ABSTRACT
Objective To understand the prevalence of alcohol drinking and influencing factors in female adults in China.Methods At the 150 survey sites where 2010-2012 Chinese nutrition and health surveillance was conducted,a face to face questionnaire survey was conducted in female adults selected through multi-stage stratified cluster random sampling.Sample weights was assigned to each participant based on the study design by using national population census data in 2009.The complex sampling and unconditional multivariate logistics regression analysis was conducted to identify the influencing factors for the prevalence of alcohol drinking in the female adults.Results A total of 75 518 participants were included in this study.The prevalence of drinking in female adults was 13.9％ (95％CI:11.7-16.2) in urban area and 13.3％ (95％CI:9.4-17.2) in rural area.The prevalence of frequent drinking was 13.9％ (95％CI:9.9-17.9) in women in urban area and 14.2％ (95％CI:10.8-17.6) in women in rural area.The prevalence of excessive drinking was 11.1％ (95％CI:7.5-14.8) in women in urban area and 12.8％ (95％CI:9.1-16.4) in women in rural area.The prevalence of wine drinking in women in urban area was significantly higher than in women in rural and had positive correlation with income and education levels.The social and economic factors influencing drinking behavior of the female adults included occupation,drinking behaviors of family members and smoking behavior.Those who were engaged in agriculture,production and transportation (OR=0.72,95％CI:0.56-0.94,P=0.016),housework (OR=0.59,95％CI:0.44-0.78,P＜0.001) and other work (OR=0.61,95％CI:0.43-0.85,P=0.004) had lower drinking prevalence.Whereas those whose family members had drinking behavior (0R=2.66,95％ CI:2.17-3.26,P＜0.001) and those who were current smokers (OR=4.32,95％CI:2.95-6.34,P＜0.01) had higher drinking prevalence.Conclusions The prevalence of drinking,frequent alcohol drinking and excessive drinking were relatively low in female adults in China.Occupation,drinking behaviors of family members and smoking behavior were the main factors influencing the prevalence drinking behavior in female adults in China.
ABSTRACT
Objective To investigate the drinking status and associated factors in adults in China.Methods Based on the 2010-2012 China National Nutrition and Health Survey (CNNHS),a total of 135 824 participants aged ≥18 were included in this cross-sectional analysis.Multivariable logistic regression model was used to investigate the associated factors for drinking status.Results The overall drinking rate was 30.5％ in Chinese adults,53.8％ in men,and 12.2％ in women.The excessive drinking rate was 14.0％ in men and 1.1％ in women.The daily drinking rate was 25.7％ in men and 10.9％ in women.Men mainly consumed multi-type wines,but women preferred beer.The overall harmful drinking rate was 7.1％.The excessive drinking rate,daily drinking rate,and harmful drinking rate increased first but then declined with age.All the four rates were positively related with physical activity.Conclusions The drinking rate,excessive drinking rate,daily drinking rate and harmful drinking rate were high in adults in China.Drinking status was associated with age,sex,marital status,education level,smoking status and physical activity.
ABSTRACT
Objective To explore the relationship between meat consumption and metabolic syndrome (MS) in Chinese adults aged ≥18 years.Methods The data were obtained from 2010-2012 National Nutrition and Health Survey.A total of 34 923 subjects who completed the dietary survey,the physical examination and had the testing results of blood sugar and blood lipid levels were enrolled in this study.MS was defined according to the diagnostic criteria of China Diabetes Society 2013.The prevalence ratios of MS and each form of MS and related 95％CI were calculated after post stratification weight according to the population data (2009) released by the national bureau of statistics.Results The average meat intake among subjects was 94.8 g/d.People who had meat consumption between 100 g/d and 199 g/d had the lowest prevalence of MS,abdominal obesity and hyperglycemia.As the meat consumption increased,the prevalence of MS in men increased.Men who had meat consumption of ≥300 g/d had a higher risk of MS than those who had low level of meat consumption,with prevalence ratio equaled to 1.46 (95％CI:1.14 ～ 1.87).Similar trend was not observed in women.Conclusion Moderate intake of meat is associated with reduced risk of MS in Chinese adults.
ABSTRACT
Objective To understand the prevalence of alcohol drinking in 20-79 years old males with different educational backgrounds and smoking behaviors in different areas of China.Methods A multi-stage cluster random sampling survey was conducted in 150 surveillance sites in 2010-2012 Chinese nutrition and health surveillance in China.At least 1 000 subjects were selected in each surveillance site.Alcohol drinking prevalence and pattern information were collected by using personal health and food frequency questionnaire in face to face interviews.Results A total of 60 791 males aged 20-79 years were surveyed.The prevalence of alcohol drinking was 57.8％ (58.3％ in rural area,57.3％ in urban area).The mean daily alcohol intake level was 32.7 g (33.3 g in rural area,32.1 g in urban area).The rate of almost drinking every day and daily alcohol intake level were highest among males aged 50-59 years.Mean daily alcohol intake level,rate of almost drinking every day and excessive drinking decreased with the increase of education level.Non-smokers had higher rate of never drinking and lower prevalence of drinking and excessive drinking,lower mean daily alcohol intake level,and lower rate of almost drinking every day compared with current and past smokers.Conclusions Alcohol drinking was common in males aged 20-79 years in China,and,the difference was not obvious between rural residents and urban residents.The differences in daily intake level of different alcohol drinks among males with different characteristics had certain significance.Significant difference in excessive drinking was found among different age groups,those with different education levels and those with different smoking history.

