Teenage conceptions, abortions, and births in England, 1994-2003, and the national teenage pregnancy strategy.

BACKGROUND: The aim of this study was to quantify the change in the number of conceptions and abortions among women younger than 18 years in England in relation to the government's national teenage pregnancy strategy. METHODS: We undertook geographic analysis of data for 148 top-tier local authority areas. The main outcomes were changes in under-18 conceptions, abortions, and births between the 5-year period before implementation of the strategy (1994-98) and the period immediately after implementation (1999-2003). FINDINGS: The number of teenage conceptions peaked in 1998, then declined after the implementation in 1999 of the teenage pregnancy strategy. Under-18 conception rates fell by an average of 2.0% (95% CI 1.8 to 2.2) per year between 1998 and 2003, below the rate needed to achieve the target of 50% reduction by 2010. The net change between 1994-98 and 1999-2003 was a fall in conceptions of 3.2% (2.6 to 3.9) or 1.4 per 1000 women aged 15-17 years, a rise in abortions of 7.5% (6.5 to 8.6) or 1.4 per 1000, and a fall in births of 10.6% (9.9 to 11.3) or 2.8 per 1000. The change in the number of conceptions was greater in deprived and more rural areas, and in those with lower educational attainment. The change was greater in areas where services and access to them were poorer, but greater where more strategy-related resources had been targeted. INTERPRETATION: The decline in under-18 conception and birth rates since 1998 and evidence that the declines have been greatest in areas receiving higher amounts of strategy-related funding provides limited evidence of the effect of England's national teenage pregnancy strategy. The full effect of local prevention will be clear only with longer observation, and substantial further progress is needed to remedy England's historically poor international position in teenage conceptions.

Sexual behaviour in context: a global perspective.

Research aimed at investigating sexual behaviour and assessing interventions to improve sexual health has increased in recent decades. The resulting data, despite regional differences in quantity and quality, provide a historically unique opportunity to describe patterns of sexual behaviour and their implications for attempts to protect sexual health at the beginning of the 21st century. In this paper we present original analyses of sexual behaviour data from 59 countries for which they were available. The data show substantial diversity in sexual behaviour by region and sex. No universal trend towards earlier sexual intercourse has occurred, but the shift towards later marriage in most countries has led to an increase in premarital sex, the prevalence of which is generally higher in developed countries than in developing countries, and is higher in men than in women. Monogamy is the dominant pattern everywhere, but having had two or more sexual partners in the past year is more common in men than in women, and reported rates are higher in industrialised than in non-industrialised countries. Condom use has increased in prevalence almost everywhere, but rates remain low in many developing countries. The huge regional variation indicates mainly social and economic determinants of sexual behaviour, which have implications for intervention. Although individual behaviour change is central to improving sexual health, efforts are also needed to address the broader determinants of sexual behaviour, particularly those that relate to the social context. The evidence from behavioural interventions is that no general approach to sexual-health promotion will work everywhere and no single-component intervention will work anywhere. Comprehensive behavioural interventions are needed that take account of the social context in mounting individual-level programmes, attempt to modify social norms to support uptake and maintenance of behaviour change, and tackle the structural factors that contribute to risky sexual behaviour.

Learning about sex: results from Natsal 2000.

To date, the focus of sex education research has tended to be on the effect of education on behavioral outcomes. There is little data on the felt needs of young people, how well they are met, and how provision might be improved. Here we report on main source of information about sexual matters, adequacy of knowledge, further needs, and preferred source of additional information, using data from a probability sample survey of people aged 16 to 44 years in Britain (Natsal 2000). A total of 11,161 participants (4,762 men and 6,399 women) were interviewed. The response rate was 65.4%. The results show that despite the assumed worldliness and sophistication of young people about sexual matters, there is a great deal of self-perceived ignorance among them. Parents and schools are the preferred source of further information. We need to enable parents to provide information to their children, especially their sons.

Sociodemographic and sexual health profile of users of emergency hormonal contraception: data from a British probability sample survey.

OBJECTIVE: This study aimed to identify factors associated with the use of emergency hormonal contraception (EHC). METHODS: Data from a probability sample survey of 12,110 men and women aged 16-44 living in Britain were used for this study; 5916 women were selected as potential users of EHC, defined as women reporting at least one male partner in the year prior to the survey. RESULTS: Of the 5916 women, 2.3% reported EHC use in the previous year. EHC use was more common among younger, single women, those with more than one sexual partner in the past year and those using condoms for contraception. It was significantly associated with experience of abortion (odds ratio adjusted for age, marital status and number of male partners: 2.40) but not with sexually transmitted infection (STI) diagnosis. CONCLUSIONS: The use of EHC identifies a group of women at increased risk of unplanned pregnancy and condom use but not STI acquisition. Provision of information on more reliable contraceptive methods is needed to reduce the risk of unplanned pregnancy recurrence.

