RESUMEN

The COVID-19 pandemic is ongoing worldwide, and various case and death numbers are being reported to track its spread. However, the number of actual cases is uncertain due to under-reporting. Using mortality data as a more reliable indicator, this study in Kazakhstan evaluated the extent of under-reporting and under-detection of COVID-19 cases from March 2020 to September 2022 using back-casting and capture-recapture methods. The results indicate that official case reporting in Kazakhstan significantly underestimates the number of infections by at least 50%. The study also suggests that improved testing capabilities may have led to a decrease in the percentage of unreported cases, however, early in the pandemic, Kazakhstan faced significant testing shortages. The study presents a mathematical model based on mortality data that highlights the severe under-reporting of COVID-19 cases in Kazakhstan and argues that understanding the true estimate of actual cases could aid in making informed decisions to end the pandemic.

RESUMEN

Chronic kidney disease (CKD) presents a significant global health challenge, often progressing to end-stage renal disease (ESRD) necessitating renal replacement therapy (RRT). Late referral (LR) to nephrologists before RRT initiation is linked with adverse outcomes. However, data on CKD diagnosis and survival post-RRT initiation in Kazakhstan remain limited. This study aims to investigate the impact of late CKD diagnosis on survival prognosis after RRT initiation. Data were acquired from the Unified National Electronic Health System (UNEHS) for CKD patients initiating RRT between 2014 and 2019. Survival post-RRT initiation was assessed using the Cox Proportional Hazards Model. Totally, 211,655 CKD patients were registered in the UNEHS databases and 9,097 (4.3%) needed RRT. The most prevalent age group among RRT patients is 45-64 years, with a higher proportion of males (56%) and Kazakh ethnicity (64%). Seventy-four percent of patients were diagnosed late. The median follow-up time was 537 (IQR: 166-1101) days. Late diagnosis correlated with worse survival (HR = 1.18, p < 0.001). Common comorbidities among RRT patients include hypertension (47%), diabetes (21%), and cardiovascular diseases (26%). The history of transplantation significantly influenced survival. Regional disparities in survival probabilities were observed, highlighting the need for collaborative efforts in healthcare delivery. This study underscores the substantial burden of CKD in Kazakhstan, with a majority of patients diagnosed late. Early detection strategies and timely kidney transplantation emerge as crucial interventions to enhance survival outcomes.

RESUMEN

Introduction: The COVID-19 pandemic triggered global health crises, affecting population health directly through infections and fatalities, and indirectly by increasing the burden of chronic diseases due to disrupted healthcare access and altered lifestyle behaviors. Amidst these challenges, concerns regarding reproductive health and fertility rates have emerged, necessitating an understanding of their implications for policymaking and healthcare planning. Furthermore, Kazakhstan's healthcare landscape underwent significant changes with the reintroduction of compulsory social health insurance system in January 2020, coinciding with the onset of the COVID-19 pandemic. This study aims to assess the impact of the COVID-19 pandemic and compulsory social health insurance system on fertility rates in Kazakhstan by examining live birth data from 2019 to 2024. Methods: Using Interrupted Time Series analysis, we evaluated the effect of the COVID-19 lockdown announcement and compulsory social health insurance system implementation on monthly birth rates, adjusted for the number of women of reproductive age from January 2019 to December 2023. Results: In the final model, the coefficients were as follows: the effect of the COVID-19 lockdown was estimated at 469 (SE = 2600, p = 0.8576); the centering variable was estimated at 318 (SE = 222, p = 0.1573), suggesting no significant trend in monthly birth rates over time; the insurance effect was estimated at 7,050 (SE = 2,530, p < 0.01); and the effect of the number of women of reproductive age was estimated at -0.204 (SE = 0.0831, p = 0.01). Discussion: The implementation of the compulsory social health insurance system, rather than the announcement of the COVID-19 lockdown, has had a significant positive impact on live birth rates in Kazakhstan. However, despite governmental efforts, live birth rates are declining, potentially due to unaddressed health needs of fertile women and economic challenges. Urgent policy-level actions are needed to address gaps in healthcare services and promote reproductive health.

