METHODS: As part of the Italian multicenter PEDIGREE study, the PEQ-IT questionnaire was used for prospective data collection. We enrolled subjects under 18 years with PedMS (2013 Krupp criteria) and disease duration ≤ 5 years from onset, along with matched controls.
RESULTS: The study included 114 PedMS cases and 121 controls. Female participants represented 77.2% of cases and 54.4% of controls, with a mean (SD) age of 16.8 (2.7) and 13.5 (4.9) years, respectively. The mean (SD) age at MS onset was 14.2 (2.6) years, and the median EDSS score was 1.0 (range 0-4.0). PedMS risk was higher in subjects with fathers who were current smokers (crude OR 1.94, 95% CI 1.10-3.40) or who smoked 3 months' pre-pregnancy (crude OR 1.79, 95% CI 1.03-3.11). The risk increased when both parents smoked (crude OR 2.03, 95% CI 1.12-3.68) and was highest when both smoked 3 months before pregnancy (crude OR 10.79, 95% CI 1.30-89.54), even after adjustments. No significant association was found with maternal smoking.
CONCLUSION: Parental smoking, particularly paternal smoking current habit and before pregnancy, may increase the risk of PedMS. Promoting smoke-free behaviors among parents could therefore represent a feasible preventive approach to limit early-life environmental factors involved in disease susceptibility.
