BASE STATIONS OF MOBILE COMMUNICATIONS AND PUBLIC HEALTH OF KRASNODAR REGION
We studied the relationship between the specific number base stations (SNBS) of cellular communication (units per 100 thousand population) and the level of primary morbidity of the adult population (18 years and older, only about 4 million people) and the frequency of disease III (D50-D89), IV (E00-E90) and V (F00-F99) classes in 44 districts of the Krasnodar Territory in 2001–2012. We used regression analysis, Pearson´s correlation coefficient was calculated, relative (RR) and attribute (EF%) risk, comparing the percentage of districts with forward and backward linkages between the SNBS and morbidity. Of all the municipalities of the region areas with direct correlation between the level of the primary disease and the SNBS significantly prevailed over the areas of feedback, however, the most significant risk areas were in the group with the highest value of the SNBS (t=3,7; RR=3,67; EF=72,7%; r=0,64; P<0.05). The relationship between the SNBS and the frequency of the class III disease was statistically significant (generally among all 44 areas t=3,67; RR=2,14; EF=53,4%; r=0,824; P<0,001) for except for groups of areas with low SNBS. Also shown a significant relationship between the frequency of disease Class IV and BS network development especially in areas with an average level of the SNBS (t=9,5; RR=13,99; EF=92,85±6,65%; r=0,867; P=0,0002). There was an inverse relationship between the SNBS and the spread of disease Class V (overall among 44 areas: t=11,3; RR=7,8; EF=87,1%; r=-0,9; P=0,0001).
