Predictive factors for vaginal douching and tampon use among US women: Are these behaviors risk factors for bacterial vaginosis and trichomonas?

The use of feminine products such as vaginal douches, tampons, and sanitary napkins are common among women. Despite the results of some studies that suggest an association between douching and bacterial vaginosis, douching remains a topic that is understudied. The possibility of an association between tampon use and infection has not been significantly investigated since the toxic shock outbreak in the 1980s. The first objective of our study was to evaluate demographic, reproductive health, and sexual behavior variables to establish an epidemiologic profile of menstruating women who reported douching and women who reported using sanitary napkins only. The second objective of our study was to evaluate whether the behaviors of douching and using tampons were associated with an increased risk of bacterial vaginosis or trichomonas. We analyzed these factors, using logistic regression, among the 3,174 women from the NHANES cross sectional data from 2001-2004, who met the inclusion criteria determined for our study. We established an epidemiologic profile for women who had the highest frequency of douching reported as women who were age 36-49, had a high school education or GED, black race, not taking oral contraceptives, reported vaginal symptoms in the last month, two or more sexual partners in the last year, or tested positive for bacterial vaginosis or trichomonas. The profile for those who had the highest frequency of exclusive sanitary napkin use included women with less than a high school education, married women, women classified as black or "other" in race, and women who were not on oral contraceptives. While we were able to establish a significant increase in the odds of douching among women who tested positive for bacterial vaginosis or trichomonas, we did not find any significant difference in the odds of exclusive napkin use and testing negative for bacterial vaginosis or trichomonas.^

THE ROLE OF MUCOSAL EPITHELIAL CELLS IN HIV-1 INFECTION

The predominant route of human immunodeficiency virus type 1 (HIV-1) transmission is infection across the vaginal mucosa. Epithelial cells, which form the primary barrier of protection against pathogens, are the first cell type at these mucosal tissues to encounter the virus but their role in HIV infection has not been clearly elucidated. Although mucosal epithelial cells express only low levels of the receptors required for successful HIV infection, productive infection does occur at these sites. The present work provides evidence to show that HIV exposure, without the need for productive infection, induces human cervical epithelial cells to produce Thymic Stromal Lymphopoietin (TSLP), an IL7-like cytokine, which potently activated human myeloid dendritic cells (mDC) to cause the homeostatic proliferation of autologous CD4+ T cells that serve as targets for HIV infection. Rhesus macaques inoculated with simian immunodeficiency virus (SIV) or with the simian-human immunodeficiency virus (SHIV) by the vaginal, oral or rectal route exhibited dramatic increases in: TSLP expression, DC and CD4+ T cell numbers, and viral replication, in the vaginal, oral, and rectal tissues, respectively within the first 2 weeks after virus exposure. Evidence obtained showed that HIV-mediated TSLP production by cervical cells is dependent upon the expression of the cell surface salivary agglutinin (SAG) protein gp340. Epithelial cells expressing gp340 exhibited HIV endocytosis and TSLP expression and genetic knockdown of gp340 or use of a gp340-blocking antibody inhibited TSLP expression by HIV. On the other hand, gp340-null epithelial cells failed to endocytose HIV and produce TSLP, but transfection of gp340 resulted in HIV-induced TSLP expression. Finally, HIV-induced TSLP expression was found to be mediated by TLR7/8 signaling and NF-kB activity because silencing these pathways or use of specific inhibitors abrogated TSLP expression in gp340-postive but not in gp340-null epithelial cells. Overall these studies identify TSLP as a key player in the acute phase of HIV-1 infection in permitting HIV to successfully maneuver the hostile vaginal mucosal microenvironment by creating a conducive environment for sustaining the small amount of virus that initially crosses the mucosal barrier allowing it to successfully cause infection and spread to distal compartments of the body

The performance of human papillomavirus high-risk DNA testing in the screening and diagnostic settings.

