Association of awareness, intrapersonal and interpersonal factors, and stage of dietary change with fruit and vegetable consumption: a national survey.
ABSTRACT To examine associations of awareness, intrapersonal and interpersonal factors, and stage of change with consumption of fruits and vegetables.
Nationally representative, random digit dial survey conducted in 1997 with a response rate of 44.5%. Psychosocial correlates of fruit and vegetable consumption were assessed using regression analyses.
A total of 2605 adults who were 18 years and older.
Awareness of the "5 A Day for Better Health" program and its message, along with stage of change; taste preferences; self-efficacy; and perceived benefits, barriers, threats, social support, and norms related to fruit and vegetable consumption.
Awareness and intrapersonal and interpersonal factors explained 24% of the variance in fruit and vegetable consumption beyond the 9% explained by demographic characteristics. Knowledge of the 5 A Day message was associated with a 22% increase in fruit and vegetable consumption. Self-efficacy for eating fruits and vegetables and taste preferences (affect) were the factors most consistently and strongly associated with both higher consumption and higher likelihood of being in action or maintenance stages of change. Affect and perceived barriers were more strongly associated with increased vegetables and salad than fruit.
Dietary intervention programs to increase fruit and vegetable consumption should emphasize the 5 A Day message, increased self-efficacy, and ways to make vegetables more palatable and easily accessible. Understanding the factors that influence dietary choices should be used when designing dietary interventions.

ABSTRACT: Low fruit and vegetable (FV) intake is a leading risk factor for chronic disease globally as well as in the United States. Much of the population does not consume the recommended servings of FV daily. This paper describes the development of psychosocial measures of FV intake for inclusion in the U.S. National Cancer Institute's 2007 Food Attitudes and Behaviors Survey. This was a cross-sectional study among 3,397 adults from the United States. Scales included conventional constructs shown to be correlated with fruit and vegetable intake (FVI) in prior studies (e.g., self-efficacy, social support), and novel constructs that have been measured in few- to- no studies (e.g., views on vegetarianism, neophobia). FVI was assessed with an eight-item screener. Exploratory factor analysis, Cronbach's alpha, and regression analyses were conducted. Psychosocial scales with Cronbach's alpha ≥0.68 were self-efficacy, social support, perceived barriers and benefits of eating FVs, views on vegetarianism, autonomous and controlled motivation, and preference for FVs. Conventional scales that were associated (p<0.05) with FVI were self-efficacy, social support, and perceived barriers to eating FVs. Novel scales that were associated (p<0.05) with FVI were autonomous motivation, and preference for vegetables. Other single items that were associated (p<0.05) with FVI included knowledge of FV recommendations, FVI "while growing up", and daily water consumption. These findings may inform future behavioral interventions as well as further exploration of other potential factors to promote and support FVI.PLoS ONE 02/2015; 10(2):e0115017.

ABSTRACT: Objectives: The current study aimed to assess the daily fruits and vegetable consumption and to identify the psychosocial factors as knowledge, barriers and self efficacy associated with fruit and vegetable consumption. Design: A cross-sectional study utilizing a street-based survey method. Setting: The study was carried out at King Faisal University in AL-Hasa, Saudi Arabia. Subjects: Female students aged between 18-25 years (N=960). Outcome measures: Daily fruit and vegetable consumption, anthropometric measurements, psychosocial factors (knowledge, barriers, and self efficacy). Results: Twenty-two percent of the students reported eating five or more servings of fruit and vegetable a day. The total mean of knowledge and the total mean of self efficacy were significant differences between the groups (P= 0.000, P= 0.045; respectively). In a Linear Regression analysis, a greater level of self efficacy of daily fruit and vegetable consumption (β =0.303, SE=0.023, P= 0.000) was significantly predicted for recommended daily of fruit and vegetable consumption, whereas barriers of recommended daily consumption (β=0.055, SE=0.019, P=0.101) and knowledge of recommended daily consumption (β =0.028, SE=0.028, P=0.378) were not predicted to the recommended daily consumption of fruit and vegetable. Conclusion: These findings suggest self efficacy as predict consumption for female students and that self-efficacy is an important variable to consider in dietary change programs for female students.

ABSTRACT: Objective We aimed to identify barriers for meeting the fruit, vegetable and fish guidelines in older Dutch adults and to investigate socio-economic status (SES) differences in these barriers. Furthermore, we examined the mediating role of these barriers in the association between SES and adherence to these guidelines.Design Cross-sectional.Setting Longitudinal Aging Study Amsterdam (LASA), the Netherlands.Subjects We used data from 1057 community-dwelling adults, aged 55-85 years. SES was measured by level of education and household income. An FFQ was used to assess dietary intake and barriers were measured with a self-reported lifestyle questionnaire.Results Overall, 48·9 % of the respondents perceived a barrier to adhere to the fruit guideline, 40·0 % for the vegetable and 51·1 % for the fish guideline. The most frequently perceived barriers to meet the guidelines were the high price of fruit and fish and a poor appetite for vegetables. Lower-SES groups met the guidelines less often and perceived more barriers. The association between income and adherence to the fruit guideline was mediated by ‘perceiving any barrier to meet the fruit guideline’ and the barrier ‘dislike fruit’. The association between income and adherence to the fish guideline was mediated by ‘perceiving any barrier to meet the fish guideline’ and the barrier ‘fish is expensive’.Conclusions Perceived barriers for meeting the dietary guidelines are common in older adults, especially in lower-SES groups. These barriers and in particular disliking and cost concerns explained the lower adherence to the guidelines for fruit and fish in lower-income groups in older adults.Public Health Nutrition 08/2014; 18(05):1-12.
