BACKGROUND: Mediterranean diets are felt to be healthful diets linked with reduced mortality from diet-related noncommunicable diseases. OBJECTIVE: To examine trends in diet, activity, obesity and diet-related noncommunicable diseases for Spain and compare these with other European countries, particularly those from the Mediterranean area. DESIGN: A combination of large-scale primary and secondary nationally representative data analysis are used. DATA: Nationally representative data on household food consumption, physical activity, adult obesity, and cause of death are combined with regionally representative adolescent obesity data, obtained in the last four decades. Comparative diet and obesity data come from nationally representative comparable data, obtained during the same period. RESULTS: The Spanish diet has shifted toward a very high level of fat intake, high fruit and dairy intake and moderate vegetable intake. Dairy and fruit intakes were the highest in Europe, as was the proportion of energy from fat, when we compared with the available data. Adult overweight and obesity trends show a marked increase in the past decade to levels as high as Italy and far above France. Overweight for children aged 6-7 is above that of even the USA, while adolescent overweight levels are among the highest in the world. Cardiovascular disease mortality is low, as with Italy and France, and the cancer mortality rate is lower than Italy and France. CONCLUSIONS: We have observed that, in Spain, relatively high obesity prevalences and dairy intake levels are related to much lower levels of cardiovascular disease and cancer mortality than are found in other European countries. This unique Spanish dietary and obesity pattern should be further explored in order to clarify the causal links. SUPPORT: The National Institutes of Health (NIH; R01-HD30880 and R01-HD38700). 相似文献

OBJECTIVE: To determine the trends in locations and food sources of Americans stratified by age group for both total energy and the meal and snack subcomponents. RESEARCH METHODS AND PROCEDURES: Nationally representative data was taken from the 1977 to 1978 Nationwide Food Consumption Survey and the 1989 to 1991 and 1994 to 1996 (and 1998 for children age 2 through 9) Continuing Surveys of Food Intake by Individuals. The sample consisted of 63,380 individuals, age 2 and up. For each survey year, the percentage of total energy intake from meals and snacks was calculated separately for 2- to 18-year-olds, 19- to 39-year-olds, 40- to 59-year-olds, and those 60 years and older. The percentage of energy intake by location (at-home consumption or preparation, vending, store eaten out, restaurant/fast-food, and school) and by specific food group was computed for all age groups separately. RESULTS: The trends in location and food sources were almost identical for all age groups. Key dietary behavior shifts included greater away-from-home consumption; large increases in total energy from salty snacks, soft drinks, and pizza; and large decreases in energy from low- and medium-fat milk and medium- and high-fat beef and pork. DISCUSSION: Total energy intake has increased over the past 20 years, with shifts away from meals to snacks and from at-home to away-from-home consumption. The similarity of changes across all age groups furthers the assertion that broad-based environmental changes are needed to improve the diets of Americans. 相似文献

Psychiatric considerations in the patient receiving organ transplantation: a clinical case conference 总被引:1,自引:0,他引:1
Psychiatric consultations to evaluate a patient's suitability to receive organ transplantation can require the integration of multiple types and sources of information. A patient's social support network, history of treatment compliance, ongoing Axis I and Axis II disorders, and understanding of the procedure and follow-up required must all be evaluated during such a consultation. This article presents the case of a woman with borderline personality disorder who developed hepatic failure following a drug overdose, and discusses her evaluation for liver transplantation. The discussion frames the pertinent issues in the transplant evaluation and describes the perioperative (transplant) management of the borderline patient. 相似文献

OBJECTIVE: To investigate opportunities for, and types of decision making in the general practice (primary care) consultation, and examine differences in skills of those doctors who are successful at meeting their patients' preferences and those who are less successful. DESIGN: Observation study of doctor-patient consultations in general practice. PARTICIPANTS: Patients attending for routine appointments in 12 general practice surgeries across Oxfordshire. METHODS: A total of 212 doctor-patient consultations were video-recorded. The patients involved completed a questionnaire to elicit their perceptions of how decisions were made. The video-taped recordings were coded with a new instrument, the Evidence Based Patient Choice Instrument (EBPCI), to classify the number and type of decision-making opportunities arising during each consultation. A total of 149 recordings were coded using the Oxbridge Rating Scale to assess the doctors' consultation styles. RESULTS: There was a range of decision-making opportunities in addition to those involving medical treatment. With the exception of 'fitness for work', decisions were generally 'doctor led'. There was only moderate agreement between patient perceptions of their level of involvement in decision making and the objective ratings using the EBPCI. There was wide variation in the ability of doctors to meet their patients' preferences for involvement. CONCLUSIONS: There are many decisions made in primary care consultations, in addition to those about medical treatments, in which patients could be involved to a greater extent than they currently are. Some doctors are significantly better than others at meeting different patients' preferences for their decision-making role. Patients' perceptions of shared decision making appears to be influenced by the doctors' general consultation skills. 相似文献

