Prevalence of Food Insecurity and Associations with Academic Performance, Food Consumption and Social Support among University Students during the COVID-19 Pandemic: FINESCOP Project in Iceland.

(1) Background: Food insecurity (FI) among university students has received less attention in Europe than in other regions before and during the COVID-19 pandemic. (2) Methods: A cross-sectional study was conducted between January and March 2022 using an online questionnaire (n = 924). The questionnaire addressed food security status; demographic, socioeconomic, and educational variables; academic performance; food consumption; and social support networks. The validated Food Insecurity Experience Scale was used to measure food security. Binary logistic regressions adjusted by age and gender were applied to identify FI-related factors. (3) Results: Just over 17% of the students were living with some level of FI, nearly one in three students reported having consumed few kinds of food, and 3.9% spent an entire day without eating due to a lack of resources. Food insecurity was associated with a higher likelihood of negative academic performance, decreased food consumption, and a lower likelihood of having a large support network, when compared to food-secure respondents. (4) Conclusions: The findings suggest that FI negatively impacts students' academic performance and food consumption. Future public health programs should be prioritized to prevent students from experiencing hunger due to financial or resource constraints.

Prevalence and predictors of food insecurity among university students - Results from the Justus Liebig University Giessen, Germany.

This study aimed to assess the prevalence and associated factors of food insecurity (FI) among university students in Germany during the COVID-19 pandemic. We conducted a cross-sectional study (n = 626) between November and December 2021 at the Justus Liebig University in Giessen, Germany, using an online questionnaire. The analysis of FI was based on the Food Insecurity Experience Scale (FIES) by the Food and Agriculture Organization (FAO). We statistically validated our data using the Rasch model. Moreover, demographic, socio-economic and educational variables were collected using a questionnaire developed by the Food Insecurity among European University Students during the COVID-19 Pandemic (FINESCOP) consortium. Overall, 27.5 % of the university students are food insecure. The proportion of university students experiencing moderate or severe food insecurity (FImod+sev) is 10.4 % and the proportion experiencing severe food insecurity (FIsev) 0.9 %. Results from a logistic regression showed that students have a higher chance to be food insecure if they were not born in Europe and if their parents have a secondary or lower educational level. We further found an association between age and FI. Also receiving a student loan during the pandemic and getting food assistance increased the likelihood of being food insecure. Our results show that FI is prevalent among this particularly vulnerable population group. Thus, public health, as well as policy efforts may need to become more target group-specific in accordance with the identified circumstances and specific characteristics to avoid that university students suffer from FI.

Language delay and poorer school performance in children of mothers with inadequate iodine intake in pregnancy: results from follow-up at 8 years in the Norwegian Mother and Child Cohort Study.

PURPOSE: Some studies indicate that mild-to-moderate iodine deficiency in pregnant women might negatively affect offspring neurocognitive development, including previous results from the Norwegian Mother and Child Cohort study (MoBa) exploring maternally reported child development at age 3 years. The aim of this follow-up study was to investigate whether maternal iodine intake in pregnancy is associated with language and learning at 8 years of age. METHODS: The study sample includes 39,471 mother-child pairs participating in MoBa with available information from a validated food frequency questionnaire covering the first half of pregnancy and a questionnaire on child neurocognitive development at 8 years. Multivariable regression was used to explore associations of iodine intake from food and supplements with maternally reported child outcomes. RESULTS: Maternal iodine intake from food less than ~ 150 µg/day was associated with poorer child language skills (p-overall = 0.013), reading skills (p-overall = 0.019), and writing skills (p-overall = 0.004) as well as poorer school test result in reading (p < 0.001), and increased likelihood of the child receiving special educational services (p-overall = 0.042) (in non-iodine supplement users). Although significant, differences were generally small. Maternal use of iodine supplements in pregnancy was not significantly associated with any of the outcomes. CONCLUSIONS: Low habitual iodine intake in pregnant women, i.e., lower than the recommended intake for non-pregnant women, was associated with mothers reporting poorer child language, school performance, and increased likelihood of special educational services. We found no indications of benefits or harm of using iodine-containing supplements in pregnancy. Initiating use in pregnancy might be too late.

Suboptimal Maternal Iodine Intake Is Associated with Impaired Child Neurodevelopment at 3 Years of Age in the Norwegian Mother and Child Cohort Study.

