A Delphi Panel of People With Parkinson's Disease Regarding Responsibility: Toward a Preliminary Taxonomy.

IMPORTANCE: A sense of agency is associated with complex occupation-related responsibilities. A taxonomy can guide clinicians in enhancing responsibility in patients with Parkinson's disease (PwPD). OBJECTIVE: To (1) discover levels of responsibility in occupations for PwPD and (2) propose a taxonomy for occupations. DESIGN: A two-round Delphi study with PwPD and a one-round Delphi study with international experts. SETTING: Electronic survey. PARTICIPANTS: PwPD (N = 75) and international experts (N = 8). OUTCOMES AND MEASURES: PwPD expressed their levels of an inherent sense of responsibility for each occupation (1 = very low responsibility, 5 = very high responsibility). International experts rated their level of agreement (5 = strongly agree, 1 = strongly disagree) with each dimension of the taxonomy. A consensus was determined to have been reached if the interquartile range was ≤1 and 70% agreement in two adjacent categories was achieved. RESULTS: Thirty-three occupation categories were deemed as having very high to moderate responsibility for PwPD. Consequences of actions and the presence of others made up the two-dimensional responsibility taxonomy. Occupations have more challenging responsibility characteristics when they are performed with free choice, a level of high physical effort, alone, and with moral consequences. CONCLUSIONS AND RELEVANCE: This study yielded the first consensus among PwPD regarding responsibility in occupations as well as a classification system for charting the complexity of responsibility in occupations. The occupation list we have created can be beneficial to health care professionals when providing interventions or conducting outcome assessments. Plain-Language Summary: When planning interventions for patients with Parkinson's disease, it can be helpful for clinicians to be aware of patients' perspectives regarding their sense of responsibility to perform occupations. The use of a systematic sequence of challenging occupations with responsibility attributes ranging from less complex to more complex can help enhance patient occupational participation.

Factors associated with the Single Leg Squat test in female soccer players: a cross-sectional study.

BACKGROUND: The Single Leg Squat (SLS) test is widely used in the clinical setting to examine and evaluate rehabilitation goals. It is simple to perform and is proposed to have biomechanical and neuromuscular similarities to athletic movements. The aim of the present study was to investigate whether demographics, previous injuries, and biomechanical and psychosocial factors are associated with the outcome of the SLS, assessed as a total score for all segments and as a separate knee segment in elite and sub-elite female soccer players. METHODS: We conducted a cross-sectional study involving 254 female soccer players (22 yrs; SD ± 4, height 1.69 m; SD ± 0.1, weight 64 kg; SD ± 6) from divisions 1-3 of the Swedish Soccer League. During the preseason, we assessed the participants using the SLS and tested their hip strength and ankle mobility. Demographics, previous injury, sleep quality, fear of movement, anxiety, and perceived stress were assessed with questionnaires. Logistic regression models were built to analyse the association between the outcome of the SLS and the independent variables for the dominant and non-dominant leg. RESULTS: Significantly more participants failed the SLS on the dominant leg compared with the non-dominant leg (p < 0.001). The outcome of the SLS associated with various biopsychosocial factors depending on if the dominant or non-dominant leg was tested. The total score associated with hip strength for the dominant (OR 0.99, 95% CI 0.98-0.99, p = 0.04) and the non-dominant leg (OR 0.99, 95% CI 0.97-0.99, p = 0.03). The knee segment associated with division level for the dominant (div 2; OR 2.34, 95% CI 1.01-5.12, p = 0.033. div 3; OR 3.07, 95% CI 1.61-5.85, p = 0.001) and non-dominant leg (div 2; OR 3.30, 95% CI 1.33-8.00, p = 0.01. div 3; OR 3.05, 95% CI 1.44-6.43, p = 0.003). CONCLUSIONS: This study identified that leg dominance, division level, hip strength, and psychosocial factors were associated with the outcome of the SLS when assessed as a total score and as a separate knee segment. This indicates that clinicians need to understand that movement control is associated with factors from several domains. Whether these factors and, the results of the SLS are related to injury need to be studied prospectively. TRIAL REGISTRATION: Clinical Trials Gov, date of registration 2022-03-01.

