Evaluating the relationship between conditional cash transfer programme on preterm births: a retrospective longitudinal study using the 100 million Brazilian cohort.

BACKGROUND: Preterm births increase mortality and morbidity during childhood and later life, which is closely associated with poverty and the quality of prenatal care. Therefore, income redistribution and poverty reduction initiatives may be valuable in preventing this outcome. We assessed whether receipt of the Brazilian conditional cash transfer programme - Bolsa Familia Programme, the largest in the world - reduces the occurrence of preterm births, including their severity categories, and explored how this association differs according to prenatal care and the quality of Bolsa Familia Programme management. METHODS: A retrospective cohort study was performed involving the first live singleton births to mothersenrolled in the 100 Million Brazilian Cohort from 2004 to 2015, who had at least one child before cohort enrollment. Only the first birth during the cohort period was included, but born from 2012 onward. A deterministic linkage with the Bolsa Familia Programme payroll dataset and a similarity linkage with the Brazilian Live Birth Information System were performed. The exposed group consisted of newborns to mothers who received Bolsa Familia from conception to delivery. Our outcomes were infants born with a gestational age < 37 weeks: (i) all preterm births, (ii) moderate-to-late (32-36), (iii) severe (28-31), and (iv) extreme (< 28) preterm births compared to at-term newborns. We combined propensity score-based methods and weighted logistic regressions to compare newborns to mothers who did and did not receive Bolsa Familia, controlling for socioeconomic conditions. We also estimated these effects separately, according to the adequacy of prenatal care and the index of quality of Bolsa Familia Programme management. RESULTS: 1,031,053 infants were analyzed; 65.9% of the mothers were beneficiaries. Bolsa Familia Programme was not associated with all sets of preterm births, moderate-to-late, and severe preterm births, but was associated with a reduction in extreme preterm births (weighted OR: 0.69; 95%CI: 0.63-0.76). This reduction can also be observed among mothers receiving adequate prenatal care (weighted OR: 0.66; 95%CI: 0.59-0.74) and living in better Bolsa Familia management municipalities (weighted OR: 0.56; 95%CI: 0.43-0.74). CONCLUSIONS: An income transfer programme for pregnant women of low-socioeconomic status, conditional to attending prenatal care appointments, has been associated with a reduction in extremely preterm births. These programmes could be essential in achieving Sustainable Development Goals.

Conditional cash transfer program and child mortality: A cross-sectional analysis nested within the 100 Million Brazilian Cohort.

BACKGROUND: Brazil has made great progress in reducing child mortality over the past decades, and a parcel of this achievement has been credited to the Bolsa Família program (BFP). We examined the association between being a BFP beneficiary and child mortality (1-4 years of age), also examining how this association differs by maternal race/skin color, gestational age at birth (term versus preterm), municipality income level, and index of quality of BFP management. METHODS AND FINDINGS: This is a cross-sectional analysis nested within the 100 Million Brazilian Cohort, a population-based cohort primarily built from Brazil's Unified Registry for Social Programs (Cadastro Único). We analyzed data from 6,309,366 children under 5 years of age whose families enrolled between 2006 and 2015. Through deterministic linkage with the BFP payroll datasets, and similarity linkage with the Brazilian Mortality Information System, 4,858,253 children were identified as beneficiaries (77%) and 1,451,113 (23%) were not. Our analysis consisted of a combination of kernel matching and weighted logistic regressions. After kernel matching, 5,308,989 (84.1%) children were included in the final weighted logistic analysis, with 4,107,920 (77.4%) of those being beneficiaries and 1,201,069 (22.6%) not, with a total of 14,897 linked deaths. Overall, BFP participation was associated with a reduction in child mortality (weighted odds ratio [OR] = 0.83; 95% CI: 0.79 to 0.88; p < 0.001). This association was stronger for preterm children (weighted OR = 0.78; 95% CI: 0.68 to 0.90; p < 0.001), children of Black mothers (weighted OR = 0.74; 95% CI: 0.57 to 0.97; p < 0.001), children living in municipalities in the lowest income quintile (first quintile of municipal income: weighted OR = 0.72; 95% CI: 0.62 to 0.82; p < 0.001), and municipalities with better index of BFP management (5th quintile of the Decentralized Management Index: weighted OR = 0.76; 95% CI: 0.66 to 0.88; p < 0.001). The main limitation of our methodology is that our propensity score approach does not account for possible unmeasured confounders. Furthermore, sensitivity analysis showed that loss of nameless death records before linkage may have resulted in overestimation of the associations between BFP participation and mortality, with loss of statistical significance in municipalities with greater losses of data and change in the direction of the association in municipalities with no losses. CONCLUSIONS: In this study, we observed a significant association between BFP participation and child mortality in children aged 1-4 years and found that this association was stronger for children living in municipalities in the lowest quintile of wealth, in municipalities with better index of program management, and also in preterm children and children of Black mothers. These findings reinforce the evidence that programs like BFP, already proven effective in poverty reduction, have a great potential to improve child health and survival. Subgroup analysis revealed heterogeneous results, useful for policy improvement and better targeting of BFP.

