RESUMEN

Elite private universities have high stress levels, particularly for underrepresented populations. While physical activity and gratitude can both reduce stress, independent effects from gratitude and interaction effects between physical activity and gratitude on stress are insufficiently explored. Our study investigated these effects among undergraduates at elite private universities. Undergraduates (n = 145) completed an online survey in Fall 2022. Moderate-high physical activity levels were reported by 96.19% of the sample. No significant interaction effect between physical activity and gratitude was seen nor a significant main effect of physical activity on perceived stress. A significant main effect of gratitude on perceived stress [F (2, 99) = 16.732, p < .001, ω2 = .253] was found with higher perceived stress among participants with low compared to moderate (p = .001) or high gratitude (p < .001). Gratitude exerted an independent, significant effect on perceived stress among elite university undergraduates and could be used as an additional healthy coping mechanism along with physical activity to combat stress.

RESUMEN

Many university students experienced changes during the COVID-19 pandemic, including potential changes in physical activity (PA) levels and living situation. As PA behaviors in young adulthood help establish life-long habits and future health outcomes, the purpose of this study was to investigate overall change in PA, as well as change in PA due to living situation, among private university students during the COVID-19 pandemic. Private university students (n = 109) between 18 and 25 years of age completed an online survey that included the International Physical Activity Questionnaire - Short Form. T-tests examined changes in overall time spent in PA from before to during the COVID-19 pandemic, and the differences in MET-minute distributions between groups. Students performed significantly less activity during the COVID-19 pandemic than before (t(108) = 3.51, p = .001, d = 0.493), with 70.6% of all students meeting exercise recommendations before the pandemic and 51.4% after. Students living with vs. without a parent/guardian attained similar PA levels (t(107) = -.114, p = .910) before the pandemic (73.1% vs. 69.9%, respectively), but students living with a parent/guardian engaged in significantly less PA (t(107) = 2.04, p = .044, d = 0.475) than those living without a parent/guardian during the pandemic (37.5% vs. 57.1%, respectively). The declines in PA suggest the need for targeted interventions and education among private university students. In order to maximize the health benefits of PA, it is crucial that activity engagement return to at least pre-COVID-19 levels.

RESUMEN

Objective: This study assessed the impact of the COVID-19 pandemic on college students' nutrition, including dietary behaviors and food security status. Participants: Participants included 140 students between 18 and 25 years of age, who were enrolled in a college or university in the greater Houston area. Methods: Analyses included descriptive statistics, t tests, and ANOVAs to analyze differences in dietary behaviors by demographic variables, and chi-square tests to assess characteristics associated with food security status. Results: The majority of participants reported changing their diets due to the COVID-19 pandemic. There were no significant differences by demographics. However, there were significant differences in food security status by race/ethnicity and social class. Conclusion: This study identified changes and disparities in college students' dietary behaviors and food security status during the COVID-19 pandemic. Findings help inform future policy, programs, and research to address college students' nutrition during the ongoing COVID-19 pandemic.

RESUMEN

PURPOSE: Weight gain is common among breast cancer patients and may contribute to poorer treatment outcomes. Most programs target breast cancer survivors after the completion of therapy and focus on weight reduction. This study examined the feasibility and preliminary efficacy of an intervention designed to prevent primary weight gain among women receiving neoadjuvant chemotherapy for breast cancer. METHODS: Thirty-eight newly diagnosed stage II or III breast cancer patients were randomized to the BALANCE intervention or usual care within 3 weeks of starting neoadjuvant chemotherapy. The intervention used a size acceptance-based approach and encouraged home-based resistance and moderate-intensity aerobic exercise as well as a low energy-dense diet to prevent weight gain. Assessments were conducted at baseline, mid-chemotherapy (3 months), and post-chemotherapy (6 months). Intervention feasibility, acceptability, and preliminary effects on anthropometric, quality of life, and circulating biomarker measures were evaluated. RESULTS: Intervention participant retention (100%) and in-person session attendance (80%) were high during the intervention period, although attendance dropped to 43% for telephone-delivered sessions. The majority of participants reported being satisfied with the intervention during chemotherapy (88%). Participants in the intervention group had greater reductions in waist circumference (p = .03) and greater improvements in self-reported vitality scores (p = .03) than the control group at the end of chemotherapy. Significant effects on biomarkers were not observed. CONCLUSIONS: A size acceptance weight management program is feasible during neoadjuvant chemotherapy among breast cancer patients and may have beneficial effects on waist circumference and patient vitality. TRIAL REGISTRATION: This study was registered as a clinical trial at www.clinicaltrials.gov (NCT00533338).

