RESUMO

Faith-based organizations (FBOs) are often "gatekeepers" to mental health care for congregants at risk of mental illness and suicide, especially U.S. military Veterans, but data to inform better collaboration are needed. We conducted focus groups with clergy in Los Angeles County to understand the mental health support FBOs provide and barriers to collaboration with the mental healthcare system. Clergy detailed strategies used to support the mental health of Veteran congregants. Barriers included stigma, limits in clergy training, and incomplete knowledge about community and VA mental health resources. Results suggest strategies to improve collaboration between FBOs and the mental healthcare system in Los Angeles County.

RESUMO

Relationships between the absorption and backscattering coefficients of marine optical constituents and ocean color, or remote sensing reflectances Rrs(λ), can be used to predict the concentrations of these constituents in the upper water column. Standard inverse modeling techniques that minimize error between the modeled and observed Rrs(λ) break down when the number of products retrieved becomes similar to, or greater than, the number of different ocean color wavelengths measured. Furthermore, most conventional ocean reflectance inversion approaches, such as the default configuration of NASA's Generalized Inherent Optical Properties algorithm framework (GIOP-DC), require a priori definitions of absorption and backscattering spectral shapes. A Bayesian approach to GIOP is implemented here to address these limitations, where the retrieval algorithm minimizes both the error in retrieved ocean color and the deviation from prior knowledge, calculated using output from a mixture of empirically-derived and best-fit values. The Bayesian approach offers potential to produce an expanded range of parameters related to the spectral shape of absorption and backscattering spectra.

RESUMO

OBJECTIVE: To evaluate trends in the incidence of premenopausal unilateral and bilateral oophorectomy between 1950 and 2018. METHODS: The Rochester Epidemiology Project medical records-linkage system was used to identify all women aged 18-49 years who were residents of Olmsted County, Minnesota, and underwent unilateral or bilateral oophorectomy before spontaneous menopause between January 1, 1950, and December 31, 2018. Population denominators were derived from the U.S. Decennial Censuses for the years 1950-2010, and intercensal year population denominators were linearly interpolated. For 2011-2018, the annual population denominators were obtained from the U.S. Census projections. Where appropriate, overall incidence rates were age-adjusted to the total U.S. female population from the 2010 Census. RESULTS: There were 5,154 oophorectomies in Olmsted County across the 69-year period between 1950 and 2018, and 2.9% showed malignant disease on pathology. A total of 2,092 (40.6%) women underwent unilateral oophorectomy, and 3,062 (59.4%) women underwent bilateral oophorectomy. More than half (n=1,750, 57.2%) of the bilateral oophorectomies occurred between 1990 and 2009. Until 1975-1979, the incidence of unilateral oophorectomy was mostly higher than bilateral oophorectomy. From 1980-1984 until 2000-2004, the incidence of bilateral oophorectomy more than doubled and the incidence of unilateral oophorectomy declined. After 2005, both procedures declined and converged to a similar incidence in 2015-2018. The decline in premenopausal bilateral oophorectomy over the past 14 years (2005-2018) was most pronounced for women who underwent oophorectomy concurrently with hysterectomy or did not have any ovarian indication. CONCLUSION: The incidence rates of unilateral and bilateral oophorectomy have varied greatly across the 69-year period of this study. In the past 14 years, the incidence of premenopausal unilateral and bilateral oophorectomy has decreased. These trends reflect the effects of the initial 2005-2006 publications and the subsequent expanding body of evidence against the practice of oophorectomy for noncancer indications.

RESUMO

Moral injury is a complex phenomenon characterized by spiritual, psychological, and moral distress caused by actions or acts of omission inconsistent with an individual's moral and ethical values. We present two cases from an ongoing randomized controlled trial of a spiritually integrated structured intervention delivered by chaplains for individuals suffering from moral injury. Chaplains met with Veterans for twelve 50-min sessions that each focused on a specific domain of moral injury. Participants were asked to complete validated scales assessing symptoms of moral injury and PTSD, including the PTSD Checklist for DSM-5 (PCL-5), Moral Injury Symptom Scale-Military Version Short Form, and Moral Injury Symptom Scale-Military Version Long Form. We report on two Veterans who completed the intervention and demonstrated significant improvement in moral injury and PTSD symptoms.

