Depression is associated with unintended pregnancy among fathers during the first 3 years after childbirth

BackgroundThe aim of the present study is to estimate the prevalence of unintended pregnancy in fathers with children aged less than or equal to 36 months and evaluate whether unintended pregnancy is associated with depression after controlling for covariates. MethodsWe used data from the Brazilian National Health Survey (PNS) of 2019, a cross-sectional study that comprised a representative sample of residents in private households in Brazil. For the analysis of this study, we selected 30,579 men (> 14 years old) who answered to the Selected Resident questionnaire of the PNS and reported having a biological child (son). Among these 4806 had a child with less than 4 years of age and were used in our analysis. ResultsThe prevalence of unintended pregnancy in this group of fathers with a child ≤ 3 years was 35.0 % (95 % CI 32.6–37.5). In the final adjusted model, the variables associated with depression were: PHQ-9 total score (OR: 1.07, 95 % CI 1.03–1.11, p ≤0.001), a higher father's age (OR 1.01, 95 % CI 1.01–1.02), a higher father's age at birth (OR: 0.92, 95 % CI 0.90–0.94), self-reported black (OR: 3.00, 95 % CI 1.94–4.66), brown (OR: 1.63, 95 % CI 1.25–2.13) or indigenous (OR: 0.22, 95 % CI 0.07–0.69) skin color, lower per capita family income >1 to 2 MW (OR: 1.54, 95 % CI 1.01–2.35), ½ to 1 MW (OR: 2.22, 95 % CI 1.46–3.38) and up to 1 MW (OR: 1.76, 95 % CI 1.19–2.59) and not participating in the partner's prenatal appointments (OR: 2.04, 95 % CI 1.55–2.68). DiscussionIn our study, the prevalence of unplanned pregnancy among fathers of child less than 4 years of age is high, and it is associated with depression. Black and brown self-reported skin color, lower family income and higher father's age are associated with increased risk of unintended pregnancy.

INTERNAÇÃO POR FRATURA DE FÊMUR NO BRASIL NO PERÍODO DE 2012 A 2022: ANÁLISE DE ACORDO COM A COR DA PELE

OBJECTIVE: To retrospectively analyze the total number of hospitalizations for femoral fractures in the elderly according to regions in Brazil and skin color, from 2012 to 2022. METHODS: Ecological and retrospective time series study that evaluated data on femoral fractures in the elderly, based on data available on the Ministry of Health websites. The following variables were evaluated: Total hospitalizations according to skin color, age group and type of service used. RESULTS: The number of white people was much higher in the private health service. Regarding brown skin color, the north and southeast had more people hospitalized in the public sector. Regarding hospitalization according to age group, all categories had the same behavior, with an increase in the number of hospitalizations as there is an increase in age magnitude. There was an increase in the number of hospitalizations over the years, only between 2019 and 2020, there was a slight decrease, observed especially in people with brown skin. CONCLUSION: There is a discrepancy in the number of hospitalizations for femur fractures in the elderly between Brazilian regions. This study shows that femoral fractures continue to be a health problem present in the Brazilian population, regardless of skin color and that their increasing behavior over the years reflects the aging of the population.

Risks, demands, and health damages faced by nursing workers in confronting Covid-19

This article aims to analyze how nursing work processes have impacted the health of workers, taking into consideration the risks, demands, and potential damages. Nursing work is characterised by a demand for care that affects workers on various levels: physical, emotional, and psychological during the pandemic, there has been an exacerbation of labor precarity, increased exposure to risks and demands stemming from their work processes, and consequently, health damage. A mixed-method approach was employed, using the triangulation strategy of three data collection techniques: questionnaire surveys, focus groups, and individual interviews. It was found that the majority of participants are women, aged between 30 and 39, identify as having a brown skin color, work as nursing technicians, and have been employed in hospitals specialising in severe Covid-19 cases. The thematic categories identified were workload overload; lack of breaks or facilities for physiological needs; absence, improvisation, or inadequacy of Personal Protective Equipment (PPE); noise; health damage: fatigue and illness. These categories have corresponding variables that, in turn, were statistically associated with health damage, such as muscular disorders, sleep disturbances, mental health issues, and dermatological problems.

A practical classification scale for the dermatology management of individuals with skin of color: the colorimetric scale for skin of color.