Monitoring the progress of health-related sustainable development goals (SDGs) in Brazilian states using the Global Burden of Disease indicators.

BACKGROUND: Measuring the Global Burden of Disease (GBD) has been the key to verifying the evolution of health indicators worldwide. We analyse subnational GBD data for Brazil in order to monitor the performance of the Brazilian states in the last 28 years on their progress towards meeting the health-related SDGs. METHODS: As part of the GBD study, we assessed the 41 health-related indicators from the SDGs in Brazil at the subnational level for all the 26 Brazilian states and the Federal District from 1990 to 2017. The GBD group has rescaled all worldwide indicators from 0 to 100, assuming that for each one of them, the worst value among all countries and overtime is 0, and the best is 100. They also estimate the overall health-related SDG index as a function of all previously estimated health indicators and the SDI index (Socio-Demographic Index) as a function of per capita income, average schooling in the population aged 15 years or over, and total fertility rate under the age of 25 (TFU25). RESULTS: From 1990 to 2017, most subnational health-related SDGs, the SDG and SDI indexes improved considerable in most Brazilian states. The observed differences in SDG indicators within Brazilian states, including HIV incidence and health worker density, increased over time. In 2017, health-related indicators that achieved good results globally included the prevalence of child wasting, NTD, household air pollution, conflict mortality, skilled birth attendance, use of modern contraceptive methods, vaccine coverage, and health worker density, but poor results were observed for child overweight and homicide rates. The high rates of overweight, alcohol consumption, and smoking prevalence found in the historically richest regions (i.e., the South and Southeast), contrast with the high rates of tuberculosis, maternal, neonatal, and under-5 mortality and WASH-related mortality found in the poorer regions (i.e., the North and Northeast). CONCLUSIONS: The majority of Brazil's health-related SDG indicators have substantially improved over the past 28 years. However, inequalities in health among the Brazilian states and regions remain noticeable negatively affecting the Brazilian population, which can contribute to Brazil not achieving the SDG 2030 targets.

The behavioural constellation of deprivation: Compelling framework, messy reality.

Pepper & Nettle's (P&N's) argument is compelling, but apparently contradictory data are easily found. Associations between socioeconomic status (SES) and substance abuse are sometimes positive, the poor are sometimes eager to educate their children, and perceptions of local mortality risk can be so distorted as to constitute an implausible basis for contextually appropriate responding. These anomalies highlight the need for more psychological work.

Racial Disparities in Medication Use During Pregnancy: Results from the NISAMI Cohort.

Purpose: This study aimed to evaluate racial disparities in medication use and associated factors among pregnant women receiving prenatal care at Brazilian Unified Health System primary care health units in the northeast region. Patients and Methods: A total of 1058 pregnant women in the NISAMI Cohort were interviewed between June 2012 and February 2014. Medicines used during pregnancy were classified according to the Anatomical Therapeutic Chemical (ATC) classification system and ANVISA pregnancy risk categories. Prevalence ratios (crude and adjusted) and 95% confidence intervals (CIs) were estimated using Poisson regression with robust error variance. All analyses were stratified by race (Asian, black, brown/mixed, Brazilian indigenous, and white). Results: Approximately 84% of the pregnant women used at least one medication, with a lower proportion among white women. The most reported medications were antianemic preparations (71.08%; 95% CI 68.27-73.72%), analgesics (21.74%; 95% CI 19.36-24.32%), and drugs for functional gastrointestinal disorders (18.81%; 95% CI 16.57-21.28%). Approximately 29% of women took potentially risky medications during pregnancy, with a higher prevalence among Asian and white women. Factors associated with medication use during pregnancy include a greater number of prenatal consultations, higher education levels, health problems, and smoking. In addition, maternal age above 25 years, smoking status, and two or more previous pregnancies were associated with potentially risky medication use during pregnancy. Conclusion: A high prevalence of medication use during pregnancy was found; however, this prevalence was lower among white women. Nonetheless, black and brown women used antianemic preparations less frequently. This finding suggests that race is a factor of inequity in prenatal care, demanding public policies to mitigate it.

Ethno-racial inequalities on adverse birth and neonatal outcomes: a nationwide, retrospective cohort study of 21 million Brazilian newborns.

