Introduction: African American adolescents have a higher prevalence of risky sexual behavior compared to Hispanic and White adolescents. African American adolescents account for 65% of HIV diagnoses among individuals aged 13 to 24 years (Jackson et al., 2015). The rising rate of new STI and HIV cases remains a public health concern and the need for intervention in target populations is outstanding. The objective of this study is to measure the association between alcohol and other substance use and risky sexual behaviors in African American adolescents in the United States. Methods: Data from the Centers for Disease Control and Prevention’s (CDC) 2015 National Youth Risk Behavior Surveillance Survey (YRBS) was used in this study. SAS 9.3 software package was used for descriptive analysis, univariate logistic regression, and multivariate logistic regression of assessing the relationship between alcohol and drug use with risky sexual behaviors in black adolescents in comparison with white adolescents. Results: When controlling for age, gender, and all other variables, African American adolescents that reported ever consuming alcohol were 2.2 (OR=2.2 95% CI=1.6-3.2 p= <.0001) times more likely to ever had sex, 3.8 (OR=3.8 95% CI= 2.9-4.9 p= <.0001) times more likely to have had sex with 4 or more people in the past 3 months, and 1.3 (OR=1.3 95% CI=0.8-2.1 p= <.0001) times more likely to have had sexual intercourse with at least 4 people in their lifetime. When asked if they ever used marijuana, adolescents that reported at least once were 4.5 (OR=4.5 95% CI= 3.2-6.5 p=<.0001) likely to have engaged in sexual intercourse, 3.8 (OR=3.8 95% CI=2.6-5.5 p= <.0001) times more likely to have had sex with four or more people in the past 3 months, and 6.1 (OR=6.1 95% CI=3.7-10.2 p= <.0001) times more likely to have at least 4 sexual partners in their lifetime. Conclusions: The findings of this study indicate that use of illicit substances does increase risky sexual behaviors in African American Adolescents. Further implications of this study can be utilized in the development of intervention programs. Intervention programs should target African American adolescents that engage in risky sexual behaviors and any substance use.

The current study examined the protective effect of parenting-adolescent communication about sex on four risky sexual behaviors (age of onset of sex, number of sex partners, condom use, and STDs) among youth, framed by the Theory of Planned Behavior. It also tested for potential mediation effects between parent-adolescent communication and risky sex measures by sexual cues, date rape attitudes, and acceptance of dating violence in a sample of 2,245 college students from Japan, Slovenia, Spain, and the United States. Results provided evidence of a weak effect of parent-adolescent communication about sex on risky sexual behaviors across samples. A number of cultural influences were also found in the effects by mediators: sexual cues predicted risky sexual behaviors only in the Japanese sample; date rape attitudes was a predictor in the American and Slovenian samples; acceptance of dating violence predicted more risky sexual behaviors only in the American sample; and no significant effects were found in the Spanish sample. Several competing explanations were examined in the discussion to better understand the complex and dynamic interaction between parents and their adolescents as well as the role of culture. More studies are needed to better understand the associations between parent-adolescent communication about sex and risky sexual behaviors.

Master of Science / Department of Family Studies and Human Services / Karen Myers-Bowman / Female adolescent sexual behavior has several potential negative life consequences including: pregnancy, sexually transmitted infection, and HIV/AIDS. Educating parents on how they play a role in the decision-making process regarding the sexual behavior of their adolescent daughters has important implications for Family Life Educators. This thesis explores maternal influence on the risky sexual behavior of female adolescents related to age at first sexual intercourse, contraceptive use, and number of partners. ANOVA was used to explore the relationships between a variety of aspects in the mother-daughter relationship. Findings show there are associations between time spent together, perceptions of closeness, and communication in mother-daughter relationships, and contraceptive use at first and most recent intercourse and total number of partners.

