Adherence to the Mediterranean Diet and its association with sustainable dietary behaviors, sociodemographic factors, and lifestyle: a cross-sectional study in US University students

BackgroundPromoting healthy and sustainable diets is increasingly important and the Mediterranean Diet (MD) has been recognized as an appropriate example that can be adapted to different countries. Considering that the college years are the time when US young adults are most likely to adopt unhealthy eating habits, the present study assessed adherence to the MD and the sustainability of dietary behaviors in a nationally representative sample of US university students, aiming to identify crucial levers for improving their eating behaviors.MethodsMD adherence and the adoption of healthy and sustainable dietary patterns were assessed through the KIDMED and the Sustainable-HEalthy-Diet (SHED Index questionnaires, respectively, administered through an online survey that also included sociodemographic and behavioral questions. Non-parametric and logistic regression analyses were performed.ResultsA sample of 1485 participants (median (IQR) age 21.0 (19.0–22.0); 59% women) correctly completed the survey. A medium adherence to the MD was the most prevalent (47%). According to multivariate logistic regression analysis, the likelihood of being more compliant with the MD increased when meeting physical activity recommendations, having a high SHED Index score, having the willingness to purchase and eat healthy and sustainable dishes, eating ultra-processed plant-based meat alternatives foods daily, and regularly attending the university canteen.ConclusionsEncouraging dietary patterns rich in plant-based foods and with a moderate intake of animal products is crucial to increasing the adoption of healthy and sustainable diets, and university dining services represent a suitable setting to build a supportive environment that educates students on human and planetary health.

Patient-reported treatment burden: comparison between vitamin-K antagonist and non-vitamin K antagonist oral anticoagulants

Abstract Introduction Treatment burden (TB) is defined as the overall workload that maintenance or improvement of their functioning and well-being poses on patients with chronic medical conditions. A high patient-reported TB has been associated with lower adherence to treatment and increased risk of major adverse events including death. We explored the differences in patient-reported TB value and prevalence of unacceptably high TB score (≥59 points) between patients receiving vitamin K antagonist oral anticoagulants (VKA) and non-vitamin K antagonist oral anticoagulants (NOAC). Furthermore, we explored contributory factors associated with TB and the relationship between TB and quality of life (QoL) in these patients. Methods A single-centre study included consecutive adult in- and outpatients on long-term oral anticoagulation, seen at a university clinical centre a from April to June 2019, who were willing to complete the Treatment Burden Questionnaire encompassing 13 items assessing the TB associated with taking medicine, self-monitoring, laboratory assessments, medical consultations, organisational and administrative requirements, adherence to dietary and physical activity recommendations, as well as the social repercussions of the treatment. Results Of 320 enroled patients, 206 (64.4%) were taking a VKA. Atrial fibrillation was the most common indication for long-term oral anticoagulation (n=299, 93.4%). The mean TB score was significantly higher in patients on VKA versus those taking a NOAC (48.8 ±26.5 vs. 41.8 ±19.7, P= 0.014), mostly owing to significantly higher TB values for questions related to self-monitoring, including the International Normalized Ratio (INR) control (3.85±3.32 vs. 1.62±1.38, P<0.001) and diet restrictions (3.98±3.43 vs. 2.48±2.49, P<0.001) in patients taking VKA (Figure 1). In addition, these patients significantly more often reported an unacceptably high TB of ≥59 points compared with those taking NOAC (30.1% vs 18.4%, P= 0.024). Multivariable regression analysis of predictors of TB in patients taking a VKA or NOAC are presented in Table 1. Conclusion In our study, patients receiving a VKA reported significantly higher TB compared to those using NOAC, especially regarding the questions about self-monitoring (including INR control) and diet restrictions. An unacceptably high TB was also more prevalent among patients receiving a VKA. Our findings suggest that prescribing NOACs in preference to VKAs could help in decreasing the self-reported TB in patients who need oral anticoagulant therapy.