Association between Weather and Self-Monitored Steps in Individuals with Prediabetes and Type 2 Diabetes in Sweden over Two Years.

BACKGROUND: Many studies have identified key factors affecting the rates of engagement in physical activity in older adults with chronic disease. Environmental conditions, such as weather variations, can present challenges for individuals with chronic diseases, such as type 2 diabetes when engaging in physical activity. However, few studies have investigated the influence of weather on daily steps in people with chronic diseases, especially those with prediabetes and type 2 diabetes. OBJECTIVE: This study investigated the association between weather variations and daily self-monitored step counts over two years among individuals with prediabetes and type 2 diabetes in Sweden. METHODS: The study is a secondary analysis using data from the Sophia Step Study, aimed at promoting physical activity among people with prediabetes and type 2 diabetes, which recruited participants from two urban primary care centers in Stockholm and one rural primary care center in southern Sweden over eight rounds. This study measured physical activity using step counters (Yamax Digiwalker SW200) and collected self-reported daily steps. Environmental factors such as daily average temperature, precipitation, and hours of sunshine were obtained from the Swedish Meteorological and Hydrological Institute. A robust linear mixed-effects model was applied as the analysis method. RESULTS: There was no association found between weather variations and the number of steps taken on a daily basis. The analysis indicated that only 10% of the variation in daily steps could be explained by the average temperature, precipitation, and sunshine hours after controlling for age, gender, and BMI. Conversely, individual factors explained approximately 38% of the variation in the observations. CONCLUSION: This study revealed that there was no association between weather conditions and the number of daily steps reported by individuals with prediabetes and type 2 diabetes taking part in a physical activity intervention over two years. Despite the weather conditions, women and younger people reported more steps than their male and older counterparts.

Impact of Menstrual cycle-based Periodized training on Aerobic performance, a Clinical Trial study protocol-the IMPACT study.

BACKGROUND: The menstrual cycle and its impact on training and performance are of growing interest. However, evidence is lacking whether periodized exercise based on the menstrual cycle is beneficial. The primary purpose of this proposed randomized, controlled trial, the IMPACT study, is to evaluate the effect of exercise periodization during different phases of the menstrual cycle, i.e., comparing follicular phase-based and luteal phase-based training with regular training during the menstrual cycle on physical performance in well-trained women. METHODS: Healthy, well-trained, eumenorrheic women between 18 and 35 years (n = 120) will be recruited and first assessed for physical performance during a run-in menstrual cycle at different cycle phases and then randomized to three different interventions: follicular phase-based training, luteal phase-based training, or regular training during three menstrual cycles. The training intervention will consist of high-intensity spinning classes followed by strength training. The menstrual cycle phases will be determined by serum hormone analysis throughout the intervention period. Assessment of aerobic performance (primary outcome) and muscle strength, body composition, and blood markers will be performed at baseline and at the end of the intervention. DISCUSSION: With a robust methodology, this study has the potential to provide evidence of the differential effects of exercise periodization during different phases of the menstrual cycle in female athletes.

Fear of movement was associated with sedentary behaviour 12 months after lumbar fusion surgery in patients with low back pain and degenerative disc disorder.

