The role of food parcel use on dietary intake: perception of Dutch food bank recipients:a focus group study

OBJECTIVE: To gain insight in Dutch food bank recipients' perception on the content of the food parcels, their dietary intake and how the parcels contribute to their overall dietary intake. DESIGN: Eleven semi-structured focus group discussions were conducted. Focus group topics were based on Andersons food insecurity definition: the lack of availability of nutritionally adequate foods and the assured ability to acquire foods in socially acceptable ways. Data were coded and analysed with Atlas.ti 7.0 software, using the framework approach. SETTING: Seven food banks throughout the Netherlands. PARTICIPANTS: A total of 44 Dutch food bank recipients. RESULTS: Food bank recipients were not always satisfied with the amount, quality, variation and type of foods in the food parcel. For the participants who could afford to, supplementing the food parcel was reported as main reason for buying foods, and price was the most important aspect in selecting these foods. Participants were not satisfied with their dietary intake; they mainly reported not having enough to eat. The content of the food parcel importantly influenced participants' overall dietary intake. Finally, participants reported struggling with their feelings of dissatisfaction, while also being grateful for the foods they receive. CONCLUSIONS: This study suggests that, despite their best efforts, food banks are not meeting food bank recipients' needs. Our results provide valuable directions for improving the content of the food parcels by increasing the quantity, quality and variation in the foods supplied. Whether this also improves the dietary intake of recipients needs to be determined

Adenovirus-5-Vectored P. falciparum Vaccine Expressing CSP and AMA1. Part B: Safety, Immunogenicity and Protective Efficacy of the CSP Component

Background: A protective malaria vaccine will likely need to elicit both cell-mediated and antibody responses. As adenovirus vaccine vectors induce both these responses in humans, a Phase 1/2a clinical trial was conducted to evaluate the efficacy of an adenovirus serotype 5-vectored malaria vaccine against sporozoite challenge.\ud \ud Methodology/Principal Findings: NMRC-MV-Ad-PfC is an adenovirus vector encoding the Plasmodium falciparum 3D7 circumsporozoite protein (CSP). It is one component of a two-component vaccine NMRC-M3V-Ad-PfCA consisting of one adenovector encoding CSP and one encoding apical membrane antigen-1 (AMA1) that was evaluated for safety and immunogenicity in an earlier study (see companion paper, Sedegah et al). Fourteen Ad5 seropositive or negative adults received two doses of NMRC-MV-Ad-PfC sixteen weeks apart, at 1x1010 particle units per dose. The vaccine was safe and well tolerated. All volunteers developed positive ELISpot responses by 28 days after the first immunization (geometric mean 272 spot forming cells/million[sfc/m]) that declined during the following 16 weeks and increased after the second dose to levels that in most cases were less than the initial peak (geometric mean 119 sfc/m). CD8+ predominated over CD4+ responses, as in the first clinical trial. Antibody responses were poor and like ELISpot responses increased after the second immunization but did not exceed the initial peak. Pre-existing neutralizing antibodies (NAb) to Ad5 did not affect the immunogenicity of the first dose, but the fold increase in NAb induced by the first dose was significantly associated with poorer antibody responses after the second dose, while ELISpot responses remained unaffected. When challenged by the bite of P. falciparum-infected mosquitoes, two of 11 volunteers showed a delay in the time to patency compared to infectivity controls, but no volunteers were sterilely protected.\ud \ud Significance: The NMRC-MV-Ad-PfC vaccine expressing CSP was safe and well tolerated given as two doses, but did not provide sterile protection