OBJECTIVE: We sought to evaluate the performance of the human papillomavirus high-risk DNA test in patients 30 years and older. MATERIALS AND METHODS: Screening (n=835) and diagnosis (n=518) groups were defined based on prior Papanicolaou smear results as part of a clinical trial for cervical cancer detection. We compared the Hybrid Capture II (HCII) test result with the worst histologic report. We used cervical intraepithelial neoplasia (CIN) 2/3 or worse as the reference of disease. We calculated sensitivities, specificities, positive and negative likelihood ratios (LR+ and LR-), receiver operating characteristic (ROC) curves, and areas under the ROC curves for the HCII test. We also considered alternative strategies, including Papanicolaou smear, a combination of Papanicolaou smear and the HCII test, a sequence of Papanicolaou smear followed by the HCII test, and a sequence of the HCII test followed by Papanicolaou smear. RESULTS: For the screening group, the sensitivity was 0.69 and the specificity was 0.93; the area under the ROC curve was 0.81. The LR+ and LR- were 10.24 and 0.34, respectively. For the diagnosis group, the sensitivity was 0.88 and the specificity was 0.78; the area under the ROC curve was 0.83. The LR+ and LR- were 4.06 and 0.14, respectively. Sequential testing showed little or no improvement over the combination testing. CONCLUSIONS: The HCII test in the screening group had a greater LR+ for the detection of CIN 2/3 or worse. HCII testing may be an additional screening tool for cervical cancer in women 30 years and older.

A study of factors regulating the autonomous proliferation of the steroid hormone-induced LJ6195 murine reproductive tract tumor

Neonatal estrogen treatment of BALB/c mice results in the unregulated proliferation of the cervicovaginal epithelium and eventually tumorigenesis. The conversion of the normally estrogen responsive cyclic proliferation of the vaginal epithelium to a continuous estrogen-independent pattern of growth is a complex phenomenon. The aim of this study was to gain an understanding of the mechanism(s) by which steroid hormone administration during a critical period of development alters the cyclic proliferation of vaginal epithelium, ultimately leading to carcinogenesis in the adult animal.^ The LJ6195 murine cervicovaginal tumor was induced by treating newborn female BALB/c mice with 20 $\mu$g 17$\beta$-estradiol plus 100 $\mu$g progesterone for the first 5 days after birth. In contrast to proliferation of the normal vaginal epithelium, proliferation of LJ6195 is not regulated by estradiol. Northern blot analysis of RNA from vaginal tracts of normal mice, neonatal-estrogen treated mice, and LJ6195 indicate that there is an alteration in the expression of several genes such as the estrogen receptor, c-fos, and HER2/neu. In response to neonatal estrogen treatment, the estrogen receptor is down regulated in the murine vaginal tract. Therefore, the estrogen-independent nature of this tissue is established as early as 3 months after treatment. There is strong evidence that the proliferation of LJ6195 is regulated through an autocrine growth pathway. The LJ6195 tumor expresses mRNA for the epidermal growth factor receptor. In addition, conditioned medium from the LJ6195 tumor cell line contains a growth factor(s) with epidermal growth factor-like activity. Conditioned medium from the LJ6195 cell line stimulated the proliferation of the EGF-dependent COMMA D mouse mammary gland cell line in a dose-dependent manner. The addition of an anti-mEGF-antibody to LJ6195 cell cultures significantly decreased growth. These results suggest that the EGF-receptor mediated growth pathway may play a role in regulating the estrogen-independent proliferation of the LJ6195 tumor. ^

Anthropometric measures as a predictor of cephalopelvic disproportion

This study compared three body measurements, height, hip width (bitrochanteric) and foot length, in 120 Hispanic women who had their first birth by cesarean section (N = 60) or by spontaneous vaginal delivery (N = 60). The objective of the study was to see if there were differences in these measurements that could be useful in predicting cephalopelvic disproportion. Data were collected from two public hospitals in Houston Texas over a 10 month period from December 1994 to October 1995. The statistical technique used to evaluate the measures was discriminant analysis.^ Women who delivered by cesarean section were older, shorter, had shorter feet and delivered heavier infants. There were no differences in the bitrochanteric widths of the women or in the mean gestational age or Apgar scores of the infants.^ Significantly more of the mothers and infants were ill following cesarean section delivery. Maternal illness was usually infection; infant illness was primarily infection or respiratory difficulties.^ Discriminant analysis is a technique which allows for classification and prediction to which group a particular entity will belong given a certain set of variables. Using discriminant analysis, with a probability of cesarean section 50 percent, the best combination to classify who would have a cesarean section was height and hip width, correctly classifying 74.2 percent of those who needed surgery. When the probability of cesarean section was 10 percent and probability of vaginal delivery was 90 percent, the best predictor of who would need operative delivery was height, hip width and age, correctly classifying 56.2 percent. In the population from which the study participants were selected the incidence of cephalopelvic disproportion was low, approximately 1 percent.^ With the technologic assistance available in most of the developed world, it is likely that the further pursuit of different measures and their use would not be of much benefit in attempting to predict and diagnose disproportion. However, in areas of the world where much of obstetrics is "hands on", the availability of technology extremely limited, and the incidence of disproportion larger, the use of anthropometric measures might be useful and of some potential benefit. ^

