Global prevalence of preterm birth among Pacific Islanders: A systematic review and meta-analysis

The epidemiology of preterm birth among Pacific Islanders is minimally understood. The purpose of this study was to estimate pooled prevalence of preterm birth among Pacific Islanders and to estimate their risk of preterm birth compared to White/European women. We searched MEDLINE, EMBASE, Web of Science Core Collection, Cochrane Library, CINAHL, Global Health, and two regional journals in March 2023. Observational studies were included if they reported preterm birth-related outcomes among Pacific Islanders. Random-effects models were used to estimate the pooled prevalence of preterm birth with 95% confidence interval (CI). Bayes meta-analysis was conducted to estimate pooled odds ratios (OR) with 95% highest posterior density intervals (HPDI). The Joanna Briggs Institute checklists were used for risk of bias assessment. We estimated preterm birth prevalence among Pacific Islanders in the United States (US, 11.8%, sample size [SS] = 209,930, 95% CI 10.8%-12.8%), the US-Affiliated Pacific Islands (USAPI, SS = 29,036, 6.7%, 95% CI 4.9%-9.0%), New Zealand (SS = 252,162, 7.7%, 95% CI 7.1%-8.3%), Australia (SS = 20,225, 6.1%, 95% CI 4.2%-8.7%), and Papua New Guinea (SS = 2,647, 7.0%, 95% CI 5.6%-8.8%). Pacific Islanders resident in the US were more likely to experience preterm birth compared to White women (OR = 1.45, 95% HPDI 1.32-1.58), but in New Zealand their risk was similar (OR = 1.00, 95% HPDI 0.83-1.16) to European women. Existing literature indicates that Pacific Islanders in the US had a higher prevalence of preterm birth and experienced health inequities. Learning from New Zealand's culturally-sensitive approach to health care provision may provide a starting point for addressing disparities. The limited number of studies identified may contribute to higher risk of bias and the heterogeneity in our estimates; more data is needed to understand the true burden of preterm birth in the Pacific region.

Preterm birth among Pacific Islanders in the United States and the US-affiliated Pacific Islands: A systematic review and meta-analysis

OBJECTIVE

To better understand the epidemiology of preterm birth among Pacific Islanders in the United States and the US-Affiliated Pacific Islands.

METHODS

Systematic searches of MEDLINE, Embase, CINAHL, PsycINFO, two nonindexed regional journals, and gray literature were conducted and finalized in September 2021. Observational studies published since January 2010 that documented preterm birth outcomes among Pacific Islanders in the United States and the US-Affiliated Pacific Islands were eligible for inclusion. Outcomes of interest included preterm birth prevalence, risk compared with white women, and risk factors for preterm birth among Pacific Islanders.

RESULTS

Fourteen of the 3183 screened articles were included in meta-analyses. Random-effects models were used for pooled estimates with 95% confidence intervals. The pooled prevalence of preterm birth among Pacific Islanders was 11.2%, 95% CI: 9.3%-13.6%. Marshallese women had the highest pooled prevalence (20.7%, 95% CI 18.6%-23.0%) among Pacific Islander subgroups. Compared with white women, Pacific Islander women had higher odds of experiencing preterm birth (OR = 1.40, 95% CI: 1.28-1.53). Four risk factors for preterm birth could be explored with the data available: hypertension, diabetes, smoking, and pre-pregnancy body mass index; hypertension and diabetes significantly increased the odds of preterm birth.

CONCLUSIONS

Existing literature suggests that United States Pacific Islanders were more likely to experience preterm birth than white women, although the pooled prevalence varied by Pacific Islander subgroup. Data support the need for disaggregation of Pacific Islanders in future research and argue for examination of subgroup-specific outcomes to address perinatal health disparities.

A global view of hypertensive disorders and diabetes mellitus during pregnancy

Two important maternal cardiometabolic disorders (CMDs), hypertensive disorders in pregnancy (HDP) (including pre-eclampsia) and gestational diabetes mellitus (GDM), result in a large disease burden for pregnant individuals worldwide. A global consensus has not been reached about the diagnostic criteria for HDP and GDM, making it challenging to assess differences in their disease burden between countries and areas. However, both diseases show an unevenly distributed disease burden for regions with a low income or middle income, or low-income and middle-income countries (LMICs), or regions with lower sociodemographic and human development indexes. In addition to many common clinical, demographic and behavioural risk factors, the development and clinical consequences of maternal CMDs are substantially influenced by the social determinants of health, such as systemic marginalization. Although progress has been occurring in the early screening and management of HDP and GDM, the accuracy and long-term effects of such screening and management programmes are still under investigation. In addition to pharmacological therapies and lifestyle modifications at the individual level, a multilevel approach in conjunction with multisector partnership should be adopted to tackle the public health issues and health inequity resulting from maternal CMDs. The current COVID-19 pandemic has disrupted health service delivery, with women with maternal CMDs being particularly vulnerable to this public health crisis.

