Re: The Framingham Heart Study, 0925-0216, Revision

Dear Sir or Madam,

The Academy of Nutrition and Dietetics (the "Academy") appreciates the opportunity to submit comments to the The National Heart, Lung and Blood Institute (NHLBI) of the National Institutes of Health (NIH) regarding its April 22, 2016 information collection for the Framingham Heart Study, 0925-0216, Revision. Representing over 90,000 registered dietitian nutritionists (RDNs),1 nutrition dietetic technicians, registered (NDTRs), and advanced-degree nutritionists, the Academy is the largest association of food and nutrition professionals in the United States and is committed to improving the nation’s health through food and nutrition across the lifecycle. Academy members independently provide nutrition care services, including Medical Nutrition Therapy (MNT),2 to individuals with a wide variety of disease states and chronic conditions, including cardiovascular disease (CVD) and risk factors of CVD.

Since 1948, the Framingham Heart Study has been exhaustively researching the leading cause of death in the United States and making significant contributions to the literature. The Academy strongly supports this extension of the Framingham Heart Study to examine the Generation Three Cohort, New Offspring Spouses, and Omni Group 2 Cohort, as well as to continue to monitor the morbidity and mortality which occurs in all Framingham Cohorts.

CVD onset can often be prevented and disease progression can be slowed with lifestyle modifications, such as diet. The multi-generational aspect of the Framingham Heart Study and enhanced diversity provided by the Omni cohorts make it unmatched in scientific rigor and result, generating more than 1200 scientific journal articles, with many discoveries related to diet. The inclusion of spouses is significant and will beneficially increase the amount of data available.3 All study participants or their relatives have been closely examined previously, and thus the study deals with a stable, carefully described group.

As the Framingham Heart Study notes, "[o]ver the years, careful monitoring of the Framingham Study population has led to the identification of the major CVD risk factors—high blood pressure, high blood cholesterol, smoking and lung cancer, obesity, diabetes, and physical inactivity—as well as a great deal of valuable information on the effects of related factors such as blood triglyceride and HDL cholesterol levels, age, gender, and psychosocial issues."4 The Academy, however, believes that traditional CVD risk assessment measures should also include LDL-cholesterol. Thus, although LDL-cholesterol is not presently part of the Framingham Heart Study, it is widely recognized as a better marker of atherosclerotic risk than total- or HDL-cholesterol, and is certainly a part of "traditional" approach to assessing and monitoring risk and should be included.5 The study should also include nontraditional CVD risk assessment measures that are considered good quality biomarkers of risk of CVD (or that are related to its development) and that can be reasonably targeted by lifestyle changes in this review's target population of adults without known CVD.

The Academy also particularly supports extension of the examination of the Omni Group 2 Cohort. Researchers need to know more about why heart disease is particularly prevalent among certain ethnic and racial groups, the cultural factors at play, participants' dietary habits, environmental triggers or influences, preventive program possibilities, and a better understanding of influences across cultural and ethnic groups. Based on the new information and research arising from this extension, we eagerly anticipate learning more about the genetic factors influencing CVD.

Conclusion

The Academy appreciates the opportunity to comment on the information collection regarding the Framingham Heart Study. We would be grateful for the opportunity to discuss these recommendations in greater detail in the near future with you. Please contact either Jeanne Blankenship at 312-899-1730 or by email at jblankenship@eatright.org or Pepin Tuma at 202-775-8277 ext. 6001 or by email at ptuma@eatright.org with any questions or requests for additional information.

Sincerely,

1 The Academy approved the optional use of the credential "registered dietitian nutritionist (RDN)" by "registered dietitians (RDs)" to more accurately convey who they are and what they do as the nation's food and nutrition experts. The RD and RDN credentials have identical meanings and legal trademark definitions.

2 Medical Nutrition Therapy is an evidence-based application of the Nutrition Care Process. The provision of MNT (to a patient/client) may include one or more of the following: nutrition assessment/re-assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring and evaluation that typically results in the prevention, delay, or management of diseases and/or conditions.
