Identifying and responding to family adversity in Australian community and primary health settings: a multi-site cross sectional study.

Background: Unaddressed family adversity has potentially modifiable, negative biopsychosocial impacts across the life course. Little is known about how Australian health and social practitioners identify and respond to family adversity in community and primary health settings. Objective: To describe, in two Australian community health services: (1) the number of adversities experienced by caregivers, (2) practitioner identification of caregivers experiencing adversity, (3) practitioner response to caregivers experiencing adversity, and (4) caregiver uptake of referrals. Methods: Survey of caregivers of children aged 0-8 years attending community health services in Victoria and New South Wales (NSW). Analysis described frequencies of caregiver self-reported: (1) experiences of adversity, (2) practitioner identification of adversity, (3) practitioner response to adversity, and (4) referral uptake. Analyses were sub-grouped by three adversity domains and site. Results: 349 caregivers (Victoria: n = 234; NSW: n = 115) completed the survey of whom 88% reported experiencing one or more family adversities. The median number of adversities was 4 (2-6). Only 43% of participants were directly asked about or discussed an adversity with a practitioner in the previous 6 months (Victoria: 30%; NSW: 68%). Among caregivers experiencing adversity, 30% received direct support (Victoria: 23%; NSW: 43%), and 14% received a referral (Victoria: 10%; NSW: 22%) for at least one adversity. Overall, 74% of caregivers accepted referrals when extended. Conclusion: The needs of Australian families experiencing high rates of adversity are not systematically identified nor responded to in community health services. This leaves significant scope for reform and enhancement of service responses to families experiencing adversity.

Pregnancy planning health information and service needs of women with chronic non-communicable conditions: a systematic review and narrative synthesis.

BACKGROUND: Preparing for pregnancy and being in the best possible health before conception improves reproductive outcomes. For women living with a chronic non-communicable disease (NCD), pregnancy planning is essential to allow optimal disease control in preparation for pregnancy. AIM: The aim was to review the literature relating to the pregnancy planning health information and service needs of women with NCDs. METHOD: The MEDLINE (Ovid), Embase (Ovid), Emcare (Ovid), PsycINFO (Ovid), CINAHL and Scopus databases were searched. Studies were included if they were published in peer-reviewed English language journals between January 2010 and June 2020 and reported on the pregnancy planning health information and service needs of women with rheumatic diseases, asthma, cystic fibrosis, depression and/or anxiety, type 1 diabetes mellitus, epilepsy, or multiple sclerosis. Risk of bias was assessed using QualSyst. The characteristics of the studies were tabulated and summarised. Key findings of the included studies were analysed thematically using an inductive approach, where the study findings determined the themes. Findings are reported in a narrative synthesis. RESULTS: The database searches yielded 8291 results, of which 4304 remained after duplicates were removed. After abstract screening 104 full-text papers were reviewed. Of these 15 met inclusion criteria and were included in analysis. The narrative synthesis of the included studies revealed six themes: 'Women with chronic conditions have unmet preconception health information needs', 'Women with chronic conditions want personalised preconception health information', 'Preferred sources of preconception health information', 'Learning from the experiences of other women', 'Improving preconception health discussions with health care professionals', and 'Women want holistic care'. These themes were consistent across all studies, highlighting the similarity of experiences and needs of women with different chronic conditions. CONCLUSION: To improve pregnancy outcomes for women living with NCDs, health care providers need to ask women of reproductive age proactively and routinely about their pregnancy intentions and provide them with personalised advice on how to avoid unplanned pregnancy and be in optimal health when they wish to conceive.

Healthcare professionals' perspective on delivering personalised and holistic care: using the Theoretical Domains Framework.

BACKGROUND: Interventions to improve personalised and holistic care delivery by healthcare professionals are more likely to be effective if they target the factors influencing specific behaviours. This study reports on the development and testing of a questionnaire to identify perspectives of healthcare professionals' personalised and holistic care behaviours based on the Theoretical Domains Framework. METHODS: The study was conducted in public health services in Victoria, Australia. The questionnaire was developed and pilot-tested with behaviour change researchers and healthcare professionals. Doctors, nurses and midwives were recruited via notices and email invitations from Safer Care Victoria's website and mailing lists of healthcare professionals and invited to completed the questionnaire online (hosted on Qualtrics). Health services administrators and allied health professionals were excluded from the study. Confirmatory factor analysis was undertaken to generate the model of best fit and group differences were tested using univariate tests. RESULTS: One hundred and four healthcare professionals from public health services in Victoria, Australia, completed the 39-item questionnaire focusing on specific personalised and holistic care behaviours. The final model consisted of 13 factors and 39 items, and CFA produced an acceptable fit, as well as adequate levels of discriminant validity and internal consistency (α = 0.60 to 0.84). Seven domains, "social influence", "motivation & goals", "environmental context and resources', "skills", 'beliefs about consequences", "behaviour regulation" and "nature of behaviour" were identified. Significant differences in the factors influencing these behaviours were found in groups with different years of experience and role seniority. These findings suggest that future interventions need to be targeted to specific groups. CONCLUSION: This study identified the specific behaviours and the factors associated with performance of personalised and holistic care among healthcare professionals. The findings suggest several interventions and policy functions may be taken to improve personalised and holistic care.