BACKGROUND: Movement behaviours, such as sedentary behaviour (SB) and moderate to vigorous physical activity (MVPA), are linked with multiple aspects of health and can be influenced by various pain-related psychological factors, such as fear of movement, pain catastrophising and self-efficacy for exercise. However, the relationships between these factors and postoperative SB and MVPA remain unclear in patients undergoing surgery for lumbar degenerative conditions. This study aimed to investigate the association between preoperative pain-related psychological factors and postoperative SB and MVPA in patients with low back pain (LBP) and degenerative disc disorder at 6 and 12 months after lumbar fusion surgery. METHODS: Secondary data were collected from 118 patients (63 women and 55 men; mean age 46 years) who underwent lumbar fusion surgery in a randomised controlled trial. SB and MVPA were measured using the triaxial accelerometer ActiGraph GT3X+. Fear of movement, pain catastrophising and self-efficacy for exercise served as predictors. The association between these factors and the relative time spent in SB and MVPA 6 and 12 months after surgery was analysed via linear regression models, adjusting for potential confounders. RESULTS: Preoperative fear of movement was significantly associated with relative time spent in SB at 6 and 12 months after surgery (ß = 0.013, 95% confidence interval = 0.004 to 0.022, p = 0.007). Neither pain catastrophising nor self-efficacy for exercise showed significant associations with relative time spent in SB and MVPA at these time points. CONCLUSIONS: Our study demonstrated that preoperative fear of movement was significantly associated with postoperative SB in patients with LBP and degenerative disc disorder. This finding underscores the potential benefits of preoperative screening for pain-related psychological factors, including fear of movement, preoperatively. Such screenings could aid in identifying patients who might benefit from targeted interventions to promote healthier postoperative movement behaviour and improved health outcomes.

Experiences of rehabilitation in young elite athletes: an interview study.

Even though injuries are common in elite youth sports, rehabilitation experiences are limited explored in young athletes. This study explored rehabilitation experiences in athletes with a previous injury studying at sports high schools. Twenty-six (14/12 females/males) young elite athletes (age 15-19 years) from 11 individual/team sports were interviewed in focus groups about the rehabilitation experiences following a sports injury. Data were analysed using content analysis. The results led to four main categories identified: 'High-quality rehabilitation', 'Lack of communication between healthcare and coach', 'Various consequences of injury' and 'No clear path to accessing rehabilitation'. The athletes valued that the healthcare providers had high expertise, were clear and signalled secureness and confidence. It was also important to receive help with rehabilitation as rapidly as possible. The athletes perceived that they felt responsible for providing information regarding rehabilitation progression between healthcare providers and their coach. It was also challenging not to be able to participate in training and competition while injured - causing a sense of frustration and fear of falling behind their peer athletes in terms of development and performance. The athletes described that no well-defined medical teams at the sports high schools were available- instead medical help was offered in several other ways. Based on our findings, the collaboration and communication between the healthcare providers and coaches need to be improved, addressing the rehabilitation content, progress and access to rehabilitation. Through these actions, the rehabilitation process will be more adjusted to the needs of young elite athletes.

Does injury risk increase when youth athletes start to study at a sports high school?

Background/aim: The injury risk is high in adolescent elite athletes. However, little is known about how the injury risk changes when young talented athletes start studying at a sports high school. The primary aim was therefore to explore the risk of injury when the athlete starts to study at a sports high school. A secondary aim was to identify risk factors for injury. Methods: A total of 489 athletes (age 15-16 years) were followed for 20 weeks, including 10 weeks before and 10 weeks after the athlete had started to study at a sports high school. Substantial injury was monitored in adolescent elite athletes using the Oslo Sports Trauma Research Centre Questionnaire. Results: The results showed that the mean difference (md) in injury prevalence was significantly (p=0.001) higher across the 10 weeks after school had started (md 3.6; 95% CI 1.5 to 5.8), compared with the 10 weeks before. Female athletes had significantly (p<0.001) higher injury prevalence (md 6.4%; 95% CI 3.0 to 9.8) across the 10 weeks after school had started, whereas male athletes (md 0.9%; 95% CI -1.8 to 3.6) had not (p=0.530). Three significant (p<0.05) risk factors were identified; previous injury within the past 12 months (OR 3.23), higher training volume (OR 0.97) and lower well-being (OR 0.71). Conclusions: Our results provide supporting evidence for increased injury risk in female adolescent elite athletes after the athletes had started to study at a sports high school.

