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.


INTRODUCTION
Sexual and reproductive health (SRH) is vital for population well-being. 1 Services like detection and management of sexually transmitted infections (STIs), fertility management and pregnancyrelated care are continually required, even during lockdowns. 2 3In Britain, national COVID-19 lockdowns began on 23 March 2020 and on 5 January 2021, each lasting approximately 4 months, interspersed by fluctuating restrictions.SRH services in Britain were severely disrupted.Although positive innovations occurred-including telemedicine

WHAT IS ALREADY KNOWN ON THIS TOPIC
⇒ Early in the pandemic, studies suggested a reduction in sexual risk behaviour, a decline in sexual frequency and desire, and an increase in virtual activities for some.⇒ The pandemic also significantly affected access to SRH services, as well as to preventive and reproductive technologies.

WHAT THIS STUDY ADDS
⇒ This study shows that reductions in sexual risk behaviour and service uptake detected early in the pandemic were still evident 1 year following the first COVID-19 lockdown in Britain.⇒ This study also suggests that after 1 year there were fewer reported pregnancies, fewer reported abortions, and increased sexual dissatisfaction and distress, compared with what might be expected based on previous survey and surveillance data.

HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY
⇒ These data suggest that recovery should focus on restoring STI prevention behaviours, provision of free or low-cost condoms, catchingup on service-provision backlogs, counselling for sexual difficulties, and sex education for young people who missed out during the pandemic.

Original research
and self-administered at-home mifepristone/misoprostol for early abortion care-the overall picture suggested reduced or suspended services. 2 4 5Evidence indicated that people selfcensured their sexual health needs and experienced barriers to service access 3 ; in the 4 months after the first lockdown began, 9.7% of people in Britain reported at least one failed attempt to access an SRH service. 2 Surveillance data showed a large reduction in sexual health clinic attendance and STI/HIV testing in April-May 2020, which was only partially offset by increased online testing.Clinic attendance and STI/HIV testing increased through the second half of 2020 but did not reach pre-pandemic levels. 6Prescribing of HIV pre-exposure prophylaxis (PrEP) and long-acting reversible contraception (LARC) also fell and only partially recovered. 7uring the pandemic's early months, changes in sexual behaviour were primarily due to reduced opportunities to have sex for people not cohabiting with a partner.While many people reported no changes, most studies found that frequency of partnered sex declined overall. 8Young people and those not in cohabiting relationships were more likely to report decreased sexual frequency and satisfaction and increased non-partnered activities like masturbation and viewing pornography. 9 10These groups and men who have sex with men (MSM) reported fewer sexual partners, 11 and risk reductions in MSM were commonly found across studies. 8In steady relationships, people commonly reported improved relationship quality but diminished sex life quality. 12Studies variously reported no change, improvement, and declines in sexual function, with declines more pronounced for women than men. 8However, evidence on population sexual behaviour and SRH is weak; most initial studies used convenience sampling and lacked a baseline, preventing assessment of the pandemic's impact.The timeframe for these studies was also too short to reliably detect changes in SRH outcomes, such as pregnancy and abortion.Thus, early reviews have called for longer-term evidence. 8he Natsal COVID-19 study was conducted in two waves.Natsal-COVID-1 (first wave) was conducted 4 months after the first UK lockdown (July-August 2020) and provided population-level evidence on behaviour and service use in the initial months. 2 3 9 12Here we present data from the second wave (Natsal-COVID-2; March-April 2021), which was designed to track behaviour over a longer period and provide 1 year estimates of SRH outcomes.We examined patterns of sexual behaviour, SRH service use, pregnancy, abortion and fertility management, and sexual function and sex life quality in the year following the first lockdown.

Study design
The second wave survey (Natsal-COVID-2) was undertaken between 27 March and 26 April 2021, approximately 1 year after the first UK lockdown, using similar methods to the first survey (undertaken between 29 July and 10 August, 4 months after first lockdown).Detailed methods are presented elsewhere. 13 14Data were collected using a 13 min online questionnaire (available at https://www.natsal.ac.uk/natsal-covid-study) through a webpanel survey administered by Ipsos MORI.Participants provided informed consent via an online form before starting the survey.

