Lin Q, Aguilera JAR, Williams LD, Mackesy-Amiti ME, Latkin C, Pineros J, Kolak M, Boodram B. Social-spatial network structures among young urban and suburban persons who inject drugs in a large metropolitan area. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 122:104217. [PMID: 37862848 DOI: 10.1016/j.drugpo.2023.104217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 09/24/2023] [Accepted: 09/25/2023] [Indexed: 10/22/2023]
Abstract
BACKGROUND Recent studies underscore the significance of adopting a syndemics approach to study opioid misuse, overdose, hepatitis C (HCV) and HIV infections, within the broader context of social and environmental contexts in already marginalized communities. Social interactions and spatial contexts are crucial structural factors that remain relatively underexplored. This study examines the intersections of social interactions and spatial contexts around injection drug use. More specifically, we investigate the experiences of different residential groups among young (aged 18-30) people who inject drugs (PWID) regarding their social interactions, travel behaviors, and locations connected to their risk behaviors. By doing so, we aim to achieve a more comprehensive understanding of the multidimensional risk environment, thereby facilitating the development of informed policies. METHODS We collected and examined data regarding young PWID's egocentric injection network and geographic activity spaces (i.e., where they reside, inject drugs, purchase drugs, and meet sex partners). Participants were stratified based on the location of all place(s) of residence in the past year i.e., urban, suburban, and transient (both urban and suburban) to i) elucidate geospatial concentration of risk activities within multidimensional risk environments based on kernel density estimates; and ii) examine spatialized social networks for each residential group. RESULTS Participants were mostly non-Hispanic white (59%); 42% were urban residents, 28% suburban, and 30% transient. We identified a spatial area with concentrated risky activities for each residential group on the West side of Chicago in Illinois where a large outdoor drug market area is located. The urban group (80%) reported a smaller concentrated area (14 census tracts) compared to the transient (93%) and suburban (91%) with 30 and 51 tracts, respectively. Compared to other areas in Chicago, the identified area had significantly higher neighborhood disadvantages. Significant differences were observed in social network structures and travel behaviors: suburban participants had the most homogenous network in terms of age and residence, transient participants had the largest network (degree) and more non-redundant connections, while the urban group had the shortest travel distance for all types of risk activities. CONCLUSION Distinct residential groups exhibit varying patterns of network interaction, travel behaviors, and geographical contexts related to their risk behaviors. Nonetheless, these groups share common concentrated risk activity spaces in a large outdoor urban drug market area, underscoring the significance of accounting for risk spaces and social networks in addressing syndemics within PWID populations.

Abstract
OBJECTIVE Chinese immigrant older adults who live in affordable housing are at high risk of experiencing social isolation during the COVID-19 pandemic, which can affect their mental health. Using a triangulation mixed-methods approach, this study describes Chinese immigrant older adults' social network, mental health status, and their associations during the pandemic. METHODS Semi-structured in-depth interviews were conducted with 26 Chinese immigrant older adults from June to August 2021. The structure and characteristics of participants' social networks were assessed with a name-generating approach. Mental health status was self-reported with Geriatric Depression Scale and UCLA loneliness scale. RESULTS This sample (mean age = 78.12, 69.23% female), on average, had 5.08 social ties in their network, and 58% were family ties. Participants reported decreased social contact, family and friends interaction patterns specific to immigrants, and constantly being in a low mood and bored. Having closer relationships with others and maintaining the same or higher contact frequency after COVID-19 onset was associated with fewer depressive symptoms. Resilience from religious beliefs, neighbors as role models, and wisdom learned from past experiences were reported. CONCLUSION Knowledge built in this study can inform respondence to future crises like the COVID-19 pandemic in affordable housing settings serving older immigrant populations.

Abstract
Background It is estimated that there are 1.5% US adult population who inject drugs in 2018, with young adults aged 18-39 showing the highest prevalence. PWID are at a high risk of many blood-borne infections. Recent studies have highlight the importance of employing the syndemic approach to study opioid misuse, overdose, HCV and HIV, along with the social and environmental contexts where these interrelated epidemics occur in already marginalized communities. Social interactions and spatial contexts are important structural factors that are understudied. Methods Egocentric injection network and geographic activity spaces for young (aged 18-30) PWID and their injection, sexual, and social support network members (i.e., where reside, inject drugs, purchase drugs, and meet sex partners) were examined using baseline data from an ongoing longitudinal study (n=258). Participants were stratified based on the location of all place(s) of residence in the past year i.e., urban, suburban, and transient (both urban and suburban) to i) elucidate geospatial concentration of risk activities within multi-dimensional risk environments based on kernel density estimates; and ii) examine spatialized social networks for each residential group. Results Participants were mostly non-Hispanic white (59%); 42% were urban residents, 28% suburban, and 30% transient. We identified a spatial area with concentrated risky activities for each residence group on the West side of Chicago where a large outdoor drug market area is located. The urban group (80%) reported a smaller concentrated area (14 census tracts) compared to the transient (93%) and suburban (91%) with 30 and 51 tracts, respectively. Compared to other areas in Chicago, the identified area had significantly higher neighborhood disadvantages (e.g., higher poverty rate, p <0.001). Significant ( p <0.01 for all) differences were observed in social network structures: suburban had the most homogenous network in terms of age and residence, transient participants had the largest network (degree) and more non-redundant connections. Conclusion We identified concentrated risk activity spaces among PWID from urban, suburban, and transient groups in a large outdoor urban drug market area, which highlights the need for considering the role of risk spaces and social networks in addressing the syndemics in PWID populations.

