among individuals with multimorbidity. The interaction of variables such as Family Health coverage and orientation to PHC in these associations was also evaluated.

RESULTS

The prevalence of multimorbidity was 31.2% (95%CI 30.9-31.5), Family Health coverage was 71.8% (95%CI 71.4-72.0), and low orientation of services toward PHC was 70% (95%CI 69.1-70.9). Emergency service utilization had a prevalence of 2.0% (95%CI 1.9-2.0), being twice as high among individuals with multimorbidity (3.1; 95%CI 2.9-3.3) compared to those without this condition (1.4; 95%CI 1.3-1.5). However, individuals with multimorbidity and Family Health coverage had a 20% lower prevalence of emergency service utilization than those without Family Health coverage (PR 0.8; 95%CI 0.6-0.9). The association between emergency service utilization and multimorbidity was not modified by the evaluation of the service as highly oriented toward PHC (p=0.956).

CONCLUSION

The study showed that Family Health coverage exerted a positive effect on the association between multimorbidity and emergency service utilization.

Chronic noncommunicable diseases and absenteeism from work: National Survey of Health, 2019

OBJECTIVE

To evaluate the association between burden of disease and multimorbidity and absenteeism in Brazil.

METHODS

This is a cross-sectional study using data from the National Survey of Health 2019. The assessed outcome was absenteeism from work. The burden of disease was assessed by simply counting a list of 14 morbidities and multimorbidity was defined as: ≥two chronic diseases. Poisson regression models stratified by sex were used to estimate crude and adjusted prevalence ratios and their respective 95% confidence intervals.

RESULTS

Of the 96,131,029 employed individuals, 38.5% reported absenteeism (95%CI 32.9-44.3). The most prevalent morbidities among women who reported absenteeism were back problems (50.8%), depression (42.9%), and hypertension (41.6%); and among men, hypertension (39.7%), chronic back pain (34.1%), and dyslipidemia (19.9%), among those who reported absenteeism. Having multimorbidity increased the report of absenteeism among women by 73% (95%CI 1.01-2.96); among men, there was no association after progressive adjustment for sociodemographic and health factors [PR 1.27 (95%CI 0.96-1.71)].

CONCLUSION

The burden of disease and multimorbidity are highly prevalent among employed individuals and are strongly related to absenteeism from work, especially among women. In this sense, workers must be the target of interventions to reduce the impact of chronic noncommunicable diseases.

Sexual Orientation-Motivated Violent Victimizations in Brazil: Using Representative Data From the 2019 National Health Survey

Using representative data from the 2019 National Health Survey (PNS-2019), we aim to investigate whether violent physical and sexual victimization differs by sexual orientation in Brazil. This was a cross-sectional study using data from a nationwide household-based survey. The PNS sample was selected with a three-stage cluster sampling. Prevalence of individuals aged 18 to 64 years who had suffered physical violence in the previous 12 months and 95% confidence intervals (CI) were estimated according to sex and sexual orientation. Multivariate logistic regression models were used with physical violence in the previous 12 months as the outcome and self-declared sexual orientation, sociodemographic characteristics, and age of sexual initiation as independent variables. Odds-ratios (OR) were estimated to test associations with the independent variables. The same statistical procedures were used for analyzing lifetime sexual violence. Among the 70,361 participants, 2.2% of men and 2.0% of women self-declared to be homosexual/bisexual. Among homosexual/bisexual men and women, 13% and 16%, respectively, have suffered physical violence in the previous 12 months. Regarding lifetime sexual violence, prevalence was 6.4% among homosexual/bisexual men, with OR = 9.1 (95% CI [5.7, 14.4]) in comparison to heterosexual men. Among homosexual/bisexual women, prevalence reached 11.5%, with OR = 2.4 (95% CI [1.7, 3.4]) in comparison to heterosexual women. After controlling for sexual orientation, the greatest odds of suffering physical violence in the previous 12 months were found among young people, non-white, starting sexual activity <15 years old, and poor education. The risk of women suffering lifetime sexual violence was seven times greater than that of men (OR = 7.30; 95% CI [6.05, 8.80]). The findings indicate a complex scenario in which sex, sexual orientation, skin color, and poor education interact in violent victimization and highlights the insufficiency of public policies in implementing effective actions focused on overcoming the homophobic prejudice that persists in Brazilian society.

Stroke in Brazil: prevalence, activity limitations, access to healthcare, and physiotherapeutic treatment

BACKGROUND

 Stroke remains a public health problem, reported as the third cause of disability. Among survivors, the ability to perform usual daily activities may be reduced, requiring rehabilitation.

OBJECTIVE

 To investigate the prevalence of self-reported stroke, the accessibility of healthcare, and the degree and percentage of patients with limitations in usual activities who are unassisted by physiotherapeutic treatment in different regions of the country.

METHODS

 This cross-sectional study was conducted using data from the 2019 National Health Survey. Participants aged 15 years or older from all five geographic regions of Brazil who reported a diagnosis of stroke were included. The data were analyzed using sample weighting and expressed as estimates along with a 95% confidence interval (CI).

RESULTS

 The national prevalence of self-reported stroke in Brazil was 1.9% (95%CI 1.7-2.0), equivalent to 1,975 individuals with diagnosis. Of these, 50.2% reported limitations in their daily activities, and more than half (54.6%) had regular follow-ups with healthcare professionals. However, only 24.6% reported having access to rehabilitation, while 73.4% of individuals with activity limitations received no physiotherapeutic treatment.

CONCLUSION

 The prevalence of' self-reported stroke in the Brazilian population was 1.9%, with more than half experiencing limitations in their activities. While more than half of the stroke patients underwent follow-ups from a health professional, only ¼ of them reported having access to rehabilitation. Government interventions are necessary to ensure effective access to healthcare, including rehabilitation for the Brazilian population.

Newborn pulse oximetry screening coverage in a nationwide complex survey sample: An assessment of a congenital heart disease early detection program at the regional level in Brazil

OBJECTIVES

To estimate the coverage of newborn pulse oximetry screening (POS) in Brazil, as well as identifies associated factors and the proportion of positive screening results.

METHODS

Coverage was estimated based on the most recent National Health Survey (2019). Adjusted marginal prevalence ratios were estimated via poisson regression model with robust variance.

RESULTS

The POS coverage was 66.3 % (95 %CI: 65.5-67.1; N = 3,140,023) and was higher in children born in privately funded hospitals (PFHs) than in the Unified Health System (SUS): 78.1 % (76.7-79.5) versus 61.1 % (60.2-62.1). In the North region, the POS coverage in PFHs (64.9 %, 59.7-70.1) was lower than that in the South (82.5 %, 79.4-85.6) and the Southeast (81.5 %, 79.3-83.6); it was even lower in SUS in the North (44.0 %; 42.4-45.6). After a federal ordinance providing financial resources to postscreening diagnostic, the screening coverage in SUS increased from 57.6 % (56.2-59.1) to 64.6 % (63.3-65.9). The proportion of positive screening tests was 9.2 % (8.9-9.5) in SUS and 7.8 % (7.3-8.3) in PFHs, of which 40.8 % (40.5-41.1) underwent complementary exams in SUS and 57.2 % (56.7-57.7) in PFHs. In the multivariate model, the main independent predictors of POS were the coverage of other newborn screening tests.

CONCLUSIONS

Inequalities were found between major regions and healthcare systems. Government financial incentives have reduced this inequality, although the percentage of postscreening complementary exams remains insufficient and unequal. The main independent predictors of screening prevalence were those related to the organization of health services.

