Association of part-time employment and sexual risk-taking behaviors among middle school students

Background. Previous research shows inconsistent results as to the association between part-time employment and sexual behavior among younger teens. Studies of older teens cannot be generalized to younger teens because of the wide differences in types of work performed, nature of work environments, and work intensity. Objective. Examine the relationship between part-time employment and sexual behavior in a cross-sectional sample of public middle school students in Houston, Texas. Methods . The study presents a secondary analysis of data from the It’s Your Game…Keep it Real baseline data collection (11/2004–1/2005). It’s Your Game… is an intervention program for middle school students designed to prevent Sexually Transmitted Infections. Statistical analysis. Univariate and multivariate logistic regression analyses were conducted to examine the association between part-time employment and vaginal intercourse: (a) ever had sex; and (b) current sexual activity. Results. Overall, 13.2% of students worked for pay; male students were 1.5 times as likely as females to be working. Of all the students, 11.0% had had sexual intercourse; students who worked were 3 times more likely to be sexually experienced than those who did not. Among students who were sexually experienced, 67.0% were currently sexually active. After adjusting for the other covariates, Hispanic students were almost 3.6 times more likely to report current sexual activity compared to students in other racial/ethnic groups. In univariate analysis, students who worked 1-5 hrs/week were more likely to be sexually experienced than those not currently employed, and the likelihood increased with number of hours worked. There is a similar pattern in the multivariate model, but the odds ratios are too close for the evidence to be more than suggestive. Of sexually experienced students, students working 1-5 hrs/week were 2.7 times more likely to report current sexual intercourse than those not working; those working >5 hrs/week were 4.7 times more likely. The multivariate model showed a similar increase in likelihood, and adjustment for covariates increased these associations: students who worked 1-5 hrs/week were 3.6 times more likely to report current sexual intercourse, and students who worked >5 hrs/week were 4.5 times more likely, than students not currently employed.^

Sexual initiation of U.S. Latino and Colombian high school students: Toward a new theory of adolescent sexuality and implications for sexual health prevention and promotion

The general research question for this dissertation was: do the data on adolescent sexual experiences and sexual initiation support the explicit or implicit adolescent sexuality theories informing the sexual health interventions currently designed for youth? To respond to this inquiry, three different studies were conducted. The first study included a conceptual and historical analysis of the notion of adolescence introduced by Stanley Hall, the development of an alternative model based on a positive view of adolescent sexuality, and the rationale for introducing to adolescent sexual health prevention programs the new definitions of sexual health and the social determinants of health approach. The second one was a quantitative study aimed at surveying not only adolescents' risky sexual behaviors but also sexual experiences associated with desire/pleasure which have been systematically neglected when investigating the sexual and reproductive health of the youth. This study was conducted with a representative sample of the adolescents attending public high schools in the State of Caldas in the Republic of Colombia. The third study was a qualitative analysis of 22 interviews conducted with male and female U.S. Latino adolescents on the reasons for having had or having not had vaginal sex. The more relevant results were: most current adolescent sexual health prevention programs are still framed in a negative approach to adolescent sexuality developed a century ago by Stanley Hall and Sigmund Freud which do not accept the adolescent sexual experience and propose its sublimation. In contrast, the Colombian study indicates that, although there are gender differences, adolescence is for males and females a normal period of sexual initiation not limited to coital activity, in which sexual desire/pleasure is strongly associated with sexual behavior. By the same token, the study about the reasons for having had or not had initiated heterosexual intercourse indicated that curiosity, sexual desire/pleasure, and love are basic motivations for deciding to have vaginal sexual intercourse for the first time and that during adolescence, young women and men reach the cognitive development necessary for taking conscious decisions about their sexual acts. The findings underline the importance of asking pertinent questions about desire/pleasure when studying adolescent sexuality and adopting an evidence-based approach to sexual health interventions.^

