Growth and Development in Adolescence

• Course Title: "Health Promotion of the Adolescent and Family," 1402301
• Instructor: Dr. Rawnaq Almahadeen
• Institution: Mutah University, Faculty of Nursing

Learning Objectives

• Discuss biological development
• Identify personality and cognitive development
• State the development of social development and body image
• Describe optimal health during adolescence, including: nutrition, sleep, dental health, mental health, safety promotion, and injury prevention

Puberty

• Puberty is a maturational, hormonal, and growth process
• It occurs when reproductive organs start functioning and secondary sex characteristics develop
• Prepubescence: 2-year period before puberty, with preliminary physical changes leading to sexual maturity
• Puberty: Point of sexual maturity, marked by first menstrual flow (girls) or other indicators (boys)
• Postpubescence: 1-2 years after puberty, where skeletal growth completes and reproductive functions are established

The "Ages" of Adolescence

• Adolescence encompasses psychological, social, and maturational processes initiated by puberty
• Adolescence is divided into three subphases:
  • Early adolescence (11-14 years)
  • Middle adolescence (15-17 years)
  • Late adolescence (18-20 years)
• Teenage years are synonymous with adolescence

Biological Development

• Puberty's physical changes result from hormonal activity regulated by the anterior pituitary gland and hypothalamus
• Puberty leads to increased physical growth and secondary sex characteristics (voice changes, hair growth, fat deposits)
• Biological changes during puberty include:
  • Sexual maturation
  • Height and weight increase
  • Skeletal growth completion and body mass changes

Sexual Maturation (Girl/Boy)

• Girl*
• Thelarche (breast buds): First sign (8-13 years)
• Rapid height and weight increase
• Pubic hair growth (Adrenarche) 2-6 months after thelarche
• Axillary hair appearance
• Menarche (menstruation) 2 years after first pubescent changes
• Boy*
• Testicular enlargement and scrotal color change: First signs
• Puberty usually occurs between 9-14 years
• Pubic hair growth
• Axillary and facial hair development
• Spermarche (sperm production): Around age 14

Other Physiological Changes

• Puberty alters various physiological functions, including increasing heart size, blood volume, and systolic blood pressure, while decreasing heart rate
• Girls begin growth spurt earlier (9.5-14.5 years) than boys (10.5-16 years)
• Average height gain (boys: 10-30 cm, 7-30 kg; girls: 5-20 cm, 7-25 kg)

Personality, Cognitive, and Moral Development Theories

• This section outlines various psychological theories relevant to adolescent development, including Freud's psychosexual theory, Erickson's psychosocial theory, Piaget's cognitive theory, and Kohlberg's moral judgment theory

Psychosocial Development (Erikson)

• Identity formation - developing a stable self-image encompassing past and present experiences, with an understanding of future goals
• Identity vs. Role Confusion:
  • Adolescents experience physical and emotional changes, navigating the transition from high school to adulthood
  • Adolescents face crisis, striving for personal identity while seeking autonomy from family
  • Developing a personal identity depends on resolving relationships within the peer group.

Cognitive Development (Piaget)

• Formal operational thought (Piaget's last stage): Beyond concrete thinking, adolescents consider possibilities, engage in logical reasoning, and mentally manipulate multiple variables

Social Development

• The social environment (family, peers, school, community) influences adolescent development and health
• Families: Conflicts can arise regarding autonomy, privileges, and personal expectations. Favorite topics of debate include substance use of any kind, cell phone use, hairstyles, and other privileges.
• Peers: Teens seek acceptance by adopting peer group norms (dress, mannerisms), gaining from collective support, and forming their own identity
• Peers are vital information sources, role models, and reinforcement mechanisms for social behavior

Development of Body Image

• Physical changes during early adolescence can cause confusion
• Hormonal influences (e.g., acne) create body image concerns
• Teenagers compare themselves to peers and media images
• Puberty evokes varying reactions between girls and boys

Promoting Optimal Health during Adolescence

• Nutrition: Puberty's accelerated growth leads to increased nutritional needs (calories, protein, calcium, iron, zinc)
• Adolescents face challenges with diet, potentially leading to overeating, unhealthy food choices, or insufficient nutrients
• Sleep: Adolescents require 9 hours of sleep nightly, but schedules often interfere, which affects their health and well-being
• Dental Health: Consistent dental care is essential. Regular dental supervision is vital
• Mental Health: Adolescents encounter stressors including body image, sexuality, academics, peer pressures, relationships, finances, and career aspirations
• Safety Promotion and Injury Prevention: Physical injuries are the leading cause of death in this age group, with motor vehicle accidents, sports injuries, and accidental shootings among the most common causes
• Education: Effective health promotion needs a developmentally appropriate, inclusive approach with input from adolescents. Privacy is crucial
