A systematic review and meta-analysis of trials of social network interventions in type 2 diabetes

Factors influencing self-management behaviors in persons with lupus nephritis: A cross-sectional study

Background

Patients with lupus nephritis experience disease symptoms and side effects from treatment. Although self-management behaviors are important in patients with this disease, there is limited research on the factors influencing these behaviors.

Objective

This study aimed to examine the factors influencing self-management behaviors in patients with lupus nephritis.

Methods

This cross-sectional study was conducted in 240 patients with lupus nephritis at a university hospital in Thailand between August 2019 and December 2020 using a random sampling method. Data were collected using a demographic and clinical characteristic questionnaire, Self-Management Behavior Questionnaire, Self-efficacy for Managing Chronic Disease: A 6-item Scale, Knowledge about Lupus Nephritis Questionnaire, Family Support Scale, Social Networks in Adult Life Questionnaire, and Memorial Symptom Assessment Scale for Lupus Nephritis. Descriptive statistics and multiple linear regression analyses were employed.

Results

The participants reported a moderate level of self-management behaviors. Multiple regression analyses revealed that disease duration, income, symptoms, self-efficacy, knowledge, family support, social networks, and classes of lupus nephritis significantly explained 21% of the variance in self-management behaviors (R2 = 0.21; F(8,231) = 7.73; p <0.001). Family support (β = 0.32, p <0.001) and symptoms (β = -0.23, p <0.001) were significant determinants of self-management behaviors in patients with lupus nephritis.

Conclusion

The findings provide valuable insight for nurses to better understand the factors influencing self-management behaviors in patients with lupus nephritis. Patients with low family support and high symptom severity may face difficulty in performing self-management behaviors. Nurses should pay more attention to these patients and provide family-based interventions to optimize self-management behaviors in this population.

Prediabetes Progression and Reversion: Social Factors and Racial/Ethnic Differences

OBJECTIVE

Racial and ethnic minorities are disproportionately affected by diabetes. Social characteristics, such as family structure, social support, and loneliness, may contribute to these health disparities. In a nationally representative sample of diverse older adults, we evaluated longitudinal rates of both progression from prediabetes to diabetes and reversion from prediabetes to normoglycemia.

RESEARCH DESIGN AND METHODS

Using the longitudinal Health and Retirement Study (2006-2014), our sample included 2625 follow-up intervals with a prediabetes baseline (provided by 2229 individuals). We analyzed 4-year progression and reversion rates using HbA1c and reported presence or absence of physician-diagnosed diabetes. We utilized chi-square and logistic regression models to determine how race/ethnicity and social variables influenced progression or reversion controlling for comorbidities and demographics.

RESULTS

Overall, progression to diabetes was less common than reversion (17% vs. 36%). Compared to Whites, Hispanic/Latino respondents had higher odds of progression to diabetes from prediabetes while Black respondents had lower odds of reversion, adjusting for physical health and demographics. For social variables, Hispanics/Latinos had the highest reliance on and openness with family and the lowest rates of loneliness. The inclusion of social variables in regression models reduced the odds of progression for Hispanics/Latinos but did not alter Black's lower rate of reversion.

CONCLUSIONS

Hispanic/Latinos and Blacks not only had different transition pathways leading to diabetes, but also had different social profiles, affecting Hispanic/Latino progression, but not Black reversion. These differences in the influence of social variables on diabetes risk may inform the design of culturally-specific efforts to reduce disparities in diabetes burden.

Social support via Internet communication technology for diabetes self-management: a scoping review

Background

The global prevalence of diabetes has been increasing over the past 30 years, leading to a rise in complications; diabetes is the leading cause of amputations, blindness, and kidney failure in developed countries. Diabetes self-management is challenging due to the complex lifestyle changes required. Social support from family and friends plays a crucial role in overcoming barriers to healthy behavior choices. Integrating Internet and communication technologies with social support interventions has the potential to improve diabetes self-management.

Methods

A scoping review was conducted by searching PubMed, Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Association for Computing Machinery (ACM) Digital Library databases for studies combining diabetes, Internet and communication technologies, and social support interventions. Inclusion criteria focused on adult patients with diabetes and primarily Internet and communication technologies-based strategies to initiate and enhance social support. Data abstraction included study population, design, outcomes, social support domains emphasized, support relationship intervention strategy, and Internet and communication technologies modality.

Results

The review identified 39 articles and 33 unique studies representing 27 unique interventions utilizing peer web forums, interactive voice recordings, messaging-based interventions (including Short Message Service and instant messaging), and email as Internet and communication technologies modalities. Various outcomes were reported, including improvements in perception of social support, psychosocial well-being, behavior changes, and clinical outcomes. Existing support relationships may be more effective in promoting behavior change and clinical outcomes compared to developing new relationships. Studies that explicitly measured patients' perception of support consistently showed improvements in psycho-social, behavioral, and clinical outcomes.

Conclusions

This scoping review highlights the pivotal role of social support in diabetes self-management. By integrating Internet and communication technologies into interventions, diverse modalities such as web forums and text messaging have shown promise in enhancing patients' perception of support and improving psychosocial well-being, behavior changes, and clinical outcomes. The emphasis on leveraging existing support relationships, rather than establishing new ones, underscores the effectiveness of personalized, patient-centered approaches. These findings provide essential insights for healthcare strategies, emphasizing the need to harness technology and existing social networks to empower individuals in managing diabetes effectively.

Associations between dimensions of the social environment and cardiometabolic risk factors: Systematic review and meta-analysis

Aim

The social environment (SE), including social contacts, norms and support, is an understudied element of the living environment which impacts health. We aim to comprehensively summarize the evidence on the association between the SE and risk factors of cardiometabolic disease (CMD).

Methods

We performed a systematic review and meta-analysis based on studies published in PubMed, Scopus and Web of Science Core Collection from inception to 16 February 2021. Studies that used a risk factor of CMD, e.g., HbA1c or blood pressure, as outcome and social environmental factors such as area-level deprivation or social network size as independent variables were included. Titles and abstracts were screened in duplicate. Study quality was assessed using the Newcastle-Ottawa Scale. Data appraisal and extraction were based on the study protocol published in PROSPERO. Data were synthesized through vote counting and meta-analyses.

Results

From the 7521 records screened, 168 studies reported 1050 associations were included in this review. Four meta-analyses based on 24 associations suggested that an unfavorable social environment was associated with increased risk of cardiometabolic risk factors, with three of them being statistically significant. For example, individuals that experienced more economic and social disadvantage had a higher "CVD risk scores" (OR = 1.54, 95%CI: 1.35 to 1.84). Of the 458 associations included in the vote counting, 323 (71%) pointed towards unfavorable social environments being associated with higher CMD risk.

Conclusion

Higher economic and social disadvantage seem to contribute to unfavorable CMD risk factor profiles, while evidence for other dimensions of the social environment is limited.

"No sufro, estoy bien/I am not suffering, so I am doing OK": A mixed method exploration of individual and network-level factors and Type 2 Diabetes Mellitus (T2DM) among Mexican American adults in New York City

INTRODUCTION

The prevalence of type 2 Diabetes Mellitus (T2DM) is 2-3 times greater among Mexican Americans than non-Latino whites, and Mexican Americans are more likely to develop T2DM at younger ages and experience higher rates of complications. Social networks might play a crucial role in both T2DM etiology and management through social support, access to resources, social engagement, and health behavioral norms.

