        Calcium intake has been insufficient in all age groups in previous Korean national surveys. This study was conducted to investigate calcium intake in Korean and American populations at different ages. We analyzed two national survey data: the 2007∼2009 Korean National Health and Nutrition Examination Survey (KNHANES) and the 2007∼2008 National Health and Nutrition Examination Survey (NHANES). Statistically, survey procedures were applied using the weight, cluster, and strata variables. The mean calcium intake of Koreans at ages of 1∼2 y, 3∼5 y, 6∼11 y, 12∼18 y, 19∼64 y, and 65+y was lower than American populations at those ages. The sufficient proportions based on Korean Estimated Average Requirement (EAR) of 1∼2 y, 3∼5 y, 6∼11 y, 12∼18 y, 19∼64 y, and 65+y in Koreans were 45.5%, 33.1%, 24.3%, 16.6%, 32.7%, and 19.0%. While the sufficient rates based on American EAR of 1∼3 y, 4∼8 y, 9∼13 y, 14∼18 y, 19∼30 y, 31∼50 y, 51∼70 y, and 71+y in US population were 88.5%, 54.4%, 35.2%, 35.8%, 55.3%, 55.2%, 40.6%, and 24.5%. Overall, the major foods contributing to calcium intakes in Koreans were milk, baechukimchi, and anchovies, whereas, milk products, pasta, or bread were major contributions to calcium in American populations. The calcium supplement intakes in the American population were 5.5 mg (1∼2 y), 15.5 mg (3∼5 y), 13.9 mg (6∼11 y), 35.7 mg (12∼18 y), 150.3 mg (19∼64 y) and 334.4 mg (≥65 y). These results suggest that Korean adolescents and older adults are the most insufficient in dietary calcium intakes among Koreans. In order to accurately estimate calcium intakes in Korean populations, calcium supplements and calcium-fortified foods should be considered.

        농촌지역에 거주하는 노인의 생선 섭취량과 인지기능저하 위험도 간의 상관성

        유아름(Areum Yu),김지혜(Jihye Kim),최보율(Bo Youl Choi),김미경(Mi Kyung Kim),양윤경(Yoonkyoung Yang),양윤정(Yoon Jung Yang) 한국영양학회 2021 Journal of Nutrition and Health Vol.54 No.2

        본 연구는 2009-2010년 양평지역에서 수행된 양평 코호트 자료를 활용하여 60세 이상 노인을 대상으로 생선 섭취량과 인지기능저하와의 상관성을 확인하였다. 여자 노인의 경우 생선섭취량이 높을수록 MMSE-KC 평균 점수가 높아지는 경향을 보였으나 (p for trend = 0.016), 남자 노인의 경우 유의한 차이가 나타나지 않았다. 또한 여자 노인의 경우 생선 섭취량이 높을수록 인지기능저하의 위험이 낮아지는 경향을 보였으나 (p for trend = 0.009), 남자 노인의 경우 통계적으로 유의한 결과가 나타나지 않았다. 여자 노인의 경우 생선 섭취량이 높을수록 항산화 비타민 (베타 카로틴, 비타민 A, 비타민 C, 비타민 E), 비타민 B군 (엽산, 비타민 B12), 지방산 (총 지방산, 포화지방산, 단일불포화지방산, 다불포화지방산, α-리놀렌산, EPA, DHA, 총 n-3 다불포화지방산) 섭취량이 높아지는 경향을 보였다. 남자 노인의 경우 생선 섭취량이 높을수록 항산화 비타민 (베타 카로틴, 비타민 A, 비타민 C, 비타민 E), 비타민 B군(엽산, 비타민 B12), 지방산 (총 지방산, 포화지방산, 단일불포화지방산, 다불포화지방산, α-리놀렌산, EPA, DHA, 총 n-3 다불포화지방산) 섭취량이 높아지는 경향을 보였다. 본 연구 결과 여자 노인에서 생선의 섭취가 많을 수록 인지기능저하 위험도가 감소함을 확인하였다. 향후 다양한 집단에서 생선 섭취량과 노인의 인지능력 간의 인과관계를 규명할 수 있는 종적연구가 필요하다. Purpose: This study examines the correlation between fish consumption and the risk of mild cognitive impairment in the elderly living in rural areas. Methods: The Yangpyeong cohort data collected from Yangpyeong in July 2009 and August 2010 was used as the data set. Adults greater than or equal to 60 years who have completed the Korean version of the Mini-Mental State Examination (MMSE-KC) were selected for the study. After excluding participants with less than 500 kcal of energy intake (n = 2), a total of 806 adults were enrolled as the final subjects. Cognitive function was assessed using the MMSE-KC, and dietary intake was collected using the quantitative food frequency questionnaire comprising 106 foods or food groups. Results: The educational level, proportion of people who exercise, fruits and vegetable intake, and energy intake, tended to increase with fish intake among men, while increasing age resulted in decreased fish consumption. Among women, the educational level, proportion of subjects who exercise, proportion of subjects currently taking dietary supplements, fruits and vegetable intake, and energy intake, tended to increase with fish consumption, whereas increasing age showed decreasing fish consumption. Increased fish intake resulted in a higher MMSE-KC score after adjusting for the confounding variables in women (p for trend = 0.016), but no significant trend was observed between fish intake and MMSE-KC score in men. Fish intake was inversely related to the risk of mild cognitive impairment after adjusting for covariates in women (Q1 vs. Q4; odds ratio, 0.46 [0.23-0.90]; p for trend = 0.009). Conclusion: This study determined that increased fish consumption is correlated with reduced risk of mild cognitive impairment in the female elderly. Further longitudinal studies with larger samples are required to determine a causal relationship between fish intake and cognitive function.

        한국 성인과 노인의 계절별 혈중 25-hydroxyvitamin D 농도와 비타민 D 급원식품 섭취빈도와의 관계

        유아름(Areum Yu),김지혜(Ji Hye Kim),권오란(O Ran Kwon),오세영(Se Young Oh),김정현(Jung Hyun Kim),양윤정(Yoon Jung Yang) 대한지역사회영양학회 2014 대한지역사회영양학회지 Vol.19 No.2

        This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults. Methods: Subjects were 10,374 adults and 2,792 older adults participating in the 2008- 2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research. Results: The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (≥ 20 ng/mL) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25 (OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk·dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream. Conclusions: Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.
