Health-care Accessibility Assessment in Kazakhstan

BACKGROUND: Global health initiatives such as health for all and universal health coverage aim to improve access to health care. These goals require constant comprehensive monitoring to eliminate inequalities in the availability of health care. AIM: The purpose of our study was to assess the physical availability of medical care in Kazakhstan. METHODS: A descriptive study based on a Service Availability and Readiness Assessment (SARA) general availability index calculation that used secondary data as a source of information. RESULTS: The general availability index calculated for the regions of Kazakhstan ranged from 95% to 100%. When considering individual indicators of the index, decrease trends of the volume of inpatient care were identified. Outpatient care had fluctuations with values better than benchmark after 2009. Stable upward trend illustrates positive picture of core health personnel. CONCLUSION: According to the SARA availability index, it can be concluded that health care in Kazakhstan exceeds the threshold values and is available in all regions. Trends for individual indicators of the index should be studied in more detail, taking into account the influence of health policy and other factors

Testosterone and occupational burnout in professional male firefighters

Background: Very little is known about the biologic predictors of the occupational burnout in firefighters. The aim of this study was to characterize testosterone profile of active firefighters and quantify its association with three domains of the occupational burnout. Methods: We enrolled 100 firefighters (median age 28 (interquartile range (IQR) 9.8) years with 5 (IQR 9) years in service) of three fire departments in Almaty, Kazakhstan. Demographics, smoking status, health-related quality of life (HRQL) and burnout scores of Maslach Burnout Inventory were assessed using a questionnaire, while total blood testosterone was measured in venous blood. Logistic regression models were used to quantify the association of blood testosterone with each burnout domain in the adjusted for confounders models. Results: The median blood testosterone level was 14 (IQR 3.5) nmol/l and was only predicted by age (beta − 0.14, p < 0.01, 79% power). There were no differences in blood testosterone levels between occupational groups (Group1 (firefighters), 14.6 (IQR 3.4); Group 2 (fire truck drivers), 14.7 (IQR 5.6); Group 3 (shift commanders, division heads,department managers and engineers), 14 (IQR 4.1) nmol/l, Kruskal-Wallis p = 0.32) or departments. Testosterone could not predict EX or CY, but had a negative association with PE score reflecting more burnout (odds ratio 1.18 (95% confidence interval 1.01;1.38)), adjusted for age, mental component of HRQL and education. Conclusions: Firefighters with higher testosterone may develop burnout in PE earlier, and this should be considered for proper work placement within the rescue system

Effectiveness of vitamin A supplementation among children under 5 years old in Kazakhstan

Micronutrient sufficiency leads to high rates of morbidity and mortality among children in Kazakhstan. Kazakhstan does not have a program for mandatory vitamin A supplementation of children under 5 years of age. Thus, the aim of this study was to assess the effectiveness of a pilot vitamin A supplementation program among children in Kazakhstan with the ultimate goal of informing future vitamin supplementation efforts. In Akmola and Kostanay regions of Kazakhstan, 529 children (aged 6-59 months) were randomly selected in each region through the local policlinics. In the first step of the study, mothers of the children were surveyed about the health status of their children using a standard data collection tool. Children were supplemented with Vitamin A using oral at a dose of 100,000 IU for children aged 6-11 months and 200,000 IU for children aged 12-59 months. Blood serum samples were collected for determining Vitamin A status. In the second step of the study, mothers were interviewed again about the health status of their children 6 months after the intervention and blood serum samples were collected to assess the efficacy of Vitamin A supplementation program. The number of self reported diarrhea cases and other intestinal infections significantly decreased after the vitamin A supplementation. The number of children with normal level of Vitamin A signficantly increased from before to after the intervention.  Data from all participants (n = 529; pre VAS and 501 post VAS) showed that mean serum retinol levels increased significantly post VAS from 30.01 ±0.5 µg/dL to 61.06 ±1.2 µg/dL (p <0.001) Likewise, a significant change was observed in the cases of reported diarrhea between pre-test and post-test assessments (30 vs. 95; p <0.01). The health status of the examined children in the Akmola and Kostanay regions had significantly improved after the vitamin A supplementation and it points to the necessity of implementing Vitamin A supplementation program on the national level. This study has important policy implications for recommending the supplementation program on the national scale

Occupational exposure to fine particulate matter in the reinforced concrete production and its association with respiratory symptoms and lung function

Abstract Background Reinforced concrete production is widespread, but little is known about the occupational exposure to fine particulate matter (PM) in such workplaces, including from metalworking and concrete processing. Therefore, the aim was to characterize exposure to fine PM in the typical workplaces of the whole production cycle and to quantify the risk of respiratory symptoms and lung function in a cohort of reinforced concrete parts production industry. Methods At a reinforced concrete parts producing facility in Almaty, we collected 50 personal PM2.5 samples from the main exposure sites and the measured mass concentrations using gravimetric method. Workers also completed questionnaires on a detailed working history, respiratory symptoms (chronic obstructive pulmonary disease (COPD) Assessment Tool (CAT)), followed by spirometry. The association of cumulative dose with CAT score and forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) was tested with multiple regression. Results The highest PM2.5 concentrations were found in the concrete-mixing unit (median 1180 µg/m3), followed by metalworking (510 µg/m3), armature workshop (375 µg/m3) and molding site (245 µg/m3), different from the concentrations in the office (29.5 µg/m3), Kruskall-Wallis p < 0.001. Cumulative PM2.5 dose, mg/m3-year (beta 0.10 (95% confidence interval (CI) 0.05; 0.15)) was strongly associated with CAT score, whereas production with FEV1/FVC (beta -4.96 (-8.31; -1.61)), independent of smoking and chronic bronchitis and sex. Conclusions Mixing concrete and metalworks pose the greatest risk for worker’s health in the reinforced concrete production from the inhalational exposure to aerosol, adversely affecting respiratory health

