Background:
This study was designed to establish appropriate body mass index (BMI) level for PCOS women and to compare metabolic abnormalities between PCOS women and control women in Southern China.
Methods:
This clinical cross-sectional study included 999 PCOS patients (857 adults and 142 adolescents) and 922 age-matched controls (742 adults and 180 adolescents).
Results:
The proportion of PCOS patients with a BMI above 23 kg/m(2) was 34.63%. Serum insulin, triglycerides, waist and waist/hip (W/H) measurements were all correlated positively with BMI in PCOS women. Prevalence of metabolic syndrome in Chinese PCOS patients was 18.9%. Receiver-operating characteristic analysis suggested that at the point of BMI > or =23 kg/m(2), the diagnostic power to detect metabolic disorders was at its best.
Conclusions:
PCOS patients with a BMI of 23 kg/m(2) or beyond may have a higher risk of metabolic disorders. Using an appropriate BMI level may help to improve attention to metabolic disorders among PCOS patients in Southern China.
