Sedentary Behavior Is Linked to Shorter Life Expectancy

Sitting daily for less than 3 hours and watching TV for less than2 hours extends life expectancy by an estimated 1 to 2 years.

Adverse effects of sedentary behaviors on health outcomes are well known, but what are the effects on life expectancy? Investigators used data from five prospective cohort studies and from the National Health and Nutrition Examination Survey (NHANES) to estimate the effect of sitting and television viewing on life expectancy at birth in the U.S. population.

What's the Optimal HbA1c Level in Elders?

In an observational study, glycosylated hemoglobin between 8% and 9% was best.

Experienced clinicians have long recognized that tight glycemic control can be perilous in frail older patients with type 2 diabetes. Now, an observational study addresses that concern. Researchers in San Francisco studied 367 community-dwelling, older patients (mean age, 80) with diabetes who participated in a comprehensive adult day-care program and were unable to live independently.

Diabetes + HIV = A Double Whammy for CKD

Diabetes and HIV infection each contribute to progressive chronic kidney disease, but the two factors together are especially detrimental.

Chronic kidney disease is responsible for an increasing burden of disease in HIV-infected patients, driven in part by an increasing prevalence of diabetes in this population. In the present study, researchers evaluated the relative contributions of HIV infection and diabetes to the risk for chronic kidney disease.

Blood Sugar, Blood Pressure and Cholesterol

People with diabetes are more often achieving recommended targets for blood sugar, blood pressure, and cholesterol, but fewer than 20% are meeting all three, according to new data from an ongoing national health survey.

Doctors treating people with diabetes look at three different goals called the ABCs: A1c level (from HBA1c for diabetes), blood pressure, and cholesterol. People with diabetes who achieve these goals lower their risk of health complications and death.
