Detection of respiratory viruses and expression of inflammatory cytokines in patients with acute exacerbation chronic obstructive pulmonary disease in Mongolia China / Detecção de vírus respiratórios e expressão de citocinas inflamatórias em pacientes com doença pulmonar obstrutiva crônica de exacerbação aguda na Mongólia, China

Chronic obstructive pulmonary disease (COPD) was estimated to be the third cause of global mortality by 2020. Acute exacerbation COPD (AECOPD) is a sudden worsening of COPD symptoms and could be due to virus/bacterial infections and air pollution. Increased expression of inflammatory markers in patients with AECOPD is associated with viral infection. This study aimed to detect different viruses and analyze the expression of various inflammatory markers associated with AECOPD patients. Three hundred and forty-seven patients diagnosed with COPD according to GOLD criteria were included in this study. Swab samples and blood were collected for the detection of viruses by RT-PCR and expression of inflammatory markers, respectively. Of the swab samples, 113 (32.6%) of samples were positive for virus detection. Of these, HRV (39.8%) was the predominant virus detected followed by FluB (27.4%) and FluA (22.1%). The presence of HRV was significantly higher (p=0.044) among the other detected viruses. When compared to healthy controls the expression levels of TNF-α, IL-6 and IL-8 were significantly higher (p<0.05) in virus-positive patients. The IL-6 and IL-8 were the next predominantly expressed in markers among the samples. The higher expression rate of IL-8 was significantly (p<0.05) associated with patients having COPD GOLD III severity level and smoking history. Although HRV was the predominant virus detected the combined prevalence of Influenza A and B surpassing the rate of HRV. The high-level expression of well known inflammatory markers of AECOPD, TNF-α, IL-6 and IL-8 indicates a chronic severe illness. These markers play an important role and could be used as a marker for determining the severity of AECOPD.

Estima-se que a doença pulmonar obstrutiva crônica (DPOC) seja a terceira causa de mortalidade global em 2020. A exacerbação aguda DPOC (AECOPD) é um agravamento súbito dos sintomas da DPOC e pode ser devido a infecções por vírus/bactérias e poluição do ar. O aumento da expressão de marcadores inflamatórios em pacientes com AECOPD está associado à infecção viral. Este estudo teve como objetivo detectar diferentes vírus e analisar a expressão de vários marcadores inflamatórios associados a pacientes com AECOPD. Trezentos e quarenta e sete pacientes com diagnóstico de DPOC de acordo com os critérios GOLD foram incluídos neste estudo. Amostras de swab e sangue foram coletadas para detecção de vírus por RT-PCR e expressão de marcadores inflamatórios, respectivamente. Das amostras de esfregaço, 113 (32,6%) amostras foram positivas para detecção de vírus. Nestas, o HRV (39,8%) foi o vírus predominante detectado, seguido do FluB (27,4%) e do FluA (22,1%). A presença de VFC foi significativamente maior (p = 0,044) entre os demais vírus detectados. Quando comparados a controles saudáveis, os níveis de expressão de TNF-α, IL-6 e IL-8 foram significativamente maiores (p <0,05) em pacientes com vírus positivo. A IL-6 e a IL-8 foram as próximas predominantemente expressas em marcadores entre as amostras. A maior taxa de expressão de IL-8 foi significativamente (p <0,05) associada a pacientes com grau de gravidade GOLD III da DPOC e história de tabagismo. Embora o HRV tenha sido o vírus predominante, a prevalência combinada de Influenza A e B ultrapassou a taxa de HRV. O alto nível de expressão de marcadores inflamatórios bem conhecidos de AECOPD, TNF-α, IL-6 e IL-8 indica uma doença crônica grave. Esses marcadores desempenham um papel importante e podem ser usados como um marcador para determinar a gravidade da AECOPD.

