Objective Stay‐at‐home orders in response to the COVID‐19 pandemic have forced abrupt changes to daily routines. This study assessed lifestyle changes across different BMI classifications in response to the global pandemic. Methods The online survey targeting adults was distributed in April 2020 and collected information on dietary behaviors, physical activity, and mental health. All questions were presented as “before” and “since” the COVID‐19 pandemic. Results In total, 7,753 participants were included. The sample included 32.2% of individuals with normal weight, 32.1% overweight, and 34.0% had obesity. During the pandemic, overall scores for healthy eating increased (p<0.001), due to less eating out and increased cooking ( p <0.001). Sedentary leisure behaviors increased while time spent in physical activity (absolute time and intensity‐adjusted) declined (p<0.001). Anxiety scores increased 8.78±0.21 during the pandemic and the magnitude of increase was significantly greater in people with obesity (p≤0.01). Weight gain was reported in 27.5% of the total sample compared to 33.4% in participants with obesity. Conclusions The COVID‐19 pandemic produced significant health effects, well beyond the virus itself. Government mandates together with fear of contracting the virus have significantly impacted lifestyle behaviors alongside declines in mental health. These deleterious impacts have disproportionally affected individuals with obesity.
PurposeThe spread of COVID-19 and the associated stay-at-home orders and shutdowns of gyms and fitness centers have drastically influenced health behaviors leading to widespread reductions in physical activity (PA). The recent Call to Action from the American College of Sports Medicine has promoted “innovative strategies to promote PA during the COVID-19 pandemic.” We aimed to identify individual-level factors that protected against declines in PA levels amid the COVID-19 restrictions.MethodsWe used the Pennington Biomedical COVID-19 Health Behaviors Survey for our analyses and used mixed-effect linear and generalized linear models to estimate the effects of individual-level factors on changes in PA levels during the COVID-19 restrictions.ResultsParticipants (n = 4376) provided information on PA behaviors before and during the COVID-19 shutdown. Overall, PA levels declined by a mean ± SD of 112 ± 1460 MET·min·wk−1 during the COVID-19 shutdown; however, changes in PA were heterogeneous, with 55% of the participants reporting increases in or maintenance of PA during that time. Several social and demographic factors were significantly related to declines in PA, including high prepandemic PA levels, living alone (difference = 118 MET·min·wk−1), low household income (difference between the highest and the lowest income group = 363 MET·min·wk−1), COVID-19-related changes in income (difference = 110 MET·min·wk−1), and loss of employment (difference = 168 MET·min·wk−1). The substitution of prepandemic gym attendance with the purchase and use of home exercise equipment or exercise through virtual fitness platforms promoted increases in PA during the COVID-19 shutdown.ConclusionsWhile promoting PA through the COVID-19 pandemic, it is important to consider demographic factors, which greatly influence health behaviors and implementation of, and access to, replacement behaviors. The promotion of such strategies could help maintain PA levels during potential future stay-at-home orders.
Calorie restriction (CR), the reduction of dietary intake below energy requirements while maintaining optimal nutrition, is the only known nutritional intervention with the potential to attenuate aging. Evidence from observational, preclinical, and clinical trials suggests the ability to increase life span by 1–5 years with an improvement in health span and quality of life lived. CR moderates intrinsic processes of aging through cellular and metabolic adaptations and reducing risk for the development of many cardiometabolic diseases. Yet, implementation of CR may require unique considerations for the elderly and other specific populations. The objectives of this review are to summarize the evidence for CR to modify primary and secondary aging; present caveats for implementation in special populations; describe newer, alternative approaches that have comparative effectiveness and fewer deleterious effects; and provide thoughts on the future of this important field of study.

Body Dissatisfaction (BD) and low physical self-concept and exercise efficacy have been linked to poor physical fitness levels and adverse health outcomes in children. The purpose of this study was to examine the relationship between BD, physical fitness, exercise self-efficacy, and self-Perception of Physical Fitness (PFP) in Latina and Black female children. Twenty-eight Latina and Black children enrolled in an elementary afterschool program, aged 8–12, completed surveys evaluating body dissatisfaction, exercise efficacy, PFP, and measures of physical fitness. Subjects exhibited moderate but significant inverse relationships between BD and PFP in strength (r = −0.459), agility (r = −0.382), aerobic fitness (r = −0.354), and flexibility (r = −0.461) (p < 0.05 for all). There was a significant negative correlation between exercise efficacy and BD (r = −4.2; p < 0.05). Power (r = 0.51) and flexibility (r = 0.42) were the only physical fitness measures significantly and positively related to children’s PFP (p < 0.05). A significant medium inverse relationship was also found between BD and aerobic fitness scores (r = −0.381; p < 0.05). However, after controlling for exercise efficacy or perception of physical fitness, the relationship between BD and aerobic fitness was not significant (p > 0.05). Findings suggest that positive PFP and positive performance in several physical fitness measures are associated with lower levels of BD in minority female children. Furthermore, evidence suggests exercise efficacy and PFP can mediate the relationship body image and aerobic fitness. These findings suggest that PFP, more so than measured physical fitness, was associated with lower levels of BD in minority female children. These results have important implications for programs designed to improve physical fitness and mental health in minority children.
