目的:本研究旨在评估基于Fogg行为模型的在线和离线混合体重管理方法对妊娠总体重增加和围产期结局的影响。
方法:海南孕妇,中国最南端的省份,被招募到一项随机对照试验中,旨在开发一个怀孕体重管理的微信平台,并在Fogg行为模式的指导下对孕妇实施个体化、连续性的孕期体重管理服务。所有参与研究的孕妇均纳入完整分析集(FAS)进行分析。完成干预并提供所有结局指标的孕妇被纳入每个方案集(PPS)以进行结局评估。
结果:58名孕妇被纳入FAS分析,52名孕妇最终纳入PPS分析。两组基线比较差异无统计学意义(P>0.05)。干预组的孕期体重增长明显低于对照组(P<0.05)。在对照组中,孕期适当增重率为48.26%,干预组孕期适当增重率为93.30%,差异具有统计学意义(P<0.05)。在交付结果中,干预组剖宫产率明显低于对照组,差异均有统计学意义(P<0.05)。干预组妊娠期糖尿病和妊娠期高血压的发生率低于对照组,差异均有统计学意义(P<0.05)。干预组新生儿体重、巨大儿发生率低于对照组,差异有统计学意义(P<0.05)。
结论:本研究结合线上微信平台和基于Fogg行为模型的线下咨询的个体化连续孕期体重管理,在改善母婴结局方面显示出巨大潜力。

OBJECTIVE: This study aimed at evaluating the effects of online and offline hybrid weight management approach based on the Fogg behavior model on total gestational weight gain and perinatal outcomes.
METHODS: Pregnant women in Hainan, the southernmost province of
China, were recruited into a randomized controlled trial, which was designed to develop a WeChat platform for pregnancy weight management, and implement individualized and continuous pregnancy weight management services for pregnant women under the guidance of the Fogg behavior model. All pregnant women participating in the study were included in the full analysis set (FAS) for analysis. The pregnant women who completed the intervention and provided all outcome indicators were included in the per protocol set (PPS) for outcome evaluation.
RESULTS: Fifty-eight pregnant women were included in FAS analysis, and 52 pregnant women were finally included in PPS analysis. There was no statistically significant difference (P > 0.05) between the two groups at baseline. The gestational weight gain of the intervention group was significantly lower than that of the control group (P < 0.05). In the control group, the rate of appropriate weight gain during pregnancy was 48.26%, the rate of appropriate weight gain during pregnancy was 93.30% in the intervention group, with a statistically significant difference (P < 0.05). In the delivery outcomes, the cesarean section rate in the intervention group was significantly lower than that in the control group, and the differences were statistically significant (P < 0.05). The incidence of gestational diabetes mellitus and gestational hypertension in the intervention group was lower than those in the control group, and the differences were statistically significant (P < 0.05). The neonatal weight and incidence of macrosomia of the intervention group were lower than that of the control group, and the difference was statistically significant (P < 0.05).
CONCLUSIONS: This study combined the individualized and continuous pregnancy weight management of the online WeChat platform and offline consultation based on the Fogg behavior model, showing great potential in improving maternal and infant outcomes.
