Validation of an Event-Level, Male Sexual Pleasure Scale (EMSEXpleasure) Among Condom-Using Men in the U.S.

ABSTRACT: Sexual pleasure is a key determinant of condom use. We developed and validated a male, event-level sexual pleasure scale (EMSEXpleasure) among a sample of condom-using men in the U.S. in order to facilitate improved measurement of sexual pleasure. Based on an expert panel process, a 12-item scale was developed. An online sample of 169 men who have sex with men and 162 men who have sex with women were recruited. Factor analysis yielded a two-factor solution that matched domains identified a priori by the expert panel, general pleasure and condom-specific pleasure, indicating internal validity of the instrument. One item was deleted from the scale due to poor validity performance. The overall EMSEXpleasure scale, and each subscale, had high (> 0.8) Cronbach's alpha coefficients, indicating internal reliability. The scale demonstrated convergent validity, with theoretically related constructs associated both with individual scale items and with scale totals. Overall relationship quality (b 3.0, 95% CI 2.0, 4.0), sexual relationship quality (b 2.9, 95% CI 2.0, 4.0), foreplay quality (b 7.5, 95% CI 2, 13), positive feelings about condoms (b 18.8, 95% CI 15, 23), and erection problems while using condoms (b - 17.9, 95% CI - 22, - 14) were associated with the EMSEXpleasure scale in expected directions. The validated EMSEXpleasure event-level scale may be advantageous for future assessments of the ephemeral experience of sexual pleasure, including clinical trials of condoms and other interventions, because it can be used immediately after sex, potentially limiting recall error.

Project description:Sexual networks may place U.S. Black men who have sex with men (MSM) at increased HIV risk.Self-reported egocentric sexual network data from the prior six months were collected from 1,349 community-recruited Black MSM in HPTN 061, a multi-component HIV prevention intervention feasibility study. Sexual network composition, size, and density (extent to which members are having sex with one another) were compared by self-reported HIV serostatus and age of the men. GEE models assessed network and other factors associated with having a Black sex partner, having a partner with at least two age category difference (age difference between participant and partner of at least two age group categories), and having serodiscordant/serostatus unknown unprotected anal/vaginal intercourse (SDUI) in the last six months.Over half had exclusively Black partners in the last six months, 46% had a partner of at least two age category difference, 87% had ≤5 partners. Nearly 90% had sex partners who were also part of their social networks. Among HIV-negative men, not having anonymous/exchange/ trade partners and lower density were associated with having a Black partner; larger sexual network size and having non-primary partners were associated with having a partner with at least two age category difference; and having anonymous/exchange/ trade partners was associated with SDUI. Among HIV-positive men, not having non-primary partners was associated with having a Black partner; no sexual network characteristics were associated with having a partner with at least two age category difference and SDUI.Black MSM sexual networks were relatively small and often overlapped with the social networks. Sexual risk was associated with having non-primary partners and larger network size. Network interventions that engage the social networks of Black MSM, such as interventions utilizing peer influence, should be developed to address stable partnerships, number of partners, and serostatus disclosure.

Project description:BackgroundOne-carbon metabolism, which is crucial in DNA synthesis and genomic stability, is an interrelated network of biochemical reactions involved in several dietary and lifestyle factors. The development of the homocysteine score using these factors may be useful to reflect the status of one-carbon metabolism in large epidemiologic studies without biologic samples to measure homocysteine directly.ObjectiveThe aim of this study was to develop an homocysteine score that reflects one-carbon metabolism better than individual dietary or lifestyle factors.MethodsWe divided 2023 participants with measured plasma total homocysteine data in the Nurses' Health Study and the Health Professionals Follow-Up Study into training (n = 1619) and testing (n = 404) subsets. Using multivariable linear regression, we selected lifestyle determinants of plasma homocysteine in the training set and derived the homocysteine score weighted by the β coefficient for each predictor. The validation of the homocysteine score was assessed using the plasma homocysteine in the independent samples of the training set.ResultsIn the training set, smoking, multivitamin use, and caffeine, alcohol, and dietary and supplemental folate intake were significant independent determinants of plasma homocysteine in multivariable linear regression (P ≤ 0.01) and were included in the derivation of the homocysteine score. The Pearson correlation of the homocysteine score with plasma homocysteine was 0.30 in the testing subset (P < 0.001). The homocysteine score was positively associated with the plasma homocysteine concentration in the testing subset and in an independent population of women; the mean difference of plasma homocysteine concentration between the extreme quintiles of homocysteine score ranged from 0.83 μmol/L to 1.52 μmol/L. Population misclassification either from the lowest quintile of plasma homocysteine into the highest quintile of the homocysteine score or from the highest quintile of plasma homocysteine into the lowest quintile of the homocysteine score was ≤12%.ConclusionThese data indicate that the homocysteine score may be used with relatively inexpensive and simple questionnaires to rank an individual's one-carbon metabolism status when homocysteine data are not available.

Project description:BackgroundThe National Family Planning program of Nepal has introduced the condom as an important family planning method. Despite the continuous effort from the public and private sectors at various levels, its use among youth remains low. Therefore, this study aimed to assess the factors associated with condom use during the last sexual intercourse among male college youth.MethodsWe conducted a cross-sectional study and analyzed the responses of 361 male college youth (aged 19 to 24 years who reported being sexually active preceding six months of the survey), among the 903 participants who reported being involved in vaginal and anal sexual intercourse. The chi-square test was primarily used to find the associated factors and then, stepwise logistic regression was performed by selecting the covariates after the multicollinearity test followed by adjustment of confounders.ResultsWe found that more than one-fourth (27.4%) of the sexually active male youth had used the condoms during their last sexual intercourse. Postgraduate male youth were four times more likely to use the condoms during the last sexual intercourse than undergraduate male youth (AOR = 4.09, 95% CI; 2.08-8.06). Similarly, married youth were less likely to use the condoms during the last sexual intercourse with 95% lower odds than their counterparts (AOR = 0.05, 95% CI; 0.01-0.38). Male youth with adequate knowledge about the condoms were 8 times more likely to use them compared to those with inadequate knowledge (AOR = 8.42, 95% CI; 4.34-16.33). Likewise, male youth with favorable attitude towards the condoms were 2.5 times more likely to use them compared to their counterparts (AOR = 2.58, 95% CI; 1.23-5.42). Similarly, male youth having two or more sex partners were 4.5 times more likely to use the condoms than the youth having only a sex partner (AOR = 4.57, 95% CI; 2.38-8.76).ConclusionThe study concluded that slightly more than one-fourth (27.4%) of male college youth in Kaski district used the condoms during their last sexual intercourse. Level of education, marital status, knowledge about condoms, attitude toward condoms, and number of sex partners are the determinants of condom use among male college youth so recommended for early behavioral interventions, especially in knowledge and attitude. Further studies focusing on including the rural youth and larger geography may help to reach a firmer conclusion.
