“…Respondents represent a demographically diverse population and the sample size was large enough (n ¼ 658) to permit detection of associations that may be obscured in smaller studies. Also, our survey instrument was adapted from questionnaires that have been used in other studies 17,21,35,45,46 . We also acknowledge some limitations.…”

Objective: To examine associations of various psychosocial factors with fruit and vegetable intake in African-American adults. Methods: A cross-sectional survey of a population-based sample of 658 AfricanAmericans, aged 18-70 years, in North Carolina. Information was collected on dietrelated psychosocial (predisposing, reinforcing and enabling) factors based on the PRECEDE (Predisposing, Reinforcing, and Enabling Constructs in Educational Diagnosis and Evaluation) planning framework; demographic, lifestyle and behavioural characteristics, and fruit and vegetable intake. Results: The mean participant age was 43.9 years (standard deviation 11.6), 57% were female and 76% were overweight/obese. Participants expressed healthy beliefs regarding many of, but not all, the psychosocial factors. For example, although half of the respondents believed it is important to eat a diet high in fruits/vegetables, only 26% knew that $ 5 daily servings are recommended. The strongest associations of the psychosocial factors with fruit/vegetable intake were for predisposing factors (e.g. belief in the importance of a high fruit/vegetable diet and knowledge of fruit/vegetable recommendations) and one reinforcing factor (social support), with differences between the healthiest and least healthy responses of 0.5-1.0 servings per day. There was evidence of effect modification by gender in associations between psychosocial factors and fruit/vegetable consumption (e.g. self-efficacy was only significant in women), with higher intakes and generally healthier responses to the psychosocial variables in women than men. Conclusions: Interventions to increase fruit/vegetable intake in African-Americans may be more effective if they focus primarily on predisposing factors, such as knowledge, self-efficacy and attitudes, but not to the exclusion of reinforcing and enabling factors. The psychosocial factors that are targeted may also need to be somewhat different for African-American men and women.

“…Several studies suggest that a healthy dietary pattern may be composed of relatively high intakes of fruit, vegetables, reduced-fat dairy products, and fiber (80)(81)(82)(83)(84)(85)(86)(87)(88)(89). Many of these studies show that these dietary patterns are associated with lower risk of disease, as well as lower BMI and waist circumference measurements.…”

Data from the National Health and Nutrition Examination Survey (NHANES) indicate that the trend toward increasing overweight and obesity among MexicanAmericans is continuing. This large population subgroup has a high prevalence of obesity and associated chronic conditions. Ethnic groups have different dietary patterns based on their geographical locations and various cultural influences. We examined the dietary patterns of Mexican-Americans and their association with total and central obesity. We hypothesized that Mexican-American adults following a traditional diet would have a lower prevalence of obesity than those following a more typically American diet. Data from the NHANES 2001-2002 included 835 adults, aged 18 and older. Dietary patterns were defined by cluster analysis of food group variables, expressed as percentage contribution to total energy intake. Obesity was assessed by body mass index (BMI, kg/m²) and central obesity by waist circumference. We defined four dietary patterns, each named after the food groups that were most predominant relative to the other clusters: poultry and alcohol, baked products, traditional foodstuffs (such as tacos, tortillas, etc.), and meat. Surprisingly, we did not identify a "healthy pattern" group in this population, as has been generally observed in other ethnic groups. Contrary to our hypothesis, the traditional diet pattern was associated with higher values of BMI and waist circumference. More details on possible changes within the traditional pattern associated with availability of foods and industrialization, including use of fast food vs. home-prepared Mexican foods, are needed to better understand the observed association with obesity.

“…These perceived obstacles are therefore prevalent and they have been previously reported to represent an important limitation to improving nutrition in the population (Kristal et al, 1995;Trudeau et al, 1998;Anderson et al, 1998;Harnack et al, 1997;Ziebland et al, 1998). Thus, only 20.6% of interviewed subjects from Spain and 18.0% from the rest of the European Union stated that they would not ®nd any dif®culty in adopting a healthy eating.…”

Barriers and benefits of a healthy diet in Spain: comparison with other European member states

et al. 2000

Objective: Our purpose was to identify the main barriers and bene®ts perceived by the European citizens in regard to following a healthy diet and to assess the differences in expected bene®ts and dif®culties between Spain and the remaining countries of the European Union. Design: A cross-sectional study in which quota-controlled, nationally representative samples of approximately 1000 adults from each country completed a questionnaire. Setting: The survey was carried out between October 1995 and February 1996 in the 15 member states of the European Union. Subjects: Participants (aged 15 y and older) were selected and interviewed in their homes about their attitudes towards healthy diets. They were asked to select two options from a list of 22 potential barriers to achieve a healthy diet and the bene®ts derived from a healthy diet. The associations of the perceived bene®ts of barriers with the sociodemographic variables within Spain and the rest of the European Union were compared with the Pearson chi-squared test and the chi-squared linear trend test. Two multivariate logistic regression models were also ®tted to assess the characteristics independently related to the selection of`Resistance to change' among the main barriers and to the selection of`Prevent diseaseastay healthy' as the main perceived bene®ts. Results: The barrier most frequently mentioned in Spain was`Irregular work hours' (29.7%) in contrast with the rest of the European Union where`Giving up foods that I like' was the barrier most often chosen (26.2%). In the multivariate logistic regression model studying resistance to change, Spaniards were less resistant to change than the rest of the European Union. The bene®t more frequently mentioned across Europe was`Prevent diseaseastay healthy'. In the multivariate logistic regression model women, older individuals, and people with a higher educational level were more likely to choose this bene®t. Conclusions: It is apparent that there are many barriers to achieve healthy eating, mostly lack of time. For this reason a higher availability of food in line with the nutrition guidelines could be helpful. The population could have a better knowledge of the bene®ts derived from a healthy diet.
