Households' Food Insecurity and Its Association with Demographic and Socioeconomic Factors in Gaza Strip, Palestine: A Cross-Sectional Study.

Background: This sudy aimed to identify the prevalence of household's food insecurity and its association with demographic and socioeconomic factors. Methods: A cross-sectional study was conducted in September 2021 among a representative sample of households in the Gaza strip governorates. A total of 1167 households randomly selected from all five governorates and were included in the study. The Radimer/Cornell food security scale was used to determine the prevalence and levels of household food insecurity. The household's demographic and socioeconomic characteristics were obtained using an interview-based questionnaire. Statistical analysis was performed using SPSS version 25. Results: The overall prevalence of household's food insecurity was 71.5%. The prevalence by governorates was highest in Gaza (30.8%), followed by Khanyounis (23.0%), North-Gaza (18.6%), Middle-Area (15.2%) and Rafah (12.4%). Regarding the food insecurity levels, 333 (28.5%) of the households were food secure, 422 (36.2%) had mild food insecurity, 161 (13.8%) had moderate food insecurity, and 251 (21.5%) had severe food insecurity. Significant associations were found between governorates, monthly income, homeownership, work status with the household's food insecurity, (Crude OR [COR] = 2.02, 95% CI = [1.02-3.98], P value < 0.05), (COR = 2.00, 95% CI = [1.04-2.75], P value < 0.05), (COR = 2.36, 95% CI = [1.39-3.99], P value < 0.05), and (COR = 1.14, 95% CI = [0.66-1.97], P value < 0.05), respectively. Conclusions: Our study demonstrates that food insecurity is highly prevalent in the Gaza strip and is associated with poor living conditions. Therefore, this high prevalence should be seriously discussed and urgently considered.

Developing suitable methods of nutritional status assessment: a continuous challenge.

Reliable information about the nutritional status is essential to identify potential critical nutrients and the population groups at risk of deficiency, as well as to develop effective public health policies to counteract unfavorable nutrition patterns that contribute to morbidity and mortality. In this review, the important role of biomarkers in the assessment of nutritional status is outlined, major strengths and limitations of established and new biomarkers are described, and important criteria for biomarker selection and development are discussed. Indeed, biomarkers offer a more objective assessment tool than pure dietary approaches that suffer from inadequate data reporting in particular, although biomarkers are often only measured in subsamples because of the higher costs and proband burden they entail. However, biomarkers are subject to individual variability and influences from other factors besides the nutrient of interest. Rapid turnover or tight control of nutrient concentrations in blood (homeostasis) limits their sensitivity as biomarkers, as in the case of many trace elements. The existence of different forms of a micronutrient in the body adds additional complexity. Functional biomarkers, such as enzyme activities, mirror long-term status better but are subject to confounding factors, and some are influenced by several micronutrients, not specific for only 1, so using a combination of biomarkers is advisable. Additionally, the applicability of a biomarker also depends on the existence of adequate reference values and cutoff points for the target population. Therefore, a careful selection is warranted, especially when biomarkers are to be used in larger samples.

Fruit and vegetable intake in Austrian adults: intake frequency, serving sizes, reasons for and barriers to consumption, and potential for increasing consumption.

OBJECTIVE: To assess the intake frequency of fruit and vegetables, serving sizes, reasons for and barriers to consumption, and the potential for increasing fruit and vegetable intake. DESIGN: A nationwide postal questionnaire survey was conducted in 2006 over all four seasons. The participants were stratified according to occupation and sex. The response rate for 5130 questionnaires sent out was 52.7 %. SETTING: Austria. SUBJECTS: Austrian adults, aged 19-64 years. RESULTS: Daily fruit consumption was reported by 57.1 % of the participants and daily vegetable consumption by 36.2 %. On average, 2.1 (SD 1.9) servings (250 (SD 225) g) of fruit and 1.7 (SD 1.3) servings (198 (SD 159) g) of vegetables were consumed daily. Women ate fruit and vegetables both more frequently and in greater quantities than men. Both intake frequency and the number of fruit and vegetable servings were largely independent of seasonal fluctuations. The primary reason for the consumption of both fruit and vegetables was taste. The greatest barrier to higher intake was the perception that current individual consumption was already sufficient. Price did not constitute a relevant barrier in Austria. At present, the potential for increasing fruit and vegetable intake can be estimated at two servings. CONCLUSIONS: Austrian adults still consume less fruit and vegetables than recommended. Strategies to increase intake should pay more attention to the taste instead of the various health aspects.

