1. Evaluation of the Pregnancy Risk Assessment Monitoring System (PRAMS) as a Surveillance System for Pregnancy Intention By: Olivia Sappenfield, MPH Office of Data Translation Bureau of Family Health and Nutrition Massachusetts Department of Public Health

2. Unintended Pregnancy All pregnancies wanted later or not at all Association with poor birth outcomes including preterm birth, low birth weight (LBW), and small for gestational age (SGA) 1-4 Association with delayed and inadequate prenatal care, continued drinking, continued smoking during pregnancy 1-4 Represent about ½ of all births nationally Cost more than $9 billion annually 5,6 Risk Factors Maternal race/ethnicity, maternal age, maternal education, household income, marital status Partner’s intention, desirability of partner, number of partners, contraceptive use

3. Pregnancy Intention in Massachusetts State and Title V priority: “Support reproductive and sexual health by improving access to education and services” State priority measure: “The percentage of pregnancies among women age 18 and over that are intended ” Traditionally reported using Behavioral Risk Factor Surveillance System (BRFSS) Pregnancy intention asked every other year Queries about pregnancies up to 5 years ago PRAMS offers a valuable alternative Data used to inform the Title V Block Grant and reports Queries about pre-pregnancy contraceptive use

4. PRAMS Population-based data on maternal attitudes and behaviors before, during, and shortly after pregnancy Sampled from birth certificate file Data collection began in 2007 80 questions (54 core, 16 standard, and 10 MA- specific) Includes a mail and phone phase Administered 2-6 months postpartum English and Spanish surveys only

5. Methods Adapted CDC’s “Updated guidelines for evaluating public health surveillance systems” Initially developed for infectious disease surveillance systems PRAMS stakeholder surveys Usefulness and acceptability of PRAMS to monitor pregnancy intention PRAMS staff surveys Analytical comparison of BRFSS and PRAMS Dependent variable: pregnancy intention Independent variables: maternal age, maternal race/ethnicity, maternal education, marital status, and household income

6. Methods Continued Pregnancy intention definition: Unintended: wanted later or not at all Intended: wanted then or sooner PRAMS question: Thinking back to just before you got pregnant with your new baby, how did you feel about becoming pregnant? BRFSS questions: 1) Have you been pregnant in the last 5 years 2) Thinking back to your last pregnancy, just before you got pregnant, how did you feel about becoming pregnant? Chi-square tests to determine similarity of population from year to year Inability to link data to assess sensitivity and PPV Confidence interval overlap, means no significant difference

14. Other Attributes Flexibility PRAMS conducted annually States able to include state-specific questions CDC changes to core questions (Phases) Can adapt to add questions on emerging issues (e.g. H1N1) Timeliness 2-6 months postpartum vs. up to 5 years postpartum Women surveyed postpartum – recall bias Data Quality Response rate consistently above 65% Question response rate between 97.5% and 95% Representativeness Population-based, oversamples by race/ethnicity Deliveries ending in live birth Other Attributes: Simplicity, Acceptability, and Stability

15. Conclusion: PRAMS is an Acceptable System for Monitoring Pregnancy Intention Considered an acceptable data source by researchers and by its study population Timely surveillance system for state-level data on postpartum women Prevalence of unintended pregnancy overlapped for all indicators except <185%FPL and certain subgroups (married, some college education, and NHW) Concern because poorer women are more at risk of unintended pregnancy Similarly represented less educated women and minority women, who are also more at risk Can provide estimates for the magnitude of morbidity associated with pregnancy intention Inform reproductive health programs Inform reproductive health programs Used in home-visiting programs to assist in developing reproductive life plans Used in home-visiting programs to assist in developing reproductive life plans

16. Strengths and Limitations of PRAMS Retrospectively collects data-recall bias Collects data soon after delivery Capable of detecting trends that signal changes in pregnancy intention Currently no “partner questions” Ability to change PRAMS questions every year Does not collect data on fetal death, spontaneous abortion, or induced abortion Live births used for family planning programs Live births used for population contraceptive need
