Pheromonal influences on sociosexual behavior in postmenopausal women

To determine whether a putative human sex-attractant pheromone increases specific sociosexual behaviors of postmenopausal women, we tested a chemically synthesized formula derived from research with underarm secretions from heterosexually active, fertile women that was recently tested on young women. Participants (n = 44, mean age = 57 years) were postmenopausal women who volunteered for a double-blind placebo-controlled study designed, to test an odorless pheromone, added to your preferred fragrance, to learn if it might increase the romance in your life. During the experimental 6-week period, a significantly greater proportion of participants using the pheromone formula (40.9%) than placebo (13.6%) recorded an increase over their own weekly average baseline frequency of petting, kissing, and affection (p = .02). More pheromone (68.2%) than placebo (40.9%) users experienced an increase in at least one of the four intimate sociosexual behaviors (p = .04). Sexual motivation frequency, as expressed in masturbation, was not increased in pheromone users. These results suggest that the pheromone formulation worn with perfume for a period of 6 weeks has sex-attractant effects for postmenopausal women.     

Gender differences in the enactment of sociosexuality: An examination of implicit social motives,sexual fantasies,coercive sexual attitudes,and aggressive sexual behavior

An unrestricted sociosexual orientation (the endorsement of casual sex) has been found to correlate with undesirable behaviors and personality characteristics more so in men than in women. Using a community sample of men and women, we investigated the correlations between sociosexuality and behaviors, motives, attitudes, and fantasies related to sexual aggression. Participants (n = 168; ages 21–45) completed self‐report measures of sociosexual orientation, sexual conservatism, rape myth acceptance, adversarial sexual beliefs, attitudes toward women, sexual behaviors, and perpetration of sexual aggression. Participants also wrote five brief stories that were scored for power and affiliation‐intimacy motives and two sexual fantasies that were coded for the theme of dominance. For both men and women, an unrestricted sociosexual orientation was correlated with behavioral items indicating earlier life experiences with sex, a greater number of lifetime sex partners, and more frequent sexual activity. For men, an unrestricted sociosexual orientation was linked with higher levels of rape myth acceptance and adversarial sexual beliefs; more conservative attitudes toward women; higher levels of power motivation and lower levels of affiliation‐intimacy motivation; and past use of sexual aggression. For women, an unrestricted sociosexual orientation was associated with sexual fantasies of dominance and lower levels of sexual conservatism.

Risky Business: Is There an Association between Casual Sex and Mental Health among Emerging Adults?

A multiethnic sample of single, heterosexual, emerging-adult college students (N = 3,907) ages 18 to 25, from 30 institutions across the United States, participated in a study about identity, culture, psychological well-being, and risky behaviors. Given ongoing debates about the connection between casual sex and psychological adjustment, in the current study we assessed the cross-sectional association of participation in casual sex with psychological well-being and distress. A greater proportion of men (18.6%) compared to women (7.4%) reported having had casual sex in the month prior to assessment. Structural equation modeling indicated that casual sex was negatively associated with well-being (ß = .20, p < .001) and positively associated with psychological distress (ß = .16, p < .001). Gender did not moderate these associations. For emerging-adult college students, engaging in casual sex may elevate risk for negative psychological outcomes.     

Body Size and Sexual Behavior in a Community-Based Sample of Women

ABSTRACT. Women's body size is closely related to their social and sexual experiences. Clinical research has found that women's lifetime sexual behaviors may vary based on body mass index (BMI). Objectives: This study examined the relationship between BMI and recent solo and partnered sexual repertoire in a community-based, non-clinical sample of women. Methods: Two hundred thirty-eight sexually active women completed an online survey measuring age, sexual relationship status, BMI, gender of sexual partners, and engagement in sexual behaviors in the previous 4 weeks. Logistic regression analyses were conducted to determine whether BMI predicted engagement in behaviors after controlling for age and sexual relationship variables. Results: Participant age ranged from 18 to 56 years (M = 30.4, SD = 7.8). Participants were predominantly in exclusive sexual relationships (62.9%, n = 146) with men (82.8%, n = 197). Mean BMI for the sample was 29.33 (SD = 9.28). Participation in self-masturbation, masturbating a partner, performing oral sex on a partner, receiving oral sex from a partner, and penile–vaginal intercourse were not predicted by BMI after controlling for age and partner variables. Conclusions: BMI did not impact sexual repertoire during the previous 4 weeks, with the exception of an increased odds ratio for penile–anal intercourse (OR = 1.06; 95% CI [1.02, 1.10]). Researchers and practitioners working with women should not assume limitations on women's sexual repertoires because of larger body size.     

