Just recently the BJSM published the Consensus Statement from the first Economics of Physical Inactivity Consensus (EPIC) Conference. This consensus summarises the outcome of discussions as they apply to the health and economic burden of physical inactivity, held at the EPIC Conference in 2011 Vancouver. Specifically, the consensus (1) details existing evidence on effective physical inactivity prevention strategies; (2) introduces economic evaluation and its role in health policy decisions; (3) discusses key challenges in establishing and building health economic evaluation evidence (including accurate and reliable costs and clinical outcome measurement) and (4) provides insight into interpretation of economic evaluations in this critically important field.

This manuscript describes a population based cross-sectional study derived from the HUNT study in Norway. The HUNT study measured in a sample 48,882 adults aged 20 years or older, amongst other outcomes, waist circumference, BMI, total cholesterol, HDL cholesterol, blood pressure, non-fasting glucose, gamma glutamyltransferase (GGT) and triglycerides. Adjusted multiple regression models were used to test for associations between these biomarkers and self-reported total sitting time, TV-viewing and leisure-time computer use.
