observe and record physical activity, including the address where the
physical activity was taking place, the number of participants, and
the activity in which they were engaged.
Results: Agreement was calculated for the address of the physical
activity, the number of participants involved and the type of activity
observed - 79.1%, 87.8% and 76.9%, respectively, with a combined
agreement of 81.3%. The number of participants for each activity
observed also is provided.
Conclusion: The levels of agreement were acceptable to conclude
that the BWM is reliable in a suburban setting, but there are a
number of procedural adjustments to be made to further enhance
the reliability.

DIFFERENCE BETWEEN SELF-REPORTED ENERGY INTAKE
AND ESTIMATED ENERGY REQUIREMENT IN A LATINO
POPULATION AT RISK OF DEVELOPING DIABETES

Objective: Underreporting of energy intake has been associated
with higher body mass index(BMI); however studies in minority
populations are limited. A cross-sectional analysis was conducted
to examine the difference between self-reported energy intake and
estimated energy requirement, and evaluate factors associated with
this difference, in a low income, lower literacy Caribbean Latino
community in Lawrence, Massachusetts.
Subject: One hundred and sixty-two Latinos were assessed as part of
a diabetes prevention study. The eligibility included a ≥30% risk of
developing diabetes in 7.5 years, assessed with the Stern formula.
Methods: Demographic, dietary, and psychosocial data collected at
baseline was used for this investigation. Dietary self-reported energy
intake was collected using three randomly selected days of 24-
hour diet recalls. Total energy expenditure was estimated using the
Mifflin-St Jeor equation.
Statistical Analysis: The energy difference was calculated using
24-hour derived energy intake minus estimated total energy
expenditure. Linear regression analysis was used to identify factors
associated with this difference.
Results: The population was predominately female (77%), average
age 51 years [standard deviation (SD)=11], BMI 35kg/m2
(SD=5.8), 62% had less than high school education, 56% were
unemployed, and 35% had siblings with diabetes. Reported total
daily energy intake was 1552 kcal (SD=610), whereas daily total
energy expenditure was estimated at 1909 kcal (SD=315), with a
difference of -357 kcal (SD=591). Higher BMI, having siblings
with diabetes, and being married was positively associated with
underreporting of energy intake.
Applications/Conclusions: This is the first study to describe dietary
intake under-reporting in a low-income, lower literacy Caribbean
Latino population. It has implications for future analyses and
collecting of the dietary data in this population.

A COMPARISON OF BODY IMAGE DISCREPANCY
MEASUREMENT IN THE LABORATORY AND DAILY LIFE
Kristin Heron, MS and Joshua Smyth, PhD
Syracuse University, Syracuse, NY.
Self-discrepancy theory is a useful framework for exploring how
individuals view their bodies. Body image discrepancies [BID]
result from conflicting beliefs about one’s actual body and the body
one would ideally like to have (actual:ideal discrepancy [A:I]), or
beliefs about the body one ought to have (actual:ought [A:O]). BID
are interpreted as a measurement of body image dissatisfaction,
and are associated with disordered eating behaviors, dieting, and
weight control attempts. BID are generally measured using a figure
rating scale in a laboratory or clinical setting, although there is
little evidence that this measurement technique represents actual
experiences. Laboratory-based assessments may be problematic as
phenomenon measured in artificial settings may not be indicative
of processes that occur in the real world. This study used Ecological
Momentary Assessment [EMA] to assess BID in everyday settings.
College women (n=63; mean age=19.0) completed BID measures
in a laboratory and five times daily for one week on palmtop
computers. EMA data were analyzed in SAS PROC MIXED,
accounting for the nested data structure. Significant A:I and A:
O discrepancies existed on both laboratory and EMA measures
(p’s.19). These data indicate that women’s
BID can be measured in everyday life. Furthermore, discrepancies
assessed in laboratory and via momentary measures in the natural
environment show convergent validity. This is the first study to
measure body image in real time and suggests that that researchers
and clinicians can be confident that laboratory BID measures are
ecologically valid and comparable to real world assessments. Future
research may benefit from using EMA to examine contextual
influences on BID.
