Salivary Testosterone and Sexual Function and Behavior in Men and Women: Findings from the Third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3).

Using data from the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3) we examined associations between salivary testosterone (Sal-T) and sexual function and behavior. Single morning saliva samples were self-collected from a subsample of participants aged 18-74 years and analyzed using mass spectrometry. 1,599 men and 2,123 women were included in the analysis (40.6% of those invited to provide a sample). We adjusted for confounders in a stepwise manner: in model 1 we adjusted for age only; model 2 for age, season and relationship status, and model 3 we added BMI and self-reported health. In the fully adjusted models, among men, Sal-T was positively associated with both partnered sex (vaginal sex and concurrent partners) and masturbation. Among women, Sal-T was positively associated with masturbation, the only association with partnered sex was with ever experience of same-sex sex. We found no clear association between Sal-T and sexual function. Our study contributes toward addressing the sparsity of data outside the laboratory on the differences between men and women in the relationship between T and sexual function and behavior. To our knowledge, this is the first population study, among men and women, using a mass spectrometry Sal-T assay to do so.

Painful sex (dyspareunia) in women: prevalence and associated factors in a British population probability survey.

OBJECTIVE: To estimate the prevalence of painful sex among women in Britain, and to explore associated sexual, relationship and health factors that should be considered in assessment. DESIGN: Multi-stage, clustered and stratified population probability sample survey, using computer-assisted self-interview. Sample frame was the British Postcode Address File. SETTING: Participants interviewed at home between 2010 and 2012. SAMPLE: A total of 15 162 adults aged 16-74 years (8869 women). Data reported from 6669 sexually active women. METHODS: Age-adjusted logistic regressions to examine associations between painful sex and indicators of sexual, relational, mental and physical health. MAIN OUTCOME MEASURE: Physical pain as a result of sex for ≥3 months in the past year, plus measures of symptom severity. RESULTS: Painful sex was reported by 7.5% (95% CI 6.7-8.3) of sexually active women, of whom one-quarter experienced symptoms very often or always, for ≥6 months, and causing distress. Reporting painful sex was strongly associated with other sexual function problems, notably vaginal dryness (age adjusted odds ratio 7.9; 6.17-10.12), anxiety about sex (6.34; 4.76-8.46) and lacking enjoyment in sex (6.12; 4.81-7.79). It was associated with sexual relationship factors [such as not sharing same level of interest in sex (2.56; 1.97-3.33)], as well as with adverse experiences such as non-volitional sex (2.17; 1.68-2.80). Associations were also found with measures of psychological and physical health, including depressive symptoms (1.68; 1.28-2.21). CONCLUSION: Painful sex is reported by a sizeable minority of women in Britain. Health professionals should be supported to undertake holistic assessment and treatment which takes account of the sexual, relationship and health context of symptoms. TWEETABLE ABSTRACT: Painful sex-reported by 7.5% of women in Britain-is linked to poorer sexual, physical, relational and mental health.

How can we objectively categorise partnership type? A novel classification of population survey data to inform epidemiological research and clinical practice.

BACKGROUND: Partnership type is a determinant of STI risk; yet, it is poorly and inconsistently recorded in clinical practice and research. We identify a novel, empirical-based categorisation of partnership type, and examine whether reporting STI diagnoses varies by the resulting typologies. METHODS: Analyses of probability survey data collected from 15 162 people aged 16-74 who participated in Britain's third National Survey of Sexual Attitudes and Lifestyles were undertaken during 2010-2012. Computer-assisted self-interviews asked about participants' ≤3 most recent partners (N=14 322 partners/past year). Analysis of variance and regression tested for differences in partnership duration and perceived likelihood of sex again across 21 'partnership progression types' (PPTs) derived from relationship status at first and most recent sex. Multivariable regression examined the association between reporting STI diagnoses and partnership type(s) net of age and reported partner numbers (all past year). RESULTS: The 21 PPTs were grouped into four summary types: 'cohabiting', 'now steady', 'casual' and 'ex-steady' according to the average duration and likelihood of sex again. 11 combinations of these summary types accounted for 94.5% of all men; 13 combinations accounted for 96.9% of all women. Reporting STI diagnoses varied by partnership-type combination, including after adjusting for age and partner numbers, for example, adjusted OR: 6.03 (95% CI 2.01 to 18.1) for men with two 'casual' and one 'now steady' partners versus men with one 'cohabiting' partner. CONCLUSIONS: This typology provides an objective method for measuring partnership type and demonstrates its importance in understanding STI risk, net of partner numbers. Epidemiological research and clinical practice should use these methods and results to maximise individual and public health benefit.

