ABSTRACT
BACKGROUND@#Understanding the changing profiles of cardiovascular disease (CVD) and modifiable risk factors is essential for CVD prevention and control. We aimed to report the comprehensive trends in CVD and risk factors in China from 1990 to 2019.@*METHODS@#Data on the incidence, death, and disability-adjusted life years (DALYs) of total CVD and its 11 subtypes for China were obtained from the Global Burden of Disease Study 2019. The CVD burden attributable to 12 risk factors was also retrieved. A secondary analysis was conducted to summarize the leading causes of CVD burden and attributable risk factors.@*RESULTS@#From 1990 to 2019, the number of CVD incidence, death, and DALYs considerably increased by 132.8%, 89.1%, and 52.6%, respectively. Stroke, ischemic heart disease, and hypertensive heart disease accounted for over 95.0% of CVD deaths in 2019 and remained the top three causes during the past 30 years. Between 1990 and 2019, the age-standardized rate of stroke decreased significantly (percentage of decreased incidence: -9.3%; death: -39.8%; DALYs: -41.6%), while the rate of ischemic heart disease increased (percentage of increased incidence: 11.5%; death: 17.6%; DALYs: 2.2%). High systolic blood pressure, unhealthy diet, tobacco, and air pollution continued to be the major contributors to CVD deaths and DALYs (attributing to over 70% of the CVD burden), and the high body mass index (BMI)-associated CVD burden had the largest increase between 1990 and 2019.@*CONCLUSIONS@#The significant increases in the number of CVD incident cases, deaths, and DALYs suggest that the CVD burden is still a concern. Intensified strategies and policies are needed to maintain promising progress in stroke and to reduce the escalating burden of ischemic heart disease. The CVD burden attributable to risk factors has not yet made adequate achievements; even worse, high BMI has contributed to the increasing CVD burden.

Objective@#This study aimed to explore the association between malnutrition and the level of blood pressure (BP) as well as elevated BP (EBP) in Han students aged 7 to 18 years in China.@*Methods@#170 037 subjects with normal nutritional status and malnutrition were enrolled in this study from 2014 Chinese National Surveys on Students' Constitution and Health with a multi-stage stratified cluster random sampling framework covering 31 provinces, autonomous regions and municipalities after the exclusion of 44 317 overweight and obese students. According to the standard of "Screening Standard for Malnutrition of School-age Children and Adolescents" (WS/T456-2014), the nutritional status of children were classified into two categories, normal nutritional status and malnutrition containing stunting, mild wasting and moderate severe wasting. The level of BP and prevalence of EBP were compared between students with normal nutritional status and malnutrition. The multivariate logistic regression model was used to analyze the association between malnutrition and EBP.@*Results@#The levels of systolic BP (SBP) and diastolic BP (DBP) in Chinese Han students aged 7-18 years who were non-overweight and non-obesity status were (103.4±12.3) and (64.7±9.5) mmHg (1 mmHg=0.133 kPa), respectively. The prevalence of EBP, systolic EBP and diastolic EBP in Chinese Han malnourished students (N=21 012) were 3.1% (n=649), 1.5% (n=324) and 2.1% (n=445), respectively, which was significantly lower than those (N=148 320) with normal nutritional status (4.5% (n=6 707), 2.6% (n=3 872) and 2.7% (n=3 959)), and the corresponding differences were statistically significant (P<0.05). The OR (95%CI) between malnutrition and EBP was 0.68 (0.62-0.73), which were 0.65 (0.58-0.72) and 0.68 (0.60-0.77) for boys and girls. The OR (95%CI) between EBP and stunting as well as mild wasting and moderate severe wasting were 0.69 (0.62-0.77), 0.63 (0.55-0.72) and 0.79 (0.60-1.05), respectively.@*Conclusion@#The level of BP and prevalence of EBP in Chinese Han students with malnutrition were lower than those with normal nutritional status. The negative correlation existed between malnutrition and EBP in Chinese Han students aged 7 to 18 years.
