The Efficacy of Behavioral Interventions to Modify Dietary Fat and Fruit and Vegetable Intake: A Review of the Evidence

This study examines the association between rates of change in daily fruit and vegetable intake and in weekly levels of moderate-to-vigorous intensity physical activity (MVPA) over a 15-month period in women following primary treatment completion for breast cancer. Breast cancer survivors (N = 199) self-reported fruit and vegetable intake and wore an accelerometer for 7 consecutive days to measure levels of MVPA on five occasions every 3 months. Multivariate latent growth modeling revealed that the rate of change in fruit and vegetable intake was not associated with the rate of change in levels of MVPA. Baseline (Mean = 3.46 months post-treatment) levels of MVPA were not associated with the rate of change of daily fruit and vegetable intake; likewise, baseline fruit and vegetable intake was not associated with the rate of change in levels of MVPA. Behavioral interventions promoting fruit and vegetable intake should not be assumed to yield concomitant effects in promoting MVPA or vice versa.

Purpose. To determine the stages of change for dietary fat and fruit and vegetable intake of cardiac patients entering a rehabilitation program. Design. A cross-sectional study using a convenience sample of newly admitted cardiac rehabilitation patients. Setting. Department of Pulmonary and Cardiac Rehabilitation, Moses H. Cone Memorial Hospital, Greensboro, North Carolina. Subjects. Subjects (n = 226) were predominantly men, Caucasian, married, smokers with 9 to 12 years of education, and with primary diagnoses of coronary artery bypass graft. Measures. Stages of change and food frequency questionnaires were completed by subjects upon admission to cardiac rehabilitation. Results. Subjects in action and maintenance stages for dietary fat reduction comprised 78.7% of the population. Subjects' percentage of energy from fat decreased linearly from the precontemplation stage (38.8%) to the maintenance stage (30.9%). Eighty-one percent of subjects were in precontemplation/contemplation for increasing fruit and vegetable intake. Daily servings of fruits and vegetables ranged from 2.6 for precontemplation to 5.1 for maintenance subjects. Age, body mass index (BMI), education, and family history for coronary disease were unrelated to stage of change for the dependent variables. Conclusions. Patients were in different stages of change for two nutritional behaviors linked to the same disease. Results support the need to assess patients for food behaviors and apply different educational interventions for each food behavior.

Background:Behavioral interventions for weight-loss have been largely unsuccessful. Exercise is the strongest predictor of maintained weight loss and much of its effects may be from associated changes in psychosocial factors.Methods:Middle-aged, formerly sedentary adults with severe obesity were randomly selected to 6-month treatments of cognitive-behavioral exercise support paired with either standard nutrition education (n = 99) or nutrition change supported by cognitive-behavioral means with an emphasis on self-regulation (n = 101).Results:Overall improvements in self-efficacy and self-regulation for both exercise and managed eating, and mood, were found, with significantly greater improvements associated with the cognitive-behavioral nutrition condition in self-regulation for eating and mood. Change scores trended toward being stronger predictors of increased exercise and fruit and vegetable intake than scores at treatment end. Multiple regression analyses indicated that significant portions of the variance in both increased volume of exercise (R2 = 0.45) and fruit and vegetable intake (R2 = 0.21) were explained by changes in self-regulatory skill usage, self-efficacy, and mood.Conclusions:Cognitive-behavioral methods for improved eating paired with behavioral support of exercise may improve weight loss through effects on the psychosocial factors of self-regulation, self-efficacy, and overall mood more than when standard nutrition education is incorporated.

Purpose. To track the 2-year movement of cardiac rehabilitation patients through the stages of change for dietary fat reduction and increasing fruit and vegetable intake. Design. A cross-sectional, longitudinal evaluation of a convenience sample of cardiac rehabilitation patients. Setting. Department of Pulmonary and Cardiac Rehabilitation, Moses H. Cone Memorial Hospital, Greensboro, North Carolina. Subjects. Subjects (n = 118) were predominately white, overweight, married men with a history of tobacco use. Intervention. Group nutrition education sessions for 12 weeks. Measures. Stage of change assessments for dietary fat reduction and increasing fruit and vegetable intake were performed at the start (baseline), conclusion (3 months), and 2 years after cardiac rehabilitation. Results. Baseline staging demonstrated patients' efforts to reduce dietary fat intake (preparation, 10.2%; action, 35.6%; maintenance, 47.5%). The assessment at 2 years staged 87.3% of the population in the maintenance stage. In contrast, the precontemplation (30.0%), contemplation (7.6%), and preparation (49.2%) stages dominated baseline staging for modifying fruit and vegetable intake. Patients in the precontemplation and contemplation stages increased to 58.5% at 2 years. Conclusions. Cardiac rehabilitation patients are in different stages for two food behaviors linked to the same illness. Results support the appropriateness of nutrition education that emphasizes instrumental information for affecting fat reduction behaviors. Modifying fruit and vegetable intake behaviors is more appropriately addressed with noninstrumental interventions that emphasize health benefits and barriers to change.

