ABSTRACT
Objective@#To analyze the average systolic blood pressure (SBP) and diastolic blood pressure (DBP) among adults aged 18 years old and above in China between 2010 and 2012; and to compare the difference in the results measured by mercury sphygmomanometer and converted electronic sphygmomanometer.@*Methods@#The data was collected from Chinese Nutrition and Health Surveillance in 2010-2012. 120 428 adults aged 18 years old and above were selected from 150 survey counties (districts) of 31 provinces in China Mainland, by multi-stage stratified and probability proportion to size (PPS) cluster randomization sampling method. The average blood pressure value was calculated from three systolic and diastolic blood pressure readings measured by mercury sphygmomanometer. The value of Electronic Sphygmomanometer was converted by regression formula. Age-standardized results were calculated incorporating a complex sample weighting using the population data from the National Bureau of Statistics in 2009.@*Results@#The overall adjusted mean of SBP based on the value of mercury sphygmomanometer among Chinese adults aged 18 years old and above was 122 mmHg (1 mmHg=0.133 kPa), 124 mmHg in men and 120 mmHg in women. The average SBP value was separately 115, 127, and 137 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average SBP was 122 mmHg in urban and 122 mmHg in rural areas. Mean DBP was 78 mmHg, 79 mmHg in men and 76 mmHg in women. The average DBP was separately 75, 81, and 81 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was 78 mmHg in urban and 77 mmHg in rural areas. The overall adjusted mean of SBP based on converted electronic device was 129 mmHg,130 mmHg in men and 127 mmHg in women, respectively. The mean of SBP was separately122, 134, and 143 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. Mean SBP was both 129 mmHg in urban and in rural areas. Mean DBP was 76 mmHg, 78 mmHg in men and 75 mmHg in women, respectively. The average DBP was separately 74, 79, and 79 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was both 76 mmHg in urban and rural areas.@*Conclusion@#The average SBP and DBP was different between the mercury sphygmomanometer and converted electronic device. However, the results from both measures showed that the blood pressure was higher in men than in women, the blood pressure increased with the increase of age, and there was no difference between urban and rural areas.
ABSTRACT
Objective@#To investigate the average dietary nutrients intake status among Chinese residents between 2010-2012, and to compare the difference between rural and urban areas.@*Methods@#Data were collected from Chinese Nutrition and Health Surveillance between 2010-2012. Based on regional features and economic development levels, China's county-level divisions were classified into four types: big city, medium and small city, ordinary rural area and poor rural area. A total of 62 857 valid subjects, including 14 017, 16 539, 19 910 and 12 391 respondents in each group separately, were enrolled by Multi-stage stratified proportion to the population cluster random sampling method. The dietary survey was conducted by recalling the 24 h diet in 3 consecutive days and weighting condiment. The daily dietary intake of energy, macronutrient, dietary fiber, vitamin, and mineral substance per resident were calculated based on China Food Composition.@*Results@#The average energy intake per resident in Mainland China was 9 047.1 kJ, with highest (9 719.3 kJ) in poor rural area and lowest (8 490.4 kJ) in medium and small city. The average dietary protein intake was 64.2 g, with highest (73.9 g) in big city and lowest (60.7 g) in poor rural area. The average dietary fat intake was 79.7 g, with highest (89.4 g) in big city and lowest (70.6 g) in poor rural area. The average intake of micronutrients of vitamin A, vitamin B2, vitamin C, calcium, iron, phosphorus, zinc was separately 441.9 μg, 0.8 mg, 80.1 mg, 364.3 mg, and 21.4 mg; which were lower than Chinese Dietary Reference Intakes. The percentage of population whose average intake of vitamin A, vitamin B2, vitamin C, calcium were lower than estimated average requirement was separately 77.0%, 90.2%, 67.7%, and 96.6%.@*Conclusion@#The supply of 3 macronutrient was sufficient in mainland China. However, it was a common issue that there was excessive intake of fat but deficient intake of micronutrients such as vitamin, calcium, iron and zinc. There were differences in nutrition intake among big city, medium and small city, ordinary rural area and poor rural area.
