| Abstract: | Objectives We compared the sleep of infants at risk forneuromotor delays to that of infants without such risks, andexamined the predictive validity of risk indicators to the developmentof sleep problems. Methods Conveniently recruitedinfants (n = 142) were assessed for neuromotor achievementsand sleep behaviors at 4–6 months and 10–12 monthsof age. Assessment tools were the Harris Infant Neuromotor Testand Morrell's Infant Sleep Questionnaire. Based on a cumulativerisk index, three groups were defined: higher risk (n = 28),lower risk (n = 42), and no risk (n = 72). Results Atboth ages, the sleep scores were similar among the groups. Inthe no risk and lower risk group, sleep difficulties decreasedwith age, while for infants in the higher risk group, more difficultieswere reported over time. Overall, the neuromotor attainmentswere not related to sleep fragmentation or settling difficulties. Conclusions Ina diverse sample of infants, with and without risks for developmentaldelays, overall, sleep patterns were similar. It appears thatthe neuromotor achievements are not associated with sleep-wakeregulation, as measured by caregivers report. |
