Abstract
Objectives: We report results of a systematic review on the health effects of long-term traffic-related air pollution (TRAP) and diabetes in the adult population. Methods: An expert Panel appointed by the Health Effects Institute conducted this systematic review. We searched the PubMed and LUDOK databases for epidemiological studies from 1980 to July 2019. TRAP was defined based on a comprehensive protocol. Random-effects meta-analyses were performed. Confidence assessments were based on a modified Office for Health Assessment and Translation (OHAT) approach, complemented with a broader narrative synthesis. We extended our interpretation to include evidence published up to May 2022. Results: We considered 21 studies on diabetes. All meta-analytic estimates indicated higher diabetes risks with higher exposure. Exposure to NO2 was associated with higher diabetes prevalence (RR 1.09; 95% CI: 1.02; 1.17 per 10 μg/m3), but less pronounced for diabetes incidence (RR 1.04; 95% CI: 0.96; 1.13 per 10 μg/m3). The overall confidence in the evidence was rated moderate, strengthened by the addition of 5 recently published studies. Conclusion: There was moderate evidence for an association of long-term TRAP exposure with diabetes.

Abstract
BACKGROUND Stroke remains the second cause of death worldwide. The mechanisms underlying the adverse association of exposure to traffic-related air pollution (TRAP) with overall cardiovascular disease may also apply to stroke. Our objective was to systematically evaluate the epidemiological evidence regarding the associations of long-term exposure to TRAP with stroke. METHODS PubMed and LUDOK electronic databases were searched systematically for observational epidemiological studies from 1980 through 2019 on long-term exposure to TRAP and stroke with an update in January 2022. TRAP was defined according to a comprehensive protocol based on pollutant and exposure assessment methods or proximity metrics. Study selection, data extraction, risk of bias (RoB) and confidence assessments were conducted according to standardized protocols. We performed meta-analyses using random effects models; sensitivity analyses were assessed by geographic area, RoB, fatality, traffic specificity and new studies. RESULTS Nineteen studies were included. The meta-analytic relative risks (and 95% confidence intervals) were: 1.03 (0.98-1.09) per 1 μg/m3 EC, 1.09 (0.96-1.23) per 10 μg/m3 PM10, 1.08 (0.89-1.32) per 5 μg/m3 PM2.5, 0.98 (0.92; 1.05) per 10 μg/m3 NO2 and 0.99 (0.94; 1.04) per 20 μg/m3 NOx with little to moderate heterogeneity based on 6, 5, 4, 7 and 8 studies, respectively. The confidence assessments regarding the quality of the body of evidence and separately regarding the presence of an association of TRAP with stroke considering all available evidence were rated low and moderate, respectively. CONCLUSION The available literature provides low to moderate evidence for an association of TRAP with stroke.

Abstract
BackgroundThe novel coronavirus disease 2019 (COVID-19) pandemic has spurred global action. Beginning in March of 2020, the Southern California COVID-19 pandemic response to limit virus transmission was characterized by mandated lockdowns and quarantines, resulting in significant stressors for rheumatology patients and potentially threatening their disease.ObjectivesTo examine factors associated with changes in rheumatoid arthritis (RA) disease activity and flares in the COVID-19 pandemic.MethodsRA patients identified by ICD-9/10 codes and active email addresses within a University of California, Los Angeles (UCLA) Rheumatology database were sent surveys via email in July and November of 2020. The survey was UCLA Institutional Review Board approved and included electronic consent and questions related to: perceptions of disease activity/remission via Routine Assessment of Patient Index Data 3 (RAPID3), flare frequency, RA flare questionnaire (RA-FQ), Perceived Stress Scale (PSS-4), and pandemic impact on stress (i.e. emotional state, apprehension, panic, helplessness, work, home, financial, and social distancing stress). Demographics were extracted from electronic medical records. Results were examined via descriptive analyses, Pearson correlations, and chi-square test for comparisons plus linear stepwise regressions where appropriate to evaluate the relationship between stress measures, RA disease activity, and flare frequency and severity.ResultsAmong 5037 patients surveyed, 361 in July and 4676 in November,1128 (22.4%) responded. The study population demographics were: mean age of 57.5 ± 15.1 years, 79.4% female, racially diverse (69.6% Caucasian, 13.7 % LatinX, 9.5 % Asian, and 4.9% Black), and 62% seropositive (CCP and/or RF). Perceived disease activity and remission remained stable in most patients with 719 reporting no flares, and 409 in current flares at the time of the survey (Table 1). A minority reported perceived increases in disease activity which were associated with multiple aspects of perceived stress. At survey completion, 346 had not experienced flares, 290 had experienced one flare, and 492 had experienced multiple flares. Use of DMARDs was associated with lack of flare versus current flare (77.8% versus 71.6%, p = 0.02). The use of conventional synthetic, biologic, or targeted synthetic DMARDs were not associated with flare while current corticosteroid use was associated with flare (9.3% without flare and 20.8% with flare, p < 0.0001). Current flare was associated with increased PSS-4 scores (odds ratio (OR): 1.17 (95% confidence interval: 1.12 – 1.22, p < 0.0001).

