Logistic regression models assessed if discrimination at various locations was associated with food insecurity and linear models assessed how racial discrimination was associated with physical health, stress and grade point average RESULTS: Student's experiencing food security had an average discrimination score of 2.

Background: Assess the associations between ten severe maternal hardships and food insecurity experienced during pregnancy.

Methods: Data on 14,274 low-income/lower-income women (below 400% of the income to federal poverty guideline ratio) from the statewide-representative 2010-2012 California Maternal and Infant Health Assessment were used to estimate food security status prevalence.

Restaurant delivery services have gained in popularity among college students; however, students participating in the Supplemental Nutrition Assistance Program (SNAP) are not allowed to redeem their benefits via restaurant delivery services. This mixed-methods head-to-head crossover trial assessed whether college students experiencing marginal food security prefer benefits via a grocery store gift card (as a proxy for traditional SNAP benefits) or via a restaurant delivery service gift card of equivalent value, and which type of benefit is more effective at improving food security status. Thirty college students experiencing marginal food security were recruited to receive $80 in cash equivalent benefits to spend over a two-month period in the form of grocery store gift cards and restaurant delivery service gift cards.

Objective: Food security status is a continuum ranging from high to very low food security. While marginal food security falls next to high food security on the spectrum, new quantitative research indicates marginal food security status is associated with negative health outcomes and poor academic performance among college students. Qualitative research focusing on college students experiencing marginal food security has not been conducted.

Background: Persistent household food insecurity may have a greater adverse effect on children's health outcomes than experiencing household food insecurity for a shorter duration.

Objectives: Examine how changing household food security status and prolonged exposure to household marginal food security or food insecurity are associated with changes in children's growth from age 5 to 12.

Methods: We analyzed 204 mother-child dyads from the Center for Health Assessment of Mothers and Children of Salinas (CHAMACOS), a longitudinal birth cohort study of Latino households.

Early life exposures have been associated with obesity later in life. We aim to assess the association between early life exposure to food insecurity and change in BMI throughout childhood and adolescents. Food security status and growth variables from 243 Mother-child dyads from the Center for the Health Assessment of Mothers and Children of Salinas study were assessed 7 times over a 12-year period.

Student-faculty (S-F) interactions that are conducive to students' learning can help reduce the retention and graduation gaps in higher education, especially for college students from underrepresented and underprivileged backgrounds. The aim of the study was to explore students' perceptions of their interactions with faculty, and the subjective impact of these interactions on students' academic and personal life. We analyzed qualitative data from a larger study with the goal of providing best practice models to support students experiencing displacement and food insecurity.

We identified fifty-one peer-reviewed studies that geospatially analyzed the relationship between the community nutrition environment (CNE) and obesity. Eighty percent of studies found at least one significant association between the CNE and obesity. However we calculated the proportion of studies that found at least one significant association between the CNE and obesity in the expected direction for each food store type and measurement technique, and the proportion across the different store types and measurement techniques was just 32%.

Background: Effective treatments for obsessive-compulsive disorder (OCD) include behavioral therapy (exposure and response/ritual prevention and cognitive behavioral therapy) and serotonin-reuptake inhibitors (SRIs); however, the relative efficacy of these treatments is not well established. We sought to review evidence from head-to-head randomized-controlled trials (RCTs) of behavioral therapy and SRIs in the treatment of OCD.

Methods: A systematic search of multiple databases was conducted from first available date to June 30, 2012, for RCTs in the treatment of OCD among outpatients, comparing behavioral therapy and SRIs, alone or combined.