Salivary Testosterone Levels and Health Status in Men and Women in the British General Population: Findings from the Third National Survey of Sexual Attitudes and Lifestyles (Natsal-3).

CONTEXT: Salivary T (Sal-T) measurement by liquid chromatography-tandem mass spectroscopy resents the opportunity to examine health correlates of Sal-T in a large-scale population survey. OBJECTIVE: This study sought to examine associations between Sal-T and health-related factors in men and women age 18-74 years. DESIGN AND SETTING: Morning saliva samples were obtained from participants in a cross-sectional probability-sample survey of the general British population (Natsal-3). Self-reported health and lifestyle questions were administered as part of a wider sexual health interview. PARTICIPANTS: Study participants included 1599 men and 2123 women. METHODS: Sal-T was measured using liquid chromatography-tandem mass spectroscopy. Linear regression was used to examine associations between health factors and mean Sal-T. RESULTS: In men, mean Sal-T was associated with a range of health factors after age adjustment, and showed a strong independent negative association with body mass index (BMI) in multivariable analysis. Men reporting cardiovascular disease or currently taking medication for depression had lower age-adjusted Sal-T, although there was no association with cardiovascular disease after adjustment for BMI. The decline in Sal-T with increasing age remained after adjustment for health-related factors. In women, Sal-T declined with increasing age; however, there were no age-independent associations with health-related factors or specific heath conditions with the exception of higher Sal-T in smokers. CONCLUSIONS: Sal-T levels were associated, independently of age, with a range of self-reported health markers, particularly BMI, in men but not women. The findings support the view that there is an age-related decline in Sal-T in men and women, which cannot be explained by an increase in ill health. Our results demonstrate the potential of Sal-T as a convenient measure of tissue androgen exposure for population research.

Prevalence of infertility and help seeking among 15 000 women and men.

STUDY QUESTION: What is the prevalence of infertility and of help seeking among women and men in Britain? SUMMARY ANSWER: One in eight women and one in ten men aged 16-74 years had experienced infertility, defined by unsuccessfully attempting pregnancy for a year or longer, and little more than half of these people sought medical or professional help. WHAT IS KNOWN ALREADY: Estimates of infertility and help seeking in Britain vary widely and are not easily comparable because of different definitions and study populations. STUDY DESIGN, SIZE, DURATION: A cross-sectional population survey was conducted between 2010 and 2012 with a sample of 15 162 women and men aged 16-74 years. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants completed the Natsal-3 questionnaire, using computer-assisted personal interviewing (CAPI) and computer-assisted self-interview (CASI). MAIN RESULTS AND THE ROLE OF CHANCE: The reported prevalence of infertility was 12.5% (CI 95% 11.7-13.3) among women and 10.1% (CI 95% 9.2-11.1) among men. Increased prevalence was associated with later cohabitation with a partner, higher socio-economic status and, for those who had a child, becoming parents at older ages. The reported prevalence of help seeking was 57.3% (CI 95% 53.6-61.0) among women and 53.2% (CI 95% 48.1-58.1) among men. Help seekers were more likely to be better educated and in higher status occupations and, among those who had a child, to have become parents later in life. LIMITATIONS, REASONS FOR CAUTION: These data are cross-sectional so it is not possible to establish temporality or infer causality. Self-reported data may be subject to recall bias. WIDER IMPLICATIONS OF THE FINDINGS: The study provides estimates of infertility and help seeking in Britain and the results indicate that the prevalence of infertility is higher among those delaying parenthood. Those with higher educational qualifications and occupational status are more likely to consult with medical professionals for fertility problems than others and these inequalities in help seeking should be considered by clinical practice and public health.

Investigating the relationship between substance use and sexual behaviour in young people in Britain: findings from a national probability survey.

