Children are commonly affected by environmental tobacco smoke. The presence of exposure can be deduced from urinary urine kotinine/creatinine ratio and history. The aim of this study was to investigate passive smoking in healthy children between one-month and five year old, and to determine the adverse effects of passive smoking on child health. Children between one-month and five year old who were regularly monitored for health were included following informed consent given by their parents. The questionnaire method was used. Demographic variables, respiratory tract infections, recurrent infections were questioned. The levels of cotinine, creatinine were measured and the cotinine/creatinine ratios were calculated in urine specimens taken from the children. Growth status and infection frequency were determined using demographic data, cotinine/creatinine ratios in urine, exposure rate to second-hand tobacco smoke of the children. The ratio of household smokers was 70.3%, the ratio of non-smokers was 29.7%. Fifty percent of the mothers were smokers. Urinary cotinine/creatinine ratios were found to be significantly higher in children of smokers compared with children of non-smokers (p=0.011). One third of the children was evaluated as passive smokers. The presence of a smoker at home and the increase in the number of cigarettes smoked during the day increased the frequency of acute respiratory infections (p=0.047). In these regularly-monitored preschool children, we found frequent exposure to cigarette smoke. This study contributes to national data and will aid in increasing the awareness for the deleterious effects of passive smoking on child health.
