Falls and hip fracture. A reasonable basis for possibilities for prevention? Some preliminary data from the MEDOS study Mediterranean Osteoporosis Study.
The Mediterranean Osteoporosis Study (MEDOS), a multicentre study on incidence, risk factors, and means of prevention of hip fracture in the Mediterranean region, started in 1986 and involved 14 centres, in Portugal, Spain, France, Italy, Greece, and Turkey. The design includes a case-control study comparing 8,185 individuals in age groups above 50 (2,816 cases and 5,369 controls; two controls per case). Information on falls was only collected for a small fraction of the controls. In a questionnaire including 160 main questions eleven referred to circumstances around the fall. Falls were classified according to a) high risk environment, e.g. occurred in darkness and b) high risk fallers, e.g. confusion, reduced functional ability. There was great variation between centra for a majority of the results. However, 2/3 of fractures happened during daylight. 9% of fractures, same for both males and females, took place in darkness. Females have more indoor fractures than males. Around 15% of fractures took place in connection with going to the toilet. Mental factors play a minor role as reported immediate cause to the fall. Before the fall that caused the hip fracture between 28-84% could get up from a chair without any difficulties. Of the males 0-26% lived alone as against 0-37% or females.


CONCLUSIONS
The data on circumstances around the fall shows a complex pattern with substantial variation between different cultures, but where a, however, minority took place under risk circumstances that have a clear preventive potential.
