Exploring the nutritional vulnerability of homeless men in a Canadian urban setting

Abstract

Homelessness, Aboriginal ethnicity, and nutritional vulnerability are key determinants of health. Substance abuse further compounds health risk. This study explored the nutritional vulnerability of homeless men, some of who were solvent-users, to assess nutrition-related chronic disease risk factors. Anthropometric data were used to calculate disease risk using body mass index. Diet was assessed using a 24-hr food recall and data were compared to Canada’s Food Guide recommendations. A significant proportion of participants had low intakes of vegetables and fruit and milk and alternatives. More than half of the participants met the intake recommendations for grain servings and meat and alternatives. Solvent-using participants consumed significantly higher intakes of vegetables and fruit, grain products, and other foods and beverages, than non-solvent using men. More than half of the participants were classified as overweight or obese. Healthy food consumption was influenced by lack of stable housing, reliance on charitable food, and substance abuse.     

Minimizing Skin Color Differences Does Not Eliminate the Own-Race Recognition Advantage in Infants

An abundance of experience with own-race faces and limited to no experience with other-race faces has been associated with better recognition memory for own-race faces in infants, children, and adults. This study investigated the developmental origins of this other-race effect (ORE) by examining the role of a salient perceptual property of faces-that of skin color. Six- and 9-month-olds' recognition memory for own- and other-race faces was examined using infant-controlled habituation and visual-paired comparison at test. Infants were shown own- or other-race faces in color or with skin color cues minimized in grayscale images. Results for the color stimuli replicated previous findings that infants show an ORE in face recognition memory. Results for the grayscale stimuli showed that even when a salient perceptual cue to race, such as skin color information, is minimized, 6- to 9-month-olds, nonetheless, show an ORE in their face recognition memory. Infants' use of shape-based and configural cues for face recognition is discussed.     

Parents' retrospective reports of youth psychological responses to the sniper attacks in the Washington, DC, area

A random-digit-dial telephone survey was conducted in May 2003, with 355 parents of children ages 2-17 years old, living in Washington, DC, or in the two surrounding counties during the October 2002 sniper shootings, to examine parent retrospective reports of child event-related psychological distress. An estimated 32% of parents reported that children experienced at least one psychological distress symptom related to sniper shootings. Older children, females, children with a history of trauma exposure prior to sniper attacks, children whose parents reported routine disruption as the result of attacks, children whose parents perceived them as at great risk for harm from sniper attacks, and those children whose parents reported more traumatic stress symptoms in response to attacks were at greatest risk for reported psychological distress.     

Limits of Object Persistence: Young Infants Perceive Continuity of Vertical and Horizontal Trajectories,But Not 45‐Degree Oblique Trajectories

Previous research indicated that 4‐month‐old infants perceive continuity of objects moving on horizontal trajectories but appear to have difficulty processing occlusion events involving oblique trajectories. However, because perception of continuity of vertical trajectories has not been tested, it is uncertain whether this indicates a specific deficit for oblique trajectories or a specific advantage for horizontal trajectories. We evaluated the contribution of trajectory orientation and the form of occlusion in three experiments with one hundred and forty‐four 4‐month‐olds. Infants perceived continuity of horizontal and vertical trajectories under all conditions presented. However, they did not perceive continuity of an oblique (45°) trajectory under any condition. Thus, 4‐month‐olds appear unable to process continuity of a 45° trajectory. In a fourth experiment with forty‐eight 6‐ and 8‐month‐old infants, we demonstrated that by 6 months, infants' difficulty with oblique trajectories is overcome. We suggest that young infants' difficulty with markedly oblique trajectories likely relates to immature eye movement control.     

Dimensionality of thoughts of death and suicide: evidence from a study of homeless adolescents

This study used data from a sample of 444 homeless adolescents to determine whether thoughts of death and suicide form one construct (unidimensionality) or two distinct but correlated constructs (multi-dimensionality). Thoughts of death and suicide were common in the sample; over two-thirds of the adolescents positively endorsed at least one of the eight death- or suicide-related items. Evidence regarding dimensionality was mixed. Exploratory factor analysis results and similarity coefficients supported one construct; confirmatory factor analysis and external consistency results provided evidence for two constructs. The results were reconciled by considering suicidality as a continuum from thoughts of death to suicidal ideation, suicide attempts, and completed suicide.

Reforming Professional Training and Protecting Vulnerable Adults from Abuse: A Thematic Analysis of the New Social Work Degree's Prescribed Curriculum

E-mail: p.slater{at}mdx.ac.uk Summary This paper analyses the Prescribed Curriculum of the new Degreein Social Work in relation to the Department of Health themeof ‘protecting vulnerable adults from abuse’. Areview of post-war social policy first establishes the significanceof these terms, both individually and in varying combinations.Subsequently, the phrase as a whole provides the focus for acontent analysis of the three constituents of the PrescribedCurriculum, namely, the Secretary of State’s Requirementsfor Social Work Training, the employment-focussed National OccupationalStandards for Social Work, and the academically oriented BenchmarkStatement for Social Work. With the exception of ‘abuse’,the key terms are all registered, albeit unevenly. This presenceis subsequently enhanced via strategic considerations of ‘logicalimportance’ and ‘organising rubrics’. Finally,terminological variants of ‘abuse’ are traced, withparticular regard to the emerging language of ‘rights’.     

Cross‐Race Preferences for Same‐Race Faces Extend Beyond the African Versus Caucasian Contrast in 3‐Month‐Old Infants

A visual preference procedure was used to examine preferences among faces of different ethnicities (African, Asian, Caucasian, and Middle Eastern) in Chinese 3‐month‐old infants exposed only to Chinese faces. The infants demonstrated a preference for faces from their own ethnic group. Alongside previous results showing that Caucasian infants exposed only to Caucasian faces prefer same‐race faces (Kelly et al., 2005) and that Caucasian and African infants exposed only to native faces prefer the same over the other‐race faces (Bar‐Haim, Ziv, Lamy, & Hodes, 2006), the findings reported here (a) extend the same‐race preference observed in young infants to a new race of infants (Chinese), and (b) show that cross‐race preferences for same‐race faces extend beyond the perceptually robust contrast between African and Caucasian faces.     

Personal value of alcohol use as a predictor of intention to decrease post-college alcohol use.

This study examines the utility of a new measure of personal value of alcohol use in predicting intentions to reduce post-college alcohol use. This measure is intended to distinguish college students who drink due to situational norms versus intrinsic commitment to alcohol use. As expected, alcohol consumption quantity/frequency and frequency of consuming five or more drinks per occasion were unrelated to intention to reduce alcohol use after college. When these alcohol consumption measures were controlled using partial correlation, the personal value of alcohol measure was significantly and negatively related to intention to reduce alcohol use. Conversely, when personal value of alcohol use was controlled in partial correlations, the relationship between alcohol consumption variables and intention to reduce alcohol use after college became positive, though only at marginally significant levels. Implications are discussed.