Child linear growth trajectories during the first three years of life in relation to infant iron status: a prospective cohort study in rural Vietnam.

BACKGROUND: Early childhood growth patterns have long-term consequences for health and disease. Little is known about the interplay between growth and iron status during childhood. We explored the interplay between linear growth and iron status during early childhood, by assessing child growth trajectories between 6 and 36 months (m) of age in relation to infant iron status at 6 months of age. METHODS: A cohort study of infants born to women who had previously participated in a cluster randomized controlled trial of antenatal micronutrient supplementation, conducted in rural Vietnam. The relationship between child linear growth trajectories and infant iron status (ferritin concentration) was examined using latent growth curve modeling. Primary outcomes were height for age z scores (HAZ) and growth trajectory between 6 and 36 m of age. RESULTS: A total of 1112 infants were included in the study. Mean [SD] HAZ scores decreased over time from -0·58 [0·94] at 6 m, to -0·97 [0·99] at 18 m, to -1·14 [0·89] at 36 m of age. There was a steep linear decline in the HAZ scores between 6 and 18 m of age, followed by a slower linear decline from 18 to 36 m of age. Ferritin concentration at 6 m of age was inversely associated with HAZ score at 6 m of age (-0·145, 95% CI [-0.189, -0.101]). There was no association between infant ferritin at 6 m of age and child growth trajectory between 6 and 36 m of age. CONCLUSIONS: Iron status at six months of age did not influence a child's later linear growth trajectory in this cohort of rural Vietnamese children. Longitudinal studies with repeated ferritin and height measurements are required to better delineate this relationship and inform public health interventions.

Non-corticosteroid adjuvant therapies for acute bacterial meningitis.

BACKGROUND: Acute bacterial meningitis is a bacterial infection of the membranes that surround and protect the brain, known as the meninges. The primary therapy for bacterial meningitis is antibiotics and corticosteroids. Although these therapies significantly improve outcomes, bacterial meningitis still has a high risk of death and a high risk of neurological sequelae in survivors. New adjuvant therapies are needed to further reduce the risk of death and neurological sequelae in bacterial meningitis. OBJECTIVES: To assess the effects of non-corticosteroid adjuvant pharmacological therapies for mortality, hearing loss, and other neurological sequelae in people with acute bacterial meningitis. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, and LILACS databases and ClinicalTrials.gov and WHO ICTRP trials registers up to 30 September 2021, together with reference checking, citation searching, and contact with study authors to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of any pharmacological adjuvant therapy for acute bacterial meningitis. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed and extracted data on methods, participants, interventions, and outcomes. We assessed risk of bias of studies with the Cochrane risk of bias tool and the certainty of the evidence using the GRADE approach. We presented results using risk ratios (RR) and 95% confidence intervals (CI) when meta-analysis was possible. All other results are presented in a narrative synthesis. MAIN RESULTS: We found that five different adjuvant therapies have been tested in RCTs for bacterial meningitis. These include paracetamol (3 studies, 1274 participants who were children); immunoglobulins (2 studies, 49 participants; one study included children, and the other adults); heparin (1 study, 15 participants who were adults); pentoxifylline (1 study, 57 participants who were children); and a mixture of succinic acid, inosine, nicotinamide, and riboflavin mononucleotide (1 study, 30 participants who were children). Paracetamol may make little or no difference to mortality (paracetamol 35.2% versus placebo 37.4%, 95% CI 30.3% to 40.8%; RR 0.94, 95% CI 0.81 to 1.09; 3 studies, 1274 participants; I² = 0%; low certainty evidence); hearing loss (RR 1.04, 95% CI 0.80 to 1.34; 2 studies, 901 participants; I² = 0%; low certainty evidence); neurological sequelae other than hearing loss (RR 1.56, 95% CI 0.98 to 2.50; 3 studies, 1274 participants; I² = 60%; low certainty evidence); and severe hearing loss (RR 0.96, 95% CI 0.67 to 1.36; 2 studies, 901 participants; I² = 0%; low certainty evidence). Paracetamol may lead to slightly more short-term neurological sequelae other than hearing loss (RR 1.99, 95% CI 1.40 to 2.81; 2 studies, 1096 participants; I² = 0%; low certainty evidence) and slightly more long-term neurological sequelae other than hearing loss (RR 2.32, 95% CI 1.34 to 4.04; 2 studies, 901 participants; I² = 0%; low certainty evidence). No adverse events were reported in either group in any of the paracetamol studies (very low certainty evidence). Two paracetamol studies had a low risk of bias in most domains, and one had low or unclear risk of bias in all domains. We judged the certainty of evidence to be low for mortality due to limitations in study design (unclear risk of bias in at least one domain and imprecision (high level of uncertainty in absolute effects), and low for all other outcomes due to limitations in study design (unclear risk of bias in at least one domain), and imprecision (low sample size and few events) or inconsistency in effect estimates (heterogeneity). We were not able to perform meta-analysis for any of the other adjuvant therapies due to the limited number of included studies. It is uncertain whether immunoglobulins, heparin, or pentoxifylline improves mortality outcomes due to the very low certainty of the evidence. Zero adverse events were reported for immunoglobulins (very low certainty evidence), and allergic reactions occurred at a rate of 3.3% in participants receiving a mixture of succinic acid, inosine, nicotinamide, and riboflavin mononucleotide (intervention group) (very low certainty evidence). None of our other outcomes (hearing loss, neurological sequelae other than hearing loss, severe hearing loss, and short-term or long-term neurological sequelae other than hearing loss) were reported in these studies, and all of these studies were judged to have a high risk of bias. All reported outcomes for all included adjuvant therapies, other than paracetamol, were graded as very low certainty of evidence due to limitations in study design (unclear or high risk of bias in at least four domains) and imprecision (extremely low sample size and few events). AUTHORS' CONCLUSIONS: Few adjuvant therapies for bacterial meningitis have been tested in RCTs. Paracetamol may make little or no difference to mortality, with a high level of uncertainty in the absolute effects (low certainty evidence). Paracetamol may make little or no difference to hearing loss, neurological sequelae other than hearing loss, and severe hearing loss (all low certainty evidence). Paracetamol may lead to slightly more short-term and long-term neurological sequelae other than hearing loss (both outcomes low certainty evidence). There is insufficient evidence to determine whether any of the adjuvant therapies included in this review (paracetamol, immunoglobulins, heparin, pentoxifylline, or a mixture of succinic acid, inosine, nicotinamide, and riboflavin mononucleotide) are beneficial or detrimental in acute bacterial meningitis.

