OBJECTIVE: Children's fruit/vegetable intake is still below recommended levels. This study applied Internet-tailored advice for schoolchildren and Internet-supported brief dietary counselling (with child and parent) within preventive health care to promote fruit/vegetable intake. SETTING/SUBJECTS: The study involved 30 seventh-grade classes (16 in the intervention group and 14 in the control group) with a total of 675 children aged 9-12 years, of whom 495 were allowed to participate. DESIGN: A cluster-randomised baseline-post-test experimental design was applied. During school hours, all children completed Internet-administered questionnaires on fruit/vegetable intake and related determinants. Children in the intervention group received immediate online individually tailored nutrition feedback. For each child in the intervention group, a nurse received information concerning the assessment of fruit/vegetable intake via the Internet to support a 5 min counselling protocol to promote fruit/vegetable intake. Children completed a similar post-test questionnaire 3 months after the first assessment. Intention-to-treat analyses were conducted using multilevel regression analyses. RESULTS: A total of 486 children (98% of 495) participated (263 in the intervention group, 223 in the control group); 240 child-parent couples in the intervention group attended the counselling. Awareness of inadequate fruit intake (odds ratio (OR) = 3.0; 95% confidence interval (CI) = 1.8-5.3) and knowledge of recommended vegetable intake levels (OR = 2.7; 95% CI = 1.8-4.1) were significantly more likely at post-test in the intervention group than in the control group. No significant effects were found on intake or other determinants. CONCLUSIONS: A compact, integrated two-component intervention can induce positive changes in knowledge and awareness of intake levels of fruit/vegetables among schoolchildren. To induce changes in intake levels, more comprehensive interventions may be needed.  相似文献

OBJECTIVE: To evaluate the effect of a primary school-based intervention providing free fruit and vegetables (F&V), separately for children of Dutch and of non-Western ethnicity. SETTING: Primary schools in two regions (west and east) in The Netherlands. DESIGN AND METHODS: Participating schoolchildren and their parents completed questionnaires at baseline and 1 year later, including questions on usual F&V intake, potential determinants and general demographics. Primary outcomes were the usual fruit intake and the usual vegetable intake as assessed by parent- and child self-reported food frequency measures. Secondary outcome measures were child- or parent-reported taste preference, knowledge of daily recommendations, availability, and accessibility for fruit intake. Multilevel regression analyses were used to assess differences at follow-up adjusted for baseline values between the control and intervention group using both child and parent reports. SUBJECTS: Five hundred and sixty-five children of Dutch ethnicity and 388 children of non-Western ethnicity (mean age 9.9 years at baseline) and their parents. RESULTS: Children of non-Western ethnicity in the intervention group reported a significantly higher vegetable intake (difference = 20.7 g day-1, 95% confidence interval (CI) = 7.6-33.7). A significant positive intervention effect was also found for fruit intake for children of Dutch ethnicity (difference = 0.23 pieces day-1, 95% CI = 0.07-0.39). No significant effects in intake were observed based on parent reports. Significant positive intervention effects were also found for perceived accessibility among children of non-Western ethnicity, as well as for parent-reported taste preference of their child among children of non-Western ethnicity and boys of Dutch ethnicity.CONCLUSION: Providing children with free F&V had some positive effects on child-reported intakes and important correlates of intakes.  相似文献

OBJECTIVE: To measure the effects of two school-based interventions on children's intake of fruit and vegetables (F&V). DESIGN AND METHODS: A total of six primary schools were randomly assigned to (1) a free F&V distribution programme, or (2) a multicomponent programme, consisting of a classroom curriculum and parental involvement. The two interventions were evaluated on their effects and compared with six control schools in a pre-test-post-test design. Two methods were used for dietary assessment: a pre-structured food recall and a food-frequency questionnaire including only F&V. SUBJECTS: A total of 939 parents of children aged 4-12 years filled out the questionnaire at both pre-test and post-test. The response rate was 54%. RESULTS: Multilevel analyses showed that both programmes were equally effective in increasing children's fruit consumption by 0.2 portions per day. The free F&V distribution increased vegetable intake among non-native children and the oldest age group, and the multicomponent programme among the oldest children and girls. The distribution also caused an increased 24 h fruit, juice and vegetable intake among the youngest and the oldest age groups, and the multicomponent programme among all children. CONCLUSION: The results of this study indicate that both interventions were shown to be effective for different subgroups regarding age, gender and ethnicity. When comparing both interventions, the distribution programme was shown to be more effective, especially in increasing vegetable consumption. An important next step will be to investigate which intervention has the greatest potential to be implemented in primary schools.  相似文献

