| Summary: | Greenlanders have a lower cardiovascular mortality and morbidity than Danes, possibly due to a lower blood pressure. However, 24-hour blood pressure has never been measured in Greenlanders. Purpose: to compare 24-hour blood pressure between Greenlanders and Danes, and to analyse the influence of Arctic food and life style on blood pressure. Methods: 186 healthy subjects were recruited for the study. 145 Greenlandic participants were categorized in three groups according to degree of Westernization based on dietary habits and current place of residence. 41 Danes were included as controls. All subjects underwent physical examination, laboratory screening of blood, and urine samples, and sociocultural information was obtained by interview. 24-hour blood pressure was measured. Results: 24-hour diastolic blood pressure was lower in Greenlanders than in Danes regarding the whole 24-hour period and both during day and night time, whereas systolic blood pressure was the same (Mean 24-hour blood pressure with 95% CI: Danes 123/75 mmHg (120/73–127/77), Greenlanders 122/69 (119/68–124/70)). Among Greenlanders, blood pressure increased with age and male gender, and systolic blood pressure increased with BMI. Blood pressure did not change with westernization. The difference between the two populations persisted after control for age, gender, BMI, out door temperature, and life style factors. Conclusions: Greenlanders have lower 24-hour diastolic blood pressure than Danes, and it is suggested that genetic factors are mainly responsible for the lower blood pressure level among Greenlanders. |
