Epidemiology and Demographics

Incidence

• The incidence of hyperparathyroidism is approximately 0.4 to 21.6 per 100,000 person years.

Prevalence

• The prevalence of prolactinoma is approximately .01 to .07 per 100,000 individuals.

Age

• Patients of all age groups may develop [disease name].
• The incidence of primary hyperparathyroidism increases with age.
• In individuals age < 50 years, the incidence of primary hyperparathyroidism ranges from a low of 12 per 100,000 person years to a high of 24 per 100,000 per person years.
• [Chronic disease name] is usually first diagnosed among [age group].
• [Acute disease name] commonly affects [age group].

Race

• Primary hyperparathyroidism usually affects individuals of African-American race.
• The incidence of Primary hyperparathyroidism according to race is as follows:

Incidence of Primary hyperparathyroidism according to race
Race	Gender (incidence per 100,000 person years)
	Women	Men
African-American	92	46
White	81	29
Asian	52	28
Hispanic	49	17
Other race	25	6

Gender

• Women are more commonly affected by hyperparathyroidism than men. The women to men ratio is approximately 3 to 1.
• In women, the incidence of primary hyperparathyroidism ranges from a low of 34 per 100,000 person years to a high of 120 per 100,000 person years with an average incidence of 66 per 100,000 person years.
• In men, the incidence of primary hyperparathyroidism ranges from a low of 13 per 100,000 person years to a high of 36 per 100,000 person years with an average incidence of 24 per 100,000 person years.
• Sex difference becomes more pronounced with advancing age.

Incidence of primary hyperparathyroidism in different age group
Age group	Gender (incidence per 100,000 person years)
	Women	Men
Age < 50 years	12-24	12-24
Age 50 - 59 years	80	36
Age 70-79 years	196	95

Region

• The majority of [disease name] cases are reported in [geographical region].

• [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