OBJECTIVE

To quantitatively identify the social network features associated with glycated hemoglobin (HbA1c) in a community sample of Mexican immigrants residing in New York City, and to explore the extent to which these quantitative findings converge with qualitative narratives of their lived experiences.

METHODS

This study used a convergent mixed methods design. To collect personal network data, we used EgoWeb, and obtained 1,400 personal network ties from 81 participants. HbA1c readings were collected using dried blood spots and categorized according to the laboratory criteria of the American Diabetes Association. Additional survey data were collected using Qualtrics software. To investigate the significance of the network-level factors after accounting for the socioeconomic and demographic individual-level factors that the literature indicates to be associated with T2DM, we used a multiple regression model on quantitative data sources. For the qualitative portion of the study, we selected a subset of individuals who participated in the quantitative portion, which represented 500 personal network ties from 25 participants. We conducted in-depth interviews guided by the visualization of these ties to explore who was helpful or difficult in managing their health and health behaviors.

RESULTS

Individual-level indicators associated with lower HbA1c scores were body mass index (β = -0.07, p<0.05), and healthy eating index scores (β = -0.03, p<0.02). The network-level predictor associated with higher HbA1c levels was the percentage of diabetic alters in the network (β = 0.08, p <0.001, with a 25% increase in the percentages associated 2.0 change in HbA1c levels. The qualitative data highlighted that most of the diabetes-related information diffused through the social networks of our participants was related to dietary practices, such as reducing sugar and red meat consumption, eating out less, and reducing portion sizes. Notably, even among those with elevated levels and diabetes-related health complications, HbA1c was not considered a part of the lay descriptions of good health since they were not "suffering." Participants regarded doctors as the ultimate authority in diabetes care, even if they had supportive members in their personal networks.

CONCLUSION

Our study provides quantitative evidence for the significant role of diabetic network members in the etiology and management of T2DM among Mexican Americans. Our qualitative findings suggest important ley terms for T2DM management and the importance of physicians, which could be included in in future social networks studies seeking to diffuse diabetes-related health information for T2DM prevention and management efforts in this population.

Social isolation, loneliness and subsequent risk of major adverse cardiovascular events among individuals with type 2 diabetes mellitus

Background

Individuals with type 2 diabetes mellitus (T2DM) are more vulnerable to social disconnection compared with the general population; however, there are few relevant studies investigating this issue.

Aims

To investigate whether social isolation or loneliness may be associated with subsequent risk of developing major adverse cardiovascular events, whether these associations vary according to fatal and non-fatal outcomes and how behavioural, psychological and physiological factors mediate these associations.

Methods

This longitudinal analysis included data from 19 360 individuals with T2DM at baseline (2006-2010) from the UK Biobank. Social isolation and loneliness were measured using self-report questionnaires. The study outcomes included the first events of myocardial infarction (MI) or stroke (n=2273) and all-cause (n=2820) or cardiovascular disease-related mortality through linked hospital data or death registries.

Results

Over a median follow-up of 12.4 years (interquartile range (IQR): 11.6-13.3 years), participants who were more socially isolated (most social isolation vs least social isolation) experienced increased risks for all-cause (hazard ratio (HR) : 1.33, 95% confidence interval (CI): 1.19 to 1.47) and cardiovascular disease (HR: 1.36, 95% CI: 1.17 to 1.59) mortality but not first MI or stroke. Loneliness (yes vs no) was associated with a greater risk for a composite of incident MI or stroke (HR: 1.37, 95% CI: 1.19 to 1.57) but not mortality. Social isolation was associated with fatal MI and stroke, whereas loneliness was associated with non-fatal MI and stroke. The significant associations of social isolation and loneliness with outcomes were mainly mediated by behavioural factors (mediating proportion: 17.8%-28.2% and 17.6%-17.8%, respectively).

Conclusions

Among individuals with T2DM, social isolation and loneliness are associated with a greater risk of developing major adverse cardiovascular events, with differences in both risks stratified according to fatal and non-fatal events and underlying mediating factors.

Care networks of home-dwelling older adults in the Netherlands: proof of concept of a network typology

BACKGROUND

Studies on care networks of home-dwelling older adults often focus on network composition. However, looking at network mechanisms (negotiation, navigation and contagion) can be helpful to improve the support generated by the care network. A European study on diabetes patients identified network types based on interaction, which can be beneficial (generative, proxy) or detrimental (struggling, avoidant) to support. This study explored whether these network types are present in care networks of home-dwelling older adults in the Netherlands, and how these types manifest in composition or mechanisms.

METHODS

The present study is a cross-sectional qualitative study of care networks supporting 19 home-dwelling older adults. Face-to-face interviews were conducted with the older adult and their informal and formal caregivers between March and September 2016. Network composition and mechanisms were abstracted from content analysis of interview transcripts, then network type was determined for each network.

RESULTS

Three of the 19 networks had only one respondent and were excluded, yielding 16 for analysis: eight proxy networks, three generative networks, two avoidant networks, one struggling network, and two possibly hybrid networks. In the proxy networks, all negotiation and navigation were centralised by the proxy. In generative networks, negotiation was possible if the older adult could reciprocate, and the network supported this. In avoidant networks, informal and formal caregivers had to deal with an older adult who refused support. In the struggling network, the underlying problem could not be addressed. Furthermore, two networks could either be hybrid network types or networks in a transition process from generative to proxy network.

CONCLUSION

Our results suggest that the network typology developed in the context of diabetes patients is relevant and mostly replicable in networks of multi-morbid older adults. We found that a care network typology based on mechanisms offered additional information beyond network composition. It also appears that the network type can change over time, but more research is needed to confirm this. This study suggests that interventions in avoidant or struggling networks are difficult. Also, actions of network participants seemed aimed at developing proxy networks. Interventions designed to develop or maintain generative networks seem underused.

Peer Support to Enhance Type 2 Diabetes Prevention Among African American and Latino Adults

Social support occurs within complex social networks that are diffusely embedded within the social determinants of health. Social networks operate through five primary interconnected pathways: (1) provision of social support; (2) social influence; (3) social engagement; (4) social capital; and (5) social cohesion. Research has demonstrated that increased social support can have a beneficial impact on Type 2 Diabetes (T2DM) prevention and outcomes through culturally tailored Diabetes Prevention Programs in minority communities. Further research is needed to fully measure the impact of social network peer support on T2DM outcomes to better operationalize and scale up community specific interventions.

Preventing type 2 diabetes: A research agenda for behavioural science

AIMS

The aim of this narrative review was to identify important knowledge gaps in behavioural science relating to type 2 diabetes prevention, to inform future research in the field.

METHODS

Seven researchers who have published behaviour science research applied to type 2 diabetes prevention independently identified several important gaps in knowledge. They met to discuss these and to generate recommendations to advance research in behavioural science of type 2 diabetes prevention.

