Abstract
The purpose of the study is to research the effect of polymorphism of genes such as CLOCK, ARNTL, PER2, NPAS2, DRD4, DAT, TNF-α, and NPSR1 on sleep disorders in an open population of 25–64-year-old men. We conducted screening studies of representative samples of men aged 25–64 years. The general examination was carried out according to the standard methods included in the WHO MONICA-Psychosocial Program (MOPSY). Carriers of the C/T genotype of the CLOCK gene more often than others reported having “satisfactory” or “poor” sleep. Carriers of the C/T genotype of the ARNTL gene were more likely to experience anxiety dreams, and they woke up exhausted. Carriers of the A/A genotype of the PER2 gene were more likely to wake up two or more times per night, a total of four to seven times per week. In the population, C/T and T/T genotypes of the NPAS2 gene were significantly more common in individuals with 7-hour sleep. Genotype 4/6 of the DRD4 gene and genotype 9/9 of the DAT gene were significantly associated with sleep disturbances. Carriers of the heterozygous A/G genotype of the TNF-α-308 gene, compared with carriers of all other genotypes, more often rated sleep as “satisfactory” (30%) than “good.”
