Moreover, the burden of disability from all respiratory diseases has increased (Table 56-1), partly attributable to improved survival among children and adolescence and population growth among regions with higher sociodemographic indicators (SDIs) based on higher incomes, higher educational attainment, and reduced fertility rates.3 In 2015, asthma and chronic obstructive pulmonary disease (COPD) were ranked 11th and 14th among the leading causes of disability worldwide.2
