About this trial
The goal of this cross-sectional observational study is to estimate the prevalence of lung function impairment as measured by spirometry in a population of Gambian women aged 15 and older. The main question\[s\] it aims to answer are:
* What is the prevalence of lung function impairment in Gambian women * What is the prevalence of eosinophilic inflammation in Gambian women
Consenting participants will undergo
* Spirometry * Fractional exhaled nitric oxide (FENO) testing * α1-antitrypsin testing in patients with lung function impairment as assessed by spirometry
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Self-identified female sex
Age > 15 years: This age cutoff was chosen (as opposed to 18) because of the unique cultural norms and practices in the country where experiences and exposures occur at an earlier age than women in Western countries.
Disqualifiers
Age < 15 years
Non-resident household member
Any acutely unwell individual
Pregnancy

All women older than 15 years in The Gambia

Primary outcomes
Prevalence of lung function Impairment as measured by spirometry
Certified technicians will perform Spirometry testing to measure lung function parameters such as FEV1, FVC, and FEV1/FVC ratio. Results will be interpreted by two Pulmonologists using GLI reference equations and z-scores. Bronchodilator reversibility is defined as an improvement of over 10% in FEV1 after albuterol sulfate administration. Lung function impairment will be assessed based on z-scores, with normal lung function being z-scores greater than -1.645, mild impairment between -1.65 and -2.5, moderate impairment between -2.51 and -4, and severe impairment below -4.1.
Secondary outcomes
Prevalence of Type II (Eosinophilic) inflammation in Gambian Women
FENO measurements will be taken using handheld devices called NIOX VERO. These devices are compliant with guidelines set by the American Thoracic Society and European Respiratory Society. To measure FENO, participants will be instructed to exhale into the device through a filtered mouthpiece. The exhaling process will be regulated to maintain a controlled flow rate and pressure for a duration of 10 seconds.