BACKGROUND: Health risk behaviours are prominent in late adolescence and young adulthood, yet UK population-level research examining the relationship between drug or alcohol use and sexual health and behaviour among young people is scarce, despite public health calls for an integrated approach to health improvement. Our objective was to further our understanding of the scale of and nature of any such relationship, using contemporary data from Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3). METHODS: Analyses of data from Natsal-3, a stratified probability survey of 15 162 men and women (3869 aged 16-24 years), undertaken in 2010-2012, using computer-assisted personal interviewing, were carried out. Logistic regression was used to explore associations between reporting (1) frequent binge drinking (≥weekly), (2) recent drug use (within past 4 weeks) or (3) multiple (both types of) substance use, and key sexual risk behaviours and adverse sexual health outcomes. We then examined the sociodemographic profile, health behaviours and attitudes reported by 'risky' young people, defined as those reporting ≥1 type of substance use plus non-condom use at first sex with ≥1 new partner(s), last year. RESULTS: Men and women reporting frequent binge drinking or recent drug use were more likely to report: unprotected first sex with ≥1 new partner(s), last year; first sex with their last partner after only recently meeting; emergency contraception use (last year) and sexually transmitted infection diagnosis/es (past 5 years). Associations with sexual risk were frequently stronger for those reporting multiple substance use, particularly among men. The profile of 'risky' young people differed from that of other 16-24 years old. CONCLUSIONS: In this nationally representative study, substance use was strongly associated with sexual risk and adverse sexual health outcomes among young people. Qualitative or event-level research is needed to examine the context and motivations behind these associations to inform joined-up interventions to address these inter-related behaviours.

Trends in the use of emergency contraception in Britain: evidence from the second and third National Surveys of Sexual Attitudes and Lifestyles.

OBJECTIVE: To examine the changes in the prevalence of, and the factors associated with, the use of emergency contraception (EC) in Britain between 2000 and 2010, spanning the period of deregulation and increase in pharmacy supply. DESIGN: Cross-sectional probability sample surveys. SETTING AND POPULATION: British general population. METHODS: Data were analysed from the second and third British National Surveys of Sexual Attitudes and Lifestyles (Natsal), undertaken in 1999-2001 and 2010-12. Univariate and logistic regression analyses were used to measure change in EC use amongst sexually active women aged 16-44 years not intending pregnancy. MAIN OUTCOME MEASURES: Prevalence of EC use and factors associated with use. RESULTS: Of the 5430 women surveyed in 1999-2001 and the 4825 women surveyed in 2010-12, 2.3 and 3.6%, respectively, reported using EC in the year prior to interview (P = 0.0019 for change over time). The prevalence of EC use increased amongst single women and those with higher educational attainment (adjusted odds ratio, aOR 1.51; 95% confidence interval, 95% CI 1.04-2.20; P = 0.0308). Increases in EC use were generally greater among women without behavioural risk factors, such as those with no history of abortion within 5 years (aOR 1.57; 95% CI 1.17-2.12; P = 0.0029), or those whose first heterosexual intercourse occurred after the age of 16 years (aOR 1.68; 95% CI 1.21-2.35; P = 0.0021). The increase in EC use was also more marked among women usually accessing contraception from retail sources than among those doing so from healthcare sources, which may reflect a use of condoms amongst EC users. CONCLUSION: The increase in EC use among women in Britain in the first decade of the 21st century was associated with some, but not all, risk factors for unplanned pregnancy. Advice and provision may need to be targeted at those at highest risk of unplanned pregnancy. TWEETABLE ABSTRACT: Despite pharmacy access, only a small rise in emergency contraception use has been seen in Britain over 10 years.

Views and experiences of men who have sex with men on the ban on blood donation: a cross sectional survey with qualitative interviews.

