Background and Objectives: Sexualized substance use (SSU) and chemsex have garnered increasing attention in public health research, particularly among men who have sex with men (MSM). However, the prevalence and implications of these behaviors in the general population and among women remain underexplored. This systematic review and meta-analysis aimed to synthesize existing evidence on the prevalence of SSU and chemsex in the general population, with a specific focus on women. Materials and Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, PubMed, ProQuest, Scopus, Web of Science, Cochrane, and PsycINFO were searched for studies published before 18 February 2025. The keywords included “chemsex”, “sexualized substance use”, “prevalence”, and “women”. Studies were included if they reported prevalence data on SSU or chemsex in the general population or among women. The exclusion criteria included studies focused exclusively on MSM, adolescents, or specific drug toxicity. The pooled prevalence estimates were presented using forest plots, and the heterogeneity was assessed using I² statistics in RStudio (version 4.3.2). Results: The findings reveal that SSU and chemsex are significant phenomena, with pooled prevalences of 19.92% in the general population and 15.61% among women. The higher prevalence of SSU (29.40%) compared with chemsex (12.66%) in the general population suggests that substance use during sex is a broader behavioral pattern. Among women, the prevalence of chemsex was notably lower (3.50%) than SSU (25.78%). Conclusions: This study underscores that SSU and chemsex are significant public health concerns extending beyond the MSM community. The findings highlight the need for inclusive public health strategies that address these behaviors across the general population. Future research should focus on standardizing definitions, exploring contextual factors, and developing targeted interventions to mitigate associated risks, such as sexually transmitted infections, substance dependency, and mental health disorders.

Background: This study examines the levels and predictors of malnutrition in Indian children under 5 years of age. Methods: Composite Index of Anthropometric Failure was applied to data from the India National Family Health Survey 2019–2021. A multivariable logistic regression model was used to assess the predictors. Results: 52.59% of children experienced anthropometric failure. Child predictors of lower malnutrition risk included female gender (adjusted odds ratio (AOR) = 0.881) and average or large size at birth (AOR = 0.729 and 0.715, respectively, compared to small size). Higher birth order increased malnutrition odds (2nd-4th: AOR = 1.211; 5th or higher: AOR = 1.449) compared to firstborn. Maternal predictors of lower malnutrition risk included age 20–34 years (AOR = 0.806), age 35–49 years (AOR = 0.714) compared to 15–19 years, normal BMI (AOR = 0.752), overweight and obese BMI (AOR = 0.504) compared to underweight, and secondary or higher education vs. no education (AOR = 0.865). Maternal predictors of higher malnutrition risk included severe anemia vs. no anemia (AOR = 1.232). Protective socioeconomic factors included middle (AOR = 0.903) and rich wealth index (AOR = 0.717) compared to poor, and toilet access (AOR = 0.803). Children’s malnutrition risk also declined with paternal education (primary: AOR = 0.901; secondary or higher: AOR = 0.822) vs. no education. Conversely, malnutrition risk increased with Hindu (AOR = 1.258) or Islam religion (AOR = 1.369) vs. other religions. Conclusions: Child malnutrition remains a critical issue in India, necessitating concerted efforts from both private and public sectors. A ‘Health in All Policies’ approach should guide public health leadership in influencing policies that impact children’s nutritional status.

Background and Objectives: Despite frequent references to the high prevalence of vitamin D deficiency in Kazakhstan, a comprehensive synthesis of existing research on this issue among adults is lacking. This systematic review and meta-analysis aim to address this gap by determining the mean prevalence of vitamin D deficiency among adults in Kazakhstan. A secondary objective is to evaluate whether the prevalence differs between healthy adults and those with chronic conditions. Materials and Methods: A systematic search was conducted in PubMed, Scopus, ScienceDirect, Web of Science, and Google Scholar by two independent researchers using the keywords: “vitamin D” AND “Kazakhstan”, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were included if they reported the prevalence of vitamin D in adults in Kazakhstan, defined as a blood level of 25-hydroxyvitamin D 25(OH)D below 20 ng/mL. Results: Seven studies were included in this review, encompassing 3616 individuals, of whom 2239 had vitamin D deficiency. Using a random-effects model, the pooled mean prevalence of vitamin D deficiency among adults with chronic conditions was 60% (95% CI, 38–79%), with high heterogeneity. Similarly, the analysis of five studies involving healthy adults revealed a pooled mean prevalence of 55% (95% CI, 38–70%), also with high heterogeneity. Overall, the pooled mean prevalence of vitamin D deficiency in the adult population was 57% (95% CI, 45–69%). Conclusions: This analysis indicates a high prevalence of vitamin D deficiency among adults in Kazakhstan, with 57% of the population affected. Addressing this issue requires a multifaceted approach, including policy reforms that consider the impact of time zone changes on sunlight exposure and the active involvement of nurse practitioners in preventive strategies.

