RESUMO
OBJECTIVE: Little is known about how prenatal care influences health outcomes in Canada. The objective of this study was to examine the association of prenatal care utilization with maternal, fetal, and infant outcomes in Manitoba. METHODS: This retrospective cohort study conducted at the Manitoba Centre for Health Policy investigated all deliveries of singleton births from 2004-2005 to 2008-2009 (Nâ¯=â¯67 076). The proportion of women receiving inadequate, intermediate/adequate, and intensive prenatal care was calculated. Multivariable logistic regression was used to examine the association of inadequate and intensive prenatal care with maternal and fetal-infant health outcomes, health care use, and maternal health-related behaviours. RESULTS: The distribution of prenatal care utilization was 11.6% inadequate, 84.4% intermediate/adequate, and 4.0% intensive. After adjusting for sociodemographic factors and maternal health conditions, inadequate prenatal care was associated with increased odds of stillbirth, preterm birth, low birth weight, small for gestational age (SGA), admission to the NICU, postpartum depressive/anxiety disorders, and short interpregnancy interval to next birth. Women with inadequate prenatal care had reduced odds of initiating breastfeeding or having their infant immunized. Intensive prenatal care was associated with reduced odds of stillbirth, preterm birth, and low birth weight and increased odds of postpartum depressive/anxiety disorders, initiation of breastfeeding, and infant immunization. CONCLUSION: Inadequate prenatal care was associated with increased odds of several adverse pregnancy outcomes and lower likelihood of health-related behaviours, whereas intensive prenatal care was associated with reduced odds of some adverse pregnancy outcomes and higher likelihood of health-related behaviours. Ensuring women receive adequate prenatal care may improve pregnancy outcomes.

BACKGROUND: Ensuring high quality and equitable maternity services is important to promote positive pregnancy outcomes. Despite a universal health care system, previous research shows neighborhood-level inequities in utilization of prenatal care in Manitoba, Canada. The purpose of this population-based retrospective cohort study was to describe prenatal care utilization among women giving birth in Manitoba, and to determine individual-level factors associated with inadequate prenatal care. METHODS: We studied women giving birth in Manitoba from 2004/05-2008/09 using data from a repository of de-identified administrative databases at the Manitoba Centre for Health Policy. The proportion of women receiving inadequate prenatal care was calculated using a utilization index. Multivariable logistic regressions were used to identify factors associated with inadequate prenatal care for the population, and for a subset with more detailed risk information. RESULTS: Overall, 11.5% of women in Manitoba received inadequate, 51.0% intermediate, 33.3% adequate, and 4.1% intensive prenatal care (N = 68,132). Factors associated with inadequate prenatal care in the population-based model (N = 64,166) included northern or rural residence, young maternal age (at current and first birth), lone parent, parity 4 or more, short inter-pregnancy interval, receiving income assistance, and living in a low-income neighborhood. Medical conditions such as multiple birth, hypertensive disorders, antepartum hemorrhage, diabetes, and prenatal psychological distress were associated with lower odds of inadequate prenatal care. In the subset model (N = 55,048), the previous factors remained significant, with additional factors being maternal education less than high school, social isolation, and prenatal smoking, alcohol, and/or illicit drug use. CONCLUSION: The rate of inadequate prenatal care in Manitoba ranged from 10.5-12.5%, and increased significantly over the study period. Factors associated with inadequate prenatal care included geographic, demographic, socioeconomic, and pregnancy-related factors. Rates of inadequate prenatal care varied across geographic regions, indicating persistent inequities in use of prenatal care. Inadequate prenatal care was associated with several individual indicators of social disadvantage, such as low income, education less than high school, and social isolation. These findings can inform policy makers and program planners about regions and populations most at-risk for inadequate prenatal care and assist with development of initiatives to reduce inequities in utilization of prenatal care.

