HEALTHY PEOPLE 2000 The Public Health Service (PHS) is committed to achieving the health promotion and disease prevention objectives of "Healthy People 2000," a PHS-led national activity for setting priority areas. This RFA, Innovative Approaches to Prevention of Obesity, is related to one or more of the priority areas. Potential applicants may obtain a copy of "Healthy People 2000" (Full Report: Stock No. 017-001-00474-0 or Summary Report: Stock No. 017-001-00473-1) through the Superintendent of Documents, Government Printing Office, Washington, DC 20402-9325 (telephone 202-512-1800). ELIGIBILITY REQUIREMENTS Applications may be submitted by domestic and foreign, for-profit and non-profit organizations, public and private, such as universities, colleges, hospitals, laboratories, units of State and local governments, and eligible agencies of the Federal Government. Racial/ethnic minority individuals, women, and persons with disabilities are encouraged to apply as Principal Investigators. MECHANISM OF SUPPORT This RFA will use the National Institutes of Health (NIH) research project grant (R01) award mechanism. Responsibility for the planning, direction, and execution of the proposed project will be solely that of the applicant. Awards will be administered under NIH grants policy as stated in the NIH Grants Policy Statement. Applicants from institutions that have a General Clinical Research Center (GCRC) funded by the NIH National Center for Research Resources may wish to identify the GCRC as a resource for conducting the proposed research. If so, a letter of agreement from either the GCRC program director or principal investigator should be included with the application. This RFA is a one-time solicitation. Future unsolicited competing continuation applications will compete with all investigator-initiated applications and be reviewed according to the customary peer review procedures. The total requested project period for an application submitted in response to this RFA may not exceed three years. In keeping with the pilot nature of these studies, grants will be limited to $125,000 in direct costs in the first year and a maximum of $375,000 in direct costs over a three year period. The anticipated award date is September 30, 1999. FUNDS AVAILABLE For the initial year of funding, approximately $2,400,000 will be committed to fund applications submitted in response to this RFA. It is anticipated that 12 to 15 awards will be made. However, this funding level is dependent upon the receipt of a sufficient number of applications of high scientific merit. Although this program is provided for in the financial plans of the NIDDK, NHLBI, NIA, NICHD, ORWH and ODP, the award of grants pursuant to this RFA is also contingent upon the availability of funds for this purpose. RESEARCH OBJECTIVES Background The prevalence of obesity has increased dramatically over the past 10 years across virtually all populations and age groups. Over 50 percent of adult Americans are now either overweight (BMI greater than 25.0) or obese (BMI greater than or equal to 30.0) (Flegal et al, 1998). Twenty-five percent of U.S. children are overweight or at risk of becoming overweight and this number also has been increasing rapidly (Troiano and Flegal, 1998). In addition, obesity disproportionately affects many minority populations and some lower income groups (NHLBI and NIDDK, 1998). Obese individuals experience numerous adverse health consequences including increased risk for cardiovascular disease, diabetes, stroke, some cancers, osteoarthritis, sleep apnea, gallbladder disease, and higher mortality rates from all causes than normal weight people (NHLBI and NIDDK, 1998). In addition, the higher prevalence of obesity in minority populations and individuals with lower income and education levels contributes to excess disease and mortality rates experienced by these groups. Weight loss interventions are costly, difficult, and often unsuccessful at long-term maintenance of weight loss. In addition, it is unknown if weight loss in those individuals already obese reduces disease risk to the same level as that observed in those who were never obese (Andres et al, 1993; Williamson et al, 1995). Current estimates of the cost of obesity approach $100 billion per year (Wolf and Colditz, 1998), a cost projected to increase as the number of obese individuals in the population increases and as those who are currently obese suffer increased consequences of obesity-related comorbidities. Taken together, all these factors make the prevention of obesity a public health imperative. Obesity is a complex condition that results from interaction of genetic, behavioral, and environmental factors. Family studies and recent advances in understanding of the molecular genetics of obesity have made it clear that genetic factors predispose certain individuals to develop obesity and its comorbidities (Comuzzie and Allison, 1998). Behavioral and environmental factors that may contribute to obesity include: the increased availability of convenient, palatable, and inexpensive high energy density foods; increased sedentary behavior and decreased opportunity for physical activity; and psychosocial and cultural factors such as family environment (Hill and Peters 1998). Epidemiological studies have observed that specific stages of life confer high risk for the development