接触食品服务机构被认为会鼓励消费，导致饮食质量下降，从而对健康状况不利。然而，对这些联系的经验验证仍然很少，特别是在年轻人和非西方人群中。这项横断面研究的目的是检验这一假设，即附近餐馆的可用性和外出就餐的频率与不良的饮食摄入模式相关，因此可能与日本年轻女性的体重指数（BM）和腰围较高有关。研究对象为989名年龄在18 ~ 22岁的日本女性饮食学学生。饮食摄入量和外出就餐的频率（即，使用综合的、自我管理的饮食史调查表评估前一个月期间的商业准备膳食消费）。邻里餐厅可用性被定义为居住地0.5英里（0.8公里）半径内的餐厅数量（即，全方位服务餐厅、有限服务餐厅和自助餐厅）。外出就餐频率的增加与肉类、糖果和面包以及膳食脂肪的摄入量增加，水果和蔬菜、大米和膳食纤维的摄入量减少以及膳食能量密度增加有关。然而，附近餐馆的可用性与外出就餐的频率或任何检查的饮食变量无关。此外，外出就餐的频率和附近餐馆的可用性与BMI或腰围无关。总之，虽然在一组年轻的日本女性中，外出就餐的频率与不利的饮食摄入模式呈正相关，但附近餐馆的可用性与外出就餐或饮食摄入的频率无关。
Exposure to food service establishments is considered to encourage consumption and contribute to poorer diet quality, and hence adverse health profiles. However, empirical verification of these links remains rare, particularly in young adults and non-Western populations. The objective of this cross-sectional study was to test the hypothesis that neighborhood restaurant availability and frequency of eating out are associated with unfavorable patterns of dietary intake and thus possibly higher body mass index (BM) and waist circumference in young Japanese women. The subjects were 989 female Japanese dietetic students 18 to 22 y of age. Dietary intake and frequency of eating out (i.e., consumption of commercially prepared meals) during the preceding month were assessed using a comprehensive, self-administered diet history questionnaire. Neighborhood restaurant availability was defined as the number of restaurants within a 0.5-mile (0.8-km) radius of residence (i.e., full-service restaurants, limited-service restaurants, and cafeterias). Increasing frequency of eating out was associated with higher intake of meat, confectionery and bread, and dietary fat, lower intake of fruit and vegetables, rice, and dietary fiber, and higher dietary energy density. However, neighborhood restaurant availability was not associated with either the frequency of eating out or any of the dietary variables examined. Further, frequency of eating out and neighborhood restaurant availability were not associated with BMI or waist circumference. In conclusion, although frequency of eating out was positively associated with unfavorable dietary intake patterns in a group of young Japanese women, neighborhood restaurant availability was not associated with frequency of eating out or dietary intake.