Participants and procedures
The target core sample was 6000 people aged 18-59 years, with an additional boost of 500 people aged 18-29 years.To achieve a quasi-representative sample of the British population, we used quotas of age, gender, region, and social grade.Data were subsequently weighted to match the expected population distributions for the quota characteristics and sexual identity.The sample was drawn first from participants taking part in the first survey and agreeing to re-contact (n=5535), of whom 2098 completed the second survey (longitudinal analyses will be reported elsewhere).No quotas were set for this group.To reach the target sample, new participants were sampled until the quotas were reached.We obtained ethical approval from the University of Glasgow (20019174) and the London School of Hygiene and Tropical Medicine (LSHTM) (22565).Table 1 defines key terms describing participants.

Comparison with pre-COVID population data and surveillance data trends
There is no available pre-pandemic population baseline on SRH as such data are not routinely collected.To assess the extent to which observed outcomes might be due to the pandemic we compared our findings with data from Natsal-3, the most recent national survey (data collected 2010-12; 15 162 participants aged 16-74)). 15 16Natsal-3 used a multistage, clustered, and stratified probability sample design conducting face-to-face interviews in participants' homes.Natsal-1 (1990) and Natsal-2 (2000) used broadly similar methods (figure 1).We also examined trends in national surveillance data during the decade between Natsal-3 (2010-12) and 2019 to assess how secular trends might have contributed to measured differences between the surveys, and we present data points for 2020 where available (see data sources in table 2).Surveillance data observations from 2010 to 2019 represent an 'unexposed population'.Data points from 2020 include events during the first pandemic year and possible anticipatory effects in pre-lockdown months; thus 2020 data points cannot be used to estimate reliably covid-exposed or covid-unexposed rates and are not included in trend analysis.Surveillance data do not capture underlying sexual behaviours or unmet need in the general population 17 and may themselves be subject to impacts of the pandemic on data collection, but they indicate year-on-year trends not captured in survey data, and are not subject to selection and reporting bias.

Statistical analyses
Outcome variables are described in online supplemental box 3. Data are presented for participants aged 18-59 years, with exceptions stated.We used Stata's (version 16.1) complex survey functions to incorporate weighting and stratification.Figure 2 was constructed in R (v4.2.1) using 'ggplot2'. 18 19We present descriptive statistics for reported outcome variables by age group, gender, and same-sex behaviour.We tested differences in selected risk behaviours by gender and same sex behaviour and calculated age-adjusted odds ratios (aOR) using logistic regression.Where available for both surveys, we report aORs for outcome variables in Natsal-COVID-2 vs Natsal-3.Item nonresponse in Natsal-COVID-2 was typically 1-4% for the variables in this analysis.For surveillance data, we plotted annual rates, inspected for pre-covid linear trends (2010-19) and fitted linear models.

Patterns of sexual behaviour
Among sexually experienced participants aged 18-59 years, 71.8% of women and 69.9% of men reported at least one sexual partner in the year starting from the first lockdown; 35.5% of women and 37.0% of men reported having sex at least once per week in the preceding 4 weeks; this proportion declined with age among both women (from 41.3% (age 18-24) to 24.3% (age 45-59) and men (from 48.2% to 26.0%) (table 3).The median reported occasions of sex per month was two, compared with medians of three in 2010 (Natsal-3), four in 2000 (Natsal-2), and five in 1990 (Natsal-1) (figure 1).There were significant gender differences in reported sexual behaviours associated with elevated STI risk.Fewer women (5.4%) than men (9.6%) reported two or more partners in the past year (aOR 0.51, 95% CI 0.41 to 0.63).Women were also less likely to report one or more new sexual partners (10.4% vs 16.8%; aOR 0.51, 95% CI 0.43 to 0.61) and one or more new condomless partners (6.4% vs 11.5%; aOR 0.48, 95% CI 0.39 to 0.59) in the past year (table 3).Among women and men, reporting of risk behaviours declined with age.Women who reported sex with women (WSW) and men who reported sex with men (MSM) were more likely to report STI risk behaviours than all women and all men, respectively (excepting condomless      *'All' comprises sexually experienced participants aged 18-59 years, including women who have sex with women (WSW) and men who have sex with men (MSM).†WSW and MSM were defined as women and men, respectively, who reported a previous same-sex experience in the past 5 years.‡Age-adjusted odds ratios (aOR) compare 1 year prevalence rates in Natsal-COVID-2 vs Natsal-3.
For each aOR, '0 partners' is the reference group for a dichotomous outcome variable.As such, the aOR for 'one partner' represents odds of having one or more partners in the past year in Natsal-COVID-2 vs Natsal-3.Denominators for number of partners are shown; other denominators were of similar magnitude.§Natsal-3 comparison not available due to lack of variable in Natsal-3 dataset.

