Abstract

The thesis is based on quantitative cross-sectional and randomised intervention studies. The aim was to determine the prevalence of prediabetes and undiagnosed type 2 diabetes mellitus (T2DM) in North Iceland. Furthermore, it sought to compare the sensitivity and specificity of the Finnish Diabetes Risk Score (FINDRISK) combined with HbA1c levels and other measurement methods to identify individuals at risk of T2DM in Icelandic primary health care. The study also aimed to assess differences in health functioning and well-being between participants with and without T2DM risk. The intervention study examined the effects of nurse-led follow-up using the Guided Self-Determination (GSD) method to help individuals at risk of T2DM reduce their risk of coronary heart disease (CHD).

Data collection took place between 2020 and 2023 among individuals aged 18–75 residing in the catchment areas of three health centres in North Iceland.

Findings revealed that among the 220 participants, none had undiagnosed T2DM, but 13.2% showed indicators of prediabetes. The prevalence of overweight and obesity was high among participants. Both FINDRISK and the waist-to-height ratio may serve as useful screening tools for further T2DM risk assessment in primary care, allowing preventive support before prediabetes develops into disease.

Calculations of FINDRISK sensitivity and specificity showed an aROC of 0.814, and a threshold of ≥11 points was identified as appropriate for further investigation of T2DM risk.

Although no statistically significant difference was found between the intervention and control groups regarding reduced CHD risk following 12 weeks of nurse-led GSD counselling, participation in the intervention was associated with an 18% relative reduction in 10-year CHD risk.

Conclusions: A FINDRISK threshold of ≥11 points can be used as a benchmark for further T2DM risk assessment in primary health care. Although no significant group differences were found after the intervention, regular monitoring and GSD counselling appear to be beneficial in promoting overall reduction of coronary heart disease risk factors.
