Dietary patterns and their socio-demographic determinants in 10 European countries: data from the DAFNE databank.

OBJECTIVE: To describe the dietary patterns of 10 European countries and their socio-demographic determinants, using the comparable between-countries DAFNE data. DESIGN: Analysis of standardized and postharmonized data collected through the national household budget surveys. SETTING: Nationally representative surveys undertaken in 10 European countries, generally in the second half of the 1990s. RESULTS: The differences in the fruit and vegetable consumption previously identified between Mediterranean and Northern European countries seem to be leveling out, particularly in relation to fruit consumption. Pulses, however, still characterize the diet of the Mediterraneans. Straying from their traditional food choices, Mediterraneans recorded high availability of unprocessed red meat, while Central and Northern Europeans preferably consumed meat products. The household availability of beverages (alcoholic and non-alcoholic) is generally higher among Central and Northern European populations. Principal component (PC) analysis led to the identification of two dietary patterns in each of the 10 countries. The first was similar in all countries and indicated 'wide-range' food buyers. The second was slightly more varied and described 'beverage and convenience' food buyers. PC1 was common among households of retired and elderly members, while PC2 was common among households located in urban or semi-urban areas and among adult Scandinavians living alone. CONCLUSIONS: The dietary patterns identified point towards a progressive narrowing of dietary differences between North and South European countries. The comparable between-countries DAFNE data could prove useful in ecological studies, in the formulation of dietary guidelines and public health initiatives addressing specific population groups.

[Nutritional planning of menus of public schools of the community of Madrid]. / Planificación nutricional de los menús escolares para los centros públicos de la Comunidad de Madrid.

Some nutritional unbalances have been observed in menus served at dining rooms of schools from the Community of Madrid (CM): small portions, inter-day variations up to 50% of energy intake, unbalances in caloric and lipidic profiles, little variety, lack of parental information, etc. The Education Council of the CM considered necessary to plan and regulate the basic conditions that menus of these dinning rooms should meet. The Spanish Nutrition Foundation (FEN) and the Nutrition Department of the Complutense University of Madrid (UCM) were put in charge of elaborating the bases to develop the Regulation (BOCM 24-05-01, 10-09-02). Collective catering companies were called for a tender to provide menus adapted to such Regulation. This work describes the adaptation of programmed dietary schemes of officially approved companies and mainly the impact on energy and nutritional content of menus and their adaptation to the recommended caloric and lipidic profiles. So far, a random sample of 171 schools with dining rooms (more than 37,000 schoolboys) has been visited by nutritionists, with no previous announcement, to control served menus. For this, at each centre a duplicate of the portion served that day was gathered. The energy and nutrient content was determined and the fatty acid composition was analysed. The adaptation to the Regulation by catering companies has substantially improved the menus as compared to previous times: more presence of vegetables, better quality of fat and less amount of fat and proteins at the expense of carbohydrates.

Teenage girls and elderly women living in northern Europe have low winter vitamin D status.

OBJECTIVE: To determine the vitamin D status (serum 25-hydroxyvitamin D; S-25OHD) in adolescent girls and elderly community-dwelling women living in four countries of northern Europe and to explain differences in S-25OHD concentrations between and within the countries. DESIGN: A cross-sectional observational study conducted in a standardised way during February-March. S-25OHD was analysed by high-performance liquid chromatography. Vitamin D and calcium intake was calculated using a standardised food composition database. SETTING: Denmark, Finland, Ireland, and Poland. SUBJECTS: A total of 199 girls (mean (s.d.) age 12.6 (0.5) y) and 221 women (mean (s.d.) age 71.8 (1.4) y). RESULTS: The median (inter quartiles) concentration of S-25OHD was 29.4 (20.3, 38.3) nmol/l for the girls and 40.7 (28.0, 54.2) nmol/l for the women. S-25OHD below 25 nmol/l was found in 37% of the girls and 17% of the women, and S-25OHD below 50 nmol/l was found in 92% of the girls and 37% of the women. Positive significant determinants for S-25OHD in girls were use of vitamin D supplements, and in women sun habits, dietary vitamin D intake, use of vitamin D and calcium supplements. Body mass index and smoking were negative determinants in women. For women predictors could explain the differences between countries (P(country) = 0.09, R(2) = 0.39), but for girls the difference remained significant even after including predictors (P(country) = 0.03, R(2) = 0.15). CONCLUSION: Vitamin D status is low in northern Europe during winter. More than one-third of the adolescent girls have vitamin D status below 25 nmol/l and almost all are below 50 nmol/l. Two-thirds of the elderly community-dwelling women have vitamin D status below 50 nmol/l. Use of vitamin D supplements is a significant positive determinant for S-25OHD for both girls and women (P = 0.001).