Benefits and Risks of Iron Interventions in Infants in Rural Bangladesh.

BACKGROUND: Universal provision of iron supplements (drops or syrup) or multiple micronutrient powders to young children in low-to-middle-income countries where anemia is prevalent is recommended by the World Health Organization and widely implemented. The functional benefits and safety of these interventions are unclear. METHODS: We conducted a three-group, double-blind, double-dummy, individually randomized, placebo-controlled trial to assess the immediate and medium-term benefits and risks of 3 months of daily supplementation with iron syrup or iron-containing multiple micronutrient powders, as compared with placebo, in 8-month-old children in rural Bangladesh. The primary outcome was cognitive development, as assessed by the cognitive composite score on the Bayley Scales of Infant and Toddler Development, third edition, immediately after completion of the assigned 3-month regimen; scores range from 55 to 145, with higher scores indicating better cognitive performance. Secondary outcomes included the cognitive composite score at 9 months after completion of the assigned regimen; behavioral, language, and motor development, as well as growth and hematologic markers, immediately after completion and at 9 months after completion; and safety. RESULTS: We randomly assigned 3300 infants to receive iron syrup (1101 infants), multiple micronutrient powders (1099), or placebo (1100) daily. After completion of the assigned 3-month regimen, no apparent effect on the cognitive composite score was observed with iron syrup as compared with placebo (mean between-group difference in change in score from baseline, -0.30 points; 95% confidence interval [CI], -1.08 to 0.48) or with multiple micronutrient powders as compared with placebo (mean between-group difference in change in score from baseline, 0.23 points; 95% CI, -0.55 to 1.00). No apparent effect on any other developmental or growth outcome was observed immediately after completion of the assigned regimen or at 9 months after completion. At 9 months after completion of the assigned regimen, the prevalences of anemia, iron deficiency, and iron deficiency anemia increased in all three trial groups but remained lower among the children who received iron syrup or multiple micronutrient powders than among those who received placebo. The risk of serious adverse events and incidence of symptoms of infection were similar in the three trial groups. CONCLUSIONS: In this trial involving infants in Bangladesh, 3 months of daily supplementation with iron syrup or multiple micronutrient powders did not appear to have an effect on child development or other functional outcomes as compared with placebo.

Self-management factors associated with quality of life among women with endometriosis: a cross-sectional Australian survey.