OBJECTIVE: To explore compliance with the UK blood services' criterion that excludes men who have had penetrative sex with a man from donating blood, and to assess the possible effects of revising this policy. DESIGN: A random location, cross sectional survey followed by qualitative interviews. SETTING: Britain. PARTICIPANTS: 1028 of 32,373 men in the general population reporting any male sexual contact completed the survey. Additional questions were asked of a general population sample (n=3914). Thirty men who had had penetrative sex with a man participated in the qualitative interviews (19 who had complied with the blood services' exclusion criterion and 11 who had not complied). Main outcome measure Compliance with the blood services' lifetime exclusion criterion for men who have had penetrative sex with a man. RESULTS: 10.6% of men with experience of penetrative sex with a man reported having donated blood in Britain while ineligible under the exclusion criterion, and 2.5% had donated in the previous 12 months. Ineligible donation was less common among men who had had penetrative sex with a man recently (in previous 12 months) than among men for whom this last occurred longer ago. Reasons for non-compliance with the exclusion included self categorisation as low risk, discounting the sexual experience that barred donation, belief in the infallibility of blood screening, concerns about confidentiality, and misunderstanding or perceived inequity of the rule. Although blood donation was rarely viewed as a "right," potential donors were seen as entitled to a considered assessment of risk. A one year deferral since last male penetrative sex was considered by study participants to be generally feasible, equitable, and acceptable. CONCLUSIONS: A minority of men who have sex with men who are ineligible to donate blood under the current donor exclusion in Britain have nevertheless done so in the past 12 months. Many of the reasons identified for non-compliance seem amenable to intervention. A clearly rationalised and communicated one year donor deferral is likely to be welcomed by most men who have sex with men.

Attitudes and first heterosexual experiences among Indians and Pakistanis in Britain: evidence from a national probability survey.

We compare attitudes, experiences of learning about sex and first intercourse among Indians (n = 393) and Pakistanis (n = 365) using a probability survey of Britain's general population aged 16-44 years conducted during 1999-2001 (n = 12,110). Higher proportions of Pakistanis (64.6%) and Indians (28.1%) reported religion as 'very important' versus 6.2% of other ethnicities. Pakistanis were more conservative in their attitudes, e.g. reporting premarital sex as wrong (adjusted odds ratios [AORs] for sociodemographic differences, 4.71 [men] and 6.59 [women]). Pakistanis were more likely to be married at first sex (AORs 6.2 [men] and 9.53 [women]), yet men were more likely than women to be in non-marital relationships at this time (69.4% versus 25.2%). Pakistani men and women and Indian women were more likely to report not using reliable contraception at first sex relative to others (AORs 2.33, 3.16 and 1.90, respectively). Pakistani and Indian women were more likely than others to report school lessons as their main source of sex education (AORs 2.23 and 1.77) and not discussing sex with their parents during adolescence (AORs 2.04 and 2.62). These unique data have implications for ensuring that sex and relationship education and health promotion messages are appropriately planned, targeted and delivered to benefit Pakistanis and Indians.

HIV prone occupational exposures: epidemiology and factors associated with initiation of post-exposure prophylaxis.

BACKGROUND: Occupational exposures to bloodborne viruses are very common. Whilst occupational HIV transmissions are rare, the serious physical, psychological and cost implications of potential transmission make this an important public health topic. European and UK guidelines recommend HIV post-exposure prophylaxis (PEP) as a valuable tool of preventing occupational HIV infection. Yet one in five UK healthcare workers did not initiate PEP despite having been exposed to an HIV-positive source patient. The aim of the study is to examine factors associated with PEP uptake behaviour. METHODS: The study is based on an analysis of the UK Health Protection Agency surveillance database of 'Significant Occupational Exposures to Bloodborne Viruses in Healthcare Workers'. Associations between possible predicting factors and PEP-uptake have been examined with univariate analysis and logistic regression modelling. RESULTS: Univariate analysis and logistic regression found significant associations between PEP-uptake and visible blood on the device (p<0.0001) and a linear relationship with increasing injury depth (p<0.0001). Doctors were significantly more likely to start PEP than nurses (OR 1.88, 1.16; 3.02). Multiple imputation of missing values did not significantly alter these results. CONCLUSIONS: PEP-uptake was associated with known transmission risk factors, suggesting awareness of current guidelines. The significant differences in PEP-uptake across occupation categories may be due to differential risk perceptions or other underlying factors. This is the first national study to examine PEP-uptake following occupational exposures to HIV. Further research and exploration of these findings are warranted, to understand the role of PEP-uptake behaviour in preventing occupational HIV transmission.

Sexual behaviour and HIV/sexually transmitted infection risk behaviours in the general population of Slovenia, a low HIV prevalence country in central Europe.

