AIMS: To evaluate: (i) the prevalence of habitual snoring (HS) in a large sample of children aged from birth to 36 months in 14 countries across Asia Pacific; and (ii) the different correlates associated with HS in Caucasians, Chinese and non-Chinese, non-Caucasian Asians. METHODS: This was a multi-centre, cross-sectional survey conducted across Asia Pacific. Parents/caregivers of 23,481 infants and toddlers completed an expanded version of the Brief Infant Sleep Questionnaire. We defined HS as snoring more than three nights per week. RESULTS: Chinese and non-Caucasian non-Chinese (NCNC) children had a lower prevalence of HS across the age range from birth to 3 years than their Caucasian counterparts (6.2% and 5.1% vs. 11%, P < 0.01). Boys had a higher prevalence of HS compared to girls (χ(2) = 98.5, P < 0.0001). History of prematurity (OR = 1.37-1.56, CI (1.1-2.17), P < 0.01) and gender (OR = 1.53-1.54, CI (1.26-1.85), P < 0.0001) were found to be significant predictors for HS. Current breastfeeding (OR = 0.69, CI (0.54-0.88), P < 0.005) and greater parental age (OR = 0.86, CI (0.78-0.96), P < 0.01) were protective against HS among NCNC children. HS was less prevalent in younger Chinese subjects (OR = 0.88, CI (0.84-0.93), P < 0.0001). In Caucasians, parents' education (OR = 0.78, CI (0.67-0.91), P < 0.005) and their not sleeping in the same room as their child (OR = 0.62, CI (0.45-0.86), P < 0.005) were negatively associated with parental report of HS. CONCLUSIONS: Prevalence of HS shows racial differences among countries across Asia Pacific. Future studies should assess craniofacial structure and body fat distribution as contributory factors for this differential prevalence.
