Correlating Physical Activity (PA) with Physiological Health in College Students

To examine self-reported physical activity levels from the International Physical Activity Questionnaire (IPAQ) as an independent predictor of dual-energy x-ray absorptiometry (DXA)-measured percent body fat (%BF) from body mass index (BMI), gender, and race. Two hundred and seventy-eight students, aged 18-24 yr, volunteered to participate. There were 133 males (85 white and 48 black) and 145 females (77 white and 68 black). Total activity levels were quantified in MET hours per week (MET h wk(-1)) using the IPAQ short form. Height and weight were measured, and BMI values were calculated (kg m(-2)). %BF was assessed using DXA. Linear regression analysis was used to develop and compare a body fat prediction equation with (full) and without (reduced) the variable MET-h.wk. Both models included BMI, gender, and race as predictor variables. The prediction sum of squares (PRESS) statistic was used to cross-validate both models, and the individual predictive accuracy was compared using modified Bland-Altman plots. Mean +/- SD values were as follows: BMI = 24.4 +/- 4.1 kg m(-2), %BF = 24.5 +/- 9.3%, and MET h wk(-1) = 37.4 +/- 21.9. Gender, BMI, and race explained 81% of the variance in %BF, with a root mean square error (RMSE) of 4.07. The full model with MET-h.wk improved the prediction of %BF by 2% (R2 = 0.83, RMSE = 3.87). When cross-validated, the corresponding PRESS statistics for the reduced and full model were 4.10 and 3.90, respectively. Bland-Altman limits of agreement were greater for the reduced model compared with the full model (-8.09, 8.10 vs -7.67, 7.68). These results suggest that %BF can be predicted with greater precision and accuracy in a young adult population when MET-h.wk are included in addition to BMI, gender, and race.

Aging, in conjunction with decreasing physical activity, is associated with a range of health problems. Simple, low-maintenance, population-based means of promoting activity to counteract the age-associated decline are required. We therefore assessed the effect of pedometry and buddy support to increase physical activity. We undertook a clustered randomized trial (HKCTR-346) of 24 community centers involving 399 older Chinese participants (≥ 60 yr). Centers were randomly allocated to 1) pedometry and buddy, 2) pedometry and no buddy, 3) no pedometry and buddy, and 4) no pedometry and no buddy with a 2 × 2 factorial design. The trial simultaneously tested the individual and combined effects of the interventions. The intervention groups also received monthly organized group activities to provide encouragement and support. Outcome measures were assessed at 6 and 12 months, including physical fitness and activity and cardiovascular disease risk factors (anthropometry and blood pressure). From the 24 centers, 356 volunteers (89.2%) completed the study. Those receiving the interventions had higher mean physical activity levels at 12 months of 1820 (95% confidence interval (CI) = 1360-2290) and 1260 (95% CI = 780-1740) MET·min·wk(-1), respectively relative to the decrease in the control groups. The buddy peer support intervention significantly improved mean aerobic fitness (12% [95% CI = 4%-21%]) and reduced both body fat (-0.6% [95% CI = -1.1% to 0.0%]) and time to complete the 2.5-m get-up-and-go test (-0.27 [95% CI = -0.53 to -0.01] s). No other improvements in the cardiovascular disease risk factors were observed. The combination of motivational tools was no better than the individual interventions. Both motivational interventions increased physical activity levels, and the buddy style improved fitness. These tools could be useful adjuncts in the prevention of obesity and age-related complications.

To investigate the association between diabetes symptoms and physical activity (PA) levels among middle-aged and older Chinese adults. Data for this study were obtained from 2018 Charles data. Z test, logistic regression analysis, and linear hierarchical regression analysis were performed in 5352 individuals aged ≥50 years with complete information. In terms of diabetes, 6.8% of the middle-aged and elderly people with diabetes were detected, and 93.2% of the middle-aged and elderly people without diabetes symptoms. The proportion of middle-aged and elderly people with high PA levels was 50.5%, and the proportion of middle-aged and elderly people with low PA was 49.5%. There was a significant positive correlation between low PA and diabetes (P < .05). After adjusting demographic characteristics (gender, registered permanent residence type, education level, age, widowhood) and health status characteristics (poor mood, asthma, hyperlipidemia, disability, memory disease, self-assessment of health status, hypertension, smoking, stroke, depression), there was still a statistical significance between PA level and diabetes (P < .05). The risk of diabetes of middle-aged and elderly people in China increases with age, while the risk of diabetes of middle-aged and elderly people with low level of PA is higher. The risk of diabetes is high among middle-aged and elderly people who are old, have poor self-evaluation health, suffer from hyperlipidemia, memory disease, and asthma. The middle-aged and old people should increase their PA levels to prevent and improve diabetes.

