Filter by:The overall objective of the proposed research is to reduce the incidence of sexually transmitted infections (STIs) among college students. The investigators propose to accomplish this by using the innovative, engineering-inspired multiphase optimization strategy (MOST) to develop a highly effective, appealing, economical, and readily scalable internet-delivered behavioral intervention targeting the intersection of alcohol use and sexual risk behavior. The rate of STIs on college campuses is alarming: one in four college students is diagnosed with an STI at least once during their college experience. Sexual activity when drinking alcohol is highly prevalent among college students. Alcohol use is known to contribute to the sexual risk behaviors that are most responsible for the transmission of STIs, namely unprotected sex, contact with numerous partners, and "hook-ups" (casual sexual encounters). Few interventions have been developed that explicitly target the intersection of alcohol use and sexual risk behaviors, and none have been optimized. In order to reduce the incidence of STI transmission among this and other high-risk groups, a new approach is needed. MOST is a comprehensive methodological framework that brings the power of engineering principles to bear on optimization of behavioral interventions. MOST enables researchers to experimentally test the individual components in an intervention to determine their effectiveness, indicating which components need to be revised and re-tested. Given the high rates of alcohol use and sex among college students, the college setting provides an ideal opportunity for intervening on alcohol use and sexual risk behaviors. The proposed study will include a diverse population of college students on 4 campuses which will increase the generalizability of the findings. The specific aims are to (1) develop and pilot test an initial set of online intervention components targeting the link between alcohol use and sexual risk behaviors, (2) use the MOST approach to build an optimized preventive intervention, and (3) evaluate the effectiveness of the newly optimized preventive intervention using a fully powered randomized controlled trial (RCT). This work will result in a new, more potent behavioral intervention that will reduce the incidence of STIs among college students in the US, and will lay the groundwork for a new generation of highly effective STI prevention interventions aimed at other subpopulations at risk.
This study has two aims: a) to evaluate the pelvic floor muscles strength in primigravid and non-pregnant nulliparous women and to correlate with their sexual function and b) to compare PFM strength and sexual function between women in the second and third pregnancy trimesters.
Many women and men in fertile age are at risk for sexual transmitted infections and unwanted pregnancies, and have insufficient knowledge of health promoting lifestyle prior to conception. There is a need to increase awareness among people in fertile age about how sexual risk-taking and unhealthy lifestyle can negatively affect fertility and pregnancy outcomes. Previous studies on preconception health and care have mainly focused on women. The aim of our study was to investigate if Reproductive Life Plan-based counseling with a midwife could increase men's reproductive knowledge. The second aim was to evaluate men's experiences of the intervention.
The purpose of this study is to: 1. test the effect of a smartphone enhanced LETS ACT (LETS ACT-SE) on frequency of substance use 2. use functional magnetic resonance imaging (fMRI) to test the relationship between neuromarkers of reward sensitivity on frequency of substance use.
The Haitian American Responsible Teen (HART) afterschool program, a cultural adaptation of the BART curriculum, will provide an HIV/AIDS curriculum adapted to Haitian students that consists of eight sessions lasting approximately two hours each over a twelve- week period. The comparison group will receive a nutrition intervention during the same time period. The primary goals of the evaluation are to determine the effectiveness of the HART program on delaying initiation of sexual intercourse, reducing number of sexual partners, and increasing "abstinent" behavior and contraception use among those who were sexually experienced at baseline. Over a five semester period, the programs will be implemented in 7 or more schools in the greater Boston area, with offerings in the fall, the spring and summer, among approximately 780 male and female Haitian students. The programs will recruit 9th & 10th grade Haitian students who will range in age from 13 to 19 years old. We will implement a randomized controlled trial in which each semester, students within schools will be stratified by gender and then randomly assigned to participate in the HART or the nutrition condition. Students will be recruited annually and enrolled until the summer of 2015. During the spring and summer of 2012, 120 youth will be randomly assigned to a treatment condition. During year three, 180 youth will be randomly assigned to condition each semester (360 youth total during Year 3). During year four, 180 youth will be randomly assigned in the first semester, and 120 youth will be randomly assigned in the second semester (300 youth total during Year 4). The number of times student-level randomization will occur and the number of groups formed will vary depending on the size of the 9th and 10th grade Haitian population served in each school.
The investigators have designed a single site, Phase IV open label, prospective observational clinical trial to compare the effect of immediate postpartum Nexplanon placement (IPP) versus standard postpartum contraceptive care (control) on consistent contraceptive use and rapid repeat pregnancy at 12 months postpartum in 200 opioid dependent (OD) women.
A significant minority of children (ages 5-12) display problematic sexual behavior and the persistence of this behavior is oftentimes as stable as other child behavior problems, such as aggression and defiance. Unfortunately, the only tested intervention protocols for these concerns utilize a group treatment modality that is not feasible in most community treatment settings. This project will define and pilot test an intervention for child sexual behavior problems that is applicable in most settings and can be easily disseminated as a first step toward validation in larger clinical trials.
Oral contraceptives (OCs) ameliorate hyperandrogenism and regulate menstrual cycles. To reduce androgenic side effects of first- and second-generation progestins, several new progestins derived from progesterone or spironolactone have been developed in the last few decades. These progestins, such as drospirenone, cyproterone acetate and NOMAC, are designed to bind specifically to the progesterone receptor and to have no androgenic, estrogenic or glucocorticoid actions. However, OCs with a more pronounced anti-androgenic effects are more likely to induce sexual dysfunction, mainly hypoactive sexual desire disorder, which can highly impact patient and partner's quality of life. Moreover, available data indicate that OC use might increase adiposity in adolescents and might be associated with central redistribution of body fat in young women with Polycystic ovary syndrome (PCOS) without a recognizable difference in clinical anthropometric measurements, including body mass index and waist circumference. In this context, it would be worth to evaluate the effects of combined OCs on metabolic and sexual health (sexual desire, arousal, and other parameters of sexual health), body image and mood.
India has the world's third largest HIV epidemic and men who have sex with men (MSM) are an identified high risk group. MSM in India face unique psychosocial stress underlying the context of HIV risk. To maximize the potential impact of an HIV prevention intervention, the purpose of this study is to test, in a two-arm randomized controlled efficacy trial, a behavioral intervention that addresses both psychosocial / contextual stress and reducing participant's risk for HIV.
This study evaluated the impact of the three-year Healthy Futures program on teen sexual behaviors in three Massachusetts cities.