Translating the Pelvic Organ Prolapse Score into Samoan using a modified back translation methodology

Background

Although Samoan women have a high prevalence of obesity and multiple parity which are risk factors of pelvic organ prolapse, there is no prevalence data on this condition.

Aims

Translate the Pelvic Organ Prolapse-Symptoms Score (POP-SS) from English into Samoan,

Materials and methods

Standardised methods for translating questionnaires, individual face to face audio-recorded interviews in which women completed the POP-SS using a Think Aloud method, analysis using a Framework approach.

Results

The POP-SS was successfully translated in to Samoan, an additional information leaflet was developed to support women’s understanding of what prolapse is, 14 Samoan women were recruited of which 13 were interviewed and completed the POP-SS, results of POP-SS (scores), results of think aloud, results in terms of research experience.

Conclusions

A Samoan version of the POP-SS is now available for further evaluation of its psychometric properties prior to wider use. The team continue to collaborate on their work on establishing the prevalence of prolapse whilst building local research capacity.

Supplementary Information

The online version contains supplementary material available at 10.1186/s12905-022-01676-3.

Relevance of Otago University postgraduate programmes in women's health to general practice: a case study

INTRODUCTION There are important changes in the health care needs of women presenting to general practice in New Zealand, which prompted an evaluation of postgraduate training needs of general practitioners (GPs) who care for women in the community. AIM To evaluate the perceived relevance of the curriculum of Otago University postgraduate programmes in women's health to GPs' work profile to identify any need for curricular change. This study was also performed to investigate the need for refresher courses or a Master's degree in obstetrics, gynaecology and women's health. METHODS In total, 426 GPs and GP trainees who had completed the postgraduate Certificate and Diploma programmes in women's health were invited to complete an online survey. The survey consisted of multiple-choice questions with five-point Likert scale ratings to rate the relevance of papers to general practice, and options for free-text comments. RESULTS There were 86 responses (20.2% response rate) and we analysed 73 (17.1%). Curriculum modules related to gynaecological care were rated as more relevant than obstetric and newborn care. GPs suggested more training in contraception and management of infertility, abnormal uterine bleeding and pelvic pain including procedural skills such as insertion of long-acting reversible contraceptives, implants and intrauterine devices. An interest in a refresher course was indicated by 76.6% of GPs. DISCUSSION GPs recognised the need for enhanced training in women's gynaecological care. Revision of the postgraduate women's health curriculum and development of new refresher courses will enable GPs, trainees and prospective GPs to improve their care for women in the community.

How do Pacific Island countries add up on contraception, abortion and reproductive coercion? Guidance from the Guttmacher report on investing in sexual and reproductive health

The Guttmacher-Lancet Commission report on Sexual and Reproductive Health and Rights called for the acceleration of progress to achieve SRHR that is essential for sustainable development. To integrate the essential services defined in this report into universal health coverage in the 11 sovereign nations in the Pacific, quality data is required to ensure needs are met efficiently and equitably. However, there are no comprehensive reports for Pacific Island countries that provide insight into all areas of SRHR. We collated the latest literature to identify the most up-to-date relevant data from United Nations and Guttmacher Institute reports to discern gaps in SRHR information and services relating to contraception, abortion and reproductive coercion. Investment is urgently required to strengthen health information systems for SRHR in the Pacific.

The COVID-19 Pandemic and Sexual and Reproductive Health and Rights in the Pacific

This short communication explores the challenges and ways forward for the delivery of sexual and reproductive health care in Pacific Island countries during the pandemic and the responses in relation to contraception, the management of unintended pregnancies, and gender-based violence.

The burden of infertility in New Zealand: A baseline survey of prevalence and service use

BACKGROUND

Studies in southern New Zealand indicate that up to a quarter of women experienced infertility, likely due to delay in childbearing. However, these findings may not be generalisable to the whole population.

AIMS

To assess the lifetime prevalence of infertility and evidence for disparities for New Zealand men and women in a nationally representative sample.

MATERIALS AND METHODS

In 2014/15 a general health survey with a module on sexual and reproductive health was conducted among New Zealand residents aged 16-74 years; 3792 men and 5222 women provided information on infertility.

