The effects of smoking cessation on changes in dietary intake

by Crawford, Caroline

Abstract (Summary)
Smoking cessation leads to weight gain but the reason for this gain is not cleariy established. The objective of this study was to compare the mean change in dietary intake arnong quitters and non-quittea enrolled in a smoking cessation program. Mean dietary intake was measured using 24 - hour cal 1 over the telephone at baseline and 6 weeks after the scheduled 'quit date'. Baseline data were obtained from 177 subjects and 130 (73%) were recontacted with complete data. There were 37 quitten (27%). The mean self-reported weight gain among the quitters and non-quitten was 2.4 kg + 3.1 and 0.04 kg I 2.5 respectively (p = 0.00 1). Mean energy intake was the same at baseline between the quitters and non-quitters. There were no statistically significant changes in dietary intake between quitten and non-quitten. Given the high within-individual variability (sd 832) this sample size was only sufficient to detect differences in the change in intake of approximately 460 kcals between quitten and non-quitters. nie Effects Of Smoking Cessation On Changes In Dietan, Inde Résumé Cesser de fumer entraine un gain de poids, mais la raison de ce gain n'est pas clairement établie. L'objectif de cette étude était de comparer le changementmoyen de la prise alimentaireentre les personnes ayant cessé de fumer et celles n'ayant pas cessé aprts avoir suivi un programme pour arrêter de fumer. L'apport nutritionnel moyen a été mesuré à l'aide d'un rappel de 24 heures fait par teléphone au début du programme et 6 à 8 semaines après la date prévue de 'cessation'. Les données de base de 1'7'7 sujets ont été obtenues et 130 (73%)de ceux-ci ont été montacth pour compldterles donnees. En tout. 17personnes (27%) ont cessé de fumer. Le pain de poids moyen rapporté par les personnes ayant arrêté de fumer et celles n'ayant pas arrêt6 etait de 2.4 * 3.1 kg et de 0.04 I 2.5 kg respectivement (p = 0.001). Il n'y a pas eu de changement statistiquement significatif dans la prise alimentaire entre les deux groupes. En raison de la grande variabilitéintra-individuelle(écarttype de 832). l'échantillonnage n'a permis de détecter que des différences d'approximativement 460 kcals entre les personnes ayant cessé de fumer et les autres.
