Изучить взаимосвязи между уровнем витамина D и наличием и степенью выраженности депрессии у лиц в возрасте ≥ 90 лет, проживающих в стационарных учреждениях социального обеспечения (СУСО).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В одномоментное поперечное исследование были включены 351 человек (25% мужчин) в возрасте 90–104 (медиана 92) года, постоянно проживающие в СУСО г. Москвы. Для выявления депрессии использовали гериатрическую шкалу депрессии (Geriatric Depression Scale, GDS-15); вероятную депрессию диагностировали при сумме баллов ≥ 5. Уровень витамина D (25-гидроксикальциферола) определяли в сыворотке крови методом хемилюминесцентного анализа на микрочастицах; норма 30–100 нг/мл.</p></sec><sec><title>Результаты</title><p>Результаты. Депрессия диагностирована у 67,2% долгожителей. Уровень витамина D варьировал от 3 до 36 нг/мл</p><p>(медиана 6; интерквартильный размах 5–8) и соответствовал норме менее чем у 1% долгожителей, при этом у 83% имел место выраженный дефицит. У долгожителей с депрессией уровень витамина D был значимо меньше, чем у долгожителей без депрессии (абсолютная разница медиан 2 нг/мл; р &lt; 0,001). Однофакторный регрессионный анализ показал, что у институализированных долгожителей витамин D обладает протективным эффектом в отношении депрессии: при увеличении уровня витамина D на каждый 1 нг/мл шансы иметь депрессию снижаются на 14% (ОШ 0,86; 95% ДИ 0,81–0,92; р &lt; 0,001). При внесении в регрессионную модель поправок на возраст, пол, наличие детей, уровень образования и физической активности ассоциация между витамином D и депрессией сохраняла свою значимость, при этом идентифицировали 2 независимых предиктора депрессии с протективным эффектом: витамин D (ОШ 0,86; 95% ДИ 0,80–0,93; р &lt; 0,001) и высокий уровень физической активности (ОШ 0,47; 95% ДИ 0,27–0,81; р = 0,007). ROC-анализ подтвердил наличие взаимосвязи между витамином D и депрессией: уровень витамина D ≤ 12 нг/мл предсказывал наличие депрессии с чувствительностью 71%, специфичностью 70% и диагностической точностью 71%. Площадь под ROC-кривой, равная 0,666, указывает на удовлетворительное качество модели. Однофакторный регрессионный анализ показал, что при уровне витамина D ≤ 12 нг/мл шансы иметь депрессию выше в 5,6 раза (ОШ 5,60; 95% ДИ 2,47–12,70; р &lt; 0,001).</p></sec><sec><title>Заключение</title><p>Заключение.

To examine the relationship between vitamin D levels and the prevalence and severity of depression in people aged ≥90 living in the nursing homes.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A cross-sectional study was conducted on 351 people (25% men) aged 90-104, with a median age of 92, who were permanently residing in Moscow nursing homes. The Geriatric Depression Scale (GDS-15) was used to detect depression, with possible depression diagnosed at a score of 5. Vitamin D (25-hydroxycalciferol) levels were determined in blood serum using chemiluminescence analysis on microparticles, with normal levels ranging from 30 to 100 ng/ml.</p></sec><sec><title>Results</title><p>Results. Depression is diagnosed in 67,2% of the oldest old. Vitamin D levels range from 3 to 36 ng/ml (median 6, interquartile range 5-8), and less than 1% of those with the highest vitamin D levels have a vitamin D deficiency. The absolute median difference in vitamin D between the oldest with and without depression is 2 ng/ml (p&lt;0.001). A single-factor regression analysis shows that vitamin D in the institutionalized oldest old has a protective effect on depression: increasing vitamin D levels per 1 ng/ml reduces the chance of depression by 14% (OR 0,86; 95% CI 0,81-0,92; p&lt;0,001). After adjusting for age, sex, children, education, and physical activity in the regression model, the association between vitamin D and depression remains significant for both vitamin D and high levels of physical activity as predictors of depression with protective effect: vitamin D (OR 0,86; 95% CI 0,80-0,93; p&lt;0,001); high level of physical activity (OR 0,47; 95% CI 0,27-0,81; p=0,007). ROC analysis confirms a correlation between vitamin D and depression. Vitamin D levels ≤12 ng/ml predict depression levels with 71% sensitivity, 70% specificity, and 71% diagnostic accuracy. The ROC-curve area below 0.666 indicates a satisfactory model quality. The single-factor regression analysis shows that the chances of depression are 5,6 times higher at vitamin D levels of ≤12 ng/ml (OR 5,60; 95% CI 2,47-12,70; p&lt;0,001).</p></sec><sec><title>Conclusion</title><p>Conclusion. Associations between vitamin D and the presence and severity of depression among the oldest old living in the nursing homes in Moscow have been identified.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>долгожители</kwd><kwd>девяностолетние</kwd><kwd>депрессия</kwd><kwd>институализация</kwd><kwd>дома престарелых</kwd><kwd>витамин D</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oldest old</kwd><kwd>nonagenarians</kwd><kwd>depression</kwd><kwd>institutionalization</kwd><kwd>nursing homes</kwd><kwd>vitamin D</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Berger AK, Small BJ, Forsell Y, et al.