OBJECTIVES: To identify correlates of 6th and 7th graders' (age 10-12 years) fruit and vegetable intake, to investigate parent-child correlations of fruit and vegetable intake, and to compare parents' and children's reports of children's accessibility, skills and preferences with respect to fruit and vegetables. DESIGN: The results presented are based on the baseline survey of the 'Fruits and Vegetables Make the Marks Project', where 38 schools participated. SETTING: Fruit and vegetable intake was measured by food frequency questions. Theoretical factors, based on Social Cognitive Theory, potentially correlated to intake were measured, including behavioural skills, accessibility, modelling, intention, preferences, self-efficacy and awareness of 5-a-day recommendations. SUBJECTS: In total, 1950 (participation rate 85%) 6th and 7th graders and 1647 of their parents participated. RESULTS: Overall, 34% of the variance in the pupils' reported fruit and vegetable intake was explained by the measured factors. The strongest correlates to fruit and vegetable intake were preferences and accessibility. The correlation between the children's and their parents' fruit and vegetable intake was 0.23. The parents perceived their children's accessibility to be better than what was reported by the children (P<0.01), while the children reported their skills to be better than what was perceived by their parents (P<0.01). CONCLUSION: The results from this study clearly point to a need for nutrition interventions aimed at parents. An important next step will be to investigate whether the identified correlates predict future fruit and vegetable intake, and whether they mediate any changes in intake in an intervention study.  相似文献

OBJECTIVE: To examine the contribution to fruit and vegetable eating in children of potential predictive variables within the domains of demographics, parental feeding practices and personality traits. DESIGN: Cross-sectional survey. SETTING: Questionnaires were distributed to parents through 22 London nursery schools. SUBJECTS: Questionnaires were completed and returned by 564 parents or principal caregivers of 2-6-year-old children. RESULTS: Significant predictors of children's fruit and vegetable intake emerged from all three domains examined. Demographic variables associated with child's vegetable consumption were mother's education and child's age and gender. Only ethnicity was significantly associated with fruit consumption. Parental consumption, breast-feeding and early introduction to fruit and vegetables were related to intake of both. Family meal times were associated with higher intake of vegetables, but not of fruit. Two characteristics of children themselves (food neophobia and enjoyment of food) were strongly related to the consumption of fruit and vegetables. Subsequent multivariate analyses revealed that parental intake and child food neophobia independently predicted intake of both foods. In the presence of these, fruit consumption was affected by breast-feeding and early introduction to fruit, whereas vegetable consumption was related only to child's gender and enjoyment of food. CONCLUSIONS: These findings may be used to inform future interventions aimed at increasing children's consumption of fruit and vegetables. Parents should be made aware of the possible impact of their own behaviour on the eating habits of their children.  相似文献

OBJECTIVES: To characterise the diet of First Nations in north-western Ontario, highlight foods for a lifestyle intervention and develop a quantitative food-frequency questionnaire (QFFQ). DESIGN: Cross-sectional survey using single 24 h dietary recalls. SETTING: Eight remote and semi-remote First Nations reserves in north-western Ontario. SUBJECTS: 129 First Nations (Oji-Cree and Ojibway) men and women aged between 18 and 80 years. RESULTS: The greatest contributors to energy were breads, pasta dishes and chips (contributing over 20 % to total energy intake). 'Added fats' such as butter and margarine added to breads and vegetables made up the single largest source of total fat intake (8.4 %). The largest contributors to sugar were sugar itself, soda and other sweetened beverages (contributing over 45 % combined). The mean number of servings consumed of fruits, vegetables and dairy products were much lower than recommended. The mean daily meat intake was more than twice that recommended. A 119-item QFFQ was developed including seven bread items, five soups or stews, 24 meat- or fish-based dishes, eight rice or pasta dishes, nine fruits and 14 vegetables. Frequency of consumption was assessed by eight categories ranging from 'Never or less than one time in one month' to 'two or more times a day'. CONCLUSION:We were able to highlight foods for intervention to improve dietary intake based on the major sources of energy, fat and sugar and the low consumption of fruit and vegetable items. The QFFQ is being used to evaluate a diet and lifestyle intervention in First Nations in north-western Ontario.  相似文献