Abstract
This mini-tutorial describes how combining aggregate-level data about the physical, built and social environment can facilitate our understanding of factors shaping the human brain and, in turn, brain health. It provides entry-level information about methods and approaches one can use to uncover how inequalities in the local environment lead to health inequalities in general, and those in brain health in particular. This background knowledge should be helpful to those who are interested in using neuroimaging to investigate how environmental factors shape inter-individual variations in the human brain.

Abstract
OBJECTIVE To evaluate use of a British English version of the validated French FLARE-RA questionnaire among American English speaking patients. In addition, to create a culturally adapted American English (AmE) FLARE-RA questionnaire and to examine its attributes of patient-reported RA flare status. METHODS Using standardized cultural adaptation guidelines, we cognitively debriefed 25 American English speaking rheumatoid arthritis (RA) outpatients and created AmE-FLARE-RA with their input. One hundred three additional RA patients were recruited. Patients completed the Routine Assessment of Patient Index Data 3 (RAPID3), patient global visual analogue scale (VAS), AmE-FLARE-RA, and self-reports of flare. Physician global VAS, physician-assessed flare, swollen and tender joint count (TJC), and clinical disease activity index (CDAI) were documented. AmE-FLARE-RA and disease activity measures were compared between patient-reported and physician-reported flare categories. RESULTS Patients were female (89%), with mean (SD) age 51.1 (± 15.3) years and mean disease duration (SD) 11.9 (± 10.1) years, with 26% in remission/low disease activity. Total AmE-FLARE-RA scores, RAPID3, CDAI, and patient global VAS were significantly higher for both patient-reported flares and physician-reported flares compared with non-flaring patients by self- or physician report (p < 0.05). Total AmE-FLARE-RA scores correlated significantly with RAPID3 (corr = 0.50, p < 0.0001) and with CDAI (corr = 0.45, p < 0.0001). Across "no flares," "one flare," and "several flare" groups, there was a non-significant increase in AmE-FLARE-RA scores (p = 0.07). CONCLUSION The British English FLARE-RA was successfully adapted for AmE-speaking RA patients. AmE-FLARE-RA significantly correlated with RAPID3 and CDAI and distinguished between patient-reported and physician-reported flares, making it useful to detect flares in American RA patients.Key Points• The American English FLARE-RA (AmE-FLARE-RA) questionnaire is the result of cognitive debriefing with American RA patients using the British English version of the validated French FLARE-RA and incorporates patient-recommended language modifications..• Patients self-reporting flares had significantly higher AmE-FLARE-RA scores, compared with those without flares at the time of visit. AmE-FLARE-RA scores correlate with RAPID3 and CDAI.• There was a non-statistically significant trend using the AmE-FLARE-RA scores when examining patients with no flare, one flare, or several flares.• AmE-FLARE-RA total scores are uniformly elevated (~ 6.0 on a 0-10 scale), regardless of discordance between patient and MD assessment of flare at time of visit (~ 30%).

Abstract
Aeroallergens occur naturally in the environment and are widely dispersed across Canada, yet their public health implications are not well-understood. This review intends to provide a scientific and public health-oriented perspective on aeroallergens in Canada: their distribution, health impacts, and new developments including the effects of climate change and the potential role of aeroallergens in the development of allergies and asthma. The review also describes anthropogenic effects on plant distribution and diversity, and how aeroallergens interact with other environmental elements, such as air pollution and weather events. Increased understanding of the relationships between aeroallergens and health will enhance our ability to provide accurate information, improve preventive measures and provide timely treatments for affected populations.

Abstract
A desalination plant is proposed to be the major water supply to the Olympic Dam Expansion Mining project. Located in the Upper Spencer Gulf, South Australia, the site was chosen due to the existence of strong currents and their likely advantages in terms of mixing and dilution of discharged return water. A high-resolution hydrodynamic model (Estuary, Lake and Coastal Ocean Model, ELCOM) was constructed and, through a rigorous review process, was shown to reproduce the intricate details of the Spencer Gulf dynamics, including those characterising the discharge site. Notwithstanding this, it was found that deploying typically adopted 'direct insertion' techniques to simulate the brine discharge within the hydrodynamic model was problematic. Specifically, it was found that in this study the direct insertion technique delivered highly conservative brine dilution predictions in and around the proposed site, and that these were grid and time-step dependent. To improve the predictive capability, a strategy to link validated computational fluid dynamics (CFD) predictions to hydrodynamic simulations was devised. In this strategy, environmental conditions from ELCOM were used to produce boundary conditions for execution of a suite of CFD simulations. In turn, the CFD simulations provided the brine dilutions and flow rates to be applied in ELCOM. In order to conserve mass in a system-wide sense, artificial salt sinks were introduced to the ELCOM model such that salt quantities were conserved. As a result of this process, ELCOM predictions were naturally very similar to CFD predictions near the diffuser, whilst at the same time they produced an area of influence (further afield) comparable to direct insertion methods. It was concluded that the linkage of the models, in comparison to direct insertion methods, constituted a more realistic and defensible alternative to predict the far-field dispersion of outfall discharges, particularly with regards to the estimation of brine dilution in the immediate vicinity of an outfall location.

