Non-Smoking COPD: Why Do Women Have a Higher Prevalence?
Highlights:
- Chronic obstructive pulmonary disease (COPD) is a lung disease that causes restriction of airflow
- A recent study has shown that women and older adults are at a higher risk of non-smoking COPD
- High levels of indoor pollution caused by biomass fuel could be the reason behind the prevalence
Chronic obstructive pulmonary disease (COPD) is a prevalent lung condition that causes reduced airflow and breathing difficulties. The lungs of persons with COPD might become damaged due to mucus. Coughing, occasionally with phlegm, difficulty breathing, wheezing, and fatigue are all symptoms (1✔).
Smoking is an important risk factor for COPD, which has long been thought to be a smoker's disease. However, non-smokers now account for one-third of all COPD patients worldwide.
Women and Older Adults at High Risk of Non-Smoking COPD
Women and older persons are more likely to have non-smoking COPD, according to a new systematic study published online in the journal Respiratory Medicine (2✔).‘The reason behind the increase in the prevalence of non-smoking COPD in women could be indoor pollution. #COPD’
Through a search of the Embase and PubMed databases, a group of Spanish researchers conducted a systematic assessment of the literature to describe COPD in patients who had never smoked.
The review excluded studies in which patients self-reported COPD based on their symptoms or defined COPD based on pre-bronchodilator FEV1/FVC ratio measurements.
Non-smokers were people who had never smoked or had smoked 100 cigarettes in their lifetime or 1 cigarette daily in the previous 6 months. In total, 17 clinical trials were included in the final analysis.
The analysis covered 57,146 participants in total. 25,047 of them had never smoked. 2655 of the non-smokers had non-smoking COPD. Data analysis revealed that COPD was more common in women and older persons among nonsmokers. They also had a greater prevalence of co-morbidities.
Indoor Pollution: The Answer for High Prevalence of Non-Smoking COPD in Women
This study compares the COPD symptoms of non-smokers versus smokers. The increased frequency among women, particularly in low- and middle-income countries, could be attributed to high levels of indoor pollution caused by the biomass fuel.The review, however, highlighted a lack of adequate evidence, notably addressing non-smoker COPD, as only two of the 17 studies included in the analysis had an exclusive non-smoker study sample.
Given that nonsmokers account for at least one-third of all COPD patients, there is an urgent need for additional studies to better understand the natural history as well as clinical aspects of the disease in this patient group when compared to smokers.