RESUMEN

INTRODUCTION: Recognizing the importance of birth weight is fundamental to addressing public health challenges associated with maternal and child health. Birth weight serves as a critical indicator, offering insights into mortality, stunting, and the development of chronic diseases later in life. This study delves into fertility and infant mortality trends in Kazakhstan, with a specific focus on understanding urban-rural disparities and gender variations in mortality rates. OBJECTIVES: The primary objective of this study is to evaluate the influence of birth weight on infant mortality in Kazakhstan, considering demographic and regional nuances. Through comprehensive analysis, we aim to discern patterns and factors contributing to infant mortality, thereby informing targeted interventions and policies aimed at improving maternal and child health outcomes across the country. MATERIALS AND METHODS: The analysis was conducted using the data provided by the Republican State Enterprise on the PCV of the "Republican Centre for Electronic Health Care" of the Ministry of Health of Kazakhstan. RESULTS: In Kazakhstan, birth rates reached their zenith in 2021 (total 446,491 births). However, this figure experienced a downturn in 2022, declining to 403,893 births. Notably, urban regions consistently reported higher birth rates compared to rural areas. The year 2022 witnessed a decline in birth rates across both urban and rural populations, with decreases of 9.5% and 11.7%, respectively, compared to the previous year. Analysis using linear regression techniques on infant mortality rates spanning from 2017 to 2022 revealed no statistically significant time trend (slope=51.29, correlation coefficient=0.42, p=0.41). Gender-specific disparities in mortality rates were starkly evident, with boys exhibiting higher mortality rates compared to girls across all population subsets. Geographical analysis conducted in 2022 exposed significant divergences in mortality rates across various regions. CONCLUSIONS: The study highlights significant urban-rural disparities and gender differences in birth rates and infant mortality within Kazakhstan. It also confirms the protective effect of higher birth weight on infant mortality. Regional disparities suggest targeted public health interventions are necessary to address these variations effectively.

RESUMEN

Globally, cancer is the second leading cause of death, with a growing burden also observed in Kazakhstan. This study evaluates the burden of common cancers in Almaty, Kazakhstan's major city, from 2017 to 2021, utilizing data from the Information System of the Ministry of Health. In Kazakhstan, most common cancers among men include lung, stomach, and prostate cancer, while breast, cervical, and colorectal cancers are predominant among women. Employing measures like disability-adjusted life years (DALYs), we found that selected cancer types accounted for a total DALY burden of 25,016.60 in 2021, with mortality contributing more than disability (95.2% vs. 4.7%) with the ratio of non-fatal to fatal outcomes being 1.4 times higher in women than in men. The share of non-fatal burden (YLD) proportion within DALYs increased for almost all selected cancer types, except stomach and cervical cancer over the observed period in Almaty. Despite the overall increase in cancer burden observed during the time period, a downward trend in specific cancers suggests the efficacy of implemented cancer control strategies. Comparison with global trends highlights the significance of targeted interventions. This analysis underscores the need for continuous comprehensive cancer control strategies in Almaty and Kazakhstan, including vaccination against human papillomavirus, stomach cancer screening programs, and increased cancer awareness initiatives.

RESUMEN

During the period 2013-2023, 917 cases of rabies among animals were registered in the Republic of Kazakhstan. Out of these, the number of cases in farm animals amounted to 515, in wild animals to 50 and in pets to 352. Data on rabies cases were obtained from the Committee for Veterinary Control and Supervision of Kazakhstan, as well as during expeditionary trips. This research was carried out to demonstrate the use of modern information and communication technologies, geospatial analysis technologies in particular, to identify and visualize spatio-temporal patterns of rabies emergence among different animal species in Kazakhstan. We also aimed to predict an expected number of cases next year based on time series analysis. Applying the 'space-time cube' technique to a time series representingcases from the three categories of animals at the district-level demonstrated a decreasing trend of incidence in most of the country over the study period. We estimated the expected number of rabies cases for 2024 using a random forest model based on the space-time cube in Arc-GIS. This type of model imposes only a few assumptions on the data and is useful when dealing with time series including complicated trends. The forecast showed that in most districts of Kazakhstan, a total of no more than one case of rabies should beexpected, with the exception of certain areas in the North and the East of the country, where the number of cases could reach three. The results of this research may be useful to the veterinary service in mapping the current epidemiological situation and in planning targeted vaccination campaigns among different categories of animals.

