    Background

    Polycystic ovary syndrome (PCOS) is a common endocrine disorder that has become an increasing concern for adolescents globally.

    Objectives

    This study aimed to compare nutritional patterns, including macronutrient intake and levels of physical activity, among adolescents with and without PCOS.

    Methods

    This cross-sectional study involved 238 adolescents with and without PCOS, conducted between February 2021 and October 2021 in Gorgan, Iran, using a simple random sampling method. The standard Nutrition Questionnaire and the validated Physical Activity Questionnaire (AFPAQ) were the two main tools for data collection. To compare macronutrient intake and physical activity levels, statistical analyses included descriptive statistics, the Student's t -test, chi-square, and the Mann-Whitney U test.

    Results

    The age, education level, and family history of PCOS did not significantly differ between the two groups. However, Body Mass Index (BMI), age at menarche, and menstrual interval and duration were significantly different (P < 0.05). Adolescents with PCOS had a higher BMI (P < 0.001), experienced menarche at a later age (P < 0.09), and had longer intervals between menstrual cycles, showing prolonged amenorrhea (P < 0.001). Affected adolescents had higher intakes of calories, carbohydrates, and fats, while protein consumption and physical activity levels were significantly lower (P < 0.001).

    Conclusions

    Adolescents with PCOS exhibited higher intakes of calories, carbohydrates, and fats, while their protein consumption and physical activity levels were lower compared to those without the syndrome. Educating adolescents about these dietary and activity levels may be effective in preventing the occurrence of PCOS.

    This study aims to assess the anthropometric and health characteristics of foreign students at the Science and Research Branch of Islamic Azad University in Tehran, Iran, during the 2023-2024 period. A total of 400 non-Iranian students participated in this cross-sectional study. Anthropometric measurements, including weight, height, BMI, waist circumference, and body composition, were taken using standardized equipment. Physical activity levels, blood pressure, fasting blood sugar, and heart rate were also assessed. The results revealed a significant prevalence of overweight and obesity (21.75%), particularly among females (31.93%), and high rates of hypertension and prediabetes. The study found a high proportion of sedentary individuals (70.6%), which is a key contributor to the observed health risks. These findings highlight the importance of addressing obesity-related health issues, particularly in the context of non-communicable diseases (NCDs), and their economic impact. This data is crucial for the development of targeted health policies, such as medical tourism and insurance adjustments for individuals at higher health risks. The study concludes that proactive measures are essential to prevent and manage the health conditions prevalent in this population.

    Background

    Adherence to treatment and regular physical activity in individuals with asthma will culminate in favorable clinical outcomes, including an effective disease management and an improved quality of life.

    Objectives

    The present study aimed to determine the physical activity level and association with adherence to treatment and quality of life in individuals with asthma.

    Methods

    This cross-sectional study was conducted on 505 individuals referring to the respiratory ward of Vali-e-Asr Hospital in Zanjan, Iran. Participants were selected using a convenience sampling method. Data were collected using the socio-demographic information form, the International Physical Activity Questionnaires (IPAQ), Modanloo Adherence to Treatment Questionnaire (MATQ), and the St. George's Respiratory Questionnaire (SGRQ). Data analysis was performed using descriptive statistics and the Kruskal-Wallis test in SPSS software version 16.

    Results

    The majority of participants were male (57.2%) with a mean (standard deviation [SD]) age of 66.35 (15.33) years. The physical activity level of the majority of participants was vigorous (43.4%). The mean (SD) total scores for adherence to treatment and quality of life were 120.83 (8.92) and 35.42 (5.02), respectively. According to the findings, physical activity had no statistically significant association with adherence to treatment (p=0.535) and quality of life (p=0.173).

    Conclusion

    In the present study, physical activity level was vigorous in asthmatic participants. Adherence to treatment among participants was at a good level, and quality of life was at a moderate level. Therefore, the design of supportive educational interventions is recommended to improve quality of life and promote lifestyle modification in individuals with asthma.

