Abstract

The general population is exposed to numerous environmental pollutants, and it remains unclear which pollutants affect the brain, accelerating brain aging and increasing the risk of dementia. The Environmental-Pollution-Induced Neurological Effects study is a multi-city prospective cohort study aiming to comprehensively investigate the effect of different environmental pollutants on brain structures, neuropsychological function, and the development of dementia in adults. The baseline data of 3,775 healthy elderly people were collected from August 2014 to March 2018. The eligibility criteria were age ≥50 years and no self-reported history of dementia, movement disorders, or stroke. The assessment included demographics and anthropometrics, laboratory test results, and individual levels of exposure to air pollution. A neuroimaging sub-cohort was also recruited with 1,022 participants during the same period, and brain magnetic resonance imaging and neuropsychological tests were conducted. The first follow-up environmental pollutant measurements will start in 2022 and the follow-up for the sub-cohort will be conducted every 3-4 years. We have found that subtle structural changes in the brain may be induced by exposure to airborne pollutants such as particulate matter 10 μm or less in diameter (PM10), particulate matter 2.5 μm or less in diameter (PM2.5) and Mn10, manganese in PM10; Mn2.5, manganese in PM2.5. PM10, PM2.5, and nitrogen dioxide in healthy adults. This study provides a basis for research involving large-scale, long-term neuroimaging assessments in community-based populations.

Summary

Korean summary
EPINEF 코호트는 환경유해인자에 의한 신경계 질환의 위해성을 평가하고, 환경유해인자로 유발되는 신경심리학적 기능 저하 또는 뇌 노화에 대한 근거를 제공하기 위해 2014년부터 50세 이상의 건강한 성인을 대상으로 시작되었습니다. 본 코호트는 뇌 영상학적 표지자와 인지 기능과 관련된 환경유해인자를 광범위하게 조사한 한국 최초의 장기 추적관찰 연구로, 대기 오염 물질 또는 다환방향족탄화수소 노출이 대뇌 영상표지자 및 신경심리학적 기능, 노인의 우울 증상에 대한 악화 요인으로서의 대기오염물질 노출과 결혼 상태의 교호작용 등의 연구결과들을 발표하였습니다. 또한, 추후에도 코호트의 지속적인 추적을 통해 환경유해인자 노출에 따른 신경학적 건강영향을 연구하여, 신경계 질환 관리를 위한 보건 정책 개선에 기여할 수 있을 것으로 기대됩니다.

Key Message
The EPINEF cohort was started in 2014 to assess the risk of neurological diseases caused by environmental harmful factors and to provide evidence for neuropsychological dysfunction or brain aging induced by these factors. This cohort is the first long-term follow-up study in Korea to extensively investigate brain imaging markers and environmental harmful factors related to cognitive function, and several related research results have been published. In addition, the follow-up survey will be continued in the future, and we expect that the results of the study will contribute to improving health policies for the management of neurological diseases.

Abstract

<sec><title>OBJECTIVES</title>The low-sodium diet is a known preventive factor for hypertension and cardiovascular disease. Factors associated with low-sodium diets should be identified to reduce sodium intake effectively. This study was conducted to identify factors correlated with a low-sodium diet.</sec><sec><title>METHODS</title>This cross-sectional study analyzed data from a total of 14,539 Koreans aged 20 years or older, who participated in the Fourth (2007-2009) Korean National Health and Nutrition Examination Survey. A low-sodium diet was defined as having ≤2,000 mg/day based on 24-hour recalls. Multiple logistic regression models were used to assess sex, age, education, number of family members, household income, occupation, alcohol drinking, total energy intake, frequency of eating out, and hypertension management status for their associations with low-sodium diets.</sec><sec><title>RESULTS</title>Among all participants, only 13.9% (n=2,016) had low-sodium diets. In the multivariate analysis, 40-49 years of age, clerical work jobs, higher total energy intake, and frequent eating out were inversely associated with low-sodium diets. And female sex and living-alone were associated with low-sodium diets. Lower frequency of eating out was significantly associated with low-sodium diets, even after adjusting for total energy intake and other potential confounders. Adjusted odds ratios (95% confidence interval) for a low-sodium diet were 1.97 (1.49-2.61), 1.47 (1.13-1.91), 1.24 (0.96-1.61), and 1.00 (reference) in people who eat out <1 time/month, 1-3 times/month, 1-6 times/week, and ≥1 time/day, respectively.</sec><sec><title>CONCLUSIONS</title>Our study suggests that sex, age, number of family members, occupation, total energy intake, and lower frequency of eating out were associated with a low-sodium diet in Korean adults.</sec>
