“…Obesity has been recognized as a risk factors for poor sleep quality antenatally [ 33 ]. In a large-scale prospective study ( n = 2366), Guinhouya et al showed that pre-pregnancy high BMI correlates with poorer overall PSQI score [ 22 ]. Another study by Vézina-Im et al showed no difference in sleep duration among women in different BMI groups [ 34 ].…”

Background Pregnancy associated sleep disturbances is a common pregnancy-related complication which can lead to significant maternal distress and adverse pregnancy outcomes. Sleep quality can be affected by multiple factors and obesity has been recognized as one of them. Various previous studies have demonstrated poorer sleep quality during pregnancy. However, most studies included assessment at only one point of pregnancy. This prospective cohort study aimed to better evaluate the effect of pregnancy on the quality of sleep throughout the antenatal period and how BMI affects antenatal sleep. Methods A total of 926 women were recruited before 14 weeks of gestation and followed throughout pregnancy. The Pittsburgh Sleep Quality Index questionnaire (PSQI) was employed to assess sleep quality in 4 antenatal visits throughout pregnancy. Their weight was also recorded at each visit. Results The PSQI global score was higher towards the later part of pregnancy (6.4 to 8.0, p < 0.001) and highest at the 4th visit. Sleep latency was longer as pregnancy progressed (18.5 mins to 23.2 mins, p = 0.001). Sleep duration became shorter over time and was the shortest at the 4th visit (7.1 h to 6.5 h, p < 0.001). Sleep efficiency was the lowest at the 4th visit (85.2 to 81.6%, p < 0.001). The same trend was observed for subjects in different BMI groups throughput pregnancy. PSQI score increased and sleep duration decreased as BMI increased. The effect of increasing BMI on PSQI and sleep duration was only observed in the higher BMI groups (> 25 kg/m2). Conclusions Our study showed that sleep quality gradually declined throughout pregnancy for all BMI groups. Higher BMI was associated with poorer sleep as represented by PSQI score and sleep duration, particularly in the overweight and obese subgroups.

“…Biological tracking with wearable monitors could provide biobehavioral information to research pregnancy, birth, or postpartum experience. Thus, questions such as sleep quality in pregnancy 25 or exercise could be examined in far greater detail and depth than with periodic or self‐reported measures 26 . The applications also permit direct data entry, allowing participants to self‐report data to augment smartphone‐collected measurements.…”

One of our team members is using a wearable ring to measure changes in peripheral physiology (eg, temperature, heart rate variability, movement, and sleep measures) prior to the onset of labor.…”

In 2020, in-person research activities were stopped because of the spread of the novel coronavirus, severe acute respiratory syndrome coronavirus 2, and the resulting disease, coronavirus disease 2019. Our collaborative team of nurse and midwife scientists at universities across the United States adapted research activities to continue prospective perinatal research during the pandemic. These adaptations included development of new research techniques and the implementation of previously developed, but underused, strategies to conduct research from a distance. These strategies included online recruitment, virtual enrollment and consent, qualitative data collection via video conferencing, new applications of smart phone technology, wearable biological measurement, and participant self-collection of biological samples. In addition to allowing research to continue during the pandemic, these innovative strategies may increase access to research for low-income, rural, and racially diverse pregnant and postpartum populations. Decreased travel requirements, flexible scheduling, wearable devices, and the capacity to self-collect biologic samples may improve recruitment and the experience of research participation. The rapid implementation of these research strategies has advanced innovation toward wider, more inclusive and increasingly diverse perinatal research access, and many of these strategies will continue to be used and refined.

“…Although evidence suggests that food intake patterns may be influenced by the physiological and behavioral demands of pregnancy and postpartum [ 33 , 34 , 35 , 36 , 37 ], few studies have examined the relationship of food intake patterns with diet quality or energy intake during this developmental period. Among the few studies of food intake patterns in pregnant and postpartum women, relations of meal frequency with total energy intake have been inconsistent [ 38 , 39 , 40 ], and findings of an inverse association of late-night eating with energy intake [ 41 ] and a positive association of meal skipping with diet quality [ 42 ] are contrary to findings in the general population.…”

This study investigates the relationship between meal-specific eating patterns during pregnancy and postpartum with maternal diet quality and energy intake. Participants in a prospective cohort study completed 24-h dietary recalls three times throughout both pregnancy and 1 year postpartum (n = 420). Linear regressions estimated the associations of eating frequency (number of daily main meals and eating occasions), meal and energy regularity (meal skipping and variation of daily energy intake), and intake timing patterns (distribution of energy intake throughout the day, derived using principal component analysis) with daily energy intake and diet quality (Healthy Eating Index-2015, calculated daily and overall, across both pregnancy and postpartum). Eating frequency was positively associated with energy intake and daily diet quality. Irregular meals were associated with lower energy intake in pregnancy but not postpartum and with lower pregnancy and postpartum diet quality. Energy irregularity was not associated with energy intake or diet quality. Higher postpartum diet quality was associated with a morning energy intake pattern (versus late morning/early afternoon or evening). Differences in these associations between pregnancy and postpartum suggest that efforts to support optimal energy intake and diet quality by modifying eating patterns may require specific strategies for pregnancy and postpartum.
