The Relationship

Abstract Objectives To determine whether nutrition knowledge is associated with skin carotenoids, as measured by reflection spectroscopy, a valid and objective assessment of fruit and vegetable intake. Methods A convenience sample of undergraduate and graduate students were recruited through flyers, classroom announcements, and email distribution lists at a large public university in California. Nutrition knowledge was assessed with a validated questionnaire. Skin carotenoids were measured with reflection spectroscopy (RS) using a device known as the Veggie MeterTM. Participants completed the nutrition knowledge questionnaire and height, weight, and RS data were collected by trained researchers at a single time-point. Data were collected as part of a larger, on-going study. Pearson's correlation and ordinary least-squares (OLS) regression analysis were used to determine the relationship between nutrition knowledge and skin carotenoids. Results A total of 40 students participated in the study; 72% were female. Nutrition knowledge scores ranged from 13 to 53 with a mean of 37.95 (out of 58 possible), and the mean RS score was 334.0. Skin carotenoids were found to be significantly correlated with nutrition knowledge (r = 0.332; P = 0.036), with 8.7% of variance in RS score explained by nutrition knowledge. Body mass index (BMI) was found to be negatively associated with RS score at P < 0.05; when BMI was incorporated, the proportion of variance in RS score explained by the regression model was 26.9%. Gender was not found to significantly associated with RS score (P = 0.965). Conclusions These preliminary data suggest that nutrition knowledge may be a significant predictor of dietary fruit and vegetable intake when accounting for BMI in university students. Future studies will incorporate additional variables, such as food security status and diet quality to further elaborate on the relationship between nutrition knowledge and behavior.

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.

The Relationship

Background: Increased intake of fruits and vegetables (F/V) may protect against adiposity, but effects on weight have been inconsistent. Our objective was to examine the relationship between fruit and vegetable intake and weight, using direct and indirect measures of dietary intake: self-reported 24-hour recall and serum carotenoid levels. Methods: Participants from the PREMIER lifestyle intervention trial were included in this analysis (n=554). Dietary measures included 24-hour dietary recalls and serum carotenoid levels, from a fasting blood sample. The outcome was weight in pounds. Nested linear mixed models were used to examine the association between F/V and weight. Results: Mean F/V increased from 4.6 (SD 2.4) to 5.6 (SD 3.2) (p=<.01), mean serum carotenoids increased from 53.2 (SD 31.9) to 68.1 (SD 42.5) (p=<.01). At 18 months, participants in the lowest quintile of fruit and vegetable change reported an average intake of 4.42.8 servings of fruits and vegetables, and those in the highest quintile of change reported an average intake of 7.73.2 servings. In a multivariate model adjusting for age, race, gender, intervention, energy, study site, and time, lower body weight was associated with higher F/V intake measured by dietary recall (−0.63 lbs, 95% CI −0.83 to −0.42, per 1 serving increase in F/V) and serum carotenoids (−0.13 lbs, 95% CI −0.15 to −0.11, per 1 ug/dl increase in carotenoids). Results were somewhat attenuated but consistent after additional adjustments for working heart rate, exercise, calories from sugar-sweetened beverages, marital and employment status, and alcohol use . Conclusions: Greater fruit and vegetable consumption was associated with decreased body weight. Results were consistent for both objective and self-reported measures of fruit and vegetable intake.

Background: Older adults report low fruit and vegetable (FV) intake. The lack of objective, field-based assessments of FV intake is a limitation when assessing the effectiveness of interventions. Aim: To examine if self-reported FV intake was correlated with Veggie Meter® scores among low-income older adults. The Veggie Meter® is a portable tool that uses pressure-mediated reflection spectroscopy to estimate skin carotenoid measurements. Methods: A cross-sectional assessment of FV intake, food security, and Veggie Meter® score in low-income older adults was conducted. Bivariate analyses quantified the association between FV intake and Veggie Meter® score. Results: Participants ( n = 154) were mostly female (69.3%), non-white (66.2%) and at risk for food insecurity (65.6%). Mean Veggie Meter® score was 172.3 ± 77.2 and had a small significant positive correlation with FV intake (r= 0.192, p = 0.018). Conclusion: The Veggie Meter® may objectively indicate FV intake. Research to validate the Veggie Meter® in older, diverse populations is needed.

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.
