Inguinal hernia is a common surgical problem, with a lifetime risk of 27% in men and 3% in women. Its cumulative incidence is 17.2% and 12.3% in body mass index of <25 kg/m2 and 25-30 kg/m2 respectively. Obesity had been regarded as the risk factor for the development of an inguinal hernia. However, recent epidemiologic studies have suggested the decreased prevalence of inguinal hernia in increased weight and body mass index individuals. The aim of this study is to find out the prevalence of obesity in inguinal hernia repair patients in a tertiary care center.
A descriptive cross-sectional observational study was performed in Bir Hospital from May 2018 to December 2019 after taking ethical approval from the institutional review board of NAMS. Convenient sampling was done with a sample size of 219. Statistical analysis was done using SPSS version 23 and Microsoft Excel software by descriptive statistics.
The mean body mass index was 22.10±3.07 kg/m2. Body mass index category 18.5-22.9 kg/m2 had 133 (61%) male and seven (3.2%) female patients, category ≥30 kg/m2 had four (1.8%) male. Most of inguinal hernia repair patients were farmers 158 (72.5%). Common risk factors noted were smoking 142 (65.1%), heavy work 112 (51.4%), chronic cough 65 (29.8%). Most of the complications occurred in the normal body mass index category and the prevalence of complications decreased as the body mass index increased. The recurrence was found in 3 (1.4%) inguinal hernia repairs.
The majority of inguinal hernia repair patients were non-obese, and complications were less in obese patients.
腹股沟疝是一种常见的外科问题，男性终生风险为 27%，女性为 3%。其累积发病率分别为<25kg/m2 时的 17.2%和 25-30kg/m2 时的 12.3%。肥胖一直被认为是腹股沟疝发展的危险因素。然而，最近的流行病学研究表明，超重和肥胖人群中腹股沟疝的患病率有所下降。本研究旨在探讨三级保健中心腹股沟疝修补患者肥胖的患病率。
本研究为描述性横断面观察性研究，于 2018 年 5 月至 2019 年 12 月在 Bir 医院进行，研究方案获得了 NAMS 机构审查委员会的伦理批准。采用便利抽样法，样本量为 219 例。采用 SPSS 版本 23 和 Microsoft Excel 软件进行统计分析，采用描述性统计方法。
平均体重指数为 22.10±3.07kg/m2。体重指数 18.5-22.9kg/m2 组有 133 例（61%）男性和 7 例（3.2%）女性患者，体重指数≥30kg/m2 组有 4 例（1.8%）男性。大多数腹股沟疝修补患者为农民，共 158 例（72.5%）。常见的危险因素包括吸烟 142 例（65.1%）、重体力劳动 112 例（51.4%）、慢性咳嗽 65 例（29.8%）。大多数并发症发生在正常体重指数组，体重指数增加时并发症的发生率降低。发现 3 例（1.4%）腹股沟疝修补术后复发。
大多数腹股沟疝修补患者为非肥胖患者，肥胖患者的并发症较少。