Prevalence of disability and associated functional limitations among older adults in Brazil

INTRODUCTION

Disabilities are a serious public health, social and human rights issue. Few studies address the relationship between disabilities and functioning among older adults. The study aimed to estimate the prevalence of disability and its' association with comorbidities and functional limitations in Brazilian elderly individuals.

METHODS

Data from the National Health Survey-PNS 2019 was used. Prevalence rates with its corresponding 95% confidence intervals (CI) were estimated for variables of interest. Chi-squared tests and multiple logistic regression were conducted to investigate associations and estimate crude and adjusted odds ratios (OR) using Stata 17.0 software. The critical value (p<0.05) was considered.

RESULTS

The overall prevalence of disability was 58.3% (95% CI 57.2-59.4). Moderate/severe disabilities accounted for 24.1 (95% CI 23.1-25.1) and was high among elderly people females (27.9%, 95% CI 26.5-29.3), unemployed (28.4%, 95% CI 27.3-29.6), with an income of up to one minimum wage (30.6%, 95% CI 29.1-32.2), lower education (28.7%, 95% CI 27.5-29.9) and not married (28.5%, 95% CI 27.1-29.9). Crude odds ratios of having functional limitations were 4.5 times higher among individuals with three or more comorbidities, and 32.5 times higher among those with two or more disabilities, compared to those without these conditions.

CONCLUSION

Having a disability is an important predictor of functional limitations, especially among women, and people with lower income and education. To address this problem, public health policies such as encouraging physical activity among the elderly in Brazil should be implemented.

Social support and elder mistreatment in Brazil: exploring relationships and moderating effects

Prior literature has demonstrated a negative association between social support and elder mistreatment. Furthermore, social support may moderate the negative relationship between health-related indicators and elder mistreatment. This study is the first to investigate these assertions in Brazil using nationally representative data. We employ the 2019 National Health Survey and a series of binary logistic regressions. Overall, increased social support from stronger ties, like family and close friends, reduces the likelihood of elder mistreatment. However, increased participation in broader and more distant social networks and circles of sociability may increase the risk of mistreatment. Moreover, the negative relationship between health-related indicators and elder mistreatment is partially moderated by increased social support. While findings on other support dimensions vary, family support appears crucial in mitigating elder mistreatment. This study contributes by underscoring the intricate interplay of social support, health, and mistreatment, advocating for family-centered interventions to improve elder well-being in Brazil.

Multimorbidity patterns and socioeconomic conditions: Association with functional limitations in older adults

This study evaluated the association between multimorbidity patterns and socioeconomic conditions with functional limitation in individuals aged 60 years or older from the State of Minas Gerais, Brazil. This was a cross-sectional study with data from the last National Health Survey. Dependent variables were functional limitations in basic (BADL) and instrumental activities of daily living (IADL). The independent variables were multimorbidity patterns and socioeconomic conditions. Multimorbidity patterns were defined using an exploratory factor analysis. The association between multimorbidity patterns and dependent variables was tested using logistic regression models adjusted for covariates. Multimorbidity patterns were associated with limitations in BADL and IADL, except for the metabolic profile for IADL. Individuals with higher income had lower chances of being limited in BADL. Older adults with a higher level of education and income had lower chances of limitation in IADL. Multimorbidity patterns and socioeconomic conditions were associated with limitations in BADL and IADL.

Racial Disparities in Foot Examination among People with Diabetes in Brazil: A Nationwide Survey, 2019

Objective

To assess the absence of diabetic foot examination in Brazil and how ethnicity affected this outcome.

Design

This is an analysis of a nationwide survey held in Brazil in 2019. Participants with diabetes and that were 15 years of age or older were eligible for inclusion in the analysis. Adjusted Poisson regression with robust variance was used to calculate prevalence ratios (PRs) and 95% confidence intervals (95% CIs) of never having had the foot examined, with separate models according to ethnicity. Stata 14.2 was used for all calculations.

Results

We included 6216 individuals with diabetes; 52.1% (95%CI: 50.0%-54.2%) reported never having had their feet examined by a health care professional and 61% self-declared as Black (Black and Brown [Brazilian mixed race]). A higher frequency of negligence was observed among Black individuals (55.3%; 52.5%-58.1%) than among White individuals (48.2%; 45.0%-51.5%). Negligence was higher between 15- to 39-year-old participants (PR = 1.34, 1.14-1.57), lower educational level (PR = 1.37, 1.13-1.65), higher alcohol consumption (PR = 1.18, 1.06-1.31), fair health status (PR = 1.11, 1.01-1.21), and diabetes diagnosis of up to 10 years (PR = 1.42, 1.28-1.57). Among Blacks, tobacco use and other factors increased the frequency of the outcome, whereas participation in the Brazilian Unified Health System primary care program was a protection factor (P<.05).

Conclusion

Black Brazilians with diabetes had higher negligence of foot examination by health care professionals. Strengthening primary care would help mitigate systemic racism in Brazil.

Prevalence of depressive symptoms among young adults in Brazil: Results of the 2013 and 2019 editions of the National Health Survey

OBJECTIVE

To estimate the prevalence of depressive symptoms in the population aged 18 to 24, according to socioeconomic and demographic aspects in Brazil, comparing its evolution between 2013 and 2019.

METHODS

Cross-sectional study carried out with secondary data obtained from National Health Survey 2013 and 2019. It were included 7,823 young adulthood (aged 18 to 24) from 2013 and 8,047 from 2019. The instrument used to assess depression was the Patient Health Questionnaire-9 (PHQ-9). All estimates included population weights and complex sampling.

RESULTS

The prevalence of depression almost doubled: 10.9% (95%CI 9.6-12.2) in 2019, compared to 5.6% (95%CI 4.8-6.4) in 2013, an absolute difference of 5.3% (4.5-6.0) greater. Women were the most affected in both surveys, with an increase between 2013 (8.3%; 95%CI 6.9-9.6) and 2019 (15.6%; 95%CI 13.5-17.6) higher than that of men (2013: 2.9%; 95%CI 2.0-3.8 and 2019: 6.2%; 95%CI 4.7-7.7). In both sexes, the pattern of increase was greater for the groups aged 18 to 20, not participating in religious activities, who were at the lowest levels of education and income, who lived with two or three or more people, who lived in the Northeast, Southeast, capitals and metropolitan areas of the country.

CONCLUSION

There was a significant increase in the prevalence of depressive symptoms over the six years between the two surveys. However, this increase did not occur homogeneously among the characteristics analyzed, indicating population groups and locations in Brazil where the presence of these symptoms increased most in the period.

Decrease in Socioeconomic Disparities in Self-Rated Oral Health among Brazilian Adults between 2013 and 2019: Results from the National Health Survey

This cross-sectional study assessed the magnitude of inequalities in self-rated oral health (SROH) among different socioeconomic groups in Brazil. Secondary data from interviews with a sample of adults (≥18 years) from the national health survey 2013 (n = 64,308) and 2019 (n = 88,531) were analyzed. Positive SROH was considered when participants selected the good or very good options. Socioeconomic indicators were monthly household income and years of education. The magnitude of inequalities among socioeconomic groups was estimated using the Slope (SII) and Relative Index of Inequality (RII). Interaction term assessed changes in SII/RII over time. Estimates were adjusted for sex and age. The prevalence of SROH was 67.50% in 2013 and 69.68% in 2019. Individuals with lower socioeconomic indicators had a lower prevalence of positive SROH. Significant reductions in the magnitude of the education-based RII between 2013 (1.58) and 2019 (1.48) in Brazil, as well as in north (1.70; 1.45) and northeast (1.50; 1.41) regions and reduction in the income-based RII in the north (1.71; 1.51) were observed. Socioeconomic inequalities in SROH persist across different Brazilian regions, although there was a reduction in disparities among education groups in 2019 compared with 2013. The findings of this study suggest that equitable Brazilian oral health policies may have contributed to reducing SROH inequality over time.

