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: Many adults have poor dietary habits and few studies have focused on mechanisms underlying these behaviors. This study examined psychosocial determinants of dietary behavior change in university employes across a 5-month period. Participants completed measures of fruit and vegetable consumption (FVC) and low fat food consumption (LFC) and social cognitive constructs. Multiple regression analyses accounted for a unique proportion of variation in dietary change. Outcome expectations significantly predicted FVC and LFC. Self-efficacy significantly predicted LFC. Goals were not associated with dietary behaviors. Further research into implementation strategies may provide insight into how goals work to bring about change.Frontiers in Public Health 04/2014; 2:23. DOI:10.3389/fpubh.2014.00023

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: 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.Public Health Nutrition 08/2014; DOI:10.1017/S1368980014001487 · 2.48 Impact Factor
