Overview
Postpartum period as window of opportunity
Reduce chronic disease risk Benefit reproductive health
Education model Expanded Food and
Nutrition Education Program (EFNEP)
Improve diet and activity patterns
Address social context of low income women
Design
Recruit from USDA Special Supplemental Food Program for Women, Infant and Children (WIC)
Randomize to Usual WIC Care; Usual WIC Care + Enhanced EFNEP
12-mo intervention, 6-mo maintenance
Research Design
• Randomized, controlled trial N=680 WIC participants
Two conditions: Usual WIC Care Usual WIC + Enhanced EFNEP
• Enhanced EFNEP intervention 5 home visits 4 group classes motivational phone calls monthly
Outcome Measures
• Assessed at 2-6 weeks and 12 months postpartum
• Primary Outcomes fruit/vegetable intake saturated fat intake moderate-to-vigorous physical activity
• Secondary Outcomes Body Mass Index (BMII, wt (kg)/ (ht (m))2) Fat mass and distribution (TSF, waist)
Data Collection
Anthropometry• BMI• Mid-arm and waist circumference• Triceps skinfold
Survey Interview • 61-item food frequency questionnaire (Willett 1985)• Stanford 7-day physical activity recall• Mediating and modifying mechanisms
Major Hypotheses
• Improvements in primary outcomes will be greater at 12 mo postpartum among participants in Enhanced EFNEP, compared with Usual WIC Care
Increased fruit and vegetable servings Decreased saturated fat consumption Increased total moderate-to-vigorous physical
activity
• Decreases in (BMI) and indicators of fat mass and distribution will be larger among participants in Enhanced EFNEP, compared with Usual WIC Care
Ancillary Study
• Purpose Independent measure of change in minutes of daily moderate-
to-vigorous activity Document validity of reported duration and intensity
of mod/vig activity in low-income, multi-ethnic women Compare diet and activity self-reports with repeat recalls
• Design N=150 participants (75 in each condition) Baseline, 12, 18 mo Test measures: NIH diet screeners; 7dPAR Comparison measures:
7-days accelerometer Daily activity records (12 mo) 3 24-hr diet and activity recalls
Just for You: Status
January 2003679 women recruited, 131 ancillary participants.
Intensive field work requires increased staffing.
Group class component dropped; social support incorporated into home visits
January 2004: follow-up complete
Population Characteristics at Baseline (n = 679)
• Low-income (<185% of federal poverty)• Mean age = 27 years• More than two-thirds (69%) have twelve or fewer years of
education• One-third (34%) are not high school graduates • Three-quarters (75%) are Latina/Hispanic, 15% white, 8%
African-American, 1% other• Almost two-thirds (64%) report Spanish as native
language, as well as language typically spoken at home (60%)
• Majority of Latinas are immigrants with average time in U.S. of eight years
IMPLEMENTATION
Intervention components Intervention messages
Why Postpartum Health?
Health Centers defined need for greater understanding
Successful programs in prenatal and infant care
Postpartum care poorly understood, poorly executed
Window of opportunity for intervention:woman’s health, child’s health, “pre-conceptual care”
Intervention Components
• Usual WIC Care WIC vouchers and nutrition education Certification at 2-6 wk, re-certification 12 and 18 mo Anthropometry
• Enhanced EFNEP: Usual WIC Care PLUS Home visits
• In-depth assessment, action plan and goals Group classes
• Interactive discussion, cooking and activity Telephone counseling
• Reinforce goals, support, refer, check medical concerns
Intervention MessagesIntervention Messages
Physical activityPhysical activity

• Limit red meat to no more than 3 servings per weekLimit red meat to no more than 3 servings per week
Motivational Interviewing
Home visits and telephone counseling
Build rapport
Identify likes and dislikes re: diet and activity behaviors
Personalized needs assessment
Discuss how behaviors fit into lifestyle, how client would like things to be different
Goal setting
Feedback: re-evaluate behavior, increase self efficacy