RESUMO

Cell abundances of Prochlorococcus, Synechococcus, and autotrophic picoeukaryotes were estimated in surface waters using principal component analysis (PCA) of hyperspectral and multispectral remote-sensing reflectance data. This involved the development of models that employed multilinear correlations between cell abundances across the Atlantic Ocean and a combination of PCA scores and sea surface temperatures. The models retrieve high Prochlorococcus abundances in the Equatorial Convergence Zone and show their numerical dominance in oceanic gyres, with decreases in Prochlorococcus abundances towards temperate waters where Synechococcus flourishes, and an emergence of picoeukaryotes in temperate waters. Fine-scale in-situ sampling across ocean fronts provided a large dynamic range of measurements for the training dataset, which resulted in the successful detection of fine-scale Synechococcus patches. Satellite implementation of the models showed good performance (R2 > 0.50) when validated against in-situ data from six Atlantic Meridional Transect cruises. The improved relative performance of the hyperspectral models highlights the importance of future high spectral resolution satellite instruments, such as the NASA PACE mission's Ocean Color Instrument, to extend our spatiotemporal knowledge about ecologically relevant phytoplankton assemblages.

RESUMO

Current methods to retrieve optically relevant properties from ocean color observations do not explicitly make use of prior knowledge about property distributions. Here we implement a simplified Bayesian approach that takes into account prior probability distributions on two sets of five optically relevant parameters, and conduct a retrieval of these parameters using hyperspectral simulated water-leaving reflectances. We focus specifically on the ability of the model to distinguish between two optically similar phytoplankton taxa, diatoms and Noctiluca scintillans. The inversion retrieval gives most-likely concentrations and uncertainty estimates, and we find that the model is able to probabilistically predict the occurrence of Noctiluca scintillans blooms using these metrics. We discuss how this method can be expanded to include a priori covariances between different parameters, and show the effect of varying measurement uncertainty and spectral resolution on Noctiluca scintillans bloom predictions.

RESUMO

Determinants of lifetime health are complex and emphasize the need for robust predictors of disease risk. Allostatic load (AL) has become a clinical framework to estimate the cumulative biological burden associated with chronic stress. To assist knowledge translation in the developmental origins of health and disease field, clinically valid methods for reliable AL assessment in experimental models are urgently needed. Here, we introduce the rat cumulative allostatic load measure (rCALM), as a new preclinical knowledge translation tool to assess the burden of chronic stress. First, we identified an array of stress-associated physiological markers that are particularly sensitive to hypothalamic-pituitary-adrenal axis dysregulation by ancestral prenatal stress. Second, we determined which of these markers are susceptible to an intervention by environmental enrichment (EE) to mitigate AL. The markers most responsive to stress and EE therapy were assembled to become operationalized in the rCALM. Third, the new rCALM was validated for the ability to indicate future disease risks. The results show that the rCALM estimates the burden of chronic stress and serves as a proxy to estimate stress resilience and vulnerability to disease. Using the rCALM we showed that enrichment therapy can offset the adverse health outcomes linked to a high AL. Thus, the rCALM provides a model for the development of new test strategies that facilitate knowledge translation in preclinical animal models.

RESUMO

INTRODUCTION: There is growing evidence that moral injury (MI) is related to greater suicide risk among Veterans and Active Duty Military (V/ADM). This study examines the relationship between MI and suicide risk and the moderating effect of religiosity on this relationship in V/ADM with post-traumatic stress disorder (PTSD) symptoms. MATERIALS AND METHODS: This was a cross-sectional multi-site study involving 570 V/ADM from across the USA. Inclusion criteria were having served in a combat theater and the presence of PTSD symptoms. Multidimensional measures assessed MI, religiosity, PTSD symptoms, anxiety, and depression. In this secondary data analysis, a suicide risk index was created based on 10 known risk factors. Associations between MI and the suicide risk index were examined, controlling for demographic, religious, and military characteristics, and the moderating effects of religiosity were explored. RESULTS: MI overall was correlated strongly with suicide risk (r = 0.54), as were MI subscales (ranging from r = 0.19 for loss of trust to 0.48 for self-condemnation). Controlling for other characteristics had little effect on this relationship (B = 0.016, SE = 0.001, p < 0.0001). Religiosity was unrelated to suicide risk and did not moderate the relationship between suicide risk and MI or any of its subscales. CONCLUSION: MI is strongly and independently associated with risk factors for suicide among V/ADM with PTSD symptoms, and religiosity does not mediate or moderate this relationship. Whether interventions that target MI reduce risk of suicide or suicidal ideation remains unknown and needs further study.

