Which demographic factors often influence health disparities?

The correct response highlights that health disparities are influenced by a combination of race, ethnicity, gender, and age. These demographic factors are critical for understanding how various groups experience different health outcomes due to a multitude of social determinants.

Race and ethnicity contribute significantly to health disparities because they often determine access to healthcare, the quality of the care received, and the prevalence of certain health conditions within specific populations. Gender also plays a vital role, as it can affect biological factors, health-seeking behaviors, and access to services. Age is another important factor since different age groups may face unique health challenges and have distinct healthcare needs.

This comprehensive view acknowledges that health disparities are multifaceted and can't be boiled down to just one type of demographic factor, making this answer the most accurate reflection of the complexity surrounding health inequities.
