Who doesn’t have health insurance?

There are multiple reasons why some individuals in the US have health insurance and others do not.  Affordability, knowledge of health insurance policies and awareness of need are just some reasons one may or may not have health insurance. To raise public awareness about the social determinants that increase one’s susceptibility to developing heart disease and stroke, in 2014 the CDC released a map of the percentage of adults in the US who are under the age of 65 and are uninsured. This map highlights areas of the country that are severely uninsured compared to areas where almost no one is without health insurance.

Do Socioeconomic Factors Influence Texans’ Decision to Get Vaccinated? – A cartographic Approach

Texas has one of the highest vaccination rates for childhood diseases overall, 97.4%, according to CDC. But the number of children not vaccinated because of their parents’ “personal beliefs”—as opposed to medical reasons—has risen since 2003, when such exemptions were introduced, to more than 44,000 so far in 2017 according to CDC. The 4:3:1:3:3:1:4 series is an overall measure that encompasses many vaccines that are recommended for children. Various demographic factors (sex, gender, race, availability of commercial health insurance) influence the decision to get vaccinated, were looked at.

The county-level data on the socioeconomic factors were obtained from US Census Bureau (American Factfinder). The health insurance data was obtained from Small Area Health Insurance Estimates (SAHIE). The vaccination rates were obtained from Texas Immunization registry through DSHS. The data was cleaned and geocoded to be analyzed in ArcGIS to produce maps as shown in Figure 1. Pearson’s correlation coefficient was used to analyze the relationship between vaccination rates and independent variable.

The non-vaccination rates are higher around the major cities of Dallas, Austin-San Antonio, Houston and some northwest Texas counties. Population density has a positive correlation with the non-vaccination rate. Other demographic factors have a positive correlation in certain counties as opposed to others.

The limitation on the immunization data is it being an optional registry so it would not be accurate to run statistics off this information to estimate an immunization rate. In future, it is productive to expand this concept to use regression analysis to try to find the odds of the relationship expressed in the maps and to find if there is a significant association.

Preventive Dental Care for Children in GA – A look at the disparities.

Preventive oral health care is essential for one’s overall health. For children, it is important to address oral health needs earlier in life to prevent oral health issues from forming and progressing into adulthood. Below is a map of the percentage of children in Georgia with financial access to preventive dental care. This map comes from an article written by Cao, Gentili, Griffin, Griffin & Serban (2017) titled, “Disparities in Preventive Dental Care Among Children in Georgia.”

The authors of the article state that financial access is, “the percentage of children who either are eligible for public insurance or have the ability to afford dental care through commercial insurance or ability to pay out-of-pocket,” (Cao et al., 2017). Although there are plenty of children who are eligible to receive public funding for preventive dental care in GA, only 27.9% of the 4,123 dentists in GA who offer preventive dental services to children accept public insurance, (Cao et al., 2017).

What are your thoughts? What does financial access to preventive dental care mean to you? Is this an accurate representation of financial access? I invite you to read more of the article on the CDC’s website, here
