ABSTRACT

BACKGROUND: Malnutrition linked to noncommunicable diseases presents major health problems across Europe. The World Health Organisation encourages countries to conduct national dietary surveys to obtain data to inform public health policies designed to prevent noncommunicable diseases. METHODS: Data on 27334 participants aged 19-64y were harmonised and pooled across national dietary survey datasets from 12 countries across the WHO European Region. Weighted mean nutrient intakes were age-standardised using the Eurostat 2013 European Standard Population. Associations between country-level Gross Domestic Product (GDP) and key nutrients and nutrient densities were investigated using linear regression. The potential mitigating influence of participant-level educational status was explored. FINDINGS: Higher GDP was positively associated with total sugar intake (5·0% energy for each 10% increase in GDP, 95% CI 0·6, 9·3). Scandinavian countries had the highest vitamin D intakes. Participants with higher educational status had better nutritional intakes, particularly within lower GDP countries. A 10% higher GDP was associated with lower total fat intakes (-0·2% energy, 95% CI -0·3, -0·1) and higher daily total folate intakes (14µg, 95% CI 12, 16) in higher educated individuals. INTERPRETATION: Lower income countries and lower education groups had poorer diet, particularly for micronutrients. We demonstrate for the first time that higher educational status appeared to have a mitigating effect on poorer diet in lower income countries. It illustrates the feasibility and value of harmonising national dietary survey data to inform European policy regarding access to healthy diets, particularly in disadvantaged groups. It specifically highlights the need for strong policies supporting nutritional intakes, prioritising lower education groups and lower income countries.

ABSTRACT

Mineral ballasting enhances carbon export from the surface to the deep ocean; however, little is known about the role of this process in the ice-covered Arctic Ocean. Here, we propose gypsum ballasting as a new mechanism that likely facilitated enhanced vertical carbon export from an under-ice phytoplankton bloom dominated by the haptophyte Phaeocystis. In the spring 2015 abundant gypsum crystals embedded in Phaeocystis aggregates were collected throughout the water column and on the sea floor at a depth below 2 km. Model predictions supported by isotopic signatures indicate that 2.7 g m-2 gypsum crystals were formed in sea ice at temperatures below -6.5 °C and released into the water column during sea ice melting. Our finding indicates that sea ice derived (cryogenic) gypsum is stable enough to survive export to the deep ocean and serves as an effective ballast mineral. Our findings also suggest a potentially important and previously unknown role of Phaeocystis in deep carbon export due to cryogenic gypsum ballasting. The rapidly changing Arctic sea ice regime might favour this gypsum gravity chute with potential consequences for carbon export and food partitioning between pelagic and benthic ecosystems.

ABSTRACT

BACKGROUND/OBJECTIVES: To identify and describe dietary patterns in Danish adults and to examine which demographic and health-related lifestyle factors are associated with dietary patterns. SUBJECTS/METHODS: Data derived from the Danish national survey of diet and physical activity collected in 2003-2008 and included 1569 men and 1785 women. Diet was assessed by a 7-day pre-coded food diary. Information on age, gender, weight, height, physical activity, smoking habits, educational level and attitudes towards healthy eating habits was derived from face-to-face interviews. Principal component analysis was applied to explore dietary patterns. Associations with lifestyle factors were examined by means of multiple regression analyses. RESULTS: Three major dietary patterns were identified: a 'traditional' pattern correlated with intake of rye bread, white bread, fat on bread, cheese, jam, cold meat, minced meat, potatoes and gravy, and cake and biscuits; a 'health-conscious' pattern correlated with coarse bread, fruit, vegetables, low-fat dairy, nuts, water and tea; and a 'fast food' pattern correlated with pizza, hamburger/spring rolls, crisps, rice and pasta, sugar-sweetened soft drinks and sweets. The 'traditional' pattern was positively associated with male gender and age, whereas the 'health-conscious' pattern was positively associated with being female, increasing age and educational level. The 'fast food' pattern was inversely associated with age and smoking. CONCLUSIONS: Three distinct dietary patterns were identified, and associated lifestyle and demographic factors were characterised. The findings are valuable in targeting future nutrition education and will enable more focused strategies in communicating food-based dietary guidelines.

ABSTRACT

AIMS: The aim of this study was to examine the association between different dimensions of socioeconomic position, body mass index (BMI) and obesity in the Danish population. Possible interactions between the different dimensions and gender differences were also investigated. METHODS: This was a cross-sectional survey conducted in 2000-2002 including a simple random sample from the civil registration system, comprising 1953 males and 2167 females aged 4-75 years. Information about different dimensions of socioeconomic position, height and weight was obtained by face-to-face interview. Associations between dimensions of socioeconomic position and weight status were examined by use of linear multiple regression analysis and logistic regression analysis. RESULTS: BMI and prevalence of obesity were significantly associated with education for both men and women. Odds ratios (ORs) for obesity were 2.9 (95% confidence interval (CI) 1.4-5.9) and 6.5 (95% CI 2.3-18.7) for those with basic school as compared with those with long higher education for men and women, respectively. Women outside the labour market had higher BMIs and a greater prevalence of obesity (OR 2.5 (95% CI 1.6-3.9)) after adjustment for educational level. CONCLUSIONS: Education was the dimension most consistently associated with BMI and obesity, indicating the importance of cultural capital for weight status. The gender-specific pattern showed a stronger social gradient for women, and indicated that a high relative body weight was associated with less favourable social and material conditions for women, but not for men. A public health strategy to prevent and reduce obesity should be gender-specific, focus on groups with short education, and incorporate cultural norms.

