Current guidelines were supplemented by the latest evidence from systematic reviews and expert papers published between 2010 and 2020 on the prevention potential of food groups on chronic diseases such as type 2 diabetes, cardiovascular diseases and cancer. A diet score was developed by scoring the food groups according to a recommended low, moderate or high intake. The relative validity and reliability of the diet score, assessed by a food frequency questionnaire, was investigated. The consideration of current evidence resulted in 10 key food groups being preventive of the chronic diseases of interest. They served as components in the diet score and were scored from 0 to 1 point, depending on their recommended intake, resulting in a maximum of 10 points. Both the reliability (r = 0.53) and relative validity (r = 0.43) were deemed sufficient to consider the diet score as a stable construct in future investigations. This new diet score can be a promising tool to investigate dietary intake in etiological research by concentrating on 10 key dietary determinants with evidence-based prevention potential for chronic diseases.}, language = {en} } @article{AdnanSrsicVenticichetal.2020, author = {Adnan, Hassan Sami and Srsic, Amanda and Venticich, Pete Milos and Townend, David M.R.}, title = {Using AI for mental health analysis and prediction in school surveys}, series = {European journal of public health}, volume = {30}, journal = {European journal of public health}, publisher = {Oxford Univ.

Schools are a key setting for mental health promotion and illness prevention. One in five children and adolescents have a mental disorder, about half of mental disorders beginning before the age of 14. Beneficial and explainable artificial intelligence can replace current paper- based and online approaches to school mental health surveys. This can enhance data acquisition, interoperability, data driven analysis, trust and compliance. This paper presents a model for using chatbots for non-obtrusive data collection and supervised machine learning models for data analysis; and discusses ethical considerations pertaining to the use of these models. Methods: For data acquisition, the proposed model uses chatbots which interact with students. The conversation log acts as the source of raw data for the machine learning. Pre-processing of the data is automated by filtering for keywords and phrases. Existing survey results, obtained through current paper-based data collection methods, are evaluated by domain experts (health professionals). These can be used to create a test dataset to validate the machine learning models. Supervised learning can then be deployed to classify specific behaviour and mental health patterns. Results: We present a model that can be used to improve upon current paper-based data collection and manual data analysis methods. An open-source GitHub repository contains necessary tools and components of this model. Privacy is respected through rigorous observance of confidentiality and data protection requirements. Critical reflection on these ethics and law aspects is included in the project. Conclusions: This model strengthens mental health surveillance in schools. The same tools and components could be applied to other public health data. Future extensions of this model could also incorporate unsupervised learning to find clusters and patterns of unknown effects.}, language = {en} } @article{KuehneAyBrysonMarschneretal.2020, author = {K{\"u}hne, Franziska and Ay-Bryson, Destina Sevde and Marschner, Linda and Weck, Florian}, title = {The heterogeneous course of OCD}, series = {Psychiatry research : the official publication of the International Society for Neuroimaging in Psychiatry}, volume = {285}, journal = {Psychiatry research : the official publication of the International Society for Neuroimaging in Psychiatry}, publisher = {Elsevier}, address = {Clare}, issn = {0165-1781}, doi = {10.1016/j.psychres.2020.112821}, pages = {7}, year = {2020}, abstract = {Although effective treatments exist, obsessive-compulsive disorder (OCD) is, according to the views of patients and experts, still associated with chronicity, a term with no clear and consistent definition. To improve patient care and to foster research, a clear distinction between the various concepts of chronicity cited in the literature is crucial. The aim was thus to explicate central concepts related to courses and trajectories in OCD based on an explorative, scoping search of the existing literature. Our review revealed a considerable lack in content validity, as the concepts were operationalized inconsistently. Concepts related to symptom improvement were (complete) recovery, partial/full remission and partial/full response. Terms used in relation with symptom stability or worsening were chronic/continuous, intermittent and episodic course, waxing and waning, relapse, recurrence, deterioration and treatment-refractoriness. All concepts are explained and visualized as a result of the review. Further, based on authors' remarks, we present recommendations on how to enhance care for chronic OCD patients, namely training psychotherapists to apply CBT as intended, managing patient beliefs about disease and treatment, and adapting psychotherapy to OCD subtypes.

