Non-Heterosexuality,Relationships, and Young Women’s Contraceptive Behavior

Non-heterosexual young women have a higher rate of unintended pregnancy than their heterosexual peers, but their fertility behaviors are understudied. We use longitudinal data from the Relationship Dynamics and Social Life study to investigate mechanisms contributing to non-heterosexual women’s higher pregnancy risk. These data include weekly reports of relationships, sex, and contraceptive use over 30 months. We compare the relationships and fertility behaviors of three groups: exclusively heterosexual (consistent heterosexual behavior, identity, and attraction); mostly heterosexual (heterosexual identity with same-sex behavior and/or same-sex attraction); and LGBTQ (any non-heterosexual identity). We find that mostly heterosexual and LGBTQ women behave differently from exclusively heterosexual women in ways likely to elevate their risk of unintended pregnancy: more distinct partners during the study period, more sexual intercourse with men, less frequent contraceptive use, less use of a dual method (condom plus hormonal method), and more gaps in contraceptive coverage. Mostly heterosexual women resemble LGBTQ women in their contraceptive behavior but have significantly more intercourse with men, which may increase their pregnancy risk relative to both LGBTQ and exclusively heterosexual women. We conclude by considering implications for LGBTQ health and the measurement of sexual minority populations.     

Exploring First Sexual Intercourse,Sexual Orientation,and Sexual Health in Men

In this study the characteristics of the sexual debut of men who have sex with men (MSM) and men who have sex with women (MSW) age 35 or younger (N = 1,201) were compared with one another. We investigated whether these characteristics were associated with sexual health and behavior, and to what extent. Compared to MSW, MSM tended to be older when they had their first sexual intercourse; their first sex partner was older, they felt less ready, and they experienced more pain. We also found that they reported a higher number of lifetime sexual partners and less condom use compared to MSW. Similarities were also ascertained, such as the fact that individuals from both groups do not differ significantly regarding how they experienced their first sexual intercourse emotionally. Many differences between these groups should not always be seen as problematic, whereas others still indicate a need for targeted interventions.     

The influence of psychological and situational factors on the contraceptive behavior of single men: A review of the literature

The study of contraceptive behavior has focused on women with relatively few studies examining the psychological and situational factors that influence male contraceptive behavior. A review of empirical studies indicates the importance of the personality variable of sexual anxiety and the cognitive variables of attitudes toward contraception and sex roles in influencing the contraceptive behavior of single males. However, the situational variable of having an established sexual relationship is the best predictor of whether contraception is used. Although the contributions of attitude and utility theorists have been of substantial assistance in understanding the contraceptive behavior of married couples, the affect-reinforcement theory appears to be more applicable to contraceptive behavior in general. An analysis of the socialization of males and females in terms of utility theory also helps explain the relative failure of adolescent couples in contraception.This research was funded by team grants from Health and Welfare, Family Planning Division, Canada and from Ministère des Affaires Sociales, Quebec.

Proximate determinants of Philippine fertility: 1983 levels and patterns

Data from the 1983 National Demographic Survey are used to analyze the proximate determinants of Philippine fertility in each of the 3 stages of family formation and to identify all of the direct and indirect factors affecting fertility levels and trends. 10,843 ever-married women and 12,771 children were included. The analysis pertains first to the starting patterns of family formation, the age at first birth, and the proximate determinants (age at menarche, age at first marriage/union, conception before first birth, fetal wastage first birth, interval between first marriage and first birth). Further analysis examines birth spacing patterns including the postpartum nonsusceptible period, the exposure interval and stopping patterns. Almost all births occur within marriage, and childbearing begins late at 22.5 years. However, 15.4% of first births are conceived premaritally. The mean age at first birth increases from younger to older cohorts. Urban women were slightly older (23.0 years) at the birth of their first child. Those with education below the 4th grade had first births 3.5 years earlier. Contraceptive use was low at 1.8% before first birth. Younger cohorts were more likely to use birth control and urban wives were more likely to use it than rural wives. 6.4% reported a first pregnancy ending in nonlive births, which were primarily spontaneous abortions (5.2%), stillbirths (1.0%), and induced abortions (.2%). 5.8% report never having been pregnant and 1.1% never having given birth to a live-born child. 20.4% were childless between the ages of 15-24 years, and 4.6% between 25-34 years. Childlessness was slightly higher among urban women (7.1%) than rural women (6.7%). A decreasing age at menarche has appeared; i.e., 13.6 years for the cohort 15-24 years, and 14.0 for the oldest cohort. By age 15, 82.9% had begun menstruating. The mean age at marriage is early at 20.7 years, and older cohorts tended to marry later at 21.4 years. Urban women marry a year later (21.4 years) than rural women. Lower educated women marry 4 years earlier. The mean length between first marriage and first birth was 18.4 months. In the younger cohorts, spacing patterns are shorter. Postpartum susceptibility is short. Return to sexual relations after a birth occurred at 2.8 months. The exposure time required to conceive is fairly long at 16.6 months and is attributed to contraceptive use, since coital frequency is high and temporary separation is infrequent. The average age at last birth is late at 37.6 years.     