Bioactive compounds: definition and assessment of activity.

Biomarkers and their role in evaluating efficacy and safety were the topic of the 23rd Hohenheim Consensus Meeting at the University of Hohenheim in Stuttgart. Scientists who had published and reviewed scientific and regulatory papers on the topic were invited, among them basic researchers, toxicologists, clinicians, and nutritionists. The participants were presented with 11 questions (in bold font), which were discussed and answered (in italic font) at the workshop, with the aim of summarizing the current state of knowledge on the subject. The explicatory text accompanying the short answers was produced and agreed on after the conference and was backed up by corresponding references.

Promoting fruit and vegetable consumption among European schoolchildren: rationale, conceptualization and design of the pro children project.

BACKGROUND/AIMS: The Pro Children Project was designed to assess fruit and vegetable consumption in European schoolchildren and their parents, as well as determinants of the children's consumption patterns. A second objective was to develop and test strategies, applicable across Europe, for promoting consumption of fruits and vegetables among schoolchildren and their parents. In this paper, the rationale, theoretical background, overall design and implementation of the project is presented. METHODS: Surveys of national, representative samples of 11-year-old schoolchildren and their parents were conducted in 9 countries, i.e. in Austria, Belgium, Denmark, Iceland, the Netherlands, Norway, Portugal, Spain and Sweden. Comprehensive school-based educational programmes have been developed and tested in three settings, i.e. in Spain, the Netherlands and in Norway. A precoded 24-hour recall form combined with a set of food frequency questions assessing regular intake were used to assess fruit and vegetable consumption. Determinants were assessed employing a comprehensive theoretical framework including personal, social and environmental factors related to fruit and vegetable consumption. The intervention programmes have been tested employing a group-randomized trial design where schools have been randomly allocated to an intervention arm and a delayed intervention arm. Surveys among all participating children and their parents were conducted prior to the initiation of the intervention, immediately after the end of the intervention and at the end of the subsequent school year. CONCLUSION: The project is expected to provide new information of great importance for improving our understanding of consumption patterns of fruits and vegetables and for guiding future efforts to promote increased consumption patterns across Europe.

Fruit and vegetable intake of mothers of 11-year-old children in nine European countries: The Pro Children Cross-sectional Survey.

OBJECTIVE: To describe and compare fruit and vegetable intakes of mothers of 11-year-old children across Europe. METHODS: Cross-sectional surveys were carried out in 9 European countries in October/November 2003. Self-administered questionnaires assessing fruit and vegetable consumption were used for data collection. The current paper presents dietary intake data obtained by a precoded 24-hour recall and a food frequency questionnaire. RESULTS: The consumption levels of fruit and vegetables (without fruit juice) were in line with World Health Organization recommendations of > or =400 g/day for only 27% of all participating mothers. Based on both instruments, the Pro Children results showed comparatively high average fruit intake levels in Portugal, Denmark and Sweden (211, 203 and 194 g/day) and the lowest intake in Iceland (97 g/day). High vegetable intake levels were found in Portugal and Belgium (169 and 150 g/day), the lowest in Spain (88 g/day). A south-north gradient could not be observed in the Pro Children study. CONCLUSION: Fruit and vegetable intakes are low in mothers of 11-year-olds across Europe. Especially vegetable consumption can be regarded as marginal in most of the studied European countries. A high percentage of mothers indicated to eat fruit and vegetables less than once a day. The results have shown that national and international interventions are necessary to promote fruit and especially vegetable consumption in the European population of mothers.

