title: High Intake of Energy and Fat in Southwest Chinese Women with PCOS: A Population-Based Case-Control Study.
abstract: BACKGROUND
  Polycystic ovary syndrome (PCOS) is a common reproductive endocrinological disease with heterogeneous phenotype. Obesity contributes to the increased prevalence and severity of PCOS. Whether the intakes of major nutrients are higher in Chinese PCOS patients is still unknown.
  
  
  OBJECTIVE
  To study the intakes of total energy, protein, fat and carbohydrate in Southwest Chinese PCOS patients.
  
  
  METHODS
  1854 women were included in the cross-sectional study. A population-based case-control study was conducted. The dietary habits and nutrients intake status of 169 PCOS patients and 338 age-matched controls were investigated by the method of semi-quantitative food frequency questionnaire.
  
  
  RESULTS
  The actual intake of total energy (P = 0.01) and fat (P = 0.01) were higher, but carbohydrate was lower (P = 0.01) in PCOS patients as compared with the controls. The energy percentage supplied by protein (12.33% ± 2.27% vs. 19.26% ± 5.91%, P<0.001) and carbohydrate (48.72% ± 6.41% vs. 68.31% ± 8.37%, P<0.001) were lower in Southwest Chinese PCOS patients than those of control, however, the energy percentage supplied by fat was higher (38.95% ± 5.71% vs. 12.42% ± 5.13%, P<0.001) in PCOS.
  
  
  CONCLUSIONS
  Limit the intake of total energy and fat shall be recommended to the Southwest Chinese PCOS patients. Women with PCOS in Southwest China shall consult with the nutritionist for improving the dietary structure.