OBJECTIVE: To examine associations between breastfeeding initiation and subsequent diabetes among First Nations (indigenous people in Canada who are not Métis or Inuit) and non-First Nations mothers and their offspring with and without gestational diabetes mellitus (GDM). METHODS: This retrospective database study included 334,553 deliveries (1987-2011) in Manitoba with up to 24 years of follow-up for diabetes using population-based databases. Information of breastfeeding initiation before hospital discharge was obtained from hospital abstracts recorded by nurses in postpartum wards. Cox proportional hazard models were applied to examine the association between breastfeeding initiation and risk of diabetes in mothers and their offspring. RESULTS: Breastfeeding initiation was recorded in 83% of non-First Nations mothers and 56% of First Nations mothers (P<.001). Breastfeeding initiation was associated with a reduced risk of incident (later developed) diabetes in non-First Nations mothers without GDM (hazard ratio [HR] 0.73 [or -27% of risk], 95% confidence interval [CI] 0.68-0.79), non-First Nations mothers with GDM (HR 0.78 or -22% of risk, CI 0.69-0.89), First Nations mothers without GDM (HR 0.89 or -11% of risk, CI 0.81-0.98), and First Nations mothers with GDM (HR 0.82 or -18% of risk, CI 0.73-0.92) with 24 years of follow-up or less. With 24 years of follow-up or less, breastfeeding initiation was associated with a 17% lower risk of youth-onset type 2 diabetes in offspring (HR 0.83, CI 0.69-0.99, P=.038). The association between breastfeeding initiation and subsequent diabetes in mothers and offspring was independent of family income, rural residence, First Nations status, GDM, parity, gestational hypertension, and age of the mother. CONCLUSION: Breastfeeding initiation is associated with a reduced risk of diabetes among women and their offspring in Manitoba. The results suggest that breastfeeding might be a potentially modifiable factor to reduce the risk of diabetes in both First Nations and non-First Nations women and children.

OBJECTIVE: Type 2 diabetes is increasing in children worldwide, with Canadian First Nations (FN) children disproportionally affected. The prevalence of gestational diabetes mellitus (GDM) also is increasing. The objective of this study was to evaluate the impact of GDM exposure in utero and FN status on the subsequent risk of type 2 diabetes in offspring in the first 30 years of life. RESEARCH DESIGN AND METHODS: In this population-based historical prospective cohort study, we used administrative databases linked to a clinical database to explore the independent association and interaction between GDM and FN status on the subsequent development of type 2 diabetes in offspring. RESULTS: Among 321,008 births with a median follow-up of 15.1 years, both maternal GDM and FN status were independently associated with subsequent risk of type 2 diabetes in offspring in the first 30 years of life (hazard ratio 3.03 [95% CI 2.44-3.76; P < 0.0001] vs. 4.86 [95% CI 4.08-5.79; P < 0.0001], respectively). No interaction between GDM and FN status on type 2 diabetes risk was observed. FN status had a stronger impact on the development of type 2 diabetes in offspring than GDM. CONCLUSIONS: GDM is an important modifiable risk factor for type 2 diabetes, and its prevention may reduce the prevalence of subsequent type 2 diabetes in offspring. This study adds unique and rigorous evidence to the global public health debate about the impact of GDM on the long-term health of offspring.

BACKGROUND AND OBJECTIVES: Perinatal outcomes have improved in developed countries but remain poor for disadvantaged populations. We examined whether an unconditional income supplement to low-income pregnant women was associated with improved birth outcomes. METHODS: This study included all mother-newborn pairs (2003-2010) in Manitoba, Canada, where the mother received prenatal social assistance, the infant was born in the hospital, and the pair had a risk screen (N = 14 591). Low-income women who received the income supplement (Healthy Baby Prenatal Benefit [HBPB], n = 10 738) were compared with low-income women who did not receive HBPB (n = 3853) on the following factors: low birth weight, preterm, small and large for gestational age, Apgar score, breastfeeding initiation, neonatal readmission, and newborn hospital length of stay (LOS). Covariates from risk screens were used to develop propensity scores and to balance differences between groups in regression models; γ sensitivity analyses were conducted to assess sensitivity to unmeasured confounding. Population-attributable and preventable fractions were calculated. RESULTS: HBPB was associated with reductions in low birth weight (aRR, 0.71 [95% CI, 0.63-0.81]), preterm births (aRR, 0.76 [95% CI, 0.69-0.84]) and small for gestational age births (aRR, 0.90 [95% CI, 0.81-0.99]) and increases in breastfeeding (aRR, 1.06 [95% CI, 1.03-1.09]) and large for gestational age births (aRR, 1.13 [95% CI, 1.05-1.23]). For vaginal births, HBPB was associated with shortened LOS (weighted mean, 2.86; P < .0001). Results for breastfeeding, low birth weight, preterm birth, and LOS were robust to unmeasured confounding. Reductions of 21% (95% CI, 13.6-28.3) for low birth weight births and 17.5% (95% CI, 11.2-23.8) for preterm births were associated with HBPB. CONCLUSIONS: Receipt of an unconditional prenatal income supplement was associated with positive outcomes. Placing conditions on income supplements may not be necessary to promote prenatal and perinatal health.

