Can you help me select an appropriate title for my research article?
Which of the following is an appropriate title for an article?
1. Are ABO blood groups related to overweight or obesity?: Based on 6 years of experience in two centers in Sulaimani Governorate, Kurdistan Region/ Iraq.
2. Association of ABO group types to overweight and obesity: Based on six years of experience in two centers in Sulaimani Governorate, Kurdistan Region/Iraq.
3. Possible links of blood group to obesity
The title of an article is important not only because it represents the summary of the paper, but also because electronic search engines or databases use words of the title. A good research paper title is usually typically 10–12 words long, and accurately highlights the core content of the paper by using descriptive terms.
Considering the above-mentioned criteria, option number 2 might be a preferred over the other two options you have suggested. However, a language edit would be required to improve the title.
