Trends in Self-Reported Sleep Duration among US Adults from 1985 to 2012.

ABSTRACT:

Study objective

The trend in sleep duration in the United States population remains uncertain. Our objective was to examine changes in sleep duration from 1985 to 2012 among US adults.

Design

Trend analysis.

Setting

Civilian noninstitutional population of the United States.

Participants

324,242 US adults aged ≥ 18 y of the National Health Interview Survey (1985, 1990, and 2004-2012).

Measurements and results

Sleep duration was defined on the basis of the question "On average, how many hours of sleep do you get in a 24-h period?" The age-adjusted mean sleep duration was 7.40 h (standard error [SE] 0.01) in 1985, 7.29 h (SE 0.01) in 1990, 7.18 h (SE 0.01) in 2004, and 7.18 h (SE 0.01) in 2012 (P 2012 versus 1985 < 0.001; P trend 2004-2012 = 0.982).
