The physical and mental development of pupils could be arrested by inadequate food intake and infection with immediate and long term consequences. This has implications on decreased school performances, lower intelligent quotient levels, poor psychosocial development, and decreased cognitive functions. This study assessed the growth and body fat distribution among pupils aged 5 - 19 years. A cross-sectional study was conducted among pupils from five primary schools in different communities around Kainji Dam. This assessment was based on a comparison with reference standards set by the World Health Organization to determine their deviations. A qualified registered nurse carried out physical measurements to obtain age, height, and body weight using electronic weighing scale and stadiometer. Data were analyzed using Anthroplusv1.0.4 software. The overall prevalence of stunting was 21.5% with 8% being severely stunted. The prevalence of thinness was 35.2% with 11.2% being wasted while the overall prevalence of underweight was not calculated for children > 10 years old. The prevalence of underweight for 5 - 10 years old children was 16.9% with 2.4% being severely underweight. The curves for both male and female children deviated from normal distribution. Females have higher percentage of stunting than males. This study revealed a high prevalence of thinness and stunting which is the consequence of poor nutrition arising from multifaceted and interrelated circumstances such as poor feeding, eating practices and repeated infection. Intervention such as Home Grown School Feeding Programme of the Government is a right step in improving the nutritional status of pupils in rural communities.

<i>Schistosoma mansoni</i>and Soil Transmitted Helminth (STH) Infections among Pregnant Women Attending Primary Health Care Facilities in Lagos Mainland, Nigeria

Journal of Biosciences and Medicines 2018年第12期6卷 64-70页

作者： babatunde adewale Olalekan Rahaman Oluwagbenga Aina Medinat A. Sulyman Public Health and Epidemiology Department Nigerian Institute of Medical Research Lagos Nigeria Zoology Department University of Lagos Lagos Nigeria Biochemistry and Nutrition Department Nigerian Institute of Medical Research Lagos Nigeria

In a cross-sectional survey among consented pregnant women, rapid diagnostic test (RDT) for malaria was carried out and stool examination was done to detect the presence of Schistosoma mansoni and soil transmitted helminthes using Kato-Katz technique. Intensity of infection was expressed as the number of eggs per gram (epg) of faeces. Prevalence of soil transmitted helminthes was 8.3% and 0.83% for Schistosoma mansoni while none was positive for malaria infection. Lack of co-infection with malaria could be connected with the intermittent preventive treatment with sulphadoxine pyrimethamine (IPTp-SP). Public health impact of soil transmitted helminthes and schistosomiasis infections in pregnancy may necessitate initiation of preventive treatment of helminth infections during pregnancy.

Background: Access to testing for SARS-CoV-2 in Nigeria is still highly restricted. Only patients who are symptomatic for SARS-CoV-2 are selected for testing. This pattern of testing will miss a large proportion of individuals with the infection who are asymptomatic and presymptomatic. This study reports the experience of a symptom-based study from a large testing centre in Nigeria. Methods: A cross-sectional study, reviewing data collected from respondents presenting at the Nigerian Institute of Medical Research (NIMR) modified drive-through center for COVID-19 test between the period March 31st and August 31st, 2020 were included in the analysis. Results: A total of 9891 participants were recruited into the study and 2465 participants (24.9%) had a positive PCR result for SARS-CoV-2. The majority of the respondents were above 18 years old, n = 9163 (93.4%). The average age of the respondents was 36.7 years (sd 13.8 years). The age of the participants has a significant effect on SARS-CoV-2 status (AOR = 1.009, CI, 1.005 to 1.012, p = 0.0001). There was a male preponderance, n = 5652 (57.6%). The odds of having a positive status for SARS-CoV-2 were 0.9 times lower for female participants. The majority of the respondents had a history of travel, n = 6788 (68.6%). Cough was the commonest symptom, n = 1062 (10.7%) followed by fever, n = 979 (9.9%). The mortality rate was 0.1%. Among the participants with comorbidity, 31 (51.7%) had positive results for SARS-CoV-2 while 29 (48.3%) had negative results. Conclusion: Symptom-based approach to testing for SARS-CoV-2 in Nigeria revealed a high positivity rate, while mortality from those tested in the study is low. Age and gender appear to play a significant role in the dynamics of the disease.