RECRUITMENT AND RETENTION STRATEGIES
Maximizing participation Logistical issues – from Tamara
Dubowitz’s qualitative analysis of focus groups (n=44) for her doctoral defense, 2005.
Maximizing Enrollment
“Apple Awards” – recruitment incentives for WIC/health center staff
Expanded recruitment efforts to more WIC sites/health centers
Increased recruitment/data collector staff
Maximizing Retention
Offered phone visit option for intervention participants for which home visit scheduling was difficult
Offered phone counseling option only Combined Home Visits #4 and #5 Encouraged communication between
home visit (health mentor) and phone counseling staff for hard to reach participants
Increased monetary and gift incentives
Results of Qualitative StudyTamara Dubowitz 2005 “The Social Context of Diet: Using Mixed Methods to Understand Individual and Contextual Effects among Low-Income, Postpartum Women”
General themes The immigrant experience Social and geographic aspects of food
purchasing Food preparation within daily life activity
Recurring responses Limited time for family, cooking and food
purchasing Transportation and childcare obstacles
influenced food purchasing, preparation and consequently diet
The Immigrant Experience: Individualism versus family centered cultural norms
The difference for me is that in my country, you can talk to neighbors and everyone can do you a favor. Here – there is nothing, nobody is for nobody. Everyone is inside their own world. Years go by and you do not know who lives upstairs.
The Immigrant Experience: ‘time’ and ‘family’
During the weekends, in my country, we share more time with the family and friends mostly on Sunday, since there are people who work on Saturday. . . . . . . .Over here you do laundry, go to the supermarket and you are on a constant race if you did not finish something on a Saturday you have to do on Sunday.
The Immigrant Experience: Paying for childcare
The thing is that here you have to pay for childcare. Nobody watches the children for free.
If you want to work outside the house and have to pay for childcare it does not make any sense. So men have to work and we have to stay home with the children. Because to pay someone and have your kids with poor attention is not good. And all you earn working you have to pay for childcare.
Social and Geographical Aspects of Food Purchasing: Cost and Availability
I go to different places, because I don’t have much time to look for prices so wherever I am, I go shopping. Walmart now is selling food and Walmart is cheap , so there is a law in my house whoever goes to Walmart they need to grab some milk. We consume a lot of milk at home.
Social and Geographical Aspects of Food Purchasing: Proximity and Availability
. . . If we’re somewhere and they’re hungry. . .how can I not? You know, we can stop off at McDonalds and get a cheeseburger and french fries. It’s like a dollar. You know what I’m saying?
. . . I live right by it. And it’s cheap.
Everything is a dollar. You get your fries for a dollar, your cookies for a dollar
Food Preparation in Daily Life: length of the workday
I work three days a week. I don’t have time – for me. I get home late and I don’t want to think about cooking.
There’s days where you come home
from work and you’re like.. let me just throw that thing in the microwave. You find whatever you eat in the house.
Summary
Differing attitudes toward food purchasing and preparation Food preparation and purchasing more
central to daily life of immigrant women. The ‘immigrant experience’ played into food preparation and purchasing in the U.S.

Observations--Home Visits
Difficult to schedule, especially initial visit Caller ID sometimes a barrier, if women did not
recognize number (or did and chose not to respond)
Frequent cancellations, no-shows, causing time-management challenges
Many women reluctant to let a visitor into home Cleanliness Presence of others Environment (including safety)
Observations—Motivational Phone counseling
Women commit to calls more easily than home visits More anonymous
Time to build trust, rapport, no in-person contact (usually after two calls, women “opened up” )
Time frame more flexible for calling than scheduling visits Phone calls facilitate home visits in some cases Most valuable feature of calls is social support and
facilitate access to other community-based services
Challenges with intervention delivery
• Women did not associate or connect the various components and activities
• In spite of descriptive recruitment materials and verbal explanation
• Sequence of intervention activities following baseline survey
• Unique staff members for each activity (i.e. WIC staff who helped with referral, data collectors, health mentors)
Challenges common to this population
* Poverty * Depression
* Work, school responsibilities * Frequent pregnancy
* Unstable relationships * Language
* Acculturation difficulties * Isolation
* Transient living situation * Immigration issues
Lessons for the Future
• Collaborative teams of community partners and research facility
• Research can build on community infrastructure
• Research enhances community resources
* materials * staff
• One in-person intervention session with series of phone calls
• focus on one aspect of health behavior
• motivational interview style
• link with other community-based services
• other research with similar model shows positive outcomes
Future Considerations