Compliance with the 24-h Movement Guidelines for Portuguese children: differences between boys and girls

The 24-h Movement Guidelines for children recommend at least 60 min per day of moderate-to-vigorous intensity physical activity (PA), ≤ 2 h/day of screen time, and 9–11 h/day of sleep for children. Since little information is available on the 24-h Movement Guidelines in Portuguese children, this research attempts to know the proportion of Portuguese children meeting individual and combinations of these 24-h Movement Guidelines. Another aim of this study is to test sex differences in compliance with 24-h Movement Guidelines. A final sample of 1351 Portuguese children (51.4% girls, aged 7.65 ± 1.21) participated in this cross-sectional study. PA, screen time and sleep duration were parent-reported through a questionnaire. Only 3.7% of children met all three 24-h Movement Guidelines, whereas 11.9% met none. Although boys showed greater compliance with PA recommendations and girls with screen time recommendations, no significant sex differences were found in the compliance of all three 24-h Movement Guidelines. Given that 96.3% of Portuguese children did not meet 24-h Movement Guidelines, promoting these three movement behaviours in both boys and girls is crucial to encouraging positive consequences early.

#2892 The role of physical activity in onco-nephrology; a new weapon in the management of urological malignancies

Abstract Background and Aims New clinical evidence demonstrated that Physical Activity (PA) brings numerous benefits both at the level of Health-RelatedQuality of Life (HRQoL), biological mechanisms and at the psychological level. Indeed, it is well known that cancer treatments results in a series of symptoms and side effects that debilitates the patients with cancer and can be counteracted with physical activity. PA has an effect on several aspects of biological mechanisms: sex hormones, metabolic hormones, inflammation and adiposity, and immune function. Furthermore, strong evidence shows that aerobic or combined (aerobic and endurance) training reduces symptoms of anxiety, depression and fatigue. Combined training also leads to improvements in HRQoL, preventing and improving muscle loss and sarcopenia. This study aims to assess the influence of physical activity on this improved scenario. Method A consecutive cohort of 82 pts was enrolled in the Urological Department at San Raffaele Scientific Institute between 2018-2021. The control group (CT) was composed of 31 patients affected by CKD alone (GFR < 60 ml/min/1.73 m2, K-DIGO 2012 classification) and 51 patients with CKD and a recent history of urological malignancies (within 12 months) represented the case group (CS). Inclusion criteria were: Age (>18 years old), eGFR (<60 ml/min/1.73), Malnutritional Screening Tool (MST<2), Urological Cancer aggressiveness (no metastatic process), Informed consent (signed). Each patient underwent an initial nephrological and nutritional evaluation during which a conventional CKD Mediterranean-like diet with a controlled protein intake (MCPD) (0.6-1 g total protein/kg body weight/die and 30-35 kcal/kg body weight/die) was prescribed together with physical activity recommendation according to The National Kidney Foundation (NKF) for a period of 6 months (±2 months). Physical activity recommendations included some aerobic exercise for 30 min on most days of the week, plus other activities to increase muscle strength (exercises with resistance bands) e/o to improve flexibility (such as stretching) once or twice a week. To assess the influence of physical activity within the collaborative nephrologist-nutritionist approach (NNCA) on enhanced kidney function, the Rapid Assessment of Physical Activity (RAPA) test was administered to each patient. The test consists of two indicators: RAPA 1 will indicate aerobic physical activity levels (from 0=sedentary to 7=physically active), while RAPA 2 will indicate other types of exercises (0=none; 1=strength; 2=flexibility; 3=both). Subsequently, Bioelectrical Impedance Analysis (BIA) was conducted on all participants in the cohort to collect data on Body Cell Mass per height squared (BCM/h2), Phase Angle (PA), Extracellular Mass (ECM)/BCM, and Extracellular to Intracellular water ratio (ECW/ICW). Statistical analysis: Linear regression and Pearson's Chi-Squared test; Data analysis: R programming language and RStudio integrated development environment. Results Table 1 shows the patient's baseline characteristics. Table 2 shows anthropometric indices and parameters at pre- and post-dietary and nephrological intervention. Table 3 underlines the poor condition prevalent in CKD patients with or without oncological history, also confirmed by the low level of usual physical activity detected by the RAPA test at T0. Sure enough, our population was mainly inactive and sedentary. Results show that, after the intervention, our patients became regularly active (RAPA 1 score T0: 2.47; RAPA 1 score T1: 3.17; Delta = + 0.7, p < 0.0001); the same trend was observed for RAPA 2 score (observed increase 14%, p < 0.002). Conclusion Based on these findings, it can be inferred that standard clinical care should incorporate thorough assessment of both nutritional status and PA. The adoption of a MCPD, coupled with exercise training within a collaborative nephrologist-nutritionist approach, emerges as a potential strategy to enhance the HRQoL of this particular kind of patient.

