OBJECTIVE: Sedentary behavior such as television viewing may be an independent risk factor for @entity301 . However, few studies have assessed the impact of television viewing time on @entity729 and it remains unclear how body fat contributes to this relationship. The aim of this study is to evaluate the association between television viewing time and subclinical @entity731 and whether effects on visceral or subcutaneous fat may mediate any associations observed. METHODS: This was a cross-sectional study of 398 Chinese @entity1 (192 @entity1 and 206 @entity1 ) from Singapore prospective study. @entity1 were free from known @entity65 and underwent interview, health screening, computed tomography scans of coronary arteries and abdomen. Spearman's correlation was used to test the correlation between television viewing time, physical activity, body composition and abdominal fat distribution. The association between television viewing time and subclinical @entity731 was assessed by multiple logistic regression analysis. RESULTS: In @entity1 , television viewing time was significantly correlated with higher body fat mass index, percent body fat, subcutaneous and visceral fat. These associations were in the same direction, but weaker and not statistically significant in @entity1 . Television viewing time (hours/day) was associated with subclinical @entity731 in @entity1 (odds ratio: 1.41, 95% CI: 1.03-1.93) but no significant association was observed in @entity1 (odds ratio: 0.88, 95% CI: 0.59-1.31) after adjusting for potential socio-demographic and lifestyle confounders. Further adjustments for biological factors did not affect these associations. CONCLUSIONS: Television viewing time was associated with greater adiposity and higher subcutaneous and visceral fat in @entity1 . TV viewing time was also associated with subclinical @entity731 in @entity1 and the potential mechanisms underlying this association require further investigation.
