ABSTRACT

Objective@#To evaluate the dietary quality of residents in Wenzhou City, Zhejiang Province, so as to provide the basis for future health education and nutrition intervention programs.@*Methods@#A stratified multi-stage random sampling method was used to select residents aged 18 years and older in 6 counties (cities, districts) of Wenzhou City as the study subjects, “24-hour dietary review for 3 consecutive days” was adopted to collect dietary intake, and the diet balance index (DBI_16) scoring method was applied to evaluate the dietary quality.@*Results@#This study analyzed the dietary quality of 406 residents in Wenzhou City, including 197 males (48.52%) and 209 females (51.48%). The majority of the residents were aged 18-44 years (254 residents, 62.56%). The median DBI total score was -31 (interquartile range, 8), and 404 residents had insufficient dietary intake, accounting for 99.51%. The median DBI positive score was 5 (interquartile range, 6), and 288 residents had appropriate dietary intake, accounting for 70.94%. The median DBI negative score was 37 (interquartile range, 6), and 210 residents had a high level of insufficient dietary intake, accounting for 51.72%. Five dietary patterns, namely A, B, C, E and F, were identified, with pattern B being the most dominant, accounting for 75.62% of the total (307 individuals). Patterns D, H, I and G were not observed.@*Conclusions@#The dietary quality of the residents surveyed indicates the existence of dietary imbalances, mainly manifesting as inadequate intake. It is recommended to strengthen nutritional and health guidance.

ABSTRACT

【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.

ABSTRACT

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.

ABSTRACT

【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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Objective To examine the relationship between the duration of diet and the risk related to excess body weight in residents of Nanjing city.Methods With multi-stage cluster random sampling method,a total number of 3376 local residents aged 30 and over in 7 communities from 2 urban districts were involved in this survey.Through diet balance index (DBI),nine dietary patterns were identified.Subjects with normal BMI in the baseline survey were selected to participate in the follow-up survey.Multiple linear regression and multivariate logistic regression analysis were used to estimate the incidence risks on overweight and obesity.Results Of 1898 eligible subjects with normal BMI in the baseline survey,1347 of them completed the 3-year follow-up survey,with a follow-up rate of 71.0%.By multiple linear regression method,on average,an increase in DBI_DQD of 1 unit was seen and associated with a 0.028 increase in BMI.DBI_DQD were also associated with BMI (β=0.022,P<0.001)after adjusted for the covariates.By logistic regression,when compared with the group of healthy dietary pattern,the relative risk for excessive body weight was 1.37 for those with unhealthy dietary patterns.After adjusting the possible confounding factors,the excessive body weight was also associated with significantly increased risk (RR=1.51,95% CI:1.09-2.09).Conclusion Results from this study provided evidence,showing that unhealthy dietary patterns could predict the increase risk of excessive body weight,suggesting that healthy dietary pattern was important in controlling the excessive body weight.

ABSTRACT

Objective To evaluate the effect of a community-based nutrition education program on the dietary quality of the elderly with diet balance index(DBI). Methods Eighty-three volunteers from Zhujing Town of Jinshan District of Shanghai with age ≥60 years were served as study objectives,and a total of 70 people completed the program.They were given nutritional guidance bimonthly in combination with measures such as community publications,panel discussions and individual interviews.Measurements of dietary intakes,which lasted for 3 d, were performed before intervention and 12 months after intervention,respectively.Diet quality was evaluated with DBI scoring system,and the parameters were compared before and after intervention. Results There were significant differences in DBI-Total Score(DBI-TS),DBI-Lower Bound Score(DBI-LBS)and DBI-Diet Quality Distance(DBI-DQD)before and after intervention for these 70 people (P<0.05).The proportion of subjects with adequate milk and soy product consumption increased from 7.1% before intervention to 20.0% after intervention,that with proper amount of salt intake from 22.9%to 51.5%.and that with diverse diet from 20.0%to 49.9%.The major DBI pattern changed from pattern B (47.1%) and pattern E(34.3%)to pattern B (34.3%) and pattern A (32.9%). Conclusion The community-based nutrition education program for the elderly can improve the diet quality of the elderly.
