Для оценки факторов снижения МПК проводились исследования анамнеза жизни, образа жизни, питания, антропометрических данных, акушерско-гинекологического анамнеза, течения беременности. Всем родильницам определялись уровни 25-гидроксикальциферола (25-OH-D) сыворотки крови, паратиреиоидный гормон (ПТГ). Оценка МПК проводилась методом двухэнергетической рентгеновской остеоденситометрии в трех отделах скелета. За снижение МПК, соответствующее остеопении принимали Z-критерий от -1 до -2,5 SD, ниже -2,5 SD – соответствующее остеопорозу.</p></sec><sec><title>Результаты</title><p>Результаты: По результатам рентгеновской остеоденситометрии сформировано две группы: 1 (n=70) - родильницы с остеопенией, 2 (n=42) - родильницы с нормальной МПК. В первой группе остеопения в дистальном отделе предплечья встречалась у 48%, в поясничном отделе позвоночника - у 16%, в проксимальном отделе бедра - у 36% обследованных. Установлено влияние следующих возможных факторов в 1 группе пациенток: ИМТ в 15-20 лет ≤18 кг/м² (р&lt;0,013), ИМТ ≥ 25 кг/м² (р&lt;0,018), 25-OH-D менее 25 нг/мл (р&lt;0,0018), содержание кальция в рационе менее 800 мг/сут (р&lt;0,041). Обнаружено влияние нарушений менструального цикла (р&lt;0,052) и преэклапсии (р&lt;0,042) на МПК в поясничном отделе позвоночника и. Дефицит витамина D выявлен у 82% родильниц в 1 группе, у 18% - недостаточность; во 2 группе дефицит витамина D встречался у 16%, недостаточность - у 70%, у 14% - нормальные значения. У женщин с сочетанием таких факторов, как ИМТ≤18 кг/м; питание с содержанием кальция меньше 800 мг/сутки, нарушением менструального цикла в сочетании с недостаточностью витаминам D - остеопения в дистальном отделе предплечья встречалась в 11 раз чаще, чем у женщин из группы без вышеуказанных факторов (OR=11,47059; CI 95%=[4,0326; 32,627]).</p></sec><sec><title>Заключение</title><p>Заключение: Наиболее существенное влияние на развитие остеопении у родильниц оказывают следующие факторы: ИМТ ≤18 кг/м²; 25-ОН-D&lt;25 нг/мл; питание с содержанием кальция &lt;800 мг/сутки, преэклампсия. Совокупность этих факторов может повышать риск развития остеопении в дистальном отделе предплечья.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: Osteopenia is a common condition. Therefore, identification of groups for prevention of osteoporosis and restoration of bone mineral density (BMD) remains relevant.</p></sec><sec><title>Aim</title><p>Aim: to assess the factors contributing to development of osteopenia in puerperas.</p></sec><sec><title>Methods</title><p>Methods: prospective cross-sectional study. We examined 112 patients aged 20-35, 3-5 days after delivery. To assess possible factors for BMD decrease, we analyzed medical history, lifestyle, nutrition, anthropometric data, obstetric and gynecological history, and pregnancy course. We also assessed serum levels of 25-hydroxycalciferol (25-OH-D) and PTH. BMD was measured by dual energy x-ray osteodensitometry. We considered Z-score from -1 to -2.5SD as osteopenia, below -2.5 SD-as osteoporosis.</p></sec><sec><title>Results</title><p>Results: based on Z-score values, two groups were formed: 1 (n=70) - puerperas with osteopenia, 2 (n=42) - puerperas with normal BMD. In the first group, osteopenia in the distal radius was observed in 48%, in the lumbar spine in 16% and in the proximal femur in 36%. Influence of the following possible factors in group 1 was established: BMI in 15-20 years ≤ 18 kg/m2 (p&lt;0.013), BMI ≥ 25 kg/m2 (p&lt;0.018), 25-OH-D less than 25 ng / ml (p &lt; 0.0018), calcium intake less than 800 mg/day (p&lt;0.041). Menstrual disorders (p&lt;0.052) and preeclapsia (p &lt; 0.042) affected lumbar spine BMD. In group 1, vitamin D deficiency was detected in 82% of women, 18% showed vitamin D insufficiency; in group 2, vitamin D deficiency was found in 16%, deficiency in 70%, in 14% vitamin D was normal. In women with a combination of factors such as BMI≤ 18 kg/m; calcium intake lower than 800 mg/day, menstrual cycle disorders, vitamin D deficiency - osteopenia in the distal radius occured 11 times more often (OR=11,47059; CI 95%=[4,0326; 32,627]).</p></sec><sec><title>Conclusion</title><p>Conclusion: most significant impact on BMD decrease in puerperas can be expected if patient has the following risk factors: BMI≤18 kg/m2; 25-OH- D&lt;25 ng/ml ; nutrition with calcium intake &lt;800 mg per day, preeclampsia. Combination of these factors may increase the risk of osteopenia in the distal radius.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>минеральная плотность костной ткани</kwd><kwd>витамин D</kwd><kwd>факторы риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>bone mineral density</kwd><kwd>vitamin D</kwd><kwd>risk factors</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование проведено при поддержке ФГБУ НМИЦ им.