Background: Ethno-racial inequalities are critical determinants of health outcomes. We quantified ethnic-racial inequalities on adverse birth outcomes and early neonatal mortality in Brazil. Methods: We conducted a cohort study in Brazil using administrative linked data between 2012 and 2019. Estimated the attributable fractions for the entire population (PAF) and specific groups (AF), as the proportion of each adverse outcome that would have been avoided if all women had the same baseline conditions as White women, both unadjusted and adjusted for socioeconomics and maternal risk factors. AF was also calculated by comparing women from each maternal race/skin colour group in different groups of mothers' schooling, with White women with 8 or more years of education as the reference group and by year. Findings: 21,261,936 newborns were studied. If all women experienced the same rate as White women, 1.7% of preterm births, 7.2% of low birth weight (LBW), 10.8% of small for gestational age (SGA) and 11.8% of early neonatal deaths would have been prevented. Percentages preventable were higher among Indigenous (22.2% of preterm births, 17.9% of LBW, 20.5% of SGA and 19.6% of early neonatal deaths) and Black women (6% of preterm births, 21.4% of LBW, 22.8% of SGA births and 20.1% of early neonatal deaths). AF was higher in groups with fewer years of education among Indigenous, Black and Parda for all outcomes. AF increased over time, especially among Indigenous populations. Interpretation: A considerable portion of adverse birth outcomes and neonatal deaths could be avoided if ethnic-racial inequalities were non-existent in Brazil. Acting on the causes of these inequalities must be central in maternal and child health policies. Funding: Bill & Melinda Gates Foundation and Wellcome Trust.

Anti-Black racism and maternal death from COVID-19: what have we seen in the Pandemic? / Racismo antinegro e morte materna por COVID-19: o que vimos na Pandemia?

Anti-Black Racism traverses the lives of Black and Brown women, compromising sexual and reproductive health. Obstetric racism during pregnancy, prenatal care, childbirth, abortion, and puerperium affects these women, exposing them to harmful and often lethal maternal outcomes. This study aims to present racism and its manifestations in maternal death by COVID-19. It included data from COVID-19 notifications among pregnant women and puerperae recorded in the severe acute respiratory syndrome database (2021 and 2022). Information on race/skin color, age, region, clinical signs and symptoms, ICU, and deaths were collected. The results indicate how racism affects Black and Brown pregnant women and puerperae, who have higher lethality due to COVID-19 compared to White women (a difference of 14.02%), particularly in the puerperium. Black and Brown pregnant women least accessed the ICU. After adjustments, maternal death in the puerperium for Black women was 62% more likely than for White women (OR=1.62; 95%CI: 1.01-2.63). Racism and its manifestations (dis)organize the reproductive trajectories of Black and Brown women, whose interaction with sexism contributes to harmful and lethal maternal outcomes by COVID-19.

O racismo antinegro atravessa a vida das mulheres pretas e pardas comprometendo a saúde sexual e reprodutiva. O racismo obstétrico que ocorre durante a gravidez, pré-natal, parto, aborto e puerpério atinge estas mulheres expondo-as à desfechos maternos negativos e muitas vezes letais. Este estudo objetiva apresentar o racismo e suas manifestações na morte materna por COVID-19. Estudo transversal, com dados das notificações de COVID-19 entre gestantes e puérperas registradas na base de dados da Síndrome Respiratória Aguda Grave (2021 e 2022). Foram coletadas informações sobre raça/cor, idade, região, sinais e sintomas clínicos, UTI e óbitos. Os resultados apontam como o racismo afeta as gestantes e puérperas pretas e pardas, que apresentam maior letalidade por COVID-19 comparada às brancas (diferença que alcança os 14,02%), em particular no puerpério. Gestantes pretas e pardas são as que menos acessaram UTI. Após ajustes, a chance de óbito materno no puerpério para as mulheres pretas foi 62% maior em comparação as brancas (RC=1,62; 95%IC: 1,01-2,63). O racismo e suas manifestações (des)organizam as trajetórias reprodutivas das mulheres pretas e pardas que na sua interação com o sexismo contribuem para desfechos maternos negativos e letais por COVID-19.

Racial-Based Bullying and Substance Use: a Brazilian National Cross-Sectional Survey Among Students.

Racial discrimination has been associated with worse health status and risky health behavior. Understanding the relationship between racial-based bullying (RBB) - an overlap of bullying and interpersonal racial discrimination - and substance use can guide school-based actions to prevent bullying and substance use, but investigations rarely involve Brazilian students. We used data from the National Survey of School Health (PeNSE) 2015, which included 102,072 ninth-grade students from the capital and inland cities in the five regions of Brazil. Students self-reported their race/skin color according to the Brazilian official census. We explored racial and recent RBB differences in recent use of alcohol, tobacco, and other substances [marijuana, cocaine, crack, sniffed glue, loló/lança-perfume (ether and chloroform blend)] by comparing prevalence ratios (estimated with quasi-Poisson, crude, and adjusted models by demographic and socioeconomic characteristics) obtained from analyses of imputed data and complete case. We found that RBB prevalence increased according to racial categories associated with darker skin tones; racial differences in the prevalence of RBB were greater among girls than boys. Girls from all racial groups consistently had a higher prevalence of alcohol use than boys. RBB partially explained the recent use of alcohol and tobacco for the minority racial groups and was not associated with the use of other substances. School-based actions should explicitly incorporate anti-racist goals as strategies for substance use prevention, giving particular attention to gender issues in racial discrimination and alcohol use.