This cohort study describes the relationship between workload parameters and the occurrence of non-contact injuries, during weeks with high and low workload in professional soccer players throughout the season. Twenty-one professional soccer players aged 28.3 ± 3.9 yrs. who competed in the Iranian Persian Gulf Pro League participated in this 48-week study. The external load was monitored using global positioning system (GPS, GPSPORTS Systems Pty Ltd) and the type of injury was documented daily by the team's medical staff. Odds ratio (OR) and relative risk (RR) were calculated for non-contact injuries for high- and low-load weeks according to acute (AW), chronic (CW), acute to chronic workload ratio (ACWR), and AW variation (Δ-Acute) values. By using Poisson distribution, the interval between previous and new injuries were estimated. Overall, 12 non-contact injuries occurred during high load and 9 during low load weeks. Based on the variables ACWR and Δ-AW, there was a significantly increased risk of sustaining non-contact injuries (p < 0.05) during high-load weeks for ACWR (OR: 4.67), and Δ-AW (OR: 4.07). Finally, the expected time between injuries was significantly shorter in high load weeks for ACWR [1.25 vs. 3.33, rate ratio time (RRT)] and Δ-AW (1.33 vs. 3.45, RRT) respectively, compared to low load weeks. The risk of sustaining injuries was significantly larger during high workload weeks for ACWR, and Δ-AW compared with low workload weeks. The observed high OR in high load weeks indicate that there is a significant relationship between workload and occurrence of non-contact injuries. The predicted time to new injuries is shorter in high load weeks compared to low load weeks. Therefore, the frequency of injuries is higher during high load weeks for ACWR and Δ-AW. ACWR and Δ-AW appear to be good indicators for estimating the injury risk, and the time interval between injuries.}, language = {en} } @phdthesis{Deeken2022, author = {Deeken, Friederike}, title = {Relevance of non-pharmacological interventions that modify environmental factors in order to prevent and treat mental disorders in older patients and their caregivers}, school = {Universit{\"a}t Potsdam}, year = {2022}, abstract = {We live in an aging society. The change in demographic structures poses a number of challenges, including an increase in age-associated diseases. Delirium, dementia, and depression are considered to be of particular interest in the field of aging and mental health. A common theory regarding healthy aging and mental health is that the highest satisfaction and best performance is achieved when a person's abilities match the demands of their environment. In this context, the person's environment includes both the physical and the social environment. Based on this assumption, this dissertation focuses on the investigation of non-pharmacological interventions that modify environmental factors in order to facilitate the prevention and treatment of mental disorders in older patients and their caregivers. The first part of this dissertation consists of two publications and deals with the prevention of postoperative delirium in elderly patients. The PAWEL study investigated the use of a multimodal, non-pharmacological intervention in the routine care of patients aged 70 years or older undergoing elective surgery. The intervention included an interdepartmental delirium prevention team, daily use of seven manualized "best practice" procedures, structured staff training on delirium, and the adaptation of the hospital environment to the patients' needs. The second part of the dissertation used a meta-analysis to investigate whether technology-based interventions are a suitable form of support for informal caregivers of people with dementia. Subgroup analyses were conducted to examine the effect of different types of technology on caregiver burden and depressive symptoms. The following main results were found: The PAWEL study showed that the use of a multimodal, non-pharmacological intervention resulted in a significantly lower incidence rate of postoperative delirium and reduced days with delirium in the intervention group compared to the control group. However, this difference could not be observed in the group of patients undergoing elective cardiac surgery. The results of the meta-analysis showed that technology-based interventions offer a promising alternative to traditional "face-to-face" services. Significant effect sizes could be found in relation to both the burden and the depressive symptoms of caregiving relatives. These results provide further important information on the significant impact of non-pharmacological interventions that modify environmental factors on mental health, and support the consideration of such interventions in the prevention and treatment of mental disorders in both older patients and their caregivers.}, language = {en} } @article{MuellerEngelMuelleretal.2018, author = {Mueller, Steffen and Engel, Tilman and M{\"u}ller, Juliane and Stoll, Josefine and Baur, Heiner and Mayer, Frank}, title = {Sensorimotor exercises and enhanced trunk function}, series = {International journal of sports medicine}, volume = {39}, journal = {International journal of sports medicine}, number = {7}, publisher = {Thieme}, address = {Stuttgart}, issn = {0172-4622}, doi = {10.1055/a-0592-7286}, pages = {555 -- 563}, year = {2018}, abstract = {The aim of this study was to investigate the effect of a 6-week sensorimotor or resistance training on maximum trunk strength and response to sudden, high-intensity loading in athletes.

