Effects of medical school on mental health and sleep habits

BACKGROUND and OBJECTIVES: This study aims to define changes in anxiety and depression among medical students while evaluating the association of sleep habits and other risk factors, including exercise habits and a diagnosis of chronic disease. The effect of the COVID-19 pandemic was also evaluated. DESIGN: A cohort of first- and second-year medical students was evaluated longitudinally using survey methods to quantify changes from pre-medical school and summer break to each semester in medical school throughout years one and two. METHODS: Data was analyzed using Generalized Linear Mixed Models (GLMMs) on the numeric responses of General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Pittsburg Sleep Quality Index. Additional assessments evaluated exercise habits, chronic disease, and impact of COVID-19 Pandemic. RESULTS: Depression, anxiety, and sleep habits displayed a cyclical change that was associated with the academic cycle. The COVID-19 pandemic was never significant. Medical students who had a chronic disease diagnosis had increased severity. Exercise did not play a role. CONCLUSION: The main driver for depression, anxiety, and poor sleep quality was the academic cycle, while the COVID-19 pandemic did not have an impact on mental health.

Association between the recognition of muscle mass and exercise habits or eating behaviors in female college students

This study aimed to examine the association between muscle mass and perception of body shape, desired body shape, physical strength, exercise habits, and eating behaviors. Height, weight, and body composition in 270 female university students were measured. The questionnaire on body shape perception, desired body shape, dieting experience, current, and past exercise habits, exercise preference, and eating behaviors were administered. The analysis of covariance with body fat mass as the covariate found that the skeletal muscle index (SMI) was different among each group on each of body perception or desired body shape (all, p < 0.001). In the post hoc test on body shape perception, the SMI in “obese” was significantly more than that in “slim” (p < 0.001) and “normal” (p < 0.001). In the desired body shape, the SMI in “become thin” was more than that in “maintain as current shape” (p < 0.001). Further, a significant difference was found among the categories of diet experience, with body fat mass as the covariate. In the post hoc test, the SMI in “yes” was more than that in “no” (p < 0.001). These results indicate that not only body fat mass but skeletal muscle mass drives young females’ desire for thinness even with exercise advantages.

Long-term Effect of Regular Physical Activity and Exercise Habits in Patients With Early Parkinson Disease

Objective:Owing to the lack of long-term observations and/or comprehensive adjustment for confounding factors, reliable conclusions regarding long-term effects of exercise and regular physical activity in Parkinson’s disease (PD) have yet to be drawn. Here, using data from the Parkinson’s Progression Markers Initiative study that includes longitudinal and comprehensive evaluations of many clinical parameters, we examined the long-term effects of regular physical activity and exercise habits on the course of PD.Methods:In this observational cohort study, we primarily used the multivariate linear mixed-effects models to analyze the interaction effects of their regular physical activity and moderate-to-vigorous exercise levels, measured through the Physical Activity Scale for the Elderly questionnaire, on the progression of clinical parameters, after adjusting for age, sex, levodopa-equivalent dose, and disease duration. We also calculated bootstrapping 95% confidence intervals (CIs), and conducted sensitivity analyses using the multiple imputation method and subgroup analyses using the propensity score matching to match for all baseline background factors.Results:237 early PD patients [median (interquartile range); age, 63.0 (56.0–70.0) years; Male, 69.2%; follow-up duration, 5.0 (4.0–6.0) years] were included. Regular physical activity and moderate-to-vigorous exercise levels at the baseline did not significantly affect the subsequent clinical progression of PD. However, average regular overall physical activity levels over time were significantly associated with slower deterioration of postural and gait stability [standardized fixed-effects coefficients of the interaction term (βinteraction) = -0.10 (95% CI, -0.14 to -0.06)], activities of daily living [βinteraction = 0.08 (95% CI, 0.04 to 0.12)], and processing speed [βinteraction = 0.05 (95% CI, 0.03 to 0.08)] in PD patients. Moderate-to-vigorous exercise levels were preferentially associated with slower decline of postural and gait stability [βinteraction = -0.09 (95% CI, -0.13 to -0.05)] and work-related activity levels were primarily associated with slower deterioration of processing speed [βinteraction = 0.07 (95% CI, 0.04 to 0.09)]. Multiple imputation and propensity score matching confirmed the robustness of our results.Conclusions:In the long-term, the maintenance of high regular physical activity levels and exercise habits was robustly associated with better clinical course of PD, with each type of physical activity having different effects.Trial Registration Information:Clinicaltrials.gov (NCT01176565). A link to trial registry page is https://clinicaltrials.gov/ct2/show/NCT01141023.Classification of Evidence:This study provides Class II evidence that sustained increase in overall regular physical activity levels in patients with early Parkinson disease was associated with slower decline of several clinical parameters.