Dutch food bank parcels do not meet nutritional guidelines for a healthy diet

Nutritional intakes of food bank recipients and consequently their health status largely rely on the availability and quality of donated food in provided food parcels. In this cross-sectional study, the nutritional quality of ninety-six individual food parcels was assessed and compared with the Dutch nutritional guidelines for a healthy diet. Furthermore, we assessed how food bank recipients use the contents of the food parcel. Therefore, 251 Dutch food bank recipients from eleven food banks throughout the Netherlands filled out a general questionnaire. The provided amounts of energy (19 849 (sd 162 615) kJ (4744 (sd 38 866) kcal)), protein (14·6 energy percentages (en%)) and SFA (12·9 en%) in a single-person food parcel for one single day were higher than the nutritional guidelines, whereas the provided amounts of fruits (97 (sd 1441) g) and fish (23 (sd 640) g) were lower. The number of days for which macronutrients, fruits, vegetables and fish were provided for a single-person food parcel ranged from 1·2 (fruits) to 11·3 (protein) d. Of the participants, only 9·5 % bought fruits and 4·6 % bought fish to supplement the food parcel, 39·4 % used all foods provided and 75·7 % were (very) satisfied with the contents of the food parcel. Our study shows that the nutritional content of food parcels provided by Dutch food banks is not in line with the nutritional guidelines. Improving the quality of the parcels is likely to positively impact the dietary intake of this vulnerable population subgroup

Influence of weight reduction on blood pressure: a meta-analysis of randomized controlled trials

Increased body weight is a strong risk factor for hypertension. A meta-analysis of randomized controlled trials was performed to estimate the effect of weight reduction on blood pressure overall and in population subgroups. Twenty-five randomized, controlled trials (comprising 34 strata) published between 1966 and 2002 with a total of 4874 participants were included. A random-effects model was used to account for heterogeneity among trials. A net weight reduction of -5.1 kg (95% confidence interval [CI], -6.03 to -4.25) by means of energy restriction, increased physical activity, or both reduced systolic blood pressure by -4.44 mm Hg (95% CI, -5.93 to -2.95) and diastolic blood pressure by -3.57 mm Hg (95% CI, -4.88 to -2.25). Blood pressure reductions were -1.05 mm Hg (95% CI, -1.43 to -0.66) systolic and -0.92 mm Hg (95% CI, -1.28 to -0.55) diastolic when expressed per kilogram of weight loss. As expected, significantly larger blood pressure reductions were observed in populations with an average weight loss >5 kg than in populations with less weight loss, both for systolic (-6.63 mm Hg [95% CI, -8.43 to -4.82] vs -2.70 mm Hg [95% CI, -4.59 to -0.81]) and diastolic (-5.12 mm Hg [95% CI, -6.48 to -3.75] vs -2.01 mm Hg [95% CI, -3.47 to -0.54]) blood pressure. The effect on diastolic blood pressure was significantly larger in populations taking antihypertensive drugs than in untreated populations (-5.31 mm Hg [95% CI, -6.64 to -3.99] vs -2.91 mm Hg [95% CI, -3.66 to -2.16]). This meta-analysis clearly shows that weight loss is important for the prevention and treatment of hypertension

Improving the dietary quality of food parcels leads to improved dietary intake in Dutch food bank recipients-effects of a randomized controlled trial

Purpose: Since food banks have a strong influence on recipients’ diets, and seem to have difficulties in supporting healthy diets, improving the dietary quality of food parcels is important. The aim of our study was to assess whether improving the dietary quality of food parcels, using different strategies, can positively impact the actual dietary intake of Dutch food bank recipients. Methods: This randomized cross-over controlled trial (Trial ID: ISRCTN40554133) with four intervention conditions [(1) Control (standard food parcel), (2) snacks– (standard food parcel with replacement of unhealthy snacks by staple foods), (3) FV+ (standard food parcel plus the recommended daily amount of fruit and vegetables), (4) snacks– + FV+ (standard food parcel with replacement of unhealthy snacks by staple foods plus the recommended daily amount of fruit and vegetables)] included 163 food bank recipients, from three food banks. At baseline, participants filled in a questionnaire. Dietary intake data were collected through 24-h recalls after both intervention conditions at 4 and 8 weeks follow-up. Primary outcome was daily fruit and vegetable intake, secondary outcomes were daily dietary intakes of food groups and nutrients. Results: Multi-level linear regression analysis, using a two-level model, showed a higher mean daily fruit intake in participants in the FV+ condition than in participants in the Control condition (delta (δ): 74 [40.3;107.6] g). Both mean daily fruit and vegetable intake were higher in participants in the Snacks– + FV+ condition than in participants in the Control condition (fruit δ: 81.3 [56.5;106.2] g; vegetables δ: 46.2 [17.5;74.9] g), as well as in the Snacks– condition (fruit δ: 70.0 [38.8;101.1] g; vegetables δ: 62.2 [26.2; 98.2] g). Conclusions: This study shows that improving the dietary quality of food parcels can positively impact the dietary intake of Dutch food bank recipients. With this information we can further develop effective strategies that can be easily applied by food banks, to improve dietary intake of food bank recipients

