The Effects of Physical Activity Interventions on Children’s Perception: A Systematic Review and Meta-Analysis

Perception is an essential component of children’s psychological development, which is foundational to children’s ability to understand and adapt to their external environment. Perception is also a crucial tool for understand and navigating one’s surroundings, enabling children to identify objects and react appropriately to settings or situations. Substantial evidence indicates that engaging in physical activity is beneficial for the development of children’s perceptual abilities, as the two are closely intertwined. Still, more research is necessary to gain a full understanding of the impact of physical activity on children’s perception. To further identify and quantify the effects of physical activity on a number of specific perceptions in children. Systematic review and meta-analysis. Searches were performed using five online databases (i.e., PubMed, SPORTDiscus, PsycINFO, Web of Science, and Cochrane Library) for articles published up to and including June 2023 to identify eligible citations. A total of 12 randomized controlled trials, encompassing 1,761 children under the age of 12, were analyzed. Overall, physical activity as an intervention showed a notable effect on the development of children’s perceptions. The meta-analysis indicated that participating in physical activity for 30 minutes around, daily, had a greater impact on children’s visual perception and executive functioning than on their motor perception, body perception, and global self-worth (SMD = 1.33, 95% CI: 0.75, 1.91, p < 0.001). The effects of physical activity on children’s perception performance varied by participant characteristics, with physical activity having better effects on body perception and overall self-worth in children who were obese or overweight. Furthermore, physical activity can also enhance executive function and attention in children with developmental coordination disorders. The effects of physical activity on children’s perception performance varied according to the intervention time, with different activity durations resulting in different perception performances. Therefore, parents and educators must prioritize an appropriate length of physical activity time for children to ensure their optimal growth and development.

Lifelong greenspace exposure and ADHD in Polish children: Role of physical activity and perceived neighbourhood characteristics

Previous research found a protective association between greenspace exposure and attention deficit hyperactivity disorder (ADHD) diagnosis, but previous studies did not investigate mediatory pathways involving child physical activity (PA) and environmental perceptions. Here, we examined the association between lifelong exposure to greenspace and ADHD diagnosis and potential underlying mechanisms (i.e., perceived greenspace, PA, neighbourhood social cohesion, and neighbourhood safety) in children aged 10-13 with and without ADHD. The sample (N = 689) was collected within the NeuroSmog case-control study, where children with (N = 203) and without ADHD (N = 486) were recruited from 18 towns in Southern Poland. ADHD diagnosis was ascertained according to the International Classification of Diseases 11th Revision criteria. Greenspace exposure was defined as the percentage of grass and tree cover in 500 m and 1 km buffers around lifelong residential addresses, respectively. Parents reported information about the availability of domestic garden and data on potential mediators was collected with questionnaires. Structural equation modeling was used to examine hypothesized pathways, and their interplay, linking the three greenspace measures to ADHD. We found that greenspace was indirectly related to ADHD diagnosis: tree cover was positively related to PA, and PA was subsequently negatively related to ADHD diagnosis. Tree cover and garden were both associated with higher levels of perceived greenspace, which in turn related to stronger perceptions of neighbourhood social cohesion. Our findings suggest that exposure to greenspace may lead to lower likelihood of ADHD diagnosis indirectly through PA. These findings highlight how providing children with better access to natural environments for PA may support normal neurodevelopment.

Weight perception and weight management via information nudges

Being overweight or obese is a serious public health problem. Misperception of one's own weight status and inertia are major obstacles to weight control. To overcome these two problems, we conduct a randomized controlled trial in which participants are presented with the correct weight category based on their body mass index to remove any weight misperception, and then given six biweekly reminders about healthy diet and physical activity via SMS/email. We find that our intervention reduces individuals’ weight misperception and encourages healthier dietary choices. However, it has little impact on their physical activity. We further show that people who were obese and those who underestimated their weight status in the baseline survey maintain healthier dietary choices for at least six months after the intervention.

