RESUMEN
BACKGROUND: Obesity is a chronic and progressive disease associated with significant morbidity, mortality, and health-care costs. Bariatric surgery is the most effective intervention for sustainable weight loss and resolution of obesity-related comorbidities. Studies examining comorbidity resolution largely rely on individual self-reported outcomes and electronic record reviews. We present a population-based study looking at prescription medication utilization before and after bariatric surgery as a measure of comorbidity resolution. METHODS: All patients enrolled in the Center for Metabolic and Bariatric Surgery who underwent either gastric bypass or sleeve gastrectomy between 2013 and 2019 in Manitoba were included. Demographic information, follow up, and outpatient prescription dispensation data were obtained from the Manitoba Population Research Data Repository housed at the Manitoba Centre for Health Policy for 5 years pre- and post-surgery. RESULTS: A total of 1184 patients were included. Antidepressants and selective serotonin reuptake inhibitors were the most commonly prescribed classes, and along with thyroid medication, utilization remained stable after bariatric surgery. Proton pump inhibitors and opioid class drugs increased at 1 year after surgery then returned to baseline. Glucose and lipid-lowering medications, including statins, biguanides, sulfonylureas, and insulin, were decreased. Antihypertensives, including ACE inhibitors, calcium channel blockers, angiotensin receptors blockers, thiazides, and beta blockers, similarly decreased. CONCLUSION: This is the first Canadian study employing a provincial-wide prescription database to measure long-term comorbidity resolution after bariatric surgery. The use of administrative data eliminates potential biases and inaccuracies in follow up and self-reported outcomes. Consistent with the literature, prescriptions for the treatment of metabolic syndrome all decreased and were sustained at long-term follow up. Further studies are needed to delineate the effects of altered pharmaceutical utilization on patient quality of life and health-care expenditures.

OBJECTIVE: To determine if expansion of multi-use physical activity trails in an urban centre is associated with reduced rates of cardiovascular disease (CVD). METHODS: This was a natural experiment with a difference in differences analysis using administrative health records and trail-based cycling data in Winnipeg, Canada. Prior to the intervention, each year, 314,595 (IQR: 309,044 to 319,860) persons over 30 years without CVD were in the comparison group and 37,901 residents (IQR: 37,213 to 38,488) were in the intervention group. Following the intervention, each year, 303,853 (IQR: 302,843 to 304,465) persons were in the comparison group and 35,778 (IQR: 35,551 to 36,053) in the intervention group. The natural experiment was the construction of four multi-use trails, 4-7 km in length, between 2010 and 2012. Intervention and comparison areas were based on buffers of 400 m, 800 m and 1200 m from a new multi-use trail. Bicycle counts were obtained from electromagnetic counters embedded in the trail. The primary outcome was a composite of incident CVD events: CVD-related mortality, ischemic heart disease, cerebrovascular events and congestive heart failure. The secondary outcome was a composite of incident CVD risk factors: hypertension, diabetes and dyslipidemia. RESULTS: Between 2014 and 2018, 1,681,125 cyclists were recorded on the trails, which varied ~ 2.0-fold across the four trails (2358 vs 4264 counts/week in summer months). Between 2000 and 2018, there were 82,632 CVD events and 201,058 CVD risk events. In propensity score matched Poisson regression models, the incident rate ratio (IRR) was 1.06 (95% CI: 0.90 to 1.24) for CVD events and 0.95 (95%CI: 0.88 to 1.02) for CVD risk factors for areas within 400 m of a trail, relative to comparison areas. Sensitivity analyses indicated this effect was greatest among households adjacent to the trail with highest cycling counts (IRR = 0.85; 95% CI: 0.75 to 0.96). CONCLUSIONS: The addition of multi-use trails was not associated with differences in CVD events or CVD risk factors, however the differences in CVD risk may depend on the level of trail use. TRIAL REGISTRATION: Trial registration number: NCT04057417 .

