Caffeine and Insomnia in People Living With HIV From the Miami Adult Studies on HIV (MASH) Cohort.

ABSTRACT: We explored the relationship between caffeine consumption, insomnia, and HIV disease progression (CD4+ T cell counts and HIV viral loads). Caffeine intake and insomnia levels were measured using the Modified Caffeine Consumption Questionnaire and the Pittsburgh Insomnia Rating Scale (PIRS) in 130 clinically stable participants who were living with HIV, taking antiretroviral therapy, and recruited from the Miami Adult Studies on HIV cohort. Linear regressions showed that caffeine consumption was significantly and adversely associated with distress score, quality-of-life score, and global PIRS score. Linear regression analyses also showed that global PIRS score was significantly associated with lower CD4+ T cell counts and higher HIV viral loads. Caffeine could have precipitated insomnia in susceptible people living with HIV, which could be detrimental to their disease progression states.

Project description:BackgroundFood insecurity is a social determinant of health associated with cognitive impairments in older adults and people living with HIV (PLWH). Few studies have examined this relation longitudinally, and no studies have explored how the frequency of food insecurity over time may impact cognitive impairment.ObjectiveThis study aimed to examine the impact of food insecurity on cognitive impairment over a 2-y follow-up period in a cohort of people living with and without HIV.MethodsThis was a 2-y longitudinal analysis of primarily economically disadvantaged, middle-aged, Black, and Hispanic participants from the Miami Adult Studies on HIV (MASH) cohort. Food insecurity was assessed with the USDA Household Food Security Module at baseline and 12- and 24-mo follow-ups. Food insecurity in all 3 assessments was considered persistent food insecurity. Cognitive impairment was assessed with the Mini-Mental State Examination. Statistical analyses consisted of logistic regressions.ResultsA total of 394 participants (247 HIV positive) with 2-y follow-up data were included in this analysis. At baseline, 104 (26.4%) were food-insecure and 58 (14.7%) had cognitive impairment. Very low food security was associated with cognitive impairment at baseline (OR: 3.23; 95% CI: 1.08, 9.65). PLWH not virally suppressed had higher risk for cognitive impairment compared with HIV-uninfected participants (OR: 2.87; 95% CI: 1.15, 7.18). Additionally, baseline food insecurity (OR: 2.28; 95% CI: 1.08, 4.81) and the frequency of food insecurity over time (OR: 1.50 per year; 95% CI: 1.08, 2.10), particularly persistent food insecurity (OR: 3.69; 95% CI: 1.15, 11.83), were associated with cognitive impairment at 2-y follow-up; the results were consistent after excluding cognitively impaired participants at baseline.ConclusionsFood insecurity is a significant risk factor for cognitive impairment, particularly among individuals who experience food insecurity frequently or persistently. Screening for food insecurity and interventions to secure access to sufficient, nutritious foods may help delay cognitive decline among socioeconomically disadvantaged individuals.

Project description:BackgroundIn Nepal, since 2004, 19,388 people living with HIV (PLHIV) have been enrolled on antiretroviral therapy (ART). The aim of this study was to measure mortality rate and to identify predictors of mortality in adult (≥15 years) PLHIV who initiated ART between 2004 and 2013 in five large ART centers of Nepal.MethodsThis retrospective cohort study of 3,799 (60.5% male) adult PLHIV uses secondary data collected from standard ART registers. Time from ART initiation (baseline) to death or censoring (loss to follow-up or December 31, 2013) was assessed. Mortality rates per 100 person-years were calculated. Kaplan-Meier models were used to estimate the probability of mortality over time. Predictors of mortality were determined using Cox-regression models.ResultsThe overall mortality rate was 6.98 (95% CI: 6.46-7.54) per 100 person-years, 4.11 (95% CI: 3.53-4.79) in females and 9.14 (95% CI: 8.36-9.99) in males. Mortality rates were higher in early months after ART initiation, particularly in the first three months. Baseline predictors of mortality were ART center, male gender (adjusted HR = 2.08, 95% CI: 1.69-2.57), residence outside the ART district (AHR = 1.45, 95% CI:1.19-1.76), World Health Organization clinical stage III (AHR = 1.67, 95% CI: 1.13-2.46) and IV (AHR = 2.21, 95% CI: 1.45-3.36), bedridden <50% time in the last month (AHR = 1.92, 95% CI: 1.52-2.41), bedridden >50% time in the last month (AHR = 3.82, 95% CI: 2.95-4.94), lower bodyweight/kg (AHR = 1.04, 95% CI: 1.03-1.05), CD4 count <150 cell/mm3 (AHR = 2.14, 95% CI: 1.05-4.34) and treatment not switched to second-line regimen (AHR = 3.05, 95% CI: 1.35-6.90).ConclusionsMortality rates were higher soon after ART initiation, particularly in males and gradually decreased over time. Poor baseline clinical characteristics were significantly associated with higher mortality. Increased ART coverage with decentralization of sites to lower levels including community dispensing, differentiated and improved service delivery and initiation of ART at a less advanced disease stage may reduce early mortality.