RESULT(S)

There were 8.2% (95% CI 7.1-9.4%) of men and 12.5% (11.3-13.8%) of women who had experienced infertility; among fertility-tested women this was 15.4% (14.0-16.9%). Prevalence peaked in the 35-44 year age group (14.3% for men, 19.1% for women and 20.8% for fertility-tested women). Estimates for European, Māori and Asian ethnicities were similar. Pacific men and women had higher relative risks: 2.37 (95% CI 1.51-3.71) and 1.76 (1.27-2.44), respectively, compared with Europeans. Medical help was sought by 69.3% (95% CI 62.4-75.5%) of infertile men and 68.2% (63.1-72.9%) of women; this was significantly lower for Māori and Pacific.

CONCLUSIONS

Infertility levels for those of European ethnicity were similar to studies in southern New Zealand, and in other high-income countries. However, infertility levels were just as high for Māori, and higher for Pacific people, despite experiencing fertility at younger ages. Focusing on reducing causes of infertility other than delayed childbearing would likely contribute to addressing this health disparity.

'The horror stories put me off!': exploring women's acceptability of the Levonorgestrel IntraUterine System (LNG-IUS) for endometrial protection

INTRODUCTION There are few studies of user perceptions of the Levonorgestrel Intrauterine System (LNG-IUS; Mirena™), which now has the potential to play an important role in the treatment of women with hyperplasia or early stage endometrial cancer. There is limited evidence on how well the Mirena™ is perceived and accepted by women in this context. AIM To gain an understanding of New Zealand women's views on the use of the Mirena™ contraceptive device to inform policies in endometrial cancer prevention. METHODS An online survey platform (Qualtrics™) was disseminated over social media sites such as Facebook once a week for 3 weeks. The survey used mixed methods (closed questions, multiple choice and open-ended questions) and covered topics relating to the knowledge and use of the Mirena™ for endometrial protection. Data were collected and explored using content and thematic analysis. RESULTS In total, 89 women responded to the survey. Half (42/89) of respondents had never used a Mirena™ in their life. Most women (79/89) did not know anyone who had had endometrial cancer. The frequency of negative comments about the Mirena™ was higher than positive comments (42 and 26 respectively), largely attributed to personal or reported poor experiences with other contraceptives (including the copper intrauterine device). DISCUSSION Although health-care providers may view the Mirena™ favourably, this view was not reciprocated in this community sample.

Beyond the numbers-understanding women's experiences of accessing care for abnormal uterine bleeding (AUB): a qualitative study

OBJECTIVE

To gain a deeper understanding of women's experiences of accessing care for abnormal uterine bleeding (AUB) in order to inform future strategies to improve care pathways, including the early detection of endometrial cancer.

DESIGN

We conducted semistructured interviews with 15 women who attended their first gynaecological specialist consultation for AUB at Wellington Regional Hospital between October and December 2019. Inductive thematic analysis was used to explore experiences and barriers to seeking care.

RESULTS

The median age of the participant cohort was 45 years, with women self-identifying as New Zealand European (9/15), Māori (2/15) and Pasifika (4/15). All women had sought investigation for their AUB in primary care, for some women this was over a timeframe of many years. For all women, AUB had a significant and traumatic impact on their quality of life including their relationships and their work or education. Women described how they felt they often received inadequate care for AUB, and reported negative experiences with their general practitioner. Timely access was further compounded by feelings of embarrassment and that AUB was a taboo subject, and being able to discuss it with family, friends and their general practitioners was difficult.

CONCLUSION

Women in our cohort experienced a multitude of compounding influences that acted as barriers to them having access to appropriate and timely care. Information campaigns that create awareness around 'abnormal periods' alongside better health provider practice guidelines for AUB investigation need to be a priority.

Barriers to seeking consultation for abnormal uterine bleeding: systematic review of qualitative research

Background

Although Abnormal Uterine Bleeding (AUB) can have serious medical consequences and significantly impacts daily life, the overall trend is that most women do not seek care for these symptoms. The objective of this review was to synthesise factors impeding women’s access care for AUB.

Methods

Systematic literature review of qualitative studies (interview and focus group) regarding the lived in experiences of women with abnormal menstrual symptoms, followed by a thematic analysis of these studies. We screened CINAHL, SCOPUS, ProQuest, OVID and Pubmed for qualitative studies. Studies were assessed using the Clinical Appraisal Skills Programme checklist and thematic synthesis was used to develop themes from the findings of the studies.