Late-in-life Exercise Ameliorates the Aging Trajectory Metabolism Programmed by Maternal Obesity in Rats: It is Never Too Late

BackgroundMaternal obesity (MO) has been shown to adversely affect metabolic, oxidative, reproductive, and cognitive function in offspring. However, it is unclear whether lifestyle modification can ameliorate the metabolic and organ dysfunction programmed by MO and prevent the effects of metabolic syndrome in adulthood. This study aimed to evaluate whether moderate voluntary exercise in the offspring of rats born to obese mothers can ameliorate the adverse effects of MO programming on metabolism and liver function in mid-adulthood. MethodsOffspring of control (CF1) and MOF1 mothers were fed with a control diet from weaning. Adult males and females participated in 15 min exercise sessions five days/week. Metabolic parameters were analyzed before and after the exercise intervention. Liver oxidative stress biomarkers and antioxidant enzymes were analyzed before and after the intervention. ResultsMales showed that CF1ex ran longer than MOF1ex and increased the distance covered. In contrast, females in both groups ran similar distances and remained constant but ran further distances than males. At PND 300 and 450, male and female MOF1ex had higher leptin, triglycerides, insulin, and HOMA-IR levels than CF1. However, male MOF1ex had lower triglycerides, insulin, and HOMA-IR levels than MOF1. Improvements in liver fat and antioxidant enzymes were observed in CF1ex and MOF1ex males and females compared to their respective CF1 and MOF1 groups. ConclusionThese findings suggest that moderate voluntary exercise, even when started in mid-adulthood, can improve metabolic outcomes and delay accelerated metabolic aging in MO-programmed rats in a sex-dependent manner.

Predictors of Urinary and Fecal Incontinence in Prefrail and Frail Older Adults: A Cross-Sectional Study of the FRAGSALUD Project.

Frailty is associated with urinary and fecal incontinence, which are common geriatric syndromes. This study aims to identify health factors associated with incontinence in prefrail or frail older adults living in the community. This multicenter cross-sectional study included 225 older adults (75.0 ± 6.4 years) with prefrailty or frailty based on the 5-component Fried phenotype. Physical function was assessed using the Short Physical Performance Battery (SPPB). Physical activity, inactivity, and sleep were estimated using a wrist-worn accelerometer. Urinary or fecal incontinence was registered using the Barthel scale (urine and bowel items). Multivariable logistic regression analyses, with age as a covariate, were conducted to identify associations of incontinence. In our participants, 27% presented urinary or fecal incontinence with no sex differences (p = .266). Our results showed that age, daily medication count, and number of falls in the previous year independently predicted incontinence in frail and prefrail older adults (p < .05). Some Fried's criteria, including self-reported exhaustion, gait speed, and handgrip strength, were associated with the presence of incontinence (p < .05), but not Fried's classification. The SPPB total score and its isolated variables were significantly associated with the urinary and fecal incontinence (p < .05). However, none of the accelerometer outcomes showed significant associations with incontinence status. According to this study, age, number of medications, and falls (but not sex) are linked to urinary and fecal incontinence in frail or prefrail older adults living in the community, recommending the assessment of physical function using the SPPB rather than estimating daily physical activity, inactivity, or sleep.

The effectiveness of mobile app usage in facilitating weight loss: An observational study.

With increasing rates of global obesity and associated health issues, there is an ever-increasing need for weight management solutions to be more accessible. Mobile applications offer accessible support systems and have the potential to offer a viable and effective weight management solution as an alternative to traditional healthcare models. To evaluate the effectiveness of the SIMPLE mobile application for time-restricted eating in achieving weight loss (WL). User data were analyzed between January 2021 and January 2023. In-app activity was calculated as the proportion of active days over 12, 26 and 52weeks. A day is considered active if it contains at least one in-app action (e.g., logging weight, food, fasting, or physical activity). Users were categorized into four in-app activity levels: inactive (in-app activity <33%), medium activity (33%-66%), high activity (66%-99%), and maximal activity (100%). Weight change among in-app activity groups was assessed at 12, 26, and 52weeks. Out of 53,482 users, a positive association was found between the use of the SIMPLE app and WL. Active app users lost more weight than their less active counterparts. Active users had a median WL of 4.20%, 5.04%, and 3.86% at 12, 26, and 52weeks, respectively. A larger percentage of active users-up to 50.26%-achieved clinically significant WL (≥5%) when compared to inactive users. A dose-response relationship between WL and app usage was found after adjusting for gender, age, and initial Body Mass Index; a 10% increase in app activity correlated with increased WL by 0.43, 0.66 and 0.69kg at 12, 26, and 52weeks, respectively. The study demonstrates that the SIMPLE app enables effective WL directly associated with the level of app engagement. Mobile health applications offer an accessible and effective weight management solution and should be considered when supporting adults to lose weight.

