OBJECTIVE: To determine changes in reported food frequency in adults between 1986 and 1999. DESIGN: Four consecutive cross-sectional surveys. SETTING: Counties of Norrbotten and V?sterbotten, Northern Sweden. SUBJECTS: The Northern Sweden MONICA (Monitoring of Trends and Determinants in Cardiovascular Disease) population, four independent cross-sectional surveys in 1986, 1990, 1994 and 1999. Randomly selected age-stratified samples of the population aged 25-64 years. Analysis is based on 2982 males and 3087 females who completed an 84-item food-frequency questionnaire. RESULTS: Between 1986 and 1999, average reported consumption of 3%-fat milk decreased from 42 to 7 intakes month(-1) in men and from 28 to 4 intakes month(-1) in women. Reported use of 1.5%-fat milk increased from 6 to 27 intakes month(-1) in men and from 6 to 24 in women. Monthly intakes of potatoes and root vegetables decreased from 38 to 27 in men and from 39 to 32 in women. Consumption of pasta increased from 4 to 7 intakes month(-1) in both sexes. Intakes of solid fats with 80% fat content dropped from 92 to 62 per month in men and from 78 to 52 per month in women, whereas use of 40%-fat spread increased from 12 to 22 intakes month(-1) in men and from 5 to 26 in women. Monthly intakes of vegetable oil increased from 3 to 12 in men and from 3 to 15 in women. The percentage of overweight or obese individuals (body mass index >25 kg m(-2)) increased from 52 to 65% in men and from 41 to 52% in women (P for linear trend in all these changes, <0.001). CONCLUSIONS: Our data indicate reduced consumption of foods with a high content of saturated fats. In spite of that, there is an unbroken trend towards increased obesity.  相似文献

OBJECTIVE: To examine educational differences among people who consume foods containing fat in Finland and the Baltic countries. DESIGN: Data were collected from cross-sectional postal Finbalt Health Monitor surveys that were carried out in 1998, 2000 and 2002. SETTING: Estonia, Finland, Latvia and Lithuania. SUBJECTS: For each survey, nationally representative random samples of adults aged 20-64 years were drawn from population registers (Estonia, n = 3656; Finland, n = 9354, Latvia, n = 6015; Lithuania, n = 5944). RESULTS: Differences were revealed between the countries in the consumption of foods that contain fat. Finnish people consumed butter on bread, high-fat milk, meat and meat products, and vegetable oil for cooking less frequently than people in the Baltic countries. Cheese was most popular in Finland. Educational differences in fat-related food habits were examined by applying logistic regression analysis. A positive association was found between level of education and consumption of vegetable oil used in food preparation. Drinking high-fat milk was associated with low education in all countries. People with higher education tended to consume cheese more often. Educational patterns in the consumption of butter on bread and in the consumption of meat and meat products differed between countries. CONCLUSIONS: The consumption of foods containing fat was related to educational levels in all four countries. The diet of better-educated people was closer to recommendations for the consumption of saturated and unsaturated fats than the diet of people with lower level of education. The educational gradient was more consistent in Finland than in the Baltic countries. These existing educational differences in sources of fat consumed should be taken into account in the development of national cardiovascular disease prevention programmes.  相似文献

OBJECTIVE: To assess whether the Mediterranean diet contributes to overall mortality differences and trends between Mediterranean and non-Mediterranean European Union (EU) countries.Design: Routinely recorded adjusted overall mortality and food availability data in Mediterranean and non-Mediterranean EU countries. A Mediterranean diet score designed a priori was used as instrument. SETTING: Fifteen EU countries in the 1960s and the 1990s. SUBJECTS: The general population in the 15 EU countries. RESULTS: The difference between Mediterranean and non-Mediterranean EU countries in a 7-point Mediterranean diet score was reduced from 2.9 in the 1960s to 1.6 in the 1990s. This reduction may underlie the reduction in the difference in general mortality between these countries, from about 100 deaths per 100,000 person-years in the early 1970s to about 50 deaths per 100,000 person-years in the 1990s. CONCLUSIONS: The decline in overall mortality in the 15 EU countries over the last 25 years is probably unrelated to diet. However, the gradual loss of the survival advantage of Mediterranean EU citizens, compared with other EU citizens, may be linked to the gradual abandonment by the former of their dietary traditions.  相似文献

