Leisure activity participation among older adults: a review

ABSTRACT As the ageing population grows, the health and well-being of older adults have emerged as critical public concerns. Participating in leisure activities offers significant physical, mental, and social advantages for the elderly. Nonetheless, there’s a noticeable gap in the systematic analysis of these activities’ evolution over time. This bibliometric study delves into the domain of leisure activities for older adults, scrutinising scholarly articles from 1990 to 2023, indexed in SCOPUS. With an analysis of 612 English journal articles, it unveils developmental trends, pivotal themes, and unexplored areas. Highlighted research hotspots include dementia, physical activity, quality of life, life satisfaction, and health promotion, with a strategic blueprint outlining their interconnections and implications for policy and practice. This investigation not only charts the field’s landscape but also offers insightful directions for both scholarly inquiry and practical enhancements, aiming to improve the quality of life for the elderly. It concludes with discussions, managerial implications, limitations, future works, and conclusions to enrich the understanding of leisure activities’ development among older adults.

(Re)claiming subversive spaces on TikTok: the complexities of body activisms within physical activity cultures

ABSTRACT Feminist organising in digital spaces, such as social media, has the potential for activism, resistance, and visibility; yet these spaces continue to be dominated by narrow body representations and shaped by unequal power dynamics. We propose that bodies of difference may find vibrant and difference-affirming homes within their digital communities via innovative algorithm-based social media spheres, such as TikTok. Using a creative methodological mashup that we call a ‘collaborative digital autoethnography’, we explored our experiences of difference-affirming hashtags (e.g. #CurvyGym, #DisabledFitness, #QueerFitness) and creators who shared explicitly inclusive and/or subversive content (e.g. #ThickTocker). Using reflexive thematic analysis and thinking with/through Safiya Noble’s work on algorithms of oppression, we developed four themes: #TheFringe, #(Re)claimingFlesh, #CircleOfSurveillance, and #TheWrongSideOfTikTok. In #TheFringe, we found normatively embodied creators who used TikTok as a space to question normative fitness trends – content that helped build our difference-affirming algorithmic space. In #(Re)claimingFlesh, fat-positive creators used TikTok to unapologetically reveal or grab body fat/flesh, and TikTokkers re-storied their body-related journeys by flipping the script of harmful body surveillance (i.e. #CircleOfSurveillance). Lastly, some creators shared grievances about the (oppressive) algorithms of TikTok that banished them to #TheWrongSideOfTikTok. We provide reflexive accounts of our own embodied differences while exploring the TikTok platform, searching for spaces that affirm our bodies while contending with algorithmic oppression. We conclude by discussing TikTok as a platform where powerful collective activism and revolution can form, yet always in contention with trolling, hate, and harmful algorithms that constrain activist movements within sport, exercise, and health contexts.

Physical Activity and Progression of Coronary Artery Calcification in Men and Women.

Prior cross-sectional studies have suggested that very high levels of physical activity (PA) are associated with a higher prevalence of coronary artery calcium (CAC). However, less is known regarding the association between high-volume PA and progression of CAC over time. To explore the association between PA (measured at baseline and during follow-up) and the progression of CAC over time. This cohort study included data from 8771 apparently healthy men and women 40 years and older who had multiple preventive medicine visits at the Cooper Clinic (Dallas, Texas), with a mean (SD) follow-up time of 7.8 (4.7) years between the first and last clinic visit. Participants with reported PA and CAC measurements at each visit during 1998 to 2019 were included in the study. Data were analyzed from March 2023 to February 2024. PA reported at baseline and follow-up, examined continuously per 500 metabolic equivalent of task minutes per week (MET-min/wk) and categorically: less than 1500, 1500 to 2999, 3000 or more MET-min/wk. Negative binomial regression was used to estimate the rate of mean CAC progression between visits, with potential modification by PA volume, calculated as the mean of PA at baseline and follow-up. In addition, proportional hazards regression was used to estimate hazard ratios for baseline PA as a predictor of CAC progression to 100 or more Agatston units (AU). Among 8771 participants, the mean (SD) age at baseline was 50.2 (7.3) years for men and 51.1 (7.3) years for women. The rate of mean CAC progression per year from baseline was 28.5% in men and 32.1% in women, independent of mean PA during the same time period. That is, the difference in the rate of CAC progression per year was 0.0% per 500 MET-min/wk for men and women (men: 95% CI, -0.1% to 0.1%; women: 95% CI, -0.4% to 0.5%). Moreover, baseline PA was not associated with CAC progression to a clinically meaningful threshold of 100 AU or more over the follow-up period. The hazard ratio for a baseline PA value of 3000 or more MET-min/wk vs less than 1500 MET-min/wk to cross this threshold was 0.84 (95% CI, 0.66 to 1.08) in men and 1.16 (95% CI, 0.57 to 2.35) in women. This study found that PA volume was not associated with progression of CAC in a large cohort of healthy men and women who were initially free of overt cardiovascular disease.

