There is some evidence from studies in adults and limited evidence from studies in children that eating later in the day may increase the risk of overweight and obesity. In this cross-sectional study, we investigated associations between evening meal timing in children and their weight status and energy intake. Dietary data obtained from the UK's National Diet and Nutrition Survey Rolling Programme (2008-2012) for 768 children aged 4-10 years and 852 children aged 11-18 years were analysed. We tested for an association between evening meal timing (consuming the evening meal before or after 20.00 hours) and risk of overweight and/or obesity, adjusting for relevant confounding variables. We also explored whether evening meal timing was associated with overall nutrient intake. We found no association between evening meal timing and risk of obesity or risk of overweight and obesity combined in either the 4-10 years age group (obesity: OR 1·43; 95 % CI 0·49, 4·13; obesity and overweight combined: OR 1·33; 95 % CI 0·53, 3·33) or the 11-18 years age group (obesity: OR 0·50; 95 % CI 0·24, 1·02; obesity and overweight combined: OR 0·83; 95 % CI 0·50, 1·38), split by sex or as combined. No significant associations were found between evening meal timing and energy intake, and no clear patterns in variation of nutrient intakes with evening meal times were identified. In conclusion, we found no evidence that, for children aged 4-18 years in the UK, eating the evening meal after 20.00 hours was associated with excess weight or increased energy intake.
在成人研究中有一些证据，而儿童研究中的证据有限，表明在一天中较晚进食可能会增加超重和肥胖的风险。在这项横断面研究中，我们调查了儿童晚餐时间与其体重状况和能量摄入之间的关联。分析了从英国国家饮食与营养调查滚动计划（2008 - 2012年）中获取的768名4至10岁儿童和852名11至18岁儿童的饮食数据。我们测试了晚餐时间（在20:00之前或之后进食晚餐）与超重和/或肥胖风险之间的关联，并对相关混杂变量进行了调整。我们还探讨了晚餐时间是否与总体营养摄入有关。我们发现，在4至10岁年龄组（肥胖：比值比1.43；95%置信区间0.49，4.13；肥胖与超重合并：比值比1.33；95%置信区间0.53，3.33）或11至18岁年龄组（肥胖：比值比0.50；95%置信区间0.24，1.02；肥胖与超重合并：比值比0.83；95%置信区间0.50，1.38）中，无论按性别划分还是合并计算，晚餐时间与肥胖风险或超重和肥胖合并风险之间均无关联。晚餐时间与能量摄入之间未发现显著关联，也未发现营养摄入量随晚餐时间变化的明显模式。总之，我们没有发现证据表明，对于英国4至18岁的儿童，20:00之后吃晚餐与体重超标或能量摄入增加有关。
