Cybersickness in People with Multiple Sclerosis Exposed to Immersive Virtual Reality.

Together with the wide range of possible benefits for the rehabilitation/training of people with multiple sclerosis (pwMS) and other neurologic conditions, exposure to immersive virtual reality (VR) has often been associated with unpleasant symptoms, such as transient dizziness, headache, nausea, disorientation and impaired postural control (i.e., cybersickness). Since these symptoms can significantly impact the safety and tolerability of the treatment, it appears important to correctly estimate their presence and magnitude. Given the existing data scarcity, this study aims to assess the existence and severity of possible adverse effects associated with exposure to immersive VR in a cohort of pwMS using both objective measurements of postural control effectiveness and subjective evaluations of perceived symptoms. To this aim, postural sway under upright quiet posture (in the presence and absence of visual input) of 56 pwMS with an Expanded Disability Status Scale score (EDSS) in the range of 0-6.5 (mean EDSS 2.3) and 33 unaffected individuals was measured before and after a 10-min immersive VR session and at 10 min follow-up on the basis of center of pressure (COP) trajectories. The severity of cybersickness symptoms associated with VR exposure was also self-rated by the participants using the Italian version of the Simulator Sickness Questionnaire (SSQ). Temporary impairments of postural control in terms of significantly increased sway area were observed after the VR session only in pwMS with mild-moderate disability (i.e., EDSS in the range of 2.5-6.5) in the presence of visual input. No changes were observed in pwMS with low disability (EDSS 0-2) and unaffected individuals. In contrast, when the visual input was removed, there was a decrease in sway area (pwMS with mild-moderate disability) and COP path length relating to the use of VR (pwMS with mild-moderate disability and unaffected individuals), thus suggesting a sort of "balance training effect". Even in this case, the baseline values were restored at follow-up. All participants, regardless of their status, experienced significant post-VR side effects, especially in terms of blurred vision and nausea. Taken together, the findings of the present study suggest that a short immersive VR session negatively (eyes open) and positively (eyes closed) impacts the postural control of pwMS and causes significant disorientation. However, such effects are of limited duration. While it is reasonable to state that immersive VR is sufficiently safe and tolerable to not be contraindicated in the rehabilitation/training of pwMS, in order to reduce possible negative effects and maximize the efficacy, safety and comfort of the treatment, it appears necessary to develop specific guidelines that consider important factors like individual susceptibility, maximum exposure time according to the specific features of the simulation, posture to adopt and protocols to assess objective and perceived effects on participants.

Breast/ovarian cancer genetic counseling: Do anxiety, depression, and health care-related fears influence cancer worry and risk perception?

BACKGROUND: The impact of family and personal cancer history and emotional factors, such as depression and anxiety, on disease representation has received limited attention in studies investigating the development of cancer-related worry and risk perception within the context of genetic counseling. The current study endeavors to fill this gap by exploring the extent to which depression and anxiety influence cancer worry and risk perception, and the role of health care-related fear as potential mediator in this relationship. METHODS: A sample of 178 women who underwent their first genetic counseling for breast/ovarian cancer, 52% of whom had previous cancer diagnoses, completed questionnaires assessing sociodemographic and clinical information, emotional distress in terms of anxiety and depression, cancer-related worry, risk perception, and health care-related fears. RESULTS: Results of mediation analyses showed that cancer-related worry and risk perception increased with rising levels of depression and anxiety, with health care-related fears acting as a mediator in the relationship of depression and anxiety with cancer worry and risk perception. Covariate analysis revealed that previous cancer diagnosis increases cancer-related worry but not risk perception, while the number of family members affected by cancer increases both outcomes. CONCLUSION: These findings emphasize the need for a holistic approach in genetic counseling and have implications for the clinical practice.

Comparison of Two Therapeutic Approaches of Cerebellar Transcranial Direct Current Stimulation in a Sardinian Family Affected by Spinocerebellar Ataxia 38: a Clinical and Computerized 3D Gait Analysis Study.

