Prevalence of CHD possibly presence in a sample epidemiological study, taking into account the socio-economic characteristics of the participants

Aim of the study was to analyze the socio-economic determinants and prevalence of possibly presence CHD in residents of a large industrial region.

Material and methods. The study sample included residents of rural settlements of the Kemerovo region and districts of the city of Kemerovo. The study involved 1600 respondents aged 35-70 years. The determinants of socio-economic status (SES) were assessed: the level of education and income, professional affiliation, marital status / family composition, place of living.

Results. The majority residents of rural settlements (50.9 %) had a secondary vocational education, compared with urban residents (46 %). A high level of income (over 20 000 rubles) was observed 1.53 times more often among the urban population than rural population. It was revealed that one third (29.3 %) of the rural population is employed in agriculture, and about 40.4 % do work that does not require vocational qualification. Among residents of rural settlements, there are statistically significant more those marriage/living with a partner, than among urban residents (75.6 % versus 62.9 %, respectively). The SES analysis of the study participants with possibly presence CHD indicates a predominant share (50.9 %) of vocational secondary education and medium income level (48.9 %). It was revealed that among the lonely rural residents possibly presence CHD occurred 10.0 % more often (urban 26.7 %, rural 36.7 %, p = 0.035) than among those living in the city.

Conclusion. In the Kemerovo Oblast CHD possibly presence is more common in women, depending on socio-economic determinants it is more often observed in persons with a secondary vocational education and medium income level, equally among both skilled and low/ unskilled workers living with partner in urban settings.
