The Coordinated Approach to Child Health (CATCH) program is a cost-effective investment, demonstrating significant net benefit and favorable cost-effectiveness ratios for childhood obesity prevention.

Area of Science:

  • Public Health Interventions
  • Health Economics
  • Childhood Obesity Prevention

Background:

  • Assesses the economic value of the Coordinated Approach to Child Health (CATCH) program.
  • Utilizes parameter estimates from the El Paso trial for analysis.
  • Employs standard economic measures: cost-effectiveness ratios (CER) and net benefit (NB).

Purpose of the Study:

  • To determine the net benefit and cost-effectiveness of the CATCH intervention.
  • To estimate intervention costs per quality-adjusted life years (QALYs) saved.
  • To compare the present value of averted future costs with the CATCH intervention cost.

Main Methods:

  • Calculated CER using societal perspective on costs.
  • Estimated QALY weights using National Health Interview Survey (NHIS) data.

  • Predicted avoided adult obesity cases (ages 40-64) using National Health and Nutrition Examination Survey (NHANES) data and a lifetime obesity progression model.

    • Main Results:

    • CATCH intervention found to be cost-effective and net beneficial.
    • CER was US$900 (US$903 for Hispanic parameters), well below the US$30,000 benchmark.
    • NB was US$68,125 (US$43,239 for Hispanic parameters), exceeding the US$0 threshold.
    • Results remained robust across sensitivity analyses.

    Conclusions:

    • School-based childhood programs like CATCH represent valuable investments.
    • Inclusion of Hispanic parameters lowered both NB and CER due to wage differences.
    • Economic benefits for Hispanic populations remained within established cost-effectiveness and net benefit thresholds.
