Osteoarthritis : Risk Factors

Obesity is an abnormal accumulation of body fat, usually 20% or more over an individual's ideal body weight. Obesity is associated with increased risk of illness, disability, and death. The branch of medicine that deals with the study and treatment of obesity is known as bariatrics. As obesity has become a major health problem in the United States, bariatrics has become a separate medical and surgical specialty.

Obesity is a term used to describe body weight that is much greater than what is considered healthy. If you are obese, you have a much higher amount of body fat than lean muscle mass. Adults with a body mass index (BMI) greater than 25 but less than 30 are considered overweight. Adults with a BMI greater than 30 are considered obese. Anyone more than 100 pounds overweight or with a BMI greater than 40 is considered morbidly obese.

Obesity , defined as a body mass index of 30 or greater, is an epidemic in the United States and other industrialized nations, and it is rapidly becoming one in developing nations. As countries transition to westernized lifestyles, obesity tends to increase. Obesity rates vary from as little as 2 percent in some Asian countries to as much as 75 percent in some Pacific nations. There are more than 300 million obese persons in the world, and more than 750 million overweight persons. In the United States, 34 percent of adults are over-weight and 30.5 percent are obese. Between 1980 and 2000, the percentage of overweight children ages six to eleven doubled, from 7 percent to 15 percent, and the percentage of overweight adolescents ages twelve to nineteen tripled, from 5 percent to 16 percent (Ogden, et al.). In Europe, the thinnest country is Sweden, with about 10 percent obesity, while the fattest is Lithuania, with about 79 percent obesity. The sad fact is the prevalence of obesity appears to be increasing in all countries. An obese person has a 50 to 100 percent increased risk of premature death compared to someone of normal weight. In the United States, more than 300,000 deaths a year are attributable to obesity. Obesity is associated with type 2 diabetes , coronary heart disease , stroke , hypertension , elevated blood cholesterol , some cancers (e.g., colon, endometrial, kidney, gallbladder, and postmenopausal breast cancer ), osteoarthritis , gallbladder disease, and respiratory disease. In addition, obesity is often associated with discrimination and prejudice, causing some obese people to suffer poor self-esteem and reduced quality of life. The health care costs attributable to obesity exceed $100 billion a year in the United States, more than 6 percent of the total health care costs.

obesity increases the risk for illness from 30 serious medical conditions, including diabetes, heart disease and several types of cancer.

Term describing a condition where the ratio of body fat to total body mass is higher than accepted norms. Obesity is a relative term used to describe the condition where the ratio of body fat, which is measurable, to total body mass is higher than the accepted norm. {Obesity and overweight are often used interchangeably, but their technical definitions are different. Overweight refers to an excess of body weight that includes all tissues—fat, bone, and muscle. Obesity refers specifically to an excess of body fat.) Body fat is about 15% of total body mass for the normal adult male and about 20-25% for the normal adult female. A general rule of thumb is that an individual is probably obese when his or her weight exceeds the maximum weight on standardized height and weight charts by more than 20%. However, during childhood and adolescence, when the body is growing and developing, the proportion of body fat is slightly higher than for a mature adult. In addition, the proportion of body fat fluctuates during various stages of growth. The percent of U.S. children who are overweight is estimated to be between 20-30%, but there is no firm definition of obesity for children and adolescents. The body mass index (BMI) and average weight-for-height charts provide general guidelines. Pediatricians and parents should evaluate an individual child's weight in the context of his stage of growth, level of physical activity, and general dietary habits. Richard P. Troiano, a researcher at the Centers for Disease Control and Prevention, encourages parents and physicians to observe children and adolescents in their environment over time, and cautions against making weight a disease. Adults should help children see the relationship between eating and exercise choices and weight.

Bariatric surgery, which helps extremely obese people lose weight by reducing the size of the stomach and intestines, carries a higher risk of death than previously believed, new research shows. Three studies, published October 19 in the Journal of the American Medical Association, found death rates of 3% to 5% for middle-aged adults and more than twice that high for patients 65 to 74, the Associated Press (AP) reported. Among patients 75 or older, 40% of the women and half of the men died, the AP story said.

What is responsible for obesity, how to treat it.At one time it was commonly believed that overweight and obese people were compulsive eaters, anxious, depressed, under stress, or trying to compensate for inadequate upbringing, family conflict, or other deficiencies in their lives. But since then, when almost everyone seems to be getting heavier and obesity has become a national political issue, both experts and the public are turning away from the idea that weight gain is a personal emotional problem. Instead the trend toward obesity has become a subject for biologists and sociologists, regarded as the physical consequence of a general social condition. It’s become less clear what role psychotherapists and other mental health professionals should play in managing the problem.