    Prostate cancer affects the majority of older men and can be used preventively. Prostate cancer treatment and the resulting system complications are a considerable health burden. Many factors have been identified to prevent prostate cancer; among them, physical activity may play an important role in the prevention of this type of cancer. It was shown that exercise has an anti-risk, antioxidant, and regulatory mechanism for cancer and its complications. In addition, several studies have demonstrated that physical activity prevents disease recurrence and improves survival after diagnosis and treatment of prostate cancer. Physical activity is a crucial factor in the prevention of prostate cancer and can improve outcomes for patients diagnosed with the disease. Public health policies should promote regular exercise as an effective strategy for prostate cancer prevention and management.

    Background
    Obesity has become a common health problem, and its prevalence has been increasing worldwide. The present study aimed to determine whether factors such as sleep quality, mental health status, and eating patterns are different between normal-weight and overweight/obese students in Shiraz University of Medical Sciences, Shiraz, Iran.
    Methods
    In a case-control study, 33 overweight/obese and 101 normalweight students were enrolld that served as case and control groups, respectively. Anthropometric measurements, eating patterns, sleep quality, and psychological mood disorders were evaluated and compared to the control group.
    Results
    There were no significant differences between groups regarding sleep quality scores. Although students with a body mass index (BMI)>25 showed higher depression, anxiety, and stress scores, but these differences were not statistically significant between the groups. There was no significant difference in relation to physical activity between the two groups. Besides, dietary habits were almost similar in both groups, and there was no significant difference between normal-weight and overweight/obese females regarding dietary habits and meal patterns.
    Conclusion
    There was no significant difference in sleep quality, depression, anxiety, and stress scores among normal-weight and overweight female students. Moreover, physical activity level and dietary habits, including meal patterns, were comparably similar between the two groups. This indicates a lack of correlation between weight status and the psychological and behavioral variables examined in this population.

    زمینه و هدف

    دردهای مزمن میگرن می توانند باعث مشکلات جسمی، روانی و اجتماعی در مبتلایان به میگرن شوند. با توجه به شیوع بالا و اثرات منفی میگرن، این مطالعه با هدف تعیین ارتباط بین مهارت های خودمدیریتی درد با شدت سردرد و فعالیت جسمانی بیماران میگرنی در مراکز درمانی دانشگاه علوم پزشکی گلستان در سال 1402 انجام شده است.

    روش ها

    این مطالعه یک پژوهش مقطعی از نوع توصیفی-همبستگی است. نمونه پژوهش شامل 200 نفر مبتلا به میگرن بود که بر اساس معیارهای ورود انتخاب شدند. برای جمع آوری داده ها از پرسشنامه اطلاعات دموگرافیک، پرسشنامه سردرد میگرن (PTMHQ)، پرسشنامه بین المللی فعالیت بدنی (IPAQ) و مقیاس خودمدیریتی استفاده شد. پرسشنامه ها در اتاقی آرام در درمانگاه های اعصاب به روش مصاحبه توسط پژوهشگر تکمیل شدند. اطلاعات جمع آوری شده با استفاده از آمار توصیفی و استنباطی با نسخه 16 نرم افزار آماری SPSS تحلیل شدند. سطح معنی داری (0/05>P) بود.

    نتایج

    نتایج نشان داد که خودمدیریتی درد با شدت سردرد همبستگی معنی دار آماری معکوس دارد. به عبارتی با افزایش خودمدیریتی، شدت سردرد کاهش می یابد؛ هرچند این همبستگی در سطح ضعیف بود (0/176-,r=0/013p=). خودمدیریتی با فعالیت جسمانی همبستگی معنی دار آماری مستقیم داشته است به عبارتی با افزایش خودمدیریتی، فعالیت بدنی نیز افزایش می یابد (0/004p= ،0/205=r).

    نتیجه گیری

    خودمدیریتی درد به طور معناداری شدت سردرد و طول مدت حملات میگرن را کاهش داد. همچنین، خودمدیریتی درد با افزایش فعالیت های بدنی و کاهش زمان نشستن مرتبط است. این یافته ها بر اهمیت استراتژی های خودمدیریتی در مدیریت میگرن و بهبود کیفیت زندگی بیماران تاکید دارد.

