Adherence to management guidelines for growth faltering and anaemia in remote dwelling Australian Aboriginal infants and barriers to health service delivery

Are Pregnant Women Who Are Living with Overweight or Obesity at Greater Risk of Developing Iron Deficiency/Anaemia?

Low-grade inflammation is often present in people living with obesity. Inflammation can impact iron uptake and metabolism through elevation of hepcidin levels. Obesity is a major public health issue globally, with pregnant women often affected by the condition. Maternal obesity is associated with increased pregnancy risks including iron deficiency (ID) and iron-deficiency anaemia (IDA)-conditions already highly prevalent in pregnant women and their newborns. This comprehensive review assesses whether the inflammatory state induced by obesity could contribute to an increased incidence of ID/IDA in pregnant women and their children. We discuss the challenges in accurate measurement of iron status in the presence of inflammation, and available iron repletion strategies and their effectiveness in pregnant women living with obesity. We suggest that pre-pregnancy obesity and overweight/obese pregnancies carry a greater risk of ID/IDA for the mother during pregnancy and postpartum period, as well as for the baby. We propose iron status and weight gain during pregnancy should be monitored more closely in women who are living with overweight or obesity.

The iron content of healthy diets for one day for breastfed babies and young children

AIMS

Early childhood anaemia due to iron deficiency is widespread in remote communities across northern Australia. Current recommendations for healthy food to complement breastfeeding at age 6 to 23 months include iron-rich and iron-enriched foods. An electronic nutrient analysis was undertaken to assess the iron content of hypothetical healthy diets for breastfed babies and young children aged 6 to 23 months in Australia, in comparison with their estimated requirements.

METHODS

Hypothetical diets for 1 day were developed that were consistent with the Foundation Diets for breastfed infants 6 to 12 months and for toddlers 13 to 23 months. Nutrient content was derived using the Australian Food Composition database in FoodWorks 10. The iron content of these two diets were compared with Estimated Average Requirements (EARs) and Recommended Dietary Intakes (RDIs) for iron for infants aged 7 to 12 months and children aged 1 to 3 years.

RESULTS

The iron content of the hypothetical diet for breastfed infants aged 6 to 12 months (5.8 mg) was less than the EAR (7 mg, 83%) and the RDI (11 mg, 53%). For young breastfed children aged 13 to 23 months, the iron content of the hypothetical diet was 4.4 mg; above the EAR (4 mg, 110%) but less than RDI (9 mg, 49%).

CONCLUSIONS

Breastfeeding has health and neurodevelopmental benefits for infants and young children that are particularly important in remote Australia where food insecurity and poor nutrition compromise health and wellbeing. Adequate iron intake is also important for neurodevelopment in early life but healthy diets for breastfed babies and young children may have insufficient iron content to meet requirements. The upcoming revision of the Australian Dietary Guidelines provides an opportunity to consider this issue.

How Barunga Aboriginal community implemented and sustained an anaemia program - A case study evaluation

ISSUE ADDRESSED

Anaemia persists as a public health issue in many Aboriginal communities despite having standard practice guidelines. This case study reveals how Barunga Aboriginal Community in the Northern Territory (NT), Australia, implemented an Anaemia Program (1998-2016) which contributed to low anaemia prevalence in children aged under 5 years.

METHODS

This retrospective qualitative case study used purposive sampling to describe the Anaemia Program and factors influencing its implementation. Themes were developed from convergence of three data sources: interviews, program observation and document review. Data were inductively analysed by an Aboriginal and non-Aboriginal researcher and themes were validated by Barunga community health practitioners and compared to practice guidelines and implementation literature.

RESULTS

Health practitioners reported that the Anaemia Program contributed to a marked reduction in childhood anaemia prevalence over time. This was supported by available prevalence data. The locally adapted Anaemia Program was unique in the NT with a novel approach to community supplementation for anaemia prevention in addition to anaemia treatment. Supportive implementation influences included: Aboriginal leadership and the use of culturally supportive processes which reinforced the development of trust and strong relationships facilitating community acceptance of the Program. Routine, opportunistic and flexible health care practice, a holistic approach and a stable, skilled and experienced team sustained program implementation.

