Does the relationship between body mass index and health-related quality of life vary depending on early, middle and later adulthood?
Article in Family medicine and community 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
objectiveThis study investigated the association between body mass index (BMI) and health-related quality of life (HRQoL) in a Korean adult population using a nationwide population-based survey.
designCross-sectional study.
settingThis study analysed data from the 2021 Community Health Survey in South Korea.
participantsA total of 223 336 respondents were aged ≥19 years.
resultsUnderweight status was consistently associated with lower EuroQol HRQoL (EQ-5D) index scores across all age groups (early, middle and later adulthood), with the detrimental impact being most pronounced in men and the elderly (≥65 years). Specifically, underweight men aged 40-64 years exhibited the highest risk for problems in anxiety/depression (OR 2.48; 95% CI 1.86 to 3.30).The association between obesity and HRQoL showed different patterns depending on sex. In women, obesity was negatively associated with HRQoL across all life stages; notably, young women (19-39) with preobesity or obesity reported difficulties in all five EQ-5D dimensions. Conversely, in men aged ≥40 years, obesity was associated with better HRQoL outcomes and lower odds of anxiety/depression among those aged 40-64 years (OR 0.85; 95% CI 0.77 to 0.94) and those aged ≥65 years (OR 0.88; 95% CI 0.79 to 0.98).
conclusionsThe association between BMI and HRQoL differs according to sex and age. Policy attention regarding HRQoL may benefit from considering the maintenance of proper weight and the promotion of nutritional health, tailored to sex and age.
