The intersection of race/ethnicity and socioeconomic status: inequalities in breast and cervical cancer mortality in 20,665,005 adult women from the 100 Million Brazilian Cohort.

OBJECTIVES: There is limited evidence regarding the impact of race/racism and its intersection with socioeconomic status (SES) on breast and cervical cancer, the two most common female cancers globally. We investigated racial inequalities in breast and cervical cancer mortality and whether SES (education and household conditions) interacted with race/ethnicity. DESIGN: The 100 Million Brazilian Cohort data were linked to the Brazilian Mortality Database, 2004-2015 (n = 20,665,005 adult women). We analysed the association between self-reported race/ethnicity (White/'Parda'(Brown)/Black/Asian/Indigenous) and cancer mortality using Poisson regression, adjusting for age, calendar year, education, household conditions and area of residence. Additive and multiplicative interactions were assessed. RESULTS: Cervical cancer mortality rates were higher among Indigenous (adjusted Mortality rate ratio = 1.80, 95%CI 1.39-2.33), Asian (1.63, 1.20-2.22), 'Parda'(Brown) (1.27, 1.21-1.33) and Black (1.18, 1.09-1.28) women vs White women. Breast cancer mortality rates were higher among Black (1.10, 1.04-1.17) vs White women. Racial inequalities in cervical cancer mortality were larger among women of poor household conditions, and low education (P for multiplicative interaction <0.001, and 0.02, respectively). Compared to White women living in completely adequate (3-4) household conditions, the risk of cervical cancer mortality in Black women with 3-4, 1-2, and none adequate conditions was 1.10 (1.01-1.21), 1.48 (1.28-1.71), and 2.03 (1.56-2.63), respectively (Relative excess risk due to interaction-RERI = 0.78, 0.18-1.38). Among 'Parda'(Brown) women the risk was 1.18 (1.11-1.25), 1.68 (1.56-1.81), and 1.84 (1.63-2.08), respectively (RERI = 0.52, 0.16-0.87). Compared to high-educated White women, the risk in high-, middle- and low-educated Black women was 1.14 (0.83-1.55), 1.93 (1.57-2.38) and 2.75 (2.33-3.25), respectively (RERI = 0.36, -0.05-0.77). Among 'Parda'(Brown) women the risk was 1.09 (0.91-1.31), 1.99 (1.70-2.33) and 3.03 (2.61-3.52), respectively (RERI = 0.68, 0.48-0.88). No interactions were found for breast cancer. CONCLUSION: Low SES magnified racial inequalities in cervical cancer mortality. The intersection between race/ethnicity, SES and gender needs to be addressed to reduce racial health inequalities.

Neuroimaging findings in paediatric patients with sickle cell disease.

Sickle cell disease (SCD) is an autosomal recessive haemoglobinopathy, which manifests as multisystem ischaemia and infarction, as well as haemolytic anaemia. The morphological changes of red blood cells (RBCs) that promote ischaemia/infarction as the main multi-systemic manifestation, with associated vasculopathy, may also lead to haemorrhage and fat embolisation. Bone infarctions, whether of the skull or spine, are relatively common with subsequent increased infectious susceptibility. We present a broad spectrum of brain and spine imaging findings of SCD from a level III paediatric hospital in Lisbon, between 2010 and 2022. Our aim is to highlight brain and spine imaging findings from a serial review of multiple patients with SCD and respective neuroimaging characterisation.

Incidence of excess body weight and annual weight gain in women and men: Results from the ELSA-Brasil cohort.

OBJECTIVE: To estimate annual weight gain and the incidence of overweight and obesity, stratified according to gender and socioeconomic factors. METHODS: From the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), we included 13 625 women and men aged 35-74 (2008-2010) who attended a follow-up visit after a mean 3.8-years. Standardized questionnaires were used to record sociodemographic data, and height and weight were measured on all participants during in-person visits at research centers. The incidence rate to overweight was calculated among those not having excess weight at baseline, and incident obesity among those not having this condition at baseline. We evaluated the incidence of overweight and obesity in men and women, adjusted by age, through Poisson regression with robust variance. Large annual weight gain by gender was being defined as ≥90th percentile in the cohort. RESULTS: A global incidence of 7.7% for overweight and 10.6% for obesity was observed, with higher levels seen among black woman (28.5%), young men (21.1%) and woman with low educational level (35.0%). The proportions of overweight and obesity increased with age at both time points, more commonly among those with the lowest levels of per capita income and fewer years of schooling. Large annual weight gain was greater among participants with an intermediate level of education and those who self-identified as black. CONCLUSIONS: A high overall risk of becoming overweight/obese was found, especially among women. The roles of race and education level are fundamental to understanding the effects produced by social inequalities in rates of excess weight.

