Current smoker (current smoker vs non-smoker/ex-smoker); regular exercise (5 or more days per week for at least 10 min per day/any vigorous and moderate physical activities); private practice (private solo/private hospital/non-government organisation); public practice (university/government/hospital authority/not applicable); at-risk drinkers (>3 AUDIT-C score), the AUDIT-C score was calculated by the sum of score based on the frequency of drinking alcohol, the average number of standard drinks per day and the frequency of taking five or more drinks on one occasion, ranging from 0–12. The frequency of drinking alcohol (less than once per month/once per month/two to three times per month or once per week/two to three times per week/four to six times per week or every day) was ranked 0–4, respectively; the average number of standard drinks per day (one to two drinks/three to four drinks/five to six drinks/seven to eight drinks/nine or more drinks) was ranked 0–4, respectively; the frequency of taking five or more drinks on one occasion (never/less than once per week/monthly/weekly/daily or almost daily) was ranked 0–4, respectively.
