Socioeconomic differences in the cost-effectiveness of a telephone-based intervention for obesity prevention in early childhood
Authors' conclusion
A telephone and SMS intervention was more cost-effective in low-SEP groups compared with high-SEP groups. Prioritizing families from socioeconomically disadvantaged backgrounds for this intervention will reduce healthy weight inequalities in childhood.
Study context
- Population
- Mothers of children aged 2–4 years; cohort of 4- to 5-year-old Australian children modelled until 17 years of age
- Comparison
- Telephone and short message service (SMS) support intervention, by socioeconomic position
- Outcome
- Incremental cost-effectiveness ratios (ICERs) per BMI unit avoided and per QALY gained, by SEP group
- Follow-up
- Until 17 years of age
