Abstract：Objective To develop Eating Habits Inventory (EHI) and study its reliability and validity. Methods A sample containing 943 people was investigated by sampling investigation method, and 32 of them were selected randomly and recompleted the inventory after 3 months. Results There are two dimensions in EHI, that are “Balanced Diet” and “Regularly and Moderately Eating”. The theory structure was confirmed by Exploratory Factor Analysis and the experts on this area. The Cronbach’s α coefficients were 0.82 and 0.67, the test-retest reliability were 0.73 and 0.55 (P<0.001), 3-month’s test-retest showed no significant difference (P>0.05). These data was analyzed by Stepwise Regression Analysis. Subjects from subhealth group had unhealthiest eating habits. Conclusion Eating Habits Inventory has a good reliability and validity, and is suitable for eating habits self-assessment for adult.

無論實踐經驗還是實證研究均表明飲食習慣與發(fā)育和健康關系密切[1-2]。全面、有效的飲食行為方式評估工具可用于危險因素的篩查、體質調養(yǎng)、疾病預防和干預等方面。中醫(yī)理論中有諸多關于飲食養(yǎng)生的論述,現代也有許多關于飲食保健的研究。本研究根據中醫(yī)飲食養(yǎng)生理論和現代研究結果,提煉可操作的行為指標,編制標準化的飲食方式調查表,用于成人飲食養(yǎng)生方式的評估醫(yī).學全.在.線網站www.gydjdsj.org.cn。
