Both states easily exceeded the nation as a whole, with the overall USA suicide rate rising 25.4 percent. North Dakota saw the biggest increase as rates jumped 57.6 percent.
Suicide rates are up more than 30% in 25 states across the country.
"The data are disturbing", said Anne Schuchat, the CDC's principal deputy director. "From individuals and communities to employers and healthcare professionals, everyone can play a role in efforts to help save lives and reverse this troubling rise in suicide".
The CDC say the latest numbers show 45,000 people in America took their own lives in 2016, which was more than double the number of homicides that same year.
She said she found it interesting in a tragic way that of those who committed suicide without a known mental-health problem, 55 percent died by firearm. "Other problems often contribute to suicide, such as those related to relationships, substance use, physical health, and job, money, legal, or housing stress".
Suicide rates increased for all age groups under 75, but middle-aged adults aged 45 to 64 had the largest rate increase.
Suicide rates varied from 6.9 per 100,000 residents a year in the District of Columbia to 29.2 per 100,000 in Montana. DE had the lowest increase at 5.9 percent.
"Suicide does tend to rise during the holidays or at least that's what some early reports said".

Because it relies on Congress for funding, the CDC may have good reason not to emphasize the unique role of firearms in USA suicide rates.
"Our data show that the problem is getting worse", Schuchat said. "Every step feels like it's an uphill stretch, but you just keep going and keep going and eventually you get to that summit, and the view when you get there is just spectacular", he said.
Firearms were the most commonly reported method of suicides (48.5%), though decedents with known mental health conditions were less likely to die by firearm (40.6%) and more likely to use strangulation (31.3%) or poisoning (19.8%) than those without (26.9% and 10.4%, respectively). "So, when you put those things together, it can be hard to find help even when you want it", Trisha Kajimura, Mental Health America of Hawai'i Executive Director, said.
Health officials have attributed Massachusetts' low suicide rate to several factors: having few rural areas, so emergency and other medical services are nearby; a strong behavioral health system; good access to health care services with near-universal insurance coverage; a low rate of gun ownership; and a decade of suicide prevention activities. Suicide is now the tenth leading cause of death in the country, and one of only three on the rise, in addition to Alzheimer's and drug overdoses.
Yet research has shown that almost 80 per cent of people who die by suicide explicitly deny suicidal thoughts or intentions in their last communications, he added. "They might actually bring up specifically that they're thinking of suicide".
'Conditions like postpartum depression and menopause [may put some women at a higher risk], and, for women in general, stereotypes of being the ideal mom and employee, the stigma associated with a need to "balance" all of that can cause pressure as well, ' said Dr Ali.
