A randomized controlled trial of mindfulness: effects on university students' mental health.

BACKGROUND: The development of mental health disorders is common in the university population, and mindfulness-based interventions (MBIs) seem to be effective in addressing them in different contexts. Thus, this study investigated the impact of an 8-week MBI adapted to university students from the Mindfulness-Based Relapse Prevention (MBSR) on different symptoms related to mental health problems, specifically symptoms of anxiety, depression, stress and insomnia. METHODS: University students (n = 136) were randomized into MBI group (n = 71) or wait-list group (n = 65). All participants completed self-administered questionnaires before and after the intervention, and the experimental group answered questionnaires weekly during intervention. Generalized mixed models were used to assess the effects of the intervention. RESULTS: There were improvements in the symptoms of stress (B = 5.76, p < 0.001), depression (B = 1.55, p < 0.01) and insomnia (B = 1.35, p = 0.020) from the beginning of the intervention to the final assessment when it was compared to the control group. No effect was found in respect of trait anxiety. The MBI was found to be effective in reducing important symptoms related to university students' mental health, possibly grounding further research on the intervention's potential of preventing the development of mental disorders. TRIAL REGISTRATION: The research was registered in the Brazilian Registry of Clinical Trials (ReBEC) - number RBR-63qsqx, approved at 09/16/2019.

Psychometric properties of the short version of the Five Facets of Mindfulness Questionnaire in brazilian portuguese / Propriedades psicométricas da versão curta do Questionário das Cinco Facetas de Mindfulness em português / Propiedades psicométricas de la versión corta del Cuestionario de las Cinco Facetas de Mindfulness en portugués

The aims of the current study were to evaluate the psychometric properties of a short version of the Five Facet Mindfulness Questionnaire (FFMQ-SF-BR) and verify if the addition of wording mechanisms (positive or negative) contributes to the fit of the shortened Brazilian Portuguese version of the FFMQ. Four hundred eight participants answered self-report measurements. Structural equation modelling was employed for both objectives. Adequate model fit was found for the 5-factor FFMQ-SF-BR model, with significant improvements arising from the addition of wording mechanism effects. No evidences of differential item functioning and population heterogeneity were found. Bifactor analysis showed that latent traces are preferred overusing raw sum scores. The FFMQ-SF-BR is suitable to measure mindfulness in the Brazilian population and has the benefits of decreasing data collection length without losing content coverage. (AU)

O presente estudo objetivou avaliar as propriedades psicométricas de uma versão curta em português do Questionário das Cinco Facetas de Mindfulness (FFMQ-SF-BR) e verificar se a adição de mecanismos de formulação dos itens (positivos ou negativos) contribui para o ajuste do modelo em cinco fatores. Quatrocentos e oito participantes preencheram instrumentos de autorrelato. Modelagem de equações estruturais foi aplicada em ambos os objetivos. Índices adequados de ajuste foram encontrados para o modelo em cinco fatores, com melhorias significativas advindas da adição dos mecanismos de formulação dos itens. Não foram encontradas evidências de funcionamento diferencial dos itens ou heterogeneidade populacional. A análise de um modelo bifator demonstrou que valores de traços latentes são preferíveis à soma da pontuação. A FFMQ-SF-BR é adequada para mensurar mindfulness na população brasileira, com os benefícios de diminuir o tempo de coleta sem perda de conteúdo. (AU)

The contribution of mindfulness to outpatient substance use disorder treatment in Brazil: a preliminary study

Objective: To explore the contribution of a mindfulness-based intervention as an adjuvant to outpatient substance use disorder treatment. Outcomes included substance use behavior, depression and anxiety symptoms, and anger expression. Methods: This preliminary study for a pragmatic randomized controlled trial with stratified random allocation included three months of follow-up. In two outpatient clinics linked to public universities, a mindfulness-based intervention plus treatment as usual (experimental group n=22) was compared to treatment as usual (control group n=20). The study included data from self-report measurements and the patients' records, which were evaluated according to intention-to-treat analysis through generalized estimating equations and generalized method of moments estimation. Results: The experimental group had lower symptoms of depression (b=-6.82; 95%CI -12.45 to -1.18) and anxiety (b=-0.25; 95%CI -0.42 to -0.09), and anger expression (b=-9.76; 95%CI -18.98 to -0.54) three months after the intervention. We detected no effect on substance use behavior. Conclusion: The mindfulness-based intervention yielded promising results as an adjuvant to outpatient substance use disorder treatment, since it reduced levels of highly prevalent symptoms in this population. However, further studies with longer follow-up periods and larger samples are required.

