Madres Para la Salud (Mothers for Health)

24. Juli 2013 aktualisiert von: Colleen Keller, Arizona State University

The purpose of "Madres Para la Salud" [Mothers for Their Health] is to see how support and encouragement can help women to make positive changes in their health. This program tested if supportive information, encouragement, and walking as a group would increase physical activity and health benefits, such as weight loss and postpartum depression.

Participants in this study were randomly assigned to one of two groups, a walking or a non-walking group. The walking group met weekly. Participants were given a pedometer to record the number of steps taken daily.

Participants met one time each week with our study staff. Participants walked four other days per week on their own, or with other group members. Participants measurements included body fat, waist, and hip at the beginning of the study, and at 3, 6, 9, and 12 months. The non-walking group received a weekly mailed newsletter about topics such as parenting, infant growth and development, and reproductive health. Non-walking group participants' measurements included body fat, waist, and hip at the beginning of the study and at 6 and 12 months.

Project Summary

The purpose of "Madres para la Salud" (Mothers for Health) was to explore the effectiveness of a culturally specific intervention using walking "bouts" to affect changes in the health of Hispanic women following childbirth. The project will advance our understanding of the relationship between moderate increases in physical activity and consequent body fat loss and decreased postpartum depression symptoms in sedentary Hispanic women during the postpartum period. This was accomplished by having a group of women who participated in supportive information and walking sessions, both alone and with study personnel, and an attention control group who received monthly phone calls to address common postpartum health concerns, but who did not participate in the walking program. Both groups received weekly health-focused newsletters with no content related to the intervention. The women had a random assignment to a group.

Study Aims

The purpose of this social support intervention program was to test the theory-driven Madres para la Salud with Hispanic women by conducting a formative evaluation of the intervention:

Aim 1: Examine the effectiveness of the Madres para la Salud, a theoretically driven social support intervention for reducing the distal outcomes in: (a) body fat; (b) systemic and fat tissue inflammation; and (c) PPD symptoms among postpartum Hispanic women compared with an attention control group, at 6 and 12 months, after controlling for dietary intake.

Aim2: Test whether the theoretical mediators, intermediate outcomes, of social support and walking, and environmental factor moderators, affect changes in body fat; systemic and fat tissue inflammation; and PPD symptoms among postpartum Hispanic women completing the Madres para la Salud intervention compared with an attention control group, at 6 and 12 months, after controlling for dietary intake.

Aim 3: Determine the relationship between the immediate outcome of walking (minutes walked per week) and change in the distal outcomes of: (a) body fat; (b) systemic and fat tissue inflammation; and (c) PPD symptoms.

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: Madres para la Salud
Participants attended Madres para la Salud sessions in a group, led by a promotora at the Maricopa Medical Center and other community based sites. Sessions consisted of a 30 minute education and social support session where women learned to walk at least 150 minutes a week at a 20 minute-mile pace, and up to 30 minutes of moderate intensity walking with the group. Participants received an Omron pedometer and learned to monitor walking intensity. Participants set and reviewed weekly walking goals at the group sessions and recorded aerobic steps per day. After the 12 week sessions, participants met with the promotora once a week for 40 weeks, in-group, to walk at a moderate intensity for 30 minutes, to download and review pedometer data. Data was collected at baseline, 3, 6, 9 and 12 months.

Kein Eingriff: Attention-control
Participants in the attention receive monthly brief telephone calls by research technicians and collection of study data on-site at the Maricopa Medical Center and other community based sites at baseline, 6, and 12 months (T1, T3, T5). The staff did not give advice or support specific to walking, which enabled a valid evaluation of the intervention effect. The content given to the attention-control group did not include the "active ingredients" of the Madres para la Salud intervention. The attention-control group received monthly mailings of health-related information regarding common postpartum or newborn concerns, such as breastfeeding, infant sleep, sibling rivalry, emotional support related to new parenthood, and early childhood development topics.

Change from Baseline Body Fat Percentage at 6 months
Zeitfenster: 6 months
Body fat was measured using bioelectric impedance (BIA), with portable four-terminal BIA measurement system (Tanita Corporation of America, Inc, Arlington Heights, IL). Instrument calibration was performed internally prior to each estimate of body composition. Measurement of body composition using BIA analysis followed the method outlined by Ritchie, Miller, and Smiciklas-Wright (Ritchie, Miller, & Smiciklas-Wright, 2005). A subsample of the intervention group had body fat measured with state-of-the-art dual energy x-ray absorptiometry (DEXA) at baseline and 12 months.
