"We found that when a mother reported her child as having sleep problems -- at ages 3 to 5 - that child was twice as likely to have drug and alcohol abuse problems," researcher Maria Wong, MD, a professor of psychiatry at the University of Michigan, Ann Arbor, tells WebMD. Her study appears in the current issue of Alcoholism: Clinical and Experimental Research.

Bad parenting may be driving the child's sleep problems, points out Louis B. Antoine, MD, a child and adolescent psychiatrist at the University of Miami School of Medicine. He agreed to comment on Wong's findings.
"After all, what is the definition of sleep problems in a toddler?" asks Antoine. "Let's say a mother has sleep problems of her own. Let's say she's not very sophisticated about children, doesn't understand child development very well, has problems herself that make her impatient. Also, is the child being fed properly? Is there an anxiety disorder, nightmares, fear of the dark? Is the child hyperactive, so wired that he's not able to settle down?"
Boys Sleeping Badly
For their study, Wong and her colleagues recruited 257 boys from families, many of which (60%) were considered high risk for drug and alcohol abuse, because the father was an alcoholic. Mothers rated their sons' early childhood (aged 3 to 5) sleep problems, problems such as overtiredness and having trouble sleeping. Attention problems anxiety or depression symptoms, and signs of aggressive behavior were also reported by mothers.
The boys themselves reported on their drinking, smoking, and drug use habits from age 12 to 14.
Wong found that those with early childhood sleep problems were:
- Twice as likely to start using alcohol by 12 to 14.
- Twice as likely to be regular smokers.
- Twice as likely to use illicit drugs.
- Three times more likely to use marijuana.
The findings held true -- even after anxiety, depression, aggression, and attention problems were taken into account. It was also true, whether parents were alcoholics or not.
