Research examining the association of residence in racially segregated neighborhoods with physical and mental health outcomes among blacks is mixed. Research elucidating the relationship between segregation and hypertension has been limited. This study examines the association between segregation and hypertension among US- and foreign-born blacks in New York City (NYC).
Individual-level data from the NYC Community Health Survey (n = 4,499) were linked to neighborhood-level data from the US Census and Infoshare Online. Prevalence ratios (PRs) for the association between segregation and self-reported hypertension among US- and foreign-born blacks were estimated.
After adjusting for individual- and neighborhood-level covariates, segregation was not associated with hypertension among US-born blacks or foreign-born blacks under 65 years of age. Older foreign-born blacks in highly segregated areas had a 46% lower probability (PR = 0.54; 95% confidence interval, 0.40-0.72) of reporting hypertension than older foreign-born blacks residing in low segregation areas.
In this NYC-based sample, no association between segregation and hypertension was observed among US-born or younger foreign-born blacks; however, our results suggest possible benefits of segregation for older foreign-born blacks. Further studies should determine whether this association is observed in other cities and identify factors that may mitigate against the adverse effects of segregation.
研究考察了居住在种族隔离社区与黑人群体身心健康结果之间的关联,结果不一。关于隔离与高血压之间关系的研究有限。本研究检验了纽约市(NYC)美国和外国出生黑人的隔离与高血压之间的关联。
纽约市社区健康调查(n=4499)的个体水平数据与美国人口普查和 Infoshare Online 的社区水平数据相链接。通过调整个体和社区水平的协变量,来估计隔离与美国和外国出生黑人自我报告的高血压之间的关联。
在调整了个体和社区水平的协变量后,在年龄较大的外国出生黑人中,居住在高度隔离地区的人患高血压的可能性比居住在低隔离地区的人低 46%(PR=0.54;95%置信区间,0.40-0.72)。居住在高度隔离地区的年龄较大的外国出生黑人患高血压的可能性比居住在低隔离地区的人低 46%(PR=0.54;95%置信区间,0.40-0.72)。
在这个基于纽约市的样本中,没有观察到隔离与美国出生或较年轻的外国出生黑人的高血压之间存在关联;然而,我们的结果表明,隔离可能对年龄较大的外国出生黑人有益。进一步的研究应确定这种关联是否在其他城市中存在,并确定可能减轻隔离不利影响的因素。
