Purpose: The purpose of this study was to investigate the effect of olfactory stimulation on the balance ability of the elderly. Design: Randomized controlled trial. Methods: A total of 20 subjects were randomly assigned to the olfactory stimulation group (2 males and 8 females) and deception olfactory stimulation group (3 males and 7 females). Subjects were subjected to 30 second 3 times olfactory stimulation and deception olfactory stimulation, and the assessment measured pre and post postural distance and postural speed. Results: In the elderly, the olfactory stimulation group was significantly improved the postural distance and postural speed in the eyes closed state than the deception stimulation group (p<.05). Conclusion: As the information is provided through the olfactory stimulation, the postural distance and postural speed are significantly improved. therefore, it is expected that the olfactory stimulation in the elderly will be an effective intervention method to prevent fall.

Studies on the health problems of the elderly have been increased with increasing life expectancy of Koreans. To assess the health status of people over 50 years old including the elderly (678 free-living people: men (168), women (510)), anthropometric measurements and biochemical nutritional status were analyzed. General characteristics and the prevalences of specific diseases were also examined. The mean anthropometric values for males and females were heights of 162 cm and 149 cm, respectively; and weights of 59 kg and 52 kg, respectively, which were much lower than the Korean standards established in the Korean Recommended Dietary Allowances. The mean BMI, WHR (waist hip ratio), and body fat rate (%), which are obesity indices, were significantly higher in females than in males. As the age went up, height, weight, lean body mass, and mid-arm circumference decreased. Whereas, blood pressure (SBP) for women increased. Mean blood HDL-cholesterol levels of men and women were 46.0 mg/dl and 46.3 mg/dl, respectively; their triglyceride levels were 129.1 mg/d1 and 135.6 mg/dl, respectively, which were not significantly different. Total cholesterol and LDL-cholesterol levels were significantly higher in females than in males. For man there were significantly different in ${\gamma}$-GTP, Na levels by age. As the age went up for women, RBC, hemoglobin, hematocrit, HDL-cholesterol, ${\gamma}$-GTP and $Ca^{2+}$ levels significantly decreased. Levels of total protein and albumin were above the lower normal limit for the majority of the participants. Prevalence of anemia, assessed by hemoglobin using World Health Organization (WHO) definition, was 43.9% for men and 42.1% for women. Also, many of the subjects were out of the normal range in total cholesterol (women), HDL-cholesterol, TAS (total antioxidant status), APase, RBC, hemoglobin, hematocrit levels. Therefore, measures to improve the biochemical nutritional status for the people in rural area are required.d.

In this study, nutrient intake status and energy expenditure were examined to investigate the nutritional status of the elderly in a rural community. The results obtained by questionaries, the 24 hour recall method, and time-diary were as follows: The elderly men surveyed were 73.8 years old, on the average. The elderly women surveyed were 73.5 years old, on the average. The proportion of the elderly with diseases was 51.9%. Most of the subjects (86.1%) had a regular meal pattern of consuming three meals a day. The average daily energy intake of the rural elderly was much lower than the Korean RDA. The dietary assessment data showed that each energy intake of the males and the females was 79.5% and 84.3% of the RDA, respectively. The dietary intake of Ca, Fe, niacin, thiamin, and riboflavin was lower than the Korean RDA, and that of P and Vitamin C was adequate. The Fe intake was significantly different with respect to age and sex (p < 0.05). Although, in both elderly men and elderly women it decreased with age, the elderly men's intake was lower than the elderly women's. The heights of the elderly men and the elderly women was 159.7 cm and 147.5 cm, respectively, and the weights were 60.0 kg and 52.2 kg, respectively, and the BMI was in the moderate range. Heights significantly decreased with age (p < 0.05). According to daily living schedules, leisure time (11.0 hour) was the longest, physiological time (9.6 hours) was next, and work time (3.4 hours) was the shortest. Energy expenditure significantly decreased with age (p < 0.01). Energy intake also decreased with aging. Energy balance (energy expenditure/energy intake) was 93.4% in elderly men and 104.0% in elderly women. Especially, in elderly men in the 65 to 74 age range, the energy balance was the lowest, and the nutrient intake was also much lower than that of elderly women.

The purpose of this study was to assess activation and contribution of muscles of the elderly according to increased loading during the arm flexion extension resistance exercise. Surface electromyographic signals were acquired from biceps brachii, triceps brachii, deltoid posterior, pectoralis major and latissimmus dorsi to determine the difference of the activation of specific muscles between the elderly and young. Five elderly and five young males with no musculoskeletal disease volunteered for the study. Electromyographic activities in the muscles were measured during resistance exercise and normalized to the maximum EMG activity recorded in the maximal voluntary static contraction (MVC). Against the increased loading during arm flexion/extension resistance exercises, the young uses muscles evenly but the elderly uses one specific muscle frequently. Contribution of triceps brachii during extension and deltoid posterior during flexion was principal in the elderly.