A simple and rapid method that is not based on race and ethnicity for classifying people with skin of color is of paramount importance in dermatology. The currently used Fitzpatrick classification of sun-reactive skin types is inadequate. Newer scales that have been used in immigration surveys and sociology studies are not applicable in the office setting. A new, non-racial and non-ethnic, colorimetric scale for skin of color has recently been proposed that is simple to perform. The scale has five colors: very light beige (skin color type 1), light brown (skin color type 2), medium brown (skin color type 3), dark brown (skin color type 4) and very dark brown (skin color type 5); an individual with white skin, such as in albinism, would have a skin color type 0 in this classification. In conclusion, the colorimetric scale enables the rapid classification of individuals with skin of color and allows for accurate assessment of skin cancer risk, more appropriate management of cosmetic dermatologic procedures and aesthetic devices, and enhanced ability for focused counseling regarding hair products, skin care interventions, and color-targeted makeup based on the person's skin tone.

Racial disparities in breast cancer survival after treatment initiation in Brazil: a nationwide cohort study

Breast cancer is a public health priority in Brazil and ensuring equity in health care is one of the cancer control plan goals. Our aim was to present the first assessment on the influence of race or skin colour on breast cancer survival at the national level. In this nationwide cohort study, data on women who initiated treatment for breast cancer in the public health-care system (Sistema Unico de Saúde), Brazil, were assembled through record linkage of administrative and mortality information systems. The administrative information systems were the Outpatient Information System (data from high complexity procedure authorisations) and the Hospital Information System (data from hospitalisation authorisations). We included women aged 19 years or older who started treatment between Jan 1, 2008, and Nov 30, 2010; self-identified as having White, Black, or Brown race or skin colour; had tumour stage I-IV; and were treated with chemotherapy or radiotherapy, or both. Patients were followed up until Dec 31, 2015. Patients with only hormone therapy records or who underwent only surgery were excluded. The Kaplan-Meier method was used to estimate crude overall survival for race or skin colour by time since treatment initiation, and Cox regression to estimate all-cause mortality hazard ratios (HRs) before and after adjustment for other covariates. We identified 59 811 women treated for stage I-IV breast cancer. 37 318 (62·4%) women identified themselves as White, 18 779 (31·4%) as Brown, and 3714 (6·2%) as Black. 5-year overall survival probability was higher for White women (74% [95% CI 73-74]) than Black women (64% [62-65]; p<0·0001). In adjusted regression models stratified by the absence of hormone therapy, Black women had a 24% (HR 1·24 [95% CI 1·16-1·34]; p<0·0001) higher risk of all-cause death than White women, and in the presence of hormone therapy Black women had a 25% (1·25 [1·14-1·38]; p<0·0001) higher risk of all-cause death than White women. Black skin colour was identified as a statistically significant risk marker for lower 5-year survival probability and higher risk of all-cause death among women treated for breast cancer by the Sistema Unico de Saúde. Actions to understand and mitigate this unfair difference in health results are urgently needed.

Characterization of teaching-learning tutors in public health services and topics of interest for their work.

To describe the profile of teaching-learning tutors in public health services and investigate which topics are of greatest interest in development spaces for these actors. Cross-sectional study. Eligible tutors of Health Care Planning. Data collection using an electronic questionnaire composed of closed questions on sociodemographic characteristics, training and performance. Chi-square test used to compare proportions according to tutor typologies. A total of 614 tutors worked in Brazil's five geographic regions, the majority in primary care (82%), followed by state/regional work (13%) and specialized outpatient care (5%). The majority reported being female, of brown skin color, from the nursing field, having worked as a tutor for less than a year, and with no previous experience in preceptorship or similar. The most important topics were Health Care Networks, risk stratification for chronic conditions and the functions of specialized outpatient care. The predominance of certain characteristics among tutors was identified, with differences between the types of work. The findings can support managers in the process of selecting and developing tutors in Health Care Planning.

Integrative transcriptomics and metabolomics analysis of body color formation in the common carp

The coloration of aquatic animals influences their adaptability to environment and economic values. The skin color of common carp (Cyprinus carpio) is various between different strains. Hebao red carp is famous for its bright red color, which is different from the brown skin color of wild-type common carp. To reveal the different components and molecular mechanism between skins with red and brown colors, LC-MS and transcript analysis were conducted. 614 significantly different metabolites (SDM) and 392 differentially expressed genes (DEG) were detected between skins of Hebao red carp (HB) and Yellow River carp (YR). There are 35 KEGG pathways shared by DEGs and SDMs, among which microbial metabolism in diverse environments (ko01120), carbon metabolism (ko01200) and metabolic pathways (ko01100) were significantly enriched by DEGs and SDMs. Pathways related to melanin synthesis and retinal metabolism were down-regulated in HB, such as adh8a, adh8b, cyp3a, dhrs3b, mart1, hgd, hpd and maiA, which may induce the disappear of melanocytes and accumulation of carotenoid. The content of lutein in HB skin was significantly higher than in YR. This study shows retinol and carotenoid metabolism is vital in the common carp body color formation, and will help understand the mechanism of color determination in common carp.

