Baseline anxiety was significantly associated with an increased risk of incident diabetes (OR 1.47; 95% CI 1.23-1.75), whereas diabetes showed no association with incident anxiety.
Meta-Analysis (n=1,848,909)
Is there a longitudinal association between baseline anxiety and incident diabetes, or baseline diabetes and incident anxiety, in individuals aged 16 or older?
Baseline anxiety is associated with an increased risk of incident diabetes, adding to the evidence that poor mental health increases metabolic risk.
Odds Ratio: 1.47 (95% CI 1.23–1.75)
AIM: Previous research has indicated an association between diabetes and anxiety. However, no synthesis has determined the direction of this association. The aim of this study was to determine the longitudinal relationship between anxiety and diabetes. METHODS: We searched seven databases for studies examining the longitudinal relationship between anxiety and diabetes. Two independent reviewers screened studies from a population aged 16 or older that examined either anxiety as a risk factor for incident diabetes or diabetes as a risk factor for incident anxiety. Studies that met eligibility criteria were put forward for data extraction and meta-analysis. RESULTS: In total 14 studies (n = 1 760 800) that examined anxiety as a risk factor for incident diabetes and two (n = 88 109) that examined diabetes as a risk factor for incident anxiety were eligible for inclusion in the review. Only studies examining anxiety as a risk factor for incident diabetes were put forward for the meta-analysis. The least adjusted (unadjusted or adjusted for age only) estimate indicated a significant association between baseline anxiety with incident diabetes (odds ratio 1.47, 1.23-1.75). Furthermore, most-adjusted analyses indicated a significant association between baseline anxiety and incident diabetes. Included studies that examined diabetes to incident anxiety found no association. CONCLUSIONS: There was an association between baseline anxiety and incident diabetes. The results also indicate the need for more research to examine the direction of association from diabetes to incident anxiety. This work adds to the growing body of evidence that poor mental health increases the risk of developing diabetes.
Smith et al. (Wed,) conducted a meta-analysis in Diabetes and Anxiety (n=1,848,909). Baseline anxiety vs. No baseline anxiety was evaluated on Incident diabetes (OR 1.47, 95% CI 1.23-1.75). Baseline anxiety was significantly associated with an increased risk of incident diabetes (OR 1.47; 95% CI 1.23-1.75), whereas diabetes showed no association with incident anxiety.
