As SMY are comprised of youth who self-identify as gay, lesbian, bisexual (GLB) or who have same-sex attractions or behaviors, our previous finding that different subgroups have different risks for suicidality is understandable. Both are increased in sexual minority youth (SMY). Montoro, Richard Thombs, Brett Igartua, Karine JĬontext Bullying is a known risk factor for suicidality, and suicide is the second leading cause of death for adolescents. Although wide confidence intervals suggest cautious interpretation, the results are consistent with moderate, primarily genetic, familial effects, and moderate to large effects of the nonshared environment (social and biological) on same-sex sexual behavior. 16-.17 for shared environmental, and 64-.66 for unique environmental factors. Corresponding estimates among women were. 00, and the individual-specific environment. 34-.39 of the variance, the shared environment. Biometric modeling revealed that, in men, genetic effects explained. Twin resemblance was moderate for the 3,826 studied monozygotic and dizygotic same-sex twin pairs. The analyses were conducted separately by sex. We performed biometric modeling with data on any and total number of lifetime same-sex sexual partners, respectively. We used data from a truly population-based 2005-2006 survey of all adult twins (20-47 years) in Sweden to conduct the largest twin study of same-sex sexual behavior attempted so far. One reason is that previous studies employed self-selected, opportunistic, or small population-based samples. There is still uncertainty about the relative importance of genes and environments on human sexual orientation. LÃ¥ngström, Niklas Rahman, Qazi Carlström, Eva Lichtenstein, Paul Genetic and environmental effects on same-sex sexual behavior: a population study of twins in Sweden. The elevated level of psychological distress among homosexual individuals, reported in several studies, might-to some extent-be caused by their generally higher levels of childhood GAB as opposed to a homosexual orientation per se. The findings suggest that childhood GAB is related to later distress both among hetero- and homosexual individuals. Only gender typical participants with no same-sex sexual attraction or behavior reported significantly lower levels of symptoms. Both same-sex sexual attraction or behavior and a history of childhood GAB affected the reported levels of current depression and anxiety. Childhood GAB was correlated with negative ratings of parental relationships. Ratings of maternal and paternal over-control and coldness differed as a function of same-sex sexual attraction or behavior. The measures used were retrospective questionnaires. Matched pairs, 79 men (n = 158) and 148 women (n = 296), with equal levels of GAB were created of Finnish participants with either same-sex sexual attraction or behavior and participants without. This study explores the relation between the level of current symptoms of depression and anxiety and recalled childhood gender atypical behavior (GAB), and quality of relationships with parents among men and women who reported same-sex sexual attraction or engaged in same-sex sexual behavior and men and women who did not. Psychiatric symptoms and same-sex sexual attraction and behavior in light of childhood gender atypical behavior and parental relationships.Īlanko, Katarina Santtila, Pekka Witting, Katarina Varjonen, Markus Jern, Patrik Johansson, Ada von der Pahlen, Bettina Kenneth Sandnabba, N
