Hi all,
Our next virtual meeting will be Wednesday April 15, where we
will hear Briana Stephenson present research on “*Empirically Derived
Dietary Patterns using Robust Profile Clustering*”.
*Abstract*: Mixture models have been of great utility in exploring dietary
behaviors over a wide set of foods and beverages in a given population, but
are prone to overgeneralize these habits in the presence of variation by
subpopulations. This research aimed to highlight unique dietary consumption
differences by both study site and ethnicity in Hispanic/Latino populations
in the United States, that otherwise might be missed in a standard mixture
model of the overall population. We achieve this using a new model-based
clustering method, referred to as Robust Profile Clustering (RPC). A total
of 11,331 Hispanic/Latino individuals aged 18-74 years from the Hispanic
Community Health Study/Study of Latinos (2008-2011) with complete diet data
were classified into 9 subpopulations, defined by study site (Bronx,
Chicago, Miami, San Diego) and ethnic background. Patterns were derived
from dietary intake ascertained on the Food Propensity Questionnaire to
identify consumption behaviors of the general Hispanic/Latino population
and those specific to an identified subpopulation. In this talk, we will
discuss these results, their implications for addressing minority
population health, and future directions to improve nutrition epidemiology
and disparities in a continually diversifying population.
The methods applied in this study are described in detail in the attached
paper