OBJECTIVES: To describe sexual and HIV/sexually transmitted infection (STI) risk behaviours in Slovenia. METHODS: A nationally representative cross-sectional survey of the general population aged 18-49 years in 1999-2001 was conducted. The data were collected by face-to-face interviews and anonymous self-administered questionnaires. Statistical methods for complex survey data were used. RESULTS: 849 men and 903 women were interviewed. In the past 5 years, both men and women reported a median of one heterosexual partner (means 3.2, 1.5, respectively), concurrent heterosexual partnerships were reported by 24.4% of men and 8.2% of women, heterosexual sex with non-Slovenian partners by 12.6% of men and 12.2% of women, forced sex by 4.8% of women, paid heterosexual sex by 2.6% of men, sex with another man by 0.6% of men and heterosexual sex with an injecting drug user by 1.2% of men and 1.3% of women. In the past year, 22.7% of men and 9.5% of women reported forming at least one new heterosexual partnership. The mean numbers of episodes of heterosexual sex in the previous 4 weeks were 6.1 for men and 6.0 for women. Consistent and inconsistent condom use was reported more frequently among men reporting multiple female partners and those not married or cohabiting. CONCLUSIONS: Recent patterns of reported sexual behaviour are consistent with a low risk of HIV and STI transmission in Slovenia. The results will inform Slovenian sexual health policies including HIV/STI prevention, and are particularly valuable because population-based data on HIV/STI risk behaviour have not previously been available in low HIV prevalence countries of central Europe.

Sex partner acquisition while overseas: results from a British national probability survey.

BACKGROUND: Over the past 20 years, there has been a huge increase in the number of overseas trips made by UK residents. Although a number of studies have examined the frequency of overseas partner acquisition, they have used convenience samples and thus are not generalisable to the British general population. METHODS: A national probability sample survey was carried out in 1999-2001 of 12,110 men and women aged 16-44 years resident in Britain. Sociodemographic, health-related, travel, sexual behaviour and attitudinal data were collected by computer-assisted interviewing. The main outcomes were the proportion of British residents who reported new sexual partners overseas in the past 5 years, the country of origin of these new sex partners, and the association between reporting a new partner while overseas with a range of demographic, behavioural and attitudinal variables. RESULTS: 13.9% of men and 7.1% of women reported having new sexual partner(s) while overseas in the past 5 years. Among respondents who were aged 16-24 and never married, the proportions were significantly higher (23.0% of men and 17.0% of women). Half of those with new sex partners overseas reported their partner's origin as the UK, and over a third as another European country. In addition to age and marital status, reporting new partners overseas was associated with a higher number of partners, paying for sex (among men), reporting a diagnosis of sexually transmitted infection, and HIV testing. Adjustment for sociodemographic factors attenuated the magnitude of, but did not remove, these associations. CONCLUSIONS: A substantial minority of young, unmarried people form new sexual partnerships abroad, but these are typically with residents from the UK or other European countries. Those who have new partners abroad are likely to have higher-risk sexual lifestyles more generally, and to be at higher risk of sexually transmitted infections. Greater attention should be paid to sexual health promotion for travellers abroad, especially young travellers, emphasising the risks of new sexual relationships with compatriots as well as those from other countries in terms of STI/HIV acquisition and onwards transmission.

A comparison of the population diagnosed with chlamydia in primary care with that diagnosed in sexual health clinics: implications for a national screening programme.

OBJECTIVES: To compare demographic, behavioural and HIV testing characteristics of individuals diagnosed with chlamydia infection in primary care with those in genitourinary medicine clinics, in the absence of a screening programme. The aim was to explore the current and potential contribution of primary care to the control of chlamydia. STUDY DESIGN AND METHODS: We analysed data on individuals who reported one or more chlamydia diagnoses in the past 5 years in a large probability sample survey of the resident, UK general population aged 16-44 years. Estimates were weighted and odds ratios calculated. RESULTS: Women diagnosed in primary care reported fewer sexual partners, and were less likely to have had an HIV test in the past 5 years than their counterparts diagnosed in genitourinary medicine clinics. Age, ethnicity, social class, educational attainment and urbanization of area of residence did not differ between the two groups. Too few men were diagnosed in primary care to allow for such a comparison. CONCLUSIONS: Primary care already diagnoses a large number of women with chlamydia infection, who may perceive themselves as low risk through age or sexual behaviour, yet are likely to comprise a substantial proportion of all infections. Few men are diagnosed in primary care. These groups need to be strategically targeted in the context of a future chlamydia screening programme, which will focus on the screening of younger women at high risk, and in which the role of primary care is still in development.

