Adolygiad Sylfaenol NICE
Dywed yr awduron "This document is the summary of a ‘review of reviews’, which aims to bring together a large body of evidence and provide a critical and structured overview of the effectiveness of interventions and models to change attitudes, knowledge and behaviours in six different areas. This overview will provide researchers, policy and decision-makers, and practitioners with accessible, good quality evidence in these topic areas. The six health behaviours considered here are:
• Cigarette smoking
• Alcohol drinking (excluding alcohol dependency)
• Physical activity
• Healthy eating (excluding diet for weight loss)
• Illicit drug use (excluding drug dependency)
• Sexual risk taking in young people
The main objectives were to evaluate:
• Which are the most effective interventions to change knowledge, attitudes and health behaviours in each of these six areas?
• Is there any evidence to suggest that some interventions are effective / ineffective across the range of health behaviours?
• Which are the most effective models and approaches used in these interventions?
• What is the evidence for the effectiveness of interventions in targeting health inequalities within particular population sub-groups?
• What are the gaps in the evidence base?"

"Evidence statement for interventions targeting individuals:
All adults:
There is evidence of good quality (1++, A), that shows moderate evidence of effectiveness of individualised physical activity interventions for increasing (in the short term) self reported physical activity levels. However, other evidence of good quality (1 & 2+, A) indicates that most studies have no effect at the first follow-up (three months or more after the end of intervention).
There is evidence of good quality (1++, A), that shows a non-significant effect for reaching a predetermined threshold of physical activity (e.g., meeting current public health recommendations).
There is evidence of variable quality (1-, B), that shows an inconclusive effect of biomarker feedback or brief motivational interventions on physical activity.
There is evidence of good quality (1++, C), that show no effect of ‘stage of change’ based interventions on physical activity. There is evidence of good quality (1&2+, C), that shows a mixed and inconclusive effect of counselling interventions on physical activity.
Older People:
There is evidence of from two reviews (1++, A; 1-, C), that shows a small but shortlived effect of home-based, group-based, and educational physical activity interventions on increasing physical activity among older people."
