BACKGROUND
Nowadays because of some necessities and demands for virtual and remote education, a new model of health approach through mobile-phones is widely used to deal with improving physical activity and its beneficial effect on pregnancy. There are a small number of studies for showing this importance and the efficacy of such methods, so this study was aimed to determine the influence of social networking through mobile phones on changing the physical activity behavior in pregnant women.
METHODS
This randomized controlled trial was conducted with parallel groups on 90 pregnant women referring to Urmia health centers in 2018-2019. The participants from various social and economic backgrounds were included. The participants were randomly assigned to a control and a treatment group. Demographic and Pregnancy Physical Activity Questionnaire (PPAQ) questionnaires were filled. In addition to routine cares, the treatment group received educational intervention through social network within 16 training sessions related to physical activity and nutrition in 8 weeks.
RESULTS
The mean weight in both control and treatment groups changed significantly during the study, but in different trends (P < 0.001, Mean Difference (MD) = 4.43). At the beginning of the study, control and treatment groups were not different in terms of daily physical activity level (P = 0.17, MD = 0.62), meanwhile, there was a statistically significant difference at the end of intervention in the level of daily physical activity (P < 0.001, MD = 0.69). Comparison of both groups, based on different categories of activity level at the end of the treatment, showed a non-significant difference in sedentary activities (P = 0.89, MD = 0.46), but the intervention led to a significant difference based on the other level of activities; light (P < 0.001, MD = 51.94), moderate (P < 0.001, MD = 46.87), and sever (P = 0.05, MD = 1.07).
CONCLUSION
Educational intervention based on social networks through mobile phones had an effective role in behavior change in physical activity during pregnancy.

背景
如今，由于虚拟远程教学的一些需求，通过手机进行健康干预的新模式已被广泛应用于提高身体活动水平及其对妊娠的有益影响。虽然有一些研究表明了这些方法的重要性和效果，但本研究旨在确定通过手机社交网络对改变孕妇身体活动行为的影响。
方法
这是一项在 2018 年至 2019 年间，于乌尔米亚医疗中心进行的、采用平行分组的随机对照试验，纳入了具有不同社会经济背景的 90 名孕妇。将参与者随机分为对照组和治疗组。填写人口统计学和妊娠体力活动问卷（PPAQ）。除常规护理外，治疗组还在 8 周内通过社交网络接受了 16 次与身体活动和营养相关的教育干预。
结果
在研究过程中，对照组和治疗组的平均体重均发生显著变化，但趋势不同（P<0.001，均数差（MD）=4.43）。在研究开始时，对照组和治疗组的日常体力活动水平没有差异（P=0.17，MD=0.62），而在干预结束时，体力活动水平有统计学意义上的显著差异（P<0.001，MD=0.69）。比较两组在治疗结束时不同活动水平的情况，在久坐活动（P=0.89，MD=0.46）方面无显著差异，但在其他活动水平方面，干预有显著差异；轻度（P<0.001，MD=51.94）、中度（P<0.001，MD=46.87）和重度（P=0.05，MD=1.07）。
结论
基于手机社交网络的教育干预在改变孕妇怀孕期间的体力活动行为方面发挥了有效作用。