BACKGROUND: In Manitoba, Canada, school-based clinics providing sexual and reproductive health services for adolescents have been implemented to address high rates of sexually transmitted infections (STIs) and pregnancies. METHODS: The objectives of this population-based study were to compare pregnancy and STI rates between adolescents enrolled in schools with school-based clinics, those in schools without clinics, and those not enrolled in school. Data were from the PATHS Data Resource held in the Population Health Research Data Repository housed at the Manitoba Centre for Health Policy. Adolescents aged 14 to 19 between 2003 and 2009 were included in the study. Annualized rates of pregnancies and positive STI tests were estimated and Poisson regression models were used to test for differences in rates amongst the three groups. RESULTS: As a proportion, pregnancies among non-enrolled female adolescents accounted for 55 % of all pregnancies in this age group during the study period. Pregnancy rates were 2-3 times as high among non-enrolled female adolescents. Compared to adolescents enrolled in schools without school-based clinics, age-adjusted STI rates were 3.5 times (p < .001) higher in non-enrolled males and 2.3 times (p < .001) higher in non-enrolled females. CONCLUSIONS: The highest rates for pregnancies and STIs were observed among non-enrolled adolescents. Although provision of reproductive and health services to in-school adolescents should remain a priority, program planning and design should consider optimal strategies to engage out of school youth.

The objective of this study was to examine mental disorders and treatment use among bereaved siblings in the general population. Siblings (N=7243) of all deceased children in the population of Manitoba, Canada who died between 1984 and 2009 were matched 1:3 to control siblings (N=21,729) who did not have a sibling die in the study period. Generalized estimating equations were used to compare the two sibling groups in the two years before and after the index child's death on physician-diagnosed mental disorders and treatment utilization, with adjustment for confounding factors including pre-existing mental illness. Analyses were stratified by age of the bereaved (<13 vs. 13+). Results revealed that, in the two years after the death of the child, bereaved siblings had significantly higher rates of mental disorders than control siblings, even after adjusting for pre-existing mental illness. When comparing the effect of a child's death on younger versus older siblings, the rise in depression rates from pre-death to post-death was significantly higher for siblings aged under 13 (p<0.0001), increasing more than 7-fold (adjusted relative rate, ARR=7.25, 95% CI: 3.65-14.43). Bereaved siblings aged 13+ had substantial morbidity in the two years after the death: 25% were diagnosed with a mental disorder (vs. 17% of controls), and they had higher rates of almost all mental disorder outcomes compared to controls, including twice the rate of suicide attempts (ARR=2.01, 95% CI: 1.29-3.12). Siblings in the bereaved cohort had higher rates of alcohol and drug use disorders already before the death of their sibling. In conclusion, the death of a child is associated with considerable mental disorder burden among surviving siblings. Pre-existing health problems and social disadvantage do not fully account for the increase in mental disorder rates.
RESUMO
OBJECTIVES: To review and synthesize the currently available research on whether early intervention for psychosis programs reduce the use of inpatient services. METHODS: A systematic review was conducted using keywords searches on PubMed, Embase (Ovid), PsycINFO (ProQuest), Scopus, CINAHL (EBSCO), Social Work Abstracts (EBSCO), Social Science Citations Index (Web of Science), Sociological Abstracts (ProQuest), and Child Development & Adolescent Studies (EBSCO). To be included, studies had to be peer-reviewed publications in English, examining early intervention programs using a variant of assertive community treatment, with a control/comparison group, and reporting inpatient service use outcomes. The primary outcome extracted number hospitalized and total N. Secondary outcome extracted means and standard deviations. Data were pooled using random effects models. Primary outcome was the occurrence of any hospitalization during treatment. A secondary outcome was the average bed-days used during treatment period. RESULTS: Fifteen projects were identified and included in the study. Results of meta-analysis supported the occurrence of a positive effect for intervention for both outcome measures (any hospitalization OR: 0.33; 95% CI 0.18-0.63, bed-days usage SMD: -0.38, 95% CI -0.53 to -0.24). There was significant heterogeneity of effect across the studies. This heterogeneity is due to a handful of studies with unusually positive responses. CONCLUSION: These results suggest that early intervention programs are superior to standard of care, with respect to reducing inpatient service usage. Wider use of these programs may prevent the occurrence of admission for patients experiencing the onset of psychotic symptoms.

