The parthogenetic lizard species Cnemidophorus tesselatus is composed of diploid populations formed by hybridization of the bisexual species C. tigris and C. septemvittatus, and of triploid populations derived from a cross between diploid tesselatus and a third bisexual species, C. sexlineatus. An analysis of allozymic variation in proteins encoded by 21 loci revealed that, primarily because of...

Media attention and the literature on lesbian, gay, and bisexual youth overwhelmingly focus on violence involving hate crimes and bullying, while ignoring the fact that vulnerable youth also may be at increased risk of violence in their dating relationships. In this study, we examine physical, psychological, sexual, and cyber dating violence experiences among lesbian, gay, and bisexual youth--a...

INTRODUCTION Research on lesbian, gay, and bisexual (LGB) individuals' health and health practices has primarily consisted of convenience studies focused on HIV/AIDS, substance use, or mental illness. We examined health-related disparities among Oregon LGB men and women compared with heterosexual men and women using data from a population-based survey. METHODS Data from the 2005 through 2008 ...

The number of lesbian, gay, and bisexual (LGB) adults aged 50 and older is projected to reach 5 million in the U.S. by 2030 (Fredriksen-Goldsen, Kim, Shiu, Goldsen, & Emlet, 2015). Older bisexuals experience more negative mental and physical health outcomes when compared to both heterosexuals and other sexual minorities (Fredriksen-Goldsen, Shiu, Bryan, Goldsen, & Kim, 2017). As bisexuals are t...

Previous studies showed sex-specific DNA methylation and expression of candidate genes in bisexual flowers of andromonoecious poplar, but the regulatory relationship between methylation and microRNAs (miRNAs) remains unclear. To investigate whether the methylation of miRNA genes regulates gene expression in bisexual flower development, the methylome, microRNA, and transcriptome were examined in...

OBJECTIVE To provide national estimates for indicators of health-related behaviors, health status, health care service utilization, and health care access by sexual orientation using data from the 2013 National Health Interview Survey (NHIS). METHODS NHIS is an annual multipurpose health survey conducted continuously throughout the year. Analyses were based on data collected in 2013 from 34,5...

All-female species of Poeciliopsis depend upon ~ ~ of closely related species for sperm. This relationship creates a competitive situation in which bisexual ~ ~ compete with unisexual ~ ~ for sperm from ~ ~ of the bisexual species. Earlier studies demonstrated a sufficient mechanism inherent in the behavior of ~ ~ for allowing coexistence in mixed unisexualbisexual populations. Courtship prefer...

OBJECTIVE The study objective was to determine the nature and prevalence of childhood maltreatment experiences among lesbian, gay, and bisexual adults and to compare findings to those obtained from similar heterosexual adults. METHOD Data from the National Survey of Midlife Development in the United States (MIDUS), which measured both childhood experiences with parental emotional and physical...

OBJECTIVES To estimate the number of men in the U.S. military who are gay, bisexual, or other men who have sex with men (MSM) to inform the development of military and other federal policies. STUDY DESIGN We analyzed data from the National Surveys of Family Growth to estimate the number of U.S. men who were gay, bisexual, or MSM, and who had served in the military, compared to those who did n...

The purpose of this study is to determine whether physician knowledge of sexual orientation is associated with increased patient satisfaction in LGB males and females in Milwaukee, Wisconsin. Data were collected during Milwaukee Pride Fest 2007, a festival celebrating lesbian, gay, bisexual, and transgender (LGBT) persons. Chi-squared analyses were then computed to determine if physician knowle...
