Prevalence of stroke and associated risk factors: a population based cross sectional study from northeast China

Abstract

ObjectivesEpidemiological studies aimed at stroke and its risk factors can help identify persons at higher risk and therefore promote stroke prevention strategies. We aimed to explore the current prevalence of stroke and its associated risk factors in northeast China.DesignPopulation based cross sectional study.SettingData were collected using a structured precoded questionnaire designed by the Stroke Screening and Prevention Programme of the National Health and Family Planning Commission of China, between January and March 2016.Participants4100 permanent residents, aged 40 years or older, who had lived in Dehui City of Jilin Province for more than 6 months volunteered to participate in the survey, with a response rate of 92.2%. For the purpose of the present analysis, 48 subjects were excluded due to missing values, giving a total of 4052 people included in this analysis.Main outcome measureThe questionnaire included demographic characteristics, stroke related behavioural factors, personal and family medical history of stroke, physical examination and laboratory testing.ResultsThe overall prevalence of stroke in Jilin Province was 7.2% (95% CI 6.3% to 8.2%). Of all stroke cases, 91.7% (95% CI 87.4% to 94.6%) were ischaemic stroke and 8.3% (95% CI 5.4% to 12.6%) were haemorrhagic stroke. The prevalence rates of dyslipidaemia, smoking and hypertension were ranked as the top three cerebrovascular risk factors and were 62.1%, 61.8% and 57.3%, respectively. We found that hypertension, dyslipidaemia and lack of exercise were associated with ischaemic stroke. However, only hypertension (OR=4.064, 95% CI 1.358 to 12.160) was significantly associated with haemorrhagic stroke.ConclusionsThe prevalence of stroke, especially ischaemic stroke, and associated cerebrovascular risk factors among adults aged 40 years or older in northeast China were high. A higher regional prevalence of hypertension, dyslipidaemia and lack of exercise may be responsible.

Management practice, and treatment outcome and its associated factors among hospitalized stroke patient at Ambo University Referral Hospital, Ethiopia: an Institutional Based Cross Sectional Study

“…The finding of this study revealed that ischemic type of stroke was predominated in 80.1% of total stroke victims. This is in line with various studies conducted at different part of world; 55.6% (8), 56.7% (9), 65.8% (10), 69.4% (14), 85.7% (12) and 91.7% (18). Contrastingly, hemorrhagic stroke was the most common in studies conducted at St. Paul's Teaching Hospital (61.3%) (13), Jimma (64.3%) (19) and Rwanda (65%) (20).…”

“…This may be probably due to small sample size in our study. It is in accordance with other hospital based study done at University of Gondar Teaching Hospital (8) and population based cross sectional study in China (18). In contrast to this, a study done in Rwanda showed that initial presentation with severe stroke was the major cause of death among stroke patients (20).…”

Prevalence of stroke and stroke related risk factors: a population based cross sectional survey in southwestern China

“…These findings were consistent with those of previous studies on stroke prevalence in China [1,20]. The prevalence of stroke in Sichuan was higher than the nationwide findings [1,6], but was lower than in northeast China [20]. The prevalence of stroke increased with age, and this was consistent with other studies [25].…”

“…We have also identified a high prevalence of stroke and stoke related risk factors among adults aged ≥40 years, and found that age, male, diabetes, hypertension, dyslipidemia, lack of exercise, overweight were associated with a high prevalence of stroke and ischemic stroke. These findings were consistent with those of previous studies on stroke prevalence in China [1,20]. The prevalence of stroke in Sichuan was higher than the nationwide findings [1,6], but was lower than in northeast China [20].…”

“…Body mass index (BMI) was calculated as weight (kg) divided by height squared (m 2 ), and overweight or obesity was defined as BMI ≥26 kg/m 2 [19]. Physical inactivity was defined as physical exercise < 3 times a week for < 30 min each time, and this included industrial and agricultural labour [20]. A family history of stroke was restricted to immediate family members.…”
