The objectives of this study were to determine whether older Americans would provide valid energy intake information using a 24-hr recall method and to determine which characteristics were predictive of under-report of energy intake. We conducted 24-hour recalls on 83 male and 105 female community-dwelling older adults(66-87y) in the USA to assess energy(EI) and nutrient intakes. Basal metabolic rate(BMR) was calculated from age-and gender-specific equations of Schofield. Under-reporting was defined a priori as EI : BMR<0.9. Subjects volunteered demographic information, underwent depression and cognition exams, and completed a Level II Nutrition Risk Screen. Differences between under- and adequate-reporters were assessed using t-tests for characteristics and macro-nutrient profile. Stepwise regression analyses were used to predict under-reporting status. Under-reporting of EI occurred in 34% of the sample. Neither geriatric depression scale(GDS) score, nor self-reported weight loss were related to under-reporting. On average, under-reporters had higher body mass indices. The most significant variables for the main effect to predict the ratio of energy intake to estimated basal metabolic rate(EI : BMRest) were BMI and age. Using a standard cut-off of 76% of the recommended dietary allowances for Americans, under-reporters were consistently more likely to be classified as having inadequate nutrient, as well as energy, intakes.

In this paper, we analyzed the effects of game-based visual feedback training on postural balance control in young adults and older adults. We provided postural balance training by 23 young adults and 14 older adults and for four weeks in fifth minute a day and three days a week using IBalance(Cybermedic Inc., Korea). We evaluated the ability of postural balance using balance SD(Biodex, medicalscience Inc., USA) for the validation of game contents based on visual feedback training program. The results showed that postural stability and limits of stability of young adults and older adults were improved significantly before and after the training(p<0.05). Thus, the games of postural balance encouraged anterior, posterior, medial, lateral and multidirectional weight shifting regarding postural balance. Our study indicates that postural balance training of visual feedback based game could be adapted for improving postural balance. Moreover, we could develope of game contents for individuals and various ages for effective application of this game-based visual feedback training.

The main purpose of this study was to examine the impact of religious participation on the depression of elder adults in USA. Specifically, this study examined how the influence of religious participation varied according to continuity or discontinuity of participation. Data from N=1,658 adults aged 65-90 who were respondents to two waves of the U.S. National survey of Families and Households 1987-1993 were used for these analyses. Depression was measured with a 12-item (of the original 20) modified version of the CES-D (Center for Epidemiological Studies-Depression). Multivariate regression models controlling for several demographic variables were estimated. Some clear evidence was found supporting activity theory and continuity theory That is, participating in a religious organization role at Time 2 but not Time 1 (T1 No - T2 Yes) and being continuously involved in religious organizations both at Time 1 and Time 2 (T1 Yes -T2 Yes) were associated with reduced depression, compared to continuous nonparticipation in religious organizations (71 No -72 No).

Purpose: This study was done to describe the correlation among the older Korean American adults's health-promoting behavior, life satisfaction and self-esteem. Method: The subjects consisted of 183 community-dwelling Korean immigrant elderly living in the state of Washington, USA. The instruments for this study were Health Promoting Lifestyle Profile(47 items), Life Satisfaction Scale(20 items) and Self-Esteem Scale(l0 items). Frequency, percentage, t-test, ANOVA, Duncan test and Pearson's correlation coefficient with SAS program were used to analyze the data. Result: 1) The average item score for the health-promoting behavior was 3.51; the highest score on the subscale was nutrition(M=3.63) with the lowest being exercise(M=3.07). 2) The average item score for the life satisfaction was 3.11. 3) The average item score for the self-esteem was 3.12. 4) Health-promoting behavior was significantly different according to educational level and participation in society circles. 5) Life satisfaction was significantly different according to age, religion and participation in society circles. 6) Self-esteem was significantly different according to age, marital status, religion and participation in society circles. 7) Health-promoting behavior was positively related to life satisfaction and self-esteem. The life satisfaction was positively related to self-esteem. Conclusion: It follows from this study that there is a very correlation among the older Korean American adults's health-promoting behavior, life satisfaction and self-esteem. Therefore health promoting programs that increase life satisfaction and self-esteem should be developed to promote a healthy lifestyle of the older Korean American adults.

Backgroud: Influenza vaccination is recommended for adults aged ${\geq}65$ years as they are at high risk of significant morbidity and mortality. This open-label, multicenter, post-marketing surveillance study assessed the safety of the MF59-adjuvanted trivalent inactivated subunit influenza vaccine, which is marketed as $FLUAD^{(R)}$ and $VANTAFLU^{(R)}$, in South Korean subjects aged ${\geq}65$ years. Materials and Methods: Solicited local and systemic adverse events (AEs) were collected from day 1 to 4 of the study. All unsolicited AEs and serious AEs (SAEs) were recorded from day 1 until study termination (day 29). Results: Of the 770 subjects enrolled ($FLUAD^{(R)}$, n = 389; $VANTAFLU^{(R)}$, n = 381), 39% overall experienced any solicited AE. Local AEs were reported by 33% of subjects overall; with the most common events being injection-site pain (30%) and tenderness (27%). Systemic AEs were reported by 19% of subjects overall with the most common events being myalgia (11%) and fatigue (8%). Conclusion: These results show that the MF59-adjuvanted influenza vaccine known as $FLUAD^{(R)}$ or $VANTAFLU^{(R)}$ had acceptable safety profiles in older adults (aged ${\geq}65$ years) in South Korea.

