RESUMEN

OBJECTIVE: To investigate the role of early antiretroviral therapy (ART) on growth trajectories of infants with human immunodeficiency virus (IHIV) in the first year of life. STUDY DESIGN: As part of a clinical trial of early ART in Johannesburg, South Africa (2015-2018), 116 IHIV diagnosed within 48 hours of birth were started on ART as soon as possible, and 80 uninfected infants born to mothers living with HIV (IHEU) were enrolled. Both groups were followed prospectively from birth through 48 weeks and growth parameters collected. The groups were compared and risk factors for poor growth investigated, in the full cohort and among IHIV separately. RESULTS: IHIV had lower mean weight-for-age Z-scores (WAZ) than IHEU at 4 and 8 weeks (-1.17 [SE:0.14] vs -0.72 [0.14], P = .035 and -1.23 [0.15] vs -0.67 [0.14], P = .012). Although there was some closing of the gap over time, means remained lower in IHIV through 48 weeks. In length-for-age Z-scores (LAZ), differences widened over time and IHIV had lower Z-scores by 48 weeks (-1.41 [0.15] vs -0.80 [0.18], P = .011). Deficits in WAZ and LAZ in IHIV vs IHEU were most marked among girls. IHIV with pre-ART viral load ≥1000 copies/ml had significantly lower weight-for-length and mid-upper arm circumference Z-scores across all time points through 48 weeks. CONCLUSIONS: IHIV on early ART had deficits in WAZ over the first 8 weeks of life and lower LAZ at 48 weeks than IHEU. Among IHIV, higher pre-ART viral load was associated with worse anthropometric indicators through 48 weeks.

RESUMEN

Disclosure to children living with HIV (CLHIV) about their own status is associated with positive outcomes such as treatment adherence, but prior cross-sectional studies in sub-Saharan Africa report disclosure rates of <50%. This study aims to assess pediatric disclosure over time. 548 CLHIV were followed from 2/2013-4/2018 in Johannesburg, South Africa. Cumulative incidence of disclosure was calculated with Kaplan-Meier analysis, and disclosure characteristics assessed with a Cox model. By end of follow-up, cumulative disclosure was 70.3% (95% confidence interval: 60.0-79.9). Median age at disclosure was 9 years (range: 3-13). Baseline predictors of disclosure included older child age and the child having a history of going hungry. Prior to disclosure, 98.0% of caregivers who disclosed had conversed with their child about their illness or an HIV-related topic, or their child had asked about HIV, versus 88.6% of caregivers who never disclosed. While many children did not receive disclosure during this relatively large, longitudinal study of South African CLHIV, caregivers who had not yet disclosed may have been preparing to do so by discussing their child's health or HIV generally with their child. This highlights the need for clinicians to consistently support caregivers throughout the incremental disclosure process.

RESUMEN

BACKGROUND: Early-life metabolic derangements in HIV-exposed uninfected (HEU) infants have been reported. METHODS: Pregnant women with HIV and HIV-uninfected pregnant women were enrolled with their newborns in a US cohort from 2011 to 2015. We measured cord insulin, C-peptide, and metabolic cytokines of HEU and HIV-unexposed uninfected (HUU) newborns using ELISA and metabolites, lipid subspecies, and eicosanoids via liquid chromatography/mass spectrometry. Linear regression was employed to assess the association of intrauterine HIV/ART with insulin and C-peptide. Graphical lasso regression was used to identify differences between metabolite/lipid subspecies networks associated with C-peptide. RESULTS: Of 118 infants, 56 were HEU, ART exposed. In adjusted analyses, mean cord insulin (ß = 0.295, p = 0.03) and C-peptide (ß = 0.522, p < 0.01) were significantly higher in HEU vs. HUU newborns. HEU neonates exhibited primarily positive associations between complex lipids and C-peptide, indicative of fuel storage, and augmented associations between cord eicosanoids and cytokines. HUU neonates exhibited negative associations with lipids and C-peptide indicative of increased fuel utilization. CONCLUSION: Higher cord insulin and C-peptide in HEU vs. HUU newborns as well as differences in cord metabolites, metabolic-related cytokines, and eicosanoids may reflect a propensity for fuel storage and an inflammatory milieu suggestive of fetal metabolic changes associated with in utero HIV/ART exposure. IMPACT: There is a paucity of studies assessing cord blood and neonatal metabolic health in HIV-exposed uninfected (HEU) newborns, an increasing population worldwide. Compared to HIV-unexposed uninfected (HUU) newborns, HEU newborns exhibit alterations in fuel homeostasis and an inflammatory milieu associated with in utero HIV/antiretroviral therapy (ART) exposure. The long-term implications of these neonatal findings are as yet unknown, but merit continued evaluation as this important and growing population ages into adulthood.