ABSTRACT
Objective@#To invesigate the epidemic status of the metabolic syndrome (MS) among mainland Chinese adolescents aged 10-17 in 2010-2012.@*Methods@#Data were collected from Chinese Nutrition and Health Surveillance in 2010-2012. Multi-stage stratified proportion to the population cluster random sampling method was conducted to determine 16 872 adolescents in 150 counties from 31 provinces in mainland China. The epidemic status of metabolic syndrome was analyzed by China criterion (defined by Chinese Pediatric Society, Chinese Medical Association) and Cook criterion, respectively. The prevalence of MS and 95%CI were calculated through weighted complex sampling processing by population data released by the National Bureau of Statistics in 2009.@*Results@#Based on China criterion, the weighted prevalence of MS was 2.4% (95% CI: 2.1%-2.6%) among Chinese adolescents aged 10-17. Prevalence in urban was higher than in rural (2.8%, 95%CI: 2.4%-3.2% and 1.9%, 95%CI:1.6%-2.3%, respectively). Prevalence in boys and girls were 2.7% (95% CI: 2.3%-3.0%), and 2.0% (95% CI: 1.7%-2.4%), respectively. Based on Cook criterion, the weighted prevalence was 4.3% (95% CI: 4.0%-4.7%) . The highest weighted prevalence of the components of the metabolic syndrome was low high-density lipoprotein cholesterol (26.8%, 95% CI: 26.0%-27.5%), followed by high fasting glucose (11.5%, 95% CI: 11.0%-12.0%), abdominal obesity (11.1%, 95%CI: 10.6%-11.7%) , hypertriglyceridemia (8.8%, 95%CI: 8.4%-9.3%) , and high blood pressure (6.4%, 95% CI: 6.0%-6.8%).@*Conclusion@#Among the five indicators of metabolic syndrome, the prevalence of central obesity and hypertriglyceridemia were relative high in Chinese adolescents aged 10-17 years, though the prevalence of metabolic syndrome was not high.
ABSTRACT
Objective@#To investigate the epidemiological characteristics of waist circumference (WC) and abdominal obesity (AO) among Chinese adults aged 18 and above.@*Methods@#Data were collected from China National Nutrition and Health Surveillance in 2010-2012. Multi-stage stratifies proportion to the population cluster random sampling method was conducted to determine 120 265 subjects aged 18 and above at 150 counties in 31 provinces in China mainland. WC was determined for all subjects, and AO was judged according to the "Healthy Adult Weight Determination" (WS/T 428-2013). Using the demographic data published by the National Bureau of Statistics of China in 2009, we performed complex sampling weighted treatment to calculate the WC, AO rate and 95%CI.@*Results@#The mean WC of Chinese men aged 18 and above was 82.8 cm, which of urban men (84.1 cm) was higher than that of rural men (81.4 cm) (P<0.001). The average WC of women was 78.5 cm. There was no statistical difference between urban (78.7 cm) and rural women (78.4 cm) (P=0.965). With the increase of education level, the mean WC of male increased gradually from 81.2 cm to 84.3 cm (P<0.001), and the mean WC of female decreased from 80.3 cm to 74.3 cm (P<0.001). With the family income rose, the mean WC of men increased gradually from 81.9 cm to 84.7 cm (P<0.001), and the mean of WC of women decreased from 78.8 cm to 77.6 cm (P<0.001). The AO rate was 25.7% (95% CI: 23.7%-27.7%) in adults aged 18 years and older. The AO rate in urban males (29.8% (95%CI: 26.5%-33.1%)) was significantly higher than that of rural males (22.3% (95%CI: 19.3%-25.2%)) (P=0.001). There was no significant difference in the female AO rate between urban (25.6% (95%CI: 22.8%-28.4%)) and rural areas (25.1% (95%CI: 22.2%-27.9%)) (P=0.772). With the increase of the educational level, the AO rate of men increased from 20.1% (95%CI: 18.0%-22.1%) to 32.6% (95%CI: 28.6%-36.6%) (P<0.001), the rate of women decreased gradually from 31.3% (95%CI: 28.7%-33.9%) to 13.5% (95%CI: 10.9%-16.1%) (P<0.001). With the increase of family income, the AO rate of male increased gradually from 23.3% (95%CI: 20.7%-25.9%) to 31.8% (95%CI: 27.6%-36.1%) (P<0.001), the rate of female decreased from 26.5% (95% CI: 24.2%-28.7%) to 20.0% (95% CI: 17.2%-22.8%) (P<0.001).@*Conclusion@#The prevalence of AO among Chinese residents aged 18 years and above was high, and there were significant differences in WC and AO rate between men and women under different age, region, educational level and family income level.

ABSTRACT
Objective:To determine the prevalence, disease burden, and possible causes of lung cancer. Population-based lung cancer registration data collected from 1993 to 2012 were used to analyze the lung cancer epidemic status in Qidong City. Methods:Joinpoint regression was used to calculate the trend of incidence and mortality for lung cancer. Age-period-cohort model was used to assess the effects of age and exposure on the incidence and mortality rates. Results:Upward trends were observed both for the incidence and mortality rates of lung cancer. The risk of incidence and mortality increased with age. According to the cohort effect, the risk of lung cancer increased with recent birth dates. Women had higher risk than men. Conclusion:The incidence and mortality rates of pulmo-nary neoplasms have annually increased, and the exposure to risk factors for lung cancer gradually increases. Among the community population in Qidong City, people over 70 years belong to the high-risk groups.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the mean population intake of salt in Chinese adults in 2010-2012.</p><p><b>METHODS</b>Data were from the Chinese Nutrition and Health Surveillance in 2010-2012. The samples were selected through the method of probability proportion to size (PPS). The study objects were 55 531 adults aged 18 and over from 150 sites in 31 provinces, autonomous regions or municipalities in China. The information of oil, salt and other condiments for household was from the 3 d food weighed record. The average of salt intake for individuals was calculated based on the energy percentage in one family.
