Health risksAs older people are at greater risk of many diseases and disabilities, it is important for this population to avoid health risks that could increase the probability of these threats. However, in 2020, around 8.9 percent of adults aged 65 years and older still smoked cigarettes, a slight increase from previous years. Furthermore, an estimated 28.9 percent of older adults in the U.S. were obese in 2020, an increase from 25.3 percent in 2013.
One of the worst diseases that older people face is inarguably Alzheimer's disease, with an estimated 13.8 million older people expected to suffer from the disease by 2050. In 2019, the death rate from Alzheimer's among those aged 85 years and older was 1,191 per 100,000 population. Alzheimer's disease is currently the sixth leading cause of death in the United States.
