To examine the relationship of cancer prevention-related nutrition knowledge, beliefs, and attitudes to cancer prevention dietary behavior.
Noninstitutionalized US adults aged 18 years and older.
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.
Multivariate linear regression modeling was conducted to assess the hypothesized relationships.
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.
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.
"In time series regression dependent and independent variables are measured over time, and the purpose is to model the existing relationship between these variables through regression methods. Various applications of these models have been reported in literature exploring relationship between mortality and air pollution (Katsouyanni et al. 2009; Wong et al. 2010; Balakrishnan et al. 2011); hospital admissions and air pollution (Peng et al. 2008; Zanobetti et Schwartz 2009; Lall et al. 2011); pollution plumes and breast cancer (Vieira et a. 2005); diet and cancer (Harnack et al. 1997); and mortality and drinking water (Braga et al. 2001). Different time series methods have been used in these studies, i.e. the linear models (Hatzakis et al. 1986) the log-linear models (Mackenbach et al. 1992), the Poisson regression models (Schwartz et al. 2004), and Generalized Additive Models (Dominici 2002; Wood, 2006).

"Sociodemographic variables are included in the model to test for significant effects of marital status and family size. NUTRITION AND HEALTH KNOWLEDGE AND HEALTHY FOOD CHOICES Health researchers and practitioners have shown considerable interest in the measurement of nutrition knowledge as a possible mediator of behavior in the form of dietary decision making and healthy dietary practices (Anderson et al. 1998; Cotugna et al. 1992; Harnack et al. 1997). Thus, the social structural effects outlined above can be expected to work alongside NHK in predicting healthy food choices. "
[Show abstract][Hide abstract] ABSTRACT: This study investigates the influence of family solidarity, community structure, information access, social capital, and socioeconomic status on the extent of nutrition and health knowledge (NHK) among primary household meal planners. In turn, we pose the question: does this knowledge influence dietary decision making? Data are taken from a survey determining socioeconomic impacts of vitamin A fortified peanut butter on Philippine households. Questions on the relationships of nutrition to health were selected to construct a knowledge index on which household respondents could be ranked. We then tested hypotheses regarding what types of individual, family-level, and community structural characteristics would predict performance on this index. The results indicate that the strongest predictors of NHK come from sociological theory related to family solidarity and community centrality, in addition to information accessibility and household income. Our findings also indicate that NHK influences dietary choices with regard to the purchase of a vitamin fortified staple food product, which is essential when addressing nutritional deficiency problems in developing countries.

"Concepts such as enjoyment of exercise and self-efficacy have been repeatedly found to be positively associated with physical activity . Factors related to healthy food consumption include health consciousness and knowledge of the prescribed number of servings, as well as knowledge of diet-disease relationships [35,36]. Specific barriers to exercise in patients with diabetes include perceived difficulty of engaging in exercise and feelings of tiredness . "
[Show abstract][Hide abstract] ABSTRACT: The number of patients with diabetes is increasing. BeweegKuur (Dutch for 'Exercise Therapy') is a Dutch lifestyle intervention which aims to effectively and feasibly promote physical activity and better dietary behaviour in primary health care to prevent diabetes.
The goal of this paper is to present the development process and the contents of the intervention, using a model of systematic health promotion planning. The intervention consists of a 1-year programme for diabetic and prediabetic patients. Patients are referred by their general practitioner (GP) to a lifestyle advisor (LSA), usually the practice nurse or a physiotherapist. Based on specific inclusion criteria and in close collaboration with the patient, an individual exercise programme is designed and supervised by the LSA. This programme can be attended at existing local exercise facilities or (temporarily) under the supervision of a specialized exercise coach or physiotherapist. All participants are also referred to a dietician and receive diet-related group education. In the first pilot year (2008), the BeweegKuur programme was implemented in 7 regions in the Netherlands (19 GP practices and health centres), while 14 regions (41 GP practices and health centres) participated during the second year. The aim is to implement BeweegKuur in all regions of the Netherlands by 2012.
The BeweegKuur programme was systematically developed in an evidence- and practice-based process. Formative monitoring studies and (controlled) effectiveness studies are needed to examine the diffusion process and the effectiveness and cost-effectiveness of the intervention.