Contraceptive acceptance and pregnancy: a matrix approach to the analysis of competing risks

Abstract This paper represents an initial attempt to formalize the relationships among post-partum sterility, fecundability, and contraceptive acceptance in terms of absorbing Markov chains. Acceptance of contraception offered by family planning programmes is analyzed as a possible event in time for a cohort of recently delivered women as they pass through phases of temporary sterility and fecundability towards another possible pregnancy. The results of the study indicate that once a woman leaves the post-partum anovulatory stage, the probability of her becoming pregnant again is large compared to the competing rates of contraceptive acceptance currently in force. Unless highly fecund non-contracepting women are approached by family planning programmes shortly after a pregnancy has been terminated (by childbirth or abortion), they will quickly become ineligible to accept either the pill or IUD because of once again being 'currently pregnant'.     

郑州市大学生性行为现状及影响因素

本文利用2006年3月在郑州市4所大学调查的326名大学生性观念和行为的调查数据,分析了郑州市目前大学生性行为现状及影响因素。结果表明,有45.6%的男大学生和40.6%的女大学生承认与异性有过接吻、抚摩等性接触经历;其中,有36%男性和16%的女性与异性有过性交经历。比较而言,女大学生比男大学生更喜欢非性交的性接触。影响大学生性行为的因素不仅在男女之间有很大的差异,在男性和女性内部也有很大的差异。对待性的态度(性观念)和家庭社会经济地位对大学生的性行为有很强的影响,其中,家庭社会经济地位低的和高的大学生比条件一般的大学生更容易与异性发生性行为。家教的严格程度、家庭关系的和谐程度,与家庭联系的频繁程度等对女大学生的性行为有强烈的影响,但对男大学生没有影响。抽烟对男大学生的性行为,有很强的影响,对女大学生的性行为则没有影响;而喝酒只影响男大学生的非性交性行为和女大学生的性交性行为。在未来可能实施的一些降低女大学生的高危行为的项目中,家庭的参与是非常重要的一个方面。     

Why women who don't want to get pregnant don't use contraception

In the developing world about 120 million women have an unmet need for contraception. They want to postpone childbearing, yet they do not use contraception, often because of the unavailability of services and supplies. However, according to a recent article by John Bongaarts, the primary factors are lack of knowledge about a contraceptive method, concern about side effects, and the disapproval of the male partner in developing countries. Lack of knowledge means inability to describe the uses of a contraceptive, its side effects, and the locale of its availability. An approximate knowledge index was calculated for such women, which showed that knowledge level positively correlated with contraceptive prevalence. Countries where the index was below 50% had a contraceptive prevalence of 8% only. The determinant reasons why women were reluctant to use the pill, IUD, and sterilization had to do with health and the fear of side effects, such as nausea and increased bleeding. The contraceptive prevalence among these women was reduced by 71% for the pill, 86% for the IUD, and 52% for sterilization. In Sub-Saharan countries nearly 70% of women cited partner disapproval of contraception, although they had never discussed family planning with their partners. The central concept for reducing unmet need is access with quality, which means that services are voluntary, safe, and appropriate in delivery. Some of the recommendations to reduce the unmet need for contraception include: one-on-one same-sex discussions to increase contraceptive knowledge and acceptability; sensitive responses by programs to their client's health concerns; support by service providers to women negotiating with male partners in order to mitigate male disapproval; and sex education and family planning services to reduce unwanted and early sexual contact and pregnancy while girls develop identities apart from mothering roles.     

