What is Obesity? According to the National Institute of Health: Obesity is a complex, chronic disease that develops from multiple genetic and the environmental factors. It involves the integration of social, behavioral, cultural, physiological, metabolic and genetic factors."
Indiana Statistics Indiana has adult obesity rates of 30.8 percent, ranking it the 6th heaviest in the nation, according to a new report by Center for Disease Control.
Epidemiological Reviews - May 2007, Wang & Others 58 million Americans are overweight 40 million Americans are obese 3 million Americans are morbidly obese Eight out of 10 Americans over 25 years old are overweight By 2015, 41% of Americans will be obese
Economic Impact of Obesity The estimated annual cost of overweight and obesity in the U.S. is $122.9 billion. Services for obesity-related diseases and conditions $64 billion: Direct health care costs related to: preventive, diagnostic, and treatment Indirect costs $58.5 billion: The value of wages lost by people unable to work and the value of future earnings lost by premature death. Obesity related conditions result in $39.3 million in lost workdays each year.
Economic Impact of Obesity Obesity accounts for 9 percent of national health care expenditures. The estimated cost of obesity in a hypothetical 1-millionmember health plan is $29 per member per month. Over a nine-year period, overweight (body mass index (BMI) between 25 and 29.9) spend 37 percent more on prescription drugs; obese (BMI >30) spend twice as much. Employees with a BMI > 40 had twice as many workers compensation claims as employees at their recommended weight.
Life Expectancy The risk of death for people with a BMI >= 25 at age 50 is 20 percent to 40 percent higher than those with a BMI of less than 25. Obesity was associated with double the mortality risk in men and a 60 percent increase in women compared with those of normal weight.
What is Obesity Obesity is the over accumulation of fat that exceeds the body s skeletal and physical standards. According to the National Health (NIH), an increase in BMI of more than 30 is the point at which excess weight becomes a health risk
BMI and Disease Risk Body mass index (BMI) using the following equation: An adult who has a BMI between 25 and 29.9 is considered overweight. An adult who has a BMI of 30 or higher is considered obese and > 40 is considered morbidly obese. Waist Circumference is also an important measure in determination of disease risk http://www.nhlbisupport.com/bmi/
BMI and Disease Risk BMI is only one factor related to risk for disease. Two other predictors: The individual s waist circumference (because abdominal fat is a predictor of risk for obesity-related diseases). Other risk factors the individual has for diseases and conditions associated with obesity (for example, high blood pressure or physical inactivity). Fat stored around the abdomen and waist (also called, central adiposity, intra-abdominal fat, or central obesity) is a predictor of weight-related diseases.
Waist Circumference Apple Shape: Store excess body fat around their stomach and abdomen Increased risk of weightrelated disorders and need to pay more attention to normalizing their weight. Typically men OR postmenopausal women Healthy waist measurement for a male is less than 40 inches provided your BMI is less than 25. Pear Shape: Tend to gain weight on buttocks and thighs. Typically women Healthy waist measurement for a female is less than 35 inches provided your BMI is less than 25.

Archives of Internal Medicine, April 2007 Ostbye & Others Obesity and Workers Compensation Results from the Duke Health and Safety Surveillance System Studied the relationship between BMI and the number and types of workers compensation claims, associated costs and lost workdays 11,728 health care and university employees Ostbye, T MD, PhD; Dement, JM, PhD; Krause, KM, MA Archives of Internal Medicine; Arch Intern Med. 2007;167(8):766-773.
Results
Conclusion The researchers found that workers with a BMI greater than 40 had: 11.65 claims per 100 workers, compared with 5.8 claims per 100 in workers within the recommended range. In terms of average lost days of work, the obese averaged 183.63 per 100 employees, compared with 14.19 per 100 for those in the recommended range. The average medical claims costs per 100 employees were $51,019 for the obese and $7,503 for the non-obese. The body parts most prone to injury among obese workers were the lower extremity, wrist or hand, and back. The most common causes of these injuries were falls or slips, and lifting.
Implications As obese workers continue to gain weight and their BMI approaches 40, their strength does not keep up with their weight gain. Making them more susceptible to injury What impact does this have on the morbidly obese worker s ability to safely perform the essential functions of the job?