Abstract
BACKGROUND Few epidemiological studies of air pollution have used residential histories to develop long-term retrospective exposure estimates for multiple ambient air pollutants and vehicle and industrial emissions. We present such an exposure assessment for a Canadian population-based lung cancer case-control study of 8353 individuals using self-reported residential histories from 1975 to 1994. We also examine the implications of disregarding and/or improperly accounting for residential mobility in long-term exposure assessments. METHODS National spatial surfaces of ambient air pollution were compiled from recent satellite-based estimates (for PM2.5 and NO2) and a chemical transport model (for O3). The surfaces were adjusted with historical annual air pollution monitoring data, using either spatiotemporal interpolation or linear regression. Model evaluation was conducted using an independent ten percent subset of monitoring data per year. Proximity to major roads, incorporating a temporal weighting factor based on Canadian mobile-source emission estimates, was used to estimate exposure to vehicle emissions. A comprehensive inventory of geocoded industries was used to estimate proximity to major and minor industrial emissions. RESULTS Calibration of the national PM2.5 surface using annual spatiotemporal interpolation predicted historical PM2.5 measurement data best (R2 = 0.51), while linear regression incorporating the national surfaces, a time-trend and population density best predicted historical concentrations of NO2 (R2 = 0.38) and O3 (R2 = 0.56). Applying the models to study participants residential histories between 1975 and 1994 resulted in mean PM2.5, NO2 and O3 exposures of 11.3 μg/m3 (SD = 2.6), 17.7 ppb (4.1), and 26.4 ppb (3.4) respectively. On average, individuals lived within 300 m of a highway for 2.9 years (15% of exposure-years) and within 3 km of a major industrial emitter for 6.4 years (32% of exposure-years). Approximately 50% of individuals were classified into a different PM2.5, NO2 and O3 exposure quintile when using study entry postal codes and spatial pollution surfaces, in comparison to exposures derived from residential histories and spatiotemporal air pollution models. Recall bias was also present for self-reported residential histories prior to 1975, with cases recalling older residences more often than controls. CONCLUSIONS We demonstrate a flexible exposure assessment approach for estimating historical air pollution concentrations over large geographical areas and time-periods. In addition, we highlight the importance of including residential histories in long-term exposure assessments. For submission to: Environmental Health.

Abstract
BACKGROUND Countries worldwide are expending significant resources to improve air quality partly to improve the health of their citizens. Are these societal expenditures improving public health? OBJECTIVES We consider these issues by tracking the risk of death associated with outdoor air pollution over both space and time in Canadian cities. MATERIALS AND METHODS We propose two multi-year estimators that use current plus several previous years of data to estimate current year risk. The estimators are derived from sequential time series analyses using moving time windows. To evaluate the statistical properties of the proposed methods, a simulation study with three scenarios of changing risk was conducted based on 12 Canadian cities from 1981 to 2000. Then an optimal estimator was applied to 24 of Canada's largest cities over the 17-year period from 1984 to 2000. RESULTS The annual average daily concentrations of ozone appeared to be increasing over the time period, whereas those of nitrogen dioxide were decreasing. However, the proposed method returns different time trends in public health risks. Evidence for some monotonic increasing trends in the annual risks is weak for O(3) (p = 0.3870) but somewhat stronger for NO(2) (p = 0.1082). In particular, an increasing time trend becomes apparent when excluding year 1998, which reveals lower risk than proximal years, even though concentrations of NO(2) were decreasing. The simulation results validate our two proposed methods, producing estimates close to the preassigned values. CONCLUSIONS Despite decreasing ambient concentrations, public health risks related to NO(2) appear to be increasing. Further investigations are necessary to understand why the concentrations and adverse effects of NO(2) show opposite time trends.

Abstract
Examining the validity of exposure metrics used in air pollution epidemiologic models has been a key focus of recent exposure assessment studies. The objective of this work has been, largely, to determine what a given exposure metric represents and to quantify and reduce any potential errors resulting from using these metrics in lieu of true exposure measurements. The current manuscript summarizes the presentations of the co-authors from a recent EPA workshop, held in December 2006, dealing with the role and contributions of exposure assessment in addressing these issues. Results are presented from US and Canadian exposure and pollutant measurement studies as well as theoretical simulations to investigate what both particulate and gaseous pollutant concentrations represent and the potential errors resulting from their use in air pollution epidemiologic studies. Quantifying the association between ambient pollutant concentrations and corresponding personal exposures has led to the concept of defining attenuation factors, or alpha. Specifically, characterizing pollutant-specific estimates for alpha was shown to be useful in developing regression calibration methods involving PM epidemiologic risk estimates. For some gaseous pollutants such as NO2 and SO2, the associations between ambient concentrations and personal exposures were shown to be complex and still poorly understood. Results from recent panel studies suggest that ambient NO2 measurements may, in some locations, be serving as surrogates to traffic pollutants, including traffic-related PM2.5, hopanes, steranes, and oxidized nitrogen compounds (rather than NO2).

Abstract
This retrospective observational study was designed to study the impact of a dedicated antenatal clinic service on obstetric and neonatal outcomes among teenage mothers in the maternity unit of a district general hospital in the UK. Outcomes were measured to investigate improvement in obstetric and neonatal outcomes before, and 12 months after the establishment of dedicated clinic for teenage pregnant women. Significant improvement in the birth weight was observed p = 0.01. A modest decrease in neonatal admission to special care unit by 6% was observed. Rate of spontaneous vaginal deliveries increased p = 0.0009. There was significant uptake of contraception and continuation of breast-feeding in this group of young women (p < 0.0001).

