To decrease BMI in overweight and obese children, improved dietary intake and increased physical activity are key elements. Our objective was to evaluate the impact of a 1-y food and physical activity intervention on energy and macronutrient intake in overweight and obese children. A randomized open trial was conducted with 92 overweight or obese 10.4 ± 1.08-y-old children. The intervention included 14 group sessions with different themes regarding food and physical activity. Dietary intake was assessed with diet history interviews covering 14 d at baseline and 4-d food records after 1 y and was evaluated according to national dietary recommendations. The control group participated in the same measurements as the intervention group but did not take part in group sessions. After 1 y, both groups had decreased their energy intake (EI) relative to total energy expenditure, but the effect was more pronounced for the intervention group than for the control group. At 1 y follow-up, a larger proportion of children in the intervention group compared with the control group met the recommended intake of refined sugar (P = 0.019). However, the groups did not differ in the proportion children who met the recommended intake of dietary fiber. Further, SFA intake relative to total EI did not differ between the groups at 1 y follow-up. In conclusion, despite a rather comprehensive intervention, only modest effects were achieved with respect to reduced EI and improved macronutrient intake.
对于超重和肥胖儿童而言,减少体重指数的关键在于改善饮食摄入和增加体育活动。我们的目标是评估为期1年的食物和体育活动干预对超重和肥胖儿童能量及宏量营养素摄入的影响。对92名年龄为10.4±1.08岁的超重或肥胖儿童进行了一项随机开放试验。干预措施包括14次关于食物和体育活动的不同主题的小组会议。通过在基线时进行为期14天的饮食史访谈以及1年后进行4天的食物记录来评估饮食摄入情况,并根据国家饮食建议进行评估。对照组与干预组进行相同的测量,但不参加小组会议。1年后,两组相对于总能量消耗均减少了能量摄入(EI),但干预组的效果比对照组更明显。在1年随访时,与对照组相比,干预组中有更大比例的儿童达到了精制糖的推荐摄入量(P = 0.019)。然而,在达到膳食纤维推荐摄入量的儿童比例方面,两组没有差异。此外,在1年随访时,两组之间相对于总EI的饱和脂肪酸摄入量没有差异。总之,尽管进行了相当全面的干预,但在降低EI和改善宏量营养素摄入方面仅取得了适度的效果。