INTRODUCTION: Caries is the most common chronic disease of childhood, and severe forms may necessitate rehabilitative dental surgery. In this study, administrative data related to pediatric dental surgery performed under general anesthesia to treat severe early childhood caries in Manitoba, Canada, were reviewed to determine trends in pediatric dental surgery, as well as geographic, regional and socio-economic variations in surgical rates. METHODS: The total number of dental surgery cases performed under general anesthesia was obtained from provincial administrative databases for fiscal years from 1997-98 to 2006-07. Codes from the International Classification of Diseases and Related Health Problems (9th or 10th revision, as appropriate) were used to identify children who underwent extractions under general anesthesia for a slightly earlier fiscal year period (1996-97 to 2005-06). Each 10-year period was divided into two 5-year periods for comparisons over time. Analyses included descriptive and bivariate statistics, with the data being disaggregated by regional health authority (RHA) or by community area (for Winnipeg). Comparisons for which p ≤ 0.05 were defined as statistically significant. RESULTS: A total of 18,544 children had dental surgery under general anesthesia between 1997-98 and 2006-07 (mean age ± standard deviation 3.28 ± 1.02 years). Many of the children requiring surgery resided in one northern RHA (26.8%) or the Winnipeg RHA (23.8%). More than half of the RHAs (7/11) displayed significant increases in the rate of surgery, with northern RHAs having the highest rates. Within Winnipeg, 3 of the 12 community areas had significant increases in the rate of surgery. Two inner-city neighborhoods accounted for nearly 50% of surgical cases. The rate of extractions under general anesthesia increased significantly in 6 of the 11 RHAs, with northern RHAs having the highest rates. Four Winnipeg communities experienced significant increases in the extraction rate over time. CONCLUSION: Pediatric dental surgery under general anesthesia for treatment of severe early childhood caries is common in Manitoba, and the demand increased in several communities over the study period. These results are being shared with decision-makers and communities to identify regions where oral health promotion is needed.

OBJECTIVES: Breastfeeding is associated with improved health. Surveillance data show that breastfeeding initiation rates have increased; however, limited work has examined trends in socio-economic inequalities in initiation. The study's research question was whether socio-economic inequalities in breastfeeding initiation have changed over the past 20 years. METHODS: This population-based study is a project within PATHS Equity for Children. Analyses used hospital discharge data for Manitoba mother-infant dyads with live births, 1988-2011 (n=316,027). Income quintiles were created, each with ~20% of dyads. Three-year, overall and by-quintile breastfeeding initiation rates were estimated for Manitoba and two hospitals. Age-adjusted rates were estimated for Manitoba. Rates were modelled using generalized linear models. Three measures, rate ratios (RRs), rate differences (RDs) and concentration indices, assessed inequality at each time point. We also compared concentration indices with Gini coefficients to assess breastfeeding inequality vis-à-vis income inequality. Trend analyses tested for changes over time. RESULTS: Manitoba and Hospital A initiation rates increased; Hospital B rates did not change. Significant inequalities existed in nearly every period, across all three measures: RRs, RDs and concentration indices. RRs and concentration indices suggested little to no change in inequality from 1988 to 2011. RDs for Manitoba (comparing initiation in the highest to lowest income quintiles) did not change significantly over time. RDs decreased for Hospital A, suggesting decreasing socio-economic inequalities in breastfeeding; RDs increased for Hospital B. Income inequality increased significantly in Manitoba during the study period. CONCLUSIONS: Overall breastfeeding initiation rates can improve while inequality persists or worsens.