The American Diabetes Association estimates at least 20.1 million people in the United States have pre-diabetes. Pre-diabetes means having a blood sugar level that is higher than normal, but not yet persistently high enough to be considered type 2 diabetes. By taking steps to control your blood sugar, you can delay or prevent type 2 diabetes from developing.

More than 19 million Americans have type 2 diabetes, and millions more have a condition that puts them at high risk for developing it.

Each overweight or obese American spends $700 more a year on medical bills than trim neighbors, one expert says.

With two out of three Americans overweight or obese, it's become a community problem. The solution requires cooperation from public and private institutions.

Obesity has become a public health crisis in the United States, in part, because Americans are consuming more calories than they did 30 years ago. A large part of that increase in consumption can be pinned on a greater use of foods prepared away from home -- those ready-to-eat items available at restaurants, grocery store food counters and fast-food eateries.

Children whose parents are overweight or obese are at higher risk for becoming obese themselves, studies have shown. One study, in the New England Journal of Medicine, found that for a child under 10, having an obese parent more than doubled the child's risk for becoming an obese adult.

Obesity is the most common health problem facing children, child health experts say. More than 30 percent of children and teens are overweight, and 15 percent are obese.

True or false? Most overweight people got that way because they're self-indulgent weaklings without the will power to say no to super-sized french fries and fudge-slathered ice cream.

We've all heard warnings, yet many of us keep gaining weight. More than half of American adults are overweight or obese, says the Centers for Disease Control and Prevention (CDC).

Many obese adults don't believe they are obese. A small survey (104 adults ages 45 to 64 were polled) found that 71% of normal-weight people placed themselves in the correct weight category, as did 73% of overweight people. However, only 15% of obese people identified themselves as obese. The Associated Press reported April 9 on the survey, done by the U.S. Centers for Disease Control and Prevention (CDC). According to the CDC, an adult who is 5 feet 10 inches tall is overweight at 174 pounds and obese at 209 pounds.

Experts in one study say the study shows the limitations of the Body Mass Index (BMI) as a measure of obesity, especially because it doesn't account for weight that is muscle rather than fat. A study of 90,000 U.S. women, described in the second article, says the risk of death jumps sharply for extremely obese women -- those at least 90 pounds overweight.

The American College of Obstetricians and Gynecologists (ACOG) is warning that obesity during pregnancy increases the risk of several complications, including high blood pressure, a serious condition called preeclampsia and gestational diabetes. The ACOG opinion, published in the September issue of Obstetrics & Gynecology, says obese women also are more likely to miscarry, to need a Caesarean section, and to have excessive bleeding and infection after a Caesarean section. Babies of obese women are more likely to be stillborn, be born prematurely and have spinal cord abnormalities called neural tube defects. The risks affect women with a body mass index (BMI) of 25 to 30, and are even higher for women with a BMI of more than 30.

Experts are challenging a recent, widely reported study that suggested being overweight is not associated with early mortality.

Women's health differs from men's health, and not just with respect to reproduction. To understand and examine these differences appropriately, the variables of sex and gender are each relevant. In general, sex refers to biological, anatomical, physiological, and hormonal variations that, on average, distinguish females and males. By contrast, gender refers to the differences between men and women, boys and girls, that stem from how behaviors, abilities, responsibilities, and overall values are ascribed differentially to males and to females in a society. Sometimes separately, but more often through their interactions, sex and gender are important determinants of health. For instance, there are sex-linked diseases (e.g., hemophilia) that only rarely and under exceptional circumstances affect women. There are also sex-specific cancers (e.g., of the prostate [men] and of the ovaries [women]), as well as specific conditions that, because of their biological exclusivity to males or females, can only occur in one or other sex (e.g., pregnancy-related conditions in women; testicular disorders in men). Generally, however, observed differences in the frequency of some health outcome between women and men do not reflect a sex (biologic) difference. Rather, most differences derive from a complex set of interactions between sex (biology) and gender (roles and expectations). Every society has its own economic, social, cultural, and political arrangements that make being a woman different from being a man. The gender norms and expectations applied to women and to men that derive from these arrangements vary from place to place, change overtime, and are always affected by other features (e.g., age, class, ethnicity, sexual orientation, ability) that are attached to an individual. As a result of the gender differences assigned to them, individuals will experience their lives differently according to whether they are defined as male or female. Accordingly, women and men will have different exposures to different risks, different responses to the same exposures, different patterns to seeking treatment, and different needs for and responses to public health programs. These all contribute to differences in the frequency and distribution of diseases between them. Consequently, to understand and respond to most human health and sickness issues, clarifying the interaction between sex-linked factors and gender-based factors is critical; the expectations, norms, and stereotypes associated with the roles of men and women play out in their health, strongly influencing symptoms, treatments, and policies. As an example, consider the relation of work to health. Much research has shown that underemployment and lack of control over work situations or job demands are associated with increased levels of stress and poor health. These employment and working conditions differ according to gender, and women in the paid workforce in North America are more likely than men to have undervalued and underpaid jobs in the service sector, to work part-time, to have interruptions of their careers because of family responsibilities, and to experience high-demand, low-control conditions at work. All these factors influence their risks for (exposure to) disease, what they do when ill, how health care professionals respond to and treat them, and what public policies of work-related health promotion and health protection are developed. Thus, to examine the relation of work to health without accounting for the influence of gender would be to ignore how women may be exposed to health-damaging agents unlike those their male colleagues face; how they may have less access to private health care (United States) or necessary medications that must be paid for out-of-pocket (United States and Canada); and how they may have reduced opportunities to attend health programs, such as screening programs, because after-work hours are filled with child-care duties more often for women than for