RESUMO

Moral injury (MI) involves feelings of shame, grief, meaninglessness, and remorse from having violated core moral beliefs related to traumatic experiences. This multisite cross-sectional study examined the association between religious involvement (RI) and MI symptoms, mediators of the relationship, and the modifying effects of posttraumatic stress disorder (PTSD) severity in 373 US veterans with PTSD symptoms who served in a combat theater. Assessed were demographic, military, religious, physical, social, behavioral, and psychological characteristics using standard measures of RI, MI symptoms, PTSD, depression, and anxiety. MI was widespread, with over 90% reporting high levels of at least one MI symptom and the majority reporting at least five symptoms or more. In the overall sample, religiosity was inversely related to MI in bivariate analyses (r = -0.25, p < 0.0001) and multivariate analyses (B = -0.40, p = 0.001); however, this relationship was present only among veterans with severe PTSD (B = -0.65, p = 0.0003). These findings have relevance for the care of veterans with PTSD.

RESUMO

Introduction: To develop a short form (SF) of the 45-item multidimensional Moral Injury Symptom Scale - Military Version (MISS-M) to use when screening for moral injury and monitoring treatment response in veterans and active duty military with PTSD. Methods: A total of 427 veterans and active duty military with PTSD symptoms were recruited from VA Medical Centers in Augusta, GA; Los Angeles, CA; Durham, NC; Houston, TX; and San Antonio, TX; and from Liberty University, Lynchburg, Virginia. The sample was randomly split in two. In the first half (n = 214), exploratory factor analysis identified the highest loading item on each of the 10 MISS scales (guilt, shame, moral concerns, loss of meaning, difficulty forgiving, loss of trust, self-condemnation, religious struggle, and loss of religious faith) to form the 10-item MISS-M-SF; confirmatory factor analysis was then performed to replicate results in the second half of the sample (n = 213). Internal reliability, test-retest reliability, and convergent, discriminant, and concurrent validity were examined in the overall sample. The study was approved by the institutional review boards and the Research & Development (R&D) Committees at Veterans Administration medical centers in Durham, Los Angeles, Augusta, Houston, and San Antonio, and the Liberty University and Duke University Medical Center institutional review boards. Findings: The 10-item MISS-M-SF had a median of 50 and a range of 12-91 (possible range 10-100). Over 70% scored a 9 or 10 (highest possible) on at least one item. Cronbach's alpha was 0.73 (95% CI 0.69-0.76), and test-retest reliability was 0.87 (95% CI 0.79-0.92). Convergent validity with the 45-item MISS-M was r = 0.92. Discriminant validity was demonstrated by relatively weak correlations with social, religious, and physical health constructs (r = 0.21-0.35), and concurrent validity was indicated by strong correlations with PTSD, depression, and anxiety symptoms (r = 0.54-0.58). Discussion: The MISS-M-SF is a reliable and valid measure of MI symptoms that can be used to screen for MI and monitor response to treatment in veterans and active duty military with PTSD.

RESUMO

The purpose of this study was to develop a multi-dimensional measure of moral injury symptoms that can be used as a primary outcome measure in intervention studies that target moral injury (MI) in Veterans and Active Duty Military with PTSD. This was a multi-center study of 427 Veterans and Active Duty Military with PTSD symptoms recruited from VA Medical Centers in Augusta, Los Angeles, Durham, Houston, and San Antonio, and from Liberty University in Lynchburg. Internal reliability of the Moral Injury Symptom Scale-Military Version (MISS-M) was examined along with factor analytic, discriminant, and convergent validity. Participants were randomly split into two equal samples, with exploratory factor analysis conducted in the first sample and confirmatory factor analysis in the second. Test-retest reliability was assessed in a subsample of 64 Veterans. The 45-item MISS-M consists of 10 theoretically grounded subscales assessing guilt, shame, moral concerns, religious struggles, loss of religious faith/hope, loss of meaning/purpose, difficulty forgiving, loss of trust, and self-condemnation. The Cronbach's alpha of the overall scale was .92 and of individual subscales ranged from .56 to .91. The test-retest reliability was .91 for the total scale and ranged from .78 to .90 for subscales. Discriminant validity was demonstrated by relatively weak correlations with other psychosocial, religious, and physical health constructs, and convergent validity was indicated by strong correlations with PTSD, depression, and anxiety symptoms. The MISS-M is a reliable and valid multi-dimensional symptom measure of moral injury that can be used in studies targeting MI in Veterans and Active Duty Military with PTSD symptoms and may also be used by clinicians to identify those at risk.

