Engaging with healthy eating discourse(s): ways of knowing about food and health in three ethnocultural groups in Canada

The aim of this study was to increase our understanding of how people make sense of healthy eating discourses by exploring the 'ways of knowing' about healthy eating among members of three different ethnocultural groups in Canada: African Nova Scotians, Punjabi British Columbians and Canadian-born European Nova Scotians and British Columbians. Data for this paper come from in-depth, individual interviews with 105 adults where they described their experiences, interpretations, and reasoning used in learning and deciding what to believe and/or reject about healthy eating. Between and within ethnocultural group differences in how people come to know and use practices about healthy eating were examined as they were represented through three broad healthy eating discourses: cultural/traditional, mainstream and complementary/ethical. The discourses represented different ways to interpret the food-health relationship and make sense of the evidence about healthy eating in the everyday experience. Engagement with different discourses led participants to undertake different practices upon themselves in the name of healthy eating. We suggest that each of the discourses has a significant contribution to make in a dialogue about how healthy eating, as part of health and well-being, should be conceptualized by a society.     

Beliefs related to breast health practices: the perceptions of South Asian women living in Canada

Breast cancer is becoming a major concern for many South Asian women. Clinical observations of women from a South Asian community living in Canada revealed an under use of early detection strategies. The purpose of this qualitative ethnoscience study was to examine breast health practices from the perspective of South Asian women to provide a foundation for the development of culturally suitable breast health services for this group. Open-ended interviews were conducted with a convenience sample of 50 South Asian women over the age of 30 who had not been diagnosed with breast cancer. Adequate representation of the main religious groups (i.e. Sikh, Hindu, Muslim and Christian) was ensured through sampling techniques. Analysis of translated interviews involved identification of themes and the development of a taxonomy to represent relationships among emerging cultural themes and domains. Four central domains of beliefs related to breast health practices were identified: beliefs about a woman's calling, beliefs about cancer, beliefs about taking care of your breasts and beliefs about accessing services. These beliefs hold important implications for how health promotion strategies should be structured and offered, In particular, attention must be paid to the language that is used to talk about breast cancer, the importance of the role of the family in women's health decisions and traditions related to using narratives to share information and advice.     

HIV/AIDS-associated beliefs and practices relating to diet and work in southeastern Uganda

To explore beliefs relating to diet, work, and HIV/AIDS among the Busoga of rural southeastern Uganda, a cross-sectional survey of 322 adults was conducted in 2007 in Mayuge district, Uganda. Of these adults, 56 were HIV-infected, 120 had a family member with HIV/AIDS, and 146 were in households without HIV-infected members. More than 74.2% of the adults knew someone with HIV/AIDS, and more than 90% correctly identified transmission modes and prevention methods of HIV. In total, 93.2% believed that a person with HIV should work fewer hours to conserve energy but all the three participant groups reported the same working hours. Also, 91.6% believed that a person with HIV infection should eat special nutritious foods, and the participants with HIV infection reported eating more fruits (p=0.020) and vegetables (p=0.012) than other participants. The participants expressed a consistent set of health beliefs about practices relating to HIV/AIDS.Key words: Acquired immunodeficiency syndrome, Beliefs, Cross-sectional studies, Diet, HIV, Knowledge, attitudes, and practice, Nutrition, Uganda     

Knowledge, Attitudes, Beliefs, and Personal Practices Regarding Colorectal Cancer Screening Among Health Care Professionals in Rural Colorado: A Pilot Survey