Body perceptions and slimming attitudes reported by Spanish adolescents.

OBJECTIVE: To assess the relationship between body mass index (BMI) and the desire to lose weight, body parts wanted to be reduced and weight-loss practices. DESIGN: A standardized questionnaire was self-completed by the participants. Anthropometric measurements were obtained by a research assistant. SUBJECTS: Forty males and 105 females from 12 to 18 y old randomly selected from education centers in Madrid, Spain. RESULTS: Body dissatisfaction in 56% of the females and the 27% of the males was observed. In spite of the low prevalence of overweight (10% males and 6% females), many adolescents reported themselves to be overweight: more girls (27%) than boys (12.5%) (P < 0.05) by Q2 (6.26) were cognitively inclined to weight loss even though they were not overweight (body mass index, BMI > 25 kg/m2). Adolescents desired a slimming of the abdomen (82% males and 52% females), thighs (18% boys and 39% girls), hips (6% and 18% males and females, respectively) and buttocks (23% males and 42% females). Methods selected to lose weight were: physical activity or sport (73% boys and 68% girls), not to have snacks (66% girls and 23% boys), select foods with low energy content (42% boys and 37% girls), follow own diet (31% girls and 23% boys), follow medical advice (31% boys and 17% girls) and trying to be amused to forget foods (13% girls and 11% boys).

Longitudinal changes in the intake of vitamins and minerals of elderly Europeans. SENECA Investigators.

OBJECTIVE: To assess longitudinal changes in intake of vitamins and minerals in elderly Europeans. DESIGN: Longitudinal study including the collection of dietary intake data in 1988/1989 and in 1993. SETTING: Baseline and follow-up data were collected from nine European towns: Belgium: Hamme (H/B); Denmark: Roskilde (R/DK); France: Haguenau (H/F) and Romans (R/F); Italy: Padua (P/I); the Netherlands: Culemborg (C/NL); Portugal: Vila Franca de Xira (V/P); Spain: Betanzos (B/E) and Switzerland: Yverdon (Y/CH). In four other towns dietary intake data were collected in 1993 only: Portugal: Coimbra (C/P); Poland: Marki (M/PL); Northern Ireland: Ballymoney-Limavady-Portstewart (BLP/NI/UK) and United States: Mansfield (Connecticut) (M/CT/USA). SUBJECTS AND METHODS: Using standardized methods, data were collected from a random sample of 658 elderly men and 731 women born between 1913 and 1918. Dietary intake data were collected by a validated modified dietary history method. RESULTS: A significant decrease in the median intake of vitamin B1, vitamin B2, vitamin B6, vitamin C or iron was observed in several towns and for most of these nutrients in H/B, R/DK, R/F and V/P. Over the 4-y follow-up period, the proportion of elderly people with nutrient intakes below the lowest European RDI's increased for various nutrients in most towns, whereas the nutrient density of the diet, especially for iron and vitamin C, decreased significantly only in a few towns. The proportion of elderly people taking nutrient supplements varied from less than 5% in H/B to 60% in R/DK. CONCLUSION: The observed decrease in intake of some vitamins and minerals in most of the participating towns, indicates an increased risk for malnutrition in elderly Europeans.

Selection of relevant dietary indicators for health.