The combined effect of social pensions and cash transfers on child mortality: evaluating the last two decades in Brazil and projecting their mitigating effect during the global economic crisis.

Background: The world is currently experiencing multiple economic crises due to the COVID-19 pandemic, war in Ukraine, and inflation surge, which disproportionately affect children, especially in low- and middle-income countries (LMICs). We evaluated if the expansion of Social Assistance, represented by Social Pensions (SP) and Conditional Cash Transfers (CCT), could reduce infant and child mortality, and mitigate excess deaths among children in Brazil, one of the LMICs most affected by these economic crises. Methods: We conducted a retrospective impact evaluation in a cohort of Brazilian municipalities from 2004 to 2019 using multivariable fixed-effects negative binomial models, adjusted for relevant demographic, social, and economic factors, to estimate the effects of the SP and CCT on infant and child mortality. To verify the robustness of the results, we conducted several sensitivity and triangulation analyses, including difference-in-difference with propensity-score matching. These results were incorporated into dynamic microsimulation models to generate projections to 2030 of various economic crises and Social Assistance scenarios. Findings: Consolidated coverage of SP was associated with significant reductions in infant and child mortality rates, with a rate ratio (RR) of 0.843 (95% CI: 0.826-0.861) and 0.840 (95% CI: 0.824-0.856), respectively. Similarly, CCT consolidated coverages showed RRs of 0.868 (95% CI: 0.842-0.849) and 0.874 (95% CI: 0.850-0.899) for infant and child mortality, respectively. The higher the degree of poverty in the municipalities, the stronger the impact of CCT on reducing child mortality. Given the current economic crisis, a mitigation strategy that will increase the coverage of SP and CCT could avert 148,736 (95% CI: 127,148-170,706) child deaths up to 2030, compared with fiscal austerity measures. Interpretation: SP and CCT programs could strongly reduce child mortality in LMICs, and their expansion should be considered as an effective strategy to mitigate the impact of the current multiple global economic crises.

Association of Conditional Cash Transfers With Maternal Mortality Using the 100 Million Brazilian Cohort.

Importance: Conditional cash transfers (CCTs) have been consistently associated with improvements to the determinants of maternal health, but there have been insufficient investigations regarding their effects on maternal mortality. Objective: To evaluate the association between being a Bolsa Família program (BFP) beneficiary and maternal mortality and to examine how this association differs by duration of BFP receipt, maternal race, living in rural or urban areas, the Municipal Human Development Index (MHDI), and municipal primary health care coverage. Design, Setting, and Participants: This cross-sectional analysis was nested within the 100 Million Brazilian Cohort. Girls and women aged 10 to 49 years (hereinafter referred to as women) who had at least 1 live birth were included, using data from Brazilian national health databases linked to the 100 Million Brazilian Cohort (January 1, 2004, to December 31, 2015). Propensity score kernel weighting was applied to control for sociodemographic and economic confounders in the association between BFP receipt and maternal mortality, overall and stratified by different subgroups (race, urban or rural area, and MHDI), and duration of BFP receipt. Data were analyzed from July 12, 2019, to December 31, 2022. Main Outcome(s) and Measures: Maternal death. Results: A total of 6 677 273 women aged 10 to 49 years were included in the analysis, 4056 of whom had died from pregnancy-related causes. The risk of maternal death was 18% lower in women who received BFP (weighted odds ratio [OR], 0.82 [95% CI, 0.71-0.93]). A longer duration receiving BFP was associated with an increased reduction in maternal mortality (OR for 1-4 years, 0.85 [95% CI, 0.75-0.97]; OR for 5-8 years, 0.70 [95% CI, 0.60-0.82]; OR for ≥9 years, 0.69 [95% CI, 0.53-0.88]). Receiving BFP was also associated with substantial increases in the number of prenatal appointments and interbirth intervals. The reduction was more pronounced in the most vulnerable groups. Conclusions and Relevance: This cross-sectional analysis nested within the 100 Million Brazilian Cohort found an association between BFP receipt and maternal mortality. This association was of greater magnitude in women with longer exposure to BFP and in the most vulnerable groups. These findings reinforce evidence that programs such as BFP, which have already proven effective in poverty reduction, have great potential to improve maternal survival.

Intersection of Race and Gender in Self-Reports of Violent Experiences and Polyvictimization by Young Girls in Brazil.

