RESUMEN

BACKGROUND: The narrative surrounding women's reproductive health has shifted from a medical model to an emphasis on reproductive well-being over different life-stages. We developed and piloted a tracker survey for monitoring women's reproductive health and well-being in England, recruiting respondents online. This paper reports on the success of the online recruitment strategies in achieving a sample proportionally representative of the England general population. METHODS: Recruitment was through Facebook and Instagram advertisements and dissemination through Twitter and a blog. At the end week one, the sample was reviewed and compared to the 2011 Census England population. From week two, recruitment targeted under-represented groups. Key data were compared with prevalence estimates from the Third National Survey of Sexual Attitudes and Lifestyles (Natsal-3). RESULTS: Between 1 July-17 August 2021, 13,962 people initiated the online survey, with 11,578 completing it. Numbers were low initially, but peaked at 1700 survey initiations per day after increasing the daily advertisement budget on day seven. At the end of week one, minority ethnic groups and people without a degree or equivalent were under-represented. From week two, we altered the advertisement settings to show to people whose profile indicated they were a 'high school leaver' had 'up to some high school', worked in industries that do not typically require a degree or lived in local authorities with a high proportion of ethnic minority residents. This had a modest effect, with the final sample short of proportional representation in terms of ethnicity and education but close in terms of region and age. Compared to Natsal-3, we found consistency in the proportion of respondents reporting an abortion and a live birth in the last year, however, the proportion of our sample reporting ever having experienced infertility was significantly higher than in Natsal-3, as was the proportion of 'planned' pregnancies in the last year. CONCLUSIONS: It is possible to recruit large numbers of respondents online, relatively quickly, to complete a reproductive health survey. This will be valuable to track reproductive health and well-being at a national level over time. More work is needed to understand reasons for non-response among under-represented groups.

RESUMEN

BACKGROUND: Many pregnancies in the UK are either unplanned or ambivalent. This review aimed to (i) explore barriers and facilitators to women choosing and accessing a preferred method of contraception in the United Kingdom, and (ii) identify opportunities for behavioural interventions based on examination of interventions that are currently available nationally. METHODS: Three databases were searched, and experts contacted to identify grey literature for studies presenting barriers and facilitators to women choosing and accessing a preferred method of contraception, conducted in the UK and published between 2009 and October 2019. Information on barriers and facilitators were coded into overarching themes, which were then coded into Mechanisms of Actions (MoAs) as listed in the Theory and Techniques Tool. National interventions were identified by consulting stakeholders and coded into the Behaviour Change Wheel. The match between barriers/facilitators and intervention content was assessed using the Behaviour Change Wheel. RESULTS: We included 32 studies and identified 46 barrier and facilitator themes. The most cited MoA was Environmental Context and Resources, which primarily related to the services women had access to and care they received. Social Influences, Beliefs about Consequences (e.g., side effects) and Knowledge were also key. The behavioural analysis highlighted four priority intervention functions (Modelling, Enablement, Education and Environmental Restructuring) that can be targeted to support women to choose and access their preferred method of contraception. Relevant policy categories and behaviour change techniques are also highlighted. CONCLUSIONS: This review highlights factors that influence women's choices and access to contraception and recommends opportunities that may be targeted for future interventions in order to support women to access preferred contraception. REGISTRATION: Protocol was registered with PROSPERO (an international database of prospectively registered systematic reviews in health and social care) in December 2019, CRD42019161156 .

RESUMEN

There is growing interest in preconception health as a crucial period for influencing not only pregnancy outcomes, but also future maternal and child health, and prevention of long-term medical conditions. Successive national and international policy documents emphasise the need to improve preconception health, but resources and action have not followed through with these goals. We argue for a dual intervention strategy at both the public health level (eg, by improving the food environment) and at the individual level (eg, by better identification of those planning a pregnancy who would benefit from support to optimise health before conception) in order to raise awareness of preconception health and to normalise the notion of planning and preparing for pregnancy. Existing strategies that target common risks factors, such as obesity and smoking, should recognise the preconception period as one that offers special opportunity for intervention, based on evidence from life-course epidemiology, developmental (embryo) programming around the time of conception, and maternal motivation. To describe and monitor preconception health in England, we propose an annual report card using metrics from multiple routine data sources. Such a report card should serve to hold governments and other relevant agencies to account for delivering interventions to improve preconception health.

