Prevalence of abdominal obesity and associated lifestyle factors in bus drivers in a city in Southern Brazil
Bibliographic record
Abstract
BACKGROUND: Bus drivers are exposed to unique working conditions. The behavioral and health trends of these workers should be investigated. OBJECTIVE: To estimate the prevalence of abdominal obesity and associated lifestyle factors in bus drivers in a city in Southern Brazil. METHODS: A cross-sectional study with 103 bus drivers with mean age of 41 years (±8.5) was conducted. Abdominal obesity was measured through waist circumference using anthropometric tape. To evaluate the different lifestyle domains, the Brazilian version of the Canadian Fantastic Lifestyle questionnaire was used. To check the association between abdominal obesity and lifestyle, binary logistic regression was used, with odds ratio (OR) estimates and 95% confidence intervals (95% CI). RESULTS: It was verified that 26.3% of drivers had abdominal obesity. In addition, bus drivers who had inadequate lifestyle in the "Nutrition" and "Type of behavior" domains were, respectively, 3.6 (95% CI: 1.3-9.5, p = 0.01) and 2.6 times (95% CI: 1.1-6.7; p = 0.04) more likely of having abdominal obesity when compared to those adequate in these lifestyle domains. CONCLUSIONS: Approximately one in four drivers had abdominal obesity and the "Nutrition" and "Type of Behavior" domains were associated with abdominal obesity.

How this classification was reachedexpand
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.
