Lifestyle intervention based on exercise and behavioural counselling and its effect on physical and psychological health in outpatients with schizophrenia spectrum disorders. An exploratory, pragmatic randomized clinical trial.

Patients with Schizophrenia Spectrum Disorders (SSD) often lead unhealthy lifestyles. This pragmatic trial evaluated the effectiveness of a lifestyle intervention, consisting of a 12-week aerobic exercise program and behavioural counselling, in SSD outpatients with metabolic syndrome (MetS). It also aimed to assess persistence of potential effects in a 24-month long-term follow-up. Effectiveness was measured in terms of a wide range of outcomes involving physical and psychological health, quality of life, physical activity and changes in motivation to exercise within the context of the self-determination theory. Our primary outcome was waist circumference change. Thirty-three out of 48 participants completed the study. No differences between groups were found in terms of BMI change or other metabolic parameters. However, the active group (AG) showed improvement regarding waist circumference, negative symptomatology and identified motivation to exercise during the study and follow-up. The AG exhibited changes toward a more active pattern of activity after intervention. Moreover, belonging to the AG was a significant predictor for achieving any degree of clinical improvement after 24-month follow-up. Combined interventions of exercise and behavioural counselling in SSD patients with MetS should be considered as an essential part of the integral treatment in the context of mental health services.

In- and outpatient lifestyle interventions on diet and exercise and their effect on physical and psychological health: a systematic review and meta-analysis of randomised controlled trials in patients with schizophrenia spectrum disorders and first episode of psychosis.

Patients with non-affective psychosis often lead unhealthy lifestyles. We performed a systematic review and meta-analysis on non-pharmacological RCTs for improvement of diet and physical activity in non-affective psychosis patients, including first-episode psychosis. A variety of outcomes was analysed, including metabolic, psychopathology, cognitive, functional and quality of life outcomes. Fifty-nine studies were included. An improvement in anthropometric measurements (BMI, weight, waist circumference) was observed post-intervention, persisting after follow-up. Post-intervention benefit was found also for psychotic symptoms severity (also persisting after follow-up), many cognitive domains and physical and global functioning and quality of life. Conversely, no effect was observed in relation to most blood metabolites, blood pressure and non-psychotic psychopathology and spontaneous physical activity. Improvement was generally larger for interventions including exercise, especially moderate/vigorous aerobic exercise, but follow-up maintenance was greater for psychotherapy interventions. Sensitivity analyses limited to chronic stages of psychosis and low risk of bias studies produced comparable results. Further studies are needed to design optimized interventions in this vulnerable population.

Surfing scientific output indexed in the web of science and scopus (1967-2017) / Produção científica do surfe indexada na web of science e scopus (1967-2017) / Producción científica de surfing indexada en la web of science y scopus (1967-2017)

Abstract: The aim of this study was to carry out a bibliometric analysis of the surfing scientific output indexed in the Web of Science and Scopus until 2017 focused on productivity, subjects and collaboration patterns. A total of 318 documents published from 1967 to 2017 were discovered. Medical Sciences was the most represented field and the percentage of collaboration achieved 69.18%. Only Australian institutions were represented within the top ten authors. Although surfing has become an emerging research field, it appears to be a rare case within Sport Sciences due to the leading role of Australian institutions.

Resumo: O objetivo deste trabalho foi desenvolver uma análise bibliométrica da produção científica do surfe indexada na Web of Science e Scopus até 2017 centrada na produtividade, matérias e padrões de colaboração. Descobriram-se um total de 318 documentos publicados de 1967 até 2017. Ciências médicas foi o campo mais representado e a percentagem de colaboração foi de 69,18%. Nos dez autores mais importantes só se acharam representadas instituições australianas. Embora o surfe tenha se tornado uma área de investigação emergente, parece ser um sujeito excepcional nas Ciências do Esporte devido ao papel dominante das instituições australianas .

Chilean sport sciences scientific production indexed in the Web of Science (1981-2016)

AIM: To carry out a bibliometric analysis of the Chilean Sport Sciences scientific production indexed in the Web of Science until 2016. METHODS: Chilean Sport Sciences articles and reviews included in the Web of Science Core Collection indexes until 2016 were analyzed. Data was collected and filtered in Endnote X6 programme and then exported to Excel 2013, Bibexcel and Histcite for analysis. Bibliometrics was focused on productivity, subjects and collaboration patterns. RESULTS: A total of 152 documents published from 1981 to 2016 were found. Life Sciences was the main research area (104), while Physiology (36) and Sports Training Theory (30) were the most represented subjects. The mean of authors per article was 5.26 and the percentage of collaboration was mainly between 94% and 100%. Ramirez-Campillo was the most prolific author (24) and Caniuqueo achieved the highest collaboration index (10.83). Two networks, with 20 and 10 scholars respectively and representing 19 different institutions, were discovered. A cluster of 53 different journals has disseminated Chilean Sport Sciences publications, but 12 of them collected 60.53% of total production. CONCLUSION: Chilean Sport Sciences scientific production indexed in the Web of Science shows the progressive development and strengthening of this field of knowledge, clearly oriented to Life Sciences, teamwork and international collaboration. The establishment of a network including scholars from Australia, Brazil, Canada, Chile and Spain, which is propelling Sport Sciences research in this country, should be also highlighted.(AU)