Gestational diabetes mellitus is associated with greater incidence of dementia during long-term post-partum follow-up.

The impact of gestational diabetes mellitus (GDM) on incident dementia is unknown. Our aim was to evaluate the relationship between GDM and all-cause dementia and the mediating effects of chronic diseases on this relationship. This prospective cohort study included women from the UK Biobank who were grouped based on GDM history. Multivariate Cox proportional hazard models were used to explore the associations between GDM and dementia. We further analysed the mediating effects of chronic diseases on this relationship and the interactions of covariates. A total of 1292 women with and 204,171 women without a history of GDM were included. During a median follow-up period of 45 years after first birth, 2921 women were diagnosed with dementia. Women with a GDM history had a 67% increased risk of incident dementia (hazard ratio 1.67, 95% confidence interval: 1.03-2.69) compared with those without a GDM history. According to mediation analyses, type 2 diabetes, coronary heart disease, chronic kidney disease and comorbidities (diagnosed with any two of the three diseases) explained 34.5%, 8.4%, 5.2% and 18.8% of the mediating effect on the relationship. Subgroup analyses revealed that physical activity modified the association between GDM history and dementia (p for interaction=0.030). Among physically inactive women, GDM was significantly associated with incident dementia; however, this association was not observed among physically active women. A history of GDM was associated with a greater risk of incident dementia. Type 2 diabetes partially mediated this relationship. Strategies for dementia prevention might be considered for women with a history of GDM.

Prevention of Parkinson's disease: from risk factors to early interventions.

Parkinson's disease (PD) is a debilitating neurological disorder characterized by progressively worsening motor dysfunction. Currently, available therapies merely alleviate symptoms, and there are no cures. Consequently, some researchers have now shifted their attention to identifying the modifiable risk factors of PD, with the intention of possibly implementing early interventions to prevent the development of PD. Four primary risk factors for PD are discussed including environmental factors (pesticides and heavy metals), lifestyle (physical activity and dietary intake), drug abuse, and individual comorbidities. Additionally, clinical biomarkers, neuroimaging, biochemical biomarkers, and genetic biomarkers could also help to detect prodromal PD. This review compiled available evidence that illustrates the relationship between modifiable risk factors, biomarkers, and PD. In summary, we raise the distinct possibility of preventing PD via early interventions of the modifiable risk factors and early diagnosis.

A domain-oriented approach to characterizing movement-evoked pain.

Movement-evoked pain (MEP) impacts a substantial proportion of US adults living with chronic pain. Evidence suggests that MEP is influenced by numerous biopsychosocial factors and mediated by mechanisms differing from those of spontaneous pain. However, both characteristic and mechanistic knowledge of MEP remain limited, hindering effective diagnosis and treatment. We asked (1) can chronic pain, functional, psychosocial, and behavioral measures be grouped into descriptive domains that characterize MEP? and (2) what relationships exist between biopsychosocial factors across multiple domains of MEP? We formed 6 characteristic domains from 46 MEP-related variables in a secondary analysis of data from 178 individuals (aged 45-85 years) with knee pain. Ratings of pain during 3 functional activities (ie, Balance, Walking, Chair Stand) were used as primary MEP variables. Pearson correlations were calculated to show linear relationships between all individual domain variables. Relationships between variables were further investigated through weighted correlation network analysis. We observed a unique combination of pain characteristics associated with MEP apart from general pain. Notably, minutes doing physical activity were inversely associated with multiple variables within 4 of the 6 domains. Weighted correlation network analysis largely supported our classification of MEP domains. Additional interdomain relationships were observed, with the strongest existing between MEP, Mechanical Pain, and Multiple Pain Characteristics and Symptoms. Additional relationships were observed both within and between other domains of the network. Our analyses bolster fundamental understanding of MEP by identifying relevant mechanistic domains and elucidating biopsychosocial and interdomain relationships.

