本文介绍了相关性和回归分析，旨在评估家庭粮食不安全获取量表/患病率（HFIAS/HFIAP）（作为粮食获取的衡量标准），充足家庭粮食供应月数（MAHFP）（作为粮食获取稳定性的衡量标准）和（1）生活贫困指数（LPI）（作为基础设施获取的衡量标准）和（2）家庭收入之间的关系。该数据来自对11个南部非洲城市的6453户家庭的调查。研究结果表明，基础设施访问显着预测HFIAP和MAHFP分数。回归分析表明，在HFIAP中，无法获得现金收入，烹饪燃料，医疗保健，电力或水的家庭被归类为粮食不安全的可能性增加了11倍，并且在过去一年中，粮食供应不足12个月的可能性增加了8.5倍。家庭收入本身并不足以说明这些关系。相关性分析表明，所有的LPI分量表和家庭粮食获取之间有很强的关联。这些结果澄清了社会和物质基础设施对家庭粮食安全的不同影响，并表明城市环境的普遍条件可能比家庭收入本身更好地解释（和预测）城市家庭粮食安全。这项调查强调了城市规划和发展在减少城市贫困社区粮食不安全方面的核心作用。(C)2015爱思唯尔有限公司版权所有。
This paper presents correlation and regression analyses designed to assess the respective relationships between the Household Food Insecure Access Scale/Prevalence (HFIAS/HFIAP) (as a measure of food access), the Months of Adequate Household Food Provisioning (MAHFP) (as a measure of food access stability) and (1) the Lived Poverty Index (LPI) (as an infrastructure access measure) and (2) household income. The data is drawn from a survey of 6453 households from 11 Southern African cities. The findings indicate that infrastructure access significantly predicted HFIAP and MAHFP scores. The regression analyses demonstrated that households with inconsistent or no access to a cash income, cooking fuel, medical care, electricity, or water had 11 times greater odds of being categorized as food insecure in the HFIAP and 8.5 times greater odds of having less than 12 months of adequate food provisioning in the last year. Household income alone does not sufficiently account for these relationships. The correlation analyses demonstrate a strong association between all the LPI subscales and household food access. These results clarify the differential impact of social and physical infrastructure on household food security and demonstrate that the prevailing conditions of an urban environment may better explain (and predict) urban household food security than household income alone. This investigation emphasizes the central role that urban planning and development can play in reducing food insecurity in poor urban neighborhoods. (C) 2015 Elsevier Ltd. All rights reserved.