Implications of Obesity Obesity increases the risk of many diseases and health conditions, including: Hypertension Dyslipidemia Type 2 Diabetes Coronary heart disease Stroke Gallbladder disease Sleep apnea and respiratory problems Some cancers (endometrial, breast, and colon) Osteoarthritis (a degeneration of cartilage and its underlying bone within a joint) Orthopedic problems and Impaired mobility
Orthopedic Issues in Obesity Individuals with a BMI < 40 have an increased incidence of work related injury (acute & chronic) Specifically rotator cuff tears, low back pain, lumbar disk herniation and osteoarthritis Increased recovery time following injury Increased risk for post-surgical complications Increased risk for heat related illness
Orthopedic Issues in Obesity Being only 10 pounds overweight increases the force on the knee by 30-60 pounds with each step. Therefore, a force of ~ three to six times one's body weight is exerted across the knee while walking. Increased joint loading accelerates the breakdown of cartilage.
Osteoarthritis Obesity is a known risk factor for the development and progression of knee OA and other weight bearing joints Obese adults are up to 4x more likely to develop knee osteoarthritis than normal weight adults. 35% of adults with diagnosed arthritis are obese compared to only 21% of those without arthritis. The most modifiable risk factor for development and progression of OA is obesity. NHI: 2007-2009
Osteoarthritis by the Numbers 600,000 Americans had knee replacements in 2011. By 2030 that number will be 3.5 million. Cost of a knee replacement: $24,000 (not counting diagnostics or rehabilitation). Lost work time following knee replacement: Sedentary work: 6-12 weeks Medium work: 6-12 months Heavy work: not recommended Replaced knees last an average of 15 years in normal weight individuals.
Knee Osteoarthritis Incidence In the Framingham study, Felson and colleagues noted: Among women with (BMI) > 25, weight loss was associated with a significantly lower risk of knee OA. For a woman of normal height, for every 11 lb weight loss (approximately 2 BMI units), the risk of knee OA dropped > 50%. Conversely, a comparable weight gain was associated with an increased risk of later developing knee OA (odds ratio 1.28 for a 2 BMI weight gain).
Knee Osteoarthritis In elderly persons, if obese men (i.e., BMI greater than 30) lost enough weight to fall into the overweight category (BMI 26-29.9) and men in the overweight category lost enough weight to move into the normal weight category (BMI less than 26), knee OA would decrease by 21.5%. Similar changes in weight category by women would result in a 33% decrease in knee OA. Conclusion: Even small amounts of weight loss reduce the risk of developing knee OA. Felson et al
Total Joint Replacement Outcomes Thomas Turgeon, MD, assistant professor of orthopaedic surgery at the University of Manitoba, Canada, presented a study of 1,247 patients of varying weight who underwent primary hip replacement. He and his research team found highly obese patients: 2.3 times more likely to stay in the hospital more than five days 2.6 times more likely to be discharged to a skilled nursing facility (SNF).
Total Knee Replacement Outcomes The conclusion of the study: Obese patients take more time in the operating room. Obese patients are more likely to need expensive MUA with greater incidence in women Obesity limits a patient's range of motion (ROM), Prolongs recovery Extends the need for physical therapy after total knee replacement surgery Geoffrey H. Westrich, MD, The Hospital for Special Surgery in New York City,
Joint Replacement Outcomes Using a database of nearly 1 million Americans who underwent major joint replacement surgery, a team led by researchers at Duke University Medical Center have determined: Surgical patients with diabetes, hypertension or obesity were significantly more likely to suffer post-operative complications. Of three conditions that the researchers studied, obesity conferred the highest risk of post-operative complications and the need for additional post-discharge care. Clinical Orthopaedics and Related Research
Duke Study Outcomes Specifically, in their analysis of patients undergoing hip, knee or shoulder replacement surgery, the researchers found: 3.7 percent of obese patients experienced inhospital complications, compared to 2.6 percent for non-obese patients. For patients with hypertension, the rates were 2.8 percent versus 2.6 percent, For patients with diabetes, the ranges were 2.9 percent versus 2.6 percent. Journal Clinical Orthopaedics and Related Research
Additional Outcomes The likelihood of a "non-routine" discharge from the hospital was 30 percent higher for diabetics and 45 percent higher in obese patients For patients with diabetes who were also obese, the likelihood rose to 75 percent. Non-routine discharges are those to another facility where further care is necessary, such as short-term hospitals, intermediate care facilities or home health care.
Additional Orthopedic Outcomes: Research shows that Obesity: Is associated with a substantially higher risk for infection in women, led to more dislocations (with a greater increase in women) Resulted in more revisions due to septic loosening (caused by infection). After five years, outcomes for 635 hips in non-obese patients and 183 hips in obese patients were evaluated. Obese women, but not obese men, reported moderately lower functional outcomes and slightly less satisfaction, mostly due to a higher incidence of complications.
Rehabilitation in Obesity Understanding the role of rehabilitation in the treatment of joint replacement patients has been studied and found to improve outcomes. Exercise participation prior to total joint arthroplasty dramatically reduces the odds of inpatient rehabilitation Among THR patients, exercise intervention was associated with improvements in preoperative function score. Exercise participation increased muscle strength preoperatively, whereas the control patients had essentially no change in strength. The authors concluded that a 6-week pre-surgical exercise program can safely improve preoperative functional status and muscle strength levels in patients undergoing THR. Rooks et al

Handheld showerhead Long-handled scrub brush Raised Commode seat Transfer Bench Wheelchair Walker Quad cane Foot stool *500-1000 lb capacity for Bariatric needs **Typical load capacity is 250-300 lbs
Bariatric Patient Equipment When the resulting BMI is greater than 38, there is a possible need for special bariatric equipment. If the BMI is greater than 39.9, the patient is considered morbidly obese. For example: a 5 8 tall, 255 lb person has a BMI= 39). The process of identifying equipment needs includes the following: Create a protocol for identifying the bariatric patient at point-ofcontact areas, such as pre-admission testing, emergency, etc. Develop a method to procure or rent necessary equipment if it is not available in-house Identify and label in-house equipment with weight capacities.
