Linear regression model adjusted for covariates that were significantly associated with the outcome. The covariates were gender (female/male), area (rural/urban), socioeconomic status (low/middle/high), age groups (13–17 /18–24 /25–44 /≥45 years) and tobacco use (never user/user). Q1–SES excluded; Q2–age group excluded; Q3–gender/SES excluded; Q4–gender/SES/tobacco use excluded; Q5–SES/tobacco use/age group excluded; Q6, 7, 8–age group and tobacco use excluded. Bold numbers indicate significance (p<0.05).