RESULTS

A total of 21 overlapping recommendations for a research agenda were identified. These covered issues within the following broad categories: (a) evidencing the impact of whole population approaches to type 2 diabetes prevention, (b) understanding the utility of disease-specific approaches to type 2 diabetes prevention such as Diabetes Prevention Programmes (DPPs) compared to generic weight loss programmes, (c) identifying how best to increase reach and engagement of DPPs, whilst avoiding exacerbating inequalities, (d) the need to understand mechanism of DPPs, (e) the need to understand how to increase maintenance of changes as part of or following DPPs, (f) the need to assess the feasibility and effectiveness of alternative approaches to the typical self-regulation approaches that are most commonly used, and (g) the need to address emotional aspects of DPPs, to promote effectiveness and avoid harms.

CONCLUSIONS

There is a clear role for behavioural science in informing interventions to prevent people from developing type 2 diabetes, based on strong evidence of reach, effectiveness and cost-effectiveness. This review identifies key priorities for research needed to improve existing interventions.

Social network interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease

BACKGROUND

Globally, cardiovascular diseases (CVD, that is, coronary heart (CHD) and circulatory diseases combined) contribute to 31% of all deaths, more than any other cause. In line with guidance in the UK and globally, cardiac rehabilitation programmes are widely offered to people with heart disease, and include psychosocial, educational, health behaviour change, and risk management components. Social support and social network interventions have potential to improve outcomes of these programmes, but whether and how these interventions work is poorly understood.  OBJECTIVES: To assess the effectiveness of social network and social support interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease. The comparator was usual care with no element of social support (i.e. secondary prevention alone or with cardiac rehabilitation).  SEARCH METHODS: We undertook a systematic search of the following databases on 9 August 2022: CENTRAL, MEDLINE, Embase, and the Web of Science. We also searched ClinicalTrials.gov and the WHO ICTRP. We reviewed the reference lists of relevant systematic reviews and included primary studies, and we contacted experts to identify additional studies.  SELECTION CRITERIA: We included randomised controlled trials (RCTs) of social network or social support interventions for people with heart disease. We included studies regardless of their duration of follow-up, and included those reported as full text, published as abstract only, and unpublished data.

DATA COLLECTION AND ANALYSIS

Using Covidence, two review authors independently screened all identified titles. We retrieved full-text study reports and publications marked 'included', and two review authors independently screened these, and conducted data extraction. Two authors independently assessed risk of bias, and assessed the certainty of the evidence using GRADE. Primary outcomes were all-cause mortality, cardiovascular-related mortality, all-cause hospital admission, cardiovascular-related hospital admission, and health-related quality of life (HRQoL) measured at > 12 months follow-up.  MAIN RESULTS: We included 54 RCTs (126 publications) reporting data for a total of 11,445 people with heart disease. The median follow-up was seven months and median sample size was 96 participants. Of included study participants, 6414 (56%) were male, and the mean age ranged from 48.6 to 76.3 years. Studies included heart failure (41%), mixed cardiac disease (31%), post-myocardial infarction (13%), post-revascularisation (7%), CHD (7%), and cardiac X syndrome (1%) patients. The median intervention duration was 12 weeks. We identified notable diversity in social network and social support interventions, across what was delivered, how, and by whom.  We assessed risk of bias (RoB) in primary outcomes at > 12 months follow-up as either 'low' (2/15 studies), 'some concerns' (11/15), or 'high' (2/15). 'Some concerns' or 'high' RoB resulted from insufficient detail on blinding of outcome assessors, data missingness, and absence of pre-agreed statistical analysis plans. In particular, HRQoL outcomes were at high RoB. Using the GRADE method, we assessed the certainty of evidence as low or very low across outcomes. Social network or social support interventions had no clear effect on all-cause mortality (risk ratio (RR) 0.75, 95% confidence interval (CI) 0.49 to 1.13, I2 = 40%) or cardiovascular-related mortality (RR 0.85, 95% CI 0.66 to 1.10, I2 = 0%) at > 12 months follow-up. The evidence suggests that social network or social support interventions for heart disease may result in little to no difference in all-cause hospital admission (RR 1.03, 95% CI 0.86 to 1.22, I2 = 0%), or cardiovascular-related hospital admission (RR 0.92, 95% CI 0.77 to 1.10, I2 = 16%), with a low level of certainty. The evidence was very uncertain regarding the impact of social network interventions on HRQoL at > 12 months follow-up (SF-36 physical component score: mean difference (MD) 31.53, 95% CI -28.65 to 91.71, I2 = 100%, 2 trials/comparisons, 166 participants; mental component score MD 30.62, 95% CI -33.88 to 95.13, I2 = 100%, 2 trials/comparisons, 166 participants).  Regarding secondary outcomes, there may be a decrease in both systolic and diastolic blood pressure with social network or social support interventions. There was no evidence of impact found on psychological well-being, smoking, cholesterol, myocardial infarction, revascularisation, return to work/education, social isolation or connectedness, patient satisfaction, or adverse events.  Results of meta-regression did not suggest that the intervention effect was related to risk of bias, intervention type, duration, setting, and delivery mode, population type, study location, participant age, or percentage of male participants.  AUTHORS' CONCLUSIONS: We found no strong evidence for the effectiveness of such interventions, although modest effects were identified in relation to blood pressure. While the data presented in this review are indicative of potential for positive effects, the review also highlights the lack of sufficient evidence to conclusively support such interventions for people with heart disease. Further high-quality, well-reported RCTs are required to fully explore the potential of social support interventions in this context. Future reporting of social network and social support interventions for people with heart disease needs to be significantly clearer, and more effectively theorised, in order to ascertain causal pathways and effect on outcomes.

Global comparison of the effect of non-pharmacological interventions on glycemic control in patients with type 2 diabetes: A network meta-analysis from 107 randomized controlled trials

OBJECTIVE

To investigate the effectiveness of non-pharmacological interventions (NPIs) on glycemic control in patients with type 2 diabetes (T2D) and to provide guidance for clinical healthcare-giver.

DESIGN

Network meta-analysis (NMA).

SETTING AND PARTICIPANTS

Randomized controlled trials comparing the effect of NPIs with usual care, waitlist, or other NPIs on glycemic control in patients with T2D.

METHODS

This NMA was guided by frequentist framework. PubMed, Embase, the Cochrane Library Central Register of Controlled Trials, Cumulated Index to Nursing and Allied Health Literature, and Web of Science were searched from their inception until January 2023. The primary outcome was HbA1c and secondary outcomes were cardiovascular risk scores and related psychosocial scores. Mean differences and standardized mean differences were pooled using NMA. Study quality was assessed with the Confidence in Network Meta-analysis.

RESULTS

A total of 107 studies (10,496 participants) were included. The median sample size of the included studies was 64 (range, 10-563) and the median duration was 3 months (range, 1-24). Compared to usual care, all NPIs except acupuncture (MD: -0.28; 95 % CI: -1.02, 0.26) and psychological therapy (MD: -0.29; 95 % CI: -0.66, 0.08) showed significantly differences in improving glycemic control in patients with T2D. And according to the results of surface under the cumulative ranking analysis and Cluster ranking, meditation therapy was considered to the best choice when balancing the efficacy of glycemic control with self-efficacy and diabetes related problems, while nutrition therapy was considered to the best choice when balancing quality of life with risk of cardiovascular complications.

CONCLUSIONS

These findings validate the efficacy of NPIs for glycemic control in patients with T2D and suggest that healthcare-giver should consider both the efficacy of interventions and the psychosocial needs of patients when developing NPIs programs.

