Metabolic Health Has Greater Impact on Diabetes than Simple OverweightObesity in Mexican Americans

الملخص EN

Purpose.

To compare the risk for diabetes in each of 4 categories of metabolic health and BMI.

Methods.

Participants were drawn from the Cameron County Hispanic Cohort, a randomly selected Mexican American cohort in Texas on the US-Mexico border.

Subjects were divided into 4 phenotypes according to metabolic health and BMI: metabolically healthy normal weight, metabolically healthy overweight/obese, metabolically unhealthy normal weight, and metabolically unhealthy overweight/obese.

Metabolic health was defined as having less than 2 metabolic abnormalities.

Overweight/obese status was assessed by BMI higher than 25 kg/m2.

Diabetes was defined by the 2010 ADA definition or by being on a diabetic medication.

Results.

The odds ratio for diabetes risk was 2.25 in the metabolically healthy overweight/obese phenotype (95% CI 1.34, 3.79), 3.78 (1.57, 9.09) in the metabolically unhealthy normal weight phenotype, and 5.39 (3.16, 9.20) in metabolically unhealthy overweight/obese phenotype after adjusting for confounding factors compared with the metabolically healthy normal weight phenotype.

Conclusions.

Metabolic health had a greater effect on the increased risk for diabetes than overweight/obesity.

Greater focus on metabolic health might be a more effective target for prevention and control of diabetes than emphasis on weight loss alone.
