Contraceptive practice and trends in coital frequency.

Coital frequency among white, continuously married couples increased by 19 percent between 1965 and 1970, but by only five percent between 1970 and 1975. All of the increase in the latter five-year period is connected with a greater concentration of women in pregnancy-exposure and contraceptive-use categories associated with higher coital frequency. Over the five years, individual women who switched to more effective methods did not, on the average, experience as much of a decline in coital frequency as those who changed to less effective methods and those who did not change methods. (Some decline would be expected to be associated with the five-year increase in age.)

It's all in the timing: coital frequency and fertility awareness-based methods of family planning.

Fertility awareness-based methods of family planning help women to identify the days of the cycle they should avoid unprotected intercourse to prevent pregnancy. Therefore using fertility awareness-based methods influences the timing of sexual activity, which may affect the nature of the sexual relationship. Data are used from the clinical trials of two fertility awareness-based methods--the Standard Days Method and the TwoDay Method--to determine the frequency and timing of intercourse during the cycle, and the determinants of coital frequency. The mean coital frequency of study participants was similar to that reported by users of other methods. Results suggest that coital frequency increases with consecutive cycles of method use. At the same time the frequency of intercourse during the identified fertile days and during menses decreases. This evidence implies a behavioural change as couples get more experience using their method and communicating about the fertile days. Coital frequency was also influenced by the method used and by the study sites. Potential differences between the methods and sites that may contribute to this effect are discussed.

Determinants of coital frequency among married women in Central African Republic: the role of female genital cutting.

This paper examines determinants of one aspect of sexual behaviour--coital frequency--among 2,188 married women in the Central African Republic using a secondary analysis of data from the Demographic and Health Survey of 1994-95. Female genital cutting (or circumcision) is practised in the Central African Republic and self-reported circumcision status was included in the questionnaire enabling it to be examined as a possible determinant of coital frequency. Multiple logistic regression was used to find a subset of factors independently associated with coital frequency. Decreased coital frequency was found in those who had longer duration of marriage, those who were not the most recent wife in a polygamous marriage and those who had more surviving children. Coital frequency was higher in more educated women and those not contracepting because they wanted to get pregnant. After adjusting for confounders no association between female genital cutting and coital frequency was found. The extent to which women can control coital frequency in this culture is not known and fertility desires may override any negative effects of circumcision on sexual pleasure. It was therefore not possible to draw conclusions about how female genital cutting affects a woman's desire for sexual intercourse and consequently there is a need to develop research methods further to investigate this question.

Coital frequency among married and cohabiting couples in the United States.

Coital frequency is studied among couples as a function of marital or cohabiting status, relationship duration, number of children, religious affiliation, income, education, fertility intentions, age, race, self-assessed health, time spent in work, and perceived relationship quality. Data are from the 1987-88 National Survey of Families and Households. Predictors of coital frequency that were stable across several analyses were male's and female's ages, the duration of the relationship, and the male partner's self-assessed health. When the discrepancy in partners' reports was adjusted, cohabitation status, number of children, future fertility intentions, religious affiliation, and relationship quality as assessed by the female partner were significant. The results suggest a substantial idiosyncratic component to the determination of coital frequency in relationships.

Retrospective vs. prospective coital frequency and menstrual cycle length in a contraceptive effectiveness trial.

PURPOSE: To determine how well information at enrollment would predict coital frequency and menstrual segment length during a prospective contraceptive effectiveness trial. METHODS: We compared retrospective reports of monthly coital frequency and menstrual segment (cycle) length with prospective information for women participating in a contraceptive trial of the Reality((R)) female condom. RESULTS: Participants reported slightly higher mean monthly coital frequency and slightly longer menstrual segments prior to the study than during the study (12.6 acts vs. 12.0 acts per month and 30.8 days vs. 28.4 days). We examined the actual distribution of differences between the retrospective and prospective measures and found considerable variability. Among the 195 participants studied, parous women were less likely to predict accurately menstrual segment length (OR 0.4; 95% CI 0.3--0.9), while older women were more likely to predict accurately coital frequency (OR 1.9; 95% CI 0.9--3.3). CONCLUSIONS: Coital frequency and menstrual segment length vary considerably over time. Hence, prospective data collection is essential to accurately characterize these variations and to properly interpret results from contraceptive trials and other studies concerned with fecundability and hazards of reproduction.

Relationship quality, coital frequency, and condom use as predictors of incident genital Chlamydia trachomatis infection among adolescent women.

PURPOSE: To explore associations of relationship quality, coital frequency, unprotected coitus, and chlamydia infection over time. METHODS: Data came from 142 adolescent females with sexually transmitted infections attending three primary care adolescent clinics and one county STD clinic. Interview data were collected at 3 time points: enrollment, 1 month, and 3 months after enrollment. Predictor variables included relationship quality, coital frequency, unprotected coitus, and partner change. The outcome variable was infection with C. trachomatis at 3 months. Analyses were conducted using structural equation modeling. RESULTS: Chlamydia infection at 3 months was directly influenced by unprotected coitus during the previous 2 months (Beta = .25; p < or = .05) and partner change during the enrollment/1-month interval. Unprotected coitus was directly associated with coital frequency, both cross-sectionally and longitudinally. Increased relationship quality was associated with increased coital frequency but did not have direct effects on unprotected coitus. CONCLUSIONS: The data showed a protective effect of condom use for chlamydia infections. Prevention efforts should attend to the interpersonal factors behind decisions to use or not use condoms.

