摘要Background/Aim:
Household tobacco exposure in young children causes significant disease and economic burden. This study aimed to examine the prevalence and to explore the associations between household tobacco exposure and family socioeconomic status, recent respiratory symptoms and medical service utilisations in Hong Kong young children.
Methods:
Analysis was performed on data obtained from a community-based cross-sectional pneumococcal carriage surveillance study of healthy children aged under 2 years across 4 main regions of Hong Kong. Information on demographics, household tobacco exposure, family socioeconomic status, children’s recent respiratory symptoms and medical service utilisation was obtained by parent-reported questionnaires.
Results:
1541 subjects (mean age: 11.2 months, male: 50.7%) recruited from June 2013 to June 2014 were included in the analysis. The prevalence of household tobacco exposure was 31.5%, prevalence of prenatal and postnatal maternal smoking was 1.6% and 3.5% respectively. After adjustment for potential confounding factors, low household income (AOR=1.38, 95% CI: 1.08-1.76), overcrowding of household living area (AOR=3.13, 95% CI: 2.00-4.89), residing in Kowloon (AOR=1.55, 95% CI: 1.11-2.15) and New Territories West (AOR=1.65, 95% CI: 1.18-2.32) were independently and significantly associated with household tobacco exposure. Practice of breastfeeding was significantly associated with lower odds of having household tobacco exposure (AOR=0.65, 95% CI: 0.50-0.84). Household tobacco exposure (AOR=1.33, 95% CI: 1.03-1.70) and postnatal maternal smoking exposure (AOR=2.30, 95% CI: 1.09-4.85) were significantly associated with doctor consultation in recent 3 months; postnatal maternal smoking exposure (AOR=2.70, 95% CI: 1.16-6.27) was significantly associated with hospitalisation in recent 3 months. However, household tobacco exposure was not significantly associated with recent respiratory symptoms in our cohort.
Conclusion:
As home is the most significant source of environmental tobacco exposure for young children, efforts for reducing such exposure are essential especially in socially deprived population.
