OBJECTIVES/GOALS: Greater blood pressure (BP) reactivity and socioeconomic deprivation (e.g., area deprivation index; ADI) are associated with poor vascular health [1-3]. However, it is unclear if ADI is associated with BP reactivity. Thus, we sought to examine if ADI is associated with BP reactivity in young adults. METHODS/STUDY POPULATION: Participants completed questionnaires used to derive lifetime ADI averaged from early-, mid-childhood, and adolescence. Participants completed a handgrip (HG) exercise protocol including 10 minutes of rest, 2 minutes of static HG at 40% of their maximal voluntary contraction, 3 minutes of post-exercise ischemia (PEI), and 2 minutes of recovery (REC). Beat-to-beat BP (photoplethysmography) and heartrate (HR; electrocardiogram) were continually assessed. We used the Shapiro-Wilk test to assess data for normality. We examined associations between ADI, BP reactivity, and HR using unadjusted and body mass index (BMI), sex, and race-adjusted Pearson’s correlation (set a priori to 0.05). RESULTS/ANTICIPATED RESULTS: This study included 53 (27Males/26Females; 21 ± 1 years; 24Black/29White; BP 107 ± 9/64 ± 9 mmHg) participants. There were racial differences (Black compared to White adults) for several BP reactivity metrics (e.g., PEI minute 3 diastolic BP: 96 ± 15 vs. 84 ± 19 mmHg, p=0.014) and lifetime ADI (p0.050). DISCUSSION/SIGNIFICANCE: Our data suggest racial differences exist in socioeconomic deprivation in a modestly sized young adult sample living in the southeast. While additional data are needed for other stressors, socioeconomic deprivation was not independently associated with BP or HR reactivity during acute exercise.

Few studies have derived data-driven dietary patterns in youth in the USA. This study examined data-driven dietary patterns and their associations with BMI measures in predominantly low-income, racial/ethnic minority US youth. Data were from baseline assessments of the four Childhood Obesity Prevention and Treatment Research (COPTR) Consortium trials: NET-Works (534 2–4-year-olds), GROW (610 3–5-year-olds), GOALS (241 7–11-year-olds) and IMPACT (360 10–13-year-olds). Weight and height were measured. Children/adult proxies completed three 24-h dietary recalls. Dietary patterns were derived for each site from twenty-four food/beverage groups using k-means cluster analysis. Multivariable linear regression models examined associations of dietary patterns with BMI and percentage of the 95th BMI percentile. Healthy (produce and whole grains) and Unhealthy (fried food, savoury snacks and desserts) patterns were found in NET-Works and GROW. GROW additionally had a dairy- and sugar-sweetened beverage-based pattern. GOALS had a similar Healthy pattern and a pattern resembling a traditional Mexican diet. Associations between dietary patterns and BMI were only observed in IMPACT. In IMPACT, youth in the Sandwich (cold cuts, refined grains, cheese and miscellaneous) compared with Mixed (whole grains and desserts) cluster had significantly higher BMI (β = 0·99 (95 % CI 0·01, 1·97)) and percentage of the 95th BMI percentile (β = 4·17 (95 % CI 0·11, 8·24)). Healthy and Unhealthy patterns were the most common dietary patterns in COPTR youth, but diets may differ according to age, race/ethnicity or geographic location. Public health messages focused on healthy dietary substitutions may help youth mimic a dietary pattern associated with lower BMI.

A controversy at the 2016 IUCN World Conservation Congress on the topic of closing domestic ivory markets (the 007, or so-called James Bond, motion) has given rise to a debate on IUCN's value proposition. A cross-section of authors who are engaged in IUCN but not employed by the organization, and with diverse perspectives and opinions, here argue for the importance of safeguarding and strengthening the unique technical and convening roles of IUCN, providing examples of what has and has not worked. Recommendations for protecting and enhancing IUCN's contribution to global conservation debates and policy formulation are given.