    Background & Aim

     

    Chronic migraine pain can cause physical, psychological, and social problems for those who suffer from migraines. Due to the high prevalence and negative impact of migraines, this study aims to investigate the correlation between pain self-management skills, headache intensity , and physical activity among migraine patients at the Golestan University of Medical Sciences healthcare centers in 2023.

    Methods

    This descriptive-correlational study was done on 200 migraine sufferers based on specific inclusion criteria. Data were collected using the Migraine Headache Questionnaire (PTMHQ), the International Physical Activity Questionnaire (IPAQ), and the Self-Management Scale. The questionnaires were completed in a quiet room within the neurology clinics to provide suitable conditions for the patients. The collected data were analyzed using descriptive and inferential statistics in SPSS software, version 16. The significance level was set at 0.05.

    Results

    The results indicated that self-management was significantly associated with a decrease in headache severity. In other words, as self-management increased, headache intensity decreased. However, the correlation between self-management and headache severity was low (p =0.013, r = -0.176). Self-management showed a statistically significant positive correlation with physical activity, indicating that as self-management increased, so did physical activity (p = 0.004, r = 0.205).

    Conclusion

    The results of this study demonstrate that pain self-management is highly effective in reducing the intensity and the duration of headaches and migraine attacks. Additionally, it has been found to be associated with increased physical activity and decreased sedentary behavior. These findings highlight the crucial role of self-management strategies in effectively managing migraine and enhancing the overall quality of life for patients.

    Background

    Students making the transition from high school to university find it difficult to maintain good eating routines/lifestyles and mental health, due to time constraints and stress. The goal of the study was to analyse the correlation between previously mentioned topics.

    Methods

    We included 948 students, aged 18-27, at the Faculty of Medical Sciences in Serbia and the research was conducted in 2020. Chi-square was used for statistical analysis. Modified WHO questionnaire for lifestyle and eating habits was used, as well as standardized questionnaires for anxiety and depression.

    Results

    Respondents who had more prominent symptoms of depression (moderate or severe) and anxiety had a significantly higher percentage of eating less than three meals a day (47.7%, 35.7%), skipped breakfast (38.6%, 33.5%), consumed alcohol (11.4%, 3.8%), used energy drinks (38.6%, 31.7%), were on some type of diet (36.6%, 30.2%), were not satisfied with their appearance (66.7%, 53%) and not engaging in physical activity (43.2%, 33.1%). Significant predictors for severe depressive and anxiety symptoms were the consumption of alcoholic beverages, energy drinks, satisfaction with personal appearance and physical activity during a day.

    Conclusion

    The results suggest that some of the eating and lifestyle habits were linked to higher risks of developing depressive or anxiety symptoms.

    Purpose

    One of the biggest factors reportedly interfering with the lives of individuals who suffer from multiple sclerosis (MS) is fatigue. Prior research has demonstrated that combined training may benefit patients with MS. However, it has not been studied how combined exercise can lessen fatigue in people with MS. This systematic review and meta-analysis summarizes the results of studies that examine the effects of combined training on fatigue in individuals with MS.

    Methods

    We investigated randomized controlled studies (RCTs) that examined how combination training affected fatigue and were published from the start of the research until May 2024. The Wiley online library, PubMed, Medline, PEDro, ScienceDirect, and Frontiers were among the electronic databases that were searched. PEDro and McMaster’s measures were used to assess the quality of included research. 

    Results

    The study’s requirements were satisfied by six RCTs with 279 participants. Using a random effect model of meta-analysis, the weighted mean differences of fatigue were 1.81 (95% CI, 2.83%, 0.79%) with P=0.002. Accordingly, exercise training is useful in lowering fatigue in individuals with MS since all included RCTs revealed significant differences between the subjects assigned to the combined exercise group and the control group. 

    Conclusion

    Combined training can be a useful strategy for helping individuals with MS manage their weariness.