Outcomes from a homegrown HIV prevention program for extremely high-risk,substance-using men who have sex with men with multiple health disparities

ABSTRACT

From February 2010 through December 2014, 585 substance-using men who have sex with men (MSM) were enrolled into a “homegrown” risk reduction intervention. Participants evidenced significant iterative factor reductions in the odds of substance use including alcohol (AOR = 0.79) and marijuana (AOR = 0.78; both p ≤ 0.05) and marginally significant reductions in the odds of methamphetamine use (AOR = 0.83; p ≤ 0.07). Participants also evidenced significant reductions in sexual risks including the odds of reporting drug/alcohol use before or during sex (AOR = 0.80) and of condomless anal intercourse (AOR = 0.72; all significant at p ≤ 0.05). Results demonstrate that the homegrown intervention was effective at reducing HIV risk behaviors among high-risk MSM.     

Sexual functioning and practices in a multi‐ethnic study of midlife women: Baseline results from swan

This study examined the sexual practices and function of midlife women by ethnicity (African American, Caucasian, Chinese, Hispanic, Japanese) and menopausal status. Sexual behavior was compared in 3,262 women in the baseline cohort of SWAN. Participants were 42 to 52 years old, premenopausal or early perimenopausal, and not hysterectomized or using hormones. Analysis used multivariate proportional odds regression. In our sample, 79% had engaged in sex with a partner in the last 6 months, and a third considered sex to be very important. Common reasons for no sex (n = 676) were lack of partner (67%), lack of interest (33%), and fatigue (16%). Compared with Caucasians, Japanese and Chinese women were less likely, and African Americans more likely, to report sex as very important (p < 0.005). Significant ethnic differences were found for frequency of all practices. Perimenopause status was associated only with higher frequencies of masturbation and pain during intercourse.     

Perceptions of Environmental Supports on the Physical Activity Behaviors of University Men and Women: A Preliminary Investigation

Objective To examine perception differences between genders of university sidewalks and safety from crime on the physical activity (PA) behaviors of undergraduate students. Participants Five hundred and sixty undergraduate students participated in this study. Methods The authors derived questions from the South Carolina Environmental Supports for Physical Activity Questionnaire (SCESPAQ) and National College Health Risk Behavior Survey (NCHRS) PA module. Results The authors found a significant mean difference between genders for the Moderate Intensity Item (eg, walking and biking) and the Flexibility Item, t(558) = 3.602, p = .001, and t(558) = 1.946, p = .050, respectively. Of participants surveyed, 30% of women perceived this campus to be extremely safe compared with 49% of men, t(558) = 4.240, p = .001. Gender and the perceptions of sidewalk presence were significantly related (p < .05) to respondents' walking or bicycling patterns. Conclusions Perceptions of sidewalks and safety from crime on this university campus were related to students' PA behaviors.     