Abstract
STUDY OBJECTIVE To assess the short term association between air pollution and mortality in different zones of an industrial city. An intra-urban study design is used to test the hypothesis that socioeconomic characteristics modify the acute health effects of ambient air pollution exposure. DESIGN The City of Hamilton, Canada, was divided into five zones based on proximity to fixed site air pollution monitors. Within each zone, daily counts of non-trauma mortality and air pollution estimates were combined. Generalised linear models (GLMs) were used to test mortality associations with sulphur dioxide (SO(2)) and with particulate air pollution measured by the coefficient of haze (CoH). MAIN RESULTS Increased mortality was associated with air pollution exposure in a citywide model and in intra-urban zones with lower socioeconomic characteristics. Low educational attainment and high manufacturing employment in the zones significantly and positively modified the acute mortality effects of air pollution exposure. DISCUSSION Three possible explanations are proposed for the observed effect modification by education and manufacturing: (1) those in manufacturing receive higher workplace exposures that combine with ambient exposures to produce larger health effects; (2) persons with lower education are less mobile and experience less exposure measurement error, which reduces bias toward the null; or (3) manufacturing and education proxy for many social variables representing material deprivation, and poor material conditions increase susceptibility to health risks from air pollution.

Abstract
Chromosome 6 is a metacentric chromosome that constitutes about 6% of the human genome. The finished sequence comprises 166,880,988 base pairs, representing the largest chromosome sequenced so far. The entire sequence has been subjected to high-quality manual annotation, resulting in the evidence-supported identification of 1,557 genes and 633 pseudogenes. Here we report that at least 96% of the protein-coding genes have been identified, as assessed by multi-species comparative sequence analysis, and provide evidence for the presence of further, otherwise unsupported exons/genes. Among these are genes directly implicated in cancer, schizophrenia, autoimmunity and many other diseases. Chromosome 6 harbours the largest transfer RNA gene cluster in the genome; we show that this cluster co-localizes with a region of high transcriptional activity. Within the essential immune loci of the major histocompatibility complex, we find HLA-B to be the most polymorphic gene on chromosome 6 and in the human genome.

Abstract
We evaluated the relationship between daily levels of particulate and gaseous phase pollutants and mortality within a dynamic cohort of approximately 550,000 individuals whose vital status was ascertained between 1986 and 1999. Time-series methods were applied to evaluate whether there were differential pollutant effects on daily aggregated numbers of deaths in the cohort that was stratified into quintiles of income as defined by the 1991 and 1996 Canadian censuses. The percent change in all-cause, cardiovascular, respiratory, and cancer daily mortality was calculated in relation to short-term changes in levels of a number of particulate (PM(2.5), PM(10-2.5), total suspended particle co-efficient of haze PM(10), SO(4)) and gaseous (O(3), CO, SO(2), NO(2)) pollutants. The estimated effects of air pollution on mortality were adjusted for day of week effects, and several meteorologic variables including temperature, change in barometric pressure, and relative humidity. Several gaseous pollutants were associated with an increased risk of mortality. Specifically for an increase equivalent to the difference between the 90th and 10th percentiles, the estimated percent change in daily mortality based on the 3-day average of NO(2), and SO(2) was 4.0% and 1.3%, respectively. The corresponding changes in mortality associated with SO(2) were much higher when analyses were restricted to death from respiratory disease. Specifically, a difference between the 90th and 10th percentiles was associated with a 5.6% (95% CI= -0.7% to 12.3%). The daily mean coarse fraction (PM(10-2.5)) was associated with increased cardiovascular mortality (estimated change=5.9%, 95% CI=1.1-10.8%). PM(2.5) was not found to be an important predictor of mortality. For NO(2), CO, and SO(2), there was some suggestion of increased risk of all-cause and cardiovascular mortality at lower levels of socioeconomic status. However, these results should be interpreted cautiously due to the small number of deaths observed within each stratum of socioeconomic status.

Abstract
Although some consensus has emerged among the scientific and regulatory communities that the urban ambient atmospheric mix of combustion related pollutants is a determinant of population health, the relative toxicity of the chemical and physical components of this complex mixture remains unclear. Daily mortality rates and concurrent data on size-fractionated particulate mass and gaseous pollutants were obtained in eight of Canada's largest cities from 1986 to 1996 inclusive in order to examine the relative toxicity of the components of the mixture of ambient air pollutants to which Canadians are exposed. Positive and statistically significant associations were observed between daily variations in both gas- and particulate-phase pollution and daily fluctuations in mortality rates. The association between air pollution and mortality could not be explained by temporal variation in either mortality rates or weather factors. Fine particulate mass (less than 2.5 microns in average aerometric diameter) was a stronger predictor of mortality than coarse mass (between 2.5 and 10 microns). Size-fractionated particulate mass explained 28% of the total health effect of the mixture, with the remaining effects accounted for by the gases. Forty-seven elemental concentrations were obtained for the fine and coarse fraction using nondestructive x-ray fluorescence techniques. Sulfate concentrations were obtained by ion chromatography. Sulfate ion, iron, nickel, and zinc from the fine fraction were most strongly associated with mortality. The total effect of these four components was greater than that for fine mass alone, suggesting that the characteristics of the complex chemical mixture in the fine fraction may be a better predictor of mortality than mass alone. However, the variation in the effects of the constituents of the fine fraction between cities was greater than the variation in the mass effect, implying that there are additional toxic components of fine particulate matter not examined in this study whose concentrations and effects vary between locations. One of these components, carbon, represents half the mass of fine particulate matter. We recommend that measurements of elemental and organic carbon be undertaken in Canadian urban environments to examine their potential effects on human health.

