Türkiye'de Yapılan Tez Çalışmalarında Sigara İçiminin Uyku Kalitesi Üzerine Etkisinin Değerlendirilmesi: Meta-analiz.

Objective: This meta-analysis aimed to identify the sleep quality between smokers and non-smokers within Turkish research published in the last 10 years. Turkish studies on the sleep quality and smoking published from 2010 to 2020 in the national thesis centre were systematically screened. The effect size was calculated according to the odds ratio and analysed with CMA V3 program. Cochrane Q statistics and I2 value for heterogeneity analysis and funnel plot, Egger's Linear Regression test, Begg and Mazumdar rank correlations statistics, trim-and-fill method for publication bias were performed. Of 132 papers in ten years, 26 coding on smoking and good sleep quality were evaluated using a forest plot graph. By using the fixed effects model, a small effect in favour of good sleep quality (d=1.697, 95% confidence interval 1.501-1.920, p=0.000) was found in non-smokers. Heterogeneity test and I2 value found a significant and moderate heterogeneity between studies (Q=59,672, p=0.000, I2=58,104). In the subgroup analysis, the mixedgender group (p=0.001 I2=55,807) and medicine field studies (p=0.001 I2=60,874) had a moderator role. No study had significantly found that non-smokers had poorer sleep than smokers (p>0.05). The results suggest that one of every four people is a smoker, and one of every two people had a poor sleep quality. Moreover, 69.7% of the non-smokers (approximately 1.7 times) had a better sleep quality than smokers. Promoting smoking cessation for good sleep has been proposed based on national research data.
