Article Synopsis
- This study investigates how following 24-hour movement guidelines (which include physical activity, sedentary behavior, and sleep) impacts body fat percentage in Asian adolescents across eight major cities.
- Researchers collected data from over 12,000 adolescents, finding that levels of compliance with these guidelines varied significantly from city to city.
- The results indicate that meeting more of the movement guidelines is associated with lower body fat percentages, suggesting that adherence to these guidelines could support healthier body weight in young people.
Moderate-to-vigorous physical activity attenuates the detrimental effects of television viewing on the cardiorespiratory fitness in Asian adolescents: the Asia-fit study.

Article Synopsis
- The study investigates the relationship between moderate-to-vigorous physical activity (MVPA) and television watching on cardiorespiratory fitness in young Asian adolescents, an area with limited research.
- Conducted among 9,553 adolescents aged 12-15 from eight Asian cities, the research utilized the PACER test for fitness assessment and the International Physical Activity Questionnaire to gauge MVPA and TV time.
- Results showed that higher levels of MVPA (≥60 min/day) significantly improve fitness scores, even if adolescents watch more TV, while less active girls who watched less TV had better fitness than those in the most sedentary group.
Article Synopsis
- The study examined physical activity (PA) and health-related fitness among 12,590 Asian adolescents from eight metropolitan cities, focusing on how well they met PA guidelines and fitness standards.
- Results indicated significant variations in PA levels and fitness performance across different cities, as well as different percentages of adolescents meeting recommended PA guidelines and achieving Healthy Fitness Zone (HFZ) standards for aerobic capacity and muscular fitness.
- Importantly, meeting PA guidelines was linked to higher chances of reaching HFZs in aerobic and muscular fitness, though there was no significant connection with body composition HFZ.
Objective: Explore the association between physically active behavior and obesity in 7- to 12-years-old Thai children.
Material And Method: As part of SEANUTS Thailand, information on anthropometry, physical activity, and sociodemographic variables were collected in 7- to 12-years-old urban and rural Thai children. Multi-stage sampling technique was used and 1,345 children (32% urban, and 50.
Background: Several studies on Caucasian volunteers have proven that milk is an effective recovery drink for athletes. Such benefit, however, cannot be directly applied to the lactose-intolerant Asian population. This study investigated the effects of ingesting water (WT), sports drink (SPD) and lactose-free milk (LFM) on cycling capacity.

Material And Method: Fifty-one healthy Thai adolescents (25 males and 26 females) aged 16 to 19 years volunteered in the present study. Underwater weighing (UWW) and dual energy X-ray absorptiometry (DEXA) were used for measurement of %BF for 2C and 3C models.
In the present study, we investigated nutritional status and health-related factors in a multistage cluster sample of 3119 Thai urban and rural children aged 0·5-12·9 years. In a subsample, blood samples were collected for the measurement of Hb, transferrin receptor, vitamin A and vitamin D concentrations. The prevalence of stunting and underweight was higher in rural children than in urban children, whereas the wasting rate was similar in both rural and urban areas.
View Article and Find Full Text PDFOverweight and obesity in Asian children are increasing at an alarming rate; therefore a better understanding of the relationship between BMI and percentage body fat (%BF) in this population is important. A total of 1039 children aged 8-10 years, encompassing a wide BMI range, were recruited from China, Lebanon, Malaysia, The Philippines and Thailand. Body composition was determined using the 2H dilution technique to quantify total body water and subsequently fat mass, fat-free mass and %BF.

However few data are available on differences in fat distribution in Asian children from various backgrounds. Therefore, the current study aimed to explore ethnic differences in body fat distribution among Asian children from four countries.
View Article and Find Full Text PDFObjective: To compare waist circumference (WC) measured at different sites of trunk region and to determine predictive WC values that were corresponding to weight-for-height index in Thai adolescents.
Material And Method: The authors conducted the cross-sectional study in 509 adolescents, aged 10-18 years old WC was measured at four different sites of trunk region, WC1; at midway between the lowest rib and the iliac crest, WC2; at the narrowest waist, WC3; at immediately above the iliac crest and WC4; at the umbilicus level. Receiver operating characteristic analysis was also performed to determine WC cutoffs to maximize the sensitivity and specificity.