ABSTRACT

BACKGROUND: Danish adolescents have poor dietary habits compared to current recommendations. The present study aimed to develop a recommended food intake pattern for adolescents consistent with Danish Dietary Guidelines (DDG), Nordic Nutrition Recommendations (NNR) and dietary preferences. METHODS: The nutrient content of a food intake pattern consistent with DDG was calculated using dietary intake data from a random sample of 11-15-year-old boys (n = 85) and girls (n = 70). A recommended food intake pattern was modelled to meet NNR. The discretionary energy allowance was calculated as the difference between the total energy level and the energy needed to meet recommended nutrient needs. The flexibility of the recommended food intake pattern was tested against various energy requirements and with the inclusion of basic foods with higher sugar and/or fat content. RESULTS: The developed food intake pattern meets all nutrient goals except for vitamin D. At low energy requirements, the intake of iron and selenium is of concern. To fulfil nutrient recommendations, half of the bread/cereals and vegetables consumed should be fibre-rich, and fats should be of plant origin. CONCLUSIONS: The recommended food intake pattern meets most nutrient recommendations and makes it possible to advise on discretionary energy.

ABSTRACT

A total of 570 lyophilised Brassica root and shoot tissue samples were hydrolyzed, and the liberated isothiocyanates (ITCs) were analyzed by gas chromatography-flame photometric detection (GC-FPD). Glucosinolates (GSLs) were extracted from samples of the same tissues and analyzed by high-performance liquid chromatography (HPLC). The concentrations of six GSLs/ITCs (2-propenyl, 3-butyl, 4-pentenyl, benzyl, 4-methylthiobutyl, and 2-phenylethyl) as determined by the two techniques were compared. In 79% of the samples, the concentration of GSLs in the tissues was greater than that of the ITCs released on hydrolysis. Several possible reasons for the difference are proposed, including the effect of tissue storage time, hydrolysis of GSLs may be less efficient than the GSL extraction procedure, or some of the ITCs formed reacted with plant proteins and amino acids in the sample and were therefore not detected in the extract. GSL concentration in plant tissues is used to estimate the biofumigation potential of the plant tissue, whereas the actual biofumigation effect is thought to be due to the ITCs formed by hydrolysis of the plant-based GSLs. The variation between ITC and GSL values therefore has implications for the assessment of the biofumigation potential of the plant tissue.

ABSTRACT

MATERIAL AND METHODS: Trends in the prevalence of overweight and obesity in Denmark were compared to changes in diet and physical activity by using data from the nationwide dietary surveys of 1985 and 1995 comprising 2,000 adults, aged 15-80 years. RESULTS: The prevalence of overweight and obesity has increased by more than 20% in men (1985: 35.7% vs 1995: 44.1%) and women (1985: 22.3% vs 1995: 29.4%). The prevalence of obesity rose especially in men from 1985 (5.0%) to 1995 (8.8%), less dramatically in women (1985: 5.3% vs 1995: 6.6%). A decrease of 20% and 5% in energy intake has been registered, respectively in men and women. At the same time, sedentary work increased considerably from 1995 (19.5%) to 1985 (38.2%), whereas leisure time physical activity was higher than before. DISCUSSION: The increasing prevalence of overweight and obesity is probably explained by a decrease in the total energy expenditure, owing to the fact that sedentary work has doubled. Hence, a rise in the level of leisure time physical activity did not compensate for the lower expenditure of energy during working hours.

ABSTRACT

First instars of the soil-inhabiting whitefringed weevil, Naupactus leucoloma (Boheman), are a particularly good bioassay model for assessing volatile soil fumigants and biofumigants. Eggs are readily obtained and can be stored for long periods with larvae hatched on demand and the first instar is non-feeding, surviving without food or shelter. Longevity varies with temperature, but readily accommodates the period required to conduct bioassays without appreciable mortality of untreated controls. In vitro bioassays of pure methyl isothiocyanate, the active ingredient from metham sodium soil fumigant, and the less volatile 2-phenylethyl isothiocyanate, sensitively detected differences in toxicity and effects of temperature. Bioassay of volatiles emitted from hydrolysed tissue of various isothiocyanate-producing Brassica plants revealed widely varying toxicity effects, indicating that bioassays with N. leucoloma are a sensitive and relevant indicator of the potential of different plants for biofumigation of soil-borne pest organisms.
