Selected AbstractsSexlessness among Married Chinese Adults in Hong Kong: Prevalence and Associated FactorsTHE JOURNAL OF SEXUAL MEDICINE, Issue 11 2009Jean H. Kim ScD ABSTRACT Introduction., Despite recent media coverage in the topic of sexless marriages in East Asia, population-based studies examining the absence of sexual activity among nonelderly married individuals are scant. Previous studies have not simultaneously examined sociodemographic, physiological, and lifestyle predictors of sexless marriages. Aims., To determine the prevalence of past-year sexlessness and the associated factors among the married Chinese adults in Hong Kong. Methods., An anonymous, population-based telephone survey was conducted on 2,846 married Chinese men and women between the ages of 25 and 59 in Hong Kong. Main Outcome Measures., The prevalence of past-year sexlessness and the associated factors and mental health symptoms were examined. Results., The prevalence of past-year sexlessness between the ages of 25,34 years, 35,44 years and 45,59 years was 5.5, 5.1, and 17.0%, respectively, among married males, and 8.3, 12.4, and 31.6%, respectively, among married females. Older age and poor spousal relationship were associated with sexlessness for females, whereas lack of interest in sex, older age, and lower education were significant factors for males. Married women demonstrated statistically significant associations between sexlessness and poorer mental health indicators, such as lower quality of life and being bothered by the unavailability of a sex partner. Conclusions., Sexlessness is prevalent among certain subgroups of urban Chinese couples in Hong Kong, and the large discrepancy in sexlessness between married men and women in each age strata suggests a high prevalence of extramarital relationships. Contrary to commonly held beliefs, there was a stronger association between sexlessness and poorer psychosocial symptoms among married females than males. Sexless marriages are an underappreciated phenomenon among urban Chinese individuals. Kim JH, Lau JTF, and Cheuk KK.

[source] Prevalence and risk factors for hepatitis C virus infection at an Urban veterans administration medical centerHEPATOLOGY, Issue 6 2001Megan E. Briggs This study was designed to determine the seroprevalence and risk factors for hepatitis C virus (HCV) infection in veterans. Anti-HCV testing was performed in 1,032 patients and a questionnaire regarding sociodemographic characteristics and potential risk factors was administered. Adjusted prevalence of unique HCV-positive patients using outpatient services was 17.7% (95% confidence interval [CI] 17.2%, 18.2%). The following risk factors were associated with HCV infection: a history of injection drug use (IDU), receipt of blood transfusion prior to 1992, history of tattoo (odds ratio [OR], 2.93; 95% CI, 1.70-5.08), combat job as a medical worker (OR, 2.68; 95% CI, 1.25-5.60), history of incarceration over 48 hours (OR, 2.56; 95% CI, 1.52-4.32), greater than 15 lifetime sexual partners (OR, 1.61; 95% CI, 0.94-2.76) and sexual relations with a prostitute (OR, 0.46; 95% CI, 0.25-0.82). We concluded that HCV is common in veterans. Risk factors independently associated with infection are IDU, prior transfusion, prior tattoo, combat medical work, incarceration, and multiple opposite sex partners. Infection with HCV among veterans is strongly associated with traditional risk factors for infection and less strongly associated with combat-related risk. [source] Body dissatisfaction and drive for thinness in young adult twinsINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 3 2005Anna Keski-Rahkonen MD Abstract Objective We explored correlates of the Eating Disorder Inventory subscales Body Dissatisfaction (BD) and Drive for Thinness (DT) and genetic and environmental influences on these traits. Method In a population-based sample of 4,667 Finnish twins aged 22,27 years, we conducted twin modeling to explore genetic and environmental contributions to body dissatisfaction and drive for thinness. Logistic regression was used for the correlational analysis. Results Various eating and body size-related factors and psychosomatic symptoms were significantly associated with high body dissatisfaction and drive for thinness in both genders. In women, early puberty onset, early initiation of sexual activity, and multiple sex partners were statistically significant risk factors of body dissatisfaction. In gender-specific univariate twin models, additive genes accounted for 59.4% (95% confidence interval [CI] = 53.2,64.7%) of the variance in body dissatisfaction and for 51.0% (95% CI = 43.7,57.5%) of the variance in drive for thinness among females, but for none of the variance among males. Discussion There are very distinct gender differences in the heritability patterns of body dissatisfaction and drive for thinness in young adults. © 2005 by Wiley Periodicals, Inc. [source] The affective shift hypothesis: The functions of emotional changes following sexual intercoursePERSONAL