To examine the extent to which television (TV) and video viewing is associated with consumption of fast food by preschool-age children.
In a cross-sectional study of 240 parents of children ages 2.0 to 5.9 years, parents reported the number of hours their child watched TV/videos on an average weekday and weekend day in the past month; a daily, weighted average of TV/video viewing was then calculated. The main outcome was parents' report of their children's fast food intake, using the question, "How many times a week does your child eat at fast food restaurants such as McDonald's, Burger King, or Kentucky Fried Chicken?" dichotomized to (never/<1 vs. > or =1 time/wk). The association of TV/video viewing with fast food intake was evaluated by multiple logistic regression before and after adjusting for several potential confounders.
Twenty-two percent of parents reported that their child ate at fast food restaurants at least once per week. After adjusting for parents' age, race/ethnicity, and household income as well as child's age and sex, for each 1-hour increase of TV/video watched per day, the odds ratio (OR) for consuming fast food > or =1 time per week was 1.60 (95% confidence interval, 1.03 to 2.49). After further adjustment for socio-environmental factors that might serve as proxies for the availability of healthy food options, such as parental time constraints and the availability and high cost of fresh fruits and vegetables in their neighborhoods, the OR for consuming fast food > or =1 time per week was minimally attenuated (OR, 1.55; 95% confidence interval, 1.04 to 2.31).
TV/video viewing was correlated with fast food consumption among preschool children in this study. Our findings raise the possibility that greater exposure to TV and videos may influence preschool children's consumption of unhealthful foods.
探讨学龄前儿童观看电视及视频与食用快餐之间的关联程度。
在一项针对240名2.0至5.9岁儿童家长的横断面研究中,家长报告其孩子在过去一个月中平日和周末平均每天看电视/视频的时长;随后计算出每天看电视/视频的加权平均时长。主要结果是家长报告孩子的快餐摄入量,问题为:“您的孩子每周在麦当劳、汉堡王或肯德基等快餐店就餐几次?”将答案分为(从不/<1次与≥1次/周)两类。在调整了几个潜在混杂因素前后,通过多元逻辑回归评估看电视/视频与快餐摄入量之间的关联。
22%的家长报告其孩子每周至少在快餐店就餐一次。在调整了家长的年龄、种族/民族、家庭收入以及孩子的年龄和性别后,每天看电视/视频每增加1小时,每周食用快餐≥1次的优势比(OR)为1.60(95%置信区间为1.03至2.49)。在进一步调整可能作为健康食品选择可及性替代指标的社会环境因素后,如家长的时间限制以及其所在社区新鲜水果和蔬菜的可及性及高成本,每周食用快餐≥1次的OR略有下降(OR为1.55;95%置信区间为1.04至2.31)。
在本研究中,观看电视/视频与学龄前儿童食用快餐相关。我们的研究结果表明,更多地接触电视和视频可能会影响学龄前儿童对不健康食品的消费。
