Emotional Distress in a Marginalized Population as a Function of Household-Level Social Determinants of Health.

Low-income, underrepresented communities of color are disproportionally affected by emotional distress. Little is known about malleable, household-level determinants of emotional distress, addressable by feasible, stigma-neutral interventions. The present study addressed this knowledge gap by analyzing secondary data from a cross-sectional community needs assessment survey in a marginalized urban community (N = 677). Relying on dominance analyses, authors found that, on average, the largest household-level contributions to respondents' emotional distress included exposures to fellow household members' alcohol use and anger-driven behaviors. Both determinants are arguably feasible to address via household-level interventions and community-level preventive efforts. Household members' physical and serious mental illness and drug use were moderately associated with respondents' emotional distress; household cohesion and communications, residential overcrowding, and child behavior played a minimal role. Article concludes with a discussion of public health implications of the results.

Delivering Food Resources and Kitchen Skills (FoRKS) to Adults with Food Insecurity and Hypertension: A Pilot Study.

Food insecurity affects nearly 50 million Americans and is linked to cardiovascular disease risk factors and health disparities. The purpose of this single-arm pilot study was to determine the feasibility of a 16-week dietitian-led lifestyle intervention to concurrently address food access, nutrition literacy, cooking skills, and hypertension among safety-net primary care adult patients. The Food Resources and Kitchen Skills (FoRKS) intervention provided nutrition education and support for hypertension self-management, group kitchen skills and cooking classes from a health center teaching kitchen, medically tailored home-delivered meals and meal kits, and a kitchen toolkit. Feasibility and process measures included class attendance rates and satisfaction and social support and self-efficacy toward healthy food behaviors. Outcome measures included food security, blood pressure, diet quality, and weight. Participants (n = 13) were on average {mean (SD)} aged 58.9 ± 4.5 years, 10 were female, and 12 were Black or African American. Attendance averaged 19 of 22 (87.1%) classes and satisfaction was rated as high. Food self-efficacy and food security improved, and blood pressure and weight declined. FoRKS is a promising intervention that warrants further evaluation for its potential to reduce cardiovascular disease risk factors among adults with food insecurity and hypertension.

Socioeconomic Stability Buffers Racial Discrimination Effect on Depression in a Marginalized Community.

Depression disproportionately burdens poverty-affected minority communities. Racism and racial discrimination are well-known determinants of depression among members of marginalized minority communities. Less is known about potential buffers of the discrimination effects on depression, particularly those that could serve as targets for efficient community-based policies and interventions. Our secondary analysis of data from a community needs assessment survey (N = 677) in an urban minority neighborhood of low socio-economic status revealed that high school completion and current employment significantly weakened the association between discrimination and depression. Our findings frame community-level efforts to foster high school completion and employment as potential strategies to reduce the footprint of racism on the mental health of marginalized community members. Implications for future research and policy are discussed.

A Randomized Intervention of Supplemental Nutrition Assistance Program-Education Did Not Improve Dietary Outcomes Except for Vitamin D Among Lower-Income Women in Indiana.

BACKGROUND: The goal of US Department of Agriculture Supplemental Nutrition Assistance Program-Education (SNAP-Ed) is to improve the likelihood that those eligible for SNAP will make healthy choices aligned with the Dietary Guidelines for Americans, 2020-2025. OBJECTIVE: The objective of the study was to evaluate the long-term effects of a direct SNAP-Ed intervention in which participants actively engage in learning with educator instruction about dietary quality and usual intake of key nutrient and food groups among Indiana SNAP-Ed-eligible women participants as an example sample in the context of no similar existing evaluation. DESIGN: The study design was a parallel-arm, randomized controlled, nutrition education intervention, with follow-up at 1 year. PARTICIPANTS/SETTING: Participants (18 years and older; n = 97 women) eligible for SNAP-Ed and interested in receiving nutrition education lessons were recruited from 31 Indiana counties from August 2015 to May 2016 and randomized to an intervention (n = 53) or control (n = 44) group. INTERVENTION: The intervention comprised core lessons of Indiana SNAP-Ed delivered between 4 and 10 weeks after baseline assessment. Each participant completed a baseline and 1-year follow-up assessment. Dietary intake was assessed using repeated 24-hour dietary recalls (up to 2). MAIN OUTCOME MEASURES: Mean usual nutrient, food group intake, diet quality (ie, Healthy Eating Index-2010 scores), and proportion of intervention and control groups meeting Dietary Guidelines for Americans, 2020-2025 recommendations and Dietary Reference Intake indicators of requirement or adequacy, were determined using the National Cancer Institute method and the simple Healthy Eating Index-2010 scoring algorithm method. Dietary changes between intervention and control groups were examined over time using mixed linear models. STATISTICAL ANALYSES PERFORMED: Bonferroni-corrected significance levels were applied to the results of the mixed linear models for comparisons of usual intake of nutrients and foods. RESULTS: No differences in diet quality, intake of food group components, food group intake, or nutrients were observed at 1-year follow-up, except that vitamin D intake was higher among those who received SNAP-Ed compared with the control group. CONCLUSIONS: A direct SNAP-Ed intervention did not improve diet quality, food group intake, or key nutrient intake, except for vitamin D, among Indiana SNAP-Ed-eligible women up to 1 year after the nutrition education.

