1. Objectifs

Intentions :
The first article of this thesis has two objectives: «[evaluate] the association between the parental and the participant‘s paan chewing habit and the difference between maternal and paternal contribution in this association [and to investigate] how this intergenerational transmission of the paan chewing habit, in South Indian families, is explained by the participants‘ perception of the relationship with their mothers and fathers.» (p. 91) Cette fiche synthèse se concentre uniquement sur le premier article de cette thèse puisque les autres n’abordent pas la famille.

2. Méthode

Échantillon/Matériau :
L’étude est basée sur les données de la HeNCe Life study qui a eu lieu de 2008 à 2012. Les participants de cette étude provenaient du Canada, de l’Inde et du Brésil. La présente thèse par articles est basée sur les données concernant l’Inde où 350 personnes atteinte du cancer de la bouche et 371 personnes formant un groupe contrôle ont participé.

Instruments :
Questionnaire

Type de traitement des données :
Analyse statistique

3. Résumé

The results of the first article shows that «both the paternal and maternal paan chewing habits were significantly associated with the participant’s paan chewing habit. Moreover, they were similar in effect size; both the paternal and maternal paan chewing habit increased the risk of the participant to start chewing paan, at some point in their lifetime, by approximately 3 times. Participants’ perception of the relationship with their parents only marginally explained this association. However, maternal strictness was significantly associated with the participant’s paan chewing habit. To our knowledge none of the previous studies has investigated this intergenerational transmission in India. However, previous studies, mostly cross sectional surveys, have reported an increased prevalence of paan chewing habit among children of parents who had the habit. Along with peer influence, parental paan chewing has also been proposed as a determinant of initiation based on these survey results. By establishing the association and quantifying the maternal and paternal contributions, our results enrich the knowledge base which could serve as a platform for future studies and in designing interventions targeting parents and children.» (p. 91)
