Objective: To understand the current situation and demand school health education in five areas across China, and to provide theoretical support for further revision and improvement on school health education. Methods: Stratified multi stage cluster sampling was adopted. A total of 4 052 students were selected from five areas across China [Urumqi( n =1 295), Haikou City( n =448), Shijiazhuang City( n =788), Chengdu City( n =728), Suzhou City( n =793)]. Online questionnaire survey was conducted by questionnair star. Results: About 89.98% of the students used the use of uniform teaching materials, and 63.50% attended the health education classes once a week. The main sources of health knowledge, the use of uniform teaching materials, class schedule and the difference of teachers in different regions and periods were statistically significant ( χ 2=54.98, 40.97, 590.08, 1 061.12；50.70, 47.68 , 356.09, 193.30, P <0.05). The main source of health knowledge was from school/teachers(92.47%). Most health education teachers were classroom teachers(30.03%). Content of health education that students were interested in varied by gender and grade ( χ 2=20.91, 35.90, P <0.05), but not by area ( P >0.05). Demand for health knowledge of students varied by area and grade ( χ 2=177.29, 32.37, P <0.05). Conclusion The status quo of health education in schools is good. Further attention should be paid to cultivate high quality health education teachers and provide targeted health education activities according to students demand, and ultimately improving health literacy among students.

OBJECTIVETo investigate the relationship between homocysteine (Hcy), von willebrand factor (vWF), soluble intercellular adhesion molecule-1 (sICAM-1) and the risk of cardio-cerebrovascular events among Inner Mongolians.

METHODSA survey was conducted among 2 589 Inner Mongolians from May 2002 to June 2003, and they were followed up for about ten years. The 182 individuals who developed cardio-cerebrovascular events in the cohort were defined as cases and those whose age, gender and residence 1:1 matched to cases were selected from the individuals who did not developed cardio-cerebrovascular events as controls. Then, a nested case-control study was used to analyze the relationship between Hcy, vWF and sICAM-1 and risk of cardio-cerebrovascular events. Conditonallogistic regression analysis was used to calculate OR values and 95% CI.

RESULTSThe cases had a higher baseline blood pressure, higher prevalence of hypertension and family history of hypertension compared to controls (all P values < 0.05), however, there were no significantly different between TC, TG, LDL-C, HDL-C, FBG, smoking and drinking rates (all P values > 0.05). The M (P(25)-P(75)) of Hcy were 10.68 (7.84-14.98) and 10.02 (6.64-13.94) µmol/L, vWFs were 10.88 (8.14-14.58) and 10.42 (7.97-13.50) mg/L, sICAM-1 were 336.48 (260.68-409.87) and 335.12 (269.87-409.87) ng/ml. They were not significantly different between the two groups (Z values were 0.89, 0.94 and 0.29, respectively, all P values >0.05). After adjustment for the family history of hypertension, hypertension, TC, FPG, BMI, smoking and drinking rate, the conditional logistic regression showed that OR (95% CI) of risk of cardio-cerebrovascular events were 1.00 (0.52-1.93), 2.37 (1.25-4.49), and 0.81 (0.45-1.47) for the participants with increased Hcy, vWF, and sICAM-1, compared with those with normal Hcy, vWF, and sICAM-1, respectively.

CONCLUSIONIn the Inner Mongolians, increased vWF at baseline may increase the risk of cardio-cerebrovascular events, and increased Hcy and sICAM-1 were not significantly associated with the risk of cardio-cerebrovascular events.

Objective To investigate the relationship between interleukin-6(IL-6),endothelin-1 (ET-1),E-selectin and the risk of cardio-cerebrovascular events. Methods Based on a cohort study in which 2 589 Mongolians had been followed up for 10 years,a nested case-control study was carried out to analyze the relationship between IL-6, ET-1, E-selectin and the risk of cardio-cerebrovascular events. Logistic regression analysis was used to calculate the odds ratio(OR) and 95%confidence intervals(95%CI). Results The average level of IL-6(7.66 vs. 8.77 pg/ml), ET-1(0.74 vs. 0.75 pg/ml) and E-selectin (17.96 vs. 18.32 ng/ml) were not significantly different between the case and the control groups(P>0.05). Data from the logistic regression analysis showed that IL-6,ET-1 and E-selectin were not significantly associated with the risk of cardio-cerebrovascular events. The multivariable adjusted ORs(95%CI)on the risk of cardio-cerebrovascular events were 0.69 (0.41-1.16),1.10 (0.66-1.85) and 1.19(0.71-2.00) for the participants with IL-6>23.91 pg/ml ,ET-1>1.33 pg/ml and E-selectin>24.43 ng/ml,respectively,compared with those having IL-6≤23.91 pg/ml ,ET-1≤1.33 pg/ml or E-selectin≤24.43 ng/ml. Conclusion Data from our study indicated that the levels of IL-6,ET-1 and E-selectin at baseline were not significantly associated with the risk of cardio-cerebrovascular events in people from Inner Mongolia.
