Wang X, Yin Z, Yang Y, Fu X, Guo C, Pu K, Zang S. Association of plant-based dietary patterns with depression and anxiety symptoms in Chinese older adults: A nationwide study. J Affect Disord 2024; 350:838-846. [PMID: 38278327 DOI: 10.1016/j.jad.2024.01.159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 11/26/2023] [Accepted: 01/14/2024] [Indexed: 01/28/2024]
Abstract
BACKGROUND The associations of plant-based dietary patterns with depression and anxiety symptoms among older adults have not been extensively studied. Therefore, the purpose of this study was to examine these associations in Chinese older adults. METHODS Data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) was employed in the present study. The simplified food frequency questionnaire was used to assess the overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI). The Center for Epidemiologic Studies Depression Scale-10 (CES-D-10) was used to evaluate depression symptoms, and the Generalized Anxiety Disorder Scale-7 (GAD-7) was used to assess anxiety symptoms. This study employed logistic regression and linear regression to examine the associations between plant-based dietary patterns and symptoms of depression and anxiety. RESULTS This study included 11,971 older adults, with a mean age of 83.23 ± 11.10 years. The results indicated that PDI and hPDI were negative associated with depression symptoms (adjusted β -0.09, 95 % CI -0.11, -0.07) (adjusted β -0.09, 95 % CI -0.11, -0.07) and anxiety symptoms (adjusted β -0.03, 95 % CI -0.04, -0.02) (adjusted β -0.04, 95 % CI -0.05, -0.02), while uPDI was positive associated with depression symptoms (adjusted β 0.09, 95 % CI 0.07, 0.11) and anxiety symptoms (adjusted β 0.04, 95 % CI 0.03, 0.05). CONCLUSIONS The findings from this study have the potential to promote healthy dietary patterns in older adults, and may have implications for the prevention and management of depression and anxiety in this population.

Abstract
OBJECTIVE To examine the association of a combined healthy lifestyle in early pregnancy with gestational diabetes mellitus (GDM) risk. DESIGN, SETTING AND POPULATION A Chinese prospective cohort study with 6980 pregnant women. METHODS Individual modifiable lifestyle factors were assessed in early pregnancy and a combined lifestyle score was derived from the sum of the lifestyle factors, with a higher score indicating a healthier lifestyle. The association of a combined healthy lifestyle with GDM risk was examined. MAIN OUTCOME MEASURES Gestational diabetes mellitus was diagnosed in middle pregnancy according to the International Association of Diabetes and Pregnancy Study Group criteria or diagnoses in medical records. RESULTS Overall, 501 (7.2%) pregnant women were diagnosed with GDM. Being physically active (total energy expenditure in upper three quintiles, i.e. ≥100.1 metabolic equivalent of task [MET]-hours/week; odds ratio [OR] 0.76, 95% confidence interval [CI] 0.63-0.92), healthy diet (total intake of vegetables and fruits ≥5 times/day; OR 0.74, 95% CI 0.59-0.94), sufficient sleep (night-time sleep duration ≥7 hours/night; OR 0.66, 95% CI 0.48-0.90) and healthy weight (early-pregnancy BMI <24.0 kg/m2 ; OR 0.57, 95% CI 0.46-0.71) were associated with lower GDM risk. The GDM risk decreased linearly across the combined lifestyle score (Ptrend <0.001): women with 2, 3 and 4 lifestyle factors compared with those with 0-1 factor had 38% (OR 0.62, 95% CI 0.46-0.84), 57% (OR 0.43, 95% CI 0.31-0.58) and 66% (OR 0.34, 95% CI 0.22-0.52) lower risks of GDM, respectively. CONCLUSION A healthy lifestyle in early pregnancy was associated with a substantially lower GDM risk.

[PMID: 37592257 PMCID: PMC10433678 DOI: 10.1186/s12916-023-02974-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 07/06/2023] [Indexed: 08/19/2023] Open
Abstract
BACKGROUND Aging is a dynamic and heterogeneous process that may better be captured by trajectories of aging biomarkers. Biological age has been advocated as a better biomarker of aging than chronological age, and plant-based dietary patterns have been found to be linked to aging. However, the associations of biological age trajectories with mortality and plant-based dietary patterns remained unclear. METHODS Using group-based trajectory modeling approach, we identified distinctive aging trajectory groups among 12,784 participants based on a recently developed biological aging measure acquired at four-time points within an 8-year period. We then examined associations between aging trajectories and quintiles of plant-based dietary patterns assessed by overall plant-based diet index (PDI), healthful PDI (hPDI), and unhealthful PDI (uPDI) among 10,191 participants who had complete data on dietary intake, using multivariable multinomial logistics regression adjusting for sociodemographic and lifestyles factors. Cox proportional hazards regression models were applied to investigate the association between aging trajectories and all-cause mortality. RESULTS We identified three latent classes of accelerated aging trajectories: slow aging, medium-degree, and high-degree accelerated aging trajectories. Participants who had higher PDI or hPDI had lower odds of being in medium-degree (OR = 0.75, 95% CI: 0.65, 0.86 for PDI; OR = 0.73, 95% CI: 0.62, 0.85 for hPDI) or high-degree (OR = 0.63, 95% CI: 0.46, 0.86 for PDI; OR = 0.62, 95% CI: 0.44, 0.88 for hPDI) accelerated aging trajectories. Participants in the highest quintile of uPDI were more likely to be in medium-degree (OR = 1.72, 95% CI: 1.48, 1.99) or high-degree (OR = 1.70, 95% CI: 1.21, 2.38) accelerated aging trajectories. With a mean follow-up time of 8.40 years and 803 (6.28%) participants died by the end of follow-up, we found that participants in medium-degree (HR = 1.56, 95% CI: 1.29, 1.89) or high-degree (HR = 3.72, 95% CI: 2.73, 5.08) accelerated aging trajectory groups had higher risks of death than those in the slow aging trajectory. CONCLUSIONS We identified three distinctive aging trajectories in a large Asian cohort and found that adopting a plant-based dietary pattern, especially when rich in healthful plant foods, was associated with substantially lowered pace of aging.

Abstract
This study aims to explore the interaction between a Chinese version of the Mediterranean-DASH intervention for neurodegenerative delay (cMIND) diet and indoor air pollution and its effect on depression among older adults. This cohort study used 2011-2018 data from the Chinese Longitudinal Healthy Longevity Survey. Participants included 2724 adults aged 65 and older without depression. The Chinese version of the Mediterranean-DASH intervention for neurodegenerative delay (cMIND) diet scores ranged from 0 to 12 based on validated food frequency questionnaire responses. Depression was measured using the Phenotypes and eXposures Toolkit. Cox proportional hazards regression models were used to explore the associations, and the analysis was stratified using the cMIND diet scores. A total of 2724 participants (54.3% males and 45.9% 80 years and older) at baseline were included. Living with severe indoor pollution was associated with a 40% increase in the risk of depression (HR: 1.40, 95% CI: 1.07, 1.82) compared to living without indoor pollution. Indoor air pollution exposure was significantly associated with cMIND diet scores. Participants with a lower cMIND diet score (HR: 1.72, 95% CI: 1.24, 2.38) had a greater association with severe pollution than those with a higher cMIND diet score. The cMIND diet may alleviate depression caused by indoor pollution among older adults.

