Written by official IB examiners

Prevalence rates reveal how widespread health problems are in populations

Prevalence is the proportion of a population experiencing a health condition at a specific time, while incidence measures new cases occurring within a period.
Understanding prevalence helps identify which health problems are most common and require public health intervention.
Higher prevalence rates indicate a condition affects more people and has greater public health impact.

Multiple factors systematically affect prevalence rates across populations

Age significantly influences prevalence; for example, obesity increases with age in many developed nations.
Gender differences exist in prevalence rates, with depression more common in women and substance abuse higher in men.
Socioeconomic factors predict health outcomes; lower SES correlates with higher prevalence of stress and chronic disease.
Cultural factors shape both actual prevalence and reported prevalence; different cultures have varying stigma around mental health.