OBJECTIVES: We explored differences in health and education outcomes between children living in social housing and not, and effects of social housing's neighborhood socioeconomic status. METHODS: In this cohort study, we used the population-based repository of administrative data at the Manitoba Centre for Health Policy. We included children aged 0 to 19 years in Winnipeg, Manitoba, in fiscal years 2006-2007 to 2008-2009 (n = 13,238 social housing; n = 174,017 others). We examined 5 outcomes: age-2 complete immunization, a school-readiness measure, adolescent pregnancy (ages 15-19 years), grade-9 completion, and high-school completion. Logistic regression and generalized estimating equation modeling generated rates. We derived neighborhood income quintiles (Q1 lowest, Q5 highest) from average household income census data. RESULTS: Children in social housing fared worse than comparative children within each neighborhood income quintile. When we compared children in social housing by quintile, preschool indicators (immunization and school readiness) were similar, but adolescent outcomes (grade-9 and high-school completion, adolescent pregnancy) were better in Q3 to Q5. CONCLUSIONS: Children in social housing had poorer health and education outcomes than all others, but living in social housing in wealthier areas was associated with better adolescent outcomes.

The PATHS Data Resource is a unique database comprising data that follow individuals from the prenatal period to adulthood. The PATHS Resource was developed for conducting longitudinal epidemiological research into child health and health equity. It contains individual-level data on health, socioeconomic status, social services and education. Individuals' data are linkable across these domains, allowing researchers to follow children through childhood and across a variety of sectors. PATHS includes nearly all individuals that were born between 1984 and 2012 and registered with Manitoba's universal health insurance programme at some point during childhood. All PATHS data are anonymized. Key concepts, definitions and algorithms necessary to work with the PATHS Resource are freely accessible online and an interactive forum is available to new researchers working with these data. The PATHS Resource is one of the richest and most complete databases assembled for conducting longitudinal epidemiological research, incorporating many variables that address the social determinants of health and health equity. Interested researchers are encouraged to contact [mchp_access@cpe.umanitoba.ca] to obtain access to PATHS to use in their own programmes of research.

INTRODUCTION: Despite a reported socioeconomic gradient in health, little is known about relationship between socioeconomic status (SES) and frequency of dog-bite injuries. The primary objective of this study was to compare the frequency of dog-bite injuries, using data on dog-bite injury hospitalizations (DBIH), across different SES areas in Manitoba, Canada. The secondary objective of the study was to assess if frequency and pattern of DBIHs are similar to those of non-canine bite injury hospitalizations (NCBIH) and rabies post-exposure prophylaxis (PEP). SES grouping in this study was defined through rurality and area-wide income quintile groups. METHODS: Rural and urban Manitoba neighbourhoods were ranked according to average area-level incomes into five levels (quintiles) with equal numbers of people in each income level. Prevalence was defined as the number of cases of hospitalizations (whether dog-bite injury or non-canine bite injury) or PEP reported in the years 1984-2006, divided by the total population during the same time period and expressed as the number of cases per 100 000 population per SES grouping. The 95% confidence intervals (CI) were calculated using the approach for Poisson distribution. RESULTS: During 1984-2006, Manitoba's prevalence (CI) of DBIH (3.19 (2.97, 3.41) per 100 000 population) was lower than prevalence of NCBIH (4.08 (3.84, 4.32)) and PEP (7.24 (6.92, 7.57)). Prevalence of DBIH was higher in rural than in urban areas (DBIH: 3.58 (3.24, 3.92) vs 2.87 (2.59, 3.15), p<0.01) and higher in the lowest income quintile areas than in the highest, whether rural (5.18 (4.24, 6.26) vs 3.29 (2.55, 4.17), p<0.0001) or urban (3.65 (2.97, 4.44) vs 2.24 (1.73, 2.87), p<0.01). The patterns of relationship between SES (rurality and income levels) and prevalence of NCBIH and PEP were similar to those between SES and DBIH. CONCLUSIONS: Although only a descriptive study, the results suggest that policies for control of dog-bite injuries should be area-specific. Prevention efforts could perhaps be improved by focussing not only on families, but also on neighbourhood regions.

