title: Seasonal distribution of live births in a rural community in the southern United States.
abstract: "Births in Greene County, Alabama for the years 1980-1984 were examined and an overall seasonal trend was found with a peak from August through November.  This trend was found to be most pronounced among women greater than 24 years old, and among multiparous women, and to be negatively correlated with seasonal variations in temperature and daylight.  The phenomenon is likely multifactorial in origin, with sociocultural factors playing a considerable role.  The influence of increasing maternal age and parity in the expression of the seasonal trend may be a function of age-related changes in families, with nuclear families acting as the most powerful potentiators of seasonality."
