Metabolic syndrome is a clustering of medical conditions including high blood pressure, high blood sugar, abdominal obesity, high serum triglycerides, and low serum high-density lipoprotein(HDL), which is accompanied by the risk of developing cardiovascular disease, chronic degenerative disease, type 2 diabetes disease and cognitive disorder that threathen those patients'' health status.
Preventive intervention is needed to help metabolic syndrome risk group to form and practice healthy lifestyles for the prevention and early detection of metabolic syndrome.
This study is a descriptive research about the effect of metabolic syndrome risk group’s motivation for health behavior and optimistic bias on implementation of a healthy lifestyle. This study is conducted to provide basic data for an efficient nursing intervention program to enhance the implementation of desirable healthy lifestyle in metabolic syndrome risk groups.
This study was conducted by collecting 202 adults aged 40 or older from five health chekup centers of C hospital located in C City. The data used in this study were collected through structured surveys from January to September 2020.

The results of this study are as follows:

1. The average motivation for health behavior was 2.92 points, and the optimistic bias was 3.87 points on average, and the average for implementing a healthy lifestyle was 83.76 points.

2. The motivations for healthy lifestyle of the participants were significant depending on age(t=-2.37, p=.019), education level(t=-2.62, p=.009), and occupation(F=3.97, p=.020). Additionally, the optimistic bias was significantly different depending on experience(F=5.38, p=.005), subjective health conditions,(F=9.61, p<.001) and the presence of underlying diseases(t=-3.33, p=.001).

3. Motivations for healthy lifestyle related to the disease are dependent on waist circumference (t=2.07, p=.039). Optimistic biases differed significantly depending on the neutral fat(t=2.51, p=.013). The implementation of healthy lifestyles differed significantly depending on blood pressure levels(t=2.55, p=.011).

4. The motivation of health behavior of the study participants showed a positive correlation between the implementation of the healthy lifestyle (r=.60 and p<.001). Optimistic biases indicated a positive correlation between physical activity and weight control, a sub-region of healthy lifestyle practices (r=.23, p<.001).

5. Motives for health behavor(β=.562, p<.001) and blood pressure management(β=-.161, p=.004) were shown to be significant factors that affected the implementation of the healthy lifestyle of the participants, which means that motivation for health behavior and low blood pressure(normal range) are associated with implemetation of health lifestyle.

This study revealed that motivation for health behavior and the condition of blood pressure are factors that affect the implementation of healthy lifestyle of metabolic syndrome risk group.
Therefore, to improve the health life behavior of metabolic syndrome risk group, education and programs should be activated to promote and maintain proper healthy lifestyle for blood pressure risk group. The information on metabolic syndrome-related diseases, the course of treatment, prognosis and complications that may increase motivation for health behavior should be provided to continuous prison populations.

In addition, an education and support system should be established for those eligible for each age group and occupational group.
