Sarcopenic Obesity in Portuguese Older Adults and Association With Cardiometabolic Outcomes and Mortality
The Berc-Luso project: Legislative, institutional, and educational impact evaluation
The Biomedical Ethics and Regulatory Capacity Building for Portuguese-Speaking African Countries Project (BERC-Luso) was a four-year project that aimed to enhance biomedical ethics and regulatory capacities in five Portuguese-Speaking African Countries (PSAC). BERC-Luso was developed considering the PSAC scarce number of clinical trials, exploring an untapped potential. The project's interventions focused on three primary areas: legislative, inst…

Socioeconomic factors and intergenerational differences in height of Portuguese adults born in 1990: Results from the Epiteen cohort
Average adult height is an indicator of population health and a marker of socioeconomic inequalities. This study aimed to assess how socioeconomic differences affect intergenerational height increase between adults born in 1990 and their parents. Data from a population-based cohort of subjects born in 1990 (EPITeen) were analysed. Participants’ adult height was objectively measured. Parental height, education, and occupation were reported by the …

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: A pooled analysis of 2181 population-based studies with 65 million p…
BACKGROUND: Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. METHODS: For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease …
Rising rural body-mass index is the main driver of the global obesity epidemic in adults
Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities 1,2 . This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity 3–6 . Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean B…

Prevalence of general and abdominal obesity in Portugal: Comprehensive results from the National Food, nutrition and physical activity survey 2015–2016
Almost 60% of the general Portuguese population is obese or pre-obese. Women, elderly and less educated individuals present the highest obesity prevalence. Abdominal obesity, in particular, seems to be a relevant public health problem among the elderly men
