Abstract
BACKGROUND: Excessive television (TV) viewing in preschool children has been linked to negative outcomes during childhood, including childhood obesity. In a sample of low-income families, this study examined associations between intrafamilial factors and preschool children's TV-viewing time and the moderating effect of social support from nonfamily members on this association. METHODS: In 2010, 129 mothers/female guardians of 2- to 5-year-old children enrolled at five Head Start centers in Rensselaer County, New York, completed a self-report survey. The survey assessed child TV-viewing time (including TV, DVDs, and videos) and intrafamilial risk factors, including maternal perceived stress, depressive symptoms, TV viewing, leisure-time physical activity (inactivity), and family functioning. Social support from nonfamily members (nonfamily social support) was also measured and examined as an effect modifier. RESULTS: Children watched TV an average of 160 minutes per day. Moderate depressive symptoms (Personal Health Questionnaire depression scale scores ≥10), higher perceived stress, poorer family functioning, and higher maternal TV-viewing were significantly and independently associated with greater minutes of child TV viewing, controlling for covariates. In all instances, nonfamily social support moderated these associations, such that negative experiences within the family environment were linked with higher child TV-viewing time under conditions of low nonfamily social support, but not high nonfamily support. CONCLUSIONS: Social support from nonfamily members may buffer potentially negative effects of intrafamilial factors on preschool children's TV-viewing time.
