Knowledge of and attitudes towards HIV and risky sexual behaviour among adolescent secondary school students in Bekwarra, NigeriaAdie, Achinyang O. January 2010 (has links)
<p>Aim: The purpose of the study was to assess the knowledge of the transmission and prevention of HIV/AIDS among secondary school students in Bekwarra, Cross River State, Nigeria / to appraise the students&rsquo / attitudes towards HIV/AIDS / to describe the risky sexual and other behaviours they engaged in and what factors influenced such behaviours. This study was conducted in the area to systematically examine the widely held notion that adolescents were deviating from the strict sexual mores of the Bekwarra people, thereby exposing themselves to the risk of acquiring HIV. Methods: Information was collected using a cross-sectional survey based on a 64 item questionnaire adapted from the Family Health International HIV/AIDS/STD Behavioural . Surveillance Surveys. A random sample of 381 male and female students aged 14 to 18 selected from 12 secondary schools participated in the survey. Results: The level of general awareness of HIV/AIDS was high - 56.9% of participants knew how HIV is transmitted - but their knowledge of STI symptoms was low. Only 24.7% knew at least two STI symptoms in women, while only 20.7% knew at least two STI symptoms in men. One hundred and twenty three (32.2%) students constituting 68 males (17.8%) and 55 females (14.4%) had experienced sexual intercourse. The mean age at first sexual experience was 15.06 years for males and 14.95 years for female students. There was a statistical association between age and experience of sexual intercourse (p = .024). Two thirds (65.0%) of the 123 sexually experienced students had intercourse in the last six months, and only 30 of them (24.4%) had used a condom during their last intercourse. The use of condom was most frequent (10.6%) at age 18 and least frequent (.8%) at age 14. About one quarter (26.1%) of the students had taken  / alcohol: 17.3% occasionally, 5.5% moderately, and 2.6% frequently. There was a statistical association between taking alcohol and age (p = .038). Over a half (56.1%) of those who had not had sexual intercourse also had not taken alcohol. In contrast, 14.2% had sexual intercourse and also took alcohol, indicating significant statistical association (p < / .001). 66.8% of the students had neither used drugs nor taken alcohol, whilst 6.8% had both used drugs and taken alcohol, indicating significant association, (p < / .001). There was a similar association between sexual intercourse and using drugs, (p = .002). Conclusions: The study revealed significant high risk sexual behaviour among adolescents in Bekwarra. The high level of risky sexual behaviour and lack of basic knowledge about STIs indicated that access to information is currently insufficient. Health and educational authorities in Bekwarra should utilize the key findings highlighted from this study to design more effective local strategies for sexual health promotion that may help to slow the spread of STIs including HIV/AIDS. Intensive child-friendly programmes for pre-teenagers organized by educators to promote postponement of the early initiation of sexual intercourse may be effective. For adolescents who are unable to control their sexual initiation, improved education on safe sexual practices, especially the use of condoms appears to be necessary.</p>

Assessment of knowledge and attitudes to HIV and sexual risk behaviour among 15-19-year-old learners in Ngong Sub-District, KenyaNjogu, Caroline Njeri January 2011 (has links)
<p>Since the early 1980&rsquo / s when the first case of HIV was diagnosed, AIDS remains a serious and threatening health crisis in the world. Sub-Saharan Africa is the region most affected by the HIV/AIDS pandemic having 67 % of the 33 million people infected with HIV globally in 2007. Young people aged 15-24  / account for an estimated 45% of all new HIV infections worldwide. The study aimed to assess the knowledge and attitudes on HIV/AIDS and sexual  / behavior among 15-19 year olds in Kenya. A descriptive, cross-sectional survey was conducted among 96 students randomly selected from five public  / schools in Ngong sub-district. Descriptive and bivariate analysis was conducted using Epi Info 3.3 and SPSS. The main findings indicate that a third  / (31/96) of respondents were sexually experienced. Knowledge level was however found to be inadequate (below 60 %) indicating a poorly informed sample on knowledge about HIV transmission and prevention. The study showed poor attitudes towards the risk to HIV as only 40 % of both males and females supported the use of condoms even when the sexual partners know each other well. Inaddition, risky sexual behaviors were reported by sexually  /   / experienced respondents where condom use in last sexual intercourse was (57 %) among males and (20 %) among females.</p>

