Symptom Experience in Late Pregnancy.

OBJECTIVE: To evaluate the frequency, severity, distress, and correlates of common and rare symptoms reported by nulliparous women during the last month of pregnancy. DESIGN: Secondary cross-sectional analysis of data obtained in a larger randomized clinical trial. SETTING: San Francisco Bay area. PARTICIPANTS: Nulliparous, ethnically diverse, predominantly low-income pregnant women 18 to 47 years of age (N = 151). METHODS: Participants at or beyond 36 weeks gestation used the Memorial Symptom Assessment Scale (MSAS) to provide self-reports of general symptom experience. Other symptom measures were also completed for comparison. Demographic characteristics, including gestational weight gain, were also collected. Gestational weight gain was categorized in relation to the Institute of Medicine's 2009 recommendations for weight gain during pregnancy. RESULTS: Women endorsed an average of 10.6 ± 5.6 symptoms on the MSAS. Prevalent symptoms (reported by at least half the sample) included lack of energy, pain, difficulty sleeping, worrying, irritability, drowsiness, shortness of breath, and nervousness. Among the women who reported these symptoms, relatively few described them as occurring with high frequency or severity or as causing much distress. One of the most prevalent symptoms (reported by 68% of women) was difficulty sleeping, which also had among the greatest ratings for frequency, severity, and distress. Although few maternal characteristics were associated with symptom experience, women who gained more weight than the Institute of Medicine's recommendation had worse MSAS total scores than women who gained the recommended amount or less. CONCLUSION: In nulliparas, symptom frequency, severity, and distress varied and were related to excessive gestational weight gain.

Sleep disruption and duration in late pregnancy is associated with excess gestational weight gain among overweight and obese women.

BACKGROUND: Poor sleep during pregnancy has been associated with poorer birth outcomes. High body mass index (BMI) is often associated with poor sleep, but little is known about the relationship between gestational weight gain and sleep in late pregnancy. The purpose of this study was to evaluate the relationships of both gestational weight gain and pre-pregnancy BMI to objective and subjective measures of sleep during late pregnancy. METHODS: Pregnant women (n=128) were recruited from prenatal clinics and childbirth classes primarily serving low-income women. Their sleep (disruption and duration) was objectively assessed in their last month of pregnancy with 72 hours of wrist actigraphy monitoring. Their perceived sleep quality was assessed with the Pittsburgh Sleep Quality Index. Pre-pregnancy and late pregnancy height and weight were assessed by self-report and used to calculate BMI and gestational weight gain, which were then grouped into standardized categories. RESULTS: Mean Pittsburgh Sleep Quality Index score was 6.8 ± 3.1 (range 2-16). Sixty percent had excess gestational weight gain and it was associated with poorer perceived sleep quality, but was unrelated to objective measures of sleep duration and disruption. Pre-pregnancy BMI was unrelated to all sleep parameters. However, analyses of the interaction of pre-pregnancy BMI and gestational weight gain indicated that excess weight gain was associated with shorter sleep duration and more sleep disruption, but only among women who were overweight before pregnancy. CONCLUSION: Pregnancy is an opportunity to promote long-term women's health with a better understanding of the relationship between weight management and healthy sleep habits.
