- Respiratory diseases were the second leading cause of death in Middlesex-London between 2005 and 2007 (Fig. 3.6).
- The hospitalization rates for respiratory disease in Middlesex-London decreased between 2003 and 2007, but have since been increasing (Fig. 6.10).
- Similar to cardiovascular disease, hospitalization rates for respiratory diseases in Middlesex-London were significantly lower than rates in Ontario up to 2011 and the Peer Group (Fig. 6.10).
- Females had a significantly lower rate of respiratory disease than males throughout the entire time period (data not shown).
- The pattern for hospitalization rates across age groups looks a bit different for respiratory disease compared to that for cardiovascular disease. The difference being that the rates were significantly lower in the age group 20-44 compared to both 0-19 and 45-64. Furthermore, there was an increasing trend between 2003 and 2013 in the oldest age group (75+), whereas the rates remained consistent in the other age groups (data not shown).
Chronic Obstructive Pulmonary Disorder
- The rate of hospitalizations for chronic obstructive pulmonary disorder (COPD) in Middlesex-London was generally lower than the provincial rates (with the exception of 2012) and Peer Group rates (Fig. 6.11).
- There was no significant decline in COPD rates between 2003 and 2013 for Middlesex-London (Fig. 6.11).
- The rate was generally higher in males than in females, but this difference was not statistically significant between 2011 and 2013 (data not shown).
- Rates of COPD increased significantly as age group increased (data not shown).
- Asthma-related hospitalization rates had a smaller burden on the population compared to those of chronic obstructive pulmonary disorder (Fig. 6.12 and Fig. 6.11).
- Asthma-related hospitalization rates declined substantially between 2005 and 2007, but have since remained stable. This drop was also observed in other parts of Ontario (Fig. 6.12).
- The trend indicates that rates for asthma hospitalizations in Middlesex-London were significantly lower than the provincial and Peer Group rates, but the gap has been closing starting in 2011 (Fig. 6.12).
Hospitalization rates due to asthma did not differ significantly between males and females during the years 2003-2013. Among those under the age of 20 asthma rates decreased substantially during this time period, but remained more stable in other age groups. Although hospitalization rates are still highest among 0-19 year olds, and remain significantly higher than rates among 20-64 year olds, they are no longer significantly more likely to be hospitalized due to asthma compared to those aged 75 and over (data not shown).
Population Health Assessment and Surveillance Protocol - Section 1, Subsections b-iii, vii
Chronic Disease Prevention Standard - Requirement #1
Chronic respiratory diseases are chronic diseases of the airways and other parts of the lung.
When the population is divided into five groups by level of household income these groups are called ‘income quintiles’. The proportion of the population in each quintile is equal.