RESUMEN

It is increasingly recognised that the preconception period is a window of opportunity to intervene to improve outcomes for women and the next generation. The importance of preconception mental health and comorbidity problems has not traditionally been taken into account by policy makers or mental health service providers. We argue that by addressing preconception physical and mental health in men and women, medical health professionals could improve health outcomes across the whole life course.

RESUMEN

OBJECTIVE: To assess the association of symptoms of depression and anxiety with sexual risk behaviour and history, among women and heterosexual men attending genitourinary medicine (GUM) clinics. METHODS: Attitudes to and Understanding of Risk of Acquisition of HIV (AURAH) was a cross-sectional, self-administered questionnaire study recruited from 20 GUM clinics in England, 2013-2014. This analysis included women and heterosexual men. The prevalence of depression and anxiety symptoms was assessed. Modified Poisson regression was used to produce adjusted prevalence ratios (aPR) for the association of t demographic, socioeconomic and lifestyle factors with depression and anxiety, adjusted for gender, age, ethnicity, education level and study region. Among individuals reporting sex in the past 3 months, associations of depression and anxiety with sexual risk behaviour and history were assessed separately by gender, adjusted for age, ethnicity, study region, education and relationship status. RESULTS: Questionnaires were completed by 676 women and 470 heterosexual men. Depression symptoms were reported by 100 (14.8%) women and 33 men (7.0%). Anxiety symptoms were reported by 79 women (11.7%) and 21 men (4.5%). Among women reporting recent sex, those with depression symptoms were more likely to report condomless sex with a non-regular partner, aPR 1.38 (1.07-1.77) and recent condomless sex with two or more partners, 1.80 (1.25-2.59). Women with anxiety symptoms more likely to report recent condomless sex with two or more partners, 1.68 (1.13-2.50), low self-efficacy for condom use, 1.54 (1.02-2.31) and STI diagnosis in the last year 1.51 (1.04-2.20). Among heterosexual men reporting recent sex, depression and anxiety symptoms were associated with low self-efficacy with condom use, 2.32 (1.29-4.19) for depression and 2.23 (1.26-3.94) for anxiety, but not with measures of condomless sex. DISCUSSION: The associations between psychological symptoms and sexual risk behaviours highlight the importance of holistic assessment of need by both general and sexual health clinicians. We highlight the challenge in delivering holistic care associated with fragmentation of sexual health services.

RESUMEN

OBJECTIVE: Genome-wide association studies have identified a large number of single nucleotide polymorphisms (SNPs) associated with a wide array of cancer sites. Several of these variants demonstrate associations with multiple cancers, suggesting pleiotropic effects and shared biological mechanisms across some cancers. We hypothesised that SNPs previously associated with other cancers may additionally be associated with colorectal cancer. In a large-scale study, we examined 171 SNPs previously associated with 18 different cancers for their associations with colorectal cancer. DESIGN: We examined 13 338 colorectal cancer cases and 40 967 controls from three consortia: Population Architecture using Genomics and Epidemiology (PAGE), Genetic Epidemiology of Colorectal Cancer (GECCO), and the Colon Cancer Family Registry (CCFR). Study-specific logistic regression results, adjusted for age, sex, principal components of genetic ancestry, and/or study specific factors (as relevant) were combined using fixed-effect meta-analyses to evaluate the association between each SNP and colorectal cancer risk. A Bonferroni-corrected p value of 2.92×10(-4) was used to determine statistical significance of the associations. RESULTS: Two correlated SNPs--rs10090154 and rs4242382--in Region 1 of chromosome 8q24, a prostate cancer susceptibility region, demonstrated statistically significant associations with colorectal cancer risk. The most significant association was observed with rs4242382 (meta-analysis OR=1.12; 95% CI 1.07 to 1.18; p=1.74×10(-5)), which also demonstrated similar associations across racial/ethnic populations and anatomical sub-sites. CONCLUSIONS: This is the first study to clearly demonstrate Region 1 of chromosome 8q24 as a susceptibility locus for colorectal cancer; thus, adding colorectal cancer to the list of cancer sites linked to this particular multicancer risk region at 8q24.

