Infant health outcomes among offspring of male U.S. military divers

Abstract

While there are suggestions that the extreme hyperbaric conditions encountered during deep saturation diving may impact male reproductive function, few studies have investigated whether paternal occupational diving influences offspring health outcomes. To examine this, Department of Defense Birth and Infant Health Research program data were used to identify the offspring of male active duty divers and non-divers in the U.S. military, 2001-2016. Log-binomial regression models estimated associations with infant outcomes (e.g., major structural birth defects, low birthweight). Among 1,148,252 identified singleton infants, 3,843 were considered the offspring of male divers; paternal occupational diving was not positively associated with any adverse infant outcome under study. These findings corroborate existing literature and further suggest that male divers in the U.S. military are not occupationally exposed to reproductive hazards that adversely influence offspring infant health outcomes.
