To date, there are no prospective population-based cohort studies investigating the association across the full range of thyroid function, including the normal range, with the risk of diabetes. As a consequence, there is no consensus regarding whether patients with thyroid dysfunction should be screened for diabetes. Only few studies have investigated the association of thyroid function with incidence of diabetes prospectively and all were register-based studies, again reporting conflicting results. However, cross-sectional studies have several limitations, including lack of assessment of temporality. Further, one of the most recent and largest cross-sectional studies reports no association between thyroid dysfunction and type 2 diabetes. There are several cross-sectional reports on the association between thyroid dysfunction and diabetes, albeit with conflicting results, with some studies reporting an association between hyperthyroidism and type 2 diabetes, while others report instead an association between hypothyroidism and diabetes. Interestingly, lack of thyroid hormone is also associated with a decrease in peripheral insulin sensitivity and glucose intolerance and treatment of hypothyroidism has been shown to improve insulin sensitivity. hyperthyroidism) causes increased liver gluconeogenesis and peripheral insulin resistance and is associated with glucose intolerance. However, the deleterious effect of thyrotoxicosis on glucose metabolism has also been recognized for decades.

Hyperthyroid individuals have an increased insulin secretion and higher free triiodothyronine levels are specifically associated with improved insulin secretion in individuals with prediabetes. Thyroid hormone is a major regulator of metabolism and energy expenditure, is directly involved in the control of insulin secretion and glucose homeostasis, and has been shown to preserve beta-cell viability and proliferation.

A relation between thyroid dysfunction and type 2 diabetes mellitus has also been suggested, but the possible underlying mechanisms and drivers show complex interactions. The role of auto-immunity has been well-recognized in the link between auto-immune thyroid disease and type 1 diabetes mellitus. Future studies should investigate whether screening for and treatment of (subclinical) hypothyroidism is beneficial in subjects at risk of developing diabetes.ĭiabetes mellitus and thyroid disease are the two most common endocrine disorders, often co-existing in patients. Low and low-normal thyroid function are risk factors for incident diabetes, especially in individuals with prediabetes. Absolute risk of developing diabetes type 2 in participants with prediabetes decreased from 35 % to almost 15 % with higher FT4 levels within the normal range. The risk of progression from prediabetes to diabetes was higher with low-normal thyroid function (HR 1.32 95 % CI, 1.06–1.64 for TSH and HR 0.91 95 % CI, 0.86–0.97 for FT4). Higher FT4 levels were associated with a lower diabetes risk amongst all participants (HR 0.96 95 % CI, 0.93–0.99, per 1 pmol/L) and in participants within the reference range of thyroid function (HR 0.96 95 % CI, 0.92–0.99). Higher TSH levels were associated with a higher diabetes risk (hazard ratio 1.13 95 % confidence interval, 1.08–1.18, per logTSH), even within the reference range of thyroid function (HR 1.24 95 % CI, 1.06–1.45). Resultsĭuring a mean follow-up of 7.9 years, 798 diabetes cases occurred. Multivariable models were adjusted for age, sex, high-density lipoprotein cholesterol, and glucose at baseline, amongst others. Cox-models were used to investigate the association of TSH and FT4 with diabetes and progression from prediabetes to diabetes. We included 8452 participants (mean age 65 years) with thyroid function measurement, defined by thyroid-stimulating hormone (TSH) and free thyroxine (FT4), and longitudinal assessment of diabetes incidence.

We aimed to investigate the association of thyroid function with incident diabetes and progression from prediabetes to diabetes in a population-based prospective cohort study. The association of thyroid function with risk of type 2 diabetes remains elusive.