Gender invariance in the relationship between social support and glycemic control

BACKGROUND

Social support (SS) is important in diabetes self-management; however, little is known about how different types of SS influence diabetes outcomes in men and women with type 2 diabetes mellitus (T2DM). Therefore, the aims of this study were to investigate the relationships between types of SS and glycemic control and self-care behaviors and assess whether the relationships differ by gender.

METHODS

Cross-sectional study of 615 adults from two primary care clinics in the southeastern U.S. Outcomes were hemoglobin A1c (HbA1c) extracted from the medical records, and self-management behaviors (general diet, specific diet, exercise, blood glucose testing, foot care) measured using the Summary of Diabetes Self-Care Activities (SDSCA). Independent variable was SS (emotional/informational, tangible, affectionate, positive social interaction) measured using the Medical Outcomes Study (MOS) SS Scale. Structural equation modeling (SEM) was used to understand pathways between SS and glycemic control based on a theoretical model.

RESULTS

Tangible support was significantly associated with self-care (r = 0.16; p = 0.046) and affectionate support was marginally associated with glycemic control (r = 0.15; p = 0.08) for both men and women. Using SEM to test gender invariance, there was no statistically significant difference in the meaning of SS between men and women. However, unique invariances in responses occurred, including a stronger relationship between tangible support and self-care for women (r = 0.24; p = 0.061).

CONCLUSIONS

Of the four components of SS, tangible and affectionate support had the strongest influence on glycemic control. While affectionate support will improve glycemic control in both men and women, tangible support will improve self-care management, particularly in women.

The Associations of Loneliness and Social Support with Cognitive Impairment among Middle-Aged and Older Individuals with Diabetes

Diabetes mellitus is a chronic disease with significant morbidity and mortality and it is associated with poor cognitive performance in later life. This study seeks to determine the relationship between social support and cognitive function among participants with type 2 diabetes mellitus (T2DM). We used data from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, including participants with T2DM aged 45 and older (n = 4821). We examined different aspects of perceived social support, measured as structural social support (e.g., marital status), functional social support (having a caregiver in case of sickness or disability), and loneliness. We examined cognitive functioning using a six-item screener. Our results indicate that adults who felt lonely for 5-7 days per week had almost double the odds of cognitive impairment compared to those who didn't feel lonely. These results suggest that among middle-aged and older individuals with T2DM, interventions targeting lonely adults and which aim to reduce loneliness may combat some of the risks of cognitive decline.

Art Engagement and Risk of Type 2 Diabetes: Evidence From the English Longitudinal Study of Ageing

Objectives: To examine the prospective association between art engagement and the risk of type 2 diabetes. Methods: Adults aged ≥50 from the English Longitudinal Study of Ageing were asked about the frequency of art engagement, including going to the cinema, the art gallery or museum, and the theatre, a concert, or the opera. Cox proportional hazards regression models were used to examine the risk of type 2 diabetes associated with art engagement. Results: During a median follow-up of 12.2 years, we identified 350 cases of type 2 diabetes from 4,064 participants through interviews. After multivariable adjustment, compared with people who never went to the cinema, those going to the cinema frequently had a significantly lower risk of developing type 2 diabetes (HR = 0.61, 95% CI: 0.44-0.86). After further adjustment for socioeconomic factors, the association was slightly attenuated but remained statistically significant (HR = 0.65, 95% CI: 0.46-0.92). Similar results were found for going to the theatre, a concert, or the opera. Conclusion: Frequent art engagement may be associated with a lower risk of type 2 diabetes, which was independent of individuals' socioeconomic factors.

Social network interventions in the space of topological relationships between communities

A social network intervention is a process of intentionally altering a social network to achieve an objective. The objective in question may concern accelerating behaviour change or improving organisational performance. In this work we propose a novel model of social network interventions which considers topological properties of relationships existing between communities. Broadly speaking, topological properties of such relationships include properties described by natural language descriptions such as contains, partial overlap and disjoint. The proposed model provides an abstraction which in many cases is useful for solving problems involving social network interventions. We demonstrate this by simulating interventions on a number of hypothetical and real social networks in the domains of health and security.

Influence of Literacy, Self-Efficacy, and Social Support on Diabetes-Related Outcomes Following Hospital Discharge

Objective

To evaluate the relationship between health literacy, social support, and self-efficacy as predictors of change in A1c and readmission among hospitalized patients with type 2 diabetes (T2D).

Methods

This is a secondary analysis of patients with T2D (A1c >8.5%) enrolled in a randomized trial in which health literacy (Newest Vital Sign), social support (Multidimensional Scale of Perceived Social Support), and empowerment (Diabetes Empowerment Scale-Short Form) was assessed at baseline. Multivariable models evaluated whether these concepts were associated with A1c reduction at 12 weeks (absolute change, % with >1% reduction, % reaching individualized target) and readmission (14 and 30 days).

Results

A1c (N=108) decreased >1% in 60%, while individualized A1c target was achieved in 31%. After adjustment for baseline A1c and potential confounders, health literacy was associated with significant reduction in A1c (Estimate -0.21, 95% CI -0.40, -0.01, p=0.041) and >1% decrease in A1c (OR 1.37, 95% CI 1.08, 1.73, p=0.009). However, higher social support was associated with greater adjusted odds of reaching the individualized A1c target (OR 1.63, 95% CI 1.04, 2.55, p=0.32). Both higher empowerment (OR 0.23, 95% CI 0.08, 0.64, p=0.005) and social support (OR 0.57, 95% CI 0.36, 0.91, p=0.018) were associated with fewer readmissions by 14 days, but not 30 days.

Conclusion

The study indicates that health literacy and social support may be important predictors of A1c reduction post-discharge among hospitalized patients with T2D. Social support and diabetes self-management skills should be addressed and early follow-up may be critical for avoiding readmissions.

Sex and Gender Related Differences in Diabetic Kidney Disease

Diversity in sex and gender are important considerations in the pathogenesis, prognostication, research, and management of diabetic kidney disease (DKD). Sex and gender differences in the disease risk, disease-specific mechanisms, and outcomes in DKD may be attributed to biological differences between males and females at the cellular and tissue level, inconsistencies in the diagnostic and assessment tools used in chronic kidney disease and DKD, as well societal differences in the way men, women, and gender-diverse individuals self-manage and interact with health care systems. This review outlines key considerations related to the impact of sex on DKD, specifically elaborating on how they contribute to observed differences in disease epidemiology, pathogenesis, and treatment strategies. We also highlight the effect of gender on DKD progression and care.

Effectiveness and Cost-Effectiveness of Non-Pharmacological Interventions among Chinese Adults with Prediabetes: A Protocol for Network Meta-Analysis and CHIME-Modeled Cost-Effectiveness Analysis

Patients with prediabetes who are at a high risk of progressing to diabetes are recommended early-stage intervention, according to guidelines. Non-pharmacological interventions are effective and cost-effective for glycemic control compared with medicines. We aim to explore which non-pharmacological interventions have the greatest potential effectiveness, cost-effectiveness, and feasibility in community-based diabetes management in China. We will perform a systematic review and network meta-analysis to compare the effectiveness of included non-pharmacological interventions, then use Chinese Hong Kong Integrated Modeling and Evaluation (CHIME) to model the yearly incidence of complications, costs, and health utility for the lifetime. Published studies (only randomized controlled trials (RCTs) and cluster RCTs with at least one study arm of any non-pharmacological intervention) will be retrieved and screened using several databases. Primary outcomes included blood glucose, glycated hemoglobin, incidence of type 2 diabetes mellitus, and achievement of normoglycemia. Health utilities and cost parameters are to be calculated using a societal perspective and integrated into the modified CHIME model to achieve quality-adjusted life-year (QALY) estimates and lifetime costs. QALYs and incremental cost-effectiveness ratio will then be used to determine effectiveness and cost-effectiveness, respectively. Our study findings can inform improved diabetes management in countries with no intervention programs for these patients.

