Perceived social support and treatment adherence in Chileans with Type 2 diabetes.

This study aimed to determine if greater perceived social support was directly associated with better Type 2 diabetes (T2D) treatment adherence and if better T2D treatment adherence was related to lower HbA1c levels in Chilean adults with T2D. For this purpose, 200 adults were recruited from the Chilean Diabetic Association. Participants were asked to complete self-report instruments and provide a capillary blood sample to measure HbA1c. Structural equation model analyses were performed to determine direct associations. The study's results indicate that greater perceived social support was associated with healthier dietary habits, regular foot care, more frequent physical activity, and lower medication intake. Likewise, blood sugar testing and physical activity were related to HbA1c. These findings provide evidence of how perceived social support relates to T2D treatment adherence behaviors in Latino patients from South America and could be used for interventions to enhance social support from patients' families, partners, and friends.

Prevalence and Factors Associated With Willingness to Sustain Pandemic-Induced Digital Work in the General Population and Moderating Effects of Screen Hours: Cross-Sectional Study.

The pandemic has accelerated digital work transformation, yet little is known about individuals' willingness to sustain such digital modes and its associated factors. A better understanding of this willingness and its drivers is crucial for guiding the development of future digital work infrastructure, training programs, and strategies to monitor and prevent related health issues. This study aims to quantify the general population's willingness to sustain pandemic-induced digital work, identify its associated factors, and examine how screen time moderates these relationships. A cross-sectional study was conducted targeting Hong Kong residents aged ≥18 years who have increased engagement in digital work since the pandemic. Data were collected through self-reported, web-based surveys. Descriptive statistics determined prevalence rates, while structured multiphase logistic regression identified associated factors and explored the moderating effects of screen hour levels. This unfunded study enrolled 1014 participants from May 2 to June 24, 2022, and completed data analysis within 3 months after data collection. A total of 391 (38.6%; 95% CI 35.6%-41.6%) participants expressed willingness to sustain digital work. Positive factors associated with this willingness included being an employee (odds ratio [OR] 3.12, 95% CI 1.59-6.45; P=.001), being health professionals (OR 3.32, 95% CI 1.49-7.82; P=.004), longer screen hours (OR 1.09, 95% CI 1.03-1.15; P=.002), and higher depression levels (OR 1.20, 95% CI 1.01-1.44; P=.04). Conversely, negatively associated factors included older age (OR 0.87, 95% CI 0.81-0.94; P=.001), extroversion (OR 0.66, 95% CI 0.51-0.86; P=.002), higher eHealth literacy (OR 0.96, 95% CI 0.93-0.98; P<.001), perceived greater susceptibility to COVID-19 (OR 0.84, 95% CI 0.74-0.96; P=.009), residence in a high-severity COVID-19 community (OR 0.73, 95% CI 0.63-0.84; P<.001), having infected individuals in the immediate social circle (OR 0.64, 95% CI 0.46-0.88; P=.006), higher BMI (OR 0.94, 95% CI 0.90-0.99; P=.02), feelings of being out of control (OR 0.96, 95% CI 0.93-0.98; P=.002), and higher fear of COVID-19 (OR 0.96, 95% CI 0.94-0.98; P=.001). In addition, a moderating effect of screen hour level (high: >8 h/d; low: ≤8 h/d) influenced the association among 10 factors related to willingness to sustain pandemic-induced digital work, including age, education level, household size, needs for regular medical care, BMI, frequency of both vigorous and moderate physical activities, perceived COVID-19 severity, immediate social circle COVID-19 presence, and fear of COVID-19 (all P values for interaction <.05). The substantial willingness of the general population to sustain digital work after the pandemic highlights the need for robust telework infrastructure, thorough monitoring of adverse health outcomes, and the potential to expand telehealth services among this group. The identification of factors influencing this willingness and the moderating role of screen hours inform the development of personalized strategies to enhance digital work acceptance where needed.

