Non Technical Summary
There is a strong link between diets high in fruits and vegetables and decreased risk for certain chronic diseases. Low-income individuals have a disproportionately higher risk for these diseases, yet consume lower levels of fruits and vegetables. The goal of this study is to understand factors predicting fruit and vegetable intake by low-income African American mothers of young children through the application of the Transtheoretical model. This model involves a series of stages of readiness to change eating behaviors, perceptions of benefits (pros) and barriers (cons) to change, and processes used to change behavior. In the first year, information will be gathered by observation and interview as to how decisions are made about incorporating fruits and vegetables into diets for children. Verbalizations as part of a The purpose of the project is to understand factors predicting fruit and vegetable intake by low-income African American mothers of young children.

Goals / Objectives
1) To understand food choices and decision making in context related to fruit and vegetable intake for mothers and how they provide these foods to their children; 2) To identify the pros and cons of increasing fruit and vegetable consumption in mothers with young children; 3) To identify the specific processes of change used to increase fruit and vegetable consumption in mothers with young children; 4) To determine whether participation in specific processes of change, strength of perceptions of pros and cons, and stage are associated with the provision of fruits and vegetables to children in the household; and 5) To determine whether socio-demographic variables such as age, racial background, household size, marital status or education predict intake, stage, participation in specific processes of change, or the strength of perceptions of pros and cons of change.
Project Methods
In the first year, information related to how the target audience makes decisions about incorporating fruits and vegetables into the diets for themselves and their children will be gathered in the context where these decisions are made. Information will be gathered by observation and interview from women in each of the 5 stages of readiness to change intake of fruits or vegetables. This includes decisions related to planning for, procuring, handling and preparing, serving, and eating fruits and vegetables. Information related to factors affecting these decisions as they relate to pros and cons of change and processes of change will also be collected by observational and interview methods. These data will be used to develop a survey tool, which will be administered during the second year. The survey will determine how the pros and cons of change and processes of change identified in the first phase of the study are related to intake and stage of readiness to change in a larger sample from the target audience. The carefully planned step involving qualitative data collection in the first phase of the study should enhance the likelihood of collecting valid and useful survey data in the second phase of the study.

Outputs
In the first phase, information related to how low income African American mothers make decisions about incorporating fruits and vegetables into the diets for themselves and their children was collected in the context where these decisions are made. Information was gathered by observation and interview from 10-18 women in each of the 5 stages of readiness to change intake of fruits or vegetables in the grocery store as they shopped for a significant quantity of groceries, and in their home as they prepared a family meal. Verbalizations as part of a "think loud" protocol were recorded in the grocery store and at home from a total of 70 women. Data were analyzed using qualitative data analysis procedures. In the second phase, think aloud data collected in the first phase were used to generate survey items related to pros and cons to change, self-efficacy, processes of change used, and frequency of practices related to providing fruits and vegetables to children. The survey was pretested to establish acceptable internal consistency. Women were recruited according to stage of change prior to completing the survey. Survey data collection was completed after a 9-month period of time with data collected from 41 women in the precontemplation stage and 80-120 women per stage for the remaining 4 stages (total number of respondents = 434). Analysis of variance showed that there were no socio-demographic differences by stage of change. Those in the later stages consumed about 10 servings of fruits and vegetables per day compared to about 3 per day for those in earlier stages. Pro scores, self-efficacy scores, and the use of 7 of 10 of both the experiential and behavioral processes of change increased as stage advanced. Principal components analysis identified 5 factors from the decisional balance scale, 3 of which were related to stage of change including health benefits and characteristics that facilitate preparation and planning. The reported frequency of most practices used by mothers to provide fruits and vegetables to children was positively associated with authoritative parenting index responses, stage of change, and self-efficacy with the strongest correlations observed with self-efficacy. These practices involved preparation and feeding strategies, modeling, and making foods available and accessible. Stage of change, pro scores, and self-efficacy scores were also associated with authoritative parenting index responses. The current study offers a different perspective compared to other studies involving fruit and vegetable consumption and stage of change in African American adults because all constructs of the Transtheoretical Model were applied, a staging mechanism that was thought to be more accurate was used, and subjects were classified prior to recruitment into the study. The findings of this study confirmed the expected pattern of relationships between the constructs of the Transtheoretical Model and stage of change for fruit and vegetable consumption for low-income African American mothers and the potential application for future intervention programs.

