Smoking is a risk factor for cardiovascular disease, cancer, COPD and asthma. While the elderly population currently represents around 10% of the total number of National Health Insurance beneficiaries, they are responsible for around 32% of the total health insurance expenditure (HERA, 2010a). In 2010 these expenditures represented between 11% and 14% of the entire Korean health budget. The IDF also estimates that expenditure on diabetes will increase from between 7.3 billion in 2010 to 10.3 billion dollars by the year 2030 (Zhang, 2010). Furthermore, while Korea spends a large slice of its health budget looking after people with diabetes, Korean mean expenditure per person with diabetes is relatively low (Figure 3.4).
