Social and psychosocial factors associated with high-risk sexual behaviour among university students in the United Kingdom: a web-survey.

In the UK there are limited data about university students' risky sexual behaviour. A cross-sectional web-survey was conducted to investigate factors associated with high-risk sex among students at two UK universities. High-risk sex was reported by 25% of 1108. High personal sexually transmitted infection (STI) risk perception and permissive attitudes towards casual sex were associated with high-risk sex for both men (odds ratio [OR]: 12.12; 95% confidence interval [CI]: 4.10-35.81; OR: 2.49; 95%CI: 1.11-5.56, respectively) and women (OR: 22.31; 95% CI: 9.34-53.26; OR: 3.02; 95% CI: 1.82-5.01, respectively). For men, drinking alcohol (OR: 17.67; 95% CI: 1.90-164.23) and for women age and frequent drinking (OR: 2.02; 95% CI: 1.05-3.89; OR: 1.89; 95% CI: 1.08-3.31, respectively) were associated with high-risk sex. However, perceiving an average student as more likely to contract STIs (men, OR: 0.34; 95% CI: 0.16-0.75) or HIV (men, OR: 0.44; 95% CI: 0.20-0.96; women, OR: 0.42; 95% CI: 0.28-0.63) and finding it difficult to discuss sexual matters (women, OR: 0.60; 95% CI: 0.39-0.91) were negatively associated with high-risk sex. Most of the factors found were similar to other populations, but some psychosocial factors showed complex patterns of association that require further investigation.

Food poisoning among clients of a meals on wheels service.

Sixty-one out of 105 elderly people who received a meal from a meals on wheels service developed a diarrhoeal illness. Twenty-seven of the 61 were admitted to hospital and three died. Epidemiological evidence suggested that food poisoning was associated with eating strawberry mousse made with raw eggs. Salmonella enteritidis phage type 4 was identified as the causative organism.