RESUMEN

BACKGROUND: The health system performance assessment is a challenging process for decision-makers. In case of Kazakhstan's healthcare system, the calculation of avoidable mortality, which has been underutilized to date, could serve as an additional tool to prioritize areas for improvement. Therefore, the aim of the study is to analyse avoidable mortality in Kazakhstan. METHODS: The data was retrieved from the Bureau of National Statistics, Kazakhstan. It covers population data by age, mortality rates from disease groups based on the Joint OECD (Organisation for Economic Co-operation and Development)/Eurostat classification of preventable and treatable causes of mortality. The data spans from 2015 to 2021, categorized by gender and 5-year age groups (0, 1-4, 5-9, ..., 70-74). Standardization was performed using the 2015 OECD standard population. We used joinpoint regression analysis to calculate the average annual percentage change (AAPC). RESULTS: From 2015 to 2019, the annual percentage change (APC) in avoidable mortality per 100 000 population was -3.8 (-5.7 to -1.8), and from 2019 to 2021 it increased by 17.6 (11.3 to 24.3). Males exhibited higher avoidable mortality rates compared to females. The preventable mortality rate was consistently higher than the treatable mortality. Both preventable and treatable mortality decreased from 2015 to 2019, with preventable mortality reaching 272.17 before rising to 379.23 per 100 000 population in 2021. Between 2015 and 2021, treatable mortality rates increased from 179.3 (176.93-181.67) to 205.45 (203.08-207.81) per 100 000 population. CONCLUSION: In Kazakhstan, the leading causes of avoidable mortality were circulatory diseases, respiratory diseases, and cancer. To achieve the goals of universal health coverage (UHC) and improve the overall population health, there is an urgent need to amend the healthcare system and reduce avoidable mortality. While it is important to acknowledge the influence of COVID-19 on these trends, our study's focus on avoidable mortality provides valuable insights that complement the understanding of pandemic-related effects.

RESUMEN

OBJECTIVE: This study evaluates the impact of radioactive uranium waste storage facilities on cancer occurrence in nearby areas. METHODS: Current research evaluates the effect of radioactive uranium waste storage facilities on cancer epidemiology in nearby areas. The critical area had Aqsu, Kvartsitka, Zavodskoy and Stepnogorsk cities, which are located at a less than 5 km distance to the south of the Hydrometallurgical Plant tailings dump while the control group had Akkol region in 90 km from the source. The majority of population had lived in this territory more than the 30 years. Data were obtained from the Electronic Register of Cancer Patients of the Republic of Kazakhstan from 2001-2015, and 2,271 incident cases of cancer were registered. RESULTS: The most frequent malignancies were observed in the digestive organs (646 cases, 28%) and respiratory and intrathoracic organs (376 cases, 17%). The proportion of digestive organ cancers was higher in the critical group (560 cases out of 1913, 29%) than in the control group (86 cases out of 358, 24%). Additionally, respiratory organ cancers were more common in men, but the cancer incidence rate ratio was higher in the critical area. Notably, the study found that the cancer incidence rate ratios decreased over time, specifically for digestive, respiratory and female genital organs and breast cancer. CONCLUSION: In conclusion, while our study highlights significant differences in cancer incidence rates and frequencies between the critical and control groups, further analytical research, incorporating age-adjustment, is needed to provide a more conclusive evaluation of the potential impact of residence in proximity to the uranium mining waste storage on cancer occurrence in the study area.