Do movement behaviours influence the association between early menarche and depression symptoms among Brazilian adolescents?

Early menarche has been associated with adverse health outcomes, such as depressive symptoms. Discovering effect modifiers across these conditions in the pediatric population is a constant challenge. We tested whether movement behaviours modified the effect of the association between early menarche and depression symptoms among adolescents. This cross-sectional study included 2031 females aged 15-19 years across all Brazilian geographic regions. Data were collected using a self-administered questionnaire; 30.5% (n = 620) reported having experienced menarche before age 12 years (i.e., early menarche). We used the Patient Health Questionnaire (PHQ-9) to evaluate depressive symptoms. Accruing any moderate-vigorous physical activity during leisure time, limited recreational screen time, and having good sleep quality were the exposures investigated. Adolescents who experienced early menarche and met one (B: -4.45, 95% CI: (-5.38, -3.51)), two (B: -6.07 (-7.02, -5.12)), or three (B: -6.49 (-7.76, -5.21)), and adolescents who experienced not early menarche and met one (B: -5.33 (-6.20; -4.46)), two (B: -6.12 (-6.99; -5.24)), or three (B: -6.27 (-7.30; -5.24)) of the movement behaviour targets had lower PHQ-9 scores for depression symptoms than adolescents who experienced early menarche and did not meet any of the movement behaviours. The disparities in depressive symptoms among the adolescents (early menarche vs. not early menarche) who adhered to all three target behaviours were not statistically significant (B: 0.41 (-0.19; 1.01)). Adherence to movement behaviours modified the effect of the association between early menarche and depression symptoms.

Sedentary Behavior, Obesity, and Disabilities in Community-Dwelling Older Adults: Analysis of the Brazilian National Health Survey 2019

Research suggests that sedentary behavior (SB) and obesity are associated with disabilities in basic activities (BADL) and instrumental (IADL) activities of daily living. However, there is a lack of studies investigating this association in community-dwelling older adults. Thus, the aim of this study was to investigate the association between different SB typologies, isolated and in conjunction with obesity, and their associations with BADL and IADL disabilities in community-dwelling Brazilian older adults. This was a cross-sectional study using data from older adults (≥60 years) who participated in the Brazilian National Health Survey (2019). The exposures were obesity (BMI > 27 kg/m2) and the amount of time spent daily on SB watching television (SB TV < 3 and ≥3 h/day) and engaging in leisure activities (SB leisure < 3 and ≥3 h/day), analyzed both separately and jointly. The outcomes were BADL and IADL disabilities. The main results showed that isolated SB TV ≥ 3 h/day (OR: 1.26; 95% CI: 1.14; 1.39) and SB TV ≥ 3 h/day combined with obesity (OR: 1.55; 95% CI: 1.37; 1.75) increased the odds of BADL and IADL disabilities. Obesity alone (OR: 1.21; 95% CI: 1.07; 1.36) increased only the odds of BADL disabilities. Moreover, SB leisure ≥ 3 h/day without obesity reduced the odds of IADL disabilities (OR: 0.56; 95% CI: 0.41; 0.76). Ideally, older adults should be encouraged to prevent obesity, reduce excessive periods spent in SB watching TV, and increase the daily periods spent in leisure activities, thus minimizing the likelihood of disabilities in functional activities.

Access to medicines, the Unified Health System, and intersectional injustices

OBJECTIVE

To estimate the prevalence of general and public access to prescription drugs in the Brazilian population aged 15 or older in 2019, and to identify inequities in access, according to intersections of gender, color/race, socioeconomic level, and territory.

METHODS

We analyzed data from the 2019 National Health Survey with respondents aged 15 years or older who had been prescribed a medication in a healthcare service in the two weeks prior to the interview (n = 19,819). The outcome variable was access to medicines, subdivided into general access (public, private and mixed), public access (via the Unified Health System - SUS) for those treated by the SUS, and public access (via the SUS) for those not treated by the SUS. The study's independent variables were used to represent axes of marginalization: gender, color/race, socioeconomic level, and territory. The prevalence of general and public access in the different groups analyzed was calculated and the association of the outcomes with the aforementioned axes was estimated with odds ratios (OR) using logistic regression models.

RESULTS

There was a high prevalence of general access (84.9%), when all sources of access were considered, favoring more privileged segments of the population, such as men, white, and those of high socioeconomic status. When only the medicines prescribed in the SUS were considered, there was a low prevalence (30.4% access) that otherwise benefited marginalized population segments, such as women, black, and people from low socioeconomic backgrounds.

CONCLUSIONS

Access to medicines through the SUS proves to be an instrument for combating intersectional inequities, lending credence to the idea that the SUS is an efficient public policy for promoting social justice.

Exploring Maternal Socio-Demographic Factors Shaping Children's Dietary Patterns in Brazil: Results from the 2019 National Health Survey

This study aimed to identify the dietary patterns of Brazilian children aged 6-23 months and to investigate their association with maternal socio-demographic factors. Data from the 2019 Brazilian National Health Survey were used in this cross-sectional study. Mothers of 1616 children aged 6-23 months reported on their children's dietary intake. Dietary patterns were identified using principal component analysis, and their associations with maternal socio-demographic characteristics were assessed using linear regression models. The first consisted of healthy patterns and the second, unhealthy ones. Linear regression showed that adherence to a healthy dietary pattern was higher among children of mothers who were older (β = 0.02, p = 0.01), had more years of education (β = 0.49, p = 0.04), reported living with a partner (β = 0.29, p = 0.01), and resided in an urban area (β = 0.35, p = 0.01). Conversely, adherence to the unhealthy pattern was positively associated with mothers who declared themselves as black or brown (β = 0.25, p = 0.03). Our results show that older mothers with higher levels of education and paid work and who live with a partner are more likely to contribute to their children's healthy eating patterns. We conclude that socio-demographic factors may influence the quality of the food offered to children. Nevertheless, advocating for public policies promoting nutritious complementary diets emphasising fresh and minimally processed foods remains crucial for children whose mothers do not possess these favourable socio-demographic characteristics.

Validation of self-reported measures of nutritional status: a study based on the PNS 2019

The aim of this study was to analyze the validity of self-reported anthropometric measurements (weight and height) for classifying the nutritional status of Brazilian adults and elderly people using data from the 2019 National Health Survey (PNS). The PNS sample is made up of permanent private households from all of Brazil's federative units and this is a cross-sectional study in which 6,571 records were identified with measured and reported data, with no missing data for one variable being identified when in the presence of another. Validation was carried out with 6,381 data after removing atypical data. The variables used for stratification were: gender, age, race/color, schooling, and income, and the weighted Kappa Coefficient and the Intraclass Correlation Coefficient (ICC) were used to analyze agreement between the nutritional status categories. Accuracy was analyzed based on sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). For construct validity, a Poisson regression was performed for each outcome (measured and self-reported), with the independent variables "gender", "color/race", "schooling", and "family income". All the analyses showed positive results for validation. There was greater reproducibility among adults (18 to 59 years old) compared to the elderly and among men compared to women. This validation indicates a concrete possibility of carrying out an association of observational studies using reported nutritional status as the outcome variable, as an efficient strategy which could minimize the operational difficulties often encountered.

