Sexual and reproductive health in Britain during the first year of the COVID-19 pandemic: cross-sectional population survey (Natsal-COVID-Wave 2) and national surveillance data

OBJECTIVES

To assess sexual behaviour, and sexual and reproductive health (SRH) outcomes, after 1 year of the COVID-19 pandemic in Britain.

METHODS

6658 participants aged 18-59 and resident in Britain completed a cross-sectional web-panel survey (Natsal-COVID-Wave 2, March-April 2021), 1 year after the first lockdown. Natsal-COVID-2 follows the Natsal-COVID-Wave 1 survey (July-August 2020) which captured impacts in the initial months. Quota-based sampling and weighting resulted in a quasi-representative population sample. Data were contextualised with reference to the most recent probability sample population data (Natsal-3; collected 2010-12; 15 162 participants aged 16-74) and national surveillance data on recorded sexually transmitted infection (STI) testing, conceptions, and abortions in England/Wales (2010-2020). The main outcomes were: sexual behaviour; SRH service use; pregnancy, abortion and fertility management; sexual dissatisfaction, distress and difficulties.

RESULTS

In the year from the first lockdown, over two-thirds of participants reported one or more sexual partners (women 71.8%; men 69.9%), while fewer than 20.0% reported a new partner (women 10.4%; men 16.8%). Median occasions of sex per month was two. Compared with 2010-12 (Natsal-3), we found less sexual risk behaviour (lower reporting of multiple partners, new partners, and new condomless partners), including among younger participants and those reporting same-sex behaviour. One in 10 women reported a pregnancy; pregnancies were fewer than in 2010-12 and less likely to be scored as unplanned. 19.3% of women and 22.8% of men were distressed or worried about their sex life, significantly more than in 2010-12. Compared with surveillance trends from 2010 to 2019, we found lower than expected use of STI-related services and HIV testing, lower levels of chlamydia testing, and fewer conceptions and abortions.

CONCLUSIONS

Our findings are consistent with significant changes in sexual behaviour, SRH, and service uptake in the year following the first lockdown in Britain. These data are foundational to SRH recovery and policy planning.

Douching cessation and molecular bacterial vaginosis: a reanalysis of archived specimens

OBJECTIVES

Observational studies demonstrate an association between vaginal douching and bacterial vaginosis (BV) characterised by Gram stain. We sought to describe the effect of a douching cessation intervention on the composition and structure of the vaginal microbiota and molecular-BV, a state defined by low levels of Lactobacillus spp evaluated by molecular tools.

METHODS

33 women self-collected mid-vaginal swabs twice weekly (982 samples) during a douching observation phase (4 weeks) followed by a douching cessation phase (12 weeks) in a 2005 single crossover pilot study conducted in Baltimore, Maryland. Vaginal microbiota were characterised by 16S rRNA gene amplicon sequencing (V3-V4) and clustered into community state types (CSTs). Conditional logistic regression modelling allowed each participant to serve as their own control. Wilcoxon signed-rank tests were used to evaluate changes in microbiota between phases. Broad-range qPCR assays provided estimates of bacterial absolute abundance per swab in a subsample of seven participants before and after douching. A piecewise linear mixed effects model was used to assess rates of change in bacterial absolute abundance before and after douching.

RESULTS

There was no statistically significant change in the odds of molecular-BV versus Lactobacillus-dominated CSTs comparing the douching cessation interval to douching observation (adjusted OR 1.77, 95% CI 0.89 to 3.55). Removal of L. iners-dominated CST III from the outcome did not affect the results. There were no significant changes in the relative abundance of four Lactobacillus spp and no meaningful changes in other taxa investigated. There was no significant change in bacterial absolute abundance between a participant's sample collected 3 days prior to and following douching (p=0.46).

CONCLUSIONS

In this pilot study, douching cessation was not associated with major changes in vaginal microbiota. Douching cessation alone may not durably shift the vaginal microbiota and additional interventions may be needed to restore optimal vaginal microbiota among those who douche.