Effects of whole-body vibration on muscle strength, bone mineral content and density, and balance and body composition of children and adolescents with Down syndrome: a systematic review.

The aim of this study is to verify the effects of whole-body vibration (WBV) training on the muscle strength of children and adolescents with Down syndrome. We searched MEDLINE, Cochrane, SciELO, Lilacs and PUBMED databases and included manual searches to identify randomised controlled trials to investigate the effects of WBV on the structure and body function of children and adolescents with Down syndrome. Two reviewers independently selected the studies and performed statistical analysis. In total, five studies with 171 patients that compared WBV with exercise and/or control were included. Two studies demonstrated a significant difference between the muscle strength of children and adolescents with Down syndrome who received WBV training and that of those who did not receive the intervention. The studies included in this systematic review showed that WBV training has positive effects on bone mineral density (BMD), body composition and balance. Results of this study showed that WBV training improves muscle strength, BMD, body composition and balance of children and adolescents with Down syndrome, and a more in-depth analysis of its effects on other variables in this population is required, as well as of parameters to be used.

Postmenopausal hormone therapy in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil): who still uses it?

PURPOSE: We aim to investigate the patterns of hormone therapy (HT) use and associated factors in women participating in the Brazilian Longitudinal Study of Adult Health. METHODS: This study included 3281 naturally menopausal women of 40 to 74 years of age at enrollment to the Brazilian Longitudinal Study of Adult Health study, who answered questions regarding their use and discontinuation of HT. Prevalence rates of current and previous HT use were calculated, and a multinomial logistic regression model was constructed to simultaneously analyze the associated factors. RESULTS: The prevalence of HT use increased from 1995 onwards, peaking at 55.7% in 1997. A sharp decline occurred in the decade beginning in 2000, reaching 11.1% at the study baseline interview (2008-2010). Current use was associated with being ≥60 years of age (Relative Risk Ratio (RRR): 1.81; 95%CI: 1.10-2.96), divorced (RRR: 1.72; 95%CI: 1.14-2.60), or married (RRR: 2.09; 95%CI: 1.41-3.10); having a university education (RRR: 1.66; 95%CI: 1.14-2.40) or postgraduate degree (RRR: 2.45; 95%CI: 1.80-3.35); and having private health insurance (RRR: 2.86; 95%CI: 2.00-4.09). Body mass index ≥30 kg/m(2) was inversely associated with HT use (RRR: 0.37; 95%CI: 0.26-0.53) as was the presence of at least one contraindication to HT use (RRR: 0.63; 95%CI: 0.44-0.89). Of the current users ≥60 years of age, 79.1% had been using HT for at least 5 years, and 73.6% had been menopausal for at least 10 years. CONCLUSION: Although the use of HT has declined in Brazil, the women who continue using it are largely exceeding evidence-based limits of age, time since menopause, and time of use.

The effects of whole body vibration on mobility and balance in children with cerebral palsy: a systematic review with meta-analysis.

OBJECTIVE: We performed a meta-analysis to evaluate the effects of whole-body vibration on physiologic and functional measurements in children with cerebral palsy. DESIGN AND METHODS: We searched MEDLINE, Cochrane Controlled Trials Register, EMBASE, Scielo, CINAHL (from the earliest date available to November 2014) for randomized controlled trials, that aimed to investigate the effects of whole-body vibration versus exercise and/or versus control on physiologic and functional measurements in children with cerebral palsy. Two reviewers independently selected the studies. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated. RESULTS: Six studies with 176 patients comparing whole-body vibration to exercise and/or control were included. Whole-body vibration resulted in improvement in: gait speed WMDs (0.13 95% CI: 0.05 to 0.20); gross motor function dimension E WMDs (2.97 95% CI: 0.07 to 5.86) and femur bone density (1.32 95% CI: 0.28 to 2.36). The meta-analysis also showed a nonsignificant difference in muscle strength and gross motor function dimension D for participants in the whole-body vibration compared with control group. No serious adverse events were reported. CONCLUSIONS: Whole-body vibration may improve gait speed and standing function in children with cerebral palsy and could be considered for inclusion in rehabilitation programs.

