Results from an Evaluation of the Georgia Colorectal Cancer Control Program's Community Education and Outreach Events, 2013.

Although public health practitioners commonly use community education and outreach events to promote cancer screening, the effectiveness of this strategy remains unclear. This study evaluated 23 outreach events, conducted as part of the Georgia Colorectal Cancer Control Program. Of the estimated 1778 individuals who attended these events, those ages 50-75 were eligible to participate in a telephone survey 3 months after attending an event. Surveys measured colorectal cancer (CRC) risk status, CRC screening history at the time of the event, seeking or obtaining CRC screening at 3-month follow-up, and participants' knowledge of their CRC screening status. Of the 335 individuals contacted for this evaluation, 185 completed the survey. Eighty participants (43.2 %) were at elevated risk for CRC and 99 participants (53.5 %) were at average risk. Of the 99 average-risk participants, the majority (n = 69) were not due for CRC screening at the time they attended an event because they had previously received screening within the recommended time intervals. Thirty average-risk participants were due for CRC screening, either because they had never been screened before (n = 19) or because they were due for rescreening (n = 11). Approximately half of these 30 participants who were due for screening either sought (n = 6, 20.0 %) or obtained screening (n = 8, 26.7 %) 3 months following the event. Community education and outreach events may play an important role in motivating participants to seek or obtain CRC screening, but unless priority audiences are identified and recruited, events may attract people who are already compliant with CRC screening.

Carotenoid bioavailability is higher from salads ingested with full-fat than with fat-reduced salad dressings as measured with electrochemical detection.

BACKGROUND: The amount of dietary fat required for optimal bioavailability of carotenoids in plant matrices is not clearly defined. OBJECTIVE: The objective was to quantify the appearance of carotenoids in plasma chylomicrons after subjects ingested fresh vegetable salads with fat-free, reduced-fat, or full-fat salad dressings. DESIGN: The subjects (n = 7) each consumed 3 salads consisting of equivalent amounts of spinach, romaine lettuce, cherry tomatoes, and carrots with salad dressings containing 0, 6, or 28 g canola oil. The salads were consumed in random order separated by washout periods of > or =2 wk. Blood samples were collected hourly from 0 to 12 h. Chylomicrons were isolated by ultracentrifugation, and carotenoid absorption was analyzed by HPLC with coulometric array detection. RESULTS: After ingestion of the salads with fat-free salad dressing, the appearance of alpha-carotene, beta-carotene, and lycopene in chylomicrons was negligible. After ingestion of the salads with reduced-fat salad dressing, the appearance of the carotenoids in plasma chylomicrons increased relative to that after ingestion of the salads with fat-free salad dressing (P < 0.04). Similarly, the appearance of the carotenoids in plasma chylomicrons was higher after the ingestion of salads with full-fat than with reduced-fat salad dressing (P < 0.02). CONCLUSIONS: High-sensitivity HPLC with coulometric array detection enabled us to quantify the intestinal absorption of carotenoids ingested from a single vegetable salad. Essentially no absorption of carotenoids was observed when salads with fat-free salad dressing were consumed. A substantially greater absorption of carotenoids was observed when salads were consumed with full-fat than with reduced-fat salad dressing.
