Incidental Physical Activity and Physical Fitness Associate with Sustained Attention and Impulse Control in Older Adults

Age-related changes have been observed in sustained attention and impulse control. Deficits in these functions are related to pathological aging. However, research suggests that an active lifestyle may exert a protective effect on cognition in aging. While the association between physical activity and cognitive functioning in older adults has been previously described, few studies have explored the relationship between incidental physical activity and fitness with sustained attention and impulse control in this population. Therefore, this study aimed to evaluate the association between incidental physical activity and various components of fitness and sustained attention and impulsivity in older adults. Fifty-four older adults were recruited (41 females and 13 males) with a mean age of 76.76 years (SD = 8.94). Physical activity levels were assessed using the Yale Physical Activity Survey (YPAS), physical function in healthy older adults was evaluated with the Senior Fitness Test, and sustained attention and impulsivity were measured using a computerized continuous performance task. Significant correlations were found between higher energy expenditure during housework and yardwork activities, and fewer commission errors and shorter reaction times during sustained attention task, and higher sensitivity during impulse control task (rho between 0.35 and 0.40, p < .01, β = 0.80). Additionally, higher scores between agility and balance were associated with better accuracy during the sustained attention task, and faster speed processing correlated to better performance impulse control task (rho between 0.33 and 0.36, p < .05, β = 0.80). Our study highlights the importance of incidental physical activity and various components of fitness on sustained attention and impulse control in aging.

Objectively Measured Physical Activity and Sedentary Behaviour on Cardiovascular Risk and Health-Related Quality of Life in Adults: A Systematic Review.

This systematic review analysed the association between objectively measured physical activity and sedentary behaviour with cardiovascular risk and HRQoL in adults without previous CVD. Additionally, we analysed the impact of the intensity of the physical activity in this association. The search was carried out in three electronic databases with access until February 2023 to find studies with an observational design. For quality assessment, we used The National Institute of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. We identified 5819 references, but only five studies were included. One study shows a positive association between physical activity and HRQoL, while sedentary behaviour was negatively related to HRQoL. Another study showed an association between high-intensity physical activity with a better physical component of HRQoL and low-intensity physical activity with a better mental component of HRQoL. Three studies concluded that higher levels of physical activity are associated with lower levels of cardiovascular risk and higher levels of sedentary behaviour are associated with higher levels of cardiovascular risk. Our findings suggested that people who spend more time being active and spend less time being sedentary appear to have lower cardiovascular risk and higher HRQoL.

Weight loss interventions for patients with prostate cancer: a scoping review.

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review Guidelines were used to conduct a scoping review of weight loss interventions for patients with prostate cancer, with the goal to ascertain the impact of these interventions on body weight, body composition, metabolic biomarkers, and prostate cancer-related outcomes. Six bibliographical databases were searched. Eligible studies included articles reporting weight loss behavioral interventions with at least dietary change as an intervention component, body weight as an outcome, and interventions not solely focused on weight loss maintenance. Patients with prostate cancer of any stage were included. At least 2 independent reviewers used a data-charting form to extract study characteristics and results. A total of 12 studies were included. The sample consisted predominately of White patients with prostate cancer (multiple stages) in the United States. Most interventions included both dietary and physical activity components and were delivered 1-on-1 in-person and/or by telephone. Most of the studies reported that participants experienced significant weight loss and beneficial body composition changes, with a higher proportion of studies with a longer intervention period and dose (time) reporting greater magnitude of changes in outcomes. There were mixed results regarding the interventions' impact on metabolic biomarkers and prostate cancer-related outcomes. Understanding the impact of weight loss interventions on patients with prostate cancer is important. Studies including metabolic biomarkers, prostate cancer outcomes, and more diverse populations are needed.

Evaluating recommendation-based dietary and physical activity strategies for prostate cancer prevention: a target trial emulation in the Health Professionals Follow-up Study.

