OBJECTIVES: Higher energy intake has been associated with increased gestational weight gain (GWG). However, the effects that individual macronutrients have on GWG remain unclear. We examined the putative mediating effect of macronutrient composition on GWG after an intervention aimed to track prenatal energy needs. METHODS: In this controlled trial, pregnant women aged >18 yr old (X = 29.8 ± 4.9 yr) with a gestational age (GA)

OBJECTIVES: Resting energy expenditure (REE) comprises 60% of total energy expenditure and variations may be associated with gestational weight gain (GWG). There is a paucity of research investigating the relationship between REE and GWG. We investigated variations in REE and dietary composition throughout the second trimester and their association with GWG. METHODS: In this controlled trial, pregnant women (N = 16, mean age of 29.9 ± 4.3 years) with a gestational age

Introduction Among persons with mental health conditions, the impact of the COVID-19 pandemic on sleep health is underexplored. The present study investigated whether sleep changes related to the COVID-19 pandemic differed among individuals with mood and/or anxiety disorders compared to individuals without these disorders. Methods A 25-minute online survey, distributed globally to adults aged >18y through social media advertising from 5/28/2020-7/10/2020, examined the association of mental health diagnoses with COVID-19 related sleep changes. Participants reported prior history of mood and anxiety disorders, and pre-COVID-19 and current sleep patterns including bedtime, wake time, total sleep time (TST), sleep efficiency (SE:[TST/time in bed*100%], and nightmare frequency/wk. ANOVA models comparing mental health disorder groups (no diagnoses, mood disorders, anxiety disorders, mood and anxiety disorders) on mean differences in sleep changes were conducted. Results Among 1,048 participants, 71.5% reported no prior mood and/or anxiety disorders9.3% reported anxiety disorders only, 4.3% reported prior mood disorders only, and 14.9% reported both mood and anxiety disorders. There were significant group differences in total sleep time (F (3,670)=4.6, p=0.003) and sleep efficiency (F (3,670) =2.8, p=0.038) such that individuals with both mood and anxiety disorders experienced greater decreases in total sleep time (Mean Difference: 39.0min, SE=13.0) and sleep efficiency (Mean Difference=3.8%, SE=1.6) compared to individuals without any mood or anxiety disorders. In addition, the model for nightmare frequency per week was significant (F(3,654)=5.6, p=0.001) such that individuals with both anxiety and mood disorders (Mean Difference=1.1, SE=0.4) and individuals with mood disorders only (Mean Difference=1.1, SE=0.4) reported greater increases in nightmare frequency compared to participants without any mood or anxiety disorders. There were no group differences in bedtime and wake time. Conclusion Among a global sample, COVID-19 pandemic-related sleep health significantly worsened among individuals with prior mood and anxiety disorders relative to individuals without these disorders.