Adherence to physical activity recommendations and associations with self-efficacy among Norwegian adolescents: trends from 2017 to 2021

BackgroundThe crucial role of physical activity (PA) in promoting well-being and overall health of adolescents is widely acknowledged. Previous global studies have consistently revealed low adherence to PA recommendations among adolescents, emphasizing potential links between PA engagement and self-efficacy in school-based populations. However, there is a need for further exploration of this relationship, in particularly gender differences and taking into account the potential influences of the COVID-19 pandemic. The objective of this study is to provide a comprehensive description of adherence to PA recommendations and its associations with self-efficacy in Norwegian school-based adolescents over the period from 2017 to 2021.MethodsCross-sectional data on physical activity (PA) levels and self-efficacy among 13–19-year-old Norwegian adolescents were collected from the Norwegian Ungdata Survey during the period 2017 to 2021. The survey, conducted in Norwegian lower- and upper-secondary schools, was administered electronically during school hours. All data collected is anonymous and has received approval from the Norwegian Agency for Shared Services in Education and Research (SIKT). Statistical analyses were performed using SPSS software.ResultsGirls consistently exhibited lower adherence to PA recommendations (17.6–19.8%) compared to boys (27.7–31.1%) each year from 2017 to 2021 (all p < 0.01). Similarly, girls reported lower self-efficacy (14.1 to 14.8 out of 20) than boys (15.5 to 15.9) during the same period (all p < 0.01). Regression analyses highlighted robust positive associations between PA and self-efficacy in those adhering to PA recommendations (i.e., physically active at least 5 times a week) and strong inverse associations for those reporting inactivity (never active) in both girls and boys from 2017 to 2021.ConclusionAdolescents in Norway report PA adherence ranging from 15 to 30%, with girls consistently exhibiting lower adherence to PA recommendations and reporting lower self-efficacy than boys. Notably, there are substantial associations between self-efficacy and both adherence to PA recommendations and inactivity over time. These findings underscore the significance of promoting adherence to PA recommendations during adolescence, especially among girls. Policymakers in Norway should focus on initiatives to increase PA levels among adolescents in both lower and upper secondary schools.

Enhancing Physical Activity Recommendations to Support Cognition in Homecare: A Quality Improvement Project

Background: Physical activity is a safe, evidence-based self-management strategy for older adults (aged 65+) with cognitive impairment. Although homecare occupational therapists (OTs) and physiotherapists (PTs) are well positioned to support the growing number of older adults living at home with cognitive impairment, physical activity is rarely recommended as a strategy to manage cognition. Objective: To increase OTs’ and PTs’ knowledge of physical activity recommendations, as well as increase the range of physical activity recommendations for older adults living at home with cognitive impairment. Methods: This quality improvement project used a pre-post intervention approach. Data was collected through a pre-post clinician survey and pre-post chart audit to evaluate the impact of a multimodal education intervention on OT and PT knowledge and practice. The intervention included educational sessions and the development of four client handouts. Results: Post-intervention, OT and PT survey results showed a non-significant improvement in knowledge, and a greater range of physical activity recommendations. The PT chart audit demonstrated a statistically significant increase in PTs providing education about the role of physical activity in relation to cognitive impairment. For OTs, there was a non-significant increase in physical activity recommendations. Conclusions: This multimodal education resulted in non-significant improvements in knowledge for OTs and PTs, however there were significant practice changes for PTs when providing education to patients about the impact of physical activity on cognition. Future research could refine the targeting of this intervention to better meet the needs of OTs and incorporate an evaluation of patient outcomes.

Level of sedentary lifestyle of workers in a higher education institution in Mexico

Currently, the workload and strict schedules lead employees to neglect their physical and mental health, which leads them to have a more sedentary life, which can become a risk factor for work-related diseases and mortality. The objective of this research is to determine the level of sedentary lifestyle by analyzing the variables associated with this behavior, in administrative and academic workers of a higher education institution in Mexico. The research followed a descriptive design and correlational, applying the Deming cycle methodology, for which information was collected through a direct survey and data analysis with a statistical program, on physical activity and sedentary lifestyle, in the in which a total of 108 respondents participated. A high prevalence of sedentary lifestyle was observed, present in 66.6% of the population studied and it was verified that 47,2% of the workers did not comply with the minimum recommendations for physical activity. The study revealed a high prevalence of sedentary behavior in workers. In addition, a dependency relationship of sedentary lifestyle with physical activity, gender and glucose levels was identified, these being the variables that explain this behavior in a significant way.

