The cost-effectiveness of weight management programmes in a postnatal population

Area of Science:

• Public Health
• Health Economics
• Maternal Health

Background:

• Postpartum weight retention is a significant concern, increasing risks of obesity and related health issues.
• Weight management interventions during the vulnerable postnatal period are crucial for long-term maternal health.
• Behavioral changes initiated postpartum can mitigate future excess weight gain.

Purpose of the Study:

• To estimate the cost-effectiveness of a weight management program for postpartum women.
• To assess the program's impact on weight loss and prevention of future obesity.
• To evaluate the program's value within a healthcare economic framework.

Main Methods:

• A mathematical model was developed using regression equations to predict weight change over 15 years postpartum.
• Data from a randomized controlled trial on program effectiveness and resource use were incorporated.
• The model utilized utility and mortality data by body mass index, adopting a lifetime horizon and NHS/PSS perspective.

Main Results:

• The weight management program resulted in a mean weight difference of 3.02 kg at 6 months and 3.53 kg at 15 years postpartum compared to the control.
• The incremental cost-effectiveness ratio (ICER) was calculated at £7355 per quality-adjusted life year (QALY) for married women.
• These results suggest the program is cost-effective within the National Institute for Health and Care Excellence (NICE) threshold.

Conclusions:

• The analyzed weight management program demonstrates cost-effectiveness for postpartum women.
• The findings support the integration of such programs into standard postnatal care.
• Acknowledged uncertainties in the analysis highlight the need for further research and validation.
