Gender differences in college student physical activity, and campus recreational facility use, and comfort

Comparisons of physical activity, sitting time, and substance use among college students before and during the COVID-19 pandemic

Objective: To compare physical activity (PA), sitting time, and substance use pre-COVID-19 and during COVID-19 pandemic among US college students. Participants: 484 students from a large Western university (20.6 ± 1.4 years, 80.0% female) were recruited. Methods: Self-reported online surveys were completed in June-August 2020. T-tests and non-parametric analyses were conducted for continuous and ordinal variables respectively. Results: Vigorous PA, moderate PA, and light PA decreased significantly by 32%, 27%, and 21% and sitting time increased significantly by 49% from pre-COVID-19 to during COVID-19 pandemic. Wine consumption was less during COVID-19 than pre-COVID-19 among female, non-first-generation, and White students. Sleep aids use was more frequent during COVID-19 than pre-COVID-19 pandemic among non-first-generation and White students. Conclusion: COVID-19 pandemic may influence college students' health behaviors including physical activity patterns, sitting time, and substance use. Effective health promotion and coping strategies should be widely available to college students during times of change and uncertainty.

Influence of living settings on physical activity levels and volition in exercise in male and female university students

This study explored the influence of living settings on physical activity (PA) levels and volition in exercise and their correlation, considering sex differences. Five hundred and sixty-six university students (261 rural and 305 urban) from Calabria region (Italy) attending universities courses filled an online survey where Global Physical Activity Questionnaire and Volition in Exercise Questionnaire were administered. Rural females (RF) showed lower PA levels and self-confidence than rural males (RM) (p<0.01). Postponing training and unrelated thoughts were higher in RF than RM (p<0.01 and p<0.05 respectively). PA levels, self-confidence and coping with failure were lower in urban females (UF) than urban males (UM) (p<0.01), Postponing training and unrelated thoughts were higher in UF than UM (p<0.01 and p<0.05). In RF and UF, PA levels positively correlated with self-confidence (Rho = 0.397) and coping with failure (Rho = 0.330), whereas negatively correlated with postponing training (Rho = -0.487) and unrelated thoughts (Rho = -0.283). In RM and UM, PA levels positively correlated with self-confidence (Rho = 0.270) and coping with failure (Rho = 0.258), whereas it negatively correlated with postponing training (Rho = -0.285). PA levels positively correlated with reasons (Rho = 0.260) only in UM. We showed for the first time the relationship between PA and volition factors considering the living setting in university students. Sex differences were observed in some volition facilitators and PA levels independently by the living context.

Mindful Self-Hypnosis Combined with Resistance Training to Reduce Perceived Stress and Improve Other Psychological Factors in Female College Students

Perceived stress is a significant problem among female college students that can impact psychological distress, sleep, and overall well-being. Mindful self-hypnosis (MSH) and resistance training (RT) have both been shown to reduce perceived stress. The rationale for the present study was to investigate whether MSH combined with RT could be more effective at reducing perceived stress as measured by the Perceived Stress Scale than RT alone due to synergistic effects achieved by combining the interventions. Forty-four female college students were randomized to one of the three groups: MSH+RT, RT only, or a wait-list control (WLC). Results indicated that, compared to RT only, the addition of MSH led to pronounced improvements in perceived stress which was significantly greater than WLC. Also, MSH+RT resulted in significant increases in mindfulness, sleep, strength, and well-being in comparison to WLC. MSH+RT was shown to be feasible with highly satisfactory participant ratings. Future research should examine the MSH+RT intervention with a larger population and with older women who are more at risk for stress and declining strength.

Relationship Between Multiple Roles and Leisure-Time Physical Activities in Working-Age Women

BACKGROUND

Multiple role theory has proven effective in predicting variations in health, and a growing body of research has shown the importance of taking women's roles into account when analyzing physical activity levels. Nonetheless, researchers have yet to characterize the interaction between the various roles played by women and their physical activity.