Novel observations of "freeze resistance" and dynamic blue and green dorsal coloration in frozen and thawing Dryophytes chrysoscelis.

Freeze tolerant animals survive the winter by tolerating the freezing and thawing of up to 70% of body water and the respective cessation and resumption of essential functions including circulation and respiration during each freeze-thaw cycle. Cope's gray treefrog Dryophytes chrysoscelis is a freeze tolerant anuran that uses a system of cryoprotectants to prevent intracellular freezing and mitigate osmotic stress during freezing and thawing episodes. Morphological features were documented in D. chrysoscelis using a repeated freeze-thaw protocol. Dorsal skin in frozen frogs was distinctly blue and green before reverting to brown during thawing. The dorsal color change in frozen frogs does not function similarly to other known color change events in amphibians. The return to brown skin color in thawing animals coincides with recovery of vital functions in freeze tolerant frogs, suggesting that dorsal color change is an indicator of postfreeze recovery in D. chrysoscelis. We also provide evidence of "freeze resistance" in D. chrysoscelis. Two individuals did not freeze following three successive bouts of ice inoculation at -2.5°C and maintained brown dorsal color despite ice crystallization on the dorsum and contact with frozen substrate. Both frogs had similar plasma osmolality, circulating cryoprotectants, and incidence of cryoinjury compared to frogs that were frozen and thawed once or three times. Freeze resistance may be explained by physical changes in the skin including lipid accumulation and dehydration. This integrative study presents novel attributes of organismal freeze tolerance in D. chrysoscelis.

Economic and racial disparities of the weather impact on air quality in Brazil

Several studies have quantified the air pollution exposure disparities across racial and income groups. However, there is still a lack of investigations assessing disparities related to the impacts of weather on air pollution, which could indicate target air pollution reduction strategies under different climate scenarios. Our study aims to address this gap by estimating the economic and racial disparities of the weather impact on air quality in Brazil between 2003 and 2018. First, we used a generalized additive approach to estimate the weather-related changes in PM2.5. This framework derived “weather penalty”, which a positive penalty suggests that an increase in PM2.5 was associated with long-term weather changes in the study period. Then, we estimated the population-weighted weather penalty for racial and income groups. Average penalty for the White population (the most-exposed group) was 31% higher than that of the Pardo population (the least-exposed group, mainly people of light brown skin color) in Brazil. In the stratification analysis by region, the Midwest and South were the regions where the black population was the most-exposed group. For the income group, our results indicate that the high-income population group was the most-exposed group in all analyses, including the national and the regional analyses. These findings are somewhat surprising, as previous studies have shown that minority and low-income populations tend to be more exposed to air pollution, than white and higher-income populations. However, our study suggests that disparities in exposure to air pollution may be more complex and nuanced than previously thought. Further research is needed to better understand the underlying drivers of these environmental disparities, and to develop targeted interventions to reduce exposures.

Factors associated with inequalities in social conditions in the health of elderly white, brown and black people in the city of São Paulo, Brazil

The scope of this study is to identify determining factors of disparities in social conditions in the health of non-institutionalized elderly people in the city of São Paulo, from the standpoint of self-declaration of skin color. It is a cross-sectional study with a representative sample of 1,017 elderly participants in the "2015 Health Survey of the Municipality of São Paulo". The analysis used crude and adjusted Poisson regression models, reporting the prevalence ratio and 95% confidence intervals as a measure of association between the variables. In the adjusted analysis, brown and black skin color was positively associated with worse schooling, negative self-assessment of health status, health insurance and access to public health services. On the one hand, black skin color was no longer associated with the lowest income, however, it was associated with arterial hypertension. On the other hand, brown skin color was associated with low income, but not with arterial hypertension. Elderly black and brown people had worse health conditions, less access to private health services and socioeconomic resources. These results are compatible with the hypothesis of structural racism in São Paulo's society and may inform social health policies aimed at promoting health and social justice.

Severe acute respiratory syndrome by influenza and factors associated with death in older adults: a population study.

