Chapter 5 Overview of Growth and Development
Introduction
Parents express concerns regarding children's growth and development.
Nurses play an essential role in reassuring parents and identifying developmental issues early.
Definition of Terms
Growth: Refers to an increase in physical size of a whole or parts and in the number and size of cells. Measurable and precise.
Development: A complex, continuous process leading to activities, motives for activities, and behavior patterns.
Stages of Growth and Development
Stages of Childhood Growth:
Newborn: Birth to 1 month
Infancy: 1 month–1 year
Toddlerhood: 1–3 years
Preschool age: 3–6 years
School age: 6–11 or 12 years
Parameters of Growth
Birth weight doubles by 6 months, triples by 1 year, and quadruples by 2 to 3 years.
Culture
Definition: Cultural norms, habits, beliefs, language, values influencing development.
Importance of recognizing family structures and values affecting children’s performance in assessments.
Culturally sensitive tools and studies are being developed to gather accurate data for diverse populations.
Nutrition
Constant growth necessitates ongoing nutrient supply; both overall nutrition and specific micronutrients are crucial.
Children require more nutrients relative to their size compared to adults.
Dietary patterns can predict obesity risk: prevalence of obesity in U.S. children is 18.5% (as per NCHS, 2018).
Major Nutritional Factors of Concern (CDC, 2020b)
Inappropriate marketing of unhealthy food
Decreased access to affordable nutritious foods
Ready availability of unhealthy beverages
Lack of safe play and exercise areas.
Challenges in parental control over children's diets due to meals eaten away from home.
Health Status
Health status affects growth and development; diseases can impair nutrient delivery, hormone regulation, and organ function.
Diseases impacting growth include digestive disorders, respiratory illnesses, heart defects, and metabolic diseases.
Piaget’s and Erikson's Theories of Development
Piaget's Stages of Cognitive Development
Sensorimotor Period (Birth-2 years): Reflexive behavior adapts to environment; egocentrism; development of object permanence.
Preoperational Thought (2-7 years): Egocentric thinking; magical thinking; perception dominance.
Concrete Operations (7-11 years): Systematic, logical thinking requiring concrete objects.
Freud's Stages of Psychosexual Development
Oral Stage: Focus on mouth, sensory exploration via oral means.
Anal Stage: Focus on anus; control of bodily functions.
Phallic or Oedipal/Electra Stage: Genital focus; development of conscience and feelings of guilt.
Latency Stage: Repressed sexual feelings; calm period.
Erikson's Stages of Psychosocial Development
Trust vs. Mistrust: Infant learns goodness of self/world through reliable care; characterized by hope.
Autonomy vs. Shame and Doubt: Control of self, body; characterized by will.
Initiative vs. Guilt: Development of competitive behavior; characterized by purpose.
Industry vs. Inferiority: Mastery of skills; characterized by competence.
Kohlberg's Stages of Moral Development
Stage 0 (0-2 years): Naïveté and egocentrism; no moral awareness.
Stage 1 (2-3 years): Punishment-Obedience Orientation; right/wrong based on consequences.
Stage 2 (4-7 years): Instrumental Hedonism; actions based on self-interest.
Stage 3 (7-10 years): Good-Boy/Good-Girl Orientation; morality tied to social acceptance.
Stage 4 (10-12 years): Law and Order Orientation; respect for authority and rules.
Assessment of Growth
Standardized growth charts for comparison of a child's growth metrics against statistical norms.
NCHS growth charts for ages 2-20 years and World Health Organization charts for infants and children under 2.
Key metrics: Length/height, weight, head circumference, BMI.
Recognition of Abnormal Growth Patterns
Early detection and treatment of growth disorders leads to better long-term outcomes.
Assessment of Development
Developmental surveillance occurs at well visits during infancy and early childhood.
Formal developmental screenings at 9, 18, and 30 months are recommended for early identification.
Types of Play
Solitary play: Child plays alone.
Parallel play: Side-by-side play with lack of interaction (common in toddlers).
Associative play: Group play without goals.
Cooperative play: Structured group play with defined goals and leadership.
Onlooker play: Child observes peers.
Dramatic play: Role-playing various experiences.
Familiarization play: Handling healthcare materials in a safe environment.
Functions of Play
Contributes to physical, cognitive, emotional, and social development.
Enhances problem-solving, language skills, and communication through engagement in play activities.
Immunizations
Active vs. Passive Immunity
Live or attenuated vaccines: e.g., MMR, chickenpox, rotavirus, influenza.
Immunocompromised children should NOT receive live vaccines.
Preventing Vaccine Reactions
Assessing allergies and prior reactions essential before administration.
Awareness of potential adverse reactions like fever or local irritation post-vaccination.
Informed Consent
National Childhood Vaccine Injury Act mandates discussions on vaccine risks and benefits prior to immunization.
Barriers to Immunization
Complexity of healthcare system may lead to confusion.
Various other barriers including access and parental misconceptions about vaccines.
Administration of Vaccines
Injection sites vary by age; deltoid for children over 18 months, anterolateral thigh for younger.
Proper documentation for each vaccine is crucial.
Special Considerations Related to Immunizations
Precautions needed for immunocompromised children.
Knowledge of what conditions do not contraindicate vaccine administration.
Education
Immunization as a critical healthcare component; parents should be given clear information regarding vaccination schedules and potential barriers.
Key Dietary Recommendations
Infants: Exclusive breastfeeding for 6–12 months.
Children: Continue whole grain and limit juice intake.
Specific daily servings of dairy products necessary by age group.
Cultural and Religious Influences on Diet
Nurses need to understand dietary customs impacting children's nutrition during assessments.
Assessment of Nutritional Status
Components include anthropometric, biochemical, clinical examination, and dietary history data.
Identifying at-risk children for prevention through evaluation and follow-up is important.
Activity Recommendations
Children older than 6 years should engage in moderate to vigorous physical activity for at least 60 minutes daily.
Safety Practices
Motor vehicle safety crucial for older children; drowning prevention for younger ones.
Nurses should model safety practices and offer educational support on preventing injuries.
Conclusion: Key Concepts
Growth, development, maturation, and learning are interrelated processes.
Variations within normal limits occur during growth.
Weight, height, head circumference should be regularly monitored.
Early interventions for delays improve outcomes.
Genetics, environment, nutrition, health, and culture significantly impact growth and development.
Understanding developmental theories and play is vital for fostering healthy growth and development in children.
Proper immunization practices are essential for preventing infectious diseases.
Nutritional needs encompass a multi-faceted approach, emphasizing the need for a balanced diet rich in essential nutrients.
