Dimensions of everyday eating and drinking episodes.

This study sought to gain conceptual understanding of the situational nature of eating and drinking by analyzing 7 consecutive, qualitative 24-h recalls of foods and beverages consumed from 42 US adults who worked in non-managerial, non-professional positions. Participants were purposively recruited to vary in age, gender, occupation, and household composition. For each recall, participants described foods and beverages consumed, location, people present, thoughts and feelings, and activities occurring at that time. Analysis of verbatim transcripts of interviews identified 1448 eating and drinking episodes. Constant comparative analysis of participants' descriptions for episodes resulted in a conceptual framework that characterizes eating and drinking episodes as holistic and as having eight interconnected dimensions (food and drink, time, location, activities, social setting, mental processes, physical condition, recurrence). Each dimension has multiple features that can be used to describe the episodes. In recalling episodes, participants used conventional labels (e.g. "dinner") as well as modified-conventional labels (e.g. "birthday dinner") and uniquely constructed labels (e.g. "unwind time"). Labels provided insights into the dimensions of the episodes. Results suggest approaches for researchers and practitioners who seek to understand how people manage everyday eating at a time when traditional meal patterns are changing.

Chocolate cravings in American and Spanish individuals: biological and cultural influences.

This study investigated relationships of culture and physiology with chocolate cravings. Gender differences in chocolate cravings in Spaniards and Americans were examined using parallel Spanish- and English-version questionnaires administered to 259 undergraduate students at one university in Spain and 306 at one university in the US. Responses were examined separately for men and women in American and Spanish samples using multivariate analyses to control for variables like chocolate availability and cultural involvement (which was described by country of birth, years spent in that country, media use, and cultural identification). Chocolate was the most craved food among all Spanish students, but only female American students. A total of 91% of American women and 59% of American men reported chocolate cravings, and this significant difference persisted when controlling for American cultural involvement. In contrast, 90% of Spanish women versus 78% of Spanish men reported chocolate cravings, but the gender difference was no longer significant when controlling for Spanish cultural involvement. These results do not reject a role of physiology in chocolate cravings, but suggest that American culture encourages disproportionately more chocolate cravings among females than males, and that globalization may have led to a similar craving pattern among Spaniards, although gender differences in cravings are less clear-cut than they are in the US.

Beliefs about whole-grain foods by food and nutrition professionals, health club members, and special supplemental nutrition program for women, infants, and children participants/State fair attendees.

Whole-grain foods are important components of healthful diets that may help prevent chronic diseases. Consumer beliefs that influence consumption of whole grains are poorly understood. This analysis surveyed three groups regarding their beliefs about whole-grain foods. The groups were food and nutrition professionals (n=103), health club members (n=103), and individuals representing various consumer segments of the general population, including participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and state fair attendees (n=68). Most respondents were aware of the term whole-grain foods, but less often reported that they use the term. Bread and cereal were most often named as examples of whole-grain foods. Lack of processing and use of the entire grain were the major reasons a food was perceived as being a whole-grain food. The major benefit of eating whole grains was reported to be fiber intake. Food and nutrition professionals provided more differentiated responses, whereas WIC/state fair participants had fewer and less elaborate responses. Assessing beliefs about whole grains offers insights to nutrition professionals for encouraging healthful food consumption.

Parity and body weight in the United States: differences by race and size of place of residence.

OBJECTIVE: In women, parity has been studied in relation to body weights. This study examined whether and how relationships between parity and body weight differ by race and size of place of residence, adjusting for sociodemographic factors (age, income, education, working status, and marital status) and health behaviors (alcohol consumption, birth control pills, diet, physical activity, and smoking). RESEARCH METHODS AND PROCEDURES: A U.S. national sample of 3398 white and black women from the Third National Health and Nutrition Examination Survey was used to study the relationships using multiple linear regression analysis. RESULTS: The parity-weight relationships varied by race and size of place of residence. After adjusting for the covariates, significant relationships between parity and body weight were found only in black women in metropolitan areas and white women in non-metropolitan areas. Compared with women with no children, white women with two children living in non-metropolitan areas tended to have lower BMIs, whereas black women in metropolitan areas with one or two children showed higher BMIs. DISCUSSION: Overall, the parity-weight relationships in these groups of women were not strong or linear. The parity-weight relationships of black women in non-metropolitan areas warrant further examination.

Religion, social support, fat intake and physical activity.