Influenza is characterized by an acute viral infection, which can lead to severe conditions and death, especially in vulnerable populations, such as older adults. Therefore, we sought to analyze cases of severe acute respiratory syndrome (SARS) due to influenza in older adults registered in Brazil and investigate the factors related to death due to this disease. This is a cross-sectional, population-based study that used secondary data from the Influenza Epidemiological Surveillance Information System (IESIS-Influenza). Older adults aged 60 years and above with laboratory diagnosis of influenza were included. A total of 3,547 older adults with SARS due to influenza were included, out of which 1,185 cases with death as the outcome were identified. Among older adults with death as the outcome, 87.4% were not vaccinated against influenza. The main risk factors for death were invasive ventilatory support use, intensive care unit admission, brown skin color and dyspnea (p < 0.001). This study described the profile of older adults with SARS due to influenza in Brazil. Factors associated with death in this population were identified. Moreover, the need to encourage compliance with vaccination among older adults is evident in order to prevent severe cases and unfavorable outcomes related to influenza.

Ethnic/Racial Disparity in Mortality from COVID-19: Data for the Year 2020 in Brazil.

The study aimed to investigate ethnic/racial disparities in COVID-19 mortality in Brazilian federative units and their respective capitals in 2020. Population data and number of COVID-19 deaths were extracted by skin color (white, black, brown and indigenous) from all Brazilian states and their respective capitals. The mortality rate of COVID-19 by ethnicity in Brazilian states was higher between people from brown skin color, followed by indigenous and black. Only in one state, in the Federal District and in the federal capital, age-standardized mortality rates were higher among white's people. There is a high percentage of deaths from COVID-19 higher than expected among non-white individuals, especially in south-central states and capitals of the country. Mortality from COVID-19 affect ethnic-racial groups unevenly in Brazil and the number of excess deaths among non-whites was over 9000. Urgent government measures are needed to reduce the racial disparity in health indicators in Brazil.

Comparative transcriptome analysis of skin color-associated genes in leopard coral grouper (Plectropomus leopardus)

BackgroundThe leopard coral grouper (Plectropomus leopardus) is an important economic species in East Asia-Pacific countries. To meet the market demand, leopard coral grouper is facing overfishing and their population is rapidly declining. With the improvement of the artificial propagation technique, the leopard coral grouper has been successfully cultured by Fisheries Research Institute in Taiwan. However, the skin color of farmed individuals is often lacking bright redness. As such, the market price of farmed individuals is lower than wild-type.ResultsTo understand the genetic mechanisms of skin coloration in leopard coral grouper, we compared leopard coral grouper with different skin colors through transcriptome analysis. Six cDNA libraries generated from wild-caught leopard coral grouper with different skin colors were characterized by using the Illumina platform. Reference-guided de novo transcriptome data of leopard coral grouper obtained 24,700 transcripts, and 1,089 differentially expressed genes (DEGs) were found between red and brown skin color individuals. The results showed that nine candidate DEGs (epha2, sema6d, acsl4, slc7a5, hipk1, nol6, timp2, slc25a42, and kdf1) significantly associated with skin color were detected by using comparative transcriptome analysis and quantitative real-time polymerase chain reaction (qRT-PCR).ConclusionsThe findings may provide genetic information for further skin color research, and to boost the market price of farmed leopard coral grouper by selective breeding.

Malaria and environmental, socioeconomics and public health conditions in the municipality of São Félix do Xingu, Pará, Eastern Amazon, Brazil: An ecological and cross-sectional study.

Malaria is a parasitosis conditioned by several factors. This study sought to analyze the spatial distribution of malaria considering environmental, socioeconomic, and political variables in São Félix do Xingu, Pará, Brazil, from 2014 to 2020. Epidemiological, cartographic, and environmental data were obtained from the Ministry of Health, Brazilian Geographical and Statistical Institute, and National Space Research Institute. Statistical and spatial distribution analyses were performed using chi-squared tests of expected equal proportions and the kernel and bivariate global Moran's techniques with Bioestat 5.0 and ArcGIS 10.5.1. The highest percentage of cases occurred in adult males with brown skin color, mainly placer miners, with a primary education level, living in rural areas, who were infected with Plasmodium vivax and with parasitemia of two or three crosses as diagnosed by the thick drop/smear test. The disease had a non-homogeneous distribution, with distinct annual parasite indices associated with administrative districts and clusters of cases in locations with deforestation, mining, and pastures close to Conservation Units and Indigenous Lands. Thus, a direct relationship between areas with cases and environmental degradation associated with land use was demonstrated, along with the precarious availability of health services. Pressure on protected areas and epidemiological silence in Indigenous Lands were also noted. Environmental and socioeconomic circuits were identified for development of diseases associated with precarious health services in the municipality. These findings highlight the need to intensify malaria surveillance and contribute to the systematic knowledge of malaria's epidemiology by considering the complexity of its conditioning factors.