Birth defects among surviving children under seven years of age in Tianjin, China

Birth defects are a leading cause of infant mortality in the developed countries. They are also of increasing concern in many developing countries, such as China. However, prevalence and causes of birth defects in China are inadequately understood.^ The purpose of the present study was to estimated prevalence of birth defects in surviving children under seven years of age in Tianjin, China and investigate determinants of birth defects in the study area.^ The present study took place in Tianjin, China in 1986, involving 22,081 surviving children under seven years of age. Children with birth defects were ascertained through physical examinations by physicians during household visits and ascertainment of birth defects was verified through multiple sources. Of 22,081 surviving children, 524 had birth defects (23.7 per 1,000). The study noted a striking discrepancy in the prevalence of birth defects between urban and rural area. The prevalence of birth defects was 16.3 per 1,000 in the urban and 33.2 per 1,000 in the rural area.^ Using cases of birth defects ascertained from surviving children, a case-control study was carried out. The study observed that first-trimester maternal flu was associated with increased risk of both major and minor birth defects in children after controlling for other maternal factors (adjusted odds ratio (OR) = 8.7, 95% confidence interval (CI) = 4.3-17.3; OR = 3.6, 95% CI = 1.7-7.5). This association could be biased by different reporting of exposure between mothers of children with birth defects and mothers of children without defects. This study indicated that maternal flu was also associated with congenital heart defects and polydactyly after controlling for other maternal factors (adjusted OR = 32.3, 95% CI = 13.3-78.3; adjusted OR = 5.5, 95% CI = 1.1-27.7). The associations remained when affected controls (children with similar birth defects other than congenital heart defects or polydactyly) were used (adjusted OR = 4.3, 95% CI = 1.2-15.3; OR = 1.4, 95% CI = 1.4-7.9). A weak association between first-trimester vaginal bleeding and selected groups of birth defects was found in this study, but the association may be confounded by other factors. Maternal smoking during pregnancy was modestly associated with cleft lip with or without cleft palate (OR = 1.4, 95% = 0.4-4.9), but the association may be due to chance. Some major limitations in this study warrant caution in interpretation of the findings, especially the causal relation. ^

Developmental effects of estrogen and PCBs in the reproductive tract of BALB/C mice

Many of the tumorigenic effects that result from neonatal exposure to both natural and synthetic estrogens resemble those found in humans exposed to diethylstilbestrol (DES) in utero. Using this established DES neonatal mouse model, my goal was to investigate long-term molecular and morphological effects of certain polychlorinated biphenyls (PCBs) that are weakly estrogenic in adult mice. Focusing on the cervicovaginal (CV) tract, since this is where tumors develop in the BALB/c mouse, I first assessed the 17β-estradiol (E2) dose-response for expression of lactoferrin (LTF). LTF is a highly inducible estrogen biomarker that is permanently altered in uteri from neonatally treated mice. Treatments were administered via 5 subcutaneous injections beginning within 16 hrs after birth, days 1–5. ^ The ontogeny of LTF expression from mouse CV tracts was determined by examining three different stages of life: pups, immature, and mature mice. Northern RNA analysis and immunohistochemistry showed that neonatal E 2 treatment both increases and decreases LTF expression. Early expression of LTF in the CV tract at all doses occurred in pups. In both immature and adult mice, increased LTF expression was dependent on whether E2 induced ovary-dependent or ovary-independent persistent vaginal cornification. ^ Next, I studied biological responses from neonatally PCB exposed adult mice. As expected, using a neonatal uterine bioassay I showed that 2 ′4′6′-trichloro-4-biphenylol (OH-PCB-30), 2′3′4′ 5-tetrachloro-4-biphenyloI (OH-PCB-61), and OH-PCB-30/61 (50/50 mixture), were estrogenic causing a dose-dependent increase in uterine weight. ^ Long-term effects of OH-PCB 30 [200 μg/pup/day] were most similar to E2 as seen by an increased uterine wet weight in day 50 mice similar to E2 [5 μg/pup/day] (141% and 140% of control, respectively). Another similarity between OH-PCB 30 and E2 neonatally treated mice was found in those sacrificed at 20 months of age. At these same doses CV tract squamous cell carcinoma induction was 43% of E2 treated mice and 47% of OH-PCB 30 treated mice. Differences were noted in adenoaquamous; cell carcinoma development, where 16% of OH-PCB-30 neonatally treated mice developed tumors versus 8% for E2. Based on these results using the neonatal mouse model, I conclude that the OH-PCBs tested are strongly estrogenic and tumorigenic showing dose-response relationships when exposure occurs during development of the reproductive tract in mice. These results may have important implications for risk assessment in determining the effects of xenoestrogens exposure early versus later in life. ^

