Cognitive determinants of community functioning and quality of life in homeless adults with mental illness: 6-year follow-up from the At Home/Chez Soi Study Toronto site.

BACKGROUND: High rates of physical and mental health comorbidities are associated with functional impairment among persons who are homeless. Cognitive dysfunction is common, but how it contributes to various functional outcomes in this population has not been well investigated. This study examines how cognition covaries with community functioning and subjective quality of life over a 6-year period while accounting for the effects of risk and protective factors. METHODS: Participants were 349 homeless adults (mean age = 39.8) recruited from the Toronto site of the At Home/Chez Soi study, a large Canadian randomized control trial of Housing First. Participants completed up to four clinical evaluations over 6 years. Factor scores were created to index verbal learning and memory (vLM) and processing speed-cognitive flexibility (PSCF). The primary outcomes were community functioning and subjective quality of life. Risk factors included lifetime homelessness, mental health diagnoses, medical comorbidity, and childhood adversity. Linear mixed-effects models were conducted to examine cognition-functional outcome associations over time, with resilience as a moderator. RESULTS: Better vLM (b = 0.787, p = 0.010) and PSCF (b = 1.66, p < 0.001) were associated with better community functioning, but not with quality of life. Resilience conferred a protective effect on subjective quality of life (b = 1.45, p = 0.011) but did not moderate outcomes. CONCLUSIONS: Our findings suggest a need to consider the unique determinants of community functioning and quality of life among homeless adults. Cognition should be prioritized as a key intervention target within existing service delivery models to optimize long-term functional outcomes.

Evaluation of neurological testing for hand-arm vibration syndrome.

BACKGROUND: The neurological component of hand-arm vibration syndrome (HAVS) uses the Stockholm Workshop Scale sensorineural (SWS SN) stages for classification. Proximal compressive neuropathies are common in HAVS and the symptoms are similar to SN HAVS. The SWS may not be a valid staging tool if a patient has comorbid proximal compression neuropathy. AIMS: To evaluate the prevalence of proximal compression neuropathy in patients presenting for HAVS assessment and examine the association between compressive neuropathies and SWS SN. METHODS: A standardized assessment protocol was used to assess 431 patients for HAVS at St. Michael's Hospital, Toronto, Ontario. The prevalence of median and ulnar compressive neuropathies was determined. The association between proximal compression neuropathies and SWS SN stage (0/1 versus 2/3) was evaluated using Chi-square and Fisher's exact tests as well as multivariable logistic regression. RESULTS: Most patients (79%) reported numbness and 20% had reduced sensory perception (SWS SN Stage 2/3). Almost half (45%) had median neuropathy at the wrist and 7% had ulnar neuropathy. There was no association between the SWS SN stage and median or ulnar neuropathy. CONCLUSIONS: Two neurological lesions should be investigated in patients presenting for HAVS assessment: compressive neuropathy and digital neuropathy. The prevalence of compressive neuropathies is high in patients being assessed for HAVS and therefore nerve conduction studies (NCS) should be included in HAVS assessment protocols. Comorbid proximal neuropathy does not affect the SWS SN stage; therefore, NCS and SWS SN seem to be measuring different neurological outcomes in HAVS patients.

NB housing study protocol: investigating the relationship between subsidized housing, mental health, physical health and healthcare use in New Brunswick, Canada.

BACKGROUND: Income and housing are pervasive social determinants of health. Subsidized housing is a prominent affordability mechanism in Canada; however, waitlists are lengthy. Subsidized rents should provide greater access to residual income, which may theoretically improve health outcomes. However, little is known about the health of tenants who wait for and receive subsidized housing. This is especially problematic for New Brunswick, a Canadian province with low population density, whose inhabitants experience income inequality, social exclusion, and challenges with healthcare access.  METHODS: This study will use a longitudinal, prospective matched cohort design. All 4,750 households on New Brunswick's subsidized housing wait list will be approached to participate. The survey measures various demographic, social and health indicators at six-month intervals for up to 18 months as they wait for subsidized housing. Those who receive housing will join an intervention group and receive surveys for an additional 18 months post-move date. With consent, participants will have their data linked to a provincial administrative database of medical records.  DISCUSSION: Knowledge of housing and health is sparse in Canada. This study will provide stakeholders with a wealth of health information on a population that is historically under-researched and underserved.

Evaluation of an occupational medicine patient consultation note assessment tool.

