Objective To examine associations between exposure to physical violence (PV) or sexual violence (SV) and adverse health behaviours among a sample of children in five African countries. Methods In a cross-sectional analysis of data from Namibia, Swaziland, Uganda, Zambia and Zimbabwe -countries that participated in the Global School-based Student Health Survey in 2003 or 2004 -we compared the relative frequency of several adverse health behaviours among children (primarily students 13-15 years of age) who did and who did not report exposure to PV or SV. We estimated odds ratios (ORs) for such behaviours and their 95% confidence intervals (CIs) after adjusting for age and sex. Findings Exposure to PV during the 12 months preceding the survey was reported by 27-50% (average: 42%) of the children studied in the five countries, and lifetime exposure to SV was reported by 9-33% (average: 23%). Moderate to strong associations were observed between exposure to PV or SV and measures of mental health, suicidal ideation, current cigarette use, current alcohol use, lifetime drug use, multiple sex partners and a history of sexually transmitted infection (P £ 0.05 for all associations). For example, the odds of being a current cigarette smoker were higher in children involved in one fight (OR: 2.20; 95% CI: 1.77-2.75), 2-5 fights (OR: 3.43; 95% CI: 2.54-4.63), or 6 fights or more (OR: 5.95; 95% CI: 4.37-8.11) (P for trend < 0.001) during the 12 months preceding the survey than in children unexposed to PV. Conclusion Childhood exposure to PV and SV is common among African children in some countries and is associated with multiple adverse health behaviours. In developing countries, increased awareness of the frequency of exposure to violence among children and its potential health consequences may lead to heightened attention to the need for health promotion and preventive programmes that address the problem.Une traduction en français de ce résumé figure à la fin de l'article.

SUMMARY BackgroundLittle is known about perinatal risk factors and coeliac disease.

SUMMARY BackgroundRegional studies in the UK indicate that the incidence of acute pancreatitis increased from the 1940s to the 1990s, while case fatality fell until the 1970s but has levelled-off since.

Objective To determine the implications of variation in mortality associated with use of weapons in different contexts. Design Literature review. Settings Armed conflicts and civilian mass shootings, 1929-96. Main outcome measure Mortality from wounds. Results During the fighting of war the number of people wounded is at least twice the number killed and may be 13 times as high; this ratio of the number wounded to the number killed results from the impact of a weapon system on human beings in the particular context of war. When firearms are used against people who are immobilised, in a confined space, or unable to defend themselves the wounded to killed ratio has been lower than 1 or even 0. Conclusions Mortality from firearms depends not only on the technology of the weapon or its ammunition but also on the context in which it is used. The increased mortality resulting from the use of firearms in situations other than war requires a complex interaction of factors explicable in terms of wound ballistics and the psychology of the user. Understanding these factors has implications for recognition of war crimes. In addition, the lethality of conventional weapons may be increased if combatants are disabled by the new non-lethal weapons beforehand; this possibility requires careful legal examination within the framework of the Geneva Conventions.

Drowning is a leading killer, particularly of children and young adults, yet has been greatly neglected. Despite accounting for a higher number of deaths than many other substantial public health issues, drowning has not benefitted from the targeted attention it requires, which is particularly tragic because low cost and effective drowning prevention interventions exist. Therefore, the recent UN General Assembly's adoption of a resolution on global drowning prevention is a historic first, and offers an exciting opportunity by providing a comprehensive framework and a practical roadmap that a range of actors and sectors, including governments, can follow to address the challenge of drowning prevention.