RESUMO

INTRODUCTION: Veterans with mental illness tend to have shorter life spans and suboptimal physical health because of a variety of factors. These factors include poor nutrition, being overweight, and smoking cigarettes. Nonphysical contributors that may affect quality of life are the stigma associated with mental illness, social difficulties, and spiritual crises. Current mental health treatment focuses primarily on the delivery of medication and evidence-based psychotherapies, which may not affect all the above areas of a Veteran's life as they focus primarily on improving psychological symptoms. Clinicians may find greater success using integrative, comprehensive, multifaceted programs to treat these problems spanning the biological, psychological, social, and spiritual domains. These pilot studies test an adjunctive, holistic, behavioral approach to treat mental illness. This pilot work explores the hypotheses that engagement in a greater number of therapeutic lifestyle changes (TLCs) leads to improvement in quality of life, reduction of psychiatric symptoms, and weight loss. MATERIALS AND METHODS: Institutional Review Boards for human subjects at the Veterans Affairs (VA) Greater Los Angeles and Long Beach Healthcare Systems approved pilot study activities at their sites. Pilot Study 1 was a prospective survey study of Veterans with mental illness, who gained weight on an atypical antipsychotic medication regimen, participating in a weight management study. At each session of the 1-year study, researchers asked a convenience sample of 55 Veterans in the treatment arm whether they engaged in each of the eight TLCs: exercise, nutrition/diet, stress management and relaxation, time in nature, relationships, service to others, religious or spiritual involvement, and recreation. Pilot Study 2 applied the TLC behavioral intervention and examined 19 Veterans with mental illness, who attended four classes about TLCs, received individual counseling over 9 weeks, and maintained journals to track TLC practice. Besides weekly journals, researchers also collected prospective data on quality of life, psychiatric symptoms, vitals, and anthropometric measurements. In both studies, investigators tested for main effects of the total number of TLCs practiced and study week using mixed-effects linear models with independent intercepts by participant. RESULTS: In Study 1, engagement in more TLC behaviors was significantly associated with higher ratings of quality of life, as well as greater weight loss for each additional type of TLC practiced. In Study 2, TLC practice increased significantly over 9 weeks, and was significantly associated with improvements in quality of life and diastolic blood pressure. CONCLUSION: Counseling Veterans to practice TLCs provides a holistic adjunct to current treatments for mental illness. TLCs may confer multiple benefits upon Veterans with mental illness, enhancing quality of life and well-being along with weight management efforts. As these were pilot studies, the samples sizes were relatively small and a control group was lacking. Our findings may have broader implications supporting a holistic approach in both primary and mental health care settings. Future research will expand this work to address its weaknesses and examine the cost differential between this holistic approach and traditional mental health treatment.

RESUMO

BACKGROUND: Weight gain and other metabolic sequelae of antipsychotic medications can lead to medication non-adherence, reduced quality of life, increased costs, and premature mortality. Of the approaches to address this, behavioral interventions are less invasive, cost less, and can result in sustained long-term benefits. OBJECTIVE: We investigated behavioral weight management interventions for veterans with mental illness across four medical centers within the Veterans Affairs (VA) Healthcare System. DESIGN: We conducted a 12-month, multi-site extension of our previous randomized, controlled study, comparing treatment and control groups. PARTICIPANTS: Veterans (and some non-veteran women) diagnosed with mental illness, overweight (defined as having a BMI over 25), and required ongoing antipsychotic therapy. INTERVENTIONS: One group received "Lifestyle Balance" (LB; modified from the Diabetes Prevention Program) consisting of classes and individual nutritional counseling with a dietitian. A second group received less intensive "Usual Care" (UC) consisting of weight monitoring and provision of self-help. MAIN MEASURES: Participants completed anthropometric and nutrition assessments weekly for 8 weeks, then monthly. Psychiatric, behavioral, and physical assessments were conducted at baseline and months 2, 6, and 12. Metabolic and lipid laboratory tests were performed quarterly. KEY RESULTS: Participants in both groups lost weight. LB participants had a greater decrease in average waist circumference [F(1,1244) = 11.9, p < 0.001] and percent body fat [F(1,1121) = 4.3, p = 0.038]. Controlling for gender yielded statistically significant changes between groups in BMI [F(1,1246) = 13.9, p < 0.001]. Waist circumference and percent body fat decreased for LB women [F(1,1243) = 22.5, p < 0.001 and F(1,1221) = 4.8, p = 0.029, respectively]. The majority of LB participants kept food and activity journals (92%), and average daily calorie intake decreased from 2055 to 1650 during the study (p < 0.001). CONCLUSIONS: Behavioral interventions specifically designed for individuals with mental illness can be effective for weight loss and improve dietary behaviors. "Lifestyle Balance" integrates well with VA healthcare's patient-centered "Whole Health" approach. ClinicalTrials.gov identifier NCT01052714.

