Epidemiology and determinants of induced abortion in the U.S.S.R.

Since the mid-50s, induced abortion (IA) has been the principal method of birth control for as much as 80% of the U.S.S.R. population, with more than 9 million of terminations performed annually. After brief discussion of the general and specific reasons for a long-term IA dominance in family planning practices, data of the national statistics and local surveys on IA prevalence, contraceptive use and their determinants are critically reviewed. Although most couples are willing to use contraception, they have to rely on traditional methods with high failure rates (withdrawal, condom, rhythm/calendar). Due to many years of misleading information, population views on pros and cons of various birth control methods are severely biased. Public health implications of multiple IA are summarised.

Experience with the Small-Carrion penile prosthesis.

The Small-Carrion prosthesis has been implanted successfully in 14 of 15 patients. These prostheses are implanted through a dorsal midline penile incision which simplifies the procedure. The perineal approach is preferred for keloid formers and paraplegics who will use a condom catheter. Operative failure may be decreased by paying particular attention to the size of prosthesis implanted and the positioning of its distal tip.

[Risk behaviors for HIV transmission among the recent clients of a syringe-exchange program in Madrid, 1993].

OBJECTIVE: To determine the prevalence of the major risk behavior in HIV transmission (syringe sharing and failure to use condoms) and associated factors among drug injectors recruited for a syringe exchange program (PIJ) in the city of Madrid. METHODS: Cross-section study. All the information was obtained in 1993 through structured interviews with 441 users who had injected drugs during the previous month and had resorted to the PIJ five times, at most. The reference period for drug use and risk behaviour was the month prior to the interview. The statistical analysis included bivariate methods and logistical regression techniques. RESULTS: 29.2% shared syringes (18% passing and 21.7% taking used syringes) and of those that had sexual intercourse (49.4%), 42.5% always used a condom. 89.5% had an HIV antibody test and of those that knew the results, 48.6% were HIV-positive. Multivariate analysis showed that the association between certain behaviour patterns was significant; i.e., taking used syringes and: passing used syringes (odds ratio -OR- = 6.1; 95% confidence interval -CI- = 3.0-12.5), being HIV-positive (OR = 4.1; CI = 1.8-9.1), being unaware of HIV antibody test status (OR = 4.2; CI = 1.7-10.2) and having used intravenous drugs for 5-9 years (OR = 2.9; CI = 1.1-7.9); the association was significant between passing used syringes and: using a mixture of heroin and cocaine (OR = 2.7; CI = 1.1-6.4) and being unaware of HIV antibody test status (OR = 2.5; CI = 1.1-6.0). In the sample as a whole, the association between not using condoms ever and consuming cocaine (OR = 1.7; CI = 1.1-2.9) or crack (OR = 3.0; CI = 1.5-5.9) was significant; furthermore, among those that had sexual intercourse, the association was significant between not using condoms ever and: having been in jail (OR = 2.9; CI = 1.3-6.4), injecting drugs 2-4 times a day (OR = 2.4; CI = 1.0-5.8), having sexual intercourse with drug injectors (OR = 2.6; CI = 1.2-5.9) and having intercourse with two or more partners (OR = 0.4; CI = 0.2-0.9). CONCLUSIONS: The prevalence of HIV infection and risk behavior in the transmission of this virus remain high among drug injectors in Madrid. The habit of sharing syringes is still common, especially among HIV-positive drug injectors (a high percentage take used syringe) and among those who are unaware of their HIV antibody test status. The use of condoms is less frequent among those who have sexual intercourse with other drug injectors or with only one partner.

Sexual risk behaviour among the youth in the era of HIV/AIDS in South Africa.

The paper discusses factors associated with sexual risk behaviour, i.e. failure to use condoms consistently during sexual intercourse, among unmarried sexually experienced youths in South Africa. Data from the 'Transitions to Adulthood in the Context of AIDS in South Africa' surveys of 1999 and 2001 were analysed to identify factors associated with high sexual risk behaviour among the youth. The multinomial regression models for male and female youths were fitted separately for the 1999 and 2001 data sets. The results show increasingly consistent use of condoms during sexual intercourse and that high sexual risk behaviour among youths is predominantly determined by social factors such as 'ever-pregnant' or 'ever made pregnant', 'ever given something for sex', age of sexual partner, currently in school, pressured by friends to have sex, peer influence on safe sex and education level for males. There is evidence that availability of contraception information is important in strategic interventions that seek to change the sexual behaviour of the youth in South Africa.