초등학교 저학년 신체활동교육에 관한 담임교사의 경험과 시사점

Objectives This study explored the reality of physical activity education in the lower grades through the experi-ences of elementary school teachers and made suggestions for strengthening and revitalizing physical activity ed-ucation in the lower grades. Methods Four lower elementary school classroom teachers interested in and experienced in physical activity edu-cation were selected as participants in the study, and data were collected through in-dept interviews and analysis of literature and documents. The collected data were analyzed through Yin’s five-step analytical cycle, and the an-alyzed data were subjected to triangulation, participant verification, and peer review to enhance the validity of the study. Results In “Students Growing Up Physically Active,” teachers believed that lower elementary students love to be physically active and that diverse and active physical education can help them adjust to school life and grow physi-cally, mentally, and emotionally. However, in “Teachers who are overwhelmed by physical activity,” teachers felt burdened and challenged to teach physical activity due to a variety of factors. In “Teaching Physical Activity Necessary,” there was a lack of physical activity in the lower elementary curriculum and a lack of physical activity education in schools. Conclusions In order to strengthen and revitalize physical activity education in the lower grades of elementary school, we suggested strengthening the importance of basic movement competency education in the lower grades, implementing systematic physical education in the lower grades, improving awareness of physical activity education in the lower grades, and improving the educational environment.

Historic Cognitive Function Trajectories as Predictors of Sedentary Behavior and Physical Activity in Older Adults.

We examined whether trajectories of cognitive function over 10 years predict later life physical activity (PA), sedentary time (ST), and sleep. Participants were from the Adult Changes in Thought (ACT) cohort study. We included 611 ACT participants who wore accelerometers and had 3+ measures of cognition in the 10 years prior to accelerometer wear. The Cognitive Assessment Screening Instrument (CASI) measured cognition and was scored using item-response theory (IRT). activPAL and ActiGraph accelerometers worn over 7 days measured ST and PA outcomes. Self-reported time in bed and sleep quality measured sleep outcomes. Analyses used growth mixture modeling to classify CASI-IRT scores into latent groups and examine associations with PA, ST, and sleep including demographic and health covariates. Results: Participants (Mean age = 80.3 (6.5) years, 90.3% White, 57.1% female, 29.3% had less than 16 years of education) fell into 3 latent trajectory groups: average stable CASI (56.1%), high stable CASI (34.0%), and declining CASI (9.8%). The declining group had 16min less stepping time (95% CI 0.6, 31.4), 1517 fewer steps/day (95% CI 138, 2896), and 16.3min/day less moderate-to-vigorous PA (95% CI (1.3, 31.3) compared to the average stable group. There were no associations between CASI trajectory and sedentary or sleep outcomes. Declining cognition predicted lower PA providing some evidence of a reverse relationship between PA and cognition in older adults. However, this conclusion is limited by having outcomes at only one time point, a non-representative sample, self-reported sleep outcomes, and using a global cognition measure.

