Investigation on Influencing Environmental Factors on Health Status of Korean Septuagenarians Dwelling in Longevity Region in Jeonla Province: Chung Shil Kwak, Miyong Yon, Mee Sook Lee, Se In Oh, Sang Chul Park; Korean J Community Nutr 2014;19(2):142-162. Published online April 30, 2014; DOI: https://doi.org/10.5720/kjcn.2014.19.2.142

OBJECTIVES
To evaluate the critical environmental factors on healthy-aging of Korean people, we investigated the significant factors influencing health status of septuagenarians living in rural area of Jeonla province, known to be one of the representative longevity regions in Korea.
METHODS
We divided subjects into healthy group (36M/25F) or poor-health group (26M/73F) based on self-reported health status, body mass index, a number of prescription, and blood test data. General characteristics, physical measurements, lifestyle, dietary behavior and nutrient intake, physical health and mental health data were statistically compared between the two groups.
RESULTS
Average age was not different between healthy group and poor-health group in men and women, respectively. In men, significantly favorable factors to health were observed to be higher education, regular exercise, higher grip strength and walking function, body mass index (> or = 18.5 kg/m2), moderate frequency of drinking and eating-out, non-smoking, normal red blood cell (RBC) count, higher serum dehydroepiandrosterone-sulfate (DHEAS) level, good digestive function and appetite, normal hearing function, regular meals, adequate vegetable and fruit intake, diverse food intake, adequate energy and nutrients (protein, vitamin B1, B6, C and E, folate, niacin, P, Zn and K) intake, higher mini-nutrient status assessment (MNA) score and low level of depression. On the other hand, in women, those were literacy, living arrangement, moderate frequency of drinking, healthy teeth, higher grip strength and walking function, bone mineral density, normal RBC and white blood cell (WBC) count, higher DHEAS concentration, higher MNA score, normal cognition and memory function, having snack and adequate fruit intake.
CONCLUSIONS
These results could be useful to plan effective strategies to increase health-life expectancy of Korean old people living in rural areas.

Assessment of Food Consumption, Dietary Diversity and Dietary Pattern during the Summer in Middle Aged Adults and Older Adults Living in Gugoksoondam Logevity Area, Korea: Miyong Yon, Mee Sook Lee, Se In Oh, Sang Chul Park, Chung Shil Kwak; Korean J Community Nutr 2010;15(4):536-549. Published online August 31, 2010

Abstract PDF: The purpose of this study was to investigate food intake, dietary diversity and dietary pattern during the summer in middle aged and older adults living in Gugoksundam (Gurye, Goksung, Sunchang and Damyang counties), Jeonla Province located in southern part of Korea and known as one of the representative Korean longevity areas. Food intake and dietary diversity were assessed by using the data from 2 day-24 hour recall of 1,051 subjects (394 males and 711 females) aged 45 years and older (45-93 years in male, 45-105 years in female). The average ages of males and females were 70.7 years and 71.1 years, respectively. Average total daily food intake was significantly decreased with aging in both genders, and the average animal food intake ratio to total food intake was ranged 10~14% in 3 different age groups, 45~64 years, 65~74 years and 75 years and older. The contribution of each food group, in weight, to total food intake showed the descending order of grains, fruits, vegetables and alcohols in males, and grains, fruits, potatoes and meats in females. On daily intake amount of each food item, rice, watermelon, soju, kimchi, and potato were ranked on top 5 in descending order in males, and rice, watermelon, potato, kimchi and ylmukimchi in females. On intake frequency, rice, kimchi, onion, green pepper and potato were ranked on top 5 in descending order in both genders. Dietary variety score (DVS) and dietary diversity score (DDS) for the assessment of dietary diversity and balance were significantly decreased with aging in both genders. In food group intake pattern (DMGFV), 01101 type without consumption of dairy and fruits was the most prevalent, and only 3.6% of male and 3.9% of female subjects showed 11111 type, consumed all the 5 food groups a day. Dietary pattern of subjects was analyzed by cluster analysis with 18 food groups intake. Overall dietary pattern was classified into two clusters, one was more desirable and the other was less desirable. The percentage of subjects with more desirable dietary pattern was about 15% in male and 32% in female. In conclusion, most of our subjects living in Gugoksundam area were taking very simple diet with low amount of dairy products and fruits. These results indicate that nutrition intervention and education for older people living in rural areas should be focused on various food intake including dairy products and fruits.

