Growth of remote Australian aborigines from birth to two years

Environmental health conditions in remote and rural aboriginal communities in western Australia

During 1994-1995 environmental health conditions of about 13,760 persons in 155 remote and rural Aboriginal communities in 20 local shires in Western Australia (WA) were surveyed. A semiquantitative questionnaire sought data about the communities and their services, including water supplies, power, sanitation and disposal of solid and liquid waste; a separate section dealt with conditions of individual dwellings. Data were recorded by experienced local workers. Thirty-five communities considered to have the worst conditions were evaluated on-site by a team of senior personnel in mid-1995. Environmental health problems were prevalent and often serious: over one-third of the communities had water supply or sanitation problems and 70 per cent had housing problems, with overcrowding and substandard housing being commonplace. Thirty-six per cent had difficulties with waste water disposal, 37 per cent had no rubbish disposal, and in others, the methods of disposal were often inadequate; pests were problems in 44 per cent of communities and the hygiene and maintenance of communal toilets was unacceptable in 25 per cent. Seventy-two per cent had no on-site environmental health worker and 44 per cent had no on-site or visiting medical, nursing or health worker personnel. An action plan was developed and the highest-priority communities were targeted in a program of major works (for example, housing, drainage and sewerage) and minor works, which have been commenced. The remote-area environmental health workers' program is being expanded. Increased intersectoral collaboration and enhanced community involvement in decision making have occurred as a result of this work.

Height of conscripts in Europe: is postneonatal mortality a predictor?

The height of conscripts has increased steadily during recent decades in Europe. We have collected data on conscript height from 11 European countries to examine if this trend is continuing. In the Scandinavian countries and The Netherlands the increase in height reached a plateau during the 1980s, while the trend towards increasing adult height continued in the middle and southern European countries. There are still large differences between the countries (1990: The Netherlands 181.2 cm and Portugal 170.3 cm), with a marked trend for the tallest conscripts to be in the north and the shortest in the shortest in the south. It has been suggested that the secular increase in adult height is mainly determined by an increase in growth during the first years of life. We examined postneonatal mortality (PNM) as a proxy for adverse environmental factors, mainly poor nutrition and infections, affecting growth during infancy, and related it to conscript height in the European countries. The general pattern was a rapid decrease in PNM until a low level was reached, after which it remained low, or decreased only very slowly. In countries where the increase in conscript height has levelled off, PNM reached a low and stable level (about 3-5 per thousand) approximately two decades before this stagnation. We speculate that the increase in height will continue in the rest of the European countries until approximately two decades after PNM has reached the same low level.

Epidemiology and microbiology of diarrhoea in young Aboriginal children in the Kimberley region of Western Australia

Infectious diarrhoea is common in young Australian Aborigines and is one of the main causes for their unsatisfactory health standards with consequent widespread failure to thrive and undernutrition. Most published reports relate to patients in hospital or to hospital admission statistics and give little indication of the extent or severity of diarrhoeal disease in children in Aboriginal communities. The present investigation involved more than 100 Aboriginal children up to 5 years of age living in remote communities in the tropical north of Western Australia who were studied prospectively over a 12-month period.

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.