Physical activity levels of pregnant women at the time of diagnosis with gestational diabetes attending a tertiary care hospital in Lucknow City, Uttar Pradesh

: Gestational Diabetes Mellitus (GDM) is one of the pregnancy complications characterized by carbohydrate intolerance that develops or is discovered during pregnancy. Physical inactivity and excessive gestational weight gain have been identified as independent risk factors for maternal obesity and pregnancy-related disorders, such as gestational diabetes. Awareness of the significance of physical activity for bodily and psychological health is vitally essential. The woman and her family members need to be swayed to change with time and let go of their myths and false cultural perceptions that exercise can harm the baby. : To determine the physical activity pattern of pregnant women at the time of diagnosis with GDM. : 188 pregnant women diagnosed with gestational diabetes mellitus was selected for the study. Pregnancy Physical Activity Questionnaire was used to calculate the duration; frequency, intensity, and type of physical activity during current gestational period. An average weekly energy expenditure in Metabolic Equivalent of Task (MET-h-week) was calculated. Demographic data including age, socioeconomic status, parity, literacy and working status were collected. Data was analysed on 188 pregnant women diagnosed with GDM. The physical activity of moderate intensity was less performed by the pregnant women. None of the pregnant women were involved in vigorous type of physical activity. Only light intensity activities were performed by the study participants. The study concluded light intensity activity was commonly carried by pregnant women thus a low level of physical activity was observed during the pregnancy.

Factors associated with the consumption of voluntarily fortified foods with micronutrients by the Portuguese population.

This study aimed to identify the sociodemographic and health-related factors associated with the consumption of voluntarily fortified foods with micronutrients (Mn-FF) by the Portuguese population, using data from the National Food, Nutrition and Physical Activity Survey (IAN-AF 2015-2016). Food consumption, sociodemographic and other health-related factors, and physical activity data were computerised using the You Eat & Move e-platform. Foods consumed by participants and labelled foods reported as consumed were included in the database. Mn-FF were considered all foods containing added micronutrients legally authorised, and MN-FF users were those who consumed at least one Mn-FF on at least one of the dietary recall days. Approximately 57% of the population consumed at least one Mn-FF. Children and adolescents consumed significantly more Mn-FF than older age groups. The primary contributors to Mn-FF consumption were breakfast cereals and fat spreads. Being a child (female OR 2.07 [95% CI: 1.52, 2.83]; male OR 4.80 [95% CI: 3.23, 7.14]) or adolescent (female OR 1.62 [95% CI: 1.78, 2.22]; male OR 4.59 [95% CI: 3.26, 6.47]), having a higher level of education (female OR 1.52 [95% CI: 1.17, 1.99]; male OR 1.85 [95% CI: 1.42, 2.42]) and engaging in regular physical activity (female OR 1.31 [95% CI: 1.09, 1.58]; male OR 1.36 [95% CI: 1.11, 1.68]) were factors positively associated with Mn-FF consumption. Conversely, obesity (female OR 0.76 [95% CI: 0.60, 0.96]), living in predominantly rural areas (male OR 0.70 [95% CI: 0.49, 0.91]) and eating fewer mid-meals per day (female OR 0.60 [95% CI: 0.48, 0.76]; male OR 0.64 [95% CI: 0.49, 0.84]) were associated with lower Mn-FF consumption. Younger age, higher education and physical activity practice were positively associated with Mn-FF consumption. These findings provide important insights on priority factors to be considered when deciding on nutrient fortification policies from both public health and food industry perspectives.

