Association between Sleep Disturbances During Childhood and Smoking Trajectories During Adulthood: The Longitudinal TEMPO Cohort Study

ABSTRACT

Objective

This study examined the longitudinal association between child sleep disturbances from ages 3 to 16 and smoking in adulthood among subjects from a French cohort study.

Methods

Data from 2,134 subjects who participated in the French TEMPO cohort from 1991 to 2018 were used. Sleep disturbances observed from ages 3 to 16 years defined our exposure. Tobacco consumption trajectories constitute our outcomes and were ascertained by using Group-Based Trajectory Modeling, a semiparametric probabilistic method that hypothesizes the existence of distinct developmental trajectories over time within one population. The impact of SDs in childhood on adulthood’s Tobacco consumption were studied using multinomial logistic regression.

Results

Sleep disturbances at 16 years or under were observed in 26.5% of participants. Five smoking trajectories were defined: “non-smokers”, “decrease in consumption at age 20 years”, “low-level tobacco use”, “smoking followed by cessation at age 30 years” and “high-level tobacco use”. No statistically significant association between sleep disturbances and smoking trajectories was found. Compared with nonsmokers, adjusted odds-ratios and 95% Confidence Intervals for each trajectory were respectively: 0.81 [0.52–1.26], 1.28 [0.74–2.22], 1.37 [0.88–2.15] and 1.01 [0.60–1.69].

Conclusion

These results suggest that smoking in adulthood may not be related to sleep disturbances in childhood.
