Several cross-sectional studies have examined relationships between neighborhood characteristics and substance misuse. Using data from a sample of African-American adults relocating from U.S. public housing complexes, we examined relationships between changes in exposure to local socioeconomic conditions and substance misuse over time. We tested the hypothesis that adults who experienced greater post-relocation improvements in local economic conditions and social disorder would have a lower probability of recent substance misuse.
Data were drawn from administrative sources to describe the census tracts where participants lived before and after relocating. Data on individual-level characteristics, including binge drinking, illicit drug use, and substance dependence, were gathered via survey before and after the relocations. Multilevel models were used to test hypotheses.
Participants (N=172) experienced improvements in tract-level economic conditions and, to a lesser degree, in social disorder after moving. A one standard-deviation improvement in tract-level economic conditions was associated with a decrease in recent binge drinking from 34% to 20% (p=0.04) and with a decline in using illicit drugs weekly or more from 37% to 16% (p=0.02). A reduction in tract-level alcohol outlet density of >3.0 outlets per square mile predicted a reduction in binge drinking from 32% to 18% at p=0.05 significance level.
We observed relationships between improvements in tract-level conditions and declines in substance misuse, providing further support for the importance of the local environment in shaping substance misuse. These findings have important implications for public housing policies and future research.
多项横断面研究已经检验了邻里特征与物质滥用之间的关系。本研究利用从美国公共住房搬迁而来的非裔美国成年人样本数据,考察了个体在一段时间内接触当地社会经济条件的变化与物质滥用之间的关系。我们检验了这样一个假设,即经历了更多的地方经济条件改善和社会混乱的成年人,其近期物质滥用的可能性更低。
本研究从行政数据中提取参与者搬迁前后居住的普查区信息,用以描述其居住环境。个人层面的特征数据,包括酗酒、非法药物使用和物质依赖,通过搬迁前后的调查收集。使用多水平模型检验假设。
参与者(N=172)在搬迁后经历了所在普查区经济条件的改善,社会混乱程度也有所改善。普查区经济条件每提高一个标准差,近期酗酒的比例从 34%下降到 20%(p=0.04),每周或更频繁使用非法药物的比例从 37%下降到 16%(p=0.02)。普查区每平方英里的酒精销售点密度减少超过 3.0 个,预示着酗酒率从 32%下降到 18%(p=0.05)。
我们观察到普查区条件改善与物质滥用减少之间的关系,进一步支持了当地环境对物质滥用的重要性。这些发现对公共住房政策和未来的研究具有重要意义。
