Abstract

Objective. Data on human natality, stillbirth and perinatal mortal; from Switzerland (1979-1987), available in four birthweight categories, are reexamined to assess any about-weekly (circaseptan) and changes in about-daily (circadian) patterns in central Europe over a century and a half. Design. Retrospective analyses on arehived data. Setting. Federal Office of Statistics for Switzerland. Results. In addition to prominent circadians, weekly patterns are also documented. Conclusion. Exogenous variations, prominent in early extrauterine life, such as changes of scheduling in obstetrics, may contribute to circadian and circaseptan natality patterns. Information on these patterns serves in the optimization of neonatal care. Partly endogenous, partly physical environmental aspects, at least of about-weekly patterns, remain to be elucidated in series consisting exclusively of spontaneous parturitions.