Work-related musculoskeletal complaints: risk factors and impact on work productivity among university administrative employees

BackgroundWork-related musculoskeletal disorders (WMSDs) are a significant workplace problem leading to loss of productivity and disability. Administrative workers perform computer-based tasks for long periods. Consequently, they are at risk of developing musculoskeletal disorders. The objective of this study was to explore the frequency and risk factors of work-related musculoskeletal complaints and their impact on work productivity among administrative employees of Suez Canal University, Egypt.MethodsThis cross-sectional study was conducted on 300 administrative employees through simple random sampling. Data were collected by an interview questionnaire including sociodemographic, work-related data, ergonomic and psychological risk factors, the Nordic Musculoskeletal Questionnaire (NMQ), and the World Health Organization Health and Work Performance Questionnaire (HPQ).ResultsThe frequency of work-related musculoskeletal complaints in at least one anatomical region over the past year was 74.7%. Neck (47.1%), lower back (40.7%), and shoulder (36.3%) were the most reported sites of complaints. Risk factors significantly associated with work-related musculoskeletal complaints were gender, age, physical activity, work experience, workplace stress, sustained body position, awkward posture, and inadequate rest breaks. Logistic regression revealed that older age (OR = 1.039, p = 0.023), being female (OR = 2.175, p = 0.011), and not having adequate rest breaks (OR = 1.979, p = 0.019) were significant predictors for the occurrence of WMSDs. The risk factors of absenteeism include gender, age, marital status, educational level, physical activity, BMI, work experience, and musculoskeletal complaints.ConclusionMusculoskeletal problems were highly prevalent among administrative employees. Being female and not having adequate rest breaks were significant predictors for the occurrence of WMSDs. Ergonomic interventions and improvement of working conditions are recommended to reduce WMSDs.

The influence of perceived stress and motivation on telomere length among NCAA swimmers.

Telomere length (TL) shortening is associated with increased cellular senescence and functional decline with age. Regular physical activity is posited to safeguard against TL shortening, but there is disagreement on how concurrent psychosocial stress may influence this relationship. The current analysis explored whether psychosocial stress is associated with TL differences in highly physically active individuals. TL was measured from capillary dried blood spots collected from Division-I (D-1) and Division-III (D-3) National Collegiate Athletics Association (NCAA) swimmers (N = 28) and non-athlete students from the same schools (N = 15). All participants completed Cohen's Perceived Stress Scale (PSS) and student-athletes completed an additional questionnaire to assess psychosocial factors associated with their lifestyle; The Student Athletes' Motivation towards Sports and Academics Questionnaire (SAMSAQ). Semi-structured interviews further contextualized how student-athletes internalize their stress. There was no significant difference in TL or PSS scores between swimmers and controls. D-1 swimmers reported significantly higher career and student-athlete motivation scores compared to D-3, but non-significantly higher PSS and similar academic motivation scores. Themes from interviews with collegiate swimmers included COVID-19 stress, fear of injury, pressure from academics, expectations to perform, and financial pressures. These themes may have contributed to higher PSS scores in D-1 swimmers compared to D-3 but did not appear to impact their TL. Given differences in perceived stress, sources of stress, and SAMSAQ scores, further analyses with larger sample sizes are needed to better understand how these factors influence human biology and health while engaged in intense physical activity.

Grocery Delivery to Support Individuals With Type 2 Diabetes: Protocol for a Pilot Quality Improvement Program.

