Effectiveness of Video Messaging About Diet, Exercise and Weight Gain in Pregnancy in Regional and National Samples

The primary purpose of this study is to assess the responses of pregnant women and their social network to six videos about health in pregnancy. Our goal is to assess a) acceptability and b) understanding of core messages about healthy eating, exercise and weight gain during pregnancy. We will also assess c) non-clinical sources of health information during pregnancy.

Study Overview

• Status: Completed
• Conditions: Pregnancy; Weight Gain
• Intervention / Treatment: Behavioral: Responses to Brief Video Messages (Facebook); Behavioral: Response to Brief Video Messages (Clinic); Behavioral: Response to Brief Video Messages (Social Network)

Detailed Description

Many women engage in suboptimal lifestyle behaviors during pregnancy. Many women do not realize that unhealthy diet, exercise and weight gain behaviors can be dangerous for their pregnancy and have harmful long-term consequences for their baby. There is great need for strategies to promote accurate knowledge about healthy behaviors during pregnancy. The purpose of this study is to assess responses to a brief (<1minute) video about healthy behaviors during pregnancy. The study sample will include pregnant women and members of their social network. Participants will be asked to watch a brief video and complete an anonymous online survey measuring their response to the video, and their basic demographics. The surveys will also assess how family and friends impact pregnant women's health behaviors. Online surveys are entirely anonymous. We will recruit pregnant participants from two sources: the University of Michigan Health System's prenatal clinics and a social media website (Facebook).

Study Population

Women recruited via either the social media, clinical, or online approach will be eligible for participation if they are aged 18 years and older, pregnant, and English-speaking. Women will be excluded if they deny being currently pregnant, do not identify as living in the US and aged 18 years or older, or if they report having previously participated in the study. The Qualtrics survey will automatically conclude if potential participants provide answers to screening questions that deem them ineligible. Participants will not be excluded based on racial-ethnic groups. Males will be excluded, as this is a study involving pregnant women.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Facebook Survey Group; During June, 2015, approximately 1200 women will be recruited through Facebook advertisements targeted at English-speaking women age 18-50 years living in the United States. Advertisements will contain 3 key features: an image, a caption, and "ad copy" followed by a link to the survey website. Individuals who click on the study link in the advertisement will be redirected to the study's Qualtrics web page where they will take a 15 web-page, multiple choice survey developed by the research team. The survey covers these domains: reaction to video, understanding of core message, self-efficacy around lifestyle behaviors, attitudes, beliefs and intentions regarding vaccination during pregnancy, key health information sources during pregnancy, and demographics.	Behavioral: Responses to Brief Video Messages (Facebook); Participants view 1 of 6 brief video messages about health in pregnancy, then answer survey questions that will assess their a) acceptability, b) understanding of core messages, and c) self-efficacy about healthy eating, exercise and weight gain during pregnancy.
Clinical Survey Group; During June-August, 2015, approximately 500 women will be recruited at routine obstetric visits to the University of Michigan's outpatient clinics. Women who check in for an Ob appointment will be offered the opportunity to participate in an anonymous online survey. Individuals who express interest in participating will be provided with a laptop and headphones and directed to the survey Qualtrics site where they will take a 15 web-page, multiple choice survey developed by the research team. The survey covers these domains: reaction to video, understanding of core message, self-efficacy around lifestyle behaviors, attitudes, beliefs and intentions regarding vaccination during pregnancy, key health information sources during pregnancy, and demographics.	Behavioral: Response to Brief Video Messages (Clinic); Participants view 1 of 6 brief video messages about health in pregnancy, then answer survey questions that will assess their a) acceptability, b) understanding of core messages, and c) who in her social network she turns to for non-clinical health advice and what kinds of advice she gotten in the past.
Social Network Group; Once a pregnant participant completes the survey, she will be asked to provide her email address. If she is willing to do so, Qualtrics will automatically send her an email containing a weblink to the survey for her social network. She can then provide this link to 1 or 2 social network members that she feels influence her health behaviors during pregnancy. These members are asked similar questions about their response to the video, as well as some additional questions about how they advise their pregnant person about different health topics. It is necessary to provide a unique weblink to her, so that the survey responses from the pregnant woman and her unique social network members can be linked.	Behavioral: Response to Brief Video Messages (Social Network); Participants view 1 of 6 brief video messages about health in pregnancy, then answer survey questions that will assess their a) acceptability, b) understanding of core messages, and c) how they advise their pregnant friend about different health topics.
