Mean baseline age ranged from 18.3聽weeks-59.79聽months; where mean age was not reported, baseline age ranged from 0聽months-5聽years. Data were collected by RCT, clustered RCT, non-randomized intervention, longitudinal with up to 20-month follow-up, and cross-sectional study designs. Motor development was assessed by fundamental movement skills/motor ability/motor performance/motor development/motor skills/gross-motor development/psychomotor skills (objectively measured; Test of Gross Motor Development 鈥 2, movement assessment battery, Movement Assessment Battery for Children 鈥 2, APM-Inventory, Dutch Second Edition of the Bayley Scales of Infant and Toddler 鈥 3, Motoriktestf眉rvier-bissechsj盲hrige Kinder 4-6; 12-m run, standing long jump, Motor Test Battery 3-7, Alberta Infant Motor Scales, neurological examination technique for toddler-age, Children鈥檚 Activity and Movement in Preschool Study Motor Skill Protocol, Comprehensive Developmental Inventory for Infants and Toddlers, Gessel Development Schedules 鈥 Development Quotient, adapted measures from the Zurich Neuromotor Assessment test), achievement of developmental milestones (proxy-report questionnaire), coordination (proxy-report questionnaire), and fine motor coordination/fine motor development (proxy-report interview; Comprehensive Developmental Inventory for Infants and Toddlers). | |||||||||
4 | RCTa | Serious risk of biasb | No serious inconsistency | Serious indirectnessc | No serious imprecision | None | 705 | The PA interventions (planned passive cycling or structured/organized PA) were favourably associated with improved motor development in 3 studies [90,91,92]. The PA intervention (PA recommendations from nurse) was not associated with improved motor development in 1 study [40]. | LOWd |
2 | Clustered RCTe | Serious risk of biasf | No serious inconsistency | Serious indirectnessg | No serious imprecision | None | 1564 | The PA intervention (structured/organized PA) was favourably associated with improved motor development (total score and jumping individual score but not for running, hopping, catching, and kicking) in 1 study [33]. The PA intervention (government-led PA program) was not associated with motor development in 1 study [41]. | LOWh |
6 | Non-randomized interventioni | Serious risk of biasj | No serious inconsistency | No serious indirectness | No serious imprecision | None | 946 | The PA interventions (free play and structured activities, structured/organized PA, dance, or swimming) were favourably associated with improved motor development (boys only and running speed between time 2 and 3 only in 1 study; one-leg balance only in 1 study) in 6 studies [36, 42, 93,94,95,96]. | VERY LOWk |
1 | Longitudinall | Serious risk of biasm | No serious inconsistency | No serious indirectness | No serious imprecision | None | 197 | Prone position was favourably associated with motor development (higher prone duration and gross motor development only at age 6 mo but not at age 24 mo and prone-specific milestones only) [97]. | VERY LOWn |
10 | Cross-sectionalo | Serious risk of biasp | No serious inconsistency | No serious indirectness | No serious imprecision | Exposure/outcome gradientq | 1833 | TPA was favourably associated with motor development (correlations but not when comparing quartiles of fundamental movement skills in 1 study) in 3 studies [56, 69, 100], unfavourably associated with motor development (running speed only in 1 study) in 2 studies [81, 101], and not associated with motor development in 1 study [86]. LPA was not associated with motor development in 3 studies [67, 86, 100]. LPA 5-min bouts were not associated with motor development in 1 study [86]. MVPA was favourably associated with motor development (total and locomotor [high vs. low only] but not for object control skills in 1 study) in 3 studies [67, 69, 100] and not associated with motor development in 1 study [86]. MVPA 5-min bouts were not associated with motor development in 1 study [86]. VPA was favourably associated with motor development (total and locomotor [high vs. low only] but not for object control skills) in 1 study [67]. Indoor PA was favourably associated with motor development (throwing at target only) in 1 study [81]. Outdoor PA was not associated with motor development in 1 study [81]. Prone position was favourably associated with motor development (gross motor development but not fine motor development in 1 study) in 3 studies [97,98,99]. | VERY LOWr |
