Various studies found that thyroid dysfunction is common in type 2 diabetes and it is associated with poor blood glucose control and chronic diabetic complications responsible for morbidity and mortality. However, only limited studies have assessed determinants of thyroid dysfunctions among type 2 diabetes in Ethiopia. Methods Unmatched case-control study conducted in two private hospitals found in Dire Dawa town, between May - November 2021. A total of 92 type 2 diabetic patients with thyroid dysfunction as Cases and 183 type 2 diabetes patients with normal thyroid function as controls selected by purposive and systematic random sampling, respectively. Data collected by interview and using checklist, entered into SPSS version 22, and analyzed. Bivariate and multivariate logistic regression analysis employed to identify determinants of thyroid dysfunction with AOR and 95%CI. Independent t-test computed to observe significant mean difference of continuous variables. Variables with P-value < 0.05 declared as significant. Result Female gender predominate 65.9% of participants (p= 0.02). The mean glycated hemoglobin level among cases was 10.32 ({+/-} 2.4 SD) and 9.249 ({+/-} 2.3 SD) among controls, with significant difference (p=0.001). Similarly, the mean LDL cholesterol among cases 116.92 {+/-}45.9 SD and control 102.34 {+/-}43.97SD showed significant difference (p=0.016). Diabetic retinopathy and neuropathy, and ACEI/ARB also significantly associated with thyroid dysfunction (p< 0.05). Conclusion Female gender, lower educational level, and duration of diabetes associated with thyroid dysfunction. Most patients in both groups had unacceptably elevated HgA1c which need to be addressed. Thus, screening for thyroid dysfunction, especially the female gender, needs to be done. is the author/funder, who has granted medRxiv a license to display the preprint in (which was not certified by peer review) preprint The copyright holder for this this version posted February 5, 2022. ; https://doi.org/10.1101/2022.02.03.22270379 doi: medRxiv preprint NOTE: This preprint reports new research that has not been certified by peer review and should not be used to guide clinical practice.

This study assesses, the association of glycemic control with thyroid dysfunction, predictors 303 of thyroid dysfunction, and association of thyroid dysfunction with chronic diabetic 304 complications. In this study degree of blood glucose control in diabetes patients with thyroid dysfunction is 307 poorer than controls as the mean glycated hemoglobin level was 10.32 ± 2.4% and it was 308 9.249 ± 2.3% in controls. The difference is statistically significant (p= 0.001) which 309 underlines the association of chronic hyperglycemia and thyroid dysfunction. A similar case- is the author/funder, who has granted medRxiv a license to display the preprint in (which was not certified by peer review) preprint As insulin resistance is thought to be central in the pathophysiology of the development of 316 thyroid dysfunction, the duration of diabetes has been considered to be an important risk for 317 thyroid dysfunction (more than 5 years) mainly in hypothyroidism. Our finding revealed that 318 T2DM patients with 5 to 10 years duration of diabetes had higher odds of developing thyroid 319 dysfunction than less duration. However, there is no association in this study [27, 14, 26] 320 In this study, females formed 65% of participants, and being female has 2.5 times the odds of is the author/funder, who has granted medRxiv a license to display the preprint in (which was not certified by peer review) preprint Since TD is associated with poor blood glucose control, it is expected to worsen and It is known that hypothyroidism and T2DM are independently linked to the development of 361 coronary artery disease.
