Associations between objective ly measured total sedentary time and indicators of adiposity and motor development were predominantly null .
Associations between screen time and indicators of adiposity , motor or cognitive development , and psychosocial health were primarily unfavourable or null .
Associations between time spent seated ( e.g. , in car seats or strollers ) or in the supine position , and indicators of adiposity and motor development , were primarily unfavourable or null .
Conclusions These findings continue to support the importance of minimizing screen time for disease prevention and health promotion in the early years , but also highlight the potential cognitive benefits of interactive non-screen-based sedentary behaviours such as reading and storytelling .
Background The purpose of this systematic review was to examine the relationships between  sedentary behaviour ( SB ) and health indicators in children aged 0 to 4 years , and to determine what doses of SB ( i.e. , duration , patterns [ frequency , interruptions ] , and type ) were associated with health indicators .
Risk factors for overweight in 2- to 6-year-old children in Beijing, China.
OBJECTIVE To assess the prevalence of overweight among Chinese preschool children and to explore risk factors of childhood obesity focusing on parental characteristics , feeding practice and lifestyle . METHODS Data on 930 families with 2- to 6-year-old children in five kindergartens were obtained in a cross sectional study . Families were r and omly selected from two of all six urban districts in Beijing , China . Information on parental characteristics , dietary habits , lifestyle habits , and feeding practice was collected by parental self-report question naires . The children 's stature and weight were measured in light clothing and without shoes . Overweight and obesity were defined according to international cut-off values , as proposed by the International Obesity Task Force . Multivariate regression analysis was used to explore risk factors of child overweight . RESULTS The overall prevalence of overweight and obesity was 10.7 % and 4.2 % , respectively , and increased with age . The prevalence of child overweight was 14.1 % and 7.5 % in obese and non-obese families , respectively . Significant associations were observed between child and parent characteristics for overweight , frequency of eating in restaurant , television hours , and hours of physical activity . Child overweight was associated with parental overweight ( Odds Ratio [ OR ] 2.43 , 95 % CI 0.78 , 6.59 ) , low maternal education level ( OR 2.22 , 95 % CI 1.39 , 3.55 ) , food restriction ( OR 2.68 , 95 % CI 1.64 , 4.29 ) , and television watching > 2h/d ( OR 1.56 , 95 % CI 1.17 , 2.09 ) , after adjusting for sex , age , family income and kindergarten ( for cluster study design ) . CONCLUSIONS Overweight prevalence among Chinese preschool children in Beijing is comparable to some European countries . Prevention strategies should include identified lifestyle risk factors
