Maternal age, ethnicity and gestational diabetes mellitus

BACKGROUND in Australia, and globally, rates for gestational diabetes mellitus (GDM) have risen dramatically in recent decades. This is of concern as GDM is associated with adverse pregnancy outcomes and additional health-care costs. Factors linked to increasing incidence include older maternal age and non-Caucasian ethnicity. However, as yet, there is no clear consensus on the magnitude of effect associated with these factors in combination. This study therefore investigated the effect of maternal age and country/region of birth on GDM incidence. METHODS all women who gave birth in Victoria, Australia in 2005 and 2006 (n=133,359) were included in this population-based cross-sectional study. Stratified cross-tabulations were conducted to examine the incidence of GDM by maternal age group and country/region of birth. Primiparous women were further analysed separately from parous women. The proportion of women with GDM was reported, along with the χ(2) for linear trend. FINDINGS whilst women born outside Australia constituted just 24.6% of women giving birth during the study period, they accounted for 41.4% of GDM cases. The highest GDM incidence was seen among Asian women at 11.5%, compared with Australian born women at 3.7%. There was strong evidence that women born in all regions except North America were increasingly likely to develop GDM in pregnancies at older ages (p<0.001).On examining age related GDM trends by maternal region of birth, higher rates were seen across all regions studied but were most marked among women born in Asia and the Middle East. CONCLUSIONS older maternal age and non-Australian birth increased a womans risk of developing GDM and this increase was most evident among Asian women. As GDM is associated with adverse maternal and infant outcomes, it is important to explore ways of preventing GDM, and to put in place strategies to effectively manage GDM during pregnancy and to reduce the later risk of developing type 2 diabetes. Pregnancy presents midwives with a unique opportunity to provide education and to encourage dietary and behavioural modifications as women have repeated contact with the health system during this time.

Older Maternal Age and Intervention in Labor: A Population-Based Study Comparing Older and Younger First-Time Mothers in Victoria, Australia

BACKGROUND In Australia, birth rates for women aged 35 years or more are significant and increasing and a considerable percentage are first births. This study investigated the effect of maternal age on interventions in labor and birth for primiparous women aged 35 to 44 years compared with primiparous women aged 25 to 29 years. METHODS All primiparous women who gave birth in Victoria, Australia, in 2005 and 2006 (n = 57,426) were included in this population-based cross-sectional study. Women were stratified by admission status (private/public). Main outcome measures were induction of labor, augmentation of labor, use of epidural analgesia, and method of birth. Multivariate logistic regression was used to explore the relationship between maternal age and cesarean adjusted for confounders. RESULTS Older women were more likely to give birth by cesarean section whether admitted as public or private patients. For private patients, total cesarean rates were 31.8 percent (25-29 yr), 46.0 percent (35-39 yr), and 60.0 percent (40-44 yr; p < 0.001) compared with 27.5, 41.6, and 53.4 percent for public patients (p < 0.001). Older women who experienced labor were more likely to have an instrumental vaginal birth or an emergency cesarean section than younger women. Both were more common in women admitted as private patients. Age-related trends were also seen for induction of labor and use of epidural analgesia. Rates were higher for private patients. Rates of induction were (37.8, 40.2, and 42.5%) for private patients compared with (32.1, 36.7, and 40.1%) for public patients and rates for epidural were (45.3, 49.9, and 48.1%) among private patients compared with (33.3, 38.8, and 39.3%) among public patients. CONCLUSIONS Interventions in labor and birth increased with maternal age, and this effect was seen particularly for cesarean section among women admitted privately. These findings were not fully explained by the complications we considered.

Advanced maternal age and obstetric morbidity for women giving birth in Victoria, Australia: A population‐based study

As the proportions of older women giving birth increase, there is a growing body of evidence on the increased risks of poorer maternal and perinatal outcomes for this group. However, the associations are not completely understood. This study aimed to establish the prevalence of selected maternal morbidities and examine whether advanced maternal age is associated with a higher risk of morbidity for women giving birth in Victoria.

In-Hospital Formula Supplementation of Breastfed Babies: A Population-Based Survey

BACKGROUND   In-hospital formula supplementation of breastfed newborns is commonplace despite its negative association with breastfeeding duration. Although several studies have described the use of formula supplementation, few have explored the factors that may be associated with its use. The aim of this study was to explore factors associated with in-hospital formula supplementation using data from a large Australian population-based survey. METHODS   All women who gave birth in September and October 2007 in two Australian states were mailed questionnaires 6 months after the birth. Women were asked how they fed their baby while in hospital after the birth. Multivariable logistic regression was used to explore specified a priori factors associated with in-hospital formula supplementation. RESULTS   Of 4,085 women who initiated breastfeeding, 23 percent reported their babies receiving formula supplementation. Breastfed babies had greater odds of receiving formula supplementation if their mother was primiparous (adj. OR=2.16; 95% CI: 1.76-2.66); born overseas and of non-English-speaking background (adj. OR=2.03; 95% CI: 1.56-2.64); had a body mass index more than 30 (adj. OR=2.27; 95% CI: 1.76-2.95); had an emergency cesarean section (adj. OR=1.72; 95% CI: 1.3-2.28); or the baby was admitted to a special care nursery (adj. OR=2.72; 95% CI: 2.19-3.4); had a birthweight less than 2,500 g (adj. OR=2.02; 95% CI: 1.3-3.15) or was born in a hospital not accredited with Baby-Friendly Hospital Initiative (BFHI) (adj. OR=1.53; 95% CI: 1.2-1.94). CONCLUSIONS   The number of factors associated with in-hospital formula supplementation suggests that this practice is complex. Some results, however, point to an opportunity for intervention, with the BFHI appearing to be an effective strategy for supporting exclusive breastfeeding.