The 2018 World Cancer Research Fund/American Institute for Cancer Research recommends sustained strategies of physical activity and diet for cancer prevention, but evidence for long-term prostate cancer risk is limited. Using observational data from 27,859 men in the Health Professionals Follow-up Study, we emulated a target trial of recommendation-based physical activity and dietary strategies and 26-year risks of prostate cancer, adjusting for risk factors via the parametric g-formula. Compared with no intervention, limiting sugar-sweetened beverages showed a 0.4% (0.0-0.9%) lower risk of lethal (metastatic or fatal) disease and 0.5% (0.1-0.9%) lower risk of fatal disease. Restricting consumption of processed foods showed a 0.4-0.9% higher risk of all prostate cancer outcomes. Estimated risk differences for clinically significant disease were close to null for strategies involving fruits and non-starchy vegetables, whole grains and legumes, red meat, and processed meat, as well as under a joint strategy of physical activity and diet. Compared with a "low adherence" strategy, maintaining recommended physical activity levels showed a 0.4% (0.1-0.8%) lower risk of lethal and 0.5% (0.2-0.8%) lower risk of fatal disease. Adhering to specific components of current physical activity and dietary recommendations may help to prevent lethal and fatal prostate cancer over 26 years.

Self-Perception Profile, Body Image Perception and Satisfaction in Relation to Body Mass Index: An Investigation in a Sample of Adolescents from the Campania Region, Italy.

(1) Background: Body image dissatisfaction has been commonly reported in adolescents with overweight/obesity and has been related to a lack of motivation to change lifestyle behaviors. Plus, a better perception of physical fitness has been related to a higher self-perception in physical aspect and social items in youths. (2) Methods: A total of 120 (59.2% males, mean age of 12.3 ± 0.9 years) middle-school adolescents participated in the present study. Anthropometric measurements were assessed following the standard procedures. Body weight perception and body image satisfaction were assessed using the Silhouette Figure Body Images Test. Self-perception profile, perceived physical fitness, and perceived difficulties in conducting physical tasks were assessed by using structured questionnaires. (3) Results: Overweight was present in 27.5% adolescents and obesity in 32.5%. A total of 89.7% of adolescents with obesity did not have a real perception of his/her weight status and 84.6% of adolescents with obesity were not satisfied with his/her body image. The self-perception of physical appearance, perceived difficulties in running, perceived overall fitness, and perceived speed/agility were lower in adolescents who were unsatisfied with their body image. Body image satisfaction was positively associated with the self-perception of physical appearance and overall fitness and negatively associated with perceived difficulties in running, independently of sex, age, and BMI. (4) Conclusions: Adolescents with obesity did not have a real perception of their weight status and were unsatisfied with their body image. The positive association between body satisfaction, a better perception of overall fitness, and less difficulties in conducting physical tasks suggests the protective role of the components of physical activity and health-related fitness on body acceptance in a critical period of life.

Effectiveness of a program to lower unwanted media screens among 2-5-year-old children: a randomized controlled trial.

