The aims of the this prospective study were to analyse physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women's perceived barriers to leisure PA, using a socioecological framework. A sample of 133 pregnant women in two stages--at 10-12 weeks' gestation (T1) and 20-22 weeks' gestation (T2)--were evaluated. PA was assessed by accelerometry during the T1 and T2 evaluation stages. Socio-demographic characteristics, lifestyle factors and barriers to leisure PA were assessed via questionnaire. A large proportion of women (ranging from 32% to 96%) did not reach the levels of PA recommended by the guidelines. There were no significant differences between T1 and T2 with regard to compliance with PA recommendations. A decrease in PA levels from T1 to T2 was noted for all recommendations. No associations were found between participants' characteristics and adherence to the recommendations in T1 and T2. No significant differences were found in barriers to leisure PA between T1 and T2. The most commonly reported barriers to leisure PA were intrapersonal, not health related. Our results indicate that there were no differences between trimesters regarding compliance of PA recommendations, and perceived barriers were similar in both trimesters.
这项前瞻性研究的目的是，利用社会生态框架，分析孕早期和孕中期的身体活动（PA）参与情况，参考已发布的关于PA的不同指南，记录与遵循这些指南相关的个体特征，并调查孕妇休闲PA的感知障碍。对133名处于两个阶段的孕妇进行了评估，即妊娠10 - 12周（T1）和妊娠20 - 22周（T2）。在T1和T2评估阶段通过加速度计评估PA。通过问卷调查评估社会人口统计学特征、生活方式因素和休闲PA的障碍。很大一部分女性（32%至96%）未达到指南建议的PA水平。在遵循PA建议方面，T1和T2之间没有显著差异。所有建议的PA水平从T1到T2均有所下降。在T1和T2中，未发现参与者特征与遵循建议之间存在关联。T1和T2在休闲PA障碍方面未发现显著差异。最常报告的休闲PA障碍是个人内在的，与健康无关。我们的结果表明，在遵循PA建议方面，孕期各阶段之间没有差异，且两个孕期的感知障碍相似。
