Examination of eating competence in a geo-diverse sample with metabolic syndrome.

Eating competence (EatC) is an intra-individual approach to eating attitudes and behaviors associated with greater well-being. EatC research has not included persons with confirmed metabolic syndrome (MetS). Therefore, EatC of persons with MetS was explored to identify unique associations and inform implementation of MetS lifestyle interventions using baseline data from a multisite, randomized trial of a 2-year lifestyle intervention with MetS. EatC, measured with the Satter Eating Competence Inventory 2.0 (ecSI 2.0™), was examined for relationships with bioclinical measures (e.g., blood pressure, lipids), medication use, BMI, waist circumference, fruit/vegetable intake, and psychosocial factors, (e.g., stress, mindfulness). Data were collected in person and video call by trained research personnel. EatC was examined as a continuous score and as a categorical variable with ecSI 2.0™ scores ≥ 32 considered eating competent. Participants (n = 618) were predominantly female (76%), White (74%), college educated (60%). Mean age was 55.5 ± 11 y. Mean ecSI 2.0™ was 29.9 ± 7.4 and 42% were eating competent. EatC was greater for males, persons who were older and food secure. Competent eaters (vs. non-eating competent) had lower waist circumference (112.7 ± 12.5 cm vs.116.8 ± 16.0 cm; P < 0.001) and BMI (35.0 ± 6.1 vs. 37.5 ± 7.3; P < 0.001). Serum triglycerides, HDL-cholesterol, fasting blood glucose, HbA1c, and blood pressure did not differ by EatC status. Compared to non-eating competent persons, competent eaters perceived less stress, were more mindful, indicated better physical function, and more habitual vegetable intake (all P < 0.001) and sensory awareness (P < 0.05). EatC in MetS paralleled the non-MetS profile. EatC was associated with a healthier psychosocial profile, waist circumference and BMI. Findings support further research to examine the mediational or moderating influence of EatC in the treatment of MetS.

Prolonged standing increases lower limb arterial stiffness.

PURPOSE: Standing workstations have recently been promoted as a healthy alternative to sitting. However, it is unknown how prolonged standing affects arterial stiffness, a prognostic indicator of cardiovascular health. The purpose of this study was twofold: to observe changes in arterial stiffness, as assessed by pulse wave velocity (PWV), with a 2-h bout of standing, and to determine if short, intermittent walking bouts provide a comparative advantage to standing alone. METHODS: Nineteen adults had arterial stiffness assessed by pulse wave velocity. Central (CPWV), upper peripheral (UPWV), and lower peripheral (LPWV) PWV were assessed before (supine), during standing (min 10, 60, and 120), and after (supine) the 2-h standing bout. In one trial, the participants stood at a standing desk immobile for 2 h. In the other trial, participants performed 5-min walking breaks after every 25 min of standing. RESULTS: After 2-h of standing, supine (85.8 ± 90.1 cm/s) and standing (303.4 ± 390.2 cm/s), LPWV increased independent of trial (i.e., main effect of time; p < 0.001). Walking breaks during 2 h of standing did not significantly attenuate these changes. In addition, standing CPWV decreased over time (- 38.5 ± 61.5 cm/s; p = 0.04). Yet, UPWV, standing or supine, did not change over the course of standing (p > 0.05). CONCLUSIONS: These findings indicate that prolonged standing increases the measures of arterial stiffness and there is no evidence that walk breaks attenuate this response.

Relationships between personality traits, high school sports participation, and physical activity of college students in the United States.

Objective: The study aimed to 1) examine relationships between contexts of PA, personality traits, and high school sports participation (sports) and 2) determine significant PA correlates in a college population. Participants: 237 undergraduates at a university in the United States between September 2020 and May 2021 participated. Methods: Participants completed a survey evaluating PA, personality traits, sports, and demographic variables. Pearson partial correlations assessed correlations between different PA domains, personality traits, and sports. Conscientiousness was positively associated with all PA measures (r = .14-.30), except for active transport PA. Sports were related to vigorous and leisure PA. Conscientiousness is related to PA measures and is a significant PA correlate. However, more research is necessary to understand if leisure time PA can enhance Conscientiousness.

Relationships between grit, physical activity, and academic success in university students: Domains of physical activity matter.

ObjectiveTo examine the relationships between contexts of physical activity, grit, and GPA in a college population.Participants:875 Undergraduate students from a large, southern university participated between October 2018 and March 2020.Methods:Participants completed an electronic survey evaluating physical activity and grit. The university provided official GPAs. Multiple linear regression models evaluated the correlations between grit, the different physical activity domains, and GPA.Results:Grit was positively associated with domestic physical activity, leisure time physical activity, and GPA. Consistency of interest had no associations with the domains of physical activity or GPA. Perseverance of effort was positively associated with walking, active transport physical activity, domestic physical activity, leisure physical activity, and GPA.Conclusion:Perseverance of effort is related to different domains of physical activity and GPA. Future studies should investigate if increasing leisure time physical activity causes increases in perseverance of effort.

