The health of elderly people is often affected by inadequate nutritional intake. Psychosocial determinants and the higher prevalence of acute and chronic illnesses are risk factors for nutritional deficiencies in the elderly. Nutritional assessment (NA) or nutritional risk screening must be an important element in care programmes for elderly people in the community and should be part of all geriatric assessment programmes.

BACKGROUND: To evaluate lifestyle and dietary intake factors influencing the accumulation of abdominal fat in a Mediterranean population. SUBJECTS AND METHOD: A cross-sectional study was carried-out in Spain (Asturias, Granada, Murcia, Navarra and Guipuzkoa) among 23,228 women and 14,332 men aged 29-69 years, participants of a large European prospective cohort (EPIC). Information on usual food intake and other non-dietary factors were collected by interviews. Height, weight, waist circumference and hip circumference were taken by previously trained interviewers. RESULTS: In a multiple-linear regression analysis sports activities and educational level were negatively associated with abdominal obesity, while body mass index, age, tobacco and alcohol consumption, saturated fat intake and increased prevalence of hypertension, diabetes and myocardial infarction were positively associated. All dietary and non-dietary variables accounted for 22 and 27% of variance in the waist/hip ratio and 74 and 66% of variance in the waist circumference, in women and men respectively. CONCLUSIONS: Body mass index and age are the most important factors influencing the accumulation of abdominal fat. Dietary factors and other lifestyle factors seem to play a minor role in increasing abdominal obesity.
BACKGROUND: Although the fatty acid fractions provide similar metabolizable energy, the type of dietary fat consumed could be relevant to the development of obesity. OBJECTIVE: To investigate the relationship between body mass index (BMI), obesity and the consumption of different types of fat and olive oil in a Mediterranean country with high prevalence of obesity, and high intake of monounsaturated fatty acids (MUFA) and olive oil. SUBJECTS: The study was carried out in Spain among 23 289 women and 14 374 men, aged 29-69 years, who were participants of a large European prospective cohort. METHODS: : Information on usual food intake was collected by interviewers by means of a dietary history questionnaire. The association between obesity (BMI >/= 30 kg m2), dietary fat, other dietary patterns and other non-dietary factors were tested using multilinear regression analysis. The ratio of reported energy intake to energy requirement was used as an estimation of dietary underreporting. RESULTS: The association between fatty acid fractions intake (saturated fatty acids (SFA) in women, and MUFA and polyunsaturated fatty acids (PUFA) in both sexes) and BMI was very weak, accounting for less than 1% of variance. All dietary and non-dietary variables accounted for 21% of variance in the measurement of BMI in women and only 6.7% of variance in men. Estimated underreporting of energy intake was 17.5% in obese women and 5.5% in obese men. CONCLUSIONS: The association between consumption of specific types of dietary fat, olive oil and obesity in Spain is not very important. However, because of the cross-sectional design and some level of underreporting of energy intake observed in overweight subjects and overreporting in underweight subjects, systematic bias cannot be completely discarded.
OBJECTIVE: To evaluate the association of vegetable and fruit intake with several demographic, anthropometric, lifestyle and dietary factors. DESIGN AND SETTING: Cross-sectional analysis. Information on habitual diet was collected by means of the diet history method. Association of vegetable and fruit intakes with other factors was assessed separately by means of multiple lineal regression and the cumulative odds model. SUBJECTS: 39622 healthy subjects aged 29-69 years from the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort in Spain. RESULTS: Fruit intake increased with age, education and physical activity and decreased with intake of saturated fatty acids and cholesterol; smoking and alcohol consumption were also negatively associated with fruit, with a very low consumption for current smokers and heavy drinkers. Vegetable intake increased with education and physical activity and with intake of unsaturated fatty acids, mainly monounsaturated. Former smokers consumed more vegetables than never or current smokers and non-consumers of alcohol ate less vegetables than consumers, among whom no differences were observed. All these estimates were adjusted by energy and body mass index (BMI). CONCLUSIONS: When assessing the association of fruit and vegetables with chronic diseases it is important to take into account confounding factors. Furthermore, it would be useful to study dietary patterns including several interrelated factors.
OBJECTIVE: To assess the consumption of vegetables and fruits (V&F) in adults from five regions in Spain according to sex, age and educational level. DESIGN: Cross-sectional study within the members of the EPIC cohort in Spain. SETTING: Three regions of the north of Spain (Asturias, Guipúzcoa and Navarra) and two regions of the south of Spain (Granada and Murcia). SUBJECTS: 41448 healthy volunteers (15365 men, 25813 women), aged 29-69 y. INTERVENTIONS: Information on habitual diet during the previous year was collected by means of a computerised version of a diet history questionnaire. RESULTS: Among men, the mean daily consumption of vegetables and of fruits was 273.7 g (3.4 servings) and 348.3 g (4.4 servings) respectively. Among women, the corresponding vegetables and fruit intakes per day were 244.4g (3.1 servings) and 349.4g (4.4 servings). The total V&F intake tended to increase with age and educational level. Overall, 74% of subjects consumed 400 g/d (5 servings) of vegetables and fruit. CONCLUSIONS: Consumption of vegetables and fruits in healthy adults in Spain is considerably higher than in most European countries and the United States; this complies with what is considered to be the Mediterranean diet. Despite some regional differences, there were no clearly differentiated patterns of V&F intake between southern and northern regions within Spain.
AIM: Burnout syndrome refers to a kind of occupational stress that can have psychosomatic, behavioral, emotional, familial, and social repercussions; it can also cause absenteeism and loss of efficacy at work. The aim of this study was to determine the prevalence of burnout among staff in a district hospital, as well as the personal and working characteristics associated with the syndrome. METHODS: A cross-sectional study was designed in which a representative random sample of 300 workers, stratified according to professional group, was given the Maslach Burnout Inventory to measure the degree of burnout. This questionnaire has three subscales: emotional exhaustion (EE), depersonalization (DP) and personal achievement (PA). RESULTS: A high degree of burnout was found for EE in 13.9% of the staff interviewed, in 11.1% for DP and in 6.6% for PA. None of the interviewees had high scores for all three scales while 27% had a high level of burnout in at least one of the scales. In the multivariate analysis, professional category and sex were statistically significantly associated with a high level of burnout. CONCLUSION: The prevalence of burnout in Mataró Hospital (Spain) is relatively low and depends mainly on sex and professional group.
Between March 1991 and May 1995, physicians diagnosed four cases of acute lymphoblastic leukemia, one case of Hodgkin's disease, and one case of aplastic anemia among children who resided in a small town near Barcelona that contained 4,237 inhabitants. The four cases of acute lymphoblastic leukemia represented a significant excess of observed cases (26.4/100,000 for children age 0-14 y [p < .005]). The authors conducted an epidemiological study of the population to explore the possible "local" role of agents hypothesized or known to be potentially associated with acute lymphoblastic leukemia, as well as with other hematopoietic diseases. The small town in which the cases lived is a residential area without known or suspected industrial exposures associated with leukemia. However, it is located in a county ("Maresme") that boasts having the most flower-growing and agricultural undercover producing area in Catalonia; consequently, copious amounts of herbicides and pesticides are used. The small number of cases limited the testing of the hypothesis of a causal relationship between environmental pesticide exposure or a viral infection (the only factors common to the cases) and the excess of leukemia cases. Despite the weaknesses inherent in our study, the information gleaned from our research may be useful to researchers who define local health-related problems.