RESUMEN

HIV viral load (VL) monitoring can reinforce antiretroviral therapy (ART) adherence. Standard VL testing requires high laboratory capacity and coordination between clinic and laboratory which can delay results. A randomized trial comparing point-of-care (POC) VL testing to standard VL testing among 150 adolescents and young adults, ages 10-24 years, living with HIV in Haiti determined if POC VL testing could return faster results and improve ART adherence and viral suppression. Participants received a POC VL test with same-day result (POC arm) or a standard VL test with result given 1 month later (SOC arm). POC arm participants were more likely to receive a test result within 6 weeks than SOC arm participants (94.7% vs. 80.1%; p1000 copies/ml and low self-reported ART adherence was stronger in the POC arm (OR: 6.57; 95%CI: 2.12-25.21) than the SOC arm (OR: 2.62; 95%CI: 0.97-7.44) suggesting more accurate self-report in the POC arm. POC VL testing was effectively implemented in this low-resource setting with faster results and is a pragmatic intervention that may enable clinicians to identify those with high VL to provide enhanced counseling or regimen changes sooner.Trial registration: ClinicalTrials.gov identifier: NCT03288246.

RESUMEN

BACKGROUND: We describe tuberculosis (TB) disease among antiretroviral treatment (ART) eligible children living with HIV (CLHIV) in South Africa to highlight TB prevention opportunities. METHODS: In our secondary analysis among 0- to 12-year-old ART-eligible CLHIV in five Eastern Cape Province health facilities from 2012 to 2015, prevalent TB occurred 90 days before or after enrollment; incident TB occurred >90 days after enrollment. Characteristics associated with TB were assessed using logistic and Cox proportional hazards regression with generalized estimating equations. RESULTS: Of 397 enrolled children, 114 (28.7%) had prevalent TB. Higher-income proxy [adjusted odds ratio (aOR) 1.8 [95% confidence interval (CI) 1.3-2.6] for the highest, 1.6 (95% CI 1.6-1.7) for intermediate]; CD4+ cell count <350 cells/µl [aOR 1.6 (95% CI 1.1-2.2)]; and malnutrition [aOR 1.6 (95% CI 1.1-2.6)] were associated with prevalent TB. Incident TB was 5.2 per 100 person-years and was associated with delayed ART initiation [hazard ratio (HR) 4.7 (95% CI 2.3-9.4)], malnutrition [HR 1.8 (95% CI 1.1-2.7)] and absence of cotrimoxazole [HR 2.3 (95% CI 1.0-4.9)]. Among 362 children with data, 8.6% received TB preventive treatment. CONCLUSIONS: Among these CLHIV, prevalent and incident TB were common. Early ART, cotrimoxazole and addressing malnutrition may prevent TB in these children.


