Association of Dietary Diversity with Health-related Quality of Life and Osteosarcopenic Obesity in Korean Female Adults (P18-059-19)

Abstract

ObjectivesThis study was conducted to evaluate the association of dietary diversity score with health-related quality of life and osteosarcopenic obesity in female aged 50 or older using data from the 2008∼2010 National Health and Nutrition Examination Survey (KNHANES). MethodsIn this cross-sectional study, a total of 4276 subjects (50∼64y: n = 2279, ≥65y: n = 1997) were classified according to dietary diversity score (DDS) (≥3 DDS, <3 DDS) using 24 h dietary recalls method. Body composition was evaluated using dual-energy X-ray absorptiometry (DXA) and health-related quality of life was assessed using EQ-5D (EuroQol five-dimension) index. Analysis was conducted by age-stratified groups: 50∼64 (≥3 DDS = 2070, <3 DDS = 209) and 65 (≥3 DDS = 1534, <3 DDS = 463) yrs or older. ResultsThe ≥3 DDS group had a larger proportion of subjects who were highly educated compared to <3 DDS group (P < 0.001). In the 65 yrs or older age group, age-adjusted means of EQ-5D index of ≥3 DDS group and <3 DDS group were 0.84 and 0.74, respectively and there was significant difference (P < 0.0001). However, in the 50∼64 yrs age group, no difference was observed in EQ-5D index according to the dietary diversity. The ≥3 DDS group had a larger proportion of subjects who had no osteosarcopenic obesity compared to <3 DDS group (P < 0.05). ConclusionsThese results suggest that the dietary diversity may be associated with a lower health-related quality of life and osteosarcopenic obesity in Korean female aged 50 years or older.