    Background
    The outbreak of COVID-19 has been associated with various physical and psychological effects. The role of exercise in strengthening the immune system and reducing inflammation has already been proven. Moderate levels of exercise can enhance overall immunity. Exercise can improve intracellular metabolism and increase cell defense activity by improving inflammatory cytokines, immature B cells, and cytotoxic T cells. Therefore, exercise is known as a defense strategy against respiratory infections. Here the role of exercise in improving respiratory function and physical activity in hospitalized patients with COVID-19 was evaluated.
    Methods
    The present study was performed as a randomized clinical trial on 90 hospitalized patients with COVID-19. Both groups received all routine treatments (medication, invasive or non-invasive ventilation, physiotherapy). Then, in the experimental group, standard exercises were provided to improve the patients’ physical condition and exercise capacity. After two weeks and one month later, all indices were measured again in two groups.
    Results
    The results of the present study showed that exercise causes significant changes in indicators such as 6-Minute Walk Test (6MWT) (p=0.001), balance score (p=0.02), and Sf1 score (p=0.05) in two time periods before and after rehabilitation in two groups.
    Conclusion
    Performing standard and defined exercise exercises for patients with the new coronavirus improves the physical activity and respiratory function of patients.

    Background

    Children with intellectual impairment have impaired or delayed development of motor skills due to impaired mental function. In the present study, the effect and durability of exercise and sports games on the motor abilities and quality of life (QoL) of children with intellectual impairment were investigated.

    Methods

    This randomized controlled study assessed sixty boys aged 8-12 years with mild intellectual impairment in three groups: an exercise group (aerobic and resistance training), a sports games group (basketball and futsal), and a control group, for 8 weeks. Motor abilities were assessed using the 4x9 m shuttle run, ball-catching against a wall, stork balance test, and the Timed Up and Go (TUG) test, while BMI and QoL were evaluated using the Pediatric Quality of Life Questionnaire (PedsQL-parent proxy report) questionnaire. Data were analyzed using SPSS, with significance set at P < 0.05.

    Results

    Significant differences were observed between the experimental and control groups in post-test results for motor ability and QoL (P < 0.05). During follow-up, static balance (P = 0.001) and QoL (P < 0.05) also showed significant improvements in the experimental groups compared to the control group. Moreover, coordination improved significantly in the sports games group compared to the control group (P = 0.016), while agility improved in the exercise group (P = 0.006). Follow-up analysis revealed significant differences in overall QoL, psychosocial health, and school functioning between the exercise and sports games groups (P = 0.001). Intra-group analysis showed significant differences in motor abilities (except for BMI) and QoL in both experimental groups and at all-time points (P = 0.001).

    Conclusion

    The interventions demonstrated positive effects on most variables of motor ability and QoL. The exercise group showed superior improvements in motor abilities, while the sports games group exhibited greater enhancements in QoL. Integrating both types of interventions may yield more comprehensive benefits.

    Background

     While the direct benefits of food assistance programs are well-documented, there is a need to explore indirect benefits like increased physical activity. This study examined whether participation in the Supplemental Nutrition Assistance Program (SNAP) was associated with improved physical activity levels in children and adolescents aged 2-17 in the United States during 2017-2018.

    Study Design:

     A cross-sectional study.

    Methods

     This cross-sectional study used a subset of National Health and Nutrition Examination Survey (NHANES) data (n=2620). In the NHANES 2017-2018 dataset, physical activity was measured through self-report questionnaires, which captured participants’ frequency, duration, and intensity of various activities. We used weighted logistic regression and the Hosmer - Lemeshow - Sturdivant forward model - building strategy to investigate this hypothesized association using SAS version 9.4.

    Results

     In the adjusted model, controlling for the other variables in the model, we found that children and adolescents from households that had received SNAP/Food Stamps had 1.53 times higher odds (odds ratio [OR]=1.53, 95% CI: 1.24-1.89) of achieving the recommended guidelines of 60 minutes of daily physical activity compared to those who had not received benefits. Each additional year of age resulted in 0.82 times lower odds (OR=0.82; 95% CI: 0.79, 0.85) of meeting the recommended amounts of physical activity. Additionally, each unit increase in BMI was associated with 0.96 times lower odds (OR=0.96, 95% CI: 0.93, 0.98) of engaging in recommended physical activity.