BACKGROUND: We describe tuberculosis (TB) in children living with HIV (CLHIV) eligible for HIV treatment in South Africa to highlight opportunities to prevent TB. METHODS: We analyzed additional data from our original study of CLHIV who were 0­12 years old and due to start HIV treatment in five health facilities in Eastern Cape Province from 2012 to 2015 and assessed characteristics associated with existing and new TB. RESULTS: Of 397 enrolled children, 114 (28.7%) had existing TB. Children with a higher measure of household income had higher odds of existing TB. CD4+ cell count <350 cells/µl and malnutrition were also associated with existing TB. There were 5.2 new cases of TB for every 100 child-years. New TB was 4.7 times more likely for children with delayed HIV treatment start, 1.8 times more likely for children with malnutrition and 2.3 times more likely for children who did not get cotrimoxazole. Among 362 children with data, 8.6% received treatment to prevent TB. CONCLUSIONS: Among these CLHIV, existing and new TB were common. Early HIV treatment, cotrimoxazole and addressing malnutrition may prevent TB in these children.

RESUMEN

BACKGROUND: Accelerated epigenetic aging using DNA methylation (DNAm)-based biomarkers has been reported in people with human immunodeficiency virus (HIV, PWH), but limited data are available among African Americans (AA), women, and older PWH. METHODS: DNAm was measured using Illumina EPIC Arrays for 107 (69 PWH and 38 HIV-seronegative controls) AA adults ≥60 years in New York City. Six DNAm-based biomarkers of aging were estimated: (1) epigenetic age acceleration (EAA), (2) extrinsic epigenetic age acceleration (EEAA), (3) intrinsic epigenetic age acceleration (IEAA), (4) GrimAge, (5) PhenoAge, and (6) DNAm-estimated telomere length (DNAm-TL). The National Institutes of Health (NIH) Toolbox Cognition Battery (domains: executive function, attention, working memory, processing speed, and language) and Montreal Cognitive Assessment (MoCA) were administered. Participants were assessed for frailty by the Fried criteria. RESULTS: The PWH and control groups did not differ by sex, chronological age, or ethnicity. In total, 83% of PWH had a viral load <50 copies/mL, and 94% had a recent CD4 ≥200 cells/µL. The PWH group had a higher EAA, EEAA, GrimAge, and PhenoAge, and a lower DNAm-TL compared to the controls. IEAA was not different between groups. For PWH, there were significant negative correlations between IEAA and executive function, attention, and working memory and PhenoAge and attention. No associations between biomarkers and frailty were detected. CONCLUSIONS: Evidence of epigenetic age acceleration was observed in AA older PWH using DNAm-based biomarkers of aging. There was no evidence of age acceleration independent of cell type National Institutes of Health composition (IEAA) associated with HIV, but this measure was associated with decreased cognitive function among PWH.

RESUMEN

BACKGROUND: Adolescents aged 10-19 years living with human immunodeficiency virus (HIV) (ALHIV), both perinatally infected adolescents (APHIV) and behaviorally infected adolescents (ABHIV), are a growing population with distinct care needs. We characterized the epidemiology of HIV in adolescents included in Population-based HIV Impact Assessments (2015-2017) in Zimbabwe, Malawi, Zambia, Eswatini, and Lesotho. METHODS: Adolescents were tested for HIV using national rapid testing algorithms. Viral load (VL) suppression (VLS) was defined as VL <1000 copies/mL, and undetectable VL (UVL) as VL <50 copies/mL. Recent infection (within 6 months) was measured using a limiting antigen avidity assay, excluding adolescents with VLS or with detectable antiretrovirals (ARVs) in blood. To determine the most likely mode of infection, we used a risk algorithm incorporating recency, maternal HIV and vital status, history of sexual activity, and age at diagnosis. RESULTS: HIV prevalence ranged from 1.6% in Zambia to 4.8% in Eswatini. Of 707 ALHIV, 60.9% (95% confidence interval, 55.3%-66.6%) had HIV previously diagnosed, and 47.1% (41.9%-52.3%) had VLS. Our algorithm estimated that 72.6% of ALHIV (485 of 707) were APHIV, with HIV diagnosed previously in 69.5% of APHIV and 39.4% of ABHIV, and with 65.3% of APHIV and 33.5% of ABHIV receiving ARV treatment. Only 67.2% of APHIV and 60.5% of ABHIV receiving ARVs had UVL. CONCLUSIONS: These findings suggest that two-thirds of ALHIV were perinatally infected, with many unaware of their status. The low prevalence of VLS and UVL in those receiving treatment raises concerns around treatment effectiveness. Expansion of opportunities for HIV diagnoses and the optimization of treatment are imperative.