Impacts
The results of this study will be used to develop educational materials for use in counseling of African American mothers of young children to modify their eating patterns and practices related to provision of fruits and vegetables to their children. In regard to self-efficacy, future intervention efforts for those in earlier stages should incorporate education and development of skills to increase consumption outside of the home environment and when busy and emphasize the health benefits of changing behavior, as well as improving preparation and planning strategies. Helping women in the earlier stages overcome barriers and improve self-efficacy for increasing their own fruit and vegetable intake may also increase the frequency with which they engage in practices to provide fruits and vegetables to their children. For example, mothers with higher intakes in the later stages have fruits and vegetables available to them, which is likely to improve their availability for children in the home. Parent education should also focus on practices reflective of an authoritative or positive parenting style regarding fruit and vegetable intake.

Progress 01/01/02 to 12/31/02

Outputs
Greater fruit and vegetable intake is protective against cancer and heart disease, however, intake is below recommended levels for young African American mothers who have disproportionately higher risk for chronic disease. The objective of this study was to use the Transtheoretical Model to identify determinants of fruit and vegetable consumption in this population. Participants were classified according to one of five stages for eating 5 daily servings of fruits and vegetables. Stages progress from not thinking about changing to having made and maintained changes for 6 months. Women were asked to verbalize all thoughts while shopping for groceries and preparing a meal at home to collect information concerning food selection and preparation practices. Verbalizations were audiotaped and tapes were transcribed verbatim. Encoded units of the text were sorted using a database software program and data were analyzed using a content analysis procedure. Seventy women participated in the study. The average age was 32 years; 42% participated in WIC, 66% were single mothers, and 51% had some college education. The total daily fruit and vegetable servings according to stages were: 2.7 (precontemplation), 2.9 (contemplation), 4.2 (preparation), 9.9 (action), and 9.4 (maintenance). The major factors affecting decision-making related to fruit and vegetable purchasing and preparation were cost, preferences, and specific needs regarding family members or eating occasions. Concerns about nutrition and health were more important considerations in fruit and vegetable purchasing and preparation decisions made by women in later stages. In later stages women verbalized more about aspects related to preferences for quantity and variety of fruits and vegetables in meal planning. These stage-based differences in factors considered in decision-making related to fruit and vegetable purchasing and preparation may contribute to differences in intake between women in different stages. Eating patterns develop early in childhood and can contribute to health issues later in life. These data were also analyzed to identify child-feeding strategies related to the mother's stage of change for fruit and vegetable consumption. Child-feeding strategies included accommodating child preferences, subtle coercion, teaching, and positive and negative role modeling. Though there seemed to be some concern in all stages that children eat healthier, results showed that mothers in the later stages of change were increasingly more involved and implemented more complex strategies to increase fruit and vegetable consumption by their children. The information from this study has been used to develop a survey to further substantiate the determinants of fruit and vegetable intake identified. Survey data collection is currently underway.

Impacts
The results of this study will be used to develop educational materials for use in counseling of African American mothers of young children to modify their eating patterns and practices related to provision of fruits and vegetables to their children. Tailoring counseling sessions according to practices specific to the various stages of change may allow practitioners to be more successful in helping clients change eating behaviors. Changes in fruit and vegetable consumption are more likely to occur when educational interventions are targeted toward one's stage of readiness to change. Greater consumption of fruits and vegetables is associated with reduced risk for chronic diseases.

This information will be used to develop a survey tool, which will be administered during the second year. The survey will determine how the pros and cons of change and processes of change are related to intake and stage of readiness to change in a larger sample from the target audience.

Impacts
It is anticipated that achieving the objectives for the study will further the understanding of factors predicting intake of fruits and vegetables by low income African American mothers through integration into an appropriate theoretical framework. The development of effective interventions can be based on knowledge of predictive factors, thereby contributing to the likelihood of dietary behavior change for this audience thereby reducing disparities in health risk behaviors and preventing chronic disease.
