Abstract text
Background and Objectives: Under- and over-nutrition negatively affect the health and development of individuals and communities. Evidence-based interventions addressing nutritional risk factors contribute to ameliorating these effects. The Cochrane Diet and Nutrition subfield of the PHC Field was formed in 2005 with the key goal of supporting the preparation of nutrition reviews, which are currently widely distributed across Review Groups. One of its original aims was to establish a specialized register of nutrition trials but this has not yet been realized. We propose establishing a Cochrane Diet and Nutrition Trials Register with the following specific objectives: • Provide a comprehensive repository of randomized controlled trials (RCTs) and controlled clinical trials (CCTs) assessing the effectiveness of diet and nutritional interventions for systematic review authors and other stakeholders. • Provide a resource to study the epidemiology of nutrition trials and identify knowledge gaps for future research. Methods: Studies will be included in the register if they meet the eligibility criteria outlined in table 1, regardless of publication status. We will develop a search strategy, and conduct an initial comprehensive search of all relevant sources, including CENTRAL, MEDLINE, EMBASE, and other electronic databases recommended by nutrition experts. No time or language limits will be used. We will assess eligibility through screening of abstracts, or full-text articles if necessary. Another investigator will conduct a quality check on a sample of the data. We will store citations in Microsoft Access 2007, coding them as RCTs or CCTs. Conclusions: We will collaborate with individuals and groups within and outside of the Collaboration in the development of this work. Immediate challenges identified include: • Development and validation of a comprehensive search strategy with a filter for nutrition trials. • Identify funding for developing and maintaining the register.
