Iron Deficiency & Anemia • What is anemia? • Symptoms: • Fatigue / weakness • Pale skin • Rapid heartbeat • Irritability • Decreased appetite • Dizziness / Lightheadedness
Preventing Anemia • Foods rich in iron • Red meat, tuna, salmon, eggs, enriched grains, leafy green vegetables, fortified foods • May need a supplement • Recommended amounts: • 7-10 mg/day for children 1-12 years old • 11 mg/day for adolescent boys; 15 mg/day for girls
Teenagers and Calcium • Teenagers need calcium to build strong bones • Calcium is also important for muscle contractions • The osteoporosis connection… • Why talk about this in a child & adolescent health class??
Osteoporosis • 1 of every 2 American women will get osteoporosis after the age of 65. • Why worry about teenagers? • Less than half of teenagers get enough calcium in their diet. • For girls – about 15% get enough calcium. • The teenage years are the time to build strong bones
Soda consumption & Osteoporosis • Girls who drank soft drinks: 3x more likely to have a bone fracture • Physically active girls: 5x more likely to have a bone fracture • Why? • Phosphoric acid • Less calcium consumption • Source: Harvard School of Public Health

“Selling” it to teenagers • Make it beneficial in the short term • May need to relate it to body image • “Calcium will help you grow taller” • “Do you know those older people that are stooped over?” • Low-fat, non-fat alternatives for those worried about gaining weight.
Teenagers & Dieting • Over ½ of teenage girls and 1/3 of teen boys use unhealthy weight control behaviors. • (Neumark-Sztainer, 2005) • These behaviors include: • Skipping meals • Fasting • Smoking cigarettes to control weight • Vomiting • Taking laxatives