Abstract
BACKGROUND Recent studies raise questions on the relationship between adolescent fears and risk for major depression. METHODS An epidemiologic sample of 776 young people received psychiatric assessments in 1983, 1985-1986, and 1992. Prospective associations were examined between fears in adolescence and future episodes of major depression. RESULTS Both overall level of fears and specific fear of dark in adolescence predicted future risk for major depression. CONCLUSIONS Relatively high levels of fear in adolescence represent a risk factor for later episodes of major depression.

Abstract
The authors investigated the association between daily variations in ozone and cause-specific mortality. Fixed-site air pollution monitors in Montreal, Quebec, provided daily mean levels of ozone, particles, and other gaseous pollutants. Information on the date and underlying cause of death was obtained for residents of Montreal who died in the city between 1984 and 1993. The authors regressed the logarithm of daily counts of cause-specific mortality on mean levels of ozone, after accounting for seasonal and subseasonal fluctuations in the mortality time series, non-Poisson dispersion, and weather variables. The effect of ozone on mortality was generally higher in the warm season and among persons aged 65 years or over. For an increase in the 3-day running mean concentration of ozone of 21.3 microg/m(3), the percentage of increase in daily deaths in the warm season was the following: nonaccidental deaths, 3.3% (95% confidence interval (CI): 1.7, 5.0); cancer, 3.9% (95% CI: 1.0, 6.91); cardiovascular diseases, 2.5% (95% CI: 0.2, 5.0); and respiratory diseases, 6.6% (95% CI: 1.8, 11.8). These results were independent of the effects of other pollutants and were consistent with a log-linear response function.

Abstract
This study was undertaken to identify subgroups of the population susceptible to the effects of ambient air particles. Fixed-site air pollution monitors in Montreal, Quebec, Canada, provided daily mean levels of various measures of particulates and gaseous pollutants. Total sulfates were also measured daily (1986-1993) at a monitoring station 150 km southeast of the city (Sutton, Quebec, Canada). We used coefficient of haze (COH), extinction coefficient, and Sutton sulfates to predict fine particles and sulfates from a fine particles model for days that were missing. We used the universal Quebec medicare system to obtain billings and prescriptions for each Montreal resident who died in the city from 1984 to 1993. These data were then used to define cardiovascular and respiratory conditions that subjects had before death. Using standard Poisson regression time-series analyses, we estimated the association between daily nonaccidental mortality and daily concentrations of particles in the ambient air among persons with cardiovascular and respiratory conditions diagnosed before death. We found no persuasive evidence that daily mortality increased when ambient air particles were elevated for subgroups of persons with chronic upper respiratory diseases, airways disease, cerebrovascular diseases, acute coronary artery disease, and hypertension. However, we found that daily mortality increased linearly as concentrations of particles increased for persons who had acute lower respiratory diseases, chronic coronary artery diseases (especially in the elderly), and congestive heart failure. For this latter set of conditions, the mean percent increase in daily mortality (MPC) for an increase in the COH across its interquartile range (18.5 COH units per 327.8 linear meters), averaged over the day of death and the 2 preceding days, was MPC = 5.09% [95% confidence interval (CI) 2.47-7.79%], MPC = 2.62 (95% CI 0.53-4.75%), and MPC = 4.99 (95% CI 2.44-7.60%), respectively. Adjustments for gaseous pollutants generally attenuated these associations, although the general pattern of increased daily mortality remained. In addition, there appeared to be a stronger association in the summer season. The positive associations found for persons who had acute lower respiratory diseases and congestive heart failure are consistent with some prevailing hypotheses and may also be consistent with recent toxicologic data implicating endothelins. Further epidemiologic studies are required to confirm these findings.

Abstract
This study was undertaken to determine whether variations in concentrations of particles in the ambient air of Montreal, Quebec, during the period 1984 to 1993, were associated with daily variations in nonaccidental mortality. Fixed-site air pollution monitors in Montreal provided daily mean levels of various measures of particulates and gaseous pollutants. Total sulfates were also measured daily (1986-1993) at a monitoring station 150 km southeast of the city (Sutton, Quebec). We estimated associations for PM(2.5), PM(10), total suspended particles, coefficient of haze (COH), extinction coefficient, and sulfates. We used coefficient of haze, extinction coefficient, and Sutton sulfates to predict fine particles and sulfates for days that were missing. To estimate the associations between nonaccidental mortality and ambient air particles, we regressed the logarithm of daily counts of nonaccidental mortality on the daily mean levels for the above measures of particulates, after accounting for seasonal and subseasonal fluctuations in the mortality time series, non-Poisson dispersion, weather variables, and gaseous pollutants. There were 140,939 residents of Montreal who died during the study period. We found evidence of associations between daily nonaccidental deaths and most measures of particulate air pollution. For example, the mean percentage increase (MPC) for an increase of total suspended particles of 28.57 microg/m(3) (interquartile range, IQ), evaluated at lag 0 days, was 1.86% (95% confidence interval (CI): 0.00-3.76%), and for an increase of coefficient of haze (IQ=18.5 COH units per 327.8 linear m) the MPC was 1.44% (95% CI: 0.75-2.14%). These results are similar to findings from other studies (the mean percentage increase in nonaccidental deaths for a 100 microg/m(3) increase in daily total suspended particles was 6.7%). We also found increases for fine particles and for inhalable particles, but the confidence intervals included unity. All measures of sulfates showed increased daily mortality; e.g., the MPC for sulfates from fine particles (IQ=3.51 microg/m(3)) was 1.86% (95% CI: 0.40-3.35%). We generally found higher excesses in daily mortality for persons 65 years of age and for exposures averaged across lags 0, 1, and 2 days. The slope of the association between daily mortality and ambient air particles in Montreal, which has lower levels of pollution than most major urban centers, is similar to that reported in most other industrialized cities. This study therefore provides further evidence that the association is linear and that any threshold effect, should it exist, would be found at lower levels of air pollution than those found in Montreal.