OBJECTIVE: To explore racial disparities in self-reports of violent victimization and polyvictimization among young girls in Brazil and to analyze the distribution of prevalence rates across race groups and the estimated odds of exposure. DESIGN: Data from girls ages 15 and above (N=14,809) from the 2015 edition of PeNSE (National Adolescent School-based Health Survey) were analyzed. Survey weighted proportions and bivariate and multivariate logistic regressions were used to address the objectives. RESULTS: Independent of the girls' age, socioeconomic status, and region of residence, black, indigenous, mixed, and Asian descendant girls (relative to Whites) were more likely to report past experiences of being bullied, suffering physical violence, forced sexual intercourse, and polyvictimization (reporting all three events). Blacks had the highest rates of reporting being bullied and polyvictimization. Asian descendants had the highest reports of physical violence. Indigenous girls had the highest reports of forced sexual intercourse. CONCLUSIONS: This study documented disproportionate risks of violent victimization for young women of color among Brazilian students. The risks were significantly greater for those of darker skin tones and from ethnic minorities. IMPLICATIONS: These findings can inform the development of programs to protect young women from violence in Brazil and highlight the importance of including anti-racism strategies in such programs.

Ethnoracial inequalities and child mortality in Brazil: a nationwide longitudinal study of 19 million newborn babies.

BACKGROUND: Racism is a social determinant of health inequities. In Brazil, racial injustices lead to poor outcomes in maternal and child health for Black and Indigenous populations, including greater risks of pregnancy-related complications; decreased access to antenatal, delivery, and postnatal care; and higher childhood mortality rates. In this study, we aimed to estimate inequalities in childhood mortality rates by maternal race and skin colour in a cohort of more than 19 million newborns in Brazil. METHODS: We did a nationwide population-based, retrospective cohort study using linked data on all births and deaths in Brazil between Jan 1, 2012, and Dec 31, 2018. The data consisted of livebirths followed up to age 5 years, death, or Dec 31, 2018. Data for livebirths were extracted from the National Information System for livebirths, SINASC, and for deaths from the Mortality Information System, SIM. The final sample consisted of complete data for all cases regarding maternal race and skin colour, and no inconsistencies were present between date of birth and death after linkage. We fitted Cox proportional hazard regression models to calculate the crude and adjusted hazard ratios (HRs) and 95% CIs for the association between maternal race and skin colour and all-cause and cause-specific younger than age 5 mortality rates, by age subgroups. We calculated the trend of HRs (and 95% CI) by time of observation (calendar year) to indicate trends in inequalities. FINDINGS: From the 20 526 714 livebirths registered in SINASC between Jan 1, 2012, and Dec 31, 2018, 238 436 were linked to death records identified from SIM. After linkage, 1 010 871 records were excluded due to missing data on maternal race or skin colour or inconsistent date of death. 19 515 843 livebirths were classified by mother's race, of which 224 213 died. Compared with children of White mothers, mortality risk for children younger than age 5 years was higher among children of Indigenous (HR 1·98 [95% CI 1·92-2·06]), Black (HR 1·39 [1·36-1·41]), and Brown or Mixed race (HR 1·19 [1·18-1·20]) mothers. The highest hazard ratios were observed during the post-neonatal period (Indigenous, HR 2·78 [95% CI 2·64-2·95], Black, HR 1·54 [1·48-1·59]), and Brown or Mixed race, HR 1·25 [1·23-1·27]) and between the ages of 1 year and 4 years (Indigenous, HR 3·82 [95% CI 3·52-4·15]), Black, HR 1·51 [1·42-1·60], and Brown or Mixed race, HR 1·30 [1·26-1·35]). Children of Indigenous (HR 16·39 [95% CI 12·88-20·85]), Black (HR 2·34 [1·78-3·06]), and Brown or Mixed race mothers (HR 2·05 [1·71-2·45]) had a higher risk of death from malnutrition than did children of White mothers. Similar patterns were observed for death from diarrhoea (Indigenous, HR 14·28 [95% CI 12·25-16·65]; Black, HR 1·72 [1·44-2·05]; and Brown or Mixed race mothers, HR 1·78 [1·61-1·98]) and influenza and pneumonia (Indigenous, HR 6·49 [95% CI 5·78-7·27]; Black, HR 1·78 [1·62-1·96]; and Brown or Mixed race mothers, HR 1·60 [1·51-1·69]). INTERPRETATION: Substantial ethnoracial inequalities were observed in child mortality in Brazil, especially among the Indigenous and Black populations. These findings demonstrate the importance of regular racial inequality assessments and monitoring. We suggest implementing policies to promote ethnoracial equity to reduce the impact of racism on child health.

Mortality inequalities measured by socioeconomic indicators in Brazil: a scoping review.