Spinocerebellar ataxia 38 (SCA 38) is a very rare autosomal dominant inherited disorder caused by a mutation in ELOV5 gene, specifically expressed in cerebellar Purkinje cells, encoding an enzyme involved in the synthesis of fatty acids. Seven symptomatic SCA 38 patients of a Sardinian family were administered 15 sessions of cerebellar anodal transcranial direct current stimulation (tDCS) in a cross-over study, employing deltoid cerebellar-only (C-tDCS) and cerebello-spinal (CS-tDCS) cathodal montage. Clinical evaluation was performed at baseline (T0), after 15 sessions of tDCS (T1) and after 1 month of follow-up (T2). Modified International Cooperative Ataxia Rating Scale (MICARS) and the Robertson dysarthria profile were used to rate ataxic and dysarthric symptoms, respectively. Alertness and split attention tests from Zimmermann test battery for attentional performance were employed to rate attentive functions. Moreover, 3D computerized gait analysis was employed to obtain a quantitative measure of efficacy of tDCS on motor symptoms. While clinical data showed that both CS and C-tDCS improved motor, dysarthric, and cognitive scores, the quantitative analysis of gait revealed significant improvement in spatio-temporal parameters only for C-tDCS treatment. Present findings, yet preliminary and limited by the small size of the tested sample, confirm the therapeutic potential of cerebellar tDCS in improving motor and cognitive symptoms in spinocerebellar ataxias and underline the need to obtain quantitative and objective measures to monitor the efficacy of a therapeutic treatment and to design tailored rehabilitative interventions. ClinicalTrials.gov identifier: NCT05951010.

Motor and cognitive skills implicated in the Motor Observation Questionnaire for Teachers (MOQ-T): A multidisciplinary approach.

This study was designed to determine the relationship between an observational measure of motor skills for teachers (i.e., MOQ-T), age, and some objectively assessed cognitive and motor indices. Two further goals were to examine which motor and cognitive factors predicted MOQ-T scores and to explore whether pupils with very low motor skills identified through MOQ-T also exhibited lower scores on objectively assessed motor and visuo-spatial tasks. A sample of 156 pupils aged 8.4 years-11.3 years and attending Italian primary school completed a battery of tests assessing writing speed, visuo-spatial abstract reasoning, fluency, and static balance abilities objectively assessed by measuring postural sway. Small to medium associations were found between MOQ-T scores and age, motor, and cognitive parameters, respectively. Moreover, approximately 26% of the variance in MOQ-T was predicted by sway area in the eyes-open condition, visuo-spatial fluency, and writing speed. Finally, pupils at risk of developmental coordination disorder exhibited poorer writing speed, and motor and higher-order visuo-spatial deficits. In conclusion, the synergistic use of objective measures of motor and cognitive functioning and observational screening questionnaires such as MOQ-T should be encouraged at school to identify pupils at risk of developmental coordination disorder.

Characterization of upper limb use in health care workers during regular shifts: A quantitative approach based on wrist-worn accelerometers.

Despite the high prevalence of upper limb (UL) work-related musculoskeletal disorders (WRMSD) among health care workers (HCWs), little is known about their relationship with exposure to biomechanical risk factors. This study aimed to assess UL activity features under actual working conditions using two wrist-worn accelerometers. Accelerometric data were processed to obtain duration, intensity, and asymmetry of UL use in 32 HCWs during the execution of commonly performed tasks (e.g., patient hygiene, transfer, and meal distribution) within a regular shift. The results show that such tasks are characterized by significantly different patterns of UL use, in particular, higher intensities and larger asymmetries were observed respectively for patient hygiene and meal distribution. The proposed approach appears, thus, suitable to discriminate tasks characterized by different UL motion patterns. Future studies could benefit from the integration of such measures with self-reported workers' perception to elucidate the relationship between dynamic UL movements and WRMSD.

Effects of a Mediterranean Diet Intervention on Maternal Stress, Well-Being, and Sleep Quality throughout Gestation-The IMPACT-BCN Trial.

