Household chaos did not explain weight-intervention effects during pregnancy
In a trial involving pregnant people with low socioeconomic status, household-chaos scores showed no statistically significant overall change, and mediation analysis did not identify an explanatory role.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Household chaos showed no statistically significant overall change from early to late pregnancy, and changes in chaos did not explain the intervention's effect on gestational weight gain. This is a finding about a proposed pathway. It does not tell us from this abstract how much the program changed weight gain itself.
The abstract does not report the intervention's weight-gain effect size or uncertainty estimates for the mediation analysis. A null mediation finding does not establish that household conditions are irrelevant to pregnancy health.
What researchers found
Household-chaos score
Participants' late-pregnancy scores compared with their own early-pregnancy scores, across both trial groups.
What the groups received
Both groups received the standard WIC program and coaching support. The intervention added emailed health information and more frequent discussions focused on eating and physical activity; usual care included general pregnancy recommendations.
Testing a proposed pathway
Researchers tested whether changes in household chaos helped account for any intervention effect on pregnancy weight gain. Participants' individual patterns varied, but the mediation analysis did not identify chaos change as an explanation.