People with low income are disproportionately affected by type 2 diabetes (T2D), and 17.6% of US adults with T2D experience food insecurity and low diet quality. Low-carbohydrate eating plans can improve glycemic control, promote weight loss, and are associated with improved cardiometabolic health and all-cause mortality. Little is known about supporting low-carbohydrate eating for people with T2D, although food-as-medicine interventions paired with nutrition education offer a promising solution. This program aims to support the initiation of dietary changes by using grocery delivery and low-carbohydrate education to increase the quality of low-carbohydrate nutrition among people with T2D and food insecurity. This program was a nonrandomized pilot conducted at 21 primary care practices in Michigan. Adults with T2D and food insecurity or low income were eligible to enroll. Patients were referred by primary care clinic staff. All participants received the 3-month program, which included monthly US $80 credits for healthy foods, free grocery delivery from Shipt, and low-carbohydrate nutrition education. Food credits were restricted to the purchase of healthy foods. Education materials, developed in collaboration with providers and patients, included print, digital, interactive web, and video formats. At enrollment, participants completed a survey including demographics, diabetes health, diet and physical activity, and diabetes management and knowledge. After the 3-month program, participants completed a survey with repeat assessments of diabetes health, diet and physical activity, and diabetes management and knowledge. Perspectives on participant experience and perceived program impact, food purchasing behaviors, and use of educational materials were also collected. Diabetes health information was supplemented with data from participant medical records. We plan to perform mixed methods analysis to assess program feasibility, acceptability, and impact. Primary quality improvement (QI) measures are the number of patients referred and enrolled, use of US $80 food credits, analysis of food purchasing behavior, participant experience with the program, and program costs. Secondary QI measures include changes in hemoglobin A1c, weight, medications, self-efficacy, diabetes and carbohydrate knowledge, and activity between baseline and follow-up. This program started in October 2022. Data collection is expected to be concluded in June 2024. A total of 151 patients were referred to the program, and 83 (55%) were enrolled. The average age was 57 (SD 13; range 18-86) years, 72% (57/79) were female, 90% (70/78) were White, and 96% (74/77) were of non-Hispanic ethnicity. All participants successfully ordered grocery delivery during the program. This pilot QI program aimed to improve diet quality among people with T2D and food insecurity by using grocery delivery and low-carbohydrate nutrition education. Our findings may help inform the implementation of future QI programs and research studies on food-as-medicine interventions that include grocery delivery and education for people with T2D.

Dose-Dependent Association Between Body Mass Index and Mental Health and Changes Over Time.

Overweight and obesity affect 340 million adolescents worldwide and constitute a risk factor for poor mental health. Understanding the association between body mass index (BMI) and mental health in adolescents may help to address rising mental health issues; however, existing studies lack comprehensive evaluations spanning diverse countries and periods. To estimate the association between BMI and mental health and examine changes over time from 2002 to 2018. This was a repeated multicountry cross-sectional study conducted between 2002 and 2018 and utilizing data from the Health Behaviour in School-aged Children (HBSC) survey in Europe and North America. The study population consisted of more than 1 million adolescents aged 11 to 15 years, with all surveyed children included in the analysis. Data were analyzed from October 2022 to March 2023. Mental health difficulties were measured by an 8-item scale for psychological concerns, scoring from 0 to 32, where a higher score reflects greater psychosomatic issues. BMI was calculated using weight divided by height squared and adjusted for age and sex. Data were fitted by multilevel generalized additive model. Confounders included sex, living with parents, sibling presence, academic pressure, the experience of being bullied, family affluence, screen time, and physical activity. Our analysis of 1 036 869 adolescents surveyed from 2002 to 2018, with a mean (SD) age of 13.55 (1.64) years and comprising 527 585 girls (50.9%), revealed a consistent U-shaped association between BMI and mental health. After accounting for confounders, adolescents with low body mass and overweight or obesity had increased psychosomatic symptoms compared to those with healthy weight (unstandardized β, 0.14; 95% CI, 0.08 to 0.19; unstandardized β, 0.27; 95% CI, 0.24 to 0.30; and unstandardized β, 0.62; 95% CI, 0.56 to 0.67, respectively), while adolescents with underweight had fewer symptoms (unstandardized β, -0.18; 95% CI, -0.22 to -0.15). This association was observed across different years, sex, and grade, indicating a broad relevance to adolescent mental health. Compared to 2002, psychosomatic concerns increased significantly in 2006 (unstandardized β, 0.19; 95% CI, 0.11 to 0.26), 2010 (unstandardized β, 0.14; 95% CI, 0.07 to 0.22), 2014 (unstandardized β, 0.48; 95% CI, 0.40 to 0.56), and 2018 (unstandardized β, 0.82; 95% CI, 0.74 to 0.89). Girls reported significantly higher psychosomatic concerns than boys (unstandardized β, 2.27; 95% CI, 2.25 to 2.30). Compared to primary school, psychosomatic concerns rose significantly in middle school (unstandardized β, 1.15; 95% CI, 1.12 to 1.18) and in high school (unstandardized β, 2.12; 95% CI, 2.09 to 2.15). Our study revealed a U-shaped association between adolescent BMI and mental health, which was consistent across sex and grades and became stronger over time. These insights emphasize the need for targeted interventions addressing body image and mental health, and call for further research into underlying mechanisms.

