In Norsjö in Northern Sweden a cardiovascular intervention programme, for adults is presently tested. The aim of the present study was to investigate the presence of factors related to cardiovascular disease in all 15-year-old adolescents living in Norsjö in 1987 and 1988. The total cholesterol concentration in serum, as an average for the test period, was 4.2 mmol/l and 4.7 mmol/l for boys and girls, respectively. Fourteen per cent of the boys and 32% of the girls had a total cholesterol concentration exceeding 5 mmol/l. Twenty-seven per cent of the adolescents had high values for two or more variables related to risk of developing cardiovascular disease. The evaluation of the dietary registrations showed unsatisfactory values for fibre, P/S ratio and total fat. The dietary habits were better in the 15-year-olds in 1988 than in 1987 as judged by significantly higher average daily intake of fibre as well as a higher content of fibre per megajoule in the food.

Salivary flow rate and salivary glucose concentration in patients with diabetes mellitus influence of severity of diabetes.

Eleven diabetics (eight with type I diabetes) aged 20 to 45 years underwent salivary investigations on two occasions, one to five months apart, during different metabolic control. Stimulated salivary flow rate showed a great inter-individual variation, and was not changed by improved metabolic control. Salivary glucose concentration was lower during the period of better metabolic control. In stimulated parotid saliva a positive correlation between glucose levels in saliva and blood was seen. A blood glucose threshold for glucose excretion at about 10-15 mmol/L might be present. There were no significant differences in pH, buffering capacity, total amount of protein, amylase, lysozyme, peroxidase or electrolytes (Na+, K+, Ca2+, PO42- and Mg2+) in the saliva between the two occasions of different metabolic control. In conclusion, the degree of diabetic metabolic control does not seem to be of major importance for salivary flow rate or composition in diabetics except for the salivary glucose concentration.