Supplemental Nutrition Assistance Program-Education Improves Food Security Independent of Food Assistance and Program Characteristics.

The purpose of this project was to determine whether consistent food assistance program participation or changes in participation over time mediated or moderated the effect of federal nutrition education through the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) on food security and determine the associations of SNAP-Ed program delivery characteristics with change in food security. This secondary analysis used data from a randomized controlled trial from September 2013 through April 2015. SNAP-Ed-eligible participants (n = 328; ≥18 years) in households with children were recruited from 39 counties in Indiana, USA. The dependent variable was one year change in household food security score measured using the United States Household Food Security Survey Module. Assessment of mediation used Barron-Kenny analysis and moderation used interactions of food assistance program use and changes over time with treatment group in general linear regression modeling. Program delivery characteristics were investigated using mixed linear regression modeling. Results showed that neither consistent participation nor changes in food assistance program participation over time mediated nor moderated the effect of SNAP-Ed on food security and neither were SNAP-Ed program delivery characteristics associated with change in food security over the one year study period. SNAP-Ed directly improved food security among SNAP-Ed-eligible Indiana households with children regardless of food assistance program participation and changes over time or varying program delivery characteristics.

Dietary Quality and Usual Intake of Underconsumed Nutrients and Related Food Groups Differ by Food Security Status for Rural, Midwestern Food Pantry Clients.

BACKGROUND: Food pantry users represent a predominantly food insecure population, yet dietary intake may differ among food secure (FS), low FS, and very low FS clients. Usual intake of food groups and nutrients by food security status has not previously been compared among food pantry clients. OBJECTIVE: This study aimed to estimate the usual intakes of underconsumed nutrients (ie, potassium; dietary fiber; choline; magnesium; calcium; vitamins A, D, E, and C; and iron) and related food groups (ie, vegetables, fruits, whole grains, and dairy) and dietary quality, and to evaluate their relationship with food security status. DESIGN: This cross-sectional, secondary analysis used baseline data from a prior intervention study (Clinical Trial Registry: NCT03566095). A demographic questionnaire, the US Household Food Security Survey Module, and up to three 24-hour dietary recalls on nonconsecutive days, including weekdays and weekends, were collected. PARTICIPANTS/SETTING: This community-based study included a convenience sample of adult, midwestern food pantry clients (N=579) recruited from August to November 2014. MAIN OUTCOME MEASURES: Main outcomes evaluated were Healthy Eating Index-2010 scores and usual intakes of underconsumed nutrients and related food groups. STATISTICAL ANALYSES PERFORMED: Linear regression models and the National Cancer Institute method, adjusting for confounders, were used to estimate associations of food security with diet quality and usual intake, respectively. RESULTS: Being FS was associated with a higher whole grains HEI-2010 score and higher mean usual intake of whole grains compared with being low FS. Being FS was associated with higher usual intakes of iron and dairy compared with being very low FS. Being FS was associated with a higher mean usual intake of dark green vegetables compared with being low FS and very low FS. Usual intakes were below federal guidance for all subgroups of food security. CONCLUSIONS: Although food security status may differentiate dietary intake among food pantry clients, improvements are needed among all clients.

The role of staffing and classroom characteristics on preschool teachers' use of one-to-one intervention with children with autism.

