Background: The brain in the early adolescent period undergoes enhanced changes with the radical reorganisation of the neuronal network leading to improvement in cognitive capacity. A complex interplay exists between environment and genetics that influences the outcome of intellectual capability. We, therefore, aimed to evaluate the relationship between socio-demographic variables and measures of cognitive function (intelligence quotient [IQ] and academic performance) of early adolescents. Methods: The study was a descriptive cross-sectional study of early adolescents aged 10–14 years. Raven's Standard Progressive Matrices was used to assess the IQ and academic performance was assessed by obtaining the average of all the subjects' scores in the last three terms that made up an academic year. A confidence interval of 95% was assumed and a value of P < 0.05 was considered statistically significant. Results: The overall mean (standard deviation) age of the study population was 11.1 years (±1.3) with male-to-female ratio of 1:1. Female sex was associated with better academic performance with P = 0.004. The students with optimal IQ performance were more likely (61.7%) to perform above average than those with sub-optimal IQ performance (28.6%). As the mother's age increased, the likelihood of having optimal IQ performance increased 1.04 times (odds ratio [OR] = 1.04; 95 confidence interval [CI] = 1.01–1.07). Students in private schools were three times more likely to have optimal IQ performance than those from public schools (OR = 2.79; 95 CI = 1.65–4.71). Conclusion: The present study demonstrated that students' IQ performance and the female gender were associated with above-average academic performance. The predictors of optimal IQ performance found in this study were students' age, maternal age and school type.

Context: After thirty years of ratifying the child rights convention and nineteen years of the Child Rights Act, implementing child rights instruments remains challenging in Nigeria. Healthcare providers are well positioned to change the current paradigm. Aim: To examine the knowledge, perception, and practice of child rights and the influence of demographics among Nigerian doctors and nurses. Materials and Methods: A descriptive, cross-sectional online survey was done using nonprobability sampling. Pretested multiple-choice questionnaire was disseminated across Nigeria's six geopolitical zones. Performance was measured on the frequency and ratio scales. Mean scores were compared with 50% and 75% thresholds. Results: A total of 821 practitioners were analyzed (doctors, 49.8%; nurses, 50.2%). Female-to-male ratio was 2:1 (doctors, 1.2:1; nurses, 3.6:1). Overall, knowledge score was 45.1%; both groups of health workers had similar scores. Most knowledgeable were holders of fellowship qualification (53.2%, P = 0.000) and pediatric practitioners (50.6%, P = 0.000). Perception score was 58.4% overall, and performances were also similar in both groups; females and southerners performed better (59.2%, P = 0.014 and 59.6%, P = 0.000, respectively). Practice score was 67.0% overall; nurses performed better (68.3% vs. 65.6%, P = 0.005) and postbasic nurses had the best score (70.9%, P = 0.000). Conclusions: Overall, our respondents’ knowledge of child rights was poor. Their performances in perception and practice were good but not sufficient. Even though our findings may not apply to all health workers in Nigeria, we believe teaching child rights at various levels of medical and nursing education will be beneficial. Stakeholder engagements involving medical practitioners are crucial.