RESUMEN

OBJECTIVES: Children with HIV (CHIV) have lifetime exposure to antiretrovirals (ART); therefore, optimizing their regimens to have the least impact on fat redistribution is a priority. METHODS: This is a cross-sectional study of 219 perinatally infected CHIV and 219 HIV-uninfected controls from similar socioeconomic backgrounds in Johannesburg, South Africa. We compared total body and regional fat distribution in CHIV on suppressive ART regimens with controls and, among CHIV, between ritonavir-boosted lopinavir (LPV/r)-based and efavirenz (EFV)-based regimens. RESULTS: The mean age of the 219 uninfected children (45% girls) and the 219 CHIV (48% girls) was 7.0 and 6.4 years, respectively. CHIV had lower adjusted total body fat (P = 0.005) and lower percentage fat at the trunk (P = 0.020), arms (P = 0.001), and legs (P < 0.001) than uninfected children. CHIV on LPV/r had similar body composition as those on EFV, except for arm fat mass (P = 0.030). When stratified by sex, girls with HIV on LPV/r had lower adjusted total (P = 0.007), trunk (P = 0.002), arms (P = 0.008), legs (P = 0.048) fat mass; trunk-to-total body fat (P = 0.044); and higher legs-to-total body fat (P = 0.011) than those on EFV. CONCLUSIONS: South African CHIV receiving ART had lower global and partial fat mass and percentage fat than healthy controls. In girls with HIV with sustained virologic suppression on ART, switching from LPV/r to EFV could attenuate fat mass loss, indicating that EFV-based regimen may be a better option in this group of individuals.

RESUMEN

PURPOSE OF REVIEW: In the era of modern bone-friendly antiretroviral therapy (ART) regimens for people living with HIV (PLWH), this review discusses the research gaps and management concerns that remain for individuals who have already been exposed to ART with negative effects on bone metabolism, especially children and adolescents who have not acquired peak bone mass, and older adults who have additional risk factors for fracture. RECENT FINDINGS: Data now support the use of avoidance of TDF and use of bone-friendly regimens that include integrase strand transfer inhibitors in PLWH with increased risk of fracture for either ART initiation or switch. Despite significant advances in our understanding of ART choice for PLWH with regard to bone health, additional diagnostic tests to determine fracture risk and management strategies beyond ART choice are necessary, especially in vulnerable PLWH populations, such as children and adolescents and older adults.

RESUMEN

Adolescents and youth living with HIV have poorer antiretroviral treatment (ART) adherence and viral suppression outcomes than all other age groups. Effective interventions promoting adherence are urgently needed. We reviewed and synthesized recent literature on interventions to improve ART adherence among this vulnerable population. We focus on studies conducted in low- and middle-income countries (LMIC) where the adolescent and youth HIV burden is greatest. Articles published between September 2015 and January 2019 were identified through PubMed. Inclusion criteria were: [1] included participants ages 10-24 years; [2] assessed the efficacy of an intervention to improve ART adherence; [3] reported an ART adherence measurement or viral load; [4] conducted in a LMIC. Articles were reviewed for study population characteristics, intervention type, study design, outcomes measured, and intervention effect. Strength of each study's evidence was evaluated according to an adapted World Health Organization GRADE system. Articles meeting all inclusion criteria except being conducted in an LMIC were reviewed for results and potential transportability to a LMIC setting. Of 108 articles identified, 7 met criteria for inclusion. Three evaluated patient-level interventions and four evaluated health services interventions. Of the patient-level interventions, two were experimental designs and one was a retrospective cohort study. None of these interventions improved ART adherence or viral suppression. Of the four health services interventions, two targeted stable patients and reduced the amount of time spent in the clinic or grouped patients together for bi-monthly meetings, and two targeted patients newly diagnosed with HIV or not yet deemed clinically stable and augmented clinical care with home-based case-management. The two studies targeting stable patients used retrospective cohort designs and found that adolescents and youth were less likely to maintain viral suppression than children or adults. The two studies targeting patients not yet deemed clinically stable included one experimental and one retrospective cohort design and showed improved ART adherence and viral suppression outcomes. ART adherence and viral suppression outcomes remain a major challenge among adolescents and youth. Intensive home-based case management models of care hold promise for improving outcomes in this population and warrant further research.