A nutrition intervention study’s effect to hematology profiles on elderly group in social retirement home

The increase in the elderly brings consequences, including a higher risk of disease. Inappropriate nutritional intake is also known as one of the risk factors related to the elderly's non-communicable diseases, and nutritional intervention is essential to improve the elderly nutritional status and quality of life. It was an interventional study with a before-after one-group approach. The study was conducted for three months (October-December 2021) in three social retirement homes. The intervention given was supplementation with additional protein sources and snacks each day. The biochemistry profiles were taken 2 times: before and after three months of intervention, comprised of HbA1c, lipid, transferrin, creatinine, and blood pressure level. The data will be analyzed for its normality before being processed with paired t-test or Wilcoxon signed rank based on the normality results. The analysis results show that there are significantly lower transferrin levels (p=0.040), an increase in cholesterol level (p=0.000), and low-density lipoprotein (LDL) level increased from 114.05±32.03 to 125.94±31.41 (p=0.000). There is also a remarkable decrease in hemoglobin (p=0.005) and high-density lipoprotein (HDL) levels. Conversely, there are an increase in HbA1C (p=0.007) and triglyceride level (p=0.005). There is no significant difference in creatinine level. We conclude that nutrition interventions have a significant effect on elderly blood profiles. However, to achieve an improvement, the study should consider physical activity and other variables that might be altering the results.

A smart KPI system for reinforcing Sustainable Urban Mobility Plans under pandemic crises

The latest worldwide application of social distancing measures highlighted dramatic effects on the daily life, mobility, well-being, mental health, and economic activity of citizens during the pandemic. Unfortunately, societies were unprepared to confront a pandemic and applied movement restriction measures, often harsh and unbalanced, creating confusion, uncertainty, and annoyance to communities. In this paper, we reviewed a wide array of databases to categorise the mobility management measures implemented internationally in response to the social distancing restrictions that had to be taken during the first wave of the COVID-19 pandemic. Furthermore, to comprehensively assess the measures implemented to contain the COVID-19 pandemic from the perspective of the local community, we conducted focus group interviews with specific population groups that may have been affected to a greater extent. These groups consisted of vulnerable road users, such as mobility-impaired people and people who are facing severe health problems, representatives of the local economy and businesses and representatives of institutional stakeholders and policymakers. Our research showed that in the post-pandemic era, accessibility and not mobility should be at the heart of economic and social welfare. At the same time, the assurance of physical activity, which is strongly associated with the mental health of citizens, and the protection of the local economy are issues of outermost importance. However, local authorities were unprepared to manage these issues and often made fragmented and punitive decisions. By recognising the need for a regional or metropolitan emergency mechanism, this study aims to introduce a new system of indicators specifically adapted to the particularities and challenges encountered during the pandemic, accounts for local communities' unique needs and requirements, and complies with the general principles of Sustainable Urban Mobility Plans (SUMPs). In the future, the SUMP methodology should be revised to be able to handle and manage mobility systems under pandemic conditions.

Assessment of Nutritional status, Anthropometry and Sleep patterns of the Obese patients during pre and post COVID-19 Illness

