RESUMO
BACKGROUND: The FRAX tool allows calculate the 10 year probability of fracture risk in men and women. OBJECTIVE: To compare the 10 years fracture risk calculated with the FRAX tool using or not bone densitometry. MATERIAL AND METHODS: A prospective, cross-sectional, open a comparative study was done with 40-80-year-old women, who were evaluated with bone densitometry. To calculate the fracture risk the FRAX tool was used with and without bone densitometry in each patient. Both results were compared with Mann-Whitney U test. RESULTS: The mean age was 54.2 ± 8.7 years. The median of the FRAX calculated risks without using bone densitometry was for major fracture 2.4 (1-12) and hip 0.3 (0-5.2). The calculated risks using bone densitometry was for major fracture 2.3 (1.2-11) and for hip 0.2 (0-3.6), without statistically significant differences among them. The calculated T score with FRAX was -1.0 (-2.7 ± 1.9). CONCLUSIONS: The results obtained with the FRAX tool using or not bone densitometry were similar. These findings will allow using this instrument in a greater number of patients.

BACKGROUND: Menstrual cycle characteristics have been studied throughout the world in several populations. OBJECTIVE: To analyze the frequency of occurrence of menstruation, duration and volume loss during it and its relationship with age, weight and body fat distribution in Mexican women. MATERIAL AND METHODS: prospective, cross-sectional and descriptive study conduced in women which accompanied patients to hospital consultation, with menstrual cycles considered normal by them, age was documented; body mass index (BMI) and waist hip ratio (WHR) were calculated. They were questioned about: periodicity of the cycle, duration, number and type of pads used per day, and the quantity of menstrual bleeding was calculated. STATISTICAL ANALYSIS: Central tendency and dispersion measurements, as well as percentages were calculated. For the comparison between the groups ANOVA was used and Pearson correlation analysis was done. RESULTS: 161 women were studied. Average age was 23.9 +/- 6.1 years, BMI 26.1 +/- 4.3 and WHR 0.9 +/- 0.1. The cycle periodicity was 29.3 +/- 3.1 days, being 86.4% between 28 and 30 days. The periodicity of menstrual bleeding was affected neither by age nor by BMI and WHR. Bleeding duration was 4.9 +/- 1.6 days, and the most common was from 4-7 days, only in those older than 35 years was from 1-3 days. The calculated average volume was 151.5 +/- 81.0 mL. In those with BMI < 20 loses were between 81and 120 ml, and in those with BMI > 35 from 121-160 ml; 85.5% of women with WHR < or = 0.85 had loses between 81 and 160 ml and 39.3% of those with WHR > 0.85. CONCLUSION: BMI greater than 35 is associated with more abundant bleeding, and android distribution of body fat with smaller bleeding.
