  1. Teen health

  2. What happened to that sweet child • Major changes in the brain and body of teens that equip them for the passage to adulthood • Beginning to handle complex information and make decisions • Starting to handle more complex emotions and to control behavior • Risk takers as they understand their place in the world • Impulse control is not mature • Strive for independence • Judgment is still mostly primordial and reactive • Change from family to peer group as major source of socialization • Emotional maturity is still forming

  3. Diet and exercise

  4. obesity

  5. sleep • 45% of adolescents are sleep deprived <9 hours • Onset of puberty is coincident with a shift in circadian rhythm and results in a time delay for sleep • Strong affects of hormones on these rhythms • Starts in girls around 8 and boys around 10, but peaks in puberty • There is decreased sleep pressure and a lengthening of the circadian cycle

  6. Affects of sleep deprivation • Heightened/exaggerated worry • Increased susceptibility to anxiety • Linked to depression and suicidal ideation • Poor school performance • Increases weight • Increased incidence of driving accidents • Sleep disorders

  7. Sexual behavior • 50% report sexual activity: 16% with >one partner • Many unprotected • Increased use of condoms since 2002 • Up to 70-80% of males at first encounter • Non-hormonal BC is also on the rise with 8% of girls • Overall 75% females and 85% males are employing some form of protection • Sexting is a modern invention • 13% of HS kids receive sexts; boys>girls • 10% have sent them • Linked to depressive behaviors • Linked to non-heterosexual orientation • Hook-ups also a modern form of sex

  8. Drugs and alcohol • 75% of teens drink or have tried drinking • 50% had someone else get it for them • 25% had >5 drinks • 25% drank before sex • 28% rode in a car with driver who had been drinking • 10% had driven after drinking • 36% have used marijuana • 5-10% other drugs

  10. The teen brain • Major growth • Particularly in the frontal cortex • Higher function/reasoning-CEO • setting priorities, organizing plans and ideas, forming strategies, controlling impulses, and allocating attention • Socialization • Significant growth in neurons in pre-adolescence with a use-it or lose-it maturation process thereafter • Increase in dopamine receptors • Mechanism for mature judgment and impulse control • Reward system, this is where the behavior-reward system matures • Increase in neuronal connections • Allows for parallel parts of the brain to communicate for enhanced and more intricate learning and ability to handle more difficult information and emotions

  11. Everything is in process • Most areas are not mature until the late 20s • Response to stimuli is not based in judgment but is more based in fear (impulsive) • Ability to determine outcomes both emotional and rational are very difficult • Actions such as pregnancy are not projected into the future

  12. Support the change • Brain is well suited to handle the changes of adolescence • Since the link between positive experiences and behaviors is so strong at this stage, adolescents can contribute to their own growth • What about parents/other adults/institutions • They need safe environments and guidance from adults • How can adolescents make mistakes and recover • Studies show that resilience is one of the key factors that predicts happiness and sucess • How do adults and institutions support the adolescent so that at the end they are well adjusted, competent, confident adults

  13. Parent’s role is changing • Teens do not readily share with adults naturally • Need to provide modes for this to occur • Be non-judgmental • This is a time of heightened sensitivity about who they are, you will loose them if you are not open • Set expectations and discuss consequences • Support them is they fall short • Allow them to take chances and make mistakes • Lead by example they are watching

  14. On-set of some diseases • Eating disorders • Sleep disorders • Autoimmune disease • Psychological disorders • Asthma • Sex related issues • Infections • 25% of STDs are in teens • Abnormal PAP smears • Teens are more likely to have abnormalities, are very vulnerable

  15. Physician visit • State your concerns at the beginning of the visit and then leave • This is your child’s time to establish a bond and a safe place to share difficult issues • If they find their confidence has been broken they will not share • You can still be part of the process, and will be asked to consent for medical issues, ie vaccines, tests, etc.

  16. pertussis

  17. Neisseria Meningitidis • Highest incidence of disease < 5 yr • Case-fatality rate is highest in adolescents ( 20%). • Increased risk among college freshman living in dormitories. • At least 75% of cases in 11- to 18-year-olds are caused by serogroups A, C, Y, and W-135 • 50% of cases in infants caused by serogroup B- no vaccine for serotype B

  18. Neisseria Meningitidis-vaccines • Conjugated tetravalent vaccine (Menactra-MCV4) • Licensed by FDA 1.05 • Contains serogroups A, C, Y, and W-135 • Elicits strong T-cell dependent responses that induce memory

  19. GARDASIL® (Quadrivalent Human Papillomavirus [HPV Types 6, 11, 16, 18] Recombinant Vaccine) US HPV Infection Statistics • HPV is the most common STD in young sexually active individuals • In sexually active individuals 15–24 years of age, ~9.2 million are currently infected.3 • An estimated 74% of new HPV infections occur in this age group.3 • Lifetime risk for sexually active men and women is at least 50%.1 • By 50 years of age, at least 80% of women will have acquired genital HPV infection.1 1.
