Major Health Concern for Middle-Aged Adults
During middle adulthood, generally considered to be from the mid-30s to the mid-60s, individuals often face an increased risk of developing chronic diseases. While aging signs such as wrinkles and gray hair become visible, more serious health concerns arise. One major health concern for individuals in this age group is cardiovascular disease, which includes a class of diseases that involve the heart and blood vessels.
Cardiovascular disease is the leading cause of death worldwide, and although most cases are diagnosed in people over age 60, the onset is typically earlier in men by about a decade. Risk factors contributing to cardiovascular disease include smoking, obesity, diabetes, high blood cholesterol, and a sedentary lifestyle. It is not uncommon for middle-aged adults to face diagnoses of other conditions like type 2 diabetes and cancer, which are the chief causes for mortality among this demographic.