RELATIONSHIPS, Issue 4 2001MARTIE G. HASELTONU This article develops the Affective Ship Hypothesis, which suggests that women experience positive affective shifts following first-time intercourse as a means to facilitate a longer-term, more committed relationship. The hypothesis predicts a negative affective shift in men who pursue a short-term mating strategy; this shift is hypothesized to function to curtail commitment by motivating the man to terminate the relationship. Study 1 (N= 177) documented sex differences predicted by the affective shift hypothesis. Study 2 (N= 203), using a somewhat different methodology involving reports of presex and postsex feelings, found that men with high numbers of sex partners, but not men with low numbers of partners, experienced a decrease in their partner's physical and sexual attractiveness following first-time sexual intercourse. In contrast, women, more than men, experienced increases in feelings of love and commitment following first-time sex. [source] Sexual Practices, Risk Perception and Knowledge Of Sexually Transmitted Disease Risk Among Lesbian and Bisexual WomenPERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 1 2005Jeanne M. Marrazzo CONTEXT: Sexually transmitted diseases (STDs) can be spread between female sex partners, probably through the exchange of cervicovaginal fluid and direct mucosal contact. Additionally, lesbians have a high prevalence of bacterial vaginosis, which may represent an STD in this population. However, few data on sexual practices or perceived STD risk among lesbians are available to guide development of interventions aimed at reducing the risk. METHODS: To inform the development of a safer-sex intervention for women who have sex with women, focus group discussions were conducted with 23 lesbian and bisexual women aged 18,29. Topics included sexual practices, STD transmission and prevention, and knowledge about bacterial vaginosis. RESULTS: Although six participants had had bacterial vaginosis and three an STD, women reported little use of preventive measures with female partners (washing hands, using rubber gloves and cleaning sex toys). Participants said that vaginal penetrative practices using sex toys and fingers or hands are common, and that partners frequently share sex toys during a sexual encounter, generally without condoms. Knowledge of potential for STD transmission between women, and of bacterial vaginosis, was limited. Participants viewed use of barrier methods (gloves or condoms) as acceptable, provided that there is a reason (usually STD-focused) to use them and that they are promoted in the context of sexual health and pleasure. CONCLUSIONS: Safer-sex messages aimed at lesbian and bisexual women should emphasize the plausibility of STD transmission between women, personal responsibility and care for partners' well-being; should target common sexual practices; and should promote healthy sexuality. [source] Sexual Dysfunction in an Internet Sample of U.S. Men Who Have Sex with MenTHE JOURNAL OF SEXUAL MEDICINE, Issue 9 2010Sabina Hirshfield PhD ABSTRACT Introduction., Relatively little is known about sexual dysfunction (SD) in men who have sex with men (MSM). Aim., In order to better understand SD symptoms in MSM, we assessed self-reported SD symptoms, individually and by latent class analysis (LCA). Methods., In 2004,2005 an Internet sample of U.S. MSM was recruited from gay-oriented sexual networking, chat and news websites. The analytic sample comprised 7,001 men aged 18 or older who reported lifetime male sex partners and oral or anal sex with a male partner in their most recent encounter within the past year. Main Outcome Measures., Seven questions on SD symptoms that occurred during the past 12 months inquired about low sexual desire, erection problems, inability to achieve an orgasm, performance anxiety, premature ejaculation, pain during sex, and sex not being pleasurable. Results., Self-reported symptoms of SD were high. Overall, 79% of men reported one or more SD symptoms in the past year, with low sexual desire, erection problems, and performance anxiety being the most prevalent. Four distinct underlying patterns of sexual functioning were identified by LCA: no/low SD, erection problems/performance anxiety, low desire/pleasure, and high SD/sexual pain. High SD/sexual pain was distinguished from the other patterns by club drug use and use of prescription and non-prescription erectile dysfunction medication before sex in the past year. Additionally, men associated with the high SD/sexual pain group were younger, single, more likely to have poor mental and physical health, and more likely to have been diagnosed with a sexually transmitted infection in the past year compared to men in the no/low SD group. Conclusions., LCA enabled us to identify underlying patterns of sexual functioning among this sample of MSM recruited online. Future research should investigate these distinct subgroups with SD symptoms in order to develop tailored treatments and counseling for SD.

