The Tokelau Islands children's study: atoll and New Zealand comparisons: physical growth.
A comparison is made between the birth weights, weights, heights, skinfold thicknesses, and head circumferences of two groups of Tokelauan children aged under 15 years. One group was living in Tokelau on their three home atolls and the other group was living in New Zealand. The children living in New Zealand were in general heavier, taller, had more body fat and larger head circumferences than the children living in Tokelau.
Post-neonatal infant deaths in the Auckland Hospital Board area 1972.
A study has been made of the final, and contributory, causes of post-neonatal deaths in the Auckland Hospital Board area for 1972. There was a high rate of deaths from infection. Maori infants died from pneumonia at a rate 28 times that of european infants. Prevention of these infant deaths will need improvement in parent recognition of illness, medical practitioner availability and training, and hospital facilities.
Sudden infant death syndrome: hypothesis of causation.
The airway of the young infant is anatomically vulnerable at the oropharyngeal level between the soft palate and the base of the skull. Airway occlusion at this level might occur during the muscle relaxation which occurs during REM sleep, facilitated by a hypermobile mandible, by the hypotonia of infection, perhaps by an enlarged tongue with a strong backwards sucking action which might be the result of the artificial feeding of the infant. It is possible that "cot deaths" (SIDS) may be precipitated by such oropharyngeal airway occlusion, cardiac arrest following variable periods of partial or complete oxygen deprivation.