LAY ABSTRACT: For preschool children with autism, individual (one-to-one) behavioral interventions are among the best-tested treatments. However, they are rarely used in special education preschools. We observed formally and informally delivered one-to-one behavioral interventions use by classroom staff (n = 51) in 12 classrooms across three special education preschools for children with autism, aged 3-6 years, in a major US city. We estimated the associations between one-to-one intervention use and classroom characteristics including staff-student ratio, professional role composition, and frequency of challenging child behaviors. As a whole, the factors we examined were considerably important for both formally and informally delivered one-to-one interventions. The number of individually assigned personal care aides in the classroom was negatively associated with the use of formally delivered one-to-one intervention. Classroom challenging behavior was positively associated with use of formally delivered one-to-one interventions. Interventionist's professional roles and the number of children in the class were most important for the use of informally delivered interventions. Staff training, clarifying professional roles, setting performance expectations for personal care aides and other classroom team members, and reducing class size may represent promising implementation targets. Findings suggest caution around task-shifting policies that transfer clinical functions from more highly trained to less highly trained staff.

Diet Quality and Associations with Food Security among Women Eligible for Indiana Supplemental Nutrition Assistance Program-Education.

BACKGROUND: The diet quality among adults receiving nutrition education lessons through Supplemental Nutrition Assistance Program-Education (SNAP-Ed) is currently unknown. OBJECTIVES: The objectives of this study were to characterize the diet quality of Indiana SNAP-Ed-eligible women; estimate their mean usual intake of fruits, vegetables, dairy, and whole grains compared to Dietary Guidelines for Americans (DGA) recommendations; and determine if these dietary outcomes differed by food security status. METHODS: SNAP-Ed paraprofessionals recruited participants from August 2015 to May 2016 for this secondary analysis of cross-sectional data collected as the baseline assessment for a randomized controlled trial. Participants were SNAP-Ed-eligible women aged ≥18 y interested in nutrition education lessons. Dietary outcomes were assessed by one or two 24-h dietary recalls. The Healthy Eating Index (HEI)-2010 was used to characterize diet quality. Mean usual intake of food groups was estimated using the National Cancer Institute Method. Food security status was classified using the US Household Food Security Survey Module. Data were analyzed in October 2019. RESULTS: Mean ± SEM HEI-2010 total score was 42 ± 0.9 for the study sample. Mean ± SE usual intake of servings of fruits (0.61 ± 0.08 cups [144.32 ± 18.93 mL]), vegetables [1.4 ± 0.10 cups (331.2 ± 23.66 mL)], dairy [1.5 ± 0.11 cups (354.88 ± 26.02 mL)], and whole grains [0.48 ± 0.06 ounces (13.61 ± 1.70 g)] did not differ by food security subgroup. Mean HEI-2010 total score was significantly higher by 4.8 ± 2.0 points for the food-secure than for the food-insecure subgroup (P = 0.01). Mean HEI-2010 component scores were 1.1 ± 0.5 points higher for whole grain (P = 0.01) and 1.0 ± 0.5 points higher for dairy (P = 0.05) in the food-secure than in the food-insecure subgroup. The proportions of the study sample not meeting the DGA recommendations for food group intake were ≥85% for both food-secure and -insecure subgroups. CONCLUSIONS: Indiana SNAP-Ed-eligible women reported poor diet quality, highlighting their need for nutrition interventions aiming to improve food security and diet as per DGA recommendations in low-income populations.

Playful but Mindful: How to Best Use Positive Affect in Treating Toddlers With Autism.

The best-tested treatments for toddlers with autism spectrum disorder (ASD) are grounded in the principles of applied behavioral analysis (ABA) and blended with developmental science. Examples include Project ImPACT1 and Early Start Denver Model,2 among others. ABA-based behavioral interventions use conditioned reinforcement of target behaviors by giving the child access to desired objects and activities as a consequence of performing target behaviors. Unlike the original ABA technique, discrete trial training, ABA-based naturalistic developmental-behavioral interventions (NDBIs) occur in natural environments and employ operant conditioned reinforcement of target behaviors by capitalizing on the child's interests in objects and activities.1-3 NDBIs are highly recommended for toddlers and children with autism.3 Clinical manuals for NDBIs emphasize that clinicians should use modulations of voice and exaggerated facial expressions and gestures to engage toddlers.1-4 These behaviors are often referred to as positive affect, increased animation, modulation of child affect, or playfulness. Given the range of clinician behaviors described across these constructs and the commonalities between them, within this article we will henceforth refer to the following behaviors as playfulness: positive affect, increased animation, modulation of child affect, and exaggerated facial expressions and gestures. Most NDBIs indicate that playfulness should be thoughtfully employed throughout NDBI sessions in conjunction with other NDBI strategies (eg, contingent responsiveness, balanced turns, child choice) to maintain engagement and build social reciprocity with the child as the clinician and child work together toward treatment goals. However, our clinical and supervisory experiences suggest that many clinicians do not consistently use playfulness as an intervention tool. Instead, according to our observations, many clinicians largely employ neutral affect when providing treatment to toddlers with ASD, even while employing NDBI strategies such as following the child's lead, contingent responsiveness, and balanced turns. This article presents our clinical perspective on the utility of playfulness for treating toddlers with ASD.

