Objective To examine the relationship of cancer prevention-related nutrition knowledge, beliefs, and attitudes to cancer prevention dietary behavior.Subjects/setting Noninstitutionalized US adults aged 18 years and older.Methods Data collected in the 1992 National Health Interview Survey Cancer Epidemiology Supplement were analyzed. The supplement included questions to ascertain knowledge, beliefs, and attitudes and a food frequency questionnaire to ascertain nutrient intake.Statistics Multivariate linear regression modeling was conducted to assess the hypothesized relationships.Results After adjustment for relevant covariates (age, sex, education, total energy, perceived barriers to eating a more healthful diet), knowledge and belief constructs were predictive of dietary behavior. Specifically, fat, fiber, and fruit and vegetable intakes more closely approximated dietary recommendations for persons with more cancer-prevention knowledge. The strength of the associations between these constructs and dietary behavior varied in some cases according to level of education and perceived barriers to eating a healthful diet. Of the perceived barriers to eating a healthful diet, perceived ease of eating a healthful diet was most strongly and consistently predictive of intake.Conclusions Research findings challenge dietetics practitioners to design diet- and health-promotion programs and activities that not only educate the public about the importance of diet to health, but also address barriers to dietary change. 相似文献

Abstract: Spontaneous intracranial hypotension (SIH) is a postural headache syndrome unrelated to dural puncture. Because of the increasing failure of epidural blood patch (EBP) to relieve headache in SIH, we retrospectively investigated the epidemiological features and treatment outcomes in 55 cases of SIH. The study population was stratified by age and sex; continuous variables were compared for differences by t -tests; categorical variables were compared by Chi-squared analysis or Fisher exact tests. Significant differences were identified by P values of 0.05 or less. The mean age of the study population was 44 ± 12 years with a female to male ratio of 1.3:1.0. Men presented with subdural hematomas ( P = 0.001) more often than women. Meningeal enhancement on contrast magnetic resonance imaging (MRI) was the most consistent radiographic finding. Radionuclide cisternography (RC) demonstrated thoracolumbar dural leaks in 16 of 22 patients. EBP failures were more common in patients aged 40 and younger than in older patients ( P = 0.003). Postural headache from SIH was not uniformly responsive to EBP, and had significant comorbidities, especially in men. The management of postural headache in SIH by other techniques to restore brain position and cerebrospinal fluid dynamics should be investigated. 相似文献

In patients with cancer, constipation is a common complication. However, unlike in the general population, the impact of the symptoms of constipation on the quality of life in cancer patients is often greater. More importantly, in patients who are in the more advanced stages of the disease, constipation may also be suggestive of disease progression. Constipation as a symptom in this population is of significant importance as it may lead to life-threatening complications, i.e. bowel perforation due to fecal impaction. Therefore, in this regard, this problem deserves particular attention, as early recognition and management of complications may prevent further physical deterioration. This review aims to provide an overview of the management of constipation in patients with cancer. A symptom-based criteria definition for chronic constipation and prevalence of the problem in cancer patients provides a brief introduction. For the initial assessment and evaluation of constipation in cancer patients, an algorithm is described. The different possible etiologies of constipation in cancer patients are also discussed. Regarding therapeutic management, guidelines and recommendations for the use of different types of laxatives, stool softeners, suppositories and rectal enemas, prokinetic agents, antidepressant medications, and miscellaneous agents are succinctly discussed. Management of fecal impaction and opioid-induced bowel dysfunction are also described. Lastly, a brief overview of the management of acute colonic pseudo-obstruction and surgical or endoscopic options for large bowel obstruction are described. 相似文献

The event of preterm birth represents a significant risk to the equilibrium of the family, often placing the family under significant stress. This paper is intended to assist neonatal nurses in understanding factors related to a family's appraisal of stress and strategies used for coping. Such factors are an important consideration in planning the most effective interventions to support optimal family adaptation to their preterm infant's birth. In identifying the best clinical approaches to supporting a family coping with the event of a preterm birth, nurses need to consider levels of the evidence that supports adoption of clinical intervention strategies. Working to reduce family stress and improve family coping ensures the most optimal home environment for the preterm infant to grow and thrive in after discharge. 相似文献
