Background: The aim of this study is to assess the relationships between familial types and dietary quality measured by the Korean Healthy Eating Index (KHEI) in representative Korean elderly.
Methods: We used cross-sectional data from 4,260 Korean elderly, aged over 65 years, who had participated in the 2016-2018 Korea National Health and Nutrition Examination Survey. The 14-item KHEI scores were cal- culated from the Food Frequency Questionnaire and the Dietary Habit Survey from the Nutrition Survey. Familial type was categorized into three groups of Live alone (LA), Live with a partner with or without other(s) (LP), and Live with other(s) without a partner (LO) based on the Household Interview Survey.
Results: LP had better dietary quality than LO for both sexes (both P<0.05). LA (64.5; standard error [SE], 1.0) had worse dietary quality than LP (66.7; SE, 0.6]) in elderly male (P<0.05) while they were not significantly dif- ferent in elderly female. The percentages of subjects having poor dietary quality (total KHEI score of ≤ 50) in LA, LP, and LO were 20.6% (SE, 2.7), 7.3% (SE, 0.8), 8.9% (SE, 3.6) in elderly male, and 9.6% (SE, 1.2), 5.7% (SE, 0.8), 12.9% (SE, 1.8) in elderly female, respectively. The multivariate-adjusted odds ratios of having poor dietary quality compared with LP was 2.45 (95% confidence interval [CI], 1.66-3.60) for LA male, and 1.98 (95% CI, 1.19- 3.28) for LO female.
Conclusions: Familial type affects dietary quality in Korean elderly. However, differential associations were shown between elderly male and female.