OBJECTIVES: To identify and characterise dietary patterns in a middle-aged Irish population sample and study associations between these patterns, sociodemographic and anthropometric variables and major risk factors for cardiovascular disease. DESIGN: A cross-sectional study. SUBJECTS AND METHODS: A group of 1473 men and women were sampled from 17 general practice lists in the South of Ireland. A total of 1018 attended for screening, with a response rate of 69%. Participants completed a detailed health and lifestyle questionnaire and provided a fasting blood sample for glucose, lipids and homocysteine. Dietary intake was assessed using a standard food-frequency questionnaire adapted for use in the Irish population. The food-frequency questionnaire was a modification of that used in the UK arm of the European Prospective Investigation into Cancer study, which was based on that used in the US Nurses' Health Study. Dietary patterns were assessed primarily by K-means cluster analysis, following initial principal components analysis to identify the seeds. RESULTS: Three dietary patterns were identified. These clusters corresponded to a traditional Irish diet, a prudent diet and a diet characterised by high consumption of alcoholic drinks and convenience foods. Cluster 1 (Traditional Diet) had the highest intakes of saturated fat (SFA), monounsaturated fat (MUFA) and percentage of total energy from fat, and the lowest polyunsaturated fat (PUFA) intake and ratio of polyunsaturated to saturated fat (P:S). Cluster 2 (Prudent Diet) was characterised by significantly higher intakes of fibre, PUFA, P:S ratio and antioxidant vitamins (vitamins C and E), and lower intakes of total fat, MUFA, SFA and cholesterol. Cluster 3 (Alcohol & Convenience Foods) had the highest intakes of alcohol, protein, cholesterol, vitamin B(12), vitamin B(6), folate, iron, phosphorus, selenium and zinc, and the lowest intakes of PUFA, vitamin A and antioxidant vitamins (vitamins C and E). There were significant differences between clusters in gender distribution, smoking status, physical activity, body mass index, waist circumference and serum homocysteine concentrations. CONCLUSION: In this general population sample, cluster analysis methods yielded two major dietary patterns: prudent and traditional. The prudent dietary pattern is associated with other health-seeking behaviours. Study of dietary patterns will help elucidate links between diet and disease and contribute to the development of healthy eating guidelines for health promotion.  相似文献

OBJECTIVE: Little is known about the relationship of monetary diet costs to dietary intake and obesity, particularly in non-Western populations. This study examined monetary cost of dietary energy in relation to diet quality and body mass index (BMI) among young Japanese women. DESIGN: Dietary intake was assessed by a validated, self-administered, diet history questionnaire. Diet costs were estimated using retail food prices. Monetary cost of dietary energy (Japanese yen 1000 kcal-1) was then calculated. BMI was computed from self-reported body weight and height. SUBJECTS: A total of 3931 female Japanese dietetic students aged 18-20 years. RESULTS: Monetary cost of dietary energy was positively associated with intakes of fruits, vegetables, fish and shellfish, and pulses; however, higher monetary cost of dietary energy was also associated with higher consumption of fat and oil, meat and energy-containing beverages, and lower consumption of cereals (rice, bread and noodles) (all P for trend <0.01). At the nutrient level, monetary cost of dietary energy was positively associated with intakes of dietary fibre and key vitamins and minerals, but also associated positively with intakes of fat, saturated fatty acids, cholesterol and sodium, and negatively with carbohydrate intake (all P for trend <0.0001). After adjustment for possible confounders, monetary cost of dietary energy was quite weakly but significantly negatively associated with BMI (P for trend = 0.0197). CONCLUSIONS: Increasing monetary cost of dietary energy was associated with both favourable and unfavourable dietary intake patterns and a quite small decrease in BMI in young Japanese women.  相似文献