of obesity in susceptible individuals. These include: the prenatal period, the period of adiposity rebound in childhood, adolescence, marriage, early adulthood, postpregnancy, and menopause. Health-related behaviors (e.g., smoking cessation or initiating use of prescription drugs such as corticosteroids) may confer risk of weight gain as well (Gill, 1997). Many minority populations, individuals of low socioeconomic status, and individuals with a family history of obesity also are at high risk for developing obesity. Prevention of obesity in childhood is a particularly important issue. Because persons who become obese as children are more likely to be obese as adults (Dietz, 1998) and because obesity in parents is a major risk factor for the development of obesity in their offspring (Whitaker et al., 1997; Whitaker and Dietz, 1998), these patterns may amplify the problem of obesity in the future. Family-based interventions offer the opportunity to provide integrated treatment and prevention interventions to multiple family members, an approach that also may strengthen social support aspects of intervention. For example, one study has reported reduction in the progression of obesity 10 years after treatment of obese children in a family oriented program (Epstein et al, 1990). A recent review of obesity treatment in children (Epstein et al, 1998) has proposed a number of research opportunities in this area, including research on behavior change and relapse behavior, methods to individualize treatment based on theoretical constructs, and energy balance regulation. Although a few studies have tested obesity prevention interventions in children, they have been too short-term to be able to make conclusions (Fitzgibbon et al., 1995; Stolley and Fitzgibbon, 1997). Prevention-oriented interventions have been conducted primarily in school-based studies (Donnelly, 1996). However, major school-based research interventions have generally been aimed at fostering healthy lifestyles by focusing on cardiovascular factors, physical fitness, substance abuse, and general nutrition, rather than on obesity prevention. For instance, the Child and Adolescent Trial for Cardiovascular Health (CATCH) succeeded in increasing students' physical activity in physical education classes, as well as improving knowledge and selection of healthful food choices, but did not result in BMI or skinfold thickness differences between treatment groups (Luepker, et al., 1996). While obesity treatment in adults frequently produces significant weight loss, long-term maintenance of weight loss remains a major challenge. A small number of obesity prevention studies have been conducted in adults. A few community- based studies have attempted to prevent weight gain in adults by altering the environment. Two community studies (Minnesota Heart Health Program, Stanford Five City Study) did not succeed in preventing weight gain, while in the Pawtucket Heart Health Program, BMIs in intervention communities were held constant compared to weight gains in control communities. The Pound of Prevention Study, a three-year randomized, controlled population-based study of obesity prevention using low intensity interventions (newsletters and semiannual classes) in adults, achieved increased knowledge in the intervention groups. However, the study was not able to demonstrate significant differences in weight gain between the intervention and control groups (Jeffrey and French, in press). The need for an obesity prevention initiative has been recognized by a number of NIH advisory groups. In 1994, the National Task Force on Prevention and Treatment of Obesity developed a long range plan focused on prevention of obesity (National Task Force on Prevention and Treatment of Obesity, 1994) and recently reaffirmed obesity prevention as a priority area for clinical research. The recently issued NHLBI/NIDDK Clinical Guidelines on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults include a discussion of the importance of preventing obesity and suggestions for strategies to be attempted (NHLBI and NIDDK, 1998). The International Life Sciences Institute sponsored a review of The Causes and Health Consequences of Obesity in Children and Adolescents (ILSI, 1998) as part of its Physical Activity and Nutrition Program for Children and Adolescents. This review includes recommendations for research on obesity prevention. The February 1998 NHLBI Report of the Task Force on Behavioral Research in Cardiovascular Lung and Blood Health and Disease also has recommended development of obesity prevention research efforts (NHLBI 1998). Research Goals and Topics This RFA responds to the need for systematic studies of obesity prevention. The sponsoring organizations encourage submission of grants for innovative pilot studies to prevent obesity in high risk individuals, families, or populations. For purposes of this RFA, prevention of obesity includes the primary prevention of overweight and/or obesity, the prevention of additional weight gain or increase in body fat in those already overweight and/or obese, and prevention of weight regain following weight loss. It is intended that the three years of funding provided for these pilot studies will allow 18-24 months of treatment and/or follow-up to be included in the proposed study designs. Applications should address: the content of the