Impact of antipsychotic medication on physical activity and physical fitness in adolescents: An exploratory study

The association between physical fitness and mental health among college students: a cross-sectional study

Introduction

Physical inactivity and mental health disorders are emerging threats to public health in China. Previous research on links between exercise and mental wellbeing have focused on clinical populations, with little evidence from the general population, particularly younger adults. We aimed to investigate associations between physical fitness and mental health in Chinese college students.

Methods

In this series, of cross-sectional observational studies, we enrolled 7,468 Chinese college students aged 16-24 years in 199 classes at Changzhou Vocational Institute of Engineering between Sept 1, 2017, and Jun 30, 2018. Exposures of interest were the students' physical fitness level, measured by the Chinese University Students Physique Test. The primary outcomes were mental health situations, measured by the University Personality Inventory (UPI). The multivariable linear regression models were used to assess the relationship between the levels of physical fitness and mental disorders symptoms.

Results

Completed mental health and physical fitness data were available for 6,724 participants aged 16-24 years. Compared with the failed group, the corresponding levels of difference in overall UPI scores were - 1.45 scores (95% CI: -2.45, -0.46; p < 0.01) for the passed group and - 2.95 scores (95% CI: -4.13, -1.77; p < 0.01) for the good group. Similar results were observed in the four different aspects of psychotic disorder symptoms.

Discussion

There was a significantly negative correlation between the level of physical fitness and phycological situations among Chinese college students. Our findings highlight the psychological situations of students with low physical fitness levels should be concerned.

We like to move it - patients with schizophrenia spectrum disorders are impaired in estimating their physical fitness levels and benefit from individualized exercise

BACKGROUND

People with schizophrenia spectrum disorders (SSD) engage less in physical activity than healthy individuals. The impact of subjectively assessed physical fitness levels on motivation for sports engagement and its relation to objective fitness parameters in SSD is unclear.

METHODS

25 patients with SSD (P-SSD) and 24 healthy controls (H-CON) participated in a randomized controlled study. Individual anaerobic thresholds (AT) were determined by an incremental exercise test and on separate days, aerobic exercise (cycling at 80% of workload at AT) and non-exercise control (sitting on an ergometer without cycling) sessions were performed. Demographic, clinical and objective physical fitness data (i.e., weekly physical activity, workload at AT, heart rate) were collected. Subjective physical fitness parameters were assessed before and after exercise and control sessions.

RESULTS

Weekly physical activity in P-SSD was lower than in H-CON (p < 0.05) attributed to reduced engagement in sport activities (p < 0.001). Workload and percentage of predicted maximal heart rate at AT were also reduced in P-SSD compared to H-CON (both p < 0.05). Although objective and subjective physical fitness parameters were related in H-CON (p < 0.01), this relationship was absent in P-SSD. However, during exercise sessions subjective physical fitness ratings increased to a stronger extent in P-SSD than H-CON (p < 0.05).

CONCLUSION

The missing relationship between subjective and objective physical fitness parameters in people with SSD may represent a barrier for stronger engagement in physical activity. Accordingly, supervised exercise interventions with individually adjusted workload intensity may support realistic subjective fitness estimations and enhance motivation for sports activity in individuals with SSD.

Association of the use of psychotropic drugs with hospitalization, cardiovascular events, and mortality in patients with type 2 diabetes: a propensity score-matched cohort study

Background

Use of psychotropic drugs (PD) may be associated with impairment of physical function. However, few studies have assessed the impact of PD on health outcomes in patients with type 2 diabetes. This study aimed to examine the associations between psychotropic drug use and handgrip strength (HGS) and between the use of PD and hospitalization in patients with type 2 diabetes.

Methods

From April 2013 to December 2015, we conducted a retrospective cohort study in patients with type 2 diabetes at the National Center for Global Health and Medicine Kohnodai Hospital. Patients aged 20 years and over who can measure HGS were included. All participants received nutritional guidance regarding diet therapy for type 2 diabetes at baseline. Nonpsychotropic drug users were matched one-to-one with the PD users using propensity score matching method with respect to their baseline covariates. The differences in HGS and the number of patients who had hospitalizations during the study period were examined. By Cox proportional hazard regression analysis, the association between the use of PD and repeated hospitalizations was estimated.