Association between household solid fuel use and tuberculosis: cross-sectional data from the Mongolian National Tuberculosis Prevalence Survey

BACKGROUND@#Tuberculosis (TB) and indoor air pollution (IAP) are equally critical public health issues in the developing world. Mongolia is experiencing the double burden of TB and IAP due to solid fuel combustion. However, no study has assessed the relationship between household solid fuel use and TB in Mongolia. The present study aimed to assess the association between household solid fuel use and TB based on data from the Mongolian National Tuberculosis Prevalence Survey (MNTP Survey).@*METHOD@#The MNTP Survey was a nationally representative population-based cross-sectional survey targeting households in Mongolia from 2014 to 2015, with the aim of evaluating the prevalence of TB. The survey adopted a multistage cluster sampling design in accordance with the World Health Organization prevalence survey guidelines. Clusters with at least 500 residents were selected by random sampling. A sample size of 98 clusters with 54,100 participants was estimated to be required for the survey, and 41,450 participants were included in the final analysis of the present study. A structured questionnaire was used to collect information on environmental and individual factors related to TB. Physical examination, chest X-ray, and sputum examinations were also performed to diagnose TB.@*RESULTS@#The use of solid fuels for heating (adjusted odds ratio (aOR): 1.5; 95% confidence interval (CI): 1.1-2.1), male gender (aOR: 2.2; 95% CI: 1.6-3.2), divorced or widowed (aOR: 2.6; 95% CI: 1.7-3.8), daily smoker (aOR: 1.8; 95% CI: 1.3-2.5), contact with an active TB case (aOR: 1.7; 95% CI: 1.2-2.3), being underweight (aOR: 3.7; 95% CI: 2.4-5.7), and previous history of TB (aOR: 4.3; 95% CI: 3.0-6.1) were significantly associated with bacteriologically confirmed TB after adjusting for confounding variables.@*CONCLUSION@#The use of solid fuels for heating was significantly associated with active TB in Mongolian adults. Increased public awareness is needed on the use of household solid fuels, a source of IAP.

Combined Effects of A Body Shape Index and Serum C-reactive Protein on Ischemic Stroke Incidence among Mongolians in China / 生物医学与环境科学（英文）

OBJECTIVE@#We aimed to evaluate the combined effects of a high body shape index (ABSI) and a high serum C-reactive protein (CRP) level on the incidence of ischemic stroke in a Mongolian population in China.@*METHODS@#A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios (HRs) and 95% confidence intervals (CIs) for ischemic stroke among all groups.@*RESULTS@#The multivariate adjusted HRs (95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46 (0.89-2.39) and 1.63 (0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs (95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04 (0.46-2.35), 1.06 (0.58-1.95) and 2.52 (1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant.@*CONCLUSION@#We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.

Psychological Distress among Adolescents in Laos, Mongolia, Nepal, and Sri Lanka

PURPOSE: The purpose of this study was to explore psychological distress and examine the relationship between this distress and individual, family, and school factors among adolescents in four low- and middle-income countries (LAMICs) in Asia (i.e., Laos, Mongolia, Nepal, and Sri Lanka). METHODS: A total of 4,098 adolescents attending public schools in the four LAMICs were surveyed as part of the Healthy School Development Project, which aimed to develop school capacity for improving (1) health among all school members and (2) the school environment through tailored school health programs. Psychological distress, family factors (i.e., parental understanding and monitoring, and parental tobacco and alcohol use), and school factors (i.e., having close friends, not bullied, school attendance, and health education) were assessed using self-report questionnaires. Data were collected from September to November in 2012 and 2013. Data analysis comprised descriptive statistics, Chi-squared testing, and logistic regression. RESULTS: Over half of the participants were women (53.2%–64.1%), and 33.7% (in Sri Lanka) to 53.8% (in Laos) were aged older than 15 years. Approximately 32.9% reported the presence of psychological distress; moreover, 7.9%–13.2% reported suicidal ideation. Parental monitoring and being bullied were associated with psychological distress in all four countries. CONCLUSION: One-third of adolescents experience psychological distress across these four LAMICs, which poses a substantial public health issue. Adolescents can benefit from family and school-based approaches for screening, ameliorating, and preventing psychological distress.