Limited interventions exist on reducing unwanted screen time (ST) among children from low- and middle-income countries (LMICs), so we developed and assessed the effectiveness of the program to lower unwanted media screen time (PLUMS) among children aged 2-5 years in Chandigarh, Union Territory, North India. An open-label randomized control parallel group trial per CONSORT guidelines was conducted among randomly selected 340 families with children aged 2-5 (±3 months) years in Chandigarh, India. PLUMS was implemented at the family level with a focus on modifying the home media environment and targeted individual-level interventions using parent and child modules for 2 months. A post-intervention (immediately) and a follow-up assessment after 6 months was done. During the follow-up period, the interaction was done passively via WhatsApp groups. The control group received routine healthcare services. Validated and standardized tools, including a digital screen exposure questionnaire with a physical activity component, preschool child behavior checklist, and sleep disturbance scale for children, were used to collect data at baseline, post-intervention, and follow-up periods. The primary outcome was the mean difference in ST (minutes/day) among children in the intervention group versus the control group. Generalized estimating equation (GEE) analysis was performed to adjust for clustering. An equal number of families (n = 170) were randomly assigned to the intervention and control arms. In the post-intervention assessment, 161 and 166 families continued while, at the follow-up assessment, 154 and 147 were in the intervention and control arm, respectively. The mean difference in ST on a typical day [27.7 min, 95% Confidence Interval (CI) 5.1, 50.3] at the post-intervention assessment significantly (p < 0.05) decreased in the intervention (102.6 ± 98.5 min) arm as compared with the control (130.3 ± 112.8 min) arm. A significant reduction in ST (β = -35.81 min, CI -70.6, -1.04) from baseline (β = 123.1 min) to follow-up phase (β = 116 min) was observed in GEE analysis. The duration of physical activity increased both at post-intervention (β = 48.4 min, CI = +6.6, +90.3) and follow-up (β = 73.4 min, CI = 36.2, 110.5) assessments in the intervention arm. The PLUMS intervention significantly reduced the children's mean ST on a typical day and increased the physical activity immediately post-intervention and during the 6-month follow-up period. These results might guide the policymakers to include strategies in the national child health programs in the Southeast Asia Region to reduce unwanted ST.Clinical trial registration: https://clinicaltrials.gov/, identifier CTRI/2017/09/009761.

Physical activity and body composition risk for metabolic syndrome

Metabolic syndrome is one of the main risk factors for various diseases such as cardiovascular disease and diabetes. The effect of physical activity has been widely studied regarding its benefits in reducing the development of metabolic syndrome. However, there are still underlying shortcomings in the results of previous research. Objective: to assess the influence of physical activity and metabolic syndrome components on the risk of metabolic syndrome in workers. Cross-sectional research was conducted on employees of PT. PLN. Variables assessed include waist circumference, arm circumference, body mass index (BMI), blood pressure, blood glucose and total cholesterol. Physical activity assessment was carried out using the Global Physical Activity Questionnaire (GPAQ). A total of 40 employees were included in this study. A total of 18 respondents (45%) were at risk of metabolic syndrome. The majority of metabolic syndrome components in employees are overweight (50%), excessive arm and waist circumference (85% and 65%, respectively). The majority of respondents had moderate physical activity (57.5%) and high activity (27.5%). Excessive arm and waist circumference had a significant relationship with the risk of metabolic syndrome in respondents (p &lt; 0.05), however, physical activity did not affect the risk of metabolic syndrome. It is hoped that further research in broader populations will be needed to assess risk factors for metabolic syndrome in workers.

ADULT PHYSICAL ACTIVITY, SEDENTARY BEHAVIOUR AND SLEEP QUALITY IN THE DIGITAL TRANSFORMATION ERA

The digital transformation era increases population health risks associated with lack of exercise, as well as emphasizes the role of an active lifestyle within sustainable socio-economic development. Digitalization is one of the main reasons for setting significant public health priorities: poor or insufficient sleep and physical inactivity. The aim of the research was to study the physical activity (PA), sedentary behaviour (SB) and sleep duration of the population measured by a tri-axial accelerometer. Methods: The study is based on the project “EUPASMOS”, where PA, SB, and sleep-time of the participants (n = 369) was measured 24/7 by a tri-axial accelerometer (UKK RM42, UKK Terveyspalvelut Oy, Tampere, Finland) for a week-long period. The participants mostly spent their waking hours in a sedentary state. The mean duration of sedentary behaviour was 7h 52min. The participants took an average of 9584 steps a day. They also engaged in light PA for 4h 15min, and moderate-to-vigorous PA for 1h 16min. The mean duration of sleep was 5h 46min. The results showed that the insufficient sleep and physical inactivity of the participants are serious health risks in the digital transformation era. Future research should focus on the effect that various components of physical activity (dose, mode, timing) have on sleep.

Formative research to adapt a cardiac rehabilitation program to breast cancer survivors: the heart health after cancer treatment (HEART-ACT) study.

