Thyroid Dysfunction Prevalence and Risk Factors in the Southeastern Part of Bangladesh: A Cross-Sectional Study

Globally thyroid disorders (TDs) are common health issues including in the Southeast Asian region. The purpose of this study was to ascertain the prevalence of thyroid disorders in the Bangladeshi population, with a particular focus on the frequency, etiology, and comorbidity of various thyroid diseases.

A cross-sectional research design was conducted in the southeastern part of Bangladesh. Information regarding prior diagnosis and current management of TDs was obtained through a questionnaire.

Of the 300 respondents, 209 were female, and 91 were male. Females were found to be more predominant across all categories of TDs (χ ² = 17.738, p < 0.05). Furthermore, the older age group (31-45 years) demonstrated a higher frequency of thyroid problems (OR: 1.320). Specifically, hyperthyroidism was identified as the most common thyroid disorder, followed by hypothyroidism, and euthyroidism. Hyperthyroidism was found to be less common in males (18.69%) compared to females (43.06%), while hypothyroidism was more prevalent in males (46.15%) compared to females (27.75%). Multiple logistic regression analysis demonstrates that participants with a family history of TDs have a significantly higher chance (OR: 2.991, CI: 1.480-6.044, p < 0.05) of having hyperthyroidism than those without such a history. Interestingly, the studied population also exhibited higher rates of comorbidities including gastritis, diabetes, and cardiovascular diseases.

According to the study's findings, it is advised to concentrate on educating Bangladeshis about thyroid problems, particularly female population. Moreover, healthcare professionals should check elderly patient's thyroid conditions and consider the possibility that thyroid dysfunction can coexist with other conditions.
