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

Short birth/pregnancy interval and its association with adverse maternal outcomes in Asia Pacific region: A systematic review and meta-analysis

BACKGROUND

Short interpregnancy/birth interval (SIBI) may be associated with greater risks of adverse pregnancy outcomes. This study aimed to synthesise the literature on the association between SIBI and adverse maternal outcomes in Asia-Pacific.

METHODS

Five databases were searched for studies published between 2000 and 2023. Studies were eligible if they reported an association between SIBI and adverse maternal outcomes (e.g., anaemia). Studies that met the WHO's definition of SIBI were included in the meta-analysis. The key findings were then summarised through qualitative synthesis and meta-analyses.

RESULTS

26 articles that examined the association between SIBI and adverse maternal outcomes and were included in the narrative synthesis. Eight studies examined anaemia, two examined antenatal or postnatal depression, three assessed gestational diabetes mellitus, and four studies examined preeclampsia. A significant association between SIBI and anaemia was reported, indicating an 181 % increase in anaemia with a SIBI (OR of 2.81;95 % CI: 1.30-4.31) compared to an optimal birth interval. There was a significant association between SIBI and gestational diabetes mellitus (OR of 0.68; 95 % CI: 0.65-0.71), antenatal or postnatal depression (OR of 2.36; 95 % CI: 1.76, 3.01) but no significant associations were found for preeclampsia (OR of 0.74; 95 % CI: 0.48-1.01).

CONCLUSION

Our review highlights that SIBI places women at an increased risk of adverse maternal outcomes compared to optimal birth interval. This indicates the importance of addressing short birth interval through effective contraception as a key maternal health intervention to reduce adverse maternal outcomes.

Expanding access to postpartum contraception

PURPOSE OF REVIEW

Women are particularly vulnerable to unintended pregnancy in the 12 months following a birth. Improving access to postpartum contraception within maternity settings can prevent unintended and closely spaced births, improving the health of mother and child. This review will summarize the recent research in postpartum contraception (PPC), building on existing knowledge and developments in this field.

RECENT FINDINGS

Current models of postpartum contraceptive provision may not adequately meet women's needs. The COVID-19 pandemic led to changes in postpartum contraceptive provision, with an increasing emphasis placed on maternity services. Antenatal contraceptive discussion is associated with increased postpartum contraceptive planning and uptake of methods after birth. Digital health interventions may be a useful tool to support information about contraception. The most effective long-acting reversible contraceptive (LARC) methods, such as the intrauterine device (IUD) and implant, can be challenging to provide in the maternity setting because of availability of trained providers. Postpartum IUD insertion remains relatively under-utilized, despite evidence supporting its safety, efficacy and cost-effectiveness.

SUMMARY

Antenatal information needs to be partnered with access to the full range of methods immediately after birth to reduce barriers to PPC uptake. Training and education of maternity providers is central to successful implementation of PPC services.

Postpartum contraception in Australia: opportunities for increasing access in the primary care setting

In Australia, 20% of pregnancies occur within the first year after birth and most are unintended. Both unintended pregnancies and short interpregnancy intervals (<12-18months) can have adverse effects on maternal, infant, and child health. Access to postpartum contraception reduces the risk of unintended pregnancies and short interpregnancy intervals, and supports women in pregnancy planning and birth spacing. In this forum article, we describe how postpartum contraception is currently provided in Australia and highlight opportunities for improving access in the primary care setting.

Short birth interval prevalence, determinants and effects on maternal and child health outcomes in Asia-Pacific region: a systematic review and meta-analysis protocol

BACKGROUND

Short birth interval (SBI) has been linked to an increased risk of adverse maternal, perinatal, infant and child health outcomes. However, the prevalence and maternal and child health impacts of SBI in the Asia-Pacific region have not been well understood. This study aims to identify and summarise the existing evidence on SBI including its definition, measurement prevalence, determinants and association with adverse maternal and child health outcomes in the Asia-Pacific region.

METHODS

Five databases (MEDLINE, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Maternity and Infant Care, and Web of Science (WoS)) will be systematically searched from September 2000 up to May 2023. Data will be extracted, charted, synthesised and summarised based on the outcomes measured, and where appropriate, meta-analysis will be performed. The risk of bias will be assessed using Joanna Briggs Institute quality appraisal. Grading of Recommendation Assessment, Development and Evaluation framework will be used to evaluate the quality of cumulative evidence from the included studies.

