Rural living easier on the lungs

Living in the country may be good for your respiratory health, according to a study conducted in Scotland, which suggests that rural as opposed to urban dwelling is associated with a lower prevalence of Asthma.

Moreover, while the prevalence of COPD (Chronic obstructive pulmonary disease) and emphysema, which are caused primarily by smoking, is similar among country and city dwellers, living in the country appears to be associated with better health status among subjects with these two lung ailments, the study hints.

For their study, Lisa Iversen and colleagues from the University of Aberdeen in the UK analyzed responses to a mailed health questionnaire returned by more than 1,000 adults living in rural areas of Scotland and nearly 1,500 living in urban areas of Scotland.

In analyzing the data, the investigators discovered that the prevalence of "any" lung illness was 28-percent lower among those living in the country compared with those living in cities.

Asthma is an inflammatory disorder of the airways, characterized by periodic attacks of wheezing, shortness of breath, chest tightness, and coughing.

Causes, incidence, and risk factors

Asthma is a disease in which inflammation of the airways causes airflow into and out of the lungs to be restricted. When an asthma attack occurs, the muscles of the bronchial tree become tight and the lining of the air passages swells, reducing airflow and producing the characteristic wheezing sound. Mucus production is increased.

Most people with asthma have periodic wheezing attacks separated by symptom-free periods. Some asthmatics have chronic shortness of breath with episodes of increased shortness of breath. Other asthmatics may have cough as their predominant symptom. Asthma attacks can last minutes to days, and can become dangerous if the airflow becomes severely restricted.

The prevalence of Asthma was 41-percent lower among the rural residents compared with the city dwellers, whereas the prevalence of Eczema/dermatitis was 33-percent lower in the country.

Fewer people living in rural areas reported symptoms indicative of Asthma such as persistent cough and phlegm and breathlessness and wheeze, the investigators report in the medical journal Chest.

People living in the country who suffered from COPD, emphysema, or cough or phlegm symptoms had markedly better quality of life scores than their urban counterparts.
