Abstract [en]

Introduction: High weight retention after pregnancy is related to an increased risk of future obesity. The objective was to evaluate if an antenatal intervention, compared to standard care, could reduce postpartum weight retention (PPWR).

Material and methods: Women with body mass index >19, age ≥18 years, knowledge of Swedish, and pregnancy ≤16 weeks' gestation were randomized. Standard care was compared to a composite intervention including a personalized weight graph, education on recommended weight gain, prescription of exercise, and monitoring of weight until one year after delivery. Mean (kg) PPWR was compared between the groups and risk estimates (odds ratio) for excessive weight retention were calculated.

Results: Of 445 women randomized, 267 remained for analysis at ≤16 weeks postpartum and 168 at one year postpartum. The intervention group had a significantly lower mean PPWR at ≤16 weeks (1.81 kg (standard deviation, SD, 4.52) vs. 3.19 kg (SD 4.77), p=0.016). At one year postpartum, mean retention was still 0.7 kg lower in the intervention group (0.30 kg (SD 5.52) vs. 1.00 kg (SD 5.46)), the difference was not statistically significant (p=0.414). Gestational weight gain above Institute of Medicine recommendations was a significant risk factor for excessive weight retention (>5 kg) one year after delivery (OR 2.44; 95% CI; 1.08-5.52, p=0.029).

Conclusions: A composite lifestyle intervention during pregnancy reduced short-term weight retention, but the effect of the intervention did not remain at one year postpartum. A gestational weight gain above Institute of Medicine recommendations increases the risk of excessive long-term weight retention.

Abstract [en]

Background: Excessive gestational weight gain (GWG) is common in developed countries and is associated with an increased risk of maternal and offspring morbidity. Evidence regarding efficacy and safety of antenatal lifestyle intervention is limited in terms of both systematic reviews and original trials. This thesis is based on the need to further explore this research area. Objectives: To assess and grade current evidence and evaluate short and long-term effects of an antenatal lifestyle intervention on women and their offspring Materials: Controlled trials of intervention publishedbefore August 2009 were systematically searched and reviewed. A randomized controlled trial (RCT) including 445 healthy women aged >18 years with a body mass index (BMI) ≥19 and ≤16 weeks pregnant and their offspring was performed during 2007-2015 in Örebro Region, Sweden. Methods: The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was used for review. Our RCT (called the VIGA trial) compared standard care with a composite intervention consisting of education, application of a personalized weight graph, prescription of exercise and more frequent monitoring of weight. Standardized measures of weight and height in offspring waere analysed based on World Health Organization (WHO) Child Growth Standards. Results: Quality of evidence across the studies published pre-August 2009 was concluded to be very low. Our intervention significantly reduced mean GWG (kg) but the proportion of women with excessive GWG, according to recommendations, was not significantly reduced. Short- term postpartum weight retention (PPWR) was significantly lower after the intervention but no significant difference remained 1 year after delivery. Offspring mean BMI z-scores or proportion of obesity did not differ between study groups at either birth or age 5. Conclusions: The antenatal lifestyle intervention reduced mean GWG and short-term PPWR but no long-term effects on maternal weight retention or offspring obesity were seen. Alternative modes and timing of intervention should be considered in future research. Reducing the prevalence of pre-conception obesity must still be considered the primary means to improve maternal and fetal outcome.
