As part of the Nutrition CRSP Mexico project conducted in rural villages in highland Mexico, this study examined whether nutritional factors, family characteristics, and the duration of schooling were associated with cognitive performances in 107 schoolers(53 boys and 54 girls) aged 8~10. Food intake was measured by recall, direct observation and weighment twice monthly over the course of a year. Families were characterized in terms of socioeconomic status and parental cognitive performance, education and aspiration. Dietary quality, but not energy intake, and anthropometry (wt-for-age, ht-for-age, head circumference) were significantly associated with cognitive test results for both verbal and performance measures. When the effect of SES is controlled using partial correlation, the relationships were substantially weakened. Sex differences were also found in response to nutritional deprivation. Among boys, dietary quality was the most important indicator of cognitive performance, while household economic conditions were more importantly associated with cognitive performance among girls. Participation in schooling was important for cognitive skille as it related to nutritional status.

Purpose: To investigate the instrumental activities of daily living (IADL), leg muscle strength, cognitive and visual functions according to the participants' demographic characters and experiences of falling in Korean elder who are residents in the community. Method: Data were collected from 351 participants aged 65 or more, who were ambulatory, A structured questionnaire and several physical function measurements were used to collect the data which were analyzed using the SAS program. Results: The participants' IADL scores were significantly different according to their age, educational level and living situation. The leg muscle strength of the elders were significantly different according to gender and age, and were also related the risk of falling. Cognitive scores were significantly different according to gender, age, education level and marital status. Visual acuity and depth perception were significantly different according to age, education level, and marital status. Conclusion: Demographic variables and experience of falling were identified as variables related to IADL, leg muscle strength, cognitive and visual function of elders. Further study with a larger and nation-wide sample is needed to identify the variables related to the physical and cognitive functions of elders.

This study was done to investigate the relationship of socioeconomic status and food intake to cognitive status of the older population. The subjects of this study consisted of 214 older persons aged 60 - 84 years. Interviews were conducted using the health-related habits and food frequency questionnaires to provide basic information for nutrition education program. We evaluated the current food consumption-pattern and cognitive status of the subjects. The results of this study were as follows： Mean age of the subjects was 69.7${\pm}$7.4 years. The average cognitive function score of the subjects was 7.9${\pm}$2.0 (full score was 10.0). Male had a higher cognitive status score than female. There was significant difference between cognitive status score and age, education level, pocket money, physical activity and family type. The subjects who had a higher cognitive status score ate more fish and meats group and milk and milk products than the subjects that had a lower cognitive status score. These results have demonstrated that various socioeconomic variables and food intake pattern affect on cognitive status with aging and suggest that proper nutrition education and adequate nutrient intake in quality and quantity are essential in maintaining cognitive status in later life.

The purpose of this research Is to inquire into the aspects of consumers' perception of age and their lifestyle and to reveal the effect of variability in spending behaviors themselves. A survey was carried out regarding the consumers of the new elderly generation aged 55 and above. 561 respondents were surveyed. residing in Seoul and Metropolitan areas. Factor analysis from the exploratory reconnaissance, Cronbach's $\alpha$, K-average community and multivariate analysis, multi-recurrence and crossing analysis($\chi^2$ verified), were used for statistics analysis. In conclusion, the cognitive age only shared a marginal relationship with lifestyle, most people in their forties stood out in this part of the research. The change of the cognitive age and lifestyle of the new elderly generation is expected to be a variable in the clothing purchasing behavior in the future. As the population of the new elderly generation increases, there is a need for changing views towards the new elderly generation and there is no doubt that it is a main target within marketing trends in the elderly generation industry.

Background: There is increasing concern that moderate preterm (32-33 weeks' gestation) and late preterm (34-36 weeks' gestation) birth may be associated with minor neurodevelopmental problems affecting poor school performance. Purpose: We explored the cognitive function, cognitive visual function, executive function, and behavioral problems at school age in moderate to late preterm infants. Methods: Children aged 7-10 years who were born at 32⁺⁰ to 36⁺⁶ weeks of gestation and admitted to the neonatal intensive care unit from August 2006 to July 2011 at the National Health Insurance Service Ilsan Hospital were included. We excluded children with severe neurologic impairments, congenital malformations, or chromosomal abnormalities. Neuropsychological assessments consisted of 5 neuropsychological tests and 3 questionnaires. Results: A total of 37 children (mean age, 9.1±1.2 years) participated. The mean gestational age at birth was 34.6±7.5 weeks, while the mean birth weight was 2,229.2±472.8 g. The mean full-scale intelligence quotient was 92.89±11.90; 24.3% scored between 70 and 85 (borderline intelligence functioning). An abnormal score was noted for at least one of the variables on the attention deficit hyperactivity disorder diagnostic system for 65% of the children. Scores below borderline function for executive quotient and memory quotient were 32.4% and 24.3%, respectively. Borderline or clinically relevant internalizing problems were noted in 13.5% on the Child Behavior Check List. There were no significant associations between perinatal factors or socioeconomic status and cognitive, visual perception, executive function, or behavior outcomes. Conclusion: Moderate to late preterm infants are at risk of developing borderline intelligence functioning and attention problems at early school age. Cognitive and executive functions that are important for academic performance must be carefully monitored and continuously followed up in moderate to late preterm infants.

