Summary
Cholecystitis, rare in Africa, is increasing in Nigerian urban areas due to Western diet adoption. This study highlights a shift in disease prevalence, particularly affecting females.
Area of Science:
- Gastroenterology and Epidemiology
- Public Health and Nutrition
Background:
- Colo-rectal carcinoma, diverticular disease, and cholecystitis are historically rare in African populations.
- Significant socio-economic changes in Nigeria over two decades include the adoption of Western dietary items, especially in urban areas.
Purpose of the Study:
- To document the changing prevalence of cholecystitis in Nigerian urban populations.
- To identify potential contributing factors to the observed increase in cholecystitis cases.
Main Methods:
- Retrospective collection of 69 cholecystitis cases over a five-year period.
- Analysis of patient demographics, including age and gender distribution.
Main Results:
- A notable increase in cholecystitis cases was observed compared to previous Nigerian reports.
- The female to male ratio for cholecystitis was 5.3:1.
- The age range was 10-66 years, with a median age of 36.9 years for females and 49 years for males.
Conclusions:
- The rising incidence of cholecystitis in Nigeria may be linked to increased hospital admissions.
- Dietary changes incorporating Western food items and the use of oral contraceptive pills are probable contributing factors to increased cholecystitis occurrence.
