Common state mechanisms regulating tribal tobacco taxation and sales, the USA, 2015

Background Native American tribes, as sovereign nations, are exempt from state tobacco excise taxation, and self-govern on-reservation activity in the USA. Under Federal law, state excise taxes are owed by non-members purchasing tobacco on tribal land, but states are limited in how they enforce or collect these taxes. This study highlights the various policy approaches that states have taken to regulate tobacco sales on tribal lands given jurisdictional challenges. Methods State laws (statutes, regulations and case law), Attorney General opinions, and revenue notices and rulings effective as of 1 January 2015 for all 50 states and the District of Columbia were compiled using Boolean searches in Lexis-Nexis and Westlaw. Laws were limited to those addressing taxation compacts or tobacco sales involving tribal entities. Master Settlement Agreement laws and non-codified tribal codes/compacts were excluded. Results Twenty of the 34 states with tribal lands address tribal tobacco sales. Fourteen states address intergovernmental compacts: 11 are tobacco specific, and suggest or require specific provisions. Fifteen states address tribal tax stamps: 2 explicitly prohibit stamping tribally sold products, 9 stamp all products, and 4 stamp some. Prepayment of excise tax is required in 12 states: 6 on all products, 4 on products in excess of quota, and 2 on products sold by non-tribal retailers. 6 states use quotas to limit tax-free tobacco available to tribes. Conclusions Many states with a tribal presence have no formal strategies for non-members purchasing tobacco on tribal lands. Formalising policies and harmonising tax rates may assist states in collecting tax revenue from non-tribal consumers.

Communities on the Move: Pedestrian-Oriented Zoning as a Facilitator of Adult Active Travel to Work in the United States

Background Communities across the United States have been reforming their zoning codes to create pedestrian-friendly neighborhoods with increased street connectivity, mixed use and higher density, open space, transportation infrastructure, and a traditional neighborhood structure. Zoning code reforms include new urbanist zoning such as the SmartCode, form-based codes, transects, transportation and pedestrian-oriented developments, and traditional neighborhood developments. Purpose To examine the relationship of zoning code reforms and more active living-oriented zoning provisions with adult active travel to work via walking, biking, or by using public transit. Methods Zoning codes effective as of 2010 were compiled for 3,914 municipal-level jurisdictions located in 471 counties and 2 consolidated cities in 48 states and the District of Columbia, and that collectively covered 72.9% of the U.S. population. Zoning codes were evaluated for the presence of code reform zoning and nine pedestrian-oriented zoning provisions (1 = yes): sidewalks, crosswalks, bike-pedestrian connectivity, street connectivity, bike lanes, bike parking, bike-pedestrian trails/paths, mixed-use development, and other walkability/pedestrian orientation. A zoning scale reflected the number of provisions addressed (out of 10). Five continuous outcome measures were constructed using 2010–2014 American Community Survey municipal-level 5-year estimates to assess the percentage of workers: walking, biking, walking or biking, or taking public transit to work OR engaged in any active travel to work. Regression models controlled for municipal-level socioeconomic characteristics and a GIS-constructed walkability scale and were clustered on county with robust standard errors. Results Adjusted models indicated that several pedestrian-oriented zoning provisions were statistically associated (p < 0.05 or lower) with increased rates of walking, biking, or engaging in any active travel (walking, biking, or any active travel) to work: code reform zoning, bike parking (street furniture), bike lanes, bike-pedestrian trails/paths, other walkability, mixed-use zoning, and a higher score on the zoning scale. Public transit use was associated with code reform zoning and a number of zoning measures in Southern jurisdictions but not in non-Southern jurisdictions. Conclusion As jurisdictions revisit their zoning and land use policies, they may want to evaluate the pedestrian-orientation of their zoning codes so that they can plan for pedestrian improvements that will help to encourage active travel to work.

More active living-oriented county and municipal zoning is associated with increased adult leisure time physical activity--United States, 2011

Although zoning is recognized for its role in facilitating healthy communities, no study has examined whether active living–oriented zoning codes are associated with adult leisure time physical activity (PA). This study sought to fill this gap and hypothesized that adult leisure time PA would be greater in communities with more progressive zoning code reforms and more active living–oriented zoning. Zoning codes for 1,617 county and municipal jurisdictions located in 30 states (covering ~40% of the U.S. population) were evaluated for code reform zoning and 11 active living markers. County-aggregated zoning measures were created for linking with five adult PA behaviors obtained from the 2011 Behavioral Risk Factor Surveillance System controlling for individual and county sociodemographics. Zoning elements most associated with adult PA included requirements for mixed use, active and passive recreation, bike parking/street furniture, and bike-pedestrian trails/paths. This study provides new insights into the role that zoning can play in facilitating adult PA.