Results

The review yielded 12 studies that satisfied the inclusion criteria. Three themes were developed that described barriers for women seeking care for AUB: health literacy (understanding of normal periods, role of cervical Pap smears and lack of access to appropriate information), taboo/normalisation (fear and embarrassment of symptoms, prioritising others) and health care provider (lack of accessible and trusted female GPs and poor experiences with GPs).

Conclusions

For 20 years women have consistently reported poor experiences in accessing care for AUB. The findings from our review indicate that drivers to impeding access are multiple; therefore any approaches to improve access will need to be multi-level – from comprising local sociocultural considerations to improved GP training.

Reflection on the current status of endometrial cancer in New Zealand

Incidence of endometrial cancer is increasing rapidly in the developed world and is the most common gynaecological cancer in Australia and New Zealand. In line with obesity rates, the landscape and average age of women diagnosed with endometrial cancer are changing. There is still unmet need in early diagnosis, directed treatment, management of comorbidities and prevention strategies. This opinion piece aims to reflect on the current status of endometrial cancer in New Zealand in parallel to Australia, drawing out areas for future research and discussion.

Cancer control in the Pacific: big challenges facing small island states

This Series paper describes the current state of cancer control in Pacific island countries and territories (PICTs). PICTs are diverse but face common challenges of having small, geographically dispersed, isolated populations, with restricted resources, fragile ecological and economic systems, and overburdened health services. PICTs face a triple burden of infection-related cancers, rapid transition to lifestyle-related diseases, and ageing populations; additionally, PICTs are increasingly having to respond to natural disasters associated with climate change. In the Pacific region, cancer surveillance systems are generally weaker than those in high-income countries, and patients often present at advanced cancer stage. Many PICTs are unable to provide comprehensive cancer services, with some patients receiving cancer care in other countries where resources allow. Many PICTs do not have, or have poorly developed, cancer screening, pathology, oncology, surgical, and palliative care services, although some examples of innovative cancer planning, prevention, and treatment approaches have been developed in the region. To improve cancer outcomes, we recommend prioritising regional collaborative approaches, enhancing cervical cancer prevention, improving cancer surveillance and palliative care services, and developing targeted treatment capacity in the region.

Cancer control in small island nations: from local challenges to global action

Cancer is a leading cause of death in small island nations and is forecast to increase substantially over the coming years. Governments, regional agencies, and health services of these nations face daunting challenges, including small and fragile economies, unequal distribution of resources, weak or fragmented health services, small population sizes that make sustainable workforce and service development problematic, and the unavailability of specialised cancer services to large parts of the population. Action is required to prevent large human and economic costs relating to cancer. This final Series paper highlights the challenges and opportunities for small island nations, and identifies ways in which the international community can support efforts to improve cancer control in these settings. Our recommendations focus on funding and investment opportunities to strengthen cancer-related health systems to improve sharing of technical assistance for research, surveillance, workforce, and service development, and to support small island nations with policy changes to reduce the consumption of commodities (eg, tobacco and unhealthy food products) that increase cancer risk.

Cancer management in the Pacific region: a report on innovation and good practice

Pacific island countries and territories (PICTs) face the challenge of a growing cancer burden. In response to these challenges, examples of innovative practice in cancer planning, prevention, and treatment in the region are emerging, including regionalisation and coalition building in the US-affiliated Pacific nations, a point-of-care test and treat programme for cervical cancer control in Papua New Guinea, improving the management of children with cancer in the Pacific, and surgical workforce development in the region. For each innovation, key factors leading to its success have been identified that could allow the implementation of these new developments in other PICTs or regions outside of the Pacific islands. These factors include the strengthening of partnerships within and between countries, regional collaboration within the Pacific islands (eg, the US-affiliated Pacific nations) and with other regional groupings of small island nations (eg, the Caribbean islands), a local commitment to the idea of change, and the development of PICT-specific programmes.

Dermatological conditions encountered in The Independent State of Samoa and an exploration of possible strategies to manage dermatological health-care needs in this resource-poor setting

This report adds to the limited existing literature concerning dermatoses in Samoa. Conditions encountered during a 4-day private clinic are reported. Amongst the 75 patients reviewed, eczema was the most frequent condition diagnosed. This was followed by infective dermatoses particularly pityriasis versicolor and tinea infections. Reassuringly, in 97% of cases, suitable medications were available locally.

Vitamin D activity of breast milk in women randomly assigned to vitamin D3 supplementation during pregnancy

BACKGROUND

Human milk is typically low in vitamin D activity (VDA). Whether the vitamin D content of breast milk at birth can be increased by supplementing the mother during pregnancy has not been reported to the best of our knowledge.

