Parental Age and Autism Spectrum Disorders Among New York City Children 0-36 Months of Age.

We examined trends in autism spectrum disorders (ASD) and the association of ASD with parental age among young New York City (NYC) children. Children born in NYC to resident mothers from 1994-2001 were identified through vital statistics records (N = 927,003). Records were linked to data from NYC Early Intervention (EI) Program through 2004. The independent parental age-specific odds of having an ASD before 36 months of age were estimated using multiple logistic regression controlling for risk factors. The increase in ASD attributable to changes in parental age at birth was examined. Births to mothers and fathers 35 years or older increased 14.9 and 11.5 %, respectively, between 1994 and 2001. ASD prevalence in EI increased significantly from 1 in 3,300 children born in 1994 to 1 in 233 children born in 2001. Children born to mothers ages 25-29, 30-34 and 35 or older had significantly greater odds of being diagnosed with ASD than children of mothers younger than 25 years (OR 1.5, 1.6, and 1.9, respectively). Children born to fathers ages 35 or older (OR 1.4) had greater odds of ASD than children of fathers younger than 25. The change in parental age accounted for only 2.7 % of the increase in ASD prevalence. Older paternal age and maternal age were independently associated with increased risk of ASD. However, while parental age at birth increased between the 1994 and 2001 birth cohorts in NYC, it did not explain the increase in number of ASD cases.

Illnesses and deaths among persons attending an electronic dance-music festival - New York City, 2013.

Outdoor electronic dance-music festivals (EDMFs) are typically summer events where attendees can dance for hours in hot temperatures. EDMFs have received increased media attention because of their growing popularity and reports of illness among attendees associated with recreational drug use. MDMA (3,4-methylenedioxymethamphetamine) is one of the drugs often used at EDMFs. MDMA causes euphoria and mental stimulation but also can cause serious adverse effects, including hyperthermia, seizures, hyponatremia, rhabdomyolysis, and multiorgan failure. In this report, MDMA and other synthetic drugs commonly used at dance festivals are referred to as "synthetic club drugs." On September 1, 2013, the New York City (NYC) Department of Health and Mental Hygiene (DOHMH) received reports of two deaths of attendees at an EDMF (festival A) held August 31-September 1 in NYC. DOHMH conducted an investigation to identify and characterize adverse events resulting in emergency department (ED) visits among festival A attendees and to determine what drugs were associated with these adverse events. The investigation identified 22 cases of adverse events; nine cases were severe, including two deaths. Twenty-one (95%) of the 22 patients had used drugs or alcohol. Of 17 patients with toxicology testing, MDMA and other compounds were identified, most frequently methylone, in 11 patients. Public health messages and strategies regarding adverse health events might reduce illnesses and deaths at EDMFs.

Reengagement of high-need individuals with serious mental illness after discontinuation of services.

OBJECTIVE: The study determined rates of reengagement in services for individuals with serious mental illness who had discontinued services. METHODS: As part of a quality assurance program in New York City involving continuous review of Medicaid claims and other administrative data, clinician care monitors identified 2,834 individuals with serious mental illness who were apparently in need of care but disengaged from services. The care monitors reviewed monthly updates of Medicaid claims, encouraged outreach from providers who had previously worked with identified individuals, and determined whether individuals had reengaged in services. RESULTS: Reengagement rates over a 12-month follow-up period were low, particularly for individuals who had been incarcerated or for whom no service provider was available to provide outreach. CONCLUSIONS: Subgroups of disengaged individuals with serious mental illness have different rates of reengagement. Active outreach by providers might benefit some, but such targeting is inefficient when the individual cannot be located.

Cycling in the city: an in-depth examination of bicycle lane use in a low-income urban neighborhood.

BACKGROUND: Regular physical activity such as biking can help prevent obesity and chronic disease. Improvements in cycling infrastructure are associated with higher overall cycling rates, but less is known about bike lane utilization in low-income urban neighborhoods. METHODS: During the summer of 2009, 4 Central Brooklyn streets with bicycle lanes were studied using camcorders to record for a total of 40 hours. Video recordings were coded for behaviors and characteristics of cyclists and motorists. An intercept survey (N = 324, 42% participation rate) captured information on cyclist demographics, behaviors, and attitudes. RESULTS: 1282 cyclists were observed on study streets. Cyclists were primarily male (80.0%) and non-White (54.5%). 9.9% of motorists drove in the bike lane and parked vehicles blocked the bike lane for 9.6% of the observational period. Of cyclists surveyed, 69.4% lived locally, 61.3% were normal weight or underweight, and 64.8% met recommended levels of physical activity by cycling 30+ minutes/day on 5+ days of the past week. CONCLUSIONS: Bicycle lanes were used by local residents of a low-income urban neighborhood. Compared with neighborhood residents overall, cyclists reported better health and health behaviors. Enhancing infrastructure that supports active transportation may be effective in reducing health inequities in low-income urban communities.

