Truth,
“In 1992, to address the unacceptable SIDS rate, the American Academy of Pediatrics initiated a ‘Back to Sleep’ campaign, convincing parents to place their infants supine, rather than prone, during sleep.
From 1992 to 2001, the postneonatal SIDS rate dropped by an average annual rate of 8.6%. However, other causes of sudden unexpected infant death (SUID) increased.
For example, the postneonatal mortality rate from ‘suffocation in bed’ (ICD-9 code E913.0) increased during this same period at an average annual rate of 11.2%.”
Not sure if you understand the terms, postneonatal mortality includes SIDS, its basically any mortality that occurs between 28 days and 1 year of age.
This includes anything, yet the trend of unexplained deaths in infants have dropped significantly, while the mortality rate in other groups has also dropped yet not as significant.
There is evidence based on studies that sleeping in the prone position, the mother having an unhealthy lifestyle and better neonatal care have an effect on SIDS.