RESUMEN

OBJECTIVE: Physical activity is beneficial for cancer survivors, but exercise participation is low in this population. It is therefore important to understand the psychological factors underlying exercise uptake so that more effective interventions can be developed. Social-cognitive theory constructs such as outcome expectancies predict exercise behavior, but self-report measures have several limitations. We examined the associations between implicit (automatic) cognitions and exercise behavior and self-efficacy in endometrial cancer survivors. METHOD: This was a longitudinal study to examine predictors of exercise behavior in female endometrial cancer survivors who all received an exercise intervention. Participants (N = 100, mean age of 57.0) completed questionnaires to assess self-report exercise-related measures (outcome expectancy and attitudes about and identification with exercise) and reaction time (RT) tasks to assess implicit exercise cognitions (expectancy accessibility, implicit attitudes about exercise, and implicit self-identification with exercise) at baseline and at 2, 4, and 6 months at follow-up. Exercise behavior was measured using accelerometers and self-report. Data were analyzed using linear mixed models. RESULTS: Expectancy accessibility was associated with exercise duration independent of the corresponding self-report measure. Exercise implicit attitudes and self-identification were prospectively associated with exercise self-efficacy only after adjustment for the corresponding self-report measures and baseline self-efficacy. Self-report measures were also associated with study outcomes. CONCLUSIONS: Both self-reported cognitions and implicit cognitions may be useful to identify individuals at risk of failing to exercise. Individuals so identified might be provided with a different or more intensive intervention. The data also suggest cognitive targets for intervention. (PsycINFO Database Record

RESUMEN

OBJECTIVE: This study evaluated whether social-cognitive theory (SCT) variables, as measured by questionnaire and ecological momentary assessment (EMA), predicted exercise in endometrial cancer survivors. METHOD: One hundred posttreatment endometrial cancer survivors received a 6-month home-based exercise intervention. EMAs were conducted by using hand-held computers for 10- to 12-day periods every 2 months. Participants rated morning self-efficacy and positive and negative outcome expectations by using the computer, recorded exercise information in real time and at night, and wore accelerometers. At the midpoint of each assessment period, participants completed SCT questionnaires. Using linear mixed-effects models, the authors tested whether morning SCT variables predicted minutes of exercise that day (Question 1) and whether exercise minutes at time point Tj could be predicted by questionnaire measures of SCT variables from time point Tj-1 (Question 2). RESULTS: Morning self-efficacy significantly predicted that day's exercise minutes (p < .0001). Morning positive outcome expectations were also associated with exercise minutes (p = .0003), but the relationship was attenuated when self-efficacy was included in the model (p = .4032). Morning negative outcome expectations were not associated with exercise minutes. Of the questionnaire measures of SCT variables, only exercise self-efficacy predicted exercise at the next time point (p = .003). CONCLUSIONS: The consistency of the relationship between self-efficacy and exercise minutes over short (same day) and longer (Tj to Tj-1) time periods provides support for a causal relationship. The strength of the relationship between morning self-efficacy and exercise minutes suggest that real-time interventions that target daily variation in self-efficacy may benefit endometrial cancer survivors' exercise adherence.