Diagnosis of sexually transmitted infections in developing nations using syndromic management: Is it working?

Sexually transmitted infections (STIs) are a major public health problem, and controlling their spread is a priority. According to the World Health Organization (WHO), there are 340 million new cases of treatable STIs among 15–49 year olds that occur yearly around the world (1). Infection with STIs can lead to several complications such as pelvic inflammatory disorder (PID), cervical cancer, infertility, ectopic pregnancy, and even death (1). Additionally, STIs and associated complications are among the top disease types for which healthcare is sought in developing nations (1), and according to the UNAIDS report, there is a strong connection between STIs and the sexual spread of HIV infection (2). In fact, it is estimated that the presence of an untreated STI can increase the likelihood of contracting and spreading HIV by a factor up to 10 (2). In addition, developing countries are poorer in resources and lack inexpensive and precise diagnostic laboratory tests for STIs, thereby exacerbating the problem. Thus, the WHO recommends syndromic management of STIs for delivering care where lab testing is scarce or unattainable (1). This approach utilizes the use of an easy to use algorithm to help healthcare workers recognize symptoms/signs so as to provide treatment for the likely cause of the syndrome. Furthermore, according to the WHO, syndromic management offers instant and legitimate treatment compared to clinical diagnosis, and that it is also more cost-effective for some syndromes over the use of laboratory testing (1). In addition, even though it has been shown that the vaginal discharge syndrome has low specificity for gonorrhea and Chlamydia and can lead to over treatment (1), this is the recommended way to manage STIs in developing nations. Thus, the purpose of this paper is to specifically address the following questions: is syndromic management working to lower the STI burden in developing nations? How effective is it, and should it still be recommended? To answer these questions, a systematic literature review was conducted to evaluate the current effectiveness of syndromic management in developing nations. This review examined published articles over the past 5 years that compared syndromic management to laboratory testing and had published sensitivity, specificity, and positive predicative value data. Focusing mainly on vaginal discharge, urethral discharge, and genital ulcer algorithms, it was seen that though syndromic management is more effective in diagnosing and treating urethral and genial ulcer syndromes in men, there still remains an urgent need to revise the WHO recommendations for managing STIs in developing nations. Current studies have continued to show decreased specificity, sensitivity and positive predicative values for the vaginal discharge syndrome, and high rates of asymptomatic infections and healthcare workers neglecting to follow guidelines limit the usefulness of syndromic management. Furthermore, though advocate d as cost-effective by the WHO, there is a cost incurred from treating uninfected people. Instead of improving this system, it is recommended that better and less expensive point of care and the development of rapid test diagnosis kits be the focus and method of diagnosis and treatment in developing nations for STI management. ^

