Abstract

Objectives Our purpose was to evaluate the benefits of cycled light (CL) versus near darkness (ND) on health in preterm infants born at <31 weeks' gestational age.Study design Randomized, interventional study comparing infants receiving (1) CL from birth, (2) CL at 32 weeks' postconceptional age (PCA), and (3) CL at 36 weeks' PCA in transition for discharge home. Statistical significance was assessed with segmented mixed general linear models, analysis of covariance, general estimating equations, chi(2), and Fisher's exact procedure.Results Infants receiving CL at birth and 32 weeks' PCA gained weight faster than infants not receiving CL until 36 weeks' PCA. There were no differences among the groups in length of hospitalization stay or number of ventilator days, but the power was low for these variables.Conclusions These findings suggest that CL has significant weight gain benefits over ND, and there are no short-term advantages of ND over cycled light for health in preterm infants.

  • Premature infants kept in regular light-dark conditions also fed orally sooner and spent fewer days on ventilator assistance, but had similar motor coordination compared with infants under continuous near darkness in the NICU (28-32 weeks of gestation).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
