Adolescence is a critical developmental period in which patterns of health behaviors and overall mental health established during this phase continue through the life course (16) and may affect socioeconomic attainment (17, 18).Moreover, it is also a time of heightened salience for peer networks and influence (19–22).
Analysis of spousal genotypes suggests that spouses are more genetically similar to one another compared with random pairs of individuals in the population (3–9). In previous analyses, we estimated that genetic homogamy was about one-third the magnitude of educational homogamy (3), even when specifically examining education-associated genotypes (8).Add Health surveyed 90,118 US adolescents aged 12–18 in 1994–1995 using a school-based sampling frame.As part of the survey, students were asked to list the names of their friends.Analyses focus on a group of genetically homogeneous respondents identified as being of ancestral European origin (. In step 1, we test whether friends are more genetically similar to one another than to randomly selected peers.In step 2, we ask about the role of school assignment in observed genetic similarity among friends.

Among non-Hispanic whites in Add Health, KING estimates of genetic homophily were about two-thirds the magnitude of our previous KING estimates of genetic similarity among spouses in the US Health and Retirement Study (friend similarity = 0.031, CI = 0.022–0.036, compared with spousal similarity = 0.045 from ref. REAP estimates of genetic similarity were somewhat smaller.
