We determined the criterion validity and test-retest reliability of a brief park use questionnaire. From five US locations, 232 adults completed a brief survey four times and wore a global positioning system (GPS) monitor for three weeks. We assessed validity for park visits during the past week and during a usual week by examining agreement between frequency and duration of park visits reported in the questionnaire to the GPS monitor results. Spearman correlation coefficients (SCC) were used to measure agreement. For past week park visit frequency and duration, the SCC were 0.62-0.65 and 0.62-0.67, respectively. For usual week park visit frequency and duration, the SCC were 0.40-0.50 and 0.50-0.53, respectively. Usual park visit frequency reliability was 0.78-0.88 (percent agreement 69%-82%) and usual park visit duration was 0.75-0.84 (percent agreement 64%-73%). These results suggest that the questionnaire to assess usual and past week park use had acceptable validity and reliability.

We examined the influence of the built environment on pedestrian route selection among adolescent girls. Portable global positioning system units, accelerometers, and travel diaries were used to identify the origin, destination, and walking routes of girls in San Diego, CA and Minneapolis, MN. We completed an inventory of the built environment on every street segment to measure the characteristics of routes taken and not taken. Route-level variables covering four key conceptual built environment domains (Aesthetics, Destinations, Functionality, and Safety) were used in the analysis of route choice. Shorter distance had the strongest positive association with route choice, while the presence of a greenway or trail, higher safety, presence of sidewalks, and availability of destinations along a route were also consistently positively associated with route choice at both sites. The results suggest that it may be possible to encourage pedestrians to walk farther by providing high quality and stimulating routes.

To determine the factors associated with receiving specific treatment (cholinesterase inhibitors or/and memantine) for Alzheimer disease (AD) in elderly patients. An observational study carried out in 289 consecutive outpatients aged >64 years with dementia. We collected data on specific AD therapy, sociodemographic variables, Barthel Index (BI), Lawton and Brody Index (LI), Mini Mental State Examination, Global Deterioration Scale (GDS), Charlson Index and the total number of drugs chronically prescribed. Patients receiving specific therapy for dementia were compared with the rest. Two hundred and thirty-three (80.6%) patients were receiving specific treatment for dementia, with 197 (84.5%) receiving monotherapy and the rest (15.4%) combined therapy. The bivariate analysis showed that age, marital status, place of residence, BI and LI, cognitive status and disease severity (GDS) were factors associated with receiving specific dementia therapy. Multiple stepwise logistic regression analysis showed that a lower BI (beta = -0.25; odds ratio 0.976, 95% confidence interval = 0.966-0.986; p < 0.0001) was the only factor independently associated with not receiving specific therapy for AD. Of the possible factors related to elderly patients receiving specific therapy for AD, a poor BI score was the most important factor associated with not receiving treatment.

In this paper we employ Mecklenburg County, North Carolina, a polycentric city with 10 employment subcenters, as a case study to explore the role of employment subcenters in determining residential location decisions. We estimate discrete choice models of residential location decisions: conditional logit models and heteroscedastic logit models with both the full choice set and sampled choices. We find that access to certain employment subcenters, measured in terms of generalized cost, is an important determinant of households’ residential location decisions. The proximity to specific employment subcenters varies across households with different income levels. These patterns can be explained by existing land use and transportation patterns, as well as by subcenters’ economic specialization.

Satellite precipitation estimates are becoming increasingly available at temporal and spatial scales of interest for hydrological applications. Unfortunately precipitation estimated from global satellites is prone to errors hailing from different sources. The impact of sampling errors on the hydrological cycle of a large-size basin was assessed with a macroscale hydrological model. Synthetic precipitation fields were generated in a Monte Carlo

