Which of the following is a social determinant of health?

Access to quality education is indeed a social determinant of health because it significantly influences an individual's overall well-being and health outcome. Education affects health literacy, which in turn impacts a person’s ability to make informed health choices, understand health information, and navigate healthcare systems effectively. It also affects socioeconomic status, job opportunities, and access to resources, all of which play vital roles in shaping health outcomes in populations.

The other options focus more on individual or lifestyle choices and biological factors. Individual genetic predisposition relates to biological factors influencing health rather than social conditions. Personal dietary choices represent individual behaviors and habits that impact health but do not reflect the broader societal influences. Frequency of medical check-ups is related to healthcare access and utilization, which while important, is not classified as a social determinant in the same way that education and its access are viewed in public health contexts.