Estimated reduction in obesity prevalence and costs of a 20% and 30% ad valorem excise tax to sugar-sweetened beverages in Brazil: A modeling study

BACKGROUND

The consumption of sugar-sweetened beverages (SSBs) is associated with obesity, metabolic diseases, and incremental healthcare costs. Given their health consequences, the World Health Organization (WHO) recommended that countries implement taxes on SSB. Over the last 10 years, obesity prevalence has almost doubled in Brazil, yet, in 2016, the Brazilian government cut the existing federal SSB taxes to their current 4%. Since 2022, a bill to impose a 20% tax on SSB has been under discussion in the Brazilian Senate. To simulate the potential impact of increasing taxes on SSB in Brazil, we aimed to estimate the price-elasticity of SSB and the potential impact of a new 20% or 30% excise SSB tax on consumption, obesity prevalence, and cost savings.

METHODS AND FINDINGS

Using household purchases data from the Brazilian Household Budget Survey (POF) from 2017/2018, we estimated constant elasticity regressions. We used a log-log specification by income level for all beverage categories: (1) sugar-sweetened beverages; (2) alcoholic beverages; (3) unsweetened beverages; and (4) low-calorie or artificially sweetened beverages. We estimated the adult nationwide baseline intake for each beverage category using 24-h dietary recall data collected in 2017/2018. Taking group one as the taxed beverages, we applied the price and cross-price elasticities to the baseline intake data, we obtained changes in caloric intake. The caloric reduction was introduced into an individual dynamic model to estimate changes in weight and obesity prevalence. No benefits on cost savings were modeled during the first 3 years of intervention to account for the time lag in obesity cases to reduce costs. We multiplied the reduction in obesity cases during 7 years by the obesity costs per capita to predict the costs savings attributable to the sweetened beverage tax. SSB price elasticities were higher among the lowest tertile of income (-1.24) than in the highest income tertile (-1.13), and cross-price elasticities suggest SSB were weakly substituted by milk, water, and 100% fruit juices. We estimated a caloric change of -17.3 kcal/day/person under a 20% excise tax and -25.9 kcal/day/person under a 30% tax. Ten years after implementation, a 20% tax is expected to reduce obesity prevalence by 6.7%; 9.1% for a 30% tax. These reductions translate into a -2.8 million and -3.8 million obesity cases for a 20% and 30% tax, respectively, and a reduction of $US 13.3 billion and $US 17.9 billion in obesity costs over 10 years for a 20% and 30% tax, respectively. Study limitations include using a quantile distribution method to adjust self-reported baseline weight and height, which could be insufficient to correct for reporting bias; also, weight, height, and physical activity were assumed to be steady over time.

CONCLUSIONS

Adding a 20% to 30% excise tax on top of Brazil's current federal tax could help to reduce the consumption of ultra-processed beverages, empty calories, and body weight while avoiding large health-related costs. Given the recent cuts to SSB taxes in Brazil, a program to revise and implement excise taxes could prove beneficial for the Brazilian population.

Using Respondent-Driven Sampling (RDS) to Identify the Healthcare Needs among Women of Reproductive Age Who Migrated from Venezuela to Brazil, 2018-2021

In 2021, an RDS survey was conducted among Venezuelan migrant women of reproductive age who migrated to two Brazilian cities (Manaus and Boa Vista) from 2018 to 2021. To start the RDS recruitment, we chose seeds non-randomly in both cities. The study variables were age, educational level, self-rated health, pregnancy, migratory status and use of health services. We estimated the prevalence, confidence intervals and homophily effects by variable category. We used a multivariate logistic regression model to identify the main factors associated with healthcare use. A total of 761 women were recruited in Manaus and 1268 in Boa Vista. Manaus showed more irregular migrants than Boa Vista. The main reasons for using health services were as follows: illness, disease prevention and prenatal care. The logistic regression model showed the use of health services was associated with educational level and healthcare needs but not with migratory status. The social inclusion of Venezuelan migrants is extremely relevant, although many challenges must be overcome. The strategy of the Brazilian Federal Government for providing humanitarian assistance to Venezuelan migrants should be expanded to include and facilitate their integration into labor markets, access to healthcare and education, benefiting both migrants and the Brazilian people by reducing social inequality.

Study of machine learning techniques for outcome assessment of leptospirosis patients

Leptospirosis is a global disease that impacts people worldwide, particularly in humid and tropical regions, and is associated with significant socio-economic deficiencies. Its symptoms are often confused with other syndromes, which can compromise clinical diagnosis and the failure to carry out specific laboratory tests. In this respect, this paper presents a study of three algorithms (Decision Tree, Random Forest and Adaboost) for predicting the outcome (cure or death) of individuals with leptospirosis. Using the records contained in the government National System of Aggressions and Notification (SINAN, in portuguese) from 2007 to 2017, for the state of Pará, Brazil, where the temporal attributes of health care, symptoms (headache, vomiting, jaundice, calf pain) and clinical evolution (renal failure and respiratory changes) were used. In the performance evaluation of the selected models, it was observed that the Random Forest exhibited an accuracy of 90.81% for the training dataset, considering the attributes of experiment 8, and the Decision Tree presented an accuracy of 74.29 for the validation database. So, this result considers the best attributes pointed out by experiment 10: time first symptoms medical attention, time first symptoms ELISA sample collection, medical attention hospital admission time, headache, calf pain, vomiting, jaundice, renal insufficiency, and respiratory alterations. The contribution of this article is the confirmation that artificial intelligence, using the Decision Tree model algorithm, depicting the best choice as the final model to be used in future data for the prediction of human leptospirosis cases, helping in the diagnosis and course of the disease, aiming to avoid the evolution to death.

The Role of Hypogonadism in the Body Composition of Obese Men in the Preoperative Period of Bariatric Surgery

OBJECTIVE

To describe clinical characteristics, hormonal profile and body composition of obese men in preoperative of bariatric surgery.

METHODS

Cross-sectional, population-based study. Patients evaluated from June 2019 to December 2021 in 2 obesity referral centers. Patients underwent clinical evaluation, androgen deficiency screening using Androgen Deficiency in the Aging Male questionnaire, hormonal profile and body composition assessment through body mass index (BMI), body fat percentage (FM-%) and mass (FM-kg) measured by electrical bioimpedance and dual energy x-ray absorptiometry. To characterize hypogonadism, 2 cut-off points were considered: TT <264 ng/dL and TT <164 ng/dL.

RESULTS

Thirty patients were included, mean age 35.6 ± 8.8 years, mean weight 129.4 ± 14.0 kg and mean BMI 42.3 ± 4.7 kg/m2. Dyslipidemia was the most prevalent comorbidity. Considering TT <264 ng/dL, 22 patients (73%) had hypogonadism. The mean TT in hypogonadal men was 198.9 + 68.7 ng/dL and in eugonadal men 357.0 + 59.5 ng/dl (P < .001). Using TT <164 ng/dL, 7 patients (23%) had hypogonadism. The mean TT in hypogonadal patients was 116.6 + 28.9 ng/dL and in eugonadal patients 279.0 + 75.0 ng/dL (P < .001). In Androgen Deficiency in the Aging Male questionnaire, 93.3% had positive screening, with no significant difference between groups. There was no statistically significant difference in body composition between groups when using TT <264 ng/dL as the hypogonadism cutoff. Considering hypogonadism TT <164 ng/dL, hypogonadal patients had significantly higher values of weight (139.0 × 126.5 kg P = .036), BMI (46.1 × 41.2 kg/m2P = .014), FM-% (48.0 × 42.8% P = .010) and FM-kg (66.3 × 53.9 kg P = .007) than eugonadal patients.

