Risk Factors for Shorter Infant Sleep Duration

Early introduction of solid food, television viewing, and maternal prenatal depression were associated with shorter sleep duration.

To determine early-life risk factors associated with shorter sleep duration during infancy, investigators followed 1676 pregnant women at eight obstetrical offices in Massachusetts until their children's second birthdays. Mothers reported average 24-hour sleep duration during the past month for their infants at ages 6 months, 1 year, and 2 years.

In multivariable regression models adjusted for sociodemographic factors, maternal prenatal depression (measured on a validated screening tool), introduction of solid foods at age <4 months, and infant television viewing were significant risk factors for shorter sleep duration at age 1 year (0.36 fewer hours/day for maternal prenatal depression, 0.39 fewer hours/day for early introduction of solid f…