Risky Sexual Behavior among African-American Men Who Have Sex with Men: The Effects of Peer Norms for Condom Use on Risky Sexual Behavior as Moderated by Socio-Demographic, Socio-Contextual, and Health-Related VariablesHolliday, Christopher Scott 03 August 2006 (has links)
This study examined contextual influences on the relationship between peer norms for condom use and risky sexual behavior among African-American men who have sex with men. Analyses assessed the moderating effects of socio-demographic, socio-contextual, and health-related variables. One thousand forty African-American men, who have sex with men, ages 17 to 25 years, were surveyed as part of the Community Intervention Trial for Youth (CITY) from 1999 to 2002 in Atlanta, Georgia. Findings supported the hypothesis that participants who engaged in unprotected insertive anal intercourse, socio-contextual variables moderated the relationship between peer norms and risky sexual behavior. Findings also supported the hypothesis that participants who engaged in unprotected receptive anal intercourse, both socio-demographic variables and a health variable moderated the relationship between peer norms and risky sexual behavior. Findings have implications for intervention, policy, and research, including a need for interventions that recognize the contexts of influence that shape African-American MSM sexual behavior and that support norms for consistent condom use in both steady and casual sexual relationships.

Exploring adolescents' perceptions of risky behaviour using the mobile phone / N. Gois De Gouveia.De Gouveia, Natalie Gois January 2013 (has links)
The aim of this study was to examine adolescent perceptions of risky behaviour using a mobile phone. This research may contribute to creating an awareness of risky and healthy adolescent uses of mobile phones. Anonymous sketches were collected from Grade 10 learners depicting their understanding of risky behaviour using the mobile phone. Thereafter, 12 learners agreed, through informed consent, to participate in semi-structured interviews.
All participants considered the mobile phone an integral part of their social lives. Participants noted the benefits of using their mobile phones for their school work, such as searching the internet, taking photos of, and recordings of class work. Participants indicated that engaging in activities that allow for self-expression using the mobile phone, as well as knowing how much information to post, and using the mobile phone for what it was intended for (i.e. communication), was healthy behaviour. Participants indicated that sharing one’s address, phone number, and personal or intimate photographs and videos was risky behaviour. Participants did not extend their definitions of healthy behaviour to include moderate use of the mobile phone on a daily basis, and in fact reported spending an average of 4-5 hours daily on their mobile phones.
Participants indicated numerous incidents of cyberbullying (although that term was not explicitly used), such as online racism, creating and distributing demeaning lists, and nude or offensive photographs of one another. Participants’ moral boundaries appeared to be negotiable, due to inconsistent opinions on what was considered acceptable or unacceptable behaviour on their mobile phones.
Participants revealed a desire to be trusted with their mobile phones, yet indicated that they hid information from their parents. Findings show that, although the participants knew and understood the risks that exist in mobile interactions, they continued to engage in these risky behaviours. / Thesis (MA (Psychology))--North-West University, Potchefstroom Campus, 2013.