Associations of Exercise Habits in Adolescence and Old Age with Risk of Osteoporosis in Older Adults: The Bunkyo Health Study

We investigated effects of exercise habits (EHs) in adolescence and old age on osteoporosis prevalence and hip joint and lumbar spine bone mineral density (BMD). Body composition and BMD in 1596 people aged 65–84 years living in Bunkyo-ku, Tokyo, were measured using dual-energy X-ray absorptiometry. We divided participants into four groups by a combination of EHs in adolescence and old age: none in either period (None-None), only in adolescence (Active-None), only in old age (None-Active), and in both periods (Active-Active). Logistic regression models were employed to estimate multivariable-adjusted odds ratios (ORs) for osteoporosis determined by T-score (less than −2.5 SD) using the None-None reference group. In men, the combination of EHs in adolescence and old age was not associated with osteoporosis prevalence. However, the lumbar spine’s BMD was significantly higher in the Active-Active than the None-Active group (p = 0.043). In women, the Active-Active group had lower lumbar spine osteoporosis prevalence than the None-None group (OR 0.65; 95% CI, 0.42–1.00, p = 0.049). Furthermore, hip BMD was significantly higher in the Active-Active group than in the other three groups (p = 0.001). Older women with EHs in adolescence and old age had higher lumbar BMD and lower risk of osteoporosis.

Traditional martial arts and shooting training have different effects on auditory fine structure processing ability---Evidence from behavioral tests and fMRI

Explore the influence of traditional martial arts and shooting training on the ability of auditory temporal fine structure (TFS) processing. Twenty-five college students participated in the experiment, including 8 traditional martial arts practitioners, 8 high-level shooting athletes, and 9 control groups without any regular exercise habits. The BIC (break in interaural correlation) delay threshold and TFS1 test were used to evaluate the temporary storage capacity and sensitivity of TFS, respectively, and a fMRI test was performed after the test. The results found that the traditional martial arts group had stronger TFS sensitivity, while the shooting group had stronger TFS retention ability, and the performance of the behavioral test of the shooting group is related to the fALFF value of the brain area of interest. Traditional martial arts and shooting training have improved the ability of auditory information processing from different angles, diversified exercise habits will lead to the development of diversity in brain structure and function.

Hubungan Antara Status Gizi Dan Kebiasaan Berolahraga Dengan Nilai Volume Oksigen Maksimal (VO2 Max) Pada Siswa Laki - Laki SMP Negeri Di Temanggung Selama Pandemi Covid-19

The negative impacts of the Covid-19 pandemic include anxiety, stress, reduced appetite, boredom, and physical fitnessproblems. These conditions certainly affect the nutritional status and also the cardiorespiratory fitness of a person. InIndonesia, at least 15 out of 1000 people, or around 2,784,064 individuals suffer from heart disease. In Central JavaProvince, 0.61% of them are children aged 5-14 years old (Riskesdas, 2018). The VO2 Max value is a method formeasuring cardio respiration that can be used to determine which children are at risk of suffering from cardiovasculardisease. The VO2 Max value is influenced by several factors, including nutritional status and exercise habits. Thisstudy aimed to find out the correlation between nutritional status and exercise habits and the value of maximum oxygenvolume (VO2 Max) in male students at SMP Negeri in Temanggung during the Covid-19 pandemic. This was adescriptive-analytic study with across-sectional design. The sampling was done using the purposive sampling methodon 57 samples at SMP Negeri 1 Kaloran. It used Chi-square test for nutritional status variable with p value = 0.000 andexercise habits with p value = 0.001. The logistic regression test was used for each p-value with the nutritional statusOR value of 6.640 and the exercise habit OR value of 4.807 and with R Square value of 0.38 or 38%. There was acorrelation between nutritional status and exercise habits and the value of maximum oxygen volume (VO2 Max) inmale students at SMP Negeri in Temanggung during the Covid-19 pandemic.

Investigating the impact of COVID-19 on performance and image enhancing drug use

Background Emerging research has suggested that the COVID-19 pandemic has had some impact on substance use patterns. The aim of the study was to conduct a rapid survey to assess the impact of COVID-19 on performance and image enhancing drug (PIED) use and training, and any subsequent negative physical or mental health outcomes. Methods During 2020, a convenience sample of 60 PIED consumers (mean age = 26.69; 68.3% located outside Australia) completed a quantitative anonymous online survey exploring how the coronavirus pandemic impacted patterns of PIED use and associated exercise habits. The survey was administered via the Qualtrics platform and distributed online through PIED forums as well as through the investigators’ networks. Participants were asked about their PIED use and exercise habits prior to and during restricted movement ‘lockdowns’. Results During pre-COVID, the majority of the sample opted to ‘blast-cruise’ (an initial high dose, followed by a lower maintenance dose; 71.7%, n = 43). During lockdown, 45% (n = 27) reported a change in PIED use as a result of the restrictions. In light of health concerns during COVID-19, a majority of men (60%, n = 36) did not take any extra precautions relating to their PIED use. A subgroup of men ceased using PIEDs completely (16.7%, n = 10) with the majority (80%, n = 8) of that subgroup following post-cycle therapy (PCT) of some kind. Only a small proportion of the sample reported negative mental health issues as a result of PCT access issues. Conclusions This study contributes to the emerging literature of the impact of the COVID-19 pandemic on substance use, specifically PIED use among men. The results suggest that the pandemic did influence the choice of PIEDs that participants consumed, although there was little disruption to patterns of exercise, an important aspect of PIED use. Of the men who did cease use completely, the majority reported little issue with PCT access; those who reported difficulty accessing PCT compounds indicated experience some mental health concerns related to ceasing their PIED use. Clinicians and those who come into contact with this group should be alert for any negative physical or mental health concerns resulting from disrupted or ceased PIED use.
