Academic performance and intelligence quotient of primary school children in Enugu.

INTRODUCTION: intellectual capacity measured as intelligence quotient (IQ) is one of the determinants of school performance of children. It influences academic achievement, future personal health, social well-being and therefore, is of public health significance. The objective of the study was to determine the intelligence quotient (IQ) and academic performance of primary school children in Enugu-East LGA. METHODS: children who met the inclusion criteria were recruited from both public and private primary schools in the Local Government Area (LGA) using a proportionate multistage sampling technique. Academic performance was classified into high, average and low academic using past records of class assessment. Intelligence quotient was assessed using the Raven´s Standard Progressive Matrices (RSPM) and was grouped into optimal and suboptimal. A semi-structured questionnaire was used to obtain data such as-age, gender, socio-economic indices and family size of the study participants. Analysis was done with Statistical Package for Social Sciences (IBM-SPSS). RESULTS: a total of 1,122 pupils aged 6 to 12 years were recruited. Optimal IQ and high academic performance were found in 54.0% and 58.8% of the study participants. Being from upper social class, in private school, and family size less than 4 were the significant determinants of high IQ and good academic performance (p<0.001). CONCLUSION: low socio-economic status, large family size and public school attendance impact negatively on IQ and academic performance. Hence, measures to curb large family sizes (i.e.>4 children) and improve the socio-economic status of families are needed environmental measures to improve intelligence and academic performance.

Impact of zinc on sexual maturation of female sickle cell anemia (SCA) children in Enugu, Southeast Nigeria.

Adolescence is an important developmental period of childhood. Good health and adequate nutrition consisting major food constituents and trace elements like zinc are fundamental for optimal sexual maturation. To determine the relationship between zinc levels and pattern of breast and pubic hair development, as well as menarcheal age of female SCA children aged 6-18 years and their matched controls with hemoglobin genotype AA. Cross sectional, case-control study. Information on biodata, age at menarche, medical and drug history as well as 24-hour dietary recall was documented using interviewer administered questionnaire. Sexual maturation was assessed using Tanner staging and zinc levels determined using Atomic absorption spectrophotometer. Eighty-one subjects were compared with 81 controls. There was significant delay in the mean age of attainment of various Tanner stages of breast and pubic hair in the subjects. Mean age of 14.81 ± 1.07 years at menarche in subjects was significantly higher than 12.62 ± 1.18 years in controls (p = 0.001). Serum zinc of 58.01 ± 10.58 µg/dl in subjects was significantly lower than 68.37 ± 8.67 µg/dl in controls (p = 0.001). Serum zinc levels were found to have a significant positive relationship with stages of sexual maturation and mean age at menarche. Reduced serum zinc in children with SCA was associated with delayed sexual maturation.

Paediatricians' perception about oral healthcare of children in Nigeria.

BACKGROUND: Majority of the oral diseases in children are preventable. The paediatricians owing to the unique position they occupy in child care are invaluable in achieving standard oral and dental healthcare in children. This study was aimed at assessing the paediatricians' views on basic oral healthcare in children in Nigeria. METHODS: This was a cross sectional descriptive study. Respondents were paediatricians attending the 2015 Annual General Meeting and Scientific Conference of the Paediatric Association of Nigeria. Relevant information sought from the respondents included: socio- demographic characteristics, duration and location of practice; specific questions on knowledge of basic oral health care in children and recommendations for improvement in knowledge of oral and dental health among paediatricians based on standard clinical guidelines. Data was analyzed using the SPSS version 20.0 and presented in simple frequencies and percentages. Test of associations was done using chi- square while logistic regression analysis was used to determine significantly associated variables (p < 0.05). RESULTS: A total of 121 paediatricians were recruited. 108 (89.3 %) reported that children should be referred to dental health care when caregivers/older patients report dental problems (x (2) = 9.377; p = 0.02). 53.7 % felt that examination of the oral cavity should be routine while 61 (50.4 %) of them reported that health education should be given to caregivers/mothers about nursing caries starting early in life. Majority of the respondents 66 (54.5 %) disapproved gum pad cleaning of young infants. 32 (26.4 %) suggested starting tooth brushing in infants as soon as a tooth appear in a child while 112 (92.6 %) recommended the disapproval of pacifiers in infants/younger children. 93 (76.9 %) were of the opinion that the paediatrician is competent in identifying and handling of basic oral health care in children. However, 108 (89.3 %) recommended that the current postgraduate curriculum in paediatrics should incorporate knowledge of basic oral health care in children. CONCLUSION: Majority of the paediatricians were found to have limited knowledge about some basic oral health care in children. It is recommended that the current postgraduate training curriculum in paediatrics in our setting should incorporate knowledge of basic oral healthcare in children.

Bioelectric impedance analysis of body composition of children and adolescents with sickle cell anemia in Enugu, Nigeria.

BACKGROUND: Body composition indices are widely used to evaluate growth and nutrition in children, particularly those with sickle cell anemia (SCA), who are known to have impaired growth, impaired skeletal maturation, and delayed puberty. The current study is aimed at determining the body composition of children with SCA. METHODS: Consecutive selection of SCA children aged 6 to 18 years, who served as subjects and their age and gender matched children with HbAA (controls), selected using multi-stage systematic sampling. It was a cross-sectional descriptive study conducted at the pediatric hematology and oncology clinic. Bioelectric impedance analysis was used to determine the body composition parameters, including weight, body fat percentage (BFP), visceral fat percentage, body mass index (BMI), skeletal muscle percentage, and resting metabolic rate. Data were analyzed using SPSS 16.0 at P < 0.05. RESULTS: One hundred and thirty-two subjects and controls respectively were studied. Subjects had lower body composition parameters compared with controls, with the older male subjects aged 10 to 18 years, having lower body composition indices (weight, height, BMI, and BFP) compared with controls. Visceral fat percentage was low in both subjects and controls. CONCLUSIONS: Children with SCA, particularly the older males, have impaired body composition indices. There is a need to conduct further studies to determine the longitudinal aspects of growth as well as quantitative and qualitative assessment of nutritional intake in children with SCA, which will inform higher alimentation requirements for HbSS children as compared with HbAA individuals.