Gender-inclusive writing for epidemiological research on pregnancy

People who have a uterus but are not cisgender women may carry pregnancies. Unfortunately, to date, academic language surrounding pregnancy remains largely (cis) woman-centric. The exclusion of gender-diverse people in the language of pregnancy research in English is pervasive. In reviewing a random sample of 500 recent articles on pregnancy or pregnant populations across health research fields, we found that only 1.2% of articles used gender-inclusive language (none of them in epidemiology), while the remaining 98.8% used (cis) woman-centric language. First and foremost, recent recommendations highlight the need to include trans, non-binary and gender-diverse people in study design. Meanwhile, there remains a lack of awareness that all research on pregnancy can contribute to inclusiveness, including in dissemination and retroactive description. We explain how the ubiquitous use of (cis) woman-centric language in pregnancy-related research contributes to (1) the erasure of gender diversity; (2) inaccurate scientific communication and (3) negative societal impacts, such as perpetuating the use of exclusionary language by students, practitioners, clinicians, policy-makers and the media. We follow with recommendations for gender-inclusive language in every section (ie, introductions, methods, results, discussions) of epidemiological articles on pregnant populations. The erasure of gender-diverse people in the rhetoric of research about pregnant people can be addressed immediately, including in the dissemination of results from ongoing studies that did not take gender diversity into consideration. This makes gender-inclusive language a crucial first step towards the inclusion of gender-diverse people in epidemiological research on pregnant people and other health research more globally.

Sexuality education for young people in Germany.Results of the 'Youth Sexuality' representative repeat survey

The Federal Centre for Health Education (BZgA) has been conducting the 'Youth Sexuality' representative survey on a regular basis since 1980. This continuous monitoring generates insights into the sexual and reproductive health of young people in Germany and constitutes an important basis for evidence-based health communication. A total of N=6,032 young people between the ages of 14 and 25 participated in a combination of oral and written interviews (Computer Assisted Personal Interviews (CAPI)). As primary sources of knowledge for, adolescents state that they obtain information through school lessons (69%), personal discussions (68%), and the Internet (59%). In addition to these sources, professional gynaecological counselling and sexuality education at home are also important sources of information. To what extent trusted contact persons are available in the family depends heavily on the adolescents' sociocultural backgrounds. Providing information and disseminating knowledge to young people in the field of sexual and reproductive health is organised intersectorally in Germany. In this way, it is possible to also reach those who do not have any contact persons at their disposal in their direct family. Maintaining and strengthening the current commitment in promoting sexual health is of key importance, as only this will ensure the next generation's sexual and reproductive health, and provide an evidence-based counterbalance to anecdotal information, especially in the digital domain.

Provision of the progestogen-only pill by community pharmacies as bridging contraception for women receiving emergency contraception: the Bridge-it RCT

INTRODUCTION

Unless women start effective contraception after using emergency contraception, they remain at risk of unintended pregnancy. Most women in the UK obtain emergency contraception from community pharmacies that are unable to provide ongoing contraception (apart from barrier methods which have high failure rates). This means that women need an appointment with a general practitioner or at a sexual and reproductive health clinic. We conducted a pragmatic cluster randomised cohort crossover trial to determine whether or not pharmacist provision of a bridging supply of a progestogen-only pill plus the invitation to attend a sexual and reproductive health clinic resulted in increased subsequent use of effective contraception (hormonal or intrauterine).

METHODS

Twenty-nine pharmacies in three UK cities recruited women receiving emergency contraception (levonorgestrel). In the intervention, women received a 3-month supply of the progestogen-only pill (75 µg of desogestrel) plus a card that provided rapid access to a local sexual and reproductive health clinic. In the control arm, pharmacists advised women to attend their usual contraceptive provider. The primary outcome was reported use of an effective contraception (hormonal and intrauterine methods) at 4 months. Process evaluation was also conducted to inform any future implementation.

RESULTS

The study took place December 2017 and June 2019 and recruited 636 women to the intervention (n = 316) and control groups (n = 320). There were no statistically significant differences in demographic characteristics between the groups. Four-month follow-up data were available for 406 participants: 63% (198/315) of the control group and 65% (208/318) of the intervention group. The proportion of participants reporting use of effective contraception was 20.1% greater (95% confidence interval 5.2% to 35.0%) in the intervention group (58.4%, 95% confidence interval 48.6% to 68.2%) than in the control group (40.5%, 95% confidence interval 29.7% to 51.3%) (adjusted for recruitment period, treatment arm and centre; p = 0.011). The proportion of women using effective contraception remained statistically significantly larger, when adjusted for age, current sexual relationship and history of past use of effective contraception, and was robust to the missing data. There were no serious adverse events.

CONCLUSION

Provision of a bridging supply of the progestogen-only pill with emergency contraception from a pharmacist and the invitation to a sexual and reproductive health clinic resulted in a significant increase in self-reported subsequent use of effective contraception. This simple intervention has the potential to prevent more unintended pregnancies for women after emergency contraception.