Sexual behaviour, STDs and risks for prostate cancer.

A population-based case-control study was carried out among 981 men (479 black, 502 white) with pathologically confirmed prostate cancer and 1315 controls (594 black, 721 white). In-person interviews elicited information on sexual behaviour and other potential risk factors for prostate cancer. Blood was drawn for serologic studies in a subset of the cases (n = 276) and controls (n = 295). Prostate cancer risk was increased among men who reported a history of gonorrhoea or syphilis (odds ratio (OR) = 1.6; 95% confidence internal (CI) 1.2-2.1) or showed serological evidence of syphilis (MHA-TP) (OR = 1.8; 95% CI 1.0-3.5). Patterns of risk for gonorrhoea and syphilis were similar for blacks (OR = 1.7; 95% CI 1.2-2.2) and whites (OR = 1.6; 95% CI 0.8-3.2). Risks increased with increasing occurrences of gonorrhoea, rising to OR = 3.3 (95% CI 1.4-7.8) among subjects with three or more events (Ptrend = 0.0005). Frequent sexual encounters with prostitutes and failure to use condoms were also associated with increased risk. Syphilis, gonorrhoea, sex with prostitutes and unprotected sexual intercourse may be indicators of contact with a sexually transmissible factor that increases the risk of prostate cancer.

High prevalence of asymptomatic STDs in incarcerated minority male youth: a case for screening.

BACKGROUND AND OBJECTIVES: To assess STD prevalence among a sample of incarcerated minority male youth in a southern US city. METHODS: A consecutive entrant, cross-sectional study of 284 minority males 14 to 18 years was performed. All adolescents were screened for gonorrhea and chlamydia using ligase chain reaction tests. RESULTS: Eighteen percent of youth were identified as having either gonorrhea, chlamydia, or both. Approximately 84% of those with sexually transmitted diseases (STDs) self-reported having no symptoms. Failure to use condoms in the past month was significantly associated with a positive test result for STDs (odds ratio = 1.9, 95% CI = 1.1-3.3). CONCLUSIONS: The findings indicate an urgent need for routine STD screening and STD-prevention programs for adolescent males in detention facilities. A study of 284 detained black male adolescents revealed 18% prevalence of gonorrhea, chlamydia, or both. Approximately 84% of those with sexually transmitted diseases self-reported not having symptoms.

Prevalence of Chlamydia trachomatis in asymptomatic Brazilian military conscripts.

BACKGROUND: Few data are available on the prevalence and risk factors for Chlamydia trachomatis infection among young men in Brazil. OBJECTIVES: To assess prevalence and risk factors for C. trachomatis infection in male military conscripts. METHODS: In 2000, 627 young men recruited for military service in Goiania, Goias, Brazil, were enrolled in this cross-sectional study. Participants completed a demographic and sexual risk behavior questionnaire, and urine samples were screened for C. trachomatis by polymerase chain reaction. RESULTS: The prevalence of chlamydial infection among asymptomatic conscripts was 5.0% (95% confidence interval [CI], 3.3-7.3). In multivariate analysis, failure to use condoms (odds ratio [OR](adjusted) 5.3; 95% confidence interval [CI], 1.2-23.4; P = 0.028) and having more than 2 sexual partners in the last 2 months (OR(adjusted) 2.6; 95% CI, 1.1-6.9; P = 0.049) were significantly associated with positivity for C. trachomatis. CONCLUSIONS: A substantial number of asymptomatic young male military recruits were infected with C. trachomatis, and risk factors for this infection were related to sexual behavior. Further research is required to determine if routine screening may be considered as a strategy to reduce prevalence among this population.

The Timing of Entry Into Fatherhood in Young, At-Risk Men.

Timing of first fatherhood was examined in a sample of 206 at-risk, predominantly White men, followed prospectively for 17 years. An event history analysis was used to test a model wherein antisocial behavior, the contextual and familial factors that may contribute to the development of antisocial behavior, and common correlates of such behavior, including academic failure, substance use, and early initiation of sexual behaviors, lead both directly and indirectly to an early transition to fatherhood. Having a mother who was younger at first birth, low family SES, poor academic skills, failure to use condoms, and being in a cohabitating or marital relationship predicted entry into fatherhood. Implications of the findings for prevention of and intervention with early fathering are discussed.