Effect and quality of couple-based interventions of middle-aged and older adults with type 2 diabetes mellitus: a scoping review

BACKGROUND

Studies have shown the existence of health concordance between patients with type 2 diabetes mellitus (T2DM) and their spouses, and also that spouses could influence the effect of self-management, benefiting patients' health. However, these studies are heterogeneous and the evidence is inconclusive.

OBJECTIVE

To synthesize evidence from published randomized controlled trials: the interventional effects and the quality of study performance, also to identify the research gap and the directions for future studies.

METHODS

We performed the scoping review by following the PRISMA-ScR guidance. We searched and examined the reports from MEDLINE, EMBASE, PsychInfo, CINAHL Plus by the pre-specified criteria. Key characteristics and information of eligible reports were extracted, analysed and synthesized comprehensively, and the results were presented in the form of words and diagrams.

RESULTS

We identified 5 reports from 4 studies out of 3479 records included. Qualified studies indicated a positive effect of couple-based interventions on couples' distress. Insufficient evidence on physiological health or health behaviours was identified owing to the small number of included studies and inconsistent assessment outcomes. The methodological quality across these studies was generally low due to inadequate reporting of study process and substantial biases.

CONCLUSIONS

Couple-based interventions for patients with T2DM showed small effects on the couple's distress while the effects of other outcomes were inconclusive. Future studies should strengthen methodologies by using standard measures of core diabetic outcomes, including detailed assessments of implementation process, and taking a dyadic approach to systematically examine the effects.

Effects of programs and interventions related to the social environment on childhood and adolescent obesity: A systematic search for and scoping review of natural experiments

Given the potential importance of social environment on obesity and to better understand their causal relationship amongst children and adolescents, this scoping review systematically searches for and evaluates programs and interventions using natural experiment designs. A majority of the studies assessing peer and social norm effects reported significant findings. Peer effects with nontrivial effect sizes likely have practical implications for interventions, while a strong conclusion cannot be drawn for social norm and neighborhood safety effects. Leveraging naturally occurring data might provide future research with a promising way of establishing a more robust causal inference for the topic of interest.

Social networks and type 2 diabetes: a narrative review

It has been known for decades that social networks are causally related to disease and mortality risk. However, this field of research and its potential for implementation into diabetes care is still in its infancy. In this narrative review, we aim to address the state-of-the-art of social network research in type 2 diabetes prevention and care. Despite the diverse nature and heterogeneity of social network assessments, we can draw valuable lessons from the available studies. First, the structural network variable 'living alone' and the functional network variable 'lack of social support' have been associated with increased type 2 diabetes risk. The latter association may be modified by lifestyle risk factors, such as obesity, low level of physical activity and unhealthy diet. Second, smaller network size and less social support is associated with increased risk of diabetes complications, particularly chronic kidney disease and CHD. Third, current evidence shows a beneficial impact of social support on diabetes self-management. In addition, social support interventions were found to have a small, favourable effect on HbA_1c values in the short-term. However, harmonisation and more detailed assessment of social network measurements are needed to utilise social network characteristics for more effective prevention and disease management in type 2 diabetes.

The Association of Family Support and Health Education with the Status of Overweight and Obesity in Patients with Type 2 Diabetes Receiving Outpatient Treatment: Evidence from a Hospital in Vietnam

This study aims to establish the association of family support and nutrition and health education by health workers with the status of overweight and obesity among patients with type 2 diabetes mellitus (T2DM) receiving outpatient treatment at a hospital. This descriptive cross-sectional study was conducted on 280 outpatients with type 2 diabetes at Bach Mai hospital from December 2019 to September 2020 by using assessments of anthropometric parameters and examining dietary habits and family support, as well as nutrition and health education and counseling by health workers. The prevalence of overweight and obesity in patients with T2DM was 35.4% (51.2% in men and 22.2% in women; P < .05). Patients never or rarely supported by their families or counseled by health workers were more vulnerable to overweight and obesity than those who frequently received support and counseling (OR = 1.41 vs 2.06; P < .05). Family support and counseling from health workers play a crucial role in promoting and sustaining healthy dietary habits and proper physical exercise in diabetic patients, contributing to their lowered risk of overweight and obesity.

Social Determinants of Diabetes-Related Preventable Hospitalization in Taiwan: A Spatial Analysis

Diabetes-Related Preventable Hospitalization (DRPH) has been identified as an important indicator of efficiency and quality of the health system and can be modified by social determinants. However, the spatial disparities, clustering, and relationships between DRPH and social determinants have rarely been investigated. Accordingly, this study examined the association of DRPH with area deprivation, densities of certificated diabetes health-promoting clinics (DHPC) and hospitals (DHPH), and the presence of elderly social services (ESS) using both statistical and spatial analyses. Data were obtained from the 2010-2016 National Health Insurance Research Database (NHIRD) and government open data. Township-level ordinary least squares (OSL) and geographically weighted regression (GWR) were conducted. DRPH rates were found to be negatively associated with densities of DHPC (β = -66.36, p = 0.029; 40.3% of all townships) and ESS (β = -1.85, p = 0.027; 28.4% of all townships) but positively associated with area deprivation (β = 2.96, p = 0.002; 25.6% of all townships) in both OLS and GWR models. Significant relationships were found in varying areas in the GWR model. DRPH rates are high in townships of Taiwan that have lower DHPC densities, lower ESS densities, and greater socioeconomic deprivation. Spatial analysis could identify areas of concern for potential intervention.

Impact and correlates of sub-optimal social support among patients in HIV care

Social support (SS) predicts health outcomes among patients living with HIV. We administered a brief, validated measure of SS, the Multifactoral Assessment of Perceived Social Support, within a patient-reported outcomes assessment of health domains in HIV care at 4 U.S. clinics in English and Spanish (n = 708). In univariate analysis, low SS was associated with poorer engagement in care, antiretroviral adherence, and health-related quality of life; current methamphetamine/crystal use, depression, anxiety, and HIV stigma (all p < 0.001); any use of either methamphetamines/crystal, illicit opioids, or cocaine/crack (p = 0.001), current marijuana use (p = 0.012), nicotine use (p = 0.005), and concern for sexually transmitted infection exposure (p = 0.001). High SS was associated with undetectable viral load (p = 0.031). Multivariate analyses found low SS independently associated with depression (risk ratio (RR) 3.72, 95% CI 2.93-4.72), lower adherence (RR 0.76, 95% CI 0.64-0.89), poor engagement in care (RR 2.05, 95% CI 1.44-2.96), and having more symptoms (RR 2.29, 95% CI 1.92-2.75). Medium SS was independently associated with depression (RR 2.59, 95% CI 2.00-3.36), poor engagement in care (RR 1.62, 95% CI 1.15-2.29) and having more symptoms (RR 1.75, 95% CI 1.44-2.13). SS assessment may help identify patients at risk for these outcomes.

