Purpose: This study was designed to find the correlations between physical activity and insulin resistance of the middle-aged adults. Methods: One hundred thirty one subjects participated in this study were age 40-60 from Y university's center for physical exercise in W city. The data were collected from August 5 to October 5, 2009. To measure physical activity, the contracted Korean version of the Self-Report of Physical Activity Questionnaires of IPAQ was used. Insulin resistance was measured using fasting glucose levels, serum insulin levels, and HOMA method (serum insulin${\times}$fasting glucose/22.5). Results: The continuous physical activity overall in this study was on average $1,792.30{\pm}2,216.81$ MET (min/week), and as a result of categorical classification: no activity was 66 subjects (50.4%); minimum activity, 41 (31.3%); and health-improving activity, 24 (18.3%), respectively. The overall degree of insulin resistance in these subjects was $2.20{\pm}2.62$(0.28-12.74). There was negative correlation between moderate intensity activity and insulin resistance (r= -.189, p<.05). Conclusion: These results revealed that promoting moderate-intensity physical activity is important in preventing and improving insulin resistance and possibly other metabolic risk factors in the middle-aged adults.

Purpose: This study was conducted in order to investigate the physical activities of vulnerable low-income middle-aged people and their associated factors. Methods: From a health behavior survey of 1,000 vulnerable low-income subjects from a public health center in a metropolitan city, a secondary analysis was conducted for 332 respondents who ranged in age from 40 to 64. Results: The prevalence of walking activity was 45.2% and that of moderately intense physical activity was 9.9%. Prevalence of walking activity showed a significant association with marital status (divorce/widowed/separated, OR=2.263), drinking (drinker, OR=0.430), and CES-D score (over 21, OR=0.434). Prevalence of moderately intense physical activity was greater in subjects who had two chronic diseases, compared with those who had no chronic diseases (OR=3.713). Conclusion: Findings of this study suggest a need for implementation of strategies to improve moderately intense physical activity of low-income, middle-aged people. Also, in addition to studies on socio-demographic and health status and their associations with physical activity, further studies of related factors affecting physical activity, such as self-efficacy, social support, and social networks as internal and external resources, are needed.

In this study, we have analyzed the 2015 KNHANES VI to understand the nutritional and health status of Korean middle-age adults from the perspective of frequency of eating breakfast. Those that eat breakfast five to seven times a week were 76.3 percent (male) and 72.7 percent (female). Frequency of eating lunch and dinner, and eating out was significantly higher among male subjects. The higher the frequency of eating breakfast, the higher the frequency of eating lunch, dinner and eating out. Female subjects that ate breakfast five to seven times a week had lower height and weight compared with other groups, but there was no significant difference of BMI and waist circumference among the four groups. Adults that eat breakfast five to seven times a week had consumed more carbohydrates, dietary fiber, phosphorus, potassium and vitamin C regardless of gender, which validates the nutritional benefits of eating meals regularly. Male adults that ate breakfast five to seven times a week revealed lower levels of diastolic blood pressure and LDL-cholesterol compared with other groups, which validates eating breakfast regularly was beneficial to their health. In conclusion, it is necessary to eat regular meals daily relative to the nutritional status and health of Korean middle-age adults.

Purpose: This study was conducted to identify the relationship of health status, aging anxiety, social networking, generativity, and happiness and to investigate the main factors influencing happiness of late middle-aged adults. Methods: The study collected data from a total of 153 middle-aged men and women aged 50 to 64 years old from a consumer panel of Macromill-Embrain, the biggest online survey provider in Korea. The data were analyzed using descriptive statistics, Pearson's correlation coefficient and a stepwise multiple regression using the SPSS 22.0 program. Results: The subjects' happiness mean score was 16.17±9.29. Statistically significant differences in happiness were found according to education (F=4.38, p=.014), economic status (t=5.13, p<.001), and religion (t=2.18, p=.031). Happiness was correlated significantly with health status (r=.41, p<.001), aging anxiety (r=-.62, p<.001), family support (r=.43, p<.001), friend support (r=.36, p<.001) and generativity (r=.63, p<.001). The factors influencing happiness of late middle-aged adults were generativity (𝛽=.37, p<.001), aging anxiety (𝛽=-.35, p<.001), family support (𝛽=.20, p<.001), and economic status (𝛽=.13, p=.033). The explanatory power of the model was 58.0%. Conclusion: This study will be used as basic data when developing a nursing intervention program for successful aging by identifying factors that affect the happiness of late middle-aged adults.

This study is aimed to examine effects of sociodemographic, social relation, and health related factors on risky drinking among early, middle, and older adulthoods. Using the sixth(2013-2016) National Health and Nutrition Examination Survey, separate logistic regression analyses were conducted for women's early adulthood (n=1,143), middle adulthood (n=1,306), and older adulthood (n=875) to test factors associated with risky drinking. For study results, as for women's early adulthood, education, marital status, employment, depressive feeling, and smoking were statistically associated with risky drinking. As for women's middle adulthood, only subjective stress level and smoking were associated with risky drinking. As for women's older adulthood, education, suicidal ideation, and subjective health condition were associated with risky drinking. These results found different factors influenced risky drinking according to life stages. Based on these results, convergent implications about reducing risky drinking according to life stages of women were discussed.

Objective : The purpose of this study was establishing clinical norms of TEMPA Korean version for Korean adult population in addition to identifying characteristics of hand function by age and gender based on the collected data. Methods : A total of 138 healthy adults between ages 20 and 59 were recruited by continuous sampling. All subjects had been employed TEMPA Korean version and Jarmar dynamometer and pinch gauge to evaluate hand function and strength. Results : The results showed that there were no statistically significant difference in overall hand function among the age groups and between genders. Also, while there were no significant differences in overall speed and qualitative movement, age groups of 40s and 50s showed a declining tendency in speed in some of the tasks. Also, hand strength increases up to 40s and start declining from the 50s, but most results did not show significant differences among the age groups. Conclusion : Normative data of TEMPA Korean version for Korean adult population was established, therefore, it can be used in clinical setting and research as evidence based. Furthermore, occupational therapists need to consider about the signs of decline in hand function and strength in middle-aged adults and to provide education programs to maintain their hand function.
