RESUMO

OBJECTIVE: To analyze the prevalence and variation of hypotension in Chinese adults residents in 2002 and 2010-2012. METHODS: Data of the blood pressure measurements from 2002 and 2010-2012 China National Nutrition and Health Survey(CNNHS), a multistage stratified cluster random sampling survey was conducted in 2002, and the sample size was 147 488, 64 869 males, 82 619 females, 50 123 urban residents, 97 365 rural residents, 71 078 northern residents and 76 410 southern residents. A multi-stage stratified and population-proportional cluster random sampling method was used in 2010-2012, and the sample size of was 120 427, 52 499 males, 67 928 females, 60 214 urban residents, 60 213 rural residents, 53 863 northern residents and 66 564 southern residents. The population data published by the National Bureau of Statistics in 2009 was used as a standard population of the data result for 2002 and 2010-2012. Complex sampling weighting method was adopted in data analyses. The prevalence of hypotension and 95%CI in different populations were calculated. Chi-square test was used to compare the rates, multi-factor analysis was conducted by using SURVEYLOGISTIC model regression. RESULTS: In 2002, the prevalence rate of hypotension in Chinese adults was 3. 0%, 1. 9% in males, 4. 1% in females, 2. 7% in urban residents, 3. 3% in rural residents, 2. 8% in northern residents and 3. 2% in southern residents. The prevalence rate of hypotension was the highest in 18-44 age group(4. 3%). Among people with different body mass index(BMI), the prevalence of hypotension was higher in low weight group(7. 0%). From 2010 to 2012, the prevalence rate of hypotension in Chinese adults was 2. 1%, 1. 1% in males, 3. 2% in females, 1. 9% in urban residents, 2. 2% in rural residents, 1. 8% in northern residents and 2. 3%in southern residents. The prevalence rate of hypotension was the highest in 18-44 age group(3. 1%). Among people with different BMI, the prevalence of hypotension was higher in low weight group(7. 4%). The total prevalence of hypotension in adult residents in China from 2010 to 2012 was lower than that in 2002, and the difference was statistically significant(χ~2= 624. 3, P <0. 0001). In 2002 and 2010-2012, the prevalence of hypotension in adult residents of China decreased with the increase of age, and the prevalence of hypotension in men and women also decreased with the increase of age. Women were higher than men, the lower age group was higher than the higher age group, and the lower weight group was higher than the normal population. The differences were statistically significant. Multivariate Logistic regression analysis also showed that lower age group, women and people with low weight were more prone to develop hypotension. CONCLUSION: In 2002 and 2010-2012, the total prevalence of hypotension in adult residents of China, and that of hypotension in both men and women decreased with the increase of age. Women were higher than men, the lower age group was higher than the higher age group, and the lower weight group was higher than the normal population. 18-44 age group, women and low weight group are more likely to have low blood pressure. Compared with 2002, the total prevalence of hypotension in Chinese adult residents showed a decreasing trend from 2010 to 2012.

RESUMO

OBJECTIVE: To analyze the weight recognition and control among women aged 15-49 in China. METHODS: Data was from the China National Nutrition and Health Surveillance 2010-2013. Stratified multistage cluster sampling method was used. The data of 35 664(16 914 urban women and 18 750 rural women) 15-49 years old women of childbearing age was used. The basic information was collected by questionnaires. Physical measurement indexes such as height and weight were collected. RESULTS: Among overweight and obese women of childbearing age, only 34. 9%(95%CI 34. 2%-35. 6%) of them correctly judged themselves overweight or obese, and 61. 4%(95% CI 60. 6%-62. 1%) of them thought they were normal weight; 10. 8%(95%CI10. 3%-11. 2%) of the normal-weight women thought they were overweight; while 3. 0%(95% CI 2. 6%-3. 4%) of the low-weight women thought they were overweight. Only17. 1%(95% CI 16. 4%-17. 8%) of overweight and obese women of childbearing age take weight control measures. In addition, 3. 6%(95% CI 3. 1%-4. 1%) of low-weight women of childbearing age and 9. 7%(95% CI 9. 3%-10. 1%) of normal-weight women took weight control measures, respectively. The proportion of women aged 15-24 taking weight control measures was higher than that of women aged 25-34 and 35-49, 14. 8%(95% CI 13. 3%-16. 4%), 12. 2%(95% CI 11. 1%-13. 2%) and 10. 0%(95% CI9. 3%-10. 1%), respectively. The proportion of women aged 15-24 taking weight control measures was the highest among normal weight women and overweight and obese women, 13. 9%(95% CI 13. 1%-14. 7%) and 26. 9%(95% CI 26. 4%-27. 4%), respectively. CONCLUSION: At present, there were more women of childbearing age in China who could not correctly assess their own body weight, leading to the inability to take correct weight control measures.

