The national YMCA of the USA was awarded a three-year, $12 million grant from the federal Center for Medicare and Medicaid Innovation to make its diabetes-prevention program available to about 10,000 Medicare patients in 17 communities. Medicare fee-for-service patients pay no additional out-of-pocket cost for the YMCA class and 27 private health plans cover it. For other patients, the fee is charged on an income-based sliding scale that varies by facility and can reach $400, says Matt Longjohn, MD, MPH, the national health officer at YMCA of the USA.

26 million Americans have diabetes, more than 8% of the U.S. population. Researchers estimate that one in three U.S. patients — about 80 million — can be classified as prediabetic either because of their scores on diagnostic blood tests or a combination of age, family history of diabetes and other factors. Patients with prediabetes are two to five times likelier than patients with normal blood glucose to develop type 2 diabetes. Ten percent of prediabetics will become diabetics within seven years, says Ronald T. Ackermann, MD, MPH, associate professor of medicine at Northwestern University Feinberg School of Medicine in Chicago.

A randomized controlled trial of more than 3,000 patients with prediabetes found that patients exposed to an intensive lifestyle-modification program that aimed for 7% weight loss and 150 minutes in weekly physical activity were 58% less likely to develop diabetes than those who received standard lifestyle recommendations and took a placebo pill. During the study’s three-year period, the patients who got the comprehensive lifestyle support in the form of 16 lessons covering diet, exercise and behavior modification avoided diabetes at a rate nearly double that of patients who got the standard advice and took the diabetes drug metformin.

For every seven prediabetics who participated in the lifestyle-modification program, one case of diabetes was avoided, said the study in the Feb. 7, 2002 issue of The New England Journal of Medicine.

Walking to Work Cuts Obesity, Diabetes Risk

Active modes of traveling to work, such as walking or biking, were associated with a lower likelihood of obesity and diabetes, U.K. researchers found.

Compared with using driving a car or taking a taxi, walking to work was associated with a 20% reduced risk of being obese and a 40% reduced risk of diabetes, according to Anthony Laverty, MSc, of the Imperial College London, and colleagues. Those who cycled to work had a 37% lower risk of obesity and a 50% lower risk of diabetes.

One of the downsides of working from home.  So I suppose having my office down the hall from my bedroom increases my risk of obesity and diabetes.

Great.  Pass the chocolate please.

Association Between BMI Measured Within a Year After Diagnosis of Type 2 Diabetes and Mortality

CONCLUSIONS: Patients categorized as normal weight or obese with T2DM within a year of diagnosis of T2DM exhibit variably higher mortality outcomes compared with the overweight group, confirming a U-shaped association of BMI with mortality. Whether weight loss interventions reduce mortality in all T2DM patients requires study.

Could we have another U shaped mortality curve?  Watch that BMI.

AAP Offers First Clinical Guidance for DM2

Up to one in three new diabetes cases diagnosed in people younger than 18 is type 2 diabetes, noted the AAP in its clinical guidelines. Health experts link the growing prevalence of this condition among youths to the rising prevalence of childhood obesity.

Seventeen percent of children and adolescents in the U.S., or 12.5 million people, age 2 to 19 are obese, according to the Centers for Disease Control and Prevention. Since 1980, the prevalence of obesity in this age group has nearly tripled, the CDC says.

PLOS ONE – Height and Weight Bias: The Influence of Time

/ SupremeCmdr / Leave a comment

Abstract

Background

We have previously identified in a study of both self-reported body mass index (BMI) and clinically measured BMI that the sensitivity score in the obese category has declined over a 10-year period. It is known that self-reported weight is significantly lower that measured weight and that self-reported height is significantly higher than measured height. The purpose of this study is to establish if self-reported height bias or weight bias, or both, is responsible for the declining sensitivity in the obese category between self-reported and clinically measured BMI.

Methods

We report on self-reported and clinically measured height and weight from three waves of the Surveys of Lifestyle Attitudes and Nutrition (SLÁN) involving a nationally representative sample of Irish adults. Data were available from 66 men and 142 women in 1998, 147 men and 184 women in 2002 and 909 men and 1128 women in 2007. Respondents were classified into BMI categories normal (<25 kg/m2), overweight (25–<30 kg/m2) and obese (≥30 kg/m2).

Results

Self-reported height bias has remained stable over time regardless of gender, age or clinical BMI category. Self-reported weight bias increases over time for both genders and in all age groups. The increased weight bias is most notable in the obese category.

Conclusions

BMI underestimation is increasing across time. Knowledge that the widening gap between self-reported BMI and measured BMI is attributable to an increased weight bias brings us one step closer to accurately estimating true obesity levels in the population using self-reported data.

The life underwriting implications should be obvious.  Increased weight bias is most notable in the obese.  When in doubt, weigh ’em.

Weight Loss Surgery May Boost Problem Drinking

Almost 10% of patients undergoing bariatric surgery to combat obesity had symptoms of an alcohol use disorder 2 years after surgery, a large prospective cohort study showed.

The prevalence of alcohol use disorders increased from 7.6% before surgery to 9.6% 2 years after the procedure, as reported online in the Journal of the American Medical Association.

East ‘Meats’ West: Diabetes on Rise in China

The Chinese people are eating more food per serving, have more money to buy and eat food — particularly junk food — when they’re not hungry, and engage in less physical activity, Xiaohui said.

He said that many people still eat a traditional Chinese meal, but along with rice and veggies will be more meat, and portions will be bigger as well. In addition, fast-food restaurants such as Kentucky Fried Chicken and McDonald’s are enjoying success at the price of a growing obesity epidemic among children and teens, he said.

Traditional ethnic diets are preferable for your particular ethnicity.  You want fries with that?