OBJECTIVE: Summarize the literature on the relationship between composite socioeconomic indicators and mortality in different geographical areas of Brazil. METHODS: This scoping review included articles published between January 1, 2000, and August 31, 2020, retrieved by means of a bibliographic search carried out in the Medline, Scopus, Web of Science, and Lilacs databases. Studies reporting on the association between composite socioeconomic indicators and all-cause, or specific cause of death in any age group in different geographical areas were selected. The review summarized the measures constructed, their associations with the outcomes, and potential study limitations. RESULTS: Of the 77 full texts that met the inclusion criteria, the study reviewed 24. The area level of composite socioeconomic indicators analyzed comprised municipalities (n = 6), districts (n = 5), census tracts (n = 4), state (n = 2), country (n = 2), and other areas (n = 5). Six studies used composite socioeconomic indicators such as the Human Development Index, Gross Domestic Product, and the Gini Index; the remaining 18 papers created their own socioeconomic measures based on sociodemographic and health indicators. Socioeconomic status was inversely associated with higher rates of all-cause mortality, external cause mortality, suicide, homicide, fetal and infant mortality, respiratory and circulatory diseases, stroke, infectious and parasitic diseases, malnutrition, gastroenteritis, and oropharyngeal cancer. Higher mortality rates due to colorectal cancer, leukemia, a general group of neoplasms, traffic accident, and suicide, in turn, were observed in less deprived areas and/or those with more significant socioeconomic development. Underreporting of death and differences in mortality coverage in Brazilian areas were cited as the main limitation. CONCLUSIONS: Studies analyzed mortality inequalities in different geographical areas by means of composite socioeconomic indicators, showing that the association directions vary according to the mortality outcome. But studies on all-cause mortality and at the census tract level remain scarce. The results may guide the development of new composite socioeconomic indicators for use in mortality inequality analysis.

Effects of sexual orientation-based bullying on feelings of loneliness and sleeping difficulty among Brazilian middle school students.

OBJECTIVE: To investigate the extent to which sexual orientation-based bullying relates to self-reported feelings of loneliness and sleeping difficulty among Brazilian middle school students. METHOD: This is a cross-sectional study using data from the 2015 PeNSE (Pesquisa Nacional de Saúde do Escolar), a survey designed to monitor the health of children and adolescents enrolled in the ninth grade in public and private Brazilian schools. Multiple linear regressions stratified by sex were used on a sample of 101,646 students, considering as reference students who had not experienced bullying, as well as students who had experienced other causes of bullying; a significance level of p<0.05 was accepted. RESULTS: When the reference group was composed of students who had not experienced bullying, the associations between sexual orientation-based bullying and feelings of loneliness and between sexual orientation-based bullying and sleeping difficulty were positive (p<0.05) for both male and female students, with magnitudes about twice as large as those found among those who reported having experienced other cause s of bullying. However, when the reference group was composed of students who had experienced other causes of bullying, only the association between sexual orientation-based bullying and feelings of loneliness was positive (p<0.05) for both male and female students. CONCLUSION: This study highlights that sexual orientation-based bullying is a predictor of feelings of loneliness.

Effect of the zero-tolerance drinking and driving law on mortality due to road traffic accidents according to the type of victim, sex, and age in Rio de Janeiro, Brazil: An interrupted time series study.

Objective: The objective of this study was to estimate the effect of the Brazilian zero-tolerance drinking and driving law on mortality rates due to road traffic accidents according to the type of victim, sex, and age. Methods: An interrupted time series design was used to compare yearly mortality rates due to road traffic accidents in Rio de Janeiro, Brazil, before and after the zero-tolerance drinking and driving law came into effect on June 19, 2008. Yearly mortality rates were compared according to the type of victim: pedestrian, cyclist, motorcyclist, and vehicle occupant. We used the Prais-Winsten procedure of autoregression in the analysis of time series; the outcome of this analysis was the annual percentage change in the rates. Overall and stratified analyses were conducted to investigate whether the zero-tolerance drinking and driving law may have had a distributional effect on mortality rates due to road traffic accidents depending on sex and age group; a significance level of P < .01 was accepted. Results: From 1999 to 2016, there were 15,629 deaths due to road traffic accidents in Rio de Janeiro. The effect of the zero-tolerance drinking and driving law on overall mortality rates due to road traffic accidents in Rio de Janeiro was not statistically significant. However, among cyclists and motorcyclists aged ≥60 years and among pedestrians of both sexes and aged ≥20 years, the effect of the zero-tolerance drinking and driving law was to decrease mortality due to road traffic accidents at a yearly rate. Conclusion: There is evidence of reduced mortality rates due to road traffic accidents among cyclists and motorcyclists aged ≥60 years and among pedestrians of both sexes aged ≥20 years in the second major Brazilian capital 9 years after the zero-tolerance drinking and driving law was adopted.

Propensity Score Methods in Health Technology Assessment: Principles, Extended Applications, and Recent Advances.