OBJECTIVE

We examined the effect of vitamin D supplementation during pregnancy on breast-milk VDA in the first 2 mo of lactation.

DESIGN

Breast-milk samples were obtained from women who were enrolled in a randomized, double-blinded, placebo-controlled trial of vitamin D supplementation during pregnancy. Pregnant women were enrolled at 27 wk of gestation and randomly assigned to the following 3 groups: a placebo group, a group who received one dosage of daily oral vitamin D3 (1000 IU), or a group who received 2 dosages of daily oral vitamin D3 (2000 IU). Serum 25-hydroxyvitamin D [25(OH)D] was measured at enrollment, at 36 wk of gestation, and in cord blood at birth. Study participants who were breastfeeding were invited to provide breast-milk samples for VDA measurement [concentration of vitamin D2, vitamin D3, 25(OH)D2, and 25(OH)D3] at 2 wk and 2 mo postpartum. A linear mixed model was used to compare breast-milk VDA between the 3 study groups.

RESULTS

A total of 75 women provided breast-milk samples (44 women provided breast-milk samples at both 2 wk and 2 mo postpartum). The mean (95% CI) VDA at age 2 wk was 52 IU/L (12, 217 IU/L) in the placebo group, 51 IU/L (17, 151 IU/L) in the 1000-IU group, and 74 IU/L (25, 221 IU/L) in the 2000-IU group; and at age 2 mo, the mean (95% CI) VDA was 45 IU/L (16, 124 IU/L), 43 IU/L (18, 103 IU/L), and 58 IU/L (15, 224 IU/L), respectively. There was no significant interaction in VDA between the sample-collection time and treatment (P = 0.61), but there was a difference between lower- and higher-dosage treatment groups (P = 0.04).

CONCLUSION

Maternal vitamin D supplementation during pregnancy of 2000 IU/d (compared with 1000 IU/d and with a placebo) results in a higher VDA of breast milk ≥2 mo postpartum. This trial was registered at the Australian New Zealand Clinical Trials Registry as ACTRN12610000483055.

Mapping HPV Vaccination and Cervical Cancer Screening Practice in the Pacific Region-Strengthening National and Regional Cervical Cancer Prevention

OBJECTIVE

To provide background information for strengthening cervical cancer prevention in the Pacific by mapping current human papillomavirus (HPV) vaccination and cervical cancer screening practices, as well as intent and barriers to the introduction and maintenance of national HPV vaccination programmes in the region.

MATERIALS AND METHODS

A cross-sectional questionnaire-based survey among ministry of health officials from 21 Pacific Island countries and territories (n=21).

RESULTS

Cervical cancer prevention was rated as highly important, but implementation of prevention programs were insufficient, with only two of 21 countries and territories having achieved coverage of cervical cancer screening above 40%. Ten of 21 countries and territories had included HPV vaccination in their immunization schedule, but only two countries reported coverage of HPV vaccination above 60% among the targeted population. Key barriers to the introduction and continuation of HPV vaccination were reported to be: (i) Lack of sustainable financing for HPV vaccine programs; (ii) Lack of visible government endorsement; (iii) Critical public perception of the value and safety of the HPV vaccine; and (iv) Lack of clear guidelines and policies for HPV vaccination.

CONCLUSION

Current practices to prevent cervical cancer in the Pacific Region do not match the high burden of disease from cervical cancer. A regional approach, including reducing vaccine prices by bulk purchase of vaccine, technical support for implementation of prevention programs, operational research and advocacy could strengthen political momentum for cervical cancer prevention and avoid risking the lives of many women in the Pacific.

Gestational diabetes mellitus screening, management and outcomes in the Cook Islands

AIM

To describe current practices for screening for gestational diabetes mellitus in the Cook Islands and consider the implications of alternative screening strategies.

METHODS

Eligible women had antenatal care from January 2009 to December 2012. A non-fasting 50 g glucose challenge between 24 and 28 weeks gestation (positive if 1-hour glucose greater than or equal to 7.8 mmol/L) was followed by a 75 g oral glucose tolerance test (gestational diabetes mellitus diagnosed if fasting glucose greater than or equal to 5.2 mmol/L or 2-hour glucose greater than or equal to 8.0 mmol/L; pregnancy impaired glucose tolerance if positive screen and negative diagnostic test).

