- To examine associations between calcium intake in the diet, lifestyle factors, and forearm bone mineral density (BMD) in order to identify population subgroups for targeting by screening programs. A questionnaire was sent to a random sample of 15 of the inhabitants aged 20-79 years from 2 Swedish municipalities, and the subsample from one of the municipalities was invited to measurement of BMD. The survey response rate was 74 (n=1,1121,510) and participation in BMD measurements was 68 (n=448659). Only a tendency (p=.085) toward direct association between calcium intake and forearm BMD was found, and the best multiple regression model was retained to explain BMD excluded calcium intake. Low calcium intake was, instead, in complementary analyses, found to be correlated with the factors old age, female sex, and urban residence in the best multiple regression model. Population subgroups whose calcium intake is in a range that justifies preventive action could be identified. Screening programs staffed by public health nurses can thereby be informed regarding the subgroups of the population that are at the highest risk of insufficient calcium intake. © 2007, Blackwell Publishing, Inc.

- All persons aged 70 through 75 years (N = 457) in a Swedish community were invited to participate in a 9 week balance training study. Out of 55 interested subjects, 15 were chosen at random for a study group; 15 matched controls were also selected. Before and after the investigation period the balance function was assessed by clinical balance tests and dynamic posturography. In the clinical balance tests, the training group significantly improved their balance standing on one leg with eyes closed as well as standing on one leg while shaking the head; they also walked 15 m back and forth faster. In the dynamic posturography the training group significantly improved their equilibrium scores in the 3 most difficult test conditions. The results of the control group were unchanged except for one test condition in the dynamic posturography. The differences in one-leg standing with head shaking, walking 2 x 15 m, and the equilibrium score using sway-referenced platform in dynamic posturography were proved to be attributable to the training. The first investigation in all 29 subjects formed normative dynamic posturography data for the age group 70 through 75 years. The normative posturographic data of this age group differed from previously obtained data in the age groups 20 through 59 and 60 through 69 years. It is concluded that elderly may improve their balance by regular balance training exercises for as short a period as 9 weeks. This might prove to be of great value in improving balance and thereby preventing accidental falls and subsequent fractures in elderly.
