Stress and Adiposity: A Meta-Analysis of Longitudinal Studies
TLDR
In this article, the authors brought together results from published, longitudinal, prospective studies examining associations between psychosocial stress and objectively measured adiposity in a meta-analysis and concluded that stress was associated with increasing adiposity.Abstract:
Psychosocial stress has been strongly implicated in the biology of adiposity but epidemiological studies have produced inconsistent results. The aim of this analysis was to bring together results from published, longitudinal, prospective studies examining associations between psychosocial stress and objectively measured adiposity in a meta-analysis. Searches were conducted on Medline, PsycINFO, Web of Science, and PubMed (to January 2009) and reference lists from relevant articles were examined. Prospective studies relating psychosocial stress (general life stress (including caregiver stress), work stress) to BMI, body fat, body weight, waist circumference, or waist-to-hip ratio were included. Analyses from 14 cohorts were collated and evaluated. There was no significant heterogeneity, no evidence of publication bias, and no association between study quality and outcomes. The majority of analyses found no significant relationship between stress and adiposity (69%), but among those with significant effects, more found positive than negative associations (25 vs. 6%). Combining results in a meta-analysis showed that stress was associated with increasing adiposity (r = 0.014; confidence interval (CI) = 0.002-0.025, P < 0.05). Effects were stronger for men than women, in analyses with longer rather than shorter follow-ups, and in better quality studies. We conclude that psychosocial stress is a risk factor for weight gain but effects are very small. Variability across studies indicates there are moderating variables to be elucidated.read more

TL;DR: Among patients with CHD, acute psychological stress has been shown to induce transient myocardial ischemia and long-term stress can increase the risk of recurrent CHD events and mortality, and the importance of stress management is highlighted in European guidelines for cardiovascular disease prevention.

TL;DR: A meta-analysis of 41 studies revealed that childhood maltreatment was associated with elevated risk of developing obesity over the life-course, and the association was stronger in samples including more women and whites, but was not influenced by study quality.

TL;DR: In real-life settings, mechanistic studies have corroborated earlier laboratory-based observations on stress-related pathophysiological changes that underlie triggering, such as lowered arrhythmic threshold and increased sympathetic activation with related increases in blood pressure, as well as pro-inflammatory and procoagulant responses.

TL;DR: Greater reported stress, both exposure and perception, was associated with indices of greater drive to eat-including feelings of disinhibited eating, binge eating, hunger, and more ineffective attempts to control eating.

Bias in meta-analysis detected by a simple, graphical test
TL;DR: Funnel plots, plots of the trials' effect estimates against sample size, are skewed and asymmetrical in the presence of publication bias and other biases Funnel plot asymmetry, measured by regression analysis, predicts discordance of results when meta-analyses are compared with single large trials.
