Toward a smoke-free Harlem: engaging families, agencies, and community-based programs

The aim of this collaborative public health study was to engage families, agencies, and programs in reducing secondhand smoke exposure in Central Harlem, New York City. Baseline interviews (n=657) and focus groups (n=4) were conducted with adult members of households with children who had asthma and asthma-like symptoms in the Harlem Children's Zone Asthma Initiative. The interviews concerned the prevalence and determinants of exposure of enrolled children to secondhand smoke. Key findings were that participants: (1) were generally aware of the hazards of secondhand smoke; (2) used strategies to reduce exposure to secondhand smoke in their homes; (3) believed that outdoor pollutants are sometimes just as bad for the health of their children as secondhand smoke; and (4) used smoking to provide stress relief and help diffuse otherwise volatile situations in their homes. The Harlem Smoke-Free Home Campaign was launched in October 2007 based in part on these findings

Global Tobacco Control: An integrated approach to global health policy

Following the development discussion in the last volume on the ‘politics of health’, Jennifer Prah Ruger argues that the Framework Convention on Tobacco Control (FCTC) represents a shift in global health policy that recognizes the importance of addressing health needs on multiple fronts and integrating public policies into a comprehensive set of health improvement strategies. She argues that the FCTC provides a model for multifaceted approaches to health improvement that require simultaneous progress on various dimensions.

Importance of biological parameters in assessing the status of Delphinus delphis

Short-beaked common dolphins Delphinus delphis in the eastern North Atlantic (ENA) are subject to mortality due to entanglement in various types of fishing gear. However, for this region, there is no population-level information available on trends in abundance, (incidental) mortality rates or even the actual distributional range. Working under the assumption that only 1 population exists in ENA waters, the current study presents basic life history data and investigates whether biological information obtained from postmortem data is, in itself, useful for managing this population. Life history parameters were estimated by analysing postmortem data obtained over a 16 yr period by UK, Irish, French, Galician (northwest Spain) and Portuguese stranding and bycatch observer programmes. An annual pregnancy rate of 26%, a calving interval of 3.79 yr, an average age attained at sexual maturity of 8.22 yr and an average length at sexual maturity of 188 cm were determined. With respect to the findings based solely on mortality data, significance testing failed to detect differences that could be construed as evidence of the population exhibiting what might be density-dependent compensatory responses. The low annual pregnancy rate reported throughout the sampling period may suggest either that the level of anthropogenic mortality did not cause a substantial population level decline, or a prey base declining at approximately the same rate as the dolphin population. However, this approach alone does not facilitate an assessment of the current state of the D. delphis population in the ENA. Population abundance estimates, trends in abundance and knowledge of factors that affect the dynamics of the population, such as annual mortality rates in fisheries, temporal variations in prey abundance and effects of contaminants on reproductive activity, are required not only to set management objectives, but also to give context to cross-sectional life history information