RESUMO

OBJECTIVE: To estimate the early initiation of breastfeeding status of Chinese children aged less than 24 months and its influence factors. METHODS: Data of children aged less than 24 months old was collected from Chinese Nutrition and Health Surveillance in 2013. Subjects were selected form 55 survey sites of mainland China by the multilevel stratified equal proportional cluster random sampling and the final effective sample size was 14 825. Caregivers of children completed a feeding and health questionnaire, which included questions on whether the children were put to the breast within one hour of birth, influence factors and the initiation time of breastfeeding. Prevalence of early initiation of breastfeeding, influence factors and time composition ratio of initiation of breastfeeding were calculated. RESULTS: The prevalence of early initiation of breastfeeding of Chinese children under 2 years old in 2013 was 26. 4%, among which big cities, small and medium-sized cities, ordinary rural areas, povertystricken rural areas were 30. 1%、24. 1%、23. 2% and 36. 9%, respectively. Caesarean section was the most important factor affecting early breastfeeding of infants in big cities, small and medium-sized cities and ordinary rural areas, accounting for 40. 7%, 51. 5%and 33. 8%, respectively. The main influencing factor in poor rural areas was lack of early breast-feeding knowledge, accounting for 44. 6%. The prevalence of infants initiated breastfeeding 2 ± 23 hours after birth was 31. 0% and the prevalence of infants initiated breastfeeding ≥24 hours after birth was 35. 3%. In big cities, the prevalence of the two periods were 31. 2% and 33. 4%. In small and medium-sized cities, the prevalence were35. 4% and 34. 4%. In ordinary rural areas, the prevalence were 26. 9% and 42. 3%. In poverty-stricken rural areas, the prevalence were comparatively low, which were 29. 5%and 23. 5%, respectively. CONCLUSION: The prevalence of early initiation of breastfeeding among infant aged less than 24 months is low in China. Caesarean section and lack of related knowledge were the main influencing factors in urban and rural areas respectively. Certain percentage of infants have severely delayed breast contact with their mothers and start breastfeeding.

RESUMO

OBJECTIVE: To describe the hypertension awareness, treatment and control among adults in China in 2010-2012. METHODS: Data was from the China Nutrition and Health Surveillance in 2010-2012. A stratified multistage cluster sampling was used from 31 provinces, autonomous regions, and municipalities and selected 150 districts/counties. The sample was adults aged 18 and over selected through the method of Probability Proportion to Size(PPS). The mercury sphygmomanometer was used to measure the blood pressure. Each person had three measurements. The questionnaire was used to collect the information of hypertension awareness and control. RESULTS: The sample participants were 120 428 in 2010-2012. Among adults with hypertension, 46. 5%were aware of their hypertension, 41. 1% reported taking hypertension medicine in the last two weeks, and 13. 8% controlled the blood pressure. It was higher for hypertension awareness, treatment and control in women(49. 5%, 44. 2% and 14. 6%) than those of men(43. 0%, 37. 4% and 12. 9%). The three rates were increased with age. The prevalence of control was 33. 6% among the treated hypertensive individuals. It was higher for men and the rate was decreased with age. It was higher for hypertension awareness, treatment and control among hypertension and control among treated hypertensive participates in urban area(52. 7%, 47. 9%, 17. 9% and 37. 3%) than those in rural area(39. 5%, 33. 4%, 9. 2% and 27. 6%). The rates of overall, gender, and age groups were decreased in large city, medium and small city, general county, and poor county. CONCLUSION: The prevalence of hypertension awareness, treatment and control among hypertension and control among treated hypertensive participates among Chinese adults was increased in 2010-2012. But the rates were still keep a low level. The region and age differences need pay attention.