ABSTRACT:  Purpose: This study reports the baseline knowledge, attitudes, beliefs, and personal practices of health care professionals regarding colorectal cancer (CRC) screening in the High Plains Research Network (HPRN) of rural Colorado prior to a community-based educational intervention. It also examines the association between health care staff members' knowledge, attitudes, beliefs, and personal practices for CRC screening and patient screening levels by practice. Methods: Surveys were mailed to health care professionals in the HPRN. Participating clinics (n = 21) distributed patient surveys on CRC screening to persons aged ≥50 for a 2-week period in 2006. Results: The survey response rate was 81% for providers (n = 46) and 90% for nursing staff (n = 63). Only 54% of health care professionals knew CRC is a leading cause of cancer deaths. When surveyed on their attitudes toward colon cancer, 92%"strongly agreed" or "agreed" that colon cancer is preventable. About 99% (n = 107) of providers and nurses "strongly agreed" or "agreed" that testing could identify problems before colon cancer starts. Most health care professionals (61%) aged ≥50 years had previously been tested and were up-to-date (52%) with screening. Provider knowledge was significantly associated with higher patient screening (P = .02), but provider attitudes and beliefs were not. Moreover, personal screening practices of health care professionals did not correlate with more patients screened. Conclusion: Background knowledge of CRC among HPRN health care professionals could be improved. The results of this pilot study may help focus effective approaches such as increasing provider knowledge to enhance CRC screening in the relevant population.     

Cancer Prevention-Related Nutrition Knowledge,Beliefs, and Attitudes of U.S. Adults: 1992 NHIS Cancer Epidemiology Supplement

The objective of this study was to describe the cancer prevention-related nutrition knowledge, beliefs, and attitudes of U.S. adults. Data collected for the 1992 National Health Interview Survey Cancer Epidemiology Supplement were ana-lyzed.The Supplement was completed by 12,005 adults aged 18 years and older. Frequency distributions were calculated. Logistic regression analyses were conducted to explore differences in knowledge, beliefs, and attitudes according to selected factors. Most adults (83%) believe that good eating habits may reduce their chances of developing major diseases. Of those who held this belief, 66% named cancer as a disease that might be related to what people eat or drink. Among those who believed cancer to be related to what people eat or drink, eating more fiber (72%), more fruits and vegetables (66%), and less fat (60%) were mentioned most frequently as foods/nutrients that affect cancer risk. Conflicting dietary advice, cost of eating a healthy diet, and social support were the most salient perceived barriers to having a healthful diet. Knowledge, beliefs, and attitudes were found to vary by age, sex, ethnicity, poverty, and education. Findings suggest that, although a moderate majority are aware of the relationship between diet and cancer, fewer are knowledgeable about nutrients/foods that influence risk. Differences found in knowledge, beliefs, and attitudes by various socioeconomic factors suggest that nutrition intervention strategies may need to be targeted and tailored to various population subgroups.     

An exploratory study of attitudes, beliefs and practices related to the interim dietary guidelines for reducing cancer in the elderly

In this pilot study, a self-administered questionnaire was used to assess the health attitudes, beliefs and practices related to each of the Interim Dietary Guidelines for Reducing Cancer Risk (I.D.G.R.C.R.) in a convenience sample of elderly Caucasian subjects (N = 30) over 60 years old. The questionnaire items included personal efficacy, perceived motivators and barriers, and current practices related to the compliance of each of the dietary guidelines. The distributions of responses to the questionnaire items show variations in the subjects' attitudes, beliefs and current dietary practices related to each of the dietary guidelines. Most subjects reported current practice of most guidelines except the guideline of a low fat diet. Most of the time, the subjects perceived one or more motivations to comply with the guidelines of eating fruits and vegetables high in vitamin C, and eating dark green or deep yellow vegetables. Taste and health benefits were shown to be important factors among motivators influencing the compliance to the dietary guidelines. The findings of this exploratory study have direct implications for planning nutrition intervention programs for cancer risk reduction in the elderly.     

Comparing decision making between cancer patients and the general population: thoughts, emotions, or social influence?

This study extends a risk information seeking and processing model to explore the relative effect of cognitive processing strategies, positive and negative emotions, and normative beliefs on individuals' decision making about potential health risks. Most previous research based on this theoretical framework has examined environmental risks. Applying this risk communication model to study health decision making presents an opportunity to explore theoretical boundaries of the model, while also bringing this research to bear on a pressing medical issue: low enrollment in clinical trials. Comparative analysis of data gathered from 2 telephone surveys of a representative national sample (n = 500) and a random sample of cancer patients (n = 411) indicated that emotions played a more substantive role in cancer patients' decisions to enroll in a potential trial, whereas cognitive processing strategies and normative beliefs had greater influences on the decisions of respondents from the national sample.     

