Выявление факторов риска снижения когнитивных функций (КФ) при старении имеет большое значение для профилактики деменции. Брак или сожительство считают защитным фактором в отношении здоровья. При этом влияние семейного положения на возрастное снижение КФ изучено недостаточно.</p><p>Цель исследования – изучить связи показателей КФ с семейным статусом в одномоментном подходе и в двух серийных измерениях за 9 лет в российской популяционной выборке от среднего до старческого возраста.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование выполнено на материале случайной популяционной выборки жителей Новосибирска 45–69 лет, обследованной исходно в 2003–2005 гг. (n = 9360, проект HAPIEE). В анализ включена подвыборка лиц, имеющих двукратные серийные измерения, – 3153 чел. Средний период наблюдения – 9,2 (SD = 0,7) года. Тестирование КФ выполнено стандартными методами, включающими непосредственное и  отсроченное воспроизведение 10  слов, семантическую речевую активность, концентрацию внимания. Для оценки семейного статуса использовали стандартизованные опросники, выделяли группы одиноких и неодиноких участников.</p></sec><sec><title>Результаты</title><p>Результаты. В изученной популяционной выборке (n = 3153, 62% женщин) средний возраст участников в период исходного обследования составил 60,3 ± 6,8 года, в период повторного – 69,5 ± 6,9 года. За 9 лет наблюдения выявлена существенная отрицательная динамика исследованных когнитивных доменов (p &lt; 0,001) у лиц обоего пола, одиноких по семейному статусу. В мультивариантных моделях скорость регресса показателей КФ в год не отличалась в группах с разным семейным статусом у лиц обоего пола, кроме более быстрого снижения семантической речевой активности у женщин, частично за счет исходно высокого уровня. У неодиноких по семейному статусу женщин выявлен более высокий темп снижения этого показателя (р = 0,007) по сравнению с одинокими участницами исследования независимо от возраста и других факторов риска.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты, полученные в популяционной выборке Новосибирска, поддерживают потенциальное протективное влияние брака или сожительства на сохранение КФ при старении.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The identification of risk factors for cognitive decline during ageing is of great importance for prevention of dementia. Being married or cohabited is considered a protective factor for health. The impact of marital status on age-related decrease of cognitive functions (CF) is understudied.</p><p>The aim of the study was to investigate the relationship between the indicators of CF and marital status in a cross-sectional analysis and in 2 serial measurements over 9 years in a population sample of middle to older age in Russia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was based on a random population sample of men and women aged 45–69 years old examined at baseline in 2003–2005 in Novosibirsk (n = 9360, HAPIEE project). Present analysis included a subsample of persons with repeated serial measurements – 3153 people. The average follow-up period was 9.2 (SD = 0.7) years. CF was assessed using standard validated methods, including immediate and delayed recall of 10 words, semantic verbal fluency and letter cancellation test. Marital status was determined by standardized questionnaires, groups of single and married/cohabiting participants were identified.</p></sec><sec><title>Results</title><p>Results. In studied population sample (n = 3153, 62% of women), the mean age of participants at baseline examination was 60.3 ± 6.8 years old, and at follow-up examination – 69.5 ± 6.9 years old. During the 9-year follow-up, a significant negative dynamics of the studied cognitive domains (p &lt; 0.001) was revealed in single for both sexes. In multivariable-adjusted models, the rate of CF regress per year did not differ by marital status in both sexes, except for increased rate of decline in semantic verbal fluency in women, partly it was explained by high baseline level. Married or cohabiting women had faster rate of decline in this indicator (p = 0.007) compared with single, regardless of age and other risk factors.</p></sec><sec><title>Conclusion</title><p>Conclusion. The findings obtained in this population sample in Novosibirsk support a potential protective effect of marriage or cohabitation on CF preservation during ageing.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>когнитивные функции</kwd><kwd>семейный статус</kwd><kwd>популяция</kwd><kwd>старение</kwd><kwd>снижение когнитивных функций</kwd><kwd>когорта НAPIEE</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cognitive functions</kwd><kwd>family status</kwd><kwd>population</kwd><kwd>ageing</kwd><kwd>cognitive decline</kwd><kwd>HAPIEE cohort</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Проект HAPIEE поддержан грантами WT081081AIA и NIA (1R01AG23522-01); текущий этап поддержан грантом РНФ №20-15-00371.
