Non-reassuring foetal status and sleep problems in 1-year-old infants in the Japan Environment and Children’s Study: a cohort study

Abnormal autonomic function may cause false-positive non-reassuring foetal status ( fp NRFS) and may also cause sleeping problems after birth. However, an association between fp NRFS and sleeping problems in infants has not been reported. We previously showed an association of NRFS with temperament,...

Description
Summary:Abnormal autonomic function may cause false-positive non-reassuring foetal status ( fp NRFS) and may also cause sleeping problems after birth. However, an association between fp NRFS and sleeping problems in infants has not been reported. We previously showed an association of NRFS with temperament, including bad mood and frequent crying for long durations in 1-month-old infants. In the present study, we aimed to assess this association in 1-year-old infants. A total of 62,612 single pregnant women were included in the analysis. fp NRFS was identified from medical records. Sleep problems, such as short sleep duration or crying at night, were investigated in 1-year-old infants using a questionnaire for mothers. We used a log-binominal regression model to explore the association of fp NRFS with each sleep problem and to estimate risk ratios (RRs). The number of fp NRFS cases was 2,071, with a frequency of 3.3%. We observed an association of fp NRFS with shorter sleep duration of less than 8 h a night (RR 1.30, 95% confidence intervals [CI] 1.10–1.54), crying at night (RR 1.19, 95% CI 1.03–1.39), and bedtime after 22:00 (RR 1.09, 95% CI 1.00–1.18). fp NRFS may be associated with sleep problems in 1-year-old infants.