OBJECTIVE: To describe geographical differences and time trends in the supply of the most important food components of the traditional Mediterranean diet. DESIGN: Food supply data collected from national food balance sheets for the period 1961-2001. SETTING: Selected Mediterranean countries: Spain, Italy, France, Greece, Algeria, Morocco, Tunisia and Turkey. RESULTS: Differences of almost 30-fold and five-fold were found in the supply of olive oil and fruits and vegetables, respectively, among the Mediterranean countries studied during the 1960s. A favourable increasing trend for the supply of fruit and vegetables was observed in most Mediterranean countries. However, an increase in the supply of meats and dairy products and a decrease in the supply of cereals and wine were observed in European Mediterranean countries from 1961 until 2001. Only in African and Asiatic Mediterranean countries were cereals the base of food supply. During the 1990s, Greece's food supply pattern was closest to the traditional Mediterranean diet, while Italy and Spain maintained a high availability of fruits, vegetables and olive oil, but were losing the other typical components. Among African and Asiatic Mediterranean countries, only Turkey presented a traditional Mediterranean dietary pattern except with respect to olive oil, the supply of which was very low. France showed a Western dietary pattern, with a high supply of animal products and a low supply of olive oil. CONCLUSIONS: Dietary supplies in the Mediterranean area were quite heterogeneous in the 1960s and have experienced a process of Westernization, especially in European Mediterranean countries.  相似文献

OBJECTIVE: To validate an estimated food record (EFR), using a weighed food record (WFR) as the reference method, for the determination of food consumption and nutrient intakes in a group of Costa Rican adults. DESIGN: For the WFR, all foods consumed by subjects during seven consecutive days were weighed and recorded by nutrition students. Two EFRs (a 4-day and a 3-day record) were recorded by subjects with the use of home measures and photographs to estimate amounts. SETTING: Costa Rica. SUBJECTS: Sixty adults: 30 men and 30 women; 30 living in urban and 30 in rural areas. RESULTS: The EFR gave statistically significant lower average intake estimates for energy and 12 of the 22 nutrients examined. The correlation coefficients ranged from 0.68 (polyunsaturated fats) to 0.87 (calcium). The percentage of subjects classified into the same quartile ranged from 45.0% (polyunsaturated fats) to 68.3% (vitamin B12). For all nutrients except vitamin C, 0 or 1.7% were misclassified into extreme quartiles. For food group consumption, the EFR gave statistically significant lower estimates for six of the 17 groups and correlation coefficients ranged from 0.22 (fish) to 0.93 (beverages). Greater differences in estimates of mean energy and nutrient intakes were detected among subjects from rural areas, caused in part by a tendency to underestimate the amounts of rice and beans consumed. CONCLUSION: Validation of the EFR using a WFR as the reference method gave results that compare favourably with those reported by other authors, and support the use of the EFR for dietary surveys among Costa Rican adults.  相似文献

OBJECTIVE: To examine the influence of individual- and area-level socio-economic characteristics on food choice behaviour and dietary intake. SETTING: The city of Eindhoven in the south-east Netherlands. DESIGN: A total of 1339 men and women aged 25-79 years were sampled from 85 areas (mean number of participants per area = 18.4, range 2-49). Information on socio-economic position (SEP) and diet was collected by structured face-to-face interviews (response rate 80.9%). Individual-level SEP was measured by education and household income, and area-level deprivation was measured using a composite index that included residents' education, occupation and employment status. Diet was measured on the basis of (1) a grocery food index that captured compliance with dietary guidelines, (2) breakfast consumption and (3) intakes of fruit, total fat and saturated fat. Multilevel analyses were performed to examine the independent effects of individual- and area-level socio-economic characteristics on the dietary outcome variables. RESULTS: After adjusting for individual-level SEP, few trends or significant effects of area deprivation were found for the dietary outcomes. Significant associations were found between individual-level SEP and food choice, breakfast consumption and fruit intake, with participants from disadvantaged backgrounds being less likely to report food behaviours or nutrient intakes consistent with dietary recommendations. CONCLUSIONS: The findings suggest that an individual's socio-economic characteristics play a more important role in shaping diet than the socio-economic characteristics of the area in which they live. In this Dutch study, no independent influence of area-level socio-economic characteristics on diet was detected, which contrasts with findings from the USA, the UK and Finland.  相似文献

