Epidemiological study of the previousness of the symptoms of gastroesophageal refl ux disease in residents of the baykal territory with account of ethnic peculiarities of the population

Aim. Study of the prevalence of gastroesophageal refl ux disease among residents of the Trans- Baikal Territory, taking into account its ethnic composition.

Materials and methods. By the method of random household walk, the study included persons over 18 years of age. The GerdQ questionnaire was applied. Additionally, passport data, information on smoking, alcohol use, coff ee, anthropometric data, social status, membership in a particular ethnic group (Buryats, Europoids) are collected. Four groups were analyzed: the 1st Caucasians, who scored 8 or more points on the GerdQ questionnaire and the 2nd — Caucasians, who scored less than 8 points, the 3rd group—the Buryats, who scored 8 or more points, and the 4th—Buryats, not scored 8 points. For statistical processing used the program Statistica 10.0, the diff erences were considered signifi cant when p< 0.05.

Results. 371 profi les were selected for analysis. 8 or more points on the GerdQ questionnaire scored 48 people (12.9%). 236 people—Caucasians (63.6%) and 135 Buryat people (36.4%), while the latter had more rare manifestations of GERD (38 Caucasians (16.1%) and 10 Buryats (7.4%) p = 0.009). The average age of persons of the 1st group was 53.4 ± 17.47 years and exceeded that of the 2nd group (46.2 ± 19.2 years), p = 0.035. Manifestations of GERD in Buryats were observed at a younger age and did not diff er between the 3rd and 4th groups. There was no correlation between GERD symptoms and bad habits (smoking, alcohol). The dependence of GERD symptoms with coff ee consumption and obesity has not been established.

Conclusion. The prevalence of symptoms of gastroesophageal reflux disease in the territory of the Trans- Baikal Territory is below the national indicators, which is probably related to the ethnic composition of the population. Age-related features of the identification of symptoms of GERD are characteristic only for Caucasians.
