traditional definition of growth
limited to PHYSICAL maturation
A more appropriate definition includes FUNCTIONAL maturation
An increase in number and size of cells as they divide and synthesize new proteins
Results in increased size and weight of the whole or any of its parts
Growth
Percentile of growth is a statistical representation of 100 children and placement within the 100 members of comparison group
Percentiles of growth
A gradual change and expansion
Advancement from a lower to a more advanced stage of complexity
Increased capacity through growth, maturation, and learning
Development
“head to tail”
Cephalocaudal
“center to periphery”
Proximodistal
Periods of Growth-Infancy
Most rapid
Periods of Growth-Preschool to puberty
Rate of growth slows
Periods of Growth-Puberty
Postpuberty
Decline in rate of growth
Until death
Factors Influencing Growth
Heredity
Nutrition
Gender
Disease
Environment:
Hazards
Socioeconomic influences
Season, climate, and oxygen concentration
Physical growth potential—height, weight, body shape, features
HEREDITY
NUTRITION
Largest single influence on growth
positively correlates with diminished height, weight, and IQ in later life
Severe malnutrition during critical periods of development (e.g., 0-6 months)
Influences are different; different growth charts; onset of puberty; full adult size attained earlier in girls
GENDER
Skeletal disorders—dwarfism, chromosome anomalies, disorders of metabolism and poor absorption of nutrients
Chronic disease leading to chronic (even subacute) hypoxia—small, short stature, poor growth patterns
Examples: Cystic fibrosis, respiratory diseases, cardiac lesions
DISEASE
Carcinogens (e.g., Love Canal, Chernobyl), chemicals, radiation
Unsafe environment»_space; Injuries
Passive inhalation of tobacco smoke
Polluted water, air, food
ENVIRONMENTAL
Higher socioeconomic status (SES) = healthier overall
Availability of good nutrition, especially protein sources
Hazardous environments (e.g., unsafe neighborhoods)
Education—difficult to quantify but affects outcome at some level
SOCIOECONOMIC INFLUENCES:
Children appear to grow in HEIGHT faster in spring and summer; gain weight in fall and winter
Hormonal? Or activity related?
Sunny climate—ultraviolet damage to skin and eyes
Chronic hypoxia—also children in high altitudes generally smaller than those at lower altitudes
SEASON, CLIMATE, OXYGEN:
Heredity and environment
Gender differences vs. cultural expectations
Disease
Prenatal influences
Socioeconomic status
Interpersonal relationships
Stress
Television and mass media
Factors Influencing Development
Heredity and environment BOTH affect
development,
Aggressive play in boys; verbal aggression in girls—even at VERY young ages and in solo play
Imitation and modeling vs. inherent developmental-behavioral differences
For preschoolers playing with dolls, nurturing no different among genders; at ages 6-10 girls become more nurturing
Gender behaviors in children
Disease effect on development
regressive behavior
chronic inner stress
Prolonged state of disequilibrium
Passive smoke, alcohol exposure, other substances such as RXs, illicit drugs, and poor maternal nutrition»_space; poor pregnancy weight gain»_space; IUGR
Prematurity as major influence on neonatal and infant development
PRENATAL INFLUENCES
Influences on development may be perceived as “judgmental” but are historically evident
When children with same disease or disorder are compared, higher SES will have higher developmental outcome
SES
Parents, siblings, extended family members
Need for love and affection—SAFETY and security needs
Discipline and authority
Dependence-independence
Emotional deprivation
INTERPERSONAL RELATIONSHIPS
Stress of hospitalization
Fears of childhood
STRESS in childhood
Identification with behaviors and/or characters indicative of immaturity and possibly mimicking behaviors
Repeated exposure in media»_space; alters view of “normal” behavior and human interaction
TV and Internet»_space; physical inactivity»_space; childhood obesity, childhood depression
TV and mass media