OBJECTIVE: To describe the prevalence of mental health comorbidity in children with type 2 diabetes compared to a matched population without diabetes and children with type 1 diabetes. RESEARCH DESIGN AND METHODS: Population-based cohorts of 528 youth (7-18 years of age) with prevalent type 2 diabetes, 1519 matched children without diabetes and 778 youth with type 1 diabetes were identified from a clinical registry and linked to provincial health care records to assess the prevalence of mental health comorbidity using ICD-9CM, ICD-10CA and ATC codes. RESULTS: The majority of children with type 2 diabetes were of First Nations heritage. Compared to their matched peers, children with type 2 diabetes where more likely to have a mood or anxiety disorder before and after diagnosis [RR 2.38 (1.63, 3.48) p < 0.001 and 1.70 (1.39, 2.08) p < 0.001 respectively], to attempt/complete suicide [RR 3.18 (1.30, 7.81) p = 0.012 and 2.18 (1.32, 3.60) p = 0.0002 respectively] and be prescribed an antipsychotic [RR 2.33 (1.23, 4.39) p = 0.009 and 1.76 (1.23, 2.52) p = 0.002 respectively]. Following adjustment for age and sex, children with type 2 diabetes, compared to children with type 1 diabetes where more likely to have a mood or anxiety disorder and be prescribed an antipsychotic after diagnosis [RR 1.43 (1.07, 1.91) p = 0.015; RR 2.41 (1.44, 4.06) p = 0.0009 respectively]. CONCLUSIONS: Children with type 2 diabetes have high rates of comorbid mental illness. Programs to provide care, support, and education must address the mental health comorbidity in the context of the demographic, socioeconomic, and psycho-cultural characteristics of the population.

OBJECTIVE: To describe hospitalization rates and reasons for hospitalization in children with type 2 diabetes (T2D) and to compare these rates to a matched cohort without diabetes and to children with type 1 diabetes (T1D). METHODS: Population-based cohorts of 528 children (7-18 years of age) with prevalent T2D, 1519 matched control children without diabetes and 778 children with T1D were identified from a clinical registry and linked to health care records to assess hospitalizations and reasons for hospitalizations using ICD-9CM and ICD-10CA codes. RESULTS: Children with T2D are more likely than their matched controls and children with T1D to be admitted to hospital in the year prior to diagnosis {RR 2.83 (1.77, 4.53) p < 0.0001 and 8.05 (4.05, 16.00) p < 0.0001, respectively}, in the first year post diagnosis {RR 3.19 (2.08, 4.89) p < 0.0001 and 3.04 (1.86, 4.98) p < 0.0001, respectively} and in the 5 year post diagnosis period {RR 1.99 (1.56, 2.53) p < 0.0001 and 1.91 (1.48, 2.46) p < 0.0001, respectively}. Mental illness was the most common cause for hospital admission in both children with T2D and their matched controls. CONCLUSIONS: This differs from children with T1D where endocrine causes constitute the most common reason for hospital admission. This analysis provides novel data on hospitalization rates and diagnoses in the increasing population of children with T2D. This information is important to inform health care programming and health policy planning to best meet the needs of this population.

OBJECTIVE: To determine the rate of total knee replacement (TKR) after anterior cruciate ligament reconstruction (ACL-R) compared to the general population. DESIGN: Retrospective review. SETTING: All hospitals that performed TKR and ACL-R in Manitoba between 1980 and 2015. PARTICIPANT: All patients that underwent TKR and ACL-R in Manitoba between 1980 and 2015. INTERVENTION: Patient factors gathered at time of surgery included: age, sex, urban or rural residence, neighborhood income quintile, and resource utilization band (RUB). Each person was matched with up to 5 people from the general population who had never had ACL-R and had not had a TKR at the time of the case ACL-R. MAIN OUTCOME MEASURES: The rate of TKR after ACL-R. RESULTS: Overall from 1980 to 2015, 8500 ACL-R were identified within the 16 to 60 years age group with a resultant 42 497 population matches. Sex was predominantly male. The mean age of the ACL-R group at the time of TKR was 53.7 years, whereas the mean age for the matched cohort was 58.2 years, P < 0.001. Those with ACL-R were 4.85 times more likely to go on to have TKR. Apart from age, no other risk factors examined (location, year of surgery, place of residence, income quintile, and RUB) seemed to increase risk of TKR after ACL-R. CONCLUSION: Patients who underwent ACL-R were 5 times more likely to undergo TKR.