Applying a mixed methods design for needs assessment of an international fellowship training program for Mongolian health professions / 한국의학교육

PURPOSE: Continuing professional development is essential for improving health care services, especially in developing countries. Most of the training programs in Mongolia were not based on a targeted needs assessment. Therefore, we aimed to apply a mixed methods design to assess the training needs of Mongolian health professions. METHODS: We conducted a needs assessment using a convergent parallel mixed methods design in two steps. The survey and interview questions were developed to identify priority areas, targeted trainees, and effective training methods. A survey on 60 respondents, 15 individual interviews, and a focus group interview with 14 participants were conducted in the first step. In the second step, 12 representatives of key stakeholders were invited to a second focus group interview. RESULTS: Current health policy areas, areas related to future national plans, and areas not currently receiving governmental or international support were suggested as the main priorities. The stakeholder suggested that trainees should be selected based on their professional experience and language level, as well as each hospital’s needs. Building teams including various professions, such as nurses, technicians, and biomedical engineers, was recommended as a way to exchange ideas with each other and to build teamwork for future collaboration. CONCLUSION: Medical training needs are dynamic and complex; therefore, a deep understanding of the context and setting is necessary. In this study, we assessed the targeted training needs of Mongolian health professions through a mixed methods design, which could be an effective way to conduct needs assessments for training programs.

Validation of the China-PAR Equations for Cardio-cerebrovascular Risk Prediction in the Inner Mongolian Population / 生物医学与环境科学（英文）

The objective of this study was to evaluate the usefulness of the China-PAR equations in predicting the 10-year risk of cardiovascular disease (CVD) in the Inner Mongolians population. A population-based, prospective cohort of 2,589 Mongolians were followed up from 2003 to 2012. Participants were categorized into 4 subgroups according to their 10-year CVD risks calculated using the China-PAR equations: < 5%, 5%-9.9%, 10%-19.9%, and ⪖ 20%. The China-PAR equations discriminated well with good C statistics (range, 0.76-0.86). The adjusted hazard ratios for CVD showed an increasing trend among the 4 subgroups (P for trend < 0.01). However, the China-PAR equations underestimated the 10-year CVD risk in Mongolians, and the calibration was unsatisfactory (Hosmer-Lemeshow χ2 = 19.98, P < 0.01 for men, χ2 = 46.58, P < 0.001 for women). The performance of the China-PAR equations warrants further validation in other ethnic groups in China.

Comparison of body image perception, nutrition knowledge, dietary attitudes, and dietary habits between Korean and Mongolian college students

BACKGROUND/OBJECTIVES: College students are in transition from adolescence to adulthood, and it has been reported that they show poor dietary habits. This study was conducted to compare body image perception, nutrition knowledge, dietary attitudes, dietary habits, and health-related lifestyles between Korean college students (KCS) and Mongolian college students (MCS). SUBJECTS/METHODS: Subjects were 314 KCS and 280 MCS. The data includes results of self-administered questionnaires; statistical analysis was performed using the SPSS 23.0 program. RESULTS: With regards to body image perception, KCS perceived themselves to be fatter on current body image than ideal body image compared to MCS; 64.0% of KCS and 34.6% of MCS desired to be thinner. Total score of nutrition knowledge in KCS (17.0) was significantly higher compared to MCS (8.4) (P < 0.001), but total score of dietary attitudes in KCS (27.0) was significantly lower compared to MCS (31.2) (P < 0.001). Nutrition knowledge had a significantly positive correlation with dietary attitudes in MCS (P < 0.01). Meal consumption among male and female subjects was 2 and 3 times, respectively, in order in KCS, and 3 and 2 times, respectively, in order in MCS (P < 0.001). Rate of skipping breakfast in both genders was significantly higher in KCS than in MCS (male: P < 0.05, female: P < 0.001). In health-related lifestyles, KCS had a significantly higher rate in frequency of alcohol drinking (P < 0.001), exercise (P < 0.01), and mobile phone usage (P < 0.001), compared to MCS. CONCLUSIONS: This study suggests that development of nutrition education program which is effective and proper is required to improve healthy dietary habits among college students of both countries. Essential contents should include acquirement of nutrition knowledge and a motivation for its application to actual life for KCS, and improvement of healthy dietary habits for MCS.