Impact of expedited partner therapy (EPT) implementation on chlamydia incidence in the USA

OBJECTIVES

The diagnosis and treatment of Chlamydia trachomatis infection is important in preventing persistent or recurrent infection. Expedited partner therapy (EPT) is the favoured and supported method for STI treatment of the Centers for Disease Control and Prevention when the provider cannot be assured that all recent sexual partner(s) will seek therapy. EPT is legally permissible in 38 states and is endorsed by healthcare organisations to decrease the rates of chlamydia and gonorrhoea infection. Our study investigated the impact of EPT legal status (permissible, potentially allowable or prohibited) on C. trachomatis infection rates for each state.

METHODS

Our ecological study modelled the number of reported chlamydia cases from 2000 to 2013 as a function of year, legal status and the interaction between year and legality. We used a negative binomial regression model that included state fixed effects (including the District of Columbia) to account for both the repeated measures per state and state-specific characteristics that could not be measured for inclusion in this study. The lagged number of C. trachomatis cases was included as a covariate and each state's total population for a given year was included in the model as an exposure parameter. States were designated Y (EPT permissible), N (EPT prohibited) and M (EPT potentially allowable), and the legal status of each state could vary over time.

RESULTS

Each legal category saw an increase in the incidence rate of C. trachomatis infection, but on average, the incidence rate for states with prohibitive EPT legislation grew significantly faster over time compared with the rate for the states where EPT was permissible. The average increase in predicted incidence rates per year for states with Y, N and M legal status were 14.1 (95% CI (12.0 to 16.2)), 17.5 (95% CI (15.9 to 19.2)) and 16.8 (95% CI (15.0 to 18.6)) cases per 100 000 persons per year, respectively, when controlling for state-specific effects.

CONCLUSIONS

Our model suggests that a lack of EPT legislation is associated with an increase in STI rates. States with potentially allowable EPT legislation as of 2013 (n=8) should consider permitting EPT as a component of a multipronged strategy for treatment of sexual partners to prevent C. trachomatis infection.

Comparing 3-month recall to daily reporting of sexual behaviours

OBJECTIVES

This study aimed to examine discrepancies between self-report methods and methodological issues related to sexual risk taking. We examined sexual behaviour assessed via 3-month electronic recall and by daily electronic reporting among a large cohort of patients attending STI clinics.

METHODS

STI clinic attenders (N= 628) aged 15 to 60 years reported on demographic information (at baseline), penile-vaginal sex acts, condom-unprotected penile-vaginal sex and STI history using 3-month recall and daily reports. Additionally, interviewer-participant match related to race and gender, as well as study site were considered as covariates.

RESULTS

Concordance between recall and daily reports on penile-vaginal sex was moderately strong (Spearman's r (rs)=0.62; p<0.001). Comparison for reports for condom-unprotected penile-vaginal sex resulted in a correlation coefficient of 0.61 (p<0.001), also indicating moderately strong agreement between the two methods. Two generalised logit models were conducted to explain lack of strong concordance in penile-vaginal sex acts and condom-unprotected penile-vaginal sex. The odds of a female reporting higher frequency of sex in daily reports compared with recall were more than two times that of a male. Every five person increase in the number of lifetime sexual partners was associated with five times the odds of a discrepancy in reporting methods. Age was also significantly associated with unequal daily versus recall sex frequency reporting.

CONCLUSIONS

Shifting focus to methodological considerations of technological reports can help ensure better investment of resources into sexual health research due to greater understanding of the methodological properties of data collection methods.

Prevalence of reproductive tract infections and the predictive value of girls' symptom-based reporting: findings from a cross-sectional survey in rural western Kenya

Objectives

Reproductive tract infections (RTIs), including sexually acquired, among adolescent girls is a public health concern, but few studies have measured prevalence in low-middle-income countries. The objective of this study was to examine prevalence in rural schoolgirls in Kenya against their reported symptoms.

Methods

In 2013, a survey was conducted in 542 adolescent schoolgirls aged 14–17 years who were enrolled in a menstrual feasibility study. Vaginal self-swabbing was conducted after girls were interviewed face-to-face by trained nurses on symptoms. The prevalence of girls with symptoms and laboratory-confirmed infections, and the sensitivity, specificity, positive and negative predictive values of symptoms compared with laboratory results, were calculated.

