  21. Increase physical activity • Key strategies • PE in schools • Physical activity regulations in child care • Safe Routes to School • Incentives • Access to places for pa with informational outreach • Social supports for change • Comprehensive community campaigns

  22. Healthy People 2010Physical Activity Objective 22-2 • Increase the proportion of adults who engage in: • Moderate physical activity for at least 30 minutes per day 5 or more days per week; or • Vigorous physical activity for at least 20 minutes per day 3 or more days per week http://www.healthypeople.gov/

  23. 2008 Physical Activity Guidelines for Americans – Adult Guidelines Aerobic Physical Activity Guidelines ≥ 150 minutes of moderate-intensity aerobic activity per week; or ≥ 75 minutes of vigorous-intensity aerobic activity per week; or Equivalent combination of moderate- and vigorous-intensity physical activity http://www.health.gov/paguidelines

  24. Comparison of age-adjusted prevalence estimates from the 2008 Physical Activity Guidelines and the Healthy People 2010 objectives, BRFSS - 2007 15.7%

  25. Difference in Estimates • Reasons for shift • Removal of frequency or duration requirement • Combination of minutes • Breakdown of shifts • 15.7% difference in prevalence estimates ► 5.4% - removal of frequency or duration requirement ► 4.3% - combination of moderate- and vigorous-intensity minutes ► 6.0% - for either reason

  26. Trends: 2008 Guidelines and Healthy People 2010 Criteria 17.2% 16.7% 15.7%

  27. Sodium and Hypertension

  28. Burden of Heart Disease and Stroke • Heart disease is the leading cause of death in the United States • Stroke is the third leading cause of death in the United States • In 2009, • ~ 785,000 people will have a new coronary attack • ~ 610,000 people will have a new stroke • Marked disparities persist Source: Lloyd-Jones D, et al. Heart Disease and Stroke Statistics—2009 Update: A Report From the American Heart Association Statistics Committee and Stroke Statistics Subcommittee. Circulation 2009;119:e21-e181.

  29. Salt and High Blood Pressure • Generally, higher consumption of salt means higher blood pressure • Sodium intake is related to levels of blood pressure and the prevalence of hypertension across populations • Within the span of a few weeks, most people experience a reduction in blood pressure when salt intake is reduced

  30. Salt and High Blood Pressure • The lower your blood pressure, the lower your risk of heart disease even if you do not have hypertension. • Decreasing sodium intake from 3,500 mg/day to 1,500 mg/day could lead to a 30% decrease in hypertension prevalence.* *Source: Joffres MR, Campbell NR, Manns B, Tu K. Estimate of the benefits of a population-based reduction in dietary sodium additives on hypertension and its related health care costs in Canada. Can J Cardiol 2007 May 1;23(6):437-43.

  31. Lower Pressure = Lower Risk Lower BP, Lower Risk Higher BP, Higher Risk Risk of ISD Death Systolic Blood Pressure Data Source: Lewington, Lancet 2002;360:1903-13, Using population risk estimates for ages 50-59 years old.

  32. Sodium Recommendation • 2005 Dietary Guideline recommendation: <2,300 mg/day • “Specific Populations” recommended to consume ≤1,500 mg/day • Hypertensive • Black • Middle or Older American • Average intake: 3,466 mg/day

  33. Too much sodium • The Loop. Crispy Chicken Salad w/ Lite Ranch • 722 kcal/ 1,527 mg of sodium • Panera Low-fat Chicken Noodle Soup • 160 kcal/ 1,670 mg of sodium • Little Caesars Slice of Pepperoni Pizza • 280 kcal/ 520 mg of sodium • Progresso Microwave Bowl of Minestrone Soup - 180 kcal/ 1,860 mg of sodium

  34. Is it Salt or Sodium? • Sodium Chloride is the chemical name for salt • 90% of the sodium we consume is in the form of salt • Other food additives contain sodium • Some amount of sodium is naturally occurring in foods

  35. Relative Amounts of Dietary Sodium in the American Diet Source: Mattes RD, Donnelly, D. Relative contributions of dietary-sodium sources. J Am Coll Nutr. 1991 Aug;10(4):383-93.

  36. International Perspective • Elevated blood pressure and high sodium intake are global issues • Sodium content of foods differ by country • Several countries have implemented strategies to reduce sodium intake

  37. Similar Foods Have Less Sodium in U.K. U.S. sodium/serving = 210mg U.K. sodium/serving = 160mg Slide borrowed from Dr. Angell, NYC U.S. sodium/serving = 220mg U.K. sodium/serving = 120mg

  38. Sodium Content Varies Widely Internationally U.K. U.S. Chicken Sandwich 830mg sodium (143g) Chicken Sandwich 640mg sodium (178g) 190mg more sodium per serving *Slide borrowed from Dr. Angell, NYC

  39. World Health Organization, 2007 Interventions should focus on three main pillars: • product reformulation(the main focus should be on the highest reduction possible in the salt content of commercialized foods and meals) • consumer(including improving nutritional education about the deleterious effects of excessive salt consumption on how to read the labels and choose healthier foods) • theenvironment(by building an environment where choosing the healthiest foods is the easiest and most affordable option to population groups at all socioeconomic levels).

  40. AMA Policy Recommendations • Minimum of 50% reduction of sodium in processed and restaurant foods over the next decade • Removal by the FDA of the GRAS status of sodium • Better sodium product labeling; warnings for foods high in sodium • Exploration by FDA of all options to reduce sodium • National consumer education initiative on sodium Source: Report 10 of the Council on Science and Public Health (A-06) Promotion of Healthy Lifestyles I: Reducing the Population Burden of Cardiovascular Disease by Reducing Sodium Intake

  41. Industry Response • Industry has voluntarily taken some action to reduce sodium • Several companies have salt workgroups • Increase in introduction of lower sodium foods • Some companies, such as Burger King, have made commitments

  42. CDC Activities to Lower Sodium Consumption • Ongoing Sodium Workgroup • IOM study • Aug 2008-May 2010 • Focus on means to reduce intake (regulation, labeling, education, incentives, health professional role, industry codes of conduct) • Tactics to address manufacturers, restaurants, grocers, schools, institutions) • Include implications for iodine deficiency • Comment/testimony on sodium as GRAS, labeling • Guidance to state DHDSP programs • Consultation with WHO and others
