Key result
A U-shaped association exists between BMI and mortality in East Asians (lowest risk at 23-27 kg/m2), while this association was not observed in Indian and Bangladeshi subjects.
Why the study?
Does BMI affect mortality and disability in Asian populations?
Does BMI affect mortality and disability in Asian populations?
The relationship between BMI and health outcomes in Asian populations is complex, demonstrating a U-shaped mortality curve in East Asians and varying effects based on age, ethnicity, and specific health endpoints.
Supports BMI 23-27 kg/m² range for lowest mortality in East Asians; leaves open subgroup-specific targets amid heterogeneity.
the risks for death from any cause specific causes 1 million Asian subjects. 14There was a U-shaped association between BMI and of death from cancer, and from cardiovascular disease in East Asian subjects, and this shape similar to the European trend.The lowest risk of death was associated with the BMI range 23-27 kg/m 2 .In that study, they analyzed Indian and Bangladeshi subjects separately from East Asian subjects, because there is a considerable heterogeneity between these two populations, and reported that the association was not seen in the Indian and Bangladeshi subjects.While morbidity and mortality are important issues, disability in elderly people is also a big issue due to the increase in the aging population.A recent study investigated the relationship between BMI and the incidence of cause-specific disability due to dementia, stroke, and joint disease in elderly Japanese people. 15t showed that BMI 23-29 kg/m 2 did not pose a significantly high risk for any-cause disability.Thus, when you think about the effect of obesity on health, you should notice that the effects may differ depending what you see on, ie, mortality for any cause or specific cause, the risk for specific disease or disability.In addition, the age and racial characteristics of the study population should also be taken into account.

Goda et al. (2016) conducted a review in Obesity and Overweight (n=1,000,000). Body Mass Index (BMI) was evaluated on Mortality and disability. A U-shaped association exists between BMI and mortality in East Asians (lowest risk at 23-27 kg/m2), while this association was not observed in Indian and Bangladeshi subjects.