PURPOSE

The objectives of this study were to elucidate the relationship between multiple roles and leisure-time physical activities (LTPAs) and to determine whether LTPA varies among women across different roles.

METHODS

Data were derived from the 2013 National Health Interview Survey database provided by the Health Promotion Administration of Taiwan's Ministry of Health and Welfare, which includes 5,147 working-age women. The current study focused on women aged 20-50 years. The roles considered in this study included living with a partner, living with children, and employment status. LTPA levels were categorized as regular, inactive, or insufficient based on the LTPA metabolic equivalent in the previous week. The associations among level of LTPA, multiple roles, and demographic characteristics were analyzed using multiple regression analysis.

RESULTS

We found single mothers with children to be more inactive than partnered mothers, and women living with a partner and those living with children were more likely to be inactive, whereas women working full-time were not at risk of inactivity. Women who assumed a larger number of roles were at a greater risk of inactivity. These findings are consistent with role strain theory.

CONCLUSIONS

Single mothers with children are more inactive than partnered mothers, and appropriate social support programs are necessary to reduce further disparities. Second, multiple demands on working-age women limit the time available for LTPAs, particularly among women living with a partner and children and engaged in full-time work. A physical activity intervention is a program or initiative designed to promote physical activity and improve health outcomes. We should develop and provide sustainable physical activity resources through the help of partners' housework to better promote physical activity intervention for working-age women.

Difference in Levels of Vitamin D between Indoor and Outdoor Athletes: A Systematic Review and Meta-Analysis

Vitamin D, its importance in different processes taking place in the human body, the effects of abnormal levels of this hormone, either too low or too high, and the need for supplementation have been extensively researched thus far. Variances in exposure to sunlight can cause vitamin D levels to fluctuate. Indoor activity can be a factor for these fluctuations and can lead to a decrease in vitamin D levels. We conducted a systematic review and meta-analysis aiming to identify whether indoor compared to outdoor training has a significant influence on vitamin D levels; we also performed subgroup analyses and multivariate meta-regression. The type of training has an impact on vitamin D levels that is influenced by multiple cofounders. In a subgroup analysis not considering cofounders, the mean serum vitamin D was 3.73 ng/mL higher in outdoor athletes, a difference which barely fails to achieve significance (p = 0.052, a total sample size of 5150). The indoor-outdoor difference is only significant (clinically and statistically) when considering studies performed exclusively on Asian athletes (a mean difference of 9.85 ng/mL, p < 0.01, and a total sample size of 303). When performing the analyses within each season, no significant differences are observed between indoor and outdoor athletes. To control for multiple cofounders (the season, latitude, and Asian/Caucasian race) simultaneously, we constructed a multivariate meta-regression model, which estimated a serum vitamin D concentration lower by 4.446 ng/mL in indoor athletes. While a multivariate model suggests that outdoor training is associated with slightly higher vitamin D concentrations when controlling for the season, latitude, and Asian/Caucasian race, the type of training has a numerically and clinically small impact. This suggests that vitamin D levels and the need for supplementation should not be decided based on training type alone.

Physical Activity and Sedentary Behavior in University Students–The Role of Gender, Age, Field of Study, Targeted Degree, and Study Semester

Background

Physical inactivity and sedentary behavior are modifiable risk factors for an unhealthy lifestyle in university students. The aim of this study was to identify subgroups among German university students with an increased risk for unhealthy behavior. For this purpose, differences in physical activity and sedentary behavior with respect to sociodemographic and study related factors were examined.

Methods

A total of 4,351 students participated in an online survey. The amount of physical activity (metabolic equivalent of task-min/week) and the sitting time (h/day) were assessed using the German short form of the International Physical Activity Questionnaire. Differences in gender and age as well as field of study, targeted degree and study semester were analyzed using a single factorial ANOVA with Tukey correction or a Welch-ANOVA with Games-Howell correction.

