About Health Statistics

Health statistics are numbers that summarize information related to health. Researchers and experts from government, private, and non-profit agencies and organizations collect health statistics. They use the statistics to learn about public health and health care. Some of the types of statistics include:

  • How many people in the country have a disease or how many people got the disease within a certain period of time
  • How many people of a certain group have a disease. The groups could be based on location, race, ethnic group, sex, age, profession, income level, or level of education. This can help identify health disparities.
  • Whether a treatment is safe and effective
  • How many people were born and died. These are known as vital statistics.
  • How many people have access to and use health care
  • The quality and efficiency of our health care system
  • Health care costs, including how much the government, employers, and individuals pay for health care. It could include how poor health can affect the country economically
  • The impact of government programs and policies on health
  • Risk factors for different diseases. An example would be how air pollution can raise your risk of lung diseases
  • Ways to lower risk for diseases, such as exercise and weight loss to lower the risk of getting type 2 diabetes

Numbers on a graph or in a chart may seem straightforward, but that's not always the case. It's important to be critical and consider the source. If needed, ask questions to help you understand the statistics and what they are showing.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Health Statistics

20 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
