Understanding Chronic Disease

What is Chronic Disease? (Center for Managing Chronic Disease)

Chronic Disease is a long-lasting condition that can be controlled but not cured. Chronic illness affects the population worldwide. As described by the Centers for Disease Control, chronic disease is the leading cause of death and disability in the United States. It accounts for 70% of all deaths in the U.S., which is 1.7 million each year. Data from the World Health Organization show that chronic disease is also the major cause of premature death around the world even in places where infectious disease are rampant. Although chronic diseases are among the most common and costly health problems, they are also among the most preventable and most can be effectively controlled.

Chronic Diseases and Health Promotion (Centers for Disease Control and Prevention)

Chronic diseases – such as heart disease, stroke, cancer, diabetes, and arthritis – are among the most common, costly, and preventable of all health problems in the U.S.

Chronic Diseases are the Leading Causes of Death and Disability in the U.S.

  • 7 out of 10 deaths among Americans each year are from chronic diseases. Heart disease, cancer and stroke account for more than 50% of all deaths each year.1
  • In 2005, 133 million Americans – almost 1 out of every 2 adults – had at least one chronic illness.2
  • Obesity has become a major health concern. 1 in every 3 adults is obese3 and almost 1 in 5 youth between the ages of 6 and 19 is obese (BMI ≥ 95th percentile of the CDC growth chart).4
  • About one-fourth of people with chronic conditions have one or more daily activity limitations.5
  • Arthritis is the most common cause of disability, with nearly 19 million Americans reporting activity limitations.6
  • Diabetes continues to be the leading cause of kidney failure, nontraumatic lower-extremity amputations, and blindness among adults, aged 20-74.7
  • Excessive alcohol consumption is the third leading preventable cause of death in the U.S., behind diet and physical activity and tobacco. 8

Four Common Causes of Chronic Disease

Four modifiable health risk behaviors—lack of physical activity, poor nutrition, tobacco use, and excessive alcohol consumption—are responsible for much of the illness, suffering, and early death related to chronic diseases.

  • More than one-third of all adults do not meet recommendations for aerobic physical activity based on the 2008 Physical Activity Guidelines for Americans, and 23% report no leisure-time physical activity at all in the preceding month.9
  • In 2007, less than 22% of high school students10 and only 24% of adults11 reported eating 5 or more servings of fruits and vegetables per day.
  • More than 43 million American adults (approximately 1 in 5) smoke.12
  • In 2007, 20% of high school students in the United States were current cigarette smokers.13
  • Lung cancer is the leading cause of cancer death, and cigarette smoking causes almost all cases. Compared to nonsmokers, men who smoke are about 23 times more likely to develop lung cancer and women who smoke are about 13 times more likely. Smoking causes about 90% of lung cancer deaths in men and almost 80% in women. Smoking also causes cancer of the voicebox (larynx), mouth and throat, esophagus, bladder, kidney, pancreas, cervix, and stomach, and causes acute myeloid leukemia.14
  • Excessive alcohol consumption contributes to over 54 different diseases and injuries, including cancer of the mouth, throat, esophagus, liver, colon, and breast, liver diseases, and other cardiovascular, neurological, psychiatric, and gastrointestinal health problems.15
  • Binge drinking, the most dangerous pattern of drinking (defined as consuming more than 4 drinks on an occasion for women or 5 drinks for men) is reported by 17% of U.S. adults, averaging 8 drinks per binge.16
