Midwives' and registered nurses' role and scope of practice in acute early pregnancy care services: a scoping review.

OBJECTIVE: The objective of this scoping review was to investigate and describe what is reported on the role and scope of practice of midwives and registered nurses providing care for women with pregnancy complications under 20 weeks' gestation in acute clinical settings in Australia. INTRODUCTION: In many high-income countries, women experiencing unexpected complications in early pregnancy attend an acute care service, such as an emergency department, rather than a maternity or obstetric unit. This service structure can impact the care women receive, and determine who provides it. Women and their partners, who are often experiencing emotional distress, have reported difficult experiences when accessing acute services, particularly emergency departments, which are not traditionally staffed by midwives. The role and scope of practice of both midwives and registered nurses providing acute early pregnancy care in most high-income countries, including Australia, is poorly reported. Documenting this area of practice is an important first step in facilitating ongoing research in this important aspect of pregnancy care. INCLUSION CRITERIA: Published and gray literature that described the role and scope of practice of midwives and/or registered nurses providing care in acute early pregnancy settings in Australia were considered for this review. METHODS: A scoping review of the literature was conducted following JBI methodological guidance and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) checklist. A 3-step search strategy was conducted to explore evidence from databases and search engines, gray literature sources, and selected reference lists. After screening, data were extracted from records selected for the final review, mapped, and analyzed using content analysis. RESULTS: The evidence reviewed (n=23) included primary research studies, conference abstracts, and gray literature, such as clinical guidance documents, academic theses, and websites from January 2008 to October 2023. The most common setting for care provision was the emergency department. Midwives' and registered nurses' roles and scope of practice in acute early pregnancy care in Australia can be summarized into 4 areas: physical care, psychosocial support, care co-ordination, and communication. Women's access to midwifery care at this time in pregnancy appears to be limited. Registered nurses, usually employed in emergency departments, have the most prominent role and scope in the provision of care for women with acute early pregnancy complications. Descriptions of midwives' practice focuses more on psychosocial support and follow-up care, particularly in early pregnancy assessment service models. CONCLUSIONS: This review highlights the inconsistency in midwives' and registered nurses' roles and scope in acute early pregnancy in Australia, a finding which is relevant to other international settings. Both professions could further fulfill role and scope capacity in the provision of supportive, individualized, and timely care for women and families accessing a range of acute early pregnancy services. Emergency departments are the usual practice domain of registered nurses who may be limited in terms of the scope of care they can provide to women with early pregnancy complications. Leaders of the midwifery profession should conduct further research into innovative service models that embed a role for midwives in all settings that provide care for pregnant women, regardless of gestation.

An exploration of the contraceptive counselling practices of midwives who provide postpartum care in Australia.

OBJECTIVE: We sought to explore and describe midwives' attitudes and practices relating to their provision of postpartum contraception counselling. DESIGN: We used an exploratory cross-sectional design. Recruitment used an anonymous online survey using electronic communication platforms of professional, and special-interest organisations, over six months . Descriptive and quantitative analysis was used. SETTING AND PARTICIPANTS: Australian Midwives who provide postpartum care. MEANING AND FINDINGS: A total of 289 complete responses were included. Findings from this national survey of midwives showed that almost 75% of Australian midwives reported providing some contraceptive advice to women. Those working in continuity of care models were significantly more likely to fulfil this responsibility. More than half (67%) indicated they had not received any formal contraception education or training. Those working in private obstetric-led settings were significantly less likely to have received education compared to midwives in community settings. Systems barriers preventing the provision of contraceptive counselling included: clinical workload; lack of management support; lack of education; and models of care. KEY CONCLUSIONS: Most midwives (82%) wanted to provide postpartum contraception counselling as part of their role. They cited barriers from within the health system, ambiguity about roles and responsibilities and offered solutions to improve the provision of postnatal contraception counselling. IMPLICATIONS FOR PRACTICE: Recommendations include the development of education programs for midwives. Continuity of care models provided the time, autonomy and opportunity for midwives to undertake contraceptive counselling and fulfil this part of their professional scope. Consideration should be given to expanding access and provision of continuity of midwifery care. An urgent investment in the education and skills of midwives is recommended to ensure all women across acute and community services benefit from improved outcomes associated with pregnancy spacing.

Using a validated instrument to assess pregnancy planning and preconception care at antenatal booking visits: a retrospective cohort study.