Understanding women’s perceptions of eating behaviors and dietary patterns can inform the ‘teachable moment’ model of pregnancy. Our objectives were to describe eating behaviors and dietary patterns in pregnancy. This was a cross-sectional, national electronic survey. Women were ≥18 years of age, living in the United States, currently pregnant or less than two years postpartum, and had internet access. Age, education, race, and marriage were included as covariates in ordinal and binary logistic regressions (significance p < 0.05). Women (n = 587 eligible) made positive or negative changes to their diets, while others maintained pre-existing eating behaviors. The majority of women did not try (84.9 to 95.1% across diets) and were unwilling to try (66.6 to 81%) specific dietary patterns during pregnancy. Concerns included not eating a balanced diet (60.1 to 65.9%), difficulty in implementation without family (63.2 to 64.8%), and expense (58.7 to 60.1%). Helpful strategies included being provided all meals and snacks (88.1 to 90.6%) and periodic consultations with a dietitian or nutritionist (85 to 86.7%). Responses differed across subgroups of parity, body mass index, and trimester, notably in women with obesity who reported healthier changes to their diet (p < 0.05). Our study underscores the importance of tailoring care early to individual needs, characteristics, and circumstances.
Background The maternal metabolic milieu is challenged during pregnancy and may result in unwarranted metabolic complications. A time-restricted eating (TRE) pattern may optimize the metabolic response to pregnancy by improving glucose metabolism and reducing circulating glucose concentrations, as it does in nonpregnant individuals. Objectives The objectives of this study were to 1) assess eating timing in pregnant women; 2) understand the perceptions of adopting a TRE pattern; 3) determine the barriers and support mechanisms for incorporating a TRE pattern; and 4) identify those most willing to adopt a TRE pattern during pregnancy. Methods This was a cross-sectional quantitative and quasi-qualitative online survey study for women who were pregnant at the time of study completion or had given birth in the prior 2 years. Group analyses were performed based off willingness to try a TRE pattern using chi-squared analyses, independent samples t-tests, or an analysis of variance. Three separate reviewers reviewed qualitative responses. Results A total of 431 women (BMI, 27.5 ± 0.3 kg/m2) completed the study. Of the participating women, 23.7% reported willingness to try a TRE pattern during pregnancy. Top barriers to adopting a TRE pattern during pregnancy were concerns for 1) safety; 2) nausea; and 3) hunger. The highest ranked support mechanisms were: 1) the ability to choose the eating window; 2) more frequent prenatal visits to ensure the health of the baby; and 3) receiving feedback from a dietician/nutritionist. Women who did not identify as White/Caucasian expressed a higher willingness to try a TRE pattern during pregnancy (P = 0.01). Women who were nulliparous expressed a higher willingness to try a TRE pattern (P = 0.05). Discussion TRE, an alternative dietary strategy shown to optimize metabolic control, may be effective to prevent and manage pregnancy-related metabolic impairments. To create an effective TRE intervention during pregnancy, the input of pregnant mothers is necessary to increase adherence and acceptability.
Physical activity during pregnancy is an important health behavior. However, many pregnant individuals are provided with little-to-no guidance to adequately engage in physical activity. The purpose of this quantitative and quasi-qualitative study of currently or previously pregnant women was to examine physical activity behaviors in pregnancy and understand barriers and facilitators to achieving physical activity recommendations. Overall, 431 women (18+ years), White/Caucasian (84.5%), married (84.9%), and currently pregnant (66.6%), completed an online survey study. Most women (69.4%) reported engaging in cardio-based physical activity and willing to engage in physical activity to meet guidelines between 2 and 5 days per week (77.4 –88.8%). The most frequently reported barriers were feeling too tired (72.8%) or uncomfortable (71.8%) and childcare needs (57.8%). Being able to choose time of day (96.0%), accessing home workouts (92.9%), and having a personalized prescription (95.6%) were the most reported facilitators. Open comment feedback resulted in additional barriers, such as ensuring proper energy intake, while motivation and support from other pregnant individuals were fundamental facilitators. Individualized physical activity prescription is lacking in routine prenatal care. To support pregnant individuals to achieve physical activity recommendations, developing a prescription with suitable modalities, at-home options, and consideration for physical activity timing are required.
