Folate deficiency may increase the risk for elevated TSH in patients with type 2 diabetes mellitus.

BACKGROUND: Type 2 diabetes mellitus (T2DM) and thyroid dysfunction (TD) are two common chronic endocrine disorders that often coexist. Folate deficiency has been reported to be related with the onset and development of T2DM. However, the relationship between folate deficiency and TD remains unclear. This study aims to investigate the association of serum folate with TD in patients with T2DM. METHODS: The study used data on 268 inpatients with T2DM in the Beijing Chao-yang Hospital, Capital Medical University from October 2020 to February 2021. Thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), and serum folate were measured with chemiluminescence immunoassay (CLIA), and folate deficiency was defined as a serum folate concentration < 4.4 ng/mL. Ordinary least squares regression models were used to assess the association of serum folate with TSH concentration. Multivariable logistic regression models were performed to explore the correlation of folate deficiency and the risk for elevated TSH. RESULTS: 15.3% of T2DM patients had TD. Among those patients with TD, 80.5% had elevated TSH. Compared with the normal-TSH and low-TSH groups, the prevalence of folate deficiency was significantly higher in the elevated-TSH group (P < 0.001). Serum folate level was negatively associated with TSH (ß=-0.062, 95%CI: -0.112, -0.012). Folate deficiency was associated with the higher risk for elevated TSH in patients with T2DM (OR = 8.562, 95%CI: 3.108, 23.588). CONCLUSIONS: A low serum folate concentration was significantly associated with a higher risk for elevated TSH among T2DM patients.

Healthy Lifestyles and Chronic Pain with New-Onset Metabolic-Related Multimorbidity among Older Adults - China, 2011-2018.

What is already known about this topic?: Chronic pain has been identified as a risk factor for cardiovascular diseases. Evidence shows that adopting a healthy lifestyle can help reduce the cardiometabolic risks associated with chronic pain. What is added by this report?: Results from this cohort study suggest a positive association between chronic pain and the development of new-onset metabolic-related multimorbidity, specifically metabolic multimorbidity and cardiometabolic comorbidity, within middle-aged and older Chinese adults. Furthermore, adopting healthy lifestyles can potentially mitigate or even reverse these associations. What are the implications for public health practice?: The results of our study emphasize the importance of promoting healthy lifestyles among older Chinese adults as a preventative measure against the medical burdens and cardiometabolic risks associated with chronic pain.
