Number of meals eaten in relation to weight status among Norwegian adolescents.
2010
Aim: To assess the relationship between number of meals eaten and weight status, and to assess potential confounders of this relationship. Methods: A total of 2870 (participation rate: 85%) 9th and 10th graders (mean age: 15.5 years) at 33 schools completed questionnaires in May 2005. Number of meals was measured with questions asking whether they ate breakfast, lunch, dinner, and supper the day before, giving a scale ranging from zero to four meals/day. Data on gender, height, weight, education plans, intake of fruits and vegetables, consumption of unhealthy snacks, TV/computer time, physical activity level, and dieting were also collected. Results: The proportions of overweight adolescen…
Introduction of a school fruit program is associated with reduced frequency of consumption of unhealthy snacks.
2012
Background: A diet high in fruit and vegetables (FV) is inversely related to chronic diseases, and some studies suggest that increasing the intake of FV reduces the intake of unhealthy snacks. Objectives: The objectives were to analyze changes in the frequency of consumption of unhealthy snacks (soda, candy, and potato chips) from 2001 to 2008 in Norwegian children, to assess whether being part of a school fruit program reduces the frequency of unhealthy snack consumption, and to explore differences in sex and socioeconomic status. Design: Within the project Fruits and Vegetables Make the Marks, 1488 sixth- and seventh-grade pupils from 27 Norwegian elementary schools completed a questionna…
Eight-year trends in food, energy and macronutrient intake in a sample of elderly German subjects.
2005
Time trends in the food and the corresponding energy and macronutrient intake between 1994 and 2002 are investigated as part of the longitudinal study on nutrition and health status in an ageing population in Giessen, Germany (GISELA study). The dietary intake is assessed via a 3 d estimated dietary record especially developed and validated for this study. A total of 2135 records from 532 subjects, aged 60 years and over, are analysed separately according to sex and age groups (born 1904–1928 and born 1929–1942). Results show that the food, energy and macronutrient intake of the GISELA subjects stayed fairly stable over the study period. However, some significant changes in the consumption …
Consumption of vegetables at dinner in a cohort of Norwegian adolescents.
2007
Abstract This longitudinal study examined the frequency of consumption of vegetables for dinner by Norwegian adolescents and their parents. Associations of perceived availability, correlations and stability were explored. The longitudinal cohort consist of 1950 adolescents attending 6th/7th (2002) and 9th/10th (2005) grade, and their parents (n = 1647). Only 40% of the adolescents and 60% of the adults reported to have eaten vegetables for dinner yesterday, the reported frequency of vegetables for dinner were 3.7 and 4.1 times/week in 2002 and 2005, respectively, and 4.8 times/week for parents. Girls ate more than boys, and high SES adolescents ate more than low SES adolescents. There were …
Survey of the occurrence of Giardia duodenalis cysts and Cryptosporidium spp. oocysts in green leafy vegetables marketed in the city of Valencia (Spa…
2022
The role of vegetables usually consumed without prior culinary treatment is known to contribute to the prevalence of foodborne diseases. Cysts and oocysts can contaminate food, which can then be the source of infection in humans. The aim of the study was to assess the occurrence of Giardia duodenalis and Cryptosporidium spp. (oo) cysts in green leafy vegetables marketed in the city of Valencia (Spain) combining parasitological methods, two real-time qPCRs and light microscopy. An experimental field study was conducted on 129 vegetable samples, 64 from conventional farms and 65 from ecological (organic) farms. The samples were washed with water, and the resulting solution after removing the …
Fast simultaneous determination of prominent polyphenols in vegetables and fruits by reversed phase liquid chromatography using a fused-core column
2015
A reversed-phase high-performance liquid chromatography method with photodiode array detection has been developed enabling the joint determination of 17 prominent flavonoids and phenolic acids in vegetables and fruits. A multi-segmented gradient program using a fused-core column for the separation of several phenolic classes (phenolic acids and flavonoids) has been optimised. The influence of extraction conditions (sample freeze-drying, ultrasound extraction, solvent composition and extraction time) has been also optimised using response surface methodology with tomato samples as a model. Complete recoveries (76-108%) were obtained for the phenolic compounds present in tomato. The developed…
Development and validation in a group of industry workers, of an application for audiometric screening: A solution for social distance during COVID-1…
2020
In the context of the global COVID-19 pandemic, companies and institutions all over the world are trying to find the best ways to reorganize their activity, minimizing the contagion risk among their employees, so as to protect their health and prevent internal SARS-COV-2 outbreaks. The recent development of new communication technologies, such as smartphones and tablets, has paved the way for the development and implementation of different applications. Starting with the above issues, in this study, we wanted to investigate the efficacy of iAudiometry application developed by our research team for the detection of deficits in the auditory system. Furthermore, we analyzed the precision in de…
Aquatic pollution may favor the success of the invasive species A. franciscana
2015
The genus Artemia consists of several bisexual and parthenogenetic sibling species. One of them, A. franciscana, originally restricted to the New World, becomes invasive when introduced into ecosystems out of its natural range of distribution. Invasiveness is anthropically favored by the use of cryptobiotic eggs in the aquaculture and pet trade. The mechanisms of out-competition of the autochthonous Artemia by the invader are still poorly understood. Ecological fitness may play a pivotal role, but other underlying biotic and abiotic factors may contribute. Since the presence of toxicants in hypersaline aquatic ecosystems has been documented, our aim here is to study the potential role of an…
COLLARD GREEN (BRASSICA OLERACEA VAR. ACEPHALA) CULTIVATION IN SICILY
2013
Collard greens (Brassica oleracea var. acephala) are a group of plants cultivated for its thick, slightly bitter, edible leaves. As other Brassicaceae, have a good nutritional value as they are a good sources of vitamin C and soluble fiber, and contain various compounds with potent anticancer properties. In order to enhance collard cultivation in Sicily, different planting dates were tested. The research was carried out during 2009-2010 in the experimental field of SAgA Department – University of Palermo. Plants of a Sicilian local cultivar, with high vigor, good emission of side shoots, large and moderately curly leaves and long and strong petiole, were planted in three different periods: …
Curve Number: Empirical Evaluation and Comparison with Curve Number Handbook Tables in Sicily
2014
The curve number (CN) method is widely used for estimating direct runoff depth from rainstorms. The procedure is on the basis of the parameter CN, a lumped expression of basin absorption and runoff potential, and a second parameter, initial abstraction (IA), which represents the interception, infiltration, and surface depression during the early part of a storm. The evaluation of CN in Sicily at a basin scale from rainfall-runoff multiday events is done using rainfall-runoff observations during the period 1940–1997 (mean record length of 20 years) in 61 Sicilian watersheds using three different methods: (1) the national engineering handbook, section 4 hydrology (NEH4) method (NEH4M) (the me…