BACKGROUND: It is unclear whether intrauterine exposure to maternal diabetes is associated with risk factors for cardiovascular disease and related end points in adulthood. We examined this potential association in a population-based birth cohort followed up to age 35 years. METHODS: We performed a cohort study of offspring born between 1979 and 2005 (n = 293 546) and followed until March 2015 in Manitoba, Canada, using registry-based administrative data. The primary exposures were intrauterine exposure to gestational diabetes and type 2 diabetes mellitus. The primary outcome was a composite measure of incident cardiovascular disease events, and the secondary outcome was a composite of risk factors for cardiovascular disease in offspring followed up to age 35 years. RESULTS: The cohort provided 3 628 576 person-years of data (mean age at latest follow-up 20.5 [standard deviation 6.4] years, 49.3% female); 2765 (0.9%) of the offspring experienced a cardiovascular disease end point, and 12 673 (4.3%) experienced a cardiovascular disease risk factor. After propensity score matching, the hazard for cardiovascular disease end points was elevated in offspring exposed to gestational diabetes (adjusted hazard ratio [HR] 1.42, 95% confidence interval [CI] 1.12-1.79) but not type 2 diabetes (adjusted HR 1.40, 95% CI 0.98-2.01). A similar association was observed for cardiovascular disease risk factors (gestational diabetes: adjusted HR 1.92, 95% CI 1.75-2.11; type 2 diabetes: adjusted HR 3.40, 95% CI 3.00-3.85). INTERPRETATION: Intrauterine exposure to maternal diabetes was associated with higher morbidity and risk related to cardiovascular disease among offspring up to 35 years of age.

OBJECTIVE: To determine epidemiological trends of anterior cruciate ligament reconstruction (ACL-R) in a Canadian province, estimate the national incidence, and compare with internationally published data. DESIGN: Retrospective review. SETTING: All hospitals that performed ACL reconstructions in Manitoba between 1980 and 2015. PARTICIPANT: All patients that underwent ACL-R in Manitoba between 1980 and 2015. INTERVENTION: This is a retrospective review looking at deidentified, individual-level administrative records of health services used for the entire population of Manitoba (approximately 1.3 million). Codes for ACL and cruciate ligament reconstruction were searched from 1980 to 2015. Patient demographics included age, sex, geographic area of residence, and neighborhood income quintile. MAIN OUTCOME MEASURES: Trends of ACL reconstructions from 1980 to 2015. RESULTS: A total of 10 114 ACL-R were performed during the 36-year study period and patients were predominantly male (63.1%). The mean age at ACL-R was 29.5 years (SD 10.0) for males and 28.5 years (SD 11.9) for females, whereas age younger than 40 years accounted for 81.7% of all ACL-R. The incidence of ACL-R increased from 7.56/100 000 inhabitants in 1980 to 48.45/100 000 in 2015. The proportion of females undergoing ACL-R has increased from 29.3% in 1980% to 41.9% in 2015, and female patients now comprise the majority of ACL-R in the under-20 age category. CONCLUSION: The incidence of ACL-R has significantly increased since 1980; female patients now make up a greater proportion than males of the ACL-R population younger than 20 years. This information can be used to guide resource allocation planning and focus injury prevention initiatives.