Determining engagement in services for high-need individuals with serious mental illness.

This study examined whether Medicaid claims and other administrative data could identify high-need individuals with serious mental illness in need of outreach in a large urban setting. A claims-based notification algorithm identified individuals belonging to high-need cohorts who may not be receiving needed services. Reviewers contacted providers who previously served the individuals to confirm whether they were in need of outreach. Over 10,000 individuals set a notification flag over 12-months. Disengagement was confirmed in 55 % of completed reviews, but outreach was initiated for only 30 %. Disengagement and outreach status varied by high-need cohort.

The effect of school dismissal on rates of influenza-like illness in New York City schools during the spring 2009 novel H1N1 outbreak.

BACKGROUND: The effects of individual school dismissal on influenza transmission have not been well studied. During the spring 2009 novel H1N1 outbreak, New York City implemented an individual school dismissal policy intended to limit influenza transmission at schools with high rates of influenza-like illness (ILI). METHODS: Active disease surveillance data collected by the New York City Health Department on rates of ILI in schools were used to evaluate the impact. Sixty-four schools that met the Health Department's criteria for considering dismissal were included in the analysis. Twenty-four schools that met criteria subsequently dismissed all classes for approximately 1 school week. A regression model was fit to these data, estimating the effect of school dismissal on rates of in-school ILI following reconvening, adjusting for potential confounders. RESULTS: The model estimated that, on average, school dismissal reduced the rate of ILI by 7.1% over the entire average outbreak period. However, a large proportion of in-school ILI occurred before dismissal criteria were met. A separate model estimated that school absenteeism rates were not significantly affected by dismissal. CONCLUSION: Results suggest that individual school dismissal could be considered in situations where schools have a disproportionate number of high-risk students or may be unable to implement recommended preventive or infection control measures. Future work should focus on developing more sensitive indicators of early outbreak detection in schools and evaluating the impact of school dismissal on community transmission.

Use of administrative data to identify potential service gaps for individuals with serious mental illness.

OBJECTIVE: The New York City Mental Health Care Monitoring Initiative uses Medicaid claims data to identify individuals with serious mental illness who are experiencing or at risk for gaps in services. In this study the authors assessed whether proposed service use algorithms accurately identified such individuals. METHODS: A random sample of 500 individuals with serious mental illness was identified. Individuals belonged to specific high-need cohorts and met predefined claims-based criteria for potential service gaps. Clinical staff initiated reviews with prior service providers for 230 individuals. RESULTS: Over a two-week period staff completed reviews for 188 cases (88%). In 66 cases (35%) the individual was fully engaged in care; 84 (45%) had a recent episode of disengagement that was appropriately addressed, and 38 (20%) were not receiving adequate services. CONCLUSIONS: The proposed service use algorithms successfully identified high-need individuals with serious mental illness at risk for gaps in services.

Estimated deaths attributable to social factors in the United States.

OBJECTIVES: We estimated the number of deaths attributable to social factors in the United States. METHODS: We conducted a MEDLINE search for all English-language articles published between 1980 and 2007 with estimates of the relation between social factors and adult all-cause mortality. We calculated summary relative risk estimates of mortality, and we obtained and used prevalence estimates for each social factor to calculate the population-attributable fraction for each factor. We then calculated the number of deaths attributable to each social factor in the United States in 2000. RESULTS: Approximately 245,000 deaths in the United States in 2000 were attributable to low education, 176,000 to racial segregation, 162,000 to low social support, 133,000 to individual-level poverty, 119,000 to income inequality, and 39,000 to area-level poverty. CONCLUSIONS: The estimated number of deaths attributable to social factors in the United States is comparable to the number attributed to pathophysiological and behavioral causes. These findings argue for a broader public health conceptualization of the causes of mortality and an expansive policy approach that considers how social factors can be addressed to improve the health of populations.

Public-academic partnerships: using Medicaid claims data to identify service gaps for high-need clients: the NYC Mental Health Care Monitoring Initiative.

Public mental health authorities have access to large administrative databases. Advances in information technology now make it possible to use secondary analyses of these data to inform policy and clinical interventions. New York City and State mental health authorities developed an initiative using Medicaid claims and other administrative data to identify individuals with serious mental illness living in New York City (NYC) who are at risk of lapses in care. The NYC Mental Health Care Monitoring Initiative represents one of the first efforts to create "evidence-based policy." The authors describe the initiative's background, development, and key collaborations.

Public health and environmental response to the first case of naturally acquired inhalational anthrax in the United States in 30 years: infection of a new york city resident who worked with dried animal hides.