STUDY QUESTION: What self-management factors are associated with quality of life among women with endometriosis? SUMMARY ANSWER: Greater self-efficacy was associated with improved physical and mental quality of life. WHAT IS KNOWN ALREADY: Women with endometriosis have an impaired quality of life compared to the general female population. However, most studies have investigated quality of life in a hospital or clinic setting rather than a community setting and the association between self-management factors and quality of life have not, to date, been investigated. STUDY DESIGN, SIZE, DURATION: A cross-sectional, population-based online survey was performed, which was advertised through women's, community and endometriosis-specific groups. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 620 women completed the survey for this study. Mental and physical quality of life was assessed using the standardized SF36v2 questionnaire. Self-management factors included self-efficacy, partners in health (active involvement in managing the condition) and performance of self-care activities. Treatment approaches included the use of hormonal treatment, pain medications and complementary therapies and whether the participant had a chronic disease management plan. Hierarchical regression analyses were used to examine whether self-management and treatment factors were associated with quality of life. MAIN RESULTS AND THE ROLE OF CHANCE: Both physical and mental quality of life were significantly lower among women with endometriosis compared to the mean scores of the general Australian female population (P < 0.001). Physical quality of life was positively associated with income sufficiency (P < 0.001) and greater self-efficacy (P < 0.001), but negatively associated with age (P < 0.001), pain severity (P < 0.001), use of prescription medications (P < 0.001), having a chronic disease management plan (P < 0.05) and number of self-care activities (P < 0.05). Mental quality of life was positively associated with being older (P < 0.001), partnered (P < 0.001), having a university education (P < 0.05), increasing self-efficacy (P < 0.001) and higher partners in health scores (P < 0.001). LIMITATIONS, REASONS FOR CAUTION: Results are derived from a cross-sectional study and can only be interpreted as associations not as causal relationships. The sample was more educated, more likely to speak English and be born in Australia than the general Australian female population of the same age, which may influence the generalizability of these results. WIDER IMPLICATIONS OF THE FINDINGS: This study investigated a knowledge gap by investigating quality of life of women with endometriosis in a large community sample. Self-efficacy was significantly associated with both physical and mental quality of life. Supporting women with endometriosis to improve self-efficacy through a structured chronic disease management programme may lead to improvements in this aspect of wellbeing.

Delays to diagnosis among people with severe mental illness in rural Vietnam, a population-based cross-sectional survey.

BACKGROUND: People with severe mental illness (SMI) living in low and middle-income countries can experience extended delays to diagnosis, which hinder access to medical treatment. The aims of this study were to describe the interval to diagnosis among these people in rural Vietnam and its associated factors. METHODS: A population-based cross-sectional study was conducted among people with SMI in two provinces in Vietnam. The delay to diagnosis was defined as the time between the first abnormal behaviour being observed by family members and the formal diagnosis of psychosis. A multilevel linear regression was used to examine the factors associated with the delay to diagnosis. RESULTS: Among 404 people with SMI from 370 households, the median delay to diagnosis was 11.5 months (IQR 0-168.0). Overall, 53.7% had a delay to diagnosis of less than one year (95% CI: 48.81-58.54). The financial burden of these people on their families was nearly USD 470/year. After adjusting for other factors at individual and household levels, living in a Northern province; older age, and having psychotic diagnosis before the implementation of the National Community Mental Health program (2003) were associated with a delay of more than twelve months to diagnosis. CONCLUSIONS: These data indicate that the implementation of a national policy for community-based care has been effective in reducing the delay to diagnosis in rural Vietnam. Therefore, there is a need for strengthening the program and mental health policies, focusing on public communication to improve mental health literacy and reduce stigma against SMI.

Self-management in condition-specific health: a systematic review of the evidence among women diagnosed with endometriosis.

BACKGROUND: Endometriosis is a chronic condition, requiring long-term care as there is no cure. Self-management is the active participation of a person in managing their chronic condition and has been associated with improved knowledge, self-efficacy, performance of self-management tasks and some aspects of health status in interventions for other chronic diseases. The aim was to review the available evidence about the impact of self-management on condition-specific health among women with endometriosis. METHODS: The Medline, PsycINFO, CinahlPlus, Web of Science and Scopus databases were searched and PRISMA guidelines were followed. Search terms were entered both as keywords and mapped to individual database subject headings. Inclusion criteria were: papers that reported investigations of any approach to self-management; among women (at least 18 years) diagnosed with endometriosis and published in English in a peer-reviewed journal. All study designs using quantitative or qualitative methods were eligible for inclusion. Two reviewers independently examined the quality of studies using standard criteria. The systematic review was registered with Prospero (CRD42016042028). RESULTS: A total of 1164 records were identified (after duplicates were removed), and 27 papers, reporting 19 studies met inclusion criteria. Two papers reported findings from RCTs of complementary therapies, seven reported survey data and 18 qualitative studies. No study had investigated all elements of self-management. Women with endometriosis utilise a range of self-care activities and complementary therapies to assist them to manage their symptoms. Women reported both positive and negative experiences with health care providers. CONCLUSIONS: There is some evidence that self-care activities, complementary therapies and positive patient-healthcare provider relationships are important components of self-management for endometriosis. Self-management among women with endometriosis is an emerging field of research and no investigations of all elements of self-management, informed by a comprehensive definition and theoretical framework are available. Health and wellbeing outcomes and barriers and facilitators to self-management for women with endometriosis require further investigation.

Feasibility and Acceptability of a Web-Based Treatment with Telephone Support for Postpartum Women With Anxiety: Randomized Controlled Trial.

