Association between dietary quality and bone mass among middle-aged and elderly people in Gansu Province / 西安交通大学学报(医学版)

【Objective】 To evaluate the dietary quality with the dietary balance index (DBI_16) and the association between dietary quality and bone mass among middle-aged and elderly people in Gansu Province so as to provide evidence for improving dietary quality and bone health status of Gansu population. 【Methods】 Based on the information of the type and quantity of food intake and the bone mass of middle-aged and elderly people aged 35 years and above collected by the Gansu Project in the Regional Ethnic Cohort Study in Northwest China, DBI_16 was used to evaluate the intake level of cereals, vegetables, fruits, milk, beans, fish and shrimp, eggs and other foods, and the degree of inadequate, excessive and unbalanced dietary intake of the participants. Multiple linear regression was used to evaluate the associations of three component indexes of DBI_16, high bound score (DBI_HBS), low bound score (DBI_LBS), diet quality distance (DBI_DQD), and seven single indexes of DBI_16 with bone mass. 【Results】 Analyses of the dietary and bone mass data of 11,840 participants showed that 44.8% of participants consumed excessive amounts of cereals compared to the dietary recommendation. 96.3%, 90.6%, 90.1%, 71.9%, 95.1% and 60.3% of participants’ intake of vegetables, fruits, milk, soybeans, fish and shrimp, and eggs, respectively, were inadequate. 47.7% participants consumed less than 10 types of food. 2.3% participants’ DBI_LBS levels were appropriate. 54.7% participants’ DBI_HBS levels were appropriate. Only 1.2% participants’ DBI_DQD reached a balanced level. The bone mass level in the study population was (2.5±0.6) kg [(2.8±0.5) kg for men and (2.3±0.5) kg for women]. After adjusting for sociodemographic characteristics, lifestyle, total dietary energy intake and body mass index, DBI_LBS and DBI_DQD were negatively associated with bone mass [β and 95% CI was -0.002 01 (-0.003 62--0.000 40) and -0.001 76 (-0.003 09--0.000 43), respectively]. 【Conclusion】 Dietary intake imbalance is common among middle-aged and elderly people in Gansu Province, and the more severe the dietary intake imbalance, the lower the bone mass level.

Evaluation of diet quality among pregnant women in Shaanxi Province by Diet Balance Index for Pregnancy / 西安交通大学学报(医学版)

【Objective】 To evaluate the diet quality of pregnant women in Shaanxi Province by Diet Balance Index for Pregnancy (DBI_P) and investigate the influencing factors. 【Methods】 By using a multi-stage stratified random sampling method, 7375 pregnant women in 30 districts (counties) of Shaanxi Province were recruited. A structured questionnaire was adopted to collect general information in pregnancy, and a semi-quantitative food frequency questionnaire was used to obtain dietary information in pregnancy. DBI_ P was used to evaluate the diet quality during pregnancy, and the factors influencing diet quality were assessed by multiple linear regression. 【Results】 More than 50% pregnant women had inadequate intakes of dairy products, fish and shrimp, meat and poultry, vegetables, eggs, fruits and diet variety. More than 69% pregnant women had excessive intakes of cooking oil, cereals and salt. The average values of high bound score, low bound score, and diet quality distance were 12.9, 19.5, and 32.5, respectively. The proportions of medium inadequate, excessive, and imbalance of dietary intakes were 20.3%, 22.55%, and 40.8%, respectively. DBI_LBS during pregnancy was negatively correlated with childbearing age, education level, family per capita annual income, antenatal examination frequency and folic acid supplementation, but positively correlated with living in southern and northern Shaanxi, residing in rural areas, being farmers, and drinking alcohol. DBI_HBS during pregnancy was negatively correlated with living in southern and northern Shaanxi, but positively correlated with active/passive smoking and drinking strong tea. DBI_DQD during pregnancy was negatively correlated with education level, family per capita annual income, antenatal examination frequency and folic acid supplementation, but positively correlated with living in southern Shaanxi, residing in rural areas, being farmers, parity, active/passive smoking, and drinking strong tea and coffee. 【Conclusion】 The dietary intake of pregnant women in Shaanxi Province was insufficient and unbalanced, and the dietary quality was affected by sociodemographic and life behavior factors during pregnancy. Nutritional intervention measures should be targeted.