RESULTS

Uptake of the screening programme rose from 49.0% to 99.6% by the end of the study period. 646 women had a glucose challenge; for 186/646 (28.8%) the challenge was positive; 183 had an oral glucose tolerance test; 89/646 (13.8%) had pregnancy impaired glucose tolerance; 94/646 (13.9%) had gestational diabetes mellitus. Median maternal weight gain was 6 kg (gestational diabetes mellitus) and 10 kg (normal glucose tolerance); caesarean section rates were 25% and 11% respectively; baby birthweights were not significantly different. 59 women with gestational diabetes mellitus had a post-natal glucose tolerance test at their 6-week check and 21 (35.6%) had diabetes confirmed.

CONCLUSION

The gestational diabetes mellitus screening programme has a high uptake and current management appears effective in reducing maternal and fetal weight gain. A proposed new screening programme is outlined.

Reduced primary care respiratory infection visits following pregnancy and infancy vitamin D supplementation: a randomised controlled trial

AIM

To determine whether vitamin D supplementation reduces primary care visits for acute respiratory infection (ARI).

METHODS

A randomised, double-blind, placebo-controlled trial was conducted in New Zealand and powered to determine the vitamin D dose needed to achieve normal vitamin D status during infancy. Healthy pregnant women, from 27 weeks' gestation to birth, and their infants, from birth to age 6 months, were assigned to placebo or one of the two dosages of daily oral vitamin D3 . Woman/infant pairs were randomised to placebo/placebo, 1000 IU/400 IU or 2000 IU/800 IU. For this ad hoc analysis, the primary care records of enrolled children were audited to age 18 months.

RESULTS

Two hundred and sixty pregnant women were randomised to placebo (n = 87), lower-dose (n = 87) or higher-dose (n = 86) vitamin D3 . In comparison with the placebo group (99%), the proportion of children making any ARI visits was smaller in the higher-dose (87%, p = 0.004), but not the lower-dose vitamin D3 group (95%, p = 0.17). The median number of ARI visits/child was less in the higher-dose vitamin D3 group from age 6-18 months (placebo 4, lower dose 3, higher dose 2.5; p = 0.048 for higher-dose vitamin D3 vs. placebo).

CONCLUSION

Vitamin D3 supplementation during pregnancy and infancy reduces primary care visits for ARI during early childhood.

Chlamydia trachomatis screening in pregnancy in New Zealand: translation of national guidelines into practice

INTRODUCTION

Chlamydia trachomatis (C. trachomatis) is a common sexually transmitted infection (STI), and routine antenatal screening to reduce the risk of vertical transmission is recommended in New Zealand (NZ).

AIM

To determine the proportion of pregnant women who have been screened for C. trachomatis in selected hospitals since the 2008 NZ Ministry of Health Chlamydia Management Guidelines were published, and to examine variation by age and ethnicity.

METHODS

Clinical audits were undertaken at four NZ hospitals, using electronic databases to determine if C. trachomatis screening had occurred.

RESULTS

Only 24%, 31%, 35% and 61% of pregnant women were screened in Tauranga (2010), Auckland (2013), Waikato (2013) and Middlemore (2011) hospitals, respectively.

DISCUSSION

Despite increases in the proportion of pregnant women screened in Auckland and Middlemore compared to pre-2008, and higher proportions of young women and Maori women screened, overall antenatal screening for C. trachomatis remains suboptimal. Several strategies are presented to support universal screening in pregnancy, as recommended by the NZ Ministry of Health.

Vitamin D during pregnancy and infancy and infant serum 25-hydroxyvitamin D concentration

OBJECTIVE

To determine the vitamin D dose necessary to achieve serum 25-hydroxyvitamin D (25(OH)D) concentration ≥ 20 ng/mL during infancy.

METHODS

A randomized, double-blind, placebo-controlled trial in New Zealand. Pregnant mothers, from 27 weeks' gestation to birth, and then their infants, from birth to age 6 months, were randomly assigned to 1 of 3 mother/infant groups: placebo/placebo, vitamin D3 1000/400 IU, or vitamin D3 2000/800 IU. Serum 25(OH)D and calcium concentrations were measured at enrollment, 36 weeks' gestation, in cord blood, and in infants at 2, 4, and 6 months of age.

RESULTS

Two-hundred-and-sixty pregnant women were randomized. At enrollment, the proportions with serum 25(OH)D ≥ 20 ng/mL for placebo, lower-dose, and higher-dose groups were 54%, 64%, and 55%, respectively. The proportion with 25(OH)D ≥ 20 ng/mL was larger in both intervention groups at 36 weeks' gestation (50%, 91%, 89%, P < .001). In comparison with placebo, the proportion of infants with 25(OH)D ≥ 20 ng/mL was larger in both intervention groups to age 4 months: cord blood (22%, 72%, 71%, P < .001), 2 months (50%, 82%, 92%, P < .001), and 4 months (66%, 87%, 87%, P = .004), but only in the higher-dose group at age 6 months (74%, 82%, 89%, P = .07; higher dose versus placebo P = .03, lower dose versus placebo P = .21).