RESUMEN

OBJECTIVE: To determine the demographic and clinical characteristics of individuals diagnosed with colorectal cancer. METHODS: A retrospective study was conducted on 650 patients diagnosed with colorectal cancer in West Kazakhstan from 2019 to 2023. Statistical analysis was performed to explore the relationships between various factors and outcomes, using significance tests and regression techniques. RESULTS: The study included 650 colorectal cancer patients, with 59.7% males and 40.3% females. Age distribution showed 63.1% between 24-65 years and 36.9% over 65, with no gender-based age differences. Nationality significantly influenced patient composition (63.8% Kazakh, 36.2% Russian, P=0.03). KRAS mutations (76.0% negative) and tumor morphology (40% adenocarcinoma, P=0.02) displayed varied associations. Univariate logistic regression revealed links between demographic/clinical factors and cancer outcomes. Multivariate analysis emphasized age, stage of cancer, expansion, involvement of lymphatic and metastasis in cancer progression. Nomogram predictive modeling incorporated gender, tumor form, stage, and infiltration. Evaluation in a validation cohort showed good differentiation (AUC=0.6293) and calibration. The findings provide insights into colorectal cancer demographics, progression, treatment, and mortality, aiding personalized interventions. CONCLUSION: this study reveals critical insights into demographics, treatment, and prognosis. Emphasizing the complexity of CRC, the study highlights age, gender, and tumor characteristics' impact on progression and mortality. A developed nomogram model offers clinicians a practical tool for personalized treatment decisions, enhancing prognosis discussions with patients.

RESUMEN

The population in the areas neighboring the Semipalatinsk Nuclear Test Site (SNTS) in the eastern region of Kazakhstan faces increased cardiovascular disease (CVD) risk. Previous research has not explored gene polymorphisms related to CVD in this population. Therefore, the present study examines the prevalence of six CVD-associated genotypes in three generations exposed to SNTS radiation. The genotyping of ApoE Leu28 → Pro, AGT Met174 → Thr, AGT Met235 → Thr, eNOS T786 → C, PON1 Gln192 → Arg, and EDN 1 Lys198 → Asn was performed using real-time polymerase chain reaction. The present study encompassed a cohort of 218 participants with a familial history of arterial hypertension and/or carotid artery disease spanning at least three generations. The analysis unveiled significant disparities in the prevalence of ApoE Leu28 → Pro, eNOS T786 → C, and PON1 Gln192 → Arg genotypes across different generations. Furthermore, a substantial variation in the distribution of the eNOS T786 → C genotype was observed between individuals of Kazakh and Russian ethnicities. Nevertheless, no significant discrepancies were detected in the frequencies of the investigated genotypes between genders. Further research in this area is warranted to enhance the understanding of the genetic factors contributing to CVD in the population exposed to radiation from the SNTS. Specifically, future studies should broaden the scope of genetic polymorphisms investigated and include representatives of healthy individuals who have not been exposed to radiation as controls.