The aim of the current study is to analyze the longitudinal effects of certain biopsychosocial variables (socioeconomic status, Body Mass Index (BMI), body image and well-being (QL)), measured at three different menarche stages (S1: before menarche, S2: soon after menarche, and S3: one year after S2), on physical activity and inactivity levels in early adolescence. The sample comprised 136 Brazilian teenagers (10-13 years old), showing BMI 18.98 kg/m2 at the initial assessment, who voluntarily participated in the study. Data concerning the following variables were collected in 2010 (S1), 2011 (S2) and 2012 (S3): family income (FI) (socioeconomic anamnesis), BMI (body mass and height), well-being (Autoquestionnaire Qualité de Vie Enfant Imagé) and body image (Body Shape Questionnaire). The physical activity and inactivity levels were measured in S3, only, through the International Physical Activity Questionnaire. The Pearson's correlation and the longitudinal path analysis technique were used to statistically analyze the data. The main results indicated that only family income and BMI, measured soon after menarche (S2), showed significant effect on physical activity and inactivity levels. More specifically, family income has positively influenced (β=0.25) physical inactivity levels and negatively influenced (β=-0.14) moderate physical activity levels, whereas BMI has positively influenced (β=0.15) walking levels and negatively influenced (β=-0.13) vigorous physical activity levels. These results suggest that the body image and well-being perceived by the teenagers at different menarche stages are not determining factors of their physical activity levels in early adolescence. On the other hand, the effects of socioeconomic status and BMI on early adolescent girls' physical activity and inactivity levels depend on the assessment period.

Physical activity (PA) has a positive effect on preventing risk on cardiovascular and metabolic syndrome, including obesity. Learning behavior that tends to be sedentary causes medical students to tend to be physically inactive. This present study aimed to associate the physical activity (PA) level with blood pressure, body mass index, and non-fasting blood glucose level (NFBG) among medical students. This cross-sectional study was conducted from February to March in 2019 on the first-year medical students at Sultan Agung Islamic University (UNISSULA). A total of 167 medical students (64.7% female and 35.3% male) were enrolled in this study. The international physical activity questionnaire (IPAQ)-short form was used to measure the PA level. The activity level was classified into low, moderate, and high. Blood pressure and glucose level were measured using a digital sphygmomanometer and NFBG dipstick. The association between PA level and Body Mass Index (BMI), Blood Pressure (BP), and NFBG level were analyzed using Spearman's correlation test. Chi square test was done to analyse the difference of PA level between male and female groups. The majority of the respondents had a low PA level (64.7%). A positive association was shown between PA level and BMI (p&lt;0.05, r=0.192). Female medical students tend to be physically inactive than males (OR 2.004, 95% CI (1.038-3.8690)). Female students need to be encouraged to do more physical activity. The university's policies that promote physical outdoor activity need to be suggested. Â

BackgroundOverweight and obesity are growing health problems both worldwide and in Malaysia due to such lifestyle changes as decreased physical activity (PA), increased sedentary behavior and unhealthy eating habits. This study examined the levels and patterns of PA among normal-weight and overweight/obese adults and to investigate the association between PA level and overweight/obesity in Malaysian adults.MethodsThis study used data from the 2015 National Health and Morbidity Survey (NHMS), a nationwide cross-sectional survey that implemented a two-stage stratified random sampling design. Respondents aged 18 years and above (n = 17,261) were included in the analysis. The short version of International Physical Activity Questionnaire (IPAQ) was administered to assess the respondents’ PA levels. The respondents’ height and weight were objectively measured and body mass index (BMI) was calculated. The respondents were categorized according to BMI as either normal-weight (18.5–24.9 kg/m2) or overweight/obese (≥ 25 kg/m2). Descriptive and complex sample logistic regression analyses were employed as appropriate.ResultsOverall, approximately 1 in 2 respondents (51.2%) were overweight/obese, even though the majority (69.0%) reporting at least a moderate level of PA (total PA ≥ 10 MET-hours/week). In both normal-weight and overweight/obese groups, a significantly higher prevalence of high PA (total PA ≥ 50 MET-hours/week) was observed among men than women (p < 0.001), but women reported a significantly higher prevalence of low and moderate PA than men (p < 0.001). Men reported significantly higher activity levels (in MET-hours/week) than women with regard to walking, vigorous-intensity PA and total PA (p < 0.001). Overweight/obese men reported a significantly lower level of vigorous-intensity PA and total PA than normal-weight men (p < 0.001). A low level of PA was associated with the risk of overweight/obesity (Adjusted OR = 1.14; 95% CI: 1.01–1.30) compared to a high level of PA among men but not among women.ConclusionsThe levels of PA were inversely related to the risk of overweight/obesity in men but not in women. Programs designed to reduce overweight/obesity rates should encourage the practice of moderate- to vigorous-intensity PA. Future research should consider using longitudinal and prospective approaches that simultaneously measure dietary intake, PA and BMI among Malaysian adults to investigate the actual relationship between PA and overweight/obesity.