BACKGROUND: Postpartum anxiety can have adverse effects on the mother and child if left untreated. Time constraints and stigma are common barriers to postpartum treatment. Web-based treatments offer potential flexibility and anonymity. What Am I Worried About (WaWa) is a self-guided treatment based on cognitive-behavioral and mindfulness principles for women experiencing postpartum anxiety. WaWa was developed in Australia and consists of 9 modules with optional weekly telephone support. WaWa was adapted to a Web-based version for use in England (Internet-based What Am I Worried About, iWaWa). OBJECTIVE: This study aimed to investigate the feasibility (engagement and usability) and acceptability (usefulness, satisfaction, and helpfulness) of iWaWa among English postpartum women with anxiety. METHODS: Postpartum (<12 months) women with mild-to-severe anxiety were recruited anonymously via social media during an 8-week period. Participants were randomized to the iWaWa treatment (8 weeks) or wait-list control group. Treatment and study feasibility and acceptability were assessed after the treatment, and anxiety symptoms were assessed at baseline, 8 weeks postrandomization, and 12 weeks postrandomization (treatment group only) using Web-based questionnaires. Semistructured telephone interviews were carried out after the treatment period for a more in-depth exploration of treatment acceptability and feasibility. RESULTS: A total of 89 eligible women were recruited through social media and randomized into the treatment (n=46) or wait-list control group (n=43). Women were predominantly Caucasian, well-educated, married, on maternity leave, first-time mothers and reported moderate levels of anxiety. Dropout rates were high, especially in the treatment group (treatment: 82%, 38/46; wait-list control: 51%, 22/43). A total of 26 women started iWaWa with only 2 women completing all 9 modules. Quantitative and qualitative data suggest iWaWa was experienced as generally useful and helpful. Participants enjoyed iWaWa's accessibility, anonymity, and weekly reminders, as well as the introduction to the principles of cognitive-behavioral therapy (CBT) and mindfulness. However, iWaWa was also experienced as not user-friendly enough, too long, and not smartphone-friendly. Parts of the content were experienced as not always relevant and appropriate. Participants felt that iWaWa could be improved by having it in a smartphone app format and by making the content more concise and inclusive of different parenting styles. CONCLUSIONS: Despite interest in iWaWa, the results suggest that both the study and iWaWa were not feasible in the current format. However, this first trial provides useful evidence about treatment format and content preferences that can inform iWaWa's future development, as well as research and development of Web-based postpartum anxiety treatments, in general, to optimize adherence.

Benefits and risks of Iron interventions in children (BRISC): protocol for a three-arm parallel-group randomised controlled field trial in Bangladesh.

INTRODUCTION: Anaemia is a major global health problem affecting about 43% of preschool children globally and 60% of 6-24-month-old children in rural Bangladesh, half of which is attributed to iron deficiency (ID). Although WHO recommends universal supplementation with iron or home fortification with iron-containing multiple micronutrient powders (MMPs) to children under 2 years, evidence for benefits of these interventions on childhood development (a key rationale for these interventions) and harms (especially infection) remains limited. This study aims to evaluate the impact of iron or MMPs supplementation compared with placebo on (a) children's development, (b) growth, (c) morbidity from infections and (d) haematological and iron indices. METHODS AND ANALYSIS: This study is a three-arm, blinded, double-dummy, parallel-group, placebo-controlled superiority trial using stratified individual block randomisation. The trial will randomise 3300 children aged 8-9 months equally to arm 1: iron syrup (12.5 mg elemental iron), placebo MMPs; arm 2: MMPs (including 12.5 mg elemental iron), placebo syrup; and arm 3: placebo syrup, placebo MNPs. Children will receive interventions for 3 months based on WHO recommendations and then be followed up for 9 months post intervention. The primary outcome is cognitive composite score measured by Bayley III. Secondary outcomes include motor and language composite score by Bayley III, behaviour rating using selected items from Wolke's rating scales and BSID-II behaviour ratings, temperament, growth, haemoglobin, anaemia and iron status, and infectious morbidity. Outcomes will be measured at baseline, at the end of 3-month intervention and after 9 months postintervention follow-up. ETHICS AND DISSEMINATION: The trial has been approved by the Ethical Review Committee of icddr,b (Dhaka, Bangladesh) and the Melbourne Health Human Research Ethics Committee (Melbourne, Australia). Results of the study will be disseminated through scientific publications, presentations at international meetings and policy briefs to key stakeholders.

Effect of low-dose versus higher-dose antenatal iron supplementation on child health outcomes at 36 months of age in Viet Nam: longitudinal follow-up of a cluster randomised controlled trial.

INTRODUCTION: Intermittent iron-folic acid supplementation (IFA) is currently recommended for pregnant women in populations where anaemia prevalence among pregnant women is <20% or if daily iron is not acceptable. The effect of providing lower doses of antenatal elemental iron through intermittent regimes on longer-term health outcomes in childhood is unclear. METHODS: A prospective cohort study conducted between May 2012 and May 2014 in Viet Nam among children of 36 months of age, born to women previously enrolled in a cluster randomised controlled trial of antenatal micronutrient supplementation (daily IFA (60 mg elemental iron) vs twice-weekly IFA (60 mg elemental iron) vs twice-weekly multiple micronutrient (MMN) supplementation (60 mg elemental iron)). Primary outcomes were height-for-age z-scores (HAZ), according to WHO growth standards and cognitive composite scores (Bayley Scales of Infant and Toddler Development, third edition) at 36 months of age. RESULTS: A total of 1017 children born to mothers enrolled in the cluster randomised trial were assessed at 36 months of age. Adjusted mean differences (MDs) in HAZ were -0.14 (95% CI -0.28 to -0.01) and -0.15 (95% CI -0.29 to -0.01) in children born to mothers who received twice-weekly IFA or MMN compared with those who received daily IFA. Children born to mothers who received twice-weekly MMN had lower composite motor scores compared with those who received daily IFA (MD -2.07, 95% CI -4.11 to -0.03). There were no differences in composite cognitive scores in the twice-weekly compared with daily regimens. CONCLUSIONS: Low-dose antenatal IFA supplementation (120 mg elemental iron per week) resulted in lower HAZ and motor composite scores in children compared with higher-dose antenatal IFA supplementation (420 mg elemental iron per week). This highlights the importance of adequate iron stores during pregnancy and the need for careful monitoring when lower-dose antenatal iron regimens are used.

