DESCRIPTION: (adapted from Investigator's abstract) We propose to test the
efficacy of an intervention designed to prevent obesity and increase fruit and
vegetable consumption in low-income, Mexican American children by improving
mothers' food-related parenting practices.
Mexican-American children are more obese than other minority groups in the U.S.
population. Moreover, Hispanics are the fastest growing minority in the U.S.A.
Poor dietary practices, especially food habits that are acquired as families
acculturate to the American food supply, are thought to be associated with
children's weight. Therefore, a video/problem solving intervention designed to
provide mothers with the skills needed to promote healthy foods to her family
was developed. After watching the video, mothers are engaged in a conversation
with a community health advisor about the most problematic eating behaviors for
her family portrayed in the video. Together, they plan strategies that mothers
may implement to change her family's food habits in the upcoming weeks. This
intervention has been received positively by Mexican-American mothers involved
in pilot research.
A study in which 50 families receive the video/problem solving intervention and
50 families receive an active placebo control is proposed. Mothers and their
fifth grade children will be randomly selected from 8 low-wealth elementary
schools. Intensive measures will be used to assess the effectiveness of the
intervention. Children will provide height and weight measurements, 24-hour
recalls, and photographic food diaries. Data collected from mothers will
include height and weight, household food inventories, household food security,
food purchase motives, family food interaction and acculturation.
We hypothesize that within a 6 month timeframe, children's whose mothers are
exposed to the video/problem solving intervention will reduce their prevalence
of obesity compared to children whose mothers receive the control intervention.
The primary outcome variable will be body mass index. The secondary outcome
will be children's fruit and vegetable consumption and energy intake.