Stress and anxiety are frequent occurrences among pregnant women. We aimed to evaluate the effects of a Mediterranean diet intervention during pregnancy on maternal stress, well-being, and sleep quality throughout gestation. In a randomized clinical trial, 1221 high-risk pregnant women were randomly allocated into three groups at 19-23 weeks' gestation: a Mediterranean diet intervention, a Mindfulness-Based Stress Reduction program, or usual care. All women who provided self-reported life-style questionnaires to measure their anxiety (State Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS)), well-being (WHO Five Well Being Index (WHO-5)), and sleep quality (Pittsburgh sleep quality index (PSQI)) at enrollment and at the end of the intervention (34-36 weeks) were included. In a random subgroup of 106 women, the levels of cortisol and related metabolites were also measured. At the end of the intervention (34-36 weeks), participants in the Mediterranean diet group had significantly lower perceived stress and anxiety scores (PSS mean (SE) 15.9 (0.4) vs. 17.0 (0.4), p = 0.035; STAI-anxiety mean (SE) 13.6 (0.4) vs. 15.8 (0.5), p = 0.004) and better sleep quality (PSQI mean 7.0 ± 0.2 SE vs. 7.9 ± 0.2 SE, p = 0.001) compared to usual care. As compared to usual care, women in the Mediterranean diet group also had a more significant increase in their 24 h urinary cortisone/cortisol ratio during gestation (mean 1.7 ± SE 0.1 vs. 1.3 ± SE 0.1, p < 0.001). A Mediterranean diet intervention during pregnancy is associated with a significant reduction in maternal anxiety and stress, and improvements in sleep quality throughout gestation.

An Immersive Virtual Kitchen Training System for People with Multiple Sclerosis: A Development and Validation Study.

Rehabilitation via virtual reality (VR) training tools allows repetitive, intensive, and task-specific practice in a controlled and safe environment. Our goal was to develop and validate a novel immersive VR system based on the practice of real-life activities in a kitchen environment in people with multiple sclerosis (pwMS) with upper-limb dysfunction. The novel immersive VR kitchen application includes several tasks, i.e., tidying up the kitchen, preparing a hamburger and soup meal, and dish washing. Following the development phase, the system was tested for an 8-week intervention period on a small sample of pwMS suffering from upper-limb dysfunction. The Suitability Evaluation Questionnaire for VR systems served as the primary outcome. The scores for enjoyment, sense of comfort with the system, feelings of success and control, realism, easy-to-understand instructions, assists in rehabilitation therapy, were between 4.0 and 4.6, indicating a high satisfaction. The scores for eye discomfort, dizziness, nausea, and disorientation during practice were between 2.8 and 1.3, indicating a low-to-moderate interference of the system. The virtual kitchen training system is feasible and safe for upper-limb training in pwMS and paves the way for future RCTs to examine the benefits of the system compared with standard care, thus improving the functionality of the upper limbs in pwMS.

Internalized homonegativity moderates the association between attachment avoidance and emotional intimacy among same-sex male couples.

Introduction: The present study aimed to examine dyadic associations between attachment insecurity and emotional intimacy in same-sex male couples, and to investigate whether and how each partner's internalized homonegativity (IH) moderated these associations. Methods: The sample included 138 same-sex male couples. Both dyad members completed self-report measures of attachment insecurity, emotional intimacy, and IH. The actor-partner interdependence model with moderation analysis was applied. Results: Indicated that higher levels of actor's and partner's attachment anxiety and attachment avoidance were associated with lower actor's emotional intimacy. IH moderated the partner effects of attachment avoidance on emotional intimacy. The partner's higher attachment avoidance was associated with one's own lower emotional intimacy at low (but not high) levels of one's own IH and at high (but not low) levels of the partner's IH. Discussion: Findings suggest that the partner's attachment avoidance may differently affect one's own emotional intimacy depending on the IH levels of both dyad members. Helping partnered sexual minority men decrease attachment insecurity while recognizing their own and their partners' IH may promote relationship quality.

Smoothness of Gait in Overweight (But Not Obese) Children Aged 6-10.

Excessive body mass represents a serious threat to the optimal psychophysical development of children, and it is known to be able to significantly affect their locomotor capabilities, making them more prone to the development of musculoskeletal disorders. However, despite the relevant number of existing studies, a clear gait pattern of overweight children has not been defined yet, particularly in the case of a mass excess that is relatively small (i.e., in those not obese). In the present study, we employed a wearable inertial measurement unit placed on the low back to derive spatio-temporal parameters and quantify the smoothness of gait (by means of harmonic ratio) from trunk accelerations acquired during gait trials carried out by 108 children aged 6-10 (46% males), stratified into two groups according to their body mass index (normal weight, n = 69 and overweight, n = 39). The results show that while gait speed, stride length, cadence and double support duration were found to be almost identical in the two groups, significant differences were observed in terms of harmonic ratio. In particular, overweight children exhibited a reduced harmonic ratio in the antero-posterior direction and higher harmonic ratio in the medio-lateral direction. While the significantly lower harmonic ratio in the antero-posterior direction is likely to be indicative of a loss of smoothness in the walking direction, probably due to a combination of factors associated with the altered movement biomechanics, the higher harmonic ratio in the medio-lateral direction might be associated with specific strategies adopted to increase lateral stability. Although further studies are necessary to elucidate the specific mechanisms that influence the smoothness of gait, it is noteworthy that harmonic ratios appear sensitive even to subtle change in locomotor control in overweight children characterized by apparently regular spatio-temporal parameters of gait and might be employed to assess the effectiveness of interventions designed to improve mobility functions.

