The relationship between lung function and indoor air pollution among rural women in the Niger Delta region of Nigeria

Background: Burning of biomass is widely used by the rural poor for energy generation. Long term exposure to biomass smoke is believed to affect lung function and cause respiratory symptoms. Materials and Methods: Women with long term occupational exposure to burning firewood were recruited from a rural fishing community in Nigeria. A questionnaire was used to obtain information on symptoms of chronic bronchitis and spirometery was performed to measure lung function. Data obtained from the subjects was compared with that from healthy controls. Results: Six hundred and eighty six women were recruited for this study made up of 342 subjects and 346 controls. Sixty eight (19.9%) of the subjects had chronic bronchitis compared with eight (2.3%) of the controls (χ2 = 54.0, P < 0.001). The subjects had lower values for the lung function as well as the percentage predicted values (P < 0.05). Fish smoking and chronic bronchitis were significantly associated with predicted lung volumes. Conclusion: Chronic exposure to biomass smoke is associated with chronic bronchitis and reduced lung functions in women engaged in fish smoking

A retrospective review of the factors that negatively influenced the eradication of polio in South-South, Nigeria

Background: The endemic nature of poliomyelitis in Nigeria was a source of concern to many given the global efforts aimed at eradicating the scourge. In this study, the factors that influenced the eradication of this malady in South-South Nigeria (Akwa Ibom and Cross River State) were investigated. Four null hypotheses, drawn on these factors (including culture belief, religious difference, language and the prevalence of ethnic conflict) guided the investigation. The main thrust of this study was to examine how socio-cultural factors negatively influenced the eradication of polio in the study area. Methods: Through stratified random and purposive sampling techniques, 600 adult men and women who had children were selected for the study. A structured questionnaire constructed by the researcher was used in data collection. Data analysis was carried out using one-way ANOVA and independent t-test statistical tools. Results: The findings were that cultural belief and religious affiliation exerted significant influence on the people&rsquo;s effort towards polio eradication. Conclusion: The study indicated that the low use of health services by the people was brought about by variation in these variables. Among other things, it was suggested that continuous awareness campaigns be carried out to educate the people on the need for immunization anchored in science and technology

Spectrum of COVID-19 infection in children in Southern Nigeria

Background: Corona virus disease 2019 (COVID-19) is a global pandemic that affects all age groups. Infected asymptomatic children can transmit the disease to vulnerable adults with co-morbidities resulting in severe disease in the latter. There are few reports of COVID-19 in children in Sub-Saharan Africa in general and in Nigeria in particular.Aim: To determine the prevalence, symptoms and risk factors for COVID-19 in Southern Nigerian children.Methods: This was a one-year retrospective cross-sectional study between April 2020 and March 2021. Data of all children tested for COVID-19 was extracted from the Epidemiology unit of Akwa Ibom state ministry of health. All patient identifiers were omitted and data was analyzed using STATA version 13.Results: Two hundred and fifty five children (2.25%) out of a total of 11,289 people were tested for COVID-19. Fifty -four children (0.47%) of the total number of persons tested for COVID-19 were positive. Twenty one percent of the 255 children tested were positive for COVID-19. Two hundred and fifty- four (99.6%) of children that were tested had a positive history of contact with a confirmed COVID-19 case. Five (9.3%) of COVID-19 positive children were symptomatic. The commonest symptoms seen were Fever (90.9%), Anosmia (63.6%) and Aguesia (36.4%). Increasing age (15 years and above) was significantly associated with COVID-19 positivity (p=0.000). In addition, the presence of symptoms was significantly associated with COVID-19 positivity (p=0.04).Conclusion/Recommendation: The prevalence of COVID-19 in Southern Nigerian children is low. Majority of the children have asymptomatic disease. Increasing age is significantly associated with COVID-19 positivity. We recommend increased COVID-19 testing in the general children population