Body Weight Satisfaction, Comments, Nutrition and Injury Risk in 489 Adolescent Elite Athletes.

Exposure to critical body weight comments in youth athletes could lead to decreased self-esteem, affect body image, and increase the risk of eating disorders and cause depressive symptoms. The aim was to explore differences between sex, body mass index, sports type, with regards to body weight satisfaction, exposure to critical body weight comments from their coach and nutrition status in adolescent elite athletes. A questionnaire about body weight, critical body weight comments and nutrition was distributed to 489 adolescent elite athletes and injury prevalence was monitored across 20 weeks. The results showed that almost one in four athletes (n=116, 24%) was not satisfied with their weight and 12% (n=59) had received critical body weight comments from their coach. Of the athletes who were unsatisfied with their body weight (n=116), 47% wanted to lose weight (n=55). A significant (p<0.05) higher proportion of ice hockey players and swimmers used nutritional supplements, were unsatisfied with their body weight, and were more exposed to critical body weight comments compared to athletes from other sports. Adolescent elite athletes as young as 15-16 years old are exposed to critical body weight comments from their coach and experience challenges with body weight satisfaction that is partly dependent on the sport-specific context.

A comparison of the effects of occupation-based interventions with and without responsibility feedback and conventional interventions on participation in people with idiopathic Parkinson's disease: study protocol for a randomized controlled trial.

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative disorder with debilitating motor and non-motor symptoms which affect participation in meaningful occupations. Occupation-based interventions can improve participation in people with PD. Evidence for incorporating structured and intensive occupational therapy by considering the concept of responsibility is lacking for this population. This trial will compare the effects of occupation-based interventions with and without responsibility feedback and conventional interventions on participation in people with idiopathic PD. METHODS: A total of 45 people with PD, between 35 and 85 years old and Hoehn and Yahr stages between I to III, will be recruited from movement disorder centers for this three-armed study. Participants will be randomized into three groups (occupation-based interventions with responsibility feedback, occupation-based interventions without responsibility feedback, and conventional interventions). All participants will receive intervention for 24 sessions during a period of 12 weeks (2 sessions per week). The primary outcome measure will be participation satisfaction. Participation frequency and restriction, self-perceived performance, performance satisfaction, motivation, volition, sense of agency, responsibility, physical activity, community integration, activities of daily living (ADL), instrumental ADL, upper extremity function, balance, fatigue, and quality of life will be measured as secondary outcome measures. All outcomes will be measured at baseline, session 9, session 17, post-intervention (week 13), and follow-up (week 25). DISCUSSION: This home-based high-intensity, structured, client-centered, and occupation-based intervention will be conducted by utilizing the concept of responsibility. This proposed trial may result in enhanced participation that would benefit other motor and non-motor symptoms in people living with PD. Findings from this proposed study are expected to expand the knowledge of clinicians and help them in evidence-based decision-making processes.

Coaches' experiences of injury prevention in youth elite athletes: An interview study of 10 coaches.

INTRODUCTION: Injury prevention is important to reduce the high injury risk in youth elite athletes studying at sports high schools. Coaches are considered important in youth elite sports and injury prevention. OBJECTIVES: The aim was to investigate perceptions and experiences of injury prevention among coaches at sports high schools. METHODS: A manifest qualitative content analysis with an inductive approach was used based on ten semi-structured interviews with coaches who work at sports high schools. RESULTS: An overarching theme "Coaches of youth athletes value injury prevention but have limited knowledge and support" was identified and five main categories were formed. Coaches perceived themselves to play an important role in injury prevention, yet they described limited time for knowledge acquisition and highlighted the close collaboration with other professions as a key in injury prevention. CONCLUSION: A coach's knowledge and support are critical factors in injury prevention of youth elite athletes. Evidence-based as well as non-evidence-based approaches are used, and the biopsychosocial perspective was not always taken into consideration. A need for more interprofessional collaboration and knowledge acquisition regarding injury prevention is warranted.