RESUMO

OBJECTIVE: To analyze the trends and food sources composition of energy, protein and fat in Chinese residents from 1992 to 2012. METHODS: Based on the dietary data of the China Nutrition and Health Surveys in 1992, 2002 and 2010-2012, to compare the food sources composition of energy, protein and fat in Chinese residents. A stratified multistage cluster random sampling was used in 1992, and the sample size was100 201. A multistage stratified cluster random sampling survey was conducted in 2002, and the sample size was 68 962. A multi-stage stratified and population-proportional cluster random sampling method was used in 2010-2012, and the sample size of was63 993. Three consecutive 24-hour recalls method and face-to-face interviews were used in three dietary surveys, and household edible oil and condiment weighing were adopted in three surveys. The dietary energy, carbohydrate, protein and fat intake, and the proportion of dietary pattern among the participants were analyzed based on the China Food Composition table. RESULTS: The average daily dietary energy intake in Chinese residents in 1992, 2002 and 2010-2012 was 2328. 3, 2250. 5 and 2172. 1 kcal, respectively. The carbohydrate intake was 378. 4, 321. 2 and 300. 8 g respectively, and the protein intake was 68. 0, 65. 9 and 64. 5 g, respectively. The fat intake was 58. 3, 76. 2 and 79. 9 g, respectively. The dietary energy in Chinese residents mainly came from cereals, and the proportion of cereals energy supply was 66. 8%, 57. 9% and 53. 1%, respectively. Dietary energy was mainly derived from carbohydrates, and the proportion of carbohydrate energy supply was 66. 2%, 58. 6% and 55. 0%, respectively. The proportion of fat energy supply was 22. 0%, 29. 6% and 32. 9%, respectively. The main food sources of protein was cereals. The proportion of protein intake in cereals was 61. 6%, 52. 0% and47. 3%, respectively. The proportion of high quality protein intake was 24. 0%, 32. 6%and 37. 0%, respectively. The main food sources of fat was plant food, and the proportion of plant fat intake was 62. 8%, 60. 8% and 64. 1%, respectively. The dietary energy in urban and rural residents in 1992, 2002 and 2010-2012 years was mainly derived from cereals. The nutrients of dietary energy were mainly derived from carbohydrates. The food sources of protein were mainly cereals. The food sources of fat were mainly plant food, and the proportion of high quality protein intake increased. The proportion of cereals supply in 2002 and 2010-2012 years was less than 50%. The fat supply of urban residents was 35. 0% and 36. 1% higher than that in 2002 and 2010-2012, and the proportion of high quality protein intake in rural residents was less than 40%. CONCLUSION: The dietary composition in urban and rural residents in 1992, 2002 and 2010-2012 was mainly composed of cereal and vegetable food. The proportion of energy supply from fat was very high and increased, the average dietary intake per reference man per day for protein intake was insufficient and decreased. The trend of average energy intake per reference man per day was from excessive intake to insufficient and decreased in Chinese residents and urban residents. The proportion of high quality protein intake was insufficient for the Chinese residents and rural residents. The proportion of energy supply from cereals and carbohydrate were low and decreased.

RESUMO

OBJECTIVE: To describe complementary feeding time among 0-5 years old children in 2013 in China. METHODS: Data was from the China Nutrition and Health Surveillance in 2013. A stratified multistage cluster sampling was used from 31 provinces( autonomous regions and municipalities) and selected 55 districts/counties. The study included 24 580 children aged 0-5 years. The basic situation and complementary feeding of children aged 0-5 years were collected by questionnaires. RESULTS: The average time for children aged 0-5 years in China to start complementary foods was 6. 1 months. The urban( 5. 7 months) was earlier than the rural( 6. 4 months), large cities, medium and small cities, general rural and poor rural areas were 5. 5, 5. 8, 6. 9 and 5. 5 months, respectively. The proportions of early complementary feeding( < 4 months) and late complementary feeding( > 9 months) were 10. 2 %( n = 2496) and 9. 5%( n = 2336), which were 7. 3% and 5. 5% respectively in urban area and 13. 1% and 13. 7%respectively in rural area. The proportions of early complementary feeding was the highest( 19. 6%) in poor rural areas, the proportions of late complementary feeding was the highest( 15%) in the general rural areas. The rate of introduction of solid, semi-solid or soft foods was 82. 3%, the urban( 89. 4%) was higher than the rural( 73. 6%), and it was the lowest( 63. 4%) in the poor rural areas. CONCLUSION: There were both early complementary feeding and late complementary feeding among 0-5 years children in China in 2013, and the regional difference were significant. It is more likely to add complementary foods too early or too late in rural areasthan in urban areas, especially in poor rural areas.