Background: Severe iodine deficiency in pregnancy has major effects on child neurodevelopment, but less is known about the potential consequences of mild-to-moderate deficiency and iodine supplement use.Objective: We explored the associations between maternal iodine intake and child neurodevelopment at 3 y of age and the potential impact of maternal intake of iodine from supplements on the same outcomes.Methods: This population-based prospective observational study included 48,297 mother-child pairs recruited during pregnancy from 2002 to 2008. Maternal iodine intake was calculated based on a validated food-frequency questionnaire answered during midpregnancy that covered mean intake since the beginning of pregnancy. Associations between iodine intake and maternal-reported child language and motor development and behavior problems were explored by multivariable regression analyses.Results: In 33,047 mother-child pairs, excluding iodine supplement users, maternal iodine intake was associated with child language delay (P = 0.024), externalizing and internalizing behavior problems (both P < 0.001), and fine motor skills (P = 0.002) but not gross motor skills or the risk of not walking unaided at 17 mo of age. In 74% of the participants who had an iodine intake <160 µg/d (Estimated Average Requirement), suboptimal iodine intake was estimated to account for ∼5% (95% CI: -5%, 14%) of the cases of language delay, 16% (95% CI: 0%, 21%) of the cases of externalizing behavior problems >1.5 SD, and 16% (95% CI: 10%, 21%) of the cases of internalizing behavior problems >1.5 SD. In 48,297 mother-child pairs, including iodine supplement users, we found no protective effects of supplemental iodine during pregnancy on neurodevelopment.Conclusions: Maternal iodine intake below the Estimated Average Requirement during pregnancy was associated with symptoms of child language delay, behavior problems, and reduced fine motor skills at 3 y of age. The results showed no evidence of a protective effect of iodine supplementation during pregnancy.

Development of a nutrition knowledge questionnaire for obese adults.

BACKGROUND AND OBJECTIVE: The aim of this study was to develop a questionnaire for assessing nutritional knowledge among overweight adults. The questionnaire should reveal knowledge about current dietary recommendations, sources of nutrients, everyday food choices, and conditions related to overweight. DESIGN: The first draft of the nutrition knowledge questionnaire (113 items) was based on literature review. To ensure content validity and expert-assessed face validity, an expert panel examined the questionnaire. Thereafter, the questionnaire was tested for user friendliness and ambiguity by five students. The questionnaire was pilot tested in a group of obese adults, similar to the target group. The results were analyzed for item difficulty and internal consistency and comments made by respondents were taken into account. Two student groups, differing in nutritional expertise, answered the questionnaire on two occasions to test construct validity and test-retest reliability. After the retest, a total overview of the questionnaire was made by the expert panel. The final questionnaire consisted of 91 items. SUBJECTS: The pilot study was conducted in obese adults waiting for a gastric bypass operation (n=33). Construct validity (n=34) and test-retest reliability (n=27) was tested in two student groups: public health nutrition students and construction students. RESULTS: Results from the pilot study showed that internal consistency of the three first sections together was 0.84, measured by Cronbach's α. Test of construct validity showed that public health nutrition students scored significantly better than construction students (p<0.001 for all sections), and test-retest reliability for all sections together was 0.82 (Pearson's r). CONCLUSION: The knowledge questionnaire had reasonable content-, face-, and construct validities and overall good reliability. The questionnaire can be a useful tool for measuring nutrition knowledge among obese adults.

Data quality and practical challenges of thyroid volume assessment by ultrasound under field conditions - observer errors may affect prevalence estimates of goitre.

BACKGROUND: The ultrasonographic estimation of thyroid size has been advocated as being more precise than palpation to diagnose goitre. However, ultrasound also requires technical proficiency. This study was conducted among Saharawi refugees, where goitre is highly prevalent. The objectives were to assess the overall data quality of ultrasound measurements of thyroid volume (Tvol), including the intra- and inter-observer agreement, under field conditions, and to describe some of the practical challenges encountered. METHODS: In 2007 a cross-sectional study of 419 children (6-14 years old) and 405 women (15-45 years old) was performed on a population of Saharawi refugees with prevalent goitre, who reside in the Algerian desert. Tvol was measured by two trained fieldworkers using portable ultrasound equipment (examiner 1 measured 406 individuals, and examiner 2, 418 individuals). Intra- and inter-observer agreement was estimated in 12 children selected from the study population but not part of the main study. In the main study, an observer error was found in one examiner whose ultrasound images were corrected by linear regression after printing and remeasuring a sample of 272 images. RESULTS: The intra-observer agreement in Tvol was higher in examiner 1, with an intraclass correlation coefficient (ICC) of 0.97 (95% CI: 0.91, 0.99) compared to 0.86 (95% CI: 0.60, 0.96) in examiner 2. The ICC for inter-observer agreement in Tvol was 0.38 (95% CI: -0.20, 0.77). Linear regression coefficients indicated a significant scaling bias in the original measurements of the AP and ML diameter and a systematic underestimation of Tvol (a product of AP, ML, CC and a constant). The agreement between re-measured and original Tvol measured by ICC (95% CI) was 0.76 (0.71, 0.81). The agreement between re-measured and corrected Tvol measured by ICC (95% CI) was 0.97 (0.96, 0.97). CONCLUSIONS: An important challenge when using ultrasound to assess thyroid volume under field conditions is to recruit and train qualified personnel to perform the measurements. Methodological studies are important to assess data quality and can facilitate statistical corrections and improved estimates.

