AbstractObjectiveAdequate fruit and vegetable intake has been suggested to protect against colorectal cancer. However, several recent prospective studies have reported no association. We therefore examined the association between fruit and vegetable intakes and the risk of colorectal cancer in a prospective cohort study in Japan.DesignBetween June and August 1990, 47 605 Japanese men and women completed a self-administered questionnaire, including a food-frequency questionnaire. We divided the subjects into quartiles based on their self-reported fruit and vegetable consumption. There were 165 colon cancer and 110 rectal cancer incidences identified during 7 years of follow-up, to the end of December 1997. We used Cox proportional hazards models to estimate the relative risk (RR) of developing colorectal cancer according to the level of fruit and vegetable consumption, applying adjustments for potential confounders.ResultsNo statistically significant association was observed between fruit and vegetable consumption and the risk of colorectal cancer. The multivariate RR of colon cancer in the highest quartile of fruit and vegetable intake compared with the lowest was 1.13 (95% confidence interval (CI) 0.73–1.75), the RR for vegetables alone was 1.24 (95% CI 0.79–1.95) and that for fruit alone was 1.45 (95% CI 0.85–2.47). The corresponding multivariate RRs for rectal cancer were 1.12 (95% CI 0.67–1.89), 1.14 (95% CI 0.67–1.93) and 1.41 (95% CI 0.73–2.73).ConclusionsWe found no association between the consumption of fruit and vegetables and the risk of colorectal cancer among the Japanese population.

Abstract:Background: Despite recommendations to increase fruit and vegetable consumption within the UK population, intakes are still too low. In order to stimulate dietary behaviour change the determinants of food choice need to be explored.Objectives:To investigate how the priorities of high consumers of fruit and vegetables differ from those of low consumers, with respect to food choice motivations, and to identify what value high and low consumers place on different aspects of food choice behaviour.Design:A 4-day food diary and a questionnaire, including The Food Choice Questionnaire (FCQ) and a measure of Stage of Change (SOC) for fruit and vegetable consumption, were administered to subjects. Motivation scores from the FCQ were compared with fruit and vegetable intake and SOC data.Subjects:Nine hundred and ninety-eight females, aged 35–69 years, participating in the UK Women's Cohort Study.Results:In a multiple linear regression model, including age, education level and all FCQ motivations, the strongest motivations specifically affecting fruit and vegetable intake were health and natural content. It was found that, for a one point increase (measured on a scale of 0–4) in health and natural content scores, fruit and vegetable consumption increased by 1.11 portions (95% confidence interval (CI) 0.5–1.7) and 0.84 portions (95% CI 0.4–1.3), respectively (P>0.01). The SOC evaluation showed significant associations with portions of fruit and vegetables consumed (P>0.01). Women whose SOC was classed as maintenance phase were found to score higher on health, natural content, weight control and ethical concern factors (P>0.01). These women also scored lower on convenience questions (P>0.01).Conclusion:In this particular group of women the most important motivating factors for food choice, within the high fruit and vegetable consumers, were health and natural content of the food.