RESUMEN

Physical activity has been shown to benefit cancer survivors' physical functioning, emotional well-being, and symptoms. Physical activity may be of particular benefit to survivors of endometrial cancer because they are more likely to be obese and sedentary than the general population, as these are risk factors for the disease, and thus experience a number of related co-morbid health problems. However, there is little research systematically studying mechanisms of physical activity adherence in cancer survivor populations. This paper describes the design of the Steps to Health study, which applies a Social Cognitive Theory-based model of endometrial cancer survivors' adoption and maintenance of exercise in the context of an intervention to increase walking or other moderate intensity cardiovascular activity. In Steps to Health we will test the influence of self-efficacy and outcome expectations on adherence to exercise recommendations, as well as studying the determinants of self-efficacy. Endometrial cancer survivors who are at least 6 months post-treatment are provided with an intervention involving print materials and telephone counseling, and complete assessments of fitness, activity, self-efficacy and outcome expectations, and determinants of self-efficacy every two months for a six month period. In addition to testing an innovative model, the Steps to Health study employs multiple assessment methods, including ecological momentary assessment, implicit tests of cognitive variables, and ambulatory monitoring of physical activity. The study results can be used to develop more effective interventions for increasing physical activity in sedentary cancer survivors by taking into account the full complement of sources of self-efficacy information and outcome expectations.

RESUMEN

OBJECTIVE: The physical and psychological benefits of exercise for cancer survivors are well documented. Researchers have examined self-efficacy (SE) as a target for promoting exercise; however, the predictors of SE, including treatment factors and comorbidities, have not been examined extensively. The purpose of this cross-sectional analysis was to examine how variables related to cancer and cancer treatment, comorbid health problems, health-related quality of life (QOL), and depression relate to SE for physical activity in cancer survivors. METHODS: This secondary analysis examined treatment factors, comorbidity, and QOL data from 148 breast cancer and 134 prostate cancer survivors who had participated in studies examining exercise and QOL. A predictive regression model was developed by testing each variable individually with SE and including the variables that had a significance of

RESUMEN

Studies have shown that expectations about exercise outcomes are associated with exercise behavior. Outcome expectations can be assessed by self-report questionnaires, but a new method-the expectancy accessibility task-may convey unique information about outcome expectations that is less subject to respondent biases. This method involves measuring the reaction time to endorse or reject an outcome We examined the relationship of self-reported outcome expectations and expectancy accessibility tasks in a pilot study of sedentary endometrial cancer survivors (N = 20). After measuring outcome expectations and expectancy accessibility, participants were given an exercise program and asked to monitor exercise for 7 days using diaries and accelerometers. Analyses revealed no relationship between outcome expectation scores and exercise, but shorter response times to endorse positive exercise outcomes was related to more exercise in the next week (p = .02).

RESUMEN

BACKGROUND: Many breast cancer survivors experience long term sequelae, including fatigue, decreased physical functioning, pain, and psychological distress. Physical activity can ameliorate these problems, but there is little research on how activity should be performed to be most beneficial. This study explores how dimensions of physical activity (total energy expenditure, frequency, and duration) are associated with symptoms among breast cancer survivors. METHODS: We conducted a secondary analysis of data on physical activity behavior and symptoms in a cross-sectional study (n = 148) of breast cancer survivors who were off treatment and had been diagnosed within the past 5 years. RESULTS: Multivariate analyses showed that total energy expenditure was associated with better general health (p = 0.006) and fewer depressive symptoms (p = 0.014), while frequency of activity was linearly related to physical functioning (p = 0.047), pain (0.057), general health (p < 0.001), and depressive symptoms (p < 0.001). Duration was related to physical functioning, pain, and general health, but the worst outcomes were reported by the participants with the shortest and longest duration of activity (quadratic trend p values = 0.002, 0.003, 0.008, respectively). DISCUSSION/CONCLUSIONS: Greater total energy expenditure, higher physical activity frequency, and moderate duration were associated with better outcomes for most symptoms, although there was no relationship between any of the dimensions of physical activity and fatigue. IMPLICATIONS FOR CANCER SURVIVORS: The association of better outcomes with higher energy expenditure, higher frequency of activity, and moderate duration indicates that increasing activity through multiple short bouts may be the most beneficial for breast cancer survivors. However, randomized studies are needed to confirm this finding.
