Physical exercise frequency and cognition: a multicenter cross-sectional cohort study.

ABSTRACT:

Background and aims

Dementia imposes a heavy burden on society and families, therefore, effective drug treatments, exploring and preventing factors associated with dementia, are paramount. To provide reference points for the best frequency of physical exercise (physical exercise), we investigated the association between frequency of PE and cognition in Chinese old adults.

Methods

16,181 Chinese participants aged 65 years or older were included in this study. Associations between PE and cognition were estimated multivariate logistic and linear regression analyses. Associations were further investigated across dementia subtypes (Alzheimer dementia, vascular dementia, and other types of dementia). Subgroup analyses were performed in different age groups, in populations with and without stroke, and those with and without hypertension.

Results

PE associated with dementia after adjusting for full covariates (OR: 0.5414, 95% CI: 0.4536-0.6491, p < 0.001). Exercise performed at ≥3 times/week associated with lower risk of dementia (OR: 0.4794-0.6619, all p value <0.001). PE was associated with improved cognition (β: 12851, p < 0.001), and any PE frequency contributed to cognitive improvement (p values for exercise performed ≥1 time/week were <0.001). Similar conclusions were identified when we repeated analyses in different dementia subtypes and age groups. Subgroup analyses suggested that the cognition of individuals without hypertension also benefitted from exercising 1-2 times/week (OR: 0.6168, 95% CI: 0.4379-0.8668, p = 0.005).

Conclusion

The best exercise frequency is exercising ≥3 times/week for individuals from different dementia subtypes and age groups. While for those without hypertension, PE at 1-2 times /week is also beneficial.

Project description:IntroductionMany health organizations have promoted the importance of the health-related benefits of physical fitness and physical activity. Studies have evaluated effective public health practice aiming to understand the cognition of physical activity among youths and adolescents. However, studies investigating the level of cognition and knowledge of physical fitness among Asian adults are lacking.PurposeThis study aimed to investigate the self-awareness level of physical fitness and exercise prescription and the demand for physical fitness assessment among Taiwanese adults.MethodsIn January-July 2019, a cross-sectional anonymous survey was conducted using Research Electronic Data Capture to gather data on demographic data, cognition investigation of physical fitness and exercise prescription, cognitive test of physical fitness and exercise prescription, and demand for physical fitness assessment.ResultsThe questionnaire was answered by 200 respondents. The rating for cognition investigation of physical fitness was 2.63-3.13 (unclear to mostly clear) and for exercise prescription was 2.05-2.76 (unclear) (rated on a 5-point Likert scale). Results show that lack of awareness was highest for health-related physical fitness, exercise prescription, and exercise progress planning. 98% of subjects did not know the latest recommended guidelines for physical activity, despite most agreeing that physical fitness and exercise are good for health. Most subjects (72%) indicated a willingness to accept self-pay service for physical fitness assessments.ConclusionsThis is the first study to report on the demand for cognition, assessment, and promotion of physical fitness among Taiwanese adults. The study shows that the subjects widely lack knowledge in the cognition of physical fitness and exercise prescription. Furthermore, a self-pay service for the physical fitness assessment and individualized exercise prescription were acceptable to most subjects, especially those undergoing regular health examinations. The findings are encouraging and will aid support for health organizations and professionals in the development and management of promotion strategies on health-related physical fitness in preventive medicine and health promotion.

Project description:ObjectiveTo assess the physical activity levels of pregnant women and to examine the characteristics associated with the practice of exercise and the activities of daily living during pregnancy.MethodsFor this cross-sectional study, 1,279 women were recruited within 72 hours postpartum. They were interviewed about their socio-demographic data and obstetric history and were administered self-report questionnaires about exercise and daily physical activities during pregnancy. Data on the current pregnancy, labor, delivery, and newborn outcomes were collected from participants' medical records. To analyze factors related to the practice of exercise, we used the student t-test, X², and odds ratio (OR), with a corresponding 95% confident interval (CI), followed by a multiple logistic regression. The significance level was 5%.ResultsCompared to the pre-pregnancy period, the prevalence of physical activity among participants was lower throughout pregnancy (20.1%) (p = 0.01). Half of the women interrupted practicing physical exercise due to pregnancy. The lowest prevalence of exercise was observed in the first (13.6%) and third trimesters (13.4%). Less than half of women received exercise guidance during prenatal care meetings (47.4%). Walking was the most commonly reported exercise, followed by water aerobics. Factors positively associated with exercise practice were higher educational level (OR= 1.82; CI 95% 1.28-2.60), primiparity (OR=1.49; CI 95% 1.07-2.07), exercising before pregnancy (OR= 6.45; CI 95% 4.64-8.96), and exercise guidance during prenatal care (OR=2.54; CI 95% 1.80-3.57). Mildly intense exercise and domestic activities were most frequently reported among pregnant women. There were no differences in maternal and perinatal outcomes between active and sedentary pregnant women.ConclusionThe findings indicate that promoting physical activity remains a priority in public health policy, and women of childbearing age, especially those planning a pregnancy, should be encouraged to adopt an exercise routine or maintain an active lifestyle during pregnancy in order to avoid sedentary- and obesity-associated risks.

Project description:ObjectiveThe purpose of this study was to determine the relationships between noncognitive traits (grit, resilience, and mindset-type), academic success, and clinical performance in physical therapist students.MethodsThis cross-sectional study using self-administered surveys was undertaken with final-year physical therapist students enrolled in 4 Australian universities. Participants completed validated questionnaires measuring grit, resilience, and mindset type. Academic transcripts were obtained to quantify academic success and clinical performance. A multiple regression analysis explored predictors of academic success and clinical performance in relation to sociodemographic factors, grit, resilience, and mindset type.ResultsA total of 266 students participated in the study (80% recruitment rate). Overall, 25% of students had low resilience, 20% had low grit, and 14% had a fixed mindset type. Grittiness was positively associated with academic success (r = 0.24) and clinical performance (r = 0.22) and negatively associated with failing a clinical placement (r = -0.20). Grit was an independent predictor of overall academic success (β = 0.24, P ≤ .01) and clinical performance (β = 0.15). Students with low grit were twice as likely to fail a clinical placement compared with students with moderate or high grit (risk ratio = 2.03, 95% CI = 1.06 to 3.89).ConclusionGrit was an independent predictor for overall academic success and clinical performance in final-year physical therapist students. Low grit may impact negatively on learning and students' ability to cope with challenges associated with university studies and clinical education. Further studies should investigate interventions that best develop grit in health professional students and the overlapping nature of grit, resilience, and a growth mindset.ImpactThis study helps universities and educators understand noncognitive factors predicting academic success and clinical performance in physical therapist students. Universities and clinical educators may consider screening and providing proactive strategies for students with low grit to improve success and general wellbeing.