OBJECTIVE: To determine the completion rate for the London Measure of Unplanned Pregnancy (LMUP), a psychometrically validated measure of a woman's intention with regard to a current or recent pregnancy, during booking visits at two metropolitan antenatal care clinics; to identify socio-demographic characteristics associated with unplanned pregnancy. DESIGN, SETTING, PARTICIPANTS: Retrospective cohort study; analysis of LMUP data for women attending antenatal care booking consultations as public patients in the Sydney Local Health District, 31 December 2019 - 30 November 2020. MAIN OUTCOME MEASURES: Proportions of women with LMUP scores indicating unplanned (0-9) or planned pregnancies (10-12); associations between planned pregnancy and socio-demographic characteristics, crude and adjusted for age, parity, and socio-economic status (Index of Relative Socioeconomic Disadvantage). RESULTS: Of 4993 women with antenatal care bookings, the LMUP was completed by 2385 (47.8%; 1142 of 3564 women at the tertiary referral hospital [32.0%], 1118 of 1160 at the secondary hospital [96.3%]). Planned pregnancies were indicated by the total LMUP scores of 1684 women (70.6%); 1290 women (59.1%) reported no health actions in preparation for pregnancy. In multivariable analyses, planned pregnancies were more likely in all age groups than for women aged 24 years or younger (30-34 years: adjusted odds ratio [aOR], 2.54; 95% confidence interval [CI], 1.76-3.66; 35-39 years: aOR, 2.91; 95% CI, 1.95-4.33). The likelihood of planned pregnancy declined with increasing parity (v no previous births: three previous births: aOR, 0.25; 95% CI, 0.16-0.40; four or more previous births: aOR, 0.10; 95% CI, 0.05-0.19). CONCLUSION: Seven in ten women who completed the LMUP had planned their pregnancies, but fewer than half had undertaken health-related actions prior to conceiving. Higher parity was associated with unplanned pregnancy, indicating the importance of postpartum contraception advice. Overcoming barriers to implementing the LMUP more widely would enhance preconception health monitoring.

Addressing Preconception Behavior Change Through Mobile Phone Apps: Systematic Review and Meta-analysis.

BACKGROUND: Positive health behavior changes before pregnancy can optimize perinatal outcomes for mothers, babies, and future generations. Women are often motivated to positively change their behavior in preparation for pregnancy to enhance their health and well-being. Mobile phone apps may provide an opportunity to deliver public health interventions during the preconception period. OBJECTIVE: This review aimed to synthesize the evidence of the effectiveness of mobile phone apps in promoting positive behavior changes in women of reproductive age before they are pregnant (preconception and interconception periods), which may improve future outcomes for mothers and babies. METHODS: Five databases were searched in February 2022 for studies exploring mobile phone apps as a prepregnancy intervention to promote positive behavior change. The identified studies were retrieved and exported to EndNote (Thomson Reuters). Using Covidence (Veritas Health Innovation), a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) study flow diagram was generated to map the number of records identified, included, and excluded. Three independent reviewers assessed the risk of bias and conducted data extraction using the Review Manager software (version 5.4, The Cochrane Collaboration), and the data were then pooled using a random-effects model. The Grades of Recommendation, Assessment, Development, and Evaluation system was used to assess the certainty of the evidence. RESULTS: Of the 2973 publications identified, 7 (0.24%) were included. The total number of participants across the 7 trials was 3161. Of the 7 studies, 4 (57%) included participants in the interconception period, and 3 (43%) included women in the preconception period. Of the 7 studies, 5 (71%) studies focused on weight reduction, assessing the outcomes of reductions in adiposity and weight. Of the 7 studies, nutrition and dietary outcomes were evaluated in 2 (29%) studies, blood pressure outcomes were compared in 4 (57%) studies, and biochemical and marker outcomes associated with managing disease symptoms were included in 4 (57%) studies. Analysis showed that there were no statistically significant differences in energy intake; weight loss; body fat; and biomarkers such as glycated hemoglobin, total cholesterol, fasting lipid profiles, or blood pressure when compared with standard care. CONCLUSIONS: Owing to the limited number of studies and low certainty of the evidence, no firm conclusions can be drawn on the effects of mobile phone app interventions on promoting positive behavior changes in women of reproductive age before they are pregnant (preconception and interconception periods).

Scoping review into models of interconception care delivered at well-child visits for the Australian context.

