According to the results of the study, in non-marine towns located at a distance of at least 30 km from the coast of the Caspian Sea, the incidence of acne (Me 421.5, P25 408.1, P75 679.8 per 100,000 population) exceeded, then indicator for coastal towns (Me 171.7, P25 152.5 and P75 199.2 per 100,000 population) RD with a sharp increase in 2010-2012. According to the incidence of acne, the non-marine town Khasavyurt (Me 754.8, P25 719.1, P75 307.8 per 100,000 population) is the most disadvantaged, the incidence of which is 5.2 times higher than the average for all towns (Me 242.5; P25 230.8, P75 314.4 per 100,000 population).