OBJECTIVE: To report on the fruit, vegetable and salad intakes of Liverpool schoolchildren aged 9-10 years over a 5-year period (2000-2005). DESIGN: Cross-sectional observational study. SETTING: Between 75 and 100 Liverpool primary schools took part in each survey year. SUBJECTS: Subjects consisted of five separate cohorts of 9-10-year-old children from all areas of the city. MAIN OUTCOME MEASURES: Number and proportion of boys and girls who reported eating fruit, vegetables and salad on the previous day. RESULTS: There was an upward trend in the reported intake of fruit between 2002 and 2005. Girls were more likely than boys to report eating fruit (P < 0.001). The trend in salad intake was positive. Between 2000 and 2005 there were significant increases in the number of boys (chi2 = 17.57, P = 0.001) and girls (chi2 = 80.56, P = 0.001) eating salad. Girls were significantly more likely to eat salad than boys in all years (chi2 = 58.75, P = 0.001). Trends in vegetable intake were similar to those for salad, with both sexes reporting yearly increases over the 5-year period. The increase in the number of boys who reported eating vegetables between 2000 and 2005 was 23.5% (chi2 = 32.9, P = 0.000). In girls there was a 44.8% increase over the same period (chi2 = 110.3, P < 0.000). CONCLUSIONS: The data reveal positive trends in the fruit, vegetable and salad intakes of Liverpool schoolchildren between 2000 and 2005. Further research is needed to elucidate the specific factors that have enabled the changes to take place.  相似文献

OBJECTIVE: To evaluate the impact of a low-cost nutritional intervention in changing the lifestyle of adults. DESIGN: Randomised clinical trial. SETTING: Primary health-care centre in S?o José do Rio Preto, S?o Paulo State, Brazil. SUBJECTS: We randomly assigned 104 adults (83 women and 21 men aged 30-65 years, body mass index 24-35 kg m(-2), non-diabetic) into two groups: nutrition counselling and control. Each subject in the intervention group received three individualised nutritional counselling sessions during the first 6 months aimed at increasing intakes of fruits, vegetables and olive oil, reducing saturated fat and improving physical activity. Body composition, biochemical indicators and lifestyle were assessed at baseline and at 6 months and 1 year in both groups. RESULTS: After 6 months of follow-up, body weight, waist circumference, diastolic blood pressure, fasting blood glucose, total and low-density lipoprotein cholesterol, total and saturated fat, and dietary energy and cholesterol levels showed a more significant decrease among subjects in the intervention group than in the control group (P < 0.05). Moreover, the intervention group showed significantly greater improvement in each intervention goal, such as reduced intake of saturated fat and increased intakes of fruits, vegetables, fibre and olive oil (P < 0.05). After 12 months of follow-up, most of the outcomes were maintained. CONCLUSIONS: The low-cost nutritional intervention programme improved serum lipids profile and weight control, and appeared to be feasible for use at a primary health-care centre in a developing country.  相似文献

OBJECTIVE: To determine the difference in the nutritional status of elderly people depending on their consumption of fruits and vegetables, and to study the possible association between the consumption of these foods and different cardiovascular risk factors, especially total plasma homocysteine (t-Hcys) levels. DESIGN, SETTING AND SUBJECTS: A cross-sectional study in 152 institutionalised older people from Madrid aged > or = 65 years. Food and nutrient intakes were recorded over 7 days using the 'precise individual weighing' method. The weight, height, and waist and hip circumferences of all subjects were recorded, as were their alpha-erythrocyte glutathione reductase, serum B6, B12 and folate levels, erythrocyte folate levels, t-Hcys levels, serum lipids and blood pressure. The experimental population was then divided into tertiles depending on the serving intake of fruit and vegetables (T1, < 2.29 servings day(-1); T2, 2.29-2.79 servings day(-1); and T3, >2.79 servings day(-1)). RESULTS: Compared with T1 subjects, T3 subjects showed consumptions of cereals, pulses, meat, fish and eggs closer to those recommended (P < 0.05). In addition, the contribution of their diet towards covering the recommended daily intake of vitamin B1, niacin, vitamin B6, folic acid, vitamin C, B12, vitamin A, and P, Mg, Zn and Fe was higher. The intake of fibre increased with consumption of fruit and vegetables (r = 0.6839, P < 0.001). T3 subjects also had better serum and erythrocyte folate levels than T1 and T2 subjects (P < 0.05). A positive correlation was found between the consumption of fruit and vegetables and serum folate (r = 0.2665, P < 0.01) and with erythrocyte folate levels (r = 0.2034, P < 0.05), and a negative correlation with t-Hcys (r = -0.2493, P < 0.01). CONCLUSIONS: Greater consumption of fruit and vegetables is associated with better food habits, increased vitamin and mineral intakes and lower t-Hcys levels. Considering that the fruit and vegetable intake in Spanish elderly people is very low, it is recommended that the consumption of fruits and vegetables by elderly people be increased.  相似文献

