1.0. INTRODUCTION
The health of those living and working in a city is influenced by many factors: the physical, social, and economic environment; access to quality medical care; avail- ability of lucid, understandable health information; presence of programs that promote health; and adoption, by individuals, of healthy behaviors. While these factors deserve consideration in any locale, urban or otherwise, they present con- siderable challenges for the urban public health practitioner. Deteriorating hous- ing stock in older, urban neighborhoods – with its concomitant peeling paint and pest infestations – has implications for lead poisoning control and asthma man- agement (Leighton, et al., 2003; Rosenstreich, et al., 1997). The relative dearth of outdoor recreation areas and the perception that urban parks are unsafe discour- age physical activity (Estabrooks, et al., 2003; Parks, et al., 2003), and thus may be associated with greater risk of disease. The clustering of new immigrant popula- tions in urban areas presents language and cultural challenges that affect health care deliver y and health education efforts (Kandula, et al., 2004). And poverty itself – a defining characteristic of vulnerable urban populations (Geronimus, 2000) – is strongly associated with decreased life expectancy (Lin, et al., 2003;
Wong, et al., 2002). Strategies that promote health in cities must consider these and other variables to succeed.
This chapter’s focus is the role of a municipal health department in setting and implementing an urban health agenda, specifically drawing on the experi- ences and approach of the New York City Department of Health and Mental Hygiene (DOHMH). Several relevant DOHMH health promotion efforts are also described.

2.0. SETTING THE AGENDA: THE ROLE OF THE MUNICIPAL HEALTH DEPARTMENT.
While acute, communicable diseases once accounted for most illness and death in the U.S., today’s leading public health concerns are largely chronic and noncommunicable.
As a result, the roles of health departments nationwide are shifting – albeit slowly.
While still responsible for such traditional public health functions as investigating outbreaks, disease surveillance, diagnosing and treating tuberculosis and sexually transmitted diseases, and enforcing laws and regulations that protect health and ensure safety, health agencies are now confronted with the need to develop and implement an agenda responsive to the current burden of disease. Reasons for the slow embrace of a chronic disease action plan are many: (1) chronic diseases do not present as crises, and given their long latency periods, it is difficult to generate enthusiasm for interventions with few short-term impacts; (2) the public is more concerned about involuntary (e.g., living next to a hazardous waste site) than what are perceived as voluntary (e.g., smoking) risks; (3) many local health agencies do not have chronic disease and risk factor surveillance systems necessary for identify- ing priorities and evaluating interventions; and (4) insufficient resources have been made available for chronic disease prevention efforts (Brownson, et al., 2004).
In recent years, the DOHMH has intensified its efforts to create and set into motion an urban health agenda responsive to the needs and concerns of the city’s residents – a large component of which is devoted to chronic disease prevention and control activities. Below we discuss the steps taken and factors considered in developing and implementing this agenda.
2.1. Identify Public Health Needs and Affected Populations
New York City’s health agenda is a response to the burden of disease of its populace.
Priority setting is data driven, informed by morbidity, mortality and risk factor data – and complemented by community perceptions about health and causes of disease.
In New York City, a unique data source is the Community Health Survey, a neigh- borhood-level adaptation and enhancement of the Behavioral Risk Factor Surveillance System (BRFSS), which has been conducted annually since 2002. The distribution of disease and risk factors for disease also shapes the agenda, with resources directed at communities and population groups disproportionately affected. In developing an action plan, emphasis has been placed on high-burden conditions that are amenable to prevention efforts, i.e., those health problems for which evidence-based interventions exist.
As an example of how data can inform the establishment of public health pri- orities, consider New York City mortality data. Cardiovascular disease, followed by cancer, are the city’s leading killers, accounting for, respectively, 41.1% and 23.0%
of all deaths in 2002. Many of these deaths can be directly attributed to cigarette
smoking, which kills approximately 10,000 New Yorkers per year, making it the
leading preventable cause of death. A further examination of these mortality data
reveals, for example, that for both heart disease and colon cancer, black New
Yorkers die at younger ages than white New Yorkers (Figure 1, Figure 2), which
may indicate missed opportunities for prevention, early detection and treatment
among blacks. Similar patterns can be detected when examining another leading
cause of death among New Yorkers – HIV/AIDS. While mortality rates have been
declining over time, differences among racial/ethnic and income groups exist

(Figure 3), with blacks and those living in very low-income neighborhoods most likely to die from AIDS – perhaps reflecting differential access to life-prolonging medical treatment (Karpati, et al., 2004). Data such as these help establish priori- ties, determine inter vention strategies and identify populations and neighbor- hoods to be targeted.
2.2. Promote Evidence-Based Interventions
Tackling priority health concerns requires an appreciation of the conditions that underlie them. For example, an examination of “actual” causes of death, i.e., exter- nal, modifiable factors that contribute to death, reveals that, in 2000, approximately half of all deaths in the U.S. could be attributed to largely preventable behaviors and exposures; heading the list were tobacco and poor diet/physical inactivity, accounting for 18.1% and 16.6% of all deaths nationwide, respectively (Mokdad, et al., 2004). Thus, if the public health community hopes to have an impact on pre- ventable deaths, effective interventions to address tobacco use, physical inactivity and poor diet are needed.
The Task Force on Community Preventive Ser vices—a non-federal, inde-
pendent panel of experts convened by the Centers for Disease Control and
Prevention—is systematically reviewing the scientific literature to identify
community interventions that are effective in promoting health and preventing
disease (Truman, et al., 2000). The product of this undertaking, The Community
Guide to Preventive Services, found at www.thecommunityguide.org is a valuable
resource to local health agencies engaged in developing health agendas and corre-
sponding action plans. The DOHMH often consults the Community Guide, and its
recommendations have been incorporated into community program planning
efforts – resulting, for example, in enhanced physical activity programs in New
York City schools and parks in at-risk communities and increased school-based den-
tal sealant activities.
2.3. Promote Coordination of Services
For an intervention to be successful, a coordinated effort is often required. In large urban areas where coordination can be complex, health departments can play an important convening role. Additionally, local health agencies need to look within and identify internal obstacles to providing a coordinated effort. Development and maintenance of an organizational culture that encourages cooperation and collabo- ration across programs is key (Brownson, et al., 2004).
2.4. Foster Diverse Partnerships
Closely linked with coordinating services is the need to engage a diverse array of organizations – including community-based and nonprofit organizations, health care providers, faith-based organizations, businesses, unions, media, and local and state government – in the development and launch of often large, multi-faceted interventions. Involvement of many sectors of the community is believed to increase the likelihood of success for collaborative efforts (Israel, et al., 2001). Also critical to the success of a partnership and the project it spearheads are a clearly articulated mission, strong leadership, a well-conceived action plan, and good communication (Kegler, et al., 1998). Again, health departments – which often are experienced in coalition building and in working with communities to address health concerns – can assume a central role in fostering such partnerships and providing leadership;
such a role is recommended by the National Public Health Performance Standards Program, a collaborative, CDC-initiated effort that has created performance stan- dards for local public health systems found at www.phppo.cdc.gov/nphpsp.
2.5. Advocate for Broader Social and Economic Change
In the pursuit of population-wide health, there are many social and economic forces to be addressed, many of which are not within the exclusive purview of the local health department. Still, health departments can be important advocates for change. By arming communities with health data and facilitating community dia- logue, local health systems can influence policy development, enabling informed
