Waist circumference and the risk of hypertension and prediabetes among Filipino women.
OBJECTIVE
To examine waist circumference as a risk factor for having hypertension only, impaired fasting glucose only, or both hypertension and impaired fasting glucose, and assess whether the associations vary according to overweight status. Furthermore, optimal cut-offs for waist circumference in overweight women and non-overweight women were explored.


METHODS
Data from 1,871 women aged 35-68 years in the 2005 Cebu Longitudinal Health and Nutrition Survey were used. Multinomial logistic regressions were used to model how waist circumference influenced the likelihood of having the three illness categories compared to having neither condition. Waist circumference cut-offs were explored using receiver operating characteristic analysis.


RESULTS
Adjusted for age and other confounders, each cm increase in waist circumference increased the odds of hypertension by 5 % for non-overweight women and 3 % for overweight women; impaired fasting glucose by 9 and 3 % for non-overweight and overweight women, respectively; and hypertension and impaired fasting glucose by 17 % among non-overweight versus 9 % for overweight women. Waist circumference cut-offs for non-overweight women were lower than overweight women.


CONCLUSIONS
Waist circumference was significantly associated with impaired fasting glucose and both hypertension and impaired fasting glucose, and the associations vary by overweight status.
