Study examines how genes, gender and environment influence substance abuse [MedicalXpress.com]

Social integration, including strong family ties, can protect one's well-being and even reduce the impact high-risk genes have on health. Scientists call this phenomenon a gene-environment interaction. An Indiana University study focusing on substance abuse, however, found that a three-way interplay of gender, genetics and social integration produced the different outcomes for men and women.

The study looked at men and women with a genetic sensitivity to stressful situations. Strong family and community ties were protective for such men, reducing their risk of abusing alcohol and drugs or using tobacco; but for women with the same genetic sensitivity, the costs associated with strong social ties could outweigh the benefits.
