Abstract:
Objective To explore the effect of different family tobacco control patterns on cotinine level and acute respiratory infections among infants.Methods A total of 300 infants were included,and were divided into 3 groups based on the tobacco control patterns:strictly tobacco -controlled group (97 cases),partly tobacco -controlled group (88 cases)and tobacco -uncontrolled group (1 1 5 cases).Urinary cotinine was measured in all participants.All participants were prospectively followed -up for 1 year,and the incidence of acute respiratory infections was recorded during the follow-up.Results The cotinine level of strictly tobacco -controlled group [0.45 ±0.21 (μg/L)]was significantly lower than the other two groups [1 .01 ±0.49(μg/L),1 .1 6 ±0.48(μg/L),P <0.05],and no significant differences were detected between the partly tobacco -controlled group and tobacco -uncontrolled group.The incidence of lower respiratory tract infection,not the upper respiratory tract infections,was significant different among the 3 groups (strictly tobacco -controlled group:1 8.75%;partly tobacco -controlled group:32.1 8%;tobacco -uncontrolled group:37.72%)(P <0.05).The number of upper respiratory tract infections and lower respiratory tract infections was significantly different among the three groups.The difference was significant between strictly tobacco -controlled group and partly tobacco -controlled group and between strictly tobacco -controlled group and tobacco -uncontrolled group (P <0.05).Conclusion Strict tobacco control could reduce the prevalence of passive smoking and the incidence of respiratory infections among infants.