Who pays for sex? An analysis of the increasing prevalence of female commercial sex contacts among men in Britain.

BACKGROUND: In the United Kingdom the incidence of sexually transmitted infections (STI) and risky sexual behaviours is increasing. The role of commercial sex in this trend is poorly understood. Little is known about the men who pay for sex. We examined the epidemiology of female commercial sex contacts reported by men in 1990 and 2000. METHODS: National probability sample surveys of sexual attitudes and lifestyles (Natsal) of men aged 16-44 resident in Britain in 1990 (n = 6000) and 2000 (n = 4762). RESULTS: The proportion of men who reported paying women for sex in the previous 5 years increased from 2.0% (95% CI 1.6 to 2.5) in 1990 to 4.2% in 2000 (95% CI 3.6 to 4.9). In both surveys, paying for sex was more frequent in men aged between 25 years and 34 years, who were never or previously married, and who lived in London. There was no association with ethnicity, social class, homosexual contact, or injecting drug use. Men who paid for sex were more likely to report 10 or more sexual partners in the previous 5 years; only a minority of their lifetime sexual partners (19.3%) were commercial. They were more likely to meet partners abroad and to report previous STI. Only 15% reported having had an HIV test. CONCLUSION: The proportion of men who reported paying for heterosexual sex has increased, and these men have multiple commercial and non-commercial partners. Their higher rates of STI and low level of HIV testing suggest the need for prevention interventions for clients as well as sex workers.

Factors associated with HIV testing among black Africans in Britain.

OBJECTIVE: To describe the factors associated with HIV testing among heterosexual black Africans aged 16-44 years living in Britain. DESIGN: We analysed data from the second British National Survey of Sexual Attitudes and Lifestyles (Natsal 2000)-a stratified national probability sample survey conducted between 1999-2001. Data from Natsal's main and ethnic minority boost (EMB) samples were analysed. Multivariate analysis was performed using complex survey functions to account for the clustered, stratified, and differential selection probabilities inherent within the survey. RESULTS: A total of 385 (216 women and 169 men) black African respondents were included in the study. 44.0% women and 36.4% men reported ever having had an HIV test. In univariate analysis, HIV testing was associated with being born abroad (OR 3.63), having a new partner(s) from abroad in past 5 years (OR 2.88), and attending a GUM clinic (OR 3.27) among men; and educational attainment (OR 3.50), perception of "not very much" personal risk of HIV (OR 2.75), and attending a GUM clinic (OR 2.91) among women. After adjusting for potential confounders, an increased likelihood of HIV testing was associated with being in the United Kingdom less than 5 years relative to being UK born (adjusted OR 9.49), and ever attending a GUM clinic (adj OR 5.53), for men; and educational attainment (adj OR 4.13), and low perception of HIV risk (adj OR 2.77) for women. CONCLUSIONS: Black Africans appear to have relatively high rates of HIV testing reflecting, at least partially, awareness of risk behaviours and potential exposure to HIV. Nevertheless, there remains substantial potential for health gain and innovative approaches are required to further increase timely HIV testing.

Who reports sexual function problems? Empirical evidence from Britain's 2000 National Survey of Sexual Attitudes and Lifestyles.

