Chronic Diseases
Chronic diseases are diseases of long duration and generally slow progression. Chronic diseases, such as heart disease, stroke, cancer, chronic respiratory diseases and diabetes, are by far the leading cause of mortality in the world, representing 60% of all deaths. Chronic diseases generally cannot be prevented by vaccines or cured by medication, nor do they just disappear. As of November 24, approximately 1,520,858 people have died from chronic disease this year.
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.
? Obesity has become a major health concern. 1 in every 3 adults is obese and almost 1 in 5 youth between the ages of 6 and 19 is obese (BMI ? 95th percentile of the CDC growth chart).
? About one-fourth of people with chronic conditions have one or more daily activity limitations.
? Arthritis is the most common cause of disability, with nearly 19 million Americans reporting activity limitations.
? Diabetes continues to be the leading cause of kidney failure, nontraumatic lower-extremity amputations, and blindness among adults, aged 20-74.
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.
These causes are expressed through the intermediate risk factors of raised blood pressure, raised glucose levels, abnormal blood lipids (particularly low density lipoprotein - LDL cholesterol), and overweight (body mass index ?25 kg/m2) and obesity (body mass index ?30 kg/m2). The major modifiable risk factors, in conjunction with the non-modifiable risk factors of age and heredity, explain the majority of new events of heart disease, stroke, chronic respiratory diseases and some important cancers. The relationship between the major modifiable risk factors and the main chronic diseases is similar in all regions of the world.
? 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.
? More than 43 million American adults (approximately 1 in 5) smoke.
? 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.
? Nearly 45% of high school students report consuming alcohol in the past 30 days, and over 60% of those who drink report binge drinking (consuming 5 or more drinks on an occasion) within the past 30 days.
? A large number of studies provide strong evidence that drinking alcohol is a risk factor for primary liver cancer, and more than 100 studies have found an increased risk of breast cancer with increasing alcohol intake. The link between alcohol consumption and colorectal (colon) cancer has been reported in more than 50 studies.
Chronic diseases have a long course of illness. They rarely resolve spontaneously and they are generally not cured by medication or prevented by vaccine. Chronic diseases - such as heart disease, cancer, and diabetes - account for 7 of every 10 deaths and affect the quality of life of 90 million Americans. Chronic disabling conditions cause major limitations in activity for more than 1 of every 10 Americans or 25 million people. Although chronic diseases are among the most common and costly health problems, they are also among the most preventable. Adopting healthy behaviors such as eating nutritious foods, being physically active, and avoiding tobacco use can prevent or control the devastating effects of these diseases.
