Objective:
To investigate whether patients with diabesity (the combination of both conditions) have a higher mortality risk than isolated obesity or type 2 diabetes (T2D), particularly when waist-circumference (WC) is used as a criterion for obesity.
Materials And Methods:
This longitudinal study included 4 514 Chilean participants from the Chilean National Health Survey 2009 and 2010. Participants were categorized into four groups based on WC and diagnosis of diabetes: a) normal, b) abdominal obesity-only, c) T2D-only, and d) diabesity. Cox proportional hazard models were performed to investigate the associations between diabesity and all-cause mortality. Analyses were also replicated using body mass index (BMI) categories.
Results:
After a median follow-up of 10.9 years, 445 (9.9%) participants died. In the fully-adjusted model, compared with participants with normal-conditions, those with diabesity had 1.37 (95%CI: 1.01,1.85) times higher all-cause mortality risk.
Conclusions:
Individuals with diabesity had a higher mortality risk compared to their counterparts. The WC instead of BMI can be a more sensitive predictor of mortality risk in the Chilean population.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