BACKGROUND With the increasing use of mobile devices to access the internet and as the main computing system of apps, there is a growing market for mobile health apps to provide self-care advice. Their effectiveness with regard to diet and fitness tracking, for example, needs to be examined. The majority of American adults fail to meet daily recommendations for healthy behavior. Testing user engagement with an app in a controlled environment can provide insight into what is effective and not effective in an app focused on improving diet and exercise. OBJECTIVE We developed Rams Have Heart, a mobile app, to support a cardiovascular disease (CVD) intervention course. The app tracks healthy behaviors, including fruit and vegetable consumption and physical activity, throughout the day. This paper aimed to present its functionality and evaluated adherence among the African American college student population. METHODS We developed the app using the Personal Health Informatics and Intervention Toolkit, a software framework. Rams Have Heart integrates self-reported health screening with health education, diary tracking, and user feedback modules to acquire data and assess progress. The parent study, conducted at a historically black college and university-designated institution in southeastern United States, consisted of a semester-long intervention administered as an academic course in the fall, for 3 consecutive years. Changes were made after the cohort 1 pilot study, so results only include cohorts 2 and 3, comprising a total of 115 students (n=55 intervention participants and n=54 control participants) aged from 17 to 24 years. Data collected over the study period were transferred using the secure Hypertext Transfer Protocol Secure protocol and stored in a secure Structured Query Language server database accessible only to authorized persons. SAS software was used to analyze the overall app usage and the specific results collected. RESULTS Of the 55 students in the intervention group, 27 (49%) students in cohort 2 and 25 (45%) in cohort 3 used the Rams Have Heart app at least once. Over the course of the fall semester, app participation dropped off gradually until exam week when most students no longer participated. The average fruit and vegetable intake increased slightly, and activity levels decreased over the study period. CONCLUSIONS Rams Have Heart was developed to allow daily tracking of fruit and vegetable intake and physical activity to support a CVD risk intervention for a student demographic susceptible to obesity, heart disease, and type 2 diabetes. We conducted an analysis of app usage, function, and user results. Although a mobile app provides privacy and flexibility for user participation in a research study, Rams Have Heart did not improve compliance or user outcomes. Health-oriented research studies relying on apps in support of user goals need further evaluation.

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.

Abstract Objective: To assess the association between adverse childhood experiences (ACE) and behaviours of fruit and vegetable consumption among adults. Design: Cross-sectional analysis. Weighted χ2 and weighted multiple logistic regression analyses were conducted to determine the association between ACE and low fruit and vegetable consumption. Setting: The 2017 Nevada Behavioral Risk Factor Surveillance System. Participants: The sample consisted of 2939 adults. Results: After controlling for potential confounders, exposure to three or more ACE (adjusted OR (AOR) 1·42, 95 % CI 1·02, 2·00) and experiencing parental divorce/separation (AOR 1·50, 95 % CI 1·13, 1·98) were significantly associated with low fruit and vegetable consumption. The study did not find a dose–response relationship between the number of ACE and fruit and vegetable consumption. Conclusions: The study suggests that participants who experienced three or more ACE or parental divorce/separation were at increased risk for low fruit and vegetable consumption. The findings highlight the continuing need for public health interventions and policies that decrease exposure to ACE and increase fruit and vegetable intake among the populations with ACE.

Abstract Background Energy-balance behaviors are precursors to obesity shaped by the practices or strategies that many parents implement. Although key stakeholders to their families, adolescents are rarely considered to report on these obesity-related parenting practices. The aim of this study is to assess the factorial and predictive validity of adolescents’ proxy-report of parents’ obesity-related parenting across four behavioral domains. Methods This study used data from the Family Life, Activity, Sun, Health, and Eating (FLASHE) study. This study tests whether adolescents’ proxy reports about their parents’ obesity-related parenting are significantly associated with parents’ responses on their own obesity-related parenting, as well as whether these reports are significantly associated to parent-adolescent energy-balance behaviors. Factorial validity was assessed using linear regression and Confirmatory Factor Analysis (CFA), whereas predictive validity was assessed using Actor-Partner Interdependence Modeling (APIM). Results Regression results indicated that adolescents’ proxy report is significantly associated with parents’ report of their own parenting in all four domains (β = .59 − .71; p < 0.05). CFA results indicated a final factor structure that loaded significantly onto hypothesized obesity-related parenting domains (β > .30) in both adolescents and parents. APIM results indicated that both parent- (β = .32; p < 0.05) and adolescent-(β = .21; p < 0.05) reported obesity parenting for fruit and vegetable consumption were associated with their own fruit and vegetable intake. In addition, adolescent-reported physical activity parenting was significantly associated with adolescent physical activity (β = 0.23; p < 0.05). Regarding partner effects, only parent-reported parenting for fruit and vegetable consumption were significantly associated with adolescent intake of fruit and vegetables (β = 0.15, p < 0.05) and adolescent-reported physical activity parenting was significantly associated with parental physical activity (β = 0.16, p < 0.05). Neither adolescent nor parent reported parenting were significantly associated with screen time or junk food intake outcomes. Each final obesity-related parenting scale had good internal consistency (a = .74-.85). Conclusions We found that adolescent- and parent-reported obesity-related parenting were significantly associated, while adolescent-reported parenting were more influential of fruit and vegetable intake and physical activity than parent-reported parenting. These findings suggest that adolescent proxy reports may be a valid source of information on obesity-related parenting.