OBJECTIVE: To define a set of dietary components that are relevant determinants for health in Europe. The selected components are intended to serve as nutrition indicators for health in the European Health Monitoring Programme and, as such, must be limited in number, relevant to health in Europe and practical for all involved countries with respect to data gathering and comparability of data. DESIGN: Major nutrition factors were determined by reviewing relevant epidemiological and clinical literature in nutrition and health as well as referring to reports from international expert groups, including the report from the project Nutrition and Diet for Healthy Lifestyles in Europe. The selection of factors was also based on the relative ease and cost involved for participating countries to obtain comparable and valid data. RESULTS: The selected factors include foods or food groups as well as individual nutrients. Biomarkers are suggested for selected nutrients that pose the greatest difficulty in obtaining valid and comparable data from dietary studies. CONCLUSIONS: The following list of diet indicators for health monitoring in Europe was agreed upon by the EFCOSUM group in 2001, in order of priority: vegetables, fruit, bread, fish, saturated fatty acids as percentage of energy (%E), total fat as %E, and ethanol in grams per day. Biomarkers were suggested for the following nutrients: folate, vitamin D, iron, iodine and sodium. Energy has to be assessed in order to calculate %E from total fat and saturated fatty acids.

Intake of energy and nutrients. Euronut SENECA investigators.

As part of the Euronut SENECA study, food consumption has been assessed in 1217 men and 1241 women, born between 1913 and 1918 and living in 18 towns in 12 European countries. The method used was a standardized modified dietary history, including a 3-day estimated record and a food frequency list based on local food patterns. Intakes of energy, protein, fat, carbohydrate, fatty acids, cholesterol and alcohol are described in this paper. As expected, a difference between men and women in energy and nutrient intake was observed in all towns. There was a great variation between towns in mean dietary intakes of all dietary components. Mean energy intake of men ranged from 12.7 MJ in Marki (Poland) to 8.2 MJ in Yverdon (Switzerland) and Chateau Renault-Amboise (France). For women the range was from 10.9 MJ in Marki (Poland) to 6.3 MJ in Yverdon (Switzerland) and Vila Franca de Xira (Portugal). A geographical pattern can be detected for the intake of fatty acids. Intakes of saturated fat were lower in southern than in northern European towns. The calculated ratio for intakes of unsaturated and saturated fatty acids (polyunsaturated fatty acids plus monounsaturated fatty acids/saturated fatty acids) for all participants was higher in the southern European centres than in the northern centres and ranged from 2.7 in Markopoulo (Greece) to 1.2 in Elverum (Norway) and Marki (Poland). Alcohol consumption was considerable higher in men than in women. In men a north-south gradient in alcohol intake can be detected, with the highest intake in the two centres in Italy, where, on average 11% of energy intake was derived from alcohol.

Longitudinal changes in the intake of energy and macronutrients of elderly Europeans. SENECA Investigators.

OBJECTIVE: To assess longitudinal changes in intakes of energy and macronutrients in elderly Europeans. DESIGN: Longitudinal study including a dietary assessment in 1988/1989, which was repeated in 1993. SETTING: Serial data were collected in nine European towns: Belgium: Hamme (H/B); Denmark: Roskilde (R/DK); France: Haguenau (H/F) and Romans (R/F); Italy: Padua (P/I); the Netherlands: Culemborg (C/NL); Portugal: Vila Franca de Xira (V/P); Spain: Betanzos (B/E) and Switzerland: Yverdon (Y/CH). In other centres dietary intake data were collected in 1993 only: Portugal: Coimbra (C/P); Poland: Marki (M/PL); Northern Ireland: Ballymoney-Limavady-Portstewart (BLP/NI/UK) and United States: Mansfield (Connecticut) (M/CT/USA). SUBJECTS AND METHODS: Using standardized methodologies, data were collected from a random stratified sample of elderly men and women born between 1913 and 1918. In 1993 dietary intake data were collected from 1125 subjects by a modified validated dietary history method. RESULTS: Over the 4-year study period, a decline in mean energy intake of one MJ or less per day was observed in most towns, which was significant (P < 0.01) in only four of the towns. The within- and between-centre variation of change was large. Overall, a slight decline was reported for all macronutrients and with the exception of protein, large within and between centre variations were observed in both men and women. CONCLUSION: Intake of energy and macronutrients was found to decline with age. This may be of special concern for small eaters.

Household budget survey nutritional data in relation to mortality from coronary heart disease, colorectal cancer and female breast cancer in European countries. DAFNE I and II projects of the European Commission. Data Food Networking.