intervention (e.g., relative focus on aspects of diet, physical activity, both, or other factors), the setting of the intervention (e.g., in health care settings, community groups, social groups, home, school), and the method of intervention delivery (e.g., individual, group, computer-aided, internet-based, mass media). Novel or innovative aspects and the rationale for their use should be highlighted. The examples listed below are illustrative, and are not meant to comprise an exhaustive list. It is expected that additional important strategies and topics will be identified by investigators who respond to this RFA. Theory-based interventions are encouraged; however, due to the pilot nature of these projects and the need to explore innovative approaches, "experience-based" interventions not based on formal theory and other less well-developed concepts will be considered if they are well-justified. Examples of topics that can be addressed in pilot studies include: -- Interventions for high-risk populations, defined by family history, genetic characteristics, demographics, life transitions/stages (e.g., during smoking cessation or during the postpartum period), or other factors. -- Interventions to prevent increased incidence of overweight in young and middle-age adults -- Interventions for individuals at high risk of obesity based on behavioral or metabolic factors, e.g., fat preference, eating behaviors, behavioral response to caloric restriction, resting metabolic rate -- Interventions delivered in primary care settings -- Interventions that integrate obesity treatment and prevention in high-risk families -- Interventions that incorporate unique cultural and social features specific to special populations defined by race/ethnicity and/or socioeconomic status -- Interventions that are community-based or based on partnerships with community organizations, for example, schools, clubs, churches, work-sites -- Interventions to prevent weight regain after weight loss -- Comparisons of behavioral approaches for obesity prevention or maintenance of long-term weight loss -- Innovative nutrition and physical activity education programs to promote behavior change -- Interventions incorporating new knowledge of child development, learning, and psychobiology -- Interventions incorporating learning theory, e.g., response extinction and recovery -- Prevention or treatment of binge-eating disorders as a means of preventing obesity -- Interventions to increase physical activity and/or decrease inactivity as a means of preventing obesity -- Identification of factors which may contribute to differences among age-groups (including older persons age 65 years and older) in the safety and efficacy of exercise interventions to prevent weight gain -- Environmental interventions that address societal contributors to over- consumption of calories and barriers to increased physical activity. These could include interventions directed at food marketing practices, food labeling, subsidization of healthy food consumption practices, transportation patterns, opportunities for physical activity, and urban design to promote physical activity. -- Interventions incorporating weight loss medications to prevent weight regain after weight loss -- Interventions to prevent weight gain in individuals undergoing long-term treatment with medications, such as psychotropic agents, that are associated with weight gain SPECIAL REQUIREMENTS o Applicants should include plans to assess the feasibility of the intervention for long-term use by the target population. This process evaluation should address adherence, acceptability, and ease of delivery of the intervention. It is anticipated that some interventions may be ongoing up to the point of assessment, whereas others may include a brief, defined intervention with post- intervention follow-up at a later time; however, applicants are encouraged to assess program effectiveness at least 18-24 months from the beginning of the intervention. o Applicants should state their willingness to participate in one-day annual meetings and a final workshop to track progress of studies and promote exchange of experiences and ideas. Attendees will include the grantees funded under the RFA and investigators from obesity prevention studies receiving other funding from NIH. Funds for travel to the Washington D.C. area for the principal investigator (and coinvestigator, if appropriate) should be included in the budgets for each year. o The grants to be funded under this RFA are intended to serve as pilot studies that may be developed into clinical trials if appropriate, or to gather data on feasibility of new approaches that may lead to a pilot clinical study. o It is expected that proposed studies will include a control group. o Eligibility criteria and recruitment strategies should be well-specified. o Primary outcomes should be clearly justified and should include a measure of weight. Secondary outcomes relating to metabolic and/or physical fitness independent of weight loss also should be assessed where feasible. Applicants also may evaluate the effects of intervention on other factors such as body composition (e.g., percent body fat, bone density, visceral adiposity). o Psychosocial influences that may influence successful behavioral change should be assessed if possible (e.g., knowledge, attitudes, body image, social