Genetic analysis of physical activity in twins
TL;DR: In the present exploratory study that used gold standard measurements for AEE and PA but a limited sample size, genetic influence explained a large part of the variation in A EE and PA in daily life, whereas both AEEand PA were influenced by environment only within the confined area of the respiration chamber.

TL;DR: In this paper, a collaborative cross-sectional meta-analysis of observational studies was conducted to investigate the associations between BMI and leukocyte telomere length across the life span.

TL;DR: Genetic factors explain the greater part of the variation in traits related to obesity, glucose intolerance/insulin resistance and dyslipidaemia.

TL;DR: A higher BMI is associated with shorter telomeres, especially in younger individuals, and meta-analyses of longitudinal studies evaluating change in body weight alongside change in TL are warranted.
Journal ArticleDOI

TL;DR: This first Ad‐36 study in the Netherlands and in Belgium indicates that adenoviral DNA does not play a role as a direct cause of BMI increase and obesity in humans in Western Europe.
