Mealtime television use has been cross-sectionally associated with suboptimal diets in children. This study aimed to assess the two-year prospective association between baseline mealtime television use and subsequent diets in young children, and identify socioeconomic differences.
Parents reported their child's television use at meals, and fruit, vegetable, and discretionary food intakes. Multivariable linear and logistic regression analyses assessed the association between baseline mealtime television use and follow-up diet outcomes. Differences were assessed by socioeconomic position.
Participants were 352 Australian parents of children aged six months to six years. Daily mealtime television use (average frequency/day) was associated with higher daily frequency of discretionary food intakes (β 0.2, 95% confidence interval (CI) 0.07-0.67) at the 2-year follow-up. Individually, television use during breakfast and dinner (1-2 days/week compared to never) predicted higher daily intake frequency of discretionary food, β 0.36 (95% CI 0.12-0.60) and β 0.19 (95% CI 0.00-0.39), respectively. Similarly, 3-7 days/week of television use during breakfast and lunch predicted higher frequency of discretionary food intake, β 0.18 (95% CI 0.02-0.37) and β 0.31 (95% CI 0.07-0.55), respectively. Associations were not socioeconomically patterned.
Investigating mealtime television use motivators across the socioeconomic spectrum could inform interventions targeting the high consumption of discretionary foods in children.
用餐时看电视与儿童饮食不佳有关。本研究旨在评估幼儿基线期用餐时看电视与后续饮食之间的两年前瞻性关联，并识别社会经济差异。
父母报告了孩子在用餐时看电视以及水果、蔬菜和可自由支配食物的摄入量。多变量线性和逻辑回归分析评估了基线期用餐时看电视与随访饮食结果之间的关联。按社会经济地位评估差异。
参与者为 352 名澳大利亚 6 个月至 6 岁儿童的父母。每日用餐时看电视（平均频率/天）与 2 年随访时可自由支配食物摄入量的每日频率增加相关（β0.2，95%置信区间 0.07-0.67）。单独来看，早餐和晚餐时每天看电视（1-2 天/周，而非从不）预测可自由支配食物的每日摄入量更高，β0.36（95%置信区间 0.12-0.60）和β0.19（95%置信区间 0.00-0.39）。同样，早餐和午餐时每天看电视 3-7 天也预测了可自由支配食物摄入量的更高频率，β0.18（95%置信区间 0.02-0.37）和β0.31（95%置信区间 0.07-0.55）。这些关联没有表现出社会经济模式。
在整个社会经济范围内研究用餐时看电视的动机，可以为针对儿童高消费可自由支配食物的干预措施提供信息。
