Retention in care in aging adults with a dual diagnosis of HIV infection and type 2 diabetes mellitus: a longitudinal retrospective cross-sectional study

摘要

This study aimed to investigate the measures of retention in care (RIC) in persons living with HIV (PLWH) and type 2 diabetes mellitus (T2DM) by age group (younger vs. older adults). This was a longitudinal retrospective cross-sectional study that used secondary data from the Center for AIDS Research Network of Integrated Clinical Systems (CNICS). We examined RIC in 798 adult PLWH?+?T2DM who visited a CNICS clinic at least once in 2015. Six measures of RIC were examined: missed visits [measured as a continuous variable (total number of missed visits) and dichotomous variable (0?=?never missed, 1?=?missed)], visit adherence, 6-month visit gap, 4-month visit constancy, and the Health and Resources Services Administration HIV/AIDS Bureau’s RIC measure. We calculated Spearman correlation coefficients and conducted logistic regression and multi-group path analysis. Most RIC measures were significantly correlated (p??0.05) with one another; only 4-month visit constancy was not correlated with other measures. Except for the number of missed visits in older adult PLWH?+?T2DM, we found no significant relationships between RIC measures and CD4 cell count using logistic regression. However, multi-group path analysis demonstrated significant positive relationships between most RIC measures and CD4 cell count in both age groups. In younger adults living with HIV (YALWH)?+?T2DM, HbA1c level, but not CD4 count, was significantly associated with most RIC measures. RIC is related to disease control (CD4 cell count and HbA1c level) in PLWH?+?T2DM and notably, HbA1c level was only significantly affected in YALWH?+?T2DM. A future study is needed to find more accurate reasons for the fact that only HbA1c level had significant relationships in YALWH?+?T2DM. The findings from this study provide guidance in measuring RIC in PLWH who have comorbidities.
