“…For countries with a low-or middle-human development index (HDI), greater household income was positively associated with risk, while for high HDI countries the opposite occurred. 18 Further, in multiethnic societies, much of the increased risk for obesity attributed to race or ethnicity disappears after adjustment for household/district income. 19 In Colombia, national examination surveys carried out in 2005, 2010 and 2015 have provided limited information on the distribution of obesity-related risk factors, and no data on the prevalence of central obesity.…”

Objective: Latin American countries are experiencing a nutritional and demographic transition that predisposes to the spread of the obesity epidemic, especially among the socially and economically disadvantaged. We aimed to describe the prevalence of obesity, overweight and abdominal obesity and their association with household socioeconomic status (SES) and personal educational level in the five major cities of Colombia (Bogotá, Medellín, Cali, Barranquilla and Bucaramanga). Materials and Methods: We collected demographic and anthropometric measurements from a population-based, stratified, multi-stage probability sample of individuals aged 2-75 years. Study surveys and anthropometric measurements were administered by highly trained staff. All reported prevalences are expanded to the target population, taking into account the sampling design. Results: The study sample included 1922 participants. In children and adolescents, the prevalence of overweight and obesity were respectively 23% and 8.8%. Overweight was most prevalent in the 2-4 (30.9%), followed by the 5-11 (23.8%) and the 12-17 age group (17.8%). The combined prevalence of childhood overweight and obesity increased with SES (16.8% in the lowest vs 42.8% in the highest stratum). In adults (18-75 years), the prevalence of excess body weight was 57.5% (36.2% overweight, 21.3% obesity), the prevalence of abdominal obesity was 34.4%, all prevalences increased with age. Obesity was far more prevalent among adult women (29.4%) than men (12.6%) (p˂0.001). Adult obesity and abdominal obesity decreased significantly and monotonically with SES and were most prevalent in individuals with the lowest educational level (35.3% and 50.7%, respectively). Almost 40% of overweight adults had abdominal obesity. Conclusion: Obesity and abdominal obesity are highly prevalent in the urban population of Colombia, and much more frequent among adults of lower SES and educational level. Excess body weight affected more often children of higher SES. Public health measures are urgently needed to tackle the spread of the obesity epidemic in Colombia and other Latin American countries, with a focus on low-income and low-educational level segments of society.

In the last few years, a significant increase of childhood obesity incidence unequally distributed within countries and population groups has been observed, thus representing an important public health problem associated with several health and social consequences. Obese children have more than a 50% probability of becoming obese adults, and to develop pathologies typical of obese adults, that include type 2-diabetes, dyslipidemia and hypertension. Also environmental factors, such as reduced physical activity and increased sedentary activities, may also result in increased caloric intake and/or decreased caloric expenditure. In the present review, we aimed to identify and describe a specific panel of parameters in order to evaluate and characterize the childhood obesity status useful in setting up a preventive diagnostic approach directed at improving health-related behaviors and identifying predisposing risk factors. An early identification of risk factors for childhood obesity could definitely help in setting up adequate and specific clinical treatments.

“…The use of a standardized and rigorous measurement protocol, robust data quality assurance procedures, and the training and certification of research staff ensured that the data collected at all sites were of high quality. Finally, all anthropometric (Katzmarzyk et al, 2019) and accelerometry (Katzmarzyk et al, 2019;Tudor-Locke et al, 2015) data were directly measured.…”

“…HDI, a composite measure of key dimensions of human development (ie, life expectancy at birth, mean years of schooling, and gross national income per capita) can be used as a cross‐country indicator to demonstrate implications of national policy priorities (United Nations Development Programme, ). HDI has been shown to be differentially associated with prevalences of childhood obesity (Katzmarzyk et al, ; Lissner et al, ) and physical activity levels (Katzmarzyk et al, ). Documenting global socioeconomic inequalities in childhood obesity and related factors has public health implications for the development of universal or targeted prevention strategies (Lissner et al, ).…”

Objective This study describes the distributions of body mass index (BMI) and movement behaviors among schoolchildren from 13 countries across a continuum of human development. Methods Data were from a cross‐sectional study of 9‐11‐year‐old children (n = 8055) recruited from 269 urban schools in 13 countries, and an additional 7 rural schools in one of these countries (Mozambique). BMI was derived from objectively measured heights and weights. Moderate‐ to vigorous‐intensity physical activity (MVPA), sedentary time (SED), and sleep duration were assessed by waist‐worn Actigraph GT3X+ accelerometers. Linear models were used to describe the distributions of BMI z‐scores, MVPA, SED, and sleep among sites across varying Human Development Indices (HDIs). Results Mean MVPA, SED, and sleep duration were 63.1 ± 27.3 minutes/day, 508.7 ± 72.4 minutes/day, and 8.8 ± 0.9 hours/night, respectively. Overall, 2.1% of the sample were thin, 19.5% overweight, and 11.7% were obese. Density curves (BMI z‐scores and SED) for urban children in Mozambique showed significantly higher mean values compared with rural children. Boys had significantly higher mean MVPA compared with girls. Mean BMI z‐scores were positively associated (β = .02; P = .004) with HDI, mean daily MVPA minutes were negatively associated (β = −.38; P = .025) with HDI, and mean SED time was positively associated with HDI (β = 1.18; P = .049). No significant association (β = .01; P = .29) was observed between sleep duration and HDI. Conclusion Our findings show distinct differences in BMI and movement behavior profiles between urban and rural children in Mozambique. Mean BMI z‐scores, MVPA, and SED differed by country HDI. These findings support the need to include both rural and urban participants in study samples.