Visibility as a Key Dimension to Better Health-Related Quality of Life and Mental Health: Results of the European Union Funded "ME-WE" Online Survey Study on Adolescent Young Carers in Switzerland.

This paper examines the health-related quality of life (HRQL) and mental health of adolescent young carers (AYCs) aged 15-17 in Switzerland, based on data collected within the Horizon 2020 project 'Psychosocial support for promoting mental health and well-being among AYCs in Europe' (ME-WE). It addresses the following questions: (1) Which characteristics of AYCs are associated with lower HRQL and with higher level of mental health problems? (2) Do AYCs who are less visible and less supported report a lower HRQL and more mental health issues than other AYCs? A total of 2343 young people in Switzerland, amongst them 240 AYCs, completed an online survey. The results show that female AYCs and AYCs with Swiss nationality more often reported having mental health issues than their male and non-Swiss counterparts. Furthermore, the findings show a significant association between receiving support for themselves and visibility from their school or employer and the HRQL. Moreover, AYCs who reported that their school or employer knew about the situation also reported fewer mental health issues. These findings can inform recommendations for policy and practice to develop measures aimed at raising the visibility of AYCs, which is the first step for planning AYC tailored support.

A Psychometric Study of the Perinatal Assessment of Maternal Affectivity (PAMA) for the Screening of Perinatal Affective Disorders in Mothers.

Recently, empirical evidence from perinatal studies has led researchers to pay more attention to fathers. The need to evaluate male suffering led at first to using the same screening tools developed for mothers. However, these instruments present validity concerns with fathers, and today the need to assume a gender-based perspective is clear. The Perinatal Assessment of Paternal Affectivity (PAPA) is a self-reported questionnaire for the screening of a variety of psychological and behavioral dimensions related to affectivity as experienced by fathers during the perinatal period. In the present study, the psychometric properties of the maternal version of the scale (Perinatal Assessment of Maternal Affectivity; PAMA) were examined. The study, based on 225 mothers and their partners (n = 215), used a cross-sectional design with a single assessment at the third trimester of pregnancy. Results indicated a one-factor structure for a seven-item version of the PAMA, which showed adequate internal consistency reliability and was associated in the expected direction with other clinically relevant variables (depression, psychological distress, perceived stress and dyadic adjustment). The findings suggest the usefulness of developing gender sensitive screening tools for the detection of perinatal affective disorders.

Recruitment of Adolescent Young Carers to a Psychosocial Support Intervention Study in Six European Countries: Lessons Learned from the ME-WE Project.

Young carers provide a substantial amount of care to family members and support to friends, yet their situation has not been actively addressed in research and policy in many European countries or indeed globally. Awareness of their situation by professionals and among children and young carers themselves remains low overall. Thus, young carers remain a largely hidden group within society. This study reports and analyses the recruitment process in a multi-centre intervention study offering psychosocial support to adolescent young carers (AYCs) aged 15-17 years. A cluster-randomised controlled trial was designed, with recruitment taking place in Italy, the Netherlands, Slovenia, Sweden, Switzerland and the United Kingdom exploiting various channels, including partnerships with schools, health and social services and carers organisations. In total, 478 AYCs were recruited and, after screening failures, withdrawals and initial dropouts, 217 were enrolled and started the intervention. Challenges encountered in reaching, recruiting and retaining AYCs included low levels of awareness among AYCs, a low willingness to participate in study activities, uncertainty about the prevalence of AYCs, a limited school capacity to support the recruitment; COVID-19 spreading in 2020-2021 and related restrictions. Based on this experience, recommendations are put forward for how to better engage AYCs in research.

