研究低收入非洲裔美国人（AA）家庭中食物不安全，超重，心理社会因素和食物行为之间的关联。B 'More儿童健康社区（BHCK）肥胖预防试验基线评估参与者的横断面调查。我们收集了有关社会经济因素、食物来源目的地、获取食物、准备方法、社会心理因素、信仰和态度、参与粮食援助计划、人体测量学和粮食安全的数据。我们使用主成分分析来识别食物来源目的地的模式和逻辑回归来研究关联。巴尔的摩市的14个低收入，主要是AA社区。298例成人-儿童（10-14岁）二对儿。41.6%的家庭存在某种程度的粮食不安全，12.4%的家庭经历过某种程度的饥饿。有饥饿感的粮食不安全参与者失业和收入较低的可能性更大。我们发现，成人和儿童的超重率（超重和肥胖）很高（82.8%和37.9%的食物不安全，没有饥饿; 89.2%和45.9%的饥饿），尽管安全状况没有显着差异。食物来源的使用模式，食物的收购，准备，知识，自我效能和意图没有不同的粮食安全。粮食安全与健康食品是负担得起的和方便的观念有关。更大的照顾者身体满意度与食物不安全和超重有关。在这种情况下，肥胖和粮食不安全是主要问题。对于许多粮食不安全的家庭来说，对健康食品的看法可能会成为他们购买和消费的额外障碍。
To examine associations between food insecurity, excess body weight, psychosocial factors and food behaviors among low-income African-American (AA) families. Cross-sectional survey of participants in the baseline evaluation of the B’More Healthy Communities for Kids (BHCK) obesity prevention trial. We collected data on socioeconomic factors, food source destinations, acquiring food, preparation methods, psychosocial factors, beliefs and attitudes, participation in food assistance programs, anthropometry and food security. We used principal component analysis to identify patterns of food source destinations and logistic regression to examine associations. Fourteen low-income, predominantly AA neighborhoods in Baltimore City. 298 adult caregiver-child (10–14 years old) dyads. 41.6% of households had some level of food insecurity, and 12.4% experienced some level of hunger. Food insecure participants with hunger were significantly more likely to be unemployed and to have lower incomes. We found high rates of excess body weight (overweight and obese) among adults and children (82.8% and 37.9% food insecure without hunger; 89.2% and 45.9% with hunger, respectively), although there were no significant differences by security status. Food source usage patterns, food acquisition, preparation, knowledge, self-efficacy and intentions did not differ by food security. Food security was associated with perceptions that healthy foods are affordable and convenient. Greater caregiver body satisfaction was associated with food insecurity and excess body weight. In this setting, obesity and food insecurity are major problems. For many food insecure families, perceptions of healthy foods may serve as additional barriers to their purchase and consumption.
