Does prevalence of disease increase as chronic disease increases. Prevalence is total no. of cases/total no. of risk factors of disease in the population over a period of time.
To determine whether the prevalence of a disease increases as chronic disease increases, you need to collect data on the number of cases and risk factors of the disease in the population over a period of time. Here's how you can approach it:
1. Define the population and time period: Decide on the specific population for which you want to study the prevalence of the disease. It could be a specific country, city, community, or any other defined group. Also, determine the time period for which you will collect the data.
2. Identify the disease: Specify the particular disease you want to investigate. This could be any disease of interest, such as diabetes, heart disease, cancer, etc.
3. Collect data on the number of cases: Gather information on the total number of diagnosed cases of the disease in the population during the specified time period. You can obtain this data from medical records, healthcare databases, or health surveys.
4. Gather data on risk factors: Determine the risk factors associated with the disease you are studying. Chronic diseases often have well-known risk factors, such as tobacco use, obesity, sedentary lifestyle, genetic predisposition, etc. Collect data on the prevalence of these risk factors in the population during the defined time period. This can be achieved through surveys, studies, or existing data sources.
5. Calculate prevalence: Calculate the prevalence of the disease using the formula: Prevalence = (Total number of cases of the disease / Total number of people at risk for the disease) x 100. The total number of people at risk is the population or sample you are studying, and it should exclude individuals who don't have the potential to develop the disease.
6. Analyze the relationship: Once you have the prevalence rate and the data on risk factors, examine the relationship between the prevalence of the disease and the presence of chronic disease risk factors. You can analyze this by comparing the prevalence rates among different subgroups based on the number of chronic disease risk factors they have.
By following these steps and analyzing the collected data, you will be able to determine whether there is a correlation between the prevalence of the disease and the presence of chronic disease risk factors in the population over the specified time period.
