Overview
Epidemiology and Demographics
Incidence
- The incidence of inguinal hernia is approximately 110 per 100,000 individuals in years aged 16-24 years to 2000 per 100,000 person years aged 75 years or above in men.[1]
Prevalence
- The prevalence of inguinal hernia is approximately 1700 per 100,000 individuals for all ages and 4000 per 100,000 for those aged over 45 yearsworldwide.[2]
Case-fatality rate/Mortality rate
- The 30 day mortality rate of 2000 per 100,000 in patients under 60 years old and 48000 per 100,000 individuals in those over 60 years old after elective surgery.[3]
Age
- Patients of all age groups may develop inguinal hernia.[4]
- The incidence of inguinal hernia increases with age; the median age at diagnosis is 40-59 years.[5]
- Direct inguinal hernia commonly affects middle-aged and elderly individuals because the abdominal walls weakens with age.
- Indirect inguinal hernias can occur at any age including the young individuals.
Race
- There is no racial predilection to [disease name].
- [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].
Gender
- [Disease name] affects men and women equally.
- [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.
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].
