This international longitudinal study compared before during pandemic. Methods Parents of children aged 3–5 years, from 14 countries (8 low- middle-income countries, LMICs) completed surveys assess how these were Surveys 12 months up...
Importance The prevalence estimates of physical activity, sedentary behavior, and sleep (collectively known as movement behaviors) in 3- 4-year-old children worldwide remains uncertain. Objective To report the proportion who met World Health Organization guidelines for across 33 countries.

Thirty-three countries varying...
24-hour movement behaviours (physical activity, sedentary behaviour and sleep) during the early years are associated with health developmental outcomes, prompting WHO to develop Global guidelines for physical sleep children under 5 of age. Prevalence data on is lacking, particularly in low-income middle-income countries (LMICs). This paper describes development
ABSTRACT Purpose There is a paucity of global data on sedentary behavior during early childhood. The purpose this study was to examine how device-measured in young children differed across geographically, economically, and sociodemographically diverse populations, an international sample. Methods This multinational, cross-sectional included from 1071 3–5 yr old 19 countries, collected between 2018 2020 (pre-COVID). Sedentary measured for three consecutive days using activPAL accelerometers....
Abstract Background: The 2020 COVID-19 pandemic has placed unprecedented restrictions on children’s ability to participate in adequate movement behaviours. This international longitudinal study compared young physical activity, sedentary behaviour and sleep behaviours before during the pandemic. Methods: Parents of children aged 3-5 years, from 14 countries (8 low- middle-income countries, LMICs) completed surveys assess changes (screen-time) how these were associated with Surveys 12 months...
Abstract Background Hepatitis B virus (HBV) vaccination in Vietnamese adults remains low and unequally distributed. We conducted a study on HBV-naïve living Ho Chi Minh City, Viet Nam, to determine barriers associated with HBV uptake after removing the financial barrier by providing free coupons for vaccination. Methods After being screened HBsAg, anti-HBs, anti-HBc, 284 participants aged 18 over (i.e., negative anti-HBc total) were provided 3-dose vaccine coupons. Next, participants’...

Childhood overweight and obesity are becoming more pronounced in Vietnam, so an assessment tool of high efficiency the community is warranted. This study sought to validate skinfold thickness (SFT) equations for estimation body fatness by Goran Slaughter against DXA aid assessing obesity. A cross-sectional was conducted on 144 healthy children (ages 6-17) who were conveniently sampled from schools within urban district. Their anthropometric measurements (height, weight, SFT) whole-body...
