Body Mass Index and Waist Circumference Correlates With Lifestyle and Health in Long-Haul Truck Drivers
Bibliographic record
Abstract
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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