Weight management during pregnancy: a qualitative study of women's and care providers' experiences and perspectives.

BACKGROUND: Obesity during pregnancy is a serious health problem for women and their children. Despite the high prevalence of high body mass index (BMI) among women of reproductive age in high-income countries, there is insufficient evidence to inform practice and policy about weight management for women with high BMI who are pregnant. The aim of this project was to describe women's and midwives' experiences and perspectives of care for weight management during pregnancy in Melbourne, Australia. METHODS: A qualitative study. Semi-structured interviews were conducted with pregnant women and midwives. Transcripts were analysed thematically. RESULTS: A total of 17 women and 2 midwives were interviewed. Five themes were identified: 1. Reluctance to and difficulties discussing weight and its implications; 2. Barriers to providing appropriate pregnancy care for women with high BMI; 3. Inconsistent weighing practices; 4. Beliefs about the causes of obesity; and 5. Opportunities to assist women to manage their weight. Although most women were satisfied with the pregnancy care they had received, both women and midwives expressed concerns about effective weight management during pregnancy. These included constraints on discussing weight, difficulties accessing appropriate resources and additional support from other health care providers, and inconsistent weighing practices. CONCLUSIONS: The findings suggest that women with high BMI would benefit from additional information and support about weight management prior to conception, during pregnancy, and postnatally.

Exclusive breast feeding in early infancy reduces the risk of inpatient admission for diarrhea and suspected pneumonia in rural Vietnam: a prospective cohort study.

BACKGROUND: Acute respiratory infections and diarrhea remain the leading causes of infant morbidity and mortality, with a high burden of both pneumonia and diarrhea in South-East Asia. The aim of the study was to determine antenatal and early infant predictive factors for severe morbidity episodes during the first 6 months of life in Ha Nam province, Vietnam. METHODS: A prospective cohort study of 1049 infants, born to women who had previously participated in a cluster randomized controlled trial of antenatal micronutrient supplementation in rural Vietnam, was undertaken between 28th September 2010 and 8th Jan 2012. Infants were followed until 6 months of age, and the outcome measure was inpatient admission for suspected pneumonia or diarrheal illness during the first 6 months of life. Risk factors were assessed using univariable logistic regression and multiple logistic regression. RESULTS: Of the 1049 infants seen at 6 months of age, 8.8 % required inpatient admission for suspected pneumonia and 4 % of infants required inpatient admission for diarrheal illness. One third of infants (32.8 %) were exclusively breast fed at 6 weeks of age. Exclusive breast feeding at 6 weeks of age significantly reduced the odds of inpatient admission for suspected pneumonia (Odds Ratio (OR) 0.39, 95 % Confidence Interval (CI) 0.20 to 0.75) and diarrheal illness (OR 0.37, 95 % CI 0.15 to 0.88). CONCLUSIONS: Exclusive breast feeding in early infancy reduces the risk of severe illness from diarrhea and suspected pneumonia. Public health programs to reduce the burden of inpatient admission from diarrheal and respiratory illness in rural Vietnam should address barriers to exclusive breast feeding.

Antenatal Iron Supplementation Regimens for Pregnant Women in Rural Vietnam and Subsequent Haemoglobin Concentration and Anaemia among Their Infants.