RESUMEN

Little is known about how growing up with HIV impacts educational outcomes in sub-Saharan African children. We evaluated if South African children living with HIV (CLWH) were in the appropriate school grade-for-age compared to uninfected control children. We observed higher rates of not being in the correct grade-for-age in CLWH compared with controls (OR 3.32, 95% CI: 2.07-5.34), adjusted for study site, sex, whether the child's biological father was alive, and caregiver education. Initiation of ART before 6 months of age reduced but did not eliminate this association. Whether these associations are due to biological factors or other social and environmental determinants, and how best to support CLWH to achieve educational goals, warrants further investigation.

RESUMEN

Perinatal HIV infection is associated with delayed neurocognitive development, but less is known about children perinatally HIV-exposed but uninfected (CHEU). We compared cognitive and language outcomes in 4-6-year old CHEU versus children HIV-unexposed and uninfected (CHUU) and children living with HIV (CLHIV). We enrolled 1,581 children (77% of the child population) in five communities in KwaZulu-Natal, South Africa. Children completed: Grover-Counter Scale of cognitive development, sub-scales of the Kaufman Assessment Battery for Children, Reynell Developmental Language Scales. HIV status of children and primary caregivers was determined by repeated rapid tests or report of prior testing. We conducted a cross-sectional multivariable linear regression on 922 dyads with complete data (257 CHEU, 627 CHUU, 38 CLHIV). On all outcome measures, CHEU and CHUU groups had comparable scores; CLHIV scored significantly lower. Emerging global progress toward the elimination of vertical HIV transmission may not only reduce mortality, but also positively impact child development.

RESUMEN

We evaluated bone quality among South African children with HIV over a 2-year period by quantitative ultrasound (QUS). Children with HIV have persistently lower bone quality compared with controls reflecting increased porosity, reduced strength, and possibly an increased short- and long-term risk of fracture.

RESUMEN

How and when to disclose a positive HIV diagnosis to an infected child is a complex challenge for caregivers and healthcare workers. With the introduction of antiretroviral therapy, pediatric HIV infection has transitioned from a fatal disease to a lifelong chronic illness, thus increasing the need to address the disclosure process. As HIV-infected children mature, begin to take part in management of their own health care, and potentially initiate HIV-risk behaviors, understanding the nature of their infection becomes essential. Guidelines recommend developmentally appropriate incremental disclosure, and emphasize full disclosure to school-age children. However, studies from Sub-Saharan Africa report that disclosure to HIV-infected children is often delayed. Between 2013 and 2014, 553 perinatally HIV-infected children aged 4-9 years were enrolled into a cohort study in Johannesburg, South Africa. We assessed the extent of disclosure among these children and evaluated characteristics associated with disclosure. No children aged 4 years had been told their status, while 4% of those aged 5 years, and 8%, 13%, 16%, and 15% of those aged 6, 7, 8, and 9 years, respectively, had been told their status. Age was the strongest predictor of full disclosure (odds ratio 1.6 per year, p = .001). An adult living in the household who was unaware of the child's status was associated with a reduced probability of disclosure, and knowing that someone at the child's school was aware of child's status was associated with an increased probability of disclosure. Among caregivers who had not disclosed, 42% reported ever discussing illness in general with the child, and 17% reported ongoing conversations about illness or HIV. In conclusion, a small minority of school-age children had received full disclosure. Caregivers and healthcare workers require additional support to address disclosure. A broader public health strategy integrating the disclosure process into pediatric HIV treatment programs is recommended.