OBJECTIVE: The aims of this study were to assess the changes that have occurred in food patterns in Europe over the last 40 years based on food availability data and to compare the stability of the traditional Mediterranean diet in the south of Europe in this period. DESIGN: An ecological study carried out on the basis of Food and Agriculture Organization food balance sheets for three geographical areas of Europe (Mediterranean, north and east) over two time periods: 1961-1963 and 1998-2000. The average availability of total energy, energy provided from macronutrients and food groups was calculated for each area and each period studied. RESULTS: Over the last 40 years total energy availability and energy availability from lipids have increased considerably in the three European areas, while the percentage of energy from carbohydrates has fallen. The greatest changes have occurred in Mediterranean Europe, with an increase of 20.1% in total energy availability, an increase of 48.1% in energy availability from lipids and a fall of 20.5% from carbohydrates. Moreover, Mediterranean Europe showed a significant fall in the energy supplied by cereals (29.9%) and wine (55.2%), while the contribution of milk (77.8%) and dairy products (23.6%) increased. CONCLUSIONS: The results of this study suggest that European Mediterranean countries should take nutrition policy action to maintain their traditional healthy food pattern, with a cultural added value. This implies actions at all levels, including raising awareness of consumers, collaboration with the food sector and a call to set the agenda of the concerned politicians and stakeholders.  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: To measure change in fruit and vegetable (F&V) consumption among elementary-school children after the introduction of a salad bar programme as a lunch menu option in the US Department of Agriculture's (USDA) reimbursable lunch programme in Los Angeles Unified School District (LAUSD). DESIGN: A cross-sectional sample of children was interviewed before and after a salad bar intervention (1998 and 2000, respectively) utilising a 24-hour food recall questionnaire. Frequencies of F&V consumption were calculated. SETTING: The evaluation took place in three LAUSD elementary schools participating in the salad bar programme and the USDA reimbursable lunch programme. SUBJECTS: Three hundred and thirty-seven children in 2nd-5th grade (7-11 years old). RESULTS: After the salad bar was introduced, there was a significant increase in frequency (2.97 to 4.09, P < 0.001) of F&V consumed among the children studied. The increase in frequency of F&V consumed was almost all due to an increase during lunch (84%). Mean energy, cholesterol, saturated fat and total fat intakes were significantly lower in the children after the salad bar was introduced in the schools compared with the intakes in the children before the salad bar was introduced.Conclusion: A salad bar as a lunch menu option in the USDA reimbursable lunch programme can significantly increase the frequency of F&V consumption by elementary-school children living in low-income households.  相似文献

The high level of meat and saturated fat consumption in the USA and other high-income countries exceeds nutritional needs and contributes to high rates of chronic diseases such as cardiovascular disease, diabetes mellitus and some cancers. Affluent citizens in middle- and low-income countries are adopting similar high-meat diets and experiencing increased rates of these same chronic diseases. The industrial agricultural system, now the predominant form of agriculture in the USA and increasingly world-wide, has consequences for public health owing to its extensive use of fertilisers and pesticides, unsustainable use of resources and environmental pollution. In industrial animal production there are public health concerns surrounding feed formulations that include animal tissues, arsenic and antibiotics as well as occupational health risks and risks for nearby communities. It is of paramount importance for public health professionals to become aware of and involved in how our food is produced.  相似文献

OBJECTIVES: To undertake secondary analyses of the 1997 National Diet and Nutrition Survey of Young People aged 4-18 years in order to describe the contribution of school meals to daily food and nutrient intakes; and to compare the findings from 1997 with data collected in English primary and secondary schools in 2004-2005. DESIGN: Cross-sectional analysis of 7-day weighed inventory food consumption data according to age, sex, household income, free school meals and breakfast consumption. Comparison of food consumption with the Balance of Good Health and of nutrient intake data with the Caroline Walker Trust (CWT) guidelines. SETTING: United Kingdom. SUBJECTS: One thousand four hundred and fifty-six UK schoolchildren aged 4-18 years, 7058 English primary-school pupils and 5695 English secondary-school pupils. RESULTS: Pupils' school meal choices in 1997 did not accord with the Balance of Good Health. Food choices in school were less healthy than choices outside school. School meals failed to make good the shortfalls in daily intakes of non-starch polysaccharides and zinc in primary-school pupils, and of calcium, iron, zinc, vitamin A and non-starch polysaccharides in secondary-school pupils, nor excess daily intakes of saturated fatty acids, non-milk extrinsic sugars and sodium at all ages. School meals typically failed to meet CWT guidelines. They were more likely to meet CWT guidelines when choice of foods was restricted. CONCLUSIONS: School meals need substantial improvement to meet CWT guidelines for healthy eating. The introduction of food-based guidelines for school meals in England in 2001 did not improve the food choices in school meals.  相似文献

