Background

Few studies have described time-based trends of clinical and demographic characteristics of children enrolling in HIV and AIDS care and treatment services. We present findings of a study that explored time-based trends of baseline characteristics among children enrolling into 26 public HIV care facilities in Dar es Salaam, Tanzania.

Methods

Children enrolled between October 2004 and September 2011 was included in these analyses. The year of enrollment was used as the primary predictor of interest, and log linear and linear regressions model were used to analyze dichotomous and continuous variables respectively. P-values under 0.05 were considered significant.

Results

Among the 6,579 children enrolled, the proportion with advanced disease at enrollment increased from 35% to 58%, mean age increasing from 5.0 to 6.2 years (p < 0.0001), proportion of children less than 2 years decreased from 35% to 29%. While the median hemoglobin concentration rose from 9.1 g/dl to 10.3 g/dl (P <0.0001), proportion with a history of past TB dropped from 25% to 12.8% (P < 0.0001). Over time, health centers and dispensaries enrolled more children as compared to hospitals (P < 0.0001). Temeke district, which has the lowest socioeconomic status among the three districts in Dar es Salaam, had a significant increase in enrollment from 22% to 25% (P = 0.02).

Conclusion

We found that as time progressed, children were enrolled in care and treatment services at an older age sicker status as evidenced by increase in mean age and more advanced disease stage at first contact with providers. We recommend more efforts be focused on scaling up early HIV infant diagnosis and enrollment to HIV care and treatment.

BACKGROUND: We assembled a prospective cohort of 3144 children less than 15 years of age initiating antiretroviral therapy (ART) in Dar es Salaam, Tanzania. METHODS: The relationships of nutritional status and other baseline characteristics in relation to mortality were examined using Cox proportional hazards model. RESULTS: Compared with children with weight for age (WAZ) > -1, those with WAZ ≤ -2 to < -3 had a nearly double risk of death (relative risk [RR], 1.85; 95% confidence interval [CI], 1.10-3.11), and among those with WAZ ≤ -3, the risk more than tripled (RR, 3.36; 95% CI, 2.12-5.32). Other baseline risk factors for overall mortality included severe anemia (P < .001), severe immune suppression (P = .02), history of tuberculosis (P = .01), opportunistic infections (P < .001), living in the poorest district (P < .001), and advanced World Health Organization stage (P = .003). CONCLUSIONS: To sustain the obtained benefit of ART in this setting, interventions to improve nutritional status may be used as an adjunct to ART.