BACKGROUND: The interconception period provides an opportunity to address women's health risks and optimise birth spacing before the next pregnancy. This scoping review aimed to identify models of interconception care (ICC) delivered at well-child visits (WCVs) around the world, review the impacts of ICC delivered, and what the feasibility and applicability of these models were. METHODS: The global review included clinical studies that that were identified using medical subject headings (MeSH) and keyword combinations. Studies were included if they met the criteria: were clinical studies; examined a model of ICC; were conducted by a registered health professional; and examined women who had given birth within the last 24-months. The following databases were searched: Medline (OVID); CINAHL (EBSCO); PubMed; and Embase (OVID). Relevant studies were screened in Covidence and the data was then extracted using a narrative analysis. RESULTS: Fifteen studies met the inclusion criteria. The benefits of ICC delivered at WCVs included screening for maternal health behaviours and conditions and increase women's uptake of interventions. The studies identified that implementing ICC at WCVs was acceptable to women. Identified challenges included lack of time for health providers, lack of education among women and health providers, and limited funding for WCVs. CONCLUSION: ICC interventions found in this review included family planning counselling and provision of long-acting contraception; health promotion of folic acid; and postpartum depression screening. The research concluded that ICC delivered at WCVs contributes to improving health behaviours for future pregnancies. Increased capacity for this care at WCVs could be achieved with targeted resources and time allocation.

Midwives' and registered nurses' role and scope of practice in acute early pregnancy care services in Australia: a scoping review protocol.

OBJECTIVE: The objective of this review is to review and synthesize what is documented on the role and scope of practice of midwives and registered nurses working in acute early pregnancy care settings in Australia. INTRODUCTION: Women experiencing complications before 20 weeks of pregnancy may need to attend an acute care service, often a hospital emergency department. Midwives and registered nurses provide care for women with early pregnancy complications, and it is important that their role and scope of practice is documented. This review will explore the literature relating to acute early pregnancy care in Australia to better understand how midwives' and registered nurses' roles and scope are currently described in this setting. INCLUSION CRITERIA: Any literature that explores the role and scope of practice of midwives and registered nurses who care for women who present to acute care services in Australia with early pregnancy complications will be considered for inclusion in the review. METHODS: A 3-step review process will involve a preliminary search of MEDLINE and ProQuest, followed by a more detailed search of a larger selection of databases, using identified keywords and phrases from the initial search. Reference lists of retrieved literature will then be examined for relevant citations. Literature in English will be considered, including relevant gray literature. Search results will be imported into reference and review support software. Data that align with the inclusion criteria will be organized into tabulated and narrative formats for presentation.

Introduction of the London Measure of Unplanned Pregnancy at the booking visit and the midwives' perspective.

BACKGROUND: Pregnancy planning and preconception care benefit women, their children, and future generations. The London Measure of Unplanned Pregnancy (LMUP) is a tool that can be used in antenatal care to identify women with unintended pregnancies who require improved access to such services. This tool was recently implemented into routine antenatal care in two maternity centres in New South Wales, Australia. This study explores midwives' attitudes to the LMUP 12 months after it was introduced into the booking visit and their understanding of its application to their scope of practice. METHODS: This is a qualitative study using in-depth semi-structured interviews with midwives from two maternity care centres in Australia. All midwives performing antenatal booking visits were eligible to take part. Interviews were transcribed, analysed, and coded to define key themes. Recruitment ceased when thematic saturation was reached. RESULTS: Ten midwives from two maternity centres were interviewed. Midwives support the inclusion of the LMUP into the booking visit and felt it was in their scope of practice to be using the tool. Time constraints, the impact of COVID-19 and the lack of structured referral pathways were identified as barriers to the implementation of the LMUP in routine care. CONCLUSIONS: Midwives support the inclusion of the LMUP into the antenatal booking visit and see that it falls within their scope of practice. Service barriers were identified at the individual, organisational and external context levels. These need to be addressed to enhance the potential of this tool.

A cross-sectional study of women's autonomy and modern contraception use in Zambia.