Results

A total of 1,282 patients were enrolled and followed up for 2.36 ± 0.73 years. In the propensity score matching cohort, HGS was significantly lower (p = 0.006) in PD users than non-PD users. PD users had more hospitalizations than non-PD users. Cox proportional hazard regression analysis confirmed the association of repeated hospitalizations with the use of PD (hazard ratio = 2.138; 95% confidence interval, 1.144-3.995, p = 0.017)). In addition, HGS was significantly and inversely correlated with the number of hospitalizations (r = -0.143, p = 0.013).

Conclusions

The use of PD could increase the risk of repeated hospitalizations. Skeletal muscle may play a role in reducing the risk of hospitalization in patients who are treated with PD.

Differences in body mass index trajectories of adolescent psychiatric inpatients by sex, age, diagnosis and medication: an exploratory longitudinal, mixed effects analysis

BACKGROUND

Adolescents in secure psychiatric care typically report high obesity rates. However, longitudinal research exploring the rate and extent of change is sparse. This study aimed to analyse sex differences in longitudinal body mass index (BMI) change for adolescents receiving treatment in a secure psychiatric hospital.

METHODS

The sample comprised 670 adolescents in secure psychiatric care. BMI trajectories from admission to 50 months of hospitalisation were produced using sex-stratified multilevel models. Systematic difference in mean BMI trajectories according to age at admission (14, 15, 16, or 17 years), medication (Olanzapine or Sodium Valproate), and primary diagnosis (Psychotic, non-Psychotic or Functional/behavioural disorders) were investigated.

RESULTS

Together, males and females experienced a mean BMI increase of 2.22 m/kg2 over the 50-month period. For females, BMI increased from 25.69 m/kg2 to 30.31 m/kg2 , and for males, reduced from 25.01 m/kg2 to 23.95 m/kg2 . From 30 to 50 months, a plateau was observed for females and a reduction in BMI observed for males. Psychotic disorders in males (β 3.87; CI 1.1-6.7) were associated with the greatest rate of BMI change. For medication, Olanzapine in females was associated with the greatest rate of change (β1.78; CI -.89-4.47).

CONCLUSIONS

This is the first longitudinal study exploring longitudinal BMI change for adolescent inpatients. Results highlight that individual differences in adolescent inpatients result in differing levels of risk to weight gain in secure care. Specifically, males with psychotic disorders and females taking Olanzapine present the greatest risk of weight gain. This has implications for the prioritisation of interventions for those most at risk of weight gain.

Patterns of antipsychotic prescription and accelerometer-based physical activity levels in people with schizophrenia spectrum disorders: a multicenter, prospective study

Antipsychotic polypharmacy (APP) in patients with schizophrenia spectrum disorders (SSDs) is usually not recommended, though it is very common in clinical practice. Both APP and SSDs have been linked to worse health outcomes and decreased levels of physical activity, which in turn is an important risk factor for cardiovascular diseases and premature mortality. This real-world, observational study aimed to investigate antipsychotic prescribing patterns and physical activity in residential patients and outpatients with SSDs. A total of 620 patients and 114 healthy controls were recruited in 37 centers across Italy. Each participant underwent a comprehensive sociodemographic and clinical evaluation. Physical activity was monitored for seven consecutive days through accelerometer-based biosensors. High rates of APP were found in all patients, with residential patients receiving more APP than outpatients, probably because of greater psychopathological severity. Physical activity was lower in patients compared to controls. However, patients on APP showed trends of reduced sedentariness and higher levels of light physical activity than those in monopharmacy. Rehabilitation efforts in psychiatric residential treatment facilities were likely to result in improved physical activity performances in residential patients. Our findings may have important public health implications, as they indicate the importance of reducing APP and encouraging physical activity.

