We undertook a 1-year prospective point prevalence study to test the hypothesis that there is an excess of non-diabetic renal disease in native American children; 29.6% (73/247) of the population attending the only regional pediatric nephrology clinic in 1993 were native compared with 8.2% of the Manitoba population in this age group (odds ratio = 4.4, P
Injuries and deaths associated with off-road recreational vehicles are of increasing concern in North America. We reviewed all hospital admissions and deaths attributed to these vehicles in Manitoba from April 1979 to April 1985 among children 16 years of age or younger. Of the 693 hospital admissions and deaths 480 were associated with motorbikes, snowmobiles or all-terrain vehicles (ATVs). The incidence of injuries resulting from snowmobile and dirtbike accidents remained stable over the study period; however, there was an almost exponential increase in the number of admissions because of ATV-related injuries. There were 21 deaths during the study period. Preventive measures through legislation are necessary to reduce the numbers of injuries and deaths; these include mandatory registration, licensing and enhanced safety regulations.

Using a cross-sectional survey, to investigate the vitamin D status of a random sample of 80 mother-child pairs (child age 3-24 months) in a Manitoba community with a high incidence of rickets.
A questionnaire on feeding habits, gestational history, maternal diet and vitamin supplements was administered to mothers in their homes with the assistance of a local interpreter. Venous blood was collected from both mother and child for serum 25-hydroxyvitamin D levels.
Of 91% babies initially breastfed, 36% received no formula or milk after weaning and 40% received no vitamin supplements. 24% of mothers took no vitamin supplements during pregnancy and lactation. Knowledge about rickets was poor. In 43% of children and 76% of mothers, serum 25-hydroxyvitamin D levels were below normal range.
Vitamin D levels are low in this population due to lack of fortified dairy products and vitamin D supplements. A public health program should include counseling on rickets and vitamin D supplementation for all infants and pregnant or lactating women.