Abstract
This study was undertaken to determine whether variations in concentrations of particulates in the ambient air of Montreal, Quebec, during the period 1984 to 1993, were associated with daily variations in cause-specific daily mortality. Fixed-site air pollution monitors in Montreal provided daily mean levels of various measures of particles and gaseous pollutants. Total sulfate was also measured daily (1986-1993) at a monitoring station 150 km southeast of the city (Sutton, Quebec). We used coefficient of haze (COH), extinction coefficient, and sulfate from the Sutton station to predict fine particles and sulfate from fine particles for days that were missing. We estimated associations between cause-specific mortality and PM(2.5), PM(10), predicted fine particles and fine sulfate particles, total suspended particles, coefficient of haze, extinction coefficient, and total sulfate measured at the Sutton station. We selected a set of underlying causes of death, as recorded on the death certificates, as the endpoint and then regressed the logarithm of daily counts of cause-specific mortality on the daily mean levels for the above measures of particulates, after accounting for seasonal and subseasonal fluctuations in the mortality time series, non-Poisson dispersion, weather variables, and gaseous pollutants. We found positive and statistically significant associations between the daily measures of ambient particle mass and sulfate mass and the deaths from respiratory diseases and diabetes. The mean percentage change in daily mortality (MPC), evaluated at the interquartile range for pollutants averaged over the day of death and the preceding 2 days, for deaths from respiratory diseases was MPC(COH)=6.90% (95% CI: 3.69-10.21%), MPC(Predicted PM2.5)= 9.03% (95% CI: 5.83- 12.33%), and MPC(Sutton sulfate)=4.64% (95% CI: 2.46-6.86%). For diabetes, the corresponding estimates were MPC(COH)=7.50% (95% CI: 1.96-13.34%), MPC(Predicted PM2.5)=7.59% (95% CI: 2.36-13.09%), and MPC(Sutton sulfate)=4.48% (95% CI: 1.08-7.99%). Among individuals older than 65 years at time of death, we found consistent associations across our metrics of particles for neoplasms and coronary artery diseases. Associations with sulfate mass were also found among elderly persons who died of cardiovascular diseases and of lung cancer. These associations were consistent with linear relationships. The associations found for respiratory diseases and for cardiovascular diseases, especially in the elderly, are in line with some of the current hypotheses regarding mechanisms by which ambient particles may increase daily mortality. The positive associations found for cancer and for diabetes may be understood through a general hypothesis proposed by Frank and Tankersley, who suggested that persons in failing health may be at higher risk for external insults through the failure of regulating physiological set points. The association with diabetes may be interpreted in light of recent toxicological findings that inhalation of urban particles in animals increases blood pressure and plasmatic levels of endothelins that enhance vasoconstriction and alter electrophysiology. Further research to confirm these findings and to determine whether they are causal is warranted.

Abstract
OBJECTIVE The authors' goal was to examine the relationship between subclinical depressive symptoms in adolescence and major depressive episodes in adulthood. METHOD An epidemiologic sample of 776 young people received psychiatric assessments in 1983, 1985, and 1992. Among adolescents not meeting criteria for major depression, the authors estimated the magnitude of the association between subclinical adolescent depressive symptoms and adult major depression. RESULTS Symptoms of major depression in adolescence strongly predicted an adult episode of major depression: having depressive symptoms more than two-standard-deviations above the mean in number predicted a two-fold to three-fold greater risk for an adult major depressive episode. CONCLUSIONS Symptoms of depression in adolescence strongly predict an episode of major depression in adulthood, even among adolescents without major depression.

Abstract
The association between somatic illness and psychiatric illness is well established in adults but is less clear in childhood and adolescence. A cohort of over 700 randomly selected children in Upstate New York were studied from ages 1-10 years in 1975 to young adulthood in 1992. Psychiatric and physical health were assessed by means of follow-up youth and parent interviews at 8-, 2 1/2-, and 6-year intervals (in 1983, 1985-1986, and 1991-1993). Cross-sectional and longitudinal analyses investigated: 1) the consistency of the relation between physical illness and mental illness in childhood; 2) the specificity of major depressive disorder (MDD) in accounting for the relation; 3) the specificity of immunologically mediated medical disorders in this relation; and 4) whether this relation was attributable to risks associated with low socioeconomic status. Cross-sectionally, ill health was associated with increased risk of psychiatric disorders at all ages, with significant odds ratios (ORs) ranging from 1.76 to 3.26. In prospective analyses, ill health increased the risk of new-onset MDD at all ages (ORs = 2.05-4.48). MDD also predicted subsequent ill health, independent of prior health problems (ORs = 3.81 and 4.04). Relations were not attributable to familial socioeconomic status. Associations were particularly strong between MDD and medical disorders associated with alterations in immunologic factors (ORs = 1.83-6.41). Theories of common immune-mediated vulnerabilities to medical illness and depression are consistent with these associations.