Abstract
(1) Objective: This study aimed to investigate the relationship between dietary patterns and depression in Chinese older adults. (2) Method: A cohort study was conducted on the relationship between dietary patterns and the risk of depression in older adults based on the China Health and Longevity Longitudinal Survey (CLHLS) from 2011 to 2014. Exploratory factor analysis was used to identify dietary patterns. The relationship between dietary patterns and the risk of depression after four years was examined using logistic regression, and subgroup analysis was carried out to determine whether the association differed by gender. (3) Results: A total of 2873 older adults were included in our cohort study. Three dietary patterns were identified: vegetable-egg-bean-milk pattern, meat-fish pattern, and salt-preserved vegetable-garlic pattern. The vegetable-egg-beans-milk pattern was negatively correlated with the risk of geriatric depression development (adjusted OR = 0.65 (95%CI: 0.49-0.87)), and the salt-preserved vegetable-garlic pattern was positively associated with aged depression risk (adjusted OR = 1.33 (95CI: 1.00-1.77)). The meat-fish pattern was not associated with the risk of depression in older adults. These associations were consistent in both men and women. (4) Conclusions: In this cohort study, the vegetable-egg-beans-milk dietary pattern was associated with lower risk of depression, while the salt-preserved vegetable-garlic dietary pattern was associated with higher risk of depression, and there were no gender differences in these associations.

Abstract
BACKGROUND Betalains are natural red color pigments abundant in red-fleshed dragon fruit (Hylocereus polyrhizus). Recent research has shown that dragon fruit consumption may help improve blood glucose and lipid profile. However, investigations of its cardioprotective properties in human trials, especially in nutritionally achievable amounts, remain nonexistent. OBJECTIVES The aim of this study was to investigate the effects of acute and short-term consumption of dragon fruit on vascular function in a healthy population. METHODS A randomized, double-blind, placebo-controlled, crossover trial was conducted in 19 young, healthy, nonsmoking men and women assigned to consume 24 g whole dragon fruit powder (33 mg betalains) or a nutrient-matched placebo, daily for 14 d. Flow-mediated dilation (FMD), arterial stiffness, and blood pressure (BP) were measured at 0 h, 1 h, 2 h, 3 h, and 4 h and finally at 14 d after daily consumption. RESULTS A total of 18 participants completed the trial. Dragon fruit consumption significantly improved acute FMD at 2 h (+0.8 ± 0.3%, P = 0.01), 3 h (+1.0 ± 0.3%, P = 0.001), and 4 h (+1.3 ± 0.4%, P < 0.001) postconsumption compared with placebo. This effect was sustained up until 14 d (+1.3 ± 0.2%, P < 0.001). Pulse-wave velocity was acutely significantly reduced at 3 h (-0.5 ± 0.2 m/s, P = 0.003), whereas augmentation index (AIx) also improved after 14 d (-7.0 ± 3.3%, P = 0.02) when compared with placebo. No differences were found in either peripheral or central BP across all time points. CONCLUSIONS Acute and short-term consumption of dragon fruit in dietary achievable amounts improved endothelial function and arterial stiffness in healthy individuals. This implies that regular dragon fruit consumption may have a meaningful impact on cardiovascular disease risk likely due to the high betalain content. This trial was registered at ClinicalTrials.gov as NCT03995602.

Abstract
BACKGROUND Air pollution is a risk factor for poor cognitive function, while a plant-based dietary pattern is associated with better cognitive function. We aimed to explore their interaction with cognitive function among older adults. METHODS We used a prospective cohort of old individuals, including 6525 participants of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), aged 65-110 years and with normal cognition at baseline. Air pollution measurement was derived using satellite-derived annual average fine particulate matter (PM2.5) concentrations based on residential locations. Plant-based diet index (PDI) was calculated using survey responses to assess the dietary pattern. Repeated measures of the Mini-Mental State Examination (MMSE) were utilized to assess cognitive function. We applied the Cox proportional hazard regression to explore the associations and further stratified the analysis by PDI. FINDINGS During a median of 5·6-year follow-up, 1537 (23·6%) out of 6525 participants with normal cognition at baseline developed poor cognitive function (MMSE <18). Living in areas with the highest quintile of cumulative PM2.5 was associated with a 46% increase in the risk of developing poor cognitive function (hazard ratio (HR): 1·46, 95% confidence interval (CI): 1·20, 1·77), compared to those living in areas with the lowest quintile. We observed a significant interaction between cumulative PM2.5 and PDI (p-interaction: 0·04), with the corresponding associations of cumulative PM2.5 being more pronounced among participants with lower PDI (HR: 1·68, 95% CI: 1·26, 2·24) than those with higher PDI (HR: 1·28, 95% CI: 0·98, 1·68). INTERPRETATION Plant-based dietary pattern may attenuate detrimental impacts of PM2.5 on cognitive function among older adults. Adherence to the plant-based dietary pattern could be used to prevent adverse neurological effects caused by air pollution, especially in developing regions.

[PMID: 35028515 PMCID: PMC8718853 DOI: 10.1136/bmjnph-2020-000205] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 07/21/2021] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Poor mental well-being is a major issue for young people and is likely to have long-term negative consequences. The contribution of nutrition is underexplored. We, therefore, investigated the association between dietary choices and mental well-being among schoolchildren. METHODS Data from 7570 secondary school and 1253 primary school children in the Norfolk Children and Young People Health and Well-being Survey, open to all Norfolk schools during October 2017, were analysed. Multivariable linear regression was used to measure the association between nutritional factors and mental well-being assessed by the Warwick-Edinburgh Mental Well-being Scale for secondary school pupils, or the Stirling Children's Well-being Scale for primary school pupils. We adjusted all analyses for important covariates including demographic, health variables, living/home situation and adverse experience variables. RESULTS In secondary school analyses, a strong association between nutritional variables and well-being scores was apparent. Higher combined fruit and vegetable consumption was significantly associated with higher well-being: well-being scores were 3.73 (95% CI 2.94 to 4.53) units higher in those consuming five or more fruits and vegetables (p<0.001; n=1905) compared with none (n=739). The type of breakfast or lunch consumed was also associated with significant differences in well-being score. Compared with children consuming a conventional type of breakfast (n=5288), those not eating any breakfast had mean well-being scores 2.73 (95% CI 2.11 to 3.35) units lower (p<0.001; n=1129) and those consuming only an energy drink had well-being scores 3.14 (95% CI 1.20 to 5.09) units lower (p=0.002; n=91). Likewise, children not eating any lunch had well-being scores 2.95 (95% CI 2.22 to 3.68) units lower (p<0.001; 860) than those consuming a packed lunch (n=3744). In primary school analyses, the type of breakfast or lunch was associated with significant differences in well-being scores in a similar way to those seen in secondary school data, although no significant association with fruit and vegetable intake was evident. CONCLUSION These findings suggest that public health strategies to optimise the mental well-being of children should include promotion of good nutrition.

