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

Abstract

Objectives\nThis 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).\n\n\nMethods\nIn this cross-sectional study, a total of 4276 subjects (50∼64y: n\xa0=\xa02279, ≥65y: n\xa0=\xa01997) 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\xa0=\xa02070, <3 DDS\xa0=\xa0209) and 65 (≥3 DDS\xa0=\xa01534, <3 DDS\xa0=\xa0463) yrs or older.\n\n\nResults\nThe ≥3 DDS group had a larger proportion of subjects who were highly educated compared to <3 DDS group (P\xa0<\xa00.001). 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\xa0<\xa00.0001). 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\xa0<\xa00.05).\n\n\nConclusions\nThese 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.\n\n\nFunding Sources\nThis work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIP; Ministry of Science, ICT & Future Planning) (No. 2017R1C1B5017636).