    Conclusion

     These findings suggest that participation in the SNAP/Food Stamps program may indirectly benefit participants by increasing physical activity levels.

    Background

    Adequate physical activity is essential to healthy aging. This study aimed to examine the construct validity of the Persian version of the Physical Activity Scale for the Elderly (PASE) among community-dwelling adults, which would be used as a screening tool at the Neyshabur longitudinal study on the aging (NELSA) Center.

    Methods

    This cross-sectional study was conducted in Neyshabur, Iran, as a pilot phase at the NELSA center between May and January 2019. The sampling method was a stratified random method. For explanatory factor analysis (EFA) and confirmatory factor analysis (CFA), 300 and 650 community-dwelling adults aged 50 and older were selected, respectively. EFA was used with the principal component extraction method, and Varimax rotation and CFA were performed with the maximum likelihood estimation method.

    Results

    Of the 950 participants, 445 (46.8%) were male, and 505 (53.2%) were female. The mean age of participants was 63 ± 8.6 years. The mean physical activity score was 89.7 ± 70.7. According to the percentage of variance explained in EFA, all five extracted factors explained 62.7% of the total variance. The results of CFA showed that all item-scale relationships were significant (P < 0.05), except for household activity (Q8) and leisure time activity (Q2) (P > 0.05). The values of the fit indices showed that the model fits well with the data.

    Conclusion

    The EFA and CFA confirmed the construct validity of the Persian version of PASE. This questionnaire is suitable for measuring the physical activity level of older Persian adults.

    Physical activity is recognized as a key lifestyle modification for the prevention and management of hypertension. Regular exercise can lower blood pressure, improve cardiovascular health, and reduce hypertension-related complications. Moderate-intensity aerobic exercise for at least 150 minutes per week or vigorous-intensity exercise for 75 minutes per week is recommended. Resistance training should be performed at least twice weekly, targeting major muscle groups.

    Conclusion

    Incorporating physical activity into daily routines should be encouraged as an influential non-pharmacological approach for people with hypertension or those at risk of developing it. Further research is necessary to investigate optimal exercise protocols and long-term adherence strategies for sustainable blood pressure control.

    Objective

    This study aimed to examine the effect of physical activity at varying intensities on anxiety, blood pressure, and blood glucose levels in primiparous women aged 20-30 years.

    Materials and Methods

    The study population comprised 200 primiparous pregnant women. Data were collected using the Spielberger Anxiety Questionnaire and a physical activity questionnaire. Pearson's correlation test was employed to analyze the relationships between physical activity, blood pressure, blood glucose, and anxiety levels. Analysis of covariance (ANCOVA) was used to evaluate the effects of different physical activity intensities on these variables, with statistical significance set at P< 0.05.

    Results

    The Pearson correlation test revealed a significant inverse relationship between physical activity and blood glucose (P= 0.011, r= -0.55) as well as between physical activity and blood pressure (P= 0.003, r= -0.62) in primiparous women. Similarly, an inverse and significant relationship was observed between physical activity and anxiety levels (P= 0.021, r= -0.47 for state anxiety; P= 0.001, r= -0.78 for trait anxiety). The ANCOVA results demonstrated significant differences in blood pressure and blood glucose levels among pregnant women across three levels of physical activity intensity (P= 0.001 for both).

    Conclusion

    The findings suggest that increased physical activity is associated with reductions in blood glucose levels, blood pressure, and anxiety in pregnant women. These results highlight the potential benefits of regular physical activity for managing these health indicators during pregnancy.