CONCLUSIONS

The holistic and successful Barunga Anaemia Program is supported by evidence and guidelines for treating and preventing childhood anaemia. The contextualisation of these guidelines aligned with the literature on effective Aboriginal primary health care implementation. SO WHAT?: This Anaemia Program provides a model for implementation of evidence-informed guidelines in an Aboriginal primary health care setting.

Customised approaches to vocational education can dramatically improve completion rates of Australian Aboriginal students

Objective Completion rates in vocational education are typically poor for Aboriginal students (<30%). A scholarship program was designed for Australian Aboriginal students using five enablers of success previously identified for Aboriginal preregistration tertiary nursing students. The purpose of this study was to evaluate whether the five enablers contributed to the success of Aboriginal students in vocational education and whether there were any other enablers. Methods Semistructured interviews were conducted with two groups of Aboriginal students in Certificate III and IV Dental Assisting and Certificate IV in Allied Health Assistance, and their teaching and support staff. The data were initially coded inductively. Initial codes were then categorised according to the five enablers identified to contribute to the success of Bachelor of Nursing students. New categories were created for data not assigned to the enablers. Results Twenty students (64.5% of the cohort) and six staff (75%) consented to participate. The five enablers were perceived to have contributed to the success of the scholarship recipients and two additional enablers were identified. A completion rate of 96.8% was achieved by the scholarship recipients (30 completions of 31 enrolments). Conclusions In contrast with the state average, a completion rate of 96.8% was achieved using seven enablers in this study. To improve completion rates for Aboriginal students, vocational education programs need to be customised to cultural, family and community context. The seven enablers in this study should be subject to a larger study to inform policy, funding, design and delivery of vocational training for Aboriginal students. What is known about the topic? It is well established in the literature that Aboriginal students have poorer educational outcomes than other students. What does this paper add? This paper validates five previously identified enablers to improve outcomes for Aboriginal students and an additional two for vocational education. These enablers may also be applicable to other types of education. What are the implications for practitioners? Practitioners can use the enablers in this study to design and implement vocational education programs and improve educational outcomes for Aboriginal students.

Early childhood anaemia more than doubles the risk of developmental vulnerability at school-age among Aboriginal and Torres Strait Islander children of remote Far North Queensland: Findings of a retrospective cohort study

AIMS

Early childhood anaemia, usually attributed to iron deficiency, is associated with persistent detrimental effects on child development. This study investigates the association of anaemia between age six and 23 months with indicators of childhood development at school-age among children of remote Aboriginal and Torres Strait Islander communities of Far North Queensland.

METHODS

The triennial Australian Early Development Census (AEDC) encompasses five domains of early childhood development-physical health and wellbeing, social competence, emotional maturity, language and cognitive skills (school-based), communication skills and general knowledge. AEDC 2012 and 2015 assessments were linked with health information for children and their mothers from remote Aboriginal and Torres Strait Islander communities of Far North Queensland.

RESULTS

AEDC assessments were available for 250 children who had measurements of haemoglobin recorded at age 6 to 23 months. More children who had had early childhood anaemia (n = 66/143, 46.2%, [37.9%, 54.4%]) were developmentally vulnerable on two or more domains compared to those who had not been anaemic (n = 25/107, 23.4% [15.2%, 31.5%], P < .001). Multivariable analysis confirmed that early childhood anaemia more than doubled the risk of developmental vulnerability (OR 2.2 [1.1, 4.3] P = .020) at school age.

CONCLUSIONS

Early childhood anaemia is a risk factor for developmental vulnerability at school-age in this setting. Interventions combining nutrition promotion and multi-micronutrient food fortification, are effective in prevention of early childhood anaemia. Such interventions could also improve early childhood development and subsequent educational achievement.

Anaemia in early childhood among Aboriginal and Torres Strait Islander children of Far North Queensland: a retrospective cohort study

OBJECTIVE

Early childhood anaemia affects health and neurodevelopment. This study describes anaemia among Aboriginal and Torres Strait Islander children of Far North Queensland.