OBJECTIVE: To determine the incidence and associated risk factors of developmental dysplasia of the hip (DDH) in a modern population without universal screening. STUDY DESIGN: Children with DDH were identified from the Manitoba Centre for Health Policy's Data Repository by the use of International Classification of Diseases diagnosis codes as well as physician billing tariffs for surgical procedures for DDH for all children born between 1995 and 2012. To identify the outpatient-treated patients, ultrasound scans and radiographic imaging for DDH were reviewed for 2004-2012. Overall incidence was calculated on the basis of birth rate for the province per year. Relative risks of sex, first born, breech position, clubfoot deformity, multiple gestations, as well as regional health areas were analyzed with χ2 tests. RESULTS: We identified 1716 cases of DDH of 258 499 newborns. The incidence of DDH was calculated at 6.6/1000 newborns. Late-presenting DDH was detected in 2.2/1000 newborns. Female first-born children, clubfoot deformity, and breech position were associated significantly with an increased risk. Children with DDH born in rural areas of the Northern and Central part of Manitoba presented at a later age than those who are born in the urban areas (P < .0001) CONCLUSION: This study shows the need for improved early detection and awareness at well-baby clinics of risk factors and regional differences for DDH.

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) are widely prescribed for mood and anxiety disorders. However, it is not clear whether SNRIs are more strongly associated with cardiovascular and cerebrovascular events than SSRIs. METHODS: This was a propensity score-matched, population-based, cohort study of Manitobans who started an SSRI or SNRI between April 1, 1998, and March 31, 2014. The primary outcome was a composite of acute myocardial infarction (AMI), stroke, or cardiovascular-related hospitalization within 1 year of drug initiation. Each component of the primary outcome and death were analyzed separately in secondary analyses. RESULTS: A total of 225,504 and 54,635 patients initiated treatment on an SSRI and SNRI, respectively. After propensity score matching, a higher risk was observed for the primary outcome among SNRI users (weighted hazards ratio [HR], 1.13; 95% confidence interval [CI], 1.06-1.21). Secondary analyses showed that the risk of nonfatal stroke was higher among SNRI users (weighted HR, 1.20; 95% CI, 1.08-1.33). The risk of death was higher among SNRI users without mood and/or anxiety disorders (weighted HR, 1.17; 95% CI; 1.03-1.32). No differences were observed in the risk of AMI or fatal stroke between SSRI and SNRI use. CONCLUSIONS: New SNRI use was associated with a higher risk of nonfatal stroke relative to SSRI use. Further investigation is warranted regarding the higher risk of death observed in our subgroup analysis among incident SNRI users without mood and/or anxiety disorders.

PURPOSE: Pharmacy claims data is often used in pharmacoepidemiology studies, but no studies to date have examined whether it was possible to identify the use of blister packs in these databases. We aimed to determine whether medications dispensed in days divisible by 7 are more likely to be blister packed than medications dispensed in other quantities. METHODS: Community pharmacies in Manitoba were invited to participate in a mail-out survey to identify the use of blister packaging for up to 25 patients who had a solid oral medication dispensed from April 1, 2012 to March 31, 2014. Eligible medications were identified using the population-based province-wide retail pharmacy network. Algorithms for identifying the use of blister packaging were determined by comparing the proportion of fills that confirmed blister pack use between different days supply quantities. RESULTS: Twenty-seven out of 32 pharmacies that agreed to participate completed the survey. The total number of prescriptions in the analysis was 2045 of which 131 (6.4%) were dispensed in blister packaging. Overall, prescriptions dispensed in days divisible by 7 yielded a 72.5% sensitivity, 86.6% specificity, 30.3% PPV, and 97.9% NPV compared with prescriptions dispensed in other quantities. A 28-day to 30-day comparison yielded an 87.9% sensitivity, 96.1% specificity, 64.6% PPV, and 99.0% NPV. CONCLUSION: While the NPV was high, the PPV for identifying blister packaging using the days supply field in pharmacy claims data was modest given the low prevalence in blister pack use. The best predictor occurred when 28 days was compared with 30 days. KEY POINTS Blister packs are arranged in 4 × 7 compartments and are often used to improve adherence, but no studies have examined whether it was possible to identify the use of blister packs using the days supply field in pharmacy claims data. Findings show that a 28-day supply yielded a high sensitivity and specificity for identifying the use of blister packaging compared with a 30-day supply, but there is potential for misclassification. Future studies directed at examining subgroups that are more likely to use blister packs and replication of findings using other data sources in other jurisdictions are encouraged.

