Which statement best describes the pattern of leading causes of death across age groups?

• A. They vary by region
• B. They vary by gender
• C. They vary by time
• D. They vary by age

Answer: (D)

The main concept is that the leading causes of death change as people age due to how biology, risk exposure, and health factors evolve over a lifespan. In infancy and childhood, congenital anomalies, perinatal conditions, and accidents or sudden events often top the list. As people move into adulthood, injuries, certain diseases related to lifestyle, and some cancers begin to rise. In older adults, chronic conditions—especially cardiovascular disease and cancer—become the dominant causes. This age-related progression explains why the pattern of leading causes varies by age: the dominant health risks shift with each life stage. Regions, gender, or time can influence mortality, but the clearest overarching pattern across the full age spectrum is how leading causes differ as people grow older.