METHODS

This retrospective cohort study used health information for children born between 2006 and 2010 and their mothers. We describe the incidence of early childhood anaemia and compare characteristics of children and mothers where the child had anaemia with characteristics of children and mothers where the child did not have anaemia using bivariate and multivariable analysis, by complete case (CC) and with multiple imputed (MI) data.

RESULTS

Among these (n=708) Aboriginal and Torres Strait Islander children of Far North Queensland, 61.3% (95%CI 57.7%, 64.9%) became anaemic between the ages of six and 23 months. Multivariable analysis showed a lower incidence of anaemia among girls (CC/MI p<0.001) and among children of Torres Strait Islander mothers or both Aboriginal and Torres Strait Islander mothers (CC/MI p<0.001) compared to children of Aboriginal mothers. A higher incidence of anaemia was seen among children of mothers with parity three or more (CC/MI p<0.001); children born by caesarean section (CC/MI p<0.001); and children with rapid early growth (CC/MI p<0.001).

CONCLUSION

Early childhood anaemia is common among Aboriginal and Torres Strait Islander children of Far North Queensland. Poor nutrition, particularly iron deficiency, and frequent infections are likely causes. Implications for public health: Prevention of early childhood anaemia in 'Close the Gap' initiatives would benefit the Aboriginal and Torres Strait Islander children of Far North Queensland - and elsewhere in northern Australia.

Anemia in disadvantaged children aged under five years; quality of care in primary practice

Background

Anemia rates are over 60% in disadvantaged children yet there is little information about the quality of anemia care for disadvantaged children.

Methods

Our primary objective was to assess the burden and quality of anemia care for disadvantaged children and to determine how this varied by age and geographic location. We implemented a cross-sectional study using clinical audit data from 2287 Indigenous children aged 6–59 months attending 109 primary health care centers between 2012 and 2014. Data were analysed using multivariable regression models.

Results

Children aged 6–11 months (164, 41.9%) were less likely to receive anemia care than children aged 12–59 months (963, 56.5%) (adjusted odds ratio [aOR] 0.48, CI 0.35, 0.65). Proportion of children receiving anemia care ranged from 10.2% (92) (advice about ‘food security’) to 72.8% (728) (nutrition advice). 70.2% of children had a hemoglobin measurement in the last 12 months. Non-remote area families (115, 38.2) were less likely to receive anemia care compared to remote families (1012, 56.4%) (aOR 0.34, CI 0.15, 0.74). 57% (111) aged 6–11 months were diagnosed with anemia compared to 42.8% (163) aged 12–23 months and 22.4% (201) aged 24–59 months. 49% (48.5%, 219) of children with anemia received follow up.

Conclusions

The burden of anemia and quality of care for disadvantaged Indigenous children was concerning across all remote and urban locations assessed in this study. Improved services are needed for children aged 6–11 months, who are particularly at risk.

Linking 'data silos' to investigate anaemia among Aboriginal and Torres Strait Islander mothers and children in Far North Queensland

OBJECTIVE

Data collection 'silos' can be linked for health research. Anaemia in early childhood is a long-recognised health issue in remote Aboriginal communities of the Northern Territory and Western Australia, but information is lacking for Queensland. The objective of this work was to compile existing information from health and education data collections to investigate anaemia among Aboriginal and Torres Strait Islander mothers and their children in Far North Queensland.

METHODS

Data mapping identified four health data collections and one education data collection holding relevant information. Data Custodians' approval was secured for release of linked de-identified information.

RESULTS

Approval processes and preparation of the dataset for release took 23 months. Birth information was obtained for 2,205 mother-child pairs where the Aboriginal and/or Torres Strait Islander child was born in Far North Queensland between 2006 and 2010. Pathology information from before/during pregnancy was obtained for 2,126 mothers (96.4%), growth and haemoglobin information for 982 children (44.5%), and childhood development indicators at school entry for 963 children (43.7%).

CONCLUSION

Linking existing information 'silos' enables research into key public health issues. Implications for public health: Information linkage is particularly valuable in respect of vulnerable populations including rural and remote Aboriginal and Torres Strait Islander peoples.