Up and Down or Down and Up? The Process of Change in Constructive Couple Behavior during Traditional and Integrative Behavioral Couple Therapy

Observed positive and negative spouse behavior during sessions of Traditional (TBCT) and Integrative Behavioral Couples Therapy (IBCT) were compared for couples with successful outcomes and their unsuccessful counterparts. One hundred and thirty‐four married chronically and seriously distressed couples (on average in their forties and 80% Caucasian) were randomly assigned to TBCT or IBCT. Trained observers made ratings of 1224 segments from approximately 956 sessions sampled from the course of up to 26 sessions. Multilevel modeling was used to examine change over time. TBCT treatment responders demonstrated a boost‐drop pattern, increasing in constructive behaviors early (more positive behaviors and less negative behaviors) but decreasing later. IBCT responders demonstrated an opposite, drop‐boost pattern, decreasing in constructive behaviors early and increasing later. Patterns were significant for positive behaviors (p < .05) and approached significance for negative behaviors (p = .05). In both treatments, nonresponders showed a significant pattern of decline in positive and increase in negative behaviors over time, although a trend (p = .05) indicates that TBCT nonresponders initially declined in negative behaviors. This study helps clarify the different process of change in two behavioral couple therapies, which may assist in treatment development and provide a guide for therapists in considering behavioral markers of change during treatment.     

Briefly Noted

Researchers have found that mirtazapine, in addition to counseling for substance use, reduced methamphetamine use and some HIV risk behaviors in cisgender men and transgender women who have sex with men. Mirtazapine, an antidepressant also known as Remeron, showed benefits after treatment ended, even if patients didn't always take their medication or took less than they were supposed to. The study follows a previous study of mirtazapine finding reductions in methamphetamine use and sexual risk behaviors among men who have sex with men. “Effects of mirtazapine for methamphetamine use disorder among cisgender men and transgender women who have sex with men: A placebo‐controlled randomized clinical trial” was published in JAMA Psychiatry online last week by Phillip Coffin, M.D. and colleagues. The RCT took place over a course of 24 weeks from 2013 to 2017 in San Francisco. Main outcomes measured were urine tests for methamphetamine and sexual risk behaviors, with sleep, methamphetamine craving, dependence severity, and adverse events also assessed. Sexual risk behaviors included number of sexual partners, and frequency of condomless anal sex. Participants assigned to mirtazapine also had reductions in depressive symptoms.     

Sexual Strategies Across Sexual Orientations

Abstract

The psychological intersection of biological sex, personality, and sexual orientation represents a unique prospect for investigating the evolution of human mating strategies. Evolved sex differences in human psychology may encounter different mating environments within homosexual and heterosexual contexts. The personality traits of homosexuals, if different from heterosexuals, may influence human mating dynamics in revealing ways. In the current study, 5,310 men (5,083 heterosexuals, 131 homosexuals, and 96 bisexuals) and 7,589 women (7,240 heterosexuals, 143 homosexuals, and 206 bisexuals) across four major world regions completed personality and sexuality self-report surveys. Consistent with previous research, sociosexual behavior (e.g., number of one-night stands) and personality traits (e.g., masculinity and openness to experience) varied across sexual orientation. In addition, personality traits were predictably related to sociosexual behavior. However, variability in personality traits did not account for the observed differences in sociosexual behavior across sexual orientation.     

What Behaviors Do Young Heterosexual Australians See in Pornography? A Cross-Sectional Study

This study investigated how frequently a group of young heterosexual Australians (ages 15 to 29) saw a range of behaviors represented in pornography over the previous 12 months. Participants were recruited to an anonymous online survey. Those who reported having viewed pornography in the past 12 months (n = 517) indicated how frequently they saw each of a list of 17 behaviors when they watched pornography in the past 12 months. Men’s pleasure (83%) was seen frequently by the highest proportion of young people surveyed, followed by a man being portrayed as dominant (70%). Women were more likely to report frequently seeing violence toward a woman (p < 0.01). Men were more likely to report frequently seeing heterosexual anal sex (p < 0.01), ejaculation onto a woman’s face (p < 0.01), women portrayed as dominant (p < 0.01), a man being called names or slurs (p < 0.01), and violence toward a man that appears consensual (p < 0.01). Younger age was significantly associated with frequently seeing women’s pleasure (p < 0.05), violence toward women which appeared consensual, and all types of violence (p < 0.01). Older age was associated with frequently seeing men’s pleasure (p < 0.01) and heterosexual anal sex (p < 0.05). Our findings draw attention to the gendered ways that behaviors in pornography are seen and identified by young heterosexual audiences.     