Ethnic comparisons of adolescent sexual risk -taking and preventive behavior

For adolescents, unprotected sexual intercourse is the primary cause of sexually transmitted disease (STD), including Human Immunodeficiency Virus (HIV) infection (virus which causes Acquired Immunodeficiency Syndrome (AIDS)), and pregnancy. Although many studies on adolescent sexual behavior have addressed racial/ethnic differences, few studies have examined the relation between race/ethnicity while controlling for other sociocultural and psychosocial variables. The purpose of this study is to examine the relationship between racial/ethnic categories and selected sociocultural and psychosocial variables, with reported adolescent sexual risk-taking and preventive behavior.^ A self-administered questionnaire was used to collect information from 3132 students in a Texas school district (Section 3.5.2). The instrument contained approximately 100 questions on demographic characteristics, sexual behavior, and psychosocial determinants of sexual behavior. Based on the findings of this study, the following major conclusions are made: (1) There are differences in reported sexual risk-taking and preventive behavior among Black, Hispanic and White adolescents in this study. The stratified analysis by gender further suggests significant gender differences in reported sexual behavior among the three racial/ethnic groups. (2) Gender, living arrangement, academic grades, and language spoken at home modified the association between reported sexual risk-taking and preventive behavior and race/ethnicity in this study. This suggests that these sociocultural variables should be considered in future research and practice involving multicultural populations. (3) There are differences in selected psychosocial determinants among the three racial/ethnic groups and between males and females. These differences were consistent with the reported sexual risk-taking and preventive behaviors among race/ethnicity and gender for adolescents in this study. The findings support the consideration of psychosocial determinants in research and interventions addressing adolescent sexual behavior among different racial/ethnic groups.^ Based on the results of this study, two recommendations for practice are made. First, health professionals developing interventions for adolescents from different cultural backgrounds and gender need to be familiar with the specific sociocultural and psychosocial factors which will reduce risky sexual behavior, and promote protective behavior. Second, the need for immediate, realistic, and continuous HIV/STD and pregnancy prevention programs for children and adolescents should be considered. ^

Safer sex choices among African-American college women

The purpose of this dissertation was to explore and describe the factors that influence the safer sex choices of African-American college women. The pandemic of HIV and the prevalence of other sexually transmitted diseases has disproportionately affected African-American females. As young women enter college they are faced with a myriad of choices. Unprotected sexual exploration is one choice that can lead to deadly consequences. This dissertation explores, through in-depth interviews, the factors associated with the decision to practice or not practice safe sex. ^ The first study describes the factors associated with increased sexual risk taking among African-American college women. Sexual risk taking or sex without a condom was found to be more likely when issues of self or partner pleasure were raised. Participants were also likely to have sexual intercourse without a condom if they desired a long term relationship with their partner. ^ The second study examined safe sex decision making processes among a group of African-American college women. Women were found to employ both emotional and philosophical strategies to determine their safe sex behavior. These strategies range from assessing a partner's physical capabilities and appearance to length of the dating relationship. ^ The third study explores the association between knowledge and risk perception as predictors for safer sex behaviors. Knowledge of HIV/AIDS and other STDs was not found to be a determinant of safer sex behavior. Perception of personal risk was also not highly correlated with consistent safer sex behavior. ^ These studies demonstrate the need for risk-based safer sex education and intervention programs. The current climate of knowledge-based program development insures that women will continue to predicate their decision to practice safer sex on their limited perception and understanding of the risks associated with unprotected sexual behavior. Further study into the emotional and philosophical determinants of sexual behavior is necessary for the realistic design of applicable and meaningful interventions. ^