Quality of social and emotional wellbeing services for families of young Indigenous children attending primary care centers; a cross sectional analysis

BACKGROUND

The quality of social and emotional wellbeing services for Indigenous families of young children is not known, in many settings especially services provided by primary care centers.

METHODS

Our primary objective was to assess delivery of social and emotional wellbeing services to the families of young (3-11 months) and older (12-59 months) Indigenous children attending primary care centers. Our secondary objective was to assess if delivery differed by geographic location. Two thousand four hundred sixty-six client files from 109 primary care centers across Australia from 2012 to 2014 were analysed using logistic regression and generalised estimating equations.

RESULTS

The proportion of families receiving social and emotional wellbeing services ranged from 10.6% (102) (food security) to 74.7% (1216) (assessment of parent child interaction). Seventy one percent (71%, 126) of families received follow up care. Families of children aged 3-11 months (39.5%, 225) were more likely to receive social and emotional wellbeing services (advice about domestic environment, social support, housing condition, child stimulation) than families of children aged 12-59 months (30.0%, 487) (adjusted odds ratio [aOR] 1.68 95% CI 1.33 to 2.13). Remote area families (32.6%, 622) received similar services to rural (29.4%, 68) and urban families (44.0%, 22) (aOR 0.64 95% CI 0.29, 1.44).

CONCLUSIONS

The families of young Indigenous children appear to receive priority for social and emotional wellbeing care in Australian primary care centers, however many Indigenous families are not receiving services. Improvement in resourcing and support of social and emotional wellbeing services in primary care centers is needed.

Understanding the structure and processes of primary health care for young indigenous children

ABSTRACT INTRODUCTION Primary health care organisations need to continuously reform to more effectively address current health challenges, particularly for vulnerable populations. There is growing evidence that optimal health service structures are essential for producing positive outcomes. AIM To determine if there is an association between process of care indicators (PoCIs) for important young indigenous child health and social issues and: (i) primary health-care service and child characteristics; and (ii) organisational health service structures. METHODS This was a cross-sectional study of 1554 clinical child health audits and associated system assessments from 74 primary care services from 2012 to 2014. Composite PoCIs were developed for social and emotional wellbeing, child neurodevelopment and anaemia. Crude and adjusted logistic regression models were fitted, clustering for health services. Odds ratios and 95% confidence intervals were derived. RESULTS Overall, 32.0% (449) of records had a social and emotional wellbeing PoCI, 56.6% (791) had an anaemia PoCI and 49.3% (430) had a child neurodevelopment PoCI. Children aged 12–23 months were significantly more likely to receive all PoCIs compared to children aged 24–59 months. For every one point increase in assessment scores for team structure and function (aOR 1.14, 95% CI 1.01–1.27) and care planning (aOR 1.14, 95% CI 1.01–1.29) items, there was a 14% greater odds of a child having an anaemia PoCI. Social and emotional wellbeing and child neurodevelopment PoCIs were not associated with system assessment scores. DISCUSSION Ensuring young indigenous children aged 24–59 months are receiving quality care for important social and health indicators is a priority. Processes of care and organisational systems in primary care services are important for the optimal management of anaemia in indigenous children.

Risk factors for preterm, low birthweight and small for gestational age births among Aboriginal women from remote communities in Northern Australia

OBJECTIVE

To identify the risk factors for preterm birth, low birthweight and small for gestational age babies among remote-dwelling Aboriginal women.

METHODS

The study included 713 singleton births from two large remote Aboriginal communities in Northern Territory, Australia in 2004-2006 (retrospective cohort) and 2009-2011 (prospective cohort). Demographic, pregnancy characteristics, labour and birth outcomes were described. Multivariate logistic regression analysis was conducted and adjusted odds ratios were reported.

