Predictors of early initiation of breastfeeding among Zimbabwean women: secondary analysis of ZDHS 2015.

BACKGROUND: The World Health Organization recommends initiation of breastfeeding within the first hour of delivery. Early initiation is beneficial for both mother and baby. Previous Zimbabwe Demographic and Health Surveys (ZDHS) have shown reduction in early initiation of breast feeding from 68% (2005/06) to 58% (2015). This study sought to investigate factors associated with early initiation of breast feeding among women aged 15-49 years in Zimbabwe. METHODOLOGY: Secondary analysis of ZDHS 2015 data was done to investigate the association between early initiation of breast feeding and maternal, provider and neonatal factors using multivariate logistic regression (n = 2192). RESULTS: The majority of the study sample (78%) reported having practised early initiation of breastfeeding during their most recent delivery (preceding 24 months).Children who were put on skin to skin contact (AOR = 1.51, 95% CI 1.13-2.02) and those delivered by skilled attendants (AOR = 4.36, 95% CI 1.07-17.77) had greater odds of early initiation compared to those who were not. Other factors associated with early initiation were multiparity (AOR 1.82 95% CI 1.33-2.49) and rural residence (AOR 2.10 95% 1.12-3.93). However, having an abnormal birth weight, i.e. low birth weight (AOR 0.60 95% CI 0.36-0.99) and macrosomia (AOR = 0.42, CI 0.22-0.79) as well as delivery by caesarean section (AOR 0.1195% CI 0.06-0.19) were associated with reduced odds of early initiation. CONCLUSION: Early initiation of breast feeding in Zimbabwe is mainly associated with residing in the rural areas and multiparity. The 78% rate of early initiation of breastfeeding was contrary to the 58% reported in the ZDHS findings. Interventions targeting an improvement in early initiation of breastfeeding must aim at women who deliver by caesarean section, women with babies of abnormal birth weight, primi-parous women and women residing in rural areas.

Loss to follow-up among children and adolescents growing up with HIV infection: age really matters.

INTRODUCTION: Globally, increasing numbers of HIV-infected children are reaching adolescence due to antiretroviral therapy (ART). We investigated rates of loss-to-follow-up (LTFU) from HIV care services among children as they transition from childhood through adolescence. METHODS: Individuals aged 5-19 years initiated on ART in a public-sector HIV clinic in Bulawayo, Zimbabwe, between 2005 and 2009 were included in a retrospective cohort study. Participants were categorized into narrow age-bands namely: 5-9 (children), 10-14 (young adolescents) and 15-19 (older adolescents). The effect of age at ART initiation, current age (using a time-updated Lexis expansion) and transitioning from one age group to the next on LTFU was estimated using Poisson regression. RESULTS: Of 2273 participants, 1013, 875 and 385 initiated ART aged 5-9, 10-14 and 15-19 years, respectively. Unlike those starting ART as children, individuals starting ART as young adolescents had higher LTFU rates after moving to the older adolescent age-band (Adjusted rate ratio (ARR) 1.54; 95% CI: 0.94-2.55) and similarly, older adolescents had higher LTFU rates after transitioning to being young adults (ARR 1.79; 95% CI: 1.05-3.07). In older adolescents, the LTFU rate among those who started ART in that age-band was higher compared to the rate among those starting ART at a younger age (ARR = 1.70; 95% CI: 1.05, 2.77). This however did not hold true for other age-groups. CONCLUSIONS: Adolescents had higher rates of LTFU compared to other age-groups, with older adolescents at particularly high risk in all analyses. Age-updated analyses that examine movement across narrow age-bands are paramount in understanding how developmental heterogeneity in children affects HIV outcomes.

Relationship Between Time to Initiation of Antiretroviral Therapy and Treatment Outcomes: A Cohort Analysis of ART Eligible Adolescents in Zimbabwe.

