We examined the association of parental television (TV) rules and compliance with the American Academy of Pediatrics' (AAP) recommendations of <or=2 h of television per day in a primarily Hispanic sample of elementary school children (n=734) living on the U.S. side of the Texas-Mexico border. The potential modifying effects of children's home environment (parental TV watching, parent at home after school, and TV in bedroom) were also examined.
A cross-sectional analysis was performed on baseline survey data merged from two waves (2006 and 2007) of a CDC-funded TV reduction intervention with 4th grade children (mean age: 9.5 years). Logistic regression analyses were conducted to examine associations.
Children who had TV rules were 1.4 (95% CI: 1.04, 1.94) and 1.7 (95% CI: 1.22, 2.32) times more likely to meet the AAP recommendation for weekend and weekday TV watching, respectively. Parental TV watching and TV in bedroom modified the effect of TV rules on children's TV watching, with null associations found for children whose parents watch TV frequently and for children with no TV in bedroom. No interaction effect was found for children's afterschool context.
Parental TV limits is one strategy for reducing children's television watching that merits further investigation.
我们研究了父母制定的电视(TV)规则与遵守美国儿科学会(AAP)建议之间的关联,该建议规定在以西班牙裔为主的美国得克萨斯州-墨西哥边境的小学生(n=734)中,每天看电视的时间应<=2 小时。我们还研究了儿童家庭环境(父母看电视、放学后父母在家和卧室里有电视)的潜在调节作用。
对一项由疾病预防控制中心资助的、针对四年级儿童的电视减少干预措施的两波(2006 年和 2007 年)基线调查数据进行了横断面分析(平均年龄:9.5 岁)。采用逻辑回归分析来检验关联。
有电视规则的儿童在周末和工作日看电视时,分别有 1.4 倍(95%CI:1.04,1.94)和 1.7 倍(95%CI:1.22,2.32)更有可能符合 AAP 的建议。父母看电视和卧室里有电视这两个因素调节了电视规则对儿童看电视的影响,对于经常看电视的父母和卧室里没有电视的儿童,这种关联并不显著。放学后的环境对儿童没有交互作用影响。
父母制定的电视限制规则是减少儿童看电视的一种策略,值得进一步研究。