BACKGROUND: Evaluation of the effectiveness of a patient decision aid (nurse-managed telephone support line and/or colorectal cancer screening website), distributed to patients by their family physician, in improving fecal occult blood test (FOBT) colorectal cancer screening rates. METHODS: A pragmatic, two arm, cluster randomized controlled trial in Winnipeg, Manitoba, Canada (39 medical clinic clusters; 79 fee-for-service family physicians; 2,395 average risk patients). All physicians followed their standard clinical screening practice. Intervention group physicians provided a fridge magnet to patients that facilitated patient decision aid access. Primary endpoint was FOBT screening rate within four months.Multi-level logistic regression to determine effect of cluster, physician, and patient level factors on patient FOBT completion rate. ICC determined. RESULTS: Family physicians were randomized to control (n = 39) and intervention (n = 40) groups. Compared to controls (56.9%; n = 663/1165), patients receiving the intervention had a higher FOBT completion rate (66.6%; n = 805/1209; OR of 1.47; 95% confidence interval 1.06 to 2.03; p < 0.02). Patient aid utilization was low (1.1%; 13/1,221) and neither internet nor telephone access affected screening rates for the intervention group. FOBT screening rates differed among clinics and physicians (p < 0.0001). Patients whose physician promoted the FOBT were more likely to complete it (65%; n = 1140/1755) compared to those whose physician did not (51.1%; n = 242/470; p < 0.0001; OR of 1.54 and 95% CI of 1.23 to 1.92). Patients reporting they had done an FOBT in the past were more likely to complete the test (70.6%; n = 1141/1616; p < 0.0001; 95% CI 2.51 to 3.73) than those who had not (43%; n = 303/705). Patients 50-59 years old had lower screening rates compared to those over 60 (p < 0.0001). 75% of patients completing the test did so in 34 days. CONCLUSION: Despite minimal use of the patient aid, intervention group patients were more likely to complete the FOBT. Powerful strategies to increase colorectal cancer screening rates include a recommendation to do the test from the family physician and focusing efforts on patients age 50-59 years to ensure they complete their first FOBT. TRIAL REGISTRATION NUMBER: clinicaltrials.gov identifier NCT01026753.

OBJECTIVE: To compare the causes and rates of death for people with and without schizophrenia in Manitoba, Canada. METHOD: Using de-identified administrative databases at the Manitoba Centre for Health Policy, a population-based analysis was performed to compare age- and sex-adjusted 10-year (1999-2008) mortality rates, overall and by specific cause, of decedents aged 10 years or older who had 1 diagnosis of schizophrenia (ICD-9-CM code 295, ICD-10-CA codes F20, F21, F23.2, F25) over a 12-year period (N = 9,038) to the rest of the population (N = 969,090). RESULTS: The mortality rate for those with schizophrenia was double that of the rest of the population (20.00% vs. 9.37%). The all-cause mortality rate was higher for people with schizophrenia compared to all others (168.9 vs. 99.1 per thousand; relative risk [RR] = 1.70, P < .0001); rates of death due to suicide (RR = 8.67, P < .0001), injury (RR = 2.35, P < .0001), respiratory illness (RR = 2.00, P < .0001), and circulatory illness (RR = 1.64, P < .0001) were also significantly higher in people with schizophrenia. Overall cancer deaths were similar (28.6 vs. 27.3 per thousand, P = .42, NS) except in the middle-aged group (40-59), in which cancer death rates were significantly higher for those with schizophrenia (28.7 vs. 11.6 per thousand; RR = 2.48, P < .01). Mortality rates due to lung cancer were significantly higher in people with schizophrenia (9.4 vs. 6.4 per thousand, RR = 1.45, P < .001). CONCLUSIONS: People with schizophrenia are at increased risk of death compared to the general population, and the majority of these deaths are occurring in older age from physical disease processes. Risk of cancer mortality is significantly higher in middle-aged but not younger or older patients with schizophrenia. Understanding these patients' vulnerabilities to physical illness has important public health implications for prevention, screening, and treatment as the population ages.