Associations between Physical Activity Frequency in Leisure Time and Subjective Cognitive Limitations in Middle-Aged Spanish Adults: A Cross-Sectional Study

The effect of forest-environment construction on the physical activity among Chinese adults

The Chinese government attaches great importance to the construction of the National Forest City (NFC), aiming at creating a pleasant living environment beneficial for people’s health and well-being. This study aimed to estimate the effect of the NFC policy on the frequency of physical activity (PA) for people in mainland China. Using the nationally representative data from the China Family Panel Studies in 2010 and its follow-up in 2018, 17 704 participants aged 18 and older were analyzed in our study. We employed the two-way fixed estimator in the difference in difference setting to analyze the PA of the adults in the cohort with different development levels of the forest-environment construction measured by the number of NFCs, and explore the relative differences before and after the construction of NFC. Subgroup analysis of age group, gender and living areas and a series of robustness tests were further conducted. The mean age of 17 704 participants in 2010 was (45.03 ± 13.67) years old, 51.74% of which were female and 48.26% were male. DID results showed that after the construction of NFC, the frequency of PA increased by 1.35 (β = 1.35, 95% CI:0.73–1.98) per week compared to those in provinces without NFC after adjusting covariates. And the improving effect of the forest-environment construction on PA frequency was intensified in middle-aged and older adults aged 45 and above (β = 2.03, 95% CI:1.09–2.96), males (β = 1.26, 95% CI:0.39–2.12) and females (β = 1.49, 95% CI:0.58–2.40) and those living in urban areas (β = 1.29, 95% CI:0.57–2.00). Our findings showed that the forest-environment construction under the NFC strategy has a positive role in the PA of older adults, indicating the health-promoting effects of the national green low-carbon environmental strategy. Considering the heterogeneity, it is essential to promote the benefits of green exercise for young and rural adults.

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.

Effects of Physical Activity on Physical Health, Behavior and Personality by Social Status of Urban and Rural Children: A Systematic Review

This study investigates the impact of physical activity on children's physical health, behavior and personality by considering differences in social status in urban and rural environments. Using mixed methods, we combined surveys, observations and psychological measurements to gain in-depth insights. Involving children of different age groups (12-16 years old) from both neighborhoods (urban and rural), this study looked at the level, frequency, and type of physical activity they engaged in. In evaluating physical health, not only physical aspects such as fitness and body mass index were considered, but also factors such as sleep patterns and eating habits. In addition, the children's behavior and personality were also analyzed using tested measurement tools. This study aims to uncover significant differences and patterns that may emerge between urban and rural children in response to physical activity. The findings from this study are expected to provide an in-depth picture of the complex relationship between physical activity, social status and children's well-being. The practical implication of this study is to develop more focused interventions to promote physical activity in both settings, taking into account their social context. This study is a Systematic Literature Review (SLR) that has been published in the Web of Science, Transport Research International Documentation (TRID), Scopus, Medline, and Google Scolar. Data were analyzed using the process of selecting articles used utilizing the PRISMA. By presenting these findings comprehensively, this study contributes to a better understanding of child health efforts in different urban and rural environments. Physical activity interventions were effective in changing behavior and improving personality traits of children in both urban and rural areas. The importance of adaptation of intervention strategies depending on the environmental context recommends further research: Include more variables, consider psychological aspects in more depth, and explore the role of social factors in intervention success.

