Regional variations in the economic burden attributable to excess weight, physical inactivity and tobacco smoking across British Columbia.

INTRODUCTION: Prevalence rates of excess weight, tobacco smoking and physical inactivity vary substantially by geographical region within British Columbia (B.C.). The purpose of this study is to determine the potential reduction in economic burden in B.C. if all regions in the province achieved prevalence rates of these three risk factors equivalent to those of the region with the lowest rates. METHODS: We used a previously developed approach based on population-attributable fractions to estimate the economic burden associated with the various risk factors. Sex-specific relative risk and age/sex-specific prevalence data was used in the modelling. RESULTS: The annual economic burden attributable to the three risk factors in B.C. was about $5.6 billion in 2013, with a higher proportion of this total attributable to excess weight ($2.6 billion) than to tobacco smoking ($2.0 billion). While B.C. has lower prevalence rates of the risk factors than any other Canadian province, there is significant variation within the province. If each region in the province were to achieve the best prevalence rates for the three risk factors, then $1.4 billion (24% of the $5.6 billion) in economic burden could be avoided annually. CONCLUSION: There are notable disparities in the prevalence of each risk factor across health regions within B.C., which were mirrored in each region's attributable economic burden. A variety of social, environmental and economic factors likely drive some of this geographical variation and these underlying factors should be considered when developing prevention programs.

TITRE: Écarts régionaux dans le fardeau économique attribuable au surplus de poids, à la sédentarité et à l'usage du tabac en Colombie-Britannique. INTRODUCTION: Les taux de prévalence du surplus de poids, de l'usage du tabac et de la sédentarité varient sensiblement d'une région à l'autre en Colombie-Britannique (C.-B.). La présente étude vise à déterminer la portée d'une éventuelle réduction du fardeau économique en C.-B. si toutes les régions de la province atteignaient des taux de prévalence équivalents à ceux de la région dont les taux sont les plus bas pour ces trois facteurs de risque. MÉTHODOLOGIE: Nous avons utilisé une approche élaborée précédemment fondée sur la fraction étiologique du risque pour estimer le fardeau économique associé aux divers facteurs de risque. Le risque relatif selon le sexe et les données de prévalence selon l'âge et le sexe ont été utilisés dans la modélisation. RÉSULTATS: Le fardeau économique annuel attribuable à ces trois facteurs de risque en C.-B. s'élevait à environ 5,6 milliards de dollars en 2013, la proportion la plus élevée de ce total étant attribuable au surplus de poids (2,6 milliards), suivie de celle de l'usage du tabac (2 milliards). Même si la C.-B. possède des taux de prévalence de ces facteurs de risque plus bas que toute autre province canadienne, il existe d'importants écarts en son sein. Si chaque région de la province devait atteindre les taux de prévalence les plus bas pour les trois facteurs de risque, un fardeau économique de 1,4 milliard (24 % du total de 5,6 milliards) pourrait être supprimé annuellement. CONCLUSION : Il existe des disparités notables dans la prévalence de chacun des facteurs de risque au sein des régions sanitaires de la C.-B., qui se reflètent dans le fardeau économique attribuable à chaque région. Un éventail de facteurs sociaux, environnementaux et économiques expliquent probablement une partie de ces écarts géographiques, et ces facteurs sous-jacents devraient être pris en compte lors de la mise en place de programmes de prévention.

Barth syndrome: an X-linked cause of fetal cardiomyopathy and stillbirth.

OBJECTIVE: Barth Syndrome (BTHS) is an X-linked multisystem disorder (OMIM 302060) usually diagnosed in infancy and characterized by cardiac problems [dilated cardiomyopathy (DCM) ± endocardial fibroelastosis (EFE) ± left ventricular non-compaction (LVNC)], proximal myopathy, feeding problems, growth retardation, neutropenia, organic aciduria and variable respiratory chain abnormalities. We wished to determine whether BTHS had a significant impact on fetal and perinatal health in a large cohort of family groups originating from a defined region. METHOD: Case note review on 19 families originating from the UK and known to the Barth Syndrome Service of the Bristol Royal Hospital for Children. RESULTS: Details are presented on six kindreds (32%) with genetically and biochemically proven BTHS that demonstrate a wider phenotype including male fetal loss, stillbirth and severe neonatal illness or death. In these families, 9 males were stillborn and 14 died as neonates or infants but there were no losses of females. BTHS was definitively proven in five males with fetal onset of DCM ± hydrops/EFE/LVNC. CONCLUSION: These findings stress the importance of considering BTHS in the differential diagnosis of unexplained male hydrops, DCM, EFE, LVNC or pregnancy loss, as well as in neonates with hypoglycemia, lactic acidosis and idiopathic mitochondrial disease.

