Preventing Chronic Disease

Introduction: In California's agricultural Central Valley, the rate of childhood obesity is higher than the national average. Adequate physical activity contributes to obesity prevention and its assessment is useful to evaluate the impact of interventions. Methods: Niños Sanos, Familia Sana (Healthy Children, Healthy Family [NSFS]) uses community-based participatory research to implement an intervention program to reduce childhood obesity among people of Mexican origin in the Central Valley. Anthropometric measurements were conducted on more than 650 children enrolled in NSFS. Physical activity data from a subgroup of children aged 4 to 7 years (n = 134) were collected via a wearable accelerometer. Results: Children were classified on the basis of age and sex-adjusted body mass index as healthy weight (57.7%); overweight (19.3%), or obese (23%). Logistic regression showed that moderate to vigorous physical activity (MVPA) was associated with a child's likelihood of having a healthy BMI (odds ratio: 1.03; 95% CI, 1.01-1.05; P = .017). Conclusion: NSFS's community-based participatory approach resulted in successful use of a commercial electronic device to measure physical activity quantity and quality in this hard-to-reach population. Promotion of adequate daily MVPA is an appropriate and necessary component of NSFS's childhood obesity prevention strategy. Source

This article focuses on the role of omega-3 fatty acids as precursors for lipid signaling molecules known as oxylipins. Although omega-3 fatty acids are beneficial in autoimmune disorders, inflammatory diseases and heart disease, they are generally underrepre-sented in the American diet. A literature review confirms that the consumption of omega-3 fatty acids - whether in food sources such as walnuts, flax seeds and fatty fish (including salmon and sardines), or in supplements - is associated with decreased morbidity and mortality. This growing body of evidence, including the results of a recent study of patients with kidney disease, highlights the need to measure omega-3 fatty acids and their oxylipin products as markers of metabolic health and biomarkers of disease. In addition, there is substantial evidence of the need to increase the omega-3 fatty acid content of American diets to optimize metabolic health. Source

A number of researchers share their views regarding factors that have a significant impact on a more personalized approach to diet and health. They believe that diet and health will gradually become a personal knowledge management system in the same way as in many other existing complex human activities. Consumers need to be informed about their health status and to be confident that the steps that they are taking to improve it are working. The food industry needs to know that there are consumers with unmet needs for their particular products and that they can demonstrate in those consumers that their products are achieving the health goals that their products claim. Diet can also begin to act in a more pre-emptive manner in improving the health with a more personalized approach to health through measurement and guidance. Source