Breast cancer survivors are disproportionately at risk for cardiovascular disease; exercise-based interventions may improve cardiovascular health. The objective of this formative research is to better understand the needs of patients and barriers to participation in an adapted cardiac rehabilitation program for diverse breast cancer survivors in an urban safety net setting. We recruited 30 participants (10 English-speaking, 10 Spanish-speaking, and 10 Cantonese-speaking) who had received treatment with curative intent for breast cancer from an urban safety net hospital between November 9, 2021, to August 30, 2022. Participants completed surveys and interviews about perspectives on health behaviors and participating in an adapted cardiac rehabilitation program. Interviews were qualitatively analyzed using rapid template analysis with pre-selected constructs from the Theory of Planned Behavior, Unified Theory of Acceptance and Use of Technology, and Consolidated Framework for Implementation Research, as well as emergent codes. We developed a Participant User Journey for a program based on responses and conducted human-centered design sessions with 8 participants to iteratively revise the Participant User Journey. Among 30 participants, mean age was 56.7 years (standard deviation [SD] 10.2) with 100% female sex assigned at birth; 1 participant withdrew before completing study procedures. Most participants had limited health literacy (18/29, 62%). Mean body mass index was 31.4 (SD 8.3), 21/29 (72%) had blood pressure below 140/90 mmHg, and 12/29 (41%) had blood pressure below 130/80. Mean 6-minute walk distance was 384.9 meters (SD 78.3). The desired benefits of a program included healthy living and prevention of cancer recurrence. Barriers to participation included motivation, social support, transportation, and concerns about exercise safety. Participants emphasized the need for practicality, such as fitting physical activity into daily life and nutrition support, including recipes and shopping lists. Trusted experts and cultural and language concordance were viewed as important aspects of the program. Through participant interviews and human-centered design sessions, we developed the HEART-ACT program, a 12-week multi-disciplinary program addressing physical activity, nutrition, emotional well-being, cardiovascular risk, survivorship, and other components if indicated (e.g., tobacco cessation). Future research will test the effects of this program on patient-centered outcomes.

The EmpowerHER Program: Developing a Curriculum to Foster Social-Emotional Learning and Physical Activity Among Adolescent Girls in a Summer Care Program

ABSTRACT Programs integrating social-emotional learning (SEL) and physical activity (PA) can contribute to positive behavior outcomes and development for adolescent girls. The purpose of this article is to report the development of the EmpowerHER Program curriculum. Specifically, this curriculum describes implementation strategies and activities tailored to adolescent girls while contributing to the literature surrounding health programs addressing PA and SEL components. Adolescent girls (10–14 years old) participated in an eight-session summer program that provided the opportunity to engage in fun-filled activities that encouraged PA and SEL. Strategies from the EmpowerHER program can be applied to curriculum development and program implementations in out-of-school settings to aid in promoting PA enjoyment and engagement for adolescents. This curriculum supports the importance of contextually tailoring a health program to support PA and SEL for adolescent girls.

Appraising the Physical Activity Levels of Saudis with Physical Disabilities: Effects of Disability Type, Mobility Assistive Devices, and Demographic Factors.

Physical activity (PA) has numerous health benefits for individuals with physical disabilities (IWPD). However, it is common for activity levels to fall below the suggested limits. This study aimed to evaluate the prevalence, pattern, and levels of PA among IWPD in Saudi Arabia. It also investigated the effects of individuals' type of disability, mobility assistive devices, and demographic features on PA levels. Data were collected from 238 participants, mostly male (62.2%), aged 39.76 ± 12.19 years. Among them, 19.3% had spinal conditions, 14.7% had progressive muscular dystrophy, 15.1% had multiple sclerosis, 17.6% had cerebral palsy, 16.4% had poliomyelitis, and 16.8% had limb or foot amputations. The participants were assessed using the Arabic version of the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD-AR). The results showed that 62.6% (64.9% of males and 58.9% of females) met the minimum PA guidelines specified by the WHO. The average PASIPD-AR score was 10.33 ± 10.67 MET-hours/day, indicating lower PA levels, and 8.4% of individuals did not participate in any form of PA. Significant discrepancies were detected in disability type and mobility assistive device use after age adjustment. Marital status, education, and occupation greatly affected PA components. Greater attention should be paid to promoting an active lifestyle among IWPD in Saudi Arabia.

