Lack of adherence to recommended therapy will reduce its effectiveness and can subsequently lead to disease progression, disabilities or even death. A vast number of research studies have emphasized the magnitude of medication nonadherence and its effect on treatment outcomes, patient’s health, healthcare providers and the associated costs; medication nonadherence remains a major concern that is believed to be widely practiced amongst medication taking patients. The current systemic review aims to cohere the available evidence regarding medication nonadherence rate, practices, and potential affecting factors and predictors. A search through different databases was conducted, including PubMed, Medline, and CINHAL for recently published research articles, within five years. The terms used for the search include medication nonadherence, medication nonadherence, factors affecting medication nonadherence and predictors of medication nonadherence. The search was limited to human subjects, English language journal articles and exclusion of review articles, case studies, and data from clinical trials as patient adherence is closely observed. The search resulted in 667 articles and only 65 articles were included and further screened. However, according to our exclusion criteria, 15 articles only were included in this review. The three most reported practices of medication nonadherence are prescription abandonment, nonconforming, and non-persistence. There are five reported factors that may lead to nonadherence practices such as socioeconomic-related factors, healthcare system-related factors, patient-related factors, disease-related factors, and therapy-related factors. In conclusion, medication nonadherence practice is a multi-dimensional phenomenon that requires a multi-targeted solution.

Background/Aims: There has been a paucity of published data on the epidemiology of inflammatory bowel disease (IBD) in Central Asia and Kazakhstan. Therefore, we aimed to study IBD prevalence and patient awareness among adults in Kazakhstan. Methods: The cross-sectional study was carried out among subjects of both sexes aged 18 years and older using IBD Alert Questionnaire (CalproQuest), single fecal calprotectin test, and endoscopy with biopsy to verify IBD from January to December 2017, across regions of Kazakhstan. All participants were included in the study after providing informed consent.Results: Out of 115,556 subjects, there were 128 confirmed IBD cases, in which 36 Crohn’s disease (CD) and 92 ulcerative colitis (UC) cases identified. The age and sex-adjusted IBD prevalence were 113.9 (95% confidence interval [CI], 69.0–158.9) per 100,000 population. The age- and sex-adjusted prevalence for UC were 84.4 (95% CI, 44.8–123.9) and for CD were 29.5 (95% CI, 8.2–50.9) per 100,000 population.Conclusions: This is the first report on the prevalence of IBD with a verified diagnosis in the Central Asia and could be used to better plan and allocate healthcare resources for IBD management program.

The data on seroprevalence of anti-SARS-CoV-2 antibodies in Kazakhstani population are non-existent, but are needed for planning of public health interventions targeted to COVID-19 containment. The aim of the study was to estimate the seropositivity of SARS-CoV-2 infection in the Kazakhstani population from 2020 to 2021. We relied on the data obtained from the results from “IN VITRO” laboratories of enzyme-linked immunosorbent assays for class G immunoglobulins (IgG) and class M (IgM) to SARS-CoV-2. The association of COVID-19 seropositivity was assessed in relation to age, gender, and region of residence. Additionally, we related the monitoring of longitudinal seropositivity with COVID-19 statistics obtained from Our World in Data. The total numbers of tests were 68,732 for SARS-CoV-2 IgM and 85,346 for IgG, of which 22% and 63% were positive, respectively. The highest rates of positive anti-SARS-CoV-2 IgM results were seen during July/August 2020. The rate of IgM seropositivity was the lowest on 25 October 2020 (2%). The lowest daily rate of anti-SARS-CoV-2 IgG was 17% (13 December 2020), while the peak of IgG seropositivity was seen on 6 June 2021 (84%). A longitudinal serological study should be envisaged to facilitate understanding of the dynamics of the epidemiological situation and to forecast future scenarios.

