The purpose of this study was to measure the level of expectations regarding aging (ERA) and identify relationship between ERA and physical activity of middle aged adults.

Participants were middle aged adults who resided in the community in three cities in Korea. Data were collected using questionnaires that contained items on individual characteristic, International Physical Activity Questionnaires (IPAQ), and behavior-specific cognitive factors including ERA-12. Hierarchical multiple regression was conducted to examine whether ERA would predict physical activity by controlling other factors.

The mean age of the participants was 51.1±6.9 years. The mean score for ERA (possible range=0 to 100) was 40.04±14.31. More than half of the participants (62.6%) were not engaged in health promoting physical activity. Gender, employment status and exercise confidence were associated with level of physical activity (F=7.14, p<.001, R²=.36). After controlling for individual factors and behavior-specific cognitive factors, ERA was independently related to physical activity (F=7.19, p<.001, R²=.38).

The results demonstrate that individuals' belief about aging has effects on physical activity in Korean middle aged adults. Thus, nursing interventions which focused on ERA could help enhance physical activity in middle aged adults.

This study was done to assess the level of physical activity among Chinese immigrant women and to determine the relationships of physical activity with individual characteristics and behavior-specific cognition.

A cross-sectional descriptive study was conducted with 161 Chinese immigrant women living in Busan. A health promotion model of physical activity adapted from Pender's Health Promotion Model was used. Self-administered questionnaires were used to collect data during the period from September 25 to November 20, 2012. Using SPSS 18.0 program, descriptive statistics, t-test, analysis of variance, correlation analysis, and multiple regression analysis were done.

The average level of physical activity of the Chinese immigrant women was 1,050.06±686.47 MET-min/week and the minimum activity among types of physical activity was most dominant (59.6%). As a result of multiple regression analysis, it was confirmed that self-efficacy and acculturation were statistically significant variables in the model (p<.001), with an explanatory power of 23.7%.

The results indicate that the development and application of intervention strategies to increase acculturation and self-efficacy for immigrant women will aid in increasing the physical activity in Chinese immigrant women.