sex for WSW).Reporting these risk behaviours decreased with age.
Compared with 10 years previously (Natsal-3), women and men in Natsal-COVID-2 were less likely to report two or more sexual partners in the past year (women: 5.4% vs 13.5%, aOR 0.30, 95% CI 0.25 to 0.36; men: 9.6% vs 19.4%, aOR 0.37, 95% CI 0.31 to 0.43).Similar differences between surveys were observed for numbers of reported new sexual partners for women and men, and for WSW and MSM.

SRH service use
To understand uptake of sexual health services during the pandemic, sexually experienced participants aged 18-44 years reported their use of STI-related services, chlamydia testing, HIV testing, and cervical cancer screening (table 4).
HIV testing in the past year was reported by 8.6% of women, 6.5% of men, and 29.1% of MSM in Natsal-COVID-2 (sexually experienced participants).These proportions paralleled Natsal-3 for men and MSM, but women in Natsal-COVID-2 were less likely than women in Natsal-3 to report an HIV test in the past year (aOR 0.80, 95% CI 0.66 to 0.99) (table 4).
Among eligible participants aged 25-59 years, 10.3% reported cervical cancer screening in the past year (approximately 18% would be expected to report this based on uptake in a comparable 1 year period before the pandemic (see calculation, table 2). 20There was a strong association with age; those aged 45-59 years were less likely to report cervical cancer screening than those aged 25-29 years.
Surveillance data (figure 2) for use of STI services and HIV testing indicate linear increasing trends between 2010 and 2019, suggesting that 2020 rates would have been higher than 2010 rates if there had been no pandemic.Chlamydia testing rates appear stable in surveillance data, suggesting that 2020 rates might also have been stable without the pandemic.Against this backdrop, the comparison of survey data between Natsal-3 and Natsal-COVID-2 surveys and the 2020 surveillance data points are consistent in suggesting that the pandemic contributed to lower-than-expected rates for these outcomes Pregnancy, abortion and fertility management Among sexually experienced participants described as female at birth and aged 18-44 years, 10.6% reported that they stopped using or switched their contraceptive method in the past year due to the pandemic; this was highest in those aged 18-24 years (16.4%)(table 5).Compared with Natsal-3, fewer participants reported a pregnancy in the past year (10.6% vs 14.6%; aOR 0.56, 95% CI 0.47 to 0.67).Pregnancies in Natsal-COVID-2 were less likely to be scored as unplanned (6.2% vs 18.3%; aOR 0.33, 95% CI 0.18 to 0.59).The proportion of participants who reported abortion in the past year was lower in Natsal-COVID-2 than in Natsal-3 (0.8% vs 2.3%; aOR 0.34, 95% CI 0.18 to 0.63).
Surveillance data (figure 2) show a shallow decreasing trend in conceptions between 2010 to 2019 and an increasing trend in abortions, which compare with substantial falls in the estimates for both outcomes between Natsal-3 and Natsal-COVID-2.The surveillance data point for abortions in 2020-which includes pre-lockdown abortions-is in line with baseline trends.