Association between long-term hospitalization for mental illness and locomotive syndrome

BACKGROUND

Patients in psychiatric care wards face serious problems in terms of declining physical function due to aging and long-term hospitalization. This study aimed to determine the current status of locomotive syndrome (LS) in long-term inpatients in psychiatric care wards and to clarify the factors associated with LS risk severity.

METHODS

The study included 84 patients admitted to psychiatric care wards who underwent the LS stage test. We investigated the participants' age, length of stay, antipsychotic drug use, body mass index, and activities of daily living were assessed and analyzed the correlations between the LS stage test and each assessment item.

RESULTS

The participants' mean age was 60.0 ± 13.6 years, with those aged ≥60 years comprising nearly 60% of the sample. The participants' mean length of stay was 10.5 ± 12.0 years, and over half of the patients stayed >5 years: 17.9% stayed between 5 and 10 years, while 36.9% stayed ≥10 years. Nearly 90% of participants stayed for >1 year. The LS stage test showed that 60.7% of the participants were stage 3, 21.4% were stage 2, 14.3% were stage 1, and 3.6% had no risk. The results of the LS stage indicated significant correlations with age, length of stay, and the Barthel Index scores.

CONCLUSIONS

Patients who stay in a psychiatric care unit for a long period experience declining physical function, which is associated with aging and long-term hospitalization and might affect their activities of daily living.

Psychiatric medication and physical performance parameters - Are there implications for treatment?

INTRODUCTION

The impact of psychiatric medications and their enhancing or impairing effects on physical performance remains inconclusive. Therefore, with this systematic review we provide a comprehensive overview of frequently used psychotropic drugs and their effects on physical performance for the purpose of providing empirical information and deriving prescription and therapy recommendations for clinical practice.

METHODS

We systematically searched PubMed, PsycInfo, and Cochrane databases and extracted human studies investigating the effect of psychotropic drugs on parameters associated with the level of physical performance, such as exercise time, oxygen consumption, heart rate, muscle contraction or blood lactate concentration in physically healthy participants. 36 studies - comprising a broad range of psychotropic agents, such as antidepressants, antipsychotics, sedatives, and stimulants - were selected for final analyses.

RESULTS

Most studies (N = 32) were randomized controlled trials (RCT) with a double-blind crossover design. Antidepressants (N = 21) were the most frequently studied drug class, with contradictory results e.g., performance enhancement in warm environment but not in temperate conditions for bupropion or inconsistent findings between studies for other antidepressants. Antipsychotics (N = 3) mainly showed impairing effects on physical performance, while stimulants (N = 4) were often performance-enhancing. Sedatives (N = 9) may cause a hangover effect.

CONCLUSION

The examined studies with heterogeneous design showed different effects of psychiatric medications on physical performance. Antipsychotics seemed to be performance impairing, while the findings for antidepressants and sedatives were more inconsistent. Stimulants were the only group with consistent performance-enhancing effects. However, most studies were conducted with a small sample size (N < 10), mostly in well-trained subjects rather than in patients with psychiatric disorders, and most studies used single-dose designs. These issues impede the formulation of generalized conclusions for treatment regimes and should therefore be considered in further longitudinal studies for clinically reliable statements. Nevertheless, answering our research question is quite relevant for clinical practice and therapeutic prescription and should be further investigated especially considering the high drop-out rates in drug treatment.

Dysregulated inflammation may predispose patients with serious mental illnesses to severe COVID‑19 (Review)

Genetic and nongenetic factors associated with an increased inflammatory response may mediate a link between severe coronavirus disease 2019 (COVID‑19) and serious mental illness (SMI). However, systematic assessment of inflammatory response‑related factors associated with SMI that could influence COVID‑19 outcomes is lacking. In the present review, dietary patterns, smoking and the use of psychotropic medications are discussed as potential extrinsic risk factors and angiotensin‑converting enzyme (ACE) insertion/deletion (I/D) gene polymorphisms are considered as potential intrinsic risk factors. A genetics‑based prediction model for SMI using ACE‑I/D genotyping is also proposed for use in patients experiencing severe COVID‑19. Furthermore, the literature suggests that ACE inhibitors may have protective effects against SMI or severe COVID‑19, which is often linked to hypertension and other cardiovascular comorbidities. For this reason, we hypothesize that using these medications to treat patients with severe COVID‑19 might yield improved outcomes, including in the context of SMI associated with COVID‑19.