Online resources as a source of information for exercise and physical activity in solid organ transplant recipients.

Exercise training post-transplant has been shown to improve physical function and quality of life in solid organ transplant (SOT) recipients. Online resources in the form of websites and videos are commonly used to provide education and instruction on exercise and physical activity in SOT; however, the content and quality of these online resources has not been evaluated. The first 200 websites and videos identified on Google and YouTube using the English search term "exercise and physical activity in solid organ transplantation" were analyzed. Website and video content was evaluated based on 25 key components of exercise and physical activity in SOT as described in established exercise program recommendations. Website and video quality was determined using DISCERN, Global Quality Scale (GQS), and Patient Education Materials and Assessment Tool (PEMAT; threshold for which material is deemed understandable or actionable is >70%). Parametric and non-parametric tests were used to assess website and video characteristics, content, and quality metrics. Forty-nine unique SOT websites (n = 15) and videos (n = 34) were identified, with the two most common categories being foundation/advocacy organizations and scientific resources. The average reading grade level of websites was 13 ± 3. Website and video content scores varied significantly (websites 11.3 ± 6.4; videos 8.4 ± 5.3). DISCERN total score and GQS score were low (median range for DISCERN 2.5-3.0; median for GQS 2.0 for both websites and videos, out of 5). PEMAT understandability and actionability scores were also low across websites and videos (mean range 57%-67% and 47%-65%, respectively). Foundation/advocacy websites had higher content and quality scores compared to scientific organizations and news/media articles. To our knowledge, this is the first comprehensive assessment of online content and quality of website and video resources on physical activity and exercise in adult SOT recipients. There were a limited number of online English patient-directed resources related to physical activity in SOT, most of which only partly captured items outlined in consensus exercise program recommendations and were of low quality and understandability and actionability. This work provides important insight to the English-speaking transplant community on the current state of online exercise health information and provides future direction for resource development.

A Randomized Controlled Cluster Trial of an Obesity Prevention Program for Children with Special Health Care Needs: Methods and Implications.

Children with disabilities have higher prevalence estimates of obesity than typically developing children. The Healthy Caregivers-Healthy Children Phase 3 (HC3) project implemented an obesity prevention program adapted for children with special health care needs (CSHCN) that includes dietary intake and physical activity (PA) components. The primary outcome was a change in dietary intake, PA, and the body mass index (BMI) percentile. Ten childcare centers (CCCs) serving low-resource families with ≥30 2- to 5-year-olds attending were randomized to either the intervention (n = 5) or control (n = 5). The HC3 CCCs received (1) snack, beverage, PA, and screen time policies via weekly technical assistance; (2) adapted lesson plans for CSHCN; and (3) parent curricula. The control CCCs received a behavioral health attention curriculum. HC3 was delivered over three school years, with data collected at five different timepoints. It was delivered weekly for six months in year one. To ensure capacity building, the HC3 tasks were scaled back, with quarterly intervention delivery in year 2 and annually in year 3. Adaptations were made to the curriculum to ensure appropriate access for CSHCN. Given that the program was being delivered during the COVID-19 pandemic, special modifications were made to follow CDC safety standards. The primary outcome measures included the Environment and Policy Assessment and Observation (EPAO) tool, standardized dietary intake and PA assessments, and the child BMI percentile. CCCs are an ideal setting for targeting CSHCN for obesity prevention efforts as they provide an opportunity to address modifiable risk factors.

The Role of Diet and Physical Activity in Shaping COVID-19 Severity: Design, Validation, and Application of a Retrospective Questionnaire.