BACKGROUND: Medical education focuses on assessment, diagnosis and management of various clinical entities. The communication of this information, particularly in the written form, is rarely emphasized. Though there have been assessment tools developed to support medical learner improvement in this regard, none are oriented to occupational medicine (OM) practice. AIMS: This study was aimed to develop and evaluate an assessment tool for consultation letters, by modifying a previously validated assessment tool to suit practice in OM. METHODS: Using an iterative process, OM specialists added to the Consultation Letter Rating Scale (CLRS) of the Royal College of Physicians and Surgeons of Canada (henceforth abbreviated as RC) additional questions relevant to communication in the OM context. The tool was then used by two OM specialists to rate 40 anonymized OM clinical consultation letters. Inter-rater agreement was measured by percent agreement, kappa statistic and intraclass correlation. RESULTS: There was generally good percent agreement (>80% for the majority of the RC and OM questions). Intraclass correlation for the five OM questions total scores was slightly higher than the intraclass correlations for the five RC questions (0.59 versus 0.46, respectively), suggesting that our modifications performed at least as well as the original tool. CONCLUSIONS: This new tool designed specifically for evaluation of patient consultation notes in OM provides a good option for medical educators in a variety of practice areas in providing non-summative, low-stakes assessment and/or feedback to nurture increased competency in written communication skills for postgraduate trainees in OM.

Evaluating networked drug checking services in Toronto, Ontario: study protocol and rationale.

BACKGROUND: The increasing incidence of fatal opioid overdose is a public health crisis in Canada. Given growing consensus that this crisis is related to the presence of highly potent opioid adulterants (e.g., fentanyl) in the unregulated drug supply, drug checking services (DCS) have emerged as part of a comprehensive approach to overdose prevention. In Canada's largest city, Toronto, a network of DCS launched in 2019 to prevent overdose and overdose-related risk behaviors. This network employs mass spectrometry technologies, with intake sites co-located with supervised consumption services (SCS) at three frontline harm reduction agencies. The protocol and rationale for assessing the impact of this multi-site DCS network in Toronto is described herein. The aims of this study are to (1) evaluate the impact of DCS access on changes in and factors influencing overdose and related risk behaviors, (2) investigate the perceived capacity of DCS to prevent overdose, and (3) identify composition (qualitative and quantitative) trends in Toronto's unregulated drug supply. METHODS: We will use a parallel-mixed-methods design with complementary data sources (including data from chemical analysis of drug samples, quantitative intake and post-test surveys, SCS, coroners, paramedic services, and qualitative interviews), followed by a meta-inference process wherein results from analyses are synthesized. RESULTS: Whereas most DCS globally target "recreational drug users," in Toronto, this networked DCS will primarily target marginalized people who use drugs accessing frontline services, many of whom use drugs regularly and by injection. This evolution in the application of DCS poses important questions that have not yet been explored, including optimal service delivery models and technologies, as well as unique barriers for this population. Increasing information on the unregulated drug supply may modify the risk environment for this population of people who use drugs. CONCLUSIONS: This study addresses evidence gaps on the emerging continuum of overdose prevention responses and will generate critical evidence on a novel approach to reducing the ongoing high incidence of drug-related morbidity and mortality in Canada and elsewhere.

Using self-reported data on the social determinants of health in primary care to identify cancer screening disparities: opportunities and challenges.

BACKGROUND: Data on the social determinants of health can help primary care practices target improvement efforts, yet relevant data are rarely available. Our family practice located in Toronto, Ontario routinely collects patient-level sociodemographic data via a pilot-tested survey developed by a multi-organizational steering committee. We sought to use these data to assess the relationship between the social determinants and colorectal, cervical and breast cancer screening, and to describe the opportunities and challenges of using data on social determinants from a self-administered patient survey. METHODS: Patients of the family practice eligible for at least one of the three cancer screening types, based on age and screening guidelines as of June 30, 2015 and who had answered at least one question on a socio-demographic survey were included in the study. We linked self-reported data from the sociodemographic survey conducted in the waiting room with patients' electronic medical record data and cancer screening records. We created an individual-level income variable (low-income cut-off) that defined a poverty threshold and took household size into account. The sociodemographic characteristics of patients who were overdue for screening were compared to those who were up-to-date for screening for each cancer type using chi-squared tests. RESULTS: We analysed data for 5766 patients for whom we had survey data. Survey participants had significantly higher screening rates (72.9, 78.7, 74.4% for colorectal, cervical and breast cancer screening respectively) than the 13, 036 patients for whom we did not have survey data (59.2, 65.3, 58.9% respectively). Foreign-born patients were significantly more likely to be up-to-date on colorectal screening than their Canadian-born peers but showed no significant differences in breast or cervical cancer screening. We found a significant association between the low-income cut-off variable and cancer screening; neighbourhood income quintile was not significantly associated with cancer screening. Housing status was also significantly associated with colorectal, cervical and breast cancer screening. There was a large amount of missing data for the low-income cut-off variable, approximately 25% across the three cohorts. CONCLUSION: While we were able to show that neighbourhood income might under-estimate income-related disparities in screening, individual-level income was also the most challenging variable to collect. Future work in this area should target the income disparity in cancer screening and simultaneously explore how best to collect measures of poverty.

