What are the three phases crucial to health during school age?
- Middle Childhood Growth (5-9)
- Adolescent Growth Spurt (10-14)
- Adolescent Growth Phase (15-19)
What is happening during middle childhood growth (5-9 years)?
- Infection and malnutrition constraint on development
- Mortality higher than previously thought
- Commonly micronutrient deficiencies
What is happening during the adolescent growth spurt (10-14 years)?
- BMI increases rapidly
- Substantial physiological and behavioural changes
- Adequate energy intake is crucial for growth
What is happening during the adolescent growth phase (15-19 years)?
- Further brain restructuring
- Increase exploration, experimentation
- Increased behaviours that are lifelong determinants of health
- More focused on brain growth
What does a healthy diet facilitate?
- Physical social/emotional and cognitive development
- Nutrients and health
- Steady growth
Physiological development is a time of…
Continued growth and development
What 3 things increase during physiological development?
- Muscular strength
- Motor co-ordination (more complex pattern movements)
- Stamina
Nutrient needs: Middle childhood vs. Early childhood
Lower nutrient needs in relation to body size than during early childhood
Boys vs. Girls: Body composition during middle childhood
Boys have more lean body mass and height than girls
What happens to body fat in preparation for adolescent growth spurt?
Increases! Changes in body fat are normal
What is self-efficacy?
Knowledge of what to do and ability to do it

From age 11…
