There is a large body of evidence from all study design s which suggests that decreasing any type of sedentary time is associated with lower health risk in youth aged 5 - 17 years .
In particular , the evidence suggests that daily TV viewing in excess of 2 hours is associated with reduced physical and psychosocial health , and that lowering sedentary time leads to reductions in BMI
Accumulating evidence suggests that , independent of physical activity levels , sedentary behaviours are associated with increased risk of cardio-metabolic disease , all-cause mortality , and a variety of physiological and psychological problems .
Therefore , the purpose of this systematic review is to determine the relationship between sedentary behaviour and health indicators in school-aged children and youth aged 5 - 17 years .
The Completeness of Reporting (CORE) index identifies important deficiencies in observational study conference abstracts.
OBJECTIVE The aim was to develop , test , and apply an index to assess the completeness of reporting in a cohort of observational studies of conference abstract s. STUDY DESIGN AND SETTING Using rigorous methods , we reduced 245 items generated by literature review to 48 c and i date items . In a r and om sample of 30 conference abstract s of rituximab for nonHodgkin lymphoma , we developed an item impact score using a survey of abstract stakeholders combined with the prevalence of each of the 48 items . We retained 14 independent items representing completeness of reporting , the CORE-14 . Two raters determined the reliability of the instrument . We then applied the CORE-14 in another 78 studies to determine the prevalence of each feature . RESULTS Our survey response rate was 83.9 % ( 47/56 ) . Interrater reliability ( 95 % CI ) of the CORE-14 instrument was 0.56 ( 0.25 , 0.77 ) , which improved by averaging across scores provided by two raters ( 0.72 [ 0.49 , 0.86 ] ) . Applying the CORE-14 in an additional set of 78 abstract s , six items occurred > or = 85 % and four items occurred < or = 40 % of the time . CONCLUSION Opportunities to improve conference abstract reporting exist . This scale could guide future conference abstract su bmi ssions and aid individuals considering conference abstract data to inform clinical practice , systematic review s , guidelines , or policy