Abstract Background In 2015, the Partnership for a Healthier America launched the branded Fruits & Veggies (FNV) Campaign to apply a unique industry-inspired marketing approach to promote fruit and vegetable sales and intake to moms and teens in two US pilot markets: Fresno, California and Hampton Roads, Virginia. The aims of this cross-sectional study were to: 1) assess brand awareness and fruit- and vegetable-related outcomes among FNV Campaign target audiences in the California and Virginia market locations; and 2) examine whether reported awareness of the FNV Campaign was associated with differences in fruit- and vegetable-related cognitive and behavioral outcomes. Methods Data for this cross-sectional study were collected using an online survey administered to a non-probability convenience sample (n = 1604; February–July 2017) of youth aged 14–20 years (n = 744) and moms aged 21–36 years (n = 860) in the two pilot markets. Descriptive statistics were computed and outcomes compared between unaware and aware respondents, controlling for sociodemographic covariates. Multivariate analysis of covariance (MANCOVA) was conducted to assess whether fruit- and vegetable-related attitude, belief, and encouragement outcomes differed by FNV Campaign awareness; logistic regression was used to examine associations between FNV brand awareness and dichotomous variables (fruit- and vegetable-related behavioral intentions, trying new fruits and vegetables); and ANCOVA was used to assess associations with daily fruit and vegetable intake frequency. Results Approximately 20% (n = 315/1604) of respondents reported awareness of the FNV Campaign. Youth that reported awareness of the FNV Campaign (n = 167, 22.4%) had higher intentions to buy (p = 0.003) and eat (p = 0.009) fruits and vegetables than unaware respondents. Mothers that reported awareness of the FNV Campaign (n = 148, 17.2%) reported greater encouragement for friends and family to eat fruits and vegetables (p = 0.013) and were approximately 1.5 times more likely to report trying a new fruit or vegetable (p = 0.04) than mothers unaware of the Campaign. Daily fruit and vegetable intake frequency did not differ by Campaign awareness. Conclusions FNV Campaign awareness was associated with limited but positive short- and intermediate-term cognitive and behavioral outcomes among target audience respondents. These findings can inform future research to enhance understanding and improve the FNV Campaign as it is expanded to new markets nationwide.

Reliable tools to evaluate diet are needed, particularly in life periods such as adolescence in which a rapid rate of growth and development occurs. We assessed the biochemical validity of a self-administered food frequency questionnaire (FFQ) in a sample of Spanish male adolescents using carotenoids and vitamin E and D data. We analyzed data from 122 male adolescents aged 15–17 years of the INMA-Granada birth cohort study. Adolescents answered a 104-item FFQ and provided a non-fasting blood sample. Mean daily nutrient intakes and serum concentration were estimated for main carotenoids (lutein-zeaxanthin, β-cryptoxanthin, lycopene, α-carotene and β-carotene), vitamins E and D and also for fruit and vegetable intake. Pearson correlation coefficients (r) and the percentage of agreement (same or adjacent quintiles) between serum vitamin concentrations and energy-adjusted intakes were estimated. Statistically significant correlation coefficients were observed for the total carotenoids (r = 0.40) and specific carotenoids, with the highest correlation observed for lutein–zeaxanthin (r = 0.42) and the lowest for β-carotene (0.23). The correlation coefficient between fruit and vegetable intake and serum carotenoids was 0.29 (higher for vegetable intake, r = 0.33 than for fruit intake, r = 0.19). Low correlations were observed for vitamin E and D. The average percentage of agreement for carotenoids was 55.8%, and lower for vitamin E and D (50% and 41%, respectively). The FFQ may be an acceptable tool for dietary assessment among male adolescents in Spain.
