Several factors influence the incidence of smoking-related diseases:
1. Prevalence of Smoking: Higher smoking rates lead to a higher incidence of smoking-related diseases. 2. Age: Older populations tend to have a higher incidence due to cumulative exposure. 3. Gender: Historically, men have had higher smoking rates, but this gap is closing in many countries. 4. Socioeconomic Status: Lower socioeconomic groups often have higher smoking rates and consequently higher disease incidence. 5. Public Health Policies: Effective policies, such as smoking bans and tobacco taxes, can reduce smoking prevalence and incidence of related diseases.
