Study Notes

Overview of Adolescence

Adolescence lasts from ages 10 to 18, marked by puberty and transition to adulthood.
Hormonal changes during puberty foster physical and cognitive development.
Brain development contributes to increased risk-taking behaviors and improved abstract thinking.
Adolescents redefine relationships with parents, gaining more autonomy while navigating peer influences.
Identity formation involves exploration of various roles and ideological positions.

Growth Patterns

Puberty typically starts between ages 8 and 14; girls generally begin around age 10, boys two years later.
Physical growth spurt adds 10-11 inches in height and 50-75 pounds in weight; follows a specific sequence of growth in hands, arms, and torso.
Gender differences in height and weight emerge; girls are taller until age 14, after which boys tend to surpass in both height and weight.
Socially preferable body images often favor shorter women and taller men, leading to weight-related concerns among teens.

Sexual Development

Sexual maturation includes primary characteristics: male testes and sperm production; female ovaries and menstrual cycles.
Primary sexual characteristics develop between ages 11 to 15, impacting fertility.
Secondary sexual characteristics emerge, including broader shoulders for boys and breast development for girls.

Acne and Pubertal Changes

Acne affects approximately 85% of adolescents, exacerbated by hormonal fluctuations.
The age of puberty has shifted earlier, with girls starting menarche around age 13, compared to age 16 a century ago.
Early maturation in girls is linked with various mental health challenges, including anxiety and depression.

Brain Development

The adolescent brain matures with increased neural connections and specialized areas, although overall size remains constant.
Myelination enhances processing speed but decreases neurological plasticity.
The limbic system drives emotional responses and social interactions, while the prefrontal cortex, responsible for decision-making, continues to develop until the mid-20s.

Decision-Making and Risks

Adolescents take more risks due to heightened dopamine sensitivity, which enhances the response to social rewards.
Peer presence influences risky behaviors such as unsafe driving and substance use.
Mental illness onset occurs predominantly by age 14; repeated drug exposure can alter brain function.

Sleep Patterns and Risks

Adolescents require 8 to 10 hours of sleep, but many average only 7.5 hours due to societal demands and biological changes.
Sleep deprivation contributes to issues like irritability, poor academic performance, and risky behaviors.
Circadian shifts lead to later sleep times; most schools start before 8:30 AM, exacerbating sleep-related problems.

Sexual Activity and Trends

Increased sexual attraction typically begins by age 10 or 11; over half of high school students report having experienced sexual intercourse.
Adolescent pregnancy rates have declined significantly since the early 1990s, with a notable drop of 58% between 2007 and 2018.### Adolescent Sexual Activity and Pregnancy Risk
Recent trends indicate adolescents are less sexually active compared to previous years, with an increased use of birth control among sexually active individuals.
Factors reducing risk of adolescent pregnancy include close parent-child relationships, parental supervision, and strong parental values against unprotected intercourse.
Increased risk factors for adolescent pregnancy comprise disorganized neighborhoods, low socioeconomic status (SES), single-parent households, older sexually active siblings, early puberty, and history of sexual abuse.

Consequences of Adolescent Pregnancy

Only 40% of teenagers who give birth before 18 graduate from high school, impacting job prospects and economic independence.
Teenage mothers are often more likely to experience poverty, with over 75% relying on public assistance within five years of childbirth.
Approximately 64% of children born to unmarried teenage high school dropouts live in poverty.
Children of teenage mothers face a 50% higher likelihood of repeating grades, are more likely to underperform on standardized tests, and have an increased risk of high school dropout.

Parenting and Education Trends

Among fathers aged 22 to 44, 70% with less than a high school diploma fathered a child before 25, while only 14% of those with a bachelor’s degree did so.
Women with higher education levels generally have children at older ages.

Eating Disorders Overview

Eating disorders predominantly manifest during adolescence and young adulthood, affecting both genders but with higher prevalence among women.
Men can also experience distorted body image disorders, such as muscle dysmorphia.

Prevalence and Risk Factors for Eating Disorders

Eating disorders affect various racial and ethnic groups similarly, though anorexia nervosa is more common among Non-Hispanic Whites.
Genetic, biological, psychological, and social factors contribute to the development of eating disorders, often running in families.
Research identifies overlapping genetic factors for anorexia with traits related to metabolism and physical activity.

Types of Eating Disorders

Anorexia Nervosa: Characterized by self-imposed starvation, intense fear of weight gain, and distorted self-evaluation regarding body weight.
Bulimia Nervosa: Involves recurrent binge eating followed by compensatory behaviors like purging or excessive exercise, with significant self-evaluation influenced by body shape.
Binge-Eating Disorder: Recurrent binge eating marked by distress, without inappropriate compensatory measures.

Health Consequences of Eating Disorders

Anorexia leads to severe health issues, including heart problems, osteoporosis, muscle loss, dehydration, fatigue, and has the highest mortality rate among psychiatric disorders.
Bulimia can result in digestive issues and serious health complications, including esophageal damage and tooth decay due to frequent vomiting.
Binge eating disorder is associated with obesity-related health risks, including heart disease and Type II diabetes.

Treatment for Eating Disorders

Effective treatment requires nutritional stabilization and cessation of harmful behaviors, tailored to individual needs.
Treatments may include medical support, nutritional counseling, medication (like antidepressants), and psychotherapy (individual, group, family).
The Maudsley Approach emphasizes family involvement in recovery efforts.

Cognitive Development: Piaget’s Formal Operational Stage

In the formal operational stage, adolescents can contemplate abstract concepts like beauty, love, and morality.
Shift from trial-and-error problem solving to hypothetical-deductive reasoning facilitates systematic testing of possibilities.
Adolescents are capable of engaging in genuine scientific thinking and accepting hypothetical scenarios.
