Kawasaki syndrome in Washington State: race-specific incidence rates and residential proximity to water

Article Abstract:

A new system for collecting data in Washington state has enabled the determination of the race-specific incidence rate of Kawasaki syndrome (KS) as well as its association with proximity to bodies of fresh water. The cause of KS is unknown, but studies have suggested that proximity to a body of water is associated with increased incidence. The annual incidence rate of KS in children under age 5, the most susceptible age group, in 3 Washington counties was 15.2 per 100,000 from 1987 to 1989. The rate of KS was highest in Asian Americans and lowest in whites. This suggests a genetic susceptibility among Asians. Rates were substantially lower than rates in Japan, but the Asian American children represent many nationalities. Children contracting KS were no more likely to live within 150 yards of water than a group of matched children. However, this did not preclude temporary bodies of water caused by rainfall.

Lipoprotein and apolipoprotein differences in black and white girls: the National Heart, Lung, and Blood Institute Growth and Health Study

Article Abstract:

There may be racial differences in blood levels of cholesterol and triglycerides in prepubertal girls. Researchers measured blood levels of cholesterol and triglycerides, height-to-weight ratios, and skinfold thickness, a measure of body fat, in 1,871 black and white, 9- to 10-year-old girls. Black girls tended to be heavier for height than white girls while body fat content was similar. White girls averaged higher triglyceride values than black girls. Black girls averaged higher high-density lipoprotein cholesterol and apolipoprotein A-1 levels, a cholesterol component, than white girls. Low-density lipoprotein cholesterol levels were similar.

Risk factors for the infant prone sleep position

Article Abstract:

Unmarried and teenage mothers may be more likely either to be unaware of or to disregard advice to place their infants in the nonprone position for sleep. Researchers interviewed parents of 178 infants regarding the sleep position they used for their infants. Twenty-eight percent of the parents said their infants slept in the prone position, 67% slept nonprone, and 5% varied. Teenage mothers were more likely to place their infants in the prone position even if they had heard advice to the contrary. They may need special education.