Abstract
BACKGROUND Various studies find relationships among anxiety and depressive disorders of adolescence and adulthood. This study prospectively examines the magnitude of longitudinal associations between adolescent and adult anxiety or depressive disorders. METHODS An epidemiologically selected sample of 776 young people living in upstate New York received DSM-based psychiatric assessments in 1983, 1985, and 1992 using structured interviews. The magnitude of the association between adolescent and adult anxiety or depressive disorders was quantified using odds ratios generated from logistic regression analyses and from a set of latent Markov analyses. We focus on longitudinal associations among narrowly defined DSM anxiety or depressive disorders. RESULTS In simple logistic models, adolescent anxiety or depressive disorders predicted an approximate 2- to 3-fold increased risk for adulthood anxiety or depressive disorders. There was evidence of specificity in the course of simple and social phobia but less specificity in the course of other disorders. Results from the analyses using latent variables suggested that while most adolescent disorders were no longer present in young adulthood, most adult disorders were preceded by adolescent disorders. CONCLUSIONS An anxiety or depressive disorder during adolescence confers a strong risk for recurrent anxiety or depressive disorders during early adulthood. Most anxiety and depressive disorders in young adults may be preceded by anxiety or depression in adolescence.

Abstract
OBJECTIVES This study examined the longitudinal relationship between psychopathology and obesity in young adulthood. METHODS More than 700 youth in a population-based sample were psychiatrically assessed in 1983 (mean age = 14 years) and 1992 (mean age = 22 years). Self-reported body mass index (BMI) in 1992 was regressed on measures of depression and conduct disorder as well as a set of covariates including indices of physical health, social class, intelligence, and cigarette and alcohol use. Associations were examined with BMI treated as a continuous variable and with a binary index of obesity derived from the BMI distribution in each gender. RESULTS BMI in young adults was positively related to a number of covariates. With all covariates controlled, BMI was inversely related to adult depressive symptoms in males but not females. BMI was positively related to adolescent symptoms of conduct disorder in both sexes. Similar associations were found between psychiatric symptoms and obesity. CONCLUSIONS Conduct disorder symptoms in adolescence predicted BMI and obesity in early adulthood. These associations remained after controlling for factors that can affect the association between psychopathology and obesity.

Abstract
Retrospective epidemiologic research in adults suggests that a long-term association between major depression and headache arises during childhood or adolescence. This study uses data from a prospective epidemiologic study to examine the association between major depression and headache from late childhood into early adulthood. An epidemiologically selected sample of 776 youth, aged 9-18, was assessed psychiatrically in 1983 using DISC interviews with both youth and parent informants. Reassessments were conducted in 1985-1986 and 1992. Current and past histories of functionally impairing migraine or chronic headache were elicited in both 1985-1986 and 1992. Regression analyses examined the relationships between major depression and headache status. The prevalence of current functionally impairing headache was approximately 10% in both 1985-1986 and 1992. There were lifetime and cross-sectional associations between headache and major depression. Headache was approximately twice as common in depressed adolescents compared with nondepressed adolescents. Major depression in adolescents, without current or past headache, prospectively predicted the new onset of headaches in young adulthood. Among adolescents who had no history of chronic impairing headache in 1985-1986, those with current major depression faced a nearly tenfold increased risk of developing such headaches at some time during the next 7 years. Consistent with findings of retrospective studies among adults, a longitudinal/ developmental relationship between major depression and functionally impairing headache was found in this prospective epidemiologic study of youth. These findings suggest that (1) neurochemical and pharmacologic commonalities between depression and headache should receive further investigation and that (2) it may be clinically useful to inquire about family history of headache syndromes in adolescents with major depression because such questioning may provide insight about the risk of subsequent functionally impairing headache in a depressed adolescent.

Abstract
Several demographic and post-immigration factors related to self-reported symptoms of anxiety and depression of immigrants in New Zealand were examined in a study involving a sample of 129 Southeast Asian refugees, 57 Pacific Island immigrants, and 63 British immigrants to New Zealand. A questionnaire and the Hopkins Symptom Checklist-25 (HSCL-25) in English and in three Southeast Asian translations were administered, followed by an interview in English or with an interpreter. The findings suggest that demographic characteristics are not associated with symptom level. Post-immigration factors, such as experiencing discrimination in New Zealand, not having close friends, being unemployed, and spending most of one's time with one's own ethnic group affected anxiety and depression scores.