This study was designed to investigate and quantify components of the connotative meaning of foods, and to analyze the correlations between food concepts and food frequencies on elderly Korean. It involves adapting a communications research tools, the semantic differential and demonstrating its use with two population groups, urban and rural aged. The data were collected by interviewing 217 males and females of 70 years of age and older living in urban and rural areas. To assess how they feel and what they know about foods, the instrument which contains concepts of price, taste, goodness of health, interest, usuality, likes and dislikes, appetite, fattening, quality, and nutritive value about foods were developed. The result shows that there are significant correlations between food concepts and food frequencies. The more affirmative concepts the elderly have, the more food frequencies tend to be. positive concepts are appeared on the meat, fishes, vegetables & fruits, Kimchi and the rice, but negative connotations are appeared on the milk and sugar. There are significant differences between the urban and rural elderly on food concepts.

This study identified hazard exposures, health problems, and job satisfaction among elderly agricultural workers. A total of 1,340 agricultural workers (1,079 males and 261 females) were extracted from the 6^th Korean Working Conditions Survey data. Three age groups (A: 40s or below, B: 50s, and C: 60s or above) were statistically compared in hazard exposures, health problems, and job satisfaction. Elderly agricultural workers (60s or above) had significantly more exposure to ergonomic hazards, severe health problems, and lower job satisfaction than young agricultural workers. The study findings may help understand the characteristics of hazard exposures, health problems, and job satisfaction of elderly agricultural workers and will be useful for improving these conditions.

The purpose of this study was to assess the nutrition education program for older adults at rural area. Eighty three adults (mean age ;55.6$\pm$11.9) participated in nutrition education program. Data collection includes serum and urine collections for health state. The impact of nutrition KAP (knowledge attitude and practice) and retention was examined among participants who were assessed at program entry 3 times of education and 1 month of follow-up. The results were as follows : The participants were composed 52 persons of under 60-year-old and 31 persons over 60 years. Of the 83 participants, 60 were females and 23 were males. Serum albumin and calcium content of females (3.5$\pm$1.2g/dl, 7.5$\pm$3.9mg/dl) were significantly lower than males(4.7$\pm$0.9g/dl, 11.2$\pm$4.6mg/dl). Serum TG and cholesterol contents of females (143$\pm$117mg/d1, 205$\pm$31mg/d1) were higher than males (101$\pm$86mg/dl, 192$\pm$19mg/dl) but not significantly different. The calcium (13.4$\pm$9.0mg/dl) and urea (743$\pm$440mg/dl) contents of urine excretion were also significantly lower in female than in males (19.7$\pm$11mg/dl, 1041 $\pm$535mg/dl). Via the question of nutrition attitude, the participants improved significantly between pre and post education (the score of pre, post and after 1 month, 6.7$\pm$1.8, 7.2$\pm$1.5, 7.2$\pm$1.8), and were also attributed to better personal feeling health by modified CMI test but food habit was not significantly improved. As the differences of age and gender groups were compared, under 60-year-old group had better nutrition practice score than over 60 years group.

In recent years, the number and proportion of Korean elderly have grown rapidly, and elderly individuals show a disproportionate risk for poor nutritional status. The purpose of this study was to examine the relationship of sociodemographic background to nutrient intake of persons 65 years of age or older, living in 15 cities in Korea. Data on 1973 subjects (603 males, 1370 females), who participated in the Korean Elderly Nutrition Survey (2000), were analyzed. Their mean age was 72.3 years and their mean body mass index (BMI) was 24.2 kg/$m^2$. Basic sociodemographic data were obtained through personal interviews. The 98-item semi-food frequency questionnaire, developed and previously validated for Korean middle-aged and elderly subjects, was administered. “Percentage of subjects who consumed under 75％ Korean RDA,” “number of nutrients consumed below 75％ Korean RDA,” “mean nutrient adequacy ratio,” and “nutrient density” were used to determine nutritional status. Male elderly had better nutritional quality than female elderly. Nutritional quality decreased with age, especially in older elderly (over 75). Elderly who were underweight (BMI 〈 20 kg/$m^2$) showed poorer nutritional quality than those who were normal weight (BMI 20∼25 kg/$m^2$) and overweight (BMI $\geq$ 25 kg/$m^2$). Elderly who lived alone had significantly poorer nutritional quality than those who lived with a spouse, and/or with children. Lower education level and economic dependence also showed lower nutritional quality. A stepwise multiple regression analysis was performed to examine the effects of specific sociodemographic factors on nutritional quality. For number of nutrients under 75％ RDA as a dependent variable, education level explained 4.8％ of the variance, followed by living status, age, body mass index, gender, and living expense support (Model $R^2$ = 0.091). For mean nutrient adequacy ratio as a dependent variable, model $R^2$ was 0.098. Therefore, sociodemographic variables such as gender, age, body mass index, living status, educational level, and economic status influenced elderly nutrition status. These results indicate that an elderly nutrition intervention should focus on subjects who are poorly educated, living alone, age 75 or older, and/or underweight.
