Abstract

Introduction: Majority of children are involuntarily exposed to tobacco smoke mainly by adults, in the places where children live, work and play. There has been recent evidence of a relationship between poor cognitive performances and Secondhand smoke (SHS) exposure. Cotinine has been commonly used as a biomarker in researches for children's study on exposure to tobacco smoke. Objective: The overall aim of this study was to determine the association between exposure to SHS with academic and cognitive performance among primary school children. Methodology: This cross-sectional study was conducted at one of the primary school in Serdang. All students in year 5 of the primary school were invited to take part in this study. Parental- administered questionnaire was distributed with the consent form. 72 of the students obtained the permission to participate from n=127 (57% response rate). 68 of students were valid to take part in this study. Methods used to measure the distribution data of exposure to SHS were by the questionnaire and cotinine measurement from saliva samples. Cotinine were analysed using Salimetrics Cotinine ELISA (Enzyme Immunoassay kit). Academic performance which is student's latest examination result was obtained from the school, while cognitive ability was measured using Wechsler Nonverbal Scale of Ability (WNV) test. Results: This study found that 39.7% of respondents lived with a father that smoke and 27.7% of them had a salivary cotinine level exceeding 0.1 ng/ml. There was a significant association between children's daily SHS exposure and salivary cotinine concentration (p<0.05). No significant relationship was found between SHS exposure and academic performance and cognitive ability (P>0.05). Conclusion: This study was a preliminary study, which contributed as baseline data on exposure to secondhand smoke and academic performance as well as cognitive ability among schoolchildren in Malaysia. There was no association between SHS exposure with academic performance and cognitive ability, however, there were clear patterns of higher SHS exposure and poorer academic performance and cognitive ability. This study suggests a further research on exposure to SHS and academic performance in other future study with a larger sample size among a higher sample size population.