Risky sexual behaviors (RSB) have the potential to negatively impact individuals by increasing the risk of mental health issues, sexually transmitted infections (STIs), and unwanted pregnancies. Adverse childhood experiences (ACEs) and mental health disorders, such as anxiety, PTSD, and depression, have been known to increase RSB. The purpose of this study was to see if these mental health disorders mediate the relationship between ACEs and RSB. Participants (n = 342, mean age = 32) were recruited through social media to complete an online questionnaire. While history of ACEs significantly predicted engagement in RSB as well as all three of the mental health measures, none of the three measures of mental health emerged as a significant mediator of the relationship between ACEs and engagement in RSB (depression: b = .0060, SE = .0568, 95% CI[-.1175, .1148]; anxiety: (b = -.0136, SE = .0565, 95% CI[-.1393, .0904]; PTSD: (b = .1131, SE = .0807, 95% CI[-.0313, .2867]. Ultimately, this research showed that the history of ACEs exerts a strong, direct effect on engaging in RSB, and that in this sample, mental health symptoms are not sufficient to explain this relationship. Therefore, other factors should be explored as possible mechanisms maintaining this relationship. Furthermore, future research efforts should extend this exploration to young participants that may be more likely to participate in RSB.

Among the health disparities affecting the U.S. Hispanic population today are those relating to risky behaviors such as substance abuse, intimate partner violence (IPV) and HIV/AIDS. However, few studies have examined how these conditions may impact this population. The purpose of this dissertation was to explore the experiences that Hispanic women in South Florida have with regard to substance abuse, IPV and risks for HIV/AIDS, to describe how these conditions may be related, and to develop a model that can be used to guide research and interventions targeting this population. This dissertation uses data collected in Project DYVA (Drogas y Violencia en las Americas- Drugs and Violence in the Americas), a pilot research study that utilized both qualitative (Phase I) and quantitative (Phase II) research methods to describe the experiences of Hispanic women in South Florida between the ages of 18 and 60 with regard to substance abuse, violence and risky sexual behaviors. Three studies were conducted as part of this dissertation. The first study utilizes data collected during the qualitative phase of Project DYVA. During this phase eight focus groups were conducted and analyzed using qualitative content analysis (N = 81). The second and third studies utilize data collected during the second phase of Project DYVA. In this phase cross-sectional questionnaires collecting information regarding demographics, acculturation, self-esteem, depression, substance abuse, IPV and risks for HIV, were administered to 82 Hispanic women. Univariate and multivariate statistics were used to explore the relationships between substance abuse, IPV and risk for HIV (study 2) and between resource availability, IPV and depression (study 3). The findings from this dissertation suggest that substance abuse, IPV and risk for HIV are closely related intersecting health issues. IPV, the condition that emerged as the most salient of the three, also appears to be closely associated with resource availability (i.e., self-esteem and income) and depression. Additional individual, cultural, relationship and socio-environmental factors that may play a significant role in shaping the experiences that Hispanic women have with regards to these intersecting conditions were also identified and organized into a model.

<p>A cross- sectional descriptive study using a self-administered close-ended questionnaire was conducted with pupils in standards four to seven (aged 10 &ndash / 17 years) in ten government primary schools in Meru District. The sample of 400 school pupils was obtained by a simple random sampling technique. Data analysis was done using Statistical Package for Social Sciences SPSS (version 15) computer software and the results were presented in frequencies using simple percentages, tables and graphs. The Chi-square test was used to assess the significance where a p-value of &lt / 0.05 was considered statistically significant. In conclusion, Primary school pupils in Meru district engage in several risky sexual behaviors including substance use, sexual coercion, early sexual debut and engaging in various sexual practices. This calls for a more comprehensive approach in the fight against HIV among primary school children in Tanzania, which could include life skill training at an early age, behaviour change communication interventions, advocacy activities to influence policy formulation, condom promotion and incorporating key stakeholders in the rollout of school based HIV programmes such as parents, community leaders and faith-based organizations leaders.</p>
