- Contracting Office Address The Department of Health and Human Services, National Institutes of Health, National Cancer Institute, Office of Acquisitions, 9609 Medical Center Drive, Rockville, MD 20850, UNITED STATES 1.0�� �DESCRIPTION The Division of Cancer Epidemiology and Genetics (DCEG), Metabolic Epidemiology Branch, plans to procure, on a sole source basis, from Harvard College President & Fellows, Harvard T.H. Chan School of Public Health, 677 Huntington Ave, Boston, MA 02115. The response close date of the notice for this requirement is in accordance with FAR 5.203(b). This acquisition will be processed under FAR Part 12 - Acquisition for Commercial Items and will be made pursuant to the authority in FAR Part 13.106-1(b)(1)(i); and is exempt from the requirements of FAR Part 6. The North American Industry Classification System code is 541715 and the small business size standard is 1,000 employees. It has been determined there are no opportunities to acquire green products or services for this procurement. 2.0�� �BACKGROUND Coffee is one of the most widely and habitually consumed dietary items worldwide. Consequently, there is sustained scientific and public interest in how coffee consumption impacts human health. Studies have reported both positive and inverse associations of coffee with risk of cardiovascular disease, but they have generally reported inverse associations with risk of diabetes, Parkinson Disease, depression and certain cancers, including liver, colorectal, endometrial, melanoma, and nonmelanoma skin cancer. Still, it is the association of coffee drinking with mortality that is particularly relevant when considering public health impact and dietary guidance. In general, studies have observed inverse associations with all-cause mortality, and in 2015 the Scientific Report of the Dietary Advisory Committee concluded that moderate coffee consumption (3 to 5 cups per day) could be a part of a healthy diet. Yet several important questions that may impact dietary guidance remain unresolved.� First, there is concern that coffee drinking may increase mortality among younger individuals. In 2013, a prospective study reported that coffee drinking was positively associated with mortality among individuals under the age of 55. Since most cohorts have included older populations and mortality rates are lower among younger age groups, few studies can replicate this finding. Second, existing studies have each had a limited number of cases among the highest consumption categories (e.g. ?6 cups/day) precluding stable risk estimates at the extreme end of the distribution particularly among never smokers who tend to drink less coffee. Coffee drinking and cigarette smoking are strongly positively correlated. Consequently, the impact of residual confounding is likely greater among the heaviest consumers. In the proposed study, we will limit our analytic population to never smokers to estimate the associations in the absence of residual confounding by smoking. Third, racial and ethnic minorities are largely under-represented in studies of coffee drinking and mortality. Given that patterns of coffee consumption vary considerably by race/ethnicity, it is important to assess associations in these subgroups. Fourth, only a few large cohort studies have considered causes of death beyond composite measures of cardiovascular disease and cancer. Finally, associations of coffee and morality risk have generally been similar by coffee type (e.g., caffeinated versus decaffeinated) and use of additives, but associations with cause-specific mortality have generally not been reported.� The Pooling Project of Prospective Studies of Diet and Cancer (DCPP) provides an opportunity to examine these issues in a large population with adequate sample size for well-powered analyses in key subgroups, including younger individuals and underrepresented racial/ethnic subgroups.� 2.1�� �Objective The primary objectives of this project are to: 1)�� �Provide stable estimates of the mortality risks across the entire range of low, moderate, high and very high coffee intake in a large, diverse analytic sample of never smokers. 2)�� �Assess whether coffee drinking is associated with pre-mature mortality. 3)�� �Evaluate mortality risks in key subgroups including racial and ethnic population subgroups. 4)�� �Explore associations of coffee drinking with mortality by type of coffee and use of common coffee additives. The Division of Cancer Epidemiology and Genetics (DCEG) will investigate associations of coffee drinking with all-cause and cause-specific mortality risk, including among key demographic subgroups. �The Division of Cancer Epidemiology and Genetics anticipates that the consortium approach, which affords a large diverse sample of never smokers, will yield unusually accurate and precise risk estimates that will clarify the dose response relationship of coffee drinking with mortality and inform public health nutrition guidance. 3.0�� �SCOPE The Contractor will conduct the analysis �Coffee drinking and mortality among never smokers in the Pooling Project of Prospective Studies of Diet and Cancer (DCPP)"". The Contractor shall be the leader of the DCPP and has full access to the data and harmonization code. In this role, the Contractor shall invite cohorts to participate in the project, harmonized coffee variables for participating cohorts, evaluate the availability of coffee additive data and harmonize coffee additive data currently in the DCPP database, harmonize mortality outcomes including all-cause mortality and leading causes of death, conduct pooled analyses to examine the associations between coffee consumption and all-cause and cause-specific mortality in never smokers and for key population subgroups. 4.0�� �CONTRACT REQUIREMENTS AND PERSONNEL QUALIFICATIONS� The Contractor shall work with the NCI TPOC to supervise the analysis of DCPP data.

TPOC: (TBD) 8.0�� �UNIQUE QUALIFICATIONS OF THE CONTRACTOR The vendor, Harvard T.H. Chan School of Public Health, is uniquely positioned to assure that the harmonization of coffee and mortality data and delivery of relative risk estimates for coffee and mortality in the consortium are consistent with prior research in the Pooling Project of Prospective Studies of Diet and Cancer (DCPP). The DCPP is a restricted access dataset, and only the vendor has full and direct access to the harmonized DCCP dataset, which has been built, updated, and maintained for over a decade using proprietary IP and SAS code. �The vendor is the only group that has collected and harmonized individual level data on diet and mortality from >30 cohorts within the NCI Cohort Consortium Cohorts. Analyses have previously been conducted in the DCPP on coffee consumption and risk of colon, renal cell, and pancreatic cancer. This project will build upon the data harmonized for those projects and on the statistical analyses conducted as well as on work currently being undertaken for projects examining associations between coffee consumption and risk of bladder and stomach cancer. Conducting all these analyses within the same consortium using exposures and covariates that have been harmonized using proprietary codes across over 30 cohorts will provide compatibility and consistency with past and future studies evaluating the health effects of coffee consumption. Conducting this project within the DCPP also provides consistency in the harmonization of mortality outcomes and analytic approaches used in the consortium as other mortality projects have been approved or are being proposed to be conducted within the consortium. In summary, the vendor is uniquely qualified to carry out the proposed research and the only vendor that can ensure consistency with past and future research on coffee and health in the NCI Cohort Conosortium. 9.0�� �SUBMISSION INSTRUCTIONS This notice is not a request for competitive quotations. However, if any interested party believes it can meet the above requirements, it may submit a proposal or quote for the Government to consider. The response and any other information furnished must be in writing and must contain material in sufficient detail to allow NCI to determine if the party can perform the requirement. �All responses and questions must be sent via email to the Contract Specialist, Dana Summons, at dana.summons@nih.gov by no later than 3:00 PM EST on July 25, 2024, (7/25/24). A determination by the Government not to compete this proposed requirement based upon responses to this notice is solely within the discretion of the Government.