OBJECTIVE: Most research on diet and exercise has focused on these health behaviours as proximate causes of disease, rather than examine the context of how diet and exercise are developed and maintained. This study examined religion and social support in relationship to fat intake and physical activity. DESIGN, SETTING AND SUBJECTS: Data from surveys of 546 adults aged 17-91 years, residing in one upstate New York county, were analysed. RESULTS: Most relationships between the multiple facets of religion, fat intake and physical activity were not statistically significant. After controlling for demographics and social support, Conservative Protestant women and women specifying an "Other" religious affiliation reported higher fat intakes than did Catholic women. There were no relationships between religion and fat intake in men. In women, religious commitment was associated with greater moderate and vigorous physical activity, whereas in men, divine social support was associated with greater moderate physical activity. Social support did not substantially change the magnitude of the relationships between religion, diet and physical activity. CONCLUSION: Overall, there were few relationships between religion, fat intake and physical activity, suggesting that in contemporary US society religion may play a small role in the context of how diet and exercise are developed and maintained. The limited range of religiosity in the sample, however, may have underestimated the role of religion. Significant relationships between religion and physical activity in women suggest that further research is needed to more clearly delineate religion's relationship with health behaviours.

Qualitative sample extensiveness in health education research.

The use of qualitative methods is increasing in the health education literature, and there is need for more information on these methods and their use. This investigation looks at qualitative sampling practices as reported in the 93 qualitative or mixed-method studies published in Health Education & Behavior from 1980 to 2000. It focuses particularly on the extensiveness of sampling in this research (i.e., the volume and diversity of information collected about the phenomenon of interest). Among these studies, individual interviews averaged 104 +/- 134 informants (range 2 to 720) and 92 +/- 39 minutes. Focused group interviews averaged 10 groups (range 1 to 40) and 90 +/- 25 minutes. Observational studies usually occurred in multiple sites and involved approximately 16 to 24 months of fieldwork. Document analysis extensiveness varied considerably on a variety of indicators. Future qualitative research would benefit from more complete consideration and fuller reporting of sample extensiveness.

Food choices among newly married couples: convergence, conflict, individualism, and projects.

Individuals entering marriage merge their personal food systems to create a joint spousal food system. This investigation examined newly married couples' food choices. Qualitative interviews conducted with 20 couples as they entered marriage and again 1 year later revealed that some reported initial food homogamy, while others had varying degrees of compatibility in food preferences and tolerances. All couples reported some dietary convergence. Convergence was initially symmetrical (similar merging for both partners) or asymmetrical (one partner changed more), and sometimes convergence patterns evolved further. Unresolved food choice negotiations led to food conflicts. Prior food broadening experiences, initial dietary congruity, health/weight philosophies, foodwork, and commensal patterns were conditions shaping couples' food choice negotiations and dietary convergence patterns. Some food individualism persisted for most partners, helping to alleviate food choice conflicts. Food projects occurred when one partner was committed to molding the other's food choices. Overall, food choice negotiations involving both convergence and conflict were important components of marital adjustments that may have later health consequences.

Commensal eating patterns: a community study.

Commensality is eating with other people, and commensal eating patterns reflect the social relationships of individuals. This study examined usual meal partners in commensal units and frequency of eating with others in commensal circles among 663 adults responding to a mailed questionnaire in one community. Meal partner data revealed that most respondents ate alone at breakfast, alone or with co-workers at lunch, and with family members at dinner. Commensal frequency data revealed some eating at the homes of other family members, little eating at friends' homes, and almost no eating at neighbors' homes. Few demographic variations existed in commensal eating, except that unmarried individuals more often ate breakfast and dinner alone and more often ate with friends. These finding suggest that contemporary work-oriented society may lead people to eat alone during the day but share evening meals with family, and that people maintain commensal relationships primarily with family members rather than friends or neighbors. Peoples' social worlds appear to be focused on the nuclear family, and family members are also the people they usually eat with.

Sandwiching it in: spillover of work onto food choices and family roles in low- and moderate-income urban households.

Lower status jobs, high workloads and lack of control at work have been associated with less healthful diets, but the ways through which work is connected to food choices are not well understood. This analysis was an examination of workers' experience of the relationship of their jobs to their food choices. Fifty-one multi-ethnic, urban, low- and moderate-income adults living in Upstate New York in 1995 participated in a qualitative interview study of fruit and vegetable choices and discussed employment and food choices. The workers who participated in this study described a dynamic relationship between work and food choices that they experienced in the context of their other roles and values. These workers presented a relationship that was characterized by positive and negative spillover between their jobs and their ability to fulfill family roles and promote personal health, linked by a spectrum of food choice strategies. Participants' narratives fit into three different domains: characterizations of work and their resources for food choice, strategies used to manage food choices within the constraints of work, and affect related to the negative and positive spillover of these strategies on family roles and on personal food choices. Characterizations of work as demanding and limiting or demanding and manageable differentiated participants who experienced their food choice strategies as a source of guilt and dissatisfaction (negative spillover) from those who experienced food choices as a source of pride and satisfaction (positive spillover). Ideals and values related to food choice and health were balanced against other values for family closeness and nurturing and personal achievement. Some participants found work unproblematic. These findings direct attention to a broad conceptualization of the relationship of work to food choices in which the demands and resources of the work role are viewed as they spill over into the social and temporal context of other roles and values.

