Abstract 13983: Short-term Changes in Lifestyle Risk Factors and Incident Metabolic Syndrome in the Heart of New Ulm Project
Objective: To examine the association between changes in Optimal Lifestyle Score (OLS) and incident metabolic syndrome(MS) over 2 years, and to examine which components of the OLS are most strongly associated with incident MS.
Method: The study sample comes from the Heart of New Ulm Project, a community-based CVD prevention program. Participants in heart health screenings from both 2009 and 2011, without MS at baseline, made up the study sample. The primary independent measure was change in the OLS, which is a composite summary of smoking, fruit/vegetable consumption, alcohol use, physical activity, and BMI. For each participant, changes in the OLS score and its subcomponents were categorized as improved, declined, or stable. Logistic regression models predicting incident MS were run with the OLS change category as the primary independent measure and a separate model was run examining the contribution of change in each individual OLS component toward metabolic syndrome. Models were adjusted for baseline values, education, age, gender, diabetes, and heart disease status.
Results: In 2009, 1,059 of screened residents did not have MS, with 123 (12%) going on to develop MS by 2011. A decline in the OLS was associated with a nearly 3-fold increased risk of incident MS (aOR = 2.9, CI: 1.69, 5.04). Changes in BMI and fruit/vegetable consumption were the OLS components most strongly associated with MS. Adjusted ORs for incident MS in the final model were 8.6 for those who became obese, and 3.9 for those whose fruit and vegetable consumption declined below 5 servings per day over the 2 years.
Conclusions: These findings support the use of an easily calculated OLS in community-based CVD prevention programs, and underscore the importance of nutrition in the near-term development of MS. Findings support national recommendations encouraging individuals to achieve energy balance and increase fruit and vegetable consumption to improve health and prevent disease.
