INTRODUCTION: Extensive research has documented the beneficial effects of physical activity on health and fitness at youth and adults. The relationship between teachers and students health-conscious behavior and physical activity is an important factor to consider. Besides teacher student relationship and teachers’ role modelling, socio-economic status contributes to the development of sedentary lifestyles among the disadvantaged. While numerous studies have examined physical activity and fitness patterns among youth and adults, considerably fewer investigations have focused on teachers and there is limited research available comparing students’ and teachers’ health behaviors. The purpose of the study is to demonstrate the characteristics physical activity of high school and technical school students and teachers in a disadvantaged region. METHODS: State-maintained secondary and technical schools in the region were selected to participate in the study. A total of 834 individuals participated in the study, including 732 students (17.3±1.2 of age) and 102 teachers (48.2±11.4 of age). Data collection was conducted via a structured questionnaire that included socio-demographic questions, fitness self-assessment items, and the International Physical Activity Questionnaire-short form test. All data analyses were performed using IBM SPSS Statistics version 25.0 (p<0.05). RESULTS: During the week preceding the study, 24.1% of students and 28.0% of teachers reported no engagement in vigorous physical activity. On a scale of 1 to 4, the students subjective fitness was rated as close to good (2.81±0.85), while teachers rated students’ fitness level lower (2.06±0.71), and also, their own fitness was rated as good (2.84±0.79). Students’ metabolic equivalent values (ME=2732) was significantly higher than teachers’ (MET=2116). Students spent significantly more time walking and sitting (p<0.05) compared to teachers. Additionally, teachers employed at technical schools and students attending high schools exhibited significantly higher durations of sedentary behavior than their counterparts in high schools and technical schools, respectively (p<0.05). No significant correlations were found between students’ socio-economic situation and their physical activity levels. CONCLUSION: This study revealed that the activity levels in both students and teachers are insufficient to maintain optimal health in this disadvantaged region. Notably, there were a lot of differences between teachers and students. Teachers perceived the students’ physical activity levels to be lower than the students’ own assessments, while simultaneously rating their own fitness as higher, despite recording significantly lower metabolic equivalent values. These findings underscore the need for further research to elucidate the factors contributing to inadequate physical activity and to develop effective interventions tailored to both teachers and students.

INTRODUCTION: This study aimed to investigate: (1) the associations between physical activity (PA), blood lead (BL) and all-cause or cardiovascular disease (CVD) mortality risks, and (2) the combined effects of PA and BL on all-cause or CVD mortality risks. METHODS: A total of 22821 participants were included from the National Health and Nutrition Examination Survey (NHANES) database from 2007-2018. PA levels were assessed by Global Physical Activity Questionnaire (GPAQ). BL were measured using inductively coupled plasma mass spectrometry. Mortality status was obtained from the National Death Index (NDI) database. Statistical analyses were performed using the Cox proportional hazards models and restricted cubic spline (RCS). RESULTS: Compared with the sufficiently active PA group, the inactive PA group increased 88% all-cause mortality risk (HR = 1.88, 95% CI = 1.71 - 2.07) and 78% CVD mortality risk (HR = 1.78; 95% CI = 1.49 - 2.12). Compared with the minimal blood lead level (Min-BLL) group, the high blood lead level (H-BLL) groups increased 72% all-cause mortality risk (HR = 1.72, 95% CI = 1.41 - 2.10) , and 132% CVD mortality risk (HR = 2.32, 95% CI = 1.53 - 3.52). When compared with the Min-BLL group, H-BLL combined with inactive (HR = 2.45, 95% CI = 1.99 - 3.01) or insufficiently active PA group (HR = 1.69, 95% CI = 1.33 - 2.17) increased 145% or 69% all-cause mortality risk, and 200% (HR = 3.00, 95% CI = 1.95 - 4.62) or 135% (HR = 2.35, 95% CI = 1.44 - 3.84) CVD mortality risk. Compared with the sufficiently active PA group, inactive PA group combined with H-BLL (HR = 2.28, 95% CI = 2.04 - 2.25) or M-BLL (HR = 1.80, 95% CI = 1.57 - 2.07) increased 128% or 80% all-cause mortality risk, and 108% (HR = 2.08, 95% CI = 1.70 - 2.56) or 86% (HR = 1.86, 95% CI = 1.46 - 2.37) CVD mortality risk. RCS analyses showed BLL (ug/dL) above 0.12 (0.47), 0.83 (1.06), or 1.18 (1.18) in inactive, insufficiently active, or sufficiently active PA groups could increase all-cause (CVD) mortality risk. CONCLUSION: Physical inactivity or H-BLL can increase all-cause and CVD mortality risks. In addition, increasing PA can mitigate the adverse effects of H-BLL on mortality risk. For inactive or insufficiently active individuals, maintaining Min-BLL is essential to minimize the impact of lead exposure on mortality risks.

INTRODUCTION: Ramadan diurnal intermittent fasting (RDIF) is associated with a number of lifestyle modifications, including changes in sleep patterns, dietary habits, and physical activity (PA) [1]. An understanding of how RDIF affects PA behaviors is crucial for promoting cardiometabolic and mental health among individuals observing the fast. This systematic review and meta-analysis aimed to examine changes in resting metabolic rate (RMR) and PA levels before and during Ramadan, with a focus on PA levels, measurement instruments, and gender differences. Additionally, we explored whether changes in PA were associated with body weight changes during RDIF METHODS: This systematic review of observational studies was conducted following PRISMA guidelines. A comprehensive search of databases, including PubMed, Scopus, Medline, and Web of Science, was performed. Studies examining PA levels and RMR before and during Ramadan were included. Subgroup analyses were performed to examine differences in PA levels (sedentary behavior, light, moderate, vigorous), measurement instruments (objective and subjective), and by gender (male and female). Meta-regression was conducted to investigate the relationship between changes in PA and body weight outcomes. Random-effects meta-analyses were conducted using R programming software RESULTS: revealed a significant reduction in objective PA during Ramadan compared to pre-Ramadan levels (SMD: -0.346, 95% CI: -0.575 to -0.117, p = 0.003), with high heterogeneity (I² = 83.84%). Sedentary behavior also increased significantly during RDIF (SMD: -0.261, 95% CI: -0.441 to -0.082, p = 0.004). Subgroup analyses indicated that vigorous PA (VPA) showed a significant decline (SMD: -0.445, 95% CI: -0.863 to -0.027, p = 0.036), while light PA (LPA) also decreased significantly (SMD: -0.263, 95% CI: -0.36 to -0.166, p < 0.0001). No significant changes were observed in moderate PA (MPA) (SMD: -0.022, 95% CI: -0.610 to 0.940, p = 0.94). Gender-specific analyses revealed no significant differences in PA changes between males and females (p > 0.05). Resting metabolic rate (RMR) showed a non-significant decrease during Ramadan (WMD: -38.97 kcal/day, 95% CI: -128.34 to 50.38, p = 0.392). Meta-regression analysis indicated that changes in PA were not significantly associated with changes in body weight post-RDIF (p > 0.05) CONCLUSION: Vigorous and light-intensity activities decline significantly during Ramadan, accompanied by increased sedentary behavior. Objective measures of PA captured more pronounced reductions compared to subjective instruments. The overall decline in PA highlights the need for targeted interventions to promote active lifestyles during RDIF. These findings emphasize the importance of maintaining PA to support health outcomes during periods of fasting References: 1- Aljaloud, K. S. (2024).
