Effects of Crawling before Walking: Network Interactions and Longitudinal Associations in 7-Year-Old Children

Area of Science:

• Developmental Pediatrics
• Human Movement Science
• Network Physiology

Background:

• Understanding developmental milestones like crawling before walking (CBW) is crucial for child development.
• Network interactions among physiological systems are key to overall health.
• Longitudinal studies are needed to assess the impact of early motor behaviors on later health outcomes.

Purpose of the Study:

• To investigate the impact of CBW on network interactions of body composition, cardiovascular, lung, motor, and physical fitness parameters at age 7.
• To assess the longitudinal associations between CBW and these parameters, plus physical activity, at age 7.

Main Methods:

• Seventy-seven healthy Caucasian children were assessed for CBW, body composition, cardiovascular system, lung function, motor competence, physical fitness, and physical activity.
• Network analyses were used to compare interaction patterns between crawling and non-crawling groups.
• Multiple regression analyses were employed for longitudinal associations.

Main Results:

• Network analyses showed the crawling group had more interconnected variables than the non-crawling group.
• Crawling was independently associated with higher fat mass (%), higher fat-to-muscle ratio, and higher systolic blood pressure.
• Models explained significant variance: 56.3% for fat mass, 56.7% for fat-to-muscle ratio, and 29.9% for systolic blood pressure.

Conclusions:

• CBW may act as a modulator of network interactions between different body systems during development.
• Early crawling behavior could influence future metabolic and cardiovascular health trajectories.
• These findings highlight the importance of early motor development for long-term physiological well-being.
