Statistics were carried out using Logistic regression. adjusted for age, sex, self-pay of cancer screening, weight variation, waist-height ratio, physical activity, drink, smoking.
MODEL 1 non-adjusted.
MODEL 2 age, sex.
MODEL 3 age, sex, smoke, exercise, education levels, income status, calcium intake.
MODEL 4 age, sex, smoke, exercise, education levels, income status, calcium intake, PTH (or vitamin D).
*The cut-off values for the 4th quartiles of PTH was 76.8 pg/ml in male and 77.6 pg/ml in female.