Income Segregation, Conditional Cash Transfers, and Breast Cancer Mortality Among Women in Brazil.

Importance: Women living in income-segregated areas are less likely to receive adequate breast cancer care and access community resources, which may heighten breast cancer mortality risk. Objective: To investigate the association between income segregation and breast cancer mortality and whether this association is attenuated by receipt of the Bolsa Família program (BFP), the world's largest conditional cash-transfer program. Design, Setting, and Participants: This cohort study was conducted using data from the 100 Million Brazilian Cohort, which were linked with nationwide mortality registries (2004-2015). Data were analyzed from December 2021 to June 2023. Study participants were women aged 18 to 100 years. Exposure: Women's income segregation (high, medium, or low) at the municipality level was obtained using income data from the 2010 Brazilian census and assessed using dissimilarity index values in tertiles (low [0.01-0.25], medium [0.26-0.32], and high [0.33-0.73]). Main Outcomes and Measures: The main outcome was breast cancer mortality. Mortality rate ratios (MRRs) for the association of segregation with breast cancer deaths were estimated using Poisson regression adjusted for age, race, education, municipality area size, population density, area of residence (rural or urban), and year of enrollment. Multiplicative interactions of segregation and BFP receipt (yes or no) in the association with mortality (2004-2015) were assessed. Results: Data on 21 680 930 women (mean [SD] age, 36.1 [15.3] years) were analyzed. Breast cancer mortality was greater among women living in municipalities with high (adjusted MRR [aMRR], 1.18; 95% CI, 1.13-1.24) and medium (aMRR, 1.08; 95% CI, 1.03-1.12) compared with low segregation. Women who did not receive BFP had higher breast cancer mortality than BFP recipients (aMRR, 1.17; 95% CI, 1.12-1.22). By BFP strata, women who did not receive BFP and lived in municipalities with high income segregation had a 24% greater risk of death from breast cancer compared with those living in municipalities with low income segregation (aMRR, 1.24: 95% CI, 1.14-1.34); women who received BFP and were living in areas with high income segregation had a 13% higher risk of death from breast cancer compared with those living in municipalities with low income segregation (aMRR, 1.13; 95% CI, 1.07-1.19; P for interaction = .008). Stratified by the amount of time receiving the benefit, segregation (high vs low) was associated with an increase in mortality risk for women receiving BFP for less time but not for those receiving it for more time (<4 years: aMRR, 1.16; 95% CI, 1.07-1.27; 4-11 years: aMRR, 1.09; 95% CI, 1.00-1.17; P for interaction <.001). Conclusions and Relevance: These findings suggest that place-based inequities in breast cancer mortality associated with income segregation may be mitigated with BFP receipt, possibly via improved income and access to preventive cancer care services among women, which may be associated with early detection and treatment and ultimately reduced mortality.

Do social protection programmes affect the burden of breast and cervical cancer? A systematic review.

Background: Socioeconomic conditions are strongly associated with breast and cervical cancer incidence and mortality patterns; therefore, social protection programmes (SPPs) might impact these cancers. This study aimed to evaluate the effect of SPPs on breast and cervical cancer outcomes and their risk/protective factors. Methods: Five databases were searched for articles that assessed participation in PPS and the incidence, survival, mortality (primary outcomes), screening, staging at diagnosis and risk/protective factors (secondary outcomes) for these cancers. Only peer-reviewed quantitative studies of women receiving SPPs compared to eligible women not receiving benefits were included. Independent reviewers selected articles, assessed eligibility, extracted data, and assessed the risk of bias. A harvest plot represents the included studies and shows the direction of effect, sample size and risk of bias. Findings: Of 17,080 documents retrieved, 43 studies were included in the review. No studies evaluated the primary outcomes. They all examined the relationship between SPPs and screening, as well as risk and protective factors. The harvest plot showed that in lower risk of bias studies, participants of SPPs had lower weight and fertility, were older at sexual debut, and breastfed their infants for longer. Interpretation: No studies have yet assessed the effect of SPPs on breast and cervical cancer incidence, survival, or mortality; nevertheless, the existing evidence suggests positive impacts on risk and protective factors.

Delays in obtaining hospital care and abortion-related complications within a context of illegality.

