Intergenerational Effects of Maternal Stressful Life Events Before Pregnancy on Offspring Growth: A Lifecourse Approach from a Prospective Cohort.
Article in International journal of women's health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Guided by the lifecourse perspective and the developmental origins of health and disease paradigm, this study investigated the intergenerational impact of maternal preconception stressful life events (PSLEs) on offspring growth trajectories. Methods: Data were drawn from the Early Childhood Longitudinal Study, Birth Cohort, a nationally representative prospective cohort of approximately 8,500 mother-child pairs born in 2001 and followed through kindergarten entry. Maternal exposure to PSLEs (eg, bereavement, divorce, or fertility problems) was operationalized as the primary exposure. Outcomes included BMI percentile trajectories and categorical weight status from 9 to 60 months. Mixed-effects and survival models were employed to estimate the effects of PSLEs on offspring growth, stratified by sex and race/ethnicity. These analyses accounted for baseline confounders and the potential mediating role of being born small-for-gestational-age. Results: Maternal PSLEs were significantly associated with lower BMI percentiles (b = -4.09; 95% CI: -7.03, -1.16) and a 35% reduction in the odds of being overweight or obese (AOR = 0.65; 95% CI: 0.44, 0.95) exclusively among Non-Hispanic (NH) White male infants. However, no associations were observed across all female strata and within NH Black, Hispanic, and other minority male populations. Conclusion: The findings suggest a need for future research across diverse populations to elucidate these unique intergenerational effects within lifecourse perspectives.