RESUMEN

OBJECTIVES: The World Health Organization recommends that human immunodeficiency virus (HIV)-infected children increase energy intake and maintain a balanced macronutrient distribution for optimal growth and nutrition. Few studies have evaluated dietary intake of HIV-infected children in resource-limited settings. METHODS: We conducted a cross-sectional analysis of the dietary intake of 220 perinatally HIV-infected children and 220 HIV-uninfected controls ages 5 to 9 years in Johannesburg, South Africa. A standardized 24-hour recall questionnaire and software developed specifically for the South African population were used to estimate intake of energy, macronutrients, and micronutrients. Intake was categorized based on recommendations by the World Health Organization and Acceptable Macronutrient Distribution Ranges established by the IOM. RESULTS: The overall mean age was 6.7 years and 51.8% were boys. Total energy intake was higher in HIV-infected than HIV-uninfected children (1341 vs 1196 kcal/day, P = 0.002), but proportions below the recommended energy requirement were similar in the 2 groups (82.5% vs 85.2%, P = 0.45). Overall, 51.8% of the macronutrient energy intake was from carbohydrates, 13.2% from protein, and 30.8% from fat. The HIV-infected group had a higher percentage of their energy intake from carbohydrates and lower percentage from protein compared with the HIV-uninfected group. Intakes of folate, vitamin A, vitamin D, calcium, iodine, and selenium were suboptimal for both groups. CONCLUSIONS: Our findings suggest that the typical diet of HIV-infected children and uninfected children in Johannesburg, South Africa, does not meet energy or micronutrient requirements. There appear to be opportunities for interventions to improve dietary intake for both groups.

BACKGROUND: Given the high prevalence of mental health (MH) and substance abuse problems in low-to-middle income countries, the scarcity of MH professionals and the negative impact of psychiatric disorders on caregivers of young children, there is significant need for brief evidence-based screening tools for lay counselors to assist with MH assessment. This study aimed to validate a brief screening tool to assess psychiatric and substance use disorders, the Client Diagnostic Questionnaire (CDQ), in South Africa (SA). METHODS: Data are from a longitudinal study of health and psychosocial needs in preschool children in SA. Participants included 322 Zulu-speaking, female caregivers. Following procedures of the US CDQ validation study, lay counselors interviewed participants using the translated Zulu CDQ. Subsequently a psychologist conducted a full psychiatric assessment guided by the CDQ questions. Analyses examined sensitivity, specificity and overall accuracy, comparing lay counselor and psychologist assessment. RESULTS: Sensitivity (73%), specificity (81%) and overall accuracy (79%) were good for the variable indicating presence of 'any diagnosis.' Among those cases identified by the psychologist as having any psychiatric diagnosis, over 70% were correctly identified by lay counselors using the CDQ (i.e., positive predictive value was greater than 70%). The false positive rate was relatively low (19%). Specificity for 'any disorder' (including substance use) and 'any psychiatric disorder' were 81% and 79%. CONCLUSIONS: The isiZulu CDQ is a sensitive and valid MH diagnostic screener that can be used by lay counselors with limited MH training to identify those in need of treatment and target extremely scarce MH professionals.

KEY PRACTITIONER MESSAGES: South Africa (SA), a country heavily impacted by poverty, HIV and the legacy of Apartheid, has a high prevalence of mental health (MH) and substance abuse problems. In SA and other low-and-middle-income-countries (LMIC) there is a dearth of MH professionals. This study examined use and validity of the Client Diagnostic Questionnaire (CDQ), a brief diagnostic MH screening tool designed for use by lay counselors in HIV-affected populations. Comparing lay counsellor diagnoses on the CDQ to clinician assessment, sensitivity, specificity and overall accuracy were good at the level of 'any diagnosis.' The CDQ can be used effectively in SA and other LMIC with limited MH services to enable appropriate and efficient referral of individuals in primary care settings, supporting caregivers and the children in their care.

