Despite the claims that umbilical hernia (UH) is common among Nigerian children, the socio-economic class-related prevalence or incidence rate of UH in the Nigerian children is not known. We therefore undertook this study to determine the prevalence of UHs among Nigerian children of high socio-economic class.
This 7- years prospective study assessment of the prevalence of primary umbilical hernias among a private school admission seeking Nigerian children. Clinical evaluations of the umbilicus were conducted on 7,968 Nigerian children, attending interview into Nigerian Airforce Military schools from across the country.
Umbilical hernia was present in 102 (1.3% ) out of 7968 children, giving a prevalence of 12.8 per 1,000. Fifty-three (52.% ) were boys and 49 (48% ) were girls; their ages ranged from 6 to 9 years (mean 6.5 years). Umbilical hernia was 1.4 times as common in the girls as in the boys, with a prevalence of 15.3 per 1,000 and 11.1 per 1,000, respectively. The overall prevalence in this study is comparatively lower than those previously reported.
Our study suggests that there is a low prevalence rate of UH among the children of high socio-economic class in Nigeria.
尽管有人声称脐疝（UH）在尼日利亚儿童中很常见，但尼日利亚儿童中与社会经济阶层相关的脐疝患病率或发病率尚不清楚。因此，我们开展了这项研究，以确定高社会经济阶层的尼日利亚儿童中脐疝的患病率。
这项为期7年的前瞻性研究评估了尼日利亚私立学校入学儿童中原发性脐疝的患病率。对来自全国各地、参加尼日利亚空军军校面试的7968名尼日利亚儿童进行了脐部的临床评估。
7968名儿童中有102名（1.3%）患有脐疝，患病率为每1000人中有12.8人。53名（52%）为男孩，49名（48%）为女孩；他们的年龄在6至9岁之间（平均6.5岁）。女孩患脐疝的几率是男孩的1.4倍，患病率分别为每1000人中有15.3人和11.1人。本研究中的总体患病率相对低于先前报道的患病率。
我们的研究表明，尼日利亚高社会经济阶层儿童的脐疝患病率较低。