CONCLUSION

Hypogonadism was identified in at least 23% of patients. Considering TT below the lower limit of normality for characterization of hypogonadism, we identified a significant worsening in body composition parameters.

What is the burden of multimorbidity and the factors associated with its occurrence in elderly Brazilians?

OBJECTIVE

To estimate the prevalence of multimorbidity in elderly people and its association with sociodemographic characteristics, lifestyle, and anthropometry.

METHODS

This was a cross-sectional study using data from the National Health Survey, 2019. A total of 22,728 elderly individuals from all 27 Brazilian states were randomly selected. Poisson regression models with robust variance were employed, and a significance level of 5% was adopted.

RESULTS

The prevalence of multimorbidity was 51.6% (95% CI: 50.4-52.7), with the highest estimates observed in the South and Southeast. Multimorbidity was associated with being female (aPR = 1.33; 95% CI: 1.27-1.39), being 80 years old or older (aPR = 1.12; 95% CI: 1.05-1.19), having low education (aPR = 1.16; 95% CI: 1.07-1.25), past cigarette use (aPR = 1.16; 95% CI: 1.11-1.21), insufficient physical activity (aPR = 1.13; 95% CI: 1.06-1.21), and screen use for 3 hours or more per day (aPR = 1.13; 95% CI: 1.08-1.18).

CONCLUSION

Multimorbidity affects more than half of the elderly population in Brazil and is associated with social, demographic, and behavioral factors.

Social and functional inclusion of an undergraduate student with unilateral upper limb agenesis: a case study

INTRODUCTION

The inclusion of health professionals who have some type of disability brings benefits, such as the increase in empathy that facilitates the relationship with patients. In this work, we present a case study on the inclusion of an undergraduate Dentistry student with upper limb agenesis.

PURPOSE

In order to improve the quality of life for people with upper limb agenesis, it is urgent to establish inclusion strategies in the educational field. This process included the use of assistive technologies to allow the manipulation of instruments used in the practice of dental clinical activities, enabling future Dentists with upper limb agenesis to have an equal education in relation to their academic peers.

CASE SELECTION

The case study presented in this work consists of the follow-up of G., a 23-year-old female Dentistry student. The developed adaptations were made using a low-temperature thermoplastic. The expert team that participated in this process was formed by three occupational therapists and three Dentistry professors. The process included several stages, being the last one the integration, in which training sessions were performed.

OUTCOMES

The process was accessed using two main tools: quantitative questionnaires and qualitative interviews. After the proposed intervention, the volunteer presented a gradual evolution in her occupational performance with the use of most adaptations, promoting her functional training.

DISCUSSIONS

Most adaptations allowed G. to perform the activities satisfactorily, with the precision inherent to these tasks, even with little training time.

CONCLUSIONS

This case study demonstrates the high applicability of the proposed technologies.

Occupational inequalities and gender differences: work accidents, Brazil, 2019

OBJECTIVE

To analyze the distribution and association of sociodemographic and occupational factors with self-reported work accidents (WA) in a representative sample of the Brazilian population, with emphasis on occupational class, and to examine gender differences in this distribution.

METHODS

A population-based cross-sectional study, using data from the 2019 National Health Survey (PNS), analyzed the responses of a sample of adults aged 18 or over. Factors associated with WA were investigated using binary logistic regression and hierarchical analysis using blocks (sociodemographic and occupational variables). The final model was adjusted by variables from all blocks, adopting a significance level of 5%. The values of odds ratios (OR) and respective confidence intervals were obtained.

RESULTS

Among the participants, 2.69% reported having suffered a WA, with a higher prevalence in men (3.37%; 95%CI 2.97-3.82%) than in women (1.86%; 95%CI 1.55-2.23%). The analysis identified that age group, night work, working hours, and exposure to occupational risks were associated with WA, with emphasis on gender differences. The class of manual workers, both qualified (ORwomen = 2.87; 95%CI 1.33-6.21 and ORmen = 2.46; 95%CI 1.37-4.40) and unskilled (ORwomen = 2.55; 95%CI 1.44-4.50 and ORmen = 3.70; 95%CI 1.95-7.03), had a higher chance of WA than the class of managers/professionals.

CONCLUSION

Occupational factors contributed significantly to the increase in the probability of WA for men and women, with greater magnitude among those positioned in the lower strata of the occupational structure. The results obtained are clues for working out WA prevention actions.

Race/Ethnicity Inequities in the Association Between Movement Behaviors and Suicidal Thoughts/Ideation Among Adolescents

OBJECTIVE

We aimed to analyze the associations between movement behaviors (physical activity, screen time, and sleep), independently and jointly, and suicidal thoughts/ideation among Brazilian adolescents according to race/ethnicity.

METHODS

This cross-sectional study surveyed 4,081 adolescents aged 15-19 years (49.9% females) across all Brazilian geographic regions. Data were collected using a self-administered questionnaire. Within the sample, 31.0% (n = 1,264) self-reported as White and 69.0% (n = 2,817) as Black. Adolescents who declared one or more times/week suicidal thoughts/ideation were considered as a risk group. Accruing moderate-to-vigorous physical activity during leisure time, reduced recreational screen time, and good sleep quality were the exposures investigated. We evaluated both additive and multiplicative interactions between race/ethnicity and movement behaviors. Binary logistic regression was used to estimate the odds ratio (OR), marginal means effects, and 95% confidence intervals (95% CIs).

RESULTS

Black adolescents who met 1 (OR: 0.34; [95% CI: 0.22-0.52]), 2 (OR: 0.17 [0.11-0.27]), or 3 (OR: 0.13 [0.07-0.26]), and White adolescents who met 1 (OR: 0.35 [0.21-0.57]), 2 (OR: 0.14 [0.08-0.26]), or 3 (OR: 0.11 [0.04-0.31]) of the movement behavior targets had lower odds of suicidal thoughts/ideation than Black adolescents who did not meet any of the movement behavior targets. Black adolescents who did not meet any of the movement behavior targets had higher suicidal thoughts/ideation odds than the other adolescent's groups.

CONCLUSIONS

We identified an inverse association between meeting individuals and combinations of movement behavior targets with suicidal thoughts/ideation. Among Black adolescents who did not meet any targets, these associations were more evident.

Prevalence and factors associated with driving under the influence of alcohol in Brazil

OBJECTIVES

To estimate the prevalence and factors associated with Driving Under the Influence of Alcohol (DUIA) among car drivers and motorcyclists in Brazil and to evaluate the association between DUIA and self-reported Road Traffic Injuries (RTIs) in these groups.

METHODS

A cross-sectional study was conducted using data from adults aged 18 or older who participated in the 2019 National Health Survey. Probability sampling was used to recruit participants, and data collection was carried out through home visits. Data from 31,246 car drivers and 21,896 motorcyclists were analyzed. Key indicators included the proportion (%) of car drivers who consumed alcohol and then drove in the past 12 months and the proportion (%) of motorcyclists who consumed alcohol and then drove in the past 12 months. Multiple Poisson regression was used to determine factors associated with DUIA and the association of this variable with RTIs in both groups.

RESULTS

DUIA prevalence was 9.4% (95% Confidence Interval [95% CI] = 8.8-10.0) among car drivers and 11.2% (95% CI = 10.4-12.1) among motorcyclists. Among car drivers, DUIA prevalence was higher in men, young adults, those without a spouse/partner, and lower in individuals with lower income and education level. Among motorcyclists, DUIA prevalence was higher in men, young adults, those living outside the capitals and metropolitan regions, and lower in individuals with lower income. DUIA increased the prevalence of self-reported RTIs in the previous 12 months among car drivers and motorcyclists.

