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

Toddlers may be getting enough iron in long day-care services after all

BACKGROUND

Previous research has suggested that toddlers are not provided with adequate dietary iron in long-day care (LDC) services. However, the iron bioavailability provided is unknown. The present study aimed to investigate the amount and bioavailability of iron provided to toddlers aged 2-3 years at LDC services.

METHODS

A cross-sectional audit was conducted using a 2-day weighed food record of 30 LDC services. Iron provision (not child intake) in LDC services across Perth, Australia was compared with the estimated average requirements (EAR) and LDC services provision guidelines (50% of EAR = 2 mg/day based on a 14% bioavailability factor). Bioavailability was estimated per mealtime using haem and non-haem iron, ascorbic acid, animal protein, calcium, soy, eggs and phytates using two pre-existing algorithms (by A. P. Rickard and colleagues and H. Hallberg and H. Hulten).

RESULTS

Median iron supplied (2.52 mg/day, interquartile range [IQR] = 2.43-3.17) was above the 50% of EAR of 2.0 mg/day (p < 0.001). Median bioavailable iron was 0.6 mg/day (IQR = 0.54-0.8) using the method of Rickard et al. and 0.51 mg/day (IQR = 0.43, 0.76 using that of Hallberg and Hulthen). The top three foods contributing to iron provision were bread, breakfast cereals and beef.

CONCLUSIONS

Our results suggest that LDC services in Perth are meeting the minimum recommendation of provision of 50% of the iron EAR, and also that toddlers are provided with sufficient bioavailable iron. Future strategies should focus on promoting food combinations to maintain the iron bioavailability in meals currently served at LDC services.

Prevalence and Risk Factors of Anaemia among Orang Asli Children in Malaysia: A Scoping Review

BACKGROUND

Anaemia continues to be a global public health burden affecting all age groups, particularly children. Indigenous people, including the Orang Asli (OA) population in Malaysia, are at risk of anaemia due to the vast disparities in social determinants of health in their population compared to the non-indigenous population.

OBJECTIVES

This review aimed to identify the prevalence and risk factors of anaemia among OA children in Malaysia and analyse the knowledge gaps.

METHODS

A systematic search was conducted in PubMed, Cochrane Library, Scopus and Google Scholar databases. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) guidelines.

RESULTS

This review identified six studies involving the participation of OA children from eight subtribes residing in Peninsular Malaysia. The overall prevalence of anaemia among OA children ranged from 21.6 to 80.0%, with iron deficiency anaemia prevalence at 34.0%. The risk factors of anaemia among OA children reported from one study in this review were being younger than ten years old children (AOR 2.11 (95% CI 1.23, 3.63)) and moderate to heavy Ascaris infections (AOR 2.05 (95% CI 1.12, 3.76)). There was no data from OA children from certain age groups and subtribes. Additionally, there is a paucity of data on risk factors for anaemia among OA children from the currently available evidence.

CONCLUSION

The prevalence of anaemia among OA children poses a moderate to severe public health concern. Therefore, more comprehensive studies in the future are needed to address the gaps identified in this review, primarily regarding anaemia risk factors. This data would encourage policymakers in devising effective national prevention strategies to improve morbidity and mortality among OA children in the future.

Factors Associated With Anemia Among Orang Asli Children Aged Two to Six Years in Negeri Sembilan, Malaysia

Background Anemia is a global public health problem that needs urgent attention, especially in early childhood. Young children living in remote indigenous communities are vulnerable to anemia. This study aimed to determine factors associated with anemia among children of the Orang Asli (OA) community, aged two to six years old. Methods A cross-sectional study was conducted among 269 OA children, together with their biological non-pregnant mothers. Their mothers were interviewed using a structured questionnaire to gather information on sociodemographic characteristics, sanitation facility and personal hygiene, food security, and dietary diversity. Anthropometric and biochemical assessments were measured using standard protocols. Results One in five of the OA children was anemic (21.2%) and had a low birth weight (20.4%). About 27.7% of the children were underweight, 35.2 % were stunted, 6.1% were wasted, and 5.7% were overweight. One-third of them (35.0%) had parasitic infections and almost all were food-insecure (96.3%). As for the mothers, more than one-third of them were anemic (39.0%), 58.9% had abdominal obesity, and 61.8% were overweight and obese. Parasitic infections (adjusted OR (AOR)=2.49, 95%CI=1.23-5.06), not wearing shoes outside the house (AOR=2.95, 95%CI=1.39-6.27), and mothers with anemia (AOR=2.62, 95%CI=1.30-5.28) were associated with increased risk of anemia among OA children. Conclusion Preventing maternal anemia and strengthening knowledge on sanitation and hygiene could be incorporated into nutrition intervention programs to address anemia issues among OA children.