A Serial Mediation Model of Insecure Attachment and Psychological Distress: The Role of Dispositional Shame and Shame-Coping Styles.

Shame is an intense, difficult to regulate, self-conscious emotion that predicts aspects of poor psychological functioning and is also strongly related to early relationships. Attachment insecurities, which constitute non-specific risk factors for psychological maladjustment, have been associated with an individual's tendency to experience shame. In this study, we sought to examine the serial mediating roles of dispositional shame and shame-coping styles (i.e., attack other, attack self, withdrawal and avoidance) in the association between anxious and avoidant attachment, and psychological distress. Using a cross-sectional design, self-reported data were collected. The study sample included 978 respondents (57% female) with a mean age of 32.17 ± 13.48 years. The results of the path analysis indicated that both attachment dimensions were sequentially associated with dispositional shame and then with the attack self shame-coping style, which was, in turn, positively related to psychological distress. Further, attachment insecurities were sequentially associated with dispositional shame and then with the avoidance shame-coping style, which was, in turn, negatively related to psychological distress. The model was gender invariant, suggesting that the serial mediation worked in a similar way for men and women. The practical implications of these findings are discussed.

Perceived Emotional Impact of COVID-19 and Depressive Symptoms among Male Same-Sex Chilean Couples: Direct and Indirect Dyadic Associations through Relationship Satisfaction.

Stressors arising from the COVID-19 pandemic can spill over into the quality of couple relationships, with negative consequences on mental health. The mental health impact of COVID-19 might be particularly pronounced in disadvantaged populations such as LGBT people. This study aimed to examine direct and indirect dyadic associations between emotional impact of COVID-19 and depressive symptoms through relationship satisfaction in male same-sex couples. Using a cross-sectional design, 158 male same-sex Chilean couples completed self-report measures of the emotional impact of COVID-19, relationship satisfaction and depressive symptoms. We used the actor-partner interdependence mediation model for indistinguishable dyads to explore the direct and indirect dyadic associations. Results indicated that each partner's perceived emotional impact of COVID-19 was associated with his own higher depressive symptoms directly and indirectly, through his own lower relationship satisfaction. The other partner's perceived emotional impact of COVID-19 was associated with one's own higher depressive symptoms only directly. Our findings reinforce the notion that satisfactory couple relationships can act as a protective factor against depression in the LGBT population. Programs to promote adaptive coping strategies to deal with the emotional impact of the COVID-19 pandemic may have beneficial effects for the emotional adjustment of male same-sex couples, also by promoting relationship satisfaction.

Green Trust as a Mediator in the Relationship between Green Advertising Skepticism, Environmental Knowledge, and Intention to Buy Green Food.

Changing individual habits towards greener choices is an essential ingredient in tackling the environmental crisis. Engaging in green behavior may improve psychological wellbeing. Although the intention to buy green products is widespread, the eco-friendly market is struggling to leave the ground. Greenwashing can increase skepticism towards green advertising, which in turn can hinder the intention to buy green products. Conversely, a better knowledge of environmental issues can promote a positive attitude towards environment and thus the intention to purchase green products. This study aimed to investigate if trust in green claims can mediate the relationships of green advertising skepticism and environmental knowledge with the intention to buy green food. An online survey was administered to 410 Italian consumers (63% female; 18-78 years). Our mediation model explained 23% of the variability in intention. Trust fully mediated the relationship between green advertising skepticism and intention to buy green food, while it partially mediated the relationship between perceived environmental knowledge and intention. Specifically, GAS was associated with lower INT through lower TR, whereas PEK was linked to higher INT though higher TR. The findings of this study can provide green market operators and policy makers with valuable information to encourage green food purchases.

Epidemiology of psoriasis in Italy: burden, cost, comorbidities and patients' satisfaction. A systematic review.