Ethnic variations in sexual activity and contraceptive use: national cross-sectional survey.

OBJECTIVES: Our objective was to compare data on contraceptive use in relation to reported sexual activity in women from different minority ethnic groups. DESIGN: We analyzed the National Survey of Sexual Attitudes and Lifestyles 2000. SUBJECTS: Women aged 16-44 years, numbering 6932 and residing in Britain, participated in this study. MAIN OUTCOME MEASURES: Our main outcome measures are as follows: percentage of women reporting sexual activity, use of contraception and type of contraception (hormonal, barrier or permanent methods). RESULTS: Overall, fewer women from the UK's four main ethnic minority groups reported recent sexual activity, compared with white women. Among sexually active women, contraceptive use was significantly lower in all ethnic minority groups than in white women, but this pattern differed according to marital status. In ever-married or cohabiting women, lower contraceptive use was reported by Indian (78%) and Pakistani women (74%) than by other groups. Among single women, black Caribbean (88%) and black African (82%) women reported using less contraception compared with white (95%) and Indian (100%) women. Women from all ethnic minority groups were less likely than white women to report using hormonal contraception and permanent methods and were more likely to use barrier methods. The differences between ethnic groups remained significant after adjusting for educational achievement and parity. Deprivation and acculturation did not account for the use of contraception or the type of contraceptive method used. CONCLUSION: Sexually active married Pakistani and Indian women reported the lowest overall use of contraception. Among sexually active single women, black African and black Caribbean women reported levels of contraceptive use that were lower than those reported by white women. Sexually active women from all four minority ethnic groups were less likely than white women to use reliable methods of contraception.

First sexual partnerships--age differences and their significance: empirical evidence from the 2000 British National Survey of Sexual Attitudes and Lifestyles ('Natsal 2000').

PURPOSE: To describe variations in age differences (ADs) between partners at first heterosexual intercourse and to examine associations between this AD, sociodemographic characteristics, and circumstances of first heterosexual intercourse, by gender. METHODS: A total of 3277 men and 4734 women aged 25-44 years who reported ever having heterosexual intercourse in a probability survey of the British population to obtain an unbiased sample of ADs at first intercourse. Face-to-face interviews collected sociodemographic data and information on first intercourse. Gender-specific cumulative distributions of ADs categorized respondents reporting relatively younger first partners (below fifth percentile) and those reporting relatively older first partners (above 95th percentile). RESULTS: Relatively older first partners were six years older than men and 10 years older than women. Relatively younger first partners were three years younger than men and one year younger than women. Men and women with relatively older first partners were more likely to have just met their partner (odds ratios adjusted for sociodemographic characteristics [AOR] 1.8, 95% confidence interval [CI] 1.2-2.7, and 3.1, 95% CI 2.1-4.6, respectively); had a more willing first partner (AOR 2.1, 95% CI 1.2-3.8, and 1.6, 95% CI 1.2-2.2, respectively); not used condoms at first sex (AOR 1.9, 95% CI 1.2-3.0, and 1.5, 95% CI 1.1-2.0, respectively); and reported a non-autonomous reason for first sex (AOR 1.6, 95% CI 1.1-2.4, women only). Men with relatively younger first partners were more likely to regret the timing of the first occasion (AOR 2.1, 95% CI 1.0-4.5). CONCLUSIONS: First partnerships involving relatively older or younger partners are associated with adverse circumstances of first intercourse. Condoms and other reliable contraception are less likely to be used, and age differences may reflect unequal power relations. Promoting effective communication and negotiation skills may be particularly important for those with relatively older or younger first partners.

Epidemiological correlates of asymptomatic gonorrhea.

