oa Central African Journal of Medicine - Epidemiology of haemorrhoids in the adult Nigerian and English: A comparative study

Volume 33, Issue 3
  • ISSN : 0008-9176



In a hospital-based prospective study of the epidemiology of haemorrhoids in Nigeria and England, a prevalence of 0,8 and 7,5 per cent, respectively, was obtained. Seventy-six per cent of symptomatic haemorrhoids presented in the third and fourth decades in Nigerians and 75 per cent in the fourth to sixth in the English. The mean age at presentation was significantly higher among the English than among Nigerians (45,9 ± 14,0 vs 33,3 ± 8,9 years; p < 0,01), while the male: female ratio was similar (2,3 : 1 vs 2,2: 1, respectively) in both populations. Educated Nigerians and Nigerians in the middle social class and the English in the high social class appear to be at risk of developing symptomatic haemorrhoids. Although bowel frequency and stool characteristics indicated more English patients to be constipated (31 % vs 27%), more Nigerians than English took purgatives (58% vs 33%). Symptomatic haemorrhoids associated with obstructive uropathy, liver cirrhosis and pregnancy is not a common finding in this series.
