本研究的目的是检查强度特定的闲暇时间体力活动（LTPA）在怀孕期间的变化的预测因素，并在芬兰孕妇在妊娠糖尿病的风险增加LTPA的感知支持和障碍。研究人群包括399名孕妇，他们参加了一项旨在预防妊娠期糖尿病的随机对照试验。LTPA的评估基于基线、26-28周和36-37周妊娠时的自我报告。通过问卷调查和孕妇卡收集有关变化预测因素、感知支持和障碍的数据。多项逻辑回归用于评估变量之间的关联。光强度LTPA的平均每周分钟数在基线时为179，在妊娠26-28周时为161，在妊娠36-37周时为179。中等强度至高强度LTPA的相应分钟数分别为187、133和99分钟。在妊娠26-28周时，轻度LTPA的最强预测因素是妊娠前符合PA建议，受过理工教育和兼职工作，而妊娠前有一个身体活跃的配偶是中度至重度LTPA的最强预测因素。鼓励妇女进行LTPA的人和/或因素最多的是配偶，孩子，其他家庭成员和天气，而疲劳，恶心，自认为的健康，工作和缺乏时间限制他们的LTPA最多。怀孕期间维持LTPA的最强预测因素是孕前LTPA、教育、兼职工作和配偶的LTPA。最常见的障碍是健康、工作和缺乏时间。
The aim of this study was to examine the predictors of change in intensity-specific leisure-time physical activity (LTPA) during pregnancy, and the perceived support and barriers of LTPA in Finnish pregnant women at increased risk of gestational diabetes. The study population consisted of 399 pregnant women who participated in a randomized controlled trial aiming to prevent gestational diabetes. Evaluation of LTPA was based on a selfreport at baseline, 26-28, and 36-37 weeks' gestation. Data on predictors of change, perceived support and barriers were collected with questionnaires and from the maternity cards. Multinomial logistic regression was used to assess associations between the variables. The average weekly minutes of light-intensity LTPA were 179 at baseline, 161 at 26-28 weeks' gestation, and 179 at 36-37 weeks' gestation. The corresponding minutes of moderate-to-vigorous-intensity LTPA were 187, 133 and 99. At 26-28 weeks' gestation, the strongest predictors for light-intensity LTPA were meeting the PA recommendations prior to pregnancy, having polytechnic education and working part-time, while having a physically active spouse prior to pregnancy was the strongest predictor for moderate-to-vigorous-intensity LTPA. The people and/or factors that encouraged women to LTPA the most were the spouse, a child, other family members and weather, whereas tiredness, nausea, perceived health, work and lack of time restricted their LTPA the most. The strongest predictors for maintaining LTPA during pregnancy were pre-pregnancy LTPA, education, working part-time and a spouse's LTPA. Most common barriers were perceived health, work and lack of time.
