Which of the following is considered an environmental determinant affecting health?

• A. Geography
• B. Genetics
• C. Vaccination status
• D. Immunity

Answer: (A)

Environmental determinants are external conditions that influence health, including where people live and the physical environment around them. Geography fits this idea because a location shapes numerous health influences: the climate and surrounding environment can affect exposure to diseases, pollution, and natural hazards, and it also influences access to housing, clean water, sanitation, and health services. These location-based factors are outside the individual’s biology or choices and thus constitute environmental determinants of health. In contrast, genetics refers to inherited biological traits, vaccination status reflects an intervention or health behavior, and immunity is a biological state of protection, not an external environmental factor.