Exploring Dimensions of Racism,Homophobia, and Social Network As Concomitant Predictors of Condom Use in a Sample of Black MSM

With a convenience sample of 148 Black men who have sex with men (MSM) who primarily resided in the Washington, District of Columbia, metropolitan Area, the purpose of this research was to concomitantly use dimensions of racism, homophobia, and social network constructs in a regression model to predict condom use. In the model, analysis indicated that condom nonusers versus consistent users experienced more conversations with friends regarding salient topics (i.e., HIV status) (odds ratio [OR] = .86, p < .01) and fewer discussions with sexual partners about salient topics (OR = .77, p = .02). Furthermore, inconsistent condom users versus consistent users experienced higher levels of internalized homophobia (OR = 1.12, p = .04) and less racism associated with physical characteristics (OR = .89, p = .04). Notably, all of the racism dimensions identified in this research were nonsignificant as positive predictors of condom use. Overall, based on the findings, internalized homophobia may need to be isolated or targeted as an HIV-risk factor when implementing individual- and group-level HIV-prevention strategies for Black MSM. Moreover, improved communication skills among Black MSM pertaining to discussing salient topics (i.e., HIV status) with their sexual partners could also be used as a possible HIV-prevention strategy.     

Use of Drinking Protective Behavioral Strategies and Sexual Perceptions and Behaviors in U.S. College Students

Alcohol use among college students is linked to an increased likelihood of engaging in risky sexual behaviors, including casual sex and unprotected sex. These behaviors increase college students' risks for negative social and health-related consequences. This study examined the relationship between drinking behaviors and protective behavioral strategies (PBS), expectancies and perceptions of sexual risk, and actual alcohol-related sexual behaviors and consequences. Sexually active college students completed Web-based self-report measures of drinking behaviors and use of PBS, alcohol expectancies and perceptions of risk, and sexual behaviors and related consequences (n = 524; 57.1% women). Findings indicated that PBS were related to lower expectancies of sexual risk and sexual disinhibition, and among lighter drinkers, lower expectancies of sexual enhancement from alcohol. PBS were also related to decreased perceptions of sexual-related risks, some alcohol-related sexual behaviors, including number of drinks before/during sex, and number of sexual consequences, but were not related to abstaining during sex, frequency of alcohol-related sexual behaviors, or general condom use. These findings demonstrate a disconnect between perceived and actual risks among college students, such that decreased perceptions of risk may not be associated with protective behaviors. Prevention and intervention implications are discussed.     

College Student Smokers' Cognitive Appraisal of High-Risk Activities

Abstract

Objective: Students who smoke are more likely to engage in risky behaviors such as binge drinking and unprotected sex (Schnieder and Morris, Environ Behav. 1999; 23:575–591). The goals of the present study were to determine whether smokers assess these behaviors as lower risk than nonsmokers, and if smoking rate influences risk perceptions. Methods: Participants were 303 college students. Cognitive Appraisal of Risky Activities (Fromme et al., Cognit Ther Res. 1997; 21:421–442) and smoking were assessed August–November, 2006. Results: Smokers reported significantly less risk, more benefit, and more involvement in risky behaviors than nonsmokers (p < .01). In hierarchical linear regression, risk perceptions moderated the association between smoking and (a) expected benefit from risky sexual behaviors (β = ?1.121, p < .05); and (b) expected involvement with illicit drugs (β = ?.313, p < .01). Conclusions: College smokers’ assessment of high-risk behaviors influenced their intended involvement. Risk perception change may therefore alter their involvement in high-risk behaviors.     

