Clinical obesity phenotypes among older adults: prevalence, determinants, and morbidity burden from the Longitudinal Ageing Study in India
Authors' conclusion
A substantial proportion of older adults in India had preclinical or clinical obesity, particularly women, urban residents, socioeconomically advantaged groups, and socially isolated individuals.
Study context
- Population
- Adults aged ≥45 years, Longitudinal Ageing Study in India (LASI, Wave 1); classified by 2025 Lancet consensus framework using Asian-specific BMI and waist circumference thresholds with physician-diagnosed conditionsLASI Wave 1
- Participants
- 60,640 adults
- Exposure
- Without obesity vs Preclinical obesity vs Clinical obesity
- Outcome
- Prevalence of preclinical and clinical obesity
Methodological detailsnational scale, Asian-specific BMI and waist circumference thresholds, multivariable regression
- National scale
- Asian-specific BMI and waist circumference thresholds
- Multivariable regression
Main finding
As reported in the abstract
Prevalence of obesity phenotypes
- Preclinical or clinical obesity
- 37.53%
Observational data: associations, not effects.
Further findings
Determinants of higher odds of increasing obesity category
- Women
- AOR = 1.97
- Urban residents
- AOR = 1.88
- Richest MPCE quintile
- AOR = 1.91
- Socially isolated
- AOR = 1.44
- Aged ≥70 years (lower odds)
- AOR = 0.80
- Fully adjusted model
Morbidity burden
- Preclinical or clinical obesity vs without obesity: higher prevalence of hypertension, diabetes, chronic heart disease, chronic bone or joint disease, high cholesterol and multimorbidity