Alcohol and tobacco consumption concordance and its correlates in older couples in Latin America.

AIM: As little is known about alcohol and tobacco consumption concordance between older spouses in low- and middle-income countries, the present study aimed to estimate this in older couples from five Latin American countries. METHODS: This study is a secondary analysis of data collected between 2003 and 2007 by the 10/66 Dementia Research Group, from 1451 couples aged over 65 years from Cuba, the Dominican Republic, Peru, Mexico and Puerto Rico. Kappa statistic was used to assess the agreement of the behavior beyond chance, and logistic regression models with meta-analyses were used to estimate the factors associated with concordance. RESULTS: The mean age of the total sample was 74.8 years (SD 6.6). The results showed high levels of agreement rates in relation to drinking and smoking (75.9% and 85% of couples, respectively, did not drink or smoke), which were beyond the agreement expected by chance. Increased age was associated with concordance on both being non-drinkers (OR 1.03, 95% CI 1.01-1.05) and non-smokers (OR 1.05, 95% CI 1.02-1.07); and having a larger social network was associated with less likelihood of the couple being non-drinkers (OR 0.93, 95% CI 0.88-0.98). Attending religious meetings was associated with increased likelihood of the couple being non-smokers (OR 1.19, 95% CI 1.01-1.41). Socioeconomic circumstances were not associated with couples' concordance. CONCLUSIONS: Older Latin American couples have high levels of concordance in drinking and smoking habits, which increases with age, and were not associated with socioeconomic circumstances, but were with social network. This knowledge can assist the development of policies and interventions to promote health among this growing population. Geriatr Gerontol Int 2017; 17: 1849-1857.

Effect of Diamel in patients with metabolic syndrome: a randomized double-blind placebo-controlled study.

BACKGROUND: The aim of the present study was to determine whether the administration of Diamel, marketed as a food supplement by Catalysis Laboratories (Madrid, Spain) could improve any of the components of metabolic syndrome (MS), as well as insulin resistance and sensitivity. METHODS: In all, 100 patients with MS (19-70 years of age) who satisfied the World Health Organization criteria for MS were included in the study. Participants were randomly assigned to receive either oral Diamel or a placebo (while maintaining a diet appropriate to their weight and physical activity) at a dose of two capsules before each of the three main meals each day for 1 year. Anthropometric indices, blood pressure, fasting plasma glucose, lipid profile, insulin, creatinine, and uric acid (UA) were determined. Insulin resistance (IR) was assessed and three indirect indices were used to calculate insulin sensitivity (IS). RESULTS: Compared with placebo, Diamel improved fasting insulin concentrations, IS, and IR and reduced UA concentrations from 6 months until the end of treatment (P < 0.05 for all). In addition, after 12 months treatment with Diamel, significant changes from baseline were seen for mean fasting insulin (P < 0.05), UA (P < 0.05), IR (P < 0.001), and IS (P < 0.001), whereas no such changes were seen in the placebo-treated group. Improvements were noted in body mass index, IR, and IS in both groups. CONCLUSIONS: Long-term Diamel treatment, combined with lifestyle changes, was beneficial for IR and IS, and reduced serum UA levels in patients with MS.

Caracterización de redes de apoyo social para adultos mayores de un grupo básico de trabajo / Characterization of social help networks for the elderly of a working basic group

La investigación se orientó a caracterizar las redes de apoyo social en adultos mayores pertenecientes al Grupo Básico de Trabajo # 3 del policlínico “Capitán Roberto Fleites”, en la ciudad de Santa Clara. Se realizó un estudio con diseño descriptivo, y la muestra quedó constituida por 305 ancianos, escogidos mediante un muestreo estratificado bietápico, que constituyen el 13,14 por ciento de la población del grupo Básico de Trabajo. Se aplicó una entrevista estructurada a diferentes fuentes: ancianos, miembros de la red, médicos y enfermeros de la familia, triangulando la información obtenida. Los datos fueron almacenados en un fichero mediante el programa computacional SPSS versión 9.0. Se aplicó la prueba de Chi cuadrado para comparar los por cientos correspondientes a las diferentes categorías de una variable. Las redes de apoyo social se caracterizaron por tener una baja diversidad en la composición, y se centró en los hijos el cuidado de los ancianos, con una funcionabilidad deficiente y una conducta de apoyo que no satisface las necesidades específicas de los adultos mayores, por lo que el grado de efectividad de las redes de apoyo social es insuficiente(AU)