Abortion, particularly when illegal, highlights inequities in different populations. Although abortion-related mortality is lower compared to other obstetric causes, abortion complications tend to be more lethal. Delays in seeking and obtaining care are determinants of negative outcomes. This study, nested within the GravSus-NE, analyzed healthcare delays and their association with abortion-related complications in three cities of northeastern Brazil (Salvador, Recife and São Luís). Nineteen public maternity hospitals were involved. All eligible women ≥18 years old hospitalized between August and December 2010 were evaluated. Descriptive, stratified and multivariate analyses were performed. Youden's index was used to determine delay. One model was created with all the women and another with those admitted in good clinical conditions, thus determining complications that occurred during hospitalization and their associated factors. Of 2,371 women, most (62.3%) were ≤30 years old (median 27 years) and 89.6% reported being black or brown-skinned. Most (90.5%) were admitted in good condition, 4.0% in fair condition and 5.5% in poor/very poor condition. Median time between admission and uterine evacuation was 7.9 hours. After a cut-off time of 10 hours, the development of complications increased considerably. Black women and those admitted during nightshifts were more likely to experience a wait time ≥10 hours. Delays were associated with severe complications (OR 1.97; 95%CI: 1.55-2.51), including in the women admitted in good condition (OR 2,56; 95%CI: 1.85-3.55), and even following adjustment for gestational age and reported abortion type (spontaneous/induced). These findings corroborate the literature, highlighting the social vulnerability of women hospitalized within Brazil's public healthcare system in a situation of abortion. The study strongpoints include having objectively measured the time between admission and uterine evacuation and having established a cut-off time defining delay based on conceptual and epidemiological criteria. Further studies should evaluate other settings and new measurement tools for effectively preventing life-threatening complications.

Working from home, work-time control and mental health: Results from the Brazilian longitudinal study of adult health (ELSA-Brasil).

This cross-sectional study investigated the association between work-time control (WTC), independently and in combination with hours worked (HW), and four mental health outcomes among 2,318 participants of the Longitudinal Study of Adult Health (ELSA-Brasil) who worked from home during the COVID-19 pandemic. WTC was assessed by the WTC Scale, and mental health outcomes included depression, anxiety, stress (measured by the Depression, Anxiety and Stress Scale, DASS-21), and self-rated mental health. Logistic regression models were used to determine odds ratios (ORs) and 95% confidence intervals (CIs). Among women, long HW were associated with stress (OR = 1.56; 95% CI = 1.11-2.20) and poor self-rated mental health (OR = 1.64; 95% CI = 1.13-2.38), whereas they were protective against anxiety among men (OR = 0.59; 95% CI = 0.37-0.93). In both sexes, weak WTC was associated with all mental health outcomes. Among women, the long HW/weak WTC combination was associated with all mental health outcomes, and short HW/weak WTC was associated with anxiety and stress. Among men, long HW/strong WTC was protective against depression and stress, while short HW/strong WTC and short HW/weak WTC was associated with all mental health outcomes. In both sexes, weak WTC, independently and in combination with HW, was associated with all mental health outcomes. WTC can improve working conditions, protect against mental distress, and fosterwork-life balance for those who work from home.

Magnetic and quasiparticle excitation spectra of an itinerant J1-J2 model for iron-pnictide superconductors.

We calculate the magnetic and quasiparticle excitation spectra of an itinerant J(1)-J(2) model for iron-pnictide superconductors. In addition to an acoustic spin-wave branch, the magnetic spectrum has a second, optical branch, resulting from the coupled four-sublattice magnetic structure. The spin-wave velocity has also a planar directional anisotropy, due to the collinear or striped antiferromagnetism. Within the magnetically ordered phase, the quasiparticle spectrum is composed of two Dirac cones, resulting from the folding of the magnetic Brillouin zone. We discuss the relevance of our findings to the understanding of both neutron scattering and photoemission spectroscopy results for SrFe(2)As(2).

Healthy lifestyle behaviors and the periodicity of mammography screening in Brazilian women.