Implementing exercise recommendations into clinical practice—new findings from mental health professionals' and patients' perspectives in a university psychiatric setting

IntroductionTo date, concrete recommendations for physical activity in psychiatric treatments are limited. Thus, we evaluated knowledge, barriers and beliefs associated with exercise prescription of mental health professionals (MHP) to people with mental illnesses. We aimed to identify patients' barriers to exercise participation and to work out options addressing these barriers.MethodsIn our cross-sectional and questionnaire-based investigation, we recruited medical, nursing and therapeutic staff and patients of a psychiatric clinic by email and personal contact. Questionnaires contained the German versions of The Exercise in Mental Illness Questionnaire (EMIQ-G) and the International Physical Activity Questionnaires (IPAQ).ResultsWe included 100 MHP and 100 patients. MHP had significantly more knowledge regarding positive effects of exercise on general health than patients. Exercise was prescribed mostly (48.4%) or always (37.9%) by MHP. The data showed missing education in exercise prescriptions and different recommendation behavior. Male patients seemed to experience exercise more often as a positive distraction and had lower physical health barriers than females.DiscussionPhysical activity needs to be more integrated in psychiatric treatments. Some strategies as educating MHP and patients regarding potential benefits of exercise via psychoeducative brochures and adapting recommendations to individual symptoms could improve exercise behavior in psychiatric patients.

Determinants and Factors of Physical Activity After Oncology Treatments (DEFACTO) in Metropolitan France: Protocol of a Mixed Methods Study and Intervention.

While the scientific community widely recognizes the benefits of physical activity (PA) in oncology supportive care, cancer survivors who have undergone chemo- or radio-immunotherapy treatments struggle to meet PA recommendations. This underscores the importance of identifying factors influencing active lifestyle adoption and maintenance and proposing a multilevel model (micro-, meso-, and macrolevel) to better understand facilitators and barriers. Currently, no socioecological model explains an active lifestyle in the posttreatment phase of breast, colorectal, prostate, and lung cancers. The objective is to identify factors influencing an active lifestyle in cancer survivorship and assess the feasibility of an individualized program targeting an active lifestyle. The objectives will be addressed in 3 stages. Stage 1 aims to elucidate factors associated with the active lifestyle of cancer survivors. Stage 2 involves developing an explanatory model based on previously identified factors to create a tailored health education program for an active lifestyle after oncology treatments. Stage 3 aims to evaluate the feasibility and potential effects of this personalized health education program after its national implementation. First, the exploration of factors influencing PA (stage 1) will be based on a mixed methods approach, using an explanatory sequential design and multilevel analysis. The quantitative phase involves completing a questionnaire from a socioecological perspective. Subsequently, a subset of respondents will engage in semistructured interviews to aid in interpreting the quantitative results. This phase aims to construct a model of the factors influencing an active lifestyle and develop an individualized 12-week program based on our earlier findings (stage 2). In stage 3, we will implement our multicenter, multimodal program for 150 physically inactive and sedentary cancer survivors across metropolitan France. Program feasibility will be evaluated. Measured PA level by connected device and multidimensional variables such as declared PA and sedentary behaviors, PA readiness, motivation, PA preferences, PA knowledge and skills, and barriers and facilitators will be assessed before and during the program and 52 weeks afterward. The institutional review board approved the mixed methods study (phase 1) in April 2020, and the intervention (phase 3) was approved in March 2022. Recruitment and data collection commenced in April 2022, with intervention implementation concluded in May 2023. Data collection and full analysis are expected to be finalized by July 2024. The Determinants and Factors of Physical Activity After Oncology Treatments (DEFACTO) study seeks to enhance our understanding, within our socioecological model, of factors influencing an active lifestyle among cancer survivors and to assess whether a tailored intervention based on this model can support an active lifestyle.

