   Childhood Sleepwalking and Sleep Terrors: A Longitudinal Study of Prevalence and Familial Aggregation

   Статистика

   Prospective Quebec Longitudinal Study of Child Development cohort, N=1,940 children followed 1999-2011: sleepwalking prevalence peaked at 13.4% (95% CI 11.3%-15.5%) at age 10; childhood sleepwalking prevalence was 22.5% with no parental history, 47.4% with one sleepwalking parent, and 61.5% with two

   Витяг

   “"The peak of prevalence was observed at 1½ years for sleep terrors (34.4% of children; 95% CI, 32.3%-36.5%) and at age 10 years for sleepwalking (13.4%; 95% CI, 11.3%-15.5%)." ... "The prevalence of childhood sleepwalking increases with the degree of parental history of sleepwalking: 22.5% (95% CI, 19.2%-25.8%) for children without a parental history of sleepwalking, 47.4% (95% CI, 38.9%-55.9%) for children who had 1 parent with a history of sleepwalking, and 61.5% (95% CI, 42.8%-80.2%) for children whose mother and father had a history of sleepwalking."

   Used only as context for exposure: how many children sleepwalk at all. The 13.4% peak at age 10 is a point prevalence in that year; the 22.5% / 47.4% / 61.5% figures are cumulative childhood prevalence stratified by parental history. No injury outcome is reported, so nothing is converted to a native or normalized probability. The parental-history gradient is described in prose rather than as personal_factor_multipliers because this entry carries no_reliable_estimate and the gradient shifts the chance of sleepwalking, not the chance of injury given sleepwalking.

   The journal's own press release for Petit et al. (2015), cited because it states the cumulative 2½-to-13 figure in one line. The 29.1% could not be found in the indexed abstract text via search, so it rests on this release rather than the peer-reviewed abstract; the abstract's parental-history strata (22.5% to 61.5%) are consistent with it. Rounded to "about 29%" / "about 3 in 10" in the quick answer and prose. Exposure context only; no injury figure.

   Незалежність

   Not independent of Petit et al. (2015); it summarizes the same study.

   Prevalence of Sleepwalking: A Systematic Review and Meta-Analysis

   Статистика

   Meta-analysis of 51 studies (N=100,490): lifetime sleepwalking prevalence 6.9% (95% CI 4.6%-10.3%); 12-month prevalence 5.0% (95% CI 3.8%-6.5%) in children versus 1.5% (95% CI 1.0%-2.3%) in adults

   Витяг

   “"The estimated lifetime prevalence of sleepwalking was 6.9% (95% CI 4.6%-10.3%). The current prevalence rate of sleepwalking within the last 12 months was significantly higher in children [5.0% (95% CI 3.8%-6.5%)] than adults [1.5% (95% CI 1.0%-2.3%)]."

   Supplies the pooled 12-month figure: roughly 1 in 20 children sleepwalk in a given year. The pooled lifetime figure (6.9%, mixed ages) is far below the Quebec cohort's 29.1% because most pooled studies used single retrospective questions rather than repeated prospective parent reports (an interpretation, not a finding of either paper), which suggests sleepwalking counts are sensitive to method. Exposure context only; no injury figure.

   Незалежність

   Somnambulism: Emergency Department Admissions Due to Sleepwalking-Related Trauma

   Статистика

   11 sleepwalking-related trauma presentations among about 620,000 ED admissions at Inselspital, Bern, 2000-2015; falls were the leading mechanism; 4 of 11 (36.4%) were hospitalized; no deaths; adult department treating patients aged 16 and over (two of the 11 were 16)

   Витяг

   “"Of 620,000 screened ED admissions, 11 were associated with trauma and sleepwalking." ... "Although sleepwalking seems benign in the majority of cases and most of the few injured patients will not require hospitalization, major injuries are possible." [First sentence from the abstract; second from the full-text Conclusion (the abstract reads "did not require"). Both checked against the Europe PMC full text, 2026-09-27] ”

   The only systematic count of sleepwalking injuries located. It cannot anchor a pediatric estimate: the adult department treats patients aged 16 and over, there is no denominator of sleepwalkers in the catchment, and cases were found by chart search, which misses injuries not recorded as sleepwalking-related. 11 / 620,000 is a share of ED visits (about 1 in 56,000), not a probability per sleepwalker, and is shown for scale only. This is the reason for no_reliable_estimate.

   Pediatric safety guidance for sleepwalking children: gates at bedroom door and/or stair top; locked windows and doors

   Establishes that stairs and windows are the hazards pediatric guidance singles out. Guidance, not evidence of frequency: it gives no injury rate and no data on how much gates or locks reduce injury among sleepwalkers. source_date set to access date because the page shows a rolling review date.
