Introduction: the adequate intake of nutrients involved in bone metabolism can prevent and even reduce the risk of osteoporosis. Objective: verify the intake of total calories, protein and calcium in women diagnosed with osteopenia and osteoporosis after menopause. Method: a study of 25 women diagnosed with osteopenia (n=17) or osteoporosis (n=8) in the postmenopausal period, who were members of the Prática de Exercícios Físicos na Osteoporose (Practice of Physical Exercise Against Osteoporosis) (PEFO) study group of the Universidade Tecnológica Federal do Paraná (the Federal Technology University of Paraná) (UTFPR). The study was divided into two data collection phases: assessment of body composition and bone mineral density by Dual-energy X-ray Absorptiometry (DXA) and the recording of food consumption over the previous 72 hours by means of a structured interview. Results: there was a difference between the reference values and the average values found for caloric, protein and calcium intake. There were higher values for protein, while calcium intake was low. The osteoporosis group (mean 59.24+80.07, p<0.05) ingested significantly more protein than the osteopenia group (mean 15.14+16.53, p<0.05). The results showed a significant negative correlation between protein intake and hip BMD (r=-0.416, p<0.05). Conclusion: adequate intake of protein should be recognized as a protective factor for osteoporosis and considered by nutritionists, as well as being widely featured in public health campaigns.

Introduction: The measurement of body fat is a way to obtain information about the characteristics that can lead to a framework of certain diseases. Thus, women in postmenopausal period experience significant variations in the body composition and fat distribution. Objective: To develop an equation to estimation of the body fat percentage in women with osteopenia / osteoporosis based on anthropometric measurements easily obtainable. Methods: The sample consisted of 74 women participating in the study group of the Physical Exercise Program for Osteoporosis Federal Technological University of Paraná, all in postmenopausal period and with osteopenia or osteoporosis. It evaluated body composition and bone mineral density by absorptiometry Radiological Dual Energy (DXA), anthropometry and body circumferences (waist, abdomen and hips), and nutritional status by the Body Mass Index (BMI) as the World Health Organization classification. Results: The sample can be characterized by the following average data: age of 59.32 ± 6.96, 27.14 ± 3 BMI 90, Waist Hip Ratio of 0.85 ± 0.08 and Body fat percentage 40.35 ± 4.04. The proposed equation was Body Fat Percentage (BFP) = 14,419 + (0.405 x BMI) + (0.147 x HC) using only two predictor variables, BMI and hip circumference (PQ). Conclusion: The standard error of estimate of the proposed equation was 2.89 (R2 = 0.501) can be considered low average values for the percentage of fat in this population, suggesting that the equation can be used to estimate the percentage of body fat in postmenopausal women.