support, self-efficacy, quality of life, etc.). INCLUSION OF WOMEN AND MINORITIES IN RESEARCH INVOLVING HUMAN SUBJECTS It is the policy of the NIH that women and members of minority groups and their sub-populations must be included in all NIH supported biomedical and behavioral research projects involving human subjects, unless a clear and compelling rationale and justification is provided that inclusion is inappropriate with respect to the health of the subjects or the purpose of the research. This policy results from the NIH Revitalization Act of 1993 (Section 492B of Public Law 103-43). All investigators proposing research involving human subjects should read the "NIH Guidelines For Inclusion of Women and Minorities as Subjects in Clinical Research," which was published in the Federal Register of March 28, 1994 (FR 59 14508-14513), and in the NIH Guide For Grants and Contracts, Vol. 23, Number 11, March 18, 1994, available on the web at: https://grants.nih.gov/grants/guide/notice-files/not94-105.html. Investigators may also obtain copies from these sources or from the program staff or contact person listed under INQUIRIES. Program staff may also provide additional relevant information concerning the policy. INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN SUBJECTS It is the policy of NIH that children (i.e., individuals under the age of 21) must be included in all human subjects research, conducted or supported by the NIH, unless there are scientific and ethical reasons not to include them. This policy applies to all initial (Type 1) applications submitted for receipt dates after October 1, 1998. All investigators proposing research involving human subjects should read the "NIH Policy and Guidelines on the Inclusion of Children as Participants in Research Involving Human Subjects" that was published in the NIH Guide for Grants and Contracts, March 6, 1998, and is available at the following URL address: https://grants.nih.gov/grants/guide/notice-files/not98-024.html LETTER OF INTENT Prospective applicants are asked to submit, by March 26, 1999, a letter of intent that includes a descriptive title of the proposed research; the name, address, and telephone number of the Principal Investigator; the identities of other key personnel and participating institutions; and the number and title of the RFA in response to which the application may be submitted. Although a letter of intent is not required, is not binding, and does not enter into the review of a subsequent application, the information that it contains allows NIH staff to estimate the potential review workload and avoid conflict of interest in the review. The letter of intent is to be sent to: Barbara Harrison, M.S. Division of Digestive Diseases and Nutrition National Institute of Diabetes and Digestive and Kidney Diseases 45 Center Drive MSC 6600 Bethesda, MD 20892-6600 Telephone: (301) 594-8858 FAX: (301) 480-8300 APPLICATION PROCEDURES The research grant application form PHS 398 (rev. 4/98) is to be used in applying for these grants. These forms are available at most institutional offices of sponsored research and may be obtained from the Division of Extramural Outreach and Information Resources, National Institutes of Health, 6701 Rockledge Drive, MSC 7910, Bethesda, MD 20892-7910, telephone 301-710-0267, email: grantsinfo@nih.gov. The RFA label available in the PHS 398 (rev. 4/98) application form must be affixed to the bottom of the face page of the application. Failure to use this label could result in delayed processing of the application such that it may not reach the review committee in time for review. In addition, the RFA title and number must be typed on line 2 of the face page of the application form and the YES box must be marked. Submit a signed, typewritten original of the application, including the Checklist, plus five signed photocopies, in one package to: CENTER FOR SCIENTIFIC REVIEW NATIONAL INSTITUTES OF HEALTH 6701 ROCKLEDGE DRIVE, ROOM 1040, MSC 7710 BETHESDA, MD 20892-7710 BETHESDA, MD 20817 (for express/courier service) Applications must be received by April 27, 1999. If an application is received after that date, it will be returned to the applicant without review. The Center for Scientific Review (CSR) will not accept any application in response to this RFA that is essentially the same as one currently pending initial review, unless the applicant withdraws the pending application. The CSR will not accept any application that is essentially the same as one already reviewed. This does not preclude the submission of substantial revisions of applications previously reviewed, but such applications must include an introduction addressing the previous critique. REVIEW CONSIDERATIONS Applications that are complete and responsive to the RFA will be evaluated for scientific and technical merit by an appropriate peer review group convened in accordance with NIH peer review procedures. As part of the initial merit review, all applications will receive a written critique and undergo a process in which only those applications deemed to have the highest scientific merit will be discussed, assigned a priority score, and receive a second level review by the National Diabetes and Digestive and Kidney Diseases Advisory Council; the National Heart, Lung, and Blood Advisory Council; the National Advisory Council on Aging; or the