[Dietary microelements intakes status of elderly people from different areas in Zhejiang Province in 2010-2012].

OBJECTIVE: To assess the situations of dietary microelements intakes among elderly people in different areas of Zhejiang Province, and analyze the food sources of microelements. METHODS: Data were obtained from the 2010-2012 Chinese National Nutrition and Health Survey in Zhejiang Province. 832 elderly people( 434 male, 398 female, age was( 68. 02±6. 68) years) were from large cities, small-medium cities and rural counties. The 24-hour dietary recall method for 3 consecutive days was used to collect food intake information to analyze dietary intakes among elderly people of Fe, Mn, Cu, Zn, Se and their sources in different areas. RESULTS: The elderly people'intakes of Mn was 4. 86( 3. 44, 6. 45) mg/d, Cu was 1. 69( 1. 13, 2. 27) mg/d, and Se was36. 85( 21. 32, 54. 21) µg/d, those were generally low. The intake of Zn was 10. 15( 7. 94, 12. 62) mg/d in males, was low as well. Intakes of Mn, Cu, Se were significantly different in different areas, small-medium cities had highest intakes of Mn( 5. 87 mg/d)and Cu( 1. 88 mg/d), large cities had a highest intake of Se( 45. 47 µg/d). The food sources of microelements were slightly variant. Rural counties had less fungi and algae sources of Fe and Mn than large cities and small-medium cities. The Cu from vegetables were higher than dried legumes and the Se from poultry and poultry products were higher than eggs in rural counties. The Zn from fish, shellfish and mollusk were higher than dried legumes in large cities. CONCLUSION: The insufficient status of microelements intakes among elderly people in Zhejiang Province was serious, and there were differences among elderly people from different areas in intakes and food sources of microelements.

[Comparative study on burden of diet-related chronic diseases in China between 1990 and 2016].

OBJECTIVE: To compare the disease burden of diet-related chronic diseases in China between 1990 and 2016. METHODS: Based on the Global Burden of Disease 2016, we extracted the absolute number of deaths and disability-adjusted life years( DALYs) of diet-related chronic diseases and the corresponding age-standardized rates in China in 1990 and 2016. Subgroup analyses were conducted in various gender, dietary risk factors and categories of diseases. RESULTS: In 2016, the total number and rate of diet-related NCDs deaths was 2493 thousand and 182. 4/100000. The corresponding number and rate of DALYs was 54995 thousand person-year and 4023. 0/100000. Compared with those in 1990, the rates of death and DALYs in 2016 increased by19. 5% and 9. 3%, respectively. Both death rate and DALYs rate increased with the age. Death rate( 214. 6/100000) and DALYs rate( 4961. 1/100000) in males were 1. 4-fold and 1. 6-fold as that in females( 148. 2/100000 and 3028. 2/100000, respectively). High intake in sodium, low intake in whole grains and low intake in fruits were the three leading dietary risk factors and cardiovascular diseases accounted for 88. 1% DALYs in all chronic diseases. CONCLUSION: The burden of diet-related chronic diseases in China is severe and it continues increasing over years.

[Analysis on the dietary survey results of 60 years old and over population in different economic area of Zhejiang Province in 2010-2012].

OBJECTIVE: To analyze the dietary energy and pattern of the elderly in different economic area of Zhejiang Province. METHODS: Data was from Chinese National Nutrition and Health Survey from 2010 to 2012 in Zhejiang Province. The 24 h dietary recall method for 3 consecutive days was used in dietary survey and weighing method was used for condiment intake. RESULTS: There were 793 elderly( age≥60 years) attended in the survey. The intake of beans and nuts, fish and shrimps, eggs, cereals and vegetables respectively were 30. 26, 54. 07, 20. 56, 300. 27 and 277. 78 g. The livestock and poultry meat( 92. 69 g), salt( 9. 14 g), and cooking oil( 33. 60 g) intake was higher than that recommended. Dietary pattern of the urban was better than that of the rural areas. The proportion of energy providing in protein and fat was 14. 17% and 34. 46%, respectively. The proportion of protein from grain and animal food was 31. 51% and 37. 48%. The proportion of fat from plant food was 66. 44%. CONCLUSION: The major problems areirregular diet, imbalanced diet, and unreasonable food sources of protein in Zhejiang province. Because the level of each localities economic development is different, each region's dietary problems are different. We need to research in different areas to analyze specific issues of nutrition interventions, and improving the elders' life quality.

Dietary intake of manganese and the risk of the metabolic syndrome in a Chinese population.

Animal studies have suggested that Mn might be associated with some components of the metabolic syndrome (MetS). A few epidemiological studies have assessed dietary Mn intake and its association with the risk of the MetS and its components among Chinese adults. In this study, we assessed daily dietary Mn intake and its relationship with MetS risk among Chinese adults in Zhejiang Province using data from the 5th Chinese National Nutrition and Health Survey (2010-2012). A total of 2111 adults were included. Dietary Mn intake was assessed using 3-d 24-h dietary recalls; health-related data were obtained by questionnaire surveys, physical examinations and laboratory assessments. The mean intake of Mn was 6·07 (sd 2·94) mg/d for men (n 998) and 5·13 (sd 2·65) mg/d for women (n 1113). Rice (>42 %) was the main food source of Mn. The prevalence of the MetS was 28·0 % (590/2111). Higher Mn intake was associated with a decreased risk of the MetS in men (Q4 v. Q1 OR 0·62; 95 % CI 0·42, 0·92; P trend=0·043) but an increased risk in women (Q4 v. Q1 OR 1·56; 95 % CI 1·02, 2·45; P trend=0·078). In addition, Mn intake was inversely associated with abdominal obesity (P trend=0·016) and hypertriacylglycerolaemia (P trend=0·029) in men, but positively associated with low HDL-cholesterol in both men (P trend=0·003) and women (P trend<0·001). Our results suggest that higher Mn intakes may be protective against the MetS in men. The inverse association between Mn intake and the MetS in women might be due to the increased risk for low HDL-cholesterol.

[Dietary protein intake status of urban residents in Zhejiang province].

OBJECTIVE: To analysis the status of dietary protein intake of urban residents in Zhejiang Province. METHODS: Dietary nutrients intake was estimated using the method of 3 day 24-hour dietary recall and food weighted record, 3452 residents who above 2-year-older were recruited in 2009 - 2011, and calculating the daily intake of food, protein and amino acid, analyzing the protein intake combined with demographic information. RESULTS: 3240 residents were included in this analysis, the residents with protein intake lower than 80% of the RNI accounted for 34.3%. The average protein intake in per day was 71.1 g for per reference man, the supply of high-quality protein accounted for 51.7% of the protein. All ratio coefficients of essential amino acids were close to 1 and the amino acid score was equal to 85. The proportion that protein intake was equal or greater than RNA enhanced as the degree of education improved( OR = 0.822, P < 0.001). CONCLUSION: Dietary protein intake of urban residents in Zhejiang Province was among reasonable ranges, the proportion of high-quality protein was appropriate, and the amino acid pattern was similar to the pattern recommended by WHO/FAO, the nutrition value of dietary proteins was high. The protein intake enhanced as the degree of education improved. Urban residents of Zhejiang Province had the risk of inadequate dietary protein, older men and women of childbearing age were the most prominent.