Physical activity as an intervention in severe mental illness

Physical activity is a modifiable risk factor for several physical and mental health conditions. It is well established that people with severe mental illness have increased risk of physical health complications, particularly cardiovascular disease. They are also more likely to be physically inactive, contributing to the elevated cardiovascular and metabolic risks, which are further compounded by antipsychotic medication use. Interventions involving physical activity are a relatively low risk and accessible way of reducing physical health problems and weight in people with severe mental illness. They also have wider benefits for mental health symptoms and quality of life. However, many barriers still exist to the widespread implementation of physical activity interventions in the treatment of severe mental illness. A more concerted effort is needed to facilitate their translation into routine practice and to increase adherence to activity interventions.

Reliability and validity of physical fitness tests in people with mental disorders: A systematic review and meta-analysis

BACKGROUND

Several tests are available to assess the different components of physical fitness, including cardiorespiratory fitness, muscular strength, and flexibility. However, the reliability and validity of physical fitness tests in people with mental disorders has not been meta-analyzed.

AIMS

To examine the reliability, concurrent, and convergent validity of physical fitness tests in people with mental disorders.

METHODS

Studies evaluating the reliability, concurrent, and convergent validity of physical fitness tests in people with mental disorders were searched from major databases until January 20, 2020. Random-effects meta-analyses were performed pooling (1) reliability: test-retest correlations at two-time points, (2) convergent validity between submaximal tests and maximal protocols, or (3) concurrent validity between two submaximal tests. Associations are presented using r values and 95% confidence intervals. Methodological quality was assessed using the Quality Appraisal of Reliability Studies and the Critical Appraisal Tool.

RESULTS

A total of 11 studies (N = 504; 34% females) were included. Reliability of the fitness tests, produced r values ranging from moderate (balance test-EUROFIT; [r = 0.75 (0.60-0.85); p = 0.0001]) to very strong (explosive leg power EUROFIT; [r = 0.96 (0.93-0.97); p = 0.0001]). Convergent validity between the 6-min walk test (6MWT) and submaximal cardiorespiratory tests was moderate (0.57 [0.26-0.77]; p = 0.0001). Concurrent validity between the 2-min walk test and 6MWT (r = 0.86 [0.39-0.97]; p = 0.0004) was strong.

CONCLUSION

The present study demonstrates that physical fitness tests are reliable and valid in people with mental disorders.

Clinical determinants of physical activity and sedentary behaviour in individuals with schizophrenia

INTRODUCTION

Modifiable lifestyle factors such as physical activity (PA) have ameliorative effects on commonly reported health conditions in schizophrenia like cardiovascular diseases and diabetes. Similarly, reduction in sedentary behaviour (SB) promotes better physical health. However, engaging individuals with schizophrenia in PA and less SB can be challenging because of symptoms of schizophrenia. The aims of the present study are (i) to examine the profiles of PA and SB in individuals with schizophrenia; and (ii) to identify their respective clinical determinants.

METHOD

157 individuals with schizophrenia were recruited. PA and SB were examined via the Global Physical Activity Questionnaire (GPAQ). Psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS). Potential clinical predictors of PA and SB were identified via univariate regression analyses and subsequently included in the final multiple regression models for PA and SB respectively.

RESULTS

63.7% met the WHO PA guidelines. Work-related activity was the largest domain specific contribution towards PA. Mean duration of SB was approximately 9 h and about 57.3% reported at least 8 h or more of SB daily. Positive symptom was associated with engagement in PA and reduced duration of SB. Negative symptom was associated with greater SB.