Background and aimsUntil COVID-19, obesity was the main pandemic of 21 century. To date, there have been 767984989 confirmed cases, and 6943390 include death cases of COVID-19 (WHO). To find the prevalence of Obesity among adults, to adjudge the attitude and behavior of selected subjects towards eating healthy and weight loss during pre- and post-COVID-19. MethodologySubject selection was done through non-probability judgemental sampling. Initially, 70 young adults between 18 - 39 years of age were selected from different localities of Delhi (NCR). The study was conducted based on a questionnaire developed for the survey. Based on the inclusion criteria only 50 subjects were selected for further study. The study was constructed into three phases and the arrangement of subjects was elaborated as under. Phase 1 includes field study, clinical examination, and biochemical analysis, phase II includes the division of experimental and control groups, whereas Phase III includes the pre& post-COVID nutritional status, anthropometric assessment, beverage consumption, and sleep patterns were also assessed. ResultThe nutrition intervention in E3 (balanced diet + nutrient supplement) showed a significant difference with the control group followed by E2 (nutrient supplement) and E1 (balanced diet). Our findings showed that the subjects have Calorie, protein, fat, carbohydrates, sodium, and potassium intake significantly decreased (P= <0.001) during post-intervention, whereas, the fiber, vitamin A, vitamin C, and iron (P= <0.001), and calcium (p=0.006), intake significantly increased during post-intervention. The changes in anthropometric parameters such as waist-to-hip ratio (WHR), body mass index (BMI), and fat% for pre-COVID-19 were higher for both men and women, but after following the dietary recommendation and physical activity found a significant reduction in WHR, BMI, and fat% (P= <0.001) for both men and women. The p-value for subjective sleep quality, sleep latency, habitual sleep efficiency, sleep disturbances, and daytime dysfunction appears to be less than 0.05 which shows that it is significant. The daily consumption of various beverages listed above with a comparison of pre-post intervention, which shows that only for kada the p-value is 0.001 which is less than 0.05 hence it seems significant. The p-value for people with no comorbidity appears less than 0.05, indicating it is significant. majority of participants (12%) with diabetes took comparatively longer than the participants suffering from other comorbidities followed by Hypertension (7%), Hyperthyroidism (4%), Hypothyroidism, and polycystic ovarian disease (PCOD) (3% each) respectively. ConclusionIn the present study, we provided survey data about the key aspects of the nutritional management of COVID-19 (pre-and-post), based on the current knowledge.

A Prerequisite for need of Harmonized Nutrient Reference Values &amp; its Standardized Terminology for Better access of Nutritional Supplements Globally

Abstract: To reduce the risk of insufficient nutrient intake, nutrient reference values for humans are set at the average nutrient need level without a safety margin. The vast majority of nations and areas in the globe set nutritional intake guidelines for their citizens. Currently, no harmonized nutrient reference value has been published, as well as the development of standards cannot be achieved through the use of formalized frameworks or terminology. The study's objective was to create recommendations for appropriate and secure micronutrient intake ranges that could be used to inform dietary advice. As relevant to the study, we examined micronutrient data from food intake surveys from representative nations. The comparison of national standards illustrates that the level of reference values for nutrient for individual countries is dependent on variables such as methodology, data sources, physical activity exemptions, standard body weights, and age range. In the current study, iron, calcium, magnesium, vitamin A, B12, D and folate were identified as the most commonly under-consumed micronutrients. In this article, the level of six countries' standards are compared to the current reference values for nutrients. Further, numerous words for different dietary standards components are discussed, and a final set of harmonized reference nutrient intake for the dietary advice is provided.

Prevalence and disparities in adolescents’ sedentary behavior from twenty-three African countries: evidence from World Health Organization Global School-based Student Health Survey

ObjectivesStudies on sedentary behavior among adolescents in Africa are limited, hindering public health initiatives. The aim of this study was to examine the prevalence, age, gender, country's income level, and sub-regional disparities of sedentary behavior among adolescents in Africa. Study designCross sectional. MethodsAdolescents who participated in the Global School-based Student Health Survey from the 23 participating African countries were included in the study. Sedentary behavior was assessed with a self-reported questionnaire. A meta-analysis using random effect modeling was used to estimate the prevalence, age, gender, country's income level, and sub-regional disparities of sedentary behavior. ResultsSixty three thousand six hundred thirty five adolescents (12–17 years) were included in the analysis. The prevalence of sedentary behavior was 30% (95% CI: 27%–34%) and significantly higher among adolescents in Southern Africa and East Africa compared to adolescents in West Africa and North Africa (Q = 25.15; P < 0.001). No disparities were found for age (Q =1.51; P = 0.22), gender (Q = 0.10; P = 0.75), country's income level (Q = 4.37; P = 0.11), and survey year (Q = 1.03; P = 0.31). The results were heterogeneous between countries. ConclusionsThe results suggest that a significant proportion of adolescents in Africa engage in sedentary behavior, with the highest prevalence found in Southern Africa and East Africa. This highlights the need for context-specific policy design and interventions to increase physical activity engagement and limit sedentary behavior among adolescents in Africa.