Psychosocial considerations for the prevention of HIV infection in injecting drug users.

In this article, the authors discuss a study that investigated the meaning that injecting drug users attribute to risk behaviors linked to HIV transmission, especially through the use of nonsterile syringes or the failure to use condoms. To do this, social discourses with respect to the prevention of HIV infection are evaluated. The discussion focuses on how these discourses affect the daily practices of heroin users, practices that in turn influence discourses. Ethnography was used to observe 78 heroin users and 35 people following a methadone treatment program. Observation was carried out in a central district of Barcelona, Spain, with a low socioeconomic level. The results are a useful starting point for generating strategies aimed at preventing HIV transmission among this population on personal, community, and sociostructural levels.

Contraceptive efficacy of a depot progestin and androgen combination in men.

WHO studies provided proof of concept for hormonal male contraception using a prototype androgen-alone regimen. Combined testosterone plus progestin regimens offer more practical promise, but no contraceptive efficacy studies have been completed. The objective of this study was to establish the proof of principle for depot hormonal androgen/progestin combination as a male contraceptive. We performed a contraceptive efficacy study of 55 healthy men in stable fertile relationships seeking a change in contraceptive method. Testosterone (four 200-mg implants, every 4 or 6 months) and 300 mg depot medroxyprogesterone acetate, im, every 3 months were administered. Once sperm output was suppressed (<1 million/ml for 2 consecutive months), men entered a 12-month contraceptive efficacy period, ceasing other contraception. The main outcome measure was contraceptive failure (pregnancy) rate. No pregnancies occurred in 426 person-months (35.5 person-years; 95% confidence limits for contraceptive failure rate, 0-8%/annum), superior to the first year failure rate of condoms, the only reversible male method. Sperm density fell rapidly, so 94% of men entered the efficacy phase by 3 months, with only 2 of 55 (3.6%) men not sufficiently suppressed to enter efficacy. A few men treated with testosterone implants at 6-month intervals demonstrated androgen deficiency symptoms and/or escape of gonadotropin and spermatogenic suppression between months 5 and 6; after a protocol amendment, all men receiving testosterone implants at 4-month intervals avoided androgen deficiency or loss of gonadotropin and sperm output suppression. Recovery was complete (median, 3.6 months to sperm reappearance and 5.0 months to 20 million sperm/ml) in all but one man with an incidental testicular disorder. Discontinuations were for protocol-related reasons (n = 15) or altered personal circumstances (n = 12), but there were no serious adverse effects related to drug exposure. The first male contraceptive efficacy study using a prototype depot androgen/progestin combination demonstrates high contraceptive efficacy with satisfactory short-term safety and recovery of spermatogenesis. Further studies of purpose-developed products are required to extend the overall safety and efficacy experience with depot androgen/progestin combinations, the most promising approach to hormonal male contraception.

Medical student awareness of sexual health is poor.

The aim of the study was to assess sexual health knowledge of medical students. Participants from the student population of an English Medical School (University of Bristol) were asked to fill in a questionnaire on the Internet about sexual health issues. The number of correct responses to each question was analysed according to participants' gender and medical school year. While certain issues relating to sexually transmitted infections, contraception and confidentiality in HIV testing were well understood, there was poor knowledge about the failure rate of condoms, abortion rates and prevalence of chlamydia. Women knew more about the contraceptive pill than men. Although increased years of medical training had some benefit in improving the accuracy of knowledge, this effect was surprisingly small. Most medical students have inaccurate factual knowledge about certain important sexual health issues. We consider this to reflect poorly on sexual health awareness in young people in general. There is need for greater sexual health education for future doctors and for the general public.

Behavioral, health and psychosocial factors and risk for HIV infection among sexually active homosexual men: the Multicenter AIDS Cohort Study.

We examined whether 644 homosexual men who engaged in receptive anal intercourse were at particularly elevated risk for seroconversion if they also possessed specific behavioral, health or psychosocial vulnerability characteristics. Of 11 potential factors examined, heavy drinking, moderate to heavy drug use, and younger age were significantly related to seroconversion. These variables were also associated with an increased number of sexual partners, anonymous sex, and failure to use condoms.