The burden of treatment in people living with type 2 diabetes: A qualitative study of patients and their primary care clinicians

Background

The burden of treatment can overwhelm people living with type 2 diabetes and lead to poor treatment fidelity and outcomes. Chronic care programs must consider and mitigate the burden of treatment while supporting patients in achieving their goals.

Objective

To explore what patients with type 2 diabetes and their health providers consider are the workload and the resources they must mobilize, i.e., their capacity, to shoulder it.

Methods

We conducted focus groups comprised of 30 patients and 32 clinicians from three community health centers in Chile implementing the Chronic Care Model to reduce cardiovascular risk in patients with type 2 diabetes. Transcripts were analyzed using thematic content analysis techniques illuminated by the Minimally Disruptive Medicine framework.

Findings

Gaining access to and working with their clinicians, implementing complex medication regimens, and changing lifestyles burdened patients. To deal with the distress of the diagnosis, difficulties achieving disease control, and fear of complications, patients drew capacity from their family (mostly men), social environment (mostly women), lay expertise, and spirituality. Clinicians found that administrative tasks, limited formulary, and protocol rigidity hindered their ability to modify care plans to reduce patient workload and support their capacity.

Conclusions

Chronic primary care programs burden patients living with type 2 diabetes while hindering clinicians’ ability to reduce treatment workloads or support patient capacity. A collaborative approach toward Minimally Disruptive Medicine may result in treatments that fit the lives and loves of patients and improve outcomes.

Research Implications for Future Telemedicine Studies and Innovations in Diabetes and Hypertension-A Mixed Methods Study

(1) Background: The objective of this study was to identify, categorize and prioritize current implications for future research in the use telemedicine for diabetes and hypertension in order to inform policy and practice decisions. (2) Methods: An iterative mixed methods design was followed, including three consecutive steps: An updated umbrella review of telemedicine effectiveness, qualitative content analysis of extracted data on current research needs and a quantitative survey with practitioners and health care researchers in order to prioritize the identified needs. (3) Results: Overall, 32 included records reported on future research implications. Qualitative content analysis yielded five categories as well as subcategories, covering a need for high quality studies, comprehensive technology assessments, in-depth considerations of patients' characteristics, ethics and safety as well as implementation strategies. The online survey revealed that the most pressing future research needs are data security, patient safety, patient satisfaction, implementation strategies and longer follow-ups. Chi² statistics and t-tests revealed significant differences in the priorities of participants with and without experience in telemedicine use, evaluation and development. A factor analysis revealed six over-arching factors. (4) Conclusion: These results may help learning from mistakes previously made and may serve as key topics of a future telemedicine research agenda.

Mapping the Evidence on the Effectiveness of Telemedicine Interventions in Diabetes, Dyslipidemia, and Hypertension: An Umbrella Review of Systematic Reviews and Meta-Analyses

Background

Telemedicine is defined by three characteristics: (1) using information and communication technologies, (2) covering a geographical distance, and (3) involving professionals who deliver care directly to a patient or a group of patients. It is said to improve chronic care management and self-management in patients with chronic diseases. However, currently available guidelines for the care of patients with diabetes, hypertension, or dyslipidemia do not include evidence-based guidance on which components of telemedicine are most effective for which patient populations.

Objective

The primary aim of this study was to identify, synthesize, and critically appraise evidence on the effectiveness of telemedicine solutions and their components on clinical outcomes in patients with diabetes, hypertension, or dyslipidemia.

Methods

We conducted an umbrella review of high-level evidence, including systematic reviews and meta-analyses of randomized controlled trials. On the basis of predefined eligibility criteria, extensive automated and manual searches of the databases PubMed, EMBASE, and Cochrane Library were conducted. Two authors independently screened the studies, extracted data, and carried out the quality assessments. Extracted data were presented according to intervention components and patient characteristics using defined thresholds of clinical relevance. Overall certainty of outcomes was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool.

Results

Overall, 3564 references were identified, of which 46 records were included after applying eligibility criteria. The majority of included studies were published after 2015. Significant and clinically relevant reduction rates for glycated hemoglobin (HbA_1c; ≤−0.5%) were found in patients with diabetes. Higher reduction rates were found for recently diagnosed patients and those with higher baseline HbA_1c (>8%). Telemedicine was not found to have a significant and clinically meaningful impact on blood pressure. Only reviews or meta-analyses reporting lipid outcomes in patients with diabetes were found. GRADE assessment revealed that the overall quality of the evidence was low to very low.

Conclusions

The results of this umbrella review indicate that telemedicine has the potential to improve clinical outcomes in patients with diabetes. Although subgroup-specific effectiveness rates favoring certain intervention and population characteristics were found, the low GRADE ratings indicate that evidence can be considered as limited. Future updates of clinical care and practice guidelines should carefully assess the methodological quality of studies and the overall certainty of subgroup-specific outcomes before recommending telemedicine interventions for certain patient populations.

Does social support effect knowledge and diabetes self-management practices in older persons with Type 2 diabetes attending primary care clinics in Cape Town, South Africa?

BACKGROUND

In South Africa with one of the most rapidly ageing populations in Africa despite the demographic impact of the HIV/AIDS epidemic, diabetes is a major cause of morbidity and mortality. Self-management is challenging for all those with the condition but is likely to create a higher demand for those who may have existing co-morbidities associated with age, and long-standing chronic diseases.

OBJECTIVE

To determine the relationship of social support, especially that of family and friends with their self-management.

METHODS

This cross-sectional study was undertaken in the Cape Town metropole primary care clinics. The sample comprised 406 people drawn from four community health centres (CHC) that are served by Groote Schuur Hospital at the tertiary level.

RESULTS

Of the 406 participants, 68.5% were females, 60.5% were living with a family member, and almost half were married. The mean duration of diabetes from diagnosis was eight years. More than half (57.4%) had no or only primary education. Half the participants (50.2%) had poor knowledge level in relation to symptoms and complications of diabetes. Multivariable linear regression showed older age was associated with poor knowledge (®: -1.893, 95% CI-3.754; -0.031) and higher income was associated with self-management practice (®: 3.434, 95% CI 0.797; 6.070). Most participants received family support to follow aspects of diabetes self-management. The ordinal logistic regression indicated that family support was positively associated with the self-management practice score for following a diabetic meal plan, taking care of feet, physical activity, testing blood sugar and handling participants' feelings about being diabetic, but not for taking medication.

CONCLUSIONS

Consideration needs to be given to developing and testing education programmes that focus on needs of older people with diabetes and emphases the role of family and friends.

Effectiveness of non-pharmacological strategies in the management of type 2 diabetes in primary care: a protocol for a systematic review and network meta-analysis

INTRODUCTION

Despite the increasing number of drugs and various guidelines on the management of type 2 diabetes mellitus (T2DM), several patients continue with the disease uncontrolled. There are several non-pharmacological treatments available for managing T2DM, but various of them have never been compared directly to determine the best strategies.

OBJECTIVE

This study will evaluate the comparative effects of non-pharmacological strategies in the management of T2DM in primary care or community settings.