Exercise as medicine! Physical activity mitigated the impact of the COVID-19 pandemic on depressive symptoms in adults with depression

We investigated the longitudinal association between physical activity (PA) and symptoms of depression and anxiety in people with depression during the COVID-19 pandemic. We used data from baseline (June 2020) to wave 3 (June 2021) of the PAMPA Cohort, an ambispective cohort with adults in south Brazil. The Hospital Anxiety and Depression Scale assessed depressive and anxiety symptoms in all waves. Participants reported frequency (minutes), type (aerobic, strength, combined), and place (out of home, at home) of physical activity at baseline. Generalized linear models were used to investigate the interaction between time and PA, adjusting for possible confounding variables. Subjective memory decline was assessed using multivariate Cox proportional hazard regression models to obtain adjusted hazard ratio (HR) and respective 95% confidence interval (CI). Participants (n = 424) with self-reported clinically diagnosed depression were included. We observed a non-linear increase trajectory of depression during the first year of the COVID-19 pandemic. PA was associated with a slower trajectory of depressive (slope: −1.89; 95%CI: −3.34, −0.43 points) but not anxiety (slope: −1.33; 95%CI: −2.93, 0.25 points) symptoms during the COVID-19 pandemic. Participants who continued physically active from pre-pandemic in wave 1 showed a lower risk of subjective memory decline during follow-up than those who persisted inactive in the same period (HR: 0.52; 95%CI: 0.30, 0.89). PA attenuated the impact of the COVID-19 pandemic on depressive symptoms in adults living with depression in south Brazil. Regularity of physical activity was associated with fewer depression and anxiety symptoms and a lower risk of subjective memory decline.

Sports preferences in children and adolescents in psychiatric care—evaluation of a new questionnaire

IntroductionAs part of an exploratory and hypothesis-generating study, we developed the Sports Preference Questionnaire (SPOQ) to survey the athletic behavior of mentally ill children and adolescents, subjectively assessed physical fitness and perceived psychological effects of physical activity.MethodsIn a department of child and adolescent psychiatry, we classified 313 patients (6–18 years) according to their primary psychiatric diagnosis. The patients or—in the parental version of the questionnaire—their parents reported their sport preferences on the SPOQ. As possibly influential factors, we also assessed the frequency of physical activity, the importance of a trainer, coping with everyday life through physical activity, and subjectively perceived physical fitness.ResultsOne in 3 patients (32.4%) stated that they were not physically active. Patients diagnosed with eating disorders reported, on average, a notably high frequency (median of 3 h/week) and degree of coping with daily life through physical activity (median of 5 on a 6-point Likert scale). Patients with anxiety disorders and depression had the lowest self-perception of physical fitness (mean value of 3.1 or 3.7 on an interval scala from 0 to 9). The presence of a trainer was generally considered not important, except for ADHD patients (median of 3 on a 6-point Likert scale).ConclusionThe SPOQ is sensitive for differential effects of core child and adolescent disorders as well as for main covariates influencing the complex association between physical activity and emotional and behavioral disorders in children and adolescents. Based on this pilot study, we discussed the need for an efficacy study to measure the effects of sports therapy.

Promotion of Physical Activity by Québec Primary Care Physicians: What Has Changed in the Last Decade?

This study aimed to assess the changes in the frequency of physical activity (PA) counseling and in the predictors of primary care PA promotion in Québec primary care physicians (PCPs) between 2010 and 2020. In 2010, we conducted a survey among Québec PCPs. Questions included: frequency of promoting PA to patients, perceived barriers, needs to improve PA promotion practice, frequency of PCPs' PA practice, and sociodemographic information. In 2020, we took over the 2010 questionnaire to document the evolution of the PA promotion practice. The proportion of PCPs discussing PA with their patients significantly increased (P < .05) in 2020 for the following health conditions: depression, low back pain, chronic obstructive pulmonary disease, and cancer; it declined (P < .05) for overweight patients, those with metabolic syndrome, and in primary prevention. Collaboration with PA professionals was the major need identified, and it increased in 2020. PCPs' own practice of PA was a predictor of PA promotion in 2010 (odds ratio = 6.679; P < .001) and in 2020 (odds ratio = 6.679; P < .001). In both 2010 and in 2020, older or more experienced PCPs were more likely to discuss PA with their patients without diagnosed diseases than younger ones or those with less experience. Over the last 10years, there has been a significant increase in PCPs promoting PA in Québec; however, it has been mainly oriented toward secondary prevention. It is concerning that PA counseling in primary prevention has declined, notably among younger PCPs. The stronger claim for closer collaboration with kinesiologists suggests that PCPs are in favor of an interprofessional strategy, namely collaboration with PA specialists.

