Abstract
The aim of the study was to investigate age-related changes in bone mineralization indicators in the lumbar vertebrae in women with normal body weight living in the conditions of the Northern region.Material and methods. A complex somatometric examination and quantitative assessment of the bone tissue mineral density in the lumbar vertebrae were performed according to dual-energy X-ray absorptiometry of a group of Slavic women (n=127) with a normal body weight (BMI values from 18.5 to 24.9 kg/m2) aged 20 to 87 years, permanently residing in the Republic of Karelia. Statistical processing of the material was performed using the program "STATISTICA 6.0".Results. The BMI values in women increased significantly every decade of life. Direct correlations of mineral bone density (MBD) with the body length (r=0.46, p<0.001), with the body surface area (r=0.46, p<0.001), with absolute muscle mass (MM) (r=0.39, p<0.001), and with body mass (r=0.29, p<0.001) were revealed. No significant correlation with the adipose mass was found. The incidence of low MBD of the lumbar vertebrae was 48%: osteopenia was in 29%, osteoporosis was in 19% of women. The analysis of the component composition of the body in women with different levels of bone mass showed significant differences in the absolute content of muscle mass.Conclusion. In women with a normal BMI, body weight and muscle mass play an essential role in maintaining lumbar vertebrae bone mineral density.

Summary
Цель исследования – изучение возрастных изменений показателей минерализации костной ткани в поясничных позвонках у женщин с нормальной массой тела, проживающих в условиях Северного региона. Проводились комплексное соматометрическое обследование и количественная оценка минеральной плотности ткани в поясничных позвонках по данным двухэнергетической рентгеновской абсорбциометрии группы женщин славянского этноса (n=127) с нормальной массой тела (значениями ИМТ от 18.5 до 24.9 кг/м2) в возрасте от 20 до 87 лет, постоянно проживающих в условиях Республики Карелия. Выявлены прямые корреляционные связи минеральной плотности костной ткани (МПК) с длиной тела (r=0.46, p