INTRODUCTION: Certain behaviors have been associated with health promotion, including mammography screening, in women worldwide. OBJECTIVE: The objective of this study was to determine whether there is an association between the periodicity of mammography screening and healthy lifestyle behaviors in Brazilian women employed at a public university in Bahia, Brazil. METHODS: A total of 635 women of 50-69 years of age at the time of the interview, from the Brazilian Longitudinal Study of Adult Health cohort who were resident in Bahia, participated in the study. Data were collected using a multidimensional questionnaire that included questions on participants' sociodemographic characteristics and health-related behaviors (smoking, alcohol consumption, leisure-time physical activity and diet) and another questionnaire that dealt with risk factors and breast cancer screening. Measures of association were calculated using simple and multivariate logistic regression. RESULTS: The practice of physical activity, not smoking, moderate alcohol consumption and a healthy diet were the health behaviors most adopted by the women who had last had a mammogram ⩽2 years previously (which is in line with the interval recommended by the Brazilian Ministry of Health). A statistically significant association was found between a lapse of ⩾3 years since last undergoing mammography screening and excessive alcohol consumption, while a borderline association was found between the same screening interval and leisure-time physical inactivity. CONCLUSION: There was an association between lifestyle risk behaviors and a longer time interval between mammography screenings. The present results contribute to the debate on the use of mammography, lifestyle behaviors and health promotion among women.

Racial vulnerability and individual barriers for Brazilian women seeking first care following abortion. / Vulnerabilidade racial e barreiras individuais de mulheres em busca do primeiro atendimento pós-aborto.

Social inequalities in Brazil are reflected in women's search for abortion care, when they face individual, social, and structural barriers and are exposed to situations of vulnerability. Black women are the most heavily exposed to these barriers, from the search for the service to the care itself. The study aimed to analyze factors related to individual barriers in the search for first post-abortion care according to race/color. The study was conducted in Salvador (Bahia State), Recife, (Pernambuco State) and São Luís (Maranhão State), Brazil, with 2,640 patients admitted to public hospitals. Logistic regression was performed to analyze differences according to race/color (white, brown, and black), with "no individual barriers in the search for first care" as the reference category in the dependent variable. Of the women interviewed, 35.7% were black, 53.3% brown, and 11% white. Black women had less schooling, fewer children, and reported more induced abortions (31.1%) and more second-trimester abortions (15.4%). Black women reported more individual barriers in the search for first care (32% vs. 28% in brown women and 20.3% in whites), such as fear of being mistreated and lack of money for transportation. Regression analysis confirmed the association between black and brown race/color and individual barriers in the search for post-abortion care, even after adjusting for all the selected variables. The results confirmed the situation of vulnerability for black women and brown women in Brazil. Racial discrimination in health services and abortion-related stigma can act simultaneously, delaying women's access to health services, a limitation that can further complicate their post-abortion condition.

As desigualdades sociais no Brasil se refletem na busca por atenção pelas mulheres com abortamento, as quais enfrentam barreiras individuais, sociais e estruturais, expondo-as a situações de vulnerabilidades. São as negras as mais expostas a essas barreiras, desde a procura pelo serviço até o atendimento. O estudo objetivou analisar os fatores relacionados às barreiras individuais na busca do primeiro atendimento pós-aborto segundo raça/cor. A pesquisa foi realizada em Salvador (Bahia), Recife (Pernambuco) e São Luís (Maranhão), Brasil, com 2.640 usuárias internadas em hospitais públicos. Foi realizada regressão logística para análise das diferenças segundo raça/cor (branca, parda e preta), considerando-se "não houve barreiras individuais na busca pelo primeiro atendimento" como categoria de referência da variável dependente. Das entrevistadas, 35,7% eram pretas, 53,3% pardas e 11% brancas. Mulheres pretas tinham menor escolaridade, menos filhos e declararam mais o aborto como provocado (31,1%), após 12 semanas de gestação (15,4%). Relataram mais barreiras individuais na busca pelo primeiro atendimento (32% vs. 28% entre pardas e 20,3% entre brancas), tais como o medo de ser maltratada e não ter dinheiro para o transporte. Na regressão, confirmou-se a associação entre raça/cor preta e parda e barreiras individuais na busca de cuidados pós-aborto, mesmo após o ajuste por todas as variáveis selecionadas. Os resultados confirmam a situação de vulnerabilidade das pretas e pardas. A discriminação racial nos serviços de saúde e o estigma em relação ao aborto podem atuar simultaneamente, retardando a ida das mulheres ao serviço, o que pode configurar uma situação limite de maior agravamento do quadro pós-abortamento.

