Abstract

A randomized controlled study was carried out on 96 preterm infants (>37 wk) with birthweight less than 2000 g admitted to a neonatal intensive care unit. The aim was to compare the weight gain between preterm infants exposed to 12 h cyclical lighting (intensity of light: 78.4 ± 24.7 lux, mean ± SD) and those exposed to a continuously dim environment (5.9 ± 1.9 lux). The exclusion criteria were infants with major congenital malformations or who needed continuous lighting for treatment procedure and care. From day 7 of life until discharge, 50 infants were randomized to receive 12 h cyclical lighting and 46 infants to a continuously dim environment. There was no significant difference in the mean birthweight (12 h lighting vs continuously dim: 1482 vs 1465 g, p= 0.8), mean gestational age (31.6 vs 31.4 wk, p= 0.6), median duration of hospital stay (28.5 vs 28.5 d, p= 0.8), mean age to regain birthweight (13.0 vs 12.9 d, p= 0.3), mean weight gained by day 14 (27.6 vs 36.2 g, p= 1.0), median weight gain per day (11.9 vs 12.2 g, p= 0.9) or median body weight on discharge (1800 vs 1800g, p= 0.4) between the two groups of infants. Conclusion: Exposing preterm infants to either 12 h cyclical lighting or continuously dim environment did not have any significant effect on their weight gain during the neonatal period.

  • 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.