CONCLUSION

With emerging evidence of deleterious health effects of SB independent of PA, it is important to monitor SB in individuals with schizophrenia, particularly those presenting with negative symptoms. While the lack of treatment response for negative symptoms remains a challenge, effort should be made to reduce duration of SB.

A Qualitative Examination of the Physical Activity Needs of People with Severe Mental Illness

It is recognised that physical activity has a positive impact on quality of life, social well-being and overall health of people with severe mental illness. However, there is a lack of theory informed programmes that support people with mental illness to adopt regular physical activity behaviour. The aim of this case study was to identify determinants of long-term physical activity among people with severe mental illness that may then inform the development of more suitable physical activity programmes. Semi-structured interviews were conducted with 15 people (13 men and 2 women) with a mean age of 36.7 [standard deviation (SD)=11.8] who had a diagnosed mental illness and were attending a physical activity programme run by a mental health non-governmental organisation. Interview data was analysed using the documentary method to emphasise the perspective of people with severe mental illness. Three participation types were generated in the context of individuals' physical activity orientation and social background-first 'rehabilitative orientated' (physical activity as a supportive measure to re-enter the labour market and develop a daily routine); second 'social-orientated' (social well-being within the group as the primary motive); finally, 'trust-orientated' (a sense of trust that encourages participation). Based on these type-specific categories, it is suggested that different settings (mental health care centres and sport clubs) might be needed to attract and maintain the physical activity engagement of people with severe mental illness. In the context of sport clubs, it is recommended that coaches undergo training in mental health literacy.

Considerations in the Care of Athletes With Attention Deficit Hyperactivity Disorder

OBJECTIVES

Uncover literature pertaining to: (1) attention deficit hyperactivity disorder (ADHD) and how it impacts athletes; (2) ADHD medication effects; (3) regulations regarding ADHD medications; (4) approaches to conditions similar to, and occurring with, ADHD; and (5) use of stimulants.

DATA SOURCES

MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews, Ovid interface.

MAIN RESULTS

ADHD can have many effects on athletes and sports participation. Exercise has positive benefits on ADHD behaviors and players' attitudes. Athletes with ADHD can have worsened ADHD symptoms after concussions. Attention deficit hyperactivity disorder is a modifier of return to play; baseline ADHD symptoms should be used to guide management. Management should include medications, behavioral/psychosocial therapy, and academic accommodations. Behavioral therapy combined with medication is superior to behavioral treatment alone. Sustained exercise as ADHD treatment should be considered mainstay in management. Sports can increase thermogenic effects of stimulants, heat injury, and cardiac arrhythmias. Increased aggressiveness, improved pain tolerance, and decreased sense of fatigue are some attributes of stimulants that are presumed to impart some advantage to athletes, but evidence is uncertain. Attention deficit hyperactivity disorder medications may lead to myocardial infarctions, cerebrovascular accidents, paranoid psychoses, seizures, insomnia, tremors, anxiety, hypertension, and death.

CONCLUSIONS

Athletes' performance and quality of life can be negatively affected by ADHD. Risks exist for those who take ADHD medications. More research is needed on the implications ADHD may have in specific sports, and on possible advantages of medication use. Potential deleterious effects of these medications should be addressed.

Antipsychotics Promote Metabolic Disorders Disrupting Cellular Lipid Metabolism and Trafficking

Antipsychotics frequently cause obesity and related metabolic disorders that current psychopharmacological/endocrinological theories do not explain consistently. An integrative/alternative theory implies metabolic alterations happening at the cellular level. Many observations in vitro and in vivo, and pivotal observations in humans, point towards chemical properties of antipsychotics, independent of receptor binding characteristics. Being amphiphilic weak bases, antipsychotics can disrupt lysosomal function, affecting cholesterol trafficking; moreover, by chemical mimicry, antipsychotics can inhibit cholesterol biosynthesis. These two molecular adverse effects may trigger a cascade of transcriptional and biochemical events, ultimately reducing available cholesterol while increasing cholesterol precursors and fatty acids. The macroscopic manifestation of these molecular alterations includes decreased high-density lipoprotein and increased very low-density lipoprotein and triglycerides that may translate into obesity and related metabolic disorders.

