According to the new study, SIDS incidence relates to parents' psych hospitalizations, drug and alcohol abuse. Here are the odds:
*2x more SIDS if EITHER parent had been admitted to a hospital for a psychiatric illness OTHER than drug or alcohol disorders
*7x more SIDS if BOTH parents had a history of any mental illness requiring hospital admission
*almost 7x more if the mother had an alcohol or drug disorder
*9x more if both parents had an alcohol or drug disorder
Formerly known modifiable risk factors for SIDS:
maternal smoking
sleep position (on belly is risky)
