11. Obesity

Obesity is an important senior health risk factor for heart disease, diabetes, and cancer — all chronic conditions that impact quality of life. As the numbers on the scale increase, so does the risk for disease. Of the adults between 65 and 74, 36.2 percent of men and 40.7 percent of women are obese — meaning that their body mass index is greater than or equal to 30 — according to the CDC. It can also be a signal that an older adult isn’t as active or mobile as he or she once was.
12. Depression
According to the American Psychological Association, 15 to 20 percent of Americans over 65 have experienced depression. A threat to senior health, depression can lower immunity and can compromise a person’s ability to fight infections. In addition to treatment with medication and therapy, other ways to improve senior living might be to increase physical activity — 59.4 percent of adults 65 and older don’t meet CDC recommendations for exercise— or to interact socially more — seniors report spending just 8 to 11 percent of their free time with family and friends, according to the Federal Interagency Forum on Aging-Related Statistics.