RESUMO

OBJECTIVE: To estimate the instant noodles' consumption status of Chinese population in 2010-2012. METHODS: Data were collected from Chinese Nutrition and Health Surveillance in 2010-2012. A total of 78 466 valid subjects aged 6 years old and above were enrolled into analysis. The food frequency questionnaires were used to collect food consumption status information. Consumption rate, consuming frequency percentage, consumption of instant noodles, and sodium intake from instant noodles were calculated. RESULTS: The instant noodles' consumption rate of Chinese people aged 6 years old and above in 2010-2012 was 49. 7%, urban and rural were 49. 7% and 49. 8%respectively, male and female were 51. 6% and 48. 3% respectively. The consumption rate of children and adolescent aged 6-17 years old was 74. 6%. The food frequency were at least once/week 49. 0%, 1-3/month 36. 2%, < 1/month 14. 8%. The mean of instant noodles consumption per person per day was 17. 7 g. The mean of sodium consumption from instant noodles per person per day was 202. 5 mg. The instant noodlesand sodium's consumptions, of children and adolescent aged 6-17 years old were 21. 7 g and 248. 6 mg, decreased with increase of age. CONCLUSION: The consumption of instant noodles in China is common, and the high consumption of children and adolescent should be paid attention.

RESUMO

OBJECTIVE: To describe the mean of systolic blood pressure( SBP), diastolic blood pressure( DBP), and the prevalence of hypertension among 6-17 years old children and adolescents in China in 2010-2012. METHODS: Data was from the China Nutrition and Health Surveillance in 2010-2012. The total number was 35 657 which selected through the method of multi-stage stratified cluster randomization sampling and probability proportion to size( PPS). The study objects were 6-17 years old childrenand adolescents in 31 Provinces and 150 sites in China Mainland. Blood pressure was measured by mercury sphygmomanometer. Hypertension was defined using Blood pressure reference standards for Chinese children and adolescents( 2010). Age-standardized result were calculated incorporating a sample weighting using the national census from the National Bureau of Statistics in 2009. RESULTS: The overall mean SBP was 101 mmHg. It was 102 mmHg for boys and 99 mmHg for girls. It showed 94 mmHg and 105 mmHg in 6-11 and 12-17 age groups. The mean DBP was 65 mmHg. Both boys and girls were 65 mmHg. It was 61 mmHg and 68 mmHg in 6-11 and 12-17 age groups. The prevalence of hypertension was 12. 4% in children and adolescents in China. It was 12. 4% in boys and 12. 3% in girls. It showed 7. 3% in 6-11 age group and 15. 6% in 12-17 group. The SBP, DBP and prevalence of hypertension were increased with age. The mean SBP of poor rural area was lowest and there was no difference in SBP and hypertensive prevalence. CONCLUSION: The government should pay more attention on blood pressure and hypertension in 6-17 years old children and adolescents. It is important to strengthen the surveillance and early detection and prevention.

RESUMO

OBJECTIVE: To analyze the status and variation trend of eggs food intake among Chinese residents. METHODS: Multi-stage cluster randomization sampling method was used to collect data about eggs food intake among residents in 150 surveillance sites of China National Nutrition and Health Survey in 31 provinces of China from 2010 to 2012. Food frequency questionnaire and 24-hours recall for three consecutive days were used to collect information on eggs food consumption of the participants. The eggs food intake per standard people were calculated based on the China Food Composition. RESULTS: The proportion of residents reporting the frequency of 1 or more times per day for eggs food were 31. 3% in the children and 25. 8% in the adult and the estimated daily eggs food was24. 3 grams for all the residents. The estimated daily eggs food for the residents of urban( 29. 5 g) was higher than that of rural( 19. 4 g)( T = 47. 86, P < 0. 0001). The eggs food consumption frequency and intake showed a decreasing trend for the residents with different residential regions in an order of big cities, small and medium-sized cities, common rural area, and poverty rural area. In past 30 years, the eggs food intake was increased substantial in the residents from 1982 to 2002. Althought the total the eggs food intake was increased gradually for all residents from 2002 to 2010-2012, the eggs food intake was decreased slightly for both the residents in urban and rural areas during the period. CONCLUSION: The consumption frequency and intake of eggs food among Chinese residents are still at a low level and exist regional differences. Some measures should be taken to guide reasonable eggs food consumption behavior among Chinese residents.

