Learning Objective 1: The learner will be able to understand the predictors of health practice behaviors among adults and middle-aged group.

Learning Objective 2: The learner will be also able to consider the predictors of health behavioral practices when they design health promotion program in advance.

Purpose: Due to the increased average life-expectancy, an interest in healthy life of adult and middle-aged groups has been rapidly increased in Korea. Thus, this study aimed at identifying predictors of health practice behaviors(HPBs) and comparing predictors between adult and middle-aged groups. 

Methods: Data were obtained from Korea National Health and Nutrition Examination Survey(KNHANES) 2005. A total of 21,757 were selected for this study(an adult group: 13,283, a middle-aged group: 8,474). In addition to demographic information, data on HPBs such as smoking, drinking, physical activity, body weight control, hours of sleeping, regular meals, and snacking were used. The total score of HPBs was calculated by adding the scores of each item. The possible scores ranged from 0 to 7. Stepwise multiple regression analysis was used to identify predictors of HPBs in each group. 

Results: BMI was identified as a most significant predictor. Also, more HPBs were performed when living with spouse, and the quality of life was higher in an adult group. Gender, marital status, and BMI were identified as significant predictors in a middle-aged group. An adult group showed more HPBs performed when aged and had higher quality of life compare to a middle-aged group. Gender was a significant predictor in an adult group: Females performed HPBs more compare to males. 

Conclusion: To improve the healthy life, the health promotion programs designed for each group should include the predictors found in this study.
