Abstract

Background

Half of women with overweight gain excessive weight during pregnancy. Perceived self-efficacy plays a significant role in adherence to healthy behaviours, especially in turning points of life, such as a pregnancy.

Objectives

To assess the effectiveness of the Supporting lifestyle change in pregnant mothers with obesity through the wearable internet-of-things (SLIM)-intervention in terms of improving self-efficacy in eating and physical activity and preventing excessive weight gain of pregnant women with overweight. The second aim was to evaluate the fidelity of the intervention implementation.

Methods

Pregnant women with overweight (N = 54) attending maternity clinics in Southwest Finland between 2021 and 2023, were recruited using convenience sampling. The SLIM-intervention included: health technology, motivational interviewing, feedback, and goal setting. The intervention was implemented in prenatal visits in maternity clinics continuing to 12 weeks postpartum. The change in self-efficacy was measured with Weight Efficacy Life-Style Questionnaire (score 0–180) and Self-Efficacy for Physical Activity Scale (score 5–25) with repeated measures in three timepoints. Data on weight were collected from patient records.

Results

The levels of self-efficacy were high throughout the study period and there were no significant changes in self-efficacy in eating (p = 0.650) or physical activity (p = 0.936). Most of the women (N = 9/10), whose gestational weight gain was within recommendations or less, managed to lose weight during the postpartum period (p < 0.001).

Conclusions

Although the intervention was not effective in improving self-efficacy, the importance of recommended gestational weight gain on better postpartum weight management was highlighted. A long follow-up time was valuable for examination of changes over time and understanding trends, patterns, and outcomes of the study.

Registration

The trial was registered at the Clinicaltrials.gov register platform (ID NCT04826861) on March 17th, 2021.

通过可穿戴物联网（SLIM）干预支持肥胖孕产妇改变生活方式对孕妇体重管理自我效能的影响：准实验性试验。

背景：半数超重妇女在怀孕期间体重增加过多。自我效能感在坚持健康行为方面发挥着重要作用，尤其是在人生的转折点，如怀孕期间：评估通过可穿戴物联网（SLIM）干预对肥胖孕产妇生活方式改变的支持效果，以提高肥胖孕产妇在饮食和体育锻炼方面的自我效能，防止体重增加过多。第二个目的是评估干预实施的忠实性：方法：在 2021 年至 2023 年期间，在芬兰西南部产科诊所就诊的超重孕妇（N = 54）均为方便抽样调查对象。SLIM干预包括：健康技术、动机访谈、反馈和目标设定。干预措施在产科诊所的产前检查中实施，一直持续到产后 12 周。自我效能的变化通过体重效能生活方式问卷（0-180 分）和体育活动自我效能量表（5-25 分）进行测量，并在三个时间点进行重复测量。体重数据来自患者病历：在整个研究期间，患者的自我效能感水平都很高，在饮食（P= 0.650）和体育锻炼（P= 0.936）方面的自我效能感没有显著变化。大多数妇女（9/10）的妊娠体重增加在建议范围内或更少，但在产后期间体重成功下降（p < 0.001）：尽管干预措施在提高自我效能方面效果不佳，但却强调了建议的妊娠体重增加对产后更好地控制体重的重要性。较长的随访时间对于检查随时间推移而发生的变化以及了解研究的趋势、模式和结果非常有价值：该试验于 2021 年 3 月 17 日在 Clinicaltrials.gov 注册平台注册（ID NCT04826861）。