Anemia Prevalence and Anthropometric Status of Indigenous Women and Young Children in Rural Botswana: The San People

In Botswana, there is limited data available on the health and nutritional status of the San People (also known as the Basarwa or Bushmen), an Indigenous minority group primarily living in the Ghanzi District. Our aim in this study was to assess anemia prevalence among and anthropometric indices of women and young children in Ghanzi District through a cross-sectional survey. We recruited 367 mother-child pairs (women 15-49 years and children 6-59 months) in nine randomly selected areas. A capillary blood sample was collected, and weight and height were measured. Hemoglobin (Hb) concentration was measured with use of a hemoglobinometer (HemoCue, AB), as per global recommendations. Overall, adjusted anemia prevalence was 12% in non-pregnant women (Hb < 120 g/L), 26% in pregnant women (Hb < 110 g/L), and 42% in children (Hb < 110 g/L), but it varied widely depending on whether or not the controversial factor of ethnicity was adjusted for (range of 6-26%, 22-30%, and 35-68% prevalence, respectively). Thirty-nine percent (n = 133/344) of non-pregnant women and 52% (n = 12/23) of pregnant women were underweight (BMI < 18.5 kg/m2). In children aged 6-23 months, 41% were underweight (weight-for-age z-score < -2 SD), 13% were wasted (weight-for-height z-score < -2 SD), and 65% were stunted (height-for-age z-score < -2 SD); in children aged 24-59 months, 57% were underweight, 13% were wasted, and 66% were stunted. Fifty-six percent (n = 205/367) of women self-reported smoking in any form (rolled cigarettes or snuffing). The high prevalence of smoking among women, underweight status among pregnant women, and anemia, stunting, and wasting among children is of the highest concern for public health and should be addressed in future health and nutrition programming.

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.

Anaemia prevalence and determinants in under 5 years children: findings of a cross-sectional population-based study in Sudan

Background

Early childhood is an age at risk of anaemia and its deleterious consequences. In Sudan, there is limited evidence on the prevalence and determinant of anaemia in under-five children. This study was conducted in Sudan to assess the prevalence of anaemia in children and to identify its determinants.

Methods

We conducted a household survey involving children aged 6 months to 5 years in November 2016. A representative population was sampled across rural, urban and camps settlements across 18 states in Sudan. We used a pre-designed questionnaire data collection. Haemoglobin (Hb) level and malaria infection were checked. In this cross-sectional study, we dichotomized the outcome variable and performed logistic regression analyses.

Results

A total of 3094 children under 5 years enrolled in the study, 1566 (50.6%) of them were female and 690 (22.3%) of them were under 2 years old. Anaemia prevalence in the whole cohort (6 months - < 5 years) was 49.4% and the mean haemoglobin concentration was 108.1 (standard deviation (SD): 15.4) g/L. The prevalence in younger (6 months - < 2 years) children (61.9%) was higher than in older (2 - < 5 years) children (45.6%) (p < 0.001). Severe anaemia (Hb < 70 g/L) prevalence in the whole population was 1.6%. Age (Odds ratio (OR) 2.25, 95% confidence interval (95%CI) 1.75–2.90, p < 0.001), type of place of residence (OR 0.37, 95%CI 0.18–0.74, p = 0.005), maternal anaemia (OR 1.74, 95%CI 1.39–2.17, p < 0.001), and malaria infection (OR 2.82, 95%CI 1.56–5.11, p < 0.001) were the identified predictors of anaemia in the whole cohort. In younger children, only the economic class was an anaemia predictor, with a lower anaemia risk among the rich wealth class (OR 2.70, 95%CI 1.29–5.62, p = 0.008). However, in older children, three anaemia predictors were identified. These are maternal anaemia (OR 1.79, 95%CI 1.40–2.28, < 0.001), malaria infection (OR 2.77, 95%CI 1.48–5.21, p = 0.002), and type of residency (where camps’ residents were less likely affected with anaemia than rural children (OR 0.38, 95%CI 0.17–0.87, p = 0.022)).

Conclusions

About half of the under-5 children in Sudan are anaemic, with worse prevalence in younger children. Efforts targeted at improving socio-economic status, decreasing maternal anaemia and childhood malaria infection may mitigate this alarming trend.

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.