Secondhand Effects of Substance Use for Rural College Students

This pilot study addresses a gap in the research with rural college students by examining substance use secondhand effects for students at a rural northeastern college. Students (N = 157) participated in a web-based survey on their substance use behaviors and their experiences of secondhand effects during the school year. Many students reported experiencing secondhand effects including, 66.9% having cared for an intoxicated student, 52.2% having sleep or study interruption, 33.1% being insulted or humiliated, and 22.9% experiencing an unwanted sexual advance. Compared to men, a greater proportion of women reported experiencing the secondhand effects of: caring for intoxicated others (women 76.7% vs. men 54.9%; χ² = 8.3, df = 1, p = .004), having a serious argument (women 37.2% vs. men 15.5%; χ² = 9.2, df = 1, p = .002), and having sleep or study interrupted (women 59.3% vs. men 43.7%; χ² = 3.8, df = 1, p = .05).     

Frequency of Group Sex Participation and Risk for HIV/STI Among Young Adult Nightclub Scene Participants

Objectives: This study examines frequency of group sex participation and associated characteristics and behaviors among a sample of heterosexual young adult participants in Miami's nightclub scene (n = 498). Methods: Baseline survey assessments were analyzed using zero-inflated binomial regression. Results: Forty-one percent of the sample reported group sex participation history. Greater frequency of group sex is associated with buying sex, sex with an injection drug user, being high during sex, condomless vaginal sex, victimization history, and sexually transmitted infection incidence (p < .02). Conclusions: Sexually transmitted infection prevention and intervention efforts should address risks associated with group sex participation.     

The microanatomy of trabecular bone in young normal and osteoporotic elderly males

Normally there is a gradual continual loss of cortical and trabecular bone in both men and women as they age. Osteopenia and osteoporosis are conditions in which the loss results in brittle bones that fracture easily. Males with low testosterone and hypogonadism are predisposed to osteoporosis and prevention tends to be overshadowed by the greater problem in postmenopausal women. The ability of the skeleton to resist external forces depends partly upon the amount of bone present and partly upon other factors including cancellous bone microarchitecture. This is examined in iliac crest bone biopsies from idiopathic osteoporotic men, mean age 60 ± 12 SD years [n = 16]. These were compared with a healthy control group (autopsy samples), mean age 30 ± 8.9 years [n = 28] with the aim of examining the pattern of cancellous atrophy in male idiopathic osteoporosis. Undecalcified specimens were embedded in methylmethacrylate and prepared for histomorphometry. Sections were analysed using an automated trabecular analysis system (TAS), whereby a binary image was created. Area measurements including the trabecular surface and distance measurements including the trabecular width were made. The binary image was thinned to its medial framework and the node and terminus number as indices of trabecular interconnection were recorded, together with the strut length. Results (median (range)) showed a lower percentage bone volume in the elderly osteoporotic male, 10.2% (5.4–23.1) compared to young normals 25.2% (14.6–43.9), p < 0.001. The trabeculae tended to be thinner, 95.7 µm (66.7–170.7) c.f. 120.8 µm (75.8–208.6) and considerably fewer in number, 11.1 (2.1–31.4) c.f. 48.3 (25.4–66.9), p < 0.001 per field and in particular the number of nodes, 2.1 (0.15–14) c.f. 40.6 (10.3–74.1) per field and the node: terminus ratio fell to 0.13 (0.01–1.19) c.f. controls 0.98 (0.24–6.69), p < 0.001. It was concluded that the pattern of cancellous atrophy in male idiopathic osteoporosis differs from normal aging and resembles that in postmenopausal women. Results using the automated TAS confirm previous observations made manually.     

Predictors of father‐son communication about sexuality

Examining the factors that influence adolescents’ sexual behaviors is crucial for understanding why they often engage in risky sexual behaviors. Using social cognitive theory, we examined predictors of father‐son communication about sexuality. Fathers (N = 155) of adolescent sons completed a survey measuring 12 variables, including self‐efficacy and outcome expectations. We found that (a) son's pubertal development, father's sex‐based values, father's education, father's communication with his father, outcome expectations, and general communication accounted for 36% of the variance in information sharing communication and (b) son's pubertal development, outcome expectations, general communication, and father‐son contact accounted for 20% of the variance in values sharing communication. Study findings can aid professionals in designing guidelines and programs to promote father‐son general communication and sex‐based communication.
