Abstract
OBJECTIVES
Although previous studies have investigated the correlation between fruit and vegetable consumption and depression, the results remain inconclusive. The present study aimed to investigate the association between weekly fruit and vegetable consumption and depressive symptoms in elderly Koreans.
METHODS
A multiple covariate linear regression analysis was performed using the data of 1,226 elderly individuals ≥ 60 years of age who participated in the Korean Elderly Environmental Panel II study from 2012 to 2014. Depressive symptoms were evaluated using the Korean version of the Short form Geriatric Depression Scale (SGDS-K). Generalized linear mixed-effects models were constructed to analyze the repeated measurements of 305 people who participated in the survey every year.
RESULTS
After adjusting for confounders, SGDS-K scores were negatively associated with the frequency of weekly fruit consumption as follows (β [95% confidence interval; CI]: -0.17 [-0.28 to -0.05], -0.17 [-0.27 to -0.07], -0.42 [-0.54 to 0.29], and -0.33 [-0.44 to -0.21]) for less than 1 time/wk, 1-3 times/wk, 4-6 times/wk, and daily, respectively, compared to no consumption. The SGDS-K scores were also negatively associated with the frequency of vegetable consumption (β [95% CI]: -0.86 [-1.18 to -0.55], -0.18 [-0.35 to -0.01], -0.36 [-0.53 to -0.18], and -0.15 [-0.29 to 0.00]) in the above order, respectively.
CONCLUSIONS
Fruit consumption was inversely associated with depression levels in a dose-dependent manner. Although there was no dose-response relationship between vegetable consumption and the level of depression, it was negatively associated with SGDS-K scores.

KEEP-II 데이터를 활용하여 한국 노년층의 주간 과일 및 채소 섭취 빈도와 우울증상 간의 상관관계를 알아보았다. 주중 과일을 섭취하는 빈도와 우울증상의 정도 및 우울증 이환 간에서 음의 상관관계가 있었으며 양반응관계가 나타났다. 채소 섭취 빈도의 경우에는 양반응관계가 나타나지 않았으나 채소 섭취 빈도와 우울증상의 정도 간에 음의 상관관계가 있었다.
Key Message
Weekly fruit consumption frequency was inversely associated with the level of depression in a dose-dependent manner in Korean elderly population who participated in KEEP-II study. Although there was no dose-response relationship between vegetable consumption and the level of depression, vegetable consumption frequency was negatively associated with the level of depression.

Abstract
OBJECTIVES
During the coronavirus disease 2019 (COVID-19) pandemic, crude incidence and mortality rates have been widely reported; however, age-standardized rates are more suitable for comparisons. In this study, we estimated and compared the age-standardized incidence, mortality, and case fatality rates (CFRs) among countries and investigated the relationship between these rates and factors associated with healthcare resources: gross domestic product per capita, number of hospital beds per population, and number of doctors per population.
METHODS
The incidence, mortality, and CFRs of 79 countries were age-standardized using the World Health Organization standard population. The rates for persons 60 years or older were also calculated. The relationships among the rates were analysed using trend lines and coefficients of determination (R2). Pearson correlation coefficients between the rates and the healthcare resource-related factors were calculated.
RESULTS
The countries with the highest age-standardized incidence, mortality, and CFRs were Czechia (14,253 cases/100,000), Mexico (182 deaths/100,000), and Mexico (6.7%), respectively. The R2 between the incidence and mortality rates was 0.852 for all ages and 0.945 for those 60 years or older. The healthcare resources-related factors were associated positively with incidence rates and negatively with CFRs, with weaker correlations among the elderly.
CONCLUSIONS
Compared to age-standardized rates, crude rates showed greater variation among countries. Medical resources may be important in preventing COVID-19-related deaths; however, considering the small variation in fatality among the elderly, preventive measures such as vaccination are more important, especially for the elderly population, to minimize the mortality rates.
Summary
Korean summary
국가별 발생률, 사망률, 치명률을 WHO 표준 인구로 연령표준화하였고, 의료자원과 관계된 지표와의 상관관계를 파악하였다. 2021년 4월 6일 기준, 연령표준화 발생률, 사망률, 치명률이 가장 높은 나라는 각각 체코 (10만명당 14,253명), 멕시코 (10만명당 182명), 멕시코 (6.7%)이며, 60세 이상 노인은 사망률과 치명률이 더 높은 것으로 나타났다. 1인당GDP, 인구당 의사 수, 인구당 병상 수는 발생률과 양의 상관관계가, 치명률과는 음의 상관관계가 있었고 노인에게서는 상관관계가 약하게 나타났다. 코로나바이러스감염증-19로 인한 피해를 최소화하기 위해서 의료자원의 투입과 더불어 노인의 감염예방이 중요할 것이다.
Key Message
The incidence, mortality, and case fatality rates of 79 countries were age-standardized using the WHO standard population. The correlations between the rates and the healthcare resource-related factors were investigated. As of April 6, 2021, the countries with the highest age-standardized incidence, mortality, and case fatality rates were Czechia (14,253 cases/100,000), Mexico (182 deaths/100,000), and Mexico (6.7%), respectively; the mortality and case fatality rates were higher among the elderly. GDP per capita, number of hospital beds per population, and number of doctors per population were associated positively with incidence rate, and negatively with case fatality rates: the correlations were weaker among the elderly. To minimize the burden caused by COVID-19, preventing the elderly from infection is important as well as supply of medical resources.
