Overview
Epidemiology and Demographics
The epidemiology and demographics of toxic multinodular goiter is as below:[1][2][3][4][5]
Incidence
- The incidence of toxic multinodular goiter is estimated to be 4.8 cases per 100,000 population per year.
- The incidence of toxic multinodular goiter may be related to the degree of iodine sufficiency.
- Correction of mild iodine deficiency has beneficial effects on the incidence of hyperthyroidism.
- In 1988-89, the correction of mild iodine deficiency led to a steady decline in the total incidence to reach 44% of the control level.
- The decline in total incidence was attributed to a decrease in the incidence of toxic nodular goiter.
Prevalence
- The prevalence of hyperthyroidism is estimated to be 2000 cases per 100,000 population.
- The prevalence of toxic multinodular goiter is 100 cases per 100,000 population and accounts for 5% of all patients with hyperthyroidism.
- The prevalence of toxic adenomas in United States was estimated to be 1.6% of 2846 thyrotoxic patients in a research done in Cleveland. In other words, the prevalence of toxic adenomas in United States is 1580 cases per 100,000 population.
- The prevalence of toxic thyroid nodules was significantly higher in an iodine-deficient population when compared with an iodine-sufficient population.
- In iodine deficient areas, such as some areas of Italy (Pescopagano, in southern Italy), nodular goiter is present in 25-33% of the population.
=Age
- Toxic multinodular goiter commonly affects individuals older than 60 years of age.
- Hyperthyroidism associated with an autonomous nodule occurred in 57% of patients aged more than 60 years, whereas 13% of those younger than 60 years were hyperthyroid.
- Toxic multinodular goiter frequency increases with age.
Race
In a recent study, the incidence of malignancy in TMG was found to be 7% and most of them were papillary microcarcinomas.[6]
Gender
- [Gender 1] are more commonly affected by [disease name] than [gender 2]. The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.
- was noted to be higher specifically in females aged 50 years or older.
- Toxic nodules were seen in women six times more than in men.
- All benign thyroid disorders showed predominance in women. Male/female ratio was 1/10 (10%) in the TMG group and 6/12 (50%) in the NMG group in our study. We also found a significant difference in the incidence of malignancy in male patients between the two groups and the incidence of malignancy was found to be higher in the non-toxic male patients.
Region
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
- Chiefly because of the iodination of table salt in the United States, the iodine intake of 200 to 600 μg/day in the United States is significantly higher than the nearly borderline deficient intake of 25 to 100 μg/day in many areas of Europe.
- A higher incidence is seen in European countries in comparison with the United States. A general survey of six countries in Europe in 1986 revealed that 9% of thyrotoxic patients had autonomous nodules. In Malmo, Sweden, the mean annual incidence of thyrotoxicosis rose in 1988 to 1990 compared with the incidence in 1970 to 1974.
