1. 1. The Growth of Food-Diet- Nutrition Literature in PubMed This slide set is based on a poster presented at the Medical Library Association annual meeting in Austin, Texas, in May 2015. Go to the next slide to see the poster. Xiaomei Gu, MSLS, Janna C. Lawrence, MLIS, Eric Rumsey MLS
2. 2. For details about the poster, and how this slide set is related to it, go to the next slide.
3. 3. The charts and introductory information at the top of the poster are on the next 3 slides. Its helpful to look at this before going ahead to the slides that follow, which are expanded versions of the charts for the individual food-diet- nutrition subjects on the poster. All of the images that accompany the charts are licensed for educational use; rights information is given for all images at the end of the slide set.
4. 4. All citations vs Fruit We have discovered that for many food-diet-nutrition (FDN) subjects, the growth in citations in PubMed increased greatly about 1990. For our study, we searched PubMed for FDN- related words in the article title, and compared this to the growth rate for all citations in PubMed (all searches were limited to human subjects). The chart below shows the growth rate for fruit (orange) and for all citations (grey). This shows that the growth rate for fruit remained essentially flat until about 1990, then began its rapid rise.
5. 5. All citations vs Vegetables Searching for vegetables shows a similar pattern, remaining fairly flat until about 1990, then beginning to rise.
6. 6. All citations vs Heart As a control, we also searched for general medical words. They generally showed a growth pattern similar to all citations, as shown below for heart. The slides that follow show the citation growth rate for a variety of food-diet- nutrition related subjects. They all have a pattern similar to fruit and vegetables, with increasing growth after about 1990.
7. 7. Soft Drink For reference, the charts below show the rapid rise in citations for fruit & vegetables after 1990 (about half way across the charts). Heart is representative of general medical subjects, which have grown at about the same rate as all citations in PubMed.