BACKGROUND: Modern contraceptive use effectively prevents unwanted pregnancies, promoting maternal and child health and improving the socio-economic well-being of women and their families. Women's autonomy has been shown to increase the uptake of modern contraception use. This research aimed to investigate the relationship between measures of women's autonomy and modern contraception use among partnered women in Zambia. METHODS: This cross-sectional survey study used data from the health census, the 2018 Zambia Demographic Health Survey. We measured women's autonomy using three indices: women's participation in decision-making, women's attitude towards wife-beating and women's household status. Information from 6727 women in a relationship, not pregnant, not planning pregnancy and aged between 15 and 49 years old were analyzed using descriptive statistics and adjusted odds ratios (AOR). RESULTS: The mean age of respondents was 32 years. Most women lived in rural areas (65%), and 81% were protestant. Current modern contraception use among partnered women was 8.8%. Women's autonomy was significantly associated with modern contraception use. Women with moderate autonomy (AOR = 1.054, P value = 0.004, 95% CI 1.048-1.312) and high autonomy (AOR = 1.031, P value = 0.001, 95% CI 1.013-1.562) had higher odds of using modern contraception compared to those with low autonomy. Other factors related to modern contraception use included a higher level of education (AOR = 1.181, P value = 0.012, 95% CI 1.091-1.783), increased wealth index (AOR = 1.230, P value = 0.006, 95% CI 1.105-1.766) and age, 15-24 (AOR = 1.266, P value = 0.007, 95% CI 1.182-2.113,) and 25-34 (AOR = 1.163, P value = 0.002, 95% CI 1.052-1.273). CONCLUSION: This study argues that increasing women's assertiveness to make independent decisions within the household is cardinal to enhancing the uptake of modern contraception in Zambia and other low-and-middle-income countries. Governments and other stakeholders must therefore consider rolling out programs to boost women's autonomy, which in turn would support gender equality and reproductive health.

Setting Preconception Care Priorities in Australia Using a Delphi Technique.

Preconception health affects fertility, pregnancy, and future health outcomes but public awareness of this is low. Our aims were to rank priorities for preconception care (PCC), develop strategies to address these priorities, and establish values to guide future work in preconception healthcare in Australia. A Delphi technique involved two rounds of online voting and mid-round workshops. Inputs were a scoping review of PCC guidelines, a priority setting framework and existing networks that focus on health. During July and August, 2021, 23 multidisciplinary experts in PCC or social care, including a consumer advocate, completed the Delphi technique. Ten priority areas were identified, with health behaviors, medical history, weight, and reproductive health ranked most highly. Six strategies were identified. Underpinning values encompassed engagement with stakeholders, a life course view of preconception health, an integrated multi-sectorial approach and a need for large scale collaboration to implement interventions that deliver impact across health care, social care, policy and population health. Priority populations were considered within the social determinants of health. Health behaviors, medical history, weight, and reproductive health were ranked highly as PCC priorities. Key strategies to address priorities should be implemented with consideration of values that improve the preconception health of all Australians.

Short interpregnancy interval: circumstance or choice?

INTRODUCTION: Despite the knowledge of pregnancy risks attributable to inadequate birth spacing, over one-third of pregnancies occur within 18 months of a preceding birth. In this qualitative study we sought to interview women with a short interpregnancy interval (sIPI) to explore their knowledge of contraception and birth spacing and their experience of counselling on these themes. METHODS: We conducted in-depth interviews with women with a sIPI (live-birth less than 18 months prior to conception of current pregnancy) at Royal Prince Alfred Hospital and Canterbury Hospital in Sydney, Australia. Women were recruited at the second antenatal visit or day 3 postpartum. Interviews were recorded and transcribed. The six-phase thematic analysis framework described by Braun and Clarke was used to perform qualitative data analysis. RESULTS: Twenty women were interviewed (IPI range: 3-18 months). The three central themes that arose were that perceptions of IPIs are shaped by individual circumstances, a lack of information from healthcare providers (HCPs) on IPI and contraception limited women's ability to make informed decisions, and that reproductive life planning is an important element of pregnancy care. CONCLUSIONS: In this study, women with a sIPI did not feel informed about birth spacing, had poor knowledge of reliable contraceptives, and remained at risk of further closely spaced pregnancies. There was a desire among women with a sIPI to receive clear and consistent education on these topics. HCPs need to do more to educate women in the antenatal and postnatal period to help them space their pregnancies appropriately.

To what extent do postpartum contraception policies or guidelines exist in Australia and New Zealand: A document analysis study.

Women are susceptible to unintended, rapid repeat pregnancies in the first 12 months postpartum. Access to postpartum contraception, specifically long-acting reversible contraception, enables better planning of pregnancy timing and spacing and allows optimisation of health before the next conception. Clinical Practice Guidelines (CPG), and implementation policies, supported by consumer input, can improve such access. We searched publicly available Australian and New Zealand guidelines and policy documents addressing postpartum contraception. One CPG detailed specific information about postpartum contraception and, although of high quality, requires modification to local contexts to support implementation and policy development.

