A study of sexual behaviour of teenagers is essential in the design of an effective intervention programme for sexually transmitted diseases (STDs). A questionnaire was administered to 380 men, attending the department for skin and venereal diseases in Belgrade in the period from January 2000 to June 2001. Two groups were compared, 'STD cases' (attending for suspected STDs) and controls (with skin mycotic diseases). In multivariate logistic regression analysis the following risk factors were significantly more frequent in STD cases: sex on the same day as the first encounter (odds ratio (OR)= 2.62, 95% CI = 1.58-4.34), history of previous STD (OR = 3.60, 95% CI = 1.74-7.45) and never using a condom with an irregular partner (OR = 2.19, 95% CI = 1.10-4.38).