Consensus on Feedback Statements That Create Responsibility Among People With Parkinson's Disease: A Delphi Study.

IMPORTANCE: Sense of agency is associated with a sense of responsibility, which is essential to performing goal-directed occupations. OBJECTIVE: To reach consensus on a set of extrinsic feedback statements that have the potential to create a sense of responsibility among patients with neurological disorders in the course of performing daily or social occupations. DESIGN: Anonymous Delphi study with two rounds with international experts and one round with Irani patients with Parkinson's disease (PD). SETTING: Electronic survey. PARTICIPANTS: One hundred experts and 73 patients with idiopathic PD. OUTCOMES AND MEASURES: Experts and patients anonymously rated (5 = strongly agree/very effective, 4 = agree/effective, 3 = neither agree nor disagree/uncertain, 2 = disagree/ineffective, 1 = strongly disagree/very ineffective) their level of agreement with each survey statement and the effectiveness of each statement in creating a sense of responsibility in the course of performing daily or social occupations. Consensus was set as an interquartile range of ≤1 and ≥70% agreement in two adjacent categories of a Likert scale. RESULTS: In the experts' first round, consensus was reached on the level of agreement and effectiveness of 18 statements. In the second round, final consensus was achieved on all statements. In the one patient round, patients reached consensus on all statements. Finally, 34 statements were rated as 4 or 5 in terms of agreement and effectiveness, based on the opinions of experts and patients. CONCLUSIONS AND RELEVANCE: This study has produced a collection of feedback statements that might be useful in occupation-based interventions. What This Article Adds: Extrinsic responsibility feedback delivered while administering occupation-based interventions may increase volition, motivation, and engagement.

Occupations to Enhance Responsibility Among Patients With Parkinson's Disease: An International Delphi Study.

IMPORTANCE: The ability to perform voluntary actions is disrupted in Parkinson's disease (PD). Voluntary activities play a critical role in generating sense of agency, which underpins the concept of responsibility for people's daily occupations and their outcomes. According to this concept, the dearth of research regarding the concept of responsibility in rehabilitation hampers practitioners in delivering evidence-based care. OBJECTIVE: To generate a list of occupations that enhance an inherent sense of responsibility among people with PD that is based on consensus among experts. DESIGN: An anonymous and iterative Delphi study with two rounds. SETTING: Electronic survey. PARTICIPANTS: One hundred sixteen experts participated in the first round of the study, and 95 participated in the second round. OUTCOMES AND MEASURES: Panelists rated the level of inherent responsibility in each occupation and the importance of types of patient-related information on a 5-point Likert scale. Consensus was defined as reaching an interquartile range of >1. RESULTS: In the first round, consensus was reached on 19 occupations and all 38 types of patient-related information. Also, an additional 15 occupations and 16 types of patient-related information were added to the lists. Consensus was reached for all occupations and patient-related information presented in the second round. CONCLUSIONS AND RELEVANCE: Our results indicate that 61 occupations were deemed to enhance a moderate to a very high inherent sense of responsibility among people with PD. In addition, a wide range of patient-related information is considered very important or important while these occupation-focused interventions are delivered. What This Article Adds: Subjective knowledge of one's actions and their consequences lies behind people's daily occupations. Considering this knowledge when administering occupation-focused interventions can be beneficial for individuals with PD.

Previous Injury and Lower Well-being Increase Injury Risk in Female Adolescent Athletes.