RESUMEN

BACKGROUND: Extended use of the combined oral contraceptive pill (COC), defined as taking active pills for at least 28 days, has been used in order to avoid bleeding at important times and to treat gynaecological conditions such as endometriosis. We examined the main issues involved in extended use of the COC and how it has evolved from being one of medicine's best-kept secrets to becoming more widely accepted by women and the medical community. STUDY DESIGN: Literature review, using Medline, Embase, Pubmed, CINHAL Plus, the Cochrane Database of Systematic Reviews and the Ovid database for all relevant clinical trials, systematic reviews, meta-analyses, literature reviews, scientific papers and individual opinions between 1950 and October 2013. RESULTS: Accumulating evidence supports various forms of extended pill use as suitable alternatives to the standard (21/7) regimen. In terms of user preference, much hinges on whether women wish to reduce the frequency or duration of scheduled bleeding on the combined pill. Available data on the safety of extended pill regimens do not give cause for concern, but longer term data should be collected. CONCLUSIONS: Information for women considering extended COC regimens should keep pace with research findings to ensure that women and clinicians are better informed about the choices available.

RESUMEN

BACKGROUND: England has invested in chlamydia screening interventions for young people. It is not known whether young people in poorer socioeconomic circumstances (SEC) are at greater risk of chlamydia and therefore in greater need of screening. OBJECTIVE: To conduct a systematic review examining socioeconomic variations in chlamydia prevalence or positivity in young people. DATA SOURCES: Eight bibliographic databases using terms related to chlamydia and SEC, supplemented by website and reference searches. ELIGIBILITY: Studies published 1999-2011 in North America, Western Europe, Australia or New Zealand, including populations aged 15-24 years, with chlamydia prevalence or positivity diagnosed by nucleic acid amplification testing. APPRAISAL AND SYNTHESIS: Two reviewers independently screened references, extracted data, appraised studies meeting inclusion criteria and rated studies as high, medium or low according to their quality and relevance. Socioeconomic variations in chlamydia were synthesised for medium/high-rated studies only. RESULTS: No high-rated studies were identified. Eight medium-rated studies reported variations in chlamydia prevalence by SEC. In 6/8 studies, prevalence was higher in people of poorer SEC. Associations were more often significant when measured by education than when using other indicators. All studies measuring positivity were rated low. Across all studies, methodological limitations in SEC measurement were identified. CONCLUSIONS: The current literature is limited in its capacity to describe associations between SEC and chlamydia risk. The choice of SEC measure may explain why some studies find higher chlamydia prevalence in young people in disadvantaged circumstances while others do not. Studies using appropriate SEC indicators (eg, education) are needed to inform decisions about targeting chlamydia screening.

RESUMEN

INTRODUCTION: Over-the-counter provision of emergency contraception pills (ECP) has increased since deregulation of progestogen-only formulations and is now the most common public health service provided by UK pharmacists. Important questions relate to women's perceptions of their experience of receiving ECPs from pharmacists. METHODS: Qualitative study: in-depth interviews with young women reporting ECP use, recruited from clinic (10); pharmacy (6) and community settings (5) in London. RESULTS: Key advantages of pharmacy provision were ease and speed of access and convenience. Disadvantages included a less personal service, inadequate attention to information needs and to prevention of recurrence of ECP need, and unsupportive attitudes of pharmacy staff. Suggested service improvements included increasing privacy, providing more contraceptive advice, adopting a more empathetic approach and signposting follow-up services. CONCLUSION: Pharmacies are important in the choice of settings from which ECPs can be obtained and many aspects of pharmacy provision are appreciated by young women. There is scope to further enhance pharmacists' role.

RESUMEN

BACKGROUND: Quitline smoking cessation counseling results in a mere 12% success rate. Testing of new telephone-delivered cessation counseling approaches is needed. OBJECTIVE: Determine the feasibility of the first telephone-delivered Acceptance and Commitment Therapy (ACT) intervention for smoking cessation. DESIGN: Fourteen adults (57% racial/ethnic minority, 8/14) in a single-arm study. Counselor proactively delivered a 5-session (90-min total) ACT telephone intervention for smoking cessation. Hypothesized ACT processes were self-reported at baseline and posttreatment. Smoking status was self-reported at baseline, 20-day posttreatment (93% retention, 13/14), and 12-month posttreatment (93% retention, 13/14). RESULTS: (a) Delivery length and duration: average of 3.5 calls and 81.9-min intervention duration. (b) Receptivity: 100% (14/14) felt respected by the counselor, 86% (12/14) said that intervention was a good fit, and 93% (13/14) said that intervention helped them quit. (c) ACT processes: (i) acceptance of physical cravings, emotions, and thoughts that cue smoking increased from baseline to posttreatment (p = .001, p = .038, and p = .085, respectively) and (ii) commitment to quitting increased from baseline to posttreatment (p = .01). (4) Intent-to-treat cessation outcomes: (i) at 20-day posttreatment, 43% (6/14) had not smoked the day of the survey and 29% (4/14) had not smoked in past 7 days and (ii) at 12-month posttreatment, 29% (4/14) had not smoked at all in past 12 months. These quit rates are over double the 12% quit rates of current standard telephone counseling. CONCLUSION: Telephone-delivered ACT shows promise for smoking cessation and warrants future testing in a well-powered randomized trial.