OBJECTIVES: To assess correlates of asymptomatic gonorrhea among patients attending Genitourinary Medicine Clinics participating in the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP) in England for 2001-2003. STUDY DESIGN: GRASP is a sentinel surveillance program that monitors antimicrobial resistance to Neisseria gonorrhoeae. Data collection occurs annually in June to August each year. RESULTS: Women with previously diagnosed gonorrhea had decreased odds of asymptomatic gonococcal infection, as did women diagnosed with other sexually transmitted infections (all except chlamydia, syphilis, herpes, and warts). Heterosexual men, but not women, coinfected with chlamydia had significantly higher likelihood of being diagnosed with asymptomatic gonorrhea, as did homosexual men coinfected with syphilis and warts. CONCLUSION: The heterogeneity in correlates of asymptomatic gonorrhea has implications for screening in clinical settings. Such findings also depend on the extent of testing on sexually transmitted infections from different sites of infection, which has particular relevance in homosexual men and would thus need to be investigated in other studies.

Increased condom use at sexual debut in the general population of Slovenia and association with subsequent condom use.

OBJECTIVES: To describe the extent of condom use at first heterosexual intercourse (FHI) in the general population of Slovenia, identify associated factors and assess the association with subsequent use. DESIGN: Cross-sectional survey comprising the first Slovenian National Survey of Sexual Lifestyles, Attitudes and Health. METHODS: Data were collected during 1999-2001 from a probability sample of the general population aged 18-49 years. Statistical methods for complex survey data were used to carry out weighted analyses. RESULTS: Condom use at FHI was reported by 23.6% of men and 21.3% of women. The more recently they experienced FHI, the more likely respondents were to report condom use (71.7% of men; 63.8% of women with FHI during 1995-1999). Men with FHI at age 18 or older and those with higher levels of education were more likely to use a condom and those who lost control (because drunk or carried away by feelings) less likely. Men seem to have more control over condom use at FHI than women. Sexually active men and women who used condom at FHI were 11 and 2.5 times more likely to consistently use condoms during the month preceding the interview. CONCLUSIONS: Currently, the majority of Slovenian men and women use protection against HIV, other sexually transmitted infections, and unplanned conception at FHI. The steep increase over time in condom use at FHI suggests that HIV-related condom use promotion has had an impact on preventive behaviours and should be sustained, especially since condom use at FHI predicts subsequent use.

Reported sexually transmitted disease clinic attendance and sexually transmitted infections in britain: prevalence, risk factors, and proportionate population burden.

BACKGROUND: We examined attendance at sexually transmitted disease (STD) clinics and the prevalence, distribution, and associated demographic and behavioral factors of self-reported sexually transmitted infections (STIs) in a population survey of sexual attitudes and lifestyles. METHODS: We analyzed data from stratified probability sample surveys obtained through the British National Surveys of Sexual Attitudes and Lifestyles (Natsal), which was undertaken in 1990 (n=13,765) and 2000 (n=11,161) among men and women aged 16-44 years. National STD surveillance data for 1999 were used to determine disease- and risk factor-specific proportionate population burden (PPB). RESULTS: Between 1990 and 2000, the number of subjects who reported having attended an STD clinic during the past 5 years increased from 4.3% to 7.6% among men and from 3.3% to 6.6% among women. In 2000, 3.0% of men and 4.0% of women reported having received a diagnosis of an STI during the past 5 years; 77.6% of men and 60.3% of women with an STI had attended an STD clinic. Reported STI acquisition was independently associated with age, increasing numbers of sex partners, male homosexual partners, and partners from abroad (for women only). Of all reported STIs during the past 5 years (PPB, 10.2%), 10.2% were reported by the 2.9% of men who reported having had homosexual partners during the past 5 years. Of all reported STIs in the past 5 years (PPB, 41.6%), 41.6% were reported by the 4.0% of women who reported having > or =10 sex partners during that time. Analysis of national STI surveillance data showed that the PPB for new episodes of Chlamydia trachomatis diagnosed among homosexual men was 2.8%, that for gonorrhea was 17.4%, and that for syphilis was 32.1%. CONCLUSIONS: Numbers and types of sexual partnerships remain the dominant individual and population risk factors for STI acquisition. Combined population behavior and surveillance data demonstrate the high PPB for STIs attributable to key risk factors. PPB may be a useful indicator of epidemic "phase" and may help target resources and guide prevention strategies.

Investigating the relationship between HIV testing and risk behaviour in Britain: National Survey of Sexual Attitudes and Lifestyles 2000.