The genetic etiology of human sexualityBrendan Zietsch Unknown Date (has links)
Sexuality is central to our individual lives, our society, and our evolution, but its etiology is not thoroughly understood. Using data from 4904 Australian twins who completed a questionnaire on sexual attitudes and behaviours, I investigated the genetic and environmental influences underlying variation in and covariation between psychological and behavioural aspects of sexuality. Moreover, I explored the role of sexuality traits in several different contexts: evolution, mental health, public health, personality, and problematic behaviour. Before presenting reports of the four main empirical studies in this thesis, I make the case for the importance of studying human sexuality, outline previous findings on the etiology of individual differences in sexuality, and describe the behavioural genetic principles and techniques that were used in the investigations. I also present an additional fifth paper reporting a behavioural genetic analysis of EEG power, which I undertook in order to learn twin data modelling and complex multivariate techniques. In the first empirical paper I investigated sexual orientation from an evolutionary perspective. As sexual orientation is genetically influenced, it is not known how homosexuality, which tends to lower reproductive success, is maintained in the population at a relatively high frequency. I tested the hypothesis that while genes predisposing to homosexuality reduce homosexuals’ reproductive success, they may confer some advantage for heterosexuals who carry them. Results showed that psychologically masculine females and feminine men are 1) more likely to be nonheterosexual, but 2) when they are heterosexual have more opposite-sex sexual partners. Genetic modelling revealed that both these relationships are partly due to pleiotropic genetic influences common to each trait. Further, heterosexuals with a nonheterosexual twin had more opposite-sex partners than do heterosexual twin pairs. Taken together, these results suggest that genes predisposing to homosexuality may confer a mating advantage in heterosexuals, which could contribute to the evolution and maintenance of homosexuality in the population. In the second empirical paper I investigated sexual orientation from the perspective of mental health risk. Large epidemiological studies have shown that homosexuals are at much greater risk of psychiatric disorder than the general population. This has been assumed, with some supporting evidence, to be because of the prejudice and discrimination experienced by homosexuals in a heterosexist society. Here I tested the viability of alternative explanations, using Eysenck’s Neuroticism and Psychoticism scales as markers for psychiatric vulnerability. Firstly, I tested whether apparent sexual orientation differences in psychiatric vulnerability simply mirror sex differences – for our traits, this would predict nonheterosexual males having elevated Neuroticism scores as females do, and nonheterosexual females having elevated Psychoticism scores as males do. The results contradicted this idea, with nonheterosexual men and women scoring significantly higher on both Neuroticism and Psychoticism than their heterosexual counterparts, suggesting an overall elevation of psychiatric risk in nonheterosexuals. Secondly, I used the genetically informative sample to assess the viability of explanations invoking a common cause of both nonheterosexuality and psychiatric vulnerability. We found significant genetic correlations between sexual orientation and both Neuroticism and Psychoticism, but no corresponding environmental correlations, suggesting that if there is a common cause of both nonheterosexuality and psychiatric vulnerability it is likely to have a genetic basis rather than an environmental basis. The third empirical paper investigated the etiology of risky sexual behaviour, which is relevant to public health and welfare through its role in STD transmission and unwanted pregnancies. Results showed that variation in risky sexual behaviour is due to genetic, shared environmental, and unshared environmental influences to approximately equal degrees. The genetic influences partly overlapped with genetic influences on dispositional factors, with significant genetic correlations between risky sexual behaviour and Eysenck’s Impulsivity, Extraversion, Psychoticism, and Neuroticism. This suggests that the genetic influences that shape our personality may also predispose us to risky sexual behaviour. The fourth empirical paper investigated the etiology of a strong association (r = .50) between risky sexual behaviour and adolescent misconduct. Results indicated that the association is due to overlapping genetic and environmental influences, but that in males genes are the primary source of the association whereas in females shared environment plays the greater role. These findings suggest that a general predisposition to risky behaviour may manifest in different potentially harmful ways in adolescence (misconduct) and adulthood (risky sexual behaviour), and that different processes are involved in male and female etiology. Following the empirical reports, I provide a general discussion of my research findings and the study of human sexuality more generally. After summarising the findings and their implications, I then provide a detailed description of potential limitations of the research and to what extent they qualify the conclusions drawn. I also critically discuss the absence of sexuality traits from the major models of personality, and why this and other shortcomings make the personality models inadequate from an evolutionary perspective. Finally, I suggest directions for future research in light of the research and discussion presented in this thesis.

Factorial structure of Driving Log in a Spanish sample / Estructura factorial del Driving Log en una muestra españolaHerrero-Fernández, David, Fonseca-Baeza, Sara, Pla-Sancho, Sara 25 September 2017 (has links)
The present study aimed the adaptation of the Driving Log, a questionnaire that assesses aggressive and risky driving behaviors in a day by day basis, with 395 Spanish participants. Confirmatory factor analysis showed that the questionnaire fitted properly in two correlated factors, labeled as Risky Driving and Aggressive Driving. Subsequent analyses showed that the number of drives is significantly associated to Risky Driving, while the number of occasions in which anger is experimented correlated with Risky Driving as well as Aggressive Driving. Other findings suggest that men behave in a more risky and aggressive mannerthan women. Young people follow this same tendency in comparison to their elders. / El presente estudio tuvo como objetivo la adaptación del Driving Log, un cuestionario que valora los comportamientos agresivos y arriesgados al volante, en una muestra española de 395 personas. El análisis factorial confirmatorio mostró que el cuestionario ajustaba satisfactoriamente en dos factores, etiquetados como Conducción Arriesgada y Conducción Agresiva. Los análisis posteriores mostraron que el número de trayectos realizados se asoció significativamente a la Conducción Arriesgada, mientras que el número de veces en que se experimentó ira lo hizo tanto con la Conducción Arriesgada como con la Conducción Agresiva. Igualmente, se vio que los hombres se comportaban de forma más arriesgada y agresiva que las mujeres, y que los jóvenes lo hacían en mayor grado que los mayores.
