Abstract
OBJECTIVE: To assess whether the recommendations that infants sleep supine could have adverse health consequences. DESIGN: A prospective study of infants, delivered before, during, and after the Back to Sleep Campaign in the United Kingdom (UK), followed to 6 months of age. The children were part of the Avon Longitudinal Study of Pregnancy and Childhood (ALSPAC). Subjects. Singletons born to mothers resident in the three former Bristol-based health districts of Avon in the period June 1991 to December 1992, and for whom questionnaires were completed on sleeping position at 4 to 6 weeks of age (n = 9777); for these infants 8524 questionnaires were also completed at 6 to 8 months of age. MAIN OUTCOME MEASURES: Subjective measures of health, the presence of specific signs and symptoms, duration of sleep at night, and calling the family doctor to the home. RESULTS: Of 43 outcomes considered, after adjustment for 12 factors using logistic regression only 2 were associated with raised risk among infants put to sleep on their back (diaper rash and cradle cap). Infants put to sleep prone had increased risk of a number of health outcomes, including cough and possibly pyrexia. CONCLUSIONS: There is no evidence that putting infants to sleep in the supine position results in increased morbidity, although changes in prevalence of rare disorders would not have been identified.
