Combined effects of disease management and food insecurity on physical and mental health in Korean adults
AbstractObjective:The present study aimed to examine the combined effects of disease management and food insecurity on physical and mental health in a representative Korean population.Design:A cross-sectional study.Setting:Data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2012–2015.Participants:Adults aged ≥30 years (n 17 934) who participated in the KNHANES.Results:Among health-care factors, unmet health-care needs and mental health counselling were different by food insecurity status, with a higher prevalence in adults with food insecurity. The prevalence of underweight was higher in men with food insecurity (5·9 %), whereas the prevalence of obesity was higher in women with food insecurity (37·4 %), than that in men and women with food security. Food insecurity was associated with a high risk of all mental health outcomes. For the combined effects of disease management and food insecurity, unmet health-care needs was related to increased risk of obesity for food-insecure men (Pinteraction = 0·029) and lack of participation in nutrition education or counselling was related to increased risk of obesity for food-insecure women (Pinteraction = 0·010). In addition, higher unmet health-care needs in adults with food insecurity was related to higher risk of mental health outcomes.Conclusions:Unmet health-care needs may exacerbate obesity for food-insecure men and mental health problems for both food-insecure men and women. In addition, lack of participation in nutrition education or counselling may exacerbate the obesity for food-insecure women.
