Growth and motor performance of healthy Senegalese preschool children

Area of Science:

• Pediatric Growth and Development
• Human Motor Performance
• Nutritional Science

Background:

• Assessing physical development in Senegalese children is crucial for understanding growth patterns.
• Previous generations of Senegalese children exhibited different growth trajectories.

Purpose of the Study:

• To evaluate body dimensions, motor performance, and aerobic fitness in young Senegalese children.
• To compare growth and performance against reference data and previous generations.

Main Methods:

• Measurements included body dimensions, motor performance tests, and aerobic stress tests.
• Data collected across three occasions from 88 healthy Senegalese children (3-6 years old).
• Children grouped by birth year (1985, 1984, 1983) for cohort analysis.

Main Results:

• Senegalese children exhibited linear growth near North American standards but had significant weight deficits.
• Boys (born 1983) showed greater muscularity and less arm fat than girls.
• Motor performance was lower than European children, but normalized for body mass, differences decreased.
• Age, body weight, and stature were key predictors of motor performance variations.

Conclusions:

• Senegalese children's growth is progressing favorably compared to earlier generations.
• Nutritional factors are critical for optimizing physical performance and cardiorespiratory fitness in this population.
• Further research into nutritional interventions is recommended to enhance child development.