Physical activity in students and its association with attention. A systematic review

Despite the recommendations for physical activity in children and adolescents, sedentary behaviors that may affect health are frequent in today's schools. Evidence suggests that physical activity has a beneficial effect on the development of attention, however, there is no clarity on the characteristics that physical activity should have to optimize the improvement of attention in schoolchildren. A search for articles in databases published between 2013 and 2023 was performed, and after applying the inclusion and exclusion criteria and after analyzing their results, thirty-three articles were identified. The results suggest that the practice of physical activity has a positive effect on attention, mainly selective attention, but it is not possible to establish the characteristics in relation to frequency, time, intensity, or type of exercise that yield the best results, probably due to the heterogeneity of the interventions and populations studied. More experimental studies are therefore required to help identify the characteristics of physical activity that best contribute to the development of attention as a cognitive indicator. Keywords: Attention, physical activity, school children, sedentary behaviors, cognitive indicators.

Motor competence and compliance with physical activity recommendations in Chilean schoolchildren

The development of motor competence is thought to be a crucial precursor to raising the trajectory of PA throughout a person’s life. The objectives of this study are to determine motor competence and the daily time of moderate and vigorous physical activity of students in 5th and 6th grade elementary in Chile, and to establish whether there are differences in motor competence according to sex and compliance with physical activity recommendations. 368 schoolchildren (M = 11.10 years; 54.3% girls) participated. To assess motor competence, the MOBAK 5–6 test was used. Physical activity was measured using ActiGraph wGT3X-BT® accelerometers. Boys (M = 3.65, SD = 2.14) showed better performance than girls (M = 2.39, SD = 1.80) in Object Control (p ≤ 0.001, PS = 0.67). For Self-Movement, the girls (M = 2.72, SD = 2.14) performed better than the boys (M = 2.40, SD = 1.86); however, there were no significant differences between the two sexes (p = 0.257). Boys (M = 48.4, SD = 22.8) presented more daily minutes of moderate and vigorous physical activity than girls (M = 35.9, SD = 16.9), with statistically significant differences (p ≤ 0.001, PS = 0.67). About MC according to compliance with the physical activity recommendations, only in Object Control there is a statistically significant difference (p ≤ 0.001; PS = 0.29) between the students who comply with the recommendations (M = 4.28, SD = 2.12) and those who do not achieve the recommended minutes (M = 2.67, SD = 1.29). By contrast, an analysis of Self-Movement found no significant difference (complies: M = 2.73, SD = 1.97; does not comply: M = 2.54, SD = 2.04; p = 0.408) between the two groups. It is necessary to generate instances that develop motor competence in all its dimensions to promote higher levels of moderate to vigorous physical activity.

Costs associated with insufficient physical activity in Germany: cross-sectional results from the baseline examination of the German national cohort (NAKO).

Insufficient physical activity (PA) is a leading risk factor for non-communicable diseases posing a significant economic burden to healthcare systems and societies. The study aimed to examine the differences in healthcare and indirect costs between sufficient and insufficient PA and the cost differences between PA intensity groups. The cross-sectional analysis was based on data from 157,648 participants in the baseline examination of the German National Cohort (NAKO) study. Healthcare and indirect costs were calculated based on self-reported information on health-related resource use and productivity losses. PA in the domains leisure, transport, and work was assessed by the Global Physical Activity Questionnaire and categorized into sufficient/insufficient and intensity levels (very low/low/medium/high) based on PA recommendations of the World Health Organization. Two-part models adjusted for relevant covariates were used to estimate mean costs for PA groups. Insufficiently active people had higher average annual healthcare costs (Δ €188, 95% CI [64, 311]) and healthcare plus indirect costs (Δ €482, 95% CI [262, 702]) compared to sufficiently active people. The difference was especially evident in the population aged 60 + years and when considering only leisure PA. An inverse association was observed between leisure PA and costs, whereas a direct association was found between PA at work and costs. Adjusting for the number of comorbidities reduced the differences between activity groups, but the trend persisted. The association between PA and costs differed in direction between PA domains. Future research may provide further insight into the temporal relationship between PA and costs.

Effects of Modifiable Activity-Related Health Behaviors on the Sleep-Pain Relationship in Adolescents.

