Deaths from malnutrition are rare in Minnesota, but they increased in the first year of the COVID-19 pandemic — primarily among women 85 and older living alone in rural areas.
The unexpected finding was part of a broader Mayo Clinic analysis of final death certificate data in 2020, when 10% of the state's 52,030 deaths were caused by COVID-19.
Social-distancing measures in Minnesota might have prevented hundreds or thousands of COVID-19 deaths, Mayo researchers said, but the resulting isolation contributed to the state's 123 malnutrition deaths that year. The state had averaged about 80 malnutrition deaths in the prior two years.
Older, rural Minnesotans lost contact with friends or relatives or support programs that brought them meals to maintain their health, said Dr. Rozalina McCoy, a Mayo primary care provider and lead author of the study.
"Churches went virtual. Food shelves closed or people were afraid to go to them," McCoy said. "So, it really was a death of social isolation. For me, in primary care, that was the saddest part."
The researchers also expected an isolation-related increase in deaths from unmanaged heart disease, cancer and stroke because patients in 2020 weren't going to clinics for regular care or hospitals for acute flareups. But that didn't happen. Suicides didn't increase, either, possibly because families were huddled together and young adults didn't have isolated moments in which to act on fleeting impulses of self-harm.
Mortality trends are viewed beyond a numerical count of deaths in years of potential life lost — a measure that is heavily influenced by young people who die from preventable causes. Minnesota's 12% increase in that measure in 2020 was driven beyond COVID by homicides involving firearms, drug overdoses, and liver diseases that often were related to alcohol abuse.
"It confirmed that a lot of people died from COVID and deaths of despair," such as overdoses, McCoy said. "It also confirmed what people have been seeing, and almost didn't believe, about (the lack of an increase in) deaths from chronic diseases or accidents or suicides."