Vitamin A status in Cuban children aged 6-11 years   总被引：1，自引：0，他引：1  
OBJECTIVE AND SETTING: A nationwide study was performed in Cuba to assess vitamin A status and the intake of vitamin-A-providing foods in children aged 6-11 years. DESIGN AND SUBJECTS: The sample comprised 1191 schoolchildren from first to sixth grade, both sexes, from municipalities randomly selected from the five eastern provinces of Cuba in 2002 (first semester) and from the four western and four central provinces in 2003 (first semester). A food-frequency questionnaire was completed by 2038 mother-and-child pairs. RESULTS: Mean (+/-standard deviation) plasma retinol concentrations were 1.77 +/- 0.48 micromol l-1 in the western, 2.01 +/- 0.56 micromol l-1 in the central and 1.40 +/- 0.41 micromol l-1 in the eastern region. No child had plasma retinol concentration below 0.35 micromol l-1, indicative of a high risk of clinical deficiency. Subclinical deficiency, plasma retinol concentration of 0.35-0.7 micromol l-1, was seen in 1.05 micromol l-1) was present in >90% of subjects in all western and central provinces, and in one of the eastern provinces (Holguín), whereas in the four remaining eastern provinces, adequate status was present in >75%. Only nine fruits and vegetables were consumed frequently (>3 times per week) by >50% of children. Thirty-seven per cent regularly consumed a supplement containing vitamin A. CONCLUSIONS: Most Cuban children aged 6-11 years had adequate vitamin A status. Consumption of foods rich in vitamin and provitamin A, especially vegetables, was frequent but limited to a small variety of foods.  相似文献

OBJECTIVES: To investigate, measure and assess the food consumption pattern of the adult population living in Beirut, Lebanon, and to identify inadequate or excessive intake of food groups particularly linked to non-communicable diseases. DESIGN: A cross-sectional food consumption survey was conducted in 2001. Dietary habits were assessed by means of a quantitative food-frequency questionnaire. SETTING: Dietary survey of the urban population (Beirut). SUBJECTS: Random sample of 444 adult subjects (aged 25-54 years) in Beirut. RESULTS: The mean consumption of food by the study population was estimated to be 3,030 g day(-1), providing an energy intake of 2,523.57 kcal day(-1). Fat contributed 38.9% to the average daily energy intake, protein 13.4% and carbohydrates 47.2%. Mean consumption of fruits and vegetables was approximately 367 g day(-1) and 45.3% of subjects consumed less than the recommended 400 g daily. Cereals contributed 324.5 g day(-1), providing 35.0% of daily energy intake, with bread being the most highly consumed (146.2 g day(-1)) in this food group. The mean intake of meat and poultry products was 91.7 g day(-1) and provided 8.8% of daily energy intake, with consumption of butchery products especially beef being the highest (47.6 g day(-1)) followed by poultry (36.1 g day(-1)). A low consumption of fish was noted (19.7 g day(-1)), with 73.6% of subjects consuming less than the recommended 2 servings of fish per week. Dairy products contributed 243.1 g day(-1) or 10.9% of daily energy intake, and milk was the least consumed dairy product (56.8% of consumers). The intake of added fats and oils, excluding those in cooked recipes, was 20.4 g day(-1); olive oil was not used in cooking but was added solely at the table and its mean intake was 5 g day(-1). The consumption of butter was low (0.86 g day(-1)) and vegetable oil was the type of fat mostly used in cooking. The average intake of alcoholic beverages was low (33.6 g day(-1)), accounting for 0.7% of total energy intake. Women had significantly higher intakes of milk, dairy products, vegetables and coffee than men (P < 0.05). The percentage of women who reported the use of low-fat items was significantly higher than that of men. Younger people (25-34 years) ate significantly more meat, sugar, alcoholic beverages and soft drinks, and consumed significantly less cooked vegetables and legumes, than older ones (P < 0.05). CONCLUSIONS: The rather high contribution of fat to daily energy intake, the low intake of fish and the relatively high percentage of people consuming less than the recommended amount of fruits and vegetables observed in this study suggest that the adult Lebanese population is at increased risk of cardiovascular diseases, obesity and other non-communicable diseases, which provides the basis for recommending increased intakes of fish, particularly fatty fish, and fruits and vegetables.  相似文献

