As a physician of more than thirty years I get concerned when I see the emphasis put on race and economics as the sole cause of health care disparities. High cholesterol comes not just from diet, but lipid or fat disorders and also has a genetic component as deceased tennis great Arthur Ashe’s life demonstrated. Obesity correlates with diet, lack of exercise and sometimes genetics. Diabetes reflects obesity, diet, and genetics.
High blood pressure results from intrinsic poorly understood likely genetic etiologies in 90%+ of the cases; however, the influence of diet, diabetes, and obesity cannot be discounted. Lead exposure on an inner city street where polluting paint and fuel inefficient cars may travel hurt as much as the lack of trees for pollution filtration. Asthma reflects environmental exposures, smoking, and genetics. Lack of access to physicians is often the result of where you live, how much money you can pay for your care and your level of understanding about your health.