Relationships between physical fitness, health behaviors, and occupational outcomes in students, faculty, and staff of an American university.

OBJECTIVE: This study examined relationships between physical fitness, health behaviors, and occupational outcomes of university affiliates. PARTICIPANTS: 166 university affiliates of an American university (including students, faculty, and staff) participated between October 2018 and March 2020. METHODS: Participants completed fitness measurements, wore a device to measure physical activity (PA) and sleep for one week, and completed a survey evaluating happiness and job satisfaction. Multiple regression models evaluated associations between physical fitness, health behaviors, and occupational outcomes. RESULTS: 45% of participants had "poor" cardiorespiratory fitness (CRF) and unhealthy % fat. CRF, body composition, and muscular endurance were related to PA while body composition was related to sleep duration. Muscular endurance was related to GPA and job satisfaction. CONCLUSIONS: Findings suggest 45% of university affiliates had deficient physical fitness and may benefit from increasing PA and sleep. Universities should evaluate fitness within holistic programs to improve affiliates' health and, ultimately, occupational success.

Health Educator Participation in Virtual Micro-Credentialing Increases Physical Activity in Public Health Competencies.

Background: Physical activity is an important component of leading a healthy life. Public health is one of the nine major sectors for disseminating information about physical activity and increasing the physical activity of the general public. Purpose: Increase competency among Cooperative Extension agents (i.e., public health workers) on selecting, delivering, and evaluating physical activity programs through a theory-based online training program. Methods: Cooperative Extension agents from two states were invited to participate via statewide listservs. Participants were invited to attend sessions, complete competency checks, and between-session assignments each week. The study was conducted using a video conferencing platform. The intervention was 9 weeks from June to July 2020 and had 130 participants. Pre- and post-program surveys included physical activity competencies and validated scales for flourishing and physical activity status. Data for competencies pre and post were analyzed using the Wilcoxon signed rank test, p < 0.01. Physical activity and flourishing pre and post were compared using t-tests, p < 0.05. Results: Physical activity in public health competency increased significantly (p < 0.00) as did agents' personal physical activity levels (p < 0.05). Changes in flourishing were not significant (p < 0.09) but trended in the hypothesized direction. Conclusions: The online competency-based training program significantly improved Cooperative Extension agents' knowledge of physical activity guidelines and physical activity program implementation. Future work is needed related to the scalability of the training program.

Promoting Physical Activity Through Youth Sports Programs: It's Social.

Youth sport is a key physical activity opportunity for children and adolescents. Several factors influence youth sport participation, including social factors, but this has not to date been clearly delineated. This study is a scoping review to survey the literature on the influence of family and peers on youth sports participation. The review identified 111 articles of which the majority were cross-sectional, included boys and girls, and were conducted primarily in the United States, Canada, Australia, and the United Kingdom. The articles were grouped into 8 research themes: (1) reasons for participation, (2) social norms, (3) achievement goal theory, 4) family structure, (5) sports participation by family members, (6) parental support and barriers, (7) value of friendship, and (8) influence of teammates. Friendships were key to both initiation and maintenance of participation, parents facilitated participation, and children with more active parents were more likely to participate in sport. Less is known on how family structure, sibling participation, extended family, and other theoretical frameworks may influence youth sport. The review suggests that social influences are important factors for ensuring participation, maximizing the quality of the experience, and capitalizing on the benefits of youth sport. Future research studies, programs, and policies promoting and developing evidence-based youth sporting experiences should consider social influences on youth sport participation.

Walking breaks can reduce prolonged standing induced low back pain.

Standing is commonly recommended to reduce sedentary behavior in the workplace; however, constrained prolonged standing has also been linked to musculoskeletal symptoms, such as low back pain (LBP). Light physical activity breaks, such as walking, may change lumbar spine posture enough to reduce LBP during standing. This study assessed the effectiveness of inserting 5-minute walking breaks every 25 min for reducing prolonged standing-induced LBP development. Nineteen participants completed two bouts of standing lasting 2 h - one with a 5-minute walking break every 25 min and one with no breaks. Pain measures were completed throughout the trial to categorize participants as pain developers (PDs) or non-pain developers (non-PDs). Lumbar region kinematics angle and range of motion were measured continuously. In standing, 58% (11/19) of participants were PDs, compared to just 26% when walking breaks were inserted. Seventy-three percent (8/11) were categorized as non-PDs with walking breaks. Median lumbar flexion increased during walking compared to standing. Lumbar region range of motion in the coronal and transverse planes also increased during walking. The intermittent lumbar flexion may help decrease LBP during prolonged standing. These results demonstrate that walking breaks may help promote lumbar movement and reduce prolonged standing-induced LBP.
