    Input: The study objective was to evaluate the feasibility of a telephone delivered intervention consisting of motivational interviewing and cognitive behavioural strategies aim ed at improving diet and physical activity in people diagnosed with psychotic disorders . Twenty participants diagnosed with a non-acute psychotic disorder were recruited . The intervention consisted of eight telephone delivered sessions targeting fruit and vegetable ( F&V ) consumption and leisure screen time , as well as smoking and alcohol use ( as appropriate ) . F&V frequency and variety , and overall diet quality ( measured by the Australian Recommended Food Score , ARFS ) , leisure screen time , overall sitting and walking time , smoking , alcohol consumption , mood , quality of life , and global functioning were examined before and 4-weeks post-treatment . Nineteen participants ( 95 % ) completed all intervention sessions , and 17 ( 85 % ) completed follow-up assessment s. Significant increases from baseline to post-treatment were seen in ARFS fruit , vegetable and overall diet quality scores , quality of life and global functioning . Significant reductions in leisure screen time and overall sitting time were also seen . Results indicated that a telephone delivered intervention targeting key cardiovascular disease risk behaviours appears to be feasible and relatively effective in the short-term for people diagnosed with psychosis . A r and omized controlled trial is warranted to replicate and extend these findings Objectives To determine the impact of sitting and television viewing on  life expectancy in the USA . Design Prevalence-based cause-deleted life table analysis . Setting Summary RRs of all-cause mortality associated with sitting and television viewing were obtained from a meta- analysis of available prospect i ve cohort studies . Prevalences of sitting and television viewing were obtained from the US National Health and Nutrition Examination Survey . Primary outcome measure Life expectancy at birth . Results The estimated gains in life expectancy in the US population were 2.00 years for reducing excessive sitting to <3 h/day and a gain of 1.38 years from reducing excessive television viewing to < 2 h/day . The lower and upper limits from a sensitivity analysis that involved simultaneously varying the estimates of RR ( using the upper and lower bounds of the 95 % CI ) and the prevalence of television viewing ( ±20 % ) were 1.39 and 2.69 years for sitting and 0.48 and 2.51 years for television viewing , respectively . Conclusion Reducing sedentary behaviours such as sitting and television viewing may have the potential to increase life expectancy in the USA Background Evidence suggests a link between sedentary behaviours and depressive symptoms . Mechanisms underlying this relationship are not understood , but inflammatory processes may be involved . Autonomic and inflammatory responses to stress may be heightened in sedentary individuals contributing to risk , but no study has experimentally investigated this . Aims To examine the effect of sedentary time on mood and stress responses using an experimental design . Method Forty-three individuals were assigned to a free-living sedentary condition  and to  a control condition ( usual activity ) in a cross-over , r and omised fashion and were tested in a psychophysiology laboratory after spending 2 weeks in each condition . Participants completed mood question naires ( General Health Question naire and Profile of Mood States ) and wore a motion sensor for 4 weeks . Results Sedentary time increased by an average of 32 min/day ( P = 0.01 ) during the experimental condition compared with control . Being sedentary result ed in increases in negative mood independent of changes in moderate to vigorous physical activity ( ΔGHQ = 6.23 , ΔPOMS = 2.80 ) . Mood disturbances were associated with greater stress-induced inflammatory interleukin-6 ( IL-6 ) responses ( β = 0.37 ) . Conclusions Two weeks of exposure to greater free-living sedentary time result ed in mood disturbances independent of reduction in physical activity . Stress-induced IL-6 responses were associated with changes in mood OBJECTIVE Examine the association between sedentary behavior and psychiatric symptoms among overweight and obese adults with schizophrenia or schizoaffective disorders ( SZO/SA ) . DESIGN R and omized clinical trial ; Weight Assessment and Intervention in Schizophrenia Treatment ( WAIST ) Study : baseline data collected 2005 - 2008 . SETTING University of Pittsburgh Medical Center , Pittsburgh , PA , USA . PARTICIPANTS Community-dwelling adults diagnosed with SZO/SA , with mild symptom severity [ Positive and Negative Syndrome Scale (PANSS)<90 ] , who were interested in losing weight , age 18 - 70years , BMI > 27kg/m(2 ) . MEASUREMENTS Objective ly measured  sedentary behavior by accelerometry , and  psychopathology  assessed by PANSS . Participants wore the actigraphs for 7 consecutive days during their waking hours . Sedentary behavior was defined as ≤100 counts per minute during wear-time and excluded sleep and non-wear time . RESULTS On average , 81 % of the participant 's monitoring time or 756min/day was classified as sedentary behavior using accelerometry . No association was observed between sedentary behaviors and PANSS psychiatric symptoms [ total ( p≥0.75 ) , positive ( p≥0.81 ) , negative ( p≥0.59 ) and general psychopathology ( p≥0.65 ) subscales ] . No association was observed between sedentary behaviors and age , race , gender and BMI . CONCLUSION From a clinical and public health perspective , the amount of time ( approximately 13h ) and percentage of time ( 81 % excluding non-wear time associated with sleeping ) engaged in sedentary behavior among overweight and obese adults in this population is alarming , and points to an urgent need for interventions to decrease sedentary behaviors . The lack of associations between sedentary behavior and psychiatric symptoms may be due to a ceiling effect for sedentary behavior 
    Output:
    
Multivariate meta-regression confirmed that objective measurement of SB predicted higher levels of sedentariness .
People with psychosis engage in very high levels of sedentary behavior in their waking day and current SRQ may underestimate SB .
