Sleep Patterns Affect Obesity in Young Children

This new study is intriguing, but more analysis is needed. First, we would suspect that sleep-disordered breathing is present in some of these kids, which could produce fragmented sleep, awakenings, and ultimately short sleep duration, a fairly common presentation for SDB in children. Second, the connection to TV viewing also suggests something about family dynamics. If parents let their kids watch too much television, it may say a lot about the parents’ own energy levels and the need to use “surrogates” to entertain the kids, while the parents try to recover their own energy or manage other tasks. In short, the more the parents let their kids watch TV, then the more the parents may suffer from their own sleep problems, which they pass on genetically to the kids. And these sleep disorders may be an obesity trigger or contributor.

In sum, I doubt it’s as simplistic as just the number of hours these children sleep. Rather, the number of hours they sleep is a marker of another process that also influences weight.