Bridging the Gap: using an interrupted time series design to evaluate systems reform addressing refugee maternal and child health inequalities

BackgroundThe risk of poor maternal and perinatal outcomes in high-income countries such as Australia is greatest for those experiencing extreme social and economic disadvantage. Australian data show that women of refugee background have higher rates of stillbirth, fetal death in utero and perinatal mortality compared with Australian born women. Policy and health system responses to such inequities have been slow and poorly integrated. This protocol describes an innovative programme of quality improvement and reform in publically funded universal health services in Melbourne, Australia, that aims to address refugee maternal and child health inequalities.Methods/designA partnership of 11 organisations spanning health services, government and research is working to achieve change in the way that maternity and early childhood health services support families of refugee background. The aims of the programme are to improve access to universal health care for families of refugee background and build organisational and system capacity to address modifiable risk factors for poor maternal and child health outcomes. Quality improvement initiatives are iterative, co-designed by partners and implemented using the Plan Do Study Act framework in four maternity hospitals and two local government maternal and child health services.Bridging the Gap is designed as a multi-phase, quasi-experimental study. Evaluation methods include use of interrupted time series design to examine health service use and maternal and child health outcomes over a 3-year period of implementation. Process measures will examine refugee families’ experiences of specific initiatives and service providers’ views and experiences of innovation and change.DiscussionIt is envisaged that the Bridging the Gap program will provide essential evidence to support service and policy innovation and knowledge about what it takes to implement sustainable improvements in the way that health services support vulnerable populations, within the constraints of existing resources.

Mindfulness and perinatal mental health: A systematic review.

BACKGROUND Perinatal stress is associated with adverse maternal and infant outcomes. Mindfulness training may offer a safe and acceptable strategy to support perinatal mental health. AIM To critically appraise and synthesise the best available evidence regarding the effectiveness of mindfulness training during pregnancy to support perinatal mental health. METHODS The search for relevant studies was conducted in six electronic databases and in the grey literature. Eligible studies were assessed for methodological quality according to standardised critical appraisal instruments. Data were extracted and recorded on a pre-designed form and then entered into Review Manager. FINDINGS Nine studies were included in the data synthesis. It was not appropriate to combine the study results because of the variation in methodologies and the interventions tested. Statistically significant improvements were found in small studies of women undertaking mindfulness awareness training in one study for stress (mean difference (MD) -5.28, 95% confidence intervals (CI) -10.4 to -0.42, n=22), two for depression (for example MD -5.48, 95% CI -8.96 to -2.0, n=46) and four for anxiety (for example, MD -6.50, 95% CI -10.95 to -2.05, n=32). However the findings of this review are limited by significant methodological issues within the current research studies. CONCLUSION There is insufficient evidence from high quality research on which to base recommendations about the effectiveness of mindfulness to promote perinatal mental health. The limited positive findings support the design and conduct of adequately powered, longitudinal randomised controlled trials, with active controls.

Is place of birth associated with mode of birth? The effect of hospital on caesarean section rates in a public metropolitan health service

The effects of place of birth on birth outcomes have been examined in several studies both locally and internationally. However, none has examined the impact on caesarean section rates of different level maternity hospitals operating within the one health service. This study aimed to examine the impact of place of (Hospital level 6; 4–5 or 4) on birth outcomes in a large metropolitan health service in Victoria.

Bridging the language gap: a co-designed quality improvement project to engage professional interpreters for women duing labour

Objective The aim of the study was to improve the engagement of professional interpreters for women during labour. Methods The quality improvement initiative was co-designed by a multidisciplinary group at one Melbourne hospital and implemented in the birth suite using the plan-do-study-act framework. The initiative of offering women an interpreter early in labour was modified over cycles of implementation and scaled up based on feedback from midwives and language services data. Results The engagement of interpreters for women identified as requiring one increased from 28% (21/74) at baseline to 62% (45/72) at the 9th month of implementation. Conclusion Improving interpreter use in high-intensity hospital birth suites is possible with supportive leadership, multidisciplinary co-design and within a framework of quality improvement cycles of change. What is known about the topic? Despite Australian healthcare standards and policies stipulating the use of accredited interpreters where needed, studies indicate that services fall well short of meeting these during critical stages of childbirth. What does the paper add? Collaborative approaches to quality improvement in hospitals can significantly improve the engagement of interpreters to facilitate communication between health professionals and women with low English proficiency. What are the implications for practice? This language services initiative has potential for replication in services committed to improving effective communication between health professionals and patients.

Poorer detection rates of severe fetal growth restriction in women of likely refugee background: A case for re‐focusing pregnancy care

Severe fetal growth restriction (FGR) (< third centile) in a singleton pregnancy undelivered by 40 weeks is one of a number of Victorian Perinatal Services Performance Indicators, which aim to provide a measure of the quality and safety of maternity care. Women of refugee background have been found to have poorer perinatal outcomes compared to others and these outcomes can in part be explained by previous history. However, less access to and engagement with pregnancy care may also be contributing factors. This study examined the impact of likely refugee background on severe FGR in a singleton pregnancy undelivered by 40 weeks.
