Objective: To assess the clinical predictability of waist-to-hip ratio (WHR) among female civil servants who had experienced risk factors of cardiovascular disease.
Methods: Data was gathered from 4153 female civil servants aged 21-91 y working at universities who were enrolled in health screening centre at the Second Hospital Attached to Hebei Medical University, in 2006. WHR quartiles were determined., as: < 0.80, 0.80- < 0.84, 0.84- < 0.90 and > or = 0.90. Subjects were placed into high-risk categories for cardiovascular disease on the basis of national health reference on range norms of protocol including hypertension, diabetes mellitus and dyslipidemia.
Results: Participants had an increased likelihood of hypertension (systolic blood pressure), dyslipidemia (elevated triacylglycerol and descending HDL-C) and diabetes mellitus at WHR > or = 0.84. All aforementioned variables had a significant odds ratio at WHR > or = 0.84. This trend was further persisted after adjustment had been made on smoking, age, and BMI. Descended HDL-C was observed at the 0.80 < or = WHR < 0.84 when compared with WHR < 0.80.
Conclusion: These data indicated an upward shift in the critical threshold for WHR to > or = 0.84. Above which point, there was an elevation of risk factors on cardiovascular diseases among all the female civil servants. The trend persisted regardless of smoking, BMI < or > or = 28 and at what age group, among the civil servants population.