This study examined the association between the presence of pedestrian and bicycle plans to pedestrian and bicyclist nonfatal and fatal injuries from 1997 to 2009 among 553 North Carolina (NC) municipalities. We considered all municipal plans (n=92; 49 pedestrian; 34 bicycle; and 9 combined plans featuring pedestrian and bicyclist components) published through 2009. Counts of pedestrian and bicyclist nonfatal and fatal injuries came from the NC Department of Transportation crash database, and the estimated number of pedestrian and bicycle trips per municipality in one year were used to calculate pedestrian and bicyclist nonfatal and fatal injury rates. In the 13-year study period, pedestrian/combined municipality plans and bicycle/combined municipality plans were present for 189 (2.6%) and 238 (3.3%) municipality-years, respectively. There were 11,795 nonfatal injuries, 9237 possible nonfatal injuries, and 1075 fatal injuries sustained by pedestrians in pedestrian-motor vehicle crashes. There were 4842 nonfatal injuries, 3666 possible nonfatal injuries, and 134 fatal injuries sustained by bicyclists in bicyclist-motor vehicle crashes. Although not statistically significant, unadjusted nonfatal and fatal injury rates among pedestrians and bicyclists were lower in those municipality-years in which plans had been published that year or in a year prior, compared to municipality-years lacking a plan. Adjusted rate ratios (RR) indicated that pedestrian nonfatal and fatal injury rates decreased in municipality-years with publication of pedestrian/combined plans (nonfatal injury RR: 0.75, 95% confidence interval (CI): 0.68, 0.82; fatal injury RR: 0.63, 95% CI: 0.46, 0.85). However, bicyclist nonfatal and fatal injury rates did not significantly change with publication of bicyclist/combined plans. Our research suggests that plan publication is associated with lower rates of nonfatal and fatal injury in pedestrians; this association was not observed for bicyclists. Further work must determine how the extent of implementation and quality of safety-related content within these plans affects changes in nonfatal and fatal injury rates.

The objective of the present study was to assess the association between type of health insurance coverage and use of diagnostic tests and therapies among patients with AIDS-related Pneumocystis carinii pneumonia (PCP). Fifty-six private, public, and community hospitals in Chicago, Los Angeles, and Miami were selected for the study, and the charts of 890 patients with empirically treated or cytologically confirmed PCP, hospitalized during 1987 to 1990 were retrospectively reviewed. Patients were classified by insurance status: self-pay (n = 56), Medicaid (n = 254), or private insurance, including health maintenance organizations and Medicare (n = 580). Primary outcomes were the use and timing of bronchoscopy, the type and timing of PCP therapy, and in-hospital mortality. The results indicate that Medicaid patients were less likely than privately insured patients to undergo bronchoscopy (relative odds = 0.61; 95% CI = 0.40, 0.93; p = 0.02) or to have their diagnosis of PCP confirmed (relative odds = 0.51; 95% CI = 0.33, 0.77), after adjusting for patient, severity of illness, and hospital characteristics. Medicaid patients were approximately three-fourths more likely than privately insured patients (relative odds = 1.73; 95% CI = 1.01, 2.96; p = 0.04) to die in-hospital, after adjusting for patient, severity of illness, and hospital characteristics. However, with further adjustment for confirmation of PCP, Medicaid patients no longer had a significantly higher likelihood of dying in-hospital. We conclude that Medicaid patients are less likely to receive diagnostic bronchoscopy than privately insured or self-insured patients, more likely to be empirically treated for PCP, and more likely to die in-hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Walk Score® and Transit Score® are open-source measures of the neighborhood built environment to support walking ("walkability") and access to transportation. To investigate associations of Street Smart Walk Score and Transit Score with self-reported transport and leisure walking using data from a large multicity and diverse population-based sample of adults. Data from a sample of 4552 residents of Baltimore MD, Chicago IL, Forsyth County NC, Los Angeles CA, New York NY, and St. Paul MN from the Multi-Ethnic Study of Atherosclerosis (2010-2012) were linked to Walk Score and Transit Score (collected in 2012). Logistic and linear regression models estimated ORs of not walking and mean differences in minutes walked, respectively, associated with continuous and categoric Walk Score and Transit Score. All analyses were conducted in 2012. After adjustment for site, key sociodemographic, and health variables, a higher Walk Score was associated with lower odds of not walking for transport and more minutes/week of transport walking. Compared to those in a…
