Effect of Sleep Environment on Sudden Infant Death Syndrome (SIDS)

Sudden infant death syndrome (SIDS) is characterized by death of an infant that is not explained by medical history and remains unexplained even after an autopsy.

Infants during sleep have the highest risk of Sudden infant death syndrome (SIDS) and therefore it is referred as crib death or cot death.

The exact cause of sudden infant death syndrome is still unknown. The preventive measures for SIDS involve sleeping in well-ventilated rooms and putting infants on their back to sleep.

Avoid All Risk Factors for Sudden Infant Death Syndrome : Study
Sleeping on their back is not the only risk factor to avoid in SIDS, rather all other risk factors should also be considered.

Patricia Schnitzer and her colleagues evaluated 3136 sleep related infant death cases and identified the risk factors for sleep-associated sudden unexpected infant deaths (SUIDs) from the data collected from nine states that included Delaware, Hawaii, California, Michigan, Ohio, Nevada, Tennessee, Pennsylvania and Texas.

Recognition of the effect of hazardous environment on infant sleep is imperative to minimize the death of infants.

Only 25 percent of the infants were found to sleep on their back or in a crib while64 percent of the infants shared the sleeping space and nearly half of these infants shared the sleeping surface with adults.

The 3136 sudden unexpected infant deaths (SUIDs) were categorized into three segments- SIDS (30.6 percent), undetermined cause (39.5 percent) and suffocation (29.9 percent).

It was seen that most of the deaths occurred in male infants (57 percent) and in infants below the age of 4 months (71 percent). The majority of caregivers were female. Only 24 percent of infants were sleeping in a crib or bassinette at the time of death; 47 percent were in an adult bed, and another 13 percent were on a couch or chair. Twenty five percent of them were on their backs and 35 percent on their stomach.

Infant Sleep Campaigns to Prevent SIDS | Medindia:
Study reinforces the need for public education programs that encourage parents to place their babies to sleep in back position in a safe crib to prevent Sudden Death Syndrome (SIDS).

Seventeen percent of infants were noted to have a partially or fully obstructed airway. Sixty-four percent of all SUID victims were sleeping on the same surface as another person or animal when they died. More than 50 percent of the deaths were referred to a medical examiner, and an autopsy was performed on 94 percent of the infants presented the frequency distribution and proportion of deaths according to cause of death category, caregiver, and other selected characteristics.

Schnitzer said, “Since the Back-to-Sleep Campaign began, deaths from Sudden Infant Death Syndrome (SIDS) have decreased, but infant sleep-related deaths resulting from suffocation dramatically have increased.Sharing beds with infants is more common now, so we want to help new parents understand the risks."

Baby Products Do Not Prevent Sudden Infant Death Syndrome (SIDS) | Medindia:
Over the counter baby products cannot prevent Sudden Infant Death Syndrome says FDA. When a child under age one dies suddenly without an explainable cause of death.

Furthermore people believe that sharing bed with infants make breast feeding easier but contrary to this popular belief the practice is harmful to infants who should be hygienically placed in their separate environment after breastfeeding.

Despite the recommendations made by the experts, there has been continuous increase in sharing bed with infants. Future researches should emphasize and focus on developing novel interventions to facilitate behavioral changes and provide a safe infant sleep environment.
