Abbreviation: QoL: quality of life; DM: diabetes mellitus.
Notes: aPhysical component summary (PCS) measure of quality of life obtained using short-form (SF)−12 questionnaire.
bMental component summary measure (MCS) of quality of life obtained using SF-12 questionnaire.
cThe model was adjusted using regression with stepwise selection for sex, age, heart disease, DM, living status, education level, height, weight, waist circumference, exercise, PCS score, and MCS score.
dThe model was adjusted using regression with stepwise selection for age, heart disease, DM, living status, education level, height, weight, waist circumference, exercise, PCS score, and MCS score.
