Temporal trends in overweight and obesity in Canada, 1981-1996.

Abstract: OBJECTIVE: To assess changes in the prevalence of overweight and obesity among Canadian children and adults between 1981 and 1996 using recent recommendations for the classification of overweight and obesity. DESIGN: Epidemiological study comparing the prevalence of overweight and obesity from the 1981 Canada Fitness Survey (CFS) to the 1996 National Longitudinal Survey of Children and Youth (NLSCY) and the 1996 National Population Health Survey (NPHS). SUBJECTS: Adults 20–64 y of age and children 7–13 y of age from the CFS, NLSCY and NPHS. MEASUREMENTS: BMI was calculated from directly measured or self-reported body mass and height. For adults 20–64 y of age, overweight and obesity were defined as BMI≥25 kg/m2 and BMI≥30 kg/m2, respectively. Age- and sex-specific cut-off points for children that correspond to the adulthood categories were used to define overweight and obesity for children 7–13 y of age. RESULTS: The prevalence of overweight increased from 48 to 57% among men and from 30 to 35% among women, while the prevalence of obesity increased from 9 to 14% in men and from 8 to 12% in women. The corresponding increases were from 11 to 33% in boys and from 13 to 27% in girls for overweight and from 2 to 10% in boys and from 2 to 9% in girls for obesity. CONCLUSION: The results indicate dramatic increases in the prevalence of both overweight and obesity in Canada over the last 15 y, and the problem is particularly pronounced among children.

H2S-induced vasorelaxation and underlying cellular and molecular mechanisms

Abstract: H2S is endogenously generated in vascular smooth muscle cells. The signal transduction pathways involved in the vascular effects of H2S have been unclear and were investigated in the present study....

Establishment of stable, cell-mediated immunity that makes "susceptible" mice resistant to Leishmania major.

Abstract: Cell-mediated, but not antibody-mediated, immune responses protect humans against certain pathogens that produce chronic diseases such as leishmaniasis. Effective vaccination against such pathogens must therefore produce an immunological "imprint" so that stable, cell-mediated immunity is induced in all individuals after natural infection. BALB/c mice "innately susceptible" to Leishmania major produce antibodies after substantial infection. In the present study, "susceptible" mice injected with a small number of parasites mounted a cell-mediated response and acquired resistance to a larger, normally pathogenic, challenge. This vaccination strategy may be applicable in diseases in which protection is dependent on cell-mediated immunity.

Why Are Job Seekers Attracted by Corporate Social Performance? Experimental and Field Tests of Three Signal-Based Mechanisms

Abstract: Research on employee recruitment has shown that an organization's corporate social performance (CSP) affects its attractiveness as an employer, but the underlying mechanisms and processes through which this occurs are poorly understood. We propose that job seekers receive signals from CSP that inform three signal-based mechanisms that ultimately affect organizational attractiveness: job seekers' anticipated pride from being affiliated with the organization, their perceived value fit with the organization, and their expectations about how the organization treats its employees. We hypothesized that these signal-based mechanisms mediate the relationships between CSP and organizational attractiveness, focusing on two aspects of CSP: an organization's community involvement and pro-environmental practices. In an experiment (n 180), we manipulated CSP via a company's web pages. In a field study (n 171), we measured CSP content in the recruitment materials used by organizations at a job fair and job seekers' perceptions of the organizations' CSP. Results provided support for the signal-based mechanisms, and we discuss the implications for theory, future research, and practice
