A study in the Sept. 1 issue of the journal SLEEP found an elevated risk of death in men, but not for women, with a complaint of chronic insomnia and an objectively measured short sleep duration. The results suggest that public health policy should emphasize the diagnosis and appropriate treatment of chronic insomnia.

A majority of adults in California are obese or overweight, and more than 2 million have been diagnosed with diabetes, according to a new study from the UCLA Center for Health Policy Research. Both conditions – which are related to each other as well as to heart disease – increased significantly in just six years, with the prevalence of diabetes alone jumping nearly 26 percent between 2001 and 2007.

Gene variants associated with an increased risk for type-1 diabetes and rheumatoid arthritis may confer previously unknown benefits to their human carriers, say researchers at the Stanford University School of Medicine. As a result, the human race may have evolved in the recent past to be more susceptible, rather than less, to some complex diseases, they conclude. The results were published Aug. 17 in Public Library of Science ONE. Check the end of this report for a link to download this open access article.

Overweight American children and adolescents have become fatter over the last decade, according to researchers at the Johns Hopkins Bloomberg School of Public Health and National Institute on Aging (NIA). They examined adiposity shifts across socio-demographic groups over time and found U.S. children and adolescents had significantly increased adiposity measures such as body mass index (BMI), waist circumference (WC) and triceps skinfold thickness (TST). The increases in adiposity were more pronounced in some sex-ethnic groups such as black girls.

Anthony Norman, a leading international expert in vitamin D, proposes worldwide policy changes regarding people’s vitamin D daily intake amount in order to maximize the vitamin’s contribution to reducing the frequency of many diseases, including childhood rickets, adult osteomalacia, cancer, autoimmune type-1 diabetes, hypertension, cardiovascular disease, obesity and muscle weakness.

A study by researchers at NYU Langone Medical Center have found that obese adolescents with type 2 diabetes have diminished cognitive performance and subtle abnormalities in the brain as detected by Magnetic Resonance Imaging (MRI). Identification of cognitive impairments as a complication of type 2 diabetes emphasizes the importance of addressing issues of inactivity and obesity, two important risk factors for the development of the disease among the young. The study appeared online in the journal Diabetologia on July 30, 2010.

Resveratrol – found in red wine, grapes, blueberries, peanuts and other plants – stops out-of-control blood vessel growth in the eye, according to vision researchers at Washington University School of Medicine in St. Louis. The discovery has implications for preserving vision in blinding eye diseases such as diabetic retinopathy and age-related macular degeneration, the leading [...]

Children are more likely to watch high levels of television if their parents do, but parents do not need to be physically active to help their children to be active, a new study has found. The paper, Parent and child physical activity and sedentary time: Do active parents foster active children? by Dr Russell Jago [...]