Irregular bleeding, body mass index and coital frequency in Norplant contraceptive users.

Seventy-five women with a mean age of 27.5 years who requested Norplant implants for contraception were studied over a five-year period. The patients kept daily diaries of their vaginal bleeding and coital frequency, and were seen at least every six months at which time their weight was measured. This study examines the impact of Norplant implants use on menstrual regularity, body mass index and coital frequency. Irregular bleeding was most prevalent during the first two years of Norplant implants use and accounted for the primary reason for discontinuation of this method. No increase in Body Mass Index (BMI) was noted in Norplant implants users over the five-year study period. Women with irregular bleeding did not have a higher or lower BMI compared to women with regular bleeding and irregular bleeding patterns did not impact on coital frequency. Over five years, four pregnancies occurred during Norplant implant use. Norplant implants are a highly effective contraceptive method and women using this method should not expect an increase in body weight. Irregular bleeding is most frequent during the first two years of use and menstrual cyclicity resumes in the majority of women by the third year of use and continues to the fifth year of use.

Abortions in relation to age, coital frequency, and fecundity.

Abortion rates show variations by age in the United States. This article addresses the question of age variations in abortions. Since the probability of pregnancy is increased in direct proportion to increased coital frequency, age and coitus-specific abortion rates are calculated. Since the probability of pregnancy is related to fecundity, age and fecundity abortion rates are also calculated. When combining coital frequency and fecundity with the age-specific abortion rates, the variation by age disappears for all women except teen-agers.

Coital frequency and twinning.

In a comparative study to enquire whether parents of twins, especially of dizygotic twins, have a higher frequency of sexual intercourse than parents of singleton infants, data on sociodemographic status, coital frequency and other variables were collected using a postal questionnaire. Parents of all twins born alive in Denmark in 1984 or 1985 were included as cases and a random sample of parents of singleton infants born in the same period were controls. No evidence of any difference in coital frequency was found between parents of twins (neither dizygotic twins nor monozygotic) and parents of singleton infants.

Supravaginal uterine amputation vs. hysterectomy. Effects on coital frequency and dyspareunia.

The author has personally interviewed and examined 105 abdominal hysterectomy patients and 107 supravaginal amputation patients, first preoperatively and then 6 weeks, 6 months and one year postoperatively. At 12 months the follow-up percentage was 99.5 (211/212). This report concentrates on coital frequency and dyspareunia. In the statistical analysis, McNewar's test of symmetry and the Fisher exact test were used. With respect to coital frequency, no statistically significant changes occurred between or within the two groups. Dyspareunia was relieved by either operation, but more so by supravaginal amputation. When dyspareunia was experienced deep within the pelvis, removal of the uterus by either method almost always resulted in disappearance of the symptom.

Influence of cycle variability and coital frequency on the risk of pregnancy.

Researchers have cautioned against generalizing results from contraceptive trials because these studies rely on self-selected participants meeting strict selection criteria who may differ from typical users. Using information collected on daily diaries, we reanalyzed data from the recently completed Reality female condom clinical trial to evaluate factors that influence the probability of pregnancy. Noncompliant women, women with less variable menstrual cycles (17-43 days), and women engaging in intercourse frequently (> or = 11 acts per month) were more likely to conceive during this 6-month trial. The adjusted hazard ratios and 95% confidence intervals for these three covariates were 6.1 (2.0-18.7), 7.2 (1.0-54.3), and 2.0 (0.7-5.3), respectively. The strict selection criteria used in this study failed to recruit a homogeneous cohort with respect to factors that influence the risk of pregnancy. The overall pregnancy rate does not pertain to individual study participants, but rather represent average effects for a population with the particular mix of characteristics found in this study. In particular, we not only confirm the well known importance of compliance and the obvious role of frequency of intercourse, but also demonstrate that women with cycles outside the range of 17-43 days appear to be at a much lower risk of pregnancy.

Distribution of time of first birth in presence of social customs regulating physical separation and coital frequency.

The interval between marriage and the first birth in India, particularly in rural areas, is much longer than what is observed in western countries. In eastern Uttar Pradesh, the mean interval is observed to be even longer, possibly due to traditional customs such as the female partner's visits to her parents in the early years of marriage and the smaller chance of coition because of the observance of rigid intercourse taboos. Thus the models to explain the length of the interval of marriage to first birth proposed by Western demographers, which assume that the period of cohabitation between marriage and first birth is uninterrupted, often do not describe the data satisfactorily when applied to rural India. In this paper a model to describe data on first birth interval is proposed that takes account of the distributions of timing and periods of physical separation and variation in fecundity with effective marriage duration.

Cognitive and hormonal factors accecting coital frequency.

Sexual behavior of female undergraduates was assessed by daily questionnaries. Of the 24 subjects, 13 were taking oral contraceptives ("pill" subjects) and 11 were using other methods of birth control ("nonpill" subjects), primarily diaphragm or male prophylactic methods. Three main results were obtained: (1) Intercourse rates were lowest during menstruation and highest immediately following menstruation. (2) Self-rated sexual arousal on a given day correlated with the type of heterosexual encouters on that day rather than with period of the menstrual cycle. (3) Pill subjects reported intercourse on more days than nonpill subjects but reported a lower number of intercourse sessions on day with intercourse than nonpill subjects. These results are interpreted within a general framework of sexual behavior which recognizes the sexual behavior of humans as primarily influenced by cultural and cognitive factors. The possibility is discussed that female sexual behavior might also be found to be affected by hormones if more sensitive measures were used.