OBJECTIVE: We have undertaken a study to examine whether Household Budget Survey (HBS)-derived nutritional patterns are related to mortality from diseases with strong nutritional components, namely coronary heart disease, colorectal cancer and cancer of the female breast. DESIGN: Ecological correlation study. In the context of the Data Food Networking projects of the European Union, raw data from the national HBS of 10 European countries were provided. For each of the 10 participating countries, daily food availability per capita around 1990 was calculated. Individual foods were aggregated into 12 major food groups that were linked with the diseases under consideration. Mortality data were available from a World Health Organisation database. We have used a composite score to summarise the postulated influence of diet. SETTING: Ten European countries circa 1990. RESULTS: The correlation coefficients between the composite score and the age-adjusted mortality from each of the studied diseases were: + 0.51 (P approximately 0.14) for colorectal cancer; +0.72 (P approximately 0.02) for female breast cancer; and +0.60 (P approximately 0.07) for coronary heart disease, after adjustment for tobacco smoking. CONCLUSIONS: We conclude that dietary information from HBS is sufficiently reliable to reveal correlations with mortality rates from chronic diseases with fairly strong nutritional roots. HBS data could be used, with little cost, for monitoring secular trends in dietary patterns with a view to their health implications.

Association between trans fatty acid intake and cardiovascular risk factors in Europe: the TRANSFAIR study.

BACKGROUND: High intakes of trans fatty acids (TFA) have been found to exert an undesirable effect on serum lipid profiles, and thus may increase the risk for cardiovascular disease. OBJECTIVES: Investigation of the association between TFA intake and serum lipids. DESIGN: Cross-sectional study in eight European countries (Finland, France, Greece, Iceland, The Netherlands, Portugal, Spain, Sweden) among 327 men and 299 women (50-65 y). Using a dietary history method, food consumption was assessed and TFA intake was calculated with recent figures on TFA levels of foods, collected in the TRANSFAIR study. RESULTS: Mean (+/-s.d.) TFA intake was 2.40+/-1.53 g/day for men and 1.98+/-1.49 g/day for women (0.87+/-0.48% and 0. 95+/-0.55% of energy, respectively), with the highest consumption in Iceland and the lowest in the Mediterranean countries. No associations were found between total TFA intake and LDL, HDL or LDL/HDL ratio after adjustment for cardiovascular risk factors. Additional adjustment for other fatty acid clusters resulted in a significant inverse trend between total TFA intake and total cholesterol (Ptrend<0.03). The most abundantly occurring TFA isomer, C18:1 t, contributed substantially to this inverse association. The TFA isomers C14:1 t9, C16:1 t9 and C22:1 t were not associated or were positively associated with LDL or total cholesterol. CONCLUSIONS: From this study we conclude that at the current European intake levels of trans fatty acids they are not associated with an unfavourable serum lipid profile.

Intake of fatty acids in western Europe with emphasis on trans fatty acids: the TRANSFAIR Study.

OBJECTIVE: To assess the intake of trans fatty acids (TFA) and other fatty acids in 14 Western European countries. DESIGN AND SUBJECTS: A maximum of 100 foods per country were sampled and centrally analysed. Each country calculated the intake of individual trans and other fatty acids, clusters of fatty acids and total fat in adults and/or the total population using the best available national food consumption data set. RESULTS: A wide variation was observed in the intake of total fat and (clusters) of fatty acids in absolute amounts. The variation in proportion of energy derived from total fat and from clusters of fatty acids was less. Only in Finland, Italy, Norway and Portugal total fat did provide on average less than 35% of energy intake. Saturated fatty acids (SFA) provided on average between 10% and 19% of total energy intake, with the lowest contribution in most Mediterranean countries. TFA intake ranged from 0.5% (Greece, Italy) to 2.1% (Iceland) of energy intake among men and from 0.8% (Greece) to 1.9% among women (Iceland) (1.2-6.7 g/d and 1.7-4.1 g/d, respectively). The TFA intake was lowest in Mediterranean countries (0.5-0.8 en%) but was also below 1% of energy in Finland and Germany. Moderate intakes were seen in Belgium, The Netherlands, Norway and UK and highest intake in Iceland. Trans isomers of C18:1 were the most TFA in the diet. Monounsaturated fatty acids contributed 9-12% of mean daily energy intake (except for Greece, nearly 18%) and polyunsaturated fatty acids 3-7%. CONCLUSION: The current intake of TFA in most Western European countries does not appear to be a reason for major concern. In several countries a considerable proportion of energy was derived from SFA. It would therefore be prudent to reduce intake of all cholesterol-raising fatty acids, TFA included.

