Survey examines prevalence of short sleep duration among US adults

This observational survey report analyzed data from the National Health Interview Survey to assess sleep duration patterns among US adults aged 18 years and older. The study specifically examined the percentage of adults who sleep less than seven hours on average in a 24-hour period. No intervention or comparator was reported in this descriptive analysis.

The main outcome was the percentage of adults with short sleep duration (less than seven hours). However, the actual prevalence result, effect sizes, absolute numbers, p-values, and confidence intervals were all not reported in the available data. The direction of any trends or comparisons was also not specified.

No safety, tolerability, or adverse event data were reported for this survey-based analysis. Key limitations include the observational nature of the data, which prevents causal inference, and the absence of reported numerical results. The funding sources and potential conflicts of interest were not reported. This survey provides descriptive context about sleep patterns in the US adult population but offers limited clinical guidance due to missing outcome data.