RESUMEN

BACKGROUND: Anthrax is the most prioritized zoonotic disease in Kazakhstan due to its threatening potential to the public health and agricultural sector. Sporadic anthrax outbreaks are being reported annually among human and livestock populations throughout the country, with the highest frequency occurring in West Kazakhstan. METHODS: A cross-sectional study was conducted using a survey-based face-to-face interview. From January to May 2022, 489 randomly selected participants were surveyed in 6 districts of the Baiterek province in West Kazakhstan oblast to evaluate the knowledge, attitude and practice (KAP) regarding anthrax among community members. This is the first KAP study conducted relating to outbreaks of anthrax in Kazakhstan. RESULTS: In this study, most participants (74%) surveyed were males, and 40% of respondents had a secondary level education. Overall, 91% of the community respondents were engaged in agriculture and livestock rearing. Among these community members, cattle rearing was the most common (67%) occupation compared to other livestock species. Additionally, over a 50% of the population studied had no knowledge about the zoonotic nature of the disease, and about 82% and 87% of respondents were unaware of any animal and human anthrax symptoms, respectively. About 70% of the respondents were interested in vaccinating their livestock against anthrax. Individuals aged 45-54 displayed notably higher animal vaccination rates (45%; 95% CI: 38.4-52.0; p < 0.025) compared to those aged 25-34 and 65-74. Respondents residing in the Beles district (20%; 95% CI: 17.1-24.7; p < 0.005) exhibited a significantly higher level of awareness concerning the fatality of anthrax in contrast to participants from Bolashak. Roughly 61% of respondents held the belief that anthrax is a lethal disease. An overwhelming majority of the survey participants (99%) affirmed their non-participation in the slaughter of infected animals. CONCLUSION: The findings of this study indicate that KAP among community members relating to anthrax is low and requires swift implementation of education programmes in building awareness of anthrax under the One Health approach, especially in anthrax prone regions.

RESUMEN

INTRODUCTION: Removing legal barriers to HIV services is crucial for the global 2030 goal of ending the HIV and AIDS epidemic, particularly in eastern Europe, the Caucasus and central Asia. Despite state commitments to uphold human rights, gay, bisexual and other men who have sex with men (gbMSM), along with transgender people (TP) still face stigma and discrimination. This article presents an analysis of rights violations based on sexual orientation and gender identity (SOGI) and HIV reported in 2022 across six countries, highlighting features and their links to legislation and law enforcement practices. METHODS: We examined documented cases of rights violations among gbMSM and TP in Armenia, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and Ukraine in 2022 using the REAct system, a tool for documenting and responding to rights violations against key populations. Initially, we employed directed content analysis based on Yogyakarta Principles to analyse narratives of violations. A codebook was developed through contextual, manifest and latent coding, with themes, categories and codes converted into quantitative variables for statistical analysis. Descriptive statistics were used to identify the characteristics of violations. RESULTS: A total of 456 cases of rights violations related to SOGI and HIV were documented, ranging from 22 cases in Tajikistan to 217 in Ukraine. Most violations concerned gbMSM (76.5%), with one-fifth involving TP, predominantly transgender women. Complex violations with multiple perpetrators or infringements were documented in Armenia and central Asia. Privacy rights were commonly violated, often through outing. Cases of violations of the right to the highest attainable standard of health (13.6%) and protection from medical abuses (2.6%) were also documented. Other rights violations were sporadic, with each country exhibiting distinct patterns of violated rights and types of violations. In Ukraine, the full-scale war in 2022 influenced the nature of documented cases, reflecting the challenges faced by gbMSM and TP. CONCLUSIONS: Monitoring rights violations proved effective for assessing the situation of gbMSM and TP, particularly in the insufficiently studied and diverse eastern Europe, Caucasus and central Asia regions. As rights violations are linked to both legislation and law enforcement practices, comprehensive interventions to minimize structural and interpersonal stigma are essential.