Perioperative gabapentin as a component of multimodal analgesia for postoperative pain after total knee arthroplasty

BACKGROUND: Total knee arthroplasty (TKA) causes considerable postoperative pain. This study investigated the analgesic effects of gabapentin on postoperative pain in patients undergoing unilateral TKA in Mongolia. METHODS: The study randomly assigned 95 patients with American Society of Anesthesiologists physical status class 1–3 scheduled for unilateral TKA into two groups. The treatment group (n = 49) was given gabapentin 600 mg 2 h preoperatively and gabapentin 300 mg in the evening for 3 days postoperatively. The control group (n = 46) was given identical looking placebo capsules. Pain using a visual analogue scale (VAS) and postoperative nausea and vomiting were assessed every hour postoperatively for 6 h and then every 3 h for the next 72 h. The total consumption of fentanyl in both groups was recorded at 24 and 48 h postoperatively. RESULTS: The very low VAS scores in both groups did not differ significantly. Patients in the treatment group used less fentanyl on the second day (P = 0.001). The incidence of nausea and vomiting were similar in both groups, except for the low incidence of nausea in the treatment group in the first 6 h postoperatively. CONCLUSIONS: Perioperative gabapentin may be a component of a multimodal analgesia method because it reduced fentanyl consumption in patients who underwent TKA. However, the overall low VAS scores do not allow any firm conclusions.

Stroke Epidemiology in South, East, and South-East Asia: A Review / 대한뇌졸중학회지

Asia, which holds 60% of the world’s population, comprises some developing countries which are in economic transition. This paper reviews the epidemiology of stroke in South, East and South-East Asia. Data on the epidemiology of stroke in South, East, and South-East Asia were derived from the Global Burden of Disease study (mortality, disability-adjusted life-years [DALYs] lost because of stroke), World Health Organization (vascular risk factors in the community), and publications in PubMed (incidence, prevalence, subtypes, vascular risk factors among hospitalized stroke patients). Age- and sex-standardized mortality is the lowest in Japan, and highest in Mongolia. Community-based incidence data of only a few countries are available, with the lowest rates being observed in Malaysia, and the highest in Japan and Taiwan. The availability of prevalence data is higher than incidence data, but different study methods were used for case-finding, with different age bands. For DALYs, Japan has the lowest rates, and Mongolia the highest. For community, a high prevalence of hypertension is seen in Mongolia and Pakistan; diabetes mellitus in Papua New Guinea, Pakistan, and Mongolia; hypercholesterolemia in Japan, Singapore, and Brunei; inactivity in Malaysia; obesity in Brunei, Papua New Guinea, and Mongolia; tobacco smoking in Indonesia. Hypertension is the most frequent risk factor, followed by diabetes mellitus and smoking. Ischemic stroke occurs more frequently than hemorrhagic stroke, and subarachnoid hemorrhages are uncommon. There are variations in the stroke epidemiology between countries in South, East, and South-East Asia. Further research on stroke burden is required.

Acute hepatitis A, B and C but not D is still prevalent in Mongolia: a time trend analysis

BACKGROUND/AIMS: Mongolia has one of the highest hepatitis A, C, B and D infection incidences worldwide. We sought to investigate changes in the proportion of acute viral hepatitis types in Mongolia over the last decade. METHODS: The cohort comprised 546 consecutive patients clinically diagnosed with acute viral hepatitis from January 2012 to December 2014 in Ulaanbaatar Hospital, Mongolia. A time trend analysis investigating the change in proportion of acute hepatitis A virus, hepatitis C virus (HCV), hepatitis B virus (HBV) and hepatitis delta virus (HDV) infection among the cohort with respect to a previous published study was undertaken. RESULTS: Acute hepatitis A, B and C was diagnosed in 50.9%, 26.2% and 6.0% of the cohort. Notably, 16.8% of the cohort had a dual infection. The etiologies of acute viral hepatitis were varied by age groups. The most common cause of acute viral hepatitis among 2-19 year olds was hepatitis A, HBV and superinfection with HDV among 20-40 year olds, and HCV among 40-49 year olds. Patients with more than one hepatitis virus infection were significantly older, more likely to be male and had a higher prevalence of all risk factors for disease acquisition. These patients also had more severe liver disease at presentation compared to those with mono-infection. CONCLUSIONS: Acute viral hepatitis is still prevalent in Mongolia. Thus, the need for proper infection control is increasing in this country.

