INTRODUCTION: Falls are one of the most devastating health problems of elderly people. The identification of causes of falls helps to establish proper prevention strategies. MATERIAL AND METHOD: The study was based on a group of community-dwelling, independent women aged over 50 years. The frequency of falls was calculated on the basis of a retrospective analysis of 1326 cases. 100 women were chosen for a telephone questionnaire to identify causes and consequences of falls. The average age was 63.9 (SD 8.6) and the average BMI was 27.6 (SD 5.4). RESULTS: Approximately 31% of 1326 women reported at least one fall a year. In the year preceding the questionnaire 62% of the participants reported one fall, 26%--two falls, 8%--three falls and 5%--four and more falls. In the surveyed group of 100 women 72% of falls occurred outdoors, which is 2.5 times more often than at home (28%). 68% of falls occurred between 12 pm and 6 pm. Summer is the season of the highest occurrence of falls (37%). In winter, the frequency of outdoor falls increases, whereas during summer the frequency of falls happening in and outdoors does not differ. The most frequent cause of falls, both in and outdoors, was slipping. Other important risk factors include: hypnotic drugs, walking impairments, balance deficit, vertigo, analgesics. Most of the falls had various intrinsic and extrinsic causes. KEY POINTS: We found that 30% of women aged over 50 years falls at least once a year. Both at home and outside falls resulted from slipping. For almost 80% of falls as a consequence of an injury. The majority of falls had intrinsic and extrinsic origins.

Causes of falls in women in Krakow population.

INTRODUCTION: Falls rank among the most serious medical problems in elderly persons, having psychological as well as social consequences. With several hundred fall risk factors known at present, it is necessary to select those that occur most frequently in a particular population. Only then will it be possible to implement effective fall prevention programmes with the aim of increasing awareness of the causes and consequences of falls in elderly persons. The aim of the study was to identify the profile of circumstances of falls in the population of women from Krakow above 50 years of age. MATERIAL AND METHODS: This paper presents the results of a pilot study carried out as a telephone survey. RESULTS: The study population of 50 women experienced 77 falls. The results served to estimate that over half of the women fell once in a year, with most falls occurring in summer as well as during the day. Among the environmental causes of falls outdoors, over 70% were attributable to slippery ground and uneven surface. 56% of the women were taking antihypertensive and cardiovascular drugs and 54% received at least two medications at the same time. Environmental causes were more important than health-related causes of falls. CONCLUSIONS: 1. A fall is most frequently the result of several causes. 2. While the study data need to be verified against a bigger study population, they are an important source and basis for further studies.

Fracture risk prediction in outpatients from Krakow Region using FRAX tool versus fracture risk in 11-year follow-up.

INTRODUCTION: FRAX is a an algorithm accepted by WHO for evaluating fragility fracture risk of women aged 40 years or more. The aim of this study was to use the FRAX tool to verify the risk of fractures in a population of women from the Cracow region in an 11-year follow-up. MATERIALS AND METHODS: The study was a retrospective cohort survey evaluating the incidence of fragility fractures over 11 years of follow-up. 5,092 women aged 50 years and more were randomly chosen from a group of 100,000 female patients of the Cracow Medical Centre who came to the Centre for densitometric examination between 1997 and 2001. Finally, 1024 patients were randomized into the study. After an average of 11 years a follow-up telephone survey was conducted among a randomly selected group of patients using a questionnaire corresponding to the one applied in the first survey. 10-year fracture risk was calculated for each patient using FRAX based on the BMI (Body Mass Index) and for 886 women using FRAX based on BMD (Bone Mineral Density) at the femoral neck. The Polish version of FRAX was validated by comparing the predicted risk with the actual incidence of fractures during the 11-year follow-up. RESULTS: The 10-year probability of a major osteoporotic fracture calculated using FRAX based on BMI for the entire group was 5.3% (median, 1st/3rd quartile: 3.5-8.5%) and the probability of a proximal femur (hip) fracture was 1.3% (median, 1st-3rd quartile: 0.7% -2.4%). In 886 women whose BMD T-score at the femoral neck was available, the mean probability of a major osteoporotic fracture was 4.9% (3.3-7.9%) and of a hip fracture 0.9% (0.3-2.3%). The actual absolute fracture risk calculated on the basis of the number of patients who had experienced a fracture during the follow-up was surprisingly much higher than the predicted figure. The risk of a major fracture in the study group was 17.7% and of a proximal femur fracture, 3%. CONCLUSION: In our opinion, FRAX is a very good screening tool, but not a precise diagnostic tool.