Physical activity volume, frequency, and intensity: Associations with hypertension and obesity over 21 years in Australian women

BackgroundOptimal patterns of accrual of recommended levels of physical activity (PA) for prevention of hypertension and obesity are not known. The overall aim of this study was to investigate whether different patterns of accumulation of PA are differentially associated with hypertension and obesity in Australian women over 21 years of age. Specifically, we investigated whether, for the same weekly volume of PA, the number of sessions (frequency) and vigorousness of PA (intensity) were associated with a reduction in the occurrence of hypertension and obesity in women. MethodsData from the 1973–1978 and 1946–1951 cohorts of the Australian Longitudinal Study of Women's Health were analyzed (n = 20,588; 12%–16% with a Bachelor's or higher degree). Self-reported PA, hypertension, height, and weight were collected using mail surveys every 3 years from 1998/2000 to 2019/2021. Cox proportional hazard models were used to investigate the association of PA volume (none; 33–499; 500–999; 1000+ MET-min/week), weekly frequency (none; 1–2 times; 3–4 times; 5–7 times; 8+ times), and the proportion of vigorous PA to total volume of PA (none; 0%; 1%–33%; 34%–66%; 67%–100%) with odds of hypertension and obesity from 2000 to 2021. ResultsThe cumulative incidence of hypertension was 6% in the 1973–1978 and 23% in the 1946–1951 cohort; 27% of women in the 1973–1978 and 15% in the 1946–1951 cohort developed obesity over the period. Overall, a higher volume of PA was associated with reduced odds of hypertension and obesity. When the volume of PA was considered, the odds of hypertension did not vary according to the frequency or intensity of PA. However, increased proportion of vigorous PA to the total volume of PA was associated with a small additional reduction in the risk of obesity. ConclusionPA volume appears to be more important than the pattern of accumulation for the prevention of hypertension and obesity. Incorporating more sessions, particularly of vigorous-intensity PA, may provide extra benefits for the prevention of obesity.

Promoting Awareness of Sedentary Behavior and Physical Activity Awareness Among Rural Youth Through Bocce Game: A Qualitative Study

In youth, it is important to promote physical activity habits. The multifactorial nature of rural areas affects individuals' physical activity habits, and sustainable strategies are needed to promote sedentary behavior and physical activity awareness among rural youth. The research data consists of qualitative interviews with healthy rural youth after the bocce game activity. In-depth interviews were conducted with 11 volunteers who participated in the activity using a semi-structured interview form. Qualitative findings are divided into nine main themes: Thoughts on bocce game activity; meaning of physical activity and thoughts on the topic; physical activity and its effect on health; thoughts on the frequency, duration, intensity, and type of physical activity; meaning of sedentary behavior and thoughts on the topic; sedentary behavior and its effect on health; thoughts on the frequency and duration of sedentary time and the type of sedentary behavior; promoting awareness of sedentary behavior and physical activity through bocce game; expectations from institutions. The findings highlight that bocce is a vital strategy to encourage physical activity and sedentary behavior awareness among youth in rural areas. Local authorities have a critical role in supporting physical activity and sedentary behavior awareness in rural areas.

Impact of Counselling on Coronary Artery Disease Patients Adherence to Medications and Frequency of Physical Activity

Impact of Counselling on Coronary Artery Disease Patients Adherence to Medications and Frequency of Physical Activity

The Association of Body Image Perceptions with Behavioral and Health Outcomes among Young Adults.

