“…This diversity is reflected in the educational and socioeconomic distribution captured in ELSA-Brasil, where 19% were manual workers, 46% were in a middle socio-occupational category, and 38% were in a higher socio-occupational category, representing managerial or professional occupations. 42 Similarly, 12% were in the low-income category, and nearly 40% were in the middle-income category. Moreover, less than half had a university degree, with 34% with a high school education and 10% with an elementary school education or less.…”

“…National assessments indicate that the lower and middle classes represent 20% and 65% of the population, respectively. 42 Therefore, while like other cohort studies, ELSA-Brasil does not include a fully representative sample of Brazilian adults, it includes a wide range of socioeconomic, educational and occupational classes. To further address the potential limitations in generalisability, we identified persistent overprediction of risk across educational categories, arguing against differences between individuals in our study cohort and the general population.…”

AimsDespite notable population differences in high-income and low- and middle-income countries (LMICs), national guidelines in LMICs often recommend using US-based cardiovascular disease (CVD) risk scores for treatment decisions. We examined the performance of widely used international CVD risk scores within the largest Brazilian community-based cohort study (Brazilian Longitudinal Study of Adult Health, ELSA-Brasil).MethodsAll adults 40–75 years from ELSA-Brasil (2008–2013) without prior CVD who were followed for incident, adjudicated CVD events (fatal and non-fatal MI, stroke, or coronary heart disease death). We evaluated 5 scores—Framingham General Risk (FGR), Pooled Cohort Equations (PCEs), WHO CVD score, Globorisk-LAC and the Systematic Coronary Risk Evaluation 2 score (SCORE-2). We assessed their discrimination using the area under the receiver operating characteristic curve (AUC) and calibration with predicted-to-observed risk (P/O) ratios—overall and by sex/race groups.ResultsThere were 12 155 individuals (53.0±8.2 years, 55.3% female) who suffered 149 incident CVD events. All scores had a model AUC>0.7 overall and for most age/sex groups, except for white women, where AUC was <0.6 for all scores, with higher overestimation in this subgroup. All risk scores overestimated CVD risk with 32%–170% overestimation across scores. PCE and FGR had the highest overestimation (P/O ratio: 2.74 (95% CI 2.42 to 3.06)) and 2.61 (95% CI 1.79 to 3.43)) and the recalibrated WHO score had the best calibration (P/O ratio: 1.32 (95% CI 1.12 to 1.48)).ConclusionIn a large prospective cohort from Brazil, we found that widely accepted CVD risk scores overestimate risk by over twofold, and have poor risk discrimination particularly among Brazilian women. Our work highlights the value of risk stratification strategies tailored to the unique populations and risks of LMICs.

“…The number of dimensions was chosen by analysing the decline in eigenvalues using scree plot. Dendrograms were performed (graphic representations of hierarchical cluster analysis) with the coordinates obtained in the MCA to determine the clusters, providing clear visualization of the categories of variables in each group [ 31 ]. Scatterplots were formed by the coordinates of each category in each dimension, and clusters of categories were used to identify factors associated with body shape trajectories.…”

Background Evaluating lifelong weight trajectories is challenging due to the high costs of studies that follow individuals from childhood to adulthood. The use of silhouette scales has been a new approach to assess the body shape trajectory across life as a proxy for body weight trajectory. Depending on body shape trajectories, individuals may be more prone to develop diseases in adulthood. Therefore, identifying factors related to them is essential for public health. This study aimed to evaluate body shape trajectories across the lifespan and to verify associations between them, birth weight, body mass index, and sociodemographic conditions in a Brazilian cohort. Methods This is a cross-sectional analysis conducted with 14,014 participants of first follow-up data collection of Longitudinal Study of Adult Health (ELSA-Brasil). ELSA-Brasil is a multicentric prospective cohort study initiated in 2008 with civil servants of six public institutions in the Northeast, South and Southeast regions of Brazil. We applied a clustering method to longitudinal data to identify body shape trajectories from 5 to 40 years of age and assessed the associations between these trajectories and birth weight, body mass index and sociodemographic conditions (race, education, maternal education and monthly per capita family income) using multiple correspondence analysis. Results We found five body shape trajectories for women and three for men. Low birth weight was associated with a slight to moderate increase in shape. High birth weight was associated with maintaining large body size in both sexes and markedly increased body shape in women. Higher sociodemographic status and white race were associated with marked increases in body shape in men and maintenance of medium body shape in women. Conclusions The study shows that variables related to worse lifetime weight status (evaluated by anthropometry), such as presence of obesity, are also associated with worse body shape trajectories, as assessed with silhouette scales. Our results suggest that body shape trajectories are a good indicator of body weight trajectories and may be used when cohort studies are not possible.