OBJECTIVES: To estimate the prevalence of, and identify factors associated with, HIV testing in Britain. DESIGN: A large, stratified probability sample survey of sexual attitudes and lifestyles. METHODS: A total of 12,110 16-44 year olds completed a computer-assisted face-to-face interview and self-interview. Self-reports of HIV testing, i.e. the timing, reasons for and location of testing, were included. RESULTS: A total of 32.4% of men and 31.7% of women reported ever having had an HIV test, the majority of whom were tested through blood donation. When screening for blood donation and pregnancy were excluded, 9.0% of men and 4.6% of women had had a voluntary confidential HIV test (VCT) in the past 5 years. However, one third of injecting drug users and men who have sex with men had a VCT in the past 5 years. VCT in the past 5 years was significantly associated with age, residence, ethnicity, self-perceived HIV risk, reporting greater numbers of sexual partners, new sexual partners from abroad, previous sexually transmitted infection diagnosis, and injecting non-prescribed drugs for men and women, and same-sex partners (men only). Whereas sexually transmitted disease clinics were important sites for VCT, general practice accounted for almost a quarter of VCT. CONCLUSION: HIV testing is relatively common in Britain; however, it remains largely associated with population-based blood donation and antenatal screening programmes. In contrast, VCT remains highly associated with high-risk (sexual or drug-injecting) behaviours or population sub-groups at high risk. Strategies to reduce undiagnosed prevalent HIV infection will require further normalization and wider uptake of HIV testing.

Chlamydia trachomatis testing in the second British national survey of sexual attitudes and lifestyles: respondent uptake and treatment outcomes.

BACKGROUND: Noninvasive molecular tests for bacterial sexually transmitted infections (STIs) provide new opportunities for testing in nonclinical settings. Little information is available on the outcomes when applied to asymptomatic sex survey participants. OBJECTIVE: The objective of this study was to examine patient treatment preferences and partner notification outcomes among Chlamydia trachomatis-positive cases identified in the 2000 national survey of sexual attitudes and lifestyles (Natsal 2000), and factors associated with providing a urine sample. METHODS: The authors conducted a stratified probability sample survey of 11,161 men and women aged 16 to 44 years residing in Britain using computer-assisted self-interviews. Urine testing was performed for C. trachomatis offered to a random half of sexually active respondents aged 18 to 44 using ligase chain reaction. Notification, treatment, and follow up of ligase chain reaction-positive respondents were undertaken. RESULTS: A total of 5105 respondents were invited to provide a urine sample. A total of 3628 (71%) agreed and 3608 samples were successfully tested. Willingness to provide a urine sample was significantly higher among those reporting previous homosexual experience, heterosexual anal sex, and STI diagnosis. Seventy-three respondents (31 men and 42 women) were diagnosed with genital chlamydial infection. Sixty-five (89%) responded to notification of their infection and were recommended for treatment and partner notification. Fifty (77%) respondents preferred to be seen by their general practitioner and 15 (23%) by their local genitourinary medicine clinic. Although physician feedback on treatment and partner notification outcomes was obtained for only half (n = 34) of respondents, follow-up respondent interviews confirmed that a total of 49 (75%) respondents underwent this process. INTERPRETATION: In this community-based survey, the rate of provision of urine samples was high, and those who provided samples were found to be at somewhat greater risk of infection on average. This was accounted for in estimating population chlamydia prevalence. The authors found that treatment and partner notification of newly diagnosed infections can be successfully achieved in STI prevalence studies.

Changes in the circumstances of young mothers in Britain: 1990 to 2000.

OBJECTIVES: To assess changes between 1990 and 2000 in the circumstances of women who became mothers before the age of 18. DESIGN: Two cross sectional probability sample surveys of the general population carried out in 1989-1991 (Natsal 1990) and 1999-2001 (Natsal 2000). SETTING: British households. PARTICIPANTS: Women aged 18 to 27 years at time of survey (Natsal 1990: 2575, Natsal 2000: 1757). MAIN OUTCOME MEASURES: Educational attainment, participation in education/work or training, living in social housing, social class, living as lone adult, parity, ill health, and health related behaviours at the time of the interview. RESULTS: The proportion of women who were sexually active before 18 increased between 1990 and 2000 from 58.9% to 71.3% (p<0.0001). There was no significant change in the proportion who had a child before the age of 18 (4.7% in 1990, 5.3% in 2000, p=0.390). The proportion who had attained no educational qualifications and were not participating in education/work or training was significantly lower in 2000 than in 1990 for all women aged 18-27, but higher among those who were mothers before age 18, although the relative difference was not statistically significant. The proportion living in social housing or reporting a recent long term illness at time of interview was higher and this trend was more pronounced among women who did not experience motherhood before 18 than those who did, but the differences between these groups of women were not statistically significant. CONCLUSION: Motherhood before the age of 18 continues to be related to a variety of adverse circumstances in adult life, including lack of educational attainment, not being in education/work or training, lone parenthood, and a reduced likelihood of home ownership. There is little evidence of improvement in the circumstances of young mothers between 1990 and 2000 despite improvements in life chances among young women in general.