Current stress and poor oral health.

BACKGROUND: Psychological stress appears to contribute to poor oral health systemically in combination with other chronic diseases. Few studies directly examine this relationship. METHODS: Data from a cross-sectional study of 2,412 participants between the ages of 25-64 years old living in the City of Toronto between 2009 and 2012 were used to examine the relationship between current stress and two self-rated oral health outcomes (general oral health and oral pain). Dental care utilization and access to dental insurance were examined as effect modifiers. RESULTS: A positive relationship between current stress and poor oral health was observed for both outcomes (oral pain coefficient 0.32, 95 % CI 0.26-0.38; general oral health coefficient 0.28, 95 % CI 0.19-0.36). Effects on oral pain were stronger for the uninsured, while effects on general oral health were stronger with decreasing socioeconomic position. CONCLUSIONS: Our findings suggest that individuals with greater perceived stress also report poorer oral health, and that this relationship is modified by dental insurance and socioeconomic position. These findings warrant a greater focus on the role of psychological stress in the development of oral disease, including how perceived stress contributes to health inequities in self-reported oral health status. Patients experiencing stressful lives may differentially require closer monitoring and more vigilant maintenance of their oral health, above and beyond that which is needed to achieve a state of health in the oral environment of less stressed individuals. There may be health promoting effects of addressing psychosocial concerns related to dental care - particularly for the poor and uninsured.

Human papillomavirus (HPV) vaccine uptake among a community-recruited sample of gay, bisexual, and other men who have sex with men in the three largest cities in Canada from 2017 to 2019.

INTRODUCTION: In 2015/2016, Canada's largest provinces implemented publicly-funded human papillomavirus (HPV) vaccination programs for gay, bisexual, and other men who have sex with men (GBM) ≤ 26 years old. We sought to describe HPV vaccine uptake among GBM and determine barriers and facilitators to vaccine initiation with a focus on healthcare access and utilization. METHODS: Engage is a cohort study among GBM aged 16 + years in three Canadian cities recruited from 2017 to 2019 via respondent driven sampling (RDS). Men completed a comprehensive questionnaire at baseline. By publicly-funded vaccine eligibility (≤26 years old = eligible for vaccination, ≥27 years old = ineligible), we described HPV vaccine uptake (initiation = 1 + dose, completion = 3 doses) and explored factors associated with vaccine initiation using Poisson regression. All analyses were weighted with the RDS-II Volz-Heckathorn estimator. RESULTS: Across the three cities, 26-35% and 14-21% of men ≤ 26 years and 7-26% and 2-9% of men ≥ 27 years initiated and completed HPV vaccination, respectively. Vaccine initiation was significantly associated with STI/HIV testing or visiting a HIV care specialist in the past six months (≤26: prevalence ratio[PR] = 2.15, 95% confidence interval[CI] 1.06-4.36; ≥27: PR = 2.73, 95%CI 1.14-6.51) and past hepatitis A or B vaccination (≤26: PR = 2.88, 95%CI 1.64-5.05; ≥27: PR = 2.03, 95%CI 1.07-3.86). Among men ≥ 27 years old, vaccine initiation was also positively associated with accessing PrEP, living in Vancouver or Toronto, but negatively associated with identifying as Latin American and increasing age. Vaccine initiation was twice as likely among men ≥ 27 years with private insurance versus no insurance. CONCLUSIONS: Sixty-five to 74% of men eligible for publicly-funded vaccine across the three cities remained unvaccinated against HPV by 2019. High vaccine cost may partly explain even lower uptake among men ≥ 27 years old. Men seeking sexual health care were more likely to initiate vaccination; bundling vaccination with these services may help improve HPV vaccine uptake.

Human papillomavirus (HPV) vaccination across a cascade of knowledge, willingness, and uptake among gay, bisexual, and other men who have sex with men in Canada's three largest cities.

