Does Gender Moderate Associations Among Impulsivity And Health-Risk Behaviors?, Scott F. Stoltenberg, Brian D. Batien, Denis G. Birgenheir
Does Gender Moderate Associations Among Impulsivity And Health-Risk Behaviors?, Scott F. Stoltenberg, Brian D. Batien, Denis G. Birgenheir

The present study explores the relations among gender, impulsivity and three health-risk behaviors relevant to young adults (tobacco use, alcohol problems and gambling problems) in a sample of 197 college-age individuals. We sought to determine whether impulsivity is associated with health-risk behaviors in the same ways for men and women. For tobacco use and gambling problems, men were at higher risk than women, and impulsivity was not significantly associated with higher risk. Higher levels of motor impulsivity in men accounted for a significant amount of the gender difference in risk for alcohol problems. That is, impulsivity as measured by the …

Central serotonin dysfunction appears to be related to a subtype of alcoholism with antisocial impulsive features (type II; antisocial alcoholism). The serotonergic deficit may be associated with greater impulsivity, which in turn facilitates both alcohol dependence and antisocial behavior. The present study tested association of antisocial impulsive alcoholism with candidate genes related to serotonergic neurotransmission, using families. Eight markers were assayed using polymerase chain reaction: tryptophan hydroxylase (intron 7), the serotonin transporter SLC6A4 (VNTR 9/12), HTTLPR, the three serotonin receptor types HTR1B (G861C), HTR2A (T102C) and HTR2C (Cys23Ser), monoamine oxidase A (T1460C), and (CA)n. Eligible probands had early age of …

The ability to inhibit a response is an important component of normal behavioral control and is an aspect of psychopathology when diminished. Converging evidence implicates the serotonergic neurotransmitter system in response inhibition circuitry. Objectives — The present study examined potential associations between serotonergic genetic markers and response inhibition as indexed by Stop Task performance. Methods — College-age participants (N= 199) completed self-report questionnaires, the computerized Stop Task, and donated buccal cells for genetic analyses. Statistics were analyzed by ANOVA. Results — Stop Signal reaction time was not associated with allelic variation at a monoamine oxidase A promoter length polymorphism or …
