Insights
Gross motor development in Greek infants mirrors Canadian norms, with AIMS percentile curves established. Maternal education and caregiver type significantly influence infant motor skills.
Area of Science:
- Pediatrics
- Developmental Pediatrics
- Child Health
Background:
- Gross motor development is a key indicator of infant health.
- Establishing normative data is crucial for identifying developmental delays.
- Previous studies have focused on North American populations.
Purpose of the Study:
- To investigate gross motor development in Greek infants using the Alberta Infant Motor Scale (AIMS).
- To establish AIMS percentile curves for Greek infants.
- To examine the association between AIMS scores and socioeconomic factors.
Main Methods:
- AIMS scores of 1068 healthy Greek infants were compared monthly to a Canadian normative sample.
- Socioeconomic data were collected from 345 infants' families via interviews.
- Multiple linear regression analyzed the relationship between motor development and socioeconomic parameters.
Main Results:
- Greek and Canadian infants showed no significant differences in mean AIMS scores across 19 monthly age levels.
- Maternal educational level and infant care arrangements (grandparents/babysitter) were significantly associated with motor development.
- No significant correlation was found with gender, birth order, maternal age, paternal education, or family income.
Conclusions:
- The gross motor development of Greek infants aligns with the Canadian AIMS normative data.
- Specific socioeconomic factors, particularly maternal education and caregiving arrangements, play a role in infant motor development.
- These findings contribute to understanding developmental trajectories and influencing factors in diverse populations.
Objective:
The aims of this study were to investigate gross motor development in Greek infants and establish AIMS percentile curves and to examine possible association of AIMS scores with socioeconomic parameters.
Methods:
Mean AIMS scores of 1068 healthy Greek full-term infants were compared at monthly age level with the respective mean scores of the Canadian normative sample. In a subgroup of 345 study participants, parents provided, via interview, information about family socioeconomic status. Multiple linear regression analysis was performed to evaluate the relationship of infant motor development with socioeconomic parameters.
Results:
Mean AIMS scores did not differ significantly between Greek and Canadian infants in any of the 19 monthly levels of age. In multiple linear regression analysis, the educational level of the mother and also whether the infant was being raised by grandparents/babysitter were significantly associated with gross motor development (p=0.02 and p<0.001, respectively), whereas there was no significant correlation of mean AIMS scores with gender, birth order, maternal age, paternal educational level and family monthly income.
Conclusions:
Gross motor development of healthy Greek full-term infants, assessed by AIMS during the first 19months of age, follows a similar course to that of the original Canadian sample. Specific socioeconomic factors are associated with the infants' motor development.

Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