    زمینه و هدف

    اختلالات قاعدگی یکی از مهم ترین علل ناباروری محسوب می شوند. اطلاعات دقیقی در خصوص رابطه استرس روانی و سطوح کورتیزول و فعالیت بدنی با اختلالات قاعدگی وجود ندارد. هدف مطالعه حاضر مقایسه اختلالات قاعدگی و ارتباط آن با استرس، کورتیزول و سطح فعالیت بدنی در دختران ورزشکار و غیر ورزشکار بود.

    روش تحقیق: 

    در این مطالعه مورد-شاهدی تعداد 60 دختر جوان 18 تا 25 ساله حداقل با دو اختلال قاعدگی در دو گروه ورزشکار (VO2max> 40، 30 نفر) و غیر ورزشکار (30 نفر) با ارزیابی انواع اختلالات قاعدگی، پرسشنامه سطح فعالیت بدنی بک، پرسشنامه استرس درک شده کوهن و سطح کورتیزول بزاق مقایسه شدند.

    یافته ها

    شیوع اختلالات قاعدگی بین دو گروه تفاوت معنی داری نداشت (05/0P). سطح فعالیت بدنی بالا در دختران غیر ورزشکار همراه با کاهش بروز اختلال دیسمنوره و کاهش استرس و کورتیزول بود (05/0>P). در دختران ورزشکار مدت زمان بالای فعالیت طی یک روز و فرکانس بالای تمرینات به ترتیب همراه با افزایش خطر بروز آمنوره و کاهش خطر بروز متروراژی بود، از طرفی سابقه فعالیت ورزشی رابطه منفی معنی داری با سطح استرس و کورتیزول داشت (05/0>P).

    نتیجه گیری

    سطح فعالیت بدنی بالا در دختران غیرورزشکار و سابقه ورزشی بالا در دختران ورزشکار می تواند در کاهش کورتیزول و استرس و در نتیجه کاهش رخداد برخی اختلالات قاعدگی موثر باشد. در دختران ورزشکار مدت بالای تمرینات ورزشی طی یک روز بهتر است جهت پیشگیری از رخداد برخی اختلالات قاعدگی توسط مربیان و ورزشکاران مورد توجه قرار گیرد.

    Background and Aims

    Menstrual disorders contribute significantly to infertility. The relationship between psychological stress, cortisol levels, physical activity, and these disorders remains unclear. The aim of this study was to compare menstrual disorders and their association with stress, cortisol, and physical activity in female athletes and non-athletes.

    Materials and Methods

    In this case-control study, a total of 60 young girls aged 18 to 25, each with at least two menstrual disorders, were evaluated in two groups: athletes (VO2max > 40, 30 participants) and non-athletes (30 participants). We assessed the type of menstrual disorder, level of physical activity, perception of stress using the Cohen scale, and salivary cortisol levels.

    Results

    There was no significant difference in the prevalence of menstrual disorders between the two groups (P<0.05). Dysmenorrhea and menorrhagia were common in both groups. However, hypomenorrhea and amenorrhea were more common in athletic girls with high cortisol levels, while oligomenorrhea was more common in non-athletic girls with high stress (P<0.05). In non-athletic girls, a higher level of physical activity correlated with a decrease in dysmenorrhea, stress, and cortisol levels (P<0.05). In female athletes, longer daily training and higher training frequency were associated with an increased risk of amenorrhea and a reduced risk of metrorrhagia, respectively. Conversely, there was a significant negative correlation between a history of exercise and stress and cortisol levels (P<0.05).

    Conclusion

    A high level of physical activity in non-athletic girls and a long history of sports in athletic girls may be effective in reducing cortisol and stress and thus reducing the incidence of some menstrual disorders. For female athletes, prolonged daily exercise should be more considered by coaches and athletes to prevent the occurrence of some menstrual disorders.

    زمینه و هدف

    انجام فعالیت بدنی یکی از عامل های سلامت رفتاری است. مطالعه حاضر باهدف بررسی ارتباط بین میزان فعالیت بدنی با اختلال های رشدی کودکان و نوجوانان 7تا15 سال انجام شد.