Abstract
BACKGROUND Past research has focused on the relationship between mothers' and children's eating habits, although little is known about fathers as potential agents. The present study aimed to investigate the relationship between fathers' and children's fruit and vegetable (FV) intake in the context of fathers' education level and family income insecurity. METHODS Cross-sectional analysis using baseline data from the multicentre Feel4Diabetes Study were collected in 2016. Participants were parent-dyads (fathers, n = 10,038) and school children (n = 12,041) from six European countries. Socio-demographic and dietary data were collected using questionnaires. Associations were assessed applying the multinomial logistic regression model. RESULTS Overall, European children have low FV intake, especially in Southern European countries (Greece, Spain and Hungary). Children with fathers consuming FV daily were more likely to consume fresh fruit (odds ratio [OR] = 2.75; 95% confidence interval [CI] = 1.95-3.88) and vegetables (OR = 2.55; 95% CI = 1.80-3.60) 1-2 times per day. After adjusting for paternal educational level and family income insecurity significant associations remained for fresh fruit (ORadj = 2.59; 95% CI = 1.82-3.69) and vegetables (ORadj = 1.98; 95% CI = 1.38-2.86). Country differences showed that fathers' educational level and income insecurity might be important factors worth considering for FV intake in Greece. CONCLUSIONS The present study showed that fathers' FV intake was positively associated with children's daily intake of these foods. Implementation of future population-based strategies promoting FV intake not only in mothers, but also in fathers could be an effective public health initiative to increase FV intake in children. Policy-makers should give special attention to families dwelling in Southern European regions.

Abstract
BACKGROUND A diet rich in fruits and vegetables has been suggested to counteract the oxidative stress and inflammation that characterize asthma. We aimed to assess the association between vegetable and fruit diversity consumption and asthma and its related outcomes in school-aged children. METHODS Participants included 647 children (49% females, aged 7-12 years) recruited from 20 public schools across the city of Porto, in Portugal. Vegetable intake and fruit intake were ascertained using a single self-reported 24-hour recall questionnaire. A diversity score was built taking into account the different number of individual vegetables and fruits consumed and categorized into two groups based on the total reported median consumption, which was rounded to the nearest whole number (≤3 and >3, for vegetables; and ≤1 and >1, for fruits). A questionnaire was used to enquire about self-reported medical diagnosis of asthma and respiratory symptoms. Airway inflammation was assessed measuring exhaled fractional nitric oxide concentration (eNO) and was categorized into two groups (<35 and ≥35 ppb). The association between fruit and vegetable diversity and respiratory outcomes was examined using logistic regression models, adjusting for confounders. RESULTS A higher vegetable diversity consumption per day was negatively associated with having self-reported asthma (OR = 0.67; 95% CI 0.47, 0.95), while having a vegetable diversity consumption superior to 3 items per day was negatively associated with levels of eNO ≥ 35 ppb (OR = 0.38; 95% CI 0.16, 0.88) and breathing difficulties (OR = 0.39; 95% CI 0.16, 0.97). CONCLUSION Eating a greater variety of vegetables was associated with a lower chance of airway inflammation and prevalence of self-reported asthma in school children.

Selenium bio-enrichment of Mediterranean fruit juices through lactic acid fermentation. Int J Food Microbiol 2021; 354:109248.

Abstract
This work was carried out to elaborate selenium (Se) bio-enriched fermented Mediterranean fruit juices. To this purpose, pomegranate and table red grape juices were added with sodium selenite (Na2SeO3) and fermented by Levilactobacillus brevis CRL 2051 and Fructobacillus tropaeoli CRL 2034 individually or combined. To better evaluate the effect of selenite addition and starter strain inoculums on the total bacterial community of the fruit juices, fermentation trials were performed with raw and pasteurized fruit juices. No statistical significant differences were observed for total mesophilic microorganisms (TMM) and rod-shaped lactic acid bacteria (LAB) levels among raw and pasteurized juices inoculated with the starter strains, while significant differences between those juices with and without selenite were registered. LAB cocci, Pseudomonadaceae and yeasts were detected only for the raw juice preparations. The dominance of L. brevis CRL 2051 and F. tropaeoli CRL 2034 was confirmed by randomly amplified polymorphic DNA (RAPD)-PCR analysis. After fermentation, pH dropped for all inoculated trials and control raw juices. The soluble solid content (SSC) levels of the raw juices were higher than the corresponding pasteurized trials. The thermal treatment affected consistently yellowness of grape juice trials and redness of pomegranate juices. No microbial Se accumulation was registered for pomegranate juices, while F. tropaeoli CRL 2034 accumulated the highest amount of Se (65.5 μg/L) in the grape juice. For this reason, only trials carried out with raw grape juices were investigated by metagenomics analysis by Illumina MiSeq technology. Non-inoculated grape juices were massively fermented by acetic acid bacteria while Fructobacillus and Lactobacillus (previous genus name of Levilactobacillus) represented the highest operational taxonomy units (OTUs) relative abundance % of the trials inoculated with the starter strains as confirmed by this technique.

Abstract
Background This study investigated the impact of an appearance-based compared with a traditional health-based public health message for healthy eating. Methods A total of 166 British University students (41 males; aged 20.6 ± 1.9 years) were randomized to view either an appearance-based (n = 82) or a health-based (n = 84) fruit promotion poster. Intentions to consume fruit and immediate fruit selection (laboratory observation) were assessed immediately after poster viewing, and subsequent self-report fruit consumption was assessed 3 days later. Results Intentions to consume fruit were not predicted by poster type (largest β = 0.03, P = 0.68) but were associated with fruit-based liking, past consumption, attitudes and social norms (smallest β = 0.16, P = 0.04). Immediate fruit selection was greater following the appearance-based compared with the health-based poster (β = −0.24, P < 0.01), and this effect remained when controlling for participant characteristics (β = −0.21, P < 0.01). Subsequent fruit consumption was greater following the appearance-based compared with the health-based poster (β = −0.22, P = 0.03), but this effect became non-significant on consideration of participant characteristics (β = −0.15, P = 0.13), and was instead associated with fruit-based liking and past consumption (smallest β = 0.24, P = 0.03). Conclusions These findings demonstrate the clear value of an appearance-based compared with a health-based health promotion poster for increasing fruit selection. A distinction between outcome measures and the value of a behavioural measure is also demonstrated.

