Study: The Longer People Are Obese, the Greater Their Risk for Heart Disease
At a time when obesity rates for both U.S. adults and children are rising, new research indicates that the longer someone is obese, the greater their risk for heart disease. The study appeared in the Journal of the American Medical Association. "Each year of obesity was associated with about a 2 to 4 percent higher risk of subclinical coronary heart disease," said study lead author Jared Reis, an epidemiologist with the U.S. National Heart, Lung, and Blood Institute. "Those with longest duration of both overall obesity and abdominal obesity tended to have the highest risk [for subclinical disease].” Subclinical heart disease includes arterial damage indicated by markers such as calcium buildup on arterial walls, but which “has not yet developed into symptomatic illness,” according to HealthDay. The study is yet more evidence of the need to focus on the prevention and treatment of childhood obesity, according to the researchers. Read more on heart health.
EHRs Would Help Doctors’ Offices Cut Costs Slightly
Doctors’ offices that utilize electronic health records (EHRs) will spend less per patient than offices that use traditional paper records, according to a new study in the journal Annals of Internal Medicine. While the savings is expected to be small—about $5 per patient per month—they will add up over time. With a government commitment of about $30 billion for the widespread adoption of EHRs, the hope is the decrease in inefficiencies, incorrect care and errors will lead to better, cheaper health care. Previous studies have shown conflicting results. Rainu Kaushal, MD, who wrote an editorial that accompanied the study, said that while she does not expected the EHRs to contribute significantly to cost savings, their adoption is still vital. "EHRs may or may not directly contribute to those savings… but without investing in them you cannot achieve new models of healthcare delivery," said Kaushal, director of the Center for Healthcare Informatics and Policy at Weill Cornell Medical College in New York.

No Evidence of Benefits of Community-wide Dementia Screening
New research has found no proof that there are any clinical, economic or emotional benefits to programs that use community-wide screening to identify people with dementia. "We found no evidence that population screening would lead to better clinical or psychosocial outcomes, no evidence furthering our understanding of the risks it entails and no indication of its added value compared to current practice," said author Carol Brayne, a professor of public health medicine from Cambridge Institute of Public Health, in the United Kingdom. The debate over the strategy’s efficacy has been going on for quite some time, with one side noting that there isn’t even a cure for Alzheimer’s disease, and the other noting that as many as half of the people with dementia remain undiagnosed. The researchers, however, did emphasize that family and friends should be aware of the warning signs of dementia so they can help loved ones get treatment. Read more on community health.