Results

Of 515 girls agreeing to self-swab, 510 answered symptom questions. A quarter (24%) reported one or more symptoms; most commonly vaginal discharge (11%), pain (9%) or itching (4%). Laboratory tests confirmed 28% of girls had one or more RTI. Prevalence rose with age; among girls aged 16–17 years, 33% had infections. Bacterial vaginosis was the most common (18%), followed by Candida albicans (9%), Chlamydia trachomatis (3%), Trichomonas vaginalis (3%) and Neisseria gonorrhoeae (1%). Reported symptoms had a low sensitivity and positive predictive value. Three-quarters of girls with bacterial vaginosis and C. albicans, and 50% with T. vaginalis were asymptomatic.

Conclusions

There is a high prevalence of adolescent schoolgirls with RTI in rural Kenya. Public efforts are required to identify and treat infections among girls to reduce longer-term sequelae but poor reliability of symptom reporting minimises utility of symptom-based diagnosis in this population.

Reaching the poor with health interventions: programme-incidence analysis of seven randomised trials of women's groups to reduce newborn mortality in Asia and Africa

BACKGROUND

Efforts to end preventable newborn deaths will fail if the poor are not reached with effective interventions. To understand what works to reach vulnerable groups, we describe and explain the uptake of a highly effective community-based newborn health intervention across social strata in Asia and Africa.

METHODS

We conducted a secondary analysis of seven randomised trials of participatory women's groups to reduce newborn mortality in India, Bangladesh, Nepal and Malawi. We analysed data on 70,574 pregnancies. Socioeconomic and sociodemographic differences in group attendance were tested using logistic regression. Qualitative data were collected at each trial site (225 focus groups, 20 interviews) to understand our results.

RESULTS

Socioeconomic differences in women's group attendance were small, except for occasional lower attendance by elites. Sociodemographic differences were large, with lower attendance by young primigravid women in African as well as in South Asian sites. The intervention was considered relevant and interesting to all socioeconomic groups. Local facilitators ensured inclusion of poorer women. Embarrassment and family constraints on movement outside the home restricted attendance among primigravid women. Reproductive health discussions were perceived as inappropriate for them.

CONCLUSIONS

Community-based women's groups can help to reach every newborn with effective interventions. Equitable intervention uptake is enhanced when facilitators actively encourage all women to attend, organise meetings at the participants' convenience and use approaches that are easily understandable for the less educated. Focused efforts to include primigravid women are necessary, working with families and communities to decrease social taboos.

Declines in stillbirth and neonatal mortality rates in Europe between 2004 and 2010: results from the Euro-Peristat project

Background

Stillbirth and neonatal mortality rates declined in Europe between 2004 and 2010. We hypothesised that declines might be greater for countries with higher mortality in 2004 and disproportionally affect very preterm infants at highest risk.

Methods

Data about live births, stillbirths and neonatal deaths by gestational age (GA) were collected using a common protocol by the Euro-Peristat project in 2004 and 2010. We analysed stillbirths at ≥28 weeks GA in 22 countries and live births ≥24 weeks GA for neonatal mortality in 18 countries. Per cent changes over time were assessed by calculating risk ratios (RR) for stillbirth, neonatal mortality and preterm birth rates in 2010 vs 2004. We used meta-analysis techniques to derive pooled RR using random-effects models overall, by GA subgroups and by mortality level in 2004.

Results

Between 2004 and 2010, stillbirths declined by 17% (95% CI 10% to 23%), with a range from 1% to 39% by country. Neonatal mortality declined by 29% (95% CI 23% to 35%) with a range from 9% to 67%. Preterm birth rates did not change: 0% (95% CI −3% to 3%). Mortality declines were of a similar magnitude at all GA; mortality levels in 2004 were not associated with RRs.

Conclusions

Stillbirths and neonatal deaths declined at all gestational ages in countries with both high and low levels of mortality in 2004. These results raise questions about how low-mortality countries achieve continued declines and highlight the importance of improving care across the GA spectrum.

Does integration of HIV and SRH services achieve economies of scale and scope in practice? A cost function analysis of the Integra Initiative

OBJECTIVE

Policy-makers have long argued about the potential efficiency gains and cost savings from integrating HIV and sexual reproductive health (SRH) services, particularly in resource-constrained settings with generalised HIV epidemics. However, until now, little empirical evidence exists on whether the hypothesised efficiency gains associated with such integration can be achieved in practice.

