PRIVACY ACT STATEMENT: You have rights under the Privacy Act. The following statement describes how that Act applies to this study:

Authority: Authority to request this information is granted under Title 5, U.S. Code 136, Department of Defense Regulations, Executive Order 9396, DoD RCS#DD-HA(AR)2106 (expires 07/31/17), and OMB #0720-0029 (expires 07/31/17). Personal identifiers will be used to link survey data with medical and other military records.

Purpose: Medical research information will be collected in a research project titled "Prospective Studies of U.S. Military Forces: The Millennium Cohort Study." The project objective is to enhance basic medical knowledge and to improve the treatment and prevention of illnesses that may be related to military service.

Routine Uses: The information provided in this questionnaire will be maintained in data files at the Deployment Health Research Department at the Naval Health Research Center and used only for medical research purposes. Use of these data may be granted to other federal and non-federal medical research agencies as approved by the Naval Health Research Center's Institutional Review Board. However, your personal identifiers will be protected. By signing the original consent form, you volunteered to disclose your information as identified above. If you do not agree to this disclosure, your failure will make the research less useful. The "Blanket Routine Uses" that appears at the beginning of the Department of Defense's compilation of medical databases also applies to this system.

Anonymity: All responses will be held in confidence by the Deployment Health Research Department. Information you provide will be considered only when statistically summarized with the responses of others. Your personal identifiers (name, etc.) will only be used to link data sets and then the identifiers will be stripped from study data such that medical researchers cannot identify you individually.

Voluntary Disclosure: Completion of the questionnaire is voluntary. Failure to respond to any of the questions will NOT result in any penalties except possible lack of representation of your views in the final results and outcomes.

AGENCY DISCLOSURE NOTICE: The public reporting burden for this collection of information is estimated to average 45 minutes per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing the burden, to the Department of Defense, Washington Headquarters Services, Executive Services Directorate, Information Management Division, 4800 Mark Center Drive, East Tower, Suite 02G09, Alexandria, VA 22350-3100 (0720-0029) Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to any penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.
