В исследование был включен 1101 пациент в возрасте 90 лет и старше (медиана — 92 года), обратившийся за медицинской помощью. Противопоказания к анальгетикам извлекали из актуальных соответствующих инструкций по медицинскому применению. ХБС отмечался у 51% женщин и 52% мужчин. Среди участников исследования было выявлено 1225 противопоказаний, что в среднем составило 2,18±0,056 противопоказания на пациента. Количество противопоказаний было достоверно больше у мужчин (2,51±0,056), чем у женщин (2,05±0,063, р &lt; 0,001). Также у мужчин чаще встречались противопоказания к обеим группам анальгетиков, чем у женщин (22,3% против 12,5%, р &lt; 0,01). Наиболее частыми противопоказаниями являлись сердечно-сосудистые заболевания (75% пациентов). В целом, распространенность противопоказаний к НПВС среди долгожителей с ХБС была очень высокой, составляя 91-93%. В отличие от НПВС, противопоказания к опиоидным анальгетикам встречались в 5-6 раз реже (14-24% пациентов, р &lt; 0,001). Распространенность ХБС у долгожителей составляет 52%. Высокая распространенность противопоказаний к НПВС позволяет применять эту группу препаратов лишь у 10% пациентов. Противопоказания к опиоидным анальгетикам встречаются существенно реже. До 22,3% долгожителей с ХБС, имеющим противопоказания к применению анальгетиков обеих изучаемых групп, требуется использование альтернативных методов лечения боли.</p></abstract><trans-abstract xml:lang="en"><p>To assess the chronic pain (CP) prevalence among the long-livers, as well as both prevalence and spectrum of contraindications to non-steroidal anti-inflammatory drugs (NSAIDs) and opioids for systemic non-invasive use. The study included 1101 patients aged 90+ years old (median — 92 years) who applied for medical aid. Contraindications to analgesics were identified according to the effective versions of product labellings. CP was diagnosed in 51% of women and 52% of men. In the study population we found 1225 contraindications (mean: 2.18±0.056 per patient). The number of contraindications was significantly higher in men (2.51±0.056) compared to women (2.05±0.063, р&lt;0.001). The contraindications to both analgesic classes were also more common in men compared to women (22.3% versus 12.5%, р&lt;0.01). The most commonly seen contraindications corresponded to cardiovascular pathology (75% of patients). The general prevalence of contraindications to NSAIDs among the long-livers with CP was rather high (91-93%). On the contrary, the contraindications to opioids were 5-6 times less common (14-24% of patients, р&lt;0.001). The prevalence of CP among the long-livers is 52%. The high prevalence of the contraindications to NSAIDs allows to use these drugs only in approximately 10% of patients. The contraindications to opioids were significantly less commonly seen. Up to 22.3% of long-livers with CP have contraindications to both NSAIDs and opioids and need alternative approaches to pain-relieving therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический болевой синдром</kwd><kwd>нестероидные противовоспалительные средства</kwd><kwd>НПВС</kwd><kwd>опиоидные анальгетики</kwd><kwd>системное применение</kwd><kwd>сердечно-сосудистые заболевания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic pain</kwd><kwd>non-steroidal anti-inflammatory drugs</kwd><kwd>NSAIDs</kwd><kwd>opioids</kwd><kwd>systemic use</kwd><kwd>cardiovascular diseases</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">World Population Prospects: The 2017 Revision. 21 June 2017 [Электронный ресурс].