METHODS

We estimated a quadratic cost function using data obtained from 40 health facilities, over a 2-year-period, in Kenya and Swaziland. The quadratic specification enables us to determine the existence of economies of scale and scope.

FINDINGS

The empirical results reveal that at the current output levels, only HIV counselling and testing services are characterised by service-specific economies of scale. However, no overall economies of scale exist as all outputs are increased. The results also indicate cost complementarities between cervical cancer screening and HIV care; post-natal care and HIV care and family planning and sexually transmitted infection treatment combinations only.

CONCLUSIONS

The results from this analysis reveal that contrary to expectation, efficiency gains from the integration of HIV and SRH services, if any, are likely to be modest. Efficiency gains are likely to be most achievable in settings that are currently delivering HIV and SRH services at a low scale with high levels of fixed costs. The presence of cost complementarities for only three service combinations implies that careful consideration of setting-specific clinical practices and the extent to which they can be combined should be made when deciding which services to integrate.

Prevalence and risk factors for Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis infection in pregnant women in Papua New Guinea

OBJECTIVE

To determine the prevalence of, and risk factors associated with, Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis infection in pregnant women in Madang, Papua New Guinea (PNG).

METHODS

A cross-sectional survey was conducted among 400 pregnant women presenting to antenatal clinics. Sociodemographic and behavioural data were collected and real-time PCR diagnostic methods were used to detect the presence of chlamydia, gonorrhoea and trichomonas in self-collected vaginal swabs. The relationships between symptoms, sociodemographic and behavioural factors and infection were assessed.

RESULTS

The prevalence of C. trachomatis was 11.1%, N. gonorrhoeae was 9.7% and T. vaginalis was 21.3%. One-third of women (33.7%) had at least one infection. The most common symptom was abdominal pain (48.0%), but only abnormal vaginal discharge was consistently associated with infection (p<0.001). Women diagnosed with vaginal discharge syndrome were more likely to have at least one treatable infection (50.0% (47/94)  vs 26.8% (68/254), p<0.001), yet 59.1% of women with infection would have been missed by the current clinically-based syndromic diagnosis. Risk factors included having a partner at perceived risk of infection, maternal extramarital intercourse, early sexual debut, lack of formal education, urban residence and smoking. 78.8% of women reported never using condoms.

CONCLUSIONS

The prevalences of T. vaginalis, C. trachomatis and N. gonorrhoeae were high among pregnant women in coastal PNG. The poor performance of clinically based syndromic diagnosis suggests that alternative strategies are urgently required to improve detection and reduce the burden of sexually transmitted infections and their associated adverse pregnancy outcomes in this population.

Evaluating the social determinants of teenage pregnancy: a temporal analysis using a UK obstetric database from 1950 to 2010

BACKGROUND

Teenage pregnancy is a known social problem which has been previously described using a number of deprivation measures. This study aimed to explore the temporal patterns of teenage pregnancy in Aberdeen, Scotland and to assess the discriminating ability of three measures of socioeconomic status.

METHODS

This was a population-based study from 1950 to 2010, using data from the Aberdeen Maternity Neonatal Databank (AMND). The main outcome variable was conceptions occurring in women aged less than 20 years. This study used two area-based measures, the Scottish Index of Multiple Deprivation (SIMD) and the Carstairs index, and one individual-based measure the Social Class based on Occupation (SCO). These measures were compared for their association with teenage conceptions using logistic regression models. The models were used to determine receiver operating characteristic (ROC) curves showing the discriminating ability of the measures.

RESULTS

There was an overall decline in teenage conceptions over the 60-year period, but an increase in the rate ratio for deprived areas. All the measures of socioeconomic status were highly associated with teenage pregnancy. The adjusted OR of SIMD and teenage conception was 5.72 (95% CI 4.62 to 7.09), which compared the most deprived decile with the least deprived decile. The use of ROC curves showed that socioeconomic measures performed better than chance at determining teenage conceptions (χ(2)=21.67, p≤0.0001). They further showed that the SIMD had the largest area under the curve (AUC) with a value of 0.81 (95% CI 0.80 to 0.82), followed by the Carstairs index with an AUC of 0.80 (95% CI 0.78 to 0.80), then by SCO with an AUC of 0.79 (95% CI 0.78 to 0.80).

CONCLUSIONS

Despite a slight decline in teenage pregnancies over the past decades, there is still an evident association between deprivation and teenage pregnancy. This study shows that all the measures of socioeconomic status were highly associated with teenage pregnancy, with the SIMD having the greatest discriminatory effect.
