    Common mental disorders in Peruvian immigrant in Chile: a comparison with the host population
    (BMC, 2023) Errazuriz, Antonia; Schmidt, Kristin; Valenzuela, Paulina; Pino, Rodolfo; Jones, Peter B. B.
    BackgroundThe Inner Santiago Health Study (ISHS) aimed to (i) estimate the prevalence of common mental disorders (CMD; i.e. depressive and anxiety disorders) among immigrants of Peruvian origin in Chile; (ii) determine whether such immigrants are at higher risk of CMD when compared with the native-born geographically matched population (i.e. non-immigrants); and (iii) identify factors associated with higher risk of any CMD among this immigrant group. A secondary aim was to describe access to mental health services by Peruvian immigrants meeting criteria for any CMD.MethodsFindings are based on a population-based cross-sectional household mental health survey of 608 immigrant and 656 non-immigrant adults (18-64 years) residing in Santiago de Chile. Diagnoses of ICD-10 depressive and anxiety disorders and of any CMD were obtained using the Revised Clinical Interview Schedule. The relationships between demographic, economic, psychosocial, and migration-specific predictor variables, and risk of any CMD were analyzed with a series of stepwise multivariate logistic regression models.ResultsThe one-week prevalence of any CMD was 29.1% (95% CI: 25.2-33.1) among immigrants and 34.7% (95% CI: 30.7-38.7) among non-immigrants. Depending on the statistical model used in the pooled sample, we found the prevalence of any CMD among non-immigrants to be higher (OR=1.53; 95% CI: 1.05-2.25) or similar (OR=1.34; 95% CI: 0.94-19.2) when compared with immigrants. In the multivariate stepwise regression of any CMD in immigrants only, the prevalence was higher for females, those with primary compared to higher education, in debt and exposed to discrimination. Conversely, higher levels of functional social support, sense of comprehensibility, and manageability were associated with a lower risk of any CMD in immigrants. In addition, no differences were observed between immigrants and non-immigrants reporting any CMD in mental health service utilization.ConclusionOur results evidence high levels of current CMD in this immigrant group, particularly amongst women. However, lower adjusted prevalence of any CMD in immigrants compared to non-immigrants was limited to preliminary statistical models, thus failing to provide clear support for a "healthy immigrant effect". The study sheds new light on differences in CMD prevalence by immigrant status in Latin America by examining differential exposure to risk factors in immigrant versus non-immigrant groups.

    Effects of mindfulness-based stress reduction on psychological distress in health workers: A three-arm parallel randomized controlled trial
    (Pergamon-Elsevier Science Ltd., 2022) Errazuriz Concha, Antonia; Schmidt, Kristin; Undurraga Fourcade, Eduardo Andrés; Medeiros Urzua, Sebastián; Baudrand Biggs, René Felipe; Cussen Sanhueza, Diego; Henríquez Henríquez, Marcela Patricia; Celhay, Pablo; Figueroa, Rodrigo A.
    Mindfulness-based Stress Reduction (MBSR) has shown good efficacy for improving wellbeing in employees experiencing occupational stress. However, comparisons with other interventions, longer-term follow-up, and data from varying sociocultural contexts are lacking. This three-arm, parallel randomised controlled trial (RCT) examined the effects of MBSR on psychological distress in non-physician health workers in direct contact with patients. 105 participants were randomly allocated to either: (1) MBSR (N = 35), (2) Stress Management Course (SMC; N = 34) or (3) wait-list (N = 36). Participants and those assessing outcomes were blinded to group assignment. Participants completed questionnaires pre- and post-intervention and four months after the intervention. Psychological distress was measured using the General Health Questionnaire (GHQ-12) and Outcome Questionnaire (OQ-45). Secondary outcomes included perceived stress, job satisfaction, mindfulness skills and changes in salivary cortisol. 77 participants completed measures post-intervention and 52 at 4-month follow-up. MBSR showed a post-intervention effect in reducing GHQ-12 (ss = -0.80 [SE = 1.58] p < 0.01) and OQ-45 (ss = -0.72, [SE = 5.87] p < 0.05) psychological distress, compared to SMC and in reducing GHQ-12 (ss = -1.30 [SE = 1.38] p < 0.001) and OQ-45 (ss = -0.71, [SE = 5.58] p < 0.01) psychological distress compared to wait-list condition. In our secondary outcome, only MBSR was associated with a decrease in the cortisol awaking response by 23% (p < 0.05). At follow-up, only effects of MBSR on the psychological distress 'social role' subscale (ss = -0.76 [SE = 1.31] p < 0.05) remained significant, compared to SMC. In conclusion, MBSR appears useful in reducing short-term psychological distress in healthcare workers, but these effects were not maintained at followup. Trial registration: ISRCTN12039804.