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
<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. The results presented the level of salt intake (x ± Sx) by analyzing the different demography characteristics. The results were calculated using complex weighting by the population data from National Bureau of Statistics in 2009.</p><p><b>RESULTS</b>The intake of salt was (9.6 ± 0.3) g/d and it was higher in men ((10.4 ± 0.4) g/d) than that in women ((8.8 ± 0.3) g/d). The intake in the age group of 40-49, 50-59 and 60-69 was (9.9 ± 0.5) g/d, (10.3 ± 0.4) g/d and (9.9 ± 0.3) g/d, respectively. The adults in rural ((10.2 ± 0.3) g/d) had a higher salt intake than that of urban ((9.0 ± 0.5) g/d). An average of salt intake was increased gradually in big city ((7.9 ± 0.3) g/d), medium /small city ((9.2 ± 0.6) g/d) , general rural ((9.9 ± 0.4) g/d) and poor rural ((10.8 ± 0.7)g/d).</p><p><b>CONCLUSION</b>The mean salt intake among Chinese adults was still in a very high level.

Objective: To describe the status and trend of dietary energy, protein and fat pattern of Chinese residents. Method : 23 470 households including 68 962 subjects were randomly sampled from 132 counties in 31 provinces, autonomous regions and the municipalities. The 24 h dietary recall method for 3 consecutive days was used in dietary survey and weighing method was used for condiment intake. Results: The average energy intake per reference man per day was 9.42 MJ (2 250.5 kcal), 11.8% and 29.6% from protein and fat respectively. The percentages of energy from fat of big city residents arrived 38.4%. The percentages of energy from cereals, animal food and pure energy food were 57.9%, 12.6% and 17.3% respectively. The average protein intake per reference man per day was 65.9 g, 52%, 7.5% ,25.1% and 15.3% from cereals, bean and bean product, animal food and other foods respectively. The average fat intake per reference man per day was 76.3 g, 39.2% from animal food. Conclusion: The dietary change of Chinese residents represents the characteristics of the transition period, including the decrease of energy and protein intake per capita, decrease of the percentage of dietary energy supplied by cereals and increase of fat intake per capita,especially from animal foods, and the proportion of energy contributed by fat.
ABSTRACT
To revise Chinese Diet Balance Index (DBI) based on the current Chinese Dietary Guidelines and Food Guide Pagoda . Method: Seven food components [(cereals ,vegetables and fruits, bean and dairy , animal food , alcohol ,condiments (salt and edible oil))were selected in combination with food varieties and drinking water to build up Diet Balance Index Revision (DBI-07) .The components were weighed and assigned cut-offs and scores based on the Chinese Food Guide Pagoda. Three scoring methods (LBS-low bound score, HBS-high bound score, DQD-diet quality distance) were used to evaluate the dietary quality of 26300 adults aged 18 to 79 years from 2002 China National Nutrition and Health Survey. Results: The mean LBS, HBS and DQD were 11.5,30.0 and 41.5 respectively. About 78% adult were in moderate or severe deficit of food intake, 35.1% in moderate or severe surplus of food intake, and 43.8% in severe dietary imbalance. Conclusion: DBI-07 can reflect the principles of dietary guidelines, and the scoring method can reflect both deficit and surplus of food intake. DBI-07 can be used to evaluate the dietary quality of individual or the population.
ABSTRACT
Objective To analyze the contribution of dietary supplements to current vitamin mineral intakes in Beijing,China.Method By stratified cluster sampling method,3992 subjects aged 18y and above in 1440 households were investigated in 6 different regions in Beijing.Results The dietary intake of vitamin and mineral of men was higher than that of women,but the total intake of niacin and vitamin C was lower.Both dietary and total intake of vitamin and mineral in supplement users were higher that those in nonusers.In the group of supplement users,the contribution of supplement to thiamin,riboflavin and calcium intakes was 60% and 70%,47% and 45%,42% and 45% in men and women respectively.The percentage of supplement users who reached the current recommended intakes of vitamins and minerals was higher compared with that of nonusers,about 20 -30 percent higher for vitamin C and calcium.Conclusion The average intakes of vitamin and mineral are improved by using dietary supplements.Dietary supplements should be included in the future nutrition survey in China for improving the accuracy of nutrient’s intake.