Inorganic arsenic (iAs) is considered to be a human carcinogen. In this paper, total (As) and iAs contents of 215 food products and drinks (i.e., seafood, fruits and vegetables, meat products, oils and fats, rice and rice products, seasonings, and alcoholic drinks) marketed in Catalonia (Spain) were quantified by inductively coupled plasma-mass spectrometry. The analytical method described was used for different food products, obtaining feasible results without the need to couple LC-ICP-MS for iAs. Daily As and iAs intakes for the average adult Catalan consumer were estimated at 354 and 6.1 μg/day/person, respectively, using consumption data from the Catalan Nutrition Survey (ENCAT). The highest As content was found in seafood, contributing 96% of dietary As intake, whereas rice presented the highest iAs values, corresponding to 67% of dietary iAs intake. As cooking process may affect iAs content, boiled rice was evaluated, showing an iAs reduction (up to 86%) when using higher water volumes (30:1 water/rice ratio) than those used in previous studies. This iAs exposure was slightly below the exposure risk range stated by the European Food Safety Authority (0.3-8 μg/kg of body weight/day), although the possibility of a risk to the population with high rice consumption cannot be excluded.  相似文献

OBJECTIVE: To conduct a comprehensive assessment of dietary intakes of nitrites and N-nitrosodimethylamine (NDMA). SUBJECTS AND SETTING: A study was conducted within the Spanish cohort of the European Prospective Investigation in Cancer and Nutrition (EPIC) to assess the intake and food sources of these compounds in Spanish adults. The study included 41,446 health volunteers, aged 29-69 years, from Northern and Southern regions. Usual food intake was estimated by in-person interviews using a computerised dietary questionnaire. RESULTS: The estimated geometric mean was 0.994 mg day(-1) for nitrites and 0.114 microg day(-1) for NDMA. For both compounds a positive trend in consumption with increasing energy intake was observed. Dietary NDMA was related to age and sex after energy adjustment, while nitrite consumption increased with higher intakes of vitamin C (P < 0.001). The food groups that contributed most to intakes were meat products, cereals, vegetables and fruits for nitrites, and processed meat, beer, cheese and broiled fish for NDMA. Current and past smokers, who had high levels of NDMA from tobacco exposure, were also identified as the highest consumers of dietary NDMA. Furthermore, smokers had low intakes of vitamin C (an inhibitor of endogenous nitrosation). CONCLUSIONS: Intake levels of NDMA and nitrites in a Mediterranean cohort are currently relatively lower than those previously reported, although processed meat, beer and cured cheese still are the most important contributors to NDMA intake.  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 examine and analyse consumption changes over time of 24 food items between Sardinia and Malta. SETTING: The data were collected in 2001 in Sardinia and 2002 in Malta. DESIGN: A structured qualitative questionnaire, articulated around four main themes: food supply, transformation, preparation and consumption habits, was administered by face-to-face interviews with the help of a local person. It encompassed mainly open-ended questions, which allowed us to measure factors contributing to change. SUBJECTS: Thirty mother-daughter pairs were interviewed in each insular territory. RESULTS: Despite a common trend revealing a shift away from cereals, pulses and potatoes to the benefit of meat products, fats and sugar, our results showed contrasting evolutions in food consumption between both insular societies. Fruit and vegetables, olive oil and fish, which are part of the main features of the Mediterranean diet, were among the top foods for which consumption frequency has increased in Sardinia. In Malta, besides an increase in olive oil and vegetable consumption, cheeses and desserts showed the highest increase. Along with modernity and improved living conditions, enhanced commercial availability and increased diversity of food preparation were also identified as factors contributing to food consumption changes. CONCLUSIONS: Although the Sardo-Mediterranean model is evolving under the impact of modernisation, it is not disappearing. In Malta, however, modernity has led to a more sudden shift from a state of food shortage to one of affluence, but in a cultural context where the identity is no longer Mediterranean but Anglo-Saxon.  相似文献