This study aims to systematically review the current literature on published studies with data on the clinical significance of endometrial thickness on ultrasound for live birth rate (LBR) after in vitro fertilization (IVF) procedures. A comprehensive systematic review of PubMed, Web of Science, ScienceDirect, Google Scholar, and Open Gray databases and a subsequent hand search of the reference list of included studies was performed. We found 20 eligible studies that evaluated 20 546 patients for endometrial thickness, presented risk factors for decreased endometrial receptivity, and IVF outcomes with fresh and frozen embryo transfer (FET) cycles. The mean age of the patients ranged from 28.86 to 41.03 years. Reported endometrial thickness ranged from 15 mm. The clinical pregnancy rate varied from 9,09% to 61,49% in fresh embryo transfer cycles and from 13,3% to 79,31% in FET cycles. Overall, LBR varied between 4,80% and 48,99% in fresh embryo cycles and between 6.06% and 39,19% in FET cycles. Limitations. Only English-language studies were included; most studies were from the China region; retrospective study design used in most studies; different ET thresholds, which in turn could significantly alter the correlation with pregnancy outcomes; different IVF procedure protocols in fresh or FET cycles. IVF outcomes in patients with impaired endometrial receptivity do not depend only on the condition of the endometrium. Risk factors and endometrial thickness significantly affect LBR in fresh and FET cycles. (www.actabiomedica.it)

Introduction: Cardiovascular disease, type 2 diabetes, and stroke are significant global health concerns. However, gaps persist in understanding the impact of these disorders on women of reproductive age in Central Asia. This study aimed to analyze the health policies implemented in Central Asian countries to address the healthcare needs of this demographic and to forecast future trends in prevalence rates.Methodology: We forecasted future trends in prevalence rates, years of life lost, years lived with disability, and disability-adjusted life years for cardiovascular disease, type 2 diabetes, and stroke using publicly available data. Two data sources were utilized: health policy documents issued by the governments of Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, and Turkmenistan, and data from the Institute for Health Metrics and Evaluation. Forecasting models, including ARIMA, were employed to predict trends until 2030.Results: The results indicate an anticipated increase in cardiovascular disease prevalence from 1856.55 in 2020 to 2007.07 by 2029 in Kazakhstan, a subtle increase in Kyrgyzstan from 2492.22 to 2558.69 over 10 years, and similar trends in other countries.Conclusion: The analysis of policy documents revealed a lack of specific focus on addressing cardiovascular disease, stroke, or type 2 diabetes outside the contexts of pregnancy and childbirth. Understanding these trends is crucial for informing targeted health interventions and resource allocation to mitigate the impact of these diseases on women’s health in Central Asia.

Introduction: Diagnosis of breast cancer is associated with the presence of psychological disorders including depression. There is a lack of study examining the prevalence of depression among newly diagnosed breast cancer patients in Kazakhstan. Objective: This study aims to assess the prevalence and associated sociodemographic and clinical factors of depression symptoms in women newly diagnosed with breast cancer. Methods: 162 newly diagnosed breast cancer patients at the oncology center in Almaty were recruited for this study. Data were collected using a structured questionnaire on sociodemographic and clinical information and the Beck Depression Inventory-II scale. Results: The mean age of the patients was 54.41 years (SD=8.1). 95% of participants had unilateral breast cancer, and 79% of participants had stage I or stage II breast cancer. 73% of patients said that they do not have reliable social support. 46% of patients had symptoms of moderate depression, and 31% of patients had symptoms of severe depression. According to the multivariate analysis, factors associated with depression symptoms were: social status, household income level, reliability of social support, and stage of breast cancer. Conclusion: The prevalence of depression symptoms is very high among newly diagnosed breast cancer patients. Unemployed or retired patients, with a lower household income, and no reliable social support diagnosed with an advanced stage of breast cancer are especially at high risk for developing depression.