Randomized clinical trials (RCT) are accepted as the gold-standard approaches to measure effects of intervention or treatment on outcomes. They are also the designs of choice for health technology assessment (HTA). Randomization ensures comparability, in both measured and unmeasured pretreatment characteristics, of individuals assigned to treatment and control or comparator. However, even adequately powered RCTs are not always feasible for several reasons such as cost, time, practical and ethical constraints, and limited generalizability. RCTs rely on data collected on selected, homogeneous population under highly controlled conditions; hence, they provide evidence on efficacy of interventions rather than on effectiveness. Alternatively, observational studies can provide evidence on the relative effectiveness or safety of a health technology compared to one or more alternatives when provided under the setting of routine health care practice. In observational studies, however, treatment assignment is a non-random process based on an individual's baseline characteristics; hence, treatment groups may not be comparable in their pretreatment characteristics. As a result, direct comparison of outcomes between treatment groups might lead to biased estimate of the treatment effect. Propensity score approaches have been used to achieve balance or comparability of treatment groups in terms of their measured pretreatment covariates thereby controlling for confounding bias in estimating treatment effects. Despite the popularity of propensity scores methods and recent important methodological advances, misunderstandings on their applications and limitations are all too common. In this article, we present a review of the propensity scores methods, extended applications, recent advances, and their strengths and limitations.

Administrative Data Linkage in Brazil: Potentials for Health Technology Assessment.

Health technology assessment (HTA) is the systematic evaluation of the properties and impacts of health technologies and interventions. In this article, we presented a discussion of HTA and its evolution in Brazil, as well as a description of secondary data sources available in Brazil with potential applications to generate evidence for HTA and policy decisions. Furthermore, we highlighted record linkage, ongoing record linkage initiatives in Brazil, and the main linkage tools developed and/or used in Brazilian data. Finally, we discussed the challenges and opportunities of using secondary data for research in the Brazilian context. In conclusion, we emphasized the availability of high quality data and an open, modern attitude toward the use of data for research and policy. This is supported by a rigorous but enabling legal framework that will allow the conduct of large-scale observational studies to evaluate clinical, economical, and social impacts of health technologies and social policies.

Racismo antinegro e morte materna por COVID-19: o que vimos na Pandemia? / Anti-Black racism and maternal death from COVID-19: what have we seen in the Pandemic?

Resumo O racismo antinegro atravessa a vida das mulheres pretas e pardas comprometendo a saúde sexual e reprodutiva. O racismo obstétrico que ocorre durante a gravidez, pré-natal, parto, aborto e puerpério atinge estas mulheres expondo-as à desfechos maternos negativos e muitas vezes letais. Este estudo objetiva apresentar o racismo e suas manifestações na morte materna por COVID-19. Estudo transversal, com dados das notificações de COVID-19 entre gestantes e puérperas registradas na base de dados da Síndrome Respiratória Aguda Grave (2021 e 2022). Foram coletadas informações sobre raça/cor, idade, região, sinais e sintomas clínicos, UTI e óbitos. Os resultados apontam como o racismo afeta as gestantes e puérperas pretas e pardas, que apresentam maior letalidade por COVID-19 comparada às brancas (diferença que alcança os 14,02%), em particular no puerpério. Gestantes pretas e pardas são as que menos acessaram UTI. Após ajustes, a chance de óbito materno no puerpério para as mulheres pretas foi 62% maior em comparação as brancas (RC=1,62; 95%IC: 1,01-2,63). O racismo e suas manifestações (des)organizam as trajetórias reprodutivas das mulheres pretas e pardas que na sua interação com o sexismo contribuem para desfechos maternos negativos e letais por COVID-19.

Abstract Anti-Black Racism traverses the lives of Black and Brown women, compromising sexual and reproductive health. Obstetric racism during pregnancy, prenatal care, childbirth, abortion, and puerperium affects these women, exposing them to harmful and often lethal maternal outcomes. This study aims to present racism and its manifestations in maternal death by COVID-19. It included data from COVID-19 notifications among pregnant women and puerperae recorded in the severe acute respiratory syndrome database (2021 and 2022). Information on race/skin color, age, region, clinical signs and symptoms, ICU, and deaths were collected. The results indicate how racism affects Black and Brown pregnant women and puerperae, who have higher lethality due to COVID-19 compared to White women (a difference of 14.02%), particularly in the puerperium. Black and Brown pregnant women least accessed the ICU. After adjustments, maternal death in the puerperium for Black women was 62% more likely than for White women (OR=1.62; 95%CI: 1.01-2.63). Racism and its manifestations (dis)organize the reproductive trajectories of Black and Brown women, whose interaction with sexism contributes to harmful and lethal maternal outcomes by COVID-19.

