Аскаридоз является одним из наиболее распространённых паразитарных заболеваний, которым ежегодно заражается около 1,5 миллиона человек в мире. В России ежегодно регистрируется от 40 до 60 тысяч заболевших. В целях принятия эффективных управленческих решений по проведению санитарно-эпидемиологических и профилактических мероприятий был осуществлён поиск факторов окружающей среды, потенциально влияющих на эпидемический процесс по аскаридозу во Владимирской области.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ходе исследования проведён анализ архивных статистических данных о заболеваемости населения аскаридозом, состоянии окружающей среды (загрязнение атмосферного воздуха, воды и почвы), социально-экономической обстановке (уровень безработицы, величина средней заработной платы, количество врачей и среднего медицинского персонала, обеспеченность жильём), а также о климатических показателях (среднемесячная температура, количество дней в месяце с осадками, влажность воздуха и величина снежного покрова) в регионе. Статистическую обработку данных, корреляционно-регрессионный анализ проводили с помощью программы Statistica. Построение и редактирование карт проводилось с использованием ГИС программы ArcView 3.1 и стандартной компьютерной программы Paint.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что заболеваемость аскаридозом в области характеризуется существенной дифференциацией. Получены статистически достоверные корреляционные связи заболеваемости с показателями окружающей среды, методом линейной регрессии построено математическое уравнение для прогнозирования уровня заболеваемости в регионе.</p></sec><sec><title>Заключение</title><p>Заключение. Проведённое исследование показало, что в эпидемиологии аскаридоза во Владимирской области ведущую роль сохраняют за собой климатические параметры окружающей среды, определяющие возможность развития яиц аскарид в окружающей среде до инвазионной стадии. Региональным фактором, оказывающим влияние на эпидемический процесс (опосредованно через угнетение защитных функций детского организма и сокращения сроков развития яиц аскарид), является загрязнение атмосферного воздуха стационарными объектами. Полученные данные можно использовать для оценки риска заражения аскаридозом с целью обеспечения биологической безопасности в регионе.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Ascariasis is one of the most common parasitic diseases that infect about 1.5 million people in the world every year. In Russia, from 40 to 60 thousand cases are registered annually. To make effective management decisions on sanitary-epidemiological and preventive measures, the search for environmental factors that potentially affect the epidemic process of ascariasis in the Vladimir region was carried out.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study analyzed archived statistical data on the incidence of ascariasis in the population, the state of the environment (air, water, and soil pollution), the socio-economic situation (unemployment rate, average salary, number of doctors and nurses, housing provision), as well as climate indices (average monthly temperature, number of days in a month with precipitation, humidity and snow cover) in the region. Statistical data processing and correlation and regression analysis were performed using the Statistica software. The maps were built and edited using the ArcView 3.1 GIS program and the standard Paint computer program.</p></sec><sec><title>Results</title><p>Results. The incidence of ascariasis in the region is characterized by significant diversity. Statistically reliable correlations of morbidity with environmental indices were obtained, and a mathematical equation was constructed using linear regression to predict the level of morbidity in the region.</p></sec><sec><title>Conclusion</title><p>Conclusion. In the epidemiology of ascariasis in the Vladimir region, a leading role retains climatic, environmental indices determining the possibility of developing eggs of ascarids in the environment to the infective stage. A regional factor that affects the epidemiological process (indirectly through the suppression of the protective functions of the child’s body and reducing the development time of Ascaris eggs) is air pollution by stationary objects. The data obtained can assess the risk of infection with ascariasis to ensure biological safety in the region.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аскаридоз</kwd><kwd>окружающая среда</kwd><kwd>загрязнение воздуха</kwd><kwd>климатические параметры</kwd><kwd>математическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ascariasis</kwd><kwd>environment</kwd><kwd>air pollution</kwd><kwd>climate parameters</kwd><kwd>mathematical model</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">Шахриев А.Р., Османов Р.О., Османов О.Р., Рамазанова Б.М., Мусаева З.Т.