Demand and use of health services by Brazilian adolescents, according to the National School Health Survey 2019.

To analyze the demand and use of health services by Brazilian adolescents, according to sociodemographic characteristics. Cross-sectional study with data from the 2019 National School Health Survey, that assessed 124,898 adolescents aged 13 to 17 years. The crude and adjusted prevalence ratios (RPaj) by sex, age, and school administrative status and their 95% confidence intervals (95%CI) were calculated for the variables "search for a service or health professional", "search for a Basic Health Unit" and "assistance at the Basic Health Unit", using Poisson regression with robust variance. The demand for a health service was reported by 56.56% (95%CI 55.82-57.29) of the adolescents and was lower among male students (RPaj: 0.95; 95%CI 0.94-0.95); those with black skin color (RPaj: 0.95; 95%CI 0.94-0.97), brown skin color (RPaj: 0.97; 95%CI 0.96-0.98), yellow skin color and indigenous ethnicity (RPaj: 0.95; 95%CI 0.94-0.97); public school students (RPaj: 0.90; 95%CI 0.89-0.90); and rural residents (RPaj: 0.96; 95%CI 0.94-0.98). A Basic Health Unit was the service sought by 74.08% (95%CI 73.21-74.94) of adolescents, more frequently among students of brown skin color (RPaj: 1.06; 95%CI 1.03-1.08), from public schools (RPaj: 1.32; 95%CI 1.29-1.35) and residing in rural areas (RPaj: 1.05; 95%CI 1,01-1,09). The main reason for seeking the Basic Health Unit was vaccination (27,93%; 95%CI 27,07-28,81). More than half of the adolescents searched for a health service, which means that this group has a high demand. However, health inequalities still persist and point to the importance of health care planning, reception conditions, and the quality of care provided.

Association between multimorbidity, intensive care unit admission, and death in patients with COVID-19 in Brazil: a cross-section study, 2020.

Multimorbidity can influence intensive care unit (ICU) admissions and deaths due to coronavirus disease (COVID-19). To analyze the association between multimorbidity, ICU admissions, and deaths due to COVID-19 in Brazil. This cross-sectional study was conducted using data from patients with severe acute respiratory syndrome (SARS) due to COVID-19 recorded in the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) in 2020. Descriptive and stratified analyses of multimorbidity were performed based on sociodemographic, ventilatory support, and diagnostic variables. Poisson regression was used to estimate the prevalence ratios. We identified 671,593 cases of SARS caused by COVID-19, of which 62.4% had at least one morbidity. Multimorbidity was associated with male sex, age 60-70 and ≥ 80 years, brown and black skin color, elementary education and high school, ventilatory support, and altered radiologic exams. Moreover, all regions of the country and altered computed tomography due to COVID-19 or other diseases were associated with death; only the northeast region and higher education were associated with ICU admission. Our results showed an association between multimorbidity, ICU admission, and death in COVID-19 patients in Brazil.

Diversity Assessment Among Seventy-Four Potato Genotypes for Selection in Breeding Program

Sustainable production of food crops relies on germplasm improvement and genetic diversity. In the present study, seventy-four potato genotypes were evaluated for diversity analysis during autumn 2017-2018 and 2018-2019 at NARC, Islamabad. Our results showed significant diversity in qualitative traits with reference to skin color of five types (Red, yellowish, brown, light yellow, light brown skin color tubers=5), three types of flesh color (Yellow, cream and white flesh color tubers=3), three sizes of tubers (Medium, small and large size tubers=3) and four shape of tuber (Oval, round, oblong, elliptic= 4 shapes) and four different eyes color (Brown, light brown, dark red and yellow eyes color=4). Potato genotype under study had very high genetic variance for quantitative attributes including weight of tuber per plant and weight number of tubers per lane, leaf area and plant height. Significant positive correlation was observed between number of tubers per plant (TPP) with number of eyes on tubers (r = 0.241) and number of tubers per lane (TPL) (r = 0.349). Plant height was found significantly positive correlated with leaf area (r= 0.456), germination percentage (r = 0.255) and weight of tubers per plant (r = 0.307). Leaf area (LA) showed positive significant correlation with number of tubers per plant (r = 0.466) and weight of tubers per plant (r = 0.263), yield and harvest index (r = 0.798, 0.755, 0.255). Weight of tubers per lane (WTL) showed positive correlation with weight of tubers per plant (r = 0.387). Regarding the interrelation between the traits and genotypes, the first two principal component axes (PC1, 24.83% and PC2, 23.46%) accounted for about 48.29% of the total variability reflecting the complexity of the variation between the plotted traits of genotypes. The present study will be useful for the precise selection for effective breeding program.

