title: Person-related determinants of TV viewing and computer time in a cohort of young Dutch adults: Who sits the most?
abstract: We aimed to assess the associations of person-related factors with leisure time television (TV) viewing and computer time among young adults. We analyzed self-reported TV viewing (h/week) and leisure computer time (h/week) from 475 Dutch young adults (47% male) who had participated in the Amsterdam Growth and Health Longitudinal Study at the age of 32 and 36 years. Sociodemographic factors (i.e., marital and employment status), physical factors (i.e., skin folds, aerobic fitness, neuromotor fitness, back problems), psychological factors (i.e., problem- and emotion-focused coping, personality), lifestyle (i.e., alcohol consumption, smoking, energy intake, physical activity), and self-rated health (i.e., general health status, mild health complaints) were assessed. Univariable and multivariable generalized estimating equations were performed. Male gender, higher sum of skin folds, lower values of aerobic fitness, higher rigidity, higher self-sufficiency/recalcitrance, and smoking were positively associated with TV time. Male gender, higher sum of skin folds, higher scores on self-esteem, low energy intake, and a not so good general health status were significantly associated with higher computer time. Determinants of TV viewing and computer time were not identical, suggesting that both behaviors (a) have different at-risk populations and (b) should be targeted differently.