Abstract
AIM Fruit and vegetables are strongly promoted because of the nutrients they provide; many processed products contain added sugar and sodium. The present study aims to quantify the sugar and sodium content of pre-packaged fruit and vegetable-based products that are available in New Zealand supermarkets. METHODS Nutrition Information Panel data were collected from non-frozen, processed fruit and vegetable products in New Zealand supermarkets (including soups, sauces, jams and spreads, pickles, chutneys and dips, and canned/bottled fruit and vegetables) where fruit and/or vegetables were the majority ingredient(s). RESULTS With the exception of canned/bottled vegetables, more than 60% of products contained added sugar. Per serve, the median sugar content was highest in canned/bottled fruit (17.8 g). More than 75% of soups, vegetable-based sauces, pickles/chutneys and canned/bottled vegetables contained added sodium, with soups (722 mg) recording the highest median values per serve. CONCLUSIONS Consumers need to be aware that although they are encouraged to eat a diet high in fruit and vegetables, there may be large quantities of added sugar and sodium in manufactured fruit and vegetable products that can have significant negative impacts on their health. Government health promotion campaigns encouraging the consumption of fruit and vegetables should be careful to target fresh, frozen and home-prepared foods, and work on educating the public about the lower nutritional quality associated with most processed fruit and vegetable products.

Abstract
BACKGROUND Nurses report inadequacies in health promotion practices. This study investigated attitudes toward being role models for healthy eating, and examined predictors of health promotion attitudes in preregistered nurses. METHOD A questionnaire was completed by 493 preregistered nurses. Measures included health promotion attitudes, healthy lifestyle index, self-esteem, and body satisfaction. RESULTS Preregistered nurses (89.5%) felt that nurses should be role models for health. However, 37% had a negative health promotion attitude and were more likely to be dissatisfied with their body and lead less healthy lifestyles. Most preregistered nurses (96%) felt that delivering health promotion would be a key element of their job and held positive health promotion attitudes. Healthy lifestyle was the most consistent significant predictor of health promotion attitude. CONCLUSION Preregistered nurses with an unhealthy lifestyle and lower self-esteem held a more negative health promotion attitude. Intervention is needed to support preregistered nurses in making healthy lifestyle choices, improving their self-perception and health promotion attitude. [J Nurs Educ. 2017;56(2):94-103.].

Abstract
OBJECTIVE Although fruit and vegetable (F&V) consumption is associated with lower risk of coronary heart disease and stroke, its association with peripheral artery disease (PAD) is less certain. We, thus, sought to characterize F&V intake and investigate the association between F&V consumption and presence of PAD in a large community sample. APPROACH AND RESULTS Self-referred participants at >20 000 US sites who completed medical and lifestyle questionnaires were evaluated by screening ankle brachial indices for PAD (ankle brachial index ≤0.9). Among 3 696 778 individuals, mean age was 64.1±10.2 years and 64.1% were female. Daily consumption of ≥3 servings of F&V was reported by 29.2%. Increasing age, female sex, white race, never smoking, being currently married, physical activity, increasing income, and frequent consumption of fish, nuts, and red meat were positively associated with daily consumption of F&V. After multivariable adjustment, there was a stepwise inverse association between F&V intake and PAD. Participants reporting daily intake of ≥3 servings of F&V had 18% lower odds of PAD than those reporting less than monthly consumption. In unadjusted and multivariable-adjusted models, the inverse association with F&V became stronger as ankle brachial index decreased. When stratified by smoking status, the association was present only among those subjects who currently or formerly smoked tobacco. CONCLUSIONS Our study demonstrates an inverse association of F&V consumption with prevalent PAD and overall low F&V consumption. These observations suggest the need to further efforts to increase F&V consumption and for more rigorous evaluation of the role of F&V in PAD prevention.

A simplified approach to estimating the distribution of occasionally-consumed dietary components, applied to alcohol intake. BMC Med Res Methodol 2016; 16:78. [PMID: 27369373 PMCID: PMC4930587 DOI: 10.1186/s12874-016-0178-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2015] [Accepted: 06/02/2016] [Indexed: 11/29/2022] Open
Abstract
Background Within-person variation in dietary records can lead to biased estimates of the distribution of food intake. Quantile estimation is especially relevant in the case of skewed distributions and in the estimation of under- or over-consumption. The analysis of the intake distributions of occasionally-consumed foods presents further challenges due to the high frequency of zero records. Two-part mixed-effects models account for excess-zeros, daily variation and correlation arising from repeated individual dietary records. In practice, the application of the two-part model with random effects involves Monte Carlo (MC) simulations. However, these can be time-consuming and the precision of MC estimates depends on the size of the simulated data which can hinder reproducibility of results. Methods We propose a new approach based on numerical integration as an alternative to MC simulations to estimate the distribution of occasionally-consumed foods in sub-populations. The proposed approach and MC methods are compared by analysing the alcohol intake distribution in a sub-population of individuals at risk of developing metabolic syndrome. Results The rate of convergence of the results of MC simulations to the results of our proposed method is model-specific, depends on the number of draws from the target distribution, and is relatively slower at the tails of the distribution. Our data analyses also show that model misspecification can lead to incorrect model parameter estimates. For example, under the wrong model assumption of zero correlation between the components, one of the predictors turned out as non-significant at 5 % significance level (p-value 0.062) but it was estimated as significant in the correctly specified model (p-value 0.016). Conclusions The proposed approach for the analysis of the intake distributions of occasionally-consumed foods provides a quicker and more precise alternative to MC simulation methods, particularly in the estimation of under- or over-consumption. The method is readily available to non-technical users in contrast to MC methods whereby the simulation error may be substantial and difficult to evaluate.

Adherence to the Mediterranean Diet and Lifestyle Characteristics of University Students in Cyprus: A Cross-Sectional Survey. J Nutr Metab 2016; 2016:2742841. [PMID: 27293883 PMCID: PMC4884852 DOI: 10.1155/2016/2742841] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2016] [Revised: 03/30/2016] [Accepted: 04/26/2016] [Indexed: 11/24/2022] Open
Abstract
Objective. To assess dietary-related habits among young adults. Design and Setting. Dietary habits were assessed cross-sectionally, using a self-completed questionnaire in 193 students enrolled in public and private universities in Cyprus. Adherence to the Mediterranean diet was evaluated using the validated KIDMED index. BMI was estimated based on weight and height measurements. Results. The mean BMI was 23.31 (±3.98). The mean adherence score to the Mediterranean diet was 6.0 (IQR 4 to 8), with 26.9% of students being classified as high adherers and 21.8% as low adherers to the Mediterranean diet. About 32% of students consumed a second serving of fruit and vegetables more than once a day, whereas 26% reported going more than once a week to a fast-food restaurant and 31% consumed sweets and candy several times a day. On the other hand, 76% of participants reported consumption of at least two dairy products daily and 88% use olive oil at home. The majority consume coffee 2-3 times per day. Conclusions. Results support a shift from traditional healthy diets to more unhealthy eating patterns. However, we also report a high dairy intake and use of olive oil. Tailored-made strategies targeting the young adult population could be warranted.