OBJECTIVE: To determine the correlates of a high-fat diet in urban, suburban and rural areas of Quebec, Canada. DESIGN: A secondary analysis of data collected as part of a 5-year multi-factorial, multi-setting, community-intervention project. SETTING: Urban, suburban and rural settings of the province of Quebec, 1997. SUBJECTS: Data were analysed from a sample of 5214 participants (2227 males, 2987 females). A food-frequency questionnaire was completed and a global index of food quality was calculated. Logistic regression was used to identify correlates of a diet high in total fats, saturated fat and cholesterol. RESULTS: In both genders, lower level of education, smoking status, French and English languages compared with other languages spoken at home, and a rural environment were associated with poor diet quality. Having no intention to eat low-fat dairy products more often was associated with a high-fat diet. In men, obesity (body mass index >/=30 kg m(-2)) and absence of reported health problems were correlates of a high-fat diet, while, in women, lower physical activity was a correlate. CONCLUSIONS: Future health interventions in Quebec should target people with low education, smokers and those living in a rural environment. Obese men and sedentary women should have access to specific dietetic resources.  相似文献

BACKGROUND: This paper describes the development of the UK Women's Cohort Study and presents cohort baseline characteristics. METHODS: In total, 35,372 women, aged 35-69 years at recruitment, were selected to ensure a wide range of dietary intakes. Diet was assessed by a 217-item food-frequency questionnaire (FFQ). Detailed lifestyle information was collected by postal questionnaire. Vegetarians, fish-eaters and meat-eaters were compared. RESULTS: The cohort women are mainly white, well-educated, middle-class and married with children. They are health-conscious with only 11% current smokers and 58% taking dietary supplements. Twenty-eight per cent of subjects self-report as being vegetarian and 1% as vegan. However, only 18% are defined as 'vegetarian' from the FFQ. Fat provides 32% of energy; vitamin and mineral intakes are high, with a broad range of intakes. Meat-eaters are older, with a higher body mass index (BMI) and the lowest intakes of carbohydrate, fibre, vitamin C, folate, iron and calcium. Other fish-eaters are similar to vegetarians. Vegetarians have the lowest intakes of protein, fat and saturated fat. Oily fish-eaters have the lowest BMI; are the least likely to smoke or use full-fat milk; and are the most likely to use dietary supplements and consume the most fruit and vegetables. Oily fish-eaters have the highest total energy intake and vegetarians the lowest. Semi-skimmed milk, bread, potatoes, wine, bananas and muesli are important contributors to energy for all groups. CONCLUSION: A large cohort of middle-aged women has been created encompassing a wide range of different eating patterns, including diets currently of interest to research into protection against cancer and coronary heart disease. Participants will be followed up to study the effects of different food and nutrient intakes on long-term health outcomes.  相似文献

OBJECTIVE: The purpose of this study was to compare dietary practices among different birth cohorts of 70-year-old Swedes, who were examined between 1971 and 2000. SETTING: G?teborg, Sweden. DESIGN: Four population-based samples of 1360 70-year-olds, born in 1901, 1911, 1922 and 1930, have undergone health examinations and dietary assessments over a period of almost three decades. One-hour diet history (DH) interviews were conducted in 1971, 1981, 1992 and 2000 with a total of 758 women and 602 women. The formats and contents of the dietary examinations were similar over the years. Statistical analysis of linear trends was conducted, using year of examination as the independent variable, to detect secular trends in food and nutrient intakes across cohorts. RESULTS: At the 2000 examination, the majority of 70-year-olds consumed nutritionally adequate diets. Later-born cohorts consumed more yoghurt, breakfast cereals, fruit, vegetables, chicken, rice and pasta than earlier-born cohorts. Consumption of low-fat spread and milk also increased, along with that of wine, light beer and candy. In contrast, potatoes, cakes and sugar were consumed less in 2000 than in 1971. The ratio of reported energy intake to estimated basal metabolic rate did not show any systematic trend over time in women, but showed a significant upward trend in men. CONCLUSIONS: The diet history method has captured changes in food selections in the elderly without changing in general format over three decades. Dietary quality has improved in a number of ways, and these findings in the elderly are consistent with national food consumption trends in the general population.  相似文献