Social capital and adolescent health risk behavior in El Salvador

An emerging body of research suggests that the social capital available in one's social environment, as defined by supportive and caring interpersonal relationships, may provide a protective effect against a number of youth risk behaviors. In exploring the potential protective effect of social capital at school and at home on adolescent health and social risk behavior, a comprehensive youth risk behavior study was carried out in El Salvador during the summer of 1999 with a sample of 984 secondary school students attending 16 public rural and urban schools. The following dissertation, entitled Social Capital and Adolescent Health Risk Behavior in El Salvador, presents three papers centered on the topics of social capital and risk behavior. ^ Paper #1. Dangers in the Adolescent River of Life: A Descriptive Study of Youth Risk Behavior among Urban and Rural presents prevalence estimates of four principal youth risk behavior domains—aggression, depression, substance use, and sexual behaviors among students primarily between the ages of 13 and 17 who attend public schools in El Salvador. The prevalence and distribution of risk behaviors is examined by gender, geographic school location, age, and subjective economic status. ^ Paper #2. Social Capital and Adolescent Health Risk Behavior among Secondary School Students in El Salvador explores the relationship between social resources (social capital) within the school context and several youth risk behaviors. Results indicated that students who perceived higher social cohesion at school and higher parental social support were significantly less likely to report fighting, having been threatened or hurt with a weapon, suicidal ideation, and sexual intercourse than students with lower perceived social cohesion at school and parental social support after adjusting for several socio-demographic variables. ^ Lastly, paper #3. School Health Environment and Social Capital : Moving beyond the individual to the broader social developmental context provides a theoretical and empirical basis for moving beyond the predominant individual-focus and physical health concerns of school health promotion to the larger social context of schools and social health of students. This paper explores the concept of social capital and relevant adolescent development theories in relation to the influence of social context on adolescent health and behavior. ^

Cigarette smoking and cervical intraepithelial neoplasia among colposcopy patients

Epidemiologic and biochemical evidence suggest that smoking is an independent risk factor for cervical neoplasia; however, only two studies have adjusted by the potential confounding effect of human papillomavirus (HPV). To determine the association between self-reported current cigarette smoking and cervical intraepithelial neoplasia (CIN), we conducted a case-control study that controlled for HPV infection and other reported risk factors. The medical records of all new patients referred to the University of Texas M. D. Anderson Cancer Center (UTMDACC) Colposcopy Clinic were reviewed. The study population (n = 564) consisted of all white, black, and Hispanic non-pregnant women who were residents of Texas, and had no history of treatment for cervical neoplasia. Cases (n = 313) included women diagnosed at the UTMDACC with CIN; while controls (n = 251) included those patients diagnosed at the colposcopy clinic as non-CIN (negative 47%, inflammation or atypia 25%, and koilocytosis 27%). Diagnosis was based on a colposcopically directed biopsy in 95% of the subjects, and all subjects were tested for HPV by dot blot hybridization. The crude odds ratio for cigarette smoking and CIN was 1.37 (95% CI 0.97-1.95); however, after adjusting for HPV, age, education, race, number of sexual partners, and age at first sexual intercourse, the odds ratio decreased to 0.91 (95% CI 0.61-1.41). A higher crude odds ratio was observed with CIN 3 (OR = 1.75, 95% CI 1.08-2.83), but this effect also disappeared after adjustment (OR = 1.06, 95% CI 0.57-1.96). Similar results were observed when controlling only for HPV: OR = 1.11 (95% CI 0.77-1.59) for CIN combined and 1.25 (95% CI 0.76-2.08) for CIN 3. These findings suggest that cigarette smoking is not an independent risk factor for CIN in this population, and that HPV may be an important confounding factor for this association. ^