BACKGROUND: National health surveys are sometimes used to provide estimates on risk factors for policy and program development at the regional/local level. However, as regional/local needs may differ from national ones, an important question is how to also enhance capacity for risk factor surveillance regionally/locally. METHODS: A Think Tank Forum was convened in Canada to discuss the needs, characteristics, coordination, tools and next steps to build capacity for regional/local risk factor surveillance. A series of follow up activities to review the relevant issues pertaining to needs, characteristics and capacity of risk factor surveillance were conducted. RESULTS: Results confirmed the need for a regional/local risk factor surveillance system that is flexible, timely, of good quality, having a communication plan, and responsive to local needs. It is important to conduct an environmental scan and a gap analysis, to develop a common vision, to build central and local coordination and leadership, to build on existing tools and resources, and to use innovation. CONCLUSIONS: Findings of the Think Tank Forum are important for building surveillance capacity at the local/county level, both in Canada and globally. This paper provides a follow-up review of the findings based on progress over the last 4 years.
RESUMO
OBJECTIVE: To evaluate the risk of complications in youth with type 2 diabetes. RESEARCH DESIGN AND METHODS: Population-based cohorts of 342 youth (1-18 years of age) with prevalent type 2 diabetes, 1,011 youth with type 1 diabetes, and 1,710 nondiabetic control youth were identified between 1986 and 2007 from a clinical registry and linked to health care records to assess long-term outcomes using ICD-9CM and ICD-10CA codes. RESULTS: Youth with type 2 diabetes had an increased risk of any complication (hazard ratio 1.47 [95% CI 1.02-2.12]). Significant adverse clinical factors included age at diagnosis (1.08 [1.02-2.12]), HbA1c (1.06 [1.01-1.12]), and, surprisingly, renin-angiotensin-aldosterone system (RAAS) inhibitor use (1.75 [1.27-2.41]). HNF-1α G319S polymorphism was protective in the type 2 diabetes cohort (0.58 [0.34-0.99]). Kaplan-Meier statistics revealed an earlier diagnosis of renal and neurologic complications in the type 2 diabetes cohort, manifesting within 5 years of diagnosis. No difference in retinopathy was seen. Cardiovascular and cerebrovascular diseases were rare; however, major complications (dialysis, blindness, or amputation) started to manifest 10 years after diagnosis in the type 2 diabetes cohort. Youth with type 2 diabetes had higher rates of all outcomes than nondiabetic control youth and an overall 6.15-fold increased risk of any vascular disease. CONCLUSIONS: Youth with type 2 diabetes exhibit complications sooner than youth with type 1 diabetes. Younger age at diagnosis is potentially protective, and glycemic control is an important modifiable risk factor. The unexpected adverse association between RAAS inhibitor use and outcome is likely a confounder by indication; however, further evaluation in young people is warranted.

Motor vehicle collisions (MVCs) are the leading cause of death in young people in North America. The effects of such deaths on parents have not been systematically studied. Administrative data sets were used to identify all parents (n = 1,458) who had an offspring die in a MVC between 1996 and 2008 in the province of Manitoba, Canada. They were matched to general population control parents who had not had offspring die from any sudden cause during the study period. Generalized estimating equations were used to compare the rates of physician-diagnosed mental and physical disorders, social factors, and treatment utilization in the 2 parent groups in the 2 years before and after offspring death, with adjustment for confounding factors. The risk of depression among bereaved parents almost tripled (adjusted prevalence ratio = 2.85, 95% confidence interval: 2.44, 3.33; P < 0.001) during the 2 years after death of an offspring. Significant increases in the risk of anxiety disorders (adjusted prevalence ratio = 1.45, 95% confidence interval: 1.26, 1.67; P < 0.001) were also observed. When compared with nonbereaved parents, bereaved parents had significant increases in the risks of depression (P < 0.001), anxiety disorders (P < 0.001), marital break-up (P = 0.015), and physician visits for mental illness (P < 0.001) in the post-death period. In conclusion, parents who lose an offspring in a MVC experience considerable mental illness and marital disruption.