ETHICS AND DISSEMINATION

This review does not require ethics approval. Findings will be disseminated through peer-reviewed publications, policy briefs and conference presentations.

PROSPERO REGISTRATION NUMBER

A protocol will be registered on PROSPERO for each separate outcome before performing the review.Cite Now.

Understanding women's views of and preferences for accessing postpartum contraception: a qualitative evidence synthesis

BACKGROUND

Nearly half of women experience unintended pregnancies. These are associated with increased risk of poor maternal physical and psychosocial health outcomes. Many pregnancies in the first year postpartum are unintended, further increasing risks of poor outcomes and complications. We undertook a qualitative evidence synthesis to evaluate qualitative research on women's views and preferences for accessing postpartum contraception, and identify evidence gaps and opportunities for postpartum contraception provision.

METHODS

Five databases were searched to identify relevant qualitative studies. Included studies focused on views of, and preferences for, accessing postpartum contraception for women of reproductive age in high-income countries.

RESULTS

Of 1854 studies identified, 28 full texts were assessed and 19 studies included. These were critically appraised using Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) and analysed using thematic synthesis. Included studies indicated the majority of women desire postpartum contraception, but face a range of financial, health system and personal barriers. Women felt unclear about the ideal interpregnancy interval (IPI) and the rationale for this. Women preferred contraceptive counselling at varying times both antenatally and postnatally, and commonly preferred to receive contraception in the immediate postpartum period before hospital discharge. Women commonly saw their obstetrician or general practitioner for contraceptive counselling, but welcomed midwifery involvement.

CONCLUSIONS

Most women were interested in postpartum contraception and pregnancy spacing, but felt unclear about the optimal IPI, highlighting the need for further education and support around this issue. Contraceptive counselling was viewed as valuable antenatally and postnatally, and by varying maternal health providers, as was the provision of immediate postpartum contraception.

Improving Access to and Quality of Postpartum Contraception Provision

Sexual activity and fertility can resume shortly after childbirth, but there are barriers to contraceptive access in the postpartum period. Unintended pregnancy and short interpregnancy intervals (of less than one year) can increase the risk of obstetric and neonatal complications. The antenatal period presents an opportunity to discuss contraceptive options, many of which can be safely initiated immediately after childbirth. Successful delivery of a postpartum contraception program requires an adequate number of maternity staff trained to provide the full range of methods.

Birth Spacing and Health and Socioeconomic Outcomes Across the Life Course: Evidence From the Utah Population Database

The relationship between birth interval length and child outcomes has received increased attention in recent years, but few studies have examined offspring outcomes across the life course in North America. We use data from the Utah Population Database to examine the relationship between birth intervals and short- and long-term outcomes: preterm birth, low birth weight (LBW), infant mortality, college degree attainment, occupational status, and adult mortality. Using linear regression, linear probability models, and survival analysis, we compare results from models with and without sibling comparisons. Children born after a birth interval of 9-12 months have a higher probability of LBW, preterm birth, and infant mortality both with and without sibling comparisons; longer intervals are associated with a lower probability of these outcomes. Short intervals before the birth of the next youngest sibling are also associated with LBW, preterm birth, and infant mortality both with and without sibling comparisons. This pattern raises concerns that the sibling comparison models do not fully adjust for within-family factors predicting both spacing and perinatal outcomes. In sibling comparison analyses considering long-term outcomes, not even the very shortest birth intervals are negatively associated with educational or occupational outcomes or with long-term mortality. These findings suggest that extremely short birth intervals may increase the probability of poor perinatal outcomes but that any such disadvantages disappear over the extended life course.

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.

Knowledge and Attitude Towards Short Birth Interval among Rural Women who Gave Birth in the Last Three Years at Dembecha District, Northwest Ethiopia, 2019

Background

A woman can have fewer children when intervals between consecutive births are optimal. This has great importance for the well-being of women, pregnancy outcomes, and the long-term health of children under the age of five. We can save 2millon of the 11 million deaths of children under the age of five per year by avoiding short birth intervals. It is affected by the knowledge and attitude of women, particularly rural women, who had a high fertility rate. To our deep review, this is the first study done in Ethiopia. Hence, this study aimed to assess knowledge and attitude towards short birth intervals and associated factors among rural women who gave birth in the last three years at Dembecha district, northwest Ethiopia.