Activities of daily living in the Spanish elderly. Association with mortality.

The ability to manage basic activities of daily living (ADL) is a significant predictor for being housebound, placement in a nursing home and death. The aim of the study was to assess the capacity to perform activities of daily living in the Spanish sample (30 men and 49 women aged 80-85 y) from SENECA's Finale study (1999) and changes respect to the same sample ten years ago. The total ADL score (assessed by 16 questions) and the partials (mobility ADLm and self-care ADLc) show that the total ADL average in 1999 has been 23.9+/-10.2 (p<0.05) and 25.3+/-9.6 (p<0.001), being in 1989, 18.8+/-4.4 and 19.9+/-4.8 for men and women respectively. The ADL score from deceased subjects participating in 1989 was significantly worse (p<0.01 in men and p<0.001 in women) than ADL score from survivor subjects. Activities of daily living as a measurement of functionality decline with increasing age and in our study a better ADL score was found as survival factor.

Ten-year changes in anthropometric characteristics of elderly Europeans.

OBJECTIVE: Assess longitudinal (10-y) changes in height, body weight and circumferences in elderly Europeans. DESIGN: Longitudinal assessments including baseline measurements taken in 1988/1989 which were repeated in 1993 (follow-up) and in 1999 (Finale). SETTING: Longitudinal data were collected in nine European research towns: Hamme/Belgium (H/B), Roskilde/Denmark (R/DK), Haguenau/France (H/F), Romans/France (R/F), Padua/Italy (P/I), Culemborg/the Netherlands (C/NL), Vila Franca de Xira/Portugal (V/P), Betanzos/Spain (B/E), Yverdon/Switzerland (Y/CH). SUBJECTS: Using standardised methodologies data were collected from a random stratified sample of elderly men and women born between 1913 and 1918 including a total of 662 subjects in 1999. RESULTS: On average stature had decreased by 1,5-2 cm. Mean weight changed by -2.6 kg to - 4.2 kg in only three towns. An increase of at least 5 kg of body weight had taken place in 13 % of both men and women whereas 23 % of men and 27 % women had lost at least 5 kg of their baseline weight. Such weight loss over the first 4 years of follow-up was associated with higher mortality rates in men (crude RR 2.2, p<0.0001). Serial changes in arm circumference were small but waist circumference had increased by 3-4 cm. CONCLUSIONS: Whilst small-to-modest average changes in height, body weight and circumferences emerged over SENECA's 10-year follow-up period, considerable gains and losses of body weight had occurred in a significant proportion of the SENECA populations, whereby early weight loss might be predictive of subsequent survival.

Theoretical study of the intake of trace elements (nutrients and contaminants) via total diet in some geographical areas of Spain.

The aim of this study was to monitor exposure to heavy metal contaminants from habitual diets and to estimate the health risk for the consumer by comparing the analyzed content with the acceptable daily intake (ADI). This study is based on the household consumption as assessed by the National Institute of Statistics (INE) and our department. The number of food groups (237) consumed by the population (national and the 17 Autonomy Communities) is considered. A list of the metal content of foods in included. The data were collected from reports issued by the Ministry of Health, other official organizations, and from specialized literature. The results show that the intakes of arsenic (0.019 mg/person/d), mercury (0.004 mg/person/d), and lead (0.082 mg/person/d) do not reach the ADI, but that of cadmium exceeds the ADI in some geographical areas. The intake of zinc and chromium does not exceed the dietetic recommendations.

Energy intake as a determinant factor of vitamin status in healthy young women.

The vitamin (B1, B2, B6, retinol, beta-carotene, E and ascorbic acid) status of 56 young women (aged 21-30 years) has been analysed by studying dietary intakes and biochemical parameters and relating them to energy intake. Only 25% of the sample consumed more than 2000 kcal/day and a high percentage of apparently healthy women had low vitamin intakes, especially in the case of vitamin E, B6 and retinol. Except for retinol and beta-carotene, significant correlations between energy and vitamin intakes were found. With respect to blood levels, 86% of women had deficient or marginal levels for B1, 71% for B2, 75% for B6 and 64% for beta-carotene. An adequate or optimal situation has been shown in the case of vitamin C (92%), E (88%) and retinol (77.5%). No correlation between energy intake and vitamin blood levels was found, except for vitamin B6. These data show that young women are vulnerable to developing vitamin deficiencies, especially those consuming low energy diets.