Objective The late preterm population [34-36 weeks gestational age (GA)] is known to incur increased morbidity in the infancy stage compared to the population born at term (39-41 weeks GA). This study aimed to examine the health of these children during their early childhood years, with specific attention to the role of socioeconomic status. Methods A retrospective cohort study was conducted using data from the Manitoba Centre for Health Policy, including all live-born children born at 34-36 and 39-41 weeks GA in urban Manitoba between 2000 and 2005 (n = 28,100). Multivariable logistic regression was used to examine the association of GA with early childhood morbidity after controlling for maternal, child and family level variables. Results The late preterm population was found to have significantly greater adjusted odds of lower respiratory tract infections in the preschool years (aOR = 1.59 [1.24, 2.04]) and asthma at school age (aOR = 1.33 [1.18, 1.47]) compared to the population born at term. The groups also differed in health care utilization at ages 4 (aOR = 1.19 [1.06,1.34]) and 7 years (aOR = 1.24 [1.09, 1.42]). Additional variables associated with poor outcomes suggest that social deprivation and GA simultaneously have a negative impact on early childhood development. Conclusions for Practice Adjustment for predictors of poor early childhood development, including socioeconomic status, were found to attenuate but not eliminate health differences between children born late preterm and children born at term. Poorer health outcomes that extend into childhood have implications for practice at the population level and suggest a need for further follow-up post discharge.

OBJECTIVE: There has been much attention on appropriate prescribing in older adults in recent years. Recent guidelines favor the use of newer antidepressants over older agents based on their safety profile in this population. This study aimed to examine whether there has been a decline in older antidepressants and an increase in newer antidepressants used by older adults. METHOD: A retrospective cross-sectional study using administrative databases examined the annual incidence of antidepressant use (per 1000) of community-dwelling adults ≥60 years old between 1997/1998 and 2012/2013 in Manitoba, Canada. RESULTS: The population of Manitoba ≥60 years increased by 25.6% from 188,296 to 236,569 from 1997/1998 to 2012/2013. New antidepressant use peaked to 45.9 per 1000 in 1999/2000, and then decreased steadily to 30.5 per 1000 in 2012/2013 (p < 0.0001). Incident amitriptyline use was high but declined from 15.5 to 7.4 per 1000 (p < 0.001). An increase in incident trazodone, mirtazapine, and venlafaxine use was observed (p < 0.001). CONCLUSIONS: There has been an overall decrease in the annual incidence of antidepressant users in older adults over the last 16 years, with a marked decline in new amitriptyline use and an increase in the incidence of newer agents.

BACKGROUND: Registered midwives, obstetricians/gynecologists, and general or family practice physicians (GPs) provide maternity care across Canada. Few North American studies have assessed whether maternity outcomes differ across these three groups. This study compared maternal and neonatal outcomes of low-risk pregnant women whose birth was attended by registered midwives, obstetricians/gynecologists, and family practice physicians in Winnipeg, Manitoba from 2001/02 to 2012/13. METHODS: Descriptive statistics and logistic regression were used to examine differences in types of intervention, mode of delivery, and outcomes by provider type among low-risk women. Logistic regression models controlled for socio-demographic and birth-related covariates. RESULTS: Low-risk births comprised 83,774 (48.7%) of total births (n = 171,910). The adjusted odds ratio (aOR), (95% confidence interval) for midwife vs OB/GYN showed women who had a midwife attend the birth had reduced odds of having an episiotomy 0.47 (0.40-0.54), epidural 0.25 (0.23-0.27), and cesarean delivery 0.13 (0.10-0.16) and their infants had less Neonatal Intensive Care Unit admissions 0.28 (0.18-0.43). The aOR for GP versus OB/GYN showed women who had a GP had reduced odds of having an epidural/spinal 0.83 (0.79-0.88) and cesarean delivery 0.44 (0.40-0.48). CONCLUSIONS: The effectiveness of Manitoba maternity services can be improved with increased use of integrated midwifery services. Future research should examine how midwifery and physician-led models of care differ, and the influence of these differences on birth outcomes and cost-effectiveness to the health care system. Improvement of data tracking systems is also needed.