RESUMEN

INTRODUCTION: There is a research gap in how mental health and cognition are associated with antiretroviral treatment (ART) adherence among people living with HIV (PLWH) in Kazakhstan. METHODS: We randomly selected and enrolled 230 PLWH from the Almaty City AIDS Center registry (June-November 2019) into a cross-sectional study. We examined associations between self-reported ART adherence for the last 1 and 2 weeks; the Adherence Self-Efficacy Scale (ASES) and symptoms of depression (Patient Health Questionnaire-9 [PHQ-9]), anxiety (Generalized Anxiety Disorder tool [GAD-7]), post-traumatic stress disorder (PTSD Checklist [PTSD]); cognitive function (PROMIS v2.0 Adult Cognitive Function 8a short form) and forgetfulness (Forgetfulness Assessment Inventory). We used cut points of ≥5 for at least mild and ≥10 for at least moderate symptom severity for PHQ-9 and GAD-7 and of ≥44 for PTSD. Logistic and linear regression analyses were used. RESULTS: Participants' median age was 40.0 (IQR: 34-47) with 40.9% (n = 94) of females in the sample. Those who missed at least one pill for the last 2 weeks had higher odds of reporting at least mild depression (aOR = 3.34, 95% CI: 1.22-9.11, p < 0.05); mild anxiety (aOR = 3.27, 95% CI: 1.20-8.92, p < 0.05); and PTSD (aOR = 4.04, 95% CI: 1.15-14.21, p < 0.05) symptoms. Participants who missed at least one pill for the last week had higher odds of at least mild depression (aOR = 7.74, 95% CI: 1.31-45.7, p < 0.05), moderate anxiety (aOR = 21.33, 95% CI: 3.24-140.33, p < 0.005) and PTSD (aOR = 13.81, 95% CI: 2.36-80.84, p < 0.005) symptoms. Participants with better cognitive function had lower odds of non-adherence over the last week (aOR = 0.88, 95% CI: 0.81-0.96, p < 0.005) and higher ASES scores (ß = 0.26, 95% CI: 0.13-0.40, p < 0.005). Poor memory was associated with higher odds of non-adherence over the last week (aOR = 4.64, 95% CI: 1.76-12.24, p < 0.005) and lower ASES score (ß = -0.31, 95% CI: -0.45 to 0.16, p < 0.005). Those who had at least mild depression (ß = -0.21, 95% CI: -0.35 to -0.07, p < 0.005); moderate anxiety (ß = -0.21, 95% CI: -0.34 to -0.07, p < 0.005) and PTSD (ß = -0.19, 95% CI: -0.33 to -0.05, p < 0.005) symptoms had lower ASES scores. CONCLUSIONS: Depression, anxiety and PTSD symptoms, poorer cognition, and forgetfulness were associated with poorer ART adherence and worse adherence self-efficacy. It is crucial to assess and treat mental illness and provide support for PLWH with worsened cognition to enhance ART adherence.

RESUMEN

HIV testing is the point of entry for linkage to treatment and prevention and is critically important to ending the HIV epidemic. HIV self-testing (HST) is an acceptable, user-controlled tool that can address testing barriers, which is especially important for populations who need to test frequently, like women who exchange or trade sex for money or other needed resources (WES) and women who use drugs. HST is feasible and acceptable among WES, but research among WES who also use drugs is limited, particularly in places like Kazakhstan, where HIV rates remain high and where scale-up of HST and pre-exposure prophylaxis (PrEP) is in process. To develop effective programming, there is a need to develop tailored services for WES and/or use drugs that address key barriers. We discuss opportunities to increase HST and linkage to services among WES and/or use drugs in Kazakhstan, with a focus on stigma reduction.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate the relationship of soil pollution factors such as heavy metal ions with the incidence of cancer in the Kyzylorda region of Kazakhstan. METHODS: Concentrations of heavy metal ions in the soils of different sites of Kyzylorda region, Kazakhstan, were sampled and correlated with incidence of cancer in 2021. RESULTS: Chromium content in the soil exceeded maximum permissible concentration (MPC) in the samples for all sites except Kazaly and Shieli, and the highest excess of 2.8 MPC was found in Terenozek. Content of copper, lead, and cobalt ions was also increased and varied in the range 1.9-15.4, 1.2-4, and 1.2-2.44 MPC, respectively. In addition, lung cancer incidence was statistically significantly correlated with soil concentration to MPC ratio of copper, cobalt, and lead; colorectal cancer was correlated with soil concentration of chromium. Cases of invasive cancer and mutations were recorded Terenozek and Kyzylorda areas. CONCLUSION: The higher the soil concentration correlate with higher cancer incidence in Kyzylorda region, Kazakhstan.

