- Sodium intake has historically been studied as a precursor to cardiovascular disease morbidity and mortality, particularly in relation to blood pressure and development of hypertension. Recent observational studies highlight a possible relationship between sodium and obesity independent of higher caloric intake. This research letter explores the relationship between sodium intake measured in 24-hour urine samples and measures of body size such as obesity, BMI, weight, and waist circumference using proxy adjustments for unavailable energy intake data.
- To the Editor: In a recent issue, Katula and colleagues1 report an RCT that demonstrated the effectiveness of a community-based lifestyle intervention on weight, waist circumference, insulin resistance, and blood glucose up to 2 years. In addition to achieving long-term effects that were on par with the Diabetes Prevention Program lifestyle intervention,2 the intervention was elegantly designed to be implemented in a manner to facilitate sustainability in a real-world community setting. The intervention was conducted in community parks and recreation centers where kitchens and communal space were utilized for cooking demonstrations, exercise classes, and group meetings.
- Several studies convincingly suggest that obesity rates and all-cause related mortality are increasing.1 Dietary and lifestyle interventions such as weight loss and physical activity are effective to prevent obesity.2,3 In an elegant manuscript, Kraak et al.4 have evaluated the efforts made by the food industry to encourage a healthier food supply to American children and adolescents and thus prevent obesity. One of the criteria pointed out and evaluated by the authors was the development of the front-of-package (FOP) labeling for consumers to identify healthy products.