RESUMEN

OBJECTIVES: Provision of immediate postnatal contraception, including long-acting reversible contraceptive (LARC) methods, is increasingly identified and endorsed as a key strategy for reducing unplanned and rapid repeat pregnancies. This literature review aims to evaluatethe views of women and healthcare professionals regarding the receipt, initiation or delivery of these services. METHODS: Databases (Embase, Medline, CINAHL, HMIC) were searched for relevant English language studies, from January2003 to December 2017. In addition, Evidence Search, Google Scholar and Scopus (citation search) were used to identify further literature. Other relevant websites were accessed for policies, guidance and supplementary grey literature. RESULTS: There is clear guidance on how to deliver good-quality postnatal contraception to women, but the reality of service delivery in the UK does not currently meet these aspirations, and guidance on implementation is lacking. The available evidence on the provision of immediate postnatal contraception focuses more on clinical rather than patient-centred outcomes. Research on postnatal women's views is limited to receptivity to LARC and contraception counselling rather than what influences their decision-making process at this time. Research on views of healthcare professionals highlights a range of key systemic barriers to implementation. CONCLUSIONS: While views of postnatal women and healthcare professionals are largely in support of immediate postnatal contraception provision, important challenges have been raised and present a need for national sharing of service commissioning and delivery models, resources and evaluation data. Provider attitudes and training needs across multidisciplinary groups also need to be assessed and addressed as collaborative working across a motivated, skilled and up-to-date network of healthcare professionals is viewed as key to successful service implementation.

RESUMEN

INTRODUCTION: Postpartum women are at risk of rapid repeat, unplanned pregnancy with associated adverse outcomes for mother and child. We aimed to better understand their contraceptive needs to improve delivery of services and prevent unplanned pregnancies. METHODS: A cross-sectional survey of women on the postnatal ward of an inner-city hospital was administered over a 6-week period in June and July 2017 to determine their level of knowledge, intentions and preferences regarding postnatal contraception. RESULTS: 272 women were surveyed: 86% of all women on the postnatal ward during the study period. 10% (26/272) had never used any method of contraception previously and 22% (59/272) had ever used a long-acting reversible contraception (LARC) method. 18% (48/272) recalled a health professional speaking to them about contraception at any point during their pregnancy and 32% (87/272) said they needed more information to decide on their postnatal contraceptive method. 54% (147/272) of women did not think any LARC methods were safe immediately postnatally, rising to 71% (194/272) if breastfeeding. However, 47% (129/272) of women said that they would prefer to get their contraception from the ward before discharge and 46% (126/272) were likely to accept LARC, if safe, in this setting. CONCLUSIONS: Almost half the women in our survey would welcome provision of postnatal contraception, including LARC, on the postnatal ward but the women surveyed currently lack the knowledge to make informed choices in this setting. There is therefore a need for effective, tailored contraceptive choices discussions with every woman during pregnancy, as well as integrated planning for postnatal provision of the woman's chosen method.

RESUMEN

Women and men globally are delaying the birth of their first child. In the UK, the average age of first conception in women is 29 years. Women experience age-related fertility decline so it is important that men and women are well-informed about this, and other aspects of fertility. A group of UK stakeholders have established the Fertility Education Initiative to develop tools and information for children, adults, teachers, parents and healthcare professionals dedicated to improving knowledge of fertility and reproductive health.