THE INCIDENCE OF PELVIC ENDOMETRIOSIS IN ROCHESTER, MINNESOTA, 1970-1979

The primary objectives of the study were to measure the incidence of pelvic endometriosis among white females of reproductive age (15-49 years) in Rochester, Minnesota, during the period 1970-1979 and to determine the risk of endometriosis by age, marital status, nun status, and educational attainment in this population. An historical prospective design was used. Incident (newly diagnosed) cases were identified from community medical records, and person-years of risk in the study population were estimated from census data.^ Almost two-thirds of the incident cases had surgically verified endometriosis, while the remainder were diagnosed by clinical findings alone. Incidence rates were prepared first with histologically confirmed cases only and then with the successive inclusion of less certain cases: surgically visualized, clinically probable, and clinically possible. On this basis, overall incidence rates were 108.8 to 246.9 newly diagnosed cases per 100,000 person-years. The incidence of pelvic endometriosis was lowest for women 15-19 years of age, increased markedly through age 44, and then declined for women 45-49 years of age. A significantly greater risk of pelvic endometriosis in never married women was detected only when the numerator was limited to histologically confirmed cases. Among never married women 20-49 years of age, no significant difference in the risk of pelvic endometriosis by nun status was detected, but a trend toward a lower incidence in nuns was observed. Women with education beyond high school had a significantly higher incidence of endometriosis than women with less education.^ Cases in the four diagnostic groups differed greatly by age and marital status but were similar with respect to virtually all other characteristics, once age differences were considered. Reproductive history characteristics described included: age of menarche; history of menopause; total pregnancies; ages of first pregnancy, marriage, and sexual intercourse; years from menarche to first intercourse; years of ovulatory cycling; difficulty becoming pregnant; and delay of the first pregnancy by choice. How these characteristics of incident cases differ from those of women free of endometriosis needs to be studied in future research. ^

Club drug use and unprotected anal intercourse among HIV-seronegative men who have sex with men seeking HIV/STD testing at a local STD clinic in Houston

Objective. To explore (1) the association between "club drug" use and unprotected anal intercourse (UAI) and (2) the association between binge drug use and UAI among HIV seronegative men who have sex with men (MSM) seeking HIV/STD testing at a local clinic in Houston. ^ Study design. A sub-sample of 297 HIV seronegative MSM from a cross-sectional study of drug and sexual behavior in Houston was conducted in 2006. Patients who were seeking HIV/STD testing at a local MSM-identified STD clinic were recruited for an anonymous computer-assisted interview. Analysis of identified secondary data consisted of self-reported information about demographic characteristics, use of drugs, and sexual behaviors. ^ Results. With new and casual sex partners, there was a strong and statistically significant association between use of "club drugs" and UAI. No association between binge drug use and UAI was evident. Men aware of HIV seropositivity or unaware of the HIV serostatus of their primary partner were less likely to report UAI. ^ Conclusion. These data suggest that in the Houston area, HIV-negative MSM club drug users, particularly multiple drug users, are at higher risk of UAI than comparable MSMs who do not use club drugs. Episode-level data regarding binge use of these and other drugs, and UAI should be collected in future studies to explore their relationship. The 'new partner' category should be added to sex partner types to measure sex and drug use behaviors in future studies.^ Keywords. HIV-negative MSM; club drugs; unprotected anal intercourse; binge drug use. ^

Parenting practices, acculturation and Hispanic youth's sexual health

This dissertation examined the impact of acculturation and the influence of the family (specifically parenting practices) on Hispanic youth's sexual behavior and reproductive health and is presented in the form of three papers. In the first paper, we assessed the reliability and validity of the Bicultural Acculturation Scale/Language Proficiency (BAS/LP) subscale for use among Hispanic middle school-aged youth. The purpose of the second paper was to examine the associations between initiation of vaginal intercourse, parental monitoring, and parent-child communication while controlling for acculturation and other recognized covariates. Finally, the purpose of the third dissertation paper was to examine HPV vaccine knowledge, attitudes, and acceptability among Hispanic mothers and girls using strategic focus groups. The three papers will jointly extend the knowledge about Hispanic youth and their parents regarding both sexual initiation and uptake of the HPV vaccine. In addition, findings from the papers can inform the development of interventions for Hispanic youth and their parents to delay sexual initiation and increase HPV vaccine uptake.^

Is sexual intimacy among older adults positively associated with mental well-being?

