People Who Use Illegal Opioids Use of Methadone over Time, and What Characteristics Are Correlated with Staying in Methadone Maintenance Treatment
INTRODUCTION: Methadone maintenance treatment (MMT) is among the best strategies for reducing harms associated with illegal opioid use, yet it is hindered by low rates of treatment initiation and retention that limit its impact. There has been a lack of studies that describe how people who use illegal opioids use methadone-both from opioid treatment programs, and bought illegally-over time, or what factors correlate with long-term participation i…
Built environment influences on park visits for older adults
Investigating the impact of a 20 miles per hour speed limit intervention on road traffic collisions, casualties, speed and volume in Belfast, UK
BACKGROUND: Evidence regarding the effectiveness of 20 miles per hour (mph) speed limit interventions is limited, and rarely have long-term outcomes been assessed. We investigate the effect of a 20 mph speed limit intervention on road traffic collisions, casualties, speed and volume at 1 and 3 years post-implementation. METHODS: An observational, repeated cross-sectional design was implemented, using routinely collected data for road traffic coll…
Age-friendly cities, knowledge and urban restructuring
Age-friendly cities and communities have emerged as a significant policy, participative and governance response to ageing and its spatial effects. This paper argues that it has important benefits in mobilizing older people, placing age on the urban agenda and building recognition across politicians, policy makers and programme managers. Based on the experience of Belfast (UK), the analysis suggests, however, that it needs to be understood within …

Romantic conflict narratives and associations with psychological relationship aggression in emerging adult couples
This cross-sectional study aimed to understand how emerging adult couples interpreted relationship conflicts, and whether such meaning making was associated with psychological relationship aggression and moderated by gender. We specified the I Cubed model of relationship aggression to examine how in the context of recounting relationship conflicts, the impellance factors of anger and break-up anxiety might increase and the inhibition factor of pe…
An intensive model of care for hepatitis C virus screening and treatment with direct‐acting antivirals in people who inject drugs in Nairobi, Kenya
BACKGROUND AND AIMS: Hepatitis C virus (HCV) treatment is essential for eliminating HCV in people who inject drugs (PWID), but has limited coverage in resource-limited settings. We measured the cost-effectiveness of a pilot HCV screening and treatment intervention using directly observed therapy among PWID attending harm reduction services in Nairobi, Kenya. DESIGN: We utilized an existing model of HIV and HCV transmission among current and forme…
A qualitative exploration of the mechanisms, pathways and public health outcomes of a city centre 20mph speed limit intervention
Environmental, health, wellbeing, social and equity effects of urban green space interventions
BACKGROUND: As populations become increasingly urbanised, the preservation of urban green space (UGS) becomes paramount. UGS is not just dedicated recreational space such as public parks, but other types of informal green space are important, for example, street trees and roof gardens. Despite the potential from cross-sectional evidence, we know little about how to design new, or improve or promote existing UGS for health, wellbeing, social and e…
Built environment correlates of physical activity and sedentary behaviour in older adults
Study protocol
The HULAP study has been designed and implemented by a multi-disciplinary team and integrates differing methodologies to purposefully impact on policy and practice on healthy ageing in high and low-middle income countries. It has particular strengths in its combination of objective and self-reported measures using validated tools and the integration of GPS, accelerometer and GIS data to provide a robust assessment of 'spatial energetics'. The str…

Contextual Predictors of Injection Drug Use Among Black Adolescents and Adults in US Metropolitan Areas, 1993–2007
Objectives. We sought to determine whether contextual factors shape injection drug use among Black adolescents and adults. Methods. For this longitudinal study of 95 US metropolitan statistical areas (MSAs), we drew annual MSA-specific estimates of the prevalence of injection drug use (IDU) among Black adolescents and adults in 1993 through 2007 from 3 surveillance databases. We used existing administrative data to measure MSA-level socioeconomic…
Spatial scale, time and process in mega-events
A focus on the 'mega' aspect of hallmark events can divert attention from the micro - those local communities who are most impacted by the event. Similarly, attention to the 'event' aspect underplays the long process of bidding and preparation before any putative legacy of urban transformation for local people. This paper uses qualitative data to unpack the complex and multi-layered views of local residents, living in a deprived neighbourhood bes…
Validity of the Global Physical Activity Questionnaire (GPAQ) in assessing levels and change in moderate-vigorous physical activity and sedentary behaviour
Levels of agreement with objective measurements indicate the GPAQ is a valid measure of MVPA and change in MVPA but is a less valid measure of current levels and change in SB. Thus, GPAQ appears to be an appropriate measure for assessing the effectiveness of interventions to promote MVPA
P38 The impact of urban renewal on engagement in physical activity in a socio-economically disadvantaged population
Background Most adults in Europe lead sedentary lives; their physical inactivity is associated with a rising prevalence of obesity and is considered to contribute significantly to health inequalities. A recent NICE (2006) review concluded that, “there is an urgent need to conduct research into the effectiveness of environmental interventions, particularly within socially excluded sectors of the population who have the highest prevalence of physic…
The Combined Effects of Treatment Intensity, Self-Help Groups and Patient Attributes on Drinking Outcomes
Better understanding of the diverse factors that predict alcoholism treatment outcomes is essential to improving treatment strategies. Patients accepted for treatment at a multimodality program were interviewed and followed-up at three months and one year after admission. The study tested a set of hypotheses relating to the effects on drinking outcomes of treatment modality, modality matching, treatment retention, aftercare, self-help group parti…
Taxometric Analysis of Fuzzy Categories
A small Monte Carlo study examined the performance of a form of taxometric analysis (the MAXCOV procedure) with fuzzy data sets. These combine taxonic (categorical) and nontaxonic (continuous) features, containing a subset of casts with intermediate degrees of category membership. Fuzzy data sets tended to yield taxonic findings on plot inspection and two popular consistency tests, even when the degree of fuzziness, i.e., the proportion of interm…
Knowledge about HIV/Aids, the perceived risks of infection and sources of information of Asian-Indian adolescents born in the USA
This study examined the extent and specificity of knowledge about HIV/AIDS, the most used sources of information and the usefulness of these sources among Asian-Indian adolescents who were born in the USA and whose parents emigrated from India. Although 86% knew that having unsafe sex with a person infected with HIV could transmit HIV, 47% did not know that sharing a razor with an HIV-positive person could do so, and a significant proportion beli…

Peer Networks, Parental Attributes, and Drug Use Among Asian-Indian Adolescents Born in the United States
Robustness of Taxometric Analysis with Skewed Indicators
A small Monte Carlo study was conducted to determine whether MAXCOV analysis, a taxometric method for testing between discrete (“taxonic”) and continuous models of latent variables, is robust when indicators of the latent variable are skewed. Analysis of constructed data sets containing three levels of skew indicated that the MAXCOV procedure is unlikely to yield spurious findings of taxonicity even when skewness is considerable. However, care mu…

Rites of Conquest
For many thousands of years before the arrival of Europeans, Michigan's native peoples, the Anishnabeg, thrived in the forests and along the shores of the Great Lakes. Theirs were cultures in delicate social balance and in economic harmony with the natural order. Rites of Conquest details the struggles of Michigan Indians - the Ojibwa, Ottawa, and Potawatomi, and their neighbors - to maintain unique traditions in the wake of contact with Euro-Ame…