Summary: A case report is described in which abdominal pregnancy was misdiagnosed by ultrasound scanning as a pregnancy within a horn of a bicornuate uterus. Two serum alpha fetoprotein (SAFP) results were greatly elevated and an amniocentesis was performed, the liquor alpha fetoprotein (LAFP) and karyotype were normal. Elective Caesarean section was performed at 38 weeks for a persistent transverse lie and an abdominal pregnancy was found. The outcome was excellent for both the mother and child.
This is the first reported case of amniocentesis and measurement of LAFP in an abdominal pregnancy and confirms abdominal pregnancy as a rare cause of an elevated SAFP. 相似文献

The main purpose of this study was to compare rectal and axillary temperature measurements in African children. Altogether 573 sick children were seen in an outpatient setting in rural West Africa. Rectal and axillary temperatures were measured and the parent or guardian was asked if they thought that the child had a raised body temperature. Normal ranges were defined from an age matched population of 203 healthy children. A raised axillary temperature predicted a raised rectal temperature with a sensitivity of 98% and a specificity of 88%. The parents' impression that their child had a fever was a less sensitive (89%) and less specific (59%) indicator of raised rectal temperature. A raised axillary temperature is a good screening test for a raised rectal temperature in African children. 相似文献

Radiographs, computed tomograms, and radionuclide bone scans were obtained preoperatively in three children with fibromatosis involving the bones and soft tissues of the extremities. Two of the children had identical scar-like bone lesions of the proximal tibia, which, to the authors' knowledge, have not been reported before in this disease. The lesions recurred in two children. 相似文献

OBJECTIVES. The purpose of this study was to ascertain how economic reform has affected nutritional well-being of the elderly in the Russian Federation. METHODS. A sample of more than 2932 Russians 60 years of age and older was selected from a nationally representative survey of Russian households. A 24-hour dietary recall and data on weight, height, and socioeconomic status were collected during 1992 and 1993 and from a separate nationally representative sample of 1955 persons in the same age group in 1994. RESULTS. Russia's elderly did not experience major declines in economic or nutritional well-being during the first 2 years of the reform period. Dietary composition shifted slightly toward reduced fat consumption. A small proportion of individuals showed signs of underweight. Of those who were underweight in 1992, none had lost more than 3 kg of weight by 1993. Among those 70 years of age and older, none who were underweight had lost any appreciable weight, although half lost small amounts. CONCLUSIONS. Many more underweight elderly people increased than reduced their weight. Mean weight increased among all body mass index groups over the year reported here. However, economic conditions in December 1994 raise concerns. 相似文献

Emphysema in the renal allograft 总被引:1,自引:0,他引:1
Two diabetic patients in whom emphysematous pyelonephritis developed after renal transplantation are described. Clinical recognition of this unusual and serious infection is masked by the effects of immunosuppression. Abdominal radiographic, ultrasound, and computed tomography findings are discussed. The clinical presentation includes urinary tract infection, sepsis, and acute tubular malfunction of the allograft in insulin-dependent diabetics. 相似文献

Cluster analysis methods help to clarify the activity-BMI relationship of Chinese youth 总被引:2,自引:0,他引:2
OBJECTIVE: To use cluster analysis to create patterns of overall activity and inactivity in a diverse sample of Chinese youth and to evaluate their use in predicting overweight status. RESEARCH METHODS AND PROCEDURES: The study populations were drawn from the 1997 and 2000 years of the longitudinal China Health and Nutrition Survey, comprised of 2702 and 2641 schoolchildren in the 1997 and 2000 cross-sectional samples, respectively, and 1175 children in the longitudinal cohort. Cluster analysis was used to group children into nonoverlapping activity/inactivity "clusters" that were subsequently used in models of prevalent and incident overweight. Results were compared with traditional models, with activity and inactivity coded separately, to assess whether further insight was gained with the cluster analysis methodology. RESULTS: Moderately and highly active youth were shown to have significantly decreased odds of overweight in both cross-sectional and longitudinal analyses using cluster analysis. In incident longitudinal models, youth in the high activity/high inactivity cluster had the lowest odds of overweight [odds ratio=0.12 (0.03, 0.44)]; in contrast, results from traditional models failed to show any significant relationship between overweight and activity or inactivity. DISCUSSION: Cluster analysis methods allow researchers to simultaneously capture activity and inactivity in new ways. In this comparative study, only with the clustering methodology did we find a significant effect of activity on incident overweight, furthering our ability to examine this complex relationship. Interestingly, no effect of increasing levels of inactivity was observed using either method, indicating that activity seems to be the more important determinant of overweight in this population. 相似文献