OBJECTIVE: To assess changes in carotenoid intake based on the variations in the consumption of fresh fruit and vegetables in the Spanish population over the period 1964-2004. DESIGN: Consumption data of fresh fruit and vegetables from Family Budget Surveys carried out in 1964, 1980, 1990 and 2004. Consumption data (g per person per day) accounted for >90% of fruit and vegetable consumption at each time point. Quality controlled high-performance liquid chromatography analysis of the carotenoid composition of Spanish fruit and vegetable was used. SUBJECTS: Randomly selected, private households throughout Spain (20,800 households in 1964, 30,311 households in 1980, 21,155 households in 1990 and 6000 households in 2004). Twelve vegetables and 16 fruits representing 89-96% of the total consumption of fresh fruit and vegetables were used. RESULTS: Individual consumption of fruit and vegetables has changed over this period, altering the total and individual intake of carotenoids. Total carotenoid intake increased from 2.5 mg per person per day in 1964 to 4.1 mg per person per day in 1990, with a decrease to 3.3 mg per person per day in 2004. These increments are due to an increase in lycopene, alpha- and beta-carotene, while a decrease in lutein and zeaxanthin is observed during the last decade. A continuous and consistent decrease in the relative contribution of lutein in the diet is observed over the period studied. CONCLUSION: Although the consumption of fruit and vegetables is still consistent with a Mediterranean-type pattern, modifications in the consumption of individual fruits and vegetables have provoked changes in total and specific carotenoid intake with potential relevance in human health.  相似文献

OBJECTIVE: To examine the pattern of intake of key foods and beverages of children aged 4-12 years and the association with weight status. DESIGN AND SETTING: A computer-assisted telephone interview was used to determine the intake of fruit, vegetables, packaged snacks, fast foods and sweetened drinks 'yesterday' and 'usually' as reported by parents/guardians of a representative sample of 2184 children from the Barwon South-Western region of Victoria, Australia. RESULTS: Children who consumed >2-3, >3-4 and >4 servings of fruit juice/drinks 'yesterday' were, respectively, 1.7 (95% confidence interval (CI) 1.2-2.2), 1.7 (95% CI 1.2-2.5) and 2.1 (95% CI 1.5-2.9) times more likely to be overweight/obese compared with those who had no servings of fruit juice/drink 'yesterday', adjusted for age, gender and socio-economic status (SES). Further, children who had > or = 3 servings of soft drink 'yesterday' were 2.2 (95% CI 1.3-3.9) times more likely to be overweight/obese compared with those who had no servings of soft drink 'yesterday', adjusted for age, gender and SES. In addition, children who 'usually' drank fruit juice/drinks twice or more per day were 1.7 (95% CI 1.2-2.4) times more likely to be overweight/obese compared with those who drank these beverages once or less per week, adjusted for age, gender and SES. Although fast foods and packaged snacks were regularly eaten, there were no associations between weight status and consumption of these foods. CONCLUSIONS: Intake of sweetened beverages was associated with overweight and obesity in this population of Australian schoolchildren and should be a target for intervention programmes aimed at preventing unhealthy weight gain in children.  相似文献