RESUMEN

Cervical cancer (CC) continues to be a significant global health issue, which in part can be attributed to disparities in access to CC screening services. This study aims to conduct a trend of CC in Kazakhstan and to compare attitudes towards the screening program between women living in urban and rural areas. In the first stage, we conducted a trend study of CC indicators in Kazakhstan using official statistics. In the second stage, a cross-sectional study was conducted using a structured questionnaire to assess adherence to screening. The trend study reveals a decline in cervical cancer mortality rates (from 7.15 to 5.93 per 100,000 female inhabitants) over the period studied, while the incidence remains stable (from 18.51 to 19.38 per 100,000 female inhabitants). Regional variations in Period Prevalence rates were observed. Significant differences were found in screening participation rates between urban n = 41 (74%) and rural n = 23 (38%) women, p < 0.001, as well as awareness of the screening program (urban: n = 15 (27%), rural: n = 35 (58%), p < 0.001). The trend study highlights a decrease in cervical cancer mortality rates over the specified period, accompanied by a consistent incidence rate. Additionally, regional disparities in period prevalence rates of cervical cancer were observed. The primary factor contributing to the low adherence of rural women to screening was found to be a lack of awareness regarding the screening program. Therefore, increasing awareness about the importance of screening is crucial for improving adherence rates among rural women in Kazakhstan.

RESUMEN

Osteoporosis is considered a serious public health problem that particularly affects the postmenopausal period. In 2018, in the Republic of Kazakhstan, the prevalence of osteoporosis was 10.0, and the incidence was 3.7 new cases, per 100,000 adults, respectively. The objective of this study was to assess the prevalence of osteoporosis and indicate the main factors affecting low bone mineral density by screening the adult population of the Abay region, Kazakhstan. The target group comprised 641 respondents aged between 18 and 65 years old, from a Kazakh population, who had been living in the Abay region since birth. All participants filled out a questionnaire and were subjected to a bone mineral density measurement by means of dual-energy X-ray absorptiometry (DXA) between 15 July 2023 and 29 February 2024. Logistic regression analysis was conducted to assess the association between low bone mineral density and key demographic characteristics, such as lifestyle factors and nutritional habits. We identified the prevalence of low bone mass (osteopenia) and osteoporosis to be 34.1%, with the highest prevalence of 48.3% being found in the older population group (50+ years). The regression analysis revealed a number of indicators associated with the likelihood of bone sparing. However, only four of these showed significance in the final multivariate model (R2 = 22.4%). These were age (adjusted odds ratio (AOR) 1.05) and fracture history (AOR 1.64) directly associated with the likelihood of low bone density. Meanwhile, the body mass index (AOR 0.92) and the consumption of nuts and dried fruits (AOR 0.48) reduced the chance of bone tissue demineralization. Additional studies examining the prevalence and any emerging risk factors for osteoporosis are needed to advance clinical epidemiological knowledge and implement public health programs.

RESUMEN

Introduction: The maternal mortality indicator serves as a crucial reflection of a nation's overall healthcare, economic, and social standing. It is necessary to identify the variations in its impacts across diverse populations, especially those at higher risk, to effectively reduce maternal mortality and enhance maternal health. The global healthcare landscape has been significantly reshaped by the COVID-19 pandemic, pressing disparities and stalling progress toward achieving Sustainable Development Goals, particularly in maternal mortality reduction. Methods: This study investigates the determinants of maternal mortality in Kazakhstan from 2019 to 2020 and maternal mortality trends in 17 regions from 2000 to 2020, employing data extracted from national statistical reports. Stepwise linear regression analysis is utilized to explore trends in maternal mortality ratios in relation to socioeconomic factors and healthcare service indicators. Results: The national maternal mortality ratio in Kazakhstan nearly tripled from 13.7 in 2019 to 36.5 per 100,000 live births in 2020. A remarkable decrease was observed from 2000 until around 2015 with rates spiked by 2020. Significant factors associated with maternal mortality include antenatal care coverage and the number of primary healthcare units. Additionally, socioeconomic factors such as secondary education enrollment and cases of domestic violence against women emerged as predictors of MMR. Moreover, the impact of the pandemic was evident in the shift of coefficients for certain predictors, such as antenatal care coverage in our case. In 2020, predictors of MMR continued to include secondary education enrollment and reported cases of domestic violence. Conclusion: Despite Kazakhstan's efforts and commitment toward achieving Sustainable Development Goals, particularly in maternal mortality reduction, the impact of the COVID-19 pandemic poses alarming challenges. Addressing these challenges and strengthening efforts to mitigate maternal mortality remains imperative for advancing maternal health outcomes in Kazakhstan.