A Comprehensive Review on the State of the Art of Breast Cancers in Italy.

Breast cancer (BC) currently represents one of the most prevalent cancers among women worldwide and the leading cause of cancer death among women, also negatively affecting the quality of life (QoL) in patients. Over the past two decades, BC research has led to extraordinary advances in our understanding of the disease, resulting in more effective treatments. However, its occurrence is still increasing. Several new treatments are now under development worldwide, but they are not devoid of well-- known side effects, and a great number of patients develop endocrine resistance. Nevertheless, the design and synthesis of more suitable strategies and new drugs to treat breast cancers, overcome resistance and side effects, and obtain better therapeutic outcomes are needed. In this review, we summarize the therapies and the clinical studies currently ongoing in Italy for the treatment of BCs, mainly HER2+ MBC, HER2-low MBC, and TNBC, focusing on the most recent ones, also in consideration of diverse facets, including some aspects related to QoL. Finally, some studies related to the usefulness of physical activity in BC will be cited.

A mini-review on influence of physical exercise in remodeling the immune mechanism

Exercising on a regular basis has been associated with delay in onset of many lifestyle disorders and chronic conditions. Different types of exercise have varied effects on our innate immune cells, both positively and negatively. Low-intensity exercises like yoga or brisk walking, medium-intensity exercises like swimming or cycling, and long-term high-intensity exercises like playing sports like volleyball or working out in the gym are some examples. The immune system's function is impacted differently by exercise training depending on the type, duration, intensity, and other factors. Exercise training is a double-edged sword that helps the body's immune system by changing the immune cells' post-exercise reaction mechanisms. Regular physical exercise is one of the lifestyle adjustments aimed at minimizing morbidity and mortality associated with contemporary illnesses such as obesity, diabetes, cardiovascular disease, and cancer. Regular leisure exercise training is regarded to be beneficial, but extreme exercise, such as that performed by professional athletes, is thought to have possibly detrimental consequences. This review summarizes current information in the field of exercise-associated alterations of infection susceptibility and indicates knowledge gaps for further investigation. It highlights that long term effects of physical activity shows a positive association with longevity and exercise.

Functional Property and Regulatory Mechanism of Macrophages in Complementary and Alternative Medicine: From Bench to Clinic.

Complementary and alternative medicine (CAM) includes a wide range of treatments that are gaining acceptance among the public. It is increasingly being recognized as a viable option for treating various diseases with minimal side effects. Common avenues of this therapy include herbal medicine, acupuncture, physical exercise, aromatherapy, dietary therapy, and homeopathy etc. Macrophages are highly heterogeneous cells that play multiple regulatory roles. Practices such as herbal medicine, acupuncture, physical exercise, aromatherapy and dietary therapy exert curative effects by modulating the polarization status and the secretory phenotype of macrophages directly. Furthermore, herbal medicine, acupuncture, and physical exercise influence the crosstalk between macrophages and other types of cells, including cancer cells and T cells. Mechanistically, herbal medicine and acupuncture produce curative effects in diverse diseases, including inflammatory diseases and tumors, mainly by influencing the phosphorylation of signaling proteins in macrophages. Therefore, targeting macrophages offers theoretical support for advancing the scientific understanding of this therapy and aids in identifying potential therapeutic options. Hence, in this review, we systematically summarize the different regulations of macrophages in herbal medicine, acupuncture, physical exercise, aromatherapy, dietary therapy and homeopathy, and further highlight the therapeutic potential of targeting macrophages in complementary and alternative medicine.

Accelerometer-Measured Physical Activity, Fitness and Indicators of Cardiometabolic Risk among Rural Adolescents: A Cross-Sectional Study at 15-Year Follow-up of the MINIMat Cohort.

