RESUMO
OBJECTIVES: Despite the substantial reduction of child mortality in recent decades, Kenya still strives to provide universal healthcare access and to meet other international benchmarks for child health. This study aimed to describe child health service coverage among children visiting six maternal and child health (MCH) clinics in western Kenya. METHODS: In a cross-sectional study of Kenyan children who are under the age of 5 years presenting to MCH clinics, child health records were reviewed to determine coverage of immunizations, growth monitoring, vitamin A supplementation, and deworming. Among 78 children and their caregivers, nearly 70% of children were fully vaccinated for their age. RESULTS: We found a significant disparity in full vaccination coverage by gender (p = 0.017), as males had 3.5 × higher odds of being fully vaccinated compared to females. Further, full vaccination coverage also varied across MCH clinic sites ranging from 43.8 to 92.9%. CONCLUSIONS FOR PRACTICE: Health service coverage for Kenyan children in this study is consistent with national and sub-national findings; however, our study found a significant gender equity gap in coverage at these six clinics that warrants further investigation to ensure that all children receive critical preventative services.

BACKGROUND: Traditional medication adherence measures do not account for the pharmacokinetic (PK) properties of the drugs, potentially misrepresenting true therapeutic exposure. METHODS: In a population of HIV-infected Kenyan children on antiretroviral therapy including nevirapine (NVP), we used a one-compartment model with previously established PK parameters and Medication Event Monitoring Systems (MEMS®)-recorded dosing times to estimate the mean plasma concentration of NVP (Cp) in individual patients during 1 month of follow-up. Intended NVP concentration (Cp') was calculated under a perfectly followed dosing regimen and frequency. The ratio between the two (R = Cp/Cp') characterized the patient's NVP exposure as compared to intended level. Smaller R values indicated poorer adherence. We validated R by evaluating its association with MEMS®-defined adherence, CD4%, and spot-check NVP plasma concentrations assessed at 1 month. RESULTS: In data from 152 children (82 female), children were mean age 7.7 years (range 1.5-14.9) and on NVP an average of 2.2 years. Mean MEMS® adherence was 79%. The mean value of R was 1.11 (SD 0.37). R was positively associated with MEMS® adherence (p < 0.0001), and lower-than-median R values were significantly associated with lower NVP drug concentrations (p = 0.0018) and lower CD4% (p = 0.0178), confirming a smaller R value showed poorer adherence. CONCLUSION: The proposed adherence measures, R, captured patient drug-taking behaviours and PK properties.
