Sleep Duration and Sun Exposure in Portuguese Children
Neighborhood Social Fragmentation and Excessive Body Weight Among Children—A View From a Portuguese Inner City
This cross‐sectional study examined the association between neighborhood social fragmentation and excessive body weight in childhood. The sample included 832 children aged 3–10 years living in the municipality of Porto, Portugal. Excessive body weight was classified using International Obesity Task Force sex‐ and age‐specific cut‐offs. Neighborhood social fragmentation was assessed using a composite index derived from 2021 Portuguese Census data …
Device-specific and contextual patterns of screen use
While most research emphasizes the negative impact of screen time duration on child outcomes, fewer studies examine how content, context, and device-specific patterns influence mental health in early childhood. This study explored how characteristics of household screen media use, including dominant content type, device, co-viewing frequency, and age at first exposure, relate to socio-emotional outcomes in children aged 2–6 years. Cross‐sectional…

Perceptions of neighborhood environments and childhood obesity
Body size and obesity patterns in Caboclo populations from Pará, Amazonia, Brazil
The results suggest an effect of increased Western lifestyle influence on the body composition of these Caboclo populations. Considering that these are rural populations with limited access to education and health care, the high prevalence of overweight and obesity associated with low socio-economic status makes them a vulnerable group that deserves a higher level of attention by the country's public health authorities

Environmental and Socio-demographic Factors Associated with 6–10-Year-Old Children’s School Travel in Urban and Non-urban Settings
Changes in stature of Portuguese women born between 1966 and 1982, according to educational level
Studies which document secular change in stature are almost exclusively based on males, while similar data on females is less common.

Changes in height, weight, BMI and in the prevalence of obesity among 9- to 11-year-old affluent Portuguese schoolboys, between 1960 and 2000
The results suggest that a high family income does not necessarily translate into more informed choices about healthy foods and lifestyles, with a strong influence in the prevalence of obesity. This pattern of association between socio-economic status and obesity may reflect a late socio-economic transition of Portugal, compared to that of other high-income countries
Height and relative leg length as indicators of the quality of the environment among Mozambican juveniles and adolescents
The growth status of Mozambique adolescents was assessed to test the hypothesis that relative leg length is a more sensitive indicator of the quality of the environment than the total height. The sample comprised 690 boys and 727 girls, aged between 9 and 17 years, from Maputo. It is divided between those living in the Centre of Maputo and those living in the slums on the periphery of the city. Height, weight, and sitting height were measured and…