Increasing prevalence of male homosexual partnerships and practices in Britain 1990-2000: evidence from national probability surveys.

OBJECTIVES: To estimate the prevalence and timing of homosexual experience among British men; to explore the patterns of sexual practices and partnerships in 2000, and behavioural and attitudinal changes between 1990 and 2000 among men who have sex with men (MSM). DESIGN: Two large, stratified probability sample surveys of the general population. METHODS: Trained interviewers administered a combination of face-to-face and self-completion questionnaires to men aged 16 to 44 years resident in Britain (n = 6000 in 1990 and n = 4762 in 2000). RESULTS: In 2000, 2.8% of British men reported sex with men in the past 5 years. 46.0% of MSM reported five or more partners in the past 5 years, and 59.8% reported unprotected anal intercourse in the past year. A total of 33.0% of MSM reported one or more female partner(s) in the past year. In comparison with 1990, there was a significant increase in the proportion of MSM in the population in 2000, and among these men, in the proportion reporting receptive anal intercourse in the past year [age-adjusted odds ratio (OR), 2.08; 95% confidence interval (CI), 1.08-4.00], but no significant change in self-perceived HIV-risk (age-adjusted OR, 1.11; 95% CI, 0.49-2.51) or HIV testing in past 5 years (age-adjusted OR, 1.14; 95% CI, 0.57-2.25). CONCLUSIONS: Evidence of increasing prevalence of homosexual intercourse among the British male population coupled with increases in some HIV-risk behaviours among MSM suggests overall increasing numbers at risk in the population. Although these changes may partly reflect an increased willingness to report these behaviours, our results are consistent with increasing incidence of sexually transmitted infections and behavioural surveillance data.

Providing information for young people in sexual health clinics: getting it right.

BACKGROUND: The need to improve the quality and availability of information on sexual health is identified as a key element in achieving the aims set out in the National Strategy for Sexual Health and HIV. Providing information about sexual health to young people poses particular challenges because of the sensitive nature of the issues and because of the difficulties that young people may face in sourcing information and asking questions of professionals.

What is a 'planned' pregnancy? Empirical data from a British study.

The terms "planned", "unplanned", "intended", "unintended", "wanted" and "unwanted" are often used in relation to pregnancy in health policy, health services and health research. This paper describes the findings relating to women's understanding of these terms from the qualitative stage of a British study. We found that when discussing the circumstances of their pregnancies, women tended not to use the above terms spontaneously. When asked to explain the terms, women were able to do so but there was considerable variation in understanding. Most, but not all, were able to apply the terms. Women applied the term "planned" only if they had met four key criteria. Intending to become pregnant and stopping contraception were not sufficient criteria, in themselves, to apply the term; partner agreement and reaching the right time in terms of lifestyle/life stage were also necessary. In contrast, "unplanned" was a widely applied term and covered a variety of circumstances of pregnancy. The other terms were less favoured, "unwanted" being positively disliked. We recommend that survey questions eliciting information on women's circumstances of pregnancy do not rely on the above terms in isolation and, further, that a more circumspect use of the terms in policy and clinical settings is required.

The impact of the quality of family planning services on safe and effective contraceptive use: a systematic literature review.

The aim of this review is to identify the features of family planning service provision that are influential in ensuring safe and appropriate contraceptive use and optimal effectiveness of user-dependent methods. A systematic search was carried out of the published and unpublished studies available up to December 1997 that examined the relationship between family planning service provision and contraceptive use. Articles that reported primary data on long-term outcomes were scored by at least two of the authors of the present study. Particular attention was paid to evaluating methods of measuring quality of care. A total of 142 articles were identified, but only 16 reported primary data relating to long-term outcomes. The quality of provider--client exchanges was found to have a net incremental effect on contraceptive use. Evidence of effectiveness of methods to improve uptake, continuation of method use, and safe and appropriate use of fertility control is scant. The evidence that is available indicates that training in communication with clients (particularly about side-effects of contraceptive methods) and an emphasis on client choice are key components of effective interventions. The tasks of listening to clients, and tailoring services to local needs, are crucial to the success of family planning service provision.