AIM: To describe the incidence and prevalence of type 2 diabetes in children in Manitoba over a ten-year period. METHODS: Population-based, provincial databases were linked to calculate the incidence and prevalence of type 2 diabetes in children < 18 years of age in Manitoba from 2009-10 to 2017-18. First Nation and all other Manitoban children are described separately. RESULTS: The incidence of type 2 diabetes increased from 16.0/100,000/year in 2009-10 to 31â§1/100,000/year in 2017-18 (p < 0.001). For First Nation children, the incidence increased from 73â§4 to 121â§2/100,000/year (p < 0.001). For all other Manitoban children, the incidence increased from 3â§3 to 10â§7/100,000/year (p < 0.001). The prevalence of type 2 diabetes rose from 66â§4 to 124â§2/100,000/year between 2009 -10 and 2017-18 (<0.001). The prevalence in First Nation children rose from 282â§8 to 517â§9/100,000/year (p < 0.001) and in all other Manitoban children from 18â§4 to 35.0/100,000/year (p < 0.001). CONCLUSIONS: The incidence and prevalence of type 2 diabetes is increasing in Manitoban children. While the greatest increase is seen in all other Manitoban children, type 2 diabetes disproportionally affects First Nation children. Understanding the prevalence and incidence of type 2 diabetes in children is necessary for resource allocation and to inform program planning, aimed at both prevention and management.

Factors affecting intrauterine environment exerts influence on skeletal health and fracture risk in later life. Diabetes during pregnancy is known to influence birth weight and is associated with fetal overgrowth. However, the effects of maternal diabetes on fracture risk in offspring is unknown. This study was aimed to evaluate the association between maternal diabetes and fracture risk in offspring. Using population-based administrative health data for Manitoba, Canada, we identified deliveries complicated by gestational diabetes and type 2 diabetes between April 1, 1980, and March 31, 2020. The cohort was followed for a median of 15.8 yr. The primary outcome was any incident fracture in offspring. Secondary outcomes were long bone upper extremity fracture, long bone lower extremity fracture, vertebral fracture, and any non-trauma fractures. Cox proportional hazard regression models were used to estimate fracture risk in offspring by maternal diabetes status adjusted for relevant covariates. Of the 585 176 deliveries, 26 397 offspring were born to women with diabetes (3.0% gestational diabetes and 1.5% type 2 diabetes), and 558 779 were born to women without diabetes. The adjusted risk for any fracture was 7% (hazard ratio, 1.07; 95% CI, 2.7-11.5%) higher in the offspring of mothers with diabetes than offspring of mothers without diabetes. Types of fractures were similar between the 2 groups with a predominance of long bone upper extremity fractures. In conclusion, maternal diabetes was associated with a modest increase in fracture risk in offspring. Longitudinal prospective studies are needed to understand intrauterine and postnatal factors that may influence fracture risk in the offspring of mothers with diabetes.

