目的：本研究的目的是测试家庭粮食不安全访问量表（HFIAS）在衡量坦桑尼亚农村家庭粮食不安全方面的结构效度、内部一致性和收敛效度，并确定与家庭粮食不安全相关的社会经济特征。设计：2008年2月和3月进行了关键知情人访谈和横断面调查。农村伊林加，坦桑尼亚：主题：关键的线人采访了21个有目的地选择的男性和女性村长。对于家庭调查，237个家庭的母亲（照顾者）和至少一个孩子之间的1和5岁increased.Results：大约20.7%的家庭被归类为粮食安全，8.4%为轻度粮食不安全，22.8%为中度粮食安全和48.1%为严重粮食不安全。旋转主成分因素分析得出两个主要因素：（i）食物质量不足;（ii）食物摄入量不足。这两个因素解释了总方差的69%。食物不安全量表和两个分量表具有良好的内部一致性（Cronbach’s alpha = 0.83-0.90）。粮食安全，作为衡量HFIAS，正相关与母亲的教育，丈夫的教育，家庭财富状况，是一个农业，而不是游牧部落，和动物源性食品消费，它是负相关的母亲年龄和家庭大小。结论：HFIAS测量工具显示的有效性和可靠性，在坦桑尼亚农村贫困家庭的家庭粮食不安全。
Objective: The purpose of the present study was to test the construct Validity, internal consistency and convergent validity of the Household Food Insecurity Access Scale (HFIAS) in measuring household food insecurity in rural Tanzania, and to determine socio-economic characteristics associated With household food insecurity.Design: Key informant interviews and a cross-sectional survey were conducted in February and March 2008.Setting: Rural Iringa, Tanzania.Subjects: Key informant interviews were conducted with twenty-one purposively selected male and female village leaders. For the household surveys, a sample of 237 households with mothers (caregivers) and at least one child between 1 and 5 years of age were included.Results: Approximately 20.7% of the households were categorized as food-secure, 8.4% as mildly food-insecure, 22.8% as moderately food-secure and 48.1% as severely food-insecure. Two main factors emerged from the rotated principal component factor analysis: (i) insufficient food quality; and (ii) insufficient food intake. Both factors explained 69% of the total variance. The full food insecurity scale and the two subscales had good internal consistency (Cronbach's alpha = 0.83-0.90). Food security, as measured by HFIAS, was positively associated with maternal education, husband's education, household wealth status, being of an agricultural rather than pastoral tribe , and animal-source food consumption; it was negatively associated with maternal age and household size.Conclusions: The HFIAS measurement instrument show's validity and reliability in measuring household food insecurity among poor households in rural Tanzania.
