37 min of average view duration), and tablets (6318 min of watch time, 768 views, and 8.23 min of average view duration). CONCLUSION Majority of the viewers used mobile phones, and mobile phones and tablets had significantly longer average view durations as compared to computer/TV. YouTube and wireless devices may have potential as internet based psychiatric emergency outreach platform. This study calls for further research to explore the effectiveness of using social media and wireless devices for psychiatric emergency education prior to ED arrival, particularly in minority populations with cultural barriers to health care. OBJECTIVE To analyze the association between four key different physical activity (PA) domains and depressive symptoms among Brazilian adults. METHODS Data from the Brazilian National Health Survey (n = 60,202; ≥18 years) were used. PA across four different domains (leisure, transport, occupational and household) was collected through specific questionnaires. The cutoff point adopted in each domain was 150 min/week. Depression was evaluated through the Patient Health Questionnaire-9. Multivariable adjusted linear and logistic regression models were applied. RESULTS Leisure PA was associated with lower depressive symptoms [β -0.008 (95% CI -0.010 to -0.005); OR 0.69 (95% CI 0.59 to 0.81)]. Transport PA was also associated with lower depressive symptoms among older adults [β -0.008 (-0.012 to -0.003); OR 0.70 (95% CI 0.53-0.94)] but not middle-aged adults. On the other hand, occupational PA [β 0.003 (95% CI 0.002 to 0.005); OR 1.62 (95% CI 1.38 to 1.91)] and household PA [β 0.009 (95% CI 0.006 to 0.012); OR 1.57 (95% CI 1.37 to 1.79)] were associated with higher depressive symptoms. CONCLUSION The association between PA and depression symptoms varies according to the domains of PA and some appear independent from each other. While leisure PA is associated with fewer depressive symptoms; occupational and household PA appear to be associated with an increased depression risk. BACKGROUND Cash transfer programs have grown increasingly popular and are now used as interventions to target a wide array of health outcomes across many diverse settings. However, cash transfer experiments have yielded mixed results, highlighting gaps in our understanding of how these programs work. In particular, we do not yet know whether cash transfers are more effective for certain health outcomes compared to others, or are more effective for some population subgroups compared to others. Here, we ask whether the effects of cash transfers on health outcomes differ across study subgroups. METHODS We reviewed the literature on cash transfer experiments conducted in low and middle income countries, published in English between 1985 and 2015. We documented whether the investigators reported either i) stratum-specific estimates or ii) the interaction term between subgroups and exposure to the intervention. For studies that presented stratum-specific estimates without statistical tests for heterogeneity, we assessed heterogeneity across subgroups with a Cochran Q test. RESULTS Of the 56 studies we reviewed, 40 reported effects on study subgroups. The majority of the cash transfer interventions had different magnitudes of effects on health across subgroups. This heterogeneity was often underreported or not formally analyzed. We find substantial heterogeneity of cash transfers on child health and on adult health yet little heterogeneity of cash transfers on sexual and reproductive health. CONCLUSIONS Accounting for the heterogeneous impacts of cash transfers during program design and evaluation is necessary to better target cash transfer programs and generate more precise data on their effects. INTRODUCTION There are concerns about young people's increasing use of social media and the effects this has on overall life satisfaction. Establishing the significance of social media use requires researchers to take simultaneous
