The power of partnerships: state public health department multisector collaborations in major chronic disease programme areas in the United States.

Background: Multisector collaboration between state public health departments (SHDs) and diverse community partners is increasingly recognized as important for promoting positive public health outcomes, addressing social determinants of health, and reducing health inequalities. This study investigates collaborations between SHDs in the United States and different types of organizations addressing chronic disease in and outside of the health sector.

Methods: SHD employees were randomly selected from the National Association of Chronic Disease Directors membership list for participation in an online survey. Participants were asked about their primary chronic disease work unit (cancer, obesity, tobacco, diabetes, cardiovascular disease, and others), as well as their work unit collaborations (exchange of information/cooperation in activities) with organizations in health and non-health sectors. As a measure of the different organizations SHDs collaborated with in health and non-health sectors, a collaboration heterogeneity score for each programme area was calculated. One-way analysis of variance (ANOVA) with Tukey's post hoc tests were used to assess differences in collaborator heterogeneity between programme areas.

Results: A total of 574 participants were surveyed. Results indicated that the cancer programme area, along with diabetes and cardiovascular disease, had significantly less collaboration heterogeneity with organizations outside of the health sector compared to the obesity and tobacco programme areas.

Conclusions: While collaborations with health sector organizations are commonly reported, public health departments can increase collaboration with sectors outside of health to more fully address chronic disease prevention.