Cardiovascular disease encompasses different diseases affecting the heart or circulatory vessels and is the leading cause of morbidity and mortality worldwide. However, there is a lack of data on the prevalence and magnitude of the disease among the young population in Kazakhstan. The current study is a systematic review of the literature that aims to analyze published data to estimate the prevalence and risk factors of cardiovascular diseases among young people in Kazakhstan. The search for references performed using different databases including PubMed, MEDLINE and Embase. A total of 107 papers were retrieved, of which only 8 met the inclusion criteria and included in the study. There is a lack of literature that describes the prevalence of cardiovascular diseases among young people in Kazakhstan; however, the estimated average in this study, based on the weighted pool of general population is 22.4%. Interestingly, the most commonly reported modifiable risk factors among young adults include unhealthy diet, smoking, mental health, physical inactivity, drug use and metabolic disorders. While there is a general improvement in cardiovascular health among older people, young adults appear to indulge themselves in several modifiable risk factors and develop unhealthy cardiovascular status.

Background: In 2023, tuberculosis (TB) caused 1.25 million deaths globally, remaining a leading infectious killer. Central Asia and Southern Caucasus face high TB burdens, particularly Mongolia. This review synthesizes TB prevalence data and diagnostic capabilities in these regions to support public health strategies. Methods: This systematic review aimed to synthesize current data on TB prevalence in Central Asia, Southern Caucasus, and Mongolia to support public health strategies and research priorities. A comprehensive search of PubMed and Google Scholar was conducted for English-language articles published up to 2023. Studies were assessed using a modified Newcastle–Ottawa Scale. Nine studies met the inclusion criteria, covering Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, Turkmenistan, Mongolia, Georgia, Armenia, and Azerbaijan. Results: TB incidence ranged from 67 per 100,000 in Kazakhstan to 190 per 100,000 in Kyrgyzstan, with the highest prevalence of 68.5% in Mongolia. TB affected men more frequently (65.3%), and the key risk factors included HIV (30.5%), comorbidities, and undernutrition. Diagnostic performance varied significantly (microscopy sensitivity, 45–65%; GeneXpert MTB/RIF, 89–96% sensitivity and 98% specificity for rifampicin resistance). Diagnostic turnaround times ranged from hours (molecular) to weeks (conventional). Only 58% of TB facilities had GeneXpert technology, with urban–rural disparities in diagnostic access. Drug-resistant TB imposed a significant economic burden, with treatment costs ranging from USD 106 to USD 3125. Conclusions: Strengthening surveillance, improving data collection, and conducting longitudinal studies are essential for designing effective TB control strategies in these regions. Significant diagnostic gaps persist across these regions, especially with regard to drug-resistant strains. Point-of-care molecular diagnostics, improved algorithms, and expanded laboratory training show promise. Future research should focus on rapid biomarker-based diagnostics, field-deployable technologies for settings with limited resources, and AI integration to enhance diagnostic accuracy and efficiency.

Knee osteoarthritis (KOA) is a degenerative joint disease that leads to pain, stiffness, and disability. While established risk factors such as age, obesity, and joint injury are well-documented, the role of cultural practices remains underexplored. This study investigates the association between traditional cultural practices and KOA prevalence in Central Asia. A case-control study was conducted between January and March 2025 in Turkestan, Kazakhstan, involving 337 KOA cases and 685 matched controls. Participants completed structured questionnaires assessing demographic characteristics, lifestyle habits, and cultural practices. Unconditional logistic regression analyses identified associations between cultural factors and KOA, adjusting for age, sex, BMI, education level, physical workload, and type of residence. Frequent floor sitting (OR = 4.25, 95% CI: 3.02-5.99), squat toilet use (OR = 2.32, 95% CI: 1.66-3.23), and rural residence (OR = 7.57, 95% CI: 4.99-11.48) were strongly associated with KOA. Daily prayer postures did not significantly differ between cases and controls. Traditional cultural practices involving prolonged knee flexion were associated with KOA. Public health initiatives should consider culturally appropriate strategies that may help mitigate knee strain. Further longitudinal research is needed to establish causality.