Objectives: We conducted an intervention study to investigate the effects of these nutritional factors on glucose and lipid metabolism, body-fat distribution, and liver fat content in subjects at increased risk of type 2 diabetes. Methods: This prospective, randomized, and controlled dietary intervention study was performed over 6 mo. All groups decreased their daily caloric intake by 400 kcal. The "control" group (N = 40) only had this requirement. The "no red meat" group (N = 48) in addition aimed to avoid the intake of red meat, and the "fiber" group (N = 44) increased intake of fibers to 40 g/d. Anthropometric parameters and frequently sampled oral glucose tolerance tests were performed before and after intervention. Body-fat mass and distribution, liver fat, and liver iron content were assessed by MRI and single voxel proton magnetic resonance spectroscopy. Results: Participants in all groups lost weight (mean 3.3 +/- 0.5 kg, P < 0.0001). Glucose tolerance and insulin sensitivity improved (P < 0.001), and body and visceral fat mass decreased in all groups (P < 0.001). These changes did not differ between groups. Liver fat content decreased significantly (P < 0.001) with no differences between the groups. The decrease in liver fat correlated with the decrease in ferritin during intervention (r(2) = 0.08, P = 0.0021). This association was confirmed in an independent lifestyle intervention study (Tuebingen Lifestyle Intervention Program, N = 229, P = 0.0084). Conclusions: Our data indicate that caloric restriction leads to a marked improvement in glucose metabolism and body-fat composition, including liver-fat content. The marked reduction in liver fat might be mediated via changes in ferritin levels. In the context of caloric restriction, there seems to be no additional beneficial impact of reduced red meat intake and increased fiber intake on the improvement in cardiometabolic risk parameters.

Methods: We collected data from 4074 PCPs including information on physician and practice characteristics, attitudes toward cardiovascular disease (CVD) prevention, and measures used during routine practice to prevent CVD. Here, we followed widely the established 5 A's strategy (Assess, Advise, Agree, Assist, Arrange). Results: The majority (87.2\%) of PCPs rated their own level of competence in PA counseling as 'high,' while 52.3\% rated their own capability to motivate patients to increase PA as 'not good.' Nine of ten PCPs routinely provided at least 1 measure of the modified 5 A's strategy, while 9.5\% routinely used all 5 intervention strategies. Conclusions: The positive attitude toward PA counseling among PCPs should be supported by other stakeholders in the field of prevention and health promotion. An example would be the reimbursement of health counseling services by compulsory health insurance, which would enable PCPs to invest more time in individualized health promotion.}, language = {en} } @article{LindenMuschallaHansmeieretal.2014, author = {Linden, Michael and Muschalla, Beate and Hansmeier, Thomas and Sandner, Gabriele}, title = {Reduction of sickness absence by an occupational health care management program focusing on self-efficacy and self-management}, series = {Work : a journal of prevention, assessment \& rehabilitation}, volume = {47}, journal = {Work : a journal of prevention, assessment \& rehabilitation}, number = {4}, publisher = {IOS Press}, address = {Amsterdam}, issn = {1051-9815}, doi = {10.3233/WOR-131616}, pages = {485 -- 489}, year = {2014}, abstract = {BACKGROUND: The aim of occupational health care management programs (OHMP) is to improve the health status of employees, increase work ability and reduce absence time.

OBJECTIVES: To study the effectiveness of an OHMP including special interventions to enhance self-efficacy and self-management. PARTICIPANTS: Employees from the German Federal Pension Agency. METHODS: Effects of an OHMP on sickness absence was studied by comparing an intervention group (N = 159) and two control groups (N = 450). A core feature of the OHMP were group sessions with all members of working teams, focussing on self-efficacy and self management of the individual participant as well as the team as a group (focus groups). Participants in the OHMP were asked for their subjective evaluation of the focus groups. Rates of sickness absence were taken from the routine data of the employer. RESULTS: Participants of the OHMP indicated that they had learned better ways of coping and communication and that they had generated intentions to make changes in their working situation. The rate of sickness absence in the intervention group decreased from 9.26\% in the year before the OHMP to 7.93\% in the year after the program, while there was in the same time an increase of 7.9\% and 10.7\% in the two control groups.

To achieve this aim, we informed teachers from eight schools in Germany about the definition of leaking and other warning signs and risk factors for school shootings in a one-hour information session. Teachers were then asked to report cases of leaking over a six- to nine-month period and to answer a questionnaire on leaking and its treatment after the information session and six to nine months later.
