Background and aims: An evaluation was carried out of a general practice based weight control advice clinic to determine if clinically significant weight loss can be achieved and maintained in patients by this means. The weekly clinic was run by a health visitor for 8 years during which time 198 patients attended. Patients were seen individually by appointment on average between 1 and 4 weeks following referral by the GP, nurse or health visitor. The intervention was based on dietary and lifestyle advice. Methods: Short-term outcomes were determined from retrospective inspection of clinic data for all 198 patients. One hundred and five patients were followed-up at least 1 year after completion of the programme of clinic attendance and weighed to determine the long-term outcome. Results: One hundred and ninety-three (97%) patients achieved some weight loss during the programme, 33% achieved a 10% reduction in weight and 52% of patients achieved a reduction of BMI from above to below 30 kg/m2. Long-term follow-up showed that 6% patients maintained a 10% weight loss and 18% maintained a reduction of BMI from above to below 30 kg/m2. Conclusion: The results of this evaluation suggest that research on appropriate follow-up to enable patients to maintain weight loss is needed.