RESUMO

OBJECTIVE: To examine the trend of stunting and wasting among children age between 6 and 17 in China. METHODS: A multistage cluster random sampling process was used to investigate 36 058 children aged 6-17 years in 2010-2012 in 31 provinces( municipalities, autonomous region) in China. Their height and weight were measured, prevalence of stunting and wasting were calculated according to national standard of malnutrition screening among school children and adolescents( WS/T 456-2014) to compare children malnutrition status in children and adolescents in four classified areas. Data was weighted by post stratification adjustment, according to standard population data in 2009 from State Statistical Bureau. RESULTS: The prevalence of stunting among childrenand adolescents aged 6 to 17 in China in 2010-2012 were 3. 2%( 95% CI 2. 6%-3. 8%), among boys were 3. 6%( 95% CI 2. 9%-4. 3%) and girls were 2. 8%( 95%CI 2. 2%-3. 3%). Stunting rate among children and adolescents aged 6-17 in urban area were 1. 5%( 95% CI 1. 0%-2. 1%), and rural area were 4. 7%( 95% CI 3. 8%-5. 6%). Prevalence of stunting showed rising trend with the decline of economic level. Total prevalence of wasting among children and adolescents aged 6 to 17 years in China in2010-2012 were 9. 0%( 95% CI 8. 0%-9. 9%), 10. 4%( 95% CI 9. 3%-11. 6%)for boys and 7. 3%( 95% CI 6. 5%-8. 1%) for girls, 7. 8%( 95% CI 6. 6%-9. 0%)for urban area and 10. 0%( 95% CI 8. 6%-11. 4%) for rural area. Prevalence of wasting also showed rising trend with the decline of economic level. CONCLUSION: The overall prevalence of stunting and wasting among Chinese children and adolescents in 31 provinces( municipalities, autonomous region) was relatively low, however, stunting and wasting in poor areas should still be concerned.

RESUMO

OBJECTIVE: To understand the status and trend of added sugar containing food consumption from 2002 to 2012. METHODS: Using dietary data from the Chinese Nutrition and Health Survey in 2002 and the Chinese Nutrition and Health Surveillance in 2010-2012, to analyze the consumption status of added sugar containing food in these two years and to compare the difference between the past ten years in China. RESULTS: From 2002 to 2012, consumption rate of added sugar containing food increased from 20.4% to 26.9%, the consumption rate of all ages in 2012 was higher than in 2002 (t = -3.75, P = 0.0133), female higher than male (t = 0.86, P = 0.3991). The percentage of total calories from added sugar containing food was decreasing from 9.48% in 2002 to 9.09% in 2012, the difference was statistically significant (t = 4.16, P < 0.0001). From 2002 to 2012, species composition ratio of sugar-sweetened beverages (11.7% and 8.5%), dairy products (8.1% and 15.0%), instants food (26.6% and 39.0%) was increasing in some degree. CONCLUSION: The consumption level of added sugar in China is low, which still under the recommended limits (10%) of WHO, but the consumption rate of food containing added sugar is increasing generally.

RESUMO

OBJECTIVE: To analyze the consumption of fruits and vegetables of Chinese adults. METHODS: Data were collected from 2010-2012 China National Nutrition and Health Surveillance. Information on fruits and vegetables consumption was collected by using the 24 h recall method for 3 consecutive days. Using the multi-stage stratified cluster randomization sampling method. The participants selected were more than 18 years old of 150 counties from 31 provinces in China. Age and sex standardization was performed based on the China 2009 population published by National Statistics Bureau. The average consumption of vegetables or fruits after weight adjustment for complex sampling was reported to analyze the consumption of fruits and vegetables of Chinese adults (x ± Sx). RESULTS: The average daily consumptions of vegetables and fruits for Chinese residents were (255 ± 6) and (36 ± 3)g/d, respectively. The total consumptions of fruits and vegetables were (291 ± 7)g/d, (295 ± 8)g/d for male, (286 ± 7)g/d for female. Rates on intake of vegetables in Chinese adults during the three survey days were 99.0%-99.8%.Rates on intake of fruits of urban and rural residents were 36.9%-51.5% and 21.3%-30.3%,respectively.The proportion of people whose total amount of vegetables and fruits intake reached 400 g/d were 24%-28% and 13%-23% in urban and rural areas, respectively. In urban and rural areas, the proportion of adults whose consumption reached Chinese dietary guidelines recommended level were 22%-26% and 14%-19% in vegetables, 2%-5% and 1%-2% in fruit, respectively. CONCLUSION: The consumptions of vegetables and fruits were inadequate in Chinese adults.