Exposure to Respirable Particulate Matter and Its Association with Respiratory Outcomes in Beauty Salon Personnel

We aimed to assess exposure to respirable particulate matter (PM) of beauty salon personnel, identify its determinants and ascertain the associated respiratory effects. We collected 122 full-day respirable PM samples from 12 beauty salons (floor area ranging from 24 to 550 m3, staff from 4 to 8) in Almaty, Kazakhstan, taking 10 samples from each place using a portable SidePak AM520 monitor. We also assessed lifestyle (smoking, etc.), respiratory symptoms and health-related quality of life (HRQL) of the personnel using questionnaires. Out of 11,831 5-min data points, daily median respirable PM concentrations were highly variable and ranged from 0.013 to 0.666 mg/m3 with 8.5-times difference in the median concentrations between the venue with the highest median (0.29 mg/m3) and the least median (0.034 mg/m3). In a multivariate linear regression modelling, ambient PM2.5 concentration was the strongest predictor of daily median respirable PM concentration (beta 2.12; 95% CI 1.89; 2.39), and R2 of the model was 0.63. We also found a positive association of the median respirable PM with respiratory symptoms and seasonal allergy, but not with HRQL. Short-term respirable PM levels in the beauty salons may be very high, but the median concentrations are mainly determined by the ambient air pollution

Medico-social effectiveness of biological monitoring of iodine deficiency status (IDS) among women of reproductive age in Kazakhstan

Introduction Iodine deficiency is one of the most important public health problems in the world. It mostly affects pregnant women and children. The lack of iodine leads to an increase in the numbers of perinatal mortality and mental retardation. Material and methods In 2012–2014, a survey was carried out of 2,342 women, of whom 2284 were analyzed for salt to measure the content of iodine, and 2,242 women of reproductive age had their urine samples analyzed by the cerium-arsenite method based on the Sandell-Kolthoff reaction. Determination of the medical and social effectiveness of biological monitoring of IDS was carried out in 3 stages. Results The study revealed that in the eastern Kazakhstan region the relative risk (RR) of overall prevalence of iodine deficiency among women was 1.1 times higher (95% ID: 0.35–3.61; Z statistic = 0.192) among household respondents (≤15mkg/kg). In the Pavlodar region, the RR of the prevalence of total iodine deficiency is 0.5 times higher in households where the salt was not sufficiently iodized. In the Zhambyl region the RR of the iodine deficiency prevalence was about twice as high due to insufficient iodized salt. Conclusions The introduction of biological monitoring of IDS among women, especially pregnant women, may positively affect the detection of the risk limits for the birth of infants with reduced mental abilities or other diseases during pregnancy, using timely targeted preventive measures to exclude factors that affect the spread of IDS

Asthma control in Kazakhstan: need for urgent action

Background Asthma control, patients’ awareness level and adherence to treatment in Kazakhstan have never been studied. The aim of this study was to verify the prevalence of controlled, poorly controlled and uncontrolled asthma in a large sample of three largest cities of Kazakhstan. Methods We recruited 600 (median age 54 (interquartile range (IQR) 22) years, 64% females) patients with diagnosis confirmed earlier in the outpatient facilities in Almaty, Astana and Shymkent in 2020–2021. We offered a structured questionnaire on asthma control and risk factors as of GINA and performed spirometry. We report the prevalence of asthma control, knowledge and skills and pharmacological treatment with 95% confidence interval (CI) and the association of selected predictors with asthma control. Results With the median of 9 (IQR 13) years of diagnosis, 40% of patients had comorbid COPD and 42% had allergic rhinitis, whereas 32% lived with pets. Asthma was well-controlled in only 12.3% (95% CI 9.7–15.0), partly controlled in 29.8% (95% CI 26.2–33.5) and uncontrolled in 57.8% (95% CI 53.9–61.8) patients. ACQ-5 score (range 0–5.8, median 2) equaled 0.2 (IQR 0.85) in well-controlled asthma patients, 1.4 (IQR 1) in partly controlled and 2.8 (IQR 1.4) in uncontrolled asthma patients. Knowledge and skills levels were very low. Only 54% were on inhaled corticosteroids (52.2% of them used budesonide/formoterol and 39.5% used fluticasone/salmeterol). 39% used steroids per os or parenterally within a period of 12 months (51% of patients with uncontrolled asthma). Conclusion Asthma control, knowledge and skills levels of asthma patients in the largest cities of Kazakhstan remain unacceptably low, whereas pharmacological treatment is far from optimal. Urgent action should be taken to support doctors’ training, and we call to launch a national asthma program to coordinate asthma care in Kazakhstan