Effect of Supplemental Nutrition Assistance Program-Education (SNAP-Ed) on food security and dietary outcomes.

The Supplemental Nutrition Assistance Program-Education (SNAP-Ed) is the nutrition promotion component of SNAP, formerly known as food stamps. SNAP-Ed assists low-income populations in the United States improve dietary intake and reduce food insecurity through nutrition education. This narrative review summarizes current investigations of SNAP-Ed's effectiveness at improving food security and dietary outcomes, and it can help inform future policy and implementation of the program. There was stronger evidence for SNAP-Ed as an effective means of improving food security (n = 4 reports) than for its effects on nutrition or dietary outcomes (n = 10 reports). Inconsistency in measurement tools and outcomes and a lack of strong study designs characterized the studies that sought to evaluate the effectiveness of SNAP-Ed at improving nutrition or dietary outcomes. Additional rigorous study designs in diverse population groups are needed to strengthen the evidence. In the face of reduced financial SNAP benefits, SNAP-Ed may play an important role in helping to eliminate food insecurity and improve dietary outcomes and, ultimately, the health of low-income Americans.

PHYLOGENETIC ANALYSIS OF THE GENOME OF AN ENTERITIS-ASSOCIATED BOTTLENOSE DOLPHIN MASTADENOVIRUS SUPPORTS A CLADE INFECTING THE CETARTIODACTYLA.

: Adenoviruses are nonenveloped, double-stranded DNA viruses, known to infect members of all tetrapod classes, with a similarity between phylogenies of hosts and viruses observed. We characterized bottlenose dolphin adenovirus 2 (BdAdV-2) found in a bottlenose dolphin ( Tursiops truncatus) with enteritis. Virions were seen by negative staining electron microscopy of feces. Initial sequences obtained using conserved PCR primers were expanded using primer walking techniques, and the complete coding sequence was obtained. Phylogenetic analyses were consistent with coevolution of this virus and its bottlenose dolphin host, placing BdAdV-2 into a monophyletic group with other mastadenoviruses of Cetartiodactyla. When considering the low guanine/cytosine (G/C) content of BdAdV-2 with the phylogenetic data, this virus may represent a host-jumping event from another member of Cetartiodactyla. Analysis of partial polymerase indicated that bottlenose dolphin adenovirus 1, previously identified in Spain, and BdAdV-2 are sister taxa with harbor porpoise adenovirus 1, forming a cetacean clade. Bottlenose dolphin adenovirus 2 includes a highly divergent fiber gene. Two genes homologous to the dUTPase superfamily are also present which could play a role in enabling viral replication in nondividing cells. We used sequence data to develop a probe hybridization quantitative PCR assay specific to BdAdV-2 with a limit of detection of 10 copies.

Exploring the association of urban or rural county status and environmental, nutrition- and lifestyle-related resources with the efficacy of SNAP-Ed (Supplemental Nutrition Assistance Program-Education) to improve food security.

OBJECTIVE: To investigate the association of policy, systems and environmental factors with improvement in household food security among low-income Indiana households with children after a Supplemental Nutrition Assistance Program-Education (SNAP-Ed) direct nutrition education intervention. DESIGN: Household food security scores measured by the eighteen-item US Household Food Security Survey Module in a longitudinal randomized and controlled SNAP-Ed intervention study conducted from August 2013 to April 2015 were the response variable. Metrics to quantify environmental factors including classification of urban or rural county status; the number of SNAP-authorized stores, food pantries and recreational facilities; average fair market housing rental price; and natural amenity rank were collected from government websites and data sets covering the years 2012-2016 and used as covariates in mixed multiple linear regression modelling. SETTING: Thirty-seven Indiana counties, USA, 2012-2016. SUBJECTS: SNAP-Ed eligible adults from households with children (n 328). RESULTS: None of the environmental factors investigated were significantly associated with changes in household food security in this exploratory study. CONCLUSIONS: SNAP-Ed improves food security regardless of urban or rural location or the environmental factors investigated. Expansion of SNAP-Ed in rural areas may support food access among the low-income population and reduce the prevalence of food insecurity in rural compared with urban areas. Further investigation into policy, systems and environmental factors of the Social Ecological Model are warranted to better understand their relationship with direct SNAP-Ed and their impact on diet-related behaviours and food security.