Attempting to lose weight: specific practices among U.S. adults

BACKGROUND: Americans spend over $33 billion annually on weight-loss products and services. Although weight-control methods are of considerable public health interest, few national data on weight-loss practices are available. This paper examines the prevalence of specific weight-loss practices among U.S. adults trying to lose weight. METHODS: Data from the 1998 National Health Interview Survey, which was conducted through face-to-face interviews of a nationally representative sample of U.S. adults (n =32,440), were analyzed in 2003. RESULTS: Twenty-four percent of men and 38% of women were trying to lose weight. Attempting weight loss was less common among normal weight (body mass index [BMI]<25 kg/m(2)) people (6% men, 24% women) than overweight (BMI>/=25 to 30 kg/m(2)) people (28%, 49%) or obese (BMI>/=30 kg/m(2)) people (50%, 58%). Among those trying to lose weight, the most common strategies were eating fewer calories (58% men, 63% women); eating less fat (49%, 56%); and exercising more (54%, 52%). Less frequent strategies were skipping meals (11% men, 9% women); eating food supplements (5%, 6%); joining a weight-loss program (3%, 5%); taking diet pills (2%, 3%); taking water pills or diuretics (1%, 2%); or fasting for >/=24 hours (0.6%, 0.7%). Only one third of all those trying to lose weight reported eating fewer calories and exercising more. CONCLUSIONS: Increased efforts are needed among all those trying to lose weight to promote effective strategies for weight loss, including the use of calorie reduction and increased physical activity.     

Nutrition education worksite intervention for university staff: application of the health belief model

OBJECTIVE: To evaluate the efficacy of an 8-week worksite nutrition education intervention for university staff using the Health Belief Model (HBM) to promote healthful dietary behaviors that reduce risks for cardiovascular disease and cancer. DESIGN: 2 3 2 repeated measures baseline/posttest ex post facto research design. PARTICIPANTS: Staff employees were randomly assigned to treatment (n = 28) and control groups (n = 25). INTERVENTION: The intervention focused on specific health beliefs, nutrition knowledge, and dietary practices to demonstrate treatment effect. MAIN OUTCOME MEASURES: Dependent variables were specific health beliefs, nutrition knowledge, and dietary behaviors. Independent variables were demographic characteristics and group assignment. ANALYSES: Tests of parametric assumptions, power analyses, analysis of variance, and Kuder-Richardson and Pearson product-moment coefficients were computed and specificity of treatment effects was assessed. RESULTS: Perceived benefits of healthy nutrition practices and nutrition knowledge related to cardiovascular disease and cancer significantly improved among the treatment participants, P <.001. Treatment group participants also significantly reduced total calories, fat, saturated fat, and cholesterol intake (each P <.001). CONCLUSIONS: The intervention appears to be related to treatment effects and significantly increased nutrition knowledge and decreased energy, fat, saturated fat, and cholesterol intake to levels consistent with national recommendations.     

Asian-Islamic women and breast cancer screening: a socio-cultural analysis.

This article explores religious and socio-cultural issues relevant to breast cancer screening practices among older immigrant Asian-Islamic women in the U.S. Some of the Islamic tenets that facilitate breast cancer screening include cleanliness, prevention and individual responsibility in health promotion, diet and eating habits, and exercise, and those that hinder screening practice include gender and modesty considerations and patriarchal marital beliefs. Socio-cultural barriers include patient-physician communication and beliefs about cancer and cancer prevention. Recommendations to increase knowledge and practice of breast cancer screening within a religious and socio-cultural context are provided.     

