| Summary: | 碩士 === 輔仁大學 === 營養科學系碩士班 === 106 === It indicated that 56% of people eat food away from home (FAFH) at least once a day. Since FAFH tends to be more energy-dense, high in total fat, saturated fat, and sodium on a per-calorie basis, and lower in fruits & vegetables, eating out frequently may lead to poor dietary quality and cause obesity. Therefore, the aim of the study was to explore the association between frequency of food away from home, dietary quality and weight status among Taiwanese adults living in Taipei. This study had 101 subjects aged between 30 and 70. Food consumption was assessed by using a Taiwanese online food frequency questionnaire (Online FFQ). Body weight, body fat, BMI, and waist circumference were measured by body composition analyzer (IOI 353). Taiwan Dietary Index (TDI) was developed based on 2011 Taiwanese Dietary Guidelines and was scored from 0 to 100. The mean frequency of FAFH among Taiwanese adults living in Taipei was 9.7±5.9 times per week. The mean BMI and dietary scores were 24.3±3.9 kg/m2 and 63.4±9.5 respectively. People who had higher frequency of FAFH tended to be younger and had higher income. Subjects were divided into quartiles according to frequency of FAFH. Subjects in the highest quartile of FAFH frequency (>13.5 times/week) consumed less whole grains (p=0.01), nuts & seeds (p=0.02) and higher added sugar (p=0.01) than those who in the lowest quartile (<5.5 times/week). Subjects in the highest quartile of FAFH frequency had lower dietary score of whole grains (p=0.005), added sugar (p=0.05), and total dietary scores (p=0.03) than those in the lowest quartile. Total dietary scores was negatively associated with frequency of FAFH (r=-0.21) and waist circumference (r=-0.25). Frequency of FAFH was found to be positively associated with BMI in male. In summary, subjects who had higher frequencies of FAFH ate less whole grains, nuts & seeds and more added sugar. Accordingly it leaded to lower dietary scores of whole grains, added sugar and total dietary quality. Higher frequency of FAFH was associated with lower dietary quality and higher BMI in male. In addition, low dietary quality was associated with higher waist circumference.
