The impact of overweightness and obesity on mortality may have been substantially underestimated in studies that rely on measurement of body mass index (BMI) only at the time of the study. When lifetime highest BMI is used as the criterion, the mortality risk attributable to excess weight increases. These are the major findings of a study in the journal Population Health Metrics, which suggests that risk assessment using only current BMI could be confounded by factors such as recent weight loss due to illness. The study is from Andrew Stokes in the laboratory of Prof Samuel Preston of the University of Pennsylvania.

Large waist circumference leads to lower life expectancy even among people with healthy body mass index (BMI) according to the results of a new study in Mayo Clinic Proceedings. The study from researchers in the USA, Australia, Sweden, Norway and Finland found a linear association between waist circumference and all-cause mortality.

A recent study led by Boston University School of Medicine (BUSM) shows that "practice may make perfect" when it comes to caring for patients with severe sepsis. The study showed that patients admitted to academic medical centers that care for more patients with severe sepsis have significantly lower mortality rates than patients cared for at academic medical centers with lower volumes of sepsis patients. Additionally, the superior outcomes at high volume centers were achieved at similar costs compared to the lower volume medical centers.

A new study published in the American Journal of Preventive Medicine gives new insight into the geographic variation in drug poisoning mortality, with both urban centers and rural areas showing a large increase in death rates. While previous studies have looked at drug poisoning related deaths in broad strokes, this is the first study to examine them on the county level across the entire U.S.

Marriage may not always be as beneficial to health as experts have led us to believe, according to a new study. Researchers made two discoveries that explain why: First, marriage provides less protection against mortality as health deteriorates, even though it does seem to benefit those who are in excellent health. Secondly, married people tend to overestimate how healthy they are, compared to others.

A large study of nearly half a million older adults followed for about 12 years revealed a clear trend: as coffee drinking increased, the risk of death decreased. Study author Neal Freedman, PhD, MPH, National Cancer Institute, discusses the significance of these findings and the potential links between coffee drinking, caffeine consumption, and various specific causes of disease.