The influence of maternal obesity on pregnancy intention: A cross-sectional analysis.

This prospective cross-sectional study of 1498 pregnant women in early pregnancy sought to investigate the prevalence of pregnancy intention between women of differing body mass index (BMI) categories. There was no difference in the risk of unintended pregnancy between women who were in the healthy weight, overweight or obesity BMI categories. The study identifies and highlights the potential missed opportunities for all women to engage in healthy reproductive life planning behaviours to support health in pregnancy and beyond.

Interpregnancy intervals and women's knowledge of the ideal timing between birth and conception.

BACKGROUND: Short interpregnancy intervals (IPIs) are associated with adverse obstetric outcomes. However, few studies have explored women's understanding of ideal IPIs or investigated knowledge of the consequences of short IPIs. METHODS: We performed a prospective questionnaire-based study at two hospitals in Sydney, Australia. We recruited women attending antenatal clinics and collected demographic data, actual IPI, ideal IPI, contraceptive use, and education provided on birth-spacing and contraception following a previous live birth. We explored associations between an IPI <12 months and a selection of demographic and health variables. RESULTS: Data were collected from 467 women, of whom 344 were pregnant following a live birth. Overall, 72 (20.9%) women had an IPI <12 months only 7.5% of whom believed this was ideal, and the remaining stating their ideal IPI was over 12 months (52.3%) or they had no ideal IPI (40.3%). IPI <12 months following a live birth was significantly associated with younger age (p=0.043) but not with ethnicity, relationship status, education, religion, parity nor previous mode of delivery. IPI <12 months was associated with non-use of long-acting reversible contraception (LARC) (p<0.001), breastfeeding <12 months (p=0.041) and shorter ideal IPI (p=0.03). Less than half of the women (43.3%, n=149) reported having received advice about IPI and less than half about postnatal contraception (44.2%, n=147). CONCLUSIONS: Younger age and non-use of LARC are significantly associated with IPIs <12 months. A minority of women with a short IPI perceived it to be ideal. Prevention of short IPIs could be achieved with improved access to postnatal contraception.

Population attributable fractions of perinatal outcomes for nulliparous women associated with overweight and obesity, 1990-2014.

OBJECTIVE: To examine the prevalence across 25 years of overweight and obesity among nulliparous Australian women during early pregnancy; to estimate the proportions of adverse perinatal outcomes attributable to overweight and obesity in this population. DESIGN: Cohort study; retrospective analysis of electronic maternity data. Setting, participants: 42 582 nulliparous women with singleton pregnancies giving birth at the Royal Prince Alfred Hospital, an urban teaching hospital in Sydney, January 1990 - December 2014. MAIN OUTCOME MEASURES: Maternal body mass index (BMI), socio-demographic characteristics, and selected maternal, birth and neonatal outcomes; the proportion of adverse perinatal outcomes that could be averted by reducing the prevalence of overweight and obesity in women prior to first pregnancies (population attributable fraction, PAF). RESULTS: The prevalence of overweight among nulliparous pregnant women increased from 12.7% (1990-1994) to 16.4% (2010-2014); the prevalence of obesity rose from 4.8% to 7.3% in the same period, while the proportion with normal range BMIs fell from 73.5% to 68.2%. The PAFs for key adverse maternal and neonatal outcomes increased across the study period; during 2010-2014, 23.8% of pre-eclampsia, 23.4% of fetal macrosomia, and 17.0% of gestational diabetes were attributable to overweight and obesity. Were overweight and obese women to have moved down one BMI category during 2010-2014, 19% of pre-eclampsia, 15.9% of macrosomia, 14.2% of gestational diabetes, 8.5% of caesarean deliveries, 7.1% of low for gestational age birthweight, 6.8% of post partum haemorrhage, 6.5% of admissions to special care nursery, 5.8% of prematurity, and 3.8% of fetal abnormality could have been averted. CONCLUSIONS: Over the past 25 years, the proportions of adverse perinatal outcomes attributable to overweight and obesity have risen with the increasing prevalence of maternal overweight and obesity. A substantial proportion of these outcomes might be averted with obesity prevention strategies that reduce pre-pregnancy maternal weight.

Unintended pregnancy amongst an early pregnancy clinic cohort: Identifying opportunities for preventative health interventions.

