Studies A-Z > B > Booster
A randomised controlled trial and cost-effectiveness evaluation of booster interventions to sustain increases in physical activity in middle-aged adults in deprived urban neighbourhoods.
Research summary
This study assesses whether it is worth providing further support, three months after giving initial advice, to those who have managed to do more physical activity.
Study candidates (n=1,500) will initially be given an interactive DVD, supported by advice from a trained facilitator. The facilitator will provide two telephone follow-ups at one-month intervals. Only those who have increased their physical activity at this point (n=600) will be randomised into the study. These participants will receive a "mini booster" (n=200), a "full booster" (n=200) or no booster (n=200).
The "mini booster" consists of two telephone calls one month apart to discuss physical activity and usage of the DVD. A "full booster" consists of a face-to-face meeting with the facilitator at the same intervals. The purpose of these booster sessions is to help the individual maintain their increase in physical activity.
We will measure the differences in physical activity, quality of life and costs associated with the booster interventions, three months and nine months from randomisation. The research will be carried out in 20 of the most deprived neighbourhoods in Sheffield. These locations have large, ethnically diverse populations, high levels of economic deprivation, low levels of physical activity, poorer health and shorter life expectancy.
Participants will be recruited through general practices and community groups, as well as by postal invitation to ensure the participation of minority ethnic groups and those with lower levels of literacy.
Sheffield City Council and Primary Care Trust fund a range of facilities and activities to promote physical activity and variations in access to these between neighbourhoods will make it possible to examine whether the effectiveness of the intervention is modified by access to community facilities. A one-year integrated feasibility study will confirm that recruitment targets are achievable based on a 10 per cent sample.