Medication and physical activity and physical fitness in severe mental illness

Anti-psychotic medication has emerged as the primary medical treatment for people with severe mental illness, despite the great risks involved in the use of this medication. In addition, this population suffers from problems of obesity, sedentary lifestyle and poor physical fitness, which is aggravated by the use of this type of medication. The objective of this study is to explore the influence of the most commonly used antipsychotics in this population (Olanzapine and Risperidone) on physical activity and the physical fitness of people with severe mental illness. Sixty-two people between 26 and 61 years of age with severe mental illness were assessed. All participants were evaluated with a battery of 11 physical tests to assess their physical fitness and with the IPAQ-short version questionnaire to determine their level of physical activity. The doses of Risperidone and Olanzapine were also evaluated in all participants. Significant differences were found for physical activity, with higher levels reported in those patients with severe mental illness who did not take any of these medications. Regarding physical fitness, significant differences were only found for the consumption of Risperidone, with better physical fitness levels seen in patients who did not consume this medication; on the other hand, for the consumption of Olanzapine, differences were found in muscular strength, balance and aerobic condition with better values in non-Olanzapine consumers compared with Olanzapine consumers.

Physical Activity of Patients with Chronic Schizophrenia and Related Clinical Factors

OBJECTIVE

This study aimed to investigate clinical factors contributing to the low physical activity (PA) of patients with chronic schizophrenia.

METHODS

PA was measured in 50 outpatients with chronic schizophrenia using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Psychopathology, psychosocial functioning, and extrapyramidal symptoms were assessed using the 18 item-Brief Psychiatric Rating Scale (BPRS-18), Global Assessment of Functioning (GAF), and Drug-Induced Extrapyramidal Symptom Scale (DIEPSS), respectively. We examined differences in these clinical variables between "inactive," "minimally active," and "health enhancing physical activity" groups. Linear regression analysis was used to examine the clinical factors explaining low PA levels in patients with schizophrenia.

RESULTS

Subjects spent an average of 130.18±238.89 min/wk on moderate/vigorous-intensity PA and only 26% of them met the recommended PA guideline of 150 minutes of at least moderate PA per week. The inactive group showed significantly higher BPRS-18 and DIEPSS scores, and a lower GAF score than the other groups. Linear regression analysis showed that DIEPSS scores independently explained the amount of total PA (p=0.001) and time spent being sedentary (p=0.028).

CONCLUSION

This study provides preliminary evidence that extrapyramidal symptoms could be a major impediment to the PA of patients with schizophrenia.

Physical activity and metabolic disease among people with affective disorders: Prevention, management and implementation

BACKGROUND

One in ten and one in three of people with affective disorders experience diabetes and metabolic syndrome respectively. Physical activity (PA) and sedentary behaviour (SB) are key risk factors that can ameliorate the risk of metabolic disease among this population. However, PA is often seen as luxury and/or a secondary component within the management of people with affective disorders.

METHODS

The current article provides a non-systematic best-evidence synthesis of the available literature, detailing a number of suggestions for the implementation of PA into clinical practice.

RESULTS

Whilst the evidence is unequivocal for the efficacy of PA to prevent and manage metabolic disease in the general population, it is in its infancy in this patient group. Nonetheless, action must be taken now to ensure that PA and reducing SB are given a priority to prevent and manage metabolic diseases and improve wider health outcomes. PA should be treated as a vital sign and all people with affective disorders asked about their activity levels and if appropriate advised to increase this. There is a need for investment in qualified exercise specialists in clinical practice such as physiotherapists to undertake and oversee PA in practice. Behavioural strategies such as the self-determined theory should be employed to encourage adherence. Funding is required to develop the evidence base and elucidate the optimal intervention characteristics.

CONCLUSION

PA interventions should form an integral part of the multidisciplinary management of people with affective disorders and our article outlines the evidence and strategies to implement this in practice.
