We investigated factors associated with falls in a community-based prospective study of 761 subjects 70 years and older. The group experienced 507 falls during the year of monitoring. On entry to the study a number of variables had been assessed in each subject. Variables associated with an increased risk of falling differed in men and women. In men, decreased levels of physical activity, stroke, arthritis of the knees, impairment of gait, and increased body sway were associated with an increased risk of falls. In women, the total number of drugs, psychotropic drugs and drugs liable to cause postural hypotension, standing systolic blood pressure of less than 110 mmHg, and evidence of muscle weakness were also associated with an increased risk of falling. Most falls in elderly people are associated with multiple risk factors, many of which are potentially remediable. The possible implications of this in diagnosis and prevention are discussed.

Means and standard deviations are reported for the State-Trait Anxiety Inventory and the Zung Self-Rating Depression scale, collected during the course of a general health survey. Data for different age samples and for both sexes are presented for use in the evaluation of the significance of anxiety and depression levels in patients presenting with these symptoms. High estimates of reliability based on internal consistency statistics were found for all scales. Females scored more highly on both the measures and scores were inversely correlated with age, indicating the importance of specific and appropriate norms in assessing affective states.

A sample of 761 subjects 70 years and over was drawn from general-practice records of a rural township. Each subject was assessed and followed for 1 year to determine the incidence of and factors related to falls. The fall rate (number of falls per 100 person-years) increased from 47 for those aged 70-74 years to 121 for those 80 years and over. There was no sex difference in fall rate but men were more likely than women to fall outside and at greater levels of activity. Twenty per cent of falls were associated with trips and slips but we found no evidence that inspection of homes and installation of safety features would have decreased the fall rate. Ten per cent of falls resulted in significant injury. Men who fell had an increased subsequent risk of death compared with those who did not fall (relative risk 3.2, 95% CI 1.7-6.0). Subsequent mortality was increased among women who fell but not to significant levels (relative risk 1.6, 95% CI 0.9-2.7).

Continuous treatment of postmenopausal osteoporosis with calcitriol for three years is safe and significantly reduces the rate of new vertebral fractures in women with this disorder.