노년기의 사회적 관계와 인지기능은 상호 밀접한 관계가 존재한다. 사회적 관계(social relation)는 구조적 특성과 이에 대한 인지적 정서적 평가를 반영하는 질적 특성으로 구분되며, 최근 노년기의 사회적 관계와 관련하여 사회적 고립(social isolation) 개념이 부각되고 있다. 사회적 고립은 사회연결망, 가구형태, 사회참여 등 객관적 차원과 지각된 사회적 지지에 대한 결핍과 외로움 등 주관적 차원으로 구분되는 다차원적인 이론적 구조를 가진다. 노년기 대인관계갈등 역시 인지기능과 밀접한 관계가 존재한다. 본 연구에서는 사회적 관계의 구조적 특성을 나타내는 객관적 사회적 고립과, 질적 특성을 나타내는 주관적 사회적 고립, 대인관계갈등이 노년기 연령집단별 인지기능에 미치는 주효과와 상호작용효과를 검증하였다. 분석자료는 KSHAP 1차조사부터 3차조사까지 총 1,740명의 패널자료를 활용하여, 무선효과 패널로짓모형을 적용하여 분석하였다. 분석결과는 다음과 같다. 첫째, 노년기 연령증가에 따라 인지기능 저하는 급격하게 증가하는 경향성이 나타났다. 객관적 주관적 사회적 고립은 모두 80세를 변곡점으로 U자형의 분포가 나타났다. 아울러 배우자, 자녀 친척, 이웃 친구 노년기 연령증가에 따라 대체적으로 감소하는 분포가 나타났다. 둘째, 인지기능저하에 대한 주효과는 객관적 주관적 사회적 고립과 정적으로 유의미하게 나타난 반면, 대인관계갈등 유형은 유의미하게 나타나지 않았다. 셋째, 노년기 인지기능저하에 영향을 미치는 이원상호작용효과 분석결과, 주관적 사회적 고립과 인지기능저하와의 관계는 배우자와의 갈등수준별로 유의미하게 다른 것으로 나타났다. 또한 주관적 사회적 고립을 많이 느낄수록 연소노인(65~74세)에 비해 초고령노인(85세 이상)의 경우 인지기능저하가 급격하게 높아지는 것으로 나타났다. 본 연구결과에 기초하여 노년기 연령집단별 인지기능 저하를 감소시키기 위한 정책적 실천적 시사점을 제시하였으며, 연구의 한계점과 추후연구를 위한 제언에 대해 논의하였다.

This study starts from the question, "Are people of the age 60 and over equally 'old?' "As the aging population has rapidly become a global issue, it is a timely question to think about whether it is appropriate to classify people aged 60 and over as senior citizens monolithically based on their chronological age. Thanks to the advancement of medical technology and ever-increasing life expectancy, there may be more differences than we thought in terms of cognitive and behavioral patterns among the elderly population. In order to further investigate this question, this study focuses on technology acceptance behavior of 132 participants over the age of 60 towards a wearable healthcare device. The results show that there were interesting behavioral differences among participants depending on their cognitive capabilities. More specifically, participants with high cognitive capability (Superagers) consider the usefulness and the social aspects (social norm and image) of using wearable healthcare technology. Whereas for those with relatively low cognitive capability (non-Superagers), usefulness of using the technology was not a significant factor, and they mainly considered social norm and image. Our findings imply that the current monolithic application of chronological age to classify the elderly population should be carefully reconsidered because people aged over 60 years old may not always share homogeneous cognitive and behavioral patterns.

Purpose: The purpose of this study was to find out the degree of cognitive function among the elderly and to confirm its correlated factors. Methods: The subjects consisted of 392 elderly people over the age 65 who were living in Busan. Data were collected by the interview method, using a structured questionnaire and the K-MMSE scale. Results: The average points of the elderly's cognitive functions measured by K-MMSE were 23.76(${\pm}4.02$). With the cut-off point for cognitive impairment set as 24 points below using K-MMSE scale, 38.8% of the subjects have cognitive impairments. Among the variables related to cognitive functions, literacy showed the highest correlation with cognitive function(${\beta}=.330$, t=7.249, p<.001), followed in order by educational level, age, depression level, attendance of elderly's college, and religious activity. The total explanatory power of these variables is 36%. Conclusion: In order to prevent cognitive impairment among the elderly, elderly people have to maintain social relationships continuously, and expand the social network by participating in the related programs. Some efforts to prevent the occurrence of depression and to stimulate patients' brain activity need to be recommended.

This study was conducted to find sensitive indicator of food intake and specific food group related to cognitive function and to analyze the pathway among factors affecting food intake and cognitive function of the aged. 179 people over 50 years old were investigated and all the data were analyzed by SPSS 10.0 package. Food frequency was more sensitive indicator to show the relationship between food intake and cognitive function of the aged than the numbers of standard amount of food eaten. Consumption of grains and starch, meat, fish, eggs and beans were strongly related to cognitive function of the aged and intake of vegetables and fruits also have relationship with it. Moreover, the more frequent eating the carbohydrate and the protein, the higher the cognitive level of the aged. Age, education period, income, blood pressure, duration after retirement, frequency of physical activity and BMI were correlated with food intake and cognitive function of the aged. Among them, age and frequency of physical activity were most strongly correlated with food intake, and education period with cognitive function of them. This investigation shows that more stable intake of carbohydrate and protein containing foods need to be supplied to low income aged and the importance of physical activity of the aged must be emphasized with food intake for better life of the aged.