Abstract
BACKGROUND Recent studies have found that women with obstetric disorders are at increased risk for a variety of long-term complications. However, the underlying pathophysiology of these connections remains undetermined. A network-based view incorporating knowledge of other diseases and genetic associations will aid our understanding of the role of genetics in pregnancy-related disease complications. METHODS We built a disease-disease network (DDN) using UK Biobank (UKBB) summary data from a phenome-wide association study (PheWAS) to elaborate multiple disease associations. We also constructed egocentric DDNs, where each network focuses on a pregnancy-related disorder and its neighboring diseases. We then applied graph-based semi-supervised learning (GSSL) to translate the connections in the egocentric DDNs to pathologic knowledge. RESULTS A total of 26 egocentric DDNs were constructed for each pregnancy-related phenotype in the UKBB. Applying GSSL to each DDN, we obtained complication risk scores for additional phenotypes given the pregnancy-related disease of interest. Predictions were validated using co-occurrences derived from UKBB electronic health records. Our proposed method achieved an increase in average area under the receiver operating characteristic curve (AUC) by a factor of 1.35 from 55.0% to 74.4% compared to the use of the full DDN. CONCLUSION Egocentric DDNs hold promise as a clinical tool for the network-based identification of potential disease complications for a variety of phenotypes.

Psychosocial factors affecting sleep misperception in middle-aged community-dwelling adults. PLoS One 2020; 15:e0241237.

Abstract
Sleep misperception has long been a major issue in the field of insomnia research. Most studies of sleep misperception examine sleep underestimation by comparing the results of polysomnography conducted in a laboratory environment with patients' sleep diary entries. We aimed to investigate psychosocial characteristics of adults who underestimated or overestimated sleep time in a nonclinical, middle-aged community-dwelling population. We collected one week of sleep data with wrist-worn accelerometers. We used egocentric social network analysis to analyze the effects of psychosocial factors. Among 4,060 study participants, 922 completed the accelerometer substudy. Underestimation was defined as an accelerometer-measured sleep time ≥ 6 h and a subjective sleep time < 6 h. Overestimation was defined as an objective sleep time < 6 h and a subjective sleep time ≥ 6 h. Psychosocial characteristics of the sleep misperception group were evaluated using multivariate regression analysis. A total of 47 participants underestimated sleep time, and 420 overestimated sleep time. Regression analysis revealed that women, living with spouse, economic satisfaction, and bridging potential had protective effects against sleep underestimation. Blame from a spouse involved a 3.8-times higher risk of underestimation than the control group (p = 0.002). In men, discussing concerns with a spouse had a protective effect against underestimation (p < 0.001). Economic satisfaction, feeling social network-based intimacy, and support from a spouse were associated with overestimation in women. In men, feeling social network-based intimacy was also associated with overestimation (p < 0.001). We found that social relationship quality was related to sleep overestimation and underestimation. This association was marked in women. Good social relationships may have positive effects on sleep misperception via attenuation of negative emotional reactions and effects on emotional regulation.

Abstract
Objective: We are yet to understand how widely parents seek asthma medication management information for their children, how they are used for health information, how parents engage with them and their influence on parent's decision-making. This study aimed to gauge the current level of asthma knowledge and skills of parents of children with asthma and gain insight into who and what influences their child's asthma medication management decisions. Method: Social network theory was used to map parents' asthma networks and identify the level of influence of each individual/resource nominated. Parents of children with asthma (aged 4-18 years) were interviewed, completed an asthma network map, questionnaires and an inhaler technique assessment. Results: Twenty-six parents participated and had significant gaps in asthma knowledge and inhaler technique skills. The asthma networks of participants ranged from two to ten individuals/resources, with an average number of five. The most commonly nominated individual/resource was general practitioners followed by family members and the internet. Professional connections represented 44% of individuals/resources in networks, personal connections 42% and impersonal connections 14%. When parents were asked about how influential individuals/resources were, professional connections represented 53% of parents influences, personal connections 36% and impersonal connections 11%. Conclusion: This study highlights the priority and co-influence of non-medical sources of information/support on parent's behaviors and decision-making with regards to their child's asthma medicine taking. In further understanding the complexities surrounding these connections and relationships, HCPs are better positioned to assist parents in addressing their needs and better supporting them in the management of their child's asthma.
