Physical activity in infancy is associated with body composition at age three.
Trial report in BMC public 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
backgroundThe prevalence of obesity in the pediatric population is increasing, driven by a multifactorial etiology that includes genetic predisposition as well as both prenatal and postnatal influences. We aimed to explore associations between child physical activity (PA) at ages one and three years and body composition at age three. Furthermore, we investigated associations between maternal PA during pregnancy and child body composition at age three.
methodsMother-child pairs (n = 68) from a pregnancy PA intervention study were included. Children's PA was assessed at one- and three-year follow-ups using 7-day accelerometry and categorized into 24-hour PA and daytime PA (6 a.m. - 8 p.m.). Child body composition was measured by Dual-energy X-ray absorptiometry and expressed as fat-free mass (FFM) and body fat percentage (BF%). Maternal moderate-to-vigorous intensity PA (MVPA) was measured using a commercial activity tracker. Associations between maternal and child PA and child body composition were examined using linear regression. Variables used for model adjustment included maternal pre-pregnancy body mass index, gestational weight gain, maternal educational level at baseline, parity, maternal age at baseline, child walking status at age one, child sex, and child age at the three-year follow-up.
resultsWe found a positive association between daytime PA at age one and child FFM at age three. Daytime PA at age three was positively associated with FFM, and 24-hour PA at age three was negatively associated with BF% and positively associated with FFM. A 10% increase in 24-hour PA was associated with approximately 400 g higher FFM. Maternal MVPA during pregnancy showed no association with child body composition at age three.
conclusionMore daytime PA at ages one and three was associated with higher FFM at age three in children. These findings highlight the importance of research focusing on early PA habits to support healthy body composition in young children.