After the global challenges posed by COVID-19, researchers strived to identify risk factors for severe cases, which lead to various complications-including death. Lifestyle modifications, such as implementing a healthy diet and recommended physical activity, have been shown to be protective against severe COVID-19 cases. Despite an association of a plant-based diet with reduced COVID-19 severity, specific dietary characteristics have not been identified. Also, the methodology for measuring physical activity is variable, with studies overlooking the intensity or the habit components of physical activity. To bridge this gap, our study designed, validated, and applied a retrospective questionnaire with aims of exploring the relationship between lifestyle factors, specifically diet and physical activity, and severe COVID-19. We considered the intensity and years of physical activity habit, which is a limitation of other questionnaires. Results reveal associations of age and BMI with severe COVID-19. An excessive sugar diet was found to be associated with severe COVID-19 and increased symptom duration. We also observed an inverse relationship pattern of moderate- and vigorous-intensity physical activity across case severity, which is absent in walking physical activity. This study lays a foundation for research aiming to identify lifestyle factors that prevent severe COVID-19 cases.

Implementation of recommended treatment for children in weight management programs: Lessons from the stay in treatment study sites

ObjectivesPediatric obesity remains a public health crisis in the United States, exacerbated by the COVID-19 pandemic. There are recommended guidelines for multidisciplinary care, but they remain challenging to implement, even in tertiary care weight management programs. The aim of this analysis is to describe the implementation of these recommendations among four pediatric weight management programs in the United States. MethodsThis report capitalizes on a convenience sample of programs participating in the Stay In Treatment (SIT) Study, a multicenter study to address attrition among pediatric weight management programs in tertiary care, academic institutions in diverse geographic locations. The programs were compared regarding structure, program offerings, and funding support. ResultsThe four programs were interdisciplinary, offered individual and group treatment options, and were family-based. A range of clinicians provided interventions with nutrition, physical activity, behavioral and psychosocial components. Anti-obesity pharmacotherapy and bariatric surgery were offered, when appropriate. None of the programs were self-sustaining; they required institutional and philanthropic support to provide recommended, comprehensive treatment. ConclusionsOngoing state and national advocacy are needed in the US to create consistent coverage for private and public insurance plans, so that high-risk children can have access to recommended treatment.

IJCM_130A: Self-care practices and its determinants among type 2 diabetics- A cross sectional study

Background: Self-care practices that include self-monitoring of blood sugar level, diet management, physical exercise, adherence to medications, and foot care are the cornerstones of diabetes management. Objective: To assess the self-care practices and factors associated with it among type 2 diabetics Methodology: A community-based cross-sectional study was conducted among the 150 known diabetics in a urban PHC between July 2023 and September 2023. Self-care practices among the registered diabetes patients were described in seven domains as recommended by the American Association of Diabetes Educators (AADE). Risk factors were identified using univariate, followed by multivariate logistic regression. The risk for poor self-care score was expressed in odds ratio (OR) with 95% confidence interval (CI) Results: The mean age of the participants was 57 years (SD: 9.5 years). The self-care was prominent in diet modification, physical activity, and physical activity components. The median self-care score of the participants was 14 (IQR = 12.5 to 15.5). Out of 150 diabetic patients studied, about 48 (32%) participants have good self-care scores, 96 (64%) participants have moderate self-care scores and only 6 (4%) participants have poor self- care scores. Conclusion: Our study emphasized on the need for knowledge and awareness to be provided in urban areas regarding diabetes care management and self- care practices. Structured programs need to be planned to improve the attitude and practices of diabetic patients to promote better compliance towards diet, exercise, adherence to drugs, and appropriate foot care.

Exploring the relationship between AM-PAC scores and mobility components in falls and pressure injury risk assessment tools: A pathway to improve nursing clinical efficiency.

