Smoking and sleep disorders (population-based study under the WHO “MONICA-psychosocial” program)

Abstract

Objective : to study the connection between smoking and sleep disorders in the open population of 45–64 year old in Novosibirsk. Patients and methods . IV screening of the population was carried out in 2003–2005, 1650 persons were examined (576 men, mean age – 54.23±0.2 years, response – 61%; 1074 women, mean age – 54.27±0.2 years, response – 72%). Attitudes towards smoking were studied using the scale “Knowledge and attitude to one's health” of the WHO “MONICA-psychosocial” program. To study sleep disorders and sleep duration, a standard Jenkins questionnaire was used. Results and discussion . In an open population of 45–64 years of age, 65.8% of men experienced sleep problems (satisfactory sleep – 53.6%, poor sleep – 12.2%) and 78.6% of women (satisfactory sleep – 58.9%, poor sleep – 19.7%; χ 2 =38.553; df=2; p<0.001). 78.9% of men and 34.7% of women smoked (χ 2 =313.175; df=5; p<0.001). Men who smoke more often rated sleep as “bad” (82.9%) than “good” (76.2%; χ 2 =32.267; df=10; p<0.001). Women who tried to quit smoking were more likely to have “bad” sleep (4.7%) than “good” sleep (2.6%; χ 2 =69.747; df=10; p<0.001). Among male smokers, the duration of sleep was 5–6 hours (76.9%) more often than 9–10 hours (67.6%; χ 2 =3.696; df=2; p>0.05). Women who smoke were more likely to report 5–6 hours of sleep (30%) than 9–10 hours (18.2%). Conclusion . It has been established that smoking men and women aged 45–64 are more likely to experience both sleep disorders and lack of sleep.