CONCLUSIONS

Daily vitamin D supplementation during pregnancy and then infancy with 1000/400 IU or 2000/800 IU increases the proportion of infants with 25(OH)D ≥ 20 ng/mL, with the higher dose sustaining this increase for longer.

Community experience of a Pacific Immersion Programme for medical students in New Zealand

AIM

To obtain the views of the Pacific community about their involvement in a Pacific Immersion Programme, to determine the programme's viability as a resource for medical education.

METHOD

The Pacific Immersion Programme run by the Dunedin School of Medicine had four attachments (March, April, June and September) with local Pacific communities in 2011. Community focus groups were held the week immediately after each attachment. There were two focus group sessions for each attachment, one obtained the views of adults and the other of young people. Focus groups consisted of eight participants recruited through community coordinators and were facilitated by trained research assistants. Sessions were audio recorded and analysed using a thematic framework.

RESULTS

Sixty-four members of the community participated in the focus groups. Eight themes emerged from the discussions. The community agreed the Pacific Immersion Programme strengthened community cohesion through efforts to engage the students. There was shared learning and created opportunities for engagement between medical students and the community's younger generation. The Pacific families shared with the students about their health and context through storytelling, dancing and singing and cultural ceremonies. Participants hoped students achieved what they wanted from the programme and the experience was useful for their work in the future.

CONCLUSION

Community based medical education is a unique and useful approach for teaching medical students about the health of a minority community. The purpose of the paper is to highlight the impacts on participating communities. Nurturing established relationships and providing mutual benefits for both partners will ensure this opportunity will be available as a learning resource for future medical students.

Maternal perception of fetal activity and late stillbirth risk: findings from the Auckland Stillbirth Study

BACKGROUND

  Maternal perception of decreased fetal movements has been associated with adverse pregnancy outcomes, including stillbirth. Little is known about other aspects of perceived fetal activity. The objective of this study was to explore the relationship between maternal perception of fetal activity and late stillbirth (≥28 wk gestation) risk.

METHODS

  Participants were women with a singleton, late stillbirth without congenital abnormality, born between July 2006 and June 2009 in Auckland, New Zealand. Two control women with ongoing pregnancies were randomly selected at the same gestation at which the stillbirth occurred. Detailed demographic and fetal movement data were collected by way of interview in the first few weeks after the stillbirth, or at the equivalent gestation for control women.

RESULTS

  A total of 155/215 (72%) women who experienced a stillbirth and 310/429 (72%) control group women consented to participate in the study. Maternal perception of increased strength and frequency of fetal movements, fetal hiccups, and frequent vigorous fetal activity were all associated with a reduced risk of late stillbirth. In contrast, perception of decreased strength of fetal movement was associated with a more than twofold increased risk of late stillbirth (aOR: 2.37; 95% CI: 1.29-4.35). A single episode of vigorous fetal activity was associated with an almost sevenfold increase in late stillbirth risk (aOR: 6.81; 95% CI: 3.01-15.41) compared with no unusually vigorous activity.

CONCLUSIONS

  Our study suggests that maternal perception of increasing fetal activity throughout the last 3 months of pregnancy is a sign of fetal well-being, whereas perception of reduced fetal movements is associated with increased risk of late stillbirth.

Evaluation of Pacific obstetric and gynaecological ultrasound scanning capabilities, personnel, equipment and workloads

AIMS

There are no published data on the coverage, training or experience of ultrasound services in the Pacific. This study aimed to obtain information on the knowledge, experience and training of ultrasound operators and scanning equipment and workloads in the Pacific region.

METHODS

Participants for the survey were recruited by post, via the Pacific Society of Reproductive Health (PSRH) website and at the PSRH conference. Questions obtained information on ultrasound scanning capabilities, personnel, equipment and workloads in the Pacific region

RESULTS

30 respondents from 17 hospitals in 11 countries provided completed questionnaires. Close to 50% of the responses were from Fiji. The majority of respondents were sonographers or obstetricians. Lack of transvaginal probes (7/17) in some facilities limit accuracy of early pregnancy scanning. 17/17 respondents felt an advanced course would be the preferred type of course.

CONCLUSION

There is a sound basic level of ultrasound being performed in the Pacific region. A multimodal training programme, incorporating a practical hands-on course based in New Zealand, combined with CD/published materials appears to be the best method of developing more advanced skills in order to optimise antenatal care in the region.

