Background: Multivitamins are the most commonly used supplement in the developed world. Recent epidemiological findings suggest multivitamin use increases the risk of mortality. Objectives: We aimed to determine whether multivitamin-multimineral treatment, used for primary or secondary prevention, increases the risk of mortality in independently living adults. Methods: We performed a meta-analysis of randomized, controlled trials. Multiple electronic databases were systematically searched...

Objective: To investigate the association between periodontitis and mortality from all causes in a prospective study in a homogenous group of 60-70 year-old Western European men. Methodology: A representative sample of 1400 dentate men, (mean age 63.8 SD 3.0 years), drawn from the population of Northern Ireland, had a comprehensive periodontal examination between 2001 and 2003. Men were divided into thirds on the basis of their mean periodontal attachment loss (PAL). The primary endpoint,...

Background: Low vitamin D status may increase mortality risk. OBJECTIVE: We used nonparametric ("highest compared with lowest" categories) and parametric (>2 categories) statistical models to evaluate associations of 25-hydroxyvitamin D [25(OH)D] serum concentrations and mortality in observational studies among general populations. DESIGN: We searched PubMed, EMBASE, Web of Science, and reference lists for relevant articles. We included studies that contained data on relative risks (RRs)...

Click to view article publication Social Relationships and Mortality Risk: A Meta-analytic Review Social relationships are linked to improved survival Individuals with adequate social relationships have a 50% greater likelihood of survival compared to those with poor or insufficient social relationships. The magnitude of this effect is comparable with stopping smoking and exceeds many well known risk factors for mortality such as obesity and physical inactivity. These are the main...
