Multiple Risk Behavior Interventions: Meta-analyses of RCTs.

Context: Multiple risk behaviors are common and associated with developing chronic conditions such as heart disease, cancer, or Type 2 diabetes. A systematic review, meta-analysis, and meta-regression of the effectiveness of multiple risk behavior interventions was conducted.

Evidence Acquisition: Six electronic databases including MEDLINE, EMBASE, and PsycINFO were searched to August 2016.

A systematic review on the clustering and co-occurrence of multiple risk behaviours.

Background: Risk behaviours, such as smoking and physical inactivity account for up to two-thirds of all cardiovascular deaths, and are associated with substantial increased mortality in many conditions including cancer and diabetes. As risk behaviours are thought to co-occur in individuals we conducted a systematic review of studies addressing clustering or co-occurrence of risk behaviours and their predictors. As the main aim of the review was to inform public health policy in England we limited inclusion to studies conducted in the UK.