RESUMO

Ancestral stress can program stress sensitivity and health trajectories across multiple generations. While ancestral stress is uncontrollable to the filial generations, it is critical to identify therapies that overcome transgenerational programming. Here we report that prenatal stress in rats generates a transgenerationally heritable endocrine and epigenetic footprint and elevated stress sensitivity which can be alleviated by beneficial experiences in later life. Ancestral stress led to downregulated glucocorticoid receptor and prefrontal cortex neuronal densities along with precocious development of anxiety-like behaviours. Environmental enrichment (EE) during adolescence mitigated endocrine and neuronal markers of stress and improved miR-182 expression linked to brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) regulation in stressed lineages. Thus, EE may serve as a powerful intervention for adverse transgenerational programming through microRNA-mediated regulation of BDNF and NT-3 pathways. The identification of microRNAs that mediate the actions of EE highlights new therapeutic strategies for mental health conditions and psychiatric disease.

RESUMO

BACKGROUND: An adverse fetal environment in utero has been associated with long-term alterations in brain structure and function, and a higher risk of neurological disorders in later life. A common consequence of early adverse experience is impaired motor system function. A causal relationship for stress-associated impairments and a suitable therapy, however, have not been determined yet. OBJECTIVE: To investigate the impact of ancestral stress on corticospinal tract (CST) morphology and fine motor performance in rats, and to determine if adverse programming by ancestral stress can be mitigated by environmental enrichment therapy in rats. METHODS: The study examined F3 offspring generated by three lineages; one with prenatal stress only in the F1 generation, one with compounding effects of multigenerational prenatal stress, and a non-stress control lineage. F3 offspring from each lineage were injected with biotinylated dextran amine (BDA) into the motor cortex for anterograde tracing of the CST. RESULTS: Examination of the CST revealed reduced axonal density in the ancestrally stressed lineages. These anatomical changes were associated with significant impairments in skilled walking, as indicated by reduced foot placement accuracy and disturbed inter-limb coordination. Therapeutic intervention by environmental enrichment reduced the neuromorphological consequences of ancestral stress and restored skilled walking ability. CONCLUSIONS: The data suggest a causal relationship between stress-induced abnormal CST function and loss of fine motor performance. Thus, ancestral stress may be a determinant of motor system development and motor skill. Environmental enrichment may represent an effective intervention for the adverse programming by ancestral stress and trauma.

RESUMO

OBJECTIVE: To demonstrate the effectiveness of a Diabetes Prevention Program-inspired 12-month behavioral intervention for patients with severe mental illness (SMI) and medication-associated obesity. METHOD: This randomized, controlled, parallel, superiority study screened 225 volunteers from November 2005 to August 2008 at the VA Greater Los Angeles Healthcare System. 122 outpatients with DSM-IV-diagnosed SMI taking antipsychotic medications who had ≥ 7% weight gain or body mass index (BMI) > 25 were randomized by computer-generated number to Lifestyle Balance treatment intervention (n = 60) or usual care control (n = 62) groups. Clinical raters were masked to randomization. Treatment intervention included weekly classes and individual counseling for 8 weeks, food and exercise diaries, rewards, caregiver consultations, and monthly booster classes and counseling for 1 year. Controls received self-help materials and visited at equivalent intervals without formal classes or counseling. Outcomes were changes in anthropometric measurements, psychiatric symptoms, health knowledge, and glucose, hemoglobin A1c, and lipid levels. RESULTS: Our intention-to-treat analysis found significant differences in predicted trajectory of mean weight change between the groups over 12 months (P < .01), with treatment participants expected to lose an average 4.6 kg, while control participants would gain an average 0.6 kg. BMI and body fat percentage followed the same pattern. Both groups demonstrated statistically significant improvements in health knowledge quiz scores over time (P = .006), without significant difference between groups. CONCLUSIONS: Treatment was more effective than usual care control in treating medication-associated obesity, independent of SMI diagnosis, antipsychotic medication, and knowledge gained, suggesting that behavioral interventions are effective in SMI patients.

