Studies of socioeconomic gradients in mortality in wealthy societies reveal that they have been persist, and included most of the principal causes of death, even during the era when these principal causes of death have entirely changed. This observation has led to an interest in the ways in which the diversity of conditions of life, unfolding over the life cycle, can become embedded in human biology and subsequently affect health status and vitality. There is evidence that childhood experiences affect subsequent health status (as well as well-being and competence) in profound and long-lasting ways. Conflicting explanatory models of the impact of childhood experiences have been advanced, whose conflicts are political in nature, in that the reflect divergent beliefs about how human potential expresses itself, and, also, about the nature of the obligations which members of society have to one another. Notwithstanding these conflicts, a body of evidence derived from intervention studies in the post-neonatal, preschool, and school age periods suggest that performance in two basic domains of child development, the cognitive and the social-emotional, can be modified in ways which improve health, well-being, and competence in the long-term.

Literature databases were scanned to locate articles pertaining to food handler education and restaurant inspection. Papers which met pre-established criteria, as described in the generic protocol produced by the Community Health Practice Guidelines Project (CHPG), were evaluated by standardized consideration of criteria. Studies were rated on a scale of one to three. There were eight papers related to the intervention of education, four papers dealing with the intervention of restaurant inspection, and one pertaining to both. the evidence presented in the papers regarding the effectiveness of food handler training in improving food establishment sanitation was weak, but it appeared that some training resulted in improved inspection scores. It appeared that inspections were beneficial, although it was not clear whether three or more inspections were better than two. No inspections appeared to result in worse inspection scores.

Recently, many British Columbia sawmills stopped using traditional chlorophenate anti-sapstain fungicides and substituted 2-(thiocyanomethylthio) benzothiazole (TCMTB) and copper-8-quinolinolate (Copper 8). We conducted a cross-sectional study with two aims: to ascertain which acute health effects, if any, were associated with the use of the substitute fungicides; and to determine the effectiveness of first-aid records as a means of detecting acute health outcomes. Workers in five coastal sawmills were asked to complete a self-administered questionnaire about symptoms considered potentially related and unrelated to fungicide exposure, and about injuries commonly reported in sawmills. In addition, we collected first-aid records from the mills, and asked senior workers to estimate the duration of exposure to fungicides for each job. Symptoms found to be consistently elevated in TCMTB mills included dry skin around the eyes, blood-stained mucus from the nose, nose bleed, peeling skin, burning or itching skin, and skin redness or rash. No symptoms were consistently elevated in the Copper 8 mills. Symptoms related to TCMTB exposure were recorded only 12 times in first-aid logs during the study period (versus 335 questionnaire self-reports). This low symptom-recording frequency may be a function of established patterns of first-aid use in which illness symptoms are reported less frequently than injuries.

We compared personal histories of 57 cases and 122 age-matched controls to identify possible environmental determinants of Parkinson's disease (PD). Odds ratios (OR) adjusted for sex, age, and smoking were computed using stepwise logistic regression. We found a statistically significant increased risk for working in orchards (OR = 3.69, p = 0.012, 95% CI = 1.34, 10.27) and a marginally significant increased risk associated with working in planer mills (OR = 4.11, p = 0.065, 95% CI = 0.91, 18.50). A Fisher's exact test of the association between PD development and (1) paraquat contact, and (2) postural tremor gave statistically significant probability estimates of 0.01 and 0.03, respectively. The relative risk of PD decreased with smoking, an inverse relationship supported by many studies.