BACKGROUND: Little evidence about the effects of antenatal iron supplementation on infant anaemia is available. The aim was to compare effects on six-month-old infants' Haemoglobin (Hb) concentration and anaemia of daily iron-folic acid (IFA), twice-weekly IFA with or without other micronutrients (MMN) and usual antenatal care in rural Vietnam. METHODS AND FINDINGS: Secondary data analysis from: a prospective population-based observational study (OS) which examined effects of antenatal psychosocial factors, anaemia and iron deficiency on infant development and health; and a three-arm cluster randomised trial (CRT) of different antenatal iron supplementation regimens. In the OS 497 women (<20 weeks gestation) from 50 randomly-selected communes participated, and in the CRT 1,258 pregnant women (<16 weeks gestation) in 104 communes were allocated randomly to trial arms. The main outcome was six-month-old infant Hb concentration. Baseline data included women's socio-demographic characteristics, reproductive health, Hb and serum ferritin. Mean differences in infant Hb and odds ratios of infant anaemia between CRT arms and OS were calculated by multivariable regression models, controlling for baseline differences and clustering, using robust standard errors. Infant anaemia prevalence was 68.6% in the OS, 47.2% daily IFA, 53.5% weekly IFA, and 50.3% MMN conditions. After adjustment, mean infant haemoglobin levels in daily IFA (mean difference = 0.95 g/dL; 95%CI 0.7-11.18); weekly IFA (0.91; 95%CI 0.69-1.12) and MMN (1.04; 95%CI 0.8-1.27) were higher than in the OS. After adjustment there were lower odds ratios of anaemia among infants in the daily IFA (OR = 0.31; 95% CI 0.22-0.43), weekly IFA (0.38; 95%CI 0.26-0.54) and MMN (0.33; 95%CI 0.23-0.48) groups than in the OS. CONCLUSIONS: Infant anaemia is a public health problem in Vietnam and other resource-constrained countries. All supplementation regimens could have clinically significant benefits for Hb and reduce anaemia risk among six-month-old infants. Universal provision of free intermittent iron supplements is warranted.

Antenatal and early infant predictors of postnatal growth in rural Vietnam: a prospective cohort study.

OBJECTIVE: To determine which antenatal and early-life factors were associated with infant postnatal growth in a resource-poor setting in Vietnam. STUDY DESIGN: Prospective longitudinal study following infants (n=1046) born to women who had previously participated in a cluster randomised trial of micronutrient supplementation (ANZCTR:12610000944033), Ha Nam province, Vietnam. Antenatal and early infant factors were assessed for association with the primary outcome of infant length-for-age z scores at 6 months of age using multivariable linear regression and structural equation modelling. RESULTS: Mean length-for-age z score was -0.58 (SD 0.94) and stunting prevalence was 6.4%. Using structural equation modelling, we highlighted the role of infant birth weight as a predictor of infant growth in the first 6 months of life and demonstrated that maternal body mass index (estimated coefficient of 45.6 g/kg/m(2); 95% CI 34.2 to 57.1), weight gain during pregnancy (21.4 g/kg; 95% CI 12.6 to 30.1) and maternal ferritin concentration at 32 weeks' gestation (-41.5 g per twofold increase in ferritin; 95% CI -78 to -5.0) were indirectly associated with infant length-for-age z scores at 6 months of age via birth weight. A direct association between 25-(OH) vitamin D concentration in late pregnancy and infant length-for-age z scores (estimated coefficient of -0.06 per 20 nmol/L; 95% CI -0.11 to -0.01) was observed. CONCLUSIONS: Maternal nutritional status is an important predictor of early infant growth. Elevated antenatal ferritin levels were associated with suboptimal infant growth in this setting, suggesting caution with iron supplementation in populations with low rates of iron deficiency.

Postnatal growth outcomes and influence of maternal gestational weight gain: a prospective cohort study in rural Vietnam.

BACKGROUND: Suboptimal weight gain during pregnancy may result in adverse outcomes for both the mother and child, including increased risk of pre-eclampsia and gestational diabetes, delivery of low birth weight and small-for-gestational age (SGA) infants, and preterm delivery. The objectives of this study were to identify maternal predictors of rate of weight gain in pregnancy, and to evaluate the association of gestational weight gain with infant postnatal growth outcomes. METHODS: We conducted a prospective cohort study of infants born to women who had previously participated in a double-blind cluster randomized controlled trial of antenatal micronutrient supplementation, in Ha Nam province, Vietnam. Pregnant women (n = 1258) were seen at enrolment and 32 weeks gestation, and infants (n = 965) were followed until 6 months of age. Primary outcome was infant anthropometric indicators at 6 months of age (weight for age, length for age, weight for height z scores), and infant weight gain velocity during the first 6 months of life. RESULTS: Low body mass index (<18.5 kg/m2) was present in 26% of women, and rate of gestational weight gain was 0.4 kg per week [SD 0.12]. Rate of weight gain during pregnancy was significantly associated with infant weight-for-age (MD 1.13, 95% CI 0.58 to 1.68), length-for-age (MD 1.11, 95% CI 0.66 to 1.55), weight-for-length z scores (MD 0.63, 95% CI 0.07 to 1.19), and infant weight gain velocity during the first 6 months of life (MD 93.6 g per month, 95% CI 8.2 to 179.0). CONCLUSIONS: Rate of gestational weight gain is predictive of postnatal growth at six months of age in this setting. Public health programs should be targeted towards improving body mass index and weight gain in pregnant women in rural Vietnam.

Maternal vitamin D status and infant outcomes in rural Vietnam: a prospective cohort study.

