Interventions based on adopting a healthy lifestyle have been less successful. The aim of this study was to investigate the effectiveness of healthy lifestyle interventions on weight gain in overweight pregnant women.
A cluster randomized controlled trial.
Health centres were selected by simple random sampling; then, 66 overweight pregnant women were enrolled by convenience sampling and divided into intervention and comparison groups. Intervention group received individual nutritional counselling and physical activity training. The data were collected in several stages with the demographic and obstetric questionnaire, maternal weight record, food frequency and international physical activity questionnaire.
Pregnancy weight gain-4.75(CI 95%: -4.02, -5.48) was significantly lower in the intervention group ( < .001). Comparing between groups with adjustment for baseline values indicated that there was a statistically significant difference in terms of total calorie 95.46 (CI 95%: -22.37, 213.30), carbohydrate 23.45 (CI 95%: 2.12, 44.78), protein -7.16 (CI 95%: -12.85, -1.47) and fat 8.82 (CI 95%: 2.21, 15.67) intake. Despite the higher level of physical activity in the intervention group, there was no statistically significant difference between the two groups.
Counselling interventions for healthy living during pregnancy can lead to controlling weight gain, improving dietary habits and increasing the physical activity in overweight pregnant women.
基于健康生活方式的干预措施效果并不理想。本研究旨在探讨健康生活方式干预对超重孕妇体重增加的影响。
整群随机对照试验。
通过简单随机抽样选择健康中心，然后通过便利抽样招募了 66 名超重孕妇，并将其分为干预组和对照组。干预组接受个体营养咨询和身体活动训练。通过人口统计学和产科问卷、孕妇体重记录、食物频率和国际身体活动问卷在几个阶段收集数据。
干预组的孕期体重增加量为 4.75（95%CI：-4.02，-5.48），显著低于对照组（<0.001）。对基线值进行调整后比较两组发现，在总热量摄入方面存在统计学差异，差值为 95.46（95%CI：-22.37，213.30），碳水化合物摄入差值为 23.45（95%CI：2.12，44.78），蛋白质摄入差值为-7.16（95%CI：-12.85，-1.47），脂肪摄入差值为 8.82（95%CI：2.21，15.67）。尽管干预组的身体活动水平较高，但两组之间没有统计学差异。
孕期健康生活方式的咨询干预可以控制体重增加，改善饮食习惯，增加超重孕妇的身体活动量。
