Foundation in health studies- HLTB03 Lecture 7- Child health: overall child death rates have been steadily declining. But places like in Sub-Saharan Africa it is still very high. 43% of deaths of children under five years old occurred in Africa. Mostly from: AIDS/HIV, malaria, respiratory and bacterial infections, diarrheal and traffic accidents. MAIN: Pneumonia. Acute respiratory disease and childhood diarrhea. Infant birth weight; Canada: lower than most countries. But • Due to international differences: the cut off points/ standardized criteria are different from country to country. (LIMITATIONs of cultural differences) • Children born, even though not still born • A lot of multiple births: many women are waiting till later to have children. Risk factor for low birth weight. Childhood obesity in Canada: rates have tripled in the last 25 years. Approx. 26% of Canadian children ages 2-17 years old are currently overweight or obese. 1/3 of normal weight 20 year olds, will move into the overweight category; the other 1/3 will become obese. (Both within 8 years) Risk Factors: • High sugar and fat drinks and foods • Not physically active each day (playing video games vs. going out and playing) • Eat to deal with stress or problems • Lack of resources or family background that favors healthy eating habits • Genetic disease or hormone disorder such as Prader-Willi syndrome or Cushing’s syndrome. Prevention: • 5 fruits and vegetables per day • 2 hours of screen time or less per day • 1 hour of physical activity per day • 0 sugar sweetened beverage per day Fetal development: • 6 weeks: heart • 9 weeks: spine formed • 10 weeks: almost all organs completely formed • 15 weeks: sex of child determined: fetus can hear, fingers can grasp • 20 weeks: placental fully formed • 28 weeks: eyes completely formed • 30 weeks: lungs are only major organ left to develop complete (in boys there is a tendency for lungs to develop slower- problem for premature babies) • 42 weeks: baby overdue • Bones in skull not hardening as much as other bones: and synapses and neurons are developing. Also mothers hormones and anti-bodies are being shared Theory in child development: Psychoanalytic, Learning, Piagets cognitive-development and Ethological theory. Psychoanalytic theory: Oldest and most controversial development theory. Inner forces outside the awareness. Freudian Slip: subconsciously calling a girl by your mother’s name. • The conscious mind: memory, things we are aware of. • The unconscious mind: feelings and thoughts outside of the consciousness. Continues to influence our behavior, even if we are unaware. o Id: consistently there. Unconscious o Ego: dealing with reality. Operates on the REALITY PRINCIPLE: aims to satisfy the Ids desires in a socially acceptable way o Super ego: moral rules. Begins at age 5. Eric EriksonPsychosocial theory: emphasized family, cultural on the development of the personality throughout the lifespan. Stage Ages Basic Important Conflict Event 1.

Maturity 65 to death Ego Integrity vs. Despair Reflection on and acceptance of one's life Critique of Psychoanalytic theory: • Relies on individual case studies limiting generalizability • Overly negative view of development & overemphasis on the importance of early sexuality in personality development • Emphasis on the importance of early experience in personality development: Freud didn’t really include on that. • Greatly expanded our perspective on child development Learning theory: • John Watson (1878-1958) • Behaviorism - focus on behavior: stimulus response. Associated with conditioning. • Albert and the rat: Albert was not scared of the rat.