Nurses routinely perform multiple risk assessments related to patient mobility in the hospital. Use of a single mobility assessment for multiple risk assessment tools could improve clinical documentation efficiency, accuracy and lay the groundwork for automated risk evaluation tools. We tested how accurately Activity Measure for Post-Acute Care (AM-PAC) mobility scores predicted the mobility components of various fall and pressure injury risk assessment tools. AM-PAC scores along with mobility and physical activity components on risk assessments (Braden Scale, Get Up and Go used within the Hendrich II Fall Risk Model®, Johns Hopkins Fall Risk Assessment Tool (JHFRAT) and Morse Fall Scale) were collected on a cohort of hospitalised patients. We predicted scores of risk assessments based on AM-PAC scores by fitting of ordinal logistic regressions between AM-PAC scores and risk assessments. STROBE checklist was used to report the present study. AM-PAC scores predicted the observed mobility components of Braden, Get Up and Go and JHFRAT with high accuracy (≥85%), but with lower accuracy for the Morse Fall Scale (40%). These findings suggest that a single mobility assessment has the potential to be a good solution for the mobility components of several fall and pressure injury risk assessments.

Physical Activity Components that Determine Daily Life Satisfaction Among Older Adults: An Intensive Longitudinal Diary Study.

Although previous studies have shown that engaging in physical activity can elevate daily life satisfaction, few studies have identified the specific aspects that can result in this. This study examined whether enjoying moderate-to-vigorous intensity exercises with others for a longer time, but not any aspects of non-exercise physical activity, was associated with higher daily life satisfaction among older adults. We conducted an intensive longitudinal diary survey of 182 individuals for 1week and obtained valid data for 853 person-days. The time spent engaging in light and moderate-to-vigorous physical activity at 8:00-11:59, 12:00-15:59, and 16:00-19:59h was measured using an accelerometer. Duration, intensity, timing, social context, and enjoyment of the exercises were assessed based on diary entries. Stratified by non-exercise and exercise days, we conducted multilevel models. On non-exercise days, longer duration of light physical activity from 12:00 to 15:59 at the within-person level was associated with higher daily life satisfaction. On exercise days, longer duration of moderate-to-vigorous physical activity from 12:00 to 15:59 at the within-person level, longer exercise duration at the within-person level, exercising with moderate-to-vigorous intensity, and enjoyment of exercise at both the within- and between-person levels were associated with higher daily life satisfaction. These findings indicate that enjoying moderate-to-vigorous intensity exercise for a longer duration than usual and engaging in non-exercise physical activity in the afternoon are important for elevating older adults' daily life satisfaction.

Identification of the Risk Factors Associated with Low Bone Density in Peri- and Early Postmenopausal Women

Evidence has shown that one of the most prevalent chronic conditions in postmenopausal women is osteoporosis. Despite the development of some medications, there are still safety and adherence concerns, and, thus, attention has been placed on understanding modifiable risk factors for bone loss. This study aimed to examine the differences in various sociodemographic and body composition factors, physical activity components, and nutrient and food group intake levels among peri- and early postmenopausal women with whole-body bone mineral density (BMD) Z-scores greater than and less than zero. This cross-sectional study utilized baseline data obtained from 45 peri- and early postmenopausal women aged 45–60 years old who participated in a 6-month three-arm, randomized, double-blind, placebo-controlled clinical trial that evaluated the effects of blackcurrant supplementation on bone metabolism. Anthropometric data, BMD values obtained via DXA scans, and self-reported demographic, health, dietary, and physical activity data were collected at baseline. Overall, participants with whole-body BMD Z-scores greater than zero had higher body mass indexes (BMIs), lean mass, fat mass, android fat percentages, ratios of trunk fat mass to limb fat mass, resting metabolic rates, relative skeletal muscle indexes, total and occupational physical activity, alcohol intakes, trans fatty acid intakes, and adequacy of potassium intake, but lower adequacy of vitamin E (p &lt; 0.05). In addition, total calorie intake was positively correlated with added sugar, vitamin E, potassium, alcohol, trans fatty acids, calcium, and vitamin D intakes (p &lt; 0.05); whole-body BMD was positively correlated with added sugars (p &lt; 0.05); vitamin D intake was positively correlated with vitamin E, potassium, trans fatty acid, and calcium intakes (p &lt; 0.05); and calcium intake was positively correlated with added sugar, vitamin E, potassium, and trans fatty acid intakes (p &lt; 0.05). These findings suggest that numerous body composition factors, components of physical activity, and dietary factors are related to bone health in adult women in the menopause transition.