Purpose: The purpose of this study is to investigate the effects of older adult's head-turn gait on gait parameters by comparing with head oriented forward gait and to provide criteria for their risk of falling compared to young adult. Methods: The subjects were 19 young adults in their 20s and 18 older adults in their 60s or above residing in Daegu or Gyeongsangbuk-do. To evaluate their gait parameters, spatiotemporal gait parameters were measured using a gait analysis tool (Legsys, BioSensics, USA) under two conditions: 1) walking while keeping one's eyes forward and 2) walking while turning the head. The measurement for each test was performed after one practice session, and the mean value of three measurements was analyzed. The collected data were statistically processed using a two-way analysis of variance (ANOVA) to compare any differences in gait parameters between the two groups under the two conditions. The statistical significance level was set at α=0.05. Results: According to the comparison of gait parameters in young adult and older adult between the head oriented forward gait and head-turn gait, statistically significant differences were observed in two parameters: stride length according to the height ratio and stride speed obtained by dividing the stride length according to the height ratio by time (p<0.05). Conclusion: The results of this study indicate that the head-turn gait causes greater differences in stride length and speed among older adult than in young adult and therefore can act as a cause of falling.

This study was conducted to find the gender and age differences in dietary behaviors and food consumption pattern of Korean American adults living in western parts of USA. The structured survey forms and self-administered food frequency questionnaire were used to assess dietary behavior and nutrient intakes. It was found that younger subjects kept their meal time more irregularly and skipped breakfast more often than older subjects due to lack of time. There were significant age differences in skipping meals, kind of skipping meals, and the reasons for skipping meals. Young subjects consumed more American type food while older subjects consumed more traditional Korean food. Nutrient intakes of males' except for the elderly were significantly higher in energy, protein, Fe and P than those of females'. Vitamin A and vitamin C intake were significantly higher in females. Energy ratio of carbohydrate: protein: fat was 56.2 : 16.8 : 27.0. Females consumed more plant food as their dietary sources of protein, fat, Ca and Fe, compared to males. Ca intakes of participants' were below $75\%$ of RDA except for the youngest male and $30\~49$ aged male and females. Futhermore, Ca intake was below $70\%$ after age 50 in both genders. Effective nutrition education program targeting Korean Americans in the community should be developed and implemented to increase Ca consumption.

Objective: The purpose of this study was to compare the physical characteristics (bone mineral density, joint muscle strength) and running biomechanics between older adults and young adult runners to understand the changes of running strategy by aging. Method: Bone mineral density (Dual Energy X-ray Absorptiometry, USA) of lower lower extremity and muscle strength (Cybex Humac Norm [DEXA], CSMI, USA) were measured to identify the physical characteristics of 10 elderly (age: $67.70{\pm}3.30yrs$, height: $1.68{\pm}0.04m$, mass: $67.70{\pm}3.80kg$) and 10 young adults (age: $21.20{\pm}0.42yrs$, height: $1.73{\pm}0.06m$, mass: $72.11{\pm}4.15kg$). Running data was collected by using an instrumented treadmill (Bertec, USA) and 7 infrared cameras (Oqus 300, Qualisys, Sweden). Two-way repeated ANOVA analysis was used to analyze results at a significant level of .05 with Bonferroni post hoc analysis. Results: Compared to the young adult group, the elderly group showed statistically significant difference in physical characteristics and in running characteristics. Elderly runners showed lower BMD and muscle strength compared with young runners (p<.05). In the running parameters, elderly runners tend to show shorter contact time and stride length compared with young runners (p<.05). In the joint angles, elderly runners showed smaller range of ankle motion compared with young runners (p<.05). Finally, elderly runners showed lower level of joint moment, joint power, and GRF compared with young runners in each running speed (p<.05). Conclusion: The running behavior of the elderly performed periodic running was similar to many variables of young adults. However, there were noticeable differences found in the ankle joints and most kinetic variables compared with young adult runners. This discrepancy may propose that elderly runners should consider appropriate running distance and intensity in the program.

The sample of this study consisted of 140 informal caregivers who provided care to the older adults(over 60 years of age) in Great Cleveland, USA. Self-rated questionnaires were utilized to collect information. The purpose of the study was to identify coping strategies most frequently utilized by informal caregivers of older adults and to examine predictors of the caregivers' health responses to the caregiving situation applying Lazarus and Folkman stress model(1984). Stepwise multiple regression was used to identify significant predictors among caregivers' demographic-socio-economic factors, older adult's dependency of activities of daily living(ADLs), caregiver's appraisal to the caregiving situation, and coping strategies. Informal caregivers (N=140) included in the study utilized help-seeking and problem-solving coping strategies more than self-blame and minimization of threat coping strategies. Caregivers' responses to the caregiving situation were observed by caregivers' perceived physical health, depression and life satisfaction. For perceived physical health, threat appraisal, older adult's dependency on ADLs, existential growth coping strategy, and monthly income accounted for 25% of the variance. Caregivers who appraised the caregiving situation as more threatening, reported higher dependency on ADLs, used more existential growth coping strategy, and had higher monthly income reported better physical health. For depression, threat appraisal, stress appraisal, existential growth coping strategy, self-blame coping strategy, and monthly income accounted for 48% of the variance. Caregivers who used more existential growth coping and less self-blame coping, appraised the situation as less threatening, less stressful, and had higher monthly income reported less depression. For life satisfaction, self-blame coping, existential growth coping, monthly income, stress appraisal accounted for 49% of the variance. Caregivers who used more existential growth coping, less self-blame coping, less stress appraisal, lower monthly income reported better life satisfaction. In conclusion, informal caregivers in this study utilized positive coping strategies such as problem-focused, existential growth, help-seeking, rather than negative coping strategies including self-blame. When they utilized positive coping strategies more often, caregivers experienced higher perceived physical health, higher life satisfaction and lower depression. Therefore, nursing intervention which utilized positive coping strategies is needed to enhance informal caregivers to have positive health responses to the caregiving demands.