Poor sleep and chronic pain are commonly related in adolescents. Only 5% of adolescents meet recommendations for physical activity and screen time, both of which impact the experience of sleep and pain disturbances. Research is needed to better understand the sleep-pain relationship in adolescents and to identify potential protective factors, such as activity-related health behaviors. This study examined sleep, behaviors that influence activity (i.e., physical activity, screen time), and their interaction as predictors of pain in a sleep-disordered sample of 105 adolescents aged 12-18 presenting for polysomnography. A hierarchical multiple linear regression was conducted to examine these relationships. Consistent with hypotheses, worse insomnia predicted worse pain. However, other activity-related health behaviors did not influence this relationship, ps > .05. Findings suggest that sleep should be the focus of treatment for adolescents with primary sleep disorders to prevent the onset or exacerbation of pain.

Uncovering physical activity trade-offs in transportation policy: A spatial agent-based model of Bogotá, Colombia

BackgroundTransportation policies can impact health outcomes while simultaneously promoting social equity and environmental sustainability. We developed an agent-based model (ABM) to simulate the impacts of fare subsidies and congestion taxes on commuter decision-making and travel patterns. We report effects on mode share, travel time and transport-related physical activity (PA), including the variability of effects by socioeconomic strata (SES), and the trade-offs that may need to be considered in the implementation of these policies in a context with high levels of necessity-based physical activity.MethodsThe ABM design was informed by local stakeholder engagement. The demographic and spatial characteristics of the in-silico city, and its residents, were informed by local surveys and empirical studies. We used ridership and travel time data from the 2019 Bogotá Household Travel Survey to calibrate and validate the model by SES. We then explored the impacts of fare subsidy and congestion tax policy scenarios.ResultsOur model reproduced commuting patterns observed in Bogotá, including substantial necessity-based walking for transportation. At the city-level, congestion taxes fractionally reduced car use, including among mid-to-high SES groups but not among low SES commuters. Neither travel times nor physical activity levels were impacted at the city level or by SES. Comparatively, fare subsidies promoted city-level public transportation (PT) ridership, particularly under a ‘free-fare’ scenario, largely through reductions in walking trips. ‘Free fare’ policies also led to a large reduction in very long walking times and an overall reduction in the commuting-based attainment of physical activity guidelines. Differential effects were observed by SES, with free fares promoting PT ridership primarily among low-and-middle SES groups. These shifts to PT reduced median walking times among all SES groups, particularly low-SES groups. Moreover, the proportion of low-to-mid SES commuters meeting weekly physical activity recommendations decreased under the 'freefare' policy, with no change observed among high-SES groups.ConclusionsTransport policies can differentially impact SES-level disparities in necessity-based walking and travel times. Understanding these impacts is critical in shaping transportation policies that balance the dual aims of reducing SES-level disparities in travel time (and time poverty) and the promotion of choice-based physical activity.

Exploring autonomous and controlled motivations for nature contact to maximise health benefits

Abstract Increasing evidence indicates contact with nature supports mental, physical and social health. However, beyond a widely reported number of barriers to nature contact, the constellation of motivations for human contact with nature is under‐theorised and under‐studied. We begin to develop indicators of autonomous and controlled motivations for nature contact informed by self‐determination theory. These include intrinsic motivation (i.e. enjoyment), integrated regulation (alignment with identify and life goals), identified regulation (a means to an end), introjected regulation (emotional reasons like guilt avoidance) and external regulation (such as peer pressure). We compare these motivation indices in a nationally representative sample of 5082 adults in Australia in 2022 with the Nature Relatedness Scale (NR6), and also test associations between them and five outcomes: time spent in nature, smartphone use in nature, interest in nature prescriptions, physical activity and self‐rated health. Statistical analyses were adjusted for potential confounding. Results demonstrate people have complex mixtures of motivations with varying potency for visiting natural settings and the extent to which those motives are autonomous or controlled matters for what they do, and the benefits accrued. For example, our analyses show that more direct considerations of intrinsic, integrated and identified forms of autonomous motivation have superior explanatory power than the NR6 for time spent in nature, interest in nature prescriptions, adherence to physical activity recommendations and self‐rated health. External regulations emphasising peer approval were associated not only with no additional time in nature but also with more distractive activities when in natural environments, as defined by more smartphone and social media use while there. While introjected regulations emphasising guilt avoidance were associated with increased nature contact, they were similarly associated with time spent on smartphones and social media when in natural environments, which has been shown to undermine restoration. Synthesis and applications: We need to formally measure autonomous and controlled motivations for nature contact to better understand both why some people visit natural environments, and whether they are mindfully maximising the health benefits of those experiences. This will help to inform robust nature‐based interventions that are acceptable, effective and sustainable for everyone. Read the free Plain Language Summary for this article on the Journal blog.