Marital status changes and body weight changes: a US longitudinal analysis.

The role of spouse is associated with better health. The dynamics of spousal roles can be represented by marital trajectories that may remain stable or may change by entry into marriage, dissolution of marriage, or death of a spouse. Body weight is an important health-related characteristic that has been found to have mixed relationships with marital status. This analysis examined changes in marital status and body weight in 9043 adults in the US National Health and Nutrition Epidemiological Follow-up Survey (NHEFS), a longitudinal national study that interviewed and measured adults in a baseline assessment and reassessed them again in a follow-up approximately 10 years later. Men's and women's weights were differently associated with marital changes. Women who were unmarried at baseline and married at follow-up had greater weight change than those who were married at both times. Analysis of weight loss and weight gain separately revealed that sociodemographic variables, including marital change, were more predictive of variation in weight loss than weight gain. Unmarried women who married gained more weight than women married at both times. Men who remained divorced/separated and men who became widowed lost more weight than men married at both baseline and follow-up. These findings suggest that changes in social roles, such as entering or leaving marriage, influence physical characteristics such as body weight.

Socio-economic, dietary, activity, nutrition and body weight transitions in South Korea.

OBJECTIVE: Socio-economic development influences many factors that affect health, especially diet and nutrition. This investigation proposes that a system of transitions occur as societies develop, with socio-economic, physical activity, dietary, nutrition and body weight transitions operating in relationship with each other. This model of transitions was examined empirically using South Korea as an example of a nation that has undergone considerable changes. DESIGN: Data were drawn from published government reports: the Korean National Nutrition Survey and annual reports at the national level for the years between 1969 and 1993. The socio-economic transition was assessed by gross national product. The physical activity transition was assessed using annual proportions of the population involved in primary, secondary and tertiary industries, as well as the number of cars and driver's licences. The dietary transition was measured by plant and animal food consumption. The nutrition transition was assessed by percentages of energy from carbohydrate, protein and fat. The body weight transition was measured by body mass index calculated from the average height and weight of adolescents. RESULTS: Results revealed that the transitions were highly correlated as expected, with the socio-economic transition exhibiting major changes. South Koreans tended to decrease their physical activity and plant food consumption, and to increase animal food consumption, percentage of energy from dietary fat and body weight, in relationship to the socio-economic transition. CONCLUSION: Examining a system of transitions on a national level in one country that has undergone rapid economic development may provide a strategy for examining how such transitions operate in other nations.

Maintaining Vegetarian Diets Personal Factors, Social Networks and Environmental Resources.

This study was designed to investigate factors influencing the maintenance of a vegetarian diet. An interpretivist approach and qualitative research methods were used in the study design. Nineteen vegetarians from a metropolitan area in Western New York State were purposefully recruited using snowball sampling to participate in in-depth interviews. Respondents varied in age, gender and type and duration of vegetarian diet, although the sample was predominantly middle-aged, middle-class and female and had ties to community groups. Interview transcripts were analyzed using the constant comparative method of qualitative data analysis. The maintenance of vegetarian diets was supported by personal factors, social networks and environmental resources. Personal factors included: internal beliefs, skills and habits and physical feedback. Social networks included: organized vegetarian groups as well as animal rights, environmental, or health groups supporting vegetarianism and vegetarian friends. Environmental resources, such as the availability of new vegetarian foods in supermarkets and restaurants, facilitated maintenance of vegetarian diets. Respondents perceived that society viewed vegetarianism as increasingly "mainstream," although diet-centred family conflicts were still common. These findings can assist dietitians in developing strategies for working with vegetarian clients by providing better understanding of personal, social and environmental supports for vegetarians' dietary behaviours.

Who we are and how we eat: a qualitative study of identities in food choice.

OBJECTIVE: The study sought to develop a theoretical understanding of identities related to eating. DESIGN: A grounded theory approach and open-ended, in-depth interviews were used to examine identity and eating from the perspectives of adults. PARTICIPANTS: Seventeen middle-class, white adults (nine women, eight men) were purposely recruited to vary in gender, age, household composition, and ways of eating using convenience and snowball sampling. DATA ANALYSIS: Interview transcripts were analyzed using the constant comparative method. RESULTS: Identities involved in participants' food choices related to usual or preferred eating behaviors, personal traits, reference groups, and social categories. Participants varied in the number, type, and complexity of identities involved in eating. Identities were reported to be both stable and dynamic over time and were shaped by participants' life course experiences. Participants varied in the attention they paid to evaluation and monitoring of identities related to eating, the extent to which they enacted identities in eating, and how they managed identity conflicts. IMPLICATIONS: The concept of identity may help researchers understand food choice processes and assist practitioners in recognizing the multiple meanings that people bring to and derive from eating.
