Flu Vaccination Prevalence, Puerto Rico 2016
Millions of people get the flu every year. Of these, hundreds of thousands of people are hospitalized and thousands or tens of thousands of people die from flu-related causes every year. A seasonal flu vaccine is the best way to reduce your risk of getting sick with flu and spreading it to others. When more people get vaccinated against the flu, less flu can spread through that community. (www.cdc.gov/flu)
The objective of this post is to provide insight into the prevalence of flu vaccination in Puerto Rico. This type of information can be useful for institutional strategies and activities such as: knowing how to best allocate human or economic resources toward flu vaccination, determining risk factors for the flu, developing scientific hypotheses for continued research into the disease’s etiology, or even developing strategies to increase flu vaccine uptake.
In an effort to survey many types of social, demographic, disease and behavioral outcomes in the United States and its associated territories, the Centers for Disease Control and Prevention (CDC) administers numerous population-based surveys. The information used to estimate flu vaccination prevalence in this report came from the 2016 version of the population-based survey regularly administered by the CDC known as the Behavioral Risk Factor Surveillance Survey (BRFSS). Flu vaccination prevalence is surveyed by the BRFSS using the following question: During the past 12 months, have you had either a flu shot or a flu vaccine that was sprayed in your nose
The complete methodology used to conduct the analyses shown in this post can be found here.
The following statistical remarks highlight the most meaningful differences among a selected group of demographic variables based on a logistic regression model. We encourage you to refer to the graphs and tables here for a more in-depth look at flu vaccination prevalence in Puerto Rico.
An estimated 687,165 (25.15%) adults in Puerto Rico had a flu vaccination in 2016. When evaluating flu vaccination by age group, adults aged 25-34 were half as likely to report having had a flu vaccination than those aged 18-24 while adults aged 65+ were twice as likely to report having had a flu vaccination. These differences in flu vaccination by age were significant (p-value < 0.05). Among all adults surveyed, There was no substantial difference in vaccine uptake between males and females in this sample.
In terms of education level, college graduates were 10% more likely to report having had a flu vaccination than the reference group (those who completed only some high school), although this difference was not significant. Those with an annual income of $15k-$25k were 20% less likely to report having had a flu vaccination than those whose annual income was less than $14,999 (p-value > 0.05). Those who reported never being married were 36% more likely to report having had a flu vaccination compared to those who were married (p-value < 0.05). Adults who classified themselves as being homemakers were 37% less likely to report having had a flu vaccination compared to those who reported being employed for wages (p-value < 0.05).
