| Summary: | 碩士 === 臺灣大學 === 流行病學研究所 === 98 === Objective: According to the “Stepwise approach to chronic disease risk factor surveillance” (STEPS) of WHO, eight health behavior risk factors as 1.Tobacco use 2.Alcohol consumption 3.Diet 4.Physical activity 5.Raised blood pressure 6.Obesity 7.Blood glucose 8.Cholesterol account for chronic disease burden. Health behaviors play an important role in occurecne of chronic diasease, but it is unsure how health behaviors such as dietary habit lead to better HRQoL. We are interested in the relationship between those health risk factors and HRQoL. Besides, there is plentiful dietary culture in Taiwan, our study also aimed to analysis the the effects of diet habits on HRQoL.
Methods: The relationship between HRQoL measures and the health risk factors was assessed using data collected between 2006 and 2009 by dint of Li-Shin Outreaching Neighborhood Screening Cohort Study. We used the item from STEPS, selected eight health risk factors as covariates. HRQoL was measured by the 36-item Short From score. The impact of health risk factors on HRQoL was examined through a multiple linear mixed regression model. Furthermore, we used the factor analysis to define the dietary habit construct and examine the associated between dietary habit and HRQoL. Then we used three health behavior risk contructs to bulit the structure equation model.
Results: Intake of fruit and vegetable intake and exercise were statistically significantly associated with HRQoL after adjustment for the demographic factors. In the analysis of structure equation model, both regression coefficients of dietary habit construct on physical health quality of life and mental health quality of life were 0.0534(SE±0.0079) and 0.0578(SE±0.0081), which were statistically significant (P < 0.0001).
Conclusion: The health dietary habit is statistically significantly related to better HRQoL.