Maternal factors, fetal parameters and the risk of shoulder dystocia

Introduction. Shoulder dystocia is a serious complication of vaginal birth, with an incidence ranging from 0.15% to 2.1% of all births. There are approximately 4 million births per year in the United States and shoulder dystocia will be experienced by approximately 20,000 women each year. Although studies have been reported on shoulder dystocia, few studies have addressed both maternal and fetal risk factors. The purpose of this study was to identify maternal and fetal risk factors for shoulder dystocia while proposing factors that could be used to predict impending shoulder dystocia. ^ Material and methods. Articles were reviewed from Medline Pubmed using the search phrase "Risk factors of shoulder dystocia" and Medline Ovid using the search words "Dystocia", "Shoulder" and "Risk factors". Rigorous selection criteria were used to identify articles to be included in the study. Data collected from identified articles were transferred to STATA 10 software for trend analysis of the incidence of shoulder dystocia and the year of publication and a pair wise correlation was also determined between these two variables. ^ Results. Among a total of 343 studies identified, only 20 met our inclusion criteria and were retained for this review. The incidence of shoulder dystocia ranged from 0.07% to 2% and there was no particular trend or correlation between the incidence of shoulder dystocia and year of publication between 1985 and 2007. Pre-gestational and gestational diabetes, postdatism, obesity, birth weight > 4000g and fundal height at last visit > 40cm were identified as major risk factors in our series of studies. ^ Conclusion. Future strategies to predict shoulder dystocia should focus on pre-gestational and gestational diabetes mellitus, postdatism, obesity, birth weight > 4000g and fundal height at last visit > 40cm. ^

Prenatal care programs in a clinic based center in El Paso, Texas: Evaluating outcomes among Hispanic women

Early prenatal care has been found to improve pregnancy and birth outcomes by reducing the risk of low birth weight and preterm births. Statistics point to lower utilization rates of prenatal care in El Paso, Texas and increasing rates of low birth weight. This study was a secondary data analysis, which explored the perceived benefits and barriers known to influence the utilization of prenatal care, and the birth outcomes among participating subjects attending three different prenatal care programs offered at the Centro San Vincent Clinic during the period of December 2006 to February 2008. A survey was used to collect data on demographics and assess perceived benefits and barriers regarding early prenatal care and self-efficacy of the participants. Post-partum birth records were used to gather data about the participant's newborns to include birth weight, gestational age, and the type of delivery (i.e. vaginal versus Cesarean birth). Chi square analysis was conducted to test for significant differences and associations. The sample of women in the study had high risk factors for inadequate utilization of prenatal care. In spite of high demographic risk factors, these women had higher perceived benefits, lower perceived barriers and high self-efficacy associated with prenatal care utilization. The perceived benefits and barriers to prenatal care were associated with place of birth and language preferred, with women from Mexico and who preferred Spanish having higher perceived benefits and lower barriers. There was no significant difference in birth outcomes among the women in different prenatal care programs. The findings of this study suggest that of all participants in the study, those born in Mexico demonstrated higher rates of perceived benefits of early prenatal care. The analysis also suggested that healthy birth outcomes were evenly distributed among women participating in one of the three prenatal care programs. ^

The association between maternal use of spermicides, condoms, intra-uterine devices or progesterone and major structural birth defects

Birth defects occur in 1 of every 33 babies born in the United States, and are the leading cause of infant death. Mothers using contraceptives that become pregnant may continue to use their contraceptives after their first missed menstrual period, thus exposing their baby in utero to the contraceptive product. Progesterone is also sometimes prescribed during the first trimester of pregnancy to mothers with a history of miscarriages or infertility problems. To ensure the safety of these products, it is important to investigate whether there is an increased occurrence of babies born with birth defects to mothers using various contraceptive methods or progesterone in early pregnancy. Using data from the National Birth Defects Prevention Study (NBDPS), an ongoing multi-state, population based case-control study, this study assessed maternal exposures to IUDs, spermicides, condoms and progesterone in early pregnancy. ^ Progesterone used for threatened miscarriage during the first three months of pregnancy was associated with an increased occurrence of hypoplastic left heart (adjusted odds ratios (OR) 2.24, 95% CI 1.13-4.21), perimembranous ventricular septal defects (OR 1.64, 95% CI 1.10-2.41), septal associations (OR 2.52, 95% CI 1.45-4.24), esophageal atresia (OR 1.82, 95% CI 1.04-3.08), and hypospadias (OR 2.12, 95% CI 1.41-3.18). Mothers using progesterone for injectable contraception had increased (OR > 2.5), but insignificant odds ratios for anencephaly, septal associations, small intestinal atresias and omphalocel. Progesterone used for fertility was not associated with an increased occurrence of any birth defects examined. ^ Mothers using progesterone for fertility assistance and threatened miscarriage were very similar with respect to their demographics and pregnancy history. They also both reported similar types of progesterone. Thus, if progesterone was a causal risk factor for birth defects we would have expected to observe similar increases in risk among mothers using progesterone for both indications. Because we predominantly observed increased associations among mothers using progesterone for threatened miscarriage but not fertility assistance, it is possible the increased associations we observed were confounded by indication (i.e. progesterone was administered for vaginal bleeding which occurred as a sequelae to the formation of a congenital anomaly. ^ No significant increased associations were observed between maternal spermicide use during pregnancy and 26 of 27 types of structural malformations. While multiple statistical tests were performed we observed first trimester maternal spermicide use to be associated with a significant increased occurrence of perimembranous ventricular septal defects (OR 2.21, 95% CI 1.16-4.21). A decreased occurrence (OR < 1.0) was observed for several categories of birth defects among mothers who conceived in the first cycle after discontinuing the use of spermicides (22 of 28) or male condoms (23 of 33). ^ Overall the percent of IUD use was similar between mothers of controls and mothers of all cases in aggregate (crude OR 1.05, 95% CI 0.61-1.84). Power was limited to detect significant associations between IUD use and birth defects, however mothers using an IUD in the month immediately prior to conception or during pregnancy were not associated with an increase of birth defects. Limb defects and amniotic band sequence previously reported to be associated with IUD use during pregnancy were not found to occur among any mothers reporting the use of an IUD during pregnancy.^