Several risk factors for injury have been suggested in female elite athletes. However, there is a lack of prospective studies in young female athletes where multiple risk factors have been studied. The aim of this study was to identify risk factors for injury in female adolescent elite athletes. Substantial injuries were monitored in 222 athletes using the validated Oslo Sports Trauma Research Centre Questionnaire over 20 weeks. Over 20 potential risk factors were explored. Based on a binomial generalized linear mixed model, two significant (p<0.05) risk factors for injury were identified; previous injury within the last 12 months (OR 2.55) and well-being (OR 0.97). An athlete with a previous injury had twice as high a risk of injury (13% vs. 6%) compared to an athlete with no previous injury. Higher perceived well-being was associated with a decreased risk of injury. Based on a prospective design with a large sample of female adolescent elite athletes, investigating over 20 potential risk factors for injury, our results suggest that a previous injury and well-being are risk factors for injury.

Ankle-foot orthoses among children with cerebral palsy: a cross-sectional population-based register study of 8,928 children living in Northern Europe.

BACKGROUND: Cerebral palsy (CP) is an umbrella term where an injury to the immature brain affects muscle tone and motor control, posture, and at times, the ability to walk and stand. Orthoses can be used to improve or maintain function. Ankle-foot orthoses (AFOs) are the most frequently used orthoses in children with CP. However, how commonly AFOs are used by children and adolescents with CP is still unknown. The aims of this study were to investigate and describe the use of AFOs in children with CP in Sweden, Norway, Finland, Iceland, Scotland, and Denmark, and compare AFO use between countries and by gross motor function classification system (GMFCS) level, CP subtype, sex, and age. METHOD: Aggregated data on 8,928 participants in the national follow-up programs for CP for the respective countries were used. Finland does not have a national follow-up program for individuals with CP and therefore a study cohort was used instead. Use of AFOs were presented as percentages. Logistic regression models were used to compare the use of AFOs among countries adjusted for age, CP subtype, GMFCS level, and sex. RESULTS: The proportion of AFO use was highest in Scotland (57%; CI 54-59%) and lowest in Denmark (35%; CI 33-38%). After adjusting for GMFCS level, children in Denmark, Finland, and Iceland had statistically significantly lower odds of using AFOs whereas children in Norway and Scotland reported statistically significantly higher usage than Sweden. CONCLUSION: In this study, the use of AFOs in children with CP in countries with relatively similar healthcare systems, differed between countries, age, GMFCS level, and CP subtype. This indicates a lack of consensus as to which individuals benefit from using AFOs. Our findings present an important baseline for the future research and development of practical guidelines in terms of who stands to benefit from using AFOs.

Previous injury, sex and well-being are associated with injury profiles in 422 adolescent elite athletes of age 15-16 years: a 20-week longitudinal study.

Background: Adolescent elite athletes have a high injury risk and many risk factors for injury have been suggested. However, there is a lack of prospective studies in adolescent elite athletes of age 15-16 years. Aim: The aim of the study was to prospectively explore risk factors associated with different injury prevalence profiles in adolescent elite athletes. Methods: Substantial injury was monitored in adolescent elite athletes (n=422) using the validated Oslo Sports Trauma Research Center Questionnaire over 20 weeks. Athletes were categorised in tertiles based on injury prevalence. Results: The median substantial injury prevalence for all athletes was 10% (IQR 0%-20%). Compared with the 'no injury' group, previous injury (p<0.001, OR 3.91) and well-being (p<0.001, OR 0.93) were associated with the 'high injury' group, and previous injury (p=0.006, OR 1.96) and being a female athlete (p=0.002, OR 2.08) with the 'low injury' group. A female athlete with a previous injury and low perceived well-being (25th percentile) had a 48% risk (95% CI 36% to 59%) of belonging to the 'high injury' group, compared with 7% (95% CI 4% to 12%) for a male athlete with no previous injury and high well-being (75th percentile). Conclusion: Medical personnel should be aware of the high injury risk and risk factors for injury in adolescent elite athletes, and closely monitor the rehabilitation post-injury as a previous injury is such a strong risk factor for a new injury.

Is there a strong association between substantial injuries and previous injuries in adolescent elite athletes? A 1-year prospective cohort study.