OBJECTIVE: To analyse the association between socio-economic indicators and diet among 2-year-old children, by assessing the independent contribution of parental education and equivalent income to food intake. DESIGN: The analysis was based on data from a prospective birth cohort study. Information on diet was obtained using a semi-quantitative food-frequency questionnaire. Low and high intake of food was defined according to the lowest and the highest quintile of food consumption frequency, respectively. SETTING: Four German cities (Munich, Leipzig, Wesel, Bad Honnef), 1999-2001.Subjects Subjects were 2637 children at the age of 2 years, whose parents completed questionnaires gathering information on lifestyle factors, including parental socio-economic status, household consumption frequencies and children's diet. RESULTS: Both low parental education and low equivalent income were associated with a low intake of fresh fruit, cooked vegetables and olive oil, and a high intake of canned vegetables or fruit, margarine, mayonnaise and processed salad dressing in children. Children with a low intake of milk and cream, and a high intake of hardened vegetable fat, more likely had parents with lower education. Low butter intake was associated with low equivalent income only. CONCLUSIONS: These findings may be helpful for future intervention programmes with more targeted policies aiming at an improvement of children's diets.  相似文献

OBJECTIVES: To develop a concise, simple tool for use by non-specialists to assess diet in children aged 3-7 years attending primary schools. DESIGN: A 24-hour food tick list covering all aspects of the diet and with a focus on fruit and vegetable consumption was developed. This was compared against a 24-hour semi-weighed food diary obtained for the same day as the tick list. SETTING: Six primary schools with a range of socio-economic and ethnic backgrounds from a large city in the north of England (Leeds). PARTICIPANTS: One hundred and eighty children returned completed packs of information; a response rate of 77% of those who were willing to take part, 48% of those approached. RESULTS: On average, 2.4 items of fruit including juice (2.1 items as 5-a-day count) were eaten and 1.6 items of vegetables (excluding potato). Twenty-seven per cent and 36% of boys and 23% and 24% of girls reported not eating any fruit or vegetables, respectively, on the recording day. Correlations comparing the diary and tick list were high for both foods (range r=0.44 to 0.89) and nutrients (range r=0.41 to 0.68). The level of misclassification was much less than would be expected by chance. Parent and teacher evaluation of the tick list was very positive. Parents felt the tick list was easy and quick to complete. CONCLUSION: The Child and Diet Evaluation Tool (CADET) tick list has been used successfully for rapid collection of food and nutrient information from children aged 3-7 years from diverse social and ethnic backgrounds. The tool has performed better than many food-frequency questionnaires in comparison to a food diary.  相似文献

BACKGROUND: In 2001 the UK Department of Health funded pilot community-based interventions to improve fruit and vegetable intakes in five economically deprived areas of England. The effectiveness of the programme and the use of a brief tool for evaluating community interventions are reported here. METHODS: Data on intakes of and beliefs about fruit and vegetables were collected by a short postal questionnaire (FACET--Five-a-day Community Evaluation Tool) simultaneously from 810 individuals living in the pilot communities and 270 individuals who were participating in an unrelated observational study (controls). Data were collected before and after a 12-month intervention period. Quantitative dietary data derived from 7-day food diaries available for control subjects were used to assess the ability of the FACET questionnaire to estimate fruit and vegetable intakes. RESULTS: Compared with controls, the intervention group significantly increased their knowledge of the 5-a-day optimum (P<0.01) and reported increased access to fruits and vegetables (P<0.001). Overall, the intervention had no demonstrable effect on total fruit and vegetable intakes as measured by FACET. However, smoking habit strongly predicted change in fruit and vegetable intakes (P<0.01) in the intervention group. Opposite trends were observed in the two groups, with 'smokers' and 'non-smokers' in the intervention and control groups respectively reducing their fruit and vegetable intakes. The FACET questionnaire agreed with food diary estimates of fruit and vegetable intakes in 56% of cases. CONCLUSIONS: Community-based interventions can produce important changes in knowledge of and access to fruit and vegetables. However, in this study change in fruit and vegetable intakes was strongly influenced by smoking habit. This bias needs to be considered in planning future intervention and evaluation programmes. The FACET questionnaire provides acceptable estimates of fruit and vegetable intakes which may be used for grading intake in large community-based projects.  相似文献

