6% of those who never got drunk; p < 0.001). Using illicit drugs, particularly “other illicit drugs,” both at home and on holiday was strongly associated with violence and unintentional injury. Both outcomes were also significantly associated with frequent use of nightlife (visiting bars and nightclubs) on holiday (Table 3). To identify independent relationships with violence and unintentional injury, logistic regression analyses

were conducted using all variables significant in bivariate analyses and a combined variable of nationality and location (Table 4). Here, odds of violence were highest in those visiting Majorca and in British visitors to Crete. Odds of unintentional injury were increased in visitors of both nationalities to Crete. Being male was associated with both outcomes, whereas find more younger

participants had increased odds of unintentional injury, but not violence. Participants who were attracted to their destination due to nightlife had increased odds of violence; Ponatinib nmr however, differences in violence between those with the lowest and highest levels of nightlife participation on holiday were not significant. Frequent drunkenness was associated with both violence and unintentional injury. Smoking and using any illicit drugs on holiday were associated with violence, but not unintentional injury. However, individuals who reported using drugs other than just cannabis at home showed increased odds of unintentional injury. Individuals who reported having been involved in violence on holiday were asked whether they were under the influence of alcohol or drugs at the time. Of those who provided this information (186 of 236), 91.6% reported being under the influence of alcohol. Of those involved in a fight who were drug users, 16.2% reported being under the influence

of drugs at the time of the fight. Over half (51.3%) of the violence occurred in bars or nightclubs, with the remainder largely (36.0%) occurring in streets. A growing body of research is identifying the risks young people take with their health during holiday periods and the problems they face particularly while away abroad. To our knowledge, however, this is the first study that has explored young holidaymakers’ substance use and PD-1 antibody experience of violence and unintentional injury across multiple destination countries and different nationalities. As with all surveys of risky and antisocial behaviors, our study may have been affected by compliance and underreporting or exaggeration of risk behaviors and experiences on holiday. However, we used an established methodology that ensured participants were informed of the purpose of the study and the topics it covered, assured of its confidentiality, and provided with a clearly anonymous mechanism of participation.
