Gestational Diabetes

The percentage of American adults who have ever been diagnosed with gestational diabetes is relatively low, but there are some significant differences between states.  Some states with relatively high gestational diabetes numbers (CA for instance) are below average in the percentage of adults with Type 2 diabetes.

Diabetes in America

As Americans have grown fatter, the percentage of adults with diabetes has also risen.  Diabetes involves the inability of the body to process sugars derived from the foods we eat.  Type 1 (AKA childhood diabetes) is inborn where a child's body lacks the ability to produce enough insulin.  Type 2 (AKA adult onset diabetes) usually involves obesity where a steady diet of sugar, carbohydrates and other such foods have burnt out the body's ability to produce enough insulin and/or created a condition where the body's cells have developed resistance to insulin.

Another kind of diabetes develops among some pregnant women -gestational diabetes.  Diabetes is an inflammatory disease and some recent studies point the possibility that Alzheimer's disease is actually Type 3 diabetes.

In more than a fifth of states -12 to be exact- the percentage of diabetic adults has now risen to more than 10%.

Fat in America

Happy New Year!  The start of a new year is often also the start of a new diet or health plan for many Americans.  The holidays have come and gone and left many with a few extra pounds.  So I thought today would be a good day to look at what else -obesity data!

Measuring obesity is somewhat complicated.  Because it is a relatively easy measure to gather, most survey data -including the CDC's Behavioral Risk Factor Surveillance Survey (BRFSS) data- use people's height and weight to calculate their Body Mass Index (BMI).  It is far from a perfect measure.  If you really are "big boned" as the country saying goes or are muscular, you may have a higher BMI but not be overweight. Or, you might come from an ethnicity of smaller framed people and rate as underweight when you are actually a healthy weight.  Still, for most people, the BMI is a relatively accurate measure of obesity.

The CDC breaks overweight people into the categories of Overweight (see above) and Obese (see below). Overweight people have a BMI of 25 to 29.9.  Obese people have a BMI of 30 or higher.  Being overweight puts you at risk for a shorter life, heart disease, diabetes, knee problems, and even psychological issues related to stigma against the overweight.

You'll notice that some states have relatively high percentages of people who are overweight but not that high of percentages of people who are obese.  Arizona stands out with this pattern.  Mississippi -which leads the country in the highest percentage of overweight and obese adults- has a relatively low percentage of people who are overweight in part because so many adults have transitioned into the obese category.

Even while obesity has risen across the country, a general pattern has emerged where the western states and northern tier states are relatively thinner than the South.

Where Have Smoking Cessation Programs Had the Biggest Impact?

In this continuing series on health data, let's look today at smoking.

The CDC lists smoking as the #1 preventable cause of early death.  Around 40% of people who smoke will eventually develop some type of health problem related to smoking.  Thus, smoking cessation and prevention programs for decades have -successfully I might add- greatly reduced the number of Americans to smoke.

In looking at data from the CDC's Behavioral Risk Factor Surveillance Survey (BRFSS) of adult health behaviors, I was curious if there were any regional differences showing where smoking cessation programs have had the biggest impact.  And it appears the answer is YES! -specifically in New England and Arizona which so the biggest percentages of people who have quit smoking.  

Let's look at the maps individually:

In every state except two, most adults have never smoked.  Only in Kentucky and West Virginia do the number of current or former smoker exceed 50% (52% each actually).  I have kept the legend values the same on these 4 maps, however, for comparison purposes.

By 2010 the number of adults who smoke daily in every state is below 1 in 5 -except in West Virginia where daily smokers exceed 20% of the population.





Interestingly, most American adults who smoke also smoke daily.  Less than 10% of American adults report they smoke but only a few days a week.

This last map shows the key differences.  People in Utah are the least likely to ever smoke.  Thus, Utah also has the lowest percentage of former smokers -because fewer people ever started smoking.  In most of the rest of the country, the percentage of former smokers is somewhere between 20-30% of the adult population.  The key exceptions are VT, NH, ME, and AZ where a larger percentage of the population has stopped smoking.  All four of these states actually had higher percentages of adults who have smoked or currently smoke but have had more success in adults quitting.

Kentucky Lung Cancer Death Rates By County

Kentucky leads the country in the number of adults who smoke -a leading cause of lung and bronchus cancer.  Sadly, Kentucky also leads the country in lung and bronchus cancer deaths.  Within the state, however, there are big regional differences with the blue counties in southeastern Kentucky having the highest death rates from lung cancer.
