The Impact of Physical Activity on Sleep during Pregnancy: A Secondary Analysis

摘要: Disturbed sleep is independently associated with adverse pregnancy outcomes. The primary aim of this research which tested Pender’s Model Health Promotion was to evaluate the contribution physical activity (PA) parameters in pregnant women, pre-pregnant body mass index (BMI) as a confounder. Sleep and data were drawn from parent study 29 sedentary women second trimester enrolled an 8-week PA intervention pilot randomly assigned or control group. Steps per day, measured by pedometer, (sleep onset latency [SOL], wake time after [WASO], duration, quality), obtained diaries, used daily interaction between levels sleep. Hierarchical linear modelling (HLM) for analysis, nested within persons. Pre-pregnant BMI contributed negatively (p=0.003). positively predictive (p=0.037) (SOL) (p=0.01) quality, demonstrating negative effect on during when daily. These results confirm only other published that looked at measures, but contradict findings studies evaluated level-sleep relationship over week month. Both are modifiable factors affect Further needed understand complex PA, sleep, weight pregnancy.