This study was conducted on 5 March 2024, by the Universidad Europea de Madrid. This study aims to explore how body image perceptions influence health behaviors and mental and physical health outcomes among a specific group of 605 young adults aged 20 to 35 engaged in strength training regimes. To measure these perceptions, the Multidimensional Body-Self Relations Questionnaire (MBSRQ) was employed, an advanced tool that assesses multiple dimensions of body image through its subscales, including feelings of physical attractiveness, investment in one's appearance, and satisfaction with different body areas. Participants were segmented into two groups based on a median split of their self-reported body image. The survey assessed a diverse array of variables, including demographic details, physiological data, resistance training routines, and psychological attributes. In this revision, we consistently use the term 'dietary habits' to ensure clear and uniform language when discussing eating patterns. Notable differences were observed in dietary habits and exercise engagement, influenced significantly by body image perceptions. Negative body image was linked to less healthy dietary habits, diminished physical activity, and worse psychological outcomes, such as increased anxiety and depression. Conversely, a positive body image was associated with healthier dietary habits, more frequent physical activity, and better psychological health. The findings suggest that interventions aimed at improving body image could be crucial for enhancing overall health within this specific demographic. Due to the non-representative nature of the study group, conclusions are cautiously presented as applicable only to similar populations engaged in strength training. This study underscores the need for holistic strategies that encourage positive body image to improve both physical and psychological health outcomes in young adults.

Eating Behaviors and Physical Activity versus the Big Five Personality Traits in Women with a Hereditary Predisposition to Breast or Ovarian Cancer.

The Big Five personality traits-neuroticism, extroversion, openness to experience, agreeableness, and conscientiousness-represent continuous, individual features that affect a number of vital health aspects, including morbidity, self-reported health status, or lifestyle. The aim of this study was to analyze the relationship between the eating behaviors and engagement in physical activity of women with a hereditary predisposition to breast or ovarian cancer and the Big Five personality traits. A total of 357 women, participants of 'The National Program for Families With Genetic/Familial High Risk for Cancer', were included in the study. In the healthy group, the following statistically significant predictors were found in variables: agreeableness-meal frequency (β = 0.151; p = 0.030); neuroticism-consumption of fruits and vegetables (β = -0.177; p = 0.016) and cereal products (β = -0.223; p = 0.002); openness to experience-consumption of plant-based fats (β = 0.141; p = 0.034) and physical activity (β = 0.153; p = 0.021). In the cancer group, the frequency of dairy consumption (β = 0.286; p = 0.003) and physical activity (β = 0.370; p = 0.000) were found to be statistically significant predictors for the openness to experience variable. Neuroticism is associated with less frequent consumption of fresh fruits and vegetables as well as cereal products. Openness to experience was more often linked with a higher frequency of dairy consumption, plant-based fats, and physical activity. Women with breast or ovarian cancer and a higher openness to experience consumed dairy and engaged in physical activity more often than their peers with the remaining personality traits.

HUBUNGAN KEBIASAAN SARAPAN DAN AKTIVITAS FISIK DENGAN KONSENTRASI BELAJAR SISWA/I KELAS VIII SMPN 28 BATAM TAHUN 2023

Background: Learning concentration is the ability to focus the mind on something without being influenced by the surrounding circumstances. Learning concentration is influenced by two factors, namely internal and external. Breakfast habits and physical activity are included in the internal factors of learning concentration. The purpose of this study was to determine the relationship between breakfast habits and physical activity with the concentration of learning students of grade VIII SMPN 28 Batam. Method: This type of research is quantitative with a cross-sectional approach. The population of this study was class VIII students at SMPN 28 Batam as many as 292 people. The study sample was taken from as many as 72 people with purposive techniques. Data on breakfast habits and physical activity were obtained by questionnaire and study concentration using the Stroop test. The data were analyzed using the chi–square test. Results: Breakfast habits respondents had good breakfast habits by 82.4%. The frequency of physical activity of respondents was categorized at a moderate physical activity level of 45.6%. The frequency of respondents' learning concentration obtained balanced results between good and bad concentration by 50%. The results of the chi-square test obtained p value = 0.525 for the relationship between breakfast habits with learning concentration, and the relationship between physical activity with learning concentration obtained p value = 0.084. Conclusion: There is no significant relationship between breakfast habits and physical activity of grade VIII students of SMPN 28 Batam.

