Combined effects of disease management and food insecurity on physical and mental health in Korean adults.

OBJECTIVE

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.