METHODS AND ANALYSIS

We will perform a systematic review and network meta-analysis (NMA), and will include randomised controlled trials if one of the following interventions were applied in adult patients with T2DM: nutritional therapy, physical activity, psychological interventions, social interventions, multidisciplinary lifestyle interventions, diabetes self-management education and support (DSMES), technology-enabled DSMES, interventions delivered only either by pharmacists or by nurses, self-blood glucose monitoring in non-insulin-treated T2DM, health coaching, benchmarking and usual care. The primary outcome will be glycaemic control (glycated haemoglobin (HbA1c) (%)), and the secondary outcomes will be weight loss, quality of life, patient satisfaction, frequency of cardiovascular events and deaths, number of patients in each group with HbA1c <7, adverse events and medication adherence. We have developed search strategies for Embase, Medline, Latin American and Caribbean Health Sciences Literature, Cochrane Central Register of Controlled Trials, Trip database, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature Australasian Medical Index and Chinese Biomedical Literature Database. Four reviewers will assess the studies for their eligibility and their risk of bias in pairs and independently. An NMA will be performed using a Bayesian hierarchical model, and the treatment hierarchy will be obtained using the surface under the cumulative ranking curve. To determine our confidence in an overall treatment ranking from the NMA, we will follow the Grading of Recommendations Assessment, Development and Evaluation approach.

ETHICS AND DISSEMINATION

As no primary data collection will be undertaken, no formal ethical assessment is required. We plan to present the results of this systematic review in a peer-reviewed scientific journal, conferences and the popular press.

The Association between Diabetes-Related Distress and Medication Adherence in Adult Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Study

BACKGROUND

Type 2 diabetes mellitus (T2DM) is a major public health problem associated with distress. T2DM can affect health outcomes and adherence to medications. Little is however known about the association between diabetes distress and medication adherence among patients with T2DM in Ghana.

OBJECTIVE

The objective of the present study is twofold: to estimate distress associated with T2DM and to examine its association with medication adherence.

METHODS

A hospital-based cross-sectional study was conducted among 188 patients with T2DM recruited from a diabetes specialist outpatient clinic at the Pantang Hospital in Accra, Ghana. Data were obtained using the Problem Areas In Diabetes (PAID) scale and the Medication Adherence Report Scale.

RESULTS

The findings showed that about 44.7% of the patients showed high levels of diabetes-related distress. Poor adherence to medications was recorded in 66.5% of the patients. Patients who were highly distressed had 68% lower odds of adhering to their medications compared to those who were not (OR: 0.32, 95% CI: 0.15-0.65). A principal component analysis revealed four areas of T2DM distress which were conceptualized as negative emotions about diabetes, dietary concerns and diabetes care, dissatisfaction with external support, and diabetes management helplessness.

CONCLUSION

Our findings suggest that diabetes distress is a significant determinant of medication adherence behaviour in patients with T2DM. Thus, incorporating routine screening for distress into the standard diabetes care within the Ghanaian health system and having health practitioners adopt holistic approaches to diabetes management will be important context-specific interventions to improve adherence and health outcomes of people living and coping with T2DM.

Effectiveness of interventions involving social networks for self-management and quality of life in adults with diabetes: a systematic review protocol

OBJECTIVE

The purpose of this systematic review is to explore the effect of interventions involving social networks on self-management and quality of life in adults with diabetes.

INTRODUCTION

There is growing evidence that interventions involving social networks have a positive impact on people with diabetes through social support and social participation. However, the existing literature or protocols relate to only one type of diabetes, a certain population, or one type of intervention involving social networks. This study will comprehensively assess the impact of interventions involving social networks on self-management and quality of life for all types of diabetes.

INCLUSION CRITERIA

This study will consider studies that compare interventions involving the social networks (families, friends and peers) of adults with all types of diabetes with interventions that do not involve social networks.

METHODS

We plan to collect relevant randomized and non-randomized controlled trials for systematic evaluation and meta-analysis by searching PubMed, Embase, Web of Science, CINAHL Complete, Cochrane Central Register of Controlled Trials, ProQuest Dissertations and Theses, and Google Scholar. Studies published in English from database inception to the present will be included. After the search, two researchers will independently screen the literature according to inclusion and exclusion criteria, evaluate the selected literature critically and extract the relevant data required, then meta-analysis will be performed using Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information.

Social network interventions for health behaviours and outcomes: A systematic review and meta-analysis

BACKGROUND

There has been a growing interest in understanding the effects of social networks on health-related behaviour, with a particular backdrop being the emerging prominence of complexity or systems science in public health. Social network interventions specifically use or alter the characteristics of social networks to generate, accelerate, or maintain health behaviours. We conducted a systematic review and meta-analysis to investigate health behaviour outcomes of social network interventions.

METHODS AND FINDINGS

We searched eight databases and two trial registries from 1990 to May 28, 2019, for English-language reports of randomised controlled trials (RCTs) and before-and-after studies investigating social network interventions for health behaviours and outcomes. Trials that did not specifically use social networks or that did not include a comparator group were excluded. We screened studies and extracted data from published reports independently. The primary outcome of health behaviours or outcomes at ≤6 months was assessed by random-effects meta-analysis. Secondary outcomes included those measures at >6-12 months and >12 months. This study is registered with the International Prospective Register of Systematic Reviews, PROSPERO: CRD42015023541. We identified 26,503 reports; after exclusion, 37 studies, conducted between 1996 and 2018 from 11 countries, were eligible for analysis, with a total of 53,891 participants (mean age 32.4 years [SD 12.7]; 45.5% females). A range of study designs were included: 27 used RCT/cluster RCT designs, and 10 used other study designs. Eligible studies addressed a variety of health outcomes, in particular sexual health and substance use. Social network interventions showed a significant intervention effect compared with comparator groups for sexual health outcomes. The pooled odds ratio (OR) was 1.46 (95% confidence interval [CI] 1.01-2.11; I2 = 76%) for sexual health outcomes at ≤6 months and OR 1.51 (95% CI 1.27-1.81; I2 = 40%) for sexual health outcomes at >6-12 months. Intervention effects for drug risk outcomes at each time point were not significant. There were also significant intervention effects for some other health outcomes including alcohol misuse, well-being, change in haemoglobin A1c (HbA1c), and smoking cessation. Because of clinical and measurement heterogeneity, it was not appropriate to pool data on these other behaviours in a meta-analysis. For sexual health outcomes, prespecified subgroup analyses were significant for intervention approach (p < 0.001), mean age of participants (p = 0.002), and intervention length (p = 0.05). Overall, 22 of the 37 studies demonstrated a high risk of bias, as measured by the Cochrane Risk of Bias tool. The main study limitations identified were the inclusion of studies of variable quality; difficulty in isolating the effects of specific social network intervention components on health outcomes, as interventions included other active components; and reliance on self-reported outcomes, which have inherent recall and desirability biases.

CONCLUSIONS

Our findings suggest that social network interventions can be effective in the short term (<6 months) and longer term (>6 months) for sexual health outcomes. Intervention effects for drug risk outcomes at each time point were not significant. There were also significant intervention effects for some other health outcomes including alcohol misuse, well-being, change in HbA1c, and smoking cessation.