The prevalence of overweight and obesity and its determinants in children with and without disabilities

OBJECTIVES: To compare the prevalence of overweight and obesity and nutrition and physical activity behavior between primary school children with and without disabilities. STUDY DESIGN: Body weight and height were measured in 4072 children from regular primary schools in the city of Zwolle, the Netherlands, and in 85 children from a school for children with disabilities. Furthermore, parents completed a questionnaire on the child's nutrition and physical activity behavior. A χ(2) analysis was used to test categorical variables between groups, and analysis of variance was used for continuous variables. RESULTS: The prevalence of overweight and obesity among disabled children was 30.6% and 10.6%, respectively, which is three and six times higher than in nondisabled children (P < .001). Furthermore, our study shows statistically significant differences in nutrition and physical activity behavior between disabled and nondisabled children. CONCLUSIONS: There is a need to promote a healthy lifestyle and to reduce the prevalence of overweight and obesity in disabled children

Socio-economic differences in the change of fruit and vegetable intakes among Dutch adults between 2004 and 2011: The GLOBE study

Objective To investigate socio-economic differences in changes in fruit and vegetable intake between 2004 and 2011 and explore the mediating role of financial barriers in this change.Design Respondents completed a self-reported questionnaire in 2004 and 2011, including questions on fruit and vegetable intake (frequency per week), indicators of socio-economic position (education, income) and perceived financial barriers (fruits/vegetables are expensive, financial distress). Associations were analysed using ordinal logistic regression. The mediating role of financial barriers in the association between socio-economic position and change in fruit and vegetable intake was studied with the Baron and Kenny approach.Setting Longitudinal GLOBE study.Subjects A total of 2978 Dutch adults aged 25-75 years.Results Respondents with the lowest income in 2004 were more likely to report a decrease in intake of cooked vegetables (P-trend<0·001) and raw vegetables (P-trend<0·001) between 2004 and 2011, compared with those with the highest income level. Respondents with the lowest education level in 2004 were more likely to report a decrease in intake of fruits (P-trend=0·021), cooked vegetables (P-trend=0·033), raw vegetables (P-trend<0·001) and fruit juice (P-trend=0·027) between 2004 and 2011, compared with those with the highest education level. Financial barriers partially mediated the association between income and education and the decrease in fruit and cooked vegetable intake between 2004 and 2011.Conclusions These results show a widening of relative income and educational differences in fruit and vegetable intake between 2004 and 2011. Financial barriers explained a small part of this widening

Exploring food insecurity and obesity in Dutch disadvantaged neighborhoods:A cross-sectional mediation analysis

Background: Food insecurity is related to risk of adverse health outcomes such as obesity, but the explanatory factors underlying this association are still unclear. This study aimed to assess the association between food insecurity and obesity, and to explore potential mediation by sociodemographic and lifestyle factors. Methods: This cross-sectional study was conducted among 250 participants in a deprived urban area in the Netherlands. Data on sociodemographic and lifestyle factors, food insecurity status and diet quality were collected using questionnaires. Diet quality was determined based on current national dietary guidelines. BMI was calculated from self-reported height and weight. Regression analyses were performed to explore the association between food insecurity and BMI status. Mediation analyses were performed to estimate the total-, direct-, and indirect effect and proportion of total effect mediated of the food insecurity-obesity association. Results: The overall prevalence of food insecurity was 26%. Food insecurity was associated with obesity (OR = 2.49, 95%CI = 1.16, 5.33), but not with overweight (OR = 1.15, 95%CI = 0.54, 2.45) in the unadjusted model. The food insecurity-obesity association was partially mediated by living situation (proportion mediated: 15.4%), diet quality (- 18.6%), and smoking status (- 15.8%) after adjustment for other covariates. Conclusions: The findings of this study suggest an association between food insecurity and obesity. Living situation, diet quality and smoking status explained part, but not all, of the total association between food insecurity and obesity. Future longitudinal studies are warranted to examine the temporal order of the food insecurity-obesity association and potential mediators in this relationship. In addition, food insecurity and its potential consequences need to be taken into account in obesity prevention programs and policies
