To identify the intention of Chinese pregnant women to undertake physical activity (PA) using the theory of planned behaviour.
A cross-sectional survey.
From April - October 2017, a cross-sectional questionnaire was completed by 746 pregnant women from the Health Birth Cohort in Wuhan, China. The theory of planned behaviour variables as well as sociodemographic characteristics was recorded, and the Pregnancy PA Questionnaire was together used to assess their PA during pregnancy.
Only 11.3% of the women met the international guideline. The intention to undertake PA was found it to be positive in 63.9% of pregnant women. Structural equation modelling analysis revealed that behavioural attitudes, subjective norms, and perceived behavioural control (PBC) influenced PA by directly influencing the behaviour intention. Both behavioural attitude and subjective norms influenced PA by indirectly affecting the behaviour. Overall, the model described 60% variance of the behavioural intention to undertake PA during pregnancy.
PBC was confirmed to be a prominent factor in determining behavioural intention to undertake PA during pregnancy. Pregnant women should be helped and appropriately guided by health providers to overcome barriers to PA.
This study investigates the effect of perceived behavioural control (PBC) on the intention to undertake physical activity (PA). The findings suggest that nurses' and midwives' attention should be focused on how to promote the improvement of perceived behavioural control ability of pregnant women to improve pregnant women's PA intention. The attitude of pregnant women on taking up PA and their ability to control behaviours can be improved with support from family or healthcare providers.
运用计划行为理论，确定中国孕妇进行身体活动（PA）的意向。
横断面调查。
2017 年 4 月至 10 月，采用横断面问卷调查法，对中国武汉健康生育队列中的 746 名孕妇进行调查。记录了计划行为理论变量以及社会人口统计学特征，并使用妊娠 PA 问卷评估其妊娠期间的 PA。
只有 11.3%的女性符合国际指南。63.9%的孕妇表现出积极的 PA 意向。结构方程模型分析显示，行为态度、主观规范和感知行为控制（PBC）通过直接影响行为意向来影响 PA。行为态度和主观规范都通过间接影响行为来影响 PA。总体而言，该模型描述了 60%的孕妇在怀孕期间进行 PA 的行为意向的变异性。
PBC 被证实是决定孕妇进行 PA 的行为意向的重要因素。卫生保健提供者应帮助和适当指导孕妇，以克服 PA 的障碍。
本研究调查了感知行为控制（PBC）对进行身体活动（PA）的意向的影响。研究结果表明，护士和助产士应关注如何促进提高孕妇感知行为控制能力，以提高孕妇的 PA 意向。通过家庭或医疗保健提供者的支持，可以提高孕妇对 PA 的态度和控制行为的能力。
