Traditional obesity prevention programs are time- and cost-intensive. Mobile phone technology has been successful in changing behaviors and managing weight; however, to our knowledge, its potential in young children has yet to be examined. We assessed the effectiveness of a mobile health (mHealth) obesity prevention program on body fat, dietary habits, and physical activity in healthy Swedish children aged 4.5 y. From 2014 to 2015, 315 children were randomly assigned to an intervention or control group. Parents in the intervention group received a 6-mo mHealth program. The primary outcome was fat mass index (FMI), whereas the secondary outcomes were intakes of fruits, vegetables, candy, and sweetened beverages and time spent sedentary and in moderate-to-vigorous physical activity. Composite scores for the primary and secondary outcomes were computed. No statistically significant intervention effect was observed for FMI between the intervention and control group (mean ± SD: -0.23 ± 0.56 compared with -0.20 ± 0.49 kg/m). However, the intervention group increased their mean composite score from baseline to follow-up, whereas the control group did not (+0.36 ± 1.47 compared with -0.06 ± 1.33 units; = 0.021). This improvement was more pronounced among the children with an FMI above the median (4.11 kg/m) ( = 0.019). The odds of increasing the composite score for the 6 dietary and physical activity behaviors were 99% higher for the intervention group than the control group ( = 0.008). This mHealth obesity prevention study in preschool-aged children found no difference between the intervention and control group for FMI. However, the intervention group showed a considerably higher postintervention composite score (a secondary outcome) than the control group, especially in children with a higher FMI. Further studies targeting specific obesity classes within preschool-aged children are warranted. This trial was registered at clinicaltrials.gov as NCT02021786.
传统的肥胖预防项目耗时且成本高昂。移动电话技术已成功改变行为并管理体重；然而，据我们所知，其在幼儿中的潜力尚未得到研究。我们评估了一项移动健康（mHealth）肥胖预防项目对4.5岁健康瑞典儿童体脂、饮食习惯和身体活动的有效性。2014年至2015年，315名儿童被随机分为干预组或对照组。干预组的家长接受了为期6个月的mHealth项目。主要结局是脂肪量指数（FMI），次要结局是水果、蔬菜、糖果和含糖饮料的摄入量以及久坐时间和中度至剧烈身体活动时间。计算了主要和次要结局的综合得分。干预组和对照组之间在FMI方面未观察到统计学上的显著干预效果（均值±标准差：-0.23±0.56与-0.20±0.49kg/m相比）。然而，干预组从基线到随访的平均综合得分有所增加，而对照组则没有（+0.36±1.47与-0.06±1.33单位相比；P=0.021）。这种改善在FMI高于中位数（4.11kg/m）的儿童中更为明显（P=0.019）。干预组增加6种饮食和身体活动行为综合得分的几率比对照组高99%（P=0.008）。这项针对学龄前儿童的mHealth肥胖预防研究发现，干预组和对照组在FMI方面没有差异。然而，干预组在干预后的综合得分（次要结局）明显高于对照组，尤其是在FMI较高的儿童中。有必要针对学龄前儿童中的特定肥胖类别开展进一步研究。该试验已在clinicaltrials.gov上注册，注册号为NCT02021786。
