    Anemia and Iron-Deficiency Anemia in Children Born to Mothers with HIV in Western Kenya
    (Sage, 2021-02-22) Oyungu, Eren; Roose, Anna W.; Ombitsa, Ananda R.; Yang, Ziyi; Vreeman, Rachel C.; McHenry, Megan S.; Pediatrics, School of Medicine
    The objective of this study was to determine and compare anemia and iron-deficiency anemia (IDA) rates in young Kenyan children who are HIV infected (HI), HIV exposed, uninfected (HEU), and HIV unexposed (HU). Questionnaires, anthropometrics, and blood samples were collected from HI, HEU, and HU aged 18 to 36 months. Descriptive statistics, Fisher’s exact tests, and linear regression were used for analysis. Of 137 total participants, HI (n = 18), HEU (n = 70), and HU (n = 49), 61.1%, 53.6%, and 36.7%, respectively, were anemic, with mean hemoglobin levels highest in HU (P = .006). After adjusting for covariates, HI (β = −9.6, 95% CI:−17.3 to −2.0) and HEU (β = −7.4, 95% CI: −12.9 to −1.9) had lower hemoglobin levels compared with HU. The proportion of children with IDA did not differ significantly across groups (P = .08). HEU have rates of anemia and IDA similar to HI. Anemia risk is generally higher in HEU than HU, even after adjusting for covariates.

    Child Development Monitoring in Well-baby Clinics in Kenya
    (Global Health and Education Projects, 2021) Oyungu, Eren; Roose, Anna; Ombitsa, Ananda R.; Vreeman, Rachel C.; McHenry, Megan S.; Pediatrics, School of Medicine
    Background: Maternal and child health (MCH) clinics represent an integrated approach for providing healthcare to pregnant women and children 0-59 months of age. Although MCH clinics are also charged with monitoring child development, which involves tracking developmental milestones, it is unclear how these services are provided or perceived within the clinic. This study aimed to describe self-reported knowledge, perceptions, and practice of developmental monitoring in selected MCH clinics in western Kenya. Methods: This cross-sectional descriptive study was conducted within six clinics. We administered a descriptive survey to measure caregiver and healthcare staff attitudes towards and awareness of developmental monitoring; we also reviewed MCH booklets to identify services received at the clinic. Data collection occurred over a period of one day at each of the six clinic sites. The data were analyzed using descriptive statistics. Results: During the study period, 78 caregiver-child pairs presented to the clinics and had their MCH booklets reviewed. The median child age was three months (interquartile range [IQR]: 1-8 months). Most caregivers were aware of weight monitoring and immunization services; however, when asked specifically about developmental monitoring, only 2.6% of caregivers were aware this service was available at the clinics. Nearly 80% of caregivers reported that they would be very interested in developmental monitoring services. Thirty-three MCH healthcare staff were interviewed about services provided and goals of clinical care. Fewer healthcare staff (60.6%) identified their roles in developmental monitoring compared to their roles in growth (90.9%) and nutritional monitoring (84.8%). Developmental milestones had not been recorded in any of the 78 MCH booklets. However, 78.1% of healthcare staff indicated support for developmental screening. Conclusion and global health implications: While developmental monitoring was valued by healthcare providers, it was not consistently performed at the six clinics in our study. We recommend further work to raise awareness about developmental monitoring and to measure the implications of increased caregiver knowledge and perceptions on developmental monitoring practice.

    Cultural Adaptation of the Bayley Scales of Infant and Toddler Development, 3rd Edition for use in Kenyan Children Aged 18–36 Months: A Psychometric Study
    (Elsevier, 2021) McHenry, Megan S.; Oyungu, Eren; Yang, Ziyi; Hines, Abbey C.; Ombitsa, Ananda R.; Vreeman, Rachel C.; Abubakar, Amina; Monahan, Patrick O.; Pediatrics, School of Medicine
    Background: The Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III) is frequently used in international child development research. No studies examine its psychometric properties when culturally adapted within the Kenyan context. Aims: To culturally adapt the Bayley-III for use in Kenya and evaluate its validity and reliability. Methods and procedures: Forward and backward translation, cognitive interviews, and a brief pilot of culturally adapted items were performed. This psychometric study was part of another study on children born to mothers with HIV in Eldoret, Kenya. One hundred seventy-two children aged 18-36 months were assessed for cognition, receptive/expressive communication, and fine/gross motor domains using the Bayley-III. Confirmatory factor analysis (CFA), inter-scale Pearson correlations, internal consistency, t-tests, and test-retest reliability were performed. Outcomes and results: The mean age of children was 22.8 (SD 4.5) months old; 52.7 % (n = 89) were male. CFA revealed that both two- and three-factor indices had good and comparable fit. Pearson correlations were high between fine motor and receptive communication (r >0.70). Internal consistency was very strong for all of the subtests, with Cronbach coefficient alpha scores ranging from 0.88 to 0.96. Known groups/convergent validity was confirmed with stunting and parental concern for delays. Test-retest reliability was good and did not differ substantially across groups. Conclusions and implications: The Kenyan adapted Bayley-III is a psychometrically acceptable tool to assess child development. The scaled and composite scores should not be used to define Kenyan developmental norms, but it can be useful for comparing groups within research settings.

