Abstract

Background: In the context of increased health risks for individuals with underlying conditions due to the coronavirus disease 2019 (COVID-19) pandemic, this study investigated whether dietary improvements differ based on the diagnosis of chronic diseases.

Methods: This study used data from the Korea National Health and Nutrition Examination Survey from 2013 to 2021, including 45,391 individuals aged 19 years and older. Diet quality was assessed by the Korean Healthy Eating Index (KHEI) scores. The samples were stratified into subgroups based on the status and diagnosis of hypertension, type 2 diabetes mellitus, and dyslipidemia. Weighted linear regression was utilized to calculate the β coefficients and βdiff with 95% confidence intervals (CIs). Weighted differences in KHEI scores based on the diagnostic status were calculated.

Results: The weighted average KHEI score showed a declining trend in 2013-2019 (β, -0.46 [95% CI, -0.55, -0.36]) but an increasing trend in 2020-2021 (β, 1.24 [95% CI, 0.45, 2.02]), indicating a significant change in trend with the onset of the pandemic (βdiff, 1.70 [95% CI, 0.92, 2.49]). Individuals with hypertension, type 2 diabetes mellitus, or dyslipidemia had higher KHEI scores compared to those without these chronic conditions. Among individuals with these chronic diseases, those diagnosed had significantly higher average scores compared to those who were undiagnosed. During the pandemic, the disparity in average KHEI scores based on diagnosis status increased even further.

Conclusion: Diagnoses of hypertension, type 2 diabetes mellitus, and dyslipidemia appear to be positively associated with dietary improvements. During the COVID-19 pandemic, individuals aware of their chronic conditions were more attentive to their diets than those undiagnosed.

2013-2021年韩国慢性病诊断的饮食质量趋势:一项全国代表性研究
背景:在2019冠状病毒病(COVID-19)大流行导致有潜在疾病的个体健康风险增加的背景下,本研究调查了饮食改善是否会因慢性病的诊断而有所不同。方法:本研究使用2013年至2021年韩国国家健康与营养检查调查的数据,包括45,391名19岁及以上的个体。饮食质量是通过韩国健康饮食指数(KHEI)评分来评估的。根据高血压、2型糖尿病和血脂异常的状况和诊断将样本分为亚组。采用加权线性回归计算β系数和β差值,置信区间为95%。计算基于诊断状态的KHEI评分的加权差异。结果:2013-2019年加权平均KHEI评分呈下降趋势(β, -0.46 [95% CI, -0.55, -0.36]), 2020-2021年呈上升趋势(β, 1.24 [95% CI, 0.45, 2.02]),随着大流行的发生,趋势发生了显著变化(βdiff, 1.70 [95% CI, 0.92, 2.49])。与没有这些慢性疾病的人相比,患有高血压、2型糖尿病或血脂异常的人KHEI得分更高。在患有这些慢性疾病的个体中,那些被诊断出来的人的平均得分明显高于那些未被诊断出来的人。在大流行期间,基于诊断状况的KHEI平均得分差距进一步扩大。结论:高血压、2型糖尿病和血脂异常的诊断似乎与饮食改善呈正相关。在2019冠状病毒病大流行期间,意识到自己患有慢性病的人比未确诊的人更注意饮食。