Advising activity-knowledge, attitudes, beliefs, and behaviors regarding the recommendation of physical activity in clinical psychologists.

Regular physical activity comes with multiple benefits for physical but also mental health and can be a pivotal element in the prevention and treatment of mental disorders. Clinical psychologists play an important role in supporting their patients in increasing physical activity levels. Up to date, there is only little research on recommendation of physical activity in psychologists worldwide and no such research for psychologists in Germany. Aim of this study was to assess knowledge, attitudes, beliefs and behaviors regarding physical activity in psychologists in Germany. We assessed knowledge, attitudes, beliefs and behaviors regarding physical activity among a sample of clinical psychologists in Germany using the "Exercise in Mental Illness Questionnaire-German" (EMIQ-G) in a cross-sectional online survey. 454 participants were included in the analysis. Participants reported moderate levels of knowledge and self-confidence in recommending physical activity. Only 14% of the participants received formal training regarding physical activity recommendation. Most participants recommended physical activity to their patients, primarily through personal discussions and referrals to exercise professionals. About one third did not give any recommendations regarding intensity. Strength training was only recommended by a minority. There is a need for greater integration of information and instructions regarding the recommendation of physical activity in the treatment of people with mental disorders in the training and further education of psychologists.

EXERCISE IS MEDICINE, BUT FOR WHAT? A MAPPING REVIEW OF PHYSICAL ACTIVITY RECOMMENDATIONS IN THE UK NICE CLINICAL GUIDELINES

INTRODUCTION & AIMS Clinical guidelines are used to inform best practice care, with research evidence a key aspect informing guideline recommendations. Physical activity is recommended for the management of a large variety of health conditions; however, the conditions that physical activity is recommended for has not been synthesised, nor has the quality of the evidence that informs these guideline recommendations. METHODS To understand the extent and type of evidence for physical activity recommendations across different health conditions in the UK National Institute for Health and Care Excellence (NICE) clinical guidelines. METHODS NICE was searched for clinical guidelines that recommended physical activity in the management/treatment of a health condition. Data relating to the condition, guideline date, physical activity recommendation(s) (general or specific), and evidence underpinning the recommendations was extracted. Where applicable, recommendations for research, priorities for implementation, and impact of the recommendations was also extracted. RESULTS 221 clinical guidelines were reviewed, of which 52 provided one or more physical activity recommendations and were included in the analysis. The guidelines covered a range of conditions including cardiovascular, mental health, metabolic, neurological, musculoskeletal, and others. Most guidelines (n=43) provided general physical activity recommendations (e.g. advice to be active) whereas only 9 provided specific recommendations (e.g. type and dose of physical activity). The evidence underpinning the physical activity recommendations in the guidelines was mixed but was mostly based on very low-moderate quality evidence. Despite this, few guidelines recommended further research around physical activity. CONCLUSION Physical activity is recommended in many clinical guidelines, demonstrating its perceived importance for improving health across a wide range of different conditions. The mostly low-quality evidence on which these recommendations are based questions why more guidelines do not recommend further high-quality research into physical activity. This would improve confidence in the evidence and hence confidence in the recommendations made by the guidelines.

PHYSICAL ACTIVITY RECOMMENDATIONS FOR PEOPLE WITH CHRONIC KIDNEY DISEASE: ARE RESEARCH PARTICIPANTS REPRESENTATIVE OF REAL-WORLD PATIENTS?

