Women in our sample reported more frequent risk behaviour at baseline and throughout their study participation, and had a significantly higher unadjusted incidence of HCV than men.
The implementation of the Lab-ARBAIS program to chemical engineering laboratory as a case study had shown a significant improvement on students' frequent at-risk behaviours.
Metcalf, Davey-Smith, Sterne, Heslop, Macleod and Hart [ 10] found a positive association between frequent job changes and risk behaviours for health, such as smoking, alcohol consumption and sedentary lifestyle.
This may indicate that the many respondents who had undertaken a risk behaviour were actually not frequent risk takers, but had a single exposure.
Relative risks (RRs) of being frequently bullied for violence/injury risk behaviours, and healthy lifestyle behaviours, and RRs of violence/injury for risk behaviours, and healthy lifestyle behaviours were calculated.
The most frequent risk factors associated with chlamydial infection are related to sexual behaviour, i.e. early age of first intercourse, multiple partners, and inconsistent condom use [ 1].
Furthermore, several research findings suggest that early sexual activity more likely reflects problems in adolescent development than successful rite of passage [ 32]: thus it has been found associated with other risk behaviours such as smoking tobacco, higher levels of drunkenness and cannabis use and frequent evenings out with friends [ 33].
Two-thirds exhibited multiple risk behaviours and 38% intended to change multiple risk behaviours.
Risk behaviours included smoking, alcohol use and sexual behaviour.
Three risk behaviours and three lifestyle behaviours were measured and recorded as dichotomous variables.
