| Outline of Final Research Achievements |
The objective of this study was to explore the possibility of using distal-proximal skin temperature gradient (DPG) to predict sleep-onset latency of night-time sleep for infants . Foot (for distal) and abdominal (for proximal) skin temperature during sleep onset in healthy infants, aged 4-9 months, was continuously recorded using a temperature logger . Sleep-onset latency during each study night was defined as the interval from lights-off to sleep onset, determined on actigraphy. Association of DPG profile after lights-off with sleep-onset latency on the study nights was evaluated. Data were available for analysis.With regard to low DPG (<－2.5°C) at lights-off, >60% of infants fell asleep within 30 min if DPG was increased to ≧－2.5°C within 15 min after lights-off. If infants were still awake at 15 min after lights-off and the DPG at that time was <－2.5°C, they were not likely to quickly fall asleep (predictive value was 0.875).
