Final answer:
Health is influenced by a combination of material, psychosocial, political economy, cultural/behavioural, and lifecourse factors, as outlined in the biopsychosocial model of health psychology.
Step-by-step explanation:
The factors influencing health include material, psychosocial, political economy, cultural/behavioural, and lifecourse factors. These ascertain that health outcomes are deeply connected with lifestyle choices, societal influences, and personal decision-making. Health psychology utilizes the biopsychosocial model to explain how health is affected by the mixture of biological, psychological, and sociocultural factors. Factors like diet, exercise, behavior, psychological stress, social relationships and genetics all interact to affect an individual's health. Additionally, disparities in health among different racial, ethnic, and gender groups can arise due to variations in these influences.
