A working party from the Goulburn Valley Primary Care Partnership, located in rural Victoria, Australia, explored the literature for methods of measuring fruit and vegetable consumption, as part of a government funded initiative. Members of the working party are dispersed in various locations. The aim was to utilise the findings to inform the development of a survey and methodology to accurately measure baseline fruit and vegetable consumption in children, in each location of the working party members. Determining fruit and vegetable consumption of any population relies on accurate measurement methods. Eligibility criteria of the literature review was determined by the aims of the survey. Two members of the working party conducted the initial search of electronic databases, with the assistance of a librarian. The working party shared, reviewed, summarized and critiqued representative studies through electronic communication. The initial literature review yielded 176 articles. After deduplication, 67 met the eligibility criteria. Peer review reduced this to 14 most relevant articles to inform survey development and project methodology. Self reporting of fruit and vegetable consumption is complicated by the subjective understanding of respondents, resulting in over and under estimation. There is evidence that inclusion of photographs of serving size overcomes this limitation and improves accuracy. There were many other methodological confounders, such as seasonal variation of consumption, which had not been previously considered. The literature review provided valuable information for the development of a local survey. Previous research identified important pitfalls. The systematic and rigorous literature review conducted will ensure that our project avoids methodologies which result in inaccurate baseline data of fruit and vegetable consumption. |