Managing the Patient with Psoriasis and Metabolic Comorbidities.

Epidemiological data demonstrate strong associations between psoriasis and metabolic comorbidities, including obesity, hypertension, diabetes mellitus, dyslipidemia, and non-alcoholic fatty liver disease. The presence of metabolic comorbidities significantly influences the selection and effectiveness of pharmacological treatments. Some drugs should be prescribed with caution in patients with metabolic comorbidities because of an increased risk of adverse events, while others could have a reduced effectiveness. The aim of this narrative review is to highlight the challenges that healthcare professionals may face regarding the management of psoriasis in patients with metabolic comorbidities. In the first part of the article, the epidemiological association between psoriasis and metabolic comorbidities and their pathogenetic mechanisms is summarized. The second part describes the efficacy and safety profile of conventional and biologic drugs in patients with selected metabolic comorbidities including obesity, non-alcoholic fatty liver disease/hepatic steatosis, and diabetes. Finally, the role of pharmacological and non-pharmacological interventions, such as diet, alcohol abstinence, physical activity, and smoking avoidance is discussed. In conclusion, the choice of the best approach to manage patients with psoriasis with metabolic comorbidities should encompass both tailored pharmacological and individualized non-pharmacological interventions.

Lifestyle-based subtypes of childhood obesity and their association with cardiometabolic factors: A cluster analysis.

Lifestyle factors play an important role in the development and management of childhood obesity and its related cardiometabolic complications. We aimed to explore childhood obesity subtypes based on lifestyle factors and examine their association with cardiometabolic health. We included 1550 children with obesity from the National Health and Nutrition Examination Survey. Cluster analysis identified obesity subtypes based on four lifestyle factors (physical activity, diet quality, sedentary time and smoking). Multiple linear regression assessed their association with cardiometabolic factors. Five subtypes of childhood obesity were identified: unhealthy subtype (n = 571; 36.8%), physically active subtype (n = 185; 21.1%), healthy diet subtype (n = 404; 26.1%), smoking subtype (n = 125; 8.1%) and non-sedentary subtype (n = 265; 17.1%). Compared with the unhealthy subtype, the physically active subtype had lower insulin and HOMA-IR levels, and smoking subtype was associated with lower HDL levels. When compared with children with normal weight, all obesity subtypes had worse cardiometabolic profile, except the physically active subtype who had similar DBP, HbA1c and TC levels; smoking subtype who had similar TC levels; and healthy diet and non-sedentary subtypes who had similar DBP levels. Children of different lifestyle-based obesity subtypes might have different cardiometabolic risks. Our new classification system might help personalize assessment of childhood obesity.

A study of the effect of half-day climatotherapy on changes in salivary cortisol levels.

In our previous study setting, climatotherapy programme consisted of six sessions - four in the mid-mountain area and two in a flat park. For all sessions, the subjects underwent climatotherapy in the morning under slightly cool conditions. During each session, the subjects' blood pressure, pulse rate, skin temperature, blood lactate, salivary cortisol and mood profile were recorded, and meteorological data were collected at the sites. We hypothesised that exercise habits, changes in mood profile and effective temperatures during the session, and physical exertion during the climatic terrain cure would affect salivary cortisol levels. Subjects were 30 (spring) and 29 (autumn). Multiple linear regression analyses were performed to examine the determinants of the change in salivary cortisol levels. In the mountain setting, salivary cortisol was elevated, even though the sessions took place in the descending phase of the circadian salivary cortisol variation; however, the post-session cortisol increase was not significant. Increased post-session salivary cortisol was significantly associated with female gender, older age, higher BMI, lower body fat, less daily physical activity, increased blood lactate, increased 'Tension-Anxiety' and 'Depression-Dejection' moods, and decreased 'Anger-Hostility' mood. The increase in cortisol may have been due to older age, a predominance of females, and the increased blood lactate due to the mountainous terrain. In the flat park, the significant decrease in postsession salivary cortisol was related to the descending circadian phase of circadian cortisol variation and the low physical demands of the sessions.