INTRODUCTION: Adolescent elite athletes have a high injury risk and many risk factors for injury have been suggested, where the most conclusive risk factor is a previous injury. However, there is a lack of longitudinal data on a complete season in adolescent elite athletes. OBJECTIVES: The aim of the study was to explore the relationship between substantial injuries and previous injuries in adolescent elite athletes. A secondary aim was to explore sex differences in terms of this relationship. METHODS: Injury problems and substantial injury was monitored in adolescent elite athletes (n = 320) using the validated the Oslo Sports Trauma Research Center Questionnaire over 52 weeks. RESULTS: In total, 74% (n = 237) athletes reported at least one substantial injury during the study period. Previous injury problems were reported by 82% (n = 195), where 48% (n = 183) of all substantial injuries occurred within the same body location as a previous injury. Forty-four percent (n = 83) of the substantial injuries occurred within 2 weeks after occurrence of an injury problem. There was no association between sex and number of substantial injuries (p = .956, χ2 = 1.7). Poisson regression analysis demonstrated that 16-year-old athletes had a significantly (p = .034) increased risk of reporting substantial injuries (IRR 1.19, 95% CI: 1.01-1.39), compared to 18-year-old athletes. A high prevalence of substantial injuries occurred closely followed a previous injury in the same body location. CONCLUSION: Exploring rehabilitation following injuries in this age, addressing injury risk behavior when an injury problem has occurred and increasing awareness of the relationship between injury problems and substantial injuries are suggested to be important strategies to reduce substantial injuries in adolescent elite athletes.

Offered Support and Knowledge about the Menstrual Cycle in the Athletic Community: A Cross-Sectional Study of 1086 Female Athletes.

Many female athletes perceive that symptoms related to the menstrual cycle such as dysmenorrhea, premenstrual symptoms, amenorrhea or side-effects of hormonal contraceptives negatively impact their training, performance, and general well-being. Knowledge and communication about female athletes' health is therefore important in the sport community. The aims of this study were to explore the level of knowledge and communication about menstrual cycle issues and use of hormonal contraceptives in the athletic community and to describe the kinds of medical support offered to female athletes. A total of 1086 Swedish and Norwegian athletes from 57 different sports responded to a web-based questionnaire. Of these, 58% (n = 627) practiced team sports and 42% (n = 459) individual sports. Twenty-six percent (n = 278) of the athletes perceived their knowledge about female athlete health to be poor/very poor and the knowledge was most often acquired from medical staff. Fifty-three percent (n = 572) of the athletes perceived the knowledge acquired of their coaches as poor/very poor, even though a significantly (p < 0.001) higher proportion of athletes with a female coach (30%, n = 31) rated their coach's knowledge as very good/good, compared to athletes with a male coach (5%, n = 31). Only 11% (n = 116) of the athletes discussed female health issues with their coach. The majority (81%, n = 842) of the athletes partly to strongly agreed that female athlete health is considered a taboo topic in the athletic community. Forty-seven percent (n = 510) of the athletes had access to a physiotherapist, while only three percent (n = 29) had access to a gynecologist. Low perceived knowledge, lack of communication and support demonstrate the need for a multi-professional medical team and enhanced educational efforts focused on female athlete health in the athletic community.

Perceived impact of the menstrual cycle and hormonal contraceptives on physical exercise and performance in 1,086 athletes from 57 sports.

