Predictors of college-student food security and fruit and vegetable intake differ by housing type

ABSTRACT

Objective: We assessed whether college-student characteristics associate with food security and fruit and vegetable (FV) intake and whether these associations differ in students in housing with and without food provision. Participants: 514 randomly-sampled students from a large, Midwestern, public university in 2012 and 2013 Methods: Ordered logistic regression tested how student characteristics associate with food security. Linear regression tested how student characteristics associate with FV intake. Analyses were stratified by housing type – that is, housing with food provision (dormitory, fraternity/sorority house, cooperative) vs. housing without food provision.Results: Only among those living in housing without food provision, males (p = 0.04), students without car access (p = 0.005), and those with marginal (p = 0.001) or low (p = 0.001) food security demonstrated lower FV intake. Conclusions: Housing with food provision may buffer the effects of student characteristics on food.     

德国食品卫生法律制度刍议

德国作为世界四大食品出口国之一,食品出口额在欧洲一直稳居榜首.其最主要的原因要归于业界对德国食品质量有口皆碑的赞誉,隐匿其后的则是德国健全的食品卫生法律制度居功厥伟的作用.无论是其食品卫生法律制度体系架构的严密性,还是具体操作层面的诸多实施方式都颇具借鉴意义.

危害食品安全刑事案件具体法律应用问题研究

食品安全事故频发，保障食品安全已引起社会广泛关注。刑法作为保障食品安全的最后一道屏障，由于其对危害食品安全犯罪的定性不当、保护范围较窄、保护滞后等问题，有大量危害食品安全犯罪案件未进入司法程序，凸显了刑法在惩处食品安全犯罪行为过程中的乏力，也在一定程度上纵容了危害食品安全的犯罪行为。应借鉴美国立法，完善我国危害食品安全犯罪刑事立法，形成严密的刑事立法体系，克服危害食品安全犯罪在刑法规制上的不足。     

国际慢城运动及其对我国城市建设的启示

在全球化的时代背景下,兴起于意大利的慢食和慢城运动,已经成为对抗速食文化尤其是文化趋同化的一种体现。近年来,国内学者更是将慢城理念引入我国城市建设、小城镇建设中,因此有关慢城运动的内涵以及慢城对于全球化问题的思考就显得尤为重要。将意大利慢食、慢城运动的兴起置于全球化背景中,探讨慢城运动的缘起、内涵、特质等,使之给我国城市建设带来一些思考和启发。     

Combining Food Frequency and Survey Data to Quantify Long-Term Dietary Exposure: A Methyl Mercury Case Study

Twenty-four-hour recall data from the Continuing Survey of Food Intake by Individuals (CSFII) are frequently used to estimate dietary exposure for risk assessment. Food frequency questionnaires are traditional instruments of epidemiological research; however, their application in dietary exposure and risk assessment has been limited. This article presents a probabilistic method of bridging the National Health and Nutrition Examination Survey (NHANES) food frequency and the CSFII data to estimate longitudinal (usual) intake, using a case study of seafood mercury exposures for two population subgroups (females 16 to 49 years and children 1 to 5 years). Two hundred forty-nine CSFII food codes were mapped into 28 NHANES fish/shellfish categories. FDA and state/local seafood mercury data were used. A uniform distribution with minimum and maximum blood-diet ratios of 0.66 to 1.07 was assumed. A probabilistic assessment was conducted to estimate distributions of individual 30-day average daily fish/shellfish intakes, methyl mercury exposure, and blood levels. The upper percentile estimates of fish and shellfish intakes based on the 30-day daily averages were lower than those based on two- and three-day daily averages. These results support previous findings that distributions of "usual" intakes based on a small number of consumption days provide overestimates in the upper percentiles. About 10% of the females (16 to 49 years) and children (1 to 5 years) may be exposed to mercury levels above the EPA's RfD. The predicted 75th and 90th percentile blood mercury levels for the females in the 16-to-49-year group were similar to those reported by NHANES. The predicted 90th percentile blood mercury levels for children in the 1-to-5-year subgroup was similar to NHANES and the 75th percentile estimates were slightly above the NHANES.

An Empirical Test of Competing Theories of Hazard-Related Trust: The Case of GM Food

Few scholars doubt the importance of trust in explaining variation in public perception of technological risk. Relatively little, however, is known about the particular types of judgments that people use in granting or withholding trust. This article presents findings from an empirical study that explores several dimensions of trust relevant for citizens' judgments of scientists involved in the development of GM food. The relationship between particular dimensions of trust and perceptions of GM food risk is also explored, using structural equation modeling. Results suggest that trust judgments based on the perception of shared values are most important in relation to GM food risk, but that judgments about scientists' technical competence are also important.     

Steps in the Right Direction,Against the Odds,An Evaluation of a Community‐Based Programme Aiming to Reduce Inactivity and Improve Health and Morale in Overweight and Obese School‐Age Children

The study describes an evaluation of a 48‐week physical activity and nutritional education programme for overweight/obese school‐age children using quantitative and qualitative methods. The majority of participants were obese or severely obese when enrolled, and while some improvements in body mass index, self‐esteem and engagement in a range of physical activities were noted, difficulties in evaluating a complex community‐based intervention were highlighted. Children, parents and health professionals described a range of benefits from attending the programme but more intensive services are likely to be needed for the most seriously obese children and for those families resisting intervention.
