Reducing the burden of falls and fall-related admissions to hospital and care homes is an important policy area. Falls cause significant injury leading to a reduced quality of life. We wanted to know if the environment around people’s homes changes the risk of falls for older people in Wales. We linked routinely collected, anonymised health data on...

Article
Air pollution (AP) is a significant environmental risk to human health. Historically, the impact of AP exposure has focused upon the physical health effects, yet the implications of AP on mental health have received limited attention. Despite this, recent research has highlighted emerging evidence supporting a possible aetiological link. The purpos...
Article
Full-text available
The uptake of COVID-19 vaccination in Wales is high at a population level but many inequalities exist. Household composition may be an important factor in COVID-19 vaccination uptake due to the practical, social, and psychological implications associated with different living arrangements. In this study, the role of household composition in the upt...
Article
Full-text available
Introduction: Gypsies and Travellers have poorer physical and mental health than the general population, but little is known about mental health service use by Gypsy and Traveller children and young people.