Development and validation of a quantitative PCR for rapid and specific detection of California sea lion adenovirus 1 and prevalence in wild and managed populations.

California sea lion adenovirus 1 (CSLAdV-1) has been associated with hepatitis and enteritis in several wild and captive populations of diverse pinniped species. Currently available tests have been limited to pan-adenoviral polymerase chain reaction (PCR) followed by sequencing. We present the development of a quantitative probe-hybridization PCR (qPCR) assay for rapid, sensitive, and specific detection of this virus in California sea lions ( Zalophus californianus) and other pinnipeds. This assay did not amplify other mammalian adenoviruses and is able to detect consistently down to 10 viral copies per well. Compared with the gold standard conventional pan-adenovirus PCR/sequencing assay, diagnostic sensitivity and specificity of 100% and 88.2% were found, respectively. The lower diagnostic specificity of this qPCR assay may be the result of the lower limit of detection of this assay compared with the gold standard rather than the result of detection of true false-positives.

SNAP-Ed (Supplemental Nutrition Assistance Program-Education) Increases Long-Term Food Security among Indiana Households with Children in a Randomized Controlled Study.

BACKGROUND: Food insecurity is negatively associated with US children's dietary intake and health. The Supplemental Nutrition Assistance Program-Education (SNAP-Ed) aims to alleviate food insecurity by offering nutrition, budgeting, and healthy lifestyle education to low-income individuals and families. OBJECTIVE: The objective of this study was to evaluate the long-term impact of the Indiana SNAP-Ed on food security among households with children. METHODS: A randomized, controlled, parallel study design with SNAP-Ed as an intervention was carried out during a 4- to 10-wk intervention period. Intervention group participants received the first 4 Indiana SNAP-Ed curriculum lessons. Study participants (n = 575) were adults aged ≥18 y from low-income Indiana households with ≥1 child living in the household. Both treatment groups completed an assessment before and after the intervention period and 1 y after recruitment. The 18-item US Household Food Security Survey Module was used to classify the primary outcomes of food security for the household and adults and children in the household. A linear mixed model was used to compare intervention with control group effects over time on food security. RESULTS: Mean ± SEM changes in household food security score and food security score among household adults from baseline to 1-y follow-up were 1.2 ± 0.4 and 0.9 ± 0.3 units lower, respectively, in the intervention group than in the control group (P < 0.01). The mean change in food security score from baseline to 1-y follow-up among household children was not significantly different in the intervention group compared with the control group. CONCLUSIONS: SNAP-Ed improved food security over a longitudinal time frame among low-income Indiana households with children in this study. SNAP-Ed may be a successful intervention to improve food security.

The Macronutrients, Appetite, and Energy Intake.

Each of the macronutrients-carbohydrate, protein, and fat-has a unique set of properties that influences health, but all are a source of energy. The optimal balance of their contribution to the diet has been a long-standing matter of debate. Over the past half century, thinking has progressed regarding the mechanisms by which each macronutrient may contribute to energy balance. At the beginning of this period, metabolic signals that initiated eating events (i.e., determined eating frequency) were emphasized. This was followed by an orientation to gut endocrine signals that purportedly modulate the size of eating events (i.e., determined portion size). Most recently, research attention has been directed to the brain, where the reward signals elicited by the macronutrients are viewed as potentially problematic (e.g., contribute to disordered eating). At this point, the predictive power of the macronutrients for energy intake remains limited.

The Effects of Increased Protein Intake on Fullness: A Meta-Analysis and Its Limitations.