Female athletes train and compete under the potential influence of hormonal fluctuations during the menstrual cycle or during use of various hormonal contraceptives. Dysmenorrhea and premenstrual symptoms are common in the general population, as well as side effects of hormonal contraceptives. More detailed knowledge concerning prevalence and perceived impact of these symptoms on training and performance in different sports is required. The aim of the study was to 1) characterize perceptions of training and performance during the menstrual cycle phases and by hormonal contraceptive use in a large population of female athletes; 2) explore whether symptoms experienced are related to perceived performance; and 3) examine potential differences in these factors between athletes at different levels of performance. The study was based on self-reported data from 1,086 athletes from 57 sports at different performance levels via a web-based questionnaire. Thirty-seven percent (n = 407) of the athletes did not use hormonal contraceptives. In this group, menstrual cycle related symptoms were common across all athlete levels, particularly dysmenorrhea (74%, n = 300) and premenstrual symptoms (78%, n = 318), which also influenced perceived performance of aerobic fitness, muscle strength, mental sharpness, balance, and sleep quality. Sixty-three percent (n = 679) of the athletes used various hormonal contraceptives and 40% (n = 272) perceived a variety of side-effects. Physical performance was experienced equally independent of time-point of the pill-chart except for the period of inactive pills, which was associated with more negative impact. Nonetheless, only 18% (n = 191) of the athletes considered menstrual cycle or hormonal contraceptive issues when planning their training or competitions. These results indicate that greater focus is needed to identify and effectively treat different menstrual cycle and hormonal contraceptive related symptoms on an individual level.

Development and initial validation of a Swedish inventory to screen for symptoms of deficient perineum in women after vaginal childbirth: 'Karolinska Symptoms After Perineal Tear Inventory'.

BACKGROUND: Perineal tears are common after vaginal birth and may result in pelvic floor symptoms. However, there is no validated questionnaire that addresses long-term symptoms in women with a deficient perineum after vaginal birth. Thus, the objective of this study was to develop and psychometrically evaluate a clinical screening inventory that estimates subjective symptoms in women with a deficient perineum more than one year after vaginal delivery. MATERIAL AND METHODS: The development and psychometric evaluation employed both qualitative and quantitative methods. Qualitative strategies involved content validity and Think Aloud protocol for generation of items. The psychometric evaluation employed principal component analysis to reduce the number of items. The inventory was completed by women with persistent symptoms after perineal tears (N = 170). Results were compared to those of primiparous women giving birth by caesarean section (N = 54) and nulliparous women (N = 338). RESULTS: A preliminary 41-item inventory was developed, and the psychometric evaluation resulted in a final 11-item inventory. Women with confirmed deficient perineum after perineal trauma scored significantly higher on the symptoms inventory than women in control groups. A cut-off value of ≥ 8 could distinguish patients from controls with high sensitivity (100%) and specificity (87-91%). CONCLUSIONS: The Karolinska Symptoms After Perineal Tear Inventory, is a psychometrically valid 11-item patient-reported outcome measure for symptoms of deficient perineum more than one year after vaginal birth. More research is needed to validate the inventory in various patient populations as well as its use in pelvic floor interventions. The inventory has the potential to improve patient counseling and care in the future.

Physical Activity Patterns among Individuals with Prediabetes or Type 2 Diabetes across Two Years-A Longitudinal Latent Class Analysis.

BACKGROUND: This study aimed to identify distinct profiles of physical activity (PA) patterns among individuals with prediabetes or type 2 diabetes participating in a two-year PA trial and to investigate predictors of the profiles. METHODS: Data (n = 168, collected 2013-2020) from the cohort of a randomized trial aimed at increasing PA in individuals with prediabetes and type 2 diabetes were used. PA and sedentary behaviours were assessed by waist-worn ActiGraph GT1M accelerometers at baseline and at 6, 12, 18 and 24 months. Fifteen PA and sedentary variables were entered into a latent class mixed model for multivariate longitudinal outcomes. Multinominal regression analysis modelled profile membership based on baseline activity level, age, gender, BMI, disease status and group randomisation. RESULTS: Two profiles of PA patterns were identified: "Increased activity" (n = 37, 22%) included participants increasing time in PA and decreasing sedentary time. "No change in activity" (n = 131, 78%) included participants with no or minor changes. "Increased activity" were younger (p = 0.003) and more active at baseline (p = 0.011), compared to "No change in activity". No other predictor was associated with profile membership. CONCLUSIONS: A majority of participants maintained PA and sedentary patterns over two years despite being part of a PA intervention. Individuals improving PA patterns were younger and more active at baseline.