Little is known about the relationship of physical activity (PA) and fitness with cardiometabolic risk among rural adolescents in low- and middle-income countries. Thus, we examined the associations of PA and fitness with selected cardiometabolic indicators along with potential gender-based differences in a birth cohort of rural adolescents from southeast Bangladesh. We utilized data from the 15-year follow-up of Maternal and Infant Nutrition Interventions in Matlab (MINIMat) cohort (n = 2253). Wrist-worn ActiGraph wGT3x-BT accelerometers were used to estimate sedentary time (ST) and PA. Fitness was assessed using: handgrip strength, standing long jump, and Chester Step Test. Anthropometric parameters, systolic blood pressure (SBP), and fasting lipid, insulin and glucose levels were measured. We calculated insulin resistance using the Homeostasis Model Assessment equation (HOMA-IR). Linear regression and isotemporal substitution models were fitted. The adolescents spent 64min/day (inter-quartile range: 50-81) in moderate-to-vigorous physical activity (MVPA). A 10-minute-per-day higher vigorous PA (VPA) was associated with: 4.9% (95% confidence interval (CI): 2.9-6.8%) lower waist circumference (WC), 3.2 mmHg (95% CI: 1.5-4.8) lower SBP, 10.4% (95% CI: 2.9-17.3%) lower TG, and 24.4% (95% CI: 11.3-34.9%) lower HOMA-IR. MVPA showed similar associations of notably smaller magnitude. Except for WC, the associations were more pronounced among the boys. Substituting ST with VPA of equal duration was associated with lower WC, SBP, triglyceride and HOMA-IR. Grip strength was favorably associated with all indicators, displaying considerably large effect sizes. Our findings indicated beneficial roles of PA- particularly VPA- and muscular fitness in shaping cardiometabolic profile in mid-adolescence. VPA and grip strength may represent potential targets for preventive strategies tailored to adolescents in resource-limited settings.

A Systematic Narrative Review of Recent Obesity Interventions with Black Women in the United States.

This study is to comprehensively review recent obesity interventions for Black women in the United States. We searched PubMed and EBSCOhost for articles published between 2013 and 2022 using a comprehensive search strategy. Two reviewers screened titles, abstracts, and full texts. Data from the included articles were extracted.Qualitative themes related to the intervention designs were identified across studies. Fifty-two studies were included in the review. Interventions typically aimed to reduce weight by targeting diet and/or physical activity. Intervention activities were delivered virtually and in-person via several formats including didactic content and interactive sessions. Outcomes were assessed through a variety of research designs. Across papers, we identified six key themes of intervention design: integration of technology, centering community and culture, personalization of content, use of social support, skill-building through intervention activities, and addressing comorbid health conditions. To address the obesity epidemic, future research can build upon key lessons learned from recent interventions tailored to Black women.

C-reactive protein to albumin ratio and risk of incident metabolic syndrome in community-dwelling adults: longitudinal findings over a 12-year follow-up period.

The C-reactive protein to albumin (CRP/Alb) ratio has emerged as a novel biomarker for various inflammatory diseases. This study aimed to evaluate the association between the CRP/Alb ratio and incident metabolic syndrome (MetS) with a large-sample, community-based Korean cohort over a 12-year follow-up period. Among 10,030 participants, a total of 6205 participants aged 40-69 years without MetS were selected from the Korean Genome and Epidemiology Study (KoGES). The baseline CRP/Alb ratio was divided into quartiles. The definition of newly developed MetS was the one proposed by the 2009 Joint Interim Statement of Circulation. Hazard ratios (HRs) with 95% confidence intervals (CIs) for incident MetS were calculated using multivariable Cox proportional hazards regression models after adjusting for potentially confounding variables. During the 12-year follow-up period, MetS developed in 2535 subjects (40.9%, 2535/6205) with an incidence rate of 5.6-11.9 (over 2 years). Compared to the reference first quartiles, the HRs (95% CIs) of incident MetS in the second, third, and fourth quartiles increased in a dose-response manner. Compared to the reference quartile, the HRs (95% CIs) of the incidence of MetS for the second, third, and fourth quartiles of CRP/Alb ratio were 1.12 (0.99-1.27), 1.24 (1.11-1.40), and 1.51 (1.34-1.69) after adjusting for age, sex, smoking status, alcohol intake, physical activity, total cholesterol, mean arterial pressure, HOMA-IR, and total energy intake. High CRP/Alb ratio at baseline may be a useful surrogate indicator of future incident MetS.
