Association between an excessive body mass index and coronary heart disease risk factors in military personnel.
The purpose of this study was to document the extent of coronary heart disease (CHD) risk factors in military personnel (412 men, 50 women) classified as seriously overweight (body mass index [BMI] 27.0-29.9 kg/m2) or obese (BMI > or = 30 kg/m2) and to evaluate the utility of the BMI to discriminate among individuals with an adverse CHD risk profile. Mean body weight and BMI greatly exceeded Canadian norms, whereas mean heights were average. There were low but significant correlations between BMI and resting and submaximal exercise (stage A of the Canadian Aerobic Fitness Test) heart rates and blood pressures, while the correlation with predicted VO2max was negative. Except for blood glucose level (GLU) in men, there were no significant correlations between BMI and various biochemical indices. Compared to "overweight" men, the percentage of "obese" men with abnormal values for risk factors were higher, particularly for an adverse exercise blood pressure response and low predicted VO2max. In summary, the correlations between BMI and the various CHD risk factors, except for GLU and the exercise parameters, were minimal or moderate at best. It was concluded that in overweight and obese individuals, BMI does not appear to be a particularly sensitive indicator of body fat and risk factors.
