Waist to hip ratio (WHR) was measured in 487 middle-aged women participating in the Healthy Women Study. Upper body fat distribution was found to be associated with numerous behaviors that affect cardiovascular risk, including smoking, low exercise levels, weight gain during adulthood, and higher caloric intake. Moreover, WHR was also associated with higher levels of anger, anxiety, and depression and lower levels of perceived social support. Women with upper body fat obesity had higher systolic blood pressure, total cholesterol, low density lipoprotein cholesterol, triglycerides, and apolipoprotein B and lower levels of high density lipoprotein (HDL) and the HDL subfractions 2 and 3. These associations remained significant after adjusting for body mass index. Among 108 women who had repeat measurements of WHR, changes in WHR over a 3-year period were significantly correlated with changes in activity and with decreases in HDL,. Thus, WHR appears to be an integral component of the cardiovascular risk profile. WHR is related to those behaviors and psychosocial attributes that influence cardiovascular risk. (Arteriosclerosis and Thrombosis 1991;ll:1250-1257) R ecent studies suggest that the distribution of body fat may be a stronger predictor of coronary heart disease (CHD) than the total amount of body fat.
"4 For example, in the Paris Prospective study, men who had an upper body fat distribution were at increased risk for CHD, independent of body mass index (BMI).1 Similarly, in a prospective study conducted in Sweden 2 -3 the waist to hip ratio (WHR) was found to be positively associated with the incidence of myocardial infarction, stroke, and death from all causes in both men and women, after adjusting for BMI.The effect of upper body fat distribution on atherosclerotic disease may be mediated by the effect on cardiovascular risk factors. WHR has been associated with increased blood pressure, hypothesized that the same may be true for humans and that those individuals who experience a great deal of stress or who have difficulty coping with stress may experience higher cortisol levels and consequently may deposit more body fat in the abdominal area. The purpose of the present article is to examine the behavioral and psychosocial correlates of WHR in a population-based sample of middle-aged women who were participating in the Healthy Women Study. In addition, we assessed the relation between WHR and cardiovascular risk factors in these women. Moreover, 108 of these women also had measures of WHR completed 3 years previously. Consequently, we could determine the relation between changes in behavior and changes in WHR and the association