RESUMEN

INTRODUCTION: Cardiovascular disease (CVD) presents a significant challenge in rheumatoid arthritis (RA), a systemic chronic ailment affecting the joints and causing systemic inflammation. Effective RA management, including pharmacological and non-pharmacological interventions, is crucial for mitigating cardiac risk. Pharmacotherapy, though effective, can have adverse effects, leading many patients to seek complementary therapies. This study investigates the impact of physical medicine and rehabilitation on RA management in patients with cardiovascular disease, analyzing clinical data to assess the efficacy of integrated therapeutic approaches. METHODS: This retrospective monocentric study draws upon data from patient records at the Rheumatology Department of the Regional Clinical Hospital of Shymkent, Kazakhstan, spanning 2019 to 2022. Data collected included demographic information, diagnoses, comorbidities, medical anamneses, lab results, and treatment regimens, including physical medicine and rehabilitation interventions. Data were summarized in Microsoft Excel. Statistical analysis was performed using IBM SPSS Statistics (version 26.0). RESULTS: An analysis of 350 patients with RA identified 143 cases of concomitant CVD, with arterial hypertension being the most common cardiovascular disease. The prevalence of CVD among patients with RA was 40%, with a mean age of 58 years, peaking between 50 and 65 years. The majority of patients were women. A strong association was found between increased RA activity and elevated cardiovascular risk. Despite the widespread use of glucocorticosteroid therapy, rehabilitation coverage remained limited. A significant proportion of patients had elevated cholesterol and C-reactive protein levels, while those who engaged in physical therapy and rehabilitation had lower cholesterol levels. Comparative analysis of yoga integration into rehabilitation programs for patients with RA, alongside other modalities (kinesiotherapy, balneotherapy, and pilates), showed that yoga participants exhibited lower pain levels, reduced morning stiffness duration, and lower mean DAS-28 scores compared to those using alternative rehabilitation methods. CONCLUSION: Integrating physical medicine and rehabilitation, particularly yoga, with pharmacological treatments appears promising for improving patient outcomes. Yoga has demonstrated benefits in reducing pain, morning stiffness, and disease activity. Continued research is essential to refine these approaches and enhance RA and CVD management in patients.

RESUMEN

Type 2 diabetes mellitus (T2DM) is a socially significant disease with increasing prevalence worldwide. It is characterized by heterogeneous metabolic disorders and is associated with various risk factors, including BMI, abnormal lipid levels, hypertension, smoking, dietary preferences, physical inactivity, sedentary lifestyle, family history of diabetes, prediabetes or gestational diabetes, inflammation, intrauterine environment, age, sex, ethnicity, and socioeconomic status. Assessing the genetic risk of developing T2DM in specific populations remains relevant. The ADIPOQ gene, encoding adiponectin, is directly related to the risk of developing T2DM, obesity, and cardiovascular diseases. Our study demonstrated significant associations of ADIPOQ gene polymorphisms with the risk of developing T2DM and obesity, as well as with fasting glucose levels and BMI, in the Kazakh population. Specifically, rs266729 was significantly associated with T2DM and obesity in the Kazakh population, while other studied polymorphisms (rs1501299, rs2241766, and rs17846866) did not show a significant association. These findings suggest that ADIPOQ gene polymorphisms may influence T2DM risk factors and highlight the importance of genetic factors in T2DM development. However, further research in larger cohorts is needed to confirm these associations.