National Advisory Child Health and Human Development Council. Review Criteria The goals of NIH-supported research are to advance our understanding of biological systems, improve the control of disease, and enhance health. In the written comments, reviewers will be asked to discuss the following aspects of the application in order to judge the likelihood that the proposed research will have a substantial impact on the pursuit of these goals. Each of these criteria will be addressed and considered in assigning the overall score, weighting them as appropriate for each application. Note that the application does not need to be strong in all categories to be judged likely to have a major scientific impact and thus deserve a high priority score. For example, an investigator may propose to carry out important work that is not innovative but is essential to move a field forward. o Significance: Does this study address an important problem? If the aims of the application are achieved, how will scientific knowledge be advanced? What will be the effect of these studies on the concepts or methods that drive this field? o Approach: Are the conceptual framework, design, methods, and analyses adequately developed, well-integrated, and appropriate to the aims of the project? Does the applicant acknowledge potential problem areas and consider alternative tactics? o Innovation: Does the project employ novel concepts, approaches or method? Are the aims original and innovative? Does the project challenge existing paradigms or develop new methodologies or technologies? o Investigator: Is the investigator appropriately trained and well suited to carry out this work? Is the work proposed appropriate to the experience level of the principal investigator and other researchers (if any)? o Environment: Does the scientific environment in which the work will be done contribute to the probability of success? Do the proposed experiments take advantage of unique features of the scientific environment or employ useful collaborative arrangements? Is there evidence of institutional support? In addition to the above criteria, in accordance with NIH policy, all applications will also be reviewed with respect to the following: o Adequacy of plans to include both genders, minorities and their subgroups, and children as appropriate for the scientific goals of the research. Plans for the recruitment and retention of subjects will also be evaluated. o Reasonableness of the proposed budget and duration in relation to the proposed research. o Adequacy of the proposed protection of humans, animals, or the environment, to the extent that they may be adversely affected by the project proposed in the application. The initial review group will also examine the provisions the safety of the research environment. o Availability of special opportunities for furthering research programs through the use of unusual talent resources, populations, or environmental conditions in other countries which are not readily available in the United States or which provide augmentation of existing U.S. resources. AWARD CRITERIA The anticipated date of award is September 30, 1999. Award criteria that will be used to make award decisions include: o Scientific and technical merit as determined by peer review o Availability of funds o Programmatic priorities o Availability of appropriate high risk populations for study, including racial and ethnic minorities, and under-served populations.

Research applications are encouraged that investigate the prevention and clinical treatment of these serious disorders, as well as their underlying brain and behavioral substrates. Studies are needed on the prevention of weight gain and obesity commonly observed in patients who are given psychotropic medication. NIMH is very interested in studies on the prevention of eating disorders such as recurrent binge eating, or compulsive dieting, since many of these individuals also suffer from bulimia nervosa and anorexia nervosa. Investigators interested in NIMH programs supporting studies of eating disorders may contact: Benedetto Vitiello, M.D., Division of Services and Intervention Research National Institute of Mental Health Telephone: (301) 443-4283 FAX: (301) 443-4045 Email: bvitiell@nih.gov AUTHORITY AND REGULATIONS This program is described in the Catalog of Federal Domestic Assistance No. 93.848, 93.837, 93.866, and 93.865. Awards are made under authorization of the Public Health Service Act, Title IV, Part A (Public Law 78-410, as amended by Public Law 99-158, 42 USC 241 and 285) and administered under PHS grants policies and Federal Regulations 42 CFR 52 and 45 CFR Part 74. This program is not subject to the intergovernmental review requirements of Executive Order 12372 or Health Systems Agency review. The PHS strongly encourages all grant and contract recipients to provide a smoke- free workplace and promote the non-use of all tobacco products. In addition, Public Law 103-227, the Pro-Children Act of 1994, prohibits smoking in certain facilities (or in some cases, any portion of a facility) in which regular or routine education, library, day care, health care or early childhood development services are provided to children. This is consistent with the PHS mission to protect and advance the physical and mental health of the American people. References Andres R, Muller DC, and Sorkin JD.