BACKGROUND: Some Canadian jurisdictions offer publicly funded HPV vaccine to gay, bisexual, and other men who have sex with men (GBM) aged ≤26 years. We characterized factors associated with being in different stages of HPV vaccination. METHODS: Engage is a sexual health study of GBM in the three largest Canadian cities recruited via respondent driven sampling (RDS). We categorized participants as: (1) unaware of HPV vaccine, (2) undecided/unwilling to get vaccinated, (3) willing to get vaccinated, (4) vaccinated with one or more doses. Our RDS-II weighted analyses used multinomial logistic regression to identify factors associated with being in earlier stages of the cascade compared to Stage 4. RESULTS: Across the cities, 26-40%, 7-14%, 33-39%, and 13-28% were in Stages 1 to 4, respectively. Compared to Stage 4, being in earlier stages of the cascade was associated with bisexual-identification (Stage 1: adjusted odds ratio[aOR] = 2.84, 95% confidence interval[CI] = 1.06-7.62; Stage 2: aOR = 3.09, 95%CI = 1.19-8.05), having immigrated to Canada (Stage 1: aOR = 1.79, 95%CI 1.07-2.99), preference to keep same-sex romantic relationships private (Stage 1: aOR = 1.25, 95% CI = 1.05-1.48; Stage 2: aOR = 1.24, 95%CI = 1.05-1.46), not receiving sexual health information (Stage 1: aOR = 0.31, 95% CI = 0.13-0.71; Stage 2: aOR = 0.27, 95%CI = 0.12-0.64), not accessing a health-care provider (Stage 2: aOR = 0.36, 95%CI = 0.15-0.83), and no past hepatitis A/B vaccination (Stage 1: aOR = 0.16, 95% CI = 0.09-0.30; Stage 2: aOR = 0.18, 95%CI = 0.09-0.35; Stage 3: aOR = 0.38, 95%CI = 0.21-0.61). DISCUSSION: Interventions are needed to reduce social and financial barriers, increase sexual health knowledge, and improve GBM-competent health-care access to increase vaccine uptake among GBM.

Is there a role for physician involvement in introducing research to surrogate decision makers in the intensive care unit? (The Approach trial: a pilot mixed methods study).

PURPOSE: To assess the feasibility of conducting a randomized trial comparing two strategies [physician (MD) vs. non-physician (non-MD)] for approaching substitute decision makers (SDMs) for research and to evaluate SDMs' experiences in being approached for consent. METHODS: A pilot mixed methods study of first encounters with SDMs. RESULTS: Of 137 SDMs (162 eligibility events), 67 and 70 were randomized to MD and non-MD introductions, respectively. Eighty SDMs (98 events) provided consent and 21 SDMs (24 events) declined consent for studies, including 2 SDMs who provided and declined consent. We identified few missed introductions [4/52 (7.7 %)] and protocol violations [6/117 (5.1 %)], high comfort, satisfaction and acceptance scores and similar consent rates in both arms. SDMs provided consent significantly more often when a patient update was provided in the MD arm. Most SDMs (85.7 %) felt that physician involvement was inconsequential and preferred physician time to be dedicated to patient care; however, SDM experiences were closely related to their recall of being approached and recall was poor. SDMs highlighted 7 themes of importance to them in research surrogate decision-making. CONCLUSION: SDMs prioritized the personal attributes of the person approaching them over professional designation and preferred physician time to be dedicated to patient care. A mixed methods design evaluated intervention fidelity and provided the rationale for not proceeding to a larger trial, despite achieving all feasibility metrics in the pilot trial. TRIAL REGISTRATION NUMBER: NCT01232621.

Initial and repeat mammography screening in a low income multi-ethnic population in Los Angeles.

Low income, older, minority women are at high risk for underutilization of screening mammography. One strategy for increasing utilization is to conduct interventions targeting local and state health departments where a majority of these women seek health care. A prerequisite for conducting effective screening programs is to obtain current and accurate information on baseline screening rates to understand the nature and scope of the problem and to plan appropriate intervention strategies. The sample consisted of 3240 women who were 50+ years of age from 2 hospitals and 2 comprehensive health centers operated by the Los Angeles County Department of Health Services. Reviews of medical records indicated that only 21% of the sample had received a mammogram in the 12 months prior to the clinic visit on which they were sampled and 23% of the sample received a mammogram in the following 9 months. Approximately 5% of the total sample received a repeat mammogram in the 21-month period over which they were tracked. Prospective independent predictors of screening were age, number of visits to primary care clinics, number of visits to specialty care clinics, and history of breast abnormalities. The results underscore the importance of implementing programs to increase mammography implementing programs to increase mammography screening within public facilities serving low income multiethnic women. An important finding is that a large number of older women are seen in specialty clinics, which represents an untapped resource for increasing screening in this population. Innovative interventions targeting such specialty clinics could substantially contribute to increasing screening rates. A comprehensive approach targeting system, physician, and patient barriers is recommended.