What prevents people with disabilities from obtaining employment? An examination of Canadian data from a national and regional perspective.

People with disabilities who are able to be employed have historically had to struggle with a number of barriers related to workplace activities. In recent years, more data has become available regarding employment in general and for people with disabilities in particular. As major stakeholder groups (people with disabilities, service provider agencies, funders and employers) move to a more integrated and equitable approach, it is essential that data related to employment for people with disabilities not be esoteric but utilitarian. This article will review a Canadian regional study that is being used to help shape vocational services for people with disabilities and will compare the findings to the Canadian national scene.

Diagnostic accuracy of fever as a measure of postoperative pulmonary complications.

Various prevalence rates have been estimated for pulmonary complications after abdominal surgery, and fever has been thought to be a diagnostic indicator. This study quantifies the diagnostic accuracy of fever as a measure of postoperative pulmonary complications and includes the sensitivity, specificity, and positive and negative predictive values. Assessments using fever and chest x-ray film were determined for 270 patients after elective intra-abdominal surgery in three hospitals with six practicing surgeons in a Southern Ontario city. With use of reliable chest x-ray reports indicating lung pathologic findings as positive for pulmonary complication, the prevalence of a positive finding was 57%. The prevalence of a fever (temperature greater than or equal to 38 degrees C) was 40%. The sensitivity and negative predictive value of fever were slightly below 50%, and the specificity and positive predictive value of fever was 68% and 66% respectively. Fever was an accurate indicator of x-ray evidence of atelectasis in only 56% of the subjects. Therefore, neither the presence nor the absence of fever can assure clinicians of the presence or absence of a postoperative pathologic pulmonary complication such as atelectasis.

Psychosocial adjustment of burn survivors.

The purpose of this study was to assess the magnitude and predictors of psychosocial adjustment in burn victims. It was postulated that once individuals sustain a burn, their long-term psychosocial adjustment is a function of their present coping responses, social resources, burn severity and time since burn. It was expected that these variables could also be used to identify individuals at risk for psychosocial maladjustment. A historical cohort analytical survey of 340 randomly selected adults and the mothers of 145 children who had sustained either major or minor burns during the past 12 years were administered the Coping Scale, Participation in Social and Recreational Activities Index, Social Support and the Psychosocial Adjustment to Illness Scale. The children's mothers also completed the Family Environment Scale and the Child Behaviour Checklist. In summary, the variance in psychosocial adjustment among adults was related to unemployment, loss of occupational status, avoidance coping, and little involvement in recreational activities. Together, these variables explained 40 per cent of the variance in psychosocial adjustment. Severity of the burn and time since the burn were not related to psychosocial adjustment. The prevalence of psychosocial maladjustment among the adults was 10 per cent and 15.7 per cent among children. Psychosocial adjustment among children was not related to the severity of the burn. The less adjusted children could be distinguished from adjusted children on the basis of their mothers' adjustment and methods of coping. The findings tended to refute the commonly held view that post-burn adjustment is associated with burn severity and suggests psychosocial adjustment is a function of both coping responses and social resources.

Methodological problems in studies of burn survivors and their psychosocial prognosis.

As the psychological adjustment of burn survivors is a subject of increasing interest, 21 studies on psychosocial adjustment to burns in adults and children are reviewed. These studies are commonly cited as a basis for determining the direction of future research. Eight methodological guidelines are applied to these studies of prognosis. Limitations are identified with the major focus of the paper being to assist in the development of more rigorous methodology in order to promote the optimal rehabilitation for burn survivors.
