The Value of Using a Syndemics Theory Conceptual Model to Understand the Factors Associated with Obesity in a Southern, Urban Community Sample of Disadvantaged African-American Adults.

For this study, a syndemics theory approach was used to examine the factors associated with adulthood obesity in a community-based sample of African-American adults. Interviews were conducted with 1,274 African-American adults residing in Atlanta, Georgia in 80 strategically chosen census tracts, selected on the basis of factors such as low household income, low levels of educational attainment among heads of household, and low levels of labor force participation. Comparisons were made between normal-weight persons (body mass index [BMI] = 18.5-24.9; n = 800) and obese persons (BMI = 30.0 or greater; n = 474). Structural equation analysis was used to examine the interrelationships among variables. One quarter (25.6%) of the study participants were classified as obese. Five factors were related directly to obesity. These were gender, age, relationship status,frequency of eating 3 meals per day, and frequency of alcohol consumption. The frequency of alcohol consumption was an endogenous measure and 7 factors were identified as underlying this measure. The 7 factors were gender, age, sexual orientation, self-esteem, impulsivity, criminality of friends, and neighborhood violence. The structural model developed for this study proved to be useful for conceptualizing the factors underlying obesity and there was considerable evidence of syndemic effects among key predictors. The myriad factors underlying obesity in this population interacted with one another in such a manner as to support the use of syndemics theory-based models in future research. In particular, obesity researchers might wish to consider the interplay of demographic factors such as age and gender, psychosocial characteristics such as self-esteem and impulsivity, alcohol use/abuse, and community factors such as neighborhood violence and criminality influences.