Cervical cancer screening among Latinas recently immigrated to the United States

BACKGROUND: Little is known about the cancer screening practices of women whose behavior may place them at a high risk for cervical cancer. We explored factors that influence repeated Pap smear screening among recently immigrated Latinas working in bars also called cantinas. METHODS: Face-to-face interview were administered to 360 women working in 60 cantinas. Participants provided information about their cancer screening practices including the number of Pap smears completed in the 5 years before the interview. A theory-based model proposing that demographic characteristics, cancer screening barriers and facilitators, and psychosocial factors influence repeated Pap smear screening was tested with a hierarchical linear regression. RESULTS: Facilitators of cancer screening (recent visit to a physician and receiving a Pap smear in a clinic) and psychosocial variables (Pap smear beliefs, cancer screening intentions and lack of encouragement) were significantly associated with the total number reported Pap smears (adjusted R2 = 0.31, P < 0.0001). Cervical cancer risk behaviors were not significantly associated with repeated screening. CONCLUSIONS: While risk behaviors did not act as barriers, access to health care measures facilitated repeated Pap smear screening. Psychosocial factors hypothesized to function as antecedents of Pap smear screening appear instead to follow from repeated experience with the examination.     

Nutrition Beliefs and Weight Loss Practices of Lakota Indian Adults

Primary objectives were to describe beliefs about diet and health, weight perceptions, and weight loss practices among Lakota Indian adults. In-person interviews were conducted with a total of 219 adults from two reservations in South Dakota. Overall, 55.5% of the sample was overweight. When asked how they perceived their body weight, 6% felt they were “too thin,” 43.4% thought they were “about right,” and 50.2% felt they were “too fat.” When asked what they were doing about their weight, 74% said they were either trying to lose weight or trying to keep from gaining more weight. Reducing the amount of food eaten (90%), eating more fruits and vegetables (86%), increasing physical activity (84%), and skipping meals (82%) were reported to have been used by most of those who had dieted. Of those who felt they needed to lose weight, 78% said they would join a weight loss program if one were offered. Findings indicate that most Lakota adults are concerned about obesity and are attempting to either lose excess weight or avoid gaining weight. Intervention efforts for this population should focus on providing individuals with guidance on effective strategies for weight loss or obesity prevention. Weight loss programs should include features identified as important by survey participants, such as information on how to fit a healthful diet and exercise into daily life.     

Nutrition and cancer prevention knowledge, beliefs, attitudes, and practices: the 1987 National Health Interview Survey.

This article examines the nutrition and cancer prevention knowledge, beliefs, attitudes, and self-reported dietary changes of a US national probability sample. The data were drawn from the Cancer Control Supplement of the 1987 National Health Interview Survey, which was answered by 22,043 adults. Thirty-five percent of the sample reported that they had made dietary changes in the past 1 to 5 years for health reasons. Respondents reported eating more vegetables, fruit, lower-fat meats, and whole grains/fiber and less high-fat meats, fats, sweets/snacks, salty foods, refined grain products, alcohol, and dairy products. Those who did not make any dietary changes most often said the reason was that they enjoyed the food they were presently eating and did not want to make any changes. More than 90% of the sample agreed that diet and disease were related and 73% knew that diet and cancer were related, yet 44% believed there was nothing a person could do to reduce the risk of getting cancer or didn't know what could be done. In response to open-ended questions about foods that either increase or decrease cancer risk, vegetables, whole grains/fiber, fruit, and lower-fat meats were thought to decrease risk, and high-fat meats, fats, alcohol, sweets/snacks, and additives were thought to increase cancer risk. We found education and income levels to be the major demographic variables that have an impact on cancer prevention knowledge, attitudes, and beliefs. People with lower incomes and at lower educational levels should be targeted for education about cancer risk reduction.     

Asian-Islamic Women and Breast Cancer Screening: A Socio-Cultural Analysis

ABSTRACT

This article explores religious and socio-cultural issues relevant to breast cancer screening practices among older immigrant Asian-Islamic women in the U.S. Some of the Islamic tenets that facilitate breast cancer screening include cleanliness, prevention and individual responsibility in health promotion, diet and eating habits, and exercise, and those that hinder screening practice include gender and modesty considerations and patriarchal marital beliefs. Socio-cultural barriers include patient-physician communication and beliefs about cancer and cancer prevention. Recommendations to increase knowledge and practice of breast cancer screening within a religious and socio-cultural context are provided.     

