ABSTRACT
Objective@#In this study, a systematic review was made on scientific evidence regarding the impact of food environment on diet-related behavior and obesity in China.@*Methods@#Search on related keywords and references were conducted from four electronic databases including the Cochrane Library, PubMed, Web of Science, and CNKI.@*Results@#Data showed that good availability, accessibility of neighborhood food outlets had increased the diversity of food, including the intakes of total calories, protein, fat, and carbohydrate; however, the consumption of healthy foods such as fruit and vegetables was reducing among the Chinese residents. The effects of neighborhood food environment on obesity remained inconclusive. A large number of fast food restaurants around schools might be responsible for the increase of risk on obesity among students. Regulations set on the school vicinity food stalls might reduce the intake of sugary beverages, snacks and fast food among students.@*Conclusion@#Building a healthy food environment is warranted to nudge the Chinese people towards a healthier diet pattern. However, more evidence is needed to support the evidence in building a healthy food environment.
ABSTRACT
Objective@#To investigate the comprehensive nutritional status and diet behavior of middle aged and elderly women with osteoporosis, and thereby to explore the relationship between diet behavior and comprehensive nutritional status.@*Methods@#311 middle-aged and elderly women with osteoporosis in Chengdu were included in this study. Mini Nutritional Assessment (MNA) was applied to assess their comprehensive nutritional status. Information of social-demographic characteristics and diet behavior (about meals, snacks and water drinking, etc.) of the subjects was collected by questionnaire. Chi square test was used to assess the differences in nutritional status among patients who have different eating behaviors. Logistic regression analysis was performed to evaluate the relationship between diet behaviors and comprehensive nutritional status.@*Results@#The mean MNA score of subjects was 25.8±2.5. 20.3% (63/311) of the subjets were at risk of potential malnutrition, but there was no malnourished subjects found. 46.9% (46/311) of the subjects were in good appetite. 95.2% (296/311) of them had a fixed food intake each meal. 65.8% (198/311) of them had snacks every day, and the most common choice was fruit (86.4% (248/287)). 54.8% (165/311) of them had initiative drinking water habits, and the most common choice was plain boiled water (79.9%, 246/308). 76.5% (238/311) of them had daily portable water less than 1 500 ml. After adjusting the effects of age, occupation and education level, bad appetite (OR=3.50, 95%CI: 1.18-10.62), unfixed food intake (OR=7.27, 95%CI: 1.40-35.83), and seldom or never intake of snack (OR=3.71, 95%CI: 1.42-9.72) were risk factors for malnutrition risk, while tea drinking was protective factor(OR=0.31, 95%CI: 0.11-0.93).@*Conclusion@#Risk of potential malnutrition and unhealthy diet behavior among the middle aged and elderly women with osteoporosis should be paid more attention. Unhealtghy diet behavior has a negative effect on their comprehensive nutritional status.
ABSTRACT
O termo estereótipo designa algumas percepções generalizadas que determinados grupos atribuem a um indivíduo, a grupos, objetos e/ou eventos. Objetivo: O objetivo do estudo foi avaliar as prioridades que nutricionistas e triatletas atribuem aos alimentos, visando à aquisição de um melhor desempenho esportivo. Método: A amostra foi composta por 56 sujeitos, divididos em dois grupos: Nutricionistas (G1, n = 29) e Triatletas (G2, n = 27). O Questionário de Prioridade Alimentar (QPA), composto por grupos alimentares, foi utilizado para avaliar a importância atribuída a cada alimento para o desempenho atlético. Resultados: Para a análise dos dados, cada alimento foi agrupado em uma das oito categorias da pirâmide alimentar. Foram elaboradas médias aritméticas para as categoriais e realizados testes t para amostras independentes para comparar as prioridades de nutricionistas e triatletas em relação às mesmas. Não foram encontradas diferenças significativas em relação às categorias Hortaliças, Leguminosas, Frutas e Açucares/Doces e, também, para o item café preto. Entretanto, Cereais/Pães/Tubérculos e Carnes/Ovos foram superestimados pelos triatletas enquanto os Leites/Produtos Lácteos e Óleos/Gorduras foram subvalorizados. Conclusão: Os triatletas supervalorizam alguns macronutrientes (carboidratos e proteínas) em detrimento de outros, como os lipídeos.
Stereotype is a term designated to some generalized perceptions that people attribute to another individual, groups, objects and/or events. Objective: The purpose of this study was to evaluate the priorities that nutritionist and triathletes attributed to food to enhance the sport performance. Method: The sample was composed by 56 subjects, splited in two groups: Nutritionists (G1, n = 29) and Triathletes (G2, n = 27). The Intake Food Priority Questionnaire (QPA), composed by food groups, was used to evaluate the importance of each food in the athletic performance. Results: To the data analysis, each food was grouped into one of the eight categories designed in nutrition pyramid. An arithmetic means were elaborated to categories and it was performed t tests for independent samples to compare nutritionists and triathletes priorities about each category. There were no differences between groups in Vegetables, Leguminous, Fruits and Sugar/Candies categories and, also, to the black coffee item. However, the triathletes overestimated the Cereals/Breads/Tubercle and Meat/Eggs categories and underestimated the Milk/Dairy Products and Oils/Fat categories. Conclusion: The triathletes overestimated some macronutrients (carbohydrates and proteins) in detriment from another, like lipids.
ABSTRACT
This study was designed to evaluate the effect of individualized diabetes nutrition education. The nutrition education program was open to all type 2 diabetes patients visiting the clinic center and finally 67 patients agreed to join the program. To compare with 67 education group subjects, 34 subjects were selected by medical record review. The education program consisted of one class session for 1-2 hours long in a small group of 4~5 patients. A meal planning using the food exchange system was provided according to the diet prescription and food habits of each subject. Measurements of clinical outcomes and dietary intakes were performed at baseline and 3 months after the education session. After 3 months, subjects in education group showed improvement in dietary behavior and food exchange knowledge. In education group, intakes of protein, calcium, phosphorus, vitamin B2, and folate per 1,000 kcal/day were significantly increased and cholesterol intake was significantly decreased. They also showed significant reductions in body weight, body mass index (BMI), and fasting blood concentrations of glucose (FBS), HbA1c, total cholesterol, and triglyceride. However, no such improvements were observed in control group. To evaluate telephone consultation effect, after the nutrition education session, 34 subjects of the 67 education group received telephone follow-up consultation once a month for 3 months. The others (33 subjects) had no further contact after the nutrition education session. Subjects in the telephone follow-up group showed a decrease in BMI, FBS, and HbA1c. Moreover, the subjects who did not receive telephone follow-up also showed significant decreases in BMI and FBS. These results indicated that our individually planned education program for one session was effective in rectifying dietary behavior problems and improving food exchange knowledge, and quality of diet, leading to an improvement in the clinical outcomes. In conclusion, our individualized nutrition education was effective in adherence to diet recommendation and in improving glycemic control and lipid concentrations, while follow-up by telephone helped to encourage the adherence to diet prescription.