Las desigualdades sociales en Brasil se reflejan en la búsqueda de atención sanitaria por parte de las mujeres que abortan, que enfrentan barreras individuales, sociales y estructurales, exponiéndolas a situaciones de vulnerabilidad. Las negras son las más expuestas a estas barreras, desde la búsqueda del servicio hasta la atención. El estudio tuvo como objetivo analizar los factores relacionados con las barreras individuales en la búsqueda de la primera atención post-aborto según raza/color. La investigación se realizó en Salvador (Bahia), Recife (Pernambuco) y São Luis (Maranhão), Brasil, con 2.640 pacientes internadas en hospitales públicos. Se realizó una regresión logística para el análisis de las diferencias según raza/color (blanca, mulata/mestiza y negra), considerándose "no tuvo barreras individuales en la búsqueda de la primera atención" como categoría de referencia de la variable dependiente. De las entrevistadas 35,7% eran negras, 53,3% mulatas/mestizas y 11% blancas. Las mujeres negras tenían menor escolaridad, menos hijos y declararon más el aborto como provocado (31,1%), tras 12 semanas de gestación (15,4%). Informaron más barreras individuales en la búsqueda de la primera atención (32% vs. 28% entre multas/mestizas y un 20,3% entre las blancas), tales como el miedo de ser maltratada y no tener dinero para el transporte. En la regresión se confirmó la asociación entre raza/color negro y mulato/mestizo y barreras individuales en la búsqueda de cuidados post-aborto, incluso tras el ajuste por todas las variables seleccionadas. Los resultados confirman la situación de vulnerabilidad de las negras y mulatas/mestizas. La discriminación racial en los servicios de salud y el estigma en relación con el aborto pueden actuar simultáneamente, retardando la ida de las mujeres al servicio de salud, lo que puede constituir una situación límite de mayor gravedad en el cuadro post-aborto.

Quality assessment of abortion care from the users' perspective: dimensional structure of the QualiAborto-Pt questionnaire. / Avaliação da qualidade da atenção ao aborto na perspectiva das usuárias: estrutura dimensional do instrumento QualiAborto-Pt.

Abortion complications are a major public health problem, and studies to assess the quality of abortion care require adequate measurement tools. This study is a continuation of such an instrument's refinement, the QualiAborto-Pt questionnaire. Using data from a survey of 2,336 women hospitalized for abortion complications in 19 hospitals in three state capitals in Northeast Brazil (Salvador - Bahia, Recife - Pernambuco, and São Luís - Maranhão), we implemented a series of exploratory and confirmatory factor analyses based on a 55-item prototype. The analyses indicate a structure with 17 items in five dimensions: reception, orientation, inputs/physical environment, technical quality, and continuity of care. All the items in the final model displayed acceptable reliability, absence of content redundancy, and factor specificity, as well as theoretical consistency with the respective dimensions. The solution also shows discriminant factor validity. Despite some persistent issues for further analysis and clarification, this version merits recommendation for use in Brazil.

As complicações do aborto são um importante problema de saúde pública e pesquisas para avaliar a qualidade da atenção requerem ferramentas de aferição adequadas. Este estudo dá sequência ao processo de refinamento de um instrumento para esse fim - QualiAborto-Pt. Utilizando-se dados de um inquérito com 2.336 mulheres internadas por complicações do aborto em 19 hospitais de três capitais do Nordeste brasileiro (Salvador - Bahia, Recife - Pernambuco e São Luís - Maranhão), implementou-se uma sequência de análises fatoriais exploratórias e confirmatórias com base em um protótipo de 55 itens. As análises apontam para uma estrutura de 17 itens em cinco dimensões: acolhimento, orientação, insumos/ambiente físico, qualidade técnica e continuidade do cuidado. Todos os itens do modelo final evidenciam confiabilidade aceitável, ausência de redundância de conteúdo, especificidade fatorial, e guardam coerência teórica com as respectivas dimensões. A solução também mostra validade fatorial discriminante. Ainda que persistam algumas questões a aprofundar e acertar, esta versão merece ser recomendada para uso no Brasil.

Virgin Coconut Oil Supplementation Prevents Airway Hyperreactivity of Guinea Pigs with Chronic Allergic Lung Inflammation by Antioxidant Mechanism.

