“…Studies in Nigerian schoolchildren aged 5 to 20 years have demonstrated mean FVC and FEV1 values that were significantly lower than those of their white counterparts [36]. We therefore interpreted normal Spirometry values in this study by comparing values obtained to reference values recorded from a Nigerian study on children of both sexes and to a regional African study on African children [37], therefore interpreting pulmonary function with an emphasis on ethnic impact as advocated by some authors. The interpretation of static lung function in children of African descent is limited due to inappropriate reference equations [25].…”

Rapid urbanization and population migration encountered in developing countries results in an increasing need for transportation. To investigate the impact of vehicular emissions on air pollution/quality and respiratory health we conducted a comparative 2:1 cross-sectional study in rural and urban communities, 150 adult respondents and 30 children comprised the study population. Structured interviewer administered questionnaires; Clinical respiratory examination and digital Spirometry were conducted. Informed consent was obtained; data were analyzed using Epi info statistical software version 7. Results showed Mean age: (36.3± 12.9 years), Linear height: (median 1.65, range: 1.40 – 1.86). Adult Male: female ratio 1:1. Average Distance of households to roads/highway: 36.03±23.79 meters and prevalent duration of daily transit 2- 5 hours. In urban settlements: distance to highway/road <50 meters (OR 32.4, 95% CI: 8.57- 122.3) and Non-use of protective devices (OR: 12.43, 95% CI: 2.60-59.34) showed significant associations. Twenty two (22) Spirometry results were within the obstructive index. Abnormalities detected on Spirometry in the absence of a history of respiratory conditions or abnormalities on clinical chest examination require further investigation. Recommendations were targeted to improve health education, provide sustainable mass transit, urban planning, support focused research and ensure effective emissions control.

“…While some authors have found obstructive lung disease to be more common among female children, we reported more males with obstructive pattern. 15 , 19 Although female children are usually more exposed to biomass, 19 , 24 some studies have reported a higher prevalence of obstructive lung disease in males during the pre-pubertal period with a reversal at puberty that has been attributed to the effect of hormones. 37 The mean age of the children in this study was within the pre-pubertal age and could be the reason for our finding.…”

“…Most reports have focused on comparisons of mean differences in spirometric indices based on demographics and health status. 14 , 15 Few have interpreted their findings using globally accepted reference standards like the Global Lung Initiative (GLI-2012). The GLI-2012 has been shown to be applicable in children and adults (3-95 years) from different countries as it eliminates age, gender, ethnic, and height bias in lung function interpretation.…”

Background: There is paucity of data on objectively measured lung function abnormalities in Nigerian children using diagnostic testing methods such as spirometry. Such assessments could prompt early diagnosis and therapeutic interventions. Methods: This was a cross sectional study among children aged 6 to 12 years in South-Eastern Nigeria. We selected participants from one school using a multistage stratified random sampling technique. A structured respiratory questionnaire was administered to obtain necessary data. The lung functions of the children were measured by spirometry. We used Lower Limits of Normal (LLN) based on GLI reference equations for African-American and mixed ethnicities to define abnormal spirometry. We studied the association between the exposures and lung function using logistic regression/chi-squared tests. Results: A total of 145 children performed acceptable and repeatable tests. There were 73 males (50.3%), mean age of 9.13 years (+1.5) and age range 6 to 12 years. Frequency of respiratory symptoms was cough- 64 (44.1%) and wheeze in 19 (13.1%). Using GLI for African-Americans, fifty-five (37.9%) children had abnormal spirometryobstructive pattern in 40 (27.6%) and restrictive pattern in 15 (10.3%). The two references showed significant differences in interpretation of abnormality (χ2 = 72.86; P < .001). Respiratory symptom-wheeze was an independent determinant of abnormal lung function in this population.(OR = 0.31; 95%CI: 0.10–0.94; P = .04) Conclusion: There is a high burden of respiratory symptoms and abnormal spirometry among these children. The need for objective evaluation of lung function especially for children with respiratory symptoms is evident.

“…In spirometry, lung function indices commonly used for the estimation of lung function are -forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1 ), FVC/FEV 1 ratio and peak expiratory flow rate (PEFR) 6 . Predictive values of these indices are essential for meaningful clinical interpretation to narrow down respiratory diseases.…”

Background: The prevalence of asthma in Bangladesh is about 7%. The spirometric values in healthy children were obtained in a single urban school more than a decade ago. No rural data is available till date. Objective: To determine the spirometric values of healthy school going children in three rural schools of Bangladesh. Materials and Methods: This cross-sectional study was carried out from July 2019 to June 2020 among 300 healthy children among both boys and girls aged 11 to 15 years in three rural schools. Among 350 approached students 332 students responded to the study, 18 students did not meet inclusion criteria and 14 students could not follow spirometry procedure. Informed written consent was taken from guardians. History regarding socio-demographic profile, passive smoking, concurrent or past respiratory illness and medication were taken and weight, height and BMI were measured of the children. Spirometry was done with spirometer machine and reports were generated by software installed in a laptop. Results: Boys showed higher FVC, FEV1 and PEFR but lower FEV1/FVC ratio than those of girls. Regression equations for lung function values were determined for boys and girls considering height as independent variable. Conclusions: Spirometric indices were higher in boys than those of girls and they tended to increase with height, except FEV1/FVC ratio that was higher in girls with a negative correlation with height.
