PubMed is a great source of journal article citations on most public health topics. It’s where I usually start. But there are many other article databases you should use, depending on your topic. Here are a few examples:
Embase is an international index including over 2,000 journals not in Medline/PubMed, as well as conference abstracts. Broad biomedical scope with strong coverage in drug, pharmaceutical, and toxicological research, including economic evaluations and healthcare policy & management. Includes a PICO search tool, as well as drug, device, and disease searches.
Global Health is a public health database particularly strong for finding articles from or about countries in the “Global South.” Topics such as environmental health, nutrition, infectious diseases, and more are covered.
Sociological Abstracts offers access to the international literature in sociology, demography, social psychology, and related disciplines in the social and behavioral sciences. If your research is on families, social relationships, peer groups, etc., you should try this database.
This is but a small sample of the databases offered by the UC Berkeley Library. For more public health databases, please visit our Databases in Public Health guide.
