Physical inactivity is a leading cause of death in the United States and globally and is also associated with several additional leading causes of death, including obesity, high blood pressure and high blood glucose. The built environment plays a critical role in promoting or discouraging physical activity among adults and children. To create a healthier and more physically active city, a working group comprising several New York City agencies, including the Departments of Design and Construction, Health and Mental Hygiene, Transportation and City Planning, and in collaboration with design organizations and academics, published the Active Design Guidelines (ADG; 〈www.nyc.gov/adg〉) in January 2010. The ADG is a manual of evidence-based and best-practice strategies for increasing physical activity in the design and construction of neighborhoods, streets and buildings. The commentary discusses key activities and events leading up to the publication as well as current implementation activities. It also shares the lessons learned that could assist other communities interested in improving their built environments in developing and implementing similar activities and initiatives. © 2011.

BACKGROUND: Early sex is associated with high-risk behaviors and outcomes, including sexual risk behaviors, forced sex, physical dating violence, and becoming pregnant or impregnating someone. METHODS: Using 2005 and 2007 data from the New York City Youth Risk Behavior Survey (N=17,220), this study examined the prevalence of early sex among public high school students; associations between early sex and other sexual risk factors and violence indicators; and whether associations varied across 4 racial/ethnic groups. Bivariate and multiple logistic regression models estimated the relationship between sexual risk and violence outcomes and "early sex," defined as first having sexual intercourse before age 14. Separate models with an interaction term for early sex by race/ethnicity were also estimated. RESULTS: More than one third of students who ever had sex reported having early sex. Adolescents reporting early sex were significantly more likely than those reporting later sex to engage in most sexual risk behaviors and to experience violence. The magnitude of association varied significantly by race/ethnicity for sexual risk behaviors. CONCLUSIONS: The high prevalence of early sex, coupled with its associated high-risk behaviors and outcomes, underscores the necessity of implementing evidence-based interventions that have been found to positively impact these behaviors beginning in middle school. © 2013, American School Health Association.

Tobacco control | Year: 2013
To increase knowledge of smoking-related health risks and provide smoking cessation information at the point of sale, in 2009, New York City required the posting of graphic point-of-sale tobacco health warnings in tobacco retailers. This study is the first to evaluate the impact of such a policy in the USA. Cross-sectional street-intercept surveys conducted among adult current smokers and recent quitters before and after signage implementation assessed the awareness and impact of the signs. Approximately 10 street-intercept surveys were conducted at each of 50 tobacco retailers in New York City before and after policy implementation. A total of 1007 adults who were either current smokers or recent quitters were surveyed about the awareness and impact of tobacco health warning signs. Multivariate risk ratios (RR) were calculated to estimate awareness and impact of the signs. Most participants (86%) were current smokers, and the sample was 28% African-American, 32% Hispanic/Latino and 27% non-Hispanic white. Awareness of tobacco health warning signs more than doubled after the policy implementation (adjusted RR =2.01, 95% CI 1.74 to 2.33). Signage posting was associated with an 11% increase in the extent to which signs made respondents think about quitting smoking (adjusted RR =1.11, 95% CI 1.01 to 1.22). A policy requiring tobacco retailers to display graphic health warning signs increased awareness of health risks of smoking and stimulated thoughts about quitting smoking. Additional research aimed at evaluating the effect of tobacco control measures in the retail environment is necessary to provide further rationale for implementing these changes.

Objective The birth certificate variable obstetric estimate of gestational age (GA) has not been previously validated against GA based on estimated date of delivery from medical records. Study Design We estimated sensitivity, specificity, positive predictive value, negative predictive value and the corresponding 95% confidence intervals (CIs) for preterm delivery (<37 weeks' gestation) based on obstetric estimate using estimated date of delivery-based GA as the gold standard. Trained abstractors obtained the estimated date of delivery from the prenatal record (64.8% in New York City, and 94.6% in Vermont), or, when not available, from the hospital delivery record for 2 population-based samples: 586 live births delivered in New York City and 649 live births delivered in Vermont during 2009. Weights were applied to account for nonresponse and sampling design. Results In New York City, the preterm delivery rate based on estimated date of delivery was 9.7% (95% CI, 7.6-12.4) and 8.2% (95% CI, 6.3-10.6) based on obstetric estimate; in Vermont, it was 6.8% (95% CI, 5.4-8.4) based on estimated date of delivery and 6.3% (95% CI, 5.1-7.8) based on obstetric estimate. In New York City, sensitivity of obstetric estimate-based preterm delivery was 82.5% (95% CI, 69.4-90.8), specificity 98.1% (95% CI, 96.4-99.1), positive predictive value 98.0% (95% CI, 95.2-99.2), and negative predictive value 98.8% (95% CI, 99.6-99.9). In Vermont, sensitivity of obstetric estimate-based preterm delivery was 93.8% (95% CI, 81.8-98.1), specificity 99.6% (95% CI, 98.5-99.9), positive predictive value 100%, and negative predictive value 100%. Conclusion Obstetric estimate-based preterm delivery had excellent specificity, positive predictive value and negative predictive value. Sensitivity was moderate in New York City and excellent in Vermont. These results suggest obstetric estimate-based preterm delivery from the birth certificate is useful for the surveillance of preterm delivery. © 2014 Mosby, Inc. All rights reserved.

Background: Dietary trans fat increases risk for coronary heart disease. In 2006, New York City (NYC) passed the first regulation in the United States restricting trans fat use in restaurants. Objective: To assess the effect of the NYC regulation on the trans and saturated fat content of fast-food purchases. Design: Cross-sectional study that included purchase receipts matched to available nutritional information and brief surveys of adult lunchtime restaurant customers conducted in 2007 and 2009, before and after implementation of the regulation. Setting: 168 randomly selected NYC restaurant locations of 11 fast-food chains. Participants: Adult restaurant customers interviewed in 2007 and 2009. Measurements: Change in mean grams of trans fat, saturated fat, trans plus saturated fat, and trans fat per 1000 kcal per purchase, overall and by chain type. Results: The final sample included 6969 purchases in 2007 and 7885 purchases in 2009. Overall, mean trans fat per purchase decreased by 2.4 g (95% CI, -2.8 to -2.0 g; P < 0.001), whereas saturated fat showed a slight increase of 0.55 g (CI, 0.1 to 1.0 g; P = 0.011). Mean trans plus saturated fat content decreased by 1.9 g overall (CI, -2.5 to -1.2 g; P < 0.001). Mean trans fat per 1000 kcal decreased by 2.7 g per 1000 kcal (CI, -3.1 to -2.3 gper 1000 kcal; P < 0.001). Purchases with zero grams of trans fat increased from 32% to 59%. In a multivariate analysis, the poverty rate of the neighborhood in which the restaurant was located was not associated with changes. Limitation: Fast-food restaurants that were included may not be representative of all NYC restaurants. Conclusion: The introduction of a local restaurant regulation was associated with a substantial and statistically significant decrease in the trans fat content of purchases at fast-food chains, without a commensurate increase in saturated fat. Restaurant patrons from high- and low-poverty neighborhoods benefited equally. However, federal regulation will be necessary to fully eliminate population exposure to industrial trans fat sources.
