Epidemiology, which deals with diseases and how they occur and impact the populations is a core area of public health as a field. In this field, you will constantly be in a position where you will be expected to conduct epidemiological studies or review a study that has already been carried out. So, do you know the basic procedures, which are needed to conduct a proper epidemiological investigation?

Here in this loose-leaf, let’s take you through the six main steps you need to follow to conduct an epidemiological study. This will not only help anybody reading this article who is in the process of developing their initial assignment but anybody working in public health in any capacity will benefit from learning these steps.

1. Define the Research Question

To make sense of all the data that is available, every epidemiologic study has a well-defined and specific question to start with. This step is basic as it serves as the framework for all the other steps that are taken into consideration. Your research question should be the following.

• Specific and well-defined
• Relevant to public health
• Possible to answer within your constraints

For instance, a refined question might look like “What is the relation between a high-fat diet and post-menopausal breast cancer risk?”

If you are having a problem coming up with a good research question, then you should go for Epidemiology Assignment Help to help in vetting the ideas so that you avoid going around in circles.

2. Select the Study Design

After coming up with your research question the next process is to determine the right study design. Some of the common epidemiological study designs include the following points below.

• Cross-sectional studies
• Case-control studies
• Cohort studies
• Randomized controlled trials

Every design has its advantages and disadvantages that are inherent in the design. The choice of the right one is critical to its output or rather the outcomes the test yields. In case you are confused regarding which design out of the two would be most appropriate for your research question, seeking Online Ecology Assignment Help helps reach the right conclusion.

3. Describe and Choose the Sampling Frame

Your study population should therefore be the group about which you wish to generalize your results. Consider the below points.

• Inclusion and exclusion criteria
• Sample size and power calculation
• Types of sampling (Random, stratified, cluster etc.)

However, make sure that the study population is well defined as this can result in yielding meaningful results. If students face any difficulties in solving such problems, then they should take an Epidemiology Homework Help for a better understanding of the given concept.

4. Collect Data

As with any epidemiological study, data collection is the lifeblood of your project. The following procedures come with this step.

• Developing data collection instruments (questionnaires, charts records review etc.)
• Ensure standardization of data collectors through training
• Implementing quality control measures

The process of data collection is very important to have a valid study. In case you are in doubt as to what is appropriate in an epidemiological data collection, may turn to internet Ecology Assignment Help services.

5. Analyse the Data

In epidemiologic research data analysis is sometimes carried out through the use of sophisticated statistical methodologies. Some of the key aspects are these as mentioned below are also documented:

• Descriptive statistics are used in data analysis to present your data.
• Non-parametric inferential statistics to analyse possible hypotheses
• Relative risk, odds ratio and other measures of association.
• Controlling for confounding variables

If you are scared of statistical analysis, then we would like to remind you that we have Epidemiology assignment help that will lead you through this very important step.

6. Interpret and Communicate Results

The last stage is concluding/interfering with the results obtained and presenting them in the right manner. This includes as found below.

• Placing your findings within the existing literature
• Review of the strengths and weaknesses of the study
• Mitigating bias and confounding factors
• Proposing implications for practice or policies in public health

Communication of results is very important, in other words, the effect of your study Thus, clear communication of results. Remember, if you require any help in writing a discussion section that will add more power to your writing, you can always get help from our online Ecology Assignment Help.

Hence, if you want to perform a sound epidemiological study, it will be advisable to embark on the following six steps. However, one must keep in mind that epidemiologic work is a very intricate activity, and one is sure to face some or other difficulties during the process. Do not wait to ask us to ‘write my Epidemiology assignment help’ or any Epidemiology Homework Help as and when required. These resources can help define the subject area, further evaluate your research question, and even help decipher a statistician’s results.

Epidemiology is a gradual process of learning and with every step that you take, you are on the way to becoming a professional public health personnel. Looking for more, never stop asking questions stay committed to public health, and learn that every figure out and jargon known in epidemiology is crucial to the field of public health.