RESUMO

OBJECTIVE: To study the consistency between the electronic sphygmomanometer and mercury sphygmomanometer on blood pressure measuring in children and adolescents. METHODS: 201 children and adolescents were from 6neighborhood of Hunan Province. Dr Mike BPA100 Plus electronic sphygmomanometer was used for three times to test the difference. The blood pressure value of mercury sphygmomanometer was gold standard. The difference of systolic pressure and diastolic pressure of two devices was tested using paired t test, Bland-Altman analysis, and interclass correlation coefficient. RESULTS: Paired t test showed the statistical difference on the systolic pressure( t = 24. 71, 0. 0001) and diastolic pressure( t = 23. 81, < 0. 0001) of two devices. Both the systolic pressure and diastolic pressure of electronic sphygmomanometer was higher than that of mercury sphygmomanometer. Bland-Altman analysis showed mercury sphygmomanometer couldn 't be simply replaced by electronic sphygmomanometer. The result of interclass correlation coefficient presented a poor consistency between two devices. CONCLUSION: In order to get scientific conclusion, the comparable study between two blood pressure measuring devices should be conductedbefore a large-scale survey on child and adolescent.

RESUMO

OBJECTIVE: To analyze the trends of food consumption among Chinese population from 1992 to 2012. METHODS: Based on the results of 1992, 2002 and 2010-2012, data of average food consumption per reference man per day was compared. The 3-consecutive day-24-hour dietary recall was used to collect information on food intake, but the condiment intake was collected by weighting method. RESULTS: The intake of cereals decreased during 1992-2012 from 439. 9 g to 337. 3 g, tubers decreased 50. 8 g during20 years. The intake of fresh vegetables was decreased from 310. 3 g to 269. 4 g from 1992 to 2012, with rural area decreased more than urban area. Fruit intake in urban area decreased from 80. 1 g to 28. 8 g, whereas rural area had minor variation. The intake ofmeats increased from 58. 9 g to 89. 7 g. There were little change on the intake of legume, dairy, fishery and their products. Intake of edible oil was increased during 1992-2002but kept stable during 2002-2012. Salt intake was 3. 4 g less in 2010-2012 than 1992 and 1. 5 g less in 2010-2012 than 2002. CONCLUSION: There had been noticeable changes in dietarypattern among Chinese population in the past 20 years. Even though Chinese dietary pattern had kept stable since 2002 and had much improved, improper food consumption still existed. Double burdens should be considered as problems which asked for attention by the government and researchers.

RESUMO

OBJECTIVE: To describe the energy and dietary nutrients intake trends among Chinese population from 2002 to 2012. METHODS: Data of energy, macronutrient, and micronutrient intake were collected from 2002 Chinese Nutrition and Health Survey, 2010-2012 Chinese Nutrition and Health Surveillance, and energy and dietary nutrients intake were analyzed. The 3-consecutive days-24-hour dietary recall and food weighting method were used to collect food, edible oil and condiment intake information. The dietary nutrients intake was calculated based on the energy percentage in one family and the China Food Composition. RESULTS: Compared with 2002, the average energy intake per reference man per day of Chinese people declined to 2172. 1 kcal from 2250. 5 kcal in 2010-2012. Dietary protein intake was basically flat. Dietary fat intake in 2010-2012 was 79. 9 g, with urban level higher than rural level. Compared with that in 2002, fat intake increased by 4 g, and urban residents' intake fell slightly, making urban / rural gap narrower. Theintake of micronutrient such as vitamin A, vitamin C, calcium, iron, zinc was still lower than Chinese Dietary Reference Intakes and falling continually. CONCLUSION: In the last decade, Chinese urban / rural residents' dietary energy supply was sufficient, and the dietary nutrients intake had improved. However, there were excessive intake of fat and low intake of micronutrient was still a problem among Chinese population. There was significant difference between the urban and rural area, and the dietary quality among Chinese population especially rural residents should be improved.

