The effect of family structure on the sexual behaviour choices of female adolescents in South Africa

Student Number : 9904331V - MA research report - School of Social Sciences - Faculty of HumanitiesThe sexual behavioural choices made by adolescents is a salient issue in South Africa. The practice of risky sexual behaviour puts one at risk of unwanted pregnancy, STI and HIV infection. These behaviours affect one not only physically but mentally as well. Adolescence is a “turbulent” time in ones life and risky sexual behaviour makes this period all the more difficult and could result in disastrous consequences. This is due to the fact that sexual health and sexual practices of adolescents has implications for morbidity and mortality rates in South Africa. In order to address the issue of risky sexual behavioural choices made by adolescents, this study has examined the effect of family characteristics on adolescent sexual behavioural choices. The 1998 South African Demographic and Health Survey data was used. The data set was a nationally representative data set with a probability sample of 12000 women aged 15-49 taking part in it. Analysis for this study was based on 2373 female adolescent respondents aged 15-19. The association between individual and family background characteristics and risky sexual behavioural choices was examined. Crucial variables were extracted and fitted to logistic regression models. The study found that 47% of the female adolescents were sexually active. Of these, only 15% used a condom at the last sexual encounter despite the fact that 78% had a high degree of knowledge concerning HIV and condom use. South African adolescents are thus engaging in risky sexual behaviour. The family household structures in which adolescents reside was found to be associated with risky sexual behavioural choices. Sexual activity is strongly associated with socioeconomic status of the family. Condom use and HIV & contraceptive (condom) knowledge was found to be less strongly associated with the socio-economic (financial) status of the family but rather the social processes and relationships within the family are speculated to have a greater effect. The need for a more in-depth analysis with reference to family processes and relationships is recommended in order to properly understand the familial effect on sexual behavioural choices. The findings from this study have implications for reproductive health and reproductive rights policies. Appropriate national strategies are needed to reduce risky sexual practices and thus ensure lower morbidity and mortality among South African youth

Contextual Factors and Sexual Risk Behaviors Among Young, Black Men

Young Black men (YBM), aged 13 to 24 years, face a disproportionate burden of sexually transmitted infections (STIs). STI acquisition among YBM is due to incorrect and inconsistent condom use and is exacerbated by multiple sexual partners. Sexual and reproductive health is influenced by a complex interaction of biological, psychological, and social determinants that contribute to increased risk for STI acquisition. However, there are key social determinants of sexual health that play a major role in adolescent sexual risk-taking behaviors: gender norms, environment, peers, and families as well as a desire to impregnate a woman. Associations between contextual factors (risky environmental context, desire to impregnate a woman, and peer norms supportive of unsafe sex) and sexual risk behaviors were examined among a sample of YBM attending adolescent health clinics. This study used baseline data from a randomized controlled trial (N = 702). Parental monitoring was also examined as an effect modifier of those associations. Sexual risk behaviors were the frequency of condomless vaginal sex, number of sexual partners within the previous 2 months, and lifetime number of sexual partners. Mean age was 19.7. In the adjusted model, peer norms was the only significant predictor for all sexual risk outcomes (p \u3c .05). Parental monitoring was an effect modifier for the perceived peer norms and lifetime sexual partners association (p = .053) where the effect of peer norms on lifetime sexual partners was lower for participants with higher levels of perceived parental monitoring

Courage 2 Test : An Evaluation of a Social Media Marketing Campaign to Increase HIV Testing among Young Black Men

The purpose of this study was to evaluate a social media marketing (SMM) campaign designed to increase HIV testing among young Black men attending a public university in Atlanta, GA. “Courage 2 Test” was a three-month SMM campaign (launched from February 2017 to April 2017) that included targeted Facebook and Instagram advertisements to encourage HIV testing. Students completed an online survey via two cross-sectional samples (n=106 at baseline and n=98 post campaign). Campaign evaluation involved assessing the effects of campaign exposure and the pre/post-grouping variable on ever testing for HIV and testing for HIV in the previous six months via separate logistic regression models. Ever testing for HIV and testing for HIV in the previous six months were higher post campaign (62.2% vs. 39.6%, p=0.001; 35.7% vs. 17.9%, p=0.004, respectively). There were no differences in ever testing for HIV or testing for HIV in the previous six months pre and post campaign launch in multivariable models. There was no statistically significant campaign effect on either HIV testing outcome when controlling for other variables. Although direct campaign exposure was not associated with either HIV testing outcome, ever testing for HIV and testing for HIV in the previous six months were higher post campaign launch compared to the baseline

Correlates of Not Using Antiretroviral Therapy Among Transwomen Living with HIV: The Unique Role of Personal Competence

Purpose: This study tested three psychosocial measures for their potential to serve as counseling goals for promoting ART to transgender women living with HIV (TWLH). Methods: Among 69 TWLH, 17.4% were not taking ART; these volunteers were compared to the remainder using multivariate regression analyses. Results: Only one psychosocial measure achieved significance: Personal Competence (Adjusted Odds Ratio = 0.80, 95% CI = 0.67–0.97, P = 0.02). Because this was a continuous measure, assessed on a 7-point scale, the protective adjusted odds ratio of 0.80 represents a 20% reduction in the odds of not taking ART for each unit of increase in this construct. Conclusion: Findings suggest a potential counseling goal for TWLH not taking ART

Acceptability of Condoms, Circumcision and PrEP among Young Black Men Who Have Sex with Men: A Descriptive Study Based on Effectiveness and Cost