BACKGROUND: Age-specific retention challenges make antiretroviral therapy (ART) initiation in adolescents difficult, often requiring a lengthy preparation process. This needs to be balanced against the benefits of starting treatment quickly. The optimal time to initiation duration in adolescents is currently unknown. OBJECTIVE: To assess the effect of time to ART initiation on mortality and loss to follow-up (LTFU) among treatment eligible adolescents. METHODS: We conducted a retrospective cohort analysis among 1499 ART eligible adolescents aged ≥10 to <19 years registered in a public sector HIV program in Bulawayo, Zimbabwe, between 2004 and 2011. Hazard ratios (HR) for mortality and LTFU were calculated for different time to ART durations using multivariate Cox regression models. RESULTS: Median follow-up duration was 1.6 years. Mortality HRs of patients who initiated at 0 to ≤7 days, >14 days to ≤1 month, >1 to ≤2 months, >2 months, and before initiation were 1.59, 1.19, 1.56, 1.08, and 0.94, respectively, compared with the reference group of >7 to ≤14 days. LTFU HRs were 1.02, 1.07, 0.85, 0.97, and 3.96, respectively. Among patients not on ART, 88% of deaths and 85% of LTFU occurred during the first 3 months after becoming ART eligible, but only 37% and 29% among adolescents on ART, respectively. CONCLUSIONS: Neither mortality or LTFU was associated with varying time to ART. The initiation process can be tailored to the adolescents' needs and individual life situations without risking to increase poor treatment outcomes. Early mortality was high despite rapid ART initiation, calling for earlier rather than faster initiation through HIV testing scale-up.

Risk of death among those awaiting treatment for HIV infection in Zimbabwe: adolescents are at particular risk.

INTRODUCTION: Mortality among HIV-positive adults awaiting antiretroviral therapy (ART) has previously been found to be high. Here, we compare adolescent pre-ART mortality to that of adults in a public sector HIV care programme in Bulawayo, Zimbabwe. METHODS: In this retrospective cohort study, we compared adolescent pre-ART outcomes with those of adults enrolled for HIV care in the same clinic. Adolescents were defined as those aged 10-19 at the time of registration. Comparisons of means and proportions were carried out using two-tailed sample t-tests and chi-square tests respectively, for normally distributed data, and the Mann-Whitney U-tests for non-normally distributed data. Loss to follow-up (LTFU) was defined as missing a scheduled appointment by three or more months. RESULTS: Between 2004 and 2010, 1382 of 1628 adolescents and 7557 of 11,106 adults who registered for HIV care met the eligibility criteria for ART. Adolescents registered at a more advanced disease stage than did adults (83% vs. 73% WHO stage III/IV, respectively, p<0.001), and the median time to ART initiation was longer for adolescents than for adults [21 (10-55) days vs. 15 (7-42) days, p<0.001]. Among the 138 adolescents and 942 adults who never commenced ART, 39 (28%) of adolescents and 135 (14%) of adults died, the remainder being LTFU. Mortality among treatment-eligible adolescents awaiting ART was significantly higher than among adults (3% vs. 1.8%, respectively, p=0.004). CONCLUSIONS: Adolescents present to ART services at a later clinical stage than adults and are at an increased risk of death prior to commencing ART. Improved and innovative HIV case-finding approaches and emphasis on prompt ART initiation in adolescents are urgently needed. Following registration, defaulter tracing should be used, whether or not ART has been commenced.

HIV-infected adolescents in southern Africa can achieve good treatment outcomes: results from a retrospective cohort study.

OBJECTIVES: In this study we examine whether adolescents treated for HIV/AIDS in southern Africa can achieve similar treatment outcomes to adults. DESIGN: We have used a retrospective cohort study design to compare outcomes for adolescents and adults commencing antiretroviral therapy (ART) between 2004 and 2010 in a public sector hospital clinic in Bulawayo, Zimbabwe. METHODS: Cox proportional hazards modelling was used to investigate risk factors for death and loss to follow-up (LTFU) (defined as missing a scheduled appointment by ≥3months). RESULTS: One thousand, seven hundred and seventy-six adolescents commenced ART, 94% having had no previous history of ART. The median age at ART initiation was 13.3 years. HIV diagnosis in 97% of adolescents occurred after presentation with clinical disease and a higher proportion had advanced HIV disease at presentation compared with adults [WHO Stage 3/4 disease (79.3 versus 65.2%, P < 0.001)]. Despite this, adolescents had no worse mortality than adults, assuming 50% mortality among those LTFU (6.4 versus 7.3 per 100 person-years, P = 0.75) with rates of loss to follow-up significantly lower than in adults (4.8 versus 9.2 per 100 person-years, P < 0.001). Among those who were followed for 5 years or more, 5.8% of adolescents switched to a second-line regimen as a result of treatment failure, compared with 2.1% of adults (P < 0.001). CONCLUSION: With adolescent-focused services, it is feasible to achieve good outcomes for adolescents in large-scale ART programs in sub-Saharan Africa. However, adolescents are at high risk of treatment failure, which compromises future drug options. Interventions to address poor adherence in adolescence should be prioritized.
