Sleep and cardiovascular disease.

This review centres around the recent evidence in examining the intersection of sleep and cardiovascular disease (CVD). Sleep in this review will be further subdivided to consider both sleep quantity and quality along and will also consider some of the more common sleep disorders, such as insomnia and obstructive sleep apnoea, in the context of CVD. Sleep disorders have been further explored in several specific populations which are both at risk of sleep disorders and CVD. Secondly, the review will present some of the risk factors for CVD that are affected by sleep and sleep disorders which include hypertension, diabetes, and obesity. It will also examine the potential underlying mechanisms including inflammation, appetite control, endocrine, and genetic processes that are affected by sleep and sleep disorders leading to increased risk of CVD development. In addition, we will consider the observed bi-directional relationships between sleep and cardiovascular risk factors. For example, obesity, a risk factor for CVD can be affected by sleep, but in turn can increase the risk of certain sleep disorder development which disrupts sleep, leading to further risk of obesity development and increased CVD risk. Finally, the review will explore emerging evidence around lifestyle interventions that have included a sleep component and how it impacts the management of CVD risk factor. The need for increased awareness of the health effects of poor sleep and sleep disorders will be discussed alongside the need for policy intervention to improve sleep to facilitate better health and well-being.

Imposing Compulsory Rugby Union on Schoolchildren: An Analysis of English State-Funded Secondary Schools.

Objective: To establish the extent to which Rugby Union was a compulsory physical education activity in state-funded secondary schools in England and to understand the views of Subject Leaders for Physical Education with respect to injury risk. Method: A cross-sectional research study using data obtained under the Freedom of Information Act (2000) from 288 state-funded secondary schools. Results: Rugby Union was delivered in 81% (n = 234 of 288) of state-funded secondary school physical education curricula, including 83% (n = 229 of 275) of state-funded secondary school boys' and 54% (n = 151 of 282) of girls' physical education curricular. Rugby Union was compulsory in 91% (n = 208 of 229) of state-funded secondary schools that delivered it as part of the boys' physical education curriculum and 54% (n = 82 of 151) of state-funded secondary schools that delivered contact Rugby Union as part of the girls' physical education curriculum. Subject Leaders for Physical Education also perceived Rugby Union to have the highest risk of harm of the activities they delivered in their school physical education curriculum. Conclusion: Notwithstanding discussions of appropriate measures (i.e., mandatory concussion training, Rugby Union specific qualifications and CPD) to reduce injury risk, it is recommended that Rugby Union should not be a compulsory activity given that it has a perceived high risk of injury and is an unnecessary risk for children in physical education.
