A community pharmacy weight management programme: an evaluation of effectiveness

Area of Science:

• Obesity management
• Public health interventions
• Community pharmacy services

Background:

• Community pharmacies offer accessible platforms for weight management programs.
• Limited trials have assessed clinically significant weight loss outcomes with objective measures and 12-month follow-up.
• The Counterweight program was implemented in community pharmacies in Fife, Scotland, starting in 2009.

Purpose of the Study:

• To evaluate weight change in patients participating in the Counterweight weight management program delivered via community pharmacies.
• To assess the effectiveness of community pharmacy-based weight management interventions.

Main Methods:

• The Counterweight Programme targeted patients with a BMI ≥ 30 kg/m² or BMI ≥ 28 kg/m² with comorbidities.
• The program aimed for a daily energy deficit of 500–600 kcal, with training and materials provided by Counterweight dietitians.
• Pharmacy staff measured patient weight at each session, recording data for 3, 6, and 12-month follow-ups.

Main Results:

• 458 patients were enrolled between March 2009 and July 2012. Mean age was 54 years, and mean BMI was 36.1 kg/m².
• 10.2% of patients (on an intention-to-treat basis) achieved ≥5% weight loss at 12 months, with an average loss of 4.1 kg.
• No significant effect of sex, baseline BMI, or age on weight loss was observed.

Conclusions:

• The Counterweight pharmacy program demonstrates comparable effectiveness to other primary care weight management initiatives.
• Community pharmacy-based weight management should be considered as part of a comprehensive community service offering.
• This model provides an accessible approach to managing overweight and obesity in primary care settings.
