WEIGHT CONTROL TO PREVENT CANCER IN AFRICAN AMERICANS
AbstractDESCRIPTION: The proposed research involves the development and field
testing of a model weight control program for Cancer Prevention with low
income African American women aged 20 to 64 in the Boston area. During year
one, extensive formative evaluation will be conducted with members of the
potential audience through a combination of qualitative techniques from
cultural anthropology and social marketing. The formative procedure will
enable the investigators to develop a culturally appropriate intervention
program for low income African American women by determining the logistical
and cultural barriers and facilitators to successful diet and physical
activity changes they encounter in attempts to reach and maintain their
desirable weight. Cable television will be the primary program delivery
channel. The program will utilize the "pay per view" feature of cable
television to insure integrity of the experimental design and greatly
enhance the generalizability and potential replicability of the approach.
Principal design features include random assignment of participants to
experimental condition, and testing of two major components: interactive
verses passive television programming and enhanced vs non-enhanced social
support in a two by two factional design. In the IATV condition,
participants will interactively participate by telephone in the live cable
television delivery of 12 weekly sessions followed by four monthly booster
programs. The passive television groups will view the programs without
being actively involved. Half of the interactive and passive groups will
receive an enhanced "out of classroom" component with increased social
support including telephone problem solving based on motivational in viewing
and delivered by trained African American lay health advocates recruited
from low income Boston neighborhoods. The other half of the interactive and
passing groups will not receive this enhanced social support component. The
rest of the participants will be assigned to a "waiting list" control
groups. Process evaluation will include tracking of programs viewed by
participants, number and topics of calls into programs, audio recording of
the lay health advocates telephone sessions, and comparative costs of the
four interventions. Outcome evaluation will include changes in diet and
physical activity and weight and body circumference measurements at baseline
and 3, 7.5 and 12 months later. The final product will be a model program
readily adaptable by health care and public health organizations for their
local populations.