    Early Childhood Development in Children Born to HIV-Infected Mothers: Perspectives From Kenyan Clinical Providers and Caregivers
    (SAGE, 2018-01-01) McHenry, Megan S.; Oyungu, Eren; McAteer, Carole I.; Ombitsa, Ananda R.; Cheng, Erika R.; Ayaya, Samuel O.; Vreeman, Rachel C.; Pediatrics, School of Medicine
    Objective. To understand the perspectives of clinical providers and caregivers regarding early childhood development (ECD) in children born to HIV-infected mothers in Kenya. Methods. This was a qualitative study of provider and caregiver perspectives on ECD at 5 Kenyan HIV clinics, using semistructured interviews and focus group discussions. Constant comparison and triangulation methods were employed to elucidate the concepts of ECD. Results. Twenty-five providers and 67 caregivers participated. While providers understood ECD in terms of milestones, caregivers strongly equated ECD with physical growth. Factors affecting ECD, such as nutrition, perinatal effects, and illness, were perceived differently by providers and caregivers. Both groups generally believed that HIV-infected children would have typical ECD if adherent to their HIV treatment. Conclusions. Important considerations regarding ECD in this population were uncovered. Understanding provider and caregiver perspectives’ on ECD in HIV-exposed children is critical for promoting ECD in this community.

    Neurodevelopmental Outcomes of Young Children Born to HIV-Infected Mothers: A Pilot Study
    (Frontiers Media, 2021-10-21) McHenry, Megan S.; Oyungu, Eren; Yang, Ziyi; Ombitsa, Ananda R.; Cherop, Cleophas; Vreeman, Rachel C.; Pediatrics, School of Medicine
    Introduction: Over 15 million children who were exposed to HIV perinatally but uninfected (HEU) are alive globally, and they are faced with multiple risk factors for poor neurodevelopment. While children who are HIV-infected (HIV+) appear to have worse neurodevelopmental scores compared to children unexposed and uninfected with HIV (HUU), the evidence is mixed in children who are HEU. This small descriptive pilot study aimed to compare neurodevelopmental scores of children who are HIV+, HEU, and HUU in Kenya. Methods: This cross-sectional pilot study included children ages 18–36 months who were HIV+, HEU, or HUU. Neurodevelopment was assessed, along with sociodemographic, lab, and growth data. Statistical analysis included descriptive statistics, one-way ANOVA, chi-squared, and adjusted linear regression models. Results: One hundred seventy two were included (n = 24 HIV+; n = 74 HEU; n = 74 HUU). Mothers of children who were HEU experienced more depressive symptoms (p < 0.001). The only neurodevelopmental differences were found among groups was that children who were HIV+ had higher receptive language scores (p = 0.007). Lower height-for-age z-scores and being left home alone were associated with worse neurodevelopmental scores. Conclusions: Being stunted, left completely alone for at least an hour within the last week, and having higher sociodemographic status were associated with worse neurodevelopmental scores. The higher levels of depressive symptoms within mothers of children who are HEU warrants further investigation.

    Preventive Health Service Coverage Among Infants and Children at Six Maternal-Child Health Clinics in Western Kenya: A Cross-Sectional Assessment
    (Springer, 2022-03) Deathe, Andrew; Oyungu, Eren; Ayaya, Samuel O.; Ombitsa, Ananda R.; McAteer, Carole I.; Vreeman, Rachel C.; McHenry, Megan S.; Pediatrics, School of Medicine
    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.
