Chronic Obstructive Lung Disease

Transcription

1 Chronic Obstructive Lung Disease HIGHLIGHTS According to the 23 Canadian Community Health Survey (CCHS), one out of every 1 seniors living in Peel reported that they had asthma, as diagnosed by a health-care professional. In 23, Chronic Obstructive Lung Disease (COLD) was the third leading cause of emergency department visits among Peel seniors for males and fifth leading cause for females. COLD was the third leading cause of death for female seniors in Peel and the fifth leading cause of death for male seniors in 21. Introduction Chronic Obstructive Lung Disease (COLD) refers to a number of chronic lung disorders that obstruct the airways. Although Chronic Obstructive Lung Disease and Chronic Obstructive Pulmonary Disease (COPD) are often used interchangeably, COLD includes asthma, bronchiectasis, and extrinsic allergic alveolitis, whereas COPD does not. COPD consists only of bronchitis, emphysema, and chronic airways obstruction not elsewhere classified. 88 Prevalence of Chronic Obstructive Lung Disease The only releasable prevalence data available for COLD in Peel seniors are for asthma. Asthma is a chronic disorder characterized by symptoms of cough, shortness of breath, chest tightness and wheeze. According to the 23 Canadian Community Health Survey (CCHS), one out of every 1 seniors living in Peel reported that they had asthma, as diagnosed by a health-care professional. * The proportion in Ontario was lower (7%). In 23, the reported prevalence of chronic bronchitis among Ontario seniors was 5%, while the reported prevalence of emphysema and other chronic obstructive pulmonary disease was 4%. The prevalence of chronic bronchitis was higher among females than males in the age group 65 to 74 years old while the prevalence of emphysema and other COLD was slightly higher among males, especially among seniors aged 75 years and older. Emergency Department Visits for Chronic Obstructive Lung Disease In 23, COLD was the third leading cause of emergency department visits among Peel seniors for males and fifth leading cause for females. The rates for emergency department visits increased by age for males up to 89 years of age and peaked for women 9 years and older (see Figure 11.1). * Data should be interpreted with caution due to high sampling variability.

4 Mortality from Chronic Obstructive Lung Disease Similar to lung cancer, chronic obstructive lung disease (COLD) was a significant cause of death among seniors in Peel. COLD was the third leading cause of death for female seniors in Peel and the fifth leading cause of death for male seniors in 21. The mortality rate due to COLD was relatively stable in Ontario (approximately 2 per 1, seniors) between 1986 and 21 (see Figure 11.4). Mortality rates due to COLD among seniors in Peel were lower compared to Ontario and declined between 1998 and 21.

The difference in the mortality rates for COLD between males and females has been narrower in more recent years (2 and 21) compared to the mid-198s. In 21, the mortality rate for COLD increased by age group in Peel for both males and females, and was higher among males across all age groups (see Figure 11.5). 144 Seniors Health Report 26
