Measures to tackle drunkenness and alcohol-related violence in nightlife should expand beyond those targeted solely at nightlife environments. Continued disparities in pricing and policing of alcohol between on- and off-licensed premises may increase at-home drinking prior to nights out and alcohol-related problems in residential areas.

Within nightlife settings, youth violence places large burdens on both nightlife users and wider society. Internationally, research has identified risk factors for nightlife violence. However, few empirical studies have assessed differences in risk factors between genders. Here, a pan-European cross-sectional survey of 1,341 nightlife users aged 16 to 35 assessed a variety of risk-taking traits, including violence, sexual, alcohol, and drug-related current and historic behaviors. Results show that the likelihood of having been involved in a physical fight in nightlife increases with younger age, drunkenness, and increasing preference for tolerant venues for both genders. The odds of involvement in a fight for females who were drunk five or more times in the past 4 weeks were almost five times higher than those who were never drunk (odds ratio for males 1.99). Use of cocaine more than doubled the risk of involvement in violence among males. However, no association was found for females. For heterosexual men, the odds for violence almost doubled compared with bisexual or homosexual men, whereas for women heterosexuality was a protective factor. The effects of structural risk factors (e.g., bar and club characteristics) for nightlife violence differed by gender. To develop effective violence prevention measures in nightlife, considerations need to be made regarding the demographic composition of patrons in addition to wider structural elements within the nighttime environment.

High levels of substance use contribute to violence being a relatively common feature of young people's visits to international holiday resorts. To protect the health and well-being of holidaymakers and local populations in popular resorts, violence and substance use prevention must adapt to an increasingly globalized nightlife.

Introduction: Violence is increasingly recognised as a major public health issue yet health data are underutilised for describing the problem or developing responses. We use English emergency hospital admissions for assault over four years to examine assault demography and contribution to health inequalities. Results: Over 4 years, rates of admission increased by 29.56% across England. Admissions peaked on Saturdays (22.34%) and Sundays (20.38%). Higher rates were associated with deprivation across all ages, including those ,15 years, with a sixfold increase in admission rates between the poorest and wealthiest quintiles of residence. Logistic regression analyses indicate males are 5.59 times more likely to be admitted to hospital for assault and such admissions peak in those aged 15-29 years. Modelling based on national assault admissions and limited Accident and Emergency (A&E) data suggest that while more serious assaults requiring hospital admission have increased, assault attendances at A&Es have fallen. Discussion: Hospital admission and A&E data identify a direct contribution made by violence to health inequalities. Levels of violence inhibit other interventions to improve people's health through, for instance, outdoor exercise or delivery of health-related services in affected areas. With disproportionate exposure to violence in poorer areas even in those under 15, early life primary prevention initiatives are required in disadvantaged communities to reduce childhood harm and the development of adult perpetrators and victims of violence.Despite being considered primarily a judicial issue, violence, or the threat of violence, has major repercussions for the health of individuals and communities.