Chlamydia trachomatis screening in family planning centers: a review of cost/benefit evaluations in different countries.

Chlamydia trachomatis is a primary cause of acute or silent salpingitis leading to infertility and ectopic pregnancy. The C. trachomatis epidemic, undiscovered in most cases, spreads, mostly in adolescents, during the years following the onset of sexual activity. As opposed to gonococcal infection which has greatly decreased, C. trachomatis cervical and urethral infection is common in young occidentals. More then 30 different studies covering 200-12,000 subjects screened in family planning centers, college women and men, students and military recruits in different parts of the USA, in Scandinavian countries and France, indicate a prevalence of 5-20% (mean 10%) in apparently healthy young females < 25 years and 5-10% in males. Female prevalence is strongly related to age, being highest (15-20%) in women < 20 years old. Several cost-benefit analyses show that the total cost of the general screening in young populations, which can easily be carried out for women in family planning centers, could save twice the cost of treatment for pelvic inflammatory disease caused by C. trachomatis and six times the total cost of C. trachomatis epidemics if late sequelae are taken into account (tubal infertility treatment, ectopic pregnancy). There is a debate among authors concerning the relative merits of total screening versus selective screening in family planning centers, the most common opinion being to do a total screening of women < 20 years old and selective screening of women 20-30 years of age with at least one risk factor, the most common risk factors being more than one partner in a year, purulent, cervical discharge, failure to use condoms and use of a contraceptive pill. Although the data clearly show that C. trachomatis screening is cost-effective, conducting of the diagnostic laboratory tests used in such screening programs should be carefully evaluated relative to cost, feasibility, specificity and sensitivity and should be adapted to the presumed prevalence in screened populations.

Psychosocial factors as predictors of unsafe sexual practices among young adults.

This study examined the influence of both psychosocial constructs and demographic features on the sexual risk-taking behavior of young adults. Three hundred seventy-four students between the ages of 18 and 29 were drawn from a medium-sized university. All participants were assessed using measures that included the AIDS Coping and Change Survey, the AIDS Psychosocial Scale, and the AIDS Knowledge and Attitudes Survey. Descriptive statistics were calculated for levels of HIV risk behavior (failure to use condoms combined with casual or anonymous sexual partners), HIV/AIDS knowledge, alcohol and drug use, sexual history, and other demographic features. Factor analysis was then used to examine the latent factors associated with HIV risk behavior. All confirmed factors and demographic items that were shown to be significantly correlated with HIV risk behavior were then examined for predictive ability using a regression analysis. Ten factors or variables were found to be predictive of HIV risk behavior, including a Developmental Factor which was found to be moderately predictive of HIV risk behavior. Other predictors included Resistance to Change in response to AIDS; Perceived Risk of exposure, the influence of peer groups, age, alcohol use, marijuana use; a history of infidelity; a younger age of sexual initiation; and a lower self-efficacy.

The neglected health care needs of street youth.

Juveniles who live on the street are often the victims of physical and sexual abuse and family chaos. They have a multitude of health problems such as malnutrition, respiratory infections, sexually transmitted diseases, including human immunodeficiency virus, mental illness, and substance abuse. Health care, if available, is generally fragmented and often not relevant to their needs. Their high-risk existence leads to individual morbidity and has a negative effect on the health of the community. Presently, there is limited research on the health status and health care needs of street youth who are difficult to track and quantify. The findings of a project undertaken by Region IX of the Public Health Service in 1989 to provide technical assistance to three primary care clinics serving street youth in San Francisco are reviewed. Data were collected on demographics, overall health status, sex-related medical problems, mental health, and substance abuse and compared with another group of adolescents in the general population. Street youth were found to have a greater number of problems--both physical and psychological--than the general adolescent population. High-risk behaviors, such as drug abuse and failure to use condoms during sex, make this population especially vulnerable to sexually transmitted diseases, including human immunodeficiency virus. The potential impact on public health is enormous. Adequate access to health services needs to be addressed legislatively.

An epidemiological approach to sexually transmitted diseases--with special reference to contact tracing and screening.