OBJECTIVES: The prevalence of type 2 diabetes (T2D) is increasing and Indigenous populations are at highest risk. Canadian data are crucial for health planning. METHODS: Population-based, de-identified, linked databases were used to calculate the incidence and prevalence of T2D for registered adult First Nations Manitobans and all other adult Manitobans from 2011-2012 to 2016-2017. RESULTS: The crude prevalence of T2D increased over the 6-year study period. The crude incidence of T2D for First Nations Manitobans dropped from 11.02 to 9.74 per 1,000 person-years at risk and the crude incidence for all other Manitobans did not change; in the last 2-year period, it was 6.53 per 1,000 person-years at risk. When incidence was stratified by age, the results differed between the younger and older age groups. For First Nations individuals, the adjusted incidence of T2D for those <30 years old increased over time, with no change in those ≥30 years old. For all other Manitobans, crude incidence increased over time in the young and middle age ranges (i.e. 18 to 29 years and 35 to 44 years, respectively). Both age- and sex-adjusted relative prevalence (adjusted rate ratio [aRR], 3.47; 95% confidence interval [CI], 2.56 to 4.70) and incidence (aRR, 1.97; 95% CI, 1.51 to 2.56) were higher for First Nations Manitobans. CONCLUSIONS: The prevalence of T2D continues to increase and disproportionately affects First Nations populations. Furthermore, the incidence is increasing in the younger age groups. Prevention and screening programs must include younger age groups and partner with First Nations communities.

Legg Calve Perthes disease is a pediatric hip condition that leads to early hip degeneration. The efficacy of operative and nonoperative treatment is not well defined in the literature. Using the rate of total hip arthroplasty as a surrogate measure for symptomatic hip degeneration, the rate of total hip arthroplasty was compared in Legg Calve Perthes disease patients with and without previous surgical intervention in the province of Manitoba, Canada. A retrospective review was conducted using de-identified, individual-level administrative records of health services for the entire population of Manitoba. Codes for Legg Calve Perthes disease, femoral osteotomies, pelvic osteotomies, adductor tenotomies, and total hip arthroplasty were searched from 1984 to 2018. The rate of total hip arthroplasty in patients with Legg Calve Perthes disease was determined for two groups: (1) patients with earlier surgical intervention and (2) patients with no previous surgical intervention. Of the 202 patients included in the study, 180 had no prior surgery and 22 had prior surgery. The rate of total hip arthroplasty between the previous operative and nonoperative groups was found to be 32% and 40%, respectively (p = 0.458). There was no significant difference in rates of total hip arthroplasty in the operative and nonoperative groups. Further prospective studies are required to elucidate the differences in outcomes between operative and nonoperative treatment groups in patients with Legg Calve Perthes disease.
RESUMEN
OBJECTIVES: Recent research has shown that cardiovascular disease (CVD) raises the risk of dementia and other forms of cognitive decline. Generally, these studies are unable to model the time of diagnosis of CVD in their analyses and treat CVD as a time-fixed variable. Our objective was to assess the risk of being diagnosed with dementia for individuals diagnosed with CVD when CVD is time-dependent. METHODS: We performed a retrospective cohort study using administrative health datasets from the Manitoba Population Research Data Repository in Canada. We constructed a longitudinal dataset to track individuals enrolled in the Manitoba Health Insurance Registry between April 1, 1997 and March 31, 2015. The study population consisted of 496,192 individuals 30 years of age or older who were not diagnosed with CVD or dementia prior to April 1, 1997. Diagnoses of CVD and dementia were based on diagnosis codes from medical claims and hospitalizations and the use of prescription medications. Hazard ratios were then computed using adjusted Cox-proportional hazards analyses. RESULTS: Among the CVD subgroups considered, atrial fibrillation, ischemic heart disease, and stroke increased the risk of developing dementia, with stroke doubling one's risk of being diagnosed with the disease (hazard ratio: 1.95; 95% confidence interval: 1.9, 2.01). Age, lower socioeconomic status, and worsening comorbidities also increased the risk of being diagnosed with dementia. CONCLUSION: A diagnosis of CVD is associated with an increased risk of a future diagnosis of dementia. Promoting good cardiovascular health may serve as an effective measure for preventing dementia.
RéSUMé: OBJECTIFS: De récentes études montrent que la maladie cardiovasculaire (MCV) accroît le risque de démence et d'autres formes de déclin cognitif. De façon générale, ces études sont incapables de modéliser la date d'un diagnostic de MCV dans leurs analyses et traitent donc les MCV comme des variables fixes dans le temps. Nous avons cherché à évaluer le risque de recevoir un diagnostic de démence chez les personnes ayant un diagnostic de MCV quand la MCV est variable dans le temps. MéTHODE: Nous avons mené une étude de cohorte rétrospective à l'aide des fichiers de données administratives sur la santé du Dépôt de données de recherche en santé des populations du Manitoba, au Canada. Nous avons construit un fichier longitudinal pour suivre les personnes inscrites au registre d'assurance-maladie du Manitoba entre le 1er avril 1997 et le 31 mars 2015. La population étudiée comptait 496 192 personnes de 30 ans et plus n'ayant pas reçu de diagnostic de MCV ou de démence avant le 1er avril 1997. Les diagnostics de MCV et de démence étaient fondés sur les codes diagnostiques dans les demandes d'indemnisation de frais médicaux et les dossiers d'hospitalisation, et sur l'utilisation de médicaments sur ordonnance. Les indices de risque ont été calculés à l'aide du modèle à risques proportionnels de Cox. RéSULTATS: Dans les sous-groupes atteints de MCV que nous avons étudiés, la fibrillation atriale, la cardiopathie ischémique et l'AVC faisaient augmenter le risque de démence; l'AVC, en particulier, doublait le risque d'être diagnostiqué avec cette maladie (indice de risque : 1,95; intervalle de confiance de 95% : 1,9, 2,01). L'âge, le faible statut socioéconomique et l'évolution défavorable des comorbidités faisaient aussi augmenter le risque de recevoir un diagnostic de démence. CONCLUSION: Un diagnostic de MCV est associé à un risque accru de diagnostic de démence plus tard. La promotion d'une bonne santé cardiovasculaire pourrait donc être un moyen efficace de prévenir la démence.