Asthma trend in adolescence in Brazil: results of the National Adolescent School-based Health Survey (PeNSE 2012-2015). / Tendência da asma na adolescência no Brasil: resultados da Pesquisa Nacional de Saúde do Escolar (PeNSE) 2012 e 2015.

OBJECTIVE: To compare the evolution of asthma indicators in the editions of the National School Health Survey (PeNSE 2012 and 2015). METHODS: Cross-sectional study including Brazilian 9th grade students from public and private schools. Wheezing was assessed through the question: "In the past 12 months, did you have wheezing (or chirping) chest? (yes/no)", and to assess lifetime presence of asthma, the question was "Have you ever had asthma? (yes/no)". RESULTS: Of the students, 23,52% reported wheezing or chirping chest in the past 12 months, with prevalences ranging from 16,80% (in Salvador, Bahia) to 27,43% (in Porto Alegre, Rio Grande do Sul). Lifetime presence of asthma was reported by 17,92% of the students, ranging from 13,98% (in Campo Grande, Mato Grosso do Sul) to 30,35% (in Porto Alegre, Rio Grande do Sul). There was also a decrease in the prevalence of self-report of wheezing/chirping chest in the last 12 months between the two editions of the survey (2012/2015) in 20 of the 27 Brazilian state capitals, especially in Belo Horizonte, Florianópolis, Cuiabá and Goiânia. However, prevalence of lifetime diagnostic of asthma increased from 2012 to 2015 in 26 of the 27 Brazilian state capitals. CONCLUSION: There was a decrease in the prevalence of self-report of asthma symptoms and an increase of self-reported lifetime presence of asthma. Certainly, monitoring indicators of asthma prevalence is of high importance for health knowledge and the development of public policies.

OBJETIVO: Comparar a evolução dos indicadores referentes à asma nas edições da Pesquisa Nacional de Saúde do Escolar (PeNSE) 2012 e 2015. MÉTODOS: Estudo transversal em que foram incluídos escolares do nono ano de escolas públicas e privadas das capitais brasileiras. Para saber se o escolar teve chiado no peito nos 12 meses anteriores ao inquérito, foi feita a pergunta: "Nos últimos 12 meses, você teve chiado (ou piado) no peito?" (sim/não). E para saber se teve asma alguma vez na vida foi questionado: "Você teve asma alguma vez na vida?" (sim/não). RESULTADOS: Verificou-se que 23,52% dos estudantes relataram chiado ou piado no peito nos ultimos 12 meses, variando de 16,80% em Salvador (Bahia) a 27,43% em Porto Alegre (Rio Grande do Sul). Ter asma alguma vez na vida foi relatado por 17,92% dos estudantes, variando de 13,98% em Campo Grande (Mato Grosso do Sul) a 30,35% em Porto Alegre (Rio Grande do Sul). Também foi verificada redução da prevalência de chiado (ou piado) no peito nos últimos 12 meses, entre as duas pesquisas (PeNSE 2012 e 2015) em 20 das 27 capitais do Brasil, com destaque para Belo Horizonte, Florianópolis, Cuiabá e Goiânia. Por outro lado, houve aumento da prevalência daqueles que relataram asma alguma vez na vida em 26 das 27 capitais do país. CONCLUSÃO: Houve tendência à redução dos sintomas de asma nos últimos 12 meses, enquanto se observa aumento na proporção de adolescentes em que a asma foi referida alguma vez na vida. De certo que o monitoramento da asma ao longo dos anos é imprescindível para gerar conhecimentos e embasar políticas públicas de controle da asma.

Area deprivation measures used in Brazil: a scoping review.

OBJECTIVE: To describe and assess currently used area-based measures of deprivation in Brazil for health research, to the purpose of informing the development of a future small area deprivation index. METHODS: We searched five electronic databases and seven websites of Brazilian research institutions and governmental agencies. Inclusion criteria were: studies proposing measures of deprivation for small areas (i.e., finer geography than country-level) in Brazil, published in English, Portuguese or Spanish. After data-extraction, results were tabulated according to the area level the deprivation measure was created for and to the dimensions of deprivation or poverty included in the measures. A narrative synthesis approach was used to summarize the measures available, highlighting their utility for public health research. RESULTS: A total of 7,199 records were retrieved, 126 full-text articles were assessed after inclusion criteria and a final list of 30 articles was selected. No small-area deprivation measures that have been applied to the whole of Brazil were found. Existing measures were mainly used to study infectious and parasitic diseases. Few studies used the measures to assess inequalities in mortality and no studies used the deprivation measure to evaluate the impact of social programs. CONCLUSIONS: No up-to-date small area-based deprivation measure in Brazil covers the whole country. There is a need to develop such an index for Brazil to measure and monitor inequalities in health and mortality, particularly to assess progress in Brazil against the Sustainable Development Goal targets for different health outcomes, showing progress by socioeconomic groups.
