The feasibility of a prisoner-led intervention to reduce smoking and improve diet and physical activity amongst prisoners

INTERVENTION: Using a randomised controlled design participants will be allocated 1:1 to intervention versus control arms. The peer‐intervention will be delivered to intervention arm participants over a 6‐week period and will involve these participants attending weekly group sessions run by trained prisoner facilitators. Control participants will receive standard care. The primary and secondary outcomes will be measured at baseline, immediately post‐intervention, 1, 3 and 6 months post‐intervention. The outcomes will be measured through self‐report via a questionnaire. Self‐reported smoking will be validated against participants’ objective carbon monoxide readings. BMI will also be measured for each participant. CONDITION: Non‐communicable disease risk‐factors ; Not Applicable PRIMARY OUTCOME: Smoking, diet and physical activity levels, measured through self‐report via a questionnaire at baseline, immediately post‐intervention, 1, 3 and 6 months post‐intervention SECONDARY OUTCOME: Well‐being, measured through self‐report via a questionnaire at baseline, immediately post‐intervention, 1, 3 and 6 months post‐intervention INCLUSION CRITERIA: 1. 21 years of age and over 2. If sentenced, the research participants must be in prison for the full duration of the intervention delivery 3. If remand, the research participants must be expected to be in prison for the full duration of the intervention delivery. 4. Mental capacity to provide consent to participate