Women's choice in the gender and ethnicity of her obstetrician and gynaecologist

OBJECTIVE

To ascertain women's preferences in the gender and ethnicity of her obstetrician or gynaecologist and to determine whether there were differences in preferences among different ethnic and age groups.

STUDY DESIGN

A simple 11-item questionnaire was placed at the antenatal and gynaecological clinics provided by South Auckland Health. The questionnaire was voluntary and 848 women completed the questionnaire over a 4-month period.

RESULTS

Half of the women preferred a woman doctor and the other half had no preference. There was a 6% increase in preference for a woman doctor where an examination was required. Of the women who preferred a female doctor, 45% would change their preference if a chaperone were present. There was no disproportionate increase in preference for a woman doctor by the patient's ethnicity or age group. Most of the women did not think the ethnicity of her doctor mattered; however, 18% preferred the ethnicity of her doctor be similar to hers. There were more European women who preferred a European doctor and fewer Maori women would prefer a Maori doctor. Of the 9% of women who did not prefer a doctor of the same ethnicity to hers, Pacific Island women were over-represented.

CONCLUSION

This is the first study of this nature in New Zealand and the findings on preference for a female doctor are similar to those from other countries. The results of the present study did not show any difference in preference by women from the ethnicities studied and by age group. The use of a chaperone where a male doctor suggests an examination will reassure nearly half of those women who preferred a female doctor. Although most women did not think the ethnicity of her doctor mattered, there were distinct differences by ethnicity with more European women preferring a European doctor and fewer Maori women preferring a Maori doctor. A qualitative study is needed to ascertain reasons for these differences in preference.

A systematic review of transvaginal ultrasonography, sonohysterography and hysteroscopy for the investigation of abnormal uterine bleeding in premenopausal women

BACKGROUND

To determine the accuracy of transvaginal ultrasonography, sonohysterography and diagnostic hysteroscopy for the investigation of abnormal uterine bleeding in premenopausal women.

DESIGN

Systematic review of common diagnostic imaging tests.

DATA SOURCES

Relevant papers were identified through electronic searching of MEDLINE (1980 to July 2001) and EMBASE (1980 to July 2001) and manual searching of a bibliography of primary and review articles.

REVIEW METHODS

Studies were selected if accuracy of transvaginal ultrasonography, sonohysterography and diagnostic hysteroscopy was compared with a reference standard and included data that could be abstracted into a two-by-two table in order to calculate sensitivity and specificity. Quality assessment and data extraction were performed by at least two independent reviewers. Diagnostic accuracy was determined by calculating positive and negative likelihood ratios for all intrauterine pathologies, submucous fibroids and endometrial hyperplasia.

RESULTS

Nineteen studies met the inclusion criteria. Statistically significant heterogeneity was present between the likelihood ratios for studies of transvaginal ultrasound. A positive test result with sonohysterography diagnosed submucous fibroids with a pooled likelihood ratio of 29.7 (17.8, 49.6). A positive test result with hysteroscopy diagnosed submucous fibroids with a pooled likelihood ratio of 29.4 (13.4, 65.3), and any intrauterine pathology with a pooled likelihood ratio of 7.7 (4.3, 13.7). A negative test result with hysteroscopy for diagnosing any intrauterine pathology had a pooled likelihood ratio of 0.07 (0.04, 0.15).

CONCLUSION

Although there was considerable variability present between the studies, all three diagnostic tests were moderately accurate in detecting intrauterine pathology. However, sonohysterography and hysteroscopy performed better than transvaginal ultrasound in detecting submucous fibroids.

Ovarian response to purified FSH in infertile women with long-standing hypogonadotrophic hypogonadism

It has previously been proposed that all anovulatory women requiring exogenous gonadotrophin therapy could be treated by purified FSH alone in the follicular phase. We have studied the ovarian response to purified FSH in 5 amenorrhoeic women with low endogenous LH production as a result of long-standing hypothalamic amenorrhoea. Follicles developed in all of the women but the rise in oestradiol was very slow. As a consequence of the HCG injection being delayed to allow the follicles to become functionally mature, too many follicles attained a preovulatory size. After the treatment was changed to more conventional preparations containing both FSH and LH, the women had improved ovarian responses and 3 of them conceived. It is clear that FSH alone will promote follicular growth but that LH is needed to stimulate follicular function. We conclude that LH does play an important role in follicular maturation and that it is a critical component of exogenous gonadotrophin therapy for women with prolonged hypogonadotrophic hypogonadism.
