Association of child and adolescent psychiatric disorders with somatic or biomedical diagnoses: do population-based utilization study results support the adverse childhood experiences study?

Context: Few population-based studies have examined the relationship between psychiatric and somatic or biomedical disorders.

Objective: We examined the effect of the presence or absence of any psychiatric disorder on somatic or biomedical diagnosis disorder costs. Guided by the Kaiser Permanente and Centers for Disease Control and Prevention Adverse Childhood Experiences (ACE) Study, we examined our administrative data to test if psychiatric disorder is associated with a higher level of somatic disorder.

Association of mental health with health care use and cost: a population study.

Objective: To compare the health costs of groups with and without psychiatric diagnoses (PDs) using 9 years of physician billing data.

Methods: A dataset containing registration data for all patients receiving public mental health service was constructed and subsequently matched, on age and sex, in a final patient to comparison patient ratio of 1:8, with health care users who did not receive treatment in the mental health system. Three groups emerged: a patient PD group-patients with psychiatric disorders treated in public mental health care (n = 76 677); a comparison patient PD group-comparison patients with PDs treated in physicians only (n = 277 627); and a patient- comparison patient non-PD group-patients (treated in specialized publicly funded care or by their physician) without PDs (n = 329 177).

Spatial mapping of lead, arsenic, iron, and polycyclic aromatic hydrocarbon soil contamination in Sydney, Nova Scotia: community impact from the coke ovens and steel plant.

This paper presents spatial maps of the arsenic, lead, and polycyclic aromatic hydrocarbon (PAH) soil contamination in Sydney, Nova Scotia, Canada. The spatial maps were designed to create exposure cohorts to help understand the observed increase in health effects. To assess whether contamination can be a proxy for exposures, the following hypothesis was tested: residential soils were impacted by the coke oven and steel plant industrial complex.

Development of local knowledge of environmental contamination in Sydney, Nova Scotia: environmental health practice from an environmental justice perspective.

In Sydney, Nova Scotia, from 1901 through 1988 a coke and steel factory operated with no pollution controls, depositing over a million tons of particulate matter and releasing several thousands of tons of coal tar into the estuary. Previously we documented the presence of lead, arsenic and PAHs, in soil above Canadian guidelines, and in house dust in the communities surrounding the site [Lambert, TW, Lane, S. Lead, arsenic, and polycyclic aromatic hydrocarbons in soil and house dust in the communities surrounding the Sydney, Nova Scotia, tar ponds.
