Diabetes on rise in North Dakota
State still has relatively low prevalence percentage
Diabetes is an increasing challenge in North Dakota with the number of known people with diabetes growing in recent years.
However, North Dakota still ranks well below many other states in terms of both prevalence and recent increase in prevalence.
“I’ll say we’ve definitely noticed a steady increase in the need for services over decades,” said Sarah Howard, RN, BSN, diabetes educator with Trinity Health. “It goes back to 1994 and since then there has been a steady increase.”
According to the Centers for Disease Control and Prevention (CDC), 30.3 million Americans have diabetes and most states show a steady increase.
One recent study produced by website quotewizard.com, citing CDC data, asserted that North Dakota ranked No. 4 among states with and increase in people with diabetes over a 10-year period from 2007-2017.
However, according to the North Dakota Department of Health, studies such as that are intrinsically flawed.
“There was a significant change in the methods for collecting data… in 2011,” said Brianna Monahan, MS, RD, Diabetes Prevention and Control program coordinator, division of Health Promotion at NDDOH. “That said, I would look at a comparison of 2011 versus 2017. Using data pre-2011 is like comparing apples and oranges.”
Monahan said she would compare age-adjusted data instead of crude prevalence, which is what the quotewizard study used.
“Crude rates are influenced by the underlying age distribution of the state’s population,” Monahan said. “Even if two states have the same age-adjusted rates, the state with the relatively older population generally will have higher crude rates because diabetes is age-related. The age distribution of a population (the number of people in particular age categories) can change over time and can be different in different geographic areas. Age-adjusting the rates ensures that differences in prevalence from one year to another, or between one geographic area and another, are not due to differences in the age distribution of the populations being compared.”
Monahan pointed out that greater awareness can lead to an increase in rates because more people are being diagnosed.
“North Dakota has seen an increase in diabetes over the last several years; however, our overall rate of diabetes remains low compared to most of the country – we rank 18th, I believe,” Monahan said.
According to a NDDOH analysis of CDC data, North Dakota is ranked 37th among states when it comes to increase in prevalence from 2011-2017. The percentage was 7.5 in 2011 and it was 8.5 in 2017, a percentage point increase, according to data provided. Monahan said the median nationally is 9.1%.
“We’re nowhere near the top,” she said.
Only 12 states showed a decrease in prevalence during that time frame. Four states remained flat. West Virginia had the highest rate of increase among states at 2.2%.
“Our rate of increase is close to that being experienced in most states,” said Donna Amundson, Sanford Health’s director of Diabetes Center and certified diabetes nurse educator. “There is a higher rate of increase in certain parts of the country. In the Plains states, for example, the rate is influenced by the high rate among Native Americans.”
Several sources cited the high rate of diabetes among Native Americans for the statistical increase in North Dakota.
Typically, Howard said, the major risk factors are lifestyle (primarily diet and exercise), genetic factors associated with race and ethnicity, family history, age, high cholesterol and high blood pressure.
“There is also gestational diabetes, which can affect women, who have babies over nine pounds,” Howard said. “Diabetes is also more common in men.”
Amundson said that winter is a challenge in states such as North Dakota.
According to The State of Obesity, in 2017, North Dakota ranked 13th in the nation in adult obesity with a rate of 33.2%.
“You have to come up with creative ideas how to become more active in the winter,” she said. “Overall people work hard, but there are so many labor-saving devices that we don’t get as much exercise as we used to.”
Amundson added there are still many people who are under-insured or uninsured and thus are less likely to have access to the care they need.
If the increase in prevalence of diabetes is worrisome, pre-diabetes numbers border on alarming.
Howard said approximately 84.1 million people have pre-diabetes, which unchecked will often lead to diabetes.
“Many people don’t even know they have pre-diabetes,” Howard said. “Pre-diabetes doesn’t necessarily lead to diabetes, for which there is no cure. With pre-diabetes, monitored and addressed through lifestyle, it can be controlled. People with pre-diabetes have been able to control blood sugar and so avoided the onset of diabetes, although they will always be at risk.”
Howard advises that if, as part of an annual checkup, fasting lab results for glucose are up, particularly if there is family history, a patient should discuss it with his or her doctor.