Abstract
OBJECTIVE To test the hypothesis that anxiety and depression in youth, as in adults, become increasingly discriminable when youth meet criteria for an emotional disorder. METHOD The study uses cross-sectional data at two points in time from a large (n = 776) community sample of youths, aged eight to twenty. Associations between major depression and five anxiety disorders (overanxious, obsessive compulsive and separation anxiety disorders, and social and simple phobias) are examined by symptom scale and diagnosis. RESULTS Anxiety and depression are moderately correlated, and substantially comorbid by diagnostic category. Symptoms are more discriminable among youths with diagnoses of at least one emotional disorder than among those without. A single factor accounts for symptoms among the non-diagnosed but multiple factors are required for the diagnosed group. CONCLUSIONS Anxiety and depression are discriminable among youth who meet criteria for a specific emotional disorder but more highly associated among youths without such a diagnosis. This suggests that in youth, as has been shown in adults, depression and anxiety become increasingly discriminable as emotional psychopathology becomes more severe.

Abstract
OBJECTIVE Adults with emotional disorders exhibit abnormalities in growth hormone secretion. If these abnormalities were to occur during childhood, they could affect growth. The purpose of this study was to examine the relationship between youth emotional disorders and stature in early adulthood. METHODS Using data from a prospective epidemiologic study of youth psychopathologic status, we used linear regression to examine the prospective relationship between anxiety disorders (separation anxiety and over-anxious disorders) or major depressive disorder in youth and stature in early adulthood. RESULTS Anxiety disorders during childhood prospectively predicted relatively short stature in early adulthood among females, accounting for more than 5% of the variance in adult height. However, these associations were not found among males. CONCLUSIONS There may be an association between abnormalities in growth and emotional problems in youth. Further research should examine biological measures related to growth among youth with emotional disorders.

Abstract
Sluzki's 1986 mental health model of the migratory process was tested with migrants (both refugees and immigrants), to New Zealand. Its central feature, suggesting an initial symptom free and euphoric phase after arrival in the country of settlement, followed by a crisis stage, was examined for 129 Southeast Asian refugees, 57 Pacific Island immigrants and 63 British immigrants. A questionnaire and the Hopkins Symptom Checklist-25, in English and in three Southeast Asian language translations, were administered face-to-face. All respondents had arrived in New Zealand within the last 15 years. The findings did not support Sluzki's model. Refugees and immigrants in the group with less than six months of residence were not symptom free. Neither did the group with six months to six years residence demonstrate a deterioration in mental health. However, mean depression levels were slightly lower for those who had lived in New Zealand for over six years, suggesting that mental health may improve the longer both refugees and immigrants reside in the host country.

Abstract
BACKGROUND A large cross-sectional study provided an opportunity to estimate the prevalence of childhood asthma in several regions across Canada. METHODS In 1988, approximately 18,000 questionnaires were distributed to the families of 5-8 year old children in 30 communities from the following six regions across Canada: the interior of British Columbia, southeastern Saskatchewan, southwestern Ontario, the central region of Ontario, southern Quebec, and the Maritimes (Nova Scotia and Prince Edward Island). These communities were free of point-source air pollutants and selected to represent a range of ambient sulphate concentrations. In all 14,948 questionnaires were returned representing an 83% response rate. RESULTS Currently present, physician-diagnosed asthma was reported for 4.7% of children by their parents. Persistent wheezing was reported for 13% and persistent cough for 5.9%. Asthma was most common in the two Maritime provinces (7.4%), and least common in British Columbia (3.3%) and Quebec (3.4%). Similar regional differences were seen for persistent cough, persistent wheeze, and also hospital separation rates for asthma which were approximately 800 per 100,000 for the Maritimes and 396 per 100,000 for British Columbia. Differences persisted despite adjustments for several host and environmental (indoor and outdoor) characteristics. CONCLUSIONS The east coast of Canada may be an endemic area of asthma in Canada. If confirmed by objective measures of asthma, a detailed aetiologic investigation could enhance understanding of this phenomenon and the major environmental determinants of asthma morbidity in general.

Abstract
To investigate the acute respiratory health effects of ambient air pollution, the number of emergency of urgent daily respiratory admissions to 168 acute care hospitals in Ontario were related to estimates of exposure to ozone and sulfates in the vicinity of each hospital. Ozone levels were obtained from 22 monitoring stations maintained by the Ontario Ministry of the Environment for the period January 1, 1983 to December 31, 1988. Daily levels of sulfates were recorded at nine monitoring stations representing three different networks operated by the Ontario Ministry of the Environment and Environment Canada. Positive and statistically significant associations were found between hospital admissions and both ozone and sulfates recorded on the day of admission and up to 3 days prior to the date of admission. Five percent of daily respiratory admissions in the months of May to August were associated with ozone, with sulfates accounting for an additional 1% of these admissions. Ozone was a stronger predictor of admissions than sulfates. Positive and statistically significant (P < 0.05) associations were observed between the ozone-sulfate pollution mix and admissions for asthma, chronic obstructive pulmonary disease, and infections. Positive associations were also found in all age groups, with the largest impact on infants (15% of admissions associated with the ozone-sulfate pollution mix) and the least effects on the elderly (4%). Temperature had no effect on the air pollution-admission relationship. Ozone (lagged 1 day) and sulfates (lagged 1 day) displayed a positive association with respiratory admissions for 91 and 100% of the 168 acute care hospitals, respectively. Air pollution was not related to a class of nonrespiratory admissions, which served as a negative control, nor was it related to admissions in the winter months of December to March, when ozone and sulfate levels are low and when people spend a considerable amount of time indoors.