Age-related Circulating Inflammatory Markers and Cardiovascular Disease Risk Factors in Korean Women: Ho Kyung Kwak, Mi Joung Kim; Korean J Community Nutr 2009;14(4):451-461. Published online August 31, 2009

Abstract PDF: The purpose of this study was to investigate the age-related changes of cardiovascular disease risk factors and inflammatory markers in non-obese Korean women. Subjects were 112 women over 20 years old with body mass index (BMI) less than 30 kg/m2 and were divided into 3 groups (< 40 years, 40~59 years, > or = 60 years). Mean weight and BMI in the oldest group were significantly higher than those in the other 2 younger groups (P <0.05). Mean total cholesterol, triglyceride, LDL-cholesterol and apolipoprotein B/apolipoprotein A1 ratio (BAR) in the oldest group were significantly higher than those in the youngest group (P <0.05), and mean HDL-cholesterol of the oldest group was significantly lower than that of the youngest group (P <0.05). The older-aged group showed significantly higher mean values of atherogenic index (AI) and LDL/HDL ratio (P <0.05) than the respective younger-aged group, and AI was significantly correlated with age, nitric oxide and thiobarbituric acid reactive substances (P <0.01). In addition, mean vascular cell adhesion molecule-l (VCAM-1) tended to be higher in the older-aged group than the younger group. Tumor necrosis factor-alpha, a proinflammatory maker, was significantly positively correlated with serum homocysteine, a cardiovascular disease risk factor (P <0.01). In addition, a significantly positive correlation was observed between C-reactive protein and BAR (P <0.01). Overall results suggested that the aging might affect the increase of cardiovascular disease risk factors including the serum lipid profiles, weight and BMI, and age-related increases of weight and BMI might play a role in changes in certain biomarkers of inflammation.

Development of Nutrition Education Materials for Healthy Aging: Yun Ahn, Kyung A Kim, Hyunjoo Kang, Kyungwon Kim; Korean J Community Nutr 2006;11(6):740-749. Published online December 31, 2006

Abstract PDF: The objective of this study was to develop nutrition education materials for older adults, 'nutritional management for healthy aging'. A booklet and four leaflets were developed based on lesson plans. Topics of the lesson plans included eating habit assessment, Korean food guide pyramid, meal planning, eating sensibly and weight management. The titles of the leaflets were 'Eating right for healthy aging', 'Eat calcium-rich foods', 'Enjoy fruits & vegetables' and 'Weight management'. Illustrations and icons appropriate to the texts were designed using Illustrator 9.0 and Photoshop 6.0. Booklet (letter size, 5 chapters, 44 pages) and leaflets (B4 size, 6 sections) focused on modifying undesirable eating habits, providing practical tips for desirable behaviors, and behavioral modification such as recording in a food diary, goal setting and increasing self-efficacy. The drafts were pilot-tested by interviews with older adults(n=10), and minor changes were made. The characteristics of revised materials are as follows; i) materials focused on providing desirable eating behaviors for healthy aging, ii) messages were simple and specific, iii) large fonts(13 pt) were used and materials included interesting pictures and illustrations, iv) materials provided tips for balanced diets and recipes for older adults, v) materials included sections for participation of learners including assessment of nutritional risk factors and obesity, meal planning and games. The revised materials are self-explanatory and can be used by older adults and in nutrition education for older adults.

An Assessment of Socioeconomic Status and Physical Health Status of the Middle-aged Adults in Gangwha County: Eun Mi Kim, Yoon jung Choi, Oh Jun Kweon; Korean J Community Nutr 2006;11(6):725-739. Published online December 31, 2006

Abstract PDF: This is study was performed to assess socioeconomic status and physical health status of middle-aged men (40's~60's) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthropometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p=0.000) and most of them decreased according to age in educational levels (p=0.000) and family income (p=0.000), and prevalence of chronic diseases (p=0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in older males (p=0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%, 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p=0.015). Waist-hip ratio (WHR) increased in older males (p=0.028) and females (p=0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles, obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.
