ABSTRACT:Objectives: Paan chewing is a recognized risk factor for oral cancer in the Asian population. However, there is currently little evidence about the intergenerational psychosocial transmission of paan chewing in South Indian families. We investigated the association between parental and participant's paan chewing in a South Indian population.Methods: A subset of data was drawn from a hospital-based case-control study on oral cancer, the HeNCe Life study, conducted at Government Dental and Medical Colleges of Kozhikode, South India. Analyses were based on 371 non-cancer control participants having diseases unrelated to known risk factors for oral cancer. Demographics, behavioural habits (e.g., paan chewing, smoking), and indicators of socioeconomic position (SEP) of both participants and their parents were collected with the use of a questionnaire-based interview and a life grid technique. Unconditional logistic regression assessed odds ratios (OR) and 95% confidence intervals (95%CI) for the associations between parental and participant's paan chewing, adjusted for confounders.Results: Over half of the participants were male (55.2%) and the mean age of participants was 59 (SD=12) years. After adjusting for age, religion, parents' SEP, parents' education, smoking and alcohol consumption, and perceived parenting behaviour we observed that maternal and paternal paan chewing were significantly associated with the participant's paan chewing (OR=2.40, 95%CI=1.11-5.21) and (OR=3.05, 95%CI=1.48-6.27), respectively.
Conclusions:Intergenerational psychosocial transmission of the habit of paan chewing could occur through shared socio-cultural or environmental factors.
