THE ASSOCIATION OF FRUIT AND VEGETABLE CONSUMPTION DURING EARLY ADULTHOOD WITH THE PREVALENCE OF CORONARY ARTERY CALCIUM AFTER 20 YEARS OF FOLLOW-UP: THE CORONARY ARTERY RISK DEVELOPMENT IN YOUNG ADULTS (CARDIA) STUDY

BackgroundPrevious studies of the effect of school-based interventions to improve healthy behaviours have had important limitations.ObjectiveTo investigate the effectiveness of a school-based intervention to increase physical activity, reduce sedentary behaviour and increase fruit and vegetable consumption.DesignCluster randomised controlled trial.SettingSixty English primary schools.ParticipantsChildren in year 4 (aged 8–9 years) at recruitment, year 5 (aged 9–10 years) during the intervention and immediate follow-up and year 6 (aged 10–11 years) during 1 year of follow-up.InterventionActive for Life Year 5 (AFLY5) included teacher training, lesson plans, materials for 16 lessons, parent-interactive homework and written materials for school newsletters and parents.Main outcome measuresPrimary outcome measures included accelerometer-assessed levels of physical activity and sedentary behaviour, and child-reported consumption of fruit and vegetables. Secondary outcome measures included child-reported screen viewing; consumption of snacks, high-fat food and high-energy drinks; body mass index; and waist circumference.ResultsWe recruited 60 schools (2221 children). At the immediate follow-up, no difference was found between children in intervention and control schools for any of the three primary outcomes. The intervention was effective on three of the nine secondary outcomes; children in intervention schools reported spending less time screen viewing at weekends [–21 minutes per day, 95% confidence interval (CI) –37 to –4 minutes per day], eating fewer servings of snacks per day (–0.22, 95% CI –0.38 to –0.05 servings of snacks per day) and drinking fewer servings of high-energy drinks per day (–0.26, 95% CI –0.43 to –0.10 servings of high-energy drinks per day) than the children in control schools. The results remained consistent 1 year later. The intervention increased children’s perception of maternal efforts to limit the time they spent screen viewing and children’s knowledge about healthy physical activity and fruit and vegetable consumption, with these two mediators explaining approximately one-quarter of the effect of the intervention on screen viewing. The intervention did not affect other mediators. The cost of implementing the intervention from a provider perspective was approximately £18 per child. Process evaluation showed that AFLY5 was implemented with a high degree of fidelity. Teachers supported the aims of AFLY5, but their views of the programme itself were mixed.LimitationsResponses to parental questionnaires for the economic evaluation were low and we struggled to engage all teachers for the process evaluation. Although the participating schools included a range of levels of socioeconomic deprivation, class sizes and rural and urban settings, we cannot assume that results generalise to all primary schools.ConclusionsAFLY5 is not effective at increasing levels of physical activity, reducing sedentary behaviour and increasing fruit and vegetable consumption in primary school children, but may be effective in reducing time spent screen viewing at weekends and the consumption of snacks and high-energy drinks.Future workOur findings suggest that school-based interventions are unlikely to have a major impact on promoting healthy levels of physical activity and healthy diets in primary school children. We would recommend trials of the effect and cost-effectiveness of more intensive family and community interventions.Trial registrationCurrent Controlled Trials ISRCTN50133740.FundingThis project was funded by the National Institute for Health Research Public Health Research programme and will be published in full inPublic Health Research; Vol. 4, No. 7.

Etiologic Role

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.

Maternal Feeding Practices

Abstract Background Health benefits of fruit and vegetable have been well recognized. However, insufficient consumption of fruit and vegetable is prevalent among toddlers, and has become a global public health issue. Maternal feeding practices are potential factors influencing toddlers’ dietary intake, including fruit and vegetable intake. This study was conducted to explore the influence of maternal feeding practices on toddlers’ fruit and vegetable consumption in Ireland. Methods A follow-up to the DIT-Coombe Hospital birth cohort was conducted. Mothers in the original cohort were invited to participate in the present follow-up study by phone. A questionnaire assessing maternal feeding behavior and the child’s 3-day food diary was sent to mothers who agreed to take part in the present study by post, together with a self-addressed stamped envelope. Results There were 193 mother-children pairs included in the analysis, and the mean age of children was 2.4 (SD 0.7) years old. Toddlers’ mean daily intakes of vegetable and fruit were 67.57 (SD 45.95) g and 213.35 (SD 170.78) g, respectively. Logistic regression analyses showed that maternal practice of breastfeeding for more than 4 weeks was positively associated with fruit (OR = 2.93, 95% CI: 1.29–6.64) and vegetable (OR = 1.95, 95% CI: 1.00–3.81) intake or the contribution of fruit (OR = 2.62, 95% CI: 1.19–5.80) and vegetable (OR = 2.02, 95% CI: 1.02–3.99) to the total diet. Letting the child eat with other family members was associated with high vegetable intake (OR = 5.45, 95%CI: 1.69–17.61) and high contribution of vegetable to total diet (OR = 3.78, 95% CI: 1.04–13.82). Not being too worried about the child’s refusal to eat was positively associated with toddlers’ vegetable intake (OR = 2.10, 95%CI: 1.09–4.05). Conclusions To increase children’s fruit and vegetable intake, and develop good eating habits, parents should eat with their toddlers, be patient and not put much pressure on their children in the context of meal feeding.

And Behavior

Background: Prior research has found poor health among construction workers is related to poor nutrition and low fruit and vegetable consumption. Promoting nutrition knowledge can improve dietary behaviors, but nutrition education among construction workers is limited. We evaluated the effectiveness of nutrition education on fruit and vegetable consumption among construction apprentices. In this pilot evaluative study, 36 construction apprentices enrolled in skill training programs received two 1.5-hour nutrition classes. Twelve questions addressing healthy eating knowledge and behavior were administered at baseline, after intervention, and at three months follow-up. After intervention, daily fruit consumption improved from baseline (mean (s.d.) =1.42 (0.55)) to post intervention (mean (s.d.) =1.72 (0.70)) (p < 0.05) and to three months follow-up (mean(s.d.) =1.94 (0.83)) (p > 0.05). After intervention, daily vegetable consumption improved from baseline (mean (s.d.) =1.67 (0.59)) to post intervention (mean (s.d.) =1.97 (0.74)) (p < 0.05) and to three months follow-up (mean (s.d.) = 2.19 (0.82)) (p > 0.05). Younger construction apprentices showed better healthy eating knowledge at post intervention and three months follow-up (p > 0.05). Working in normal hours showed better healthy eating knowledge at post intervention but not at three months follow up (p > 0.05). Both age groups and working hours did not show significant differences on healthy eating behaviour. Nutrition education implemented as a three-hour session within skill courses may possibly promote fruit and vegetable consumption among construction apprentices. Further research with control group is required to support the findings in this study.