RESUMO

OBJECTIVE: To analyze the status of consumption of potato and its related products in Chinese residents from 2010 to 2012. METHODS: Data was from China Nutrition and Health Surveillance 2010-2012. Information on the consumption of potato and its related products was collected using the 24 h recall method for three consecutive days. RESULTS: The average consumption of potatoes for Chinese residents was 29. 2 g / d, 20. 1 g for urban residents, 37. 7 g for rural residents. The consumption rate of potato was40. 1%, which were 35. 7% and 44. 2% in urban and rural areas. The average consumption of potato eaters was 72. 8 g, 56. 2 g and 85. 3 g for urban and rural areas respectively. The average consumptions of potato powder and chips were 0. 2 g and 0. 04 g, and the edible rate were 0. 4% and 0. 2% respectively. CONCLUSION: At present, the edible rate and the consumption of potato were lower in Chinese residents. To promote potato staple strategy should actively promote potato food products and industrial development, guide the dietary structure of Chinese residents, and improve the residents' understanding of the nutritional value of potato.

RESUMO

OBJECTIVE: To compare the electronic sphygmomanometer with mercury sphygmomanometer on measuring the average blood pressure, prevalence of hypertension in a same population. To set up a numerical relationship between two blood pressure value of the two devices. METHODS: 544 adults of ≥ 18 years old were from 6 neighborhood of Hunan Province. OMRON HEM-907 and mercury sphygmomanometer were used to test the difference. The blood pressure value of mercury sphygmomanometer was gold standard. The difference of systolic pressure and diastolic pressure of two devices was tested using paired t test and Bland-Altman analysis. Chi-square test was used to analyze the two prevalence of hypertension among the same population. The equation of linear regression was established using the value of blood pressure of two devices. RESULTS: Paired t test showed the statistical difference on the systolic pressure and diastolic pressure of two devices (P < 0.0001). Chi-square test presented a higher prevalence of hypertension by using the electronic sphygmomanometer (P < 0.0001). Bland-Altman analysis showed mercury sphygmomanometer couldn't be simply replaced by electronic sphygmomanometer. The two independent equation of linear regression was calculated on systolic pressure and diastolic pressure. CONCLUSION: The difference still existed when using the electronic sphygmomanometer and mercury sphygmomanometer at a large scale population. It's important to conduct the comparative study on electronic sphygmomanometer and mercury sphygmomanometer.

RESUMO

Sodium butyrate (NaBu), a histone deacetylase inhibitor, has been shown to inhibit cell growth, induce cell differentiation and apoptosis in multiple cell lines. In present study, we revealed the dual effects of NaBu in regulating hepatocellular carcinoma (HCC) cells. In two different HCC cell lines, SK-Hep1 and SMMC-7721, low concentrations of NaBu induced a significant increase in cell growth ratio and S-phase cell percentage, accompanied by a reduced p21 Cip1 expression at both mRNA and protein levels, while dissimilarly, high concentrations of NaBu inhibited cell growth and induced G1 arrest through up-regulation of p21 Cip1 and p27 Kip1 protein expression. The reduction of p45 Skp2 expression further indicated that the ubiquitin-mediated protein degradation might play a role in NaBu-induced up-regulation of p21 Cip1 and p27 Kip1. Moreover, the high concentration of NaBu was also able to trigger HCC cell apoptosis. Taken together, these results demonstrate the distinct effects of NaBu at different dosages. This finding may contribute to develop more effective tumor therapeutic protocols of NaBu in HCC.

RESUMO

The α1,3/4-fucosyltransferases (FUT) subfamily are key enzymes in cell surface antigen synthesis during various biological processes. A novel role of FUTs in tumorigenesis has been discovered recently, however, the underlying mechanism remains largely unknown. Here, we characterized FUT6, a member of α1,3/4-FUT subfamily, in human hepatocellular carcinoma (HCC). In HCC tissues, the expression levels of FUT6 and its catalytic product SLe(x) were significantly up-regulated. Overexpression of FUT6 in HCC cells enhanced S-phase cell population, promoted cell growth and colony formation ability. Moreover, subcutaneously injection of FUT6-overexpressing cells in nude mice promoted cell growth in vivo. In addition, elevating FUT6 expression markedly induced intracellular Akt phosphorylation, and suppressed the expression of the cyclin-dependent kinases inhibitor p21. Bath application of the PI3K inhibitor blocked FUT6-induced Akt phosphorylation, p21 suppression and cell proliferation. Our results suggest that FUT6 plays an important role in HCC growth by regulating the PI3K/Akt signaling pathway.
