The purpose of this study was to investigate Black South African freshmen's experience of first intercourse and contraception. The study found that many students do not use contraception during first intercourse and that peers were reported as the primary first source of learning about sexual intercourse as well as the preferred source. Freshmen who are contemplating, anticipating or deferring the transition from virginity to non-virginity are an important target group for campus safer sex programmes because safer sex behaviours could be encouraged before a high risk sexual behavior pattern develops. 相似文献

Despite awareness of the growing number of pregnant teens in the US, little information has been published concerning factors that predict early childbirth among individual girls. To begin to address this issue, the influence of specific life and social factors was examined in 50 adolescent girls with documented histories of good and poor contraception use. Patients selected for participation were 50 indigent nulliparous adolescent and young adult females from 14-22 years old receiving health care at the Teen Health Clinic at the Jefferson Davis Hospital in Houston, Texas. 25 adolescents who indicated that they had been able to use oral contraception prescribed by the clinic for at least 6 months without major problems or complaints were classified as good contraceptors. 25 adolescents assigned to the poor contraceptors group were those who missed 2 or more appointments in a 6-month interval, experienced at least one suspected pregnancy during this time, and indicated verbally that they had not been completely compliant. Each subject was assessed with a structured interview consisting of 25 questions on the patient's past history of contraception, school performance, family birth, employment, residence patterns, and accessibility to contraceptive services. Data from each of the 25 questions of the interview were pooled for the good and poor contraceptors. Where applicable, Chi-square frequency tests and t-tests were used to determine whether differences were statistically significant. Some of the results follow. 1) Reasons for occasional nonuse of oral contraception in the 12 months prior to the interview were assessed in both samples; no statistical differences were observed. The majority of nonusers attributed it to a random event, such as a memory lapse. 2) Sources of birth control education were equivalent in the 2 groups. 3) Good contraceptors reported intercourse 2.6 times/month, as compared to 4.7 times/month for poor contraceptors. 4) 3 of 25 good contraceptors had dropped out of school, while 9 out of 25 poor contraceptors had left school. 5) 72% of the good contraceptors intended to complete at least 2 years of college, but only 52% of the poor contraceptors did. 6) Poor contraceptors had a greater frequency of sisters who had become pregnant relative to good contraceptors. 7) Good contraceptors were more likely to be employed either part- or full-time (52%) than were the poor contraceptors (28%). 8) Good contraceptors reported fewer changes in residence relative to the poor contraceptors in the preceding 5 years. 9) Poor contraceptors had significantly longer travel times to the clinic (mean of 54.5 minutes) relative to good contraceptors (mean of 33 minutes). 相似文献

Abstract This article reports on the conduct and results of a randomised controlled trial to test the effectiveness of a teacher‐led intervention to improve teenagers' knowledge of emergency contraception. The trial was successfully conducted in 24 mixed‐sex state secondary schools in Avon, South‐west England. The intervention was popular with both teachers and pupils, and significantly improved pupils' knowledge of emergency contraception. The article uses the emergency contraception trial to demonstrate the feasibility of conducting large‐scale randomised trials in schools. The article focuses particularly on study design, specification of research question, recruitment of schools and method of randomisation to highlight methodological choices that can maximise the feasibility and value of such trials to answer questions regarding the effectiveness of complex educational interventions. The article also highlights the importance of using theory and mixed research methods both to thoroughly develop an intervention before it is tested in a trial, and also to evaluate factors affecting its success within a trial. 相似文献

The aim of this study was to examine both positive and negative aspects of relationship quality in relation to condom use. Sexually active young women aged 14–18 years (n = 111; 34% non-white) were recruited from community clinics and schools in the Midwest USA and provided data via an online survey. The number of unprotected sex acts in the past month with the most recent male partner was regressed on relationship quality with that partner, adjusting for demographics and other characteristics. Negative relationship quality was associated with a greater number of unprotected sex acts among women reporting a low level of positive relationship quality and among women taking hormonal/IUD contraception. Positive relationship quality was associated with unprotected sex among women who reported multiple partners in the past month. Both positive and negative aspects of relationship quality may confer risk for unprotected sex. This risk appears to be modified by patterns of contraceptive use and other sexual behaviours. Health professionals and sexual health educators may be more effective in promoting condom use if they ask questions about both positive and negative aspects of young people’s relationship quality and tailor their conversations based on the responses received. 相似文献