Investigating young children’s physical activity through time and place

BackgroundPrevious research indicates the start of primary school (4-5-year-old) as an essential period for the development of children’s physical activity (PA) patterns, as from this point, the age-related decline of PA is most often observed. During this period, young children are exposed to a wider variety of environmental- and social contexts and therefore their PA is influenced by more diverse factors. However, in order to understand children’s daily PA patterns and identify relevant opportunities for PA promotion, it is important to further unravel in which (social) contexts throughout the day, PA of young children takes place.MethodsWe included a cross-national sample of 21 primary schools from the Startvaardig study. In total, 248 children provided valid accelerometer and global positioning (GPS) data. Geospatial analyses were conducted to quantify PA in (social) environments based on their school and home. Transport-related PA was evaluated using GPS speed-algorithms. PA was analysed at different environments, time-periods and for week- and weekend days separately.ResultsChildren accumulated an average of 60 min of moderate-to-vigorous PA (MVPA), both during week- and weekend days. Schools contributed to approximately half of daily MVPA during weekdays. During weekends, environments within 100 m from home were important, as well as locations outside the home-school neighbourhood. Pedestrian trips contributed to almost half of the daily MVPA.ConclusionsWe identified several social contexts relevant for children’s daily MVPA. Schools have the potential to significantly contribute to young children’s PA patterns and are therefore encouraged to systematically evaluate and implement parts of the school-system that stimulate PA and potentially also learning processes. Pedestrian trips also have substantial contribution to daily MVPA of young children, which highlights the importance of daily active transport in school- and parental routines.

The effect of exercise therapy as a tool for preventing and treating musculoskeletal disorders among school-aged children: a randomised controlled trial

BackgroundChildren spend a lot of time in school, and there are many ergonomic hazards and postural malalignments that put children at greater risk of developing musculoskeletal disorders (MSDs). This study aimed to investigate the effect of exercise therapy on preventing and treating musculoskeletal disorders among school-aged children.MethodThis randomised controlled trial included 212 (121 boys and 91 girls) school-aged children aged 13–15 years assigned to treatment (n = 106) and prevention (n = 106) groups, where the treatment group contained individuals with MSDs and prevention group contained individuals without MSDs. In each group, half of the individuals received exercise therapy (50 min per session, four times per week, for an 8-week), and others continued their daily lives. MSDs and physical activity were assessed by the Teen Nordic Musculoskeletal Screening Questionnaire and the International Physical Activity Questionnaire-Short Form, respectively, at baseline and after the experimental protocol.ResultsThere was a statistically significant reduction in the frequency of MSDs in the treatment group and occurring MSDs in the prevention group (P ≤ .05). Also, there was significant improvement in all variables of walking, moderate physical activity, vigorous physical activity, and total in intervention groups spatially in students who received exercise therapy (P ≤ .05).ConclusionsThis study demonstrated the effectiveness of exercise therapy in reducing and preventing MSDs and improving physical activity levels among school-aged children aged 13–15 years.Trial registrationsEthical Committee of Shahrekord University (IR.SKU.REC.1401.022) (registration date: 31/05/2022).

