Impact of maternal education on response to lifestyle interventions to reduce gestational weight gain: individual participant data meta-analysis
Open accessAbstract
Objectives: To identify if maternal educational attainment is a prognostic factor for gestational weight gain (GWG), and to determine the differential effects of lifestyle interventions (diet based, physical activity based or mixed approach) on GWG, stratified by educational attainment. Design: Individual participant data meta-analysis using the previously established International Weight Management in Pregnancy (i-WIP) Collaborative Group database (https://iwipgroup.wixsite.com/collaboration). Preferred Reporting Items for Systematic reviews and Meta-Analysis of Individual Participant Data Statement guidelines were followed. Data sources: Major electronic databases, from inception to February 2017. Eligibility criteria: Randomised controlled trials on diet and physical activity-based interventions in pregnancy. Maternal educational attainment was required for inclusion and was categorised as higher education (≥tertiary) or lower education (≤secondary). Risk of bias: Cochrane risk of bias tool was used. Data synthesis: Principle measures of effect were OR and regression coefficient. Results: Of the 36 randomised controlled trials in the i-WIP database, 21 trials and 5183 pregnant women were included. Women with lower educational attainment had an increased risk of excessive (OR 1.182; 95% CI 1.008 to 1.385, p =0.039) and inadequate weight gain (OR 1.284; 95% CI 1.045 to 1.577, p =0.017). Among women with lower education, diet basedinterventions reduced risk of excessive weight gain (OR 0.515; 95% CI 0.339 to 0.785, p = 0.002) and inadequate weight gain (OR 0.504; 95% CI 0.288 to 0.884, p=0.017), and reduced kg/week gain (B −0.055; 95% CI −0.098 to −0.012, p=0.012). Mixed interventions reduced risk of excessive weight gain for women with lower education (OR 0.735; 95% CI 0.561 to 0.963, p=0.026). Among women with high education, diet based interventions reduced risk of excessive weight gain (OR 0.609; 95% CI 0.437 to 0.849, p=0.003), and mixed interventions reduced kg/week gain (B −0.053; 95% CI −0.069 to −0.037,p<0.001). Physical activity based interventions did not impact GWG when stratified by education. Conclusions: Pregnant women with lower education are at an increased risk of excessive and inadequate GWG. Diet based interventions seem the most appropriate choice for these women, and additional support through mixed interventions may also be beneficial.

A meta-analysis of 36 RCTs found that the success of interventions was highly dependent upon characteristics of the women recruited and whether the interventions were based upon diet, exercise or a combination of the two.

From Overweight, obesity and excessive weight gain in pregnancy as risk factors for adverse pregnancy outcomes: A narrative review (2022) · cites this paper as [130]
The Methods report an original dataset of 36 RCTs, but Results > Protocol, IPD obtained and study characteristics says this analysis included participants from 21 RCTs. Results > Results of syntheses reports differences by intervention type and educational group, but the intervention-by-education interactions were not statistically significant. The claim therefore overstates how strongly success depended on women's characteristics. (LLM, conf=0.90)
Experimental — accuracy not yet measuredPhysical activity-based interventions were generally ineffective.
“Physical activity‐based interventions were generally ineffective. Interventions appear to be more effective if delivered by clinicians rather than non‐clinical staff. 131”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