Dietary assessment of a pregnant Spanish women group.

Dietary habits were studied in 135 pregnant Spanish women. Their consumption of cereals, sugars, oils, vegetables, legumes and alcoholic drinks was lower, that of meat and eggs similar and that of fruit, milk and fish higher than the Spanish national average. The percentages for intakes lower than 100% of the recommended allowances, taking into account the dietary intake were 12, 23, 88, 8, 12, 34, 94, 2, 71, 98, 97 and 93% for thiamin, riboflavin, folates, vitamin B12, C, A, D, iodine, calcium, zinc magnesium and iron, respectively. If the supplements prescribed halfway through the pregnancy are added to the dietary provisions, the percentages for consumption below 100% of recommendation were considerably reduced. Furthermore, since the supplements prescribed did not include zinc or magnesium, there were 98% and 97% of pregnant women, respectively, with intakes below 100% of recommendations of these minerals. In the other cases the dietary intake plus the supplement are higher than the recommended amount. These imbalances may have harmful effects on the health of the women and their newborns and highlight the need for studying in depth the nutritional problems of pregnant women and for reconsidering the supplements that must be prescribed.

The influence of dietary intake and sunlight exposure on the vitamin D status in an elderly Spanish group.

Traditional dietary habits and the living style in Spain should theoretically be enough to assure a healthy vitamin D status: a very high fish intake and one of the highest sun exposure rates of all countries in Europe. However, in spite of this, there is a high percentage in the elderly showing low vitamin D serum values. This paper is part of the Euronut-SENECA study, a major multicentre survey assessing the nutritional status in the elderly from 19 centres over 12 countries in Europe. In it, the vitamin D status in 55 healthy individuals from Spain has been studied and assessed by measuring dietary and supplemental vitamin D intakes; the influence of sunlight exposure such as physical activity, permanence in the sun, clothing, etc.; and 25-hydroxyvitamin D [25 (OH)D] serum concentration. The mean dietary intake was 1.3 +/- 1.5 micrograms/day, being fish, and specially fatty fish, the main source (62%). Of the total, 85% of the elderly did not reach the Spanish recommended dietary intake (2.5 micrograms/day). The mean 25(OH)D serum level was 25 +/- 14.7 nmol/l and there was a high percentage with deficit (13%) (8.4 +/- 1.9 nmol/l) and marginal (62%) (19.8 +/- 4.2 nmol/l) levels. People who usually walked 1.9 +/- 1.3 hours/day or stayed in the sun "every day" or "as much as possible", had higher (p < 0.05) serum 25 (OH)D concentrations (27.7 +/- 2.4 nmol/l and 31.3 +/- 3.7 nmol/l, respectively) than people who did not (16.6 +/- 1.2 nmol/l and 21.3 +/- 2.1 nmol/l, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

[Body mass index and the desire of weight loss in a group of young women]. / Indice de masa corporal y deseo de perder peso en un grupo de mujeres jóvenes.

With the aim of obtaining information as to whether the desire to lose weight responds to criteria of health, or whether this is only a question of esthetics, the relation between the body mass index (BMI) as an indicator of obesity, and some attitudes with respect to weight, were analyzed in a group of 254 apparently healthy women between the ages of 14 and 55 with a variety of occupations (students, housewives, and women working outside the home), using a questionnaire designed for the study. An analysis was also made of the types of methods used for the voluntary loss of weight, as well as other aspects of slimming. The sample was classified into three groups according to the BMI: low weight (BMI < 20 kg/m2), adequate weight (BMI = 20-25 kg/m2), and overweight (BMI > 25 kg/m2). Of the total number of women studied, only 42% were satisfied with their weight. Of those with a low weight, 35% manifested discontent, and of these, 69% wanted to lose weight and only 19% had attempted to increase it. Among the women with and adequate BMI, 71% indicated not being content with their weight, with 95% wishing to reduce it. In the group of overweight women only 13% were satisfied and all the rest expressed a desire for losing weight. The size and volume of the thighs (28%), hips (22%), buttocks (20%), and abdomen (19%) were the areas producing the greatest amount of discontent. The most common methods for losing weight were: no snacking between meals (54%), physical exercise (53%), and low calorie diets (33%). Only 19% went to see a specialist. The use of laxatives (1.5%) and other slimming products (3.5%) was minimal.