Physically active learning for children with learning disorders attending special-needs schools: A program evaluation

BackgroundPhysically active learning (PAL) is a potentially valuable method to stimulate academic performance and physical activity (PA) in children with learning disorders (LD) attending special-needs schools. It is yet unknown whether PAL can be successfully implemented in special-needs schools. AimsThis study aimed to evaluate a PAL-program in special-needs schools by examining teacher’s dose delivered, children’s dose received, and associations of children’s characteristics with dose received. MethodsChildren (N = 37) from two special-needs schools participated in a six-week PAL-program. Dose delivered was evaluated based on PAL-lessons’ implementation rate and duration. Dose received was assessed through time-on-task observations (n = 23) and PA (n = 37). To assess the association between dose received and children’s characteristics (sex, behavioral disorders, motor skills, and physical fitness), Mann-Whitney U tests and Spearman’s rho correlations were used. ResultsFor teacher’s dose delivered, the implementation rate exceeded 95%, and the PAL-lessons lasted the intended 12 minutes. For dose received, children’s on-task behavior was above 79%, and children spent 43% of the time in moderate-to-vigorous PA during PAL. Motor skills were positively related to on-task behavior related to the movements, and physical fitness was positively related to moderate-to-vigorous PA. ConclusionsPAL was successfully implemented in terms of dose delivered and dose received for children with LD attending special-needs schools.

Physical activity to reduce the burden of frailty after menopause: effectiveness and adherence rate of a resource saving exercise plan.

Frailty may be increased by menopause. Physical activity has been proposed to reduce frailty, but poor adherence and cost limit effectiveness. We aimed to investigate both the effectiveness against the frailty burden and the adherence rate of a multicomponent physical activity scheme partially managed by the participating women themselves. Prospective controlled study consisting of a twice-weekly group physical activity scheme divided into two consecutive periods, one supervised by a health professional (12 wk) and the other supervised by the women themselves (36 wk). Group cohesion and mutual support during the patient-only period were aided by social networking via smartphones. Community-dwelling postmenopausal women were divided into a physical activity group (PAG = 126) and a usual activity control group (UAG = 126), both assessed at baseline and at the end of the study. Participants self-assigned to one of the two study arms. Overall, women in the PAG were more likely to improve their frailty status (60.2% vs 42.6%, P < 0.05). The frailty reversal rate from prefrail to robust was significantly higher in the PAG than in the UAG (34.04 vs 8.00%, P < 0.05). Logistic regression confirmed that women in the PAG were more likely to improve their frailty phenotype (odds ratio [OR], 9.12; 95% confidence interval [CI], 3.45-31.52; P < 0.001). Adherence, defined by participants attending 75% of sessions, was attained by 56.35% of women at 48 wk. A physical activity scheme implemented to improve frailty proved effective and attained acceptable adherence. Conditions in the peer-supervised 36-wk phase may increase sustainability.

Assessment of nutritional status, physical fitness and physical activity of school going adolescents (12–15 years) in Delhi

BackgroundAdolescence is a distinct period that is crucial for setting the foundation for long-term health.ObjectiveTo assess the nutritional status, physical fitness, and physical activity of adolescents.MethodsThe present cross-sectional study recruited 100 adolescents purposively. Information regarding general profile and lifestyle-related factors was collected using a questionnaire. Anthropometric data such as height, weight, BMI, and body fat% were collected using appropriate equipment. Physical fitness was assessed using a battery adapted from FITNESSGRAM® and PAQ-A assessed the physical activity. Dietary intake was analysed using a 2-day 24-hour dietary recall.ResultThe study revealed, 19% of the participants were overweight and 6% were obese. The majority (74%) were physically inactive and 15% had high body fat %. There was lower consumption of energy, carbohydrates, iron, and calcium, than the recommendations. Also, physical activity scores were negatively associated with macronutrient intake and trunk lift (strength and flexibility) [p < 0.05]. Data showed lower physical fitness scores. BMI and hand-grip strength was positively correlated [p < 0.05]. Push Ups (endurance) and Standing Broad Jump (power) showed a negative correlation with body fat%. Tennis ball throw and PACER (cardiorespiratory fitness) were positively associated with protein intake. A multiple regression analysis significantly showed that a unit increase in cell phone usage increases body fat% by 11.64 units. Standing broad jump increases by 38.6 cm and decreases with 28.76 cm with a unit increase in playing outside and tuitions timings respectively.ConclusionPoor nutritional status, physical fitness, and physical activity were reported among adolescents. It is imperative to plan intervention strategies to improve the overall health of adolescents.
