Biostatistics: Understanding its role in public health

The key points mentioned here will help you understand the role of biostatistics in public health more efficiently.

Biostatistics is the field of applied statistics related to biology and medical science. Biostatisticians are responsible for gathering relevant data on health status, mortality, and morbidity in human populations and using it for public health practice. This data holds special significance for the healthcare organizations and authorities because it helps them to create the right strategies for the prevention of diseases.

Biostatisticians provide relevant data to healthcare experts to help determine the cause of targeted illnesses.

You should understand that the healthcare industry generates massive data daily. It is crucial to interpret and process this data to provide useful insights into the healthcare sector. That is where the role of biostatisticians comes into play, as they have to do statistical studies to produce accurate and meaningful data.

Usually, biostatisticians who perform this statistical analysis have expertise in statistical programs such as SAS and Excel. Also, expert biostatisticians create clinical trials to measure the impact of medications on patients and public health programs.

Read below to understand the role of biostatistics in public health.

1. Clinical Trials

With time, the medical industry is evolving continuously, and as a result, new treatment methods are being innovated. A certain treatment method is tested under the supervision of medical experts to ensure it is safe and effective for public health use. 

The role of biostatisticians is crucial in these clinical trials because they design the study and choose appropriate data collection methods. Also, they eradicate any misleading or useless information from the data. 

The process of clinical trials is incomplete without the efforts of biostatisticians. So, it shows the significance of biostatistics in public health. Biostatisticians gather accurate and precise information allowing medical experts to draw the right conclusions. It helps them decide how a new medication for a particular illness will perform better than the existing one. 

2. Cancer Research and Chronic Diseases

Biostatisticians have played a key role in conducting research and gathering facts to understand better how and why cancer is developed. It has greatly impacted the public health sector because it has enabled health experts to develop ideas for treating cancer more effectively.

Biostatistical research includes different clinical trials, focusing on patients of different backgrounds suffering from cancer. This research has helped relevant medical experts to understand genetic markers that can increase or decrease the risk of different types of cancer in people.  

The role of biostatistics also holds significance in understanding the different factors that can cause chronic diseases. From heart diseases to stroke, findings of biostatisticians have helped to mitigate the risk of such types of conditions. 

3. Impact of Environmental Changes on Public Health

Biostatistics has also enabled health professionals to understand the impact of environmental changes on public health, such as air pollution and water contamination.

With the help of clinical trials and surveys, biostatisticians have found how hazardous waste materials can affect the population. In addition, they have discovered how these environmental changes can impact the overall climate and affect different communities worldwide.

4. Statistical Genetics and Human Growth

Biostatistics professionals in the field of statistical genetics use different statistical techniques to draw results based on genetic data. It provides valuable insights to the health experts on how genes affect or causes particular health conditions. 

The statistical analysis of genes helps health experts identify patients with a risk of developing dangerous health conditions. 

Biostatistics has also provided major benchmarks related to human growth and development. It has enabled medical experts to understand better how children grow and which factors can play a key role in healthy growth

It also helps experts understand what factors can stunt children’s growth, allowing them to come up with preventive measures. 

5. Data Collection and Analysis

The primary role of biostatistics in public health is collecting, interpreting, and analyzing relevant data. Most statistical studies include data analysis used to identify the areas of weaknesses in public health.

Biostatisticians play a crucial role in data management and use it for clinical research studies. They utilize statistical methods to interpret data and reports through visual representations such as graphs or tables. These reports usually indicate a specific trend or any unusual behavior occurring in the human population.

The interpretations of the data are also included in the reporting of clinical research. It is an important part of the collaborative process between biostatisticians and researchers.

The entire point of collecting relevant health data is to improve public health as well as the survival rate of patients. Survival statistics give an idea about the lifespan of terminally ill patients and how long they will live, so it helps to treat them accordingly. These statistics help to understand the chances of remission, best treatment option, and chances of living a disease-free life after treatment.

Biostatistics specialists carefully examine studies to provide reference data to the doctors and patients.

6. Evidence-based Medicine and Meta-analysis

Biostatistics in public health plays a crucial role in meta-analysis and systematic reviews of medical data. It helps in the development of evidence-based healthcare that impacts patient care positively.

Meta-analysis is a structured study that analyzes the previous medical research related to any specific topic. To draw conclusions from these studies, integration of the individual results is required.

For example, meta-analysis evaluates if an individual has a risk factor for a disease or not. Also, it helps to figure out what kind of genetic and environmental factors can cause that disease. Eventually, it allows medical experts to decide what type of treatment will be suitable for the patient.


Biostatistics experts provide a quantitative review by analyzing and interpreting the relevant health data. The statistical analysis of this data helps healthcare experts determine whether current treatment methods are working effectively for targeted illnesses, allowing healthcare experts to improve the chances of patient survival through data-driven treatment.

The role of biostatistics in the current healthcare landscape holds special importance – whether it involves clinical trials, data collection and analysis, researching chronic diseases, etc.
