[Prevalence and influential factors of stroke in Jiangxi Province in 2014].

Objective: To discuss the prevalence and influential factors of stroke among population in Jiangxi Province. Methods: Four cities in urban areas and four counties in rural areas were selected firstly, in which two districts or townships were selected; and then three communities or villages were chosen from each district and township, respectively, using the simple random sampling (SRS) method. Finally 15 269 subjects aging 15 years old or above, living in Jiangxi Province ≥6 months were randomly selected to participate in this survey from November 2013 to August 2014. Information of population characteristics, life behavior way, individual disease history were collected through questionnaire survey, and height, weight, waist circumference, blood pressure, body fat rate, visceral fat index and so on were measured by instruments. Risk factors of stroke prevalence were analyzed by the unconditioned logistic regression analysis. Results: A total of 15 269 participants (6 267 males) from 15 364 eligible participants were included in the statistical analysis. Out of which, 7 793 participants came from urban areas, and their average age was (53.04±17.91) years old. In this study, 226 stroke patients (117 males) were found among15 269 participants, including 122 urban participants and 104 rural participants, whose average age was (67.76±9.74) years old. The prevalence of stroke was 1 480.12/100 000 in 2014, which was separately 1 866.92/100 000 and 1 210.84/100 000 among males and females. The prevalence of people aging (45-49) years old was 413.79/100 000 (6/1 450) , while which among people aging 75 years old and above was 3 311.62/100 000 (61/1 842) . The prevalence of stroke among residents in Jiangxi presented an uprising tendency with age increasing (linear-by-linear association χ(2)=62.23, P<0.01). The research showed that when other influencing factors including gender, BMI, waist circumference, pulse-pressure difference, VAI, and sleeping time in non-working days were controlled, hypertensive patients had a higher risk of stroke than people without hypertension (OR=6.88, 95%CI: 4.90-9.67), drinkers had a higher risk of stroke than non-drinkers (OR=1.56, 95%CI: 1.17-2.08), compared with people <65 years old, people aged 65-74 years old and ≥75 years old had a higher risk of stroke, the value of OR (95%CI) were 1.88 (1.36-2.59) and 1.97 (1.39-2.80), respectively, compared with people with normal body fat percentage, people whose body fat percentage on high side and people who with high body fat percentage had a higher risk of stroke, the value of OR (95%CI) were 1.71 (1.18-2.48) and 1.74 (1.18-2.56), respectively, people with sleep time >8 h had a higher risk of stroke than those with sleep time of 6-8 h. Conclusion: There was a high stroke prevalence among residents in Jiangxi province. Hypertension, drinking, age, BFP and sleep duration were associated with stroke prevalence. Corresponding measures for high-risk population and risk factors should be strengthened to prevent and control the stroke.目的： 探讨江西省脑卒中患病率并分析其相关因素。 方法： 于2013年11月至2014年7月，采用多阶段分层随机抽样方法在江西省抽取8个县/区，在每个县/区通过简单随机抽样法抽取2个乡镇/街道，每个乡镇/街道抽取3个村/居委会，选取年龄≥15岁且在该地区居住≥6个月居民作为调查对象，最终纳入调查对象15 269名。通过问卷调查收集调查对象的人口学特征、生活行为方式、个人疾病史等信息。测量身高、体重、腰围、血压，并计算身体脂肪率（BFP）、内脏脂肪指数（VAI）。采用logistic回归分析模型进行脑卒中相关因素分析。 结果： 15 269名调查对象年龄为（53.04±17.91）岁，其中男性为6 267名，城市居民为7 793名。脑卒中患者226例，年龄为（67.76±9.74）岁，其中男性为117例。2014年江西省居民脑卒中患病率为1 480.12/10万，其中男性为1 866.92/10万，女性为1 210.84/10万。45~49岁江西省居民脑卒中患病率为413.79/10万（6/1 450），≥75岁患病率为3 311.62/10万（61/1 842），患病率随着年龄增加呈上升趋势（χ(2)=62.23，P<0.01）。调整性别、BMI、腰围、脉压、VAI和非工作日睡眠时间等因素的影响，与非高血压者相比，高血压患者患脑卒中的OR（95%CI）值为6.88（4.90~9.67）；与不饮酒者比较，饮酒者患脑卒中的OR（95%CI）值为1.56（1.17~2.08）；与<65岁年龄组相比，65~74和≥75岁年龄组居民患脑卒中的OR（95%CI）值分别为1.88（1.36~2.59）、1.97（1.39~2.80）；与BFP正常组比较，BFP偏高和高的居民患脑卒中的OR（95%CI）值分别为1.71（1.18~2.48）、1.74（1.18~2.56）；睡眠时间与脑卒中的发生存在关联，与睡眠6~8 h者相比，睡眠>8 h者患脑卒中的OR（95%CI）值为1.80（1.28~2.52）。 结论： 江西省脑卒中患病率较高，高血压、饮酒、年龄、BFP、睡眠时间为脑卒中患病率的相关因素，应针对重点人群和危险因素加强脑卒中发病的防控。.
