How has the rate of adolescent pregnancy in the US changed over the last 10 years?
Historic lows in all racial and socioeconomic statuses - since the 1950s
What are some of the factors that have contributed to decline in ado pregnancy?
- Primarily due to improvements in contraception use
- Increased use of highly effective and dual contraception methods
- Comprehensive sex education programs
- Access to contraception
- Changes in childbearing norms – used to be cool
- Little of the change due to delaying sex – age of first sexual experience has not changed
What are some of the factors that place teens at greater risk for adolescent pregnancy?
- Age of first sex before 15years
- No contraception use at 1st sexual encounter
- Older partners (3 years)
- Greater number of sexual partners (3 or more)
- Poverty – missed results
- Inconsistent contraception
- Previous pregnancy – biggest red flag.
- 25% have a 2nd child within 24 months
- Poor school performance
- Pregnancy wantedness/ambivalence
Pregnancy and contraceptive outcomes for teens who desire pregnancy vs those who are ambivalent
similar. Ambivalent are
- Less likely to use contraception
- More likely to be pregnant within 6 months
- Higher risk of STIs because of inconsistent condom use
Why do teens want to use home UPTs
- Privacy, confidentiality, immediate results
- Cost of test vs cost of clinic or office visit
- Access to care and insurance coverage or lack of insurance privacy for teen
What does use of a HPT indicate about a teen?
- red flag for pregnancy ambivalence - high risk of getting pregnant later. Ask if they’ve ever done.
Why is teen use of HPTs problematic?
- Less likely to perform tests accurately and at optimal time
- False negative tests related to delay in seeking care
- Missing a large number of teens who are in need of care for contraception, STI screening, etc
When are HPTs most accurate?
1 week after first day of missed menses
(Early tests” can pick up 25-50 mIU/ml of HCG [first day of missed menses] )
What factors contribute to false negatives on an HPT?
- may be more prevalent with adolescents
- too early & HCG levels not high enough to be detected
- dilute urine (best to use first morning void)
- timing of color change; directions not followed
Consequences of a false negative in ados
- delay seeking care or repeating test
- limits pregnancy options or behavior changes
- ectopic pregnancy or threatened /missed abortion
False negative rate in ado HPTs
24-48 % or greater rates
Why might an HPT be a false positive?
(rare); tumors, LH surge with ovulation
What should you do if an ado is using HPTs?
- Discuss how they work and when will be most accurate; follow directions exactly
- Arranging a follow-up visit to validate results - insurance and privacy may be a concern
- Arrange visit for plan of care regarding results and STI screening
- Contraceptive counseling, including emergency contraception
- Work with manufacturers’ help-lines and written package directions to make teen-friendly
Why would you do a UPT in the office?
- Had unprotected sex and “want to be sure”
- Confirm home pregnancy test
- Offer test for late, missed, or undetermined period or last period was different from the others
- Hidden agenda visit
- Mother of teen request test
Signs of pregnancy on exam
- Enlarged uterus
- Breast changes/tenderness
- Softening and enlargement of cervix (Hegar sign)
- Bluish discoloration of cervix (Chadwick sign)
What to discuss with ado before UPT
- Determine need for test
- What she hopes the result will be
- Who knows she is getting a pregnancy test
- Will she share the results with parent/guardian and partner why or why not
- What does her partner hope the result will be
- Assess knowledge about options for positive and negative test
- Discuss contraception options
What do you as a clinician need to do if the result of the ado’s UPT is negative?
- Give results and observe reaction
- Assess pregnancy wantedness and readiness to use contraception – avoid telling them directly it’s a bad idea if they want it. Meet at their level to lead to understand consequences
- Match readiness
- Frequent follow-up
- Does she need another test in two weeks? Return in 2 weeks.
- STI testing
- Return in 2 weeks
Significance of negative pregnancy test for teen’s future pregnany risk
Significant risk of pregnancy in next 18 months
What to do if teen’s UPT is positive
“Your pregnancy test is positive that means that you are pregnant”
Accurate and unbiased discussion about her options