Total phenolic, flavonoid, alkaloid and iridoid content and preventive effect of Lider-7-tang on lipopolysaccharide-induced acute lung injury in rats

Lider-7-tang, a medicine used for the treatment of respiratory diseases especially pneumonia and fever in Mongolian Traditional Medicine, was selected for this phytochemical and pharmacological study. The objectives of the study were to determine total biological active substances and analyze the effects of Lider-7-tang treatment in rats with acute lung injury (ALI). Quantitative determination of the total active constituents (phenolic, flavonoid, iridoid and alkaloid) of the methanol extract of Lider-7-tang was performed using Folin-Ciocalteu reagent, aluminum chloride reagent, Trim-Hill reagent, and Bromocresol green reagent, respectively. A total of fifty 8-10-week-old male Wistar rats (200-240 g) were randomized into three groups: control group, lipopolysaccharide (LPS) group (7.5 mg/kg) and LPS+Lider-7 group (90 mg/kg Lider-7-tang before LPS administration). The total content of alkaloids was 0.2±0.043%, total phenols 7.8±0.67%, flavonoids 3.12±0.206%, and iridoids 0.308±0.0095%. This study also evaluated the effects of Lider-7 on levels of inflammatory mediators by observing histopathological features associated with LPS-induced ALI. The rats pretreated with Lider-7 had significantly lower levels of IL-6 (at 3 and 6 h), and TNF-α (at 3, 6, 9, and 12 h). The current study showed that Lider-7 exerted a preventive effect against LPS-induced ALI, which appeared to be mediated by inhibiting the release of pro-inflammatory cytokines.

Mental Health and Health Risk Behaviors of Multicultural Adolescents according to Their Mothers' Native Country: Using Data from the 11th (2015) Korea Youth Risk Behavior Web-Based Survey 2015

PURPOSE: The purpose of this study was to analyze the mental health and health risk behaviors of multicultural adolescents according to their mothers' native country. METHODS: For this study raw data from the 11th Youth Health Behavior Online Survey (2015) was examined. Mental health and health risk behaviors for 62,985 adolescents were analyzed according to their mothers' native country. Collected data were analyzed with the SPSS program using descriptive statistics and logistic regression analysis, to which the complex sample design was applied. RESULTS: The odds ratio of depression in multicultural adolescents compared to Korean adolescents was 44.92 (CI: 5.77-349.59) for adolescents whose mothers came from Cambodia and 3.00 (CI: 1.57-5.76) for adolescents whose mothers came from North Korea. The odds ratio of attempted suicide was 14.73 (CI: 3.09-70.22) for adolescents whose mothers came from Cambodia and 8.63 (CI: 3.45-21.62) for adolescents whose mothers came from North Korea. The odds ratio of problematic drinking in multicultural adolescents was 7.47 (CI: 1.71-32.67) for adolescents whose mothers came from Mongolia. CONCLUSION: Findings indicate that when planning a health promotion program for adolescents from multicultural families, a customized approach should be sought taking into account the characteristics of mothers' native country.

Chewing Lice of Swan Geese (Anser cygnoides): New Host-Parasite Associations

Chewing lice (Phthiraptera) that parasitize the globally threatened swan goose Anser cygnoides have been long recognized since the early 19th century, but those records were probably biased towards sampling of captive or domestic geese due to the small population size and limited distribution of its wild hosts. To better understand the lice species parasitizing swan geese that are endemic to East Asia, we collected chewing lice from 14 wild geese caught at 3 lakes in northeastern Mongolia. The lice were morphologically identified as 16 Trinoton anserinum (Fabricius, 1805), 11 Ornithobius domesticus Arnold, 2005, and 1 Anaticola anseris (Linnaeus, 1758). These species are known from other geese and swans, but all of them were new to the swan goose. This result also indicates no overlap in lice species between older records and our findings from wild birds. Thus, ectoparasites collected from domestic or captive animals may provide biased information on the occurrence, prevalence, host selection, and host-ectoparasite interactions from those on wild hosts.