Trends in reproductive behavior among young single women in Colombia and Peru: 1985–1999

Using "calendar" data for single women aged 15-24 from successive Demographic and Health Surveys (DHS) conducted in Colombia and Peru during the 1990s, we document trends, year by year, in sexual activity, the use of contraceptives, and subsequent reproductive outcomes. We provide evidence of the important and hitherto largely untapped potential of DHS calendar data to draw complete sexual and reproductive profiles when data from various surveys are integrated. Over the period 1985-1999, young single women in both Colombia and Peru became sexually active at younger ages. The use of contraceptives, especially the use of condoms, increased but did not fully offset the rise in sexual activity, and thus the incidence of premarital conceptions rose among young single women. In both countries, sharp declines occurred in the proportion of premaritally conceived births that were reported as being wanted.     

HIV testing,perceptions of AIDS risk,and condom use motivation among US women

As STD infections including HIV increase in the United States, it has become increasingly important to policy makers to ascertain the extent to which knowledge and perceptions of AIDS risk affect an individual's probability of altering their sexual or contraceptive behavior to avoid infection. This paper examines the extent to which women's perceptions of their own and their partners' risk of HIV infection affects the probability of using a condom for protection against sexually transmitted diseases. This paper also examines the extent to which HIV testing may affect motivation for condom use. Crosstabulations reveal that prophylactic condom use is more prevalent among women who have been tested for HIV and increase as perceptions of their chance (and their partner's chance) of being positive increases. The multivariate results from this study indicate that having an HIV test significantly predicts the likelihood of using a condom for STD prevention for US women. Furthermore, women who perceive themselves to be at least somewhat likely to be HIV positive have a higher probability of using a condom to prevent sexually transmitted disease, and women who perceive their partners to be HIV positive are twice as likely as other women to use a condom for STD prevention. However, women who consider themselves likely to be HIV positive are no more likely to use a condom than those who consider themselves not at risk.     

Does Contraceptive Use Always Reduce Breast-feeding?

Previous studies suggest that access to modern contraceptives can reduce breast-feeding rates because women who had been using breast-feeding to avoid pregnancy substitute away from it. This article shows that contraceptive use can also have a positive effect on breast-feeding. A mother often weans a child if she becomes pregnant again, which can occur sooner than desired if she lacks access to contraceptives. Thus, by enabling longer birth spacing and preventing unwanted pregnancies, contraceptive use allows for a longer duration of breast-feeding. This positive effect should primarily affect infants who are past the first few months of life because their mothers are more fecund then, and the negative effect should affect infants who are very young because the contraceptive property of breast-feeding is strongest then. I test for these dual effects using Demographic and Health Survey data for Indonesia. I find evidence of the positive birth-spacing effect: contraceptive use increases the likelihood that children continue to be breast-fed past age 1. There is also suggestive evidence of a negative substitution effect among infants age 3 months and younger.     

Sexual Preferences and Partnerships of Transgender Persons Mid- or Post-Transition

The process of gender transition has varying effects on various aspects of sexuality. The purpose of this study was to investigate the effects of transitioning on transgender persons’ sexual preferences and partnerships. Data were collected through an anonymous online survey. Questions focused on timing of gender transition in relation to change in sexual preference. Transgender individuals have a variety of sexual partners, predominantly cisgender, and may change sexual preference when they transition. Transitioning can be associated with having no primary sexual partner, despite past sexual partnerships. Length of time between identifying as transgender and starting the transition might be associated with changing sexual partner preference, particularly in transgender women. The emerging trends of sexual partnerships and changing sexual preferences related to the transition in this study warrant further investigation. These data provide more understanding of the relationship between transitioning and sexual preferences and partnerships.     

Norplant capsules perform better with soft tubing

Norplant is a contraceptive method which, when used, prevents women from becoming pregnant for 5 years. It has been approved in 60 countries, and at least 6 million women have used it. The Norplant implants function by releasing small amounts of levonorgestrel, a synthetic progestin, through 6 capsules implanted under the skin of a woman's upper arm. Results published in the September 1998 issue of Obstetrics & Gynecology of the first 5-year study of the soft-tubing Norplant contraceptive since its approval in the US in 1990 found that the implant's efficacy is comparable to that of being surgically sterilized. The prospective multicenter trial involving 511 female volunteers, who accumulated 1642 woman-years of method use, at clinics in California, New Jersey, and New York observed a pregnancy rate for the method of 3/1000/year. This rate is one-third of that stated on the Norplant product label. The scientific literature on Norplant understates the method's ability to prevent pregnancy because most of the data were collected based upon using hard-tubing implants. The soft-tubing version of the method was first distributed in the US in 1991, with the difference between the two tubings being the amount of silicate used to strengthen the capsule. More than 80% of women continued using the method from year to year over the 5-year period, for a median of 47 months. The soft-tubing Norplant system is highly effective in women of all weights, even among those in their later reproductive years.     

