Which of the following is considered a physical determinant of health?

A physical determinant of health refers to environmental factors that can impact an individual's health directly. Poor air quality is a clear example of this, as it can lead to a variety of health issues, particularly respiratory problems and cardiovascular diseases. The environment in which people live, including the quality of air they breathe, plays a critical role in their overall health and wellbeing.

Other factors listed, while important in the context of health, belong to different categories. Access to education is considered a social determinant of health, as it influences health outcomes through knowledge and opportunities. Social support networks also fall under social determinants, as they relate to the relationships and community ties that can impact mental and physical health. Health literacy, likewise, is linked to how well individuals can understand and utilize health information, which is similarly categorized as a social determinant. Understanding how these determinants interact helps to create more effective health interventions and policies.