This study demonstrates a method for obtaining data on developmental changes in adolescents' interest in human sexuality. A content analysis was done on a sample of 874 student-generated questions. Question boxes were placed in classrooms so students could anonymously submit questions. In deference to perceived community pressure, questions on abortion, homosexuality, and masturbation were not allowed. Students who wrote the questions are 7th, 8th, and 10th graders enrolled in 13 different public schools. The schools are located in several small communities and on an American Indian reservation in a rural area of northern California. All children who participated did so voluntarily and with parental permission. Of the total 874 questions. 7th and 8th graders provided 593, while sophomores accounted for 233. Gender information was available only for 7th and 8th graders. Boys asked 173 questions while girls asked 241. The data are broken down by gender and by grade (7th and 8th vs. 10th). Findings reveal that younger students show more interest in the meaning of slang terms, their reproductive physiology, and intercourse. Older students show greater interest in contraception and health risks. Males are interested in slang and intercourse while females are more concerned with health risks and communication. One unexpected finding indicates that among younger children, boys and girls are equally interested in birth control and pregnancy; in the lower grades then, may be the prime time to use sex education programs to strengthen the sense of dual responsibility for knowledge about contraception and pregnancy. Also, the relative absence of questions on disallowed issues (2.5%) makes it apparent that sex educators can effectively suppress inquiry into topics that are of great interest to youngsters; only about 1/3 of the students indicated that their parents had discussed these disllowed issues, yet 48% of the students expressed interest in knowing more about abortion. 相似文献

The purpose of this study was to identify the factors that influence undergraduate college student use of emergency contraception (EC) and their level of knowledge about the product, in order to assist in the development of intervention programmes to increase its use, which could lead to lower rates of unintended pregnancies in this population. A response rate of 98.4% included 1553 surveys from students at 11 Midwestern universities. Students were predominantly female (63.5%), white (75.3%) and aged 18–21 years (80%). They ranged from first-year students (23.8%) through to fourth-year students (13.8%), with second-year students comprising the largest group (32.6%). The majority of respondents reported being heterosexual (92.1%), and 34.1% of those completing the questionnaire reported being in a committed relationship. Most respondents reported having had sexual intercourse at least once in their lifetime (78.9%). Of the 8.4% of sexually active students who had experienced an unintended pregnancy, 18.1% had used EC in the past 12 months. Knowledge of EC was not high; but as knowledge increased, the use of EC increased. The Integrated Behavioural Model predicted 50% of the variance in intention. Each construct contributed a portion of variance except experiential attitude, which was not statistically significant in the path analysis. The model could be used in any future interventions to increase EC use and decrease unintended pregnancies among college students. 相似文献

8% of all individuals residing in the US have tested positive for infection with HIV. This study reports the use of condoms and others forms of contraception in two samples of students from East Carolina University. 234 students in 1982 taking a course in marriage and family responded to a 32-item questionnaire distributed in five classes on whether they had used contraception during their most recent episode of sexual intercourse and which method they used. 96% of the respondents were never married, 83% white, and 82% middle class. 7% were engaged to be married and 3% were cohabiting. 53.4% were women and in their junior or senior year (52.5%) of undergraduate education. While the sample was not random, it closely approximated the demographic characteristics of the university from which it was drawn. 79.1% reported using some form of contraception, with 61.8% using the pill and 15.3% using the condom. Of those who used a form of contraception, 8.1% reported using withdrawal and 1.5% rhythm. Fifty university students were again sampled in 1992 in a marriage and family class to find 76% reporting use of contraception during their last episode of sexual intercourse. The percentage of students which reported using a condom, however, increased to 39%. These findings add to the body of research literature which suggests that condom use has increased over the past decade. Further research is, however, warranted to determine whether these data reflect an actual increase in condom use or are simply the result of students providing socially desirable answers. 相似文献
