The intersection of race/ethnicity and socioeconomic status
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
Non-communicable diseases in sub-Saharan Africa
BACKGROUND: Non-communicable diseases (NCDs) cause a large and growing burden of morbidity and mortality in sub-Saharan Africa. Prospective cohort studies are key to study multiple risk factors and chronic diseases and are crucial to our understanding of the burden, aetiology and prognosis of NCDs in SSA. We aimed to identify the level of research output on NCDs and their risk factors collected by cohorts in SSA. METHODS: We conducted a scoping r…
Sobrerrastreio mamográfico
No Brasil, o Ministério da Saúde recomenda o rastreamento mamográfico bienal para mulheres entre 50-69 anos. Como o rastreamento é oportunístico no país, a periodicidade efetiva varia. Esse estudo visou a testar metodologia para a estimação do sobrerrastreio por periodicidade excessiva, definido como intervalo entre exames menores que o preconizado e sua associação com variáveis sociodemográficas. Trata-se de uma coorte de mulheres com mamografia…
Inequities in access to mammographic screening in Brazil
Our objectives with this study were to describe the spatial distribution of mammographic screening coverage across small geographical areas (micro-regions) in Brazil, and to analyze whether the observed differences were associated with spatial inequities in socioeconomic conditions, provision of health care, and healthcare services utilization. We performed an area-based ecological study on mammographic screening coverage in the period of 2010-20…
Association of BMI with overall and cause-specific mortality
Background BMI is known to be strongly associated with all-cause mortality, but few studies have been large enough to reliably examine associations between BMI and a comprehensive range of cause-specific mortality outcomes. Methods In this population-based cohort study, we used UK primary care data from the Clinical Practice Research Datalink (CPRD) linked to national mortality registration data and fitted adjusted Cox regression models to examin…
Políticas de controle do câncer de mama no Brasil
Acesso à detecção precoce do câncer de mama no Sistema Único de Saúde
A redução recente na mortalidade por câncer de mama em países de alta renda é atribuída à detecção precoce e melhorias no tratamento. O câncer de mama é o tipo mais frequente de câncer feminino no Brasil, e, desde 2004, o governo recomenda o exame clínico anual das mamas para mulheres a partir dos 40 anos e rastreio mamográfico bienal entre 50 e 69 anos. Este artigo investiga o nível de implementação dessas recomendações usando os dados dos siste…
Sample selection and validity of exposure–disease association estimates in cohort studies
BACKGROUND: Participants in cohort studies are frequently selected from restricted source populations. It has been recognised that such restriction may affect the study validity. OBJECTIVES: To assess the bias that may arise when analyses involve data from cohorts based on restricted source populations, an area little studied in quantitative terms. METHODS: Monte Carlo simulations were used, based on a setting where the exposure and one risk fact…
Validity and reproducibility of a semi-quantitative food frequency questionnaire for use among Portuguese pregnant women
This study aimed to evaluate the validity and reproducibility of a semi-quantitative food frequency questionnaire (FFQ) to estimate nutrient intake among Portuguese pregnant women. A sample of 101 pregnant women completed a 3-day food diary (FD) in each pregnancy trimester (reference method) and an interviewer-administered FFQ in the immediate post-partum period. Ranking women according to their usual intake showed that, on average, 65% were clas…
Dietary intake and nutritional adequacy prior to conception and during pregnancy
Objective To assess maternal diet and nutritional adequacy prior to conception and during pregnancy. Design Follow-up of a cohort of pregnant women with collection of questionnaire data throughout pregnancy and after delivery. Setting Antenatal clinics at two public hospitals in Porto, Portugal. Subjects Two hundred and forty-nine pregnant women who reported a gestational age below 13 weeks at the time they attended their first antenatal visit. R…