    روش بررسی

    پژوهش حاضر از نوع توصیفی همبستگی بود. در این مطالعه 177 نفر از والدین کودکان 7تا15 سال شهر همدان شرکت کردند که به طور تصادفی ساده انتخاب شدند. داده ها به کمک پرسش نامه بین المللی سنجش میزان فعالیت بدنی (کراکر و همکاران، 1997) و پرسش نامه اختلالات رشدی 5تا15 سال نسخه والدین (کادسیو و همکاران، 2004) جمع آوری شد. تحلیل داده ها بااستفاده از آزمون همبستگی پیرسون در نرم افزار SPSS نسخه 26 صورت گرفت. سطح معناداری برای تمام آزمون ها کمتر از 0٫05 در نظر گرفته شد.

    یافته ها

    نتایج نشان داد، بین فعالیت بدنی و اختلال در رشد مهارت های حرکتی، اختلال در ادراک، اختلال در زبان و ارتباط کلامی، اختلال در حافظه، اختلال در شایستگی های یادگیری، اختلال در مهارت های اجتماعی و مشکلات عاطفی/رفتاری ارتباط معناداری مشاهده نشد (0٫05<p)؛ اما مشخص شد، بین میزان فعالیت بدنی و اختلال در عملکرد اجرایی رابطه منفی و معناداری وجود داشت (0٫040=p، 0٫143-=r).

    نتیجه گیری

    براساس نتایج پژوهش حاضر، میزان فعالیت بدنی رابطه منفی و معناداری با اختلال در عملکرد اجرایی کودکان دارد؛ بنابراین تقویت شرایط فعالیت بدنی براساس نیازهای عملکرد اجرایی کودکان به والدین و معلمان توصیه می شود تا درنهایت عملکرد اجرایی تقویت شود. عملکرد اجرایی، مهارتی شناختی سطح بالا برای موفقیت کودک در زندگی و تمام جنبه های آن است.

    Background & Objectives

    The developmental and social changes between the ages of 7 and 15 are very prominent. In this period, the possibility of developmental and mental disorders is also high. Typically, physical activity is introduced as a low–cost and effective method to help with developmental disabilities. Physical activity has many positive effects on physical and mental health. It has been estimated that about 80% of teenagers do not do enough physical activity. Overall, this study provides a comprehensive and gestalt view of middle childhood and pre–adolescence developmental disabilities regarding the amount of physical activity. Finally, considering the conflicting results regarding the Relationship between the amount of physical activity and the developmental disabilities of children and adolescents, we examined the Relationship between the amount of physical activity and developmental disorders in 7– to 15–years–old children and adolescents living in Hamedan City, Iran.

    Methods

    This was the correlational description study. The data of this study were collected using a cross–sectional method in the community of healthy school–aged children from March to May 2021. The Research Ethics Committee of the Sports Sciences Research Institute reviewed the research. It was approved according to compliance with Ethical Standards in Research of the Ministry of Science, Research and Technology, with the code IR.SSRI.REC.1401.1923. The inclusion criteria were as follows: age range between 7 and 15 years, not suffering from neurodevelopmental disorders such as attention–deficit/hyperactivity disorder, autism, and developmental coordination disorder, not suffering from sensory and skeletal and muscular defects, and being willing to participate in the study. The exclusion criterion was not answering all the questions in the questionnaires. Questionnaires were designed online and were made available to parents. The participants were invited to participate in the study by advertising in social network groups, verbal advertising, and cultural centers. A total of 177 parents of individuals aged 7 to 15 years participated in this study. Data were collected using the International Physical Activity (Crocker et al., 1997) and Five to Fifteen Questionnaire (FTF)–Parent's Form (Kadesjö et al., 2004). Data was analyzed using the Pearson correlation coefficient in SPSS version 26 software. A significance level of lower than 0.05 was considered for all tests.

    Results

    The results showed no significant relationship between physical activity and motor skills development disorder, perception disorder, language and verbal communication disorder, memory disorder, learning disorder, social skills, and emotional problems (p>0.05). However, the results showed a negative and significant relationship between the duration of physical activity and executive dysfunction (r= – 0.143, p=0.040).