In Pennsylvania on February 16, 2006, a New York City resident collapsed with rigors and was hospitalized. On February 21, the Centers for Disease Control and Prevention and the New York City Department of Health and Mental Hygiene were notified that Bacillus anthracis had been identified in the patient's blood. Although the patient's history of working with dried animal hides to make African drums indicated the likelihood of a natural exposure to aerosolized anthrax spores, bioterrorism had to be ruled out first. Ultimately, this case proved to be the first case of naturally occurring inhalational anthrax in 30 years. This article describes the epidemiologic and environmental investigation to identify other cases and persons at risk and to determine the source of exposure and scope of contamination. Because stricter regulation of the importation of animal hides from areas where anthrax is enzootic is difficult, public healthcare officials should consider the possibility of future naturally occurring anthrax cases caused by contaminated hides. Federal protocols are needed to assist in the local response, which should be tempered by our growing understanding of the epidemiology of naturally acquired anthrax. These protocols should include recommended methods for reliable and efficient environmental sample collection and laboratory testing, and environmental risk assessments and remediation.

Breastfeeding ambivalence among low-income African American and Puerto Rican women in north and central Brooklyn.

This study explores low-income African American and Puerto Rican women's conceptions and practices around breastfeeding. It examines the impact of such diverse factors as social constructions of the body, local mores around infant care, the practicalities of food availability, in the context of interactions with family members and friends, institutions, and others in women's neighborhoods. The study employed ethnographic methods, including interviews and participant observation, with 28 families in two low-income Brooklyn neighborhoods. While women in this study felt that breastfeeding was the best way to feed their infants, their commitment turned to ambivalence in the face of their perceptions about the dangers of breast milk, the virtues of formula, and the practical and sociocultural challenges of breastfeeding. Women's ambivalence resulted in a widespread complementary feeding pattern that included breast milk and formula, and resulted in short breastfeeding durations. Findings suggest the critical role of breastfeeding "ambivalence" in driving thought and action in women's lives. Ambivalence erodes the permanence of breastfeeding intention, and makes feeding practices provisional. Ambivalence challenges breastfeeding promotion strategies, resulting in weakened public health messages and a difficult-to-realize public health goal.

Secular changes in mortality disparities in New York City: a reexamination.

Previously published analyses showed that inequalities in mortality rates between residents of poor and wealthy neighborhoods in New York City (NYC) narrowed between 1990 and 2000, but these trends may have been influenced by population in-migration and gentrification. The NYC public housing population has been less subject to these population shifts than those in other NYC neighborhoods. We compared changes in mortality rates (MRs) from 1989-1991 to 1999-2001 among residents of NYC census blocks consisting entirely of public housing residences with residents of nonpublic housing low-income and higher-income blocks. Public housing and nonpublic housing low-income blocks were those in census block groups with > or =50% of residents living at <1.5 times the federal poverty level (FPL); nonpublic housing higher-income blocks were those in census block groups with <50% of residents living at <1.5 times the FPL. Information on deaths was obtained from NYC's vital registry, and US Census data were used for denominators. Age-standardized all-cause MRs in public housing, low-income, and higher-income residents decreased between the decades by 16%, 28%, and 22%, respectively. While mortality rate ratios between low-income and higher-income residents narrowed by 8%, the relative disparity between public housing and low-income residents widened by 21%. Diseases amenable to prevention including malignancies, diabetes, and chronic lung disease contributed to the increased overall mortality disparity between public housing and lower-income residents. These findings temper previous findings that inequalities in the health of poor and wealthier NYC neighborhood residents have narrowed. NYC public housing residents should be a high-priority population for efforts to reduce health disparities.

The syringe gap: an assessment of sterile syringe need and acquisition among syringe exchange program participants in New York City.

BACKGROUND: Programmatic data from New York City syringe exchange programs suggest that many clients visit the programs infrequently and take few syringes per transaction, while separate survey data from individuals using these programs indicate that frequent injecting - at least daily - is common. Together, these data suggest a possible "syringe gap" between the number of injections performed by users and the number of syringes they are receiving from programs for those injections. METHODS: We surveyed a convenience sample of 478 injecting drug users in New York City at syringe exchange programs to determine whether program syringe coverage was adequate to support safer injecting practices in this group. RESULTS: Respondents reported injecting a median of 60 times per month, visiting the syringe exchange program a median of 4 times per month, and obtaining a median of 10 syringes per transaction; more than one in four reported reusing syringes. Fifty-four percent of participants reported receiving fewer syringes than their number of injections per month. Receiving an inadequate number of syringes was more frequently reported by younger and homeless injectors, and by those who reported public injecting in the past month. CONCLUSION: To improve syringe coverage and reduce syringe sharing, programs should target younger and homeless drug users, adopt non-restrictive syringe uptake policies, and establish better relationships with law enforcement and homeless services. The potential for safe injecting facilities should be explored, to address the prevalence of public injecting and resolve the 'syringe gap' for injecting drug users.
