Prevalence and risk factors for abdominal wall hernia in the general Russian population

To find out the prevalence and risk factors for abdominal wall hernias in the general Russian population.

783 residents of Kryukovo rural community (Central Russia) of 10 > years were enrolled. Medical history was taken and clinical examination was performed documenting hernia presence. Ultrasound examination was performed in inconclusive situations. We considered residents with hernias at the time of examination, as well as those who had previously undergone hernia repair, to be hernia positive.

There were 298 (38%) men and 485 (62%) women (mean age 49.3). Abdominal wall hernias have been found in 20.9% of population. 31.2% of men and 14.6% of women were affected (p < 0.0001). Umbilical hernias was found in 10.2%, groin hernias in 8.3%, incisional in 2.4% of residents. 72% of individuals with hernia reported local pain. 70% had never asked for medical advice before, 30% had undergone hernia repair before. Male gender, age, family history were confirmed as risk factors for any hernia with OR 3.9, 1.03 and 2.7, respectively (p < 0.01). For groin hernias male gender, age, family history and rough labour were confirmed with ORs 9.2, 1.03, 2.9 (p < 0.01) and 2.1 (p < 0.05). Risk factors for umbilical hernias were male gender with OR 2.2 (p < 0.01), age, family history and BMI with ORs 1.02, 1.8 and 1.08 (p < 0.05).

This study is the first to demonstrate prevalence of abdominal wall hernias and its risk factors in Russia. The results confirm that hernias are common in a general population pointing the need for improvement of surgical activity.
