Social Isolation and Excessive Weight Gain in Infants: A Nationwide Cohort Study of 1.8 Million Infants.
Article in Journal of paediatrics and child health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveInfant weight gain predicts childhood obesity, yet the effect of pandemic-related social isolation on first-year weight gain is unclear. We assessed its impact and implications for obesity risk.
methodsWe analysed a nationwide birth cohort of South Korean children born 2014-2021, excluding prematurity, low birth weight or neonatal intensive care admission. Anthropometrics at 9-12 months were used. Interrupted time-series regression compared pre-pandemic (January 2015-January 2020) and pandemic (February 2020-December 2021) periods, adjusting for confounders. Relative risks (RRs) were estimated using modified Poisson regression with robust standard errors. The primary outcome was accelerated weight gain, defined as a change in weight-for-age Z-score (ΔWAZ) > 1.0. The secondary outcome was rapid weight gain, ΔWAZ > 0.67, encompassing excessive (ΔWAZ > 0.67 to ≤ 1.0) and accelerated (ΔWAZ > 1.0) gain.
resultsAmong 1 809 054 infants (51.2% male), accelerated gain rose immediately after social isolation began (RR, 1.173; 95% confidence interval, CI, 1.154-1.193) and remained elevated (RR, 1.093; 95% CI, 1.063-1.125). Excessive gain likewise increased immediately (RR, 1.173; 95% CI, 1.154-1.192) and persisted (RR, 1.040; 95% CI, 1.025-1.055). Birth weight was stable (mean 3.24 kg, SD 0.36), while breastfeeding rates declined, socioeconomic levels rose and perinatal abnormalities increased. Infants born during the pandemic gained an additional 244 g (95% CI, 214-275) by 9-12 months.
conclusionsInfants born during pandemic-related social isolation gained more weight in the first year than pre-pandemic cohorts. Policies that sustain breastfeeding, promote healthy feeding and active play, support caregiver mental health and ensure routine early growth monitoring may help mitigate these risks.