CONCLUSIONS

A high prevalence of DUIA was evident among drivers, particularly motorcyclists. The DUIA was more prevalent among men and young adults. The DUIA was associated with an increased magnitude of self-reported RTIs among car drivers and motorcyclists. Despite the extensive legislation for zero tolerance toward DUIA in the country, actions need stricter enforcement.

A National Study on Psychological Violence in Brazil: Differences by Sex and Skin Color

Violence is a global public health problem that affects especially the most vulnerable people. The aim was to analyze the prevalence of psychological violence in the Brazilian population and inequalities according to sex and skin color. This was a cross-sectional study in which the database of the National Health Survey 2019 was used. Psychological violence was considered present when an individual answered yes to at least one of the five variables investigated: In the last 12 months, has anyone (a) offended you, humiliated you, or ridiculed you in front of other people?; (b) yelled at you or called you names?; (c) used social media or cell phones to threaten, offend, curse, or expose your images without your consent?; (d) threatened to hurt you or hurt someone important to you?; and (e) destroyed something of yours on purpose? The independent variable was skin color. The crude prevalence ratio (PR) was determined by Poisson regression. All analyses were stratified by sex. Of the 88,531 respondents, 41,662 were males and 46,869 were females. The prevalence of the presence of psychological violence was 19% in women and 15.6% in men. Men and women with black/brown/yellow/indigenous skin color were 20% and 15% more likely to suffer one or more items of psychological violence, respectively, than men and women with white skin color (PR = 1.20; 95% CI [1.11, 1.30] and PR = 1.15; 95% CI [1.08, 1.23]). Psychological violence occurred predominantly against females and individuals with black/brown/yellow/indigenous skin color. There were notable inequalities in the exposure to this type of violence that need to be considered when making plans to address this problem. The findings emphasize the relevance of constantly reviewing political and social constructions to promote a reduction of inequalities.

Prevalence of multimorbidity in Brazilian individuals: A population-based study

This study aimed to estimate the prevalence of multimorbidity in Brazilian individuals and its association with sociodemographic and lifestyle factors. This cross-sectional study used data from the National Health Survey conducted in 2019 with 88,531 Brazilian adults Multimorbidity is the presence of two or more non-communicable chronic diseases. Associated factors were assessed by calculating the prevalence ratio (PR) obtained using Poisson regression with robust variance. Multimorbidity was estimated in 29.9% (95%CI: 29.33% to 30.48%) of Brazilian individuals. In the multiple models, the prevalence was high in women (PR: 1.37; 95%CI: 1.32 to 1.42), individuals over 60 years (PR: 4.26; 95%CI: 3.87 to 4.69), non-employed (PR: 1.20; 95%CI: 1.15 to 1.26), individuals with obesity (PR: 1.49; 95%CI: 1.43 to 1.56), and smokers (PR: 1.24; 95%CI: 1.19 to 1.29). This study identified a high prevalence of multimorbidity and its association with sociodemographic and lifestyle factors. The monitoring of these outcomes may support the development of policies and services.

[Contextual characteristics and demand for health services among Brazilian adolescents: Brazilian National Health Survey, 2019]

This study aimed to describe the prevalence of demand for health services among Brazilian adolescents and to investigate its association with contextual characteristics of the territory. Study with data from the Brazilian National Health Survey, conducted in 2019, including 43,774 individuals aged from 10 to 19 years. Adolescent's information was obtained through a proxy resident of 18 years or more who answered for all the residents of the household. Poisson regression was used to assess the demand for health services according to geopolitical region, economic status, and type of municipality. The interaction of the health insurance was also evaluated in these associations. Of the total, 11.7% (95%CI: 11.1; 12.3) of the adolescents sought health services in the two weeks prior to the survey. Greater figures of demand were observed in the Southeast (PR = 1.32; 95%CI: 1.15; 1.52) and South regions (PR = 1.31; 95%CI: 1.13; 1.52) compared to the Northern Region of Brazil. Having a health insurance increased the demand for services by adolescents living in rural areas and in capitals and the municipalities of the Metropolitan Areas and/or Integrated Development Regions. The study showed a low prevalence of demand for health services among adolescents and contextual inequalities for the geopolitical region. Having a health insurance was an important marker to understand the disparities in the economic status and in the type of municipality.

Reported recommendations to address cardiovascular risk factors differ by socio-economic status in Brazil. Results from the Brazilian National Health Survey 2019

Background

Management of cardiovascular risk factors (high cholesterol, diabetes, and hypertension) should start by implementing a healthy lifestyle. Whereas lifestyle recommendations are provided irrespective of the patient's socio-economic status has not been recently assessed in the Brazilian population.

Aims

To assess the preventive measures against cardiovascular risk factors according to educational level and income in the Brazilian population.

Methods

Survey data of the 2019 Brazilian National Health Survey (PNS). The PNS is a nationwide household-based survey carried out by the Brazilian Ministry of Health. The PNS included face-to-face interviews and collected information on lifestyle management of high cholesterol, diabetes, and hypertension by a healthy diet, an adequate weight, exercise, and quitting smoking. The participant's educational level and income (in multiples of the basic salary per capita) was collected.

Results

Of the 88,052 participants included, 13,151 (14.9%), 6,986 (7.9%) and 22,516 (25.6%) reported being diagnosed with high cholesterol, diabetes, or hypertension, respectively. Dietary recommendations were the most frequently provided (94.5%, 94.6% and 88.1% for high cholesterol diabetes, and hypertension, respectively), while recommendations to quit smoking to current smokers were the least frequently provided (74.9%, 85.8% and 81.1% for high cholesterol, diabetes, and hypertension, respectively). After multivariable adjustment, participants with a higher educational level or a higher income had a higher likelihood of reporting receipt lifestyle recommendations for high cholesterol or hypertension, while no associations were found for most recommendations for diabetes.

Conclusion

Better-educated, wealthier Brazilians report receiving more lifestyle recommendations regarding high cholesterol and hypertension management more frequently than lower-educated or with low-income.

Lung Cancer Screening in Brazil Comparing the 2013 and 2021 USPSTF Guidelines

Importance

It is estimated that, from 2023 to 2025, lung cancer (LC) will be the second most frequent cancer in Brazil, but the country does not have an LC screening (LCS) policy.

Objective

To compare the number of individuals eligible for screening, 5-year preventable LC deaths, and years of life gained (YLG) if LC death is averted by LCS, considering 3 eligibility strategies by sociodemographic characteristics.

Design, Setting, and Participants

This comparative effectiveness research study assessed 3 LCS criteria by applying a modified version of the LC-Death Risk Assessment Tool (LCDRAT) and the LC-Risk Assessment Tool (LCRAT). Data are from the 2019 Brazilian National Household Survey. Participants included ever-smokers aged 50 to 80 years. Data analysis was performed from February to May 2023.

Exposures

Exposures included ever-smokers aged 50 to 80 years, US Preventive Services Task Force (USPSTF) 2013 guidelines (ever-smokers aged 55 to 80 years with ≥30 pack-years and <15 years since cessation), and USPSTF 2021 guidelines (ever-smokers aged 50 to 80 years with 20 pack-years and <15 years since cessation).

Main Outcomes and Measures

The primary outcomes were the numbers of individuals eligible for LCS, the 5-year preventable deaths attributable to LC, and the number of YLGs if death due to LC was averted by LCS.