Reproducibility of alternative probe synthesis approaches for gene expression profiling with arrays.

Before gene expression profiling with microarray technology can be transferred to the diagnostic setting, we must have alternative approaches for synthesizing probe from limited RNA samples, and we must understand the limits of reproducibility in interpreting gene expression results. The current gold standard of probes for use with both microarrays and high-density filter arrays are synthesized from 1 microg of purified poly(A)+ RNA. We evaluated two approaches for synthesizing cDNA probes from total RNA with subsequent hybridization to high-density filter arrays: 1) reverse transcription (RT) of 5 microg total RNA and 2) RT-polymerase chain reaction (RT-PCR) of 1 microg total RNA, using the SMART system. The reproducibility of these two approaches was compared to the current gold standard. All three methods were highly reproducible. Triplicate experiments resulted in the following concordance correlation coefficients to evaluate reproducibility: 0.88 for the gold standard, 0.86 for cDNA probe synthesized by RT from total RNA, and 0.96 for the SMART cDNA probe synthesized from total RNA. We also compared the expression profile of 588 genes for the total RNA methods to that obtained with the gold standard. Of 150 positive genes detected by the gold standard, 97 (65%) were detected by cDNA probe synthesized by RT of total RNA, and 122 (81%) were detected by the SMART cDNA probe. We conclude that SMART cDNA probe produces highly reproducible results and yields gene expression profiles that represent the majority of transcripts detected with the gold standard.

Community physicians' cooperation with a program of in-home comprehensive geriatric assessment.

OBJECTIVES: To study the cooperation of primary care physicians with a community-based prevention and health promotion program for older persons, to study physician factors related to cooperation, and to determine any relationship between physician cooperation and patient adherence to program recommendations and patient satisfaction with health care. DESIGN AND SETTING: A survey administered in subjects' homes and physicians' offices in Santa Monica, California. PARTICIPANTS: Patients (n = 81) were intervention group subjects in a 3-year, randomized, controlled trial of in-home comprehensive geriatric assessment paired with prevention and health promotion. Physicians (n = 50) were selected if they had been contacted at least once by a study nurse practitioner about one of these patients. MEASUREMENTS: Physician cooperation was rated by study nurse practitioners. Physicians were interviewed to identify factors associated with cooperation. Patients' satisfaction with health care and adherence were measured prospectively throughout the 3-year program. MAIN RESULTS: Physicians exhibiting better cooperation had fewer years in practice (P = .03) and were more likely to discuss the program with their patients (P = .005), see benefit for their patients from the program (P = .02), and rate program information as useful (P = .002). Higher physician cooperation did not predict higher patient satisfaction (P = .23) but did predict higher patient adherence to program recommendations (P = .02). CONCLUSIONS: Physicians rated as cooperative were more likely to have a positive appraisal of the program, and their patients had higher adherence to program recommendations. These findings suggest that strategies for increasing primary care physician cooperation might improve effectiveness of similar community-based prevention and health promotion programs.

Fatiguing illness among employees in three large state office buildings, California, 1993: was there an outbreak?

UNLABELLED: The objective was to determine if a cluster of chronic fatigue syndrome (CFS)-like illness had occurred among employees in two large state office buildings in northern California, and to identify risk factors for and features of fatiguing illness in this population. DESIGN: case-control study. POPULATION AND SETTING: Over 3300 current employees in two state office buildings and employees in a comparable "control" building. Information was collected on demographic and occupational variables, the occurrence of fatiguing illness for at least one month in the previous year, and the presence of 36 symptoms. A total of 3312 (82%) of 4035 employees returned questionnaires. Overall, 618 (18.7%) persons reported fatigue lasting at least one month; including 382 (11.5%) with fatigue of at least six months' duration and 75 (2.3%) with symptoms compatible with a CFS-like illness. Independent risk factors for fatigue lasting one month or longer were found to be Native American ethnicity (OR 2.4, CI 1.1,5.3), Hispanic ethnicity (OR 1.7, CI 1.3,2.3), female sex (OR 1.5, CI 1.2,1.9), gross household incomes of less than $50,000 (OR 1.3, CI 1.1,1.6), and less than a college education (OR 1.3, CI 1.1,1.6). Similar risks were observed for persons who reported fatigue lasting six months or longer. Female sex (OR 3.2, CI 1.7, 6.4) was the only independent risk factor found for those persons classified as having a CFS-like illness. Case prevalence rates for all three categories of fatigue, as determined by multivariate analysis, were not significantly different among buildings. Despite finding a substantial number of employees with fatiguing illness in the two state office buildings, the prevalence was not significantly different than that for a comparable control building. Previously unidentified risk factors for fatigue of at least one month and at least six months identified in this population included Hispanic ethnicity, not having completed college, and income below $50,000.