OBJECTIVE: To compare the anthropometric, alimentary, nutritional and lipid profiles and global diet quality of Spanish children according to saturated fat intake. DESIGN: This was a cross-sectional study. Food data were collected using a food-frequency questionnaire. SUBJECTS AND METHODS: The sample included 1112 children of both sexes, aged between 6 and 7 years, selected by means of random cluster sampling in schools. The plasma lipid profile included measurements of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, apolipoprotein A1 (apoA1) and apolipoprotein B (apoB). Global diet quality was evaluated by the Dietary Variety Index (DVI) and the Healthy Eating Index (HEI). RESULTS: Energy intake, DVI and HEI of children from the lower quartile of saturated fat intake (LL) were higher (P<001) than in the remaining children (UL). However, there were no significant differences in average height or weight between groups. The UL children had lower intakes of meat, fish, vegetables, fruits and olive oil and a higher intake of dairy products (P<0.001). The intakes of fibre, vitamins C, D, B6, E and folic acid were higher in the LL children, who had lower intakes of vitamin A and calcium. The ratios LDL-C/HDL-C and apoB/apoA1 were lower (P=0.04) in the LL children (1.87 and 0.52, respectively) than in the UL children (2.02 and 0.54, respectively). CONCLUSIONS: The growth rate of children does not seem to be affected by the level of saturated fat intake. Furthermore, at the levels of intake observed in this study, diets with less saturated fat are associated with better alimentary, nutritional and plasma lipid profiles.  相似文献

OBJECTIVE: This study examines parental report of household food availability, parent dietary intake and associations with adolescent intakes of fruits, vegetables and dairy foods. DESIGN: Cross-sectional study. Adolescents completed the Project EAT survey and the Youth Adolescent Food Frequency Questionnaire at school. Parents of adolescents were interviewed by telephone about the home food environment, eating habits and weight-related behaviours. General linear modelling was used to compare dietary intakes of adolescents across different levels of household food availability and parental intakes. SUBJECTS/SETTING: The study sample included 902 adolescents and their parent or guardian. RESULTS: Many parents were not consuming the minimum number of daily recommended fruit (44.5%), vegetable (69.9%) or dairy (46.9%) servings. While most parents reported that fruits and vegetables were available at home (90.3%) and vegetables were usually served at dinner (87.0%), fewer parents reported milk was served at meals (66.6%). Soft drinks were usually available at home (56.8%). Among girls, household availability was positively associated with fruit and vegetable intake (ttrend=2.70, P<0.01) and soft drink availability was inversely associated with dairy intake (ttrend=2.08, P=0.04). Among boys, serving milk at meals was positively associated with dairy intake (ttrend=3.65, P<0.01). Parental intakes were positively associated with dairy intake for boys (ttrend=2.04, P=0.04), and with dairy (ttrend=2.43, P=0.01), vegetable (ttrend=3.72, P<0.01) and fruit (ttrend=3.17, P<0.01) intakes for girls. CONCLUSIONS/APPLICATIONS: Interventions designed to help adolescents improve consumption of fruits, vegetables and dairy foods may be enhanced by including a parental component aimed at increasing household availability and parents' intake of healthful food choices.  相似文献

OBJECTIVE: To assess the effectiveness of a behaviour change approach, with or without financial support, in improving vitamin A (VA) intake and serum retinol concentration through mango and liver consumption by children. DESIGN: A parallel design (no control area) was used to assess changes in VA intake and serum retinol over a 15-week period. SETTING AND SUBJECTS: A pilot study was implemented in the Department of Kokologho, a rural area in central west Burkina Faso. One hundred and fifty children aged 2-3 years were randomly selected and assigned to two treatment groups: PA$$ (promotional activities and financial support) and PA (promotional activities). RESULTS: The intervention significantly increased (P < 0.001) total VA intake by 56% in PA$$ and by 50% in PA. VA intake from liver increased significantly (P < 0.001) from 12.7 +/- 23.5 to 155.3 +/- 56.3 microg retinol activity equivalents (RAE) in PA$$ and from 21.6 +/- 29.7 to 135.3 +/- 44.9 microg RAE in PA. Changes in VA intake from liver were significantly higher (P = 0.004) in PA$$ compared with PA. Mean serum retinol concentration increased significantly by 26% (P < 0.001) in PA$$ and 30% (P < 0.001) in PA. Changes in serum retinol concentration (0.13 micromol l(-1) in PA$$ vs. 0.17 micromol l(-1) and in PA) did not differ significantly (P = 0.455) between groups over the intervention. CONCLUSION: Promotional activities on mango and liver intake effectively increased VA intake and serum retinol concentrations. Although an additional beneficial effect of financial support on liver intake was observed, this did not translate into a further increase in serum retinol concentration.  相似文献