Results

In Brazil, the eligible population for LCS was 27 280 920 ever-smokers aged 50 to 80 years (13 387 552 female [49.1%]; 13 249 531 [48.6%] aged 50-60 years; 394 994 Asian or Indigenous [1.4%]; 3 111 676 Black [11.4%]; 10 942 640 Pardo [40.1%]; 12 830 904 White [47.0%]; 12 428 536 [45.6%] with an incomplete middle school education; and 12 860 132 [47.1%] living in the Southeast region); 5 144 322 individuals met the USPSTF 2013 criteria for LCS (2 090 636 female [40.6%]; 2 290 219 [44.5%] aged 61-70 years; 66 430 Asian or Indigenous [1.3%]; 491 527 Black [9.6%]; 2 073 836 Pardo [40.3%]; 2 512 529 [48.8%] White; 2 436 221 [47.4%] with an incomplete middle school education; and 2 577 300 [50.1%] living in the Southeast region), and 8 380 279 individuals met the USPSTF 2021 LCS criteria (3 507 760 female [41.9%]; 4 352 740 [51.9%] aged 50-60 years; 119 925 Asian or Indigenous [1.4%]; 839 171 Black [10.0%]; 3 330 497 Pardo [39.7%]; 4 090 687 [48.8%] White; 4 022 784 [48.0%] with an incomplete middle school education; and 4 162 070 [49.7%] living in the Southeast region). The number needed to screen to prevent 1 death was 177 individuals according to the USPSTF 2013 criteria and 242 individuals according to the USPSTF 2021 criteria. The YLG was 23 for all ever-smokers, 19 for the USPSTF 2013 criteria, and 21 for the USPSTF 2021 criteria. Being Black, having less than a high school education, and living in the North and Northeast regions were associated with increased 5-year risk of LC death.

Conclusions and Relevance

In this comparative effectiveness study, USPSTF 2021 criteria were better than USPSTF 2013 in reducing disparities in LC death rates. Nonetheless, the risk of LC death remained unequal, and these results underscore the importance of identifying an appropriate approach for high-risk populations for LCS, considering the local epidemiological context.

Last dental visit and severity of tooth loss: a machine learning approach

The aims of the present study were to investigate last dental visit as a mediator in the relationship between socioeconomic status and lack of functional dentition/severe tooth loss and use a machine learning approach to predict those adults and elderly at higher risk of tooth loss. We analyzed data from a representative sample of 88,531 Brazilian individuals aged 18 and over. Tooth loss was the outcome by; (1) functional dentition and (2) severe tooth loss. Structural Equation models were used to find the time of last dental visit associated with the outcomes. Moreover, machine learning was used to train and test predictions to target individuals at higher risk for tooth loss. For 65,803 adults, more than two years of last dental visit was associated with lack of functional dentition. Age was the main contributor in the machine learning approach, with an AUC of 90%, accuracy of 90%, specificity of 97% and sensitivity of 38%. For elders, the last dental visit was associated with higher severe loss. Conclusions. More than two years of last dental visit appears to be associated with a severe loss and lack of functional dentition. The machine learning approach had a good performance to predict those individuals.

Is parenthood associated with self-rated health among women in Brazil?

BACKGROUND

Previous studies conducted in Europe and North America addressing the relationship between self-rated health and parenthood offer inconsistent results, with effects ranging from nonsignificant to significant and in opposite directions. The aim of the present study was to explore the relationship between parenthood and self-rated health (SRH) among women in Brazil (a country with strong inequalities) considering the time interval from the last delivery in the analyses, as proposed in previous studies set in Sweden.

METHODS

The study used data from cross-sectional National Health Surveys in Brazil conducted from 2013 to 2014 and 2019 to 2020 with selected groups of 20,046 and 25,100 women for whom complete data were available on the variables of interest. The primary outcome was self-rated health measured on a five-point scale. Partial proportional odds models were employed.

RESULTS

Compared to women that were not a parent, primiparous women whose delivery was within less than one year had a lower likelihood of worse SRH (OR (95% CI): 0.58-0.84 in 2013, and 0.64-0.94 in 2019), whereas multiparous women whose last delivery was more than one year earlier had greater likelihood of worse SRH (OR (95% CI): 1.08-1.27 in 2013, and 1.21-1.39 in 2019).

CONCLUSIONS

An association was found between parenthood and SRH among Brazilian women. Considering the epidemiological relevance of SRH, different aspects of parenthood concerning parity and time since the last delivery should be considered in further analyses.

Long working hours and self-rated health in the national Brazilian working population: gender and employment status differences, 2019

BACKGROUND

The regulation of working hours is governed by legal standards in formal employment. While the association between long working hours and various health outcomes has been extensively studied, there is limited evidence regarding Brazil. The objective of this study was to investigate the association among working hours, employment status, and self-rated health (SRH), taking into account differences between men and women in a national representative sample of the working population in Brazil.

METHODS

A cross-sectional study was conducted among a representative sample of 33,713 workers in Brazil to assess self-rated health (SRH). We examined the associations between working hours and employment status, categorizing working hours as standard (40-44 h per week) or long (> 44 h per week), and employment status as formal or informal. Logistic regression models were employed, adjusting for sociodemographic, occupational characteristics, and health behaviors. Probabilities of negative SRH were calculated for men and women in different exposure profiles. Results were stratified by gender, and 95% confidence intervals (CIs) were applied to the findings.

RESULTS

The prevalence of long working hours was higher among informal workers for both men and women. Adjusted odds ratio (AOR) results revealed that informal employment (AORwomen = 1.53; 95% CI: 1.13-2.07 and AORmen = 1.55; 95% CI: 1.22-1.96) and long working hours (AORwomen = 1.23; 95% CI: 1.06-1.43 and AORmen = 1.14; 95% CI: 1.00-1.30) were independently associated with negative SRH. Significant interactions between long working hours and informal employment were observed. Among individuals with the same exposure profile, women who engaged in long working hours had a higher probability of reporting negative SRH compared to men.

CONCLUSIONS

The results of this study are in line with the literature, as differences between men and women in the likelihood of negative self-rated health were observed. The adverse health effects underscore the importance of implementing intersectoral actions to inform the revision of regulations concerning weekly working hours and the expansion of informal employment in low- and middle-income countries.

Papanicolaou test in Brazil: analysis of the National Health Survey of 2013 and 2019

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.

Hospitalizations in Brazil according to National Health Survey estimates, 2013 and 2019

OBJECTIVE

To compare the profile and prevalence of hospitalizations in Brazil based on estimates from the National Health Survey (PNS), 2013 and 2019.

METHODS

A cross-sectional study that used data from the 2013 PNS and the 2019 PNS. The outcome was having been hospitalized for 24 hours or more in the last 12 months. We calculated the proportion of the population in different categories of age group, presence or absence of chronic diseases, and perception of health status. We estimated the total number of hospitalizations and the proportion corresponding to each category of age group, chronic disease, and perceived health status. We calculated the prevalence of hospitalization according to geographic, socioeconomic, and health conditions. We compared the estimates of two editions of the PNS using Student's t-test for independent samples. We considered significant differences when the p-value was less than 0.01. And finally, we compared hospitalization estimates with administrative data to assess data consistency.

RESULTS

We observed that the proportion of chronically ill people in the population increased from 15.04% to 31.48%. This group was responsible for 36.76% of the total number of hospitalizations in 2013 and 57.61% in 2019. The prevalence of hospitalizations increased significantly between the two surveys and the increases were higher in the Southeast region and among people who have private health insurance. A discrepancy was found between administrative data and survey estimates. Obstetric hospitalizations and health insurance hospitalizations were underestimated.

