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 .
Correlates of body mass index and overweight and obesity of children aged 2 years: findings from the healthy beginnings trial.
OBJECTIVE We sought to determine early life factors that predict body mass index ( BMI ) and overweight/obesity  of children aged 2 years . METHODS A longitudinal and prospect i ve analysis was conducted with 330 first-time mothers and their newborns . Children 's weight and length were measured at 2 years . Main factors of interest included reported infant feeding practice s , children 's fruit/vegetable consumption , and television ( TV ) time . Maternal demographic data , weight and height , and smoking status were collected by face-to-face interview at baseline . Multiple linear and logistic regression models were run to determine factors that predicted BMI or overweight/obesity of children aged 2 years , respectively . RESULTS At age 2 years , 242 remained in the study ( retention rate 73 % ) . Mean ( SD ) BMI of children was 16.87 kg/m(2 ) ( 1.62 ) , with 14 % classified as overweight/obese . Factors predicting lower child BMI were longer breastfeeding duration , less TV viewing time , and lower child 's birth weight as well as maternal healthy prepregnancy weight status . Factors predicting children 's overweight/obesity status were shorter breastfeeding duration , earlier introduction of solid food , and maternal overweight or obesity . CONCLUSIONS At 2 years of age , longer breastfeeding duration was associated with lower BMI , while greater TV viewing time was associated with higher BMI , after adjusting for other factors . Early introduction of solids and maternal overweight or obesity were independently associated with overweight or obesity
