Self-report health status measures are consistently associated with medical outcomes and are cost-effective. Studies using such measures find that those who live in rural areas or have limited access to support experience poorer health status and poorer outcomes. A survey addressing these issues was administered to 401 HIV-positive persons throughout Alabama. Hierarchical regression models examined the relation of housing stability, stress, substance use and other variables to physical (PCS) and mental (MCS) health status. The sample was 34% female and 66% African-American. Most were receiving antiretroviral medications, and nearly 20% were in unstable housing. Age showed a significant negative relationship to health status. CD4 cell count (p < 0.01) was positively associated with PCS; perceived general stress (p < 0.02) and housing stability (p < 0.04) were negatively associated. The model accounted for 14% of the variance in PCS (p < 0.001). For MCS, general stress (p < 0.001) was negatively associated and substance use tended towards a negative association (p < 0.075). Social support (p < 0.02) was positively associated with MCS. The model accounted for nearly 31% of the MCS variance (p < 0.001). Health status among HIV-positive persons may be improved by assessing and addressing social issues such as social isolation, life stressors and housing.
自我报告的健康状况指标一直与医疗结果相关,且具有成本效益。使用此类指标的研究发现,生活在农村地区或获得支持有限的人群健康状况较差,结果也较差。一项针对这些问题的调查在阿拉巴马州的401名艾滋病毒呈阳性者中进行。分层回归模型研究了住房稳定性、压力、物质使用和其他变量与身体(PCS)和心理(MCS)健康状况之间的关系。样本中34%为女性,66%为非裔美国人。大多数人正在接受抗逆转录病毒药物治疗,近20%的人居住在不稳定住房中。年龄与健康状况呈显著负相关。CD4细胞计数(p < 0.01)与PCS呈正相关;感知到的一般压力(p < 0.02)和住房稳定性(p < 0.04)呈负相关。该模型解释了PCS中14%的方差(p < 0.001)。对于MCS,一般压力(p < 0.001)呈负相关,物质使用倾向于呈负相关(p < 0.075)。社会支持(p < 0.02)与MCS呈正相关。该模型解释了近31%的MCS方差(p < 0.001)。通过评估和解决诸如社会隔离、生活压力源和住房等社会问题,艾滋病毒呈阳性者的健康状况可能会得到改善。