Sexual dissatisfaction, distress and difficulties
Sexual dissatisfaction and distress about sex were common experiences in the first year of the pandemic.Dissatisfaction increased with age (from 19.7% (age 18-24) to 28.6% (age 45-59) among women, and from 17.0% to 41.5% among men) (table 6).In contrast, levels of distress were similar across age groups among women, and decreased among men (from 26.5% to 18.5%).Women were less likely than men to report dissatisfaction and distress (26.8% vs 32.2%; aOR 0.77, 95% CI 0.68 to 0.87 for dissatisfaction, and 19.3% vs 22.8%; aOR 0.81, 95% CI 0.71 to 0.93 for distress).There was no significant variation in these outcomes by reported same-sex behaviour, except that MSM were more likely to report distress than all men (37.7% vs 22.8%; aOR 1.95, 95% 1.35 to 2.81).
Around one in 10 sexually experienced participants reported sexual difficulties, and a similar proportion reported avoiding sex because of difficulties in the first year of the pandemic (table 6).For both outcomes, we observed decreases with age among men (from 20.0% (age 18-24) to 6.1% (age 45-59) for sexual difficulties; from 22.0% to 5.2% for avoiding sex), but not women.Both were more commonly experienced by MSM than all men (sexual difficulties: 29.5%, aOR 3.42, 95% CI 2.26 to 5.20; avoiding sex: 26.3%, aOR 3.15, 95% CI 2.01 to 4.93).There were no significant differences between WSW and all women (data not shown).
Participants compared their sex life during the first year of the COVID-19 pandemic with the previous year (table 6).Approximately one quarter (women: 25.5%, 95% CI 23.9% to 27.2%; men: 26.3%, 95% CI 24.6% to 28.2%) perceived their sex life during COVID-19 pandemic to be worse than the previous year; this increased with age for men (from 18.7% (age 18-24) to 27.9% (age 45-59)) but not women.There were no significant differences by gender or reported same-sex experience.

DISCUSSION
Fewer than 20% of participants reported a new partner during the first year of the pandemic, compared with more than 25% in Natsal-3 (2010-12).We observed much lower reported chlamydia testing in Natsal-COVID-2 than Natsal-

Original research
Sexual health service access and HIV testing were similar between the surveys, contrasting with rising trends suggested by surveillance data.Just under 10% of Natsal-COVID-2 participants described as female at birth reported that they switched or stopped using their contraception methods in the past year due to the pandemic.Pregnancies and abortions in the first year of the pandemic were lower than estimates from a decade earlier (Natsal-3).Surveillance data showing stable conception and rising abortion trends in the prior decade suggest that the pandemic contributed to reductions observed between the surveys.Distress and dissatisfaction with one's sex life were common during the pandemic and at a significantly higher level than 10 years previously.
To our knowledge, Natsal-COVID-2 is the most comprehensive general population study of SRH during the COVID-19 pandemic. 8The study was not a probability sample but used quota-based sampling and weighting to improve generalisability.However, specific estimates should be interpreted with caution given likely selection and response biases.In particular, webbased surveys exclude people without digital access, who are more likely to be in lower social grades. 21ithout a baseline, the best available comparison data source was the Natsal-3 survey, with two important caveats.First, the methodology was different.Natsal-3 was a householdbased interviewer-led CAPI/CASI (computer-assisted personal interviewing/computer-assisted self-interviewing) probability sample, whereas Natsal-COVID-2 was a web-panel survey.Differential selection probabilities between surveys and other biases are only partially corrected by weighting. 22 23Second, Natsal-3 data were collected 10 years ago (2010-2012) and sexual behaviour, sexual mores and service provision have all undergone period changes, which affect comparisons.Methodological differences and secular change may partially account for the observed differences.
Frequency of sex has been steadily declining since Natsal-1 in 1990/91, and the decline observed in the present study may reflect a secular trend unrelated to the pandemic.Although we lack interim data for sexual behaviours, the rate of diagnosis for most STIs provides a proxy and has increased year-on-year in Britain during this period. 24Thus, but for the pandemic, we might have reasonably expected similar or increased levels of sexual risk behaviour compared with Natsal-3.The lower levels observed in our study were most pronounced in younger participants and men reporting same-sex behaviour-key populations with high rates of STIs.The data suggest a fall in the number of sexual partners, number of new partners and condomless sex with a new partner.This is consistent with what we know from studies earlier in the pandemic, including Natsal-COVID-1.Most of these earlier studies focused on MSM, finding a reduction in the number of casual partners and unprotected anal intercourse. 8These findings are intuitively plausible because lockdowns restricted physical and social interactions. 9 11verall differences observed between Natsal-COVID-2 and Natsal-3 in chlamydia testing were also found in younger participants, who are targeted by the National Chlamydia Screening Programme (which, until June 2021, targeted opportunistic chlamydia testing to sexually active people under 25 years), and in those reporting at least one new partner in the past year, who are recommended to test by the British Association for Sexual Health and HIV (BASHH) guidelines.By contrast to the survey comparisons, surveillance data showed stable chlamydia testing and rising sexual health service attendance and HIV testing in the years preceding the pandemic.Taken together, we infer that the pandemic's effect has been a significant drop in uptake of these services-a finding consistent with a large international study (I-SHARE). 25This occurred despite rapid responses by sexual health services (eg, online and telephone alternatives to face-to-face consultations).
Stopping or switching contraceptive methods is associated with a higher risk of unplanned pregnancy. 26Just under 10% of participants described as female at birth reported that they switched or stopped using their contraception methods in the past year specifically because of the pandemic.Evidence from other surveillance sources suggests periods of reduced capacity to provide LARC during the pandemic, 5 27 and the pandemic itself might have exacerbated switching or stopping contraception.Pregnancies and abortions in the first year of the pandemic were lower than estimates from a decade earlier.Furthermore, the apparent fall in abortions may be greater since Natsal-COVID-2 employed a more direct question ('have you ever