[Influence of the aging process on body composition of the aged: the SENECA study in Spain]. / Influencia del proceso de envejecimiento en la composición corporal de personas de edad: estudio SENECA en España.

The maintenance of an adequate proportion of muscular mass in aging, is critical for the quality of life of elderly people. In the face of the lack of longitudinal data, the semi-longitudinal SENECA (Survey in Europe on Nutrition and the Elderly, a Concerted Action) study was proposed, with the aim, among others, of analyzing the influence of the aging process on the body composition. In this study, the results are presented which correspond to the changes in body composition seen between the baseline study and the follow up period (1989-1993), in the participating Spanish population, which was randomly selected, and whose ages were between 70 and 80 years. There is also an analysis of the relation existing in 1993, between different anthropometric measurements and the functionality evaluated objectively by means of the physical and functional capacity test (PPT). Using a standardized methodology, the following were measured: size, breadth, weight, biceps and triceps fold, and the circumference of the waist, hips, and the upper arm. Based on these measurements, we calculated the body mass index (BMI), the waist/hip ratio, the muscular circumference of the arm, the fat mass, and the fat free mass. The longitudinal analysis between 1989-1993 showed a decrease for both sexes, in weight (-3.5 +/- 5.0 in men, and -3.4 +/- 4.0 kg in women: p < 0.001) and body circumferences; and also, in women, in the size and the triceps fold (-0.63 +/- 1.42 cm, p < 0.01, and -3.6 +/- 4.6 mm, p < 0.001, respectively). Consequently, the BMI (-1.4 +/- 1.8 for men and -1.4 +/- 1.8 kg/m2 in women, p < 0.01) decreased, while the waist/hip ratio did not change. A reduction of the fat free mass of -1.6 +/- 2.1 kg (p < 0.01) in men and -1.2 +/- 1.3 kg in women (p < 0.001), was observed, as well as a reduction of the body fat of -1.8 +/- 2.0% and -1.7 +/- 2.6% (p < 0.001), respectively. On the other hand, analyzing the anthropometric measurements of the follow up study, a positive association was detected for men, between the waist and hip measurements and the functionality measured by the PPT.

[Age-related changes in the dietary intake of elderly individuals. The Euronut-SENECA study]. / Cambios con la edad en la ingesta dietética de personas de edad avanzada. Estudio Euronut-SENECA.

There are few longitudinal studies linking eating habits, diets, nutritional content and their repercussions on health. For this reason, the European Union's Concerted Action on Nutrition and Health, Euronut, organized an international, multi-centric longitudinal cohort study in 1988 in an attempt to analyze these factors in various food cultures of Europe. This study was given the name SENECA (Survey in Europe on Nutrition and the Elderly: a Concerted Action). To this end, several types of tests were performed: a general questionnaire (collecting information on: personal details, social and demographic status, socio-economic situation, lifestyle and physical activity and dietary or other living habits), a dietary study, anthropometric and biochemical parameters. The present paper has attempted to assess the differences due to gender and age (in the same subjects), for which purpose data has been collated from a group of individuals between 71 and 80 years of age on the quantitative and qualitative food consumption, energy and nutrient intake and their contribution to the recommended daily intake. The four groups of foods most consumed in both parts of the study were: fruit, milk and its derivatives, vegetables, and cereals and their derivatives, during the four years that have elapsed, a significant reduction was seen in the consumption of certain foods, both in the total of the sample and for the distribution by gender. As a result, with a four-year increase in age, i.e. in the second part of the study, a reduction in energy intake was observed to have a considerable impact on the intake of most micronutrients. The percentile distribution shows that there are individuals who consume very small amounts (or nothing at all) of certain foods. High percentages of individuals were seen not to cover the recommended intake.