Evaluation on the dietary quality of patients with Type 2 diabetes mellitus in the community by adjusted Chinese diet balance index / 中华健康管理学杂志

Objective:To evaluate the diet quality of patients with Type 2 diabetes mellitus (T2DM) in the community with the Chinese Dietary Balance Index (DBI-16) and to provide a scientific basis for nutrition education.Methods:A random cluster sampling method was adopted to conduct a questionnaire survey of 332 T2DM patients in a community of Bengbu City to obtain demographic sociology and dietary intake information. DBI-16 was used to score and evaluate dietary structure and diet quality.Results:There are low-level under-intake (low bound score =14.0) and excessive intake (high bound score =14.0) in the diet of this population. The degree of excessive intake of men (high bound score =15.0) was higher than that of women (high bound score=13.0) ( Z=-3.12, P<0.01), and the degree of insufficient diet (low bound score =13.0) was lower than that of women (low bound score=15.5)( Z=-2.05, P<0.05). Those with monthly income<1 000 (low bound score =15.5) patients ( χ2 =6.34, P<0.05) and disease course>10 years (low bound score =16.0) had the highest degree of insufficient dietary intake ( χ2 =9.40, P<0.01). Those who did not participate in community health education lectures had significantly higher dietary intake (low bound score =15.0) and imbalance (diet quality distance= 29.0) than those who participated in community health education (low bound score=13.0)(diet quality distance=27.0)( Z=-2.46, P<0.01). According to the score distribution of the DBI-16 index, 73.6% of patients had a severe over-intake of cereals, and only 27.4% and 27.7% had intake of vegetables, fruits, and milk beans that reached the recommended intake. The dietary pattern mainly reflects the existence of a certain degree of excessive dietary intake pattern D. Conclusion:The dietary quality of T2DM patients in Bengbu′s community is in a state of low imbalance. Insufficient and excessive dietary intake coexist and urgently need to be improved.

Evaluation of the dietary quality of De'ang nationality residents over 18 years old in Yunnan by Diet Balance Index DBI_16 / 公共卫生与预防医学

Objective To evaluate the dietary quality of De'ang nationality residents over 18 years old in Yunnan Provinceusing the new adjusted Diet Balance Index (DBI_16), and to provide scientific basis for improving the nutritional status of De'ang residents and formulating health promotion strategies. Methods A food-frequency questionnaire was used to investigate the diet of De'ang residents, and the new adjusted dietary balance index (DBI_16) was used to evaluate the dietary quality. Results The dietary quality of De'ang nationality residents over 18 years old in Yunnan Province was in a moderately imbalanced state (DQD=42), and the main problem was insufficient dietary intake (LBS = 26). The dietary imbalance among men, 65-79 years old and low-income people was serious. The intake of milk, vegetables, fruits and aquatic products was the most insufficient and people who met the recommended intake levels of these foods were 2%, 34.7%, 31.8%, and 36%, respectively. Meanwhile, there existed the problem of excessive intakes among people studied in the present investigation. Pople who consumed more than recommended amount of Cereal food, livestock and poultry meat, and edible oil accounted for 76.9%, 60.4% and 63.5%, respectively. Conclusion The dietary structure of De'ang residents over 18 years old in Yunnan Province is unreasonable. The problems of both insufficient and excessive dietary intakes exist. Education on balance diet should be conducted to improve nutrition and health status of De'ang nationality residents.

Using the revised Chinese diet balance index Quality of Diet to evaluate the quality of diet among rural residents in Hanzhong,Shaanxi province and relative influencing factors / 中华流行病学杂志

Objective To evaluate the quality of diet among rural residents in Hanzhong, Shaanxi province and to investigate the relative factors. Methods A cross-sectional survey on dietary status together with a semi-quantitative food frequency questionnaire were conducted among rural residents aged between 18 and 80 in Hanzhong of Shaanxi,in 2010. Quality of diet was evaluated by using DBI-07 scoring and evaluating system. Linear regression models were developed to identify factors related to under or over intakes. Results 2 241 rural residents were under study. 65%of the residents’daily intake of grains,oil and salt exceeded the RNI while animal food,diary food,eggs, vegetables and fruits were under,to some extent. The average values of DBI_LBS and DBI_HBS were 24.83 and 5.70. The proportions of moderate under-intake (25≤DBI_LBS≤36) and moderate over-intake(14≤DBI_HBS≤19)were 33.4%and 51.0%. Factors as family number,education level, fortune index,physical activity,higher labor intensity seemed to be protective for dietary under intake (P<0.05). Moderate fortune index,drinking alcohol(more than once a week),being male,age and smoking status(>15 cigarettes per day)were risk factors for over-intake of diet(P<0.05). Factors as larger family size and having had education above the levels senior school were significantly and negatively associated with the over-intake of diet (P<0.05). Conclusion The main diet problem among the rural residents was related to under-intaken but over-intake did exist to some extents. Our study results called for specific intervention in improving the quality of diet among the residents in Hanzhong.