RESULTS

The preterm birth rate was 19.4%, low birthweight rate was 17.4% and small for gestational age rate was 16.3%. Risk factors for preterm birth were teenage motherhood, previous preterm birth, smoker status not recorded, inadequate antenatal visits, having pregnancy-induced hypertension, antepartum haemorrhage or placental complications. After adjusting for gender and birth gestation, the only significant risk factor for low birthweight was first time mother. The only significant risk factor for small for gestational age baby was women having their first baby.

CONCLUSIONS

Rates of these events are high and have changed little over time. Some risk factors are modifiable and treatable but need early, high quality, culturally responsive women centred care delivered in the remote communities themselves. A different approach is recommended.

The quality of health services provided to remote dwelling aboriginal infants in the top end of northern Australia following health system changes: a qualitative analysis

Background

In Australia the health outcomes of remote dwelling Aboriginal infants are comparable to infants in developing countries. This research investigates service quality, from the clinicians’ perspective and as observed and recorded by the researcher, in two large Aboriginal communities in the Top End of northern Australia following health system changes.

Methods

Data were collected from semi-structured interviews with 25 clinicians providing or managing child health services in the two study sites. Thirty hours of participant observation was undertaken in the ‘baby-rooms’ at the two remote health centres between June and December 2012. The interview and observational data, as well as field notes were integrated and analysed thematically to explore clinicians’ perspectives of service delivery to infants in the remote health centres.

Results

A range of factors affecting the quality of care, mostly identified before health system changes were instigated, persisted. These factors included ineffective service delivery, inadequate staffing and culturally unsafe practices. The six themes identified in the data: ‘very adhoc’, ‘swallowed by acute’, ‘going under’, ‘a flux’, ‘a huge barrier’ and ‘them and us’ illustrate how these factors continue, and when combined portray a ‘very chaotic system’.

Conclusion

Service providers perceived service provision and quality to be inadequate, despite health system changes. Further work is urgently needed to improve the quality, cultural responsiveness and effectiveness of services to this population.

Anaemia in school-aged children in an Australian Indigenous community

OBJECTIVE

Indigenous Australians have poorer health outcomes compared to the non-Indigenous population. Malnutrition, and subsequently iron-deficiency anaemia, impairs childhood development. The aim of this study was to identify the prevalence of anaemia in school-aged children of an Australian Indigenous community and evaluate the effectiveness of treatment.

DESIGN

A retrospective cohort study.

SETTING

A Northern Territory Indigenous community.

PARTICIPANTS

Two hundred and one school-age students (5-15 years old) undergoing annual school screening.

MAIN OUTCOME MEASURES

Presence of anaemia. Anaemic and non-anaemic students were compared to determine any differences in age, gender, BMI and past history of anaemia. The response to treatment was analysed using initial and repeat haemoglobin results.

RESULTS

Altogether, 201 students were screened with 105 (52%) classified as anaemic. No significant association was found between anaemic students and age, gender, BMI or prior history of anaemia. After treatment, the mean rise in haemoglobin was 13% (95% CI 11-15) at the 4-week interval. Age (P = 0.17), gender (P = 0.53) and weight (P = 0.14) were not significantly associated with treatment efficacy. Only 11 students (17%) were still anaemic after treatment.

DISCUSSION

Anaemia in Indigenous Australian school-aged children is a major public health issue. The prevalence of anaemia in this population is 52% and many times higher than that of the general Australian population. As per current guidelines, the recommended treatment is effective in over 80% at the 4-week interval. Community wide interventions are required to combat this alarming issue.

Reduced middle ear infection with non-typeable Haemophilus influenzae, but not Streptococcus pneumoniae, after transition to 10-valent pneumococcal non-typeable H. influenzae protein D conjugate vaccine

Background

In October 2009, 7-valent pneumococcal conjugate vaccine (PCV7: Prevenar^TM Pfizer) was replaced in the Northern Territory childhood vaccination schedule by 10-valent pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10; Synflorix™ GlaxoSmithKline Vaccines). This analysis aims to determine whether the reduced prevalence of suppurative otitis media measured in the PHiD-CV10 era was associated with changes in nasopharyngeal (NP) carriage and middle ear discharge (ED) microbiology in vaccinated Indigenous children.