BACKGROUND AND AIM: The Italian data on psoriasis are partial and, in most cases, come from monocentric studies, not representative of the population. Our aim was to conduct a systematic review of the available evidence in order to get the overall picture of the Italian epidemiology (prevalence and incidence); burden of disease (direct and indirect costs, the impact on quality of life); comorbidities; and finally, the patients' satisfaction and acknowledgement of both the disease and the care services available. METHODS: This systematic review followed the guidelines of the Cochrane Collaboration and the Prepared Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020. The literature search was conducted on PubMed/Medline and Scopus. RESULTS: Out of 387 retrieved articles, 41 were included in the analysis. Psoriasis is a frequent condition in Italy: the prevalence is between 1,8% and 4,8% and the incidence is between 107,742 and 230,62 per 100.000 person-years. The most frequent comorbidities associated to psoriasis are: diabetes, hypertension, obesity, depression, cardiovascular diseases, hypertriglyceridemia, and hypercholesterolemia. The quality of life and severity of the disease are mostly affected by other concurrent diseases, early onset of the disease, low income, and low level of education. The costs of psoriasis were estimated between 500 euro and 15.000 euro depending on the disease's severity, the treatments used and hospitalization. CONCLUSIONS: In conclusion, psoriasis is a high-impact chronic disease. It is therefore fundamental to advocate a multidisciplinary approach to obtain a better health outcome, the patients' management and the cost savings could benefit from it.

Attachment and Dyadic Forgiveness in Individuals in Same-Sex Couple Relationships.

(1) Background: There is abundant evidence linking attachment insecurity to lower levels of interpersonal forgiveness. However, this association has been almost exclusively explored in people in a different-sex couple relationship, and there is little evidence referring to gay, lesbian, and bisexual (LGB) people in a same-sex relationship. The present study examines the association between romantic attachment and dyadic forgiveness in individuals involved in a same-sex couple relationship. (2) Methods: A total of 248 participants (52.8% female) aged 18-67 years (mean age: 31.02 ± 9.39) completed the Experiences in Close Relationships questionnaire and the Transgression-Related Interpersonal Motivation Inventory. (3) Results: Structural equation modeling showed that attachment avoidance was more strongly associated with dyadic forgiveness than attachment anxiety. Higher levels of attachment anxiety and avoidance were both linked to higher levels of avoidance motivation in response to partner transgressions, and higher attachment avoidance was linked to lower benevolence motivation. Multigroup analyses indicated a gender-specific association between attachment avoidance and revenge motivations, which was positive and significant among men only. (4) Conclusions: In the present study, we have identified that attachment avoidance plays a more prominent role in the tendency to forgive in same-sex couples. Implications at both theoretical and clinical practice levels are discussed.

Research and Innovation for and with Adolescent Young Carers to Influence Policy and Practice-The European Union Funded "ME-WE" Project.

Young carers are children and adolescents who provide care to other family members or friends, taking over responsibilities that are usually associated with adulthood. There is emerging but still scarce knowledge worldwide about the phenomenon of young carers and the impact of a caring role on their health, social and personal development spheres. This paper provides an overview of the main results from the ME-WE project, which is the first European research and innovation project dedicated to adolescent young carers (AYCs) (15-17 years). The project methods relied on three main activities: (1) a systematization of knowledge (by means of a survey to AYCs, country case studies, Delphi study, literature review); (2) the co-design, implementation and evaluation of a primary prevention intervention addressing AYCs' mental health (by means of Blended Learning Networks and a clinical trial in six European countries); (3) the implementation of knowledge translation actions for dissemination, awareness, advocacy and lobbying (by means of national and international stakeholder networks, as well as traditional and new media). Project results substantially contributed to a better understanding of AYCs' conditions, needs and preferences, defined tailored support intervention (resilient to COVID-19 related restrictions), and significant improvements in national and European policies for AYCs.

Association between Daily Pattern of Physical Activity and Depression: A Systematic Review.

Recent research suggested that daily pattern of physical activity (PA) may have an important association with depression, but findings are limited and contradictory. Our aim was to conduct a systematic review of the literature to summarize the literature evidence on the association between timing of PA and depression. A comprehensive search of PubMed/Medline and Scopus databases has been performed, and a total of five manuscripts have been thoroughly reviewed. The performed descriptive analysis shows lower levels of PA among individuals with depression or depressive symptoms, although evidence on the 24 h pattern of PA and depression is limited. An interesting finding is the association between lower PA during the morning, higher PA late in the evening (night), and depression or depressive symptoms. However, definitive conclusions could not be drawn due to the observational nature of the studies, their limited number, the high heterogeneity in the sample populations, and the studies' differing outcome definitions and exposure assessments. Future studies considering not only the level of PA but also its daily variability might be important to further explore this novel area of research.
