Objective To explore the prevalence and related factors of behavior problems among the high-grade primary school students (in Grade 4 to Grade 6) in Chongqing urban area. Methods By means of cross-sectional survey, a total of 3 137 high-grade primary school students in Chongqing urban area were investigated with Child Behavior Checklist (CBCL, version for parents) and self-designed basic information questionnaire. Results The relevance ratio of behavior problems was 27.26%. The univariate analysis revealed that type of school, grade, residential and family environment, and parental attitude toward children had effects on children’s behavior problems with significance difference (Plt;0.05). The stepwise regression revealed that grade, educational level of father, healthy conditions of parents, family structure, academic performance and parental attitude toward children were the independent and main influencing factors (Plt;0.05). Conclusion The relevance ratio of behavior problems among high-grade primary school students in Chongqing urban area is much higher, which is related to the following factors: family situation, parental attitude toward children, social and school environment. It indicates that the status of children’s mental heath is not optimistic in Chongqing urban area. Comprehensive measures combining family, school with psychologist should be taken to reduce the prevalence of behavioral problems.
Objective To study the composition, distribution, and influencing factors of acute hand injuries in daily l ife in the Beijing area by analyzing the cl inical data from patients with acute hand injuries. Methods Between April 1st 2005 to September 30th 2005, 2 575 patients with acute hand injuries in daily l ife from Beijing area were investigated by questionnaire.The epidemiological factors were analyzed, including gender, age, injury time, injury cause, accident place, injury mechanism, and location. Results The 2 575 patients injuried in daily l ife accounted for 49.2% of all. Most of them were young males, and the male to female ratio was 3.3 ∶ 1. Most of the patients were 21-30 years old. The most common accident place was resting place (43.3%), and next was outdoors (28.8%) and leisure place (20.0%). Accidental injury was the major injury cause, accounted for 51.0%, followed by injury after drinking (16.1%) and violence (15.5%). The major injury mechanism was cutting (52.23%), followed by coll ision (16.04%) and fall ing (15.18%). A total of 2 405 patients were right hander, and handedness affected the distribution of injured hands significantly. Open injuries accouonted for 70.7% of the patients, and the tissues in deep layer were involved in the injury in 54.4% of all. Conclusion Hand injury in daily l ife is a common problem, which has its own epidemiological features. More appropriate measures should be taken to decrease the incidence.
Objective To investigate the current prevalence of cerebral stroke and hypertension in Ganzi Tibetan state, so as to control stroke and hypertension in future. Methods A representative people sample of Kangding, Dege, Ganzi, Litang and Batang county was selected through randomized cluster sampling. Data of demographic characteristics, hypertension and stroke status were collected by face-to-face interview. Results 5 049 people were included, of which 48.6% were male, and 51.4% were female. The prevalence rate of hypertension and stroke were 23.4% and 1 894/100 000 respectively. The population with hypertension had high prevalence of stroke. The prevalence increased along with the age. Conclusions The prevalence of hypertension and stroke is high in Ganzi Tibetan state. The causes may be ascribed to special geography surroundings and life style. It is very important to pay more attention to prevent and control of hypertension and stroke in this area.
ObjectiveTo compare the risk factors of angina pectoris and atherosclerotic thrombotic cerebral infarction, and to study the possible risk factors of angina pectoris complicated with atherosclerotic thrombotic cerebral infarction (XNHB abbr. in Chinese) and provide the basis for the prevention of XNHB. MethodsClinical epidemiological cross-sectional survey methods were used. Information of angina pectoris patients, atherosclerotic thrombotic cerebral infarction patients and XNHB patients were collected. The statistical software SPSS 17.0 was used to analyze the single risk factors, and then logistic regression analysis was used to filter the independent risk factors of XNHB. Results1 002 cases of angina pectoris, 963 cases of atherosclerotic thormbotic cerebral infaction and 982 cases of XNHB were included. There were significant differences among the three diseases in the following index:age (P=0.000 0), gender (P < 0.000 1), resting lifestyle (P=0.000 0), body mass index (BMI) (P=0.000 0), diabetes (P=0.001 9), hypertension (P < 0.000 1), diabetes complicated with hypertension (P < 0.000 1), smoking (P < 0.000 1), alcohol consumption (P < 0.000 1), and the combination of more than 3 risk factors (P=0.000 0). Age (OR=1.690, 95%CI 1.420 to 2.012), hypertension (OR=1.558, 95%CI 1.312 to 1.850), abnormal BMI (OR=1.356, 95%CI 1.158 to 1.587) and resting lifestyle (OR=1.319, 95%CI 1.107 to 1.572) were shown as the independent risk factors of XNHB filtering by logistic multiple regression analysis. ConclusionThe elderly with hypertension, abnormal BMI or live a resting way of life are more likely to have XNHB, so positive control of risk factors should be needed.