Psychosocial variables associated with sexual risk behavior among an urban seventh grade population

This dissertation examines the psychosocial factors associated with sexual risk behavior among low socio-economic, minority middle school students in a large urban school district in Houston, Texas and is presented in the form of three articles. Article One examines the association between knowledge, perceived risk of HIV/STD, and self-reported lifetime engagement in vaginal sex among seventh grade students. The purpose of Article Two is to examine the association between knowledge about condoms, condom use attitudes, perceived peer norms about condom use, condom use negotiation self-efficacy, condom use self-efficacy, condom use intentions and actual condom use among seventh grade middle school adolescents. Finally, Article Three examines the association between attitudes, perceived peer norms, refusal self-efficacy about sex, sexual and abstinence intentions among seventh grade adolescents. By providing a better understanding of factors influencing sexual intentions and sexual behaviors among this population, these articles will enable practitioners to develop effective evidence-based interventions to delay sexual initiation and prevent youth from engaging in risky sexual behaviors, including risk of HIV/STDs and unintended pregnancy.^

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.^

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.^

Deployed military women: A second look at gender-specific infections

This descriptive, cross-sectional study addressed the relationship between variables of deployed military women and prevalence of gender-specific infections. The analysis of secondary data will look at the last deployment experience of 880 randomly selected U.S. military women who completed a mailed questionnaire (Deployed Female Health Practice Questionnaire (FHPQ)) in June 1998. The questionnaire contained 191 items with 80 data elements and one page for the subject's written comments. The broad categories of the questionnaire included: health practices, health promotion, disease prevention and treatment, reproduction, lifestyle management, military characteristics and demographics. The research questions are: (1) What is the prevalence of sexually transmitted diseases (STD), urinary tract infections (UTI) and vaginal infections (VI) related to demographic data, military characteristics, behavioral risk factors and health practices of military women during their last deployment? and (2) What are the differences between STD, UTI and VI related to the demographic data, military characteristics, behavioral risk factors and health practices of military women during their last deployment. The results showed that (1) STDs were found to be significantly associated with age and rank but not location of deployment or military branch; (2) UTI were found to be significantly associated with intrauterine device (IUD) use, prior UTI and type of items used for menses management, but not education or age; and (3) VI were significantly associated with age, rank and deployment location but not ethnicity or education. Although quantitative research exploring hygiene needs of deployed women continues, qualitative studies may uncover further “hidden” issues of importance. It cannot be said that the military has not made proactive changes for women, however, continued efforts to hone these changes are still encouraged. Mandatory debriefings of “seasoned” deployed women soldiers and their experiences would benefit leadership and newly deployed female soldiers with valuable “lessons learned.” Tailored hygiene education material, prevention education classes, easy access website with self-care algorithms, pre-deployment physicals, revision of military protocols for health care providers related to screening, diagnosing and treatment of gender-specific infections and process changes in military supply network of hygiene items for women are offered as recommendations. ^
