Sheltering-in-place, social distancing, and other strategies to minimize COVID-19 transmission may impact physical activity (PA) and well-being in older adults. To assess self-reported PA changes, well-being, and priorities of older women across the USA early in the COVID-19 pandemic. In May 2020, a 10-question survey was emailed to 5,822 women, aged over 70 years, who had been assigned to the Women’s Health Initiative (WHI) Strong and Healthy (WHISH) trial PA intervention and had provided email addresses. The survey assessed general and physical well-being, current priorities, and PA levels before and during the COVID-19 pandemic. Demographic and physical function data were collected previously. Descriptive analyses characterized participants’ priorities and PA changes from before the pandemic to the time of data collection during the pandemic. Differences in PA change by age, physical function, and geographic region were assessed by Kruskal-Wallis and post hoc Dunn tests. Among 2,876 survey respondents, 89% perceived their general well-being as good, very good, or excellent, despite 90% reporting at least moderate (to extreme) concern about the pandemic, with 18.2% reporting increased PA levels, 27.1% reporting no changes, and 54.7% reporting decreased PA levels. Top priorities “in the midst of the COVID-19 outbreak” were staying in touch with family/friends (21%) and taking care of one’s body (20%). Among priorities related to physical well-being, staying active was selected most frequently (33%). Support for maintaining PA in older populations should be a priority during a pandemic and similarly disruptive events.

Physical activity improves quality of life and extends independence in older adults. Yet, how to motivate older adults to engage in physical activity is unclear. In the present study, 4108 older women, aged 70–99, reported how they motivated themselves to move when they did not feel like it, and their hours of physical activity and walking each week. Findings indicated that participants who endorsed more strategies had more hours of physical activity and walking. Strategic categories that correlated with more physical activity include focusing on the benefits and utilizing the surrounding environment to help motivate movement.

Objectives Omega-3 (n-3) polyunsaturated fatty acids (PUFAs) are essential in fetal growth and development and have been shown to modulate inflammatory processes throughout the lifespan. Previous studies have demonstrated that individuals with lower socioeconomic status (SES) may be at risk for low intake of n-3 PUFAs, however, no research has compared the concentrations of these nutrients present in maternal and cord serum between markers of SES. The purpose of this study is to assess the relationship between markers of SES and levels of n-3 PUFAs in maternal and cord serum in a group of patients delivering at a Midwest Academic Medical Center. Methods An IRB-approved study enrolled mother-infant pairs (n = 55) at the time of delivery for collection of maternal and cord serum samples. n-3 PUFA levels quantified included Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA), and total n-3 PUFAs. Markers of SES include private vs public insurance, income ≤ 150% of the poverty line vs > 150%, and college degree earners vs no college degree. The Mann-Whitney U test was used to assess differences in n-3 PUFA levels between SES groups. A P < 0.05 was considered statistically significant. Results Median gestational age at delivery was 39.3 weeks. Significantly higher nutrient levels were present in college-educated mothers vs less than college-educated mothers in median maternal EPA (9.44 µg/mL vs 5.13 µg/mL, p = 0.010), cord EPA (1.88 µg/mL vs 1.40 µg/mL, p = 0.011), cord DHA (37.96 µg/mL vs 32.80 µg/mL, p = 0.014), and total cord n-3 PUFAs (44.23 µg/mL vs 39.34 µg/mL, p = 0.024). Median cord EPA levels were significantly higher in those with private insurance compared to public (1.79 µg/mL, 1.18 µg/mL, p = 0.022). Additionally, median cord EPA levels were significantly higher in those > 150% the poverty line (1.79 µg/mL, 1.10 µg/mL, p = 0.030). Conclusions Our findings suggest that individuals with lower SES may be at risk for lower serum levels of n-3 PUFAs in pregnancy, which could increase their susceptibility to adverse birth and pregnancy outcomes. Future studies should focus on replicating these results in a larger, more heterogeneous sample and should consider analyzing additional markers of SES.

Objectives Vitamin E is a fat-soluble nutrient with four isoforms: α-, β-, δ-, and γ-tocopherol. These isoforms differentially modulate inflammation and are related to important perinatal outcomes such as preterm delivery and Apgar scores. Understanding the dietary consumption of these isoforms and their respective prevalence in biological samples is an important component to optimize nutritional recommendations. The purpose of this study is to compare tocopherol isoform proportions among maternal, cord, and neonatal plasma; maternal breast milk; and maternal dietary intake. Methods Samples of maternal breast milk and maternal, cord, and neonatal plasma were obtained within 1 month following delivery for maternal-infant dyads (N = 17) from the neonatal intensive care unit. Maternal dietary intake was assessed using the Harvard Willett Food Frequency Questionnaire. Relative proportions of α-, δ-, and γ-tocopherol in each sample type were measured and median tocopherol concentrations were compared using Kruskal-Wallis tests. A p-value < 0.05 was statistically significant. Results Total tocopherol concentrations were significantly different across sample groups (P < 0.001). Concentrations were highest in maternal serum, followed by neonatal serum, maternal breast milk, and umbilical cord serum. In all samples, α-tocopherol had the highest relative proportion, followed by γ- and δ-tocopherol, respectively. Compared to all biological samples, the dietary intake proportion of γ-tocopherol was significantly higher (P < 0.001), while the proportion of α-tocopherol was significantly lower (p = 0.04). Conclusions We observed significant differences in tocopherol concentrations across related biological samples, with maternal plasma containing the highest concentration and umbilical cord plasma the lowest. Mothers also consumed significantly higher percentages of γ-tocopherol than those found in both their plasma and breast milk. This suggests that proportions of individual tocopherol isoforms are influenced by factors other than dietary intake. Additional research should explore these associations in a larger cohort and analyze the effects of supplementation on tocopherol concentrations.