Physical activity is important to maintain good health for people with chronic kidney disease (CKD). However, people with CKD often have a complex health status which necessitates advice tailored to their safety profile. As such, this study aimed to review clinical practice recommendations on physical activity for people with CKD and evaluate how representative research participants are compared to a real-world cohort. A systematic search was completed to identify physical activity recommendations for people with CKD Stage 3-5. Primary studies that informed these recommendations were identified and data extracted. Meta-analysis of proportion was undertaken for sex, age, and comorbidities and compared to n=679 people with CKD from the Centre for Health Research Illawarra-Shoalhaven Population database. There were 17 physical activity recommendations for people with CKD. Thirteen provided physical activity guidelines for general adult populations. Three provided specific guidance on exercise prescription. Thirty-four primary studies informed these recommendations, including 22 intervention (65%); 6 aetiology (18%); 4 prognosis (12%); and 2 screening studies (6%). Twelve interventional studies were randomised controlled trials (55%). Primary intervention studies comprised 1,792 participants. Compared to the real-world cohort, research participants were significantly younger (mean age 59.7 vs 78.2); had higher proportions of male (60% vs 51%), hypertension (89% vs 80%) and peripheral vascular disease (12% vs 6%); but lower proportions of coronary artery disease (16% vs 20%) and diabetes (35% vs 38%). Physical activity recommendations for people with CKD lacked specific, tailored advice to address the complex health status and safety profile of people with CKD. Primary intervention studies that inform these recommendations included participants that were younger and had different comorbid profile when compared to a real-world cohort. Future intervention trials with pragmatic design are needed to improve the evidence base and specificity of recommendations.

The Impact of Removing the 10-Minute Bout Requirement and of Different Survey Administration Methods on National Physical Activity Estimates in Austria.

Monitoring survey methods, as well as movement recommendations, evolves over time. These changes can make trend observations over time difficult. The aim of this study was to examine the differences between 2 computer-assisted survey administration methods and the effect of the omission of the 10-minute minimum bout requirement in physical activity (PA) questions on PA outcomes. We used data from the second Austrian PA Surveillance System for 2998 adults (18-64y), applying computer-assisted personal interviewing and computer-assisted web interviewing. Within the computer-assisted web interviewing sample only, we added PA questions without the 10-minute requirement. Quantile and logistic regressions were applied. Between computer-assisted web interviewing and computer-assisted personal interviewing, within the computer-assisted personal interviewing sample, we found lower PA estimates in the leisure domain and work and household domain, but not in the travel domain, and no significant difference in the proportion of people meeting the PA recommendations. In all 3 PA domains, the median minutes did not differ when assessed with or without the 10-minute requirement. However, the percentage participation in the travel domain and work and household domain performing >0minutes per week PA was higher when there was no 10-minute requirement. The proportion of people meeting the Austrian aerobic recommendation for adults when computed with or without the 10-minute requirement did not differ. Our findings suggest that the omission of the 10-minute requirement does not seem to result in marked differences in PA estimates or the proportion of adults meeting the recommendations.

Digital Food Frequency Questionnaire Assessing Adherence to the Norwegian Food-Based Dietary Guidelines and Other National Lifestyle Recommendations: Instrument Validation Study.

Valid assessment tools are needed when investigating adherence to national dietary and lifestyle guidelines. The relative validity of the new digital food frequency questionnaire, the DIGIKOST-FFQ, against 7-day weighed food records and activity sensors was investigated. In total, 77 participants were included in the validation study and completed the DIGIKOST-FFQ and the weighed food record, and of these, 56 (73%) also used the activity sensors. The DIGIKOST-FFQ estimates the intake of foods according to the Norwegian food-based dietary guidelines (FBDGs) in addition to lifestyle factors. At the group level, the DIGIKOST-FFQ showed good validity in estimating intakes according to the Norwegian FBDG. The median differences were small and well below portion sizes for all foods except "water" (median difference 230 g/day). The DIGIKOST-FFQ was able to rank individual intakes for all foods (r=0.2-0.7). However, ranking estimates of vegetable intakes should be interpreted with caution. Between 69% and 88% of the participants were classified into the same or adjacent quartile for foods and between 71% and 82% for different activity intensities. The Bland-Altman plots showed acceptable agreements between DIGIKOST-FFQ and the reference methods. The absolute amount of time in "moderate to vigorous intensity" was underestimated with the DIGIKOST-FFQ. However, estimated time in "moderate to vigorous intensity," "vigorous intensity," and "sedentary time" showed acceptable correlations and good agreement between the methods. The DIGIKOST-FFQ was able to identify adherence to the Norwegian FBDG and physical activity recommendations. The DIGIKOST-FFQ gave valid estimates of dietary intakes and was able to identify individuals with different degrees of adherence to the Norwegian FBDG and physical activity recommendations. Moderate physical activity was underreported, water was overreported, and vegetables showed poor correlation, which are important to consider when interpreting the data. Good agreement was observed between the methods in estimating dietary intakes and time in "moderate to vigorous physical activity," "sedentary time," and "sleep."
