A community-based health promotion intervention using brief negotiation techniques and a pledge on dietary intake, physical activity levels and weight outcomes: Lessons learnt from an exploratory trial

Abstract

Objective To assess the effectiveness of a brief face-to-face health promotion intervention which included a ̃pledge using brief negotiation techniques, compared with standard advice-giving techniques, delivered in a community setting. Design A parallel group pre-post design using randomised matched groups. Lifestyle helpers delivered the intervention (one consultation per participant). Diet, physical activity and anthropometric measurements were collected at baseline, 6 months and 12 months. Qualitative data were also collected. Setting Middlesbrough (UK). Subjects Adults living in low socio-economic areas. Results Recruitment and engagement of lifestyle helpers was difficult, and initial expectations that local health authority staff working in the community and community champions would act as lifestyle helpers were not realised. As a consequence, recruitment of participants was lower than anticipated. One hundred and twenty-eight adults were recruited and the retention rate was 48 % at 12 months. Barriers to participation included poor health and competing commitments. No significant differences in change in diet or physical activity behaviours, or BMI, between the intervention and control groups were observed. The control group had a significantly greater decrease in waist circumference at 12 months compared with the intervention group. Conclusions This exploratory trial provides important insights in terms of recruiting lifestyle helpers for community-based health promotion interventions, specifically (i) the priorities and limitations in terms of time (regardless of their general enthusiasm) for staff employed by the local health authority, and (ii) the willingness of potential community champions to serve their local community in areas where community identity and spirit - are seen as lacking. © 2012 The Authors.