Rural-to-Urban Migration and Sexual Debut in Thailand

Migration from one’s parents’ home and sexual debut are common features of the transition to adulthood. Although many studies have described both of these features independently, few have examined the relationship between migration and sexual debut in a systematic manner. In this study, we explore this link for young adults in Thailand. With relatively high rates of internal migration, rapid modernization, a moderate HIV epidemic, and a declining average age of sexual debut, Thailand presents an instructive environment in which to examine migration and sexual debut. We use two waves of a longitudinal data set (2005 and 2007) that includes a subsample of young adults who migrated to urban areas during that period. We identify characteristics and behaviors associated with sexual debut and examine the role of migration on debut. Our approach reduces several common sources of bias that hamper existing work on both migration and sexual debut: (1) the longitudinal nature of the data enables us to examine the effects of characteristics that predate both behaviors of interest; (2) the survey on sexual behavior employed a technique that reduces response bias; and (3) we examine differences in debut by marital status. We find that migrants have a higher likelihood of sexual debut than nonmigrants.     

Abortion in amsterdam

Abstract Mortality from abortion is low in the Netherlands to-day, and approximately equal to mortality at delivery. Calculations suggest that about 4,000 abortions occur in Amsterdam every year, of which about 2,100 are induced. The abortion rate shows a very gradual decline after the Second World War. An investigation of the social background of women with induced abortion showed no relationship between occupational group and the incidence of abortion, but a strong negative correlation between religion and abortion. Abortion was more common among women with disturbed relationships in their own or parental families. Induced abortion usually occurred in pregnancies resulting from failure of contraception; these failures were caused not by lack of knowledge of good contraceptives, but by ineffective practice of contraception. The inability to use contraceptive methods in an effective way is related to a lack of communication between the two partners, and to a negative attitude of the women towards sex. An attempt has been made to formulate a theory of the causes of induced abortion among the women interviewed in Amsterdam.     

A meta-analysis of research on adolescent contraceptive use

Meta-analysis was used to summarize the results of 134 studies of adolescent contraceptive use in relation to two major explanatory models, the career model and the decision model. There was evidence in support of both models, although there has been less research conducted on variables related to the decision model. The major variables found to affect young women's contraceptive use were partner influence to use contraception, acceptance of one's sexuality, future orientation, positive attitudes toward contraception, an exclusive sexual relationship, and frequency of intercourse. The major variables affecting young men's contraceptive use were partner influence, frequency of intercourse, and positive attitudes toward contraception; however, there was relatively little research on young men compared to young women. A number of possible future directions for research are noted.We would like to thank Nancy Adler and Catherine Chilman for their comments on an earlier version of this article.

Sexuality in Older Spanish Women: Voices and Reflections

Our research has been aimed at understanding the experience, practice, and sexual life in a group of Spanish women over 50 years of age. We studied a sample of 729 women between 50 and 80 years old. Our results provide qualitative and quantitative information and important insights about the sexual life of Spanish women and identify differences in the experience and reality of sexual life after the age of 70. The status of having or lacking a partner, and a personal interest in emotional relationships and sexual practices, are elements that determine the possibility of enjoying a satisfying postmenopausal sexuality.     

Partner involvement and contraceptive efficacy in premarital sexual relationships

This paper attempts to account for the strong, positive correlation between partner involvement and contraceptive behavior in premarital sexual relationships. Interpersonal and structural characteristics of partner involvement identified in previous research as possible explanatory variables were factor analyzed and three major dimensions were isolated: 1. affection and commitment, 2. sexual and contraceptive communication, and 3. predictability of intercourse. Partner involvement loaded highest on the affect factor. In a multiple regression analysis using composite (factor) scores, prior sex-related communication emerged as the strongest predictor of contraceptive behavior, followed by affection for partner; contrary to expectations, however, predictability of intercourse was not significantly related to contraceptive use.Funded by a grant from the Indiana University-Purdue University at Fort Wayne Research and Instructional Development Support Program.A version of this paper was presented at the Midwestern Psychological Association convention, Chicago, Illinois, May 3–5, 1984.Address requests for reprints to Judith K.