Associations between active living-oriented zoning and no adult leisure-time physical activity in the U.S.

Nearly one-third of adults report no leisure-time physical activity (LTPA). Governmental and authoritative bodies recognize the role that community design through zoning code changes can play in enabling LTPA. This study examined the association between zoning and no adult LTPA in the U.S. This study was conducted between 2012 and 2016, with analyses occurring in 2015-2016. Zoning codes effective as of 2010 were compiled for jurisdictions located in the 495 most populous U.S. counties and were evaluated for pedestrian-oriented code reform zoning, 11 active living-oriented provisions (e.g., sidewalks, bike-pedestrian connectivity, mixed use, bike lanes) and a summated zoning scale (max=12). Individual-level LTPA data were obtained from the 2012 CDC Behavioral Risk Factor Surveillance System (BRFSS). County-aggregated, population-weighted zoning variables were constructed for linking to BRFSS. Log-log multivariate regressions (N=147,517 adults), controlling for individual and county characteristics and with robust standard errors clustered on county, were conducted to examine associations between zoning and no LTPA. Relative risks (RR) compared predicted lack of LTPA at 0% and 100% county-level population exposure to each zoning predictor. Zoning code reforms were associated with a 13% lower probability of no LTPA (RR: 0.87, 95% CI: 0.82-0.92). Except for crosswalks, all zoning provisions were associated with an 11-16% lower probability of no LTPA. Having all 12 zoning provisions was associated with a 22% lower probability of no LTPA (RR: 0.78, 95% CI: 0.72-0.83). The results suggest that active living-oriented zoning is a policy lever available to communities seeking to reduce rates of no LTPA.

Exploring the cross-sectional association between transit-oriented development zoning and active travel and transit usage in the United States, 2010-2014

Background In response to traditional zoning codes that contribute to car-dependent sprawling and disconnected neighborhoods, communities are reforming their land use laws to create pedestrian-friendly areas that promote physical activity. One such reform is the adoption of transit-oriented developments or districts (TODs). TODs are higher density, compact, and mixed use areas located around transit stops that are designed to encourage walking. Purpose To identify the characteristics of communities that have adopted TODs in their land use laws and examine if communities that have included TODs in their zoning codes are more likely to have adults that commute by any form of active transportation (i.e., walking, biking, or public transportation) or by using public transportation specifically. Methods Zoning codes effective as of 2010 were obtained for a purposeful sample of the largest 3,914 municipal jurisdictions located in 473 of the most populous U.S. counties and consolidated cities within 48 states and the District of Columbia. They were evaluated to determine whether they included TOD districts or regulations using a coding tool developed by the study team. Descriptive statistics together with t-tests and Pearson’s chi-squared independence test were used to compare characteristics of jurisdictions with and without TOD zoning. Multivariate linear regressions were used to compute the adjusted association between TOD zoning and taking public or active transportation to work. Results Jurisdictions with TOD zoning were located more in the South and West than non-TOD jurisdictions and were more populous, higher income, more racially diverse, and younger. Jurisdictions with TOD zoning had significantly higher percentages of occupied housing with no vehicle than those without TOD zoning. TOD zoning was associated with significantly higher rates of public transportation to work (β = 2.10, 95% CI = 0.88, 3.32) and active transportation to work (β = 2.48, 95% CI = 1.03, 3.94). Conclusion Communities that have or are considering developing public transit infrastructure may want to modify their zoning codes to include TODs to promote physical activity and active travel to work.

A Quantile Regression Study of Climate Change in Chicago, 1960-2010

This study uses quantile regression combined with time series methods to analyze change in temperatures in Chicago during the period 1960-2010. It builds on previous work in applying quantile regression methods to climate data by Timofeev and Sterin (2010) and work by the Chicago Climate Task Force on analyzing climate change in Chicago. Data from the Chicago O’Hare Airport weather station archived by the National Climatic Data Center are used to look at changes in weekly average temperatures. The method described by Xiao et al. (2003) is used to remove autocorrelation in the data, together with the rank-score method with IID assumption to calculate confidence intervals, and nonparametric local linear quantile regression to estimate temperature trends. The results of this analysis indicate that the decade 1960-1969 was significantly colder than later decades around the middle of the yearly seasonal cycle at both the median and 95th percentile of the temperature distribution. This analysis does not find a statistically significant trend over the later decades, 1970-2010.