Background. The elderly population aged 60 and above is increasing rapidly throughout the world. The aging process affects physical health of individuals, which in turn affects sexuality and sexual activity. However, many elderly adults continue to engage in one or more forms of sexual activities well into their 70s, 80s, and even in 90s. Despite the widespread stereotypes, misconceptions, and negative attitudes surrounding sexuality in elderly adults, it has been found to be an important aspect of the health of the elderly. However, association between the frequency of sexual activity and mental well being among older adults has not been documented in the literature. ^ Methods. To test the hypotheses that mental well being indicators such as depression, anxiety, and stress were inversely associated with greater frequency of sexual intimacy, a secondary data analysis was conducted using the National Social Life Health and Aging Project (NSHAP) using multivariate logistic regression. The NSHAP was a population-based study that was conducted on a national scale including 1455 men and 1550 women aged 57-85.^ Results. Approximately 1430 (54.1%) of the total population reported being sexually intimate in the past 12 months whereas 1481 (45.9%) participants reported that they did not perform any sexual activity in the past 12 months. In addition, approximately 895(31.1%) participants reported engaging in sexual activity ≥ 2-3 times per month with 665 (78.9%) of these participants reported performing vaginal intercourse only, 14(2.0%) oral sex only, and 89(10.5%) reported performing both vaginal intercourse and oral sex. Controlling for socio-demographic characteristics, frequently (≥2-3 times per month) sexually active participants showed lower odds ratio of depression (OR= 0.60; 95%CI = 0.46, 0.78), anxiety (OR= 0.67; 95% CI= 0.53, 0.86), and stress (OR=0.73; 95% CI = 0.6, 0.88) compared to those who had less frequent sexual activity or who had no sexual activity in the past 12 months.^ Conclusion. Lower levels of depression, anxiety, and stress appear to be associated with greater frequency of sexual activity. Public health interventions should focus on educating elderly adults about their sexual health and how to seek medical help for their sexual problems. Public health professionals should also be educated on how to best assess sexual needs of the elderly adults.^

A comparison of risky sexual behaviors between older and younger men who have sex with men in Houston, TX

Objectives. This study estimated the prevalence of risky sexual behaviors of older (≥ years old) and younger (18-24 years) men who have sex with men (MSM) in Houston, TX and compared the prevalence of these behaviors between the two age cohorts. ^ Methods. Data used in this analysis were from the third MSM cycle of the National HIV Behavioral Surveillance Study. There were 80 older and 119 younger MSM who met the eligibility criteria. Bivariate and Multivariate analysis were performed to compare risky sexual behaviors from the past 12 months and at last sexual encounter between the two age cohorts. ^ Results. OMSM were more likely to be Non-Hispanic White (AOR=4.17; CI: 1.46, 11.89), to have a household income last year greater than $75,000 (AOR=3.59; CI: 1.12, 11.55), and to self-report HIV-positive (AOR=7.35; CI: 2.69, 20.10) than YMSM. OMSM were less like to have had anal sex (AOR=0.11; CI: 0.04, 0.29) or a main sex partner (AOR=0.2; CI: 0.09, 0.45) than YMSM in the past 12 months. Among MSM who had anal sex at last sexual encounter, OMSM were more likely to have not used a condom the entire time regardless of partner type (AOR=3.64; CI: 1.54, 8.61), not used a condom the entire time with a causal sex partner (AOR=7.72; CI: 1.76, 33.92), had unprotected insertive anal intercourse (AOR=2.92; CI: 1.1, 7.75), and used alcohol before or during sex (AOR=5.33; CI: 2.15, 13.2) than YMSM. YMSM and OMSM did not different significantly in knowledge of last sex partner's HIV status. ^ Conclusions. This is not a homogeneous sample of OMSM and risky sexual behaviors vary within the group. There were many similarities in risk behavior between OMSM and YMSM but also some key differences in partner type and condom use indicating a need for increased age-appropriate health promotion programs to limit a potential increase in HIV infection among OMSM. ^
