Early bedtime in preschoolers reduces risk of obesity in teens by half

For time untold, parents have been convincing their children to go to bed early, and now research proves that the results of an early bedtime are substantial later in life. Not only does a good night’s sleep have innumerable benefits in the present, but it greatly reduces the risk of obesity later in life.

According to a new study published in the Journal of Pediatrics, preschool-aged children with earlier bedtimes were one-half as likely to be obese later in life compared to children with later bedtimes.

“For parents, this reinforces the importance of establishing a bedtime routine,” said study author Sarah Anderson, an associate professor of epidemiology. “It’s something concrete that families can do to lower their child’s risk and it’s also likely to have positive benefits on behavior and on social, emotional and cognitive development.”

Researchers from the Ohio State University’s College of Public Health analysed data from 977 of 1364 participants in the Study of Early Child Care and Youth Development. Between 1995 and 1996, the typical bedtime of the preschool aged children were reported by mothers. And later at an average age of 15, the height and weight of participants were measured and obesity defined against a sex-specific body-mass-index-for-age (≥95th percentile of the US reference).

The study was divided into three groups depending on the child’s bedtime: 8 p.m. and earlier, between 8 and 9 p.m., and later than 9 p.m. Half of the kids fell in the middle group, while the other half was split between the first and last group.

Results showed that 10% of kids who had the earliest bedtime were obese as a teen. Around 16% of kids with the 8-9 p.m. bedtime and 23% of kids with the latest bedtimes were also found to be obese as adolescents.

Researchers looked into multiple variables related to the emotional state of the house that could also influence obesity later in life, but found regardless of maternal sensitivity, an earlier bedtime had the strongest link with reduced obesity later in life.