BACKGROUND: A relationship between maternal weight and unintended pregnancy has previously been reported. Researchers have found women who are overweight and obese women are less likely to use contraception, and more likely to have unplanned pregnancies, thus limiting their ability to optimise their health before conception. AIMS: This study sought to examine the relationship between pregnancy intention and body mass index (BMI) amongst women attending a service managing early pregnancy complications. MATERIALS AND METHODS: The cross-sectional descriptive study (n = 550) was conducted from November 2013 to February 2015 in Sydney, Australia. It documented women's pregnancy intention using a self-completed questionnaire incorporating a validated pregnancy intention scale and measuring women's height and weight to calculate their BMI using the WHO classification of anthropometry and adjusting for cut-offs in Asian populations. Socio-demographic characteristics were also documented. RESULTS: The respondents were ethnically diverse with over a third defining themselves as Asian (36%; 196). Forty-four per cent of women (239) had clearly intended their pregnancy, 39% (212) were ambivalent and 18% (99) had not intended to conceive. Forty-nine per cent (263) of women were overweight or obese. No relationship was found between pregnancy intention and BMI. CONCLUSIONS: Fewer than half the women with early pregnancy complications clearly intended to be pregnant. Contrary to previous research, pregnancy intention was not associated with maternal weight. Underutilised opportunities for lifestyle and preconception education exist to address the impact of modifiable maternal behaviours on future pregnancies and to provide contraception counselling to those not wishing to conceive.

Factors affecting length of stay for women presenting with early pregnancy complications to a public hospital emergency department.

OBJECTIVE: This study aimed to determine factors associated with length of stay (LOS) for women presenting with early pregnancy complications to a public hospital ED. In particular, we sought to investigate the impact the involvement of the Clinical Midwife Consultant (CMC), specialising in early pregnancy care, had on the ED LOS. METHODS: We undertook a retrospective cohort study of women less than 20 weeks pregnant who presented between August 2008 and December 2010 with early pregnancy complications to the ED of the Royal Prince Alfred Hospital in Sydney, Australia and who were then discharged. The main outcome measured was LOS. We performed logistic regression analysis to identify factors significantly associated with this outcome. RESULTS: Data were available for 1739 women. Involvement of the CMC reduced LOS and patients were significantly more likely to be discharged within 4 h or less (OR = 0.47, 95% CI = 0.37-0.60). The factors that increased LOS to over 4 h were arrival after hours (OR = 2.09, 95% CI = 1.66-2.63), being triaged as category 1 to 3 (OR = 1.36, 95% CI = 1.11-1.67) and requiring an ultrasound assessment (OR = 2.44, 95% CI = 1.81-3.28). CONCLUSIONS: This study was able to show factors significantly associated with ED LOS, many of which are not modifiable. The involvement of the CMC reduced LOS, whereas requiring an ultrasound assessment increased LOS. Thus, improvement could be achieved by greater access to a CMC and more rapid access to ultrasound services.

Chlamydia and associated factors in an under 20s antenatal population.

INTRODUCTION: Detection and treatment of genital chlamydia trachomatis infections in pregnancy have been shown to reduce the risk of premature rupture of membranes, and post-partum endometritis and reduce the risk to the newborn of conjunctivitis and pneumonitis. Identification of factors associated with chlamydial infection in pregnancy could be used to develop criteria for routine chlamydia screening for some pregnant women. No national screening strategy exists around genital Chlamydia trachomatis infection. METHODS: We undertook a review of the medical records of all young women (aged 20 years or younger) attending the RPA Women and Babies Young Parents Clinic for antenatal care between January 2003 and June 2006. This group was chosen as RPA Women and Babies routinely offers testing for C. trachomatis to women attending the Young Parents Clinic. Data extracted included age, country of birth, language spoken at home, postcode of usual residence, marital status, educational level, change of sexual partners within the past 12 months, consistency of condom use and history of sexually transmissible infections. RESULTS: Two hundred and twelve of the 365 eligible pregnant women were screened for genital C. trachomatis, of whom 29 were positive. A rate of 13.7% genital chlamydia infection was found in this population of young pregnant women. CONCLUSIONS: Results from this study indicate that the rate of chlamydia infection (13.7%) is high in women aged 20 years or younger and that the most important risk factor is young age. These findings support recent recommendations that all women 25 years and younger are screened for C. trachomatis in pregnancy.