had an abortion?' prompting 'Year of most recent abortion'), less prone to underreporting than the indirect measure used in Natsal-3 ('Have you ever been pregnant?',prompting 'What was the outcome of that pregnancy?' with 'termination or abortion' as possible response). 28Surveillance data showing stable conception and rising abortion trends in the prior decade suggest that the pandemic contributed to reductions observed between the surveys.The findings are consistent with a global review suggesting decreased access to abortion and reduced intention to get pregnant, especially for individuals facing housing and food insecurity. 29 30The greater reduction in unplanned compared with ambivalent or planned pregnancies might be due to fewer new partners and less casual sex.
Distress and dissatisfaction with one's sex life were common during the pandemic, more so than 10 years previously in Natsal-3.The increased level of sexual distress and avoidance of sex among MSM in our study is striking.The finding that a quarter of Natsal-COVID-2 participants perceived their sex life during the pandemic to be worse than the previous year, adds to a suggested pandemic influence, and is supported by systematic review evidence suggesting an increase in sexual difficulties. 31Longitudinal tracking over the course of the pandemic is rare, though a study in Canada found no change in solitary desire and a decrease in dyadic desire between April and August 2020. 32Studies have linked declines in sexual satisfaction with being young, single or in a poor-quality relationship, and mental distress. 8hile all the data sources we report here have limitations, they provide largely consistent evidence about the effects of the pandemic on SRH, which is supported by an emerging literature. 8aken together, these data suggest COVID-19 had a significant influence on sexual and reproductive health, probably through a combination of restrictions on social mixing, disruption to SRH services, and pandemic-related uncertainty and stress.However, the longer-term implications are difficult to predict.It is unclear what might happen to STI incidence, not least because of uncertainties about sexual behaviours in the future, which might return to pre-pandemic levels or higher.Careful monitoring and research will be required.Similarly, disruptions to contraceptive uptake and pregnancy planning will be important to track, not only to safeguard individual control of fertility but to assess the sociodemographic impact of shifts in trend.
In recovery, it will be critical for public health messaging to emphasise safer sexual behaviour and STI testing.People may need reminding about the availability of free and confidential services, which in the UK include asymptomatic testing and PrEP.This is particularly important because some young people may have missed out on sex education due to school closure and disruption. 33It will be crucial to address intensified disparities in sexual and reproductive health arising from marginalised sexual and gender identities, especially where they intersect with ethnicity and poverty. 34The evidence suggests that detrimental impacts of the pandemic on sexual behaviour, function and mental health are closely intertwined, 8 suggesting that an integrated approach to recovery is required.