Method

A community-based cross-sectional study was conducted from September 20 to October 20, 2019. A cluster sampling technique was employed to select the study participants and data were collected using a pre-tested, semi-structured, interviewer-administered questionnaire. Bivariable and multivariable logistic regression model was fitted to identify factors associated with knowledge and attitude towards short birth interval. The level of significant association was declared using the adjusted odds ratio (AOR) with 95% confidence interval (CI) and a p-value of <0.05.

Result

From the total study participants, 66.4% (95% CI: 63.0–70.0) had good knowledge and 45.9% (95% CI: 42.3–49.8) had a positive attitude towards short birth intervals. In multivariable logistic regression: marital status, antenatal care follow-up, maternal occupation, and wealth status were significantly associated with knowledge. In addition, antenatal care follow-up and maternal occupation were significantly associated with attitude.

Conclusion

Majority of the participants had poor knowledge and a positive attitude towards short birth intervals. Hence, interventions should be done to optimize women's knowledge and attitude towards short birth intervals by enhancing antenatal care utilization.

Feasibility, acceptability and sustainability of postpartum contraceptive implant provision by midwives in NSW public hospitals

BACKGROUND

Repeat pregnancy in the first year after a birth is common. Many of these conceptions are unintended and may be prevented by providing access to contraception in the immediate postpartum period. Midwives in the hospital setting could potentially play a greater role in improving postnatal contraception information and provision.

AIM

We sought to implement and examine the success of a program training hospital-based midwives in immediate postpartum implant insertion.

METHODS

This mixed methods study in two hospitals in New South Wales sought to explore the feasibility, acceptability and sustainability of a program that provided competency-based implant insertion training for midwives. The study documented training completion, implant insertion numbers and experience, and conducted end of study interviews with midwives and stakeholders.

FINDINGS

Twenty-seven midwives undertook training and inserted 265 implants during the study period. Interviews with 13 midwives and 11 stakeholders concluded the program to be feasible and acceptable with midwives reporting high satisfaction from their involvement. All interviewees felt that midwives were well placed to insert implants, and reported that challenges around workload and opportunities for practice were generally manageable. It was recognised that sustainability of the program would require supportive policy and regular insertion opportunities.

CONCLUSIONS

Midwives successfully upskilled in implant insertions and there was widespread support for the program with expectations it would be sustained. Provision of contraceptive information and implant insertion by midwives in the immediate postpartum period is likely to increase contraceptive choice and access for women and contribute to reducing rapid repeat pregnancies.

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.

Contraception provision in the postpartum period: Knowledge, views and practices of midwives

BACKGROUND

Women are susceptible to unintended pregnancies in the first year after giving birth, particularly as consideration of contraception may be a low priority during this time. Discussing and providing contraception before women leave hospital after giving birth may prevent rapid repeat pregnancy and its associated risks. Midwives are well placed to assist with contraceptive decision-making and provision; however, this is not routinely undertaken by midwives in the Australian hospital setting and little is known regarding their views and experiences in relation to contraception.

METHODS

An anonymous survey was conducted with midwives at two urban hospitals in New South Wales to better understand their contraceptive knowledge, views and practices regarding midwifery-led contraception provision in the postpartum period.

FINDINGS

The survey was completed by 128 midwives. Most agreed that information about contraception provided in the postpartum period is valuable to women, although their knowledge about different methods was variable. The majority (88%) believed that midwives have a role in providing contraceptive information, and 79% reported currently providing contraceptive counselling. However, only 14% had received formal training in this area.

CONCLUSION

Findings demonstrate that most midwives provide some contraception information and believe this is an important part of a midwife's role. Yet most have not undertaken formal training in contraception. Additional research is needed to explore the content and quality of midwives' contraception discussions with women. Training midwives in contraceptive counselling would ensure women receive accurate information about available options. Upskilling midwives in contraception provision may increase postpartum uptake and reduce rapid repeat pregnancies.