Personal, social and environmental factors regarding fruit and vegetable intake among schoolchildren in nine European countries.

BACKGROUND/AIMS: Children in Europe are consuming less fruit and vegetables than recommended. Knowledge about the potential determinants of fruit and vegetable intake is vital to understand discrepancies in intake and to guide interventions. The aim of the present study was to assess personal, social and environmental factors regarding fruit and vegetable intake among 11- to 12-year-old children in Europe. METHODS: A cross-sectional survey was undertaken, with nationally or regionally representative samples of in total 13,305 children (mean age 11.4 years) from nine European countries. Pupils in the classroom completed a self-administered questionnaire measuring fruit and vegetable intake and personal, social and environmental factors during one school lesson. Age-adjusted covariance analyses were carried out by gender, for the full sample and for each country separately. Proportions responding positively to the constructs are presented. RESULTS: Overall, European children held a positive attitude towards fruit and vegetable intake. For some constructs, large between-country differences were found. Children had a more positive attitude towards fruit than towards vegetables, and girls were on average more positive than boys. The children perceived their social environment as supportive towards fruit and vegetable intake. They reported good to very good availability of fruit and vegetables at home. However, availability at school and during leisure time activities seemed to be low, both for fruit and for vegetables. CONCLUSION: A large majority of the children reported positively to the personal and social factors regarding fruit and vegetable intake. As regards availability of fruit and vegetables at school and leisure time, and accessibility of fruit and vegetables at home, there is room for improvement.

Attitudes of Austrian adults to the consumption of fruits and vegetables.

BACKGROUND: Epidemiological studies confirm that high fruit and vegetable intake correlates with a reduced risk of cardiovascular disease, various kinds of cancer and other disease. Based on these results authorized bodies worldwide recommend to eat more fruits and vegetables, e.g., the 'five a day' campaign. SUBJECTS AND METHODS: Through 24-hour dietary recalls (studies 2000-02) the intake of 2,318 Austrian adults (19-65 years) were examined. 38.5% participants were male and 61.5% female. RESULTS: Austrian adults consume on average 248 +/- 316 g vegetables per day. The most popular vegetables are leafy, fruit and root vegetables. Pulses are seldom eaten. Women consume (252 +/- 184 g) slightly more vegetables than men (242 +/- 192 g). One fourth (26%) of the investigated subjects eat lower than 100 g vegetables, 21% consume amounts between 100 and 200 g and more than half (53%) eat more than 200g daily. Approximately half of the vegetable intake is consumed fresh and the other cooked, frozen vegetables are not often used by our study subjects. The daily intake of fruit is about 119 +/- 156 g. Men consume significantly lower quantities (107 +/- 159 g) of fruits than women (127 +/- 154 g) (p < 0.001). Half (51%) of the examined adults eat less than 100 g fruit per day, 23% between 100 and 200 g and only 26% more than the recommended 200 g. Most of the fruit is consumed fresh, frozen fruits and fruits in cans are not very popular. The favorite fruits are stone fruits, followed by citrus and berry fruits. Juice of fruits and vegetables was consumed in amounts of 56.7 +/- 151.3 ml/day. The daily intake of fruit and vegetable nectar is about 130.0 +/- 264.9 ml. If the amounts of juice and nectar are added to the average intake of fruit and vegetables, the whole quantity of fruit and vegetable intake is satisfying. CONCLUSION: Our survey shows that the investigated Austrian adults are not far away from reaching the minimum goal of 400 g fruit and vegetable intake per day. Nevertheless, 16% consumed less than 200 g vegetables and fruit. To improve health benefits, a higher intake of varied fruit and vegetables should be achieved.