Sexually Transmitted Diseases (STD) are a major health problem all over the world. The diseases are often spread by unsuspecting asymptomatic individuals. One important means of controlling STD is thus the identification of asymptomatic persons. The purposes of this thesis were a) to describe methods of identifying infected individuals through contact tracing and screening, b) to evaluate contact tracing routines, c) to compare epidemiological characteristics of two different groups of chlamydia-infected women and their partners and d) to see if data from contact tracing could be used in a model describing partner choice and STD spread. A microepidemic of penicillinase-producing gonococci was effectively controlled through contact tracing by cooperating counsellors. Serotyping of gonococci and graphic description proved of great help in mapping the contact chain. Contact tracing integrated in the psychosocial long-term care of HIV-infected patients resulted in identification of a great number of previously unidentified individuals. Screening for Chlamydia trachomatis (Ct) among asymptomatic patients of family planning clinics revealed a 7.3% Ct prevalence. Four factors were significantly correlated to the risk of being infected: age 18-23, duration of present relationship less than 1 year, failure to use condoms and no previous history of genital infection. Abstention from testing was especially high in areas with low socio-economic status. In these areas, increased resources for health care are needed. Five different levels of management of Ct infections were compared. Increased measures to verify that reported partners were examined decreased reinfections and after Ct was included in the STD Act more reported partners than before came for examination. Index patients found by chlamydia screening and their partners have a lower average number of recent partners than index patients visiting an STD clinic and their partners. Partners of female patients in the STD clinic group were also more often Ct-positive. The differences between the groups are small and do not justify different ambitions in partner management. Choice of steady partner was rather restricted and choice of casual partner followed a more random pattern. Our data thus do not support a pure random mixing model for STD spread.

Clinical breakage, slippage and acceptability of a new commercial polyurethane condom: a randomized, controlled study.

Although latex remains the primary material for male condoms, a number of condoms made from synthetic materials have appeared in commercial markets in recent years. Published data on the safety and efficacy of these condoms is still limited, but nevertheless synthetic condoms do offer the user a wider choice and may encourage greater use of condoms for contraception and sexual transmitted infection prophylaxis. This paper reports on a study carried out in the Paris region of France on a new, commercial polyurethane condom marketed in Japan as Sagami Original and in Europe as Protex Original. A standard latex condom complying with the European standard for condoms (EN 600:1996) from the same manufacturer was used as the control in the study. The clinical breakage rate for the polyurethane condom was 0.6% (95% confidence interval 0.2-1.4%) compared to 1.3% (95% confidence interval 0.6-2.2%) for the latex condom. The difference was not statistically significant (chi(2) = 1.9, p = 0.168). Clinically significant slippage (complete slippage of the condom off the penis) was 1.1% (95% confidence interval 0.5-1.9%) for the polyurethane condom, compared to 0.5% (95% confidence interval 0.2-1.2%) for the latex; a difference that again was not statistically significant (chi(2) = 1.783, p = 0.182). The polyurethane condom was therefore equivalent to the latex condom in terms of clinical failure rate.

Condom-use errors and problems: a neglected aspect of studies assessing condom effectiveness.

OBJECTIVE: To assess and compare condom-use errors and problems among condom-using university males and females. METHODS: A convenience sample of 260 undergraduates was utilized. Males (n=118) and females (n=142) reported using condoms in the past 3 months for at least one episode of sex (penis in the mouth, vagina, or rectum) with a partner of the other sex. A questionnaire assessed 15 errors and problems associated with condom use that could be observed or experienced by females as well as males. RESULTS: About 44% reported lack of condom availability. Errors that could contribute to failure included using sharp instruments to open condom packages (11%), storing condoms in wallets (19%), and not using a new condom when switching from one form of sex to another (83%). Thirty-eight percent reported that condoms were applied after sex had begun, and nearly 14% indicated they removed condoms before sex was concluded. Problems included loss of erection during condom application (15%) or during sex (10%). About 28% reported that condoms had either slipped off or broken. Nearly 19% perceived, at least once, that their condom problems necessitated the use of a new condom. Few differences were observed in errors and problems between males and females. CONCLUSIONS: Findings suggest that condom-use errors and problems may be quite common and that assessment of errors and problems do not necessarily need to be gender specific. Findings also suggest that correcting "user failure" may represent an important challenge in the practice of preventive medicine.