Methods

Swabs of the NP and ED were collected in remote Indigenous communities between September 2008 and December 2012. Swabs were cultured using standardised methods for otitis media pathogens. Children less than 3 years of age and having received a primary course of 2 or more doses of one PCV formulation and not more than one dose of another PCV formulation were included in the primary analysis; children with non-mixed single formulation PCV schedules were also compared.

Results

NP swabs were obtained from 421 of 444 (95 %) children in the PCV7 group and 443 of 451 (98 %) children in the PHiD-CV10 group. Non-mixed PCV schedules were received by 333 (79 %) and 315 (71 %) children, respectively. Pneumococcal (Spn) NP carriage was 76 % and 82 %, and non-typeable Haemophilus influenzae (NTHi) carriage was 68 % and 73 %, respectively. ED was obtained from 60 children (85 perforations) in the PCV7 group and from 47 children (59 perforations) in the PHiD-CV10 group. Data from bilateral perforations were combined. Spn was cultured from 25 % and 18 %, respectively, and NTHi was cultured from 61 % and 34 % respectively (p = 0.008).

Conclusions

The observed reduction in the prevalence of suppurative OM in this population was not associated with reduced NP carriage of OM pathogens. The prevalence of NTHi-infected ED was lower in PHiD-CV10 vaccinated children compared to PCV7 vaccinated children. Changes in clinical severity may be explained by the action of PHiD-CV10 on NTHi infection in the middle ear. Randomised controlled trials are needed to answer this question.

Standardising and assessing digital images for use in clinical trials: a practical, reproducible method that blinds the assessor to treatment allocation

With the increasing availability of high quality digital cameras that are easily operated by the non-professional photographer, the utility of using digital images to assess endpoints in clinical research of skin lesions has growing acceptance. However, rigorous protocols and description of experiences for digital image collection and assessment are not readily available, particularly for research conducted in remote settings. We describe the development and evaluation of a protocol for digital image collection by the non-professional photographer in a remote setting research trial, together with a novel methodology for assessment of clinical outcomes by an expert panel blinded to treatment allocation.

Improving Aboriginal maternal and infant health services in the 'Top End' of Australia; synthesis of the findings of a health services research program aimed at engaging stakeholders, developing research capacity and embedding change

Background

Health services research is a well-articulated research methodology and can be a powerful vehicle to implement sustainable health service reform. This paper presents a summary of a five-year collaborative program between stakeholders and researchers that led to sustainable improvements in the maternity services for remote-dwelling Aboriginal women and their infants in the Top End (TE) of Australia.

Methods

A mixed-methods health services research program of work was designed, using a participatory approach. The study area consisted of two large remote Aboriginal communities in the Top End of Australia and the hospital in the regional centre (RC) that provided birth and tertiary care for these communities. The stakeholders included consumers, midwives, doctors, nurses, Aboriginal Health Workers (AHW), managers, policy makers and support staff. Data were sourced from: hospital and health centre records; perinatal data sets and costing data sets; observations of maternal and infant health service delivery and parenting styles; formal and informal interviews with providers and women and focus groups. Studies examined: indicator sets that identify best care, the impact of quality of care and remoteness on health outcomes, discrepancies in the birth counts in a range of different data sets and ethnographic studies of ‘out of hospital’ or health centre birth and parenting. A new model of maternity care was introduced by the health service aiming to improve care following the findings of our research. Some of these improvements introduced during the five-year research program of research were evaluated.

Results

Cost effective improvements were made to the acceptability, quality and outcomes of maternity care. However, our synthesis identified system-wide problems that still account for poor quality of infant services, specifically, unacceptable standards of infant care and parent support, no apparent relationship between volume and acuity of presentations and staff numbers with the required skills for providing care for infants, and an ‘outpatient’ model of care. Services were also characterised by absent Aboriginal leadership and inadequate coordination between remote and tertiary services that is essential to improve quality of care and reduce ‘system-introduced’ risk.

Conclusion

Evidence-informed redesign of maternity services and delivery of care has improved clinical effectiveness and quality for women. However, more work is needed to address substandard care provided for infants and their parents.