Asthma is a chronic inflammatory disease of the airways characterized by immune cell infiltrates, bronchial hyperresponsiveness, and declining lung function. Thus, the possible effects of virgin coconut oil on a chronic allergic lung inflammation model were evaluated. Morphology of lung and airway tissue exhibited peribronchial inflammatory infiltrate, epithelial hyperplasia, and smooth muscle thickening in guinea pigs submitted to ovalbumin sensitization, which were prevented by virgin coconut oil supplementation. Additionally, in animals with lung inflammation, trachea contracted in response to ovalbumin administration, showed a greater contractile response to carbachol (CCh) and histamine, and these responses were prevented by the virgin coconut oil supplementation. Apocynin, a NADPH oxidase inhibitor, did not reduce the potency of CCh, whereas tempol, a superoxide dismutase mimetic, reduced potency only in nonsensitized animals. Catalase reduced the CCh potency in nonsensitized animals and animals sensitized and treated with coconut oil, indicating the participation of superoxide anion and hydrogen peroxide in the hypercontractility, which was prevented by virgin coconut oil. In the presence of L-NAME, a nitric oxide synthase (NOS) inhibitor, the CCh curve remained unchanged in nonsensitized animals but had increased efficacy and potency in sensitized animals, indicating an inhibition of endothelial NOS but ineffective in inhibiting inducible NOS. In animals sensitized and treated with coconut oil, the CCh curve was not altered, indicating a reduction in the release of NO by inducible NOS. These data were confirmed by peribronchiolar expression analysis of iNOS. The antioxidant capacity was reduced in the lungs of animals with chronic allergic lung inflammation, which was reversed by the coconut oil, and confirmed by analysis of peribronchiolar 8-iso-PGF2α content. Therefore, the virgin coconut oil supplementation reverses peribronchial inflammatory infiltrate, epithelial hyperplasia, smooth muscle thickening, and hypercontractility through oxidative stress and its interactions with the NO pathway.

Health behavior-related indicator of lifestyle: application in the ELSA-Brasil study.

Various behaviors are considered health enhancing. Nevertheless, according to the current scientific literature, four health behaviors are considered particularly risky in view of their association with a group of chronic diseases: 1) smoking; 2) excessive alcohol consumption; 3) poor diet; and 4) lack of physical activity. Theoretically, it should be possible to make improvements to one's health by maximizing the number of healthy behaviors and minimizing the unhealthy ones. However, in reality, the different behaviors interconnect to create more complex lifestyles. Therefore, the objective of this paper is to present the construction of a lifestyle indicator based on health behaviors selected in the ELSA-Brazil study. This indicator revealed two lifestyles: less healthy and healthier lifestyles. The model proved adequate and was confirmed using latent class analysis (LCA). Agreement was 83.2 between the indicator and the LCA results, with a kappa coefficient of 0.65. Women were more likely to have a healthier lifestyle than men, reinforcing the scientific consistency of the indicator, since this finding is in agreement with data from the scientific literature. The indicator created to define lifestyle was found to have scientific consistency and validity; therefore, its use can be recommended for future population-based studies concerning the promotion of health and healthy lifestyles.

Sex differences and correlates of poor glycaemic control in type 2 diabetes: a cross-sectional study in Brazil and Venezuela.

OBJECTIVE: Examine whether glycaemic control varies according to sex and whether the latter plays a role in modifying factors associated with inadequate glycaemic control in patients with type 2 diabetes (T2D) in Brazil and Venezuela. DESIGN, SETTING AND PARTICIPANTS: This was a cross-sectional, nationwide survey conducted in Brazil and Venezuela from February 2006 to June 2007 to obtain information about glycaemic control and its determinants in patients with diabetes mellitus attending outpatient clinics. MAIN OUTCOME MEASURES: Haemoglobin A1c (HbA1c) level was measured by liquid chromatography, and patients with HbA1c ≥7.0% (53 mmol/mol) were considered to have inadequate glycaemic control. The association of selected variables with glycaemic control was analysed by multivariate linear regression, using HbA1c as the dependent variable. RESULTS: A total of 9418 patients with T2D were enrolled in Brazil (n=5692) and in Venezuela (n=3726). They included 6214 (66%) women and 3204 (34%) men. On average, HbA1c levels in women were 0.13 (95% CI 0.03 to 0.24; p=0.015) higher than in men, after adjusting for age, marital status, education, race, country, body mass index, duration of disease, complications, type of healthcare, adherence to diet, adherence to treatment and previous measurement of HbA1c. Sex modified the effect of some factors associated with glycaemic control in patients with T2D in our study, but had no noteworthy effect in others. CONCLUSIONS: Women with T2D had worse glycaemic control than men. Possible causes for poorer glycaemic control in women compared with men include differences in glucose homeostasis, treatment response and psychological factors. In addition, sex modified factors associated with glycaemic control, suggesting the need to develop specific treatment guidelines for men and women.