Abstract
The aim of this study was observing and improving children's eating habits through an edutainment technological platform. A single-group education intervention was carried out in primary schools in Parma and Milano, Italy. A total of 76 children (32 females and 44 males, 8-10 years old) were involved in a 3-month nutritional program including lessons and educational videogames. Intakes of fruits, vegetables, juices and dietary total antioxidant capacity (TAC) were measured using 3-day food diaries before and after the intervention. The daily total consumption of fruit and vegetables increased from 421.8 (320.3) to 484.3 (337.2) g/day (p = 0.016). Consequently, daily dietary TAC increased by 26%, rising from 1.4 (1.3) to 1.6 (1.3) mmol of Trolox equivalents (p = 0.006). The methods and, particularly, the use of technological tools proved to be effective in conducting an educational intervention in children aged 8-10 years old.

Abstract
OBJECTIVE To determine the effect of increasing fruit visibility, adding information and lowering price on fruit purchasing at a university cafeteria in Lima, Peru. DESIGN Quasi-experimental pilot study of a three-phase stepped intervention. In Phase 1, fruit was displayed >3 m from the point of purchase with no additional information. Phase 2 consisted in displaying the fruit near the point of purchase with added health and price information. Phase 3 added a 33% price reduction. The duration of each phase was 3 weeks and phases were separated by 2-week breaks. Primary outcomes were total pieces of fruit and number of meals sold daily. SETTING A university cafeteria in Lima, Peru. SUBJECTS Approximately 150 people, students and non-student adults, who purchased food daily. Twelve students participated in post-intervention interviews. RESULTS Fruit purchasing doubled from Phase 1 to Phase 3 (P<0·01) and remained significant after adjusting for the number of meals sold daily (P<0·05). There was no evidence of a difference in fruit sold between the other phases. Females purchased 100% of the fruit in Phase 1, 82% in Phase 2 and 67% in Phase 3 (P<0·01). Males increased their purchasing significantly between Phase 1 and 3 (P<0·01). Non-student adults purchased more fruit with each phase (P<0·05) whereas students did not. Qualitatively, the most common reason for not purchasing fruit was a marked preference to buy unhealthy snack foods. CONCLUSIONS Promoting fruit consumption by product placement close to the point of purchase, adding health information and price reduction had a positive effect on fruit purchasing in a university cafeteria, especially in males and non-student adults.

Abstract
KEY MESSAGE : Antioxidant activity of seven leafy vegetables and four beans against five reactive oxygen species and reactive nitrogen species was clearly characterized with a protocol using myoglobin as a reporter probe. Antioxidant activity of seven leafy vegetables and four beans against peroxyl radical, hydroxyl radical, hypochlorite ion, and peroxynitrite ion has been measured using myoglobin as a reporter probe (myoglobin method). Conventional DPPH method was also used to evaluate antioxidant activity of the samples. Difference of activity against different reactive oxygen species (ROS) and reactive nitrogen species (RNS) was characterized by plotting the data in a 5-axe cobweb chart. This plot clearly showed the characteristics of the antioxidant activity of the leafy vegetables and the beans. The samples examined in this work were categorized into four groups. (1) The samples showed high antioxidant activity against all ROS and RNS: daikon sprout, spinach, Qing-geng-cai, and onion. (2) The samples showed high antioxidant activity against peroxyl radical: red bean and soy bean. (3) The samples showed high antioxidant against hypochlorite ion: broccoli floret, cabbage, and Chinese cabbage. (4) The samples showed weak antioxidant activity against all ROS and RNS: cowpea and common beans. Our protocol is probably useful to characterize antioxidant activity of the crops of different cultivars, the crops obtained in different growing environments and growing seasons, the crops harvested at different age, and the crops stored in the different conditions, as well as the changes of activity during cooking process of the crops.

Abstract
Background Increased body weight has been associated with an unhealthy diet, low consumption of fruits and vegetables. Our objective was to investigate whether adolescents had low intake of fruits and vegetables, and whether gender, age and education could affect the feeding patterns. Methods A population-based sample of adolescents, aged 12–19 years, were randomly selected in southern Brazil and included in this cross-sectional study. The total daily consumption of fruits, vegetables, rice and beans were investigated in standardized household interviews, using a food frequency questionnaire and questions, being categorized as five or more servings per day as the five-a-day diet. ANOVA, ANCOVA, and modified Poisson regression were used in the analysis. Results Adolescents (n = 568) were included, 49.5% boys, 14.3% had overweight and 8.8% obesity. Approximately 23% of participants consumed five daily servings of fruits and vegetables. It was observed that 36.7% of boys and 31.0% of girls consumed less than one serving of fruit per day, and 58.4% and 44.6%, respectively, consumed less than one serving of vegetables. The consumption of vegetables, fruits, and rice and beans were not independently associated with gender. Overweight was associated with higher intake of five-a-day, independently of confounding factors. Conclusions Adolescents from southern Brazil have lower frequency of consumption of five servings a day of fruits and vegetables combined.

Abstract
OBJECTIVES The purpose of this study is to explore the relationship between the interactions of CYP2C19 gene polymorphisms and several environmental factors and oesophageal squamous cell carcinoma (OSCC). METHODS In a case-control study of OSCC patients (n = 350) and healthy controls (n = 350), we investigated the roles of polymorphism in the CYP2C19 gene by the use of polymerase chain reaction--restriction fragment length polymorphism (PCR - RFLP) analysis. RESULTS The CYP2C19(*)3 AG+AA genotype was significantly more prevalent in OSCC patients (10.0% versus 3.43%; P<0.01). Multiple logistic regression analysis showed drinking (OR: 5.603, 95% CI: 3.431-11.112; P = 0.005) and smoking (OR: 4.341, 95% CI: 3.425-10.241; P = 0.001) was the independent risk factor of OSCC respectively, and there were significant interaction between CYP2C19(*)3 and drinking (OR: 8.747, 95% CI: 6.321-18.122; P = 0.009). CONCLUSIONS The CYP2C19(*)3 polymorphism and OSCC were synergistically and significantly associated in Chinese Han patients.

Abstract
Larger portion sizes (PS) may be inciting over-eating and contributing to obesity rates. Currently, there is a paucity of data on the effectiveness of serving size (SS) guidance. The aims of the present review are to evaluate SS guidance; the understanding, usability and acceptability of such guidance, its impact on consumers and potential barriers to its uptake. A sample of worldwide SS guidance schemes (n 87) were identified using targeted and untargeted searches, overall these were found to communicate various inconsistent and often conflicting messages about PS selection. The available data suggest that consumers have difficulty in understanding terms such as 'portion size' and 'serving size', as these tend to be used interchangeably. In addition, discrepancies between recommended SS and those present on food labels add to the confusion. Consumers generally understand and visualise SS best when expressed in terms of household measures rather than actual weights. Only a limited number of studies have examined the direct impact of SS guidance on consumer behaviour with equivocal results. Although consumers recognise that guidance on selecting SS would be helpful, they are often unwilling to act on such guidance. The challenge of achieving consumer adherence to SS guidance is formidable due to several barriers including chronic exposure to larger PS, distorted consumption norms and perceptions, the habit of 'cleaning one's plate' and language barriers for ethnic minorities. In conclusion, the impact of SS guidance on consumers merits further investigation to ensure that future guidance resonates with consumers by being more understandable, usable and acceptable.