Alcohol Drinking, Dyslipidemia, and Diabetes: A Population-based Prospective Cohort Study among Inner Mongolians in China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>No previous studies have evaluated the association between dyslipidemia, alcohol drinking, and diabetes in an Inner Mongolian population. We aimed to evaluate the co-effects of drinking and dyslipidemia on diabetes incidence in this population.</p><p><b>METHODS</b>The present study was based on 1880 participants from a population-based prospective cohort study among Inner Mongolians living in China. Participants were classified into four subgroups according to their drinking status and dyslipidemia. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curves were used to evaluate the association between alcohol drinking, dyslipidemia, and diabetes.</p><p><b>RESULTS</b>During the follow-up period, 203 participants were found to have developed diabetes. The multivariable-adjusted odds ratios (95% confidence interval) for the incidence of non-dyslipidemia/drinkers, dyslipidemia/non-drinkers, and dyslipidemia/drinkers in diabetic patients were 1.40 (0.82-2.37), 1.73 (1.17-2.55), and 2.31 (1.38-3.87), respectively, when compared with non-dyslipidemia/non-drinkers. The area under the ROC curve for a model containing dyslipidemia and drinking status along with conventional factors (AUC=0.746) was significantly (P=0.003) larger than the one containing only conventional factors (AUC=0.711).</p><p><b>CONCLUSION</b>The present study showed that dyslipidemia was an independent risk factor for diabetes, and that drinkers with dyslipidemia had the highest risk of diabetes in the Mongolian population. These findings suggest that dyslipidemia and drinking status may be valuable in predicting diabetes incidence.</p>

Application of Diagnostic Microarray Technique in Subtyping and Pathotyping of Avian Influenza Viruses Isolated in Mongolia

Asian-lineage H5 highly pathogenic avian influenza (HPAI) viruses have caused continuous outbreaks in poultry and wild birds. Development of rapid and accurate diagnostic methods is needed for preventing further spread of the virus and reducing the time required for eradication of the virus. We developed a low-density microarray for the rapid detection and identification of avian influenza virus subtypes H5, H7, and H9 and their pathotypes in a previous study. In the present study, we evaluated previously developed diagnostic microarray using avian influenza viruses isolated in Mongolia, including H5 HPAI viruses. All H5 HPAI viruses isolated in Mongolia were shown as H5-specific and highly pathogenic pattern in the microarray. H2, H3 and H12 viruses isolated in Mongolia used in this study did not show any H5, H7 and H9 patterns. These results indicated that this diagnostic microarray has enormous potential for the rapid subtyping and pathotyping of influenza viruses, including viruses isolated in Mongolia.

Combined effects of both cardiovascular disease family history and smoking on the incidence of ischemic stroke / 中华流行病学杂志

<p><b>OBJECTIVE</b>To investigate the cumulative effect regarding the family history of cardiovascular disease and smoking on ischemic stroke events in population with Mongolian ethnicity.</p><p><b>METHODS</b>Based on data gathered from the baseline investigation, a 10-year prospective cohort follow-up project was conducted among 2 589 participants with Mongolian ethnicity. Ischemic stroke events were defined as the outcomes of the study. All the 2 589 participants were categorized into four subgroups: without family history of cardiovascular disease/nonsmokers, without family history of cardiovascular disease/smokers, with family history of cardiovascular disease/nonsmokers and with family history of cardiovascular disease/smokers, according to family history of cardiovascular disease and smoking status. Cumlative incidence rates of events among the four subgroups was described with Kaplan-Meier curves. Cox proportional hazards model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (95%CI) of ischemic stroke events among the four subgroups.</p><p><b>RESULTS</b>Data from the Kaplan-Meier curves showed that the cumulative incidence rates of ischemic stroke were 1.17% (15/1 278), 3.83% (37/967), 5.70% (9/158) and 8.33% (15/180) for the groups of no family history of cardiovascular disease/nonsmokers, no family history of cardiovascular disease/smokers, with family history of cardiovascular disease/nonsmokers and with family history of cardiovascular disease/smokers, respectively. By cox proportional hazards model, after adjusting for age, male, drinking status, systolic and diastolic blood pressure, body mass index, fasting glucose, total cholesterol, triglycerides, LDL cholesterol factors, the HRs (95% CI) of ischemic stroke were 2.26 (1.19-4.28) and 2.45 (1.13-5.33) in the no family history of cardiovascular disease/smokers group, with family history of cardiovascular disease/smokers group when compared to the no family history of cardiovascular disease/nonsmokers group, respectively. The risk of ischemic stroke appeared the highest in the group with family history of cardiovascular disease/smokers (all P<0.05).</p><p><b>CONCLUSION</b>Smoking may increase the risk of ischemic stroke events among the population with family history of cardiovascular disease.</p>
