Insights
Children of parents with Chronic Obstructive Pulmonary Disease (COPD) exhibit impaired pulmonary function. This study confirms familial aggregation of COPD and reduced lung function in offspring.
Area of Science:
- Pulmonary Medicine
- Genetics and Epidemiology
- Respiratory Health
Context:
- Chronic Obstructive Pulmonary Disease (COPD) is a significant global health concern.
- Understanding familial aggregation is crucial for identifying at-risk populations.
- Previous research has explored environmental and genetic factors in COPD development.
Purpose:
- To investigate the presence of familial aggregation in pulmonary function impairment.
- To determine if offspring of COPD patients have reduced lung function (FEV1).
- To identify risk factors associated with lower FEV1 in children of COPD patients.
Summary:
- A study compared pulmonary function in children of COPD patients versus controls.
- Children of COPD patients showed significantly lower FEV1 (Forced Expiratory Volume in 1 second).
- Parental COPD severity and offspring's clinical symptoms were linked to reduced FEV1.
Impact:
- Identifies parental COPD as an independent risk factor for reduced FEV1 in children.
- Provides evidence for familial aggregation of COPD and pulmonary function impairment.
- Highlights the need for early screening and intervention in families with COPD.
Objective:
To study whether familial aggregation exists in pulmonary function impairment and COPD.
Methods:
Pulmonary function, smoking habits, history of occupational dust exposure and clinical manifestation among 117 children of 59 smokers with COPD and 55 children of 28 control smokers without COPD. A multivariate linear regression analysis was carried out to study FEV1 among the children. Logistic regression analysis was conducted to study the factors influencing the FEV1 < 70% pred.
Results:
Height and male gender were positively correlated to children's FEV1 (ml); whereas age, clinical symptoms, history of occupational dust exposure and being children of diseased probands were negatively correlated to children's FEV1 (ml). With other relevant factors adjusted, the FEV1 (ml) was lower among those being children of COPD patients; the more severe the COPD conditions of the parents, the lower the FEV1 of the children. Cigarette consumption having clinical symptoms, and being children of COPD probands showed increased risk of FEV1 below 70% predicted (OR = 1.987). Height, age, and history of occupational dust exposure were not correlated to FEV1 < 70% pred among children.
Conclusion:
Being children of COPD parents is the independent risk factor for lower FEV1 (ml) and FEV1 below 70% pred, which demonstrates the presence of familial aggregation of COPD and pulmonary function impairment.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