Factors associated with death due to severe acute respiratory syndrome caused by influenza: Brazilian population study

IntroductionInfluenza infection is characterized by acute viral infection of high transmissibility. Worsening of the case can lead to the need for hospitalization, severe acute respiratory syndrome (SARS) and even death. MethodThis is a cross-sectional population-based study that used secondary database from the Brazilian Influenza Epidemiological Surveillance Information System. Only cases of adults with diagnosis of influenza by RT-PCR and case evolution recorded were included. ResultsWe identified 2273 adults with SARS by influenza, 343 of which had death as an outcome. The main risk factors for death were lack of hospitalization, not having cough and age, both with p < 0.001. In addition, without asthma, having black skin color, not receiving flu vaccine, having brown skin color and not having a sore throat (p ≤ 0.005) were risk factors too. ConclusionFactors associated with death due to SARS caused by influenza in Brazil, risk factors and protective factors to death were identified. It was evident that those who did not receive the flu vaccine presented twice the risk of unfavorable outcome, reinforcing the need to stimulate adherence to vaccination adhering and propose changes in public policies to make influenza vaccines available to the entire population, in order to prevent severe cases and unfavorable outcomes.

Dental Enamel Alterations in Preschool Children from Salvador-Ba: Occurrence and Associated Factors

Objective: To describe the prevalence and distribution of Developmental Defects of Enamel (DDE) in children aged 3 to 5 years old in the city of Salvador-BA-Brazil, and to identify potential associated factors, considering socioeconomic, pregnancy, care characteristics childbirth and child behavior. Methodology: This cross-sectional study investigated the DDE in children aged 3 to 5 years, who attended municipal public daycare centers and Family Health Units, in 2018. The oral examination was carried out and it was applied a questionnaire to the respondent about characteristics of children and families. Descriptive and multivariate regression analyzes were performed, assuming a confidence level of 95%. Results: 1591 preschoolers were examined, with a mean age of 54 months. Most children were male (50.41%) and had brown or black skin color (93.34%). The prevalence of DDE was 9.24%. In the multivariate analysis, it was found that the male sex had a negative association with the DDE, while the age greater than or equal to 54 months and the presence of caries in the primary dentition showed a positive association with the DDE. Conclusion: DDEs are shown to be an important oral disease among preschoolage children to be monitored in the city of Salvador-BA, and strongly associated with dental caries.

Prevalence and correlates of meeting physical activity, screen time, and sleep duration guidelines among Brazilian adolescents: findings from ERICA.

The prevalence of meeting movement guidelines is low in developed countries; however, there is a lack of data among medium-income countries, including Brazil. We evaluated the prevalence and correlates of meeting physical activity, screen time, and sleep guidelines in Brazilian adolescents. Employing a cross-sectional design, Brazilian adolescents (aged 12-17years) were surveyed about their physical activity levels, sleep, and screen time. Data were collected at schools through a self-administered questionnaire using a personal digital assistant for entering the data. Poisson regression models were used to examine the associations between correlates (sex, age, socioeconomic status, region, skin colour, and shift of school) and meeting movement guidelines. A total of 58 535 adolescents were included. Although only 8.7% of the adolescents met all three movement guidelines, the prevalence of those who met physical activity, screen time, and sleep duration guidelines was 46.4%, 42.5%, and 40%, respectively. Moreover, male sex, age 14-15 years, black or brown skin colour, afternoon shift of school, and living in the Northern and Northeastern regions were associated with a higher prevalence of meeting all movement guidelines. The prevalence of adolescents who met all three movement guidelines was low among Brazilian adolescents. Adolescents living in less developed regions showed greater adherence to movement guidelines, suggesting a possible impact of the urbanization process on these behaviours. Novelty: The prevalence of Brazilian adolescents who met all three movement behaviour guidelines was around 9%. Among all adolescents, 40% met only one movement guideline.
