Sleep Problems and Their Correlates in Children with Autism Spectrum Disorder: An Indian Study.

Doctors in India asked the kids with autism and 80 typical kids about sleep. All children were 3 to 12 years old. Parents filled out the Children’s Sleep Habits Questionnaire and other checklists on behavior, senses, and motor skills.

Kids with autism had far more sleep problems, especially trouble falling or staying asleep. The worse the sleep-wake issues, the higher the child’s autism severity, hyperactivity, sensory problems, and clumsy movements.

Greene et al. (2019) extends these findings to adults. They show that autistic adults who still meet criteria for insomnia are far more likely to be unemployed. Together, the two papers trace a line: childhood sleep-wake problems can echo into adult job loss.

Adams et al. (2020) and Adams et al. (2025) add anxiety to the picture. They find almost every autistic child reports anxiety, and that anxiety—not sleep—best predicts later school refusal. Vernika et al. link anxiety to sleep, while Dawn et al. link anxiety to attendance. The results do not clash; they simply spotlight different stops on the same worry chain.

Chen et al. (2020) tighten the knot: anxiety and depression mediate suicidality risk in kids with high autistic traits. Sleep, attendance, mood, and safety all thread through anxiety.

When an autistic child shows bedtime resistance, look wider. Rate hyperactivity, sensory seeking, and motor delays the same day. Treating sleep may calm these downstream issues and, as K et al. hint, could even protect future employment. Also, track anxiety at every visit; it is the common driver of sleep loss, school refusal, and mood risk. One quick screener now can guide tonight’s bedtime plan and tomorrow’s classroom support.