A Systematic Review of Community Health Center Based Interventions for People with Diabetes

Community health centers (CHCs) focus on serving socioeconomically disadvantaged populations with heightened chronic disease burden, making CHCs an ideal setting for implementing diabetes care programs that target vulnerable populations. We aimed to synthesize evidence concerning the effects of CHC interventions in people with diabetes. To do this, four electronic databases were searched, including PubMed, EMBASE, CINAHL, and Scopus, and hand searches of reference collections were undertaken to identify intervention trials published in English. We screened 892 unique titles and abstracts. Two reviewers then independently evaluated 221 full-text articles. We discovered 29 articles met our eligibility criteria for inclusion. We found 27 unique studies with two companion articles. Seventeen studies were randomized controlled trials and the majority had a higher proportion of female and racial/ethnic minorities in the study sample. CHC interventions often involved either one-on-one or group education sessions supplemented by a phone follow-up that were delivered by health providers, nutritionists, or community health workers. CHC interventions using education sessions combined with follow up via phone generally resulted in significant improvements in hemoglobin A1C, while sole telephone-based education studies showed no significant improvements. CHC interventions had no significant effects on physical activity in all six studies that examined the outcome. Overall, we found that CHC interventions were in general effective in improving glucose control when using face-to-face interactions in low-income, underserved, and racial and ethnic minority patients with diabetes. Evidence was limited, however, in regards to other outcomes which suggests the need for continued evaluations of CHC intervention models.

Actions to influence the care network of home-dwelling elderly people: A qualitative study

Positive impact of care networks of home-dwelling elderly people may be based on several network mechanisms: navigation to resources, negotiation between participants and contagion of behaviours. Little is known about actions of participants-elderly people, informal caregivers or formal care providers-to activate such mechanisms and generate support. Aim of this study was to identify actions in relation to these network mechanisms. A cross-sectional qualitative study of 48 interviews with home-dwelling elderly people, informal caregivers and formal care providers in the eastern parts of the Netherlands was conducted between March and September 2016. A framework analysis on network mechanisms categorised actions. Actions were reviewed by network party and compared between networks to explore relations between actions and networks. Results showed that participants navigated through existing relations to seek support. Actions on negotiation were aimed at ameliorating existing relations. Few examples and no actions on contagion of behaviours were found. Actions seemed driven by incidents and existing relations. Elderly people rarely initiated actions, informal caregivers felt hampered by their position in the network. Consistent patterns of relations between actions and network characteristics did not emerge. We concluded that the full potential of network-based support of elderly people is probably underused. Particularly promising seem: navigating the neighbourhood for new informal care, using opposite opinions as a catalyst for change and bringing quality of life and dilemma's into dialogue in the network.

Development and content validation of the Multifactoral assessment of perceived social support (MAPSS), a brief, patient-reported measure of social support for use in HIV care

Low perceived social support (SS) negatively impacts health outcomes. We developed a measure of perceived SS for use in HIV care. We sought and categorized legacy items, selecting strongest items within categories. We elicited SS concepts from patients in English/Spanish, coded transcripts to match item pool content, and developed new items for salient unrepresented content. In focus groups, patients prioritized highly-matched items. We conducted cognitive interviews on high-priority items, and validity testing on final items against two legacy measures. From interviews (n = 32), we matched the following concepts: sense of belonging/inclusion; communication; emotional support; feeling accepted by others as a person; companionship; and practical support. We identified a new concept: support from friends/family in remaining healthy. Focus groups (n = 23) prioritized emotional support, communication, and support to remain healthy. Cognitive interviews (n = 30) found items were well-understood. The final 8-item measure performed well with patients (n = 708), with good construct validity. We used an Item Response Theory program to create a 3-item Short Form version of the measure, which captures 96% of patients indicating low social support. We developed the Multifactoral Assessment of Perceived Social Support (MAPSS) and Short Form (MAPSS-SF); brief, clinically relevant, sufficiently unidimensional measures of SS for use in HIV care.

Effects of a Family-Based Diabetes Intervention on Family Social Capital Outcomes for Mexican American Adults

PURPOSE

The purpose of the study is to test the effects of a culturally tailored family-based self-management education and social support intervention on family social capital with Mexican American (MA) adults with type 2 diabetes (T2DM) and their family member.

METHODS

Using a 2-group, experimental repeated-measures design, 157 dyads were randomly assigned to an intervention (group education and social support, home visits, and telephone calls) or a wait list control group. Data were collected at baseline, immediately postintervention (3 months), and 6 months postintervention. A series of 2 × 3 repeated-measures analyses of variance with interaction contrasts were used to test the hypotheses regarding the differential effects on family social capital.

RESULTS

Social capital outcomes included social integration, social support, and family efficacy. Social integration scores, high for family members and friends and low for community engagement, did not change over time for participants or family members. Participants perceived high support from family for physical activity with an immediate increase postintervention and moderate sabotage for healthy eating with no change over time. A sustained intervention effect was noted for family efficacy for general health and total family efficacy in participants and family members.

CONCLUSIONS

This family-based culturally tailored intervention demonstrated the potential to improve social capital, specifically social support for physical activity and family efficacy for diabetes management for MA adults with T2DM. Ongoing research that examines the family as a critical context in which T2DM self-management occurs and that targets strategies for sustained family social capital outcomes for T2DM is needed.

Family Support and Diabetes: Patient's Experiences From a Public Hospital in Peru

Family support is crucial for managing chronic conditions but it is often overlooked when designing behavioral interventions in type 2 diabetes mellitus (T2DM). As part of the formative phase of a feasibility randomized control trial (RCT), we conducted 20 semistructured interviews with people with T2DM from Lima, Peru. Based on such results, we describe the support people with T2DM receive from their families and the role that such support has in their efforts to implement diabetes management practices. We learned that participants receive support from family members, but mostly from their spouses and children. Their relatives encourage them and motivate them to fight for their health, they also provide instrumental support by preparing healthy meals, reminding them to take medications, and sharing physical activity. Participants also reported controlling actions which were not always "well received." Thus, any intervention supporting self-management practices need to work with key family members. We support the literature that suggests that interventions should target family members to ensure improved T2DM self-management practices.

Relationship style and glycaemic control in women with type 2 diabetes: The mediating role of psychological distress

This study examined whether depressive symptoms and/or diabetes distress mediate the association between relationship style and glycaemic control in women with diabetes. Seventy-five women with type 2 diabetes completed the Relationship Questionnaire. Participants endorsing "secure" or "preoccupied" adult attachment were combined into the interactive relationship style and "dismissing/avoidant" or "fearful" adult attachment were combined into the independent relationship style. Glycaemic control was a latent variable composed of A1c and 48-hr continuously measured glucose. Diabetes distress was assessed with the Problem Areas in Diabetes scale and depressive symptoms with the Center for Epidemiological Studies Depression scale. A parallel multiple mediation model with relationship style as the independent variable, glycaemic control as the dependent variable, and Problem Areas in Diabetes and Center for Epidemiological Studies Depression scale as mediators, tested indirect effects. Bias-corrected bootstrap with 10,000 replications was used to construct 95% confidence intervals. The indirect association of relationship style with glycaemic control through diabetes distress was significant (effect = -0.09, p = .036, 95CI = -0.19-0.01), but through depressive symptoms was not. A model testing the indirect association of relationship style with diabetes distress through glycaemic control was not significant. Results suggest that relationship style is associated with glycaemic control through diabetes distress in women with type 2 diabetes.