Abstract Background: Even though the existence of inequalities in fruit and vegetable consumption has been well established, it is not clear how it is patterned across intersections of multiple social positions and identities. This study aims to investigate disparities in fruit and vegetable intake between groups at the intersection of education and gender in northern Sweden, and to estimate the discriminatory accuracy of the intersectional groups.Methods: Cross-sectional data from the 2018 Health on Equal Terms survey conducted in four regions in northern Sweden was used (N=21,853). Four intersectional groups were created: high and low educated men, and high and low educated women. Prevalence differences corresponding to joint, referent, and excess intersectional inequalities, were estimated using linear binomial regression for three binary outcome variables: inadequate fruit and vegetable intake combined, inadequate fruit intake, and inadequate vegetable intake. The analysis was adjusted for potential confounders. The discriminatory accuracy of the intersectional groups was estimated by the area under the receiver operating characteristic curve.Results: Low educated men had the highest prevalence of inadequate intake of fruits and vegetables combined (81.4%), fruits (53.5%), and vegetables (54.2%), while high educated women had the lowest (47.7%, 28.6%, and 19.2% respectively). The joint disparities between high educated women and low educated men were both significant and substantial for all outcome variables (34.6 pp, 28.7pp, and 34.9pp respectively, adjusted). They were mostly explained by the two referent disparities for gender and education – the part of the joint disparity explained by differences in gender and education, respectively. An inconsistent direction, magnitude, and significance between outcomes was observed for the excess intersectional disparity - the part of the joint disparity not explained by either referent disparity (-5.5pp, 0.1pp, and 3.9pp respectively, adjusted). The discriminatory accuracy of the intersectional groups was moderate (0.67, 0.64, and 0.66 respectively).Conclusion: An intersectional approach can provide a more detailed view of inequalities in fruit and vegetable consumption between groups combining several social positions. The moderate discriminatory accuracy observed here suggests that interventions and policies aiming to reduce diet inequalities should not solely be targeted at certain groups, but also be universal.

