Parental obesity and offspring cardiometabolic trajectories from childhood to adulthood.
Article in Frontiers in 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
Objectives: Parental obesity is a strong risk factor for childhood adiposity. However, evidence regarding its association with longitudinal cardiometabolic disease progression in offspring remains limited. We aimed to examine whether parental obesity is associated with adverse cardiometabolic trajectories in offspring from childhood to adulthood. Methods: We analyzed prospective data from the China Health and Nutrition Survey (1989-2015). Offspring aged ≥2 years were categorized according to parental overweight/obesity status: neither parent affected (Group 1, reference), only father affected (Group 2), only mother affected (Group 3), and both parents affected (Group 4). We used linear mixed-effects models with polynomial age terms to estimate longitudinal trajectories and annual changes in body mass index, waist circumference, and blood pressure. Cox proportional hazards models were used to assess hazard ratios for incident overweight/obesity, central obesity, and hypertension. Results: Among 4,982 offspring, those with both parents affected (group 4) had the highest baseline levels; however, annual rates of increase were not consistently higher. Male offspring in group 4 had the highest risks for incident overweight/obesity (HR = 3.72; 95% CI, 1.73-7.99) and central obesity (HR = 2.46; 95% CI, 1.31-4.62); the association with hypertension was elevated but did not reach statistical significance (HR = 1.55; 95% CI, 0.86-2.77). Female offspring in group 4 had the highest risk for incident overweight/obesity (HR = 4.60; 95% CI, 1.93-10.94). Formal interaction tests for sex × parental obesity were not significant for any outcome (all Conclusions: Parental obesity, particularly when both parents are affected, is associated with higher baseline cardiometabolic risk levels and substantially higher disease risk in offspring, though the annual rates of increase do not consistently differ across groups. These findings underscore the family unit as a critical target for early preventive strategies.
