Observational study reveals combining waist circumference with body mass index improves risk detection in truck drivers, indicating combined metrics better capture cardiometabolic health.
INTRODUCTION: This study examined and compared the association between body mass index (BMI) and BMI with waist circumference (WC) on lifestyle measure and health outcomes in Canadian long-haul truck drivers (LHTDs). METHODS: Two hundred LHTDs completed a survey on diet and physical activity, and participated in objective measures of height, weight, WC, and blood pressure. RESULTS: More than half of the sample was classified as obese (57%). Body mass index risk was significantly associated with poorer health ( P < 0.05), increased systolic and diastolic blood pressure, increased body fat ( P < 0.001), and sleep apnea ( P < 001). When BMI + WC was used, additional significant associations were observed with age, years of experience, eating breakfast, and hypertension and malignancy. CONCLUSION: Body mass index + WC is a more sensitive measure in assessing cardiometabolic risk in LHTDs than using BMI alone.
