Growth of aboriginal infants in the first year of life in remote communities in north-west Australia

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.

Ethnic differences in lung function in Israeli children

BACKGROUND

The population of Israel consists of immigrants from many different countries. It is not known whether a single nomogram can be used for spirometric values of children of different ethnic descent.

METHODS

Spirometry was performed in 753 second or third generation Israeli children (7-14 years) of different ethnic groups. Both parents of 503 of the children were of the same ethnic background. Subjects were allocated to six ethnic groups (European, Iraqi, North African, Indian, Yemenite, and Georgian).

RESULTS

Standing height contributed most to the prediction of spirometric values (forced expiratory volume in one second, forced vital capacity), whereas sitting height did not contribute further. Statistical analysis showed significant ethnic differences. The Georgians had higher spirometric values for FEV1 than all the other ethnic groups, and higher FVC values than those of the Yemenite, North African, and Indian groups. FVC was lower among the Indian than all other groups.

CONCLUSION

Differences in normal spirometric values were found among second or third generation Israeli children of different ethnic origins. European, North African, Iraqi, and Yemenite children could be characterised by single equation, whereas children of Georgian and Indian descent needed different predicting equations.

Maternal and environmental factors associated with infections and undernutrition in young Australian aboriginal children

Forty-eight Aboriginal infants in remote communities in north-west Australia were studied monthly from birth to 2 years. Birthweight and growth were positively associated with maternal health during pregnancy, regular antenatal supervision and lack of drinking alcohol or smoking tobacco as well as with personal and family hygiene. Impaired growth was associated with families which had more expensive consumer goods such as televisions, air conditioners, video cassette recorders and cassette tape players. Most children had impaired growth or frank failure to thrive which was associated with high rates of infections, particularly of the respiratory and gastro-intestinal tracts, and high rates of hospitalization.

Growth of remote Australian aborigines from birth to two years

Lengths and weights have been measured every month from birth to two years of age in 48 Aboriginal children born into six remote communities in the Kimberley region in the far north of Western Australia. Birthweights, on average, were slightly less than international reference values but growth rates in the first 3 months of life exceeded those reference values. However, between 3 and 6 months of age rates of weight gain and linear growth fell below those expected at that age and after 9 months of age Aboriginal infants were lighter than reference values and remained so throughout the first two years of life. By 2 years of age the Kimberley children were more than 1 kg lighter and 4.5 cm (boys) and 3.6 cm (girls) shorter than the international reference values. Monthly means and standard deviations for weight and length velocities are given. Environmental factors, particularly infections and inadequate nutrition, are important contributors to impaired growth in Aboriginal infants and young children.
