Background and Aims: Nicotine dependence (ND)-induced anxiety might be
modulated by genetic polymorphisms. The gene-by-environment interaction can be
fitted into the diathesis-stress and differential susceptibility models.
Nevertheless, knowledge of the interaction between adiponectin (ADPN)
polymorphisms and ND on the incident mental disorder is currently scarce. This
study aims to understand the role of ADPN rs266729 on anxiety in
patients with ND while elucidating the psychology model and the various reactions
across genotypes. Methods: We included 315 Chinese males with confirmed
ND, measured using the Fagerstrom test for nicotine dependence (FTND). Anxiety
was assessed using the Self-rating Anxiety Scale. Genomic DNA was extracted and
genotyped from peripheral blood. Hierarchical regression models were used to test
the interactions. Results: There was a significant interaction between
ADPN rs266729 and ND (