RESUMEN

Postpartum care (PPC) has remained relatively neglected in many interventions designed to improve maternal and neonatal health in sub-Saharan Africa. The Missed Opportunities in Maternal and Infant Health project developed and implemented a context-specific package of health system strengthening and demand generation in four African countries, aiming to improve access and quality of PPC. A realist evaluation was conducted to enable nuanced understanding of the influence of different contextual factors on both the implementation and impacts of the interventions. Mixed methods were used to collect data and test hypothesised context-mechanism-outcome configurations: 16 case studies (including interviews, observations, monitoring data on key healthcare processes and outcomes), monitoring data for all study health facilities and communities, document analysis and participatory evaluation workshops. After evaluation in individual countries, a cross-country analysis was conducted that led to the development of four middle-range theories. Community health workers (CHWs) were key assets in shifting demand for PPC by 'bridging' communities and facilities. Because they were chosen from the community they served, they gained trust from the community and an intrinsic sense of responsibility. Furthermore, if a critical mass of women seek postpartum healthcare as a result of the CHWs bridging function, a 'buzz' for change is created, leading eventually to the acceptability and perceived value of attending for PPC that outweighs the costs of attending the health facility. On the supply side, rigid vertical hierarchies and defined roles for health facility workers (HFWs) impede integration of maternal and infant health services. Additionally, HFWs fear being judged negatively which overrides the self-efficacy that could potentially be gained from PPC training. Instead the main driver of HFWs' motivation to provide comprehensive PPC is dependent on accountability systems for delivering PPC created by other programmes. The realist evaluation offers insights into some of the contextual factors that can be pivotal in enabling the community-level and service-level interventions to be effective.

RESUMEN

BACKGROUND: The purpose of this study was to determine attitudes to, and provision of, extended regimens for taking the combined oral contraceptive pill (COC) by specialist contraception practitioners from three contrasting specialist contraception services in London. METHODS: An online cross-sectional survey was administered to all doctors and nurses, who counsel, provide, or prescribe the oral contraceptive pill at each clinic. RESULTS: A total of 105 clinicians received the questionnaire and 67 (64%) responded. Only one of three clinics initiated and maintained guidelines for extended COC use. In that service, 60% of staff prescribing COC advised more than 50% of patients regarding alternative COC regimens. In the other two services, this was discussed with 20% and 6% of patients, respectively (P < 0.001). The reasons for prescribing extended use included cyclic headaches, menorrhagia, patient request, menstrual-related cramps, and endometriosis, and did not differ between the three different settings. The most common extended regimens were 63 pills or continuous use until bleeding occurs, followed by a hormone-free interval. Concerns highlighted by providers and patients were "unhealthy not to have a monthly bleed", "future fertility", and "breakthrough bleeding". Such comments highlight the need for further information for providers and patients. CONCLUSION: There is growing evidence, backed by national guidance, about extended COC use, but routine provision of this information is patchy and varies ten-fold, even within specialist family planning services. Targeted training, use of service guidelines, and implementation research will be needed to extend patient choice of different COC regimens and change clinical practice.

RESUMEN

BACKGROUND: Genome-wide association studies (GWAS) have identified loci associated with ischemic stroke (IS) and cardiovascular disease (CVD) in European-descent individuals, but their replication in different populations has been largely unexplored. METHODS AND RESULTS: Nine single nucleotide polymorphisms (SNPs) selected from GWAS and meta-analyses of stroke, and 86 SNPs previously associated with myocardial infarction and CVD risk factors, including blood lipids (high density lipoprotein [HDL], low density lipoprotein [LDL], and triglycerides), type 2 diabetes, and body mass index (BMI), were investigated for associations with incident IS in European Americans (EA) N=26 276, African-Americans (AA) N=8970, and American Indians (AI) N=3570 from the Population Architecture using Genomics and Epidemiology Study. Ancestry-specific fixed effects meta-analysis with inverse variance weighting was used to combine study-specific log hazard ratios from Cox proportional hazards models. Two of 9 stroke SNPs (rs783396 and rs1804689) were significantly associated with [corrected] IS hazard in AA; none were significant in this large EA cohort. Of 73 CVD risk factor SNPs tested in EA, 2 (HDL and triglycerides SNPs) were associated with IS. In AA, SNPs associated with LDL, HDL, and BMI were significantly associated with IS (3 of 86 SNPs tested). Out of 58 SNPs tested in AI, 1 LDL SNP was significantly associated with IS. CONCLUSIONS: Our analyses showing lack of replication in spite of reasonable power for many stroke SNPs and differing results by ancestry highlight the need to follow up on GWAS findings and conduct genetic association studies in diverse populations. We found modest IS associations with BMI and lipids SNPs, though these findings require confirmation.
