Filter by:The purpose of this study is to determine how long it takes couples of normal fertility to get pregnant once they begin to try, and whether instruction in fertility awareness can decrease time to pregnancy in these couples.
This study will develop and evaluate a school-based HIV, STD, and pregnancy prevention program for 7th and 8th grade middle school students.
This is a randomized clinical trial assessing the efficacy of two types of counseling (Computer-Assisted Motivational Intervention [CAMI] versus Didactic Educational Counseling [DEC]) to see which can better reduce female adolescents' risk taking behaviors that put them at risk for unintended pregnancy and sexually transmitted diseases (STDs). The intervention phase consists of three 30-minute counseling sessions over the first 6 months followed by a visit every three months during the 12 month follow up phase. We, the researchers, hypothesize that the CAMI will decrease the proportion of subjects who engage in any intercourse that is poorly protected against pregnancy and against STDs.
This study is designed to test the hypothesis that the level of the thyroid hormone thyroxine (specifically, free thyroxine, FT4) circulating in the blood of pregnant women is the key thyroid-related factor to influence early fetal brain development. The investigators will recruit 5000 pregnant women with clinically normal thyroid function (normal thyroid stimulating hormone levels) in the second trimester. After the baby has been born, the investigators will measure FT4 in the second trimester maternal blood sample to identify 100 cases (very low FT4 levels) and 100 matched controls (normal FT4 levels). The children of cases and controls will undergo neurodevelopmental testing at 2 years of age to determine whether IQ differs according to maternal FT4 levels during pregnancy. The potential impact of the study is that if such an effect is found, it might be possible to avoid these adverse developmental consequences in children by designing and testing strategies to identify and treat high risk women.
Consistent and correct use of an effective contraceptive method is a primary determinant in preventing pregnancy. Unfortunately, only a minority of healthcare providers adequately address women’s contraceptive needs. We have developed a standardized behavioral-based contraceptive counseling model that can be used by providers and other clinic staff to address this limitation. The model, ESP, is an adaptation of motivational interviewing and involves: Exploring discrepancies between pregnancy intention and contraceptive use and between risk of STDs and condom use; Sharing information; and Promoting behaviors to reduce risk. Study question: Does ESP counseling lead to an increase in consistency and effectiveness of contraceptive use among women at risk of unintended pregnancy? Methods: Randomized controlled trial of 747 women, ages 16-44, at self-identified risk of unintended pregnancy enrolled from March 2003 to September 2004 at healthcare settings in North Carolina. Intervention participants received individualized ESP counseling from a health educator to address barriers to effective and consistent contraceptive use. Risk reduction steps were negotiated. Pregnancy, Chlamydia infection and contraceptive use were assessed at baseline and follow-up. “Highly effective” contraceptive use was defined as a combination of effectiveness and consistency. Women in the control arm received general preventive health counseling (e.g., smoking and exercise). Differences between the study arms at 12-months may illustrate the longer term influence of the intervention.
Parents Matter is a community-based project whose goal it is to develop and test an intervention designed to promote effective parent-child communication about sexuality in order to promote sexual health among adolescents.
Malaria in pregnancy is potentially fatal to both the mother and the foetus particularly in the primigravidae. Implementation of appropriate control and preventive measures is challenged by the fact that malaria infection in pregnancy is often asymptomatic and parasitized red blood cells sequestrated in the placental microcirculation may not be detectable in the peripheral blood. In addition, the widespread prevalence of parasites resistant to chloroquine and sulphadoxine-pyrimethamine (SP) and, the safety concerns about newer antimalarials, poverty and inadequate supply have made antimalarial treatment options available to pregnant women very limited. These have necessitated an urgent search for alternative safe and efficacious treatment options for pregnant women. The objective of this study is to assess the efficacy, safety and tolerability of four antimalarial treatment options in rural Ghana within a programme setting.
The purpose of this study is to examine whether treatment of pregnant Malawian women with repeated doses of sulfadoxine-pyrimethamine and azithromycin antibiotics will prevent preterm deliveries and result in other health benefits both for the mother and the foetus/newborn.
The purpose of this study was to compare labor outcomes in women accompanied by an additional support person (doula group) with outcomes in women who did not have this additional support person (control group). The current study was designed with the benefits of continuous labor support in mind as well as the need for a cost-effective, affordable program to provide those services for low-income women. Its purpose was to evaluate the effects of continuous labor support provided by a female companion of the pregnant person's choosing who, with the mother, had participated in an educational program to teach her how to provide continuous labor support.
The purpose of this study is to examine the drug interactions between a protease inhibitor (PI)-based regimen including lopinavir/ritonavir (LPV/r) and two forms of contraceptive medications in HIV infected women.