Abstract
Concerns about childhood obesity and chronic disease make most primary care providers willing to address diet. Lack of time and knowledge are cited as obstacles. This article reviews the evidence for selecting one simple message to share with patients. Substantial evidence indicates increasing fruit and vegetable intake can reverse the rising trend is diet-related disease. Eating shared family meals leads to better food choices and lower calories. Recommending family meals and including a fruit or vegetable with every meal and snack, is easy to understand and the health benefits can be significant.

Abstract
AbstractAccurate determination of fruit and vegetable consumption is essential for research that seeks to determine current fruit and vegetable intake patterns, what type and amount of fruit and vegetable consumption is optimal for human health and for evaluating interventions developed to increase such consumption. However, there are many issues that make accurate determination of fruit and vegetable consumption quite difficult. There are many methods used to measure fruit and vegetable intake, but all have limitations. Also, what foods individuals consider to be or to not be fruits or vegetables appear to be quite variable, with such variability often associated with the individual's racial/ethnic background. Researchers and governmental agencies vary with respect to what foods they include and do not include when calculating fruit and vegetable intake. These differences make it difficult to conduct, evaluate and compare studies in this area. The current paper reviews some of the major issues with measuring and determining fruit and vegetable intake.

Abstract
OBJECTIVE To identify and assess healthy eating policies at national level which have been evaluated in terms of their impact on awareness of healthy eating, food consumption, health outcome or cost/benefit. DESIGN Review of policy documents and their evaluations when available. SETTING European Member States. SUBJECTS One hundred and twenty-one policy documents revised, 107 retained. RESULTS Of the 107 selected interventions, twenty-two had been evaluated for their impact on awareness or knowledge and twenty-seven for their impact on consumption. Furthermore sixteen interventions provided an evaluation of health impact, while three actions specifically measured any cost/benefit ratio. The indicators used in these evaluations were in most cases not comparable. Evaluation was more often found for public information campaigns, regulation of meals at schools/canteens and nutrition education programmes. CONCLUSIONS The study highlights the need not only to develop harmonized and verifiable procedures but also indicators for measuring effectiveness and success and for comparing between interventions and countries. EU policies are recommended to provide a set of indicators that may be measured consistently and regularly in all countries. Furthermore, public information campaigns should be accompanied by other interventions, as evaluations may show an impact on awareness and intention, but rarely on consumption patterns and health outcome.

Abstract
BACKGROUND The World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) 1997 recommendations for cancer prevention were meant to apply to children as well as adults. OBJECTIVE To assess the concordance of behaviors and body composition of urban Guatemalan schoolchildren with the tenets of the WCRF/AICR 1997 recommendations. METHODS A survey was conducted involving determination of 24-hour consumption of foods and beverages by a pictorial registry and height and weight measurements in 355 third- and fourth-grade schoolchildren in the western highland city of Quetzaltenango, Guatemala. Based on a previous, exhaustive parsing of the population goal recommendations of the WCRF/AICR 1997 report, 25 subcomponents were identified. Eleven could be evaluated with the survey data collected. Adult population criteria could be applied in seven, whereas four components had unique criteria adapted to this juvenile survey setting. RESULTS The study sample was concordant on seven components-nutrient adequacy, total variety of foods consumed, plant-based diets, body mass index, vegetable and fruit intake, limitation of red meat consumption, and limitation of total fat consumption, and nonconcordant on four-variety of fruits and vegetables consumed, variety of starchy foods consumed, total intake of starchy foods, and limitation of sugar consumption. CONCLUSIONS Educational and public health actions need to be conceived and implemented to further improve the rate of concordance of these 11 components with the WCRF/AICR 1997 recommendations for cancer prevention.

Abstract
BACKGROUND/OBJECTIVES To validate 24 h dietary recall of fruit intake by measuring the total 24 h excretion of 10 different flavonoids in 24 h urine during an intervention with free fruit at workplaces. SUBJECTS/METHODS Employees at workplaces offering a free-fruit program, consisting of daily free and easy access to fresh fruit, and controls employees at workplaces with no free-fruit program were enrolled in this validation study (n=103). Dietary intake was assessed by using a 24 h dietary recall questionnaire at baseline and approximately 5 months later. Ten flavonoids, quercetin, isorhamnetin, tamarixetin, kaempferol, hesperetin, naringenin, eriodictyol, daidzein, genistein, and phloretin, were measured using HPLC-electrospray ionization-MS. RESULTS The 24 h urinary excretion of total flavonoids and the estimated intake of fruits were significantly correlated (r (s)=0.31, P<0.01). The dietary intake of citrus fruits and citrus juices was significantly correlated with total excretion of citrus specific flavonoids (r (s)=0.28, P<0.01), and orange was positively correlated with naringenin (r (s)=0.24, P<0.01) and hesperetin (r (s)=0.24, P<0.01). Phloretin in urine was correlated with apple intake (r (s)=0.22, P<0.01) and also with overall estimated intake of fruit (r (s)=0.22, P<0.01). CONCLUSIONS This study shows that a 24 h dietary recall can be used as a valid estimate of the intake of fruits in agreement with an objective biomarker of fruit intake in free fruit at workplace interventions.

Abstract
OBJECTIVE To examine the sociodemographic, parental and child factors that predict fruit and vegetable consumption in 7-year-old children. DESIGN Diet was assessed using three 1d unweighed food diaries. The child's daily fruit and vegetable consumption was calculated by summing the weight of each type of fruit, fruit juice and vegetable consumed. The various others factors measured were assessed by a questionnaire at different time points. SETTING The Avon Longitudinal Study of Parents and Children (ALSPAC). SUBJECTS A total of 7285 children aged 7 years residing in the south-west of England during 1999-2000. RESULTS Median daily fruit and vegetable consumption (201 g) was below the recommendations for this age group (320 g). Girls ate more fruit and vegetables per unit energy (30.3 g/MJ) than boys (26.7 g/MJ; P =< 0.001). The predictors of fruit and vegetable consumption were mostly similar. Fruit and vegetable consumption was associated with maternal consumption, maternal education status and parental rules about serving fruit/vegetables every day, food expenditure per person and whether the child was choosy about food. Vegetable consumption was also associated with the other characteristics of the child, such as whether the child enjoyed food and whether the child tried a variety of foods. CONCLUSIONS Children are not eating recommended amounts of fruit and vegetables, particularly boys. Consumption of fruit and vegetables appears to be influenced by parental rules about daily consumption and parental consumption and by the child's choosiness. Parent's actions could influence this. These findings may prove useful for those planning healthy eating campaigns for children.

