Abstract

Purpose

The aim of this study was to study the interactions among age, gender, and snoring across all age groups

Methods

All cross-sectional study reporting gender-specific prevalence of snoring in general population published from 1966 through July 2008 were included and were meta-analyzed. The sources of heterogeneity among primary studies were studied by meta-regression.

Results

From a total of 1,593 citations reviewed, 63 were included in the analysis of snoring. These 63 studies were comprised 104,337 and 110,474, respectively. A combined odds ratio of 1.89 with a 95% confidence interval of 1.75–2.03 for male versus female was found. The heterogeneity was significant with an estimated between-study variance, τ 2 being 0.065 and 95% confidence interval of 0.0397–0.0941. Multiple meta-regression showed that age were the significant effect modifier of the relationship between snoring and gender.

Conclusion

This study found a consistent male predominance in snoring among the general population, and the heterogeneity in the risk of snoring between two genders can be partly explained by age.
