Seasonal differences in suicide birth rates among Alaska Natives & for populations at different latitudes (resident of the Yukon, Saskatchewan, Montana, Wyoming, & Pennsylvania) were investigated. Seasonal birth rates for the general population were similarly examined. Suicide birth rates showed small seasonal variations for Alaska Natives with summer births showing more suicides. However, at lower latitudes, suicide birth rates among other populations showed no seasonal differences. Hours of daily sunlight at the summer & winter solstice correlated with the propotion of suicide victims born during those seasons. (18 refs.) JA