The Health4Life e-health intervention for modifying lifestyle risk behaviours of adolescents: secondary outcomes of a cluster randomised controlled trial.

To investigate the effectiveness of a school-based multiple health behaviour change e-health intervention for modifying risk factors for chronic disease (secondary outcomes). Cluster randomised controlled trial. Students (at baseline [2019]: year 7, 11-14 years old) at 71 Australian public, independent, and Catholic schools. Health4Life: an e-health school-based multiple health behaviour change intervention for reducing increases in the six major behavioural risk factors for chronic disease: physical inactivity, poor diet, excessive recreational screen time, poor sleep, and use of alcohol and tobacco. It comprises six online video modules during health education class and a smartphone app. Comparison of Health4Life and usual health education with respect to their impact on changes in twelve secondary outcomes related to the six behavioural risk factors, assessed in surveys at baseline, immediately after the intervention, and 12 and 24 months after the intervention: binge drinking, discretionary food consumption risk, inadequate fruit and vegetable intake, difficulty falling asleep, and light physical activity frequency (categorical); tobacco smoking frequency, alcohol drinking frequency, alcohol-related harm, daytime sleepiness, and time spent watching television and using electronic devices (continuous). A total of 6640 year 7 students completed the baseline survey (Health4Life: 3610; control: 3030); 6454 (97.2%) completed at least one follow-up survey, 5698 (85.8%) two or more follow-up surveys. Health4Life was not statistically more effective than usual school health education for influencing changes in any of the twelve outcomes over 24 months; for example: fruit intake inadequate: odds ratio [OR], 1.08 (95% confidence interval [CI], 0.57-2.05); vegetable intake inadequate: OR, 0.97 (95% CI, 0.64-1.47); increased light physical activity: OR, 1.00 (95% CI, 0.72-1.38); tobacco use frequency: relative difference, 0.03 (95% CI, -0.58 to 0.64) days per 30 days; alcohol use frequency: relative difference, -0.34 (95% CI, -1.16 to 0.49) days per 30 days; device use time: relative difference, -0.07 (95% CI, -0.29 to 0.16) hours per day. Health4Life was not more effective than usual school year 7 health education for modifying adolescent risk factors for chronic disease. Future e-health multiple health behaviour change intervention research should examine the timing and length of the intervention, as well as increasing the number of engagement strategies (eg, goal setting) during the intervention.

Physical Activity and Local Blue/Green Space Access During the COVID-19 Pandemic.

To examine whether local blue and green space access was associated with weekly physical activity frequency during the COVID-19 pandemic. Cross-sectional. Population-based, nationally representative sample of U.S. adults (May and June 2021). Adults, ages 18-94 (N = 1,771). Self-reported data included the presence of blue spaces (e.g., lakes, outdoor swimming pools, riverside trails) and green spaces (e.g., parks, forests, or natural trails) in their neighborhoods, and days of physical activity per week (e.g., running, swimming, bicycling, lifting weights, playing sports, or doing yoga). Multiple Poisson regression assessed relationships between blue and green spaces and physical activity, with coefficients transformed into incidence risk ratios (IRR). Among participants, 67.2% reported living near a blue space and 86.1% reported living near a green space. Racial/ethnic and socioeconomic disparities in access to blue and green spaces were observed, with less access among non-Hispanic Black participants and those with lower income and educational attainment. Living near blue (IRR = 1.23, 95% CI = 1.10, 1.39) or green space (IRR = 1.25, 95% CI = 1.02, 1.54) was significantly associated with more frequent weekly physical activity. Proximity to blue or green spaces is associated with more frequent physical activity during the COVID-19 pandemic. Health promotion efforts should include equitable strategies to improve accessibility to blue and green spaces.