Abstract
Background Fruit and vegetables (F&V) are strongly associated with health. The latest Swedish national dietary survey from a decade ago showed that consumption of F&V was below recommended levels. However, current consumption in different subgroups is not well known. Objective To investigate the consumption of various F&V types in Swedish adults grouped according to sociodemographic factors and self-reported physical activity (PA). Design A cross-sectional survey using a quantitative pen-and-paper or web-based questionnaire in a population-based random sample of adults 18–84 years (final n=1,304; 51%). A self-administered 24-h recall and a food frequency questionnaire (FFQ) were used to measure F&V consumption. Data on gender, age, education level, country of birth, and PA (hours/week) were included as grouping variables. Besides descriptive data, two-sample t-tests and non-parametric tests were performed. A P-value <0.01 was regarded as significant. Results Mean F&V consumption based on the self-administered 24-h recall was close to the recommended five portions/day: 5.4 (99% CI 5.1–5.6) portions/day among women and 4.7 (4.4–5.0) portions/day among men (P<0.001). Also the FFQ showed that women generally consumed more F&V than men did. Consumption was lowest among respondents with ≤ 0.5 h self-reported PA/week (P≤0.001), as well as among men born in Sweden (P=0.006). F&V were consumed in almost equal amounts, and fresh F&V were most popular. Intake of berries and cooked F&V was relatively low. Conclusion The present study shows a relatively high F&V consumption close to the recommended five portions per day. Gender differences still exist. Also PA and country of birth were significantly associated with F&V consumption.

A case-control study on the combined effects of p53 and p73 polymorphisms on head and neck cancer risk in an Italian population. BMC Cancer 2009; 9:137. [PMID: 19426493 PMCID: PMC2686724 DOI: 10.1186/1471-2407-9-137] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2008] [Accepted: 05/08/2009] [Indexed: 02/08/2023] Open
Abstract
Background The purpose of this study is to analyze the combined effects of selected p53 and p73 polymorphisms and their interaction with lifestyle habits on squamous cell carcinoma of the head and neck (SCCHN) risk and progression in an Italian population. Methods Two hundred and eighty-three cases and 295 hospital controls were genotyped for p53 polymorphisms on exon 4 (Arg72Pro), intron 3 and 6, and p73 G4C14-to-A4T14. Their association with SCCHN was estimated using a logistic regression analysis, while a multinomial logistic regression approach was applied to calculate the effect of the selected polymorphisms on SCCHN different sites (oral cavity, oropharynx, hypopharynx and larynx). We performed an haplotype analysis of the p53 polymorphisms, and a gene-gene interaction analysis for the combined effects of p73 G4C14-to-A4T14 and p53 polymorphisms. Results We found a significant increased risk of SCCHN among individuals with combined p73 exon 2 G4A and p53 intron 3 variant alleles (OR = 2.22, 95% CI: 1.08–4.56), and a protective effect for those carrying the p53 exon 4-p53 intron 6 diplotype combination (OR = 0.67; 95% CI: 0.47–0.92). From the gene-environment interaction analysis we found that individuals aged < 45 years carrying p73 exon 2 G4A variant allele have a 12.85-increased risk of SCCHN (95% CI: 2.10–78.74) compared with persons of the same age with the homozygous wild type genotype. Improved survival rate was observed among p53 intron 6 variant allele carriers (Hazard Ratio = 0.51 (95% CI: 0.23–1.16). Conclusion Our study provides for the first time evidence that individuals carrying p53 exon 4 and p53 intron 6 variant alleles are significantly protected against SCCHN, and also shows that an additional risk is conferred by the combination of p73 exon 2 G4C14-to-A4T14 and p53 intron 3 variant allele. Larger studies are required to confirm these findings.

Abstract
OBJECTIVES We monitored changes in self-reported knowledge, attitudes, and behaviors regarding fruit and vegetable consumption in Western Australia prior to and after a healthful-eating campaign. METHODS We obtained telephone survey data from 2854 adults in Perth from Nutrition Monitoring Surveys conducted in 1995, 1998, 2001, and 2004. The "Go for 2&5" fruit and vegetable campaign was implemented from 2002 to 2005. RESULTS We observed changes in knowledge, attitudes, and behaviors regarding fruit and vegetable intake. In 2004, respondents were more likely than in 1995 to report 2 servings of fruit (odds ratio [OR] = 3.66; 95% confidence interval [CI] = 2.85, 4.70) and 5 servings of vegetables (OR = 4.50; 95% CI = 3.49, 5.80) per day as optimal. Despite this, vegetable consumption in 2004 was less than in 1995 (rate ratio = 0.88; 95% CI = 0.82, 0.96; P = .003). Perceived adequacy of vegetable (59.3%) or fruit (34.5%) intake and insufficient time for vegetable preparation (14.3%) were the main barriers. CONCLUSIONS Knowledge of the recommended fruit and vegetable intake increased following the Go for 2&5 campaign. Perceptions of the adequacy of current intake and time scarcity should be considered when designing nutrition interventions.

Abstract
OBJETIVO: Analisar o consumo de frutas, verduras e legumes em mulheres, segundo fatores sócio-demográficos, econômicos e comportamentais. MÉTODOS: A amostra foi constituída de 311 mulheres de três áreas de estudo, do município de Cotia, na área metropolitana de São Paulo, selecionadas por amostragem por conglomerado em dois estágios. O consumo de frutas, verduras e legumes foi avaliado por questionário de freqüência alimentar. Os diferenciais de consumo foram estudados por análise multivariada de regressão logística. RESULTADOS: A chance de baixo consumo de frutas foi maior nas mulheres do bairro pobre, com baixa escolaridade, donas de casa e desempregadas, com baixa renda familiar e tabagistas. Os diferenciais de consumo de verduras foram associados mais à cultura alimentar do que à pobreza: as mais jovens apresentaram chances sensivelmente maiores de baixo consumo de verduras. O tabagismo e o sedentarismo associaram-se ao baixo consumo. Os legumes foram associados tanto ao nível socioeconômico, quanto à cultura alimentar. Foram pouco consumidos pelas mulheres mais jovens e, de um modo geral, por aquelas de pouca escolaridade e baixa renda familiar. Também, o etilismo e o sedentarismo aumentaram as chances de baixo consumo desses alimentos. CONCLUSÃO: O consumo de frutas, verduras e legumes apresentou diferenciais relacionados ao nível socioeconômico, à cultura alimentar e aos hábitos comportamentais.

Abstract
OBJECTIVE To assess consumer understanding of fruit and vegetable serving sizes. DESIGN The Western Australian Health Department launched the Go for 2&5(R) campaign to promote fruit and vegetables in March 2002. The Health & Wellbeing Surveillance System surveyed 1108 adults, aged 16 years and over, between September and November 2002 about what constituted a serving of fruit and of vegetables, their usual daily fruit and vegetables intake, and their recall of the campaign. SETTING The study was undertaken as a part of a public health intervention - social marketing campaign in Western Australia, which had a population of 1 927 000 in 2002. RESULTS Forty-two per cent of respondents knew that the fruit serving size was one piece and only 14.5 % reported the (1/2) cup vegetable serving size. The mean fruit intake was 1.8 (95 % CI 1.7, 1.8) servings/d and the mean vegetable intake was 2.8 (95 % CI 2.7, 3.0) servings/d. Vegetable intake was associated with being female (P = 0.006), increasing age (P < 0.0001), awareness of the campaign (P = 0.031) and knowledge of standard serving size (P = 0.006). Fruit consumption was associated with being female (P = 0.007). Fruit and vegetable intakes were not associated with educational attainment or household income. CONCLUSIONS The Go for 2&5(R) campaign uses a prescriptive message to promote increased consumption of fruit and vegetables. Respondent's knowledge of the standard of serving sizes for fruit and vegetables suggests there is value in separating fruit and vegetable recommendations in messages to encourage increased consumption.

