Coronary heart disease was the leading cause of death for people aged 45–64 and people aged 75–84. For people aged 65–74, the leading cause of death was lung cancer followed by coronary heart disease, and for people aged 85 and over, it was dementia including Alzheimer's disease, followed by coronary heart disease.
The major cause of death in the 55-64 age group is cancer followed by heart disease and injury. In the 75+ age group, the leading cause shifts to heart disease, and injury drops below Chronic Obstructive Pulmonary Disease (COPD), cerebrovascular diseases, and pneumonia.
#1: Heart Disease
The top cause of death has not changed.
The study, supported by the American Insurance Group, found that, on average, a 75-year-old American woman with no chronic conditions will live 17.3 additional years (that's to more than 92 years old).
This article outlines the top causes of death for adults over the age of 65, starting with the number one cause: heart disease. Using disease prevention strategies, such as eating a healthy diet, quitting smoking, and maintaining a healthy weight, can help you avoid or reduce the impact of some these conditions.
Older adults need about the same amount of sleep as all adults—7 to 9 hours each night. But, older people tend to go to sleep earlier and get up earlier than they did when they were younger.
Women age 85 in the U.S. can expect to live an additional 7.2 years; men an additional 6.1 years.
Leading causes of death among older adults
After age 85, heart disease moves into the number one spot, followed by cancer, Alzheimer's disease, cerebrovascular diseases, and lung diseases.
Research has also emerged that investigates medical procedures for very old adults,4–6 but life expectancy for very old adults is still short in most high-income countries, ranging from around 8 to 10 years for 80-year-olds to 4 to 5 years for 90-year-olds (online Table S1).
The average life expectancy in the United States is 9.1 years for 80-year-old white women and 7.0 years for 80-year-old white men.
Early death, also called premature death, occurs earlier than the average age of death in a population. In the United States, that age is around 75 years old. A lot of illness can happen in the first 74 years of life, yet the majority of early deaths have just a handful of causes.
Boredom, depression, chronic pain and/or nutritional deficiencies can be some of the underlying causes that account for excessive daytime sleeping. Medications can also be a problem.
When are we considered old? For women, the old age threshold is about 73; for men, 70.
According to their internal body clock, most older adults need to go to sleep around 7 p.m. or 8 p.m. and wake up at 3 a.m. or 4 a.m. Many people fight their natural inclination to sleep and choose to go to bed several hours later instead.
While a 30- to 90-minute nap in older adults appears to have brain benefits, anything longer than an hour and a half may create problems with cognition, the ability to think and form memories, according to the study published in the Journal of the American Geriatrics Society.
Hormones: As we age, our bodies secrete less of two important sleep hormones: melatonin and growth hormone. Melatonin is important because changes in the level of this hormone control our sleep cycle. With less melatonin, many older adults feel sleepy in the early evening and wake up in the early morning.
The study, published in the journal Age and Ageing, also found that if the father lived to 90, it did not correlate to increased longevity and health in daughters. However, if both the mother and father lived to 90, the likelihood of the daughter achieving longevity and healthy aging jumped to 38%, researchers said.
According to the SOA, a 65-year-old male today, in average health, has a 55% probability of living to age 85. For a 65-year-old woman, the probability of reaching 85 is 65%.
Your bones, joints and muscles
With age, bones tend to shrink in size and density, weakening them and making them more susceptible to fracture. You might even become a bit shorter. Muscles generally lose strength, endurance and flexibility — factors that can affect your coordination, stability and balance.
From your 60s on, your health risks generally increase. At ages 60 through 80, much of the health problems women are at risk for in their 50s are the same — the risk just increases as time goes on. The risk for heart disease increases significantly for both women and men in their 60s.
At the end of the study, about 16 percent of the men and about 34 percent of the women survived to the age of 90. In fact, the authors found that women who were taller than 5 feet 9 inches were 31 percent more likely to reach 90, compared to those who were under 5 feet 3 inches.
In the United States it is generally considered that a senior citizen is anyone of retirement age, or a person that has reached age 62 or older.