OBJECTIVE: To identify sociodemographic, sexual, and health behavioural and attitudinal factors associated with reporting sexual function problems. METHODS: A probability sample survey of 11 161 men and women aged 16-44 years resident in Britain in 2000. Data collected by a combination of computer assisted face to face and self interviewing. Outcomes were self report of a range of sexual function problems, considered as "any problems" (1+ lasting 1+ months in the past year) and "persistent problems" (1+ lasting 6+ months in the past year), and associations with sociodemographic, behavioural, and attitudinal variables. RESULTS: Both "any" and "persistent" sexual function problems were more commonly reported by women than men. A variety of sociodemographic factors were associated with both measures but differed by gender. For example, the adjusted odds ratio (AOR) for reporting any problems for married v single respondents was 0.70 (95% confidence interval (CI) 0.57 to 0.87) v 1.31 (95% CI 1.10 to 1.56) for men and women, respectively. Sexual behaviours significantly associated with reporting sexual function problems included competence at first sex, paying for sex in the past 5 years, number of occasions of sex and masturbation, both in the past 4 weeks. For men (only), reporting STI diagnosis(es) was significantly associated with reporting "any" problems (AOR 2.1, 95% CI 1.4 to 3.2) and "persistent" problems (AOR 2.1, 95% CI 1.1 to 3.9). Both measures were significantly more likely among men and women who reported communication difficulties with their partners, with AORs in excess of 1.9. CONCLUSIONS: Sexual fulfilment is an important part of sexual health. Understanding factors associated with reporting sexual problems, and recognising that such factors maybe partnership specific, is an important step towards improving our understanding of sexual function and thus improving the provision of care and support available.

Conceptualisation, development, and evaluation of a measure of unplanned pregnancy.

STUDY OBJECTIVE: To develop a measure of unplanned pregnancy that is valid, reliable, and appropriate in the context of contemporary demographic trends and social mores and can be used in a variety of situations, including the production of population prevalence estimates. DESIGN: A two stage study design: qualitative (inductive) methods to delineate the construct of pregnancy planning, and quantitative/psychometric methods to establish the means of measurement. SETTING: Eight health service providers (comprising 14 clinics, including antenatal, abortion, and one general practitioner) across London, Edinburgh, Hertfordshire, Salisbury, and Southampton in the UK. PARTICIPANTS: Samples comprised a mixture of pregnant (continuing pregnancy and opting for abortion) and recently pregnant (post-abortion and postnatal) women. At the qualitative stage, 47 women took part in depth interviews (20 of whom were re-interviewed after the birth of their baby). Items were pre-tested with 26 women, and two psychometric field tests were carried out with, respectively, 390 and 651 women. MAIN RESULTS: A six item measure of unplanned pregnancy was produced. Psychometric testing demonstrated the measure's high reliability (Cronbach's alpha = 0.92; test-retest reliability = 0.97) and high face, content, and construct validity. Women's positions in relation to pregnancy planning are represented by the range of scores (0-12). CONCLUSIONS: A psychometric measure of unplanned pregnancy, the development of which was informed by lay views, is now available. The measure is suitable for use with any pregnancy regardless of outcome (that is, birth, abortion, miscarriage) and is highly acceptable to women.

Prevalence of genital Chlamydia trachomatis infection in the general population of Slovenia: serious gaps in control.

OBJECTIVES: One of the objectives of the first national survey of sexual lifestyles, attitudes, and health in Slovenia was to estimate the prevalence of and risk factors for genital Chlamydia trachomatis infection in Slovenian adults aged 18-49 years. METHODS: Data were collected over 1999-2001 from a probability sample of the general population by face to face interviews and anonymous self administered questionnaires. Respondents were invited to provide a first void urine (FVU) specimen for polymerase chain reaction testing for C trachomatis infection. We compared the results to the equivalent British survey. RESULTS: 1447 individuals contributed FVU specimens (82.6% of survey respondents, 55.3% of those eligible). C trachomatis infection was diagnosed in 3.0% of men and 1.6% of women. Prevalence was highest in men and women aged 18-24 years (4.1% for both). Individuals reporting first heterosexual intercourse before the age of 16, unprotected sexual intercourse with at least one heterosexual partner during the preceding year, concurrent heterosexual relationships during the preceding year, and five or more lifetime heterosexual partners had a higher prevalence. The association was statistically significant only for five or more lifetime partners (adjusted OR 3.0; 95% CI 1.3 to 6.9; p = 0.01). CONCLUSIONS: A relatively high prevalence of genital C trachomatis infection among 18-24 year old Slovenians, in the presence of relatively low risk sexual behaviour and low reported incidence rates of chlamydia infection, suggest serious gaps in the diagnosis and treatment of the condition. The results provide support for the introduction of chlamydia screening in Slovenia.