RESUMO

Weight gain and worsening metabolic parameters are often side effects of antipsychotic medications used by individuals with severe mental illness. To address this, a randomized, controlled research study of a behavioral weight management program for individuals with severe mental illness was undertaken to assess its efficacy. Patients unable to meet weight loss goals during the first portion of the year-long study were given the option of using meal replacement shakes in an effort to assist with weight loss. Specific requirements for use of meal replacement shakes were specified in the study protocol; only five patients were able to use the shakes in accordance with the protocol and lose weight while improving metabolic parameters. Case studies of two subjects are presented, illustrating the challenges and obstacles they faced, as well as their successes. Taking responsibility for their own weight loss, remaining motivated through the end of the study, and incorporating the meal replacement shakes into a daily routine were factors found in common with these patients. Use of meal replacements shakes with this population may be effective.

RESUMO

The consumption of artificial food dye (AFD) during childhood and adolescence has been linked to behavioural changes, such as hyperactivity. It is possible that the vulnerability to AFDs is modified by prenatal stress. Common consequences of prenatal stress include hyperactivity, thus potentially leading to synergistic actions with AFDs. Here, we investigated the compounding effect of multigenerational prenatal stress (MPS) and AFD consumption on the development of hyperactivity and anxiety-related behaviours across the lifespan in male rats. MPS treatment involved a family history of four consecutive generations of prenatal stress (F4 generation). AFD treatment included a 4%-concentration of FD&C Red 40, FD&C Yellow 5, FD&C Yellow 6, and FD&C Blue 1 in the drinking water from postnatal days 22 to 50 to resemble juvenile and adolescent dietary exposure. Using several exploration tasks, animals were tested in motor activity and anxiety-like behaviours from adolescence to 13 months of age. MPS resulted in hyperactivity both early (50 days) and later in life (13 months), with normalized activity patterns at reproductive age. AFD consumption resulted in hyperactivity during consumption, which subsided following termination of treatment. Notably, both MPS and AFD promoted risk-taking behaviour in young adults (3 months). There were few synergistic effects between MPS and AFD in this study. The findings suggest that AFDs exert the most noticeable effects at the time of exposure. MPS, however, results in a characteristic lifespan profile of behavioural changes, indicating that development and aging represent particularly vulnerable periods in life during which a family history of prenatal stress may precipitate.

RESUMO

OBJECTIVE: The purpose of this project was to educate inpatients with psychotic disorders, many of whom were taking second-generation antipsychotics, about lifestyle changes they can make to combat weight gain. METHOD: All inpatients on a Veterans Affairs acute inpatient schizophrenia treatment unit were invited to a 30-minute, didactic presentation given by a medical student and a psychology student under the supervision of the primary investigator. The topics covered included the health benefits of maintaining an ideal body weight by selecting foods according to the USDA Food Pyramid, determining adequate food portions, choosing healthy meals outside the home, and beginning and adhering to an exercise program. Subjects completed a 13-item quiz concerning their knowledge of food and nutrition before and after the presentation to determine its efficacy in teaching patients the material. RESULTS: Fifty patients completed both the pre- and post-presentation tests. The mean percentage of correct answers on the pre-test was 85.6%, which rose to 89.3% on the post-test. This difference of 3.7% was statistically significant (t = 2.43, df = 49, p < 0.02), and the mean percent of improvement was 6.1%. CONCLUSIONS: This study demonstrates that psychotic individuals are able to benefit from educational presentations about nutrition and a healthy lifestyle. A statistically significant improvement in test scores suggests that subjects gained an understanding of basic concepts related to food choices and fitness.
