Investments in historically oppressed neighborhoods through food retail, housing, and commercial development are hypothesized to improve residents' health, nutrition, and perceptions of their neighborhood as a place to live. Although place-based development (e.g., housing, retail, business assistance) is happening in many communities, there is little evidence of the long-term correlates of multiple investments such as health and nutrition among residents.
A quasi-experimental longitudinal study was conducted using a cohort of randomly sampled households in two low-income, predominantly African American neighborhoods in Pittsburgh, PA, with surveys assessing residents' food insecurity, perception of their neighborhood as a place to live, perception of access to healthy foods, and dietary outcomes in 2011 and seven years later (2018), with an interim assessment in 2014. Analyses conducted in 2022 compared changes among residents of one neighborhood which had 2.6 times the investments over a 7-year period with changes among residents of a socio-demographically similar neighborhood that received fewer investments.
It was found that residents in the neighborhood receiving substantial investments demonstrated statistically significant improvements in neighborhood satisfaction (12.6% improvement compared with a 2.2% decrease) and perceived access to healthy food (52% improvement compared with 18.2% improvement), and marginally significant change in food security (14% compared with 4.8% improvement) compared with residents in the neighborhood receiving fewer investments.
Multiple place-based investments in neighborhoods can potentially induce positive change for residents in health and nutrition outcomes.
通过食品零售、住房和商业发展投资于历史上受压迫的社区,据推测可以改善居民的健康、营养状况,并增强他们对居住社区的看法。尽管许多社区都在进行基于地点的发展(例如住房、零售、商业援助),但对于居民的健康和营养等多种投资的长期相关性几乎没有证据。
本研究采用了匹兹堡两个低收入、以非裔美国人为主的社区的随机抽样家庭队列进行准实验性纵向研究,调查评估了居民的粮食不安全状况、对居住社区的看法、获得健康食品的看法以及 2011 年和 7 年后(2018 年)的饮食结果,并在 2014 年进行了中期评估。2022 年进行的分析比较了一个社区的居民变化情况,该社区在 7 年内投资增加了 2.6 倍,而一个社会人口统计学上相似的社区投资较少。
研究发现,接受大量投资的社区的居民在社区满意度(12.6%的改善,而另一个社区则下降了 2.2%)和感知到的获得健康食品的机会(52%的改善,而另一个社区则改善了 18.2%)方面有显著改善,而在粮食安全方面则有略微显著的变化(14%的改善,而另一个社区则改善了 4.8%)。
社区的多种基于地点的投资可能会对居民的健康和营养结果产生积极影响。
