    THURSDAY, Jan. 21, 2016 (HealthDay News) -- The more than 72,000 Americans who have celebrated 100 birthdays or more are now surviving longer, a new federal report shows.

    Although death rates for centenarians were on the rise between 2000 and 2008, that has since changed, the study found.

    According to researchers at the U.S. Centers for Disease Control and Prevention, death rates for the oldest Americans charted a steady decline between 2008 and 2014. This trend held for both genders and across races and ethnicities, the data showed.

    The leading causes of death for people living to be 100 have also shifted somewhat over the last decade. According to the CDC analysis, heart disease, stroke, flu/pneumonia, cancer and Alzheimer's disease were the top five leading causes of death for the oldest old in 2000.

    However, by 2014, "heart disease was still the leading cause of death, but Alzheimer's disease became the second leading cause, followed by stroke, cancer, and influenza and pneumonia," wrote study author Dr. Jiaquan Xu, of the CDC's National Center for Health Statistics.

    In fact, "the percentage of total deaths from Alzheimer's disease [for centenarians] increased 124 percent between 2000 and 2014," he added.

    In sheer numbers, the "100-plus" club is a growing demographic in the United States. Xu noted that 50,281 Americans were aged 100 or older in 2000, but by 2014 that number had jumped by almost 44 percent, to 72,197.

    Women still comprise about four-fifths of centenarians, the CDC said.

    One expert in geriatric care said there are many factors that have come together to help more and more Americans celebrate three-digit birthdays.

    "In the 19th century there were public health efforts of clean water and sanitation and vaccination science," explained Dr. Maria Torroella Carney, chief of geriatric and palliative medicine at Northwell Health in New Hyde Park, N.Y.

    Then, "in the new millennium, continued vaccination development, health promotion activities, injury prevention -- such as wearing seatbelts and helmets -- have further contributed to increased longevity and life expectancy," she said. More people are also avoiding or quitting smoking, and the air Americans breathe has gotten cleaner, Carney added.