The current study examined and compared the willingness of young Black men who have sex with men (YBMSM) to accept pre-exposure prophylaxis (PrEP), adult male circumcision, and condoms for reducing their risk of HIV acquisition. The majority (67%) reported unprotected receptive anal sex in the last six months. About three-quarters (71%) would accept using PrEP if it was 100% effective. Cost influenced PrEP acceptance with 19% indicating acceptance at $100 per month co-pay. Of those not circumcised, 50$100. About 73% of men were willing to use condoms if they were 100% effective and 50% indicated a willingness at the cost of $10 per month. The findings suggest that condom use promotion strategies should remain at the forefront of public health efforts to control HIV incidence among YBMSM

A theory-based approach to understanding condom errors and problems reported by men attending an STI clinic

The official published version can be accessed from the link below - Copyright @ 2008 Springer VerlagWe employed the information–motivation–behavioral skills (IMB) model to guide an investigation of correlates for correct condom use among 278 adult (18–35 years old) male clients attending a sexually transmitted infection (STI) clinic. An anonymous questionnaire aided by a CD-recording of the questions was administered. Linear Structural Relations Program was used to conduct path analyses of the hypothesized IMB model. Parameter estimates showed that while information did not directly affect behavioral skills, it did have a direct (negative) effect on condom use errors. Motivation had a significant direct (positive) effect on behavioral skills and a significant indirect (positive) effect on condom use errors through behavioral skills. Behavioral skills had a direct (negative) effect on condom use errors. Among men attending a public STI clinic, these findings suggest brief, clinic-based, safer sex programs for men who have sex with women should incorporate activities to convey correct condom use information, instill motivation to use condoms correctly, and directly enhance men’s behavioral skills for correct use of condoms

Psychosocial Mediators of Perceived Stigma and Suicidal Ideation among Transgender Women

BACKGROUND: Transgender women (TGW) in the U.S. experience high rates of stigma, depression, and elevated rates of suicide. This study examined correlates of suicidal ideation and estimated the conditional indirect effects of perceived stigma and psychosocial mediators on suicidal ideation. METHODS: Using a cross-sectional study design, TGW (N = 92) were recruited through snowball sampling in Atlanta, Georgia. Structured interviews were conducted. Suicidal ideation was assessed by combining two variables that measured suicidal thoughts. Logistic regression models were performed to identify the potential risk and protective factors for suicidal ideation. We examined hypothesized psychosocial factors, including anxiety, depression, psychosocial impact of gender minority status, and substance use behaviors as potential mediators for the relationship between perceived stigma and suicidal ideation. All models were controlled for age, race, education, and homelessness. RESULTS: Suicidal ideation was reported by 33% (N = 30) of the study participants. In multivariable analysis, suicidal ideation was associated with sexual abuse (AOR = 3.17, 95% CI = 1.10-9.30), anxiety (AOR = 1.74, 95% CI = 1.10-2.73), family verbal abuse (AOR = 2.99, 95% CI = 1.10-8.40), stranger verbal abuse (AOR = 3.21, 95% CI = 1.02-10.08), and psychosocial impact of gender minority status (AOR = 3.42, 95% CI = 1.81-6.46). Partner support was found to be the protective factor for suicidal ideation (AOR = 0.34, 95% CI = 0.13-0.90). In the mediation analysis, the psychosocial impact of gender minority status mediated the relationship between perceived stigma and suicidal ideation. The estimated conditional indirect effect was 0.46, (95% CI = 0.12-1.11). CONCLUSION: Interventions that aim to reduce suicidal behaviors among TGW should address stigma, psychosocial impact of gender minority status, and different forms of violence and abuse

25 Years of Self-Organized Criticality: Solar and Astrophysics

Shortly after the seminal paper {\sl "Self-Organized Criticality: An explanation of 1/f noise"} by Bak, Tang, and Wiesenfeld (1987), the idea has been applied to solar physics, in {\sl "Avalanches and the Distribution of Solar Flares"} by Lu and Hamilton (1991). In the following years, an inspiring cross-fertilization from complexity theory to solar and astrophysics took place, where the SOC concept was initially applied to solar flares, stellar flares, and magnetospheric substorms, and later extended to the radiation belt, the heliosphere, lunar craters, the asteroid belt, the Saturn ring, pulsar glitches, soft X-ray repeaters, blazars, black-hole objects, cosmic rays, and boson clouds. The application of SOC concepts has been performed by numerical cellular automaton simulations, by analytical calculations of statistical (powerlaw-like) distributions based on physical scaling laws, and by observational tests of theoretically predicted size distributions and waiting time distributions. Attempts have been undertaken to import physical models into the numerical SOC toy models, such as the discretization of magneto-hydrodynamics (MHD) processes. The novel applications stimulated also vigorous debates about the discrimination between SOC models, SOC-like, and non-SOC processes, such as phase transitions, turbulence, random-walk diffusion, percolation, branching processes, network theory, chaos theory, fractality, multi-scale, and other complexity phenomena. We review SOC studies from the last 25 years and highlight new trends, open questions, and future challenges, as discussed during two recent ISSI workshops on this theme.Comment: 139 pages, 28 figures, Review based on ISSI workshops "Self-Organized Criticality and Turbulence" (2012, 2013, Bern, Switzerland

Exploring Individual and Structural Factors Associated with Employment Among Young Transgender Women of Color Using a No-Cost Transgender Legal Resource Center

Purpose: The purpose of this study was to explore individual and structural factors associated with employment among young transgender women (TW) of color. Methods: Sixty-five trans women of color were recruited from the Transgender Legal Defense and Education Fund to complete a 30-min interviewer-assisted survey assessing sociodemographics, housing, workplace discrimination, job-seeking self-efficacy, self-esteem, perceived public passability, and transactional sex work. Results: Logistic regression models revealed that stable housing (structural factor) and job-seeking self-efficacy (individual factor) were significantly associated with currently being employed. Conclusion: Our findings underscore the need for multilevel approaches to assist TW of color gain employment