BACKGROUND: Higher protein intake has been implicated in weight management because of its appetitive properties. However, the effects of protein intake on appetitive sensations such as fullness have not been systematically assessed. Meta-analysis is a useful technique to evaluate evidence of an intervention's effect on testable outcomes, but it also has important limitations. OBJECTIVE: The primary aim of this study was to synthesize the available evidence on the effect of protein intake on fullness using a quantitative meta-analysis and a secondary directional analysis using the vote-counting procedure. A tertiary aim was to address limitations of meta-analyses as they pertain to findings from this meta-analysis. DESIGN: We searched multiple databases for interventional studies that evaluated the effect of increased protein intake on fullness ratings. Inclusion criteria for both analyses were as follows: healthy human participants, preload studies that utilized intact dietary protein, delivery of protein load orally, and studies reporting fullness as an outcome. For the meta-analysis, an additional criterion was that the studies also needed to report 2- to 4-hour area under the curve value for fullness. RESULTS: Five studies met all criteria for the meta-analysis. Twenty-eight studies met all criteria for the directional analysis. The meta-analysis indicated higher protein preloads have a greater effect on fullness than lower protein preloads (overall effect estimate: 2,435.74 mm.240 min, (95% CI 1,375.18 to 3,496.31 mm.240 min; P<0.0001). The directional analysis also revealed a positive effect on fullness with higher protein preloads (P<0.01). Many related scientifically rigorous studies were excluded from the analysis because analytical criteria required a narrowly focused research question. CONCLUSIONS: The present analyses show that higher protein preloads increase fullness ratings more than lower protein preloads under tightly defined conditions. Extrapolation of findings to common conditions outside the specified criteria of this analysis must be made cautiously, as must speculation about the influence of fullness sensations on ingestive behavior, body weight, and various health outcomes.

Phylogenomic characterization of California sea lion adenovirus-1.

Significant adenoviral diversity has been found in humans, but in domestic and wild animals the number of identified viruses is lower. Here we present the complete genome of a recently discovered mastadenovirus, California sea lion adenovirus 1 (CSLAdV-1) isolated from California sea lions (Zalophus californianus), an important pathogen associated with hepatitis in pinnipeds. The genome of this virus has the typical mastadenoviral structure with some notable differences at the carboxy-terminal end, including a dUTPase that does not cluster with other mastadenoviral dUTPases, and a fiber that shows similarity to a trans-sialidase of Trypanosoma cruzi and choline-binding protein A (CbpA) of Streptococcus pneumoniae. The GC content is low (36%), and phylogenetic analyses placed the virus near the root of the clade infecting laurasiatherian hosts in the genus Mastadenovirus. These findings support the hypothesis that CSLAdV-1 in California sea lions represents a host jump from an unknown mammalian host in which it is endemic.

Ethnicity and acculturation: do they predict weight status in a longitudinal study among Asian, Hispanic, and non-Hispanic White early adolescent females?

BACKGROUND: The prevalence of overweight and obesity among adolescents has increased over the past decade. Prevalence rates are disparate among certain racial and ethnic groups. This study sought to longitudinally examine the relationship between overweight status (≥85th percentile according to the Centers for Disease Control and Prevention growth charts) and ethnic group, as well as acculturation (generation and language spoken in the home) in a sample of adolescent females. METHODS: Asian (n=160), Hispanic (n=217), and non-Hispanic White (n=304) early adolescent girls participating in the multistate calcium intervention study with complete information on weight, ethnicity, and acculturation were included. Multiple methods of assessing longitudinal relationships (binary logistic regression model, linear regression model, Cox proportional-hazards regression analysis, and Kaplan-Meier survival analysis) were used to examine the relationship. RESULTS: The total proportion of girls overweight at baseline was 36%. When examining by ethnic group, the proportion varied with Hispanic girls having the highest percentage (46%) in comparison to their Asian (23%) and Non-Hispanic White (35%) counterparts. Although the total proportion of overweight was 36% at 18 months, the variation across the ethnic groups remained with the proportion of Hispanic girls becoming overweight (55%) being greater than their Asian (18%) and non-Hispanic White (34%) counterparts. However, regardless of the statistical approach used, there were no significant associations between overweight status and acculturation over time. CONCLUSION: These unexpected results warrant further exploration into factors associated with overweight, especially among Hispanic girls, and further investigation of acculturation's role is warranted. Identifying these risk factors will be important for developing targeted obesity prevention initiatives.

Serologic response of harbor seals (Phoca vitulina) to vaccination with a recombinant canine distemper vaccine.

Morbilliviruses pose a significant threat to marine mammal populations around the world and have been associated with multiple epizootics in pinnipeds and cetaceans. As part of a preventive veterinary medical program, five harbor seals (Phoca vitulina) in a managed collection were vaccinated with a recombinant canarypox-vectored canine distemper virus vaccine. The vaccine was evaluated for safety (by monitoring seals for local and systemic adverse effects and by testing for shedding of the canarypox vector) and efficacy (by testing for serum neutralizing antibodies). None of the seals showed signs of local or systemic adverse reactions to the vaccination. Three seals vaccinated once did not seroconvert, but the recombinant vaccine induced a persistent serum virus neutralizing titer (12 mo) in the two seals that were vaccinated twice, 1 mo apart.