Eating orientation, postcessation weight gain, and continued abstinence among female smokers receiving an unsolicited smoking cessation intervention.

Predictors of weight gain following smoking cessation were assessed among 1,219 female smokers enrolled in a health maintenance organization. Women randomized to the treatment group received a cessation intervention without regard to their interest in quitting smoking. It was hypothesized that cessation would result in subsequent weight gain and postcessation weight gain would be associated with scores on a modified Restraint Scale, the Disinhibition Scale, and a scale assessing tendency to eat during periods of negative affect. Persons who abstained from smoking over the 18-month study gained more weight than did intermittent smokers and continuous smokers, and among 762 women who reported at least 1 on-study attempt to quit smoking, 36% gained weight. Weight gain was associated with disinhibited eating and negative affect eating but not with restrained eating. Weight gain also was associated with continued abstinence from smoking.

Clinical determinants of survival from stage Ib cervical cancer in an inner-city hospital.

This study reviewed a high-risk population of inner-city women with FIGO (International Federation of Gynecologists and Obstetricians) stage Ib cervical cancer diagnosed and treated at a single institution between 1986 and 1993. The patient age at diagnosis averaged 49 years, and most of the patients were black (83%). Squamous carcinomas predominated (75%). Radiotherapy was the most frequent treatment modality (49%), followed by surgery (38%) and combined radiation/surgery (13%). The Kaplan-Meier estimated 4-year survival for all patients completing treatment was 81%. Increased survival was significantly associated with therapy. The Kaplan-Meier estimated survival at 26 months (the time of the last death in radiotherapy patients) was 66% for radiotherapy patients and 100% for those treated with surgery. Radiotherapy patients differed from surgery patients in age, tumor size, and pelvic lymph node status, indicating that treatment selection bias could explain the observed difference in survival. Age, race, histology, and cervical lesion size were not significantly associated with survival.

Targeting adult smokers through a multi-ethnic public school system.

In a unique approach to utilizing an existing intervention, "opportunistic" and targeted school-based strategies were used to enroll 446 adults into a tailored preventive health program featuring a health screening and smoking-cessation intervention. Implemented through a public school district serving a multi-ethnic low-to-middle income urban community, subjects in this randomized trial were interviewed at enrollment and at three-, six-, and 12-month follow-up, and rescreened at 12 months, to assess changes in smoking-related knowledge, attitudes, and practices. Using conservative assumptions, self-reported ever-quit rates and continuous abstinence rates of 57.5% and 2.6%, respectively, were achieved across groups; point-prevalence abstinence rates were 13.2%, 12.9%, and 10.3% at three, six, and 12 months. The study examines issues relevant to smoking status and stages of change in this population. The role of the school in increasing access to needed health programming in underserved communities is explored.

Deployment stressors and a chronic multisymptom illness among Gulf War veterans.

Unusual health problems have been reported by Gulf War (GW) veterans, but no single etiology has been linked to these illnesses. This study was conducted to determine the association between self-reported GW deployment stressors and an illness defined by a combination of fatigue, mood-cognition, and musculoskeletal symptoms. A total of 1002 GW veterans from this cross-sectional survey of four Air Force units completed a self-administered questionnaire that asked about symptoms, demographic and military characteristics, and stressors during deployment. Severe and mild-moderate illness was positively associated with self-reports of pyridostigmine bromide use, insect repellent use and belief in a threat from biological or chemical weapons. Injuries requiring medical attention were only associated with severe illness. These results suggest a link between self-reported chemical, emotional, and physical exposures, and GW veterans' illness. Further research is needed to determine physiological and psychological mechanisms through which such stressors could have contributed to this symptom complex.