BACKGROUND AND AIMS: High-risk alcohol consumption is associated with compromised health. This study aimed to compare the incidence of alcohol-related cancers, diabetes, ischemic heart disease (IHD) and mortality between those with and without an indication of alcohol use disorder (AUD). DESIGN: Retrospective, population-based, matched cohort study using data from the Manitoba Population Research Data Repository. Rates were modeled using generalized linear models with either negative binomial distribution or Poisson distribution and a log offset of person-years to account for each person's time to follow-up. SETTING: Manitoba, Canada. PARTICIPANTS: Individuals aged ≥ 12 years with a first indication of AUD (index date) between 1 April 1990 and 31 March 2015 were matched to five controls based on age, sex and geographical region at index. This study included 53 410 individuals with AUD and 264 857 matched controls. MEASUREMENTS: Adjusted rate ratios (aRR) and 95% confidence intervals (CI) were determined for each outcome from 5 years prior to and 20 years after AUD detection. FINDINGS: Alcohol-related cancers (aRR = 4.85, 95% CI = 3.88-6.07 and aRR = 1.85, 95% CI = 1.35-2.53 for men and women, respectively), diabetes (aRR = 1.74, 95% CI = 1.50-2.02 and aRR = 2.43, 95% CI = 2.20-2.68) and IHD (aRR = 3.59, 95% CI = 3.31-3.90 and aRR = 2.92, 95% CI = 2.50-3.41) peaked in the 1 year prior to index for those with AUD compared with matched controls. All-cause mortality (aRR = 3.31, 95% CI = 3.09-3.55 and aRR =3.61, 95% CI = 3.21-4.04) was highest in the year of index and remained higher among cases compared with controls throughout the 20-year follow-up. CONCLUSION: People with alcohol use disorder appear to have higher rates of adverse health outcomes in the year before alcohol use disorder recognition, and death at the time of alcohol use disorder recognition, compared with matched controls.
