Do Changes in BMI during the COVID-19 Pandemic Persist in the Post-Pandemic Period in a Pediatric Population Attending Health Care Clinics? A Longitudinal Study.
Article in Hormone research in paediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionThe long-term effect of the COVID-19 pandemic on body weight has not been sufficiently analyzed. This study aimed to analyze changes in body mass index (BMI) during and after the COVID-19 pandemic among a large pediatric population attending health care clinics.
methodsThis retrospective longitudinal cohort study utilized electronic medical data of 106,871 children (52.1% males, median age 8.2 years at pre-pandemic assessment). Each child had at least one BMI measurement recorded pre-pandemic and two additional measurements: one during the pandemic and one post-pandemic.
resultsObesity rates increased from 12.8% pre-pandemic to 15.4% during the pandemic, slightly decreasing to 15.0% post-pandemic. BMI-standard deviation scores (SDSs) increased during the pandemic, in both sexes, across all ages and all socioeconomic position (SEP) clusters, and in children with pre-pandemic underweight or normal weight (all p < 0.001). After pandemic, BMI-SDS decreased but remained above pre-pandemic levels, particularly in younger children (aged 2-6 years) and those from low/medium SEP clusters (all p < 0.001). BMI-SDS continued to increase in children aged 6.1-16 years, those of Arab ethnicity, and those in the high SEP cluster.
conclusionsThe COVID-19 pandemic correlated with an overall increase in BMI-SDS, which decreased post-pandemic but remained above pre-pandemic levels. Effective policy interventions to prevent pediatric obesity are crucial.
