Healthier Together: Implementation and evaluation of a co-designed, culturally tailored childhood obesity community prevention program for Māori and Pacific Islander children and families.

Issue Addressed: Co-designed and culturally tailored preventive initiatives delivered in childhood have high potential to close the cross-cultural gap in health outcomes of priority populations. Māori and Pacific Islander people living in Australia exhibit a higher prevalence of overweight and obesity and higher rates of multimorbidity, including heart disease, cancer and diabetes.

Methods: This mixed-methods, pilot implementation and evaluation study, aimed to evaluate the implementation of a community-based, co-designed and culturally tailored childhood obesity prevention program, using quantitative (pre-post anthropometric measurement, pre-post health behaviour questionnaire) and qualitative (semi-structured interview) methods. Sessions relating to healthy eating, physical activity and positive parenting practices were delivered to families residing in Brisbane (Australia) over 8-weeks.

Results: Data were collected from a total of 66 children (mean age 11, SD 4) and 38 parents (mean age 40, SD 8) of Māori and Pacific Islander background, from July 2018 to November 2019. Anthropometric changes included a reduction in Body Mass Index (BMI) z-score among 59% of children (median change -0.02, n = 38, p = 0.17) and BMI among 47% of adults (median change +0.06 kg/m, n = 18, p = 0.64). Significant improvements (p < 0.05) in self-reported health behaviours from pre- to post-program included increased vegetable consumption among children, decreased discretionary food intake of children, decreased discretionary drink consumption among both children and adults, increased minutes of daily physical activity among adults and increased parental confidence in the healthy diets of their children. Qualitative data revealed participants valued the inclusion of all family members, learning of practical skills and cultural tailoring delivered by the Multicultural Health Coaches.

Conclusions: This study provides preliminary evidence that the Healthier Together program improved self-reported health behaviours and physical activity levels among Māori and Pacific Islander children and their families in the short-term; however, due to the small sample size, these results must be interpreted carefully. The program empowered change via cultural tailoring and accessibility; however, long-term implementation and evaluation with a larger cohort is needed to validate the observed health behaviour improvements and their sustainability. SO WHAT?: The co-design framework that informed program development and key learnings of implementation will provide guidance to health practitioners, health workers, public health professionals and policy makers to develop inclusive and pragmatic co-design solutions for priority cultural populations in Australia. Health outcomes will improve as a result, promoting health equity for future generations.