OBJECTIVE: Vitamin D deficiency affects 1 billion people globally. It has an important role in bone homeostasis, brain development and modulation of the immune system and yet the impact of antenatal vitamin D deficiency on infant outcomes is poorly understood. We assessed the association of 25- hydroxyvitamin D levels (25-OHD) in late pregnancy and early infant growth and developmental outcomes in rural Vietnam. DESIGN AND METHODS: A prospective cohort study of 960 women who had previously participated in a double-blind cluster randomized controlled trial of antenatal micronutrient supplementation in rural Vietnam was undertaken. Maternal 25-OHD concentration was measured at 32 weeks gestation, and infants were followed until 6 months of age. Main outcome measures were cognitive, motor, socio-emotional and language scores using the Bayley Scales of Infant Development, 3rd edition, and infant length-for-age z scores at 6 months of age. RESULTS: 60% (582/960) of women had 25-OHD levels <75 nmol/L at 32 weeks gestation. Infants born to women with 25-OHD deficiency (<37.5 nmol/L) had reduced developmental language scores compared to those born to women who were vitamin D replete (≥75 nmol/L) (Mean Difference (MD) -3.48, 95% Confidence Interval (CI) -5.67 to -1.28). For every 25 nmol increase in 25-OHD concentration in late pregnancy, infant length-for-age z scores at 6 months of age decreased by 0.08 (95% CI -0.15 to -0.02). CONCLUSIONS: Low maternal 25- hydroxyvitamin D levels during late pregnancy are of concern in rural Vietnam, and are associated with reduced language developmental outcomes at 6 months of age. Our findings strengthen the evidence for giving vitamin D supplementation during pregnancy.

Psychological and social factors associated with late pregnancy iron deficiency anaemia in rural Viet Nam: a population-based prospective study.

OBJECTIVES: The aim of this study was to examine the relationships between psychological and social factors and late pregnancy IDA among pregnant women in rural Viet Nam. METHODS: Pregnant women from 50 randomly-selected communes within Ha Nam province were recruited and assessed at 12 - 20 weeks gestation (Wave 1, W1). They were followed up in the last trimester (Wave 2, W2). IDA was defined as Haemoglobin < 11 g/dL and serum ferritin < 15 ng/mL. Symptoms of Common Mental Disorders (CMD) were assessed by the Edinburgh Postnatal Depression Scale-Vietnam (EPDS-V). Persistent antenatal CMD was defined as having an EPDS-V score ≥ 4 in both W1 and W2. Hypothesis models were tested by Structural Equation Modeling analyses. RESULTS: A total of 378 women provided complete data at both W1 and W2. The incidence risk of IDA in the third trimester was 13.2% (95% confidence interval (CI): 9.8-16.7). Persistent CMD was found in 16.9% (95% CI: 13.1-20.7) pregnant women and predicted by intimate partner violence, fear of other family members, experience of childhood abuse, coincidental life adversity, and having a preference for the sex of the baby. There was a significant pathway from persistent CMD to IDA in late pregnancy via the length of time that iron supplements had been taken. Receiving advice to take iron supplements and higher household wealth index were indirectly related to lower risk of late pregnancy IDA. Early pregnancy IDA and being multi-parous also contributed to late pregnancy IDA. CONCLUSIONS: Antenatal IDA and CMD are prevalent public health problems among women in Viet Nam. The link between them suggests that while direct recommendations to use iron supplements are important, the social factors associated with common mental disorders should be addressed in antenatal care in order to improve the health of pregnant women and their infants.

The effect of intermittent antenatal iron supplementation on maternal and infant outcomes in rural Viet Nam: a cluster randomised trial.

BACKGROUND: Anemia affects over 500 million women, and in pregnancy is associated with impaired maternal and infant outcomes. Intermittent antenatal iron supplementation is an attractive alternative to daily dosing; however, the impact of this strategy on infant outcomes remains unclear. We compared the effect of intermittent antenatal iron supplementation with daily iron supplementation on maternal and infant outcomes in rural Viet Nam. METHODS AND FINDINGS: This cluster randomised trial was conducted in Ha Nam province, Viet Nam. 1,258 pregnant women (< 16 wk gestation) in 104 communes were assigned to daily iron-folic acid (IFA), twice weekly IFA, or twice weekly multiple micronutrient (MMN) supplementation. Primary outcome was birth weight. Mean birth weight was 3,148 g (standard deviation 416). There was no difference in the birth weights of infants of women receiving twice weekly IFA compared to daily IFA (mean difference [MD] 28 g; 95% CI -22 to 78), or twice weekly MMN compared to daily IFA (MD -36.8 g; 95% CI -82 to 8.2). At 32 wk gestation, maternal ferritin was lower in women receiving twice weekly IFA compared to daily IFA (geometric mean ratio 0.73; 95% CI 0.67 to 0.80), and in women receiving twice weekly MMN compared to daily IFA (geometric mean ratio 0.62; 95% CI 0.57 to 0.68), but there was no difference in hemoglobin levels. Infants of mothers who received twice weekly IFA had higher cognitive scores at 6 mo of age compared to those who received daily IFA (MD 1.89; 95% CI 0.23 to 3.56). CONCLUSIONS: Twice weekly antenatal IFA or MMN did not produce a clinically important difference in birth weight, when compared to daily IFA supplementation. The significant improvement in infant cognitive outcomes at 6 mo of age following twice weekly antenatal IFA requires further exploration, and provides additional support for the use of intermittent, rather than daily, antenatal IFA in populations with low rates of iron deficiency.
