Background: Contemporary data comparing weight status and diabetes (DM) prevalence among U.S. East Asians and Filipinos are limited.
Methods: Among 23,050 Chinese and 28,201 Filipinos aged 45-64 years (mean age 55±6) with a 2016 outpatient visit in a U.S. integrated healthcare delivery system, body mass index (BMI) and DM prevalence (based on clinical diagnosis and pharmacotherapy) were ascertained. BMI was classified using Asian-specific thresholds: healthy or underweight (BMI <23), overweight (23-27.4) and obese (≥27.5 kg/m2). Differences were examined by subgroups and log-binomial regression was used to examine the independent association of ethnicity and DM risk.
Results: Among Chinese women (14,871) and men (8,179) and Filipino women (18,406) and men (9,795), overweight/obesity was higher in men vs. women and Filipino vs. Chinese (Figure, BMI distribution). Obesity was highest in Filipino men (50%). DM prevalence was highest in those with obesity; however, Filipinos of both sexes had higher DM prevalence across all weight categories (Figure) compared to Chinese, with a relative risk of 1.7 (CI 1.6-1.8), adjusting for age, BMI and sex.
Conclusion: Filipino adults have substantially higher BMI and independently higher risk of DM compared to Chinese adults. While limited to adults receiving healthcare, the data highlight the need for heightened DM surveillance and targeted care in high risk ethnic populations.
