Lactose malabsorption in Australian Aboriginal children. 1985

J C Brand, and I Darnton-Hill, and M S Gracey, and R M Spargo

The purpose of this study was to determine the prevalence of lactose malabsorption in healthy full-blood Australian Aboriginal children. Sixty-three Aboriginal subjects and forty-six non-Aboriginal controls ranging in age from six to 14 years were tested using the breath hydrogen method. Seventy percent of the Aboriginal subjects were found to be lactose malabsorbers and 9% of the controls. The results provide strong evidence that the majority of full-blood Aboriginal children are lactose malabsorbers and that the characteristic is well-established by 6-7 years of age, in common with most other non-Western populations.

UI	MeSH Term	Description	Entries
D007787	Lactose Intolerance	The condition resulting from the absence or deficiency of LACTASE in the MUCOSA cells of the GASTROINTESTINAL TRACT, and the inability to break down LACTOSE in milk for ABSORPTION. Bacterial fermentation of the unabsorbed lactose leads to symptoms that range from a mild indigestion (DYSPEPSIA) to severe DIARRHEA. Lactose intolerance may be an inborn error or acquired.