SAT0618-HPR PATIENTS WITH INFLAMMATORY MYOPATHIES WHO DO NOT REACH HEALTH ENHANCING LEVELS OF PHYSICAL ACTIVITY REPORT HIGHER LEVELS OF ANXIETY AND DEPRESSION - A CROSS-SECTIONAL STUDY OF SELF-REPORTED DATA

The aim of this study is to determine how anthropometric variables (body weight, body height, upper and lower limb length), Body Mass Index (BMI) and physical activity (PA) levels affect the number of cycles completed in 3-Minute Burpee Test (3-MBT) among male and female teenagers of University Practice Senior High school. Thirty-two (32) males and 28 females aged 15-17 years engaged in low and moderate physical activity levels took part in the studies. International Physical Activity Questionnaire (IPAQ) short form was used to assess physical activity levels and 3-MBT was used to evaluate students’ endurance strength capacity. Participants’ limb lengths (for upper and lower) were measured and their BMI was calculated from their measured body height and weight according to standardized guidelines. The results were processed statistically using Pearson’s correlation, independent sample t-test and simple linear regression. In both sexes, only body mass and BMI were bound by negative significant correlation (p &lt; 0.05) with the number of cycles completed in the 3-MBT. Significant differences were noted between males and females engaging in 3-MBT (p &lt; .001). Physical activity levels in MET significantly predicted endurance strength scores (p &lt; .001) as assessed by 3-MBT. On the average, males completed 48.34 cycles/3 min and females scored 38.50 cycles/3 min. More cycles were completed by male and female students with moderate levels of physical activity compared to those characterized by low levels of PA. Males were characterized by higher anthropometric measurements excluding body mass index than females. Body mass, BMI and physical activity levels in MET were the only analyzed variables that significantly had influence on endurance strength (3-MBT) of both sexes.

SummaryObjectiveThere is diverse results on the association between physical activity and sleep. So this study investigated association of level and type of physical activity with short term insomnia among college students.MethodsA cross sectional study was conducted among college students in India. The sample was 662 students with 359 males and 303 females. The predictor variables were type and level of physical activity and predicted variables were sleep complaints.Physical activity components were aseesesed through international physical activity questionnaire and sleep complaints using Pitsburg sleep questionnaire. The binary logistic regression models were used for data analysis. Level of significance was set at p ≤ 0.05 for all the analysis.ResultsThe age (mean + SD) of the participants were 23.2 ± 3.5 years. The self reported symptoms of short trem insomnia such as global sleep quality (adjusted odds ratio(AOR) = 15.58), subjective sleep quality (AOR = 6.01), sleep latency (AOR = 5.09), sleep duration (AOR = 0.13), sleep disturbances (AOR = 4.88), day time sleep dysfunction (AOR = 5.59) had shown association with level of physical activity. There was no association of type of physical activity with any other predicted variables.ConclusionsThe findings of the present study supports that level of physical activity is a key predictor of short term insomnia symptoms among college students. There should be Interventions to maintain and improve the level of physical activity among students.

Association of Sitting Time and Physical Activity With CKD: A Cross-sectional Study in Family Practices

ABSTRACTObjectives:To synthesize the literature on Saudi college students physical activity (PA) levels, barriers, and facilitators, as well as the proportion of college students meeting WHO-recommended PA guidelinesMethods:A comprehensive search strategy was developed, and the databases PubMed, CINAHL, and Scopus were searched for relevant studies. The systematic review protocol was registered in PROSPERO and the PRISMA reporting guidelines were followed. Studies that enrolled Saudi college students and reported PA levels, barriers to PA, facilitators of PA, or adherence to WHO PA recommendations were included. Reviews, animal studies, and conference proceedings were excluded. The quality of the studies was assessed with a relevant study quality assessment tools and data were extracted and synthesized from all the included studies.Results:A total of 44 studies were included, with a combined sample of 29,580 students. Most of these studies used cross-sectional designs and self-reported PA levels using various scales, with the International Physical Activity Questionnaire being the most common one. The results show that a substantial proportion of students exhibited low PA levels, with only 27% meeting WHO-recommended PA cutoffs. The barriers to engaging in PA included lack of time, motivation, and facilities, while the facilitators comprised health benefits, social support, and weight management.Conclusion:Physical activity levels among Saudi university students are concerningly low, with many failing to meet the WHO-recommended PA cutoffs. Barriers such as time constraints and limited resources must be addressed through culturally tailored interventions, improved infrastructure, and awareness campaigns. Future scholars should conduct longitudinal studies and employ objective measures of PA to further inform public-health policy.PROSPERO Reg. No.: CRD42024542313
