Metabolic Syndrome in Asian Americans
- In spite of the lower body mass index (BMI) values and lower prevalence of overweight/obesity than whites, Asian Americans have higher rates of metabolic syndrome (MS) over the range of BMI. For A given BMI of 25-30 the prevalence of metabolic syndrome among Asian Americans is double that of whites in men (43% vs 22%) and women (30% vs 12%). 1
- Asian men and women with a BMI of 20 has a prevalence of MS comparable to whites with a BMI of 25 kg/m2.1 Comparison of MS features among various Asian Americans is given in Table 110 A.1
Table 110 A-Comparison of MS features among various Asian Indians1
|Overweight BMI 25-30 %||49||43||53||50||42||74||37||37|
|Obesity BMI >30%||26||12||17||7||14||24||8||6|
|Overweight + Obesity (%)||75||55||70||57||56||98||45||43|
|TG >150 %||24||35||39||30||36||41||30||34|
|BS >100 or diabetes %||19||24||26||21||25||35||20||20|
|BP > >135/85 %||69||54||52||50||65||74||53||46|
- The prevalence of obesity (BMI 25–30) among Asians was lower than for whites, with the exceptions of Asian Indians and Filipinos.
- The proportion of obese was about half for all Asian groups compared to whites with the exception of Filipinos using standard definition of obesity (BMI >30). Yet, diabetes, prediabetes, low HDL, and hypertriglyceridemia were all more common among Asians than whites.1 This data supports the lower BMI ranges by the Asia Pacific criteria for redefining overweight (BMI 23-25) and obesity (BMI>25) in Asian populations.1, 2See Metabolic Syndrome Criteria.
