Unintended Pregnancy“All pregnancies should be intended-that is, they should be consciously and clearly desired at the time of conception.”- IOM Committee on Unintended Pregnancy Perinatal Forum May 17, 2004
Intendedness question Thinking back to just before you were pregnant, how did you feel about becoming pregnant? • You wanted to be pregnant sooner • You wanted to be pregnant later • You wanted to be pregnant then • You did not want to be pregnant then or any time in the future
Potential effects on response rates to intendedness question Individual-Level Effects • Misunderstand what is being asked • Language • Comprehension • Not able to answer • May refuse because question is intrusive • May refuse because suspicious of system Interviewer Effects • Not explain purpose of questions • Not ask question directly • Interviewer uncomfortable with question • Poor practices/ not following protocol
Response Categories • Women were defined as having “valid ” responses if they answered that their pregnancies were: • Wanted sooner • Wanted later • Wanted then • Not wanted at all • In addition, women were classified as “Don’t Know” if they indicated that they were unsure of their intentions at conception. • Finally, women were also classified as “Refused” if they refused the question, and “Missing” if no answer was recorded.
Refusing this question is associated with refusing other questions... 51% of the women who refused to answer the intendedness question refused to answer at least one the other questions
Most women who were missing this question were also missing the others... 98% of women missing the intendedness question also were missing the other questions
Implications Current ascertainment of unintended pregnancy may seriously underreport those groups with or at high risk for poor outcome, potentially diluting the observed associations between intendedness at conception and perinatal outcome.

Defining unintended pregnancy(from the IOM and NSFG) • Intended pregnancies • Wanted at the time of conception, regardless of use of contraception at the time. Women who indicate they wanted to be pregnant sooner, or at that time, are considered to have intended pregnancies. • Unintended pregnancies • Not wanted at the time conception occurred, regardless of contraception.
Defining unintended pregnancy • Unintended pregnancy categories • Unwanted pregnancies • Conception occurred when the woman did not want pregnancy at any time in the future. • Mistimed pregnancies • Conception occurred at a time when the woman did not plan to become pregnant, although she may have planned to do so in the future
Data Sources for Unintended Pregnancy Information • National Survey of Family Growth (US) • Pregnancy Risk Assessment Monitoring System (PRAMS) Project (NYS) • Regional Perinatal Data System (FLR) • NYS Vital Statistics - induced abortions

What is the basis for considering unintended pregnancy one of our leading public health problems? • Magnitude/ frequency of occurrence • Breadth of populations affected • Association with significant maternal and child morbidity • Costs to the public/private health care system • Sensitivity to primary prevention

Healthy People 2010 Objective 9.1: “Increase to 70% the proportion of pregnancies that are intended.”
Progress Toward Healthy People 2010 Objective 9.1: In 2000 in the Finger Lakes region, 54% of pregnancies were intended.
Pregnancy Intention in the United States, 1995 15.5% of pregnancies were mistimed and resulted in a live birth 25.1% of pregnancies were mistimed and unwanted and resulted in abortion 7.6% of pregnancies were unwanted and resulted in a live birth 51.7% of pregnancies were intended and resulted in live birth
Pregnancy intention in New York(not including NYC) , 1999 27.3% of pregnancies were mistimed and resulted in a live birth 20% of pregnancies were mistimed and unwanted and resulted in abortion 44.9% of pregnancies were intended and resulted in a live birth 7.8% of pregnancies were unwanted and resulted in a live birth
Intended and unintended pregnancies, FLR, 1999 14%ofpregnancies were mistimed and resulted in a live birth 20.9% of pregnancies were mistimed/ unwanted and resulted in abortion 4.6% of pregnancies were unwanted and resulted in a live birth 42.6% of pregnancies were Intended and resulted in a live birth

Women at risk for unintended pregnancy • Mistimed and unwanted pregnancies occurred in every demographic group (by age, race, education) • Younger women are at higher risk of mistimed pregnancies • Older women are at higher risk of unwanted pregnancies
The “average” woman with an unintended pregnancy which resulted in birth... • Was not a teenager • Was of white, non-Hispanic heritage • Had Medicaid coverage • Had at least one pregnancy prior to this one • Lived in a non-urban area
Outcomes Infants born to women whose pregnancies were unintended are more likely to be: • low birth weight, • delivered preterm, • not breast fed, • placed in foster care/adoption.

Public Health/Clinical Focus Through primary prevention, we are able to avoid the potentially disastrous effects and agonizing decisions that women with unintended pregnancies face
Implications of findings • Effect of unintended pregnancies on women’s lives? • Education • Employment • Family finances • Stress/ health • Cost of unintended pregnancy to society • Public funding now and in future • Child abuse/neglect
More information needed... • Barriers to effective contraception use • Methods that are reliable and acceptable • How to effectively address unintended pregnancy as a public health problem
Public Health/Clinical Focus Secondary and tertiary prevention of unintended pregnancy • Transition from unintended conception to intended birth • Particularly focus upon pregnancies unwanted at conception • Bonding interventions • Social support • Parenting education