CONCLUSION

There was an increase in overall hospitalization rates in the period between the PNS 2013 and PNS 2019, especially among people with better access to health services. The hospitalization profile also changed-in the 2013 PNS, hospitalizations of people without chronic diseases predominated. This was reversed in PNS 2019.

[Contraceptive mix and factors associated with the type of method used by Brazilian women: a population-based cross-sectional study]

This study aims to describe the contraceptive mix and analyze the factors associated with the type of contraceptive used by Brazilian women of reproductive age. This is a cross-sectional, population-based study with data from 19,962 women aged 15 to 49 years. The outcomes were use and type of contraceptive, classified as: short-acting reversible contraceptives (SARC), long-acting (LARC), and permanent. The explanatory variables were characteristics of reproductive history, sociodemographic history, and access to health services. Multinomial logistic regression was used for odds ratio (OR) estimates, with SARC being the reference category. The analyses were performed in the Survey module of the Stata software, which considered the effect of the complex sampling plan of the 2019 Brazilian National Health Survey. The prevalence of contraceptive use was 83.7%. Of the total number of users, 72% used SARC, 23.2% permanent methods, and 4.8% LARC. Women with higher education, health insurance, who had deliveries, and who participated in reproductive planning groups had a higher chance of using LARC when compared with the use of SARC, while registration at the basic health unit was associated with a lower chance of use. Still, the higher the age and parity, in addition to living with the partner, the greater the chance of using permanent methods in relation to the use of SARC. Despite the high coverage of contraception, the contraceptive mix remains obsolete, with a predominance of the use of SARC. In addition, important inequalities in access were observed, with LARC being accessible only to women with better socioeconomic conditions, while permanent methods were associated with a profile of greater social vulnerability.

Physical Activity Levels in Leisure Time, Sociodemographic Characteristics, and Chronic Non-Communicable Diseases in Brazilian Older Adults: National Health Survey, 2019

Health interventions for elderly people must understand the association between physical activity, sociodemographic factors, and non-communicable diseases. This study aimed to verify the association between physical activity in leisure time, sociodemographic factors, and NCDs in Brazilian older people. This is a descriptive study, with a cross-sectional design, carried out using secondary data from the 2019 National Health Survey-Brazil. It used data from 23,144 subjects aged over 60 years. Statistical analyses included descriptive and quantile regression with cutoff points 0.25, 0.50 (Median), 0.75, and 0.90 to verify the association between the variables. The statistical software R version 4.1.3 was used. Older people aged between 60 and 79 years were highlighted up to the 50th quantile. Females showed lower values in all quantiles, with emphasis from quantile 50 onwards. Subjects who self-declared as "white" showed significant differences up to quantile 50, not indicating significant values from this cutoff point. Residents of the rural area had lower values than residents of the urban area in all quantiles, with emphasis starting from the median. For cardiovascular diseases, it was found that subjects who did not report having this type of disease had better results for the amount of physical activity during leisure time, especially from the 75th quantile. It was concluded that there is a direct relationship between time spent in leisure-time performing physical activity, sociodemographic variables, and NCDs. It is necessary to review and validate cutoff points according to each category viewed, which can favor the adjustment of interventions according to each population. Actions of this nature can favor adherence by groups of older people to the weekly practice of physical activity.

The mediating role of social capital in socioeconomic inequalities of oral health behaviours among Brazilian older adults

OBJECTIVES

Knowledge of the possible pathways linking socioeconomic status (SES) to oral health-related behaviours can improve the understanding of inequalities in oral health. Therefore, in this study, it was investigated whether social capital mediates the relationship between SES and oral health behaviours.

METHODS

Through a cross-sectional study, data were analysed from participants aged ≥60 years from the Brazilian National Health Survey 2019 (n = 21 575). Structural equation modelling was used to test the direct and indirect pathways from a latent variable for SES to a latent variable for oral health behaviours: daily flossing, toothbrushing frequency and the use of dental care services.

RESULTS

The maximum likelihood estimator was used for complex samples with robust standard errors, and the final model demonstrated an adequate fit. The findings demonstrated that a higher SES was directly associated with better oral health-related behaviours (standardized coefficient [SC]: 0.82; [90% CI: 0.78-0.85]) and indirectly via structural social capital (SC: 0.05; [90% CI: 0.02-0.07]). The total effect of SES on oral health-related behaviours was (SC: 0.87, [90% CI: 0.85-0.89]).

CONCLUSION

The findings demonstrate that structural social capital in older Brazilian adults might partly mediate the pathways to socioeconomic inequalities in oral health behaviours. However, there is a direct effect on oral health behaviours, reinforcing the hypothesis that SES is associated with oral health, based on paths that link income inequality to oral health.

Using Andersen's behavioural model to examine individual and contextual factors associated with dental service utilization in Brazil

OBJECTIVES

The study aimed to examine individual and contextual factors associated with the frequency of dental service utilization among adolescents, adults and older adults Brazilians.

METHODS

This cross-sectional study used secondary data from the Brazilian 2019 National Health Survey (94 114 individuals). The outcome 'when was your last dental appointment?' was categorized into three groups: up to 1 year, more than 1 year and never had a dental appointment. Andersen's behavioural model was used to select contextual and individual variables. Multinomial logistic regression analysis was performed to calculate the odds ratio (OR) and 95% confidence intervals (95% CI).

RESULTS

The following variables showed increased probability to the outcome had the last dental appointment more than 1 year ago: older adult, illiterate or incomplete primary school, and without private dental insurance. The outcome never had a dental appointment was significantly associated with illiterate (OR 26.65; 95% CI 17.63-40.29), male (OR 2.38; 95% CI 2.17-2.61), without private dental insurance (OR 5.20; 95% CI 3.48-7.76), self-rated oral health as bad or very bad (OR 2.67; 95% CI 2.31-3.09), household not enrolled in primary care teams (OR 1.29; 95% CI 1.11-1.49), household in a rural area (OR 1.86; 95% CI 1.69-2.05), high household crowding (OR 1.08; 95% CI 1.04-1.14) and low household income per capita (OR 0.99; 95% CI 0.99-0.99).

CONCLUSIONS

This study showed that contextual and individual factors induce inequity in dental appointments. Moreover, Andersen's behavioural model demonstrated inequitable access for dental services in Brazil, in which social structure and enabling characteristics, rather than the need for the service, determine who receives health care. Living in a household enrolled in primary care teams favoured regular dental appointments. Thus, these findings may help policymakers improve health access by expanding coverage of dental services in primary health care.

Doctors' recommendations and healthy lifestyle behaviors among individuals with hypertension in Brazil

Little is known about whether doctors' recommendations encourage healthy behaviors among individuals with hypertension in Brazil. This study examined the biological, social, and health factors related to doctor's recommendations and the associations between doctor's recommendations and healthy behaviors. The sample consisted of individuals with hypertension (N = 18,260) from Brazil's 2019 National Health Survey. The outcomes examined included smoking, drinking, diet, salt intake, physical activity, and doctor visits. Study findings indicated that more than 80% of people with hypertension in Brazil received doctors' recommendations to adhere to medical care and engage in healthy behaviors. Those who received recommendations were more likely to practice healthy eating and exercise regularly but also to be obese/overweight, smoke, and drink excessively. Nonetheless, the findings concerning diet and exercise suggest the value of doctors' recommendations for individuals with hypertension in Brazil.