Modified tobacco use and lifestyle change in risk-reducing beliefs about smoking

BACKGROUND: This study examined beliefs about potential risk-reduction strategies for tobacco users among a large group of young adults. Strategies examined included switching to low-yield cigarettes, replacing cigarettes with cigars, switching from cigarettes to smokeless tobacco, adopting a healthy diet, and engaging in regular exercise. METHODS: One-year longitudinal survey of 36,012 young adults (mean 20.1 years) entering the U.S. Air Force from October 1999 to September 2000. RESULTS: Smokers generally rated the strategies as providing more risk-reduction potential than never smokers or ex-smokers, although the group differences were small. Diet, exercise, and switching to low-yield cigarettes were rated as providing the most health benefits, regardless of smoking status. Smokers who had either changed their diet or exercise to lower their risks from smoking had significantly lower perceived personal risk of developing a tobacco-related disease than other smokers. Smokers who believed that switching to smokeless tobacco would lower the health risks associated with smoking were more likely, while smokers reporting switching to low-yield cigarettes were significant less likely, to quit during a 1-year follow-up period. CONCLUSIONS: Beliefs about the risk-reduction benefits of both changes in tobacco use and health behaviors may impact tobacco use attitudes and practices.     

Knowledge, Attitudes, and Interest in Breast-Ovarian Cancer Gene Testing: A Survey of a Large African-American Kindred with a BRCA1 Mutation

BACKGROUND: This study assessed counseling and testing needs from the perspective of adult members of a large African-American kindred with a BRCA1 mutation. METHODS: Interviews were conducted with 95 male and female kindred members to elicit information on sociodemographics, attitudes toward health care providers, breast cancer screening behaviors, and religious/spiritual beliefs, as well as to evaluate psychological distress, beliefs, knowledge, and attitudes related to genetic testing. RESULTS: Knowledge about breast and ovarian cancer genetics was limited. Adherence to screening recommendations was low among females with no personal breast or ovarian cancer history. The majority (67%) wished to discuss risk factors with a health care provider. Most participants (82%) indicated that they would have a genetic test if it were available. Significant predictors of intent to undergo testing were having at least one first-degree relative with breast and/or ovarian cancer (OR = 5.1; 95% CI = 1.2-20.9) and perceived risk of being a gene carrier > or =50% (OR = 64.3; 95% CI = 5.1-803.9) or reporting that they did not know their risk of being a gene carrier (OR = 10.9; 95% CI = 2.1-57.7). Cited barriers to testing included cost and availability. CONCLUSION: There is a high interest level in genetic testing despite limited knowledge about cancer genetics among these high-risk African Americans. Our study provides information for designing a genetic education and counseling intervention for this and similar families.     

Women worried about their familial breast cancer risk--a study on genetic advice in general practice

AIMS: To ascertain whether women who consulted their GP because they perceived themselves as at increased risk of familial breast cancer were indeed at increased risk, and to evaluate potential strategies for assessing genetic risk of breast cancer in general practice. METHODS: Sixty-seven out of 81 women who had consulted their GP for advice about their possible increased risk of developing breast cancer due to breast cancer in the family were interviewed. Familial breast cancer risk was assessed by a clinical geneticist. This assessment was compared with two recent guidelines for referral for genetic counselling. RESULTS: More than half (52%; n = 35) the women had a relative risk of two and over for developing breast cancer, while another half of these 35 (25%; n = 17) had a relative risk of three and over. All the women (n = 17) with a relative risk of three and over were identified by means of the two current guidelines for referral for genetic counselling, while more than half of the women (61%; n = 11) with a relative risk between two and three were identified. CONCLUSIONS: More than half the women concerned about their familial risk of breast cancer are indeed at increased risk of breast cancer. Current guidelines correctly identify women at high risk. However, doubts about the health gain and feasibility of referral warrant caution, and need further investigation.