Pedestrian-oriented zoning is associated with reduced income and poverty disparities in adult active travel to work, United States

Active travel to work can provide additional minutes of daily physical activity. While the literature points to the relationship between zoning, equity and socioeconomic status, and physical activity, no study has quantitatively explored these connections. This study examined whether zoning may help to moderate any income and poverty inequities in active travel and taking public transit to work. Research was conducted between May 2012 and June 2015. Zoning data were compiled for 3914 jurisdictions covering 45.45% of the U.S. population located in 471 of the most populous U.S. counties and 2 consolidated cities located in 48 states and the District of Columbia. (Sensitivity analyses also captured unincorporated areas which, with the municipalities, collectively covered ~72% of the U.S. POPULATION ) Zoning codes were obtained and evaluated to assess the pedestrian-orientation of the zoning codes. Public transit use, active travel to work, median household income, and poverty data were obtained for all study jurisdictions from the 2010-2014 American Community Survey estimates. Associations were examined through multivariate regression models, controlling for community sociodemographics, clustered on county, with robust standard errors. We found that certain pedestrian-oriented zoning provisions (e.g., crosswalks, bike-pedestrian connectivity, street connectivity, bike lanes, bike parking, and more zoning provisions) were associated with reduced income and/or poverty disparities in rates of public transit use and active travel to work. Findings from this study can help to inform cross-sectoral collaborations between the public health, planning, and transportation fields regarding zoning for pedestrian-orientation and active travel.

Exploring the Linkage between Activity-Friendly Zoning, Inactivity, and Cancer Incidence in the United States

Background: Physical activity (PA) protects against cancer and enhances cancer survivorship. Given high inactivity rates nationwide, population-level physical activity facilitators are needed. Several authoritative bodies have recognized that zoning and planning helps create activity-friendly environments. This study examined the association between activity-friendly zoning, inactivity, and cancer in 478 of the most populous U.S. counties. Methods: County geocodes linked county-level data: cancer incidence and smoking (State Cancer Profiles), inactivity (Behavioral Risk Factor Surveillance System), 11 zoning measures (compiled by the study team), and covariates (from the American Community Survey and NAVTEQ). For each zoning measure, single mediation regression models and Sobel tests examined whether activity-friendly zoning was associated with reduced cancer incidence, and whether inactivity mediated those associations. All models were clustered on state with robust SEs and significance at the P < 0.05 level. Results: Zoning for crosswalks, bike–pedestrian connectivity, and bike–pedestrian trails/paths were associated with reduced cancer incidence (β between −0.71 and −1.27, P < 0.05), about 1 case per 100,000 for each 10 percentage-point increase in county population exposure to zoning. Except for crosswalks, each association was mediated by inactivity. However, county smoking attenuated these results, with only crosswalks remaining significant. Results were similar for males (with zoning for bike–pedestrian connectivity, street connectivity, and bike–pedestrian trails/paths), but not females, alone. Conclusions: Zoning can help to create activity-friendly environments that support decreased inactivity, and possibly reduced cancer incidence. Impact: Given low physical activity levels nationwide, cross-sectoral collaborations with urban planning can inform cancer prevention and public health efforts to decrease inactivity and cancer.

Food Purchasing and Preparation at Child Day Care Centers Participating in the Child and Adult Care Food Program in the United States, 2017

BACKGROUND More than 3.6 million children are served daily by the Child and Adult Care Food Program (CACFP)-participating child day care centers. This study provides a nationwide assessment of center-level responsibilities for menu, meal/snack preparation, meal preparer training, and food and beverage (F&B) purchasing. METHODS A nationally representative survey of 5483 CACFP child day care centers was conducted between August 22, 2017, and September 30, 2017. One thousand three hundred forty-three centers (25% response) in 47 states and the District of Columbia responded. Descriptive statistics describe center-level menu, meal, and purchasing practices and center characteristics. Multivariate logistic regressions examined characteristics associated with F&B purchasing sources. RESULTS Menus were primarily prepared by directors/assistant directors and on-site food manager/cooks, while site staff primarily prepared meals/snacks. Fifty-two percent of meal preparers held a food sanitation license, but only 5% had formal nutrition training (e.g., Registered Dietician). Most centers purchased F&B from food service providers (63%), local grocery stores (59%), warehouse stores (40%), or from 2+ sources (50%). Independent centers were more likely to purchase F&B from local grocery stores or 2+, while free or state-subsidized sites were more likely to purchase from a food service provider and less likely to purchase from other sources than were centers charging between