ABSTRACT
Objective@#To investigate the prevalence and related factors of dyslipidemia among children and adolescents aged 6-17 years in 7 provinces in China.@*Methods@#Using the method of stratified cluster random sampling, 93 primary and secondary schools were selected from Guangdong, Hunan, Liaoning provinces, Shanghai, Chongqing, Tianjin municipalities and Ningxia Hui Autonomous Region in China, 2012. A total of 16 434 students aged 6-17 years old with completed physical and lipid profiles parameters were selected into this study from above 93 primary and secondary schools. Dyslipidemia was determined by the definition of Expert Advice on Prevention and Treatment of Dyslipidemia in Children and Adolescents in 2009. Logistic regression model was used to explore the factors related to dyslipidemia.@*Results@#The prevalence of elevated total cholesterol, elevated triglyceride, elevated low-density lipoprotein cholesterol, low high-density lipoprotein cholesterol, and dyslipidemia was 5.4% (887 cases), 15.7% (2 578 cases), 3.0% (492 cases), 13.5% (2 221 cases) and 28.5% (4 679 cases) among children and adolescents aged 6-17 years, respectively. Sugary drinks intake ≥once per week (OR=1.14; 95%CI: 1.05-1.24), sedentary time >10 hours per day (OR=1.14, 95%CI: 1.01-1.28), overweight (OR=1.50, 95%CI: 1.33-1.70), and obesity (OR=2.62, 95%CI: 2.31-2.96) were significantly associated with the prevalence of dyslipidemia.@*Conclusion@#The prevalence of dyslipidemia was high among children and adolescents aged 6-17 in 7 provinces in China, 2012. Sugary drinks intake ≥once per week, sedentary time >10 hours per day, overweight and obesity might be the risk factors of dyslipidemia among children and adolescents.
ABSTRACT
Objective@#To analyze the prevalence of physical fitness among Chinese Han students aged 13-18 years in 2014, and explore related influencing factors.@*Methods@#This study recruited 106 881 Han students aged 13-18 years who had taken physical fitness test from Chinese National Survey on Students' Constitution and Health in 2014. After the exclusion of 1 047 students without complete records of physical fitness test, 105 834 students were included in the final analysis. According to the National Student Physical Health Standard modified in 2014, seven indicators including body mass index, vital capacity, 50-m run, sit-and-reach, standing broad jump, pull-ups/curl-ups and endurance run were tested to calculate the total score of students' physical fitness. Students with score ≥60 were regarded as qualified students. Multivariate non-conditional logistic regression model was used to analyze influencing factors of physical fitness.@*Results@#Among Chinese Han students aged 13-18 years, the total score was 70.1±10.7 and the qualified rate was 83.9% (n=88 813). Boys (83.5% (44 197/52 910)) had a lower qualified rate of physical fitness than girls (84.3% (44 616/52 924)) (P<0.001), and 13-15 age group (86.5% (46 255/53 465)) was higher than the 16–18 age group (81.3% (42 558/52 369)) (P<0.001). Except for 16–18-year-old boys from central region, normal body mass index, eastern region, good socioeconomic status, enough PE class, exercise time ≥1 h/d, homework time ≥2 h/d, TV time <1 h/d were all related to high qualified rates of physical fitness (P<0.05).@*Conclusion@#Chinese Han students aged 13-18 years were in good physical condition. The qualified rates of physical fitness were significantly different by gender and age groups. Nutritional status, region, socioeconomic status, PE class, exercise time per day, homework time per day, and TV time per day were related factors of physical fitness.
ABSTRACT
Objective To understand and evaluate the characteristics of geographic distribution of high blood pressure prevalence in children and adolescents aged 7-18 years in China in 2014,and provide evidence for the prevention of hypertension in children and adolescents.Methods The data of 2014 Chinese National Surveys on Students Constitution and Health conducting 31 provinces (except Hong Kong,Macao and Taiwan) were collected.A total of 216 299 children and adolescents who had complete blood pressure records were selected as study subjects.The low,middle and high prevalence areas were identified according to their high blood pressure detection rates in the children and adolescents,<4%,4%-7% and >7%,to analyze the geographic distribution of high blood pressure prevalence in the children and adolescents.The environmental data in the capitals of 31 provinces in 2014 were collected to analyze the correlation between environmental factors and blood pressure Z score in the children and adolescents.Results The average detection rates of high blood pressure was 6.4% in 31 provinces (1.5%-14.2%).The high prevalence areas were mainly distributed in the eastern China,especially the Circum-Bohai sea area,low prevalence areas were mainly distributed in the central and western areas of China and some provinces in the east.Correlation analysis results showed that the annual average temperature,annual average air humidity and local altitude were negatively correlated with blood pressure Z score,including diastolic and systolic blood pressure,in both boys and girls.The annual average sunshine time,PM2.5 and PM10 concentrations,content of SO2 were positively correlated with blood pressure Z score in both boys and girls.Conclusions There was a significant difference in high blood pressure of children and adolescents among 31 provinces.More attention should be paid to the children and adolescents living high prevalence area.And it is necessary to understand environmental factors which can affect the blood pressure of children and adolescents.
