Prevalence, Pattern and Factors Associated with Developmental Delay amongst Under-5 Children in Nigeria: Evidence from Multiple Indicator Cluster Survey 2011-2017.

BACKGROUND: Children develop dynamically, and when a child fails to reach age-appropriate developmental milestones compared to their peers, it is considered a developmental delay. In developing nations like Nigeria, several demographics, socioeconomic, childcare and external factors may influence the highly individualised process. This study assessed the prevalence and pattern of developmental delay, across Nigeria's geopolitical zones including identified factors associated with developmental delay, providing insight for appropriate interventions to prevent disability in affected children. METHODS: This was a secondary analysis of data from the Multiple Indicator Cluster Survey (MICS), which was carried out in rounds 4 (2011) and 5 (2016/2017). Every 5 years, the UNICEF-supported MICS cross-sectional household survey is carried out using the cluster sampling method. A semi-structured, questionnaire administered by the interviewer was used to obtain individual and household-level data. This study comprised a weighted sample of 17,373 under-5 children who had complete data from both survey rounds on characteristics deemed significant for the study. Data were analysed using SPSS version 23. Using the Chi-square test and multivariate binomial logistic regression, factors linked to developmental delay were identified, with 95% confidence intervals (CIs) provided and the significance level set at 5%. RESULTS: The mean age and sex distribution of the children surveyed in both rounds was comparable, with a male preponderance of 51.2% in round 4 and 50.4% in round 5. In both round 4 (51.2%) and round 5 (49.0%), the Northeast zone had the highest prevalence of overall developmental delay while the least prevalence was seen in the Southwest zone (20.3%) and the Southeast zone (14.7%) in round 4 and round 5, respectively. Across all the zones, delay in the literacy-numeracy domain of development was the most prevalent, with the highest (91.3% and 86.7%, respectively) in the Northeast zone during both rounds of the survey. Delay in the physical domain was, however, the least prevalent form of developmental delay across the zones, with the least in South South (20.6%) and Southeast (5.4%) in rounds 4 and 5. The odds of developmental delay were 1.5 and 1.7 times higher amongst children 4 years old than 3 years old in both rounds of the survey. The likelihood of having developmental delay was found to increase with the severity of stunting amongst the children during both rounds of the survey (odds ratio [OR] =1.5; 95% CI = 1.20-1.78 in round 4 and OR = 1.4; 95% CI = 1.16-1.58 in round 5). Children from the poorest wealth index had higher odds of developmental delay (OR = 5.8; 95% CI = 4.92-6.82 in round 4 and OR = 2.5; 95% CI = 1.99-3.10 in round 5). CONCLUSION: The prevalence of developmental delay is high across all zones; however, the burden varies amongst them. The age of the child, nutritional status and wealth index were indicators of developmental delay in Nigerian under-5 children. This underscores the need for surveillance and interventions focussed on improving child literacy, nutritional status and household standard of living across the zones.

Factors associated with immunization status among children aged 12-59 months in Lagelu local government area, Ibadan: a cross-sectional study.

Introduction: childhood deaths from preventable causes remain high in Nigeria. Although vaccines are available to combat many of these diseases, vaccine coverage remains low in many at-risk communities. With this study, we aimed to determine factors that might have impacted the use of immunization services in Ibadan, the capital of Oyo State in southwest Nigeria. Methods: we conducted a community-based cross-sectional study in a peri-urban local government area in Ibadan using a multi-stage cluster sampling technique to identify respondents for this study. The interviewer-administered questionnaire was used to obtain information on respondents and child socio-demographic details. We reviewed the child´s vaccine card to determine vaccine status. Data were analyzed using STATA version 14 at a 5% level of significance. Results: of the 265 children aged 12 to 59 months who had their vaccine cards appropriately filled, only 65.3% (n=173) received all basic vaccines, while 90.2% (n=239) and 86.8% (n=230) received 3 doses of pentavalent vaccine (PENTA) and pneumococcal conjugate vaccines (PCV-10) respectively. We found a significant difference in the completion of basic vaccination according to the caregiver´s place of residence and the mother´s educational level. Access-related barriers were frequently reported (n=24, 54.5%) as reasons for missing a due vaccine. Conclusion: improvement in vaccine coverage in this setting is necessary. Targeted health information for mothers may be a cost-efficient and sustainable approach to improve vaccine coverage for under-five children.

Experience of burden of care among adult caregivers of elderly persons in Oyo State, Nigeria: a cross-sectional study.

Introduction: caring for elderly persons is challenging for caregivers due to elderly persons´ increased dependence and reduced physical strength. This study assessed the burden of care experienced by caregivers of elderly persons in family settings. Methods: this cross-sectional study used a multistage cluster sampling technique to select 1,119 caregivers of elderly persons aged 18-59 years from one rural and one urban local government area in Oyo State, Nigeria. Interviewer-administered questionnaires collected information on caregiving arrangements and burden of care experienced (determined using the modified short version of the Zarit Burden Interview). Results: caregivers´ mean age was 38.6 ± 8.7 years with 50.2% aged ≥40 years. There were more females (59.8%) than males (40.2%) and 78.4% were married. Only 47.8% were primary caregivers, 54% cared for their parents and 2% cared for non-relatives. Prior to their caregiving, 81% reported good relationships with the elderly. Although 80.3% of the elderly were reported to be fully independent for activities of daily living, 74.0% of the caregivers experienced burden of care with 28.2% reporting severe burden. The odds of burden of care were 10 times higher among rural than urban caregivers (OR=10.09, 95%CI=5.99-17.01); eight times higher among those with poor than those with good mental health status (OR=7.90, 95%CI=4.60-13.57) three times higher among those with dependent than independent elders (OR=2.74, 95%CI=1.68-4.47). Conclusion: experience of burden of care was high among caregivers in the rural area and those with poor mental health. Community-oriented support including daycare centres and old people´s homes will provide relief to caregivers.

Awareness and utilization of female condoms among street youths in Ibadan, an urban setting in South-West Nigeria.

INTRODUCTION: Female condom awareness and use have been poorly documented in sub-Saharan region especially among street youths. This study assessed its awareness and use among street youths. METHODS: A cross-sectional study was conducted among 964 youths between ages 15 to 24 years old using questionnaires to elicit information. Univariate and multivariate analysis were conducted at 5% level of significance. RESULTS: More than half (69.9%) were males and between 20-25 years of age (61.2%). More than three-quarter (81.0%) had initiated sexual activity. Almost half (47.9%) of the respondents have heard about female condoms however only 16.8% have ever seen while 4.3% have actually ever used a female condom. Age, education, current sexual activity and experience of rape attempt were predictors of female condom awareness. CONCLUSION: Awareness of female condom was a significant predictor of utilization of female condoms. There is therefore a need for proper awareness and education on the effectiveness of female condoms.