A survey among potential employers for developing a curriculum in public health nutrition.

OBJECTIVES: To describe which functions potential employers of public health nutritionists in Norway find important for a person trained in public health nutrition to be able to carry out. Further, to illustrate how the findings were used in the development of a curriculum for a bachelor in public health nutrition at Akershus University College. DESIGN: A non-random, cross-sectional survey using a questionnaire with both pre-coded and open-ended questions. SUBJECTS: Ninety-one establishments working in various fields more or less related to nutrition responded (response rate of 45 %). RESULTS: Local offices of the Norwegian Food Safety Authority were over-represented among respondents. Functions related to communication and food and nutrition laws and regulations were most frequently rated as important by the respondents. Functions in nutrition research, project work and policy and planning were also regarded important by more than half of the respondents. The priorities of the potential employers together with the additional comments and suggestions were taken into account when a new curriculum on public health nutrition was developed. CONCLUSIONS: The assessment of functions prioritized by employers of public health nutritionists gave a valuable input for developing a new curriculum in public health nutrition. It reflected the challenges of the real world that public health nutritionists will work in and therefore helped making the curriculum potentially more relevant.

Women's iodine status and its determinants in an iodine-deficient area in the Kayes region, Mali.

OBJECTIVE: To assess iodine status and its determinants in women of childbearing age in a rural area in the Kayes region, Mali, West Africa. DESIGN: Cross-sectional study where women's iodine status was indicated by urinary iodine concentration (UIC) and level of goitre based on palpation. Salt iodine was assessed semi-quantitatively at household level. Individual characteristics were collected using questionnaires. SETTING: Fifteen villages in a rural area in the Kayes region of Mali. SUBJECTS: Women aged 15-45 years (n=423). RESULTS: Median UIC was 2.7 microg dl(-1), and only 6% of the women had adequate iodine status of UIC >10 microg dl(-1). Most women (60%) had visible goitre, and only 9% were classified as without goitre. Only 39% of the households were using salt with any iodine, and level of knowledge about salt iodisation was low. Main determinants of UIC were breast-feeding and level of salt iodisation; currently breast-feeding women had lower UIC, and UIC increased with increasing level of iodine in household salt. Prevalence of goitre was lower in older women with higher body mass index. CONCLUSION: The study indicates severe iodine deficiency in the study area. Urgent action is needed to improve the situation through enforcing salt iodisation legislation and increasing the level of knowledge about the importance of iodised salt in the population.

Validation of the second version of a quantitative food-frequency questionnaire for use in Western Mali.

OBJECTIVE: To assess the relative validity of the second version of a quantitative food-frequency questionnaire (QFFQ), designed to measure the habitual food and nutrient intake in one season in rural populations in Western Mali, West Africa. DESIGN: The dietary intake during the previous week was assessed with the 164-item QFFQ administered by interview. This was compared with the intake from a 2-day weighed record (WR) with weighed recipes. SETTING: The village of Ouassala in the Kayes region, Western Mali. SUBJECTS: Thirty-four women and 36 men aged 15-45 years, from 29 households. RESULTS: The QFFQ gave a lower intake of lunch and dinner and a higher intake of snacks than the WR. The discrepancies were larger for women than for men. The median proportion of subjects classified in the same quartile of intake was 29% for food groups and 36% for energy and nutrients. For classification into extreme opposite quartiles, the median proportion was 6% for food groups and 7% for energy and nutrients. Spearman's rank correlation for energy and nutrients ranged from 0.16 (% energy from protein) to 0.62 (retinol equivalents). CONCLUSIONS: The second version of the QFFQ tends to underestimate total food weight. The methods used for estimating food portion size should therefore be applied with caution. The changes made from the first version had little effect. The ability to rank subjects according to dietary intake is similar with both versions. The improved layout of the new QFFQ makes it a more user-friendly tool for comparing dietary intake between population groups and for measuring changes over time.
