Despite the known useful effects of regular physical activity during the preconception period on pregnancy outcomes, sedentary lifestyle is a prevalent phenomenon in reproductive-aged women. Using social cognitive theory (SCT) as its theoretical framework, the aim of this study was to explain physical activity model in the women preparing for pregnancy in Isfahan, Iran. This cross-sectional study was conducted on 220 Iranian women undergoing preconception care. The SCT constructs were measured using a researcher-made questionnaire. The duration of physical activity with moderate/severe intensity was also measured using the long form of the International Physical Activity Questionnaire. The data were analyzed using Spearman correlation coefficient and multivariable linear regression. The theoretical model was tested using structural equation modeling. The results showed that observational learning (β =.65, <.0001) was the most important determinant of the physical activity level. The default model provided an adequate to good fit to the data (CMIN/DF = 2.10, =.097). The results of the present study emphasized the role of observational learning in forming physical activity behavior in pre-pregnancy period; therefore, the design of interventions for providing the opportunity of observational learning may improve the level of physical activity among the women preparing for pregnancy.
尽管已知在受孕前定期进行身体活动对妊娠结局有益，但在育龄妇女中，久坐不动的生活方式仍然很普遍。本研究以社会认知理论（SCT）为理论框架，旨在解释伊朗伊斯法罕准备怀孕的妇女的身体活动模式。这是一项横断面研究，共纳入 220 名正在接受孕前保健的伊朗女性。使用研究者自制的问卷测量 SCT 结构。使用国际体力活动问卷长表测量中等/剧烈强度体力活动的持续时间。使用 Spearman 相关系数和多变量线性回归分析数据。使用结构方程模型检验理论模型。结果表明，观察学习（β=.65，<.0001）是体力活动水平的最重要决定因素。默认模型对数据具有足够到良好的拟合度（CMIN/DF=2.10，=0.097）。本研究结果强调了观察学习在形成孕前体力活动行为中的作用；因此，设计提供观察学习机会的干预措施可能会提高准备怀孕的妇女的体力活动水平。
