Recent US work identifies “metabolically healthy overweight” and “metabolically at risk normal weight” individuals. Less is known for modernizing countries with recent increased obesity. Fasting blood samples, anthropometry and blood pressure from 8,233 adults aged 18–98 in the 2009 nationwide China Health and Nutrition Survey, were used to determine prevalence of overweight (Asian cut point, BMI≥23 kg/m2) and five risk factors [pre-diabetes/diabetes (HbA1c≥5.7%) inflammation (hsCRP ≥3 mg/L), pre-hypertension/hypertension (SBP/DBP≥130/85 mmHg), high triglycerides (≥150 mg/dL), low high-density lipoprotein cholesterol (70 years: 73%). Abdominal obesity was highly predictive of metabolic risk, irrespective of overweight (e.g., “metabolically at risk overweight” relative to “metabolically healthy normal weight” [men: Relative Risk Ratio (RRR) =39.06; 95% Confidence Interval (CI): 23.47, 65.00; women: RRR=22.26; 95% CI: 17.49, 28.33]). To conclude, a large proportion of Chinese adults have metabolic abnormalities. High hypertension risk with age, irrespective of obesity underlies the low prevalence of metabolically healthy overweight. Screening for cardiometabolic-related outcomes dependent upon overweight will likely miss a large portion of the Chinese at-risk population