    Conclusion

    According to the findings, duration of physical activity has a negative and significant relationship with children's executive function disorder. Therefore, it is recommended that parents and teachers strengthen the conditions of physical activity based on the needs of children's executive function so that ultimately, executive function, which is a high–level cognitive skill, can be strengthened for the child's success in life and all its aspects.

    سابقه و هدف

    فعالیت بدنی یک نیاز کلیدی برای حفظ سلامتی است. عدم تحرک بدنی با همه گیری جهانی چاقی و بار فزاینده بیماری های غیرواگیر در کشورهای در حال توسعه مرتبط است. هدف از این مرور نظامند بررسی سطح فعالیت بدنی شغلی کارکنان بخش بهداشت و درمان و نوع فعالیت بدنی آنها در طول شیفت کاری می باشد.

    روش کار

    مطالعه به روش مرور نظام مند انجام شد که با جستجوی کلیدواژه های Physical activity, Physical practice, Exercise, Healthcare employees, Healthcare workers, Healthcare Professionals, Healthcare occupational, Level در پایگاه های اطلاعاتی بین المللی Web of Science ، Scopus ،PubMed ، Mbase و Library Cochrane و همچنین، پایگاه های فارسی زبان همچون بانک اطلاعات نشریات کشور، پایگاه اطلاعات علمی جهاد دانشگاهی، پژوهشگاه علوم و فن آوری اطلاعات ایران مقالات جمع آوری گردید. تعداد 28 مقاله براساس معیارهای ورود جهت استخراج داده ها ارزیابی و تحلیل شد.

    یافته ها

    در مقالات مورد بررسی، سطح فعالیت بدنی در میان کارکنان بخش درمان توسط ابزارهای سنجش ذهنی و عینی تعیین گردیده است. در 66 درصد از مقالات مورد بررسی جامعه مورد بررسی پرستاران بودند. بطورکلی کارکنان بخش درمان 80 تا 150 دقیقه از شیفت های کاری را صرف فعالیت هایی با شدت پایین نموده اند.

    نتیجه گیری

    درک میزان و نوع فعالیت بدنی در کارکنان بخش درمان می تواند بر رفاه و ایمنی در محیط کار و رضایت بیماران از خدماتی که دریافت می کنند، تاثیر بگذارد. هرچند در مقالات مورد بررسی انجام فعالیت های شغلی با شدت متوسط در میان کارکنان بخش درمان نیز گزارش شده است، ولی شدت، مدت و توالی این فعالیت ها برای ایجاد اثرات درمانی کافی نمی باشد.

    Background

    Physical activity is a key requirement for maintaining good health. This systematic review aimed to determine the physical activity level and the accumulation of physical activity among health care professionals (HCPs).

    Methods

    The study employed a systematic review approach, conducting keyword searches on databases such as PubMed, Science Direct, Scopus, and Google Scholar. Searching Persian medical articles was carried out via Magiran, Scientific Information Database, IranDoc, and Iranian Registry of Clinical Trials. The search terms included "Physical activity", "Physical practice", "Exercise", "Healthcare employees", "Healthcare workers", "Healthcare Professionals", "Healthcare occupational" and "Level". A total of 29 articles met the inclusion criteria for data extraction and were analyzed.

    Results

    In the reviewed articles, the level of physical activity among the Healthcare Professionals has been determined by subjective (questionnaire, daily physical activity record) and objective (accelerometer, heart rate monitor, pedometer, calorie counter, and sport tester) tools. In 66% of the reviewed articles, the occupation was nurses. Healthcare Professionals physical activity levels largely consist of light-intensity physical activity. They spent 80 to 150 minutes per work shifts in light-intensity physical activity.

    Conclusion

    An understanding of the occupational physical activity levels of Healthcare Professionals can affect the well-being and safety in the work environment and the patient's satisfaction of the services they receive. Although moderate and vigorous-intensity occupational activities among the Healthcare Professionals have also been reported in the reviewed studies, but the intensity, duration and sequence of these activities are not sufficient to therapeutic effects.
