Factors associated with sexual risk behaviour among young people in Ukraine.

We used data from a behavioural survey of Ukrainian men and women aged 14-24 to examine the relationship between nine potential risk factors and two HIV risk outcomes: non-use of condom at last sex, and multiple sexual partnerships. Younger age at first sex was positively associated with both health risk outcomes, and condom non-use at first sex was associated with subsequent non-use of condoms at last sex. There were regional differences in frequencies of both HIV risk behaviours. Compared with those who reported living in the place they were born, not living permanently at the current place of residence was associated with a fivefold increase in the odds of multiple partnership for women but not for men. Alcohol and drug use were associated with higher odds of multiple partnership and the effect was greater among women than among men. The data analysed are cross-sectional so cannot establish causality. More studies are needed to confirm these results and investigate causal relationships between the possible risk factors and the two health risk behaviours.
