In conclusion , very little is known about sedentary behaviors other than screen time in this age group .
Although highly variable , findings suggest that children are already engaging in high levels of screen time by age 2 and the majority exceed current recommendations
Sedentary behavior has negative health outcomes , evident even in young children .
Identifying the prevalence of sedentary behavior in children < 2years is important for determining the necessity for intervention strategies .
The aim of this systematic review was to determine the prevalence of sedentary behavior in children < 2years .
A Parent-Focused Intervention to Reduce Infant Obesity Risk Behaviors: A Randomized Trial
OBJECTIVE : To assess the effectiveness of a  parent-focused intervention on  infants ’ obesity-risk behaviors and BMI . METHODS : This cluster r and omized controlled trial recruited 542 parents and their infants ( mean age 3.8 months at baseline ) from 62 first-time parent groups . Parents were offered six 2-hour dietitian-delivered sessions over 15 months focusing on parental knowledge , skills , and social support around infant feeding , diet , physical activity , and television viewing . Control group parents received 6 newsletters on nonobesity-focused themes ; all parents received usual care from child health nurses . The primary outcomes of interest were child diet ( 3 × 24-hour diet recalls ) , child physical activity ( accelerometry ) , and child TV viewing ( parent report ) . Secondary outcomes included BMI z-scores ( measured ) . Data were collected when children were 4 , 9 , and 20 months of age . RESULTS : Unadjusted analyses showed that , compared with controls , intervention group children consumed fewer grams of noncore drinks ( mean difference = –4.45 ; 95 % confidence interval [ CI ] : –7.92 to –0.99 ; P = .01 ) and were less likely to consume any noncore drinks ( odds ratio = 0.48 ; 95 % CI : 0.24 to 0.95 ; P = .034 ) midintervention ( mean age 9 months ) . At intervention conclusion ( mean age 19.8 months ) , intervention group children consumed fewer grams of sweet snacks ( mean difference = –3.69 ; 95 % CI : –6.41 to –0.96 ; P = .008 ) and viewed fewer daily minutes of television ( mean difference = –15.97 : 95 % CI : –25.97 to –5.96 ; P = .002 ) . There was little statistical evidence of differences in fruit , vegetable , savory snack , or water consumption or in BMI z-scores or physical activity . CONCLUSIONS : This intervention result ed in reductions in sweet snack consumption and television viewing in 20-month-old children
