Excess bodyweight is the sixth most important risk factor contributing to the overall burden of disease worldwide. Indeed, during the last two decades, obesity-related topics have been the subject of numerous studies. The objective of this study is to conduct a bibliometric analysis of all obesity-related publications in the category of nutrition and dietetics in Science Citation Index (SCI) from
Methods
In the 2004 edition of the Journal Citation Reports (JCR), 5968 journals are listed in the Science Citation Index (SCI). Of these, 53 journals covered the subject of nutrition & dietetics and were thus used in this study. A keyword search, using the following terms, was performed to identify obesity-related studies published between 1991 and 2004: obesity, obese, and overweight.
Results
The results indicated that ten document types were found in the total of 10,336 documents. English was the dominant language, comprising 99% of the articles.