Association between leisure-time physical activity and sedentary behavior with cardiometabolic health in the ELSA-Brasil participants.

OBJECTIVES: To assess associations, both individually and in combination, between leisure-time physical activity and sedentary behavior, and cardiometabolic health. METHODS: This cross-sectional study included 13,931 civil servants participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Leisure-time physical activity was analyzed using the leisure-time domain of the long-form International Physical Activity Questionnaire, while questions related to cumulative sitting time and leisure-based screen time on a weekday and on one day on the weekend were used to establish sedentary behavior. Data analysis was performed using multivariate logistic regression. RESULTS: Following adjustment for confounding variables, high levels of leisure-time physical activity and low levels of sedentary behavior were both associated with favorable cardiometabolic health markers in both genders. When these two factors were analyzed in conjunction, taking the combination of low levels of leisure-time physical activity and high levels of sedentary behavior as the reference, the inverse associations with cardiometabolic variables became even more significant. CONCLUSION: High levels of leisure-time physical activity and low levels of sedentary behavior were both inversely associated with the cardiometabolic variables analyzed; however, the two variables when evaluated in conjunction appear to produce more consistent associations, particularly when sedentary behavior is evaluated according to leisure-based screen time.

Delays in access to care for abortion-related complications: the experience of women in Northeast Brazil.

Around 18 million unsafe abortions occur in low and middle-income countries and are associated with numerous adverse consequences to women's health. The time taken by women with complications to reach facilities where they can receive appropriate post-abortion care can influence the risk of death and the extent of further complications. All women aged 18+ admitted for abortion complications to public-sector hospitals in three capital cities in the Northeastern Brazil between August-December 2010 were interviewed; medical records were extracted (N = 2,804). Nearly all women (94%) went straight to a health facility, mainly to a hospital (76.6%); the rest had various care-seeking paths, with a quarter visiting 3+ hospitals. Women waited 10 hours on average before deciding to seek care. 29% reported difficulties in starting to seek care, including facing challenges in organizing childcare, a companion or transport (17%) and fear/stigma (11%); a few did not initially recognize they needed care (0.4%). The median time taken to arrive at the ultimate facility was 36 hours. Over a quarter of women reported experiencing difficulties being admitted to a hospital, including long waits (15%), only being attended after pregnant women (8.9%) and waiting for a bed (7.4%). Almost all women (90%) arrived in good condition, but those with longer delays were more likely to have (mild or severe) complications. In Brazil, where access to induced abortion is restricted, women face numerous difficulties receiving post-abortion care, which contribute to delay and influence the severity of post-abortion complications.

What Factors Explain Bicycling and Walking for Commuting by ELSA-Brasil Participants?

PURPOSE: To analyze the factors associated with commuting by bicycling and walking in adult participants from ELSA-Brasil (Longitudinal Study of Adult Health). DESIGN: Cross-sectional. SETTING: Six teaching/research institutions throughout Brazil. PARTICIPANTS: A total of 15 105 civil servants. MEASURES: Commuting by bicycling and walking was analyzed using the long-form International Physical Activity Questionnaire. ANALYSIS: A hierarchical model containing possible factors associated with commuting by bicycling and walking was constructed. Crude and adjusted odds ratios were calculated using multinomial logistic regression. RESULTS: Considering the 2 forms of commuting, 66% of the participants were being considered inactive or insufficiently active. In women, being "heavier," feeling unsafe practicing physical activity, and being a former smoker were factors negatively associated with commuting by bicycling and walking. In men, active commuting was less common among those who were overweight or had abdominal obesity, those with a negative perception of safety, and those reporting that there was nowhere suitable in the neighborhood to practice physical activity. CONCLUSION: Obesity and negative perceptions in the neighborhood are associated with inactive or insufficiently active commuting. The relevance of this finding for public health is reinforce developing policies aimed at promoting health in Brazil and in other countries with similar characteristics.