Starting at what is commonly called middle age, operations of the human body begin to be more vulnerable to daily wear and tear; there is a general decline in physical, and possibly mental, functioning. In the Western countries, the length of life is often into the 70s. The upward limit of the life span, however, can be as high as 120 years. During the latter half of life, an individual is more prone to have problems with the various functions of the body and to develop any number of chronic or fatal diseases. The cardiovascular, digestive, excretory, nervous, reproductive and urinary systems are particularly affected. The most common diseases of aging include Alzheimer's, arthritis, cancer , diabetes, depression, and heart disease.

In general, only about three percent of the elderly living independently in the community will experience depression. That figure increases to around 20 to 30 percent of persons in nursing homes or with chronic illnesses like emphysema, heart disease or diabetes.

Aging is the process of growing older, a process that includes physical changes and, sometimes, mental changes. "The aged" refers to elderly people, those who have reached an advanced age.

Through the daily grapevine of popular culture, we get the message over and over that young is better than old. But new research contradicts these age-old stereotypes. Indeed, studies suggest that the older you get, the happier you become.

This term is used by demographers when referring to an increase over time in the proportion of older persons in the population. It does not necessarily imply an increase in life expectancy, that "people are living longer that they used to," or that they are dying on average at older ages, although these phenomena are usually observed in association with aging of the population. From the demo-graphic perspective, the principal determinant of aging in the population is a decline in the birth rate. When fewer children are born than in earlier years, the consequence is a decline in the proportion of younger persons, and it necessarily follows that there is an increase in the proportion of older persons. The proportion is further weighted toward older persons by improved survival rates from conditions that can cause death in early life, that is, in infancy and childhood and among younger adults. In the industrialized nations, a more recent phenomenon has been an increase in life expectancy that has accompanied improved survival rates, and this, of course, contributes further to the increased proportion of older persons. However, if birth rates remain high, there is also an increase in the numbers, and therefore in the proportion, of infants and children in the population. This happened in many industrialized nations after World War II, during the "baby boom" period, roughly 1946 to 1960. There was a secondary surge in birth rates when the children born during that period reached peak reproductive ages (the echo of the baby boom) in the 1980s and 1990s. The baby boom and its echo temporarily retarded and in some nations even briefly reversed the long-term trend toward smaller families. This trend began in the Western industrial nations before the 1920s and continued through the 1930s, aggravated by the Great Depression, but persisting through good times as well as bad. Although it is true that in the past, declining birth rates were primarily responsible and reductions in mortality rates played little part in the process of aging the population, in the future it can be expected that increases in life expectancy will contribute more to the process. Little further reduction in mortality rates in the first half of life can be expected to occur, so increased life expectancy, or mortality rate reduction, in the second half of life, from age forty-five onward, is beginning to exert more influence on the structure of the population (the shape of the population pyramid). This too is contributing to an increase in the proportion of older persons in the population, and over the coming decades, other things being equal, this will play an increasingly prominent role in the process.

It's never easy to ponder death, whether you're facing the demise of a loved one or the end of your own life. But taking some time to think and plan ahead for those final hours or days can be a future blessing for your family and others close to you. Most people want a say in all life's important decisions. The same should be true regarding decisions surrounding death, such as what kind of medical treatment you receive. But what if you're unable to make your decisions or wishes known? Say, for example, you are unconscious and can't speak or hear. Unless you have spoken with your loved ones and taken certain legal actions, there may be confusion and stress over what those decisions will be and who can make them for you.