RESUMEN

OBJECTIVE: To describe physical activity in South African children with and without HIV. STUDY DESIGN: Study measurements were obtained in 218 children with perinatal HIV and 180 children without HIV aged 5-9 years in a study conducted in Johannesburg, South Africa. Weight-for-age z-score, height-for-age z-score, frequency and duration of moderate and vigorous physical activity, and sedentary behaviors were obtained. These measurements were compared between children with and without HIV. RESULTS: Weight-for-age z-score and height-for-age z-score were significantly lower for children with HIV compared with those without HIV. Among children who attended school, fewer children with HIV than children without HIV participated in physical education (41% vs 64%; P = .0003) and organized after-school sports (38% vs 64%; P < .001). The proportion of children in both groups meeting World Health Organization recommendations for physical activity was similar (84% overall); however, girls with HIV spent less time in vigorous physical activity than girls without HIV (420 vs 780 minutes/week; P = .001). This difference remained significant even when girls with a medical condition with the potential to limit physical activity were excluded, and after adjusting for age. Time spent in sedentary behaviors did not differ significantly between the two groups. CONCLUSION: Although children with HIV with well-controlled disease after initiating antiretroviral therapy early in life achieve high levels of physical activity, vigorous physical activity is lower in girls with HIV than in healthy controls. This finding may reflect lower participation in school-based physical education and organized after-school physical activity.

RESUMEN

Background and Objectives Alcohol abuse, a significant health problem in South Africa, affects the ability of adults to care for children. Little is known regarding risky alcohol use among child caregivers there. A large population-based study examined the prevalence of, and factors associated with, risky drinking among caregivers of young children in KwaZulu-Natal, South Africa comparing the use of the Alcohol Use Disorders Identification Test (AUDIT) and the AUDIT-C screens for hazardous or harmful drinking (referred to here as risky drinking). Methods 83 % of child caregivers from five tribal areas were interviewed using the 10-question AUDIT to screen for risky drinking. The AUDIT-C screen, a subset of AUDIT questions, targets alcohol consumption and binge drinking. Factors associated with risky drinking were investigated using logistic regression. Results 1434 caregivers participated, 98 % female. Sixteen percent reported ever drinking alcohol. Based on AUDIT criteria for risky drinking, 13 % of the sample scored as moderate drinkers, 2 % as hazardous users, and 1 % as harmful or dependent users (identifying 3 % as risky drinkers). Using AUDIT-C criteria to identify risky drinking significantly increased the proportion of caregivers identified as risky drinkers to 9 %. In multivariate analyses, factors associated with risky drinking were similar in both screens: partner violence, smoking, HIV-infection, caring for a child with disabilities. Conclusions for Practice Since the AUDIT-C identified risky alcohol use not otherwise detected with the full AUDIT, and since resources for screening in health care settings is limited, the AUDIT-C may be a more appropriate screen in populations where binge drinking is common.

RESUMEN

Little research exists regarding the use of social networking sites, like Facebook, for improving patient well-being. The aim of this study was to evaluate a private Facebook group established for members of an HIV clinic's young adult program. This study employed directed content analysis to examine the types and frequencies of interactions observable in the 3,838 posts and comments that appeared on the Facebook group page between March 1, 2011 and July 1, 2012. Analysis revealed that a large percentage (41.7 %) of the content was classified as "administrative/engagement in group" and functioned to enhance the operations of the program as a whole. Additionally, positive interactions were frequently observed, especially socializing (24.8 %), banter (20.2 %), and offers of social support (15.1 %). Emotional support was the most frequent type of support requested, while esteem support was the most commonly provided form of support. The results of this study demonstrate that a Facebook group can be a means of providing patients with social support and positive social interaction and can improve services for young adults with HIV.