Abstract
BACKGROUND It is important to promote the intake of fruit and vegetables but it is not clear how children interpret the term 'portion'. The aim of this study was to describe portion sizes of various fruits and vegetables selected by primary school children. METHODS A cross-sectional study collected data on children's self-selected portions of fruits and vegetables. Forty-three boys and 52 girls aged 9-10 years attending after school food clubs in Liverpool took part. Children placed a 'portion' of each fruit and vegetable into an empty bowl which was weighed using digital scales accurate to 1 g. RESULTS Mean portion sizes ranged from 126 g for satsumas to 61 g for peas but there were no significant differences between boys and girls. Portions of fruits were larger than portions of vegetables and although there were statistically significant correlations between the portion sizes selected by individual children they were not particularly strong. CONCLUSIONS These children had all taken part in activities promoting '5-a-day' but their perception of 'a portion' varied enormously. It is recommended that children receive targeted activities to help them improve their understanding of what constitutes a 'portion'.

Abstract
PURPOSE As risk-modifiers of alcohol and tobacco effects, metabolic genes polymorphisms were investigated as susceptibility candidates for squamous cell carcinoma of the head and neck (SCCHN). METHODS A total of 210 cases and 245 hospital controls, age and gender matched, were genotyped for CYP1A1, CYP2E1, GSTM1, GSTT1, EPHX1 exons 3 and 4, and NAT2 polymorphisms. A measurement of the biological interaction among two risk factors was estimated by the attributable proportion (AP) due to interaction and its 95% confidence interval (CI). RESULTS SCCHN risk was associated with high-levels of alcohol intake [OR = 3.50 (95%CI: 1.93-6.35) and OR = 6.47 (95%CI: 2.92-14.35) for 19-30 g/day and >30 g/day, respectively], cigarette smoking [OR = 3.47 (95%CI: 1.88-6.41) and OR = 7.65 (95%CI: 4.20-13.90) for 1-25 and >25 pack-years of smoking, respectively] and low-fruit and vegetables consumption (OR = 2.45; 95%CI: 1.53-3.92). No differences were observed for the genotypes or haplotypes distributions among cases and controls, and no biological interaction emerged from gene-gene and gene-environment interaction analyses. An attributable proportion (AP) due to biological interaction of 0.65 (95%CI: 0.40-0.90) was detected for heavy drinkers with a low intake of fruit and vegetables, and an AP of 0.40 (95%CI: 0.10-0.72) resulted forever smokers with low fruit and vegetables consumption. CONCLUSIONS Even in presence of high alcohol consumption or cigarette smoking, a high intake of fruit and vegetables might prevent the development of around one quarter of SCCHN cases. The lack of interaction between the studied polymorphisms and the environmental exposures suggests that chronic consumption of tobacco and alcohol overwhelm enzyme defences, irrespective of genotype.

Abstract
AbstractObjectiveTo examine the effectiveness of two methods of increasing fruit and fruit juice intake in pregnancy: midwives' advice and vouchers exchangeable for juice.DesignPregnant women were randomly allocated to three groups: a control group, who received usual care; an advice group, given advice and leaflets promoting fruit and fruit juice consumption; and a voucher group, given vouchers exchangeable for fruit juice from a milk delivery firm. Dietary questionnaires were administered at ~16, 20 and 32 weeks of pregnancy. Serum β-carotene was measured at 16 and 32 weeks.SettingAn antenatal clinic in a deprived area.SubjectsPregnant women aged 17 years and over.ResultsThe study comprised 190 women. Frequency of fruit consumption declined during pregnancy in all groups, but that of fruit juice increased substantially in the voucher group. Serum β-carotene concentration increased in the voucher group, from 106.2 to 141.8 μmol l− 1in women with measurements on both occasions (P = 0.003), decreased from 120.0 to 99.8 μmol l− 1in the control group (P = 0.005), and was unchanged in the advice group.ConclusionsPregnant women drink more fruit juice if they receive vouchers exchangeable for juice supplied by the milk delivery service. Midwives' advice to eat more fruit has no great effect. Providing vouchers for fruit juice is a simple method of increasing its intake in a deprived population and may be useful for other sections of the community.

Abstract
OBJECTIVE To evaluate the nutritional composition of worksite canteen lunches and to examine the impact of two meal serving systems on employee intake, i.e. buffet style with a fixed price for a varied number of dishes and à la carte style with a separate price for each item on the menu. DESIGN Laboratory technicians observed employees' food selection and collected identical dishes. Food items were weighed separately to calculate the content of fruit and vegetables. The content of protein, fat and ash of each dish was chemically analysed and the carbohydrate and energy content calculated. SETTING Fifteen randomly chosen worksite canteens in Denmark: eight canteens serving buffet style and seven canteens with an à la carte line. SUBJECTS one hundred and eighty randomly chosen employees having lunch at the worksite canteens. RESULTS The average percentage energy from fat was 37 +/- 12 among men and 33 +/- 12 among women. No association was found between the meal serving system and energy intake or macronutrient composition. Eating at canteens serving buffet style, on the other hand, was associated with an increased intake of fruit and vegetables, on average 76 g, and a lower energy density of the food for both genders. CONCLUSION The results highlight the possibilities of promoting healthy food choices in the catering sector and the need to identify models of healthy catering practice. Serving buffet style appears to be a promising strategy in order to increase fruit and vegetable consumption in food served away from home.

Abstract
An investigation was carried out to determine whether there were significant changes in nutrient intake over 17 years of adult life. The Medical Research Council National Survey of Health and Development is a longitudinal study of a nationally representative cohort of singleton births in the UK in 1946. Of this cohort, 1253 survey members provided information on diet recorded in a 5 d diary at age 36 years in 1982, 43 years in 1989 and 53 years in 1999. The outcome measures were mean intakes of energy, macronutrients, minerals and vitamins. There were significant changes in the intake of most nutrients in 1999 compared with previous years. Intakes of fat, Na, Fe and Cu have fallen, but there was a rising trend in the intakes of Ca, P, carotene, thiamin, pyridoxine, folic acid and vitamins C, D and E in both men and women. Additionally, intakes of K, Mg and vitamin K1 have risen in women. There were significant gender differences, women showing a higher percentage rise in the intakes of carotene, riboflavin, folic acid, vitamin C and vitamin E. These changes were related to changes in the consumption of certain key foods, such as the increased consumption of fruit and vegetables and a shift away from whole milk, butter and red meat. Most of these trends are in line with accepted nutritional guidelines. How far these changes are due to consumer choice and real changes in food composition or are due to artefacts inherent in the methodology is discussed.
