Factors associated with knowledge of the disease in people with type 2 diabetes mellitus.
Verônica Rabelo Santana Amaral, Ícaro José Santos Ribeiro, Roseanne Montargil Rocha
PMID 33687806WHAT IT FOUND
54.7% of 412 adults with type 2 diabetes in Brazil had insufficient knowledge.
Age 60 or older, low education, low income, and never attending diabetes education groups were linked to this.
Key findings
0154.7% of the 412 analysed adults with type 2 diabetes had insufficient knowledge about diabetes.
02In adjusted analysis, insufficient knowledge was linked to never participating in an educational group, age 60 years or older, illiterate and primary education, and income of one minimum wage or less.
03Bivariate analysis found significant differences for age, living without a partner, education level, and family income.

What it does not show
The study measured knowledge and factors at one time, so it cannot show that educational groups, age, education, or income caused the knowledge difference. It was done in one municipality in Northeast Brazil with four primary care units, so it may not apply to other places or health systems. The paper reports different analysed numbers: methods says 413 after excluding 7, while results says 412 after losing 8. Clinical variables were self-reported, so diagnosis time, insulin use, physical activity, and follow-up may be inaccurate. The sample was mostly female (69.7%), aged 60 years or older (67.7%), and had elementary education (91.2%), so the findings mainly describe that group.
Declared interests
The paper reports no aids or subsidies.
The easy way to misread this
Do not conclude that diabetes education groups improve knowledge. This study measured knowledge at one time and found an association, not a cause.