ABSTRACT
Objective To explore the association between cesarean section and obesity in child and adolescent.Methods In this study,a total number of 42 758 primary and middle school students aged between 6 and 17 were selected,using the stratified cluster sampling method in 93 primary and middle schools in Hunan,Ningxia,Tianjin,Chongqing,Liaoning,Shanghai and Guangdong provinces and autonomous regions.Log-Binomial regression model was used to analyze the association between cesarean section and obesity in childhood or adolescent.Results Mean age of the subjects was (10.5±3.2) years.The overall rate of cesarean section among subjects attending primary or secondary schools was 42.3%,with 55.9% in boys and,40.6% in girls respectively and with difference statistically significant (P<0.001).The rate on obesity among those that received cesarean section (17.6%) was significantly higher than those who experienced vaginal delivery (10.2%) (P<0.001).Results from the log-binomial regression model showed that cesarean section significantly increased the risk of obesity in child and adolescent (OR=1.72,95%CI:1.63-1.82;P<0.001).After adjusting for factors as sex,residential areas (urban or rural),feeding patterns,frequencies of milk-feeding,eating high-energy foods,eating fried foods and the levels of parental education,family income,parental obesity,physical activity levels,gestational age and birth weight etc.,the differences were still statistically significant (OR=1.48,95% CI:1.39-1.57;P<0.001).Conclusion The rate of cesarean section among pregnant women in China appeared high which may significantly increase the risk of obesity in child or adolescent.
ABSTRACT
Objective@#To investigate the endemic distribution and related factors of elevated blood pressure in Chinese children and adolescents aged 7 to 18 years old.@*Methods@#A total of 214 354 students aged 7 to 18 years old with data integrity of height, weight, and blood pressure were selected from Chinese National Survey on Students Constitution and Health in 2014, including 31 provinces (with the exception of Hong Kong, Macao, and Taiwan) in China. The criterion of elevated blood pressure was defined by the diagnosis and treatment guideline of high blood pressure in US children and adolescent. The differences of elevated blood pressure between boys and girls and different groups of nutritional status were calculated by Chi-square test.@*Results@#The mean values of systolic pressure and diastolic pressure were (104.8 ± 12.8) mmHg (1 mmHg=0.133 kPa), and (65.4 ± 9.7) mmHg, respectively. The rate of elevated blood pressure in Chinese children and adolescents aged 7 to 18 years old was 6.4% (13 558/214 354), as well as 7.0% (7 537/106 982) in boys, and 5.7% (6 131/106 979) in girls (P<0.001). Meanwhile, the rate of elevated blood pressure was 3.2% (321/10 127), 4.9% (7 887/161 419), 9.8% (2 472/25 292), and 17.5% (2 988/17 051) in wasting group, normal group, overweight group and obesity group, respectively, which indicated a rising trend from wasting to obesity among four nutritional status groups(P<0.001).@*Conclusion@#The rate of elevated blood pressure in Chinese boys was higher than girls, especially in overweight and obese students. Therefore, the effective intervention on child and adolescent with overweight or obesity will become the key work on the prevention of high blood pressure in the future.
ABSTRACT

Objective To survey village doctors'knowledge,demand and behavior of health management,to provide scientific evidence for village people's health self-management.Methods Prepared a self-designed question-naire and make it completed by 106 village doctors chosen at random from 106 different villages in the eight towns in Guangzhou's two mountainous districts.Results The average age of the village doctors was(50.9 1 ±7.84)years, 36.79% of them had the ultimate diploma of a health technical school,and the average knowledge rate of health man-agement was 30.09%.There was remarkable difference among the 3 age groups which disclosed statistic value(χ2 =112.900,P =0.000).The 35-44 age group was the highest in the knowledge rate of health management (52.61%). The doctors with a ultimate technical diploma vary in the knowledge rate (the highest was 47.44%),which also had statistic value(χ2 =112.900,P =0.000).Only 2.83% of the village doctors believed that their health management skill can completely meetthe current demand and 3.77% can.18.87% believed that training about health management was very meaningfuland 25.47% meaningful.63.21% (most required by the health bureau) expected to receive training.16.98% didn't receive such training in the recent year because they thought it was un-necessary or not available.11.32% of the village doctors were willing to pay for the health management training,while 97.17% had never taken such training on their own expenses.Conclusion Village doctors are mostly elderly,low-educated,and insufficient in the professional knowledge of health management.Without the corresponding motivations and regulations,they are not enthusiastic about the training.It is suggested that the local authorities pay more attention to the buildup of the village health stations and improve the structure,knowledge,and earning of the village doctor group so as to ensure the effective health management service for the masses in villages.