Association Between Physical Activity and the Prevalence of Kidney Stones in American Adults: Results From a Multiyear National Survey

ObjectiveTo investigate the association between physical activity and the prevalence of kidney stones. MethodsA cross-section study was conducted using data from National Health and Nutrition Examination Survey 2007-2018. Physical activity was evaluated based on the Global Physical Activity Questionnaire. Multivariable logistic regression was performed to elucidate the association between physical activity (patterns, intensity, duration and frequency of moderate and vigorous physical activity) and the prevalence of kidney stones after adjusting for potential confounders. Stratified and interaction analyses were conducted to detect potential effect modifiers. In addition, physical activity was assessed using metabolic equivalent and physical volume, and followed the regression above. Water intake was obtained from the day 2 dietary recall and was included in the sensitivity analysis. ResultsA total of 34,390 participants were included in the analysis. The multivariable logistic regression revealed that individuals who engaged in moderate physical activity for 30-60 minutes per day had a significant inverse association with the prevalence of kidney stones in the fully-adjusted model (OR=0.804, 95%CI 0.700 to 0.923), while no more significant finding was observed for other physical activity parameters. Interaction and stratified analyses indicated no covariate modifying the association. The results above were robust in the sensitivity analysis. ConclusionThe duration of moderate physical activity (30-60 mins/day) is inversely associated with the prevalence of kidney stones, while no more significant association was observed between other physical activity parameters (including patterns, intensity, duration and frequency of vigorous physical activity, frequency of moderate physical activity) and kidney stones. Data availabilityData available in a publicly accessible repository that does not issue DOIs. Publicly available datasets were analyzed in this study. These data can be found here: https://www.cdc.gov/nchs/nhanes/index.htm.

The introduction of a minimum wage in Germany and the effects on physical activity participation

The relationship between income and physical activity has been extensively studied. This paper utilizes the introduction of the minimum wage in Germany in 2015 as a quasi-experiment to determine the causal effect of minimum wages on the frequency of physical activity participation. Employing survey data from the German Socio-Economic Panel between 2013 and 2017, regression-adjusted difference-in-difference models combined with matching techniques are estimated. Our findings reveal a notable negative effect immediately after the minimum wage implementation on physical activity frequency. Given that the introduction of the minimum wage did not increase monthly gross income but reduced working hours, it appears that affected individuals exhibit preferences and engage in utility maximization that do not emphasize healthy behaviors. This effect is particularly pronounced among older females in white-collar occupations.

The Association Between Physical Activity and Cognition in a Racially/Ethnically Diverse Cohort of Older Adults: Results From the Kaiser Healthy Aging and Diverse Life Experiences Study.

Most prior research on physical activity (PA) and cognition is based on predominantly white cohorts and focused on associations of PA with mean (average) cognition versus the distribution of cognition. Quantile regression offers a novel way to quantify how PA affects cognition across the entire distribution. The Kaiser Healthy Aging and Diverse Life Experiences study includes 30% white, 19% black, 25% Asian, and 26% Latinx adults age 65+ living in Northern California (n = 1600). The frequency of light or heavy PA was summarized as 2 continuous variables. Outcomes were z-scored executive function, semantic memory, and verbal episodic memory. We tested associations of PA with mean cognition using linear regression and used quantile regression to estimate the association of PA with the 10th-90th percentiles of cognitive scores. Higher levels of PA were associated with higher mean semantic memory (b = 0.10; 95% CI: 0.06, 0.14) and executive function (b = 0.05; 95% CI: 0.01, 0.09). Associations of PA across all 3 cognitive domains were stronger at low quantiles of cognition. PA is associated with cognition in this racially/ethnically diverse sample and may have larger benefits for individuals with low cognitive scores, who are most vulnerable to dementia.