Background: The few established risk factors for non-Hodgkin lymphoma (NHL) exhibit considerable heterogeneity by NHL subtype and suggest an etiologic role for factors with immune- or inflammation-modulating properties, or which otherwise influence lymphocyte proliferation and survival. Epidemiologic evidence supports a potential inverse association for fruit and vegetable intake and NHL risk, but with limited subtype-specific evidence. Glucosinates and indole-3-carbinol, both found in cruciferous vegetables, may mediate tumor suppressive effects, including anti-inflammatory and anti-proliferation effects or restoration of phosphatase and tensin homolog (PTEN), a known tumor suppressor frequently down-regulated in cancer cells. We conducted a prospective study to further elucidate the etiologic role of fruit and vegetable consumption for NHL and its most common histologic subtypes. Methods: We followed 47,971 men in the Health Professionals Follow-Up Study (HPFS; 1986-2012) and 77,115 women in the Nurses' Health Study (NHS; 1984-2012) with baseline information on diet and no baseline history of cancer. We queried diet every four years using validated food-frequency questionnaires. We calculated fruit and vegetable consumption, in broad categories and for specific food groups, by summing the intake of individual foods excluding fruit juices, potatoes and legumes. Incident NHL diagnoses were first self-reported in study questionnaires then confirmed by review of medical records. We classified histologic subtypes according to the World Health Organization (WHO) and International Lymphoma Epidemiology (InterLymph) Consortium guidelines. We analyzed all NHL (in aggregate) and separate endpoints of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, other B-cell NHL and T-cell NHL. We used multivariate Cox proportional hazards regression adjusting for potential confounding variables to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association of various fruit and vegetable intake variables with risk of each NHL endpoint. Those intake variables were based on the pre-diagnosis questionnaire returned most recent to NHL diagnosis and modeled as continuous variables in increments of one serving/day. Results: During 2,747,939 person-years of follow-up, we confirmed 1,732 incident NHL cases (986 women, 746 men). In preliminary multivariable-adjusted analyses, no fruit and vegetable intake variable was significantly associated with risk of all NHL (Table 1). Each additional serving/day of all, green leafy, beta carotene rich and lycopene rich vegetables was significantly associated with a 15%-45% lower risk of DLBCL per serving/day but not with other NHL subtypes; cruciferous and lutein rich vegetable intakes had a suggestive but statistically non-significant inverse association with several B-cell NHL subtypes (Table 1). Other associations were only weakly suggestive or null. Conclusions: In this prospective investigation, preliminary findings suggest a modest reduction of risk of several individual B-cell NHL subtypes, including statistically significantly lower risks of DLBCL, with increasing intake of green and antioxidant rich vegetables. These findings warrant further exploration and confirmation in other study populations. We note that this abstract reports preliminary findings; ongoing analyses will extend the follow-up period, add a third large cohort (NHS II) and assess potential reverse causation, explore sex- and subtype-related heterogeneity and test for non-linearity of observed associations. If confirmed, these results will contribute to evidence-based prevention strategies for NHL and further support general health recommendations concerning benefits of fruit and vegetable intake. Disclosures No relevant conflicts of interest to declare.

AbstractThe present review provides an investigation into the food choice decisions made by individuals in relation to fruit and vegetable consumption. A comprehensive body of evidence now exists concerning the protective effect of fruit and vegetables against a number of diseases, particularly cardiovascular disease and certain forms of cancer. Current UK recommendations are to increase intakes of fruit and vegetables to 400 g/person per d. In the main body of the review the factors that affect food choice decisions of adults in relation to fruit and vegetable consumption are studied, following a suggested framework of food choice. Factors covered include sensory appeal, familiarity and habit, social interactions, cost, availability, time constraints, personal ideology, media and advertising and health. The content of the review shows just how complex the food choice process can be. Health promotion techniques can be better targeted towards certain groups of individuals, all holding similar sets of values, when making food choice decisions. Food choice, in relation to fruit and vegetable intake, needs to be studied in more depth, in order to provide effective nutrition education programmes, in particular the sets of priorities that different sub-groups of the population consider when making food choice decisions.

The aim of the present study was to evaluate the association between parenting styles and own fruit and vegetable consumption among Portuguese mothers of school children. A cross-sectional study was performed in Portugal as part of the Pro Children cross-sectional European survey. Portuguese mothers (n 1601) of 11–13-year-old school children were included in the present study. A self-administered questionnaire was developed to assess fruit and vegetable consumption as well as the parenting styles. Fruit and vegetable consumption was assessed by a validated FFQ. Parenting styles based on two dimensions – strictness and involvement – were classified into authoritative, authoritarian, indulgent and neglectful. The higher mean intakes of fruit, vegetables and total fruit and vegetables were observed for mothers classified as indulgent, whereas the lower mean intakes were observed for mothers classified as neglectful. Differences in intake among parenting styles were significant for fruit, vegetables and total fruit and vegetables. When partial correlations were calculated between the two dimensions, strictness and involvement (controlled one for the other), and intakes, only involvement was positively associated with fruit, vegetables and total fruit and vegetable intake. Findings from the present study show that fruit and vegetable consumption of Portuguese mothers of school children seems to be related to their own parenting styles, especially with the dimension involvement. Future interventions to promote fruit and vegetable intake should take into account these variables.