[source] Parent,Daughter Transmission of the Androgen Receptor Gene as an Explanation of the Effect of Father Absence on Age of MenarcheCHILD DEVELOPMENT, Issue 4 2002David E. Comings Based on an evolutionary theory of socialization, Belsky and colleagues proposed that girls exposed to a stressful environment, especially when due to father absence in the first 7 years of life, showed an early onset of puberty, precocious sexuality, and unstable relationships as adults. The authors of this article examined an alternative explanation that a variant X,linked androgen receptor (AR) gene, predisposing the father to behaviors that include family abandonment, may be passed to their daughters causing early puberty, precocious sexuality, and behavior problems. The results of a study of 121 White males and 164 White females showed a significant association of the short alleles of the GGC repeat polymorphism of the AR gene with a range of measures of aggression and impulsivity, increased number of sexual partners, sexual compulsivity, and lifetime number of sex partners in males; and paternal divorce, father absence, and early age of menarche in females. These findings support a genetic explanation of the Belsky psychosocial evolutionary hypothesis regarding the association of fathers' absence and parental stress with early age of onset of menarche and early sexual activity in their daughters. A genetic explanation of the father absence effect is proposed in which fathers carrying the AR alleles are more likely to abandon a marriage (father absence) and pass those alleles to their daughters in whom they produce an earlier age of menarche and behavioral problems. [source] Adult and Pediatric Emergency Department Sexually Transmitted Disease and HIV Screening: Programmatic Overview and OutcomesACADEMIC EMERGENCY MEDICINE, Issue 3 2007Supriya D. Mehta PhD Objectives: To measure the prevalence of gonorrhea, chlamydia, and human immunodeficiency virus (HIV) infection among emergency department (ED) patients who accept screening, and to assess treatment outcomes and risks for infection. Methods: Research staff offered voluntary testing for gonorrhea and chlamydia (by urine transcription-mediated amplification) and HIV (by enzyme immunoassay/Western blot of oral mucosal transudate) to ED patients. Pediatric (15,21 years) and adult (22,29 years) patients were eligible for gonorrhea and chlamydia testing; patients aged 15,54 years were eligible for HIV testing. The authors surveyed behavioral risks of patients accepting HIV testing. Results: From November 2003 to May 2004, 497 of 791 eligible pediatric patients (63%) and 1,000 of 2,180 eligible adult patients (46%) accepted screening for gonorrhea, chlamydia, and/or HIV. There were 41 patients infected with gonorrhea, chlamydia, or both among 380 pediatric patients (10.8%) and 11 of 233 adult patients (4.7%); 14 of 52 patients (27%) were treated presumptively by ED clinicians. Through study efforts, 33 of the 38 remaining patients were treated (90% overall treatment). Eight HIV infections were diagnosed: seven of 969 adult patients (0.7%) and one of 459 pediatric patients (0.2%); five HIV-infected patients (63%) received test results, and three (38%) attended an HIV clinic. Gonorrhea or chlamydia infection in pediatric patients was associated with multiple sex partners, same-sex intercourse, and suspicion of sexually transmitted diseases by the ED clinician. Conclusions: The high prevalence of gonorrhea and/or chlamydia infection among pediatric ED patients tested supports consideration of expanded screening. Targeted HIV screening with rapid tests merits exploration in the authors' ED, given the low-moderate numbers of patients identified through screening, receiving test results, and linked to care.
