SLEEP CHARACTERISTICS IN HEALTHY-CHILDREN FROM BIRTH TO 6 YEARS OF AGE IN THE URBAN AREA OF ROME

The current survey is an attempt to evaluate age-specific sleep charac teristics and to identify the presence of sleep problems in Italian no rmally developing preschool-aged children. A cross-sectional survey by parental interview on sleep behavior was carried out on 2,889 childre n (from birth to 6 years). Groups were formed based on age level. Resu lts showed a developmental trend of some sleep characteristics, regard ing mainly the length of sleep and rating of night wakings. Comparison with other studies showed that the children in this study had a later sleep onset time and slept less than children of the same age Living in some other countries. These dissimilarities may be due to sociocult ural and climate differences. Sleep problems (sleep latency longer tha n 30 minutes or disruptive night wakings) were found in 35% of childre n less than 2 years old, in 23% of 2-3-year-olds and in 14% of 4-6-yea r-olds. Children with sleep problems slept significantly less (on aver age 30-40 minutes across all age levels, required parental presence at time of sleep onset and shared their parents' bed more frequently tha n those without sleep problems.