Results

For physical activity, significant differences were found for gender (F_{(2, 80.46)} = 17.79, p < 0.001, ηp2 = 0.009), for field of study (F_{(5, 1738.09)} = 7.41, p < 0.001, ηp2 = 0.01), and for study semester (F_{(1, 948.12)} = 5.53, p < 0.05, ηp2 =0.001), but not for age and targeted degree (p > 0.05). For sedentary behavior, significant differences were found for field of study (F_{(5, 3816)} = 5.69, p < 0.001, ηp2 = 0.01) and targeted degree (F_{(3, 3868)} = 3.94, p < 0.01, ηp2 = 0.003), but not for gender, age and study semester (p > 0.05).

Conclusion

Female students, students enrolled in “natural sciences, mathematics and informatics” and first year students appear to have an increased risk of an unhealthy lifestyle. Future research should identify barriers to and incentives of physical activity as well as reasons for high amounts of SB in sub-populations of university students. Suitable prevention and intervention programs are necessary.

Effects of Weight-Related Self-Stigma and Smartphone Addiction on Female University Students' Physical Activity Levels

Physical inactivity is a common health problem in female college students, and factors such as weight self-stigma and smartphone addiction may negatively impact physical activity in this population. The aim of the current study was to investigate the associations between these variables and identify the moderating effects of smartphone addiction between weight stigma and physical activity. Using a cross-sectional study, information on the level of physical activity in the past week, weight-related self-stigma, and smartphone addiction, as well as demographics, were collected via an online survey from 391 female college students in Taiwan. Participants in two groups of moderate to high and low physical activity were compared using a zero-order bivariate correlation in terms of independent variables. A moderated mediation model using Model 14 in the Hayes’ PROCESS macro with 1000 bootstrapping resamples was applied to assess moderation effects. There were significant differences in terms of weight status, smartphone addiction, and weight stigma between active and inactive groups (p < 0.001). All independent variables except for age were positively correlated (0.14 < r < 0.45). Multivariate regression models indicated that weight status was associated with weight stigma (odds ratio [OR] = 9.13, p < 0.001; 95% CI = 6.90, 11.35). Weight status (OR = 0.47, p = 0.03; 95% CI = 0.23, 0.93), weight stigma (OR = 0.96, p = 0.03; 95% CI = 0.922, 0.997), and smartphone addiction (OR = 0.11, p = 0.003; 95% CI = 0.03, 0.47) were associated with physical activity. The moderating role of smartphone addiction on the association between weight stigma and physical activity was also identified (OR = 1.05, p = 0.049; 95% CI = 1.0001, 1.1004). The moderating effect of smartphone addiction on the association between weight stigma and physical activity suggests that designing interventions to address the negative impacts of both weight stigma and smartphone addiction may help to improve physical activity in female college students.

Weightlifting for Children and Adolescents: A Narrative Review

The involvement of youth in the sport of weightlifting and the use of weightlifting methods as part of training for youth sport performance appears to be increasing. Weightlifting for children and adolescents has been criticized in some circles and is a controversial aspect of resistance training for young people. Although injuries can occur during weightlifting and related activities, the incidence and rate of injury appear to be relatively low and severe injury is uncommon. A number of performance, physical, and physiological variables, such as body composition, strength, and power, are improved by weightlifting training in children, adolescents, and young athletes. Manipulating program variables, when appropriate, can have a substantial and profound influence on the psychological, physiological, physical, and performance aspects of weightlifters. An understanding of the sport, scientific training principles, and musculoskeletal growth development is necessary to properly construct a reasonable and appropriate training program. A scientific background aids in providing an evidenced basis and sound rationale in selecting appropriate methods and directing adaptations toward more specific goals and enables the coach to make choices about training and competition that might not otherwise be possible. If weightlifting training and competition are age group appropriate and are properly supervised, the sport can be substantially safe and efficacious.
