本研究旨在探讨学龄前儿童看电视的习惯(即看电视的时间、观看的内容和观看时吃的食物)、每日食物摄入量、一般体力活动水平与其身体质量指数(BMI)的关系。方法：横断面抽样调查墨尔本学龄前儿童(n=135)。学龄前儿童的母亲完成了为期3天的电视日记；收集了关于观看时间、内容和看电视时消耗的食物的信息。母亲们还报告了孩子的身高、体重和身体活动行为。结果：学龄前儿童的平均年龄为4.5岁，其中14%的儿童超重或肥胖。平均每天看电视的时间为90.7分钟(SD 50.7)，工作日看电视与儿童BMIz呈正相关(P
Issue Addressed: The mechanisms underlying the relationship between television (TV) viewing and weight status in preschool aged children are not well understood.This study aimed to explore the relationships between preschool children's TV viewing habits (i.e. time spent viewing, content watched and foods eaten while viewing), daily food intake, general physical activity levels and their body mass index (BMI).Method: A cross-sectional sample of preschool children in Melbourne (n = 135). Mothers of preschoolers completed a 3-day TV diary; information was collected on viewing time, content and food consumed while watching TV. Mothers also reported their child's height, weight and physical activity behaviour. Associations between study and outcome variables were determined by bivariate correlations and hierarchical regression analyses.Results: Mean age of preschoolers was 4.5 years and 14% were overweight or obese. The mean daily time spent watching TV was 90.7 minutes (SD 50.7) A small, positive correlation was found between viewing TV on weekdays and child BMIz, (p
