Social Inclusion Predicts Lower Blood Glucose and Low-Density Lipoproteins in Healthy Adults

Association between Levels of Loneliness, Laboratory Measurements, and Behavioral Aspects in a Primary Care Setting in Crete, Greece

This paper examines potential associations of loneliness with laboratory data and specific psychosocial and behavioral attitudes. The sample collection took place in an urban Primary Health Care unit between May and July 2023, consecutively, and once exclusion criteria were implemented. Participants were aged between 40 and 75 years. Routine laboratory test results upon study initiation and six months before were used. The University of California, Los Angeles (UCLA), Loneliness Scale (Version 3), blood glucose, serum lipids, Fibrosis-4 index, and Creatinine Clearance (CrCl) were assessed through hierarchical multiple logistic regression analysis. Based on full model (3rd) analysis, those who were engaged in an individual sport or activity or had contacts with more friends presented significantly lower odds for increased loneliness levels (odds ratio (OR): 0.28 [95% confidence interval (CI) 0.09-0.91], p = 0.034 and OR: 0.76 [95%CI 0.66-0.88], p < 0.001, respectively). The consumption of alcohol was associated with increased loneliness (OR: 5.55 [95%CI 1.42-21.63], p = 0.014). Elevated triglyceride levels were linked with moderate or no loneliness (OR: 0.20 [95%CI 0.05-0.83], p = 0.026), while an increased LDL/HDL atherosclerotic index was related to increased subjective loneliness (OR: 4.50 [95%CI 1.12-18.13], p = 0.035). The need for holistic approaches-involving primary care personnel-in understanding and addressing loneliness, recognizing its multifaceted nature as well as the diverse factors that contribute to this issue, is considered challenging.

Modeling Adolescent Social Inclusion to Improve School Completion

Enhancing social inclusion in young people could increase engagement in education, yet few longitudinal studies have examined this relationship. This study aimed to identify whether social inclusion in an Australian adolescent sample predicted high school completion three years later. Using state-representative data from the International Youth Development Study, two waves of the youngest cohort (51.6% female and 94.6% Australian born) during mid-adolescence (n = 825, M_age = 15.99, SD = 0.39) and post-secondary school (n = 809, M_age = 19.03, SD = 0.44) were analyzed. Factor analysis identified a 4-factor structure that represented an overarching social inclusion construct: (1) Citizenship, (2) Connectedness to Community, (3) Connectedness to Family, and (4) Connectedness to and Participation in School. Multivariate regression analyses indicated higher social inclusion levels in mid-adolescence predicted an increased likelihood of high school completion three years later. The implementation of strategies that incorporate the enhancement of social inclusion may improve educational outcomes for young people.

Lipidemic Effects of Kissing are Mediated by Stress: Results from a National Probability Sample

Previous studies have identified associations between affectionate communication and blood lipid levels but been limited by small, homogenous samples and failed replication attempts. Moreover, no study has tested the prediction derived from affection exchange theory that stress mediates the association between affectionate behavior and health. Using secondary analyses of data from the Midlife in the United States (MIDUS) Refresher study Biomarker Project, this paper remedies these limitations by testing the prediction that stress mediates the association between kissing and serum levels of triglycerides, high-density lipoproteins, and low-density lipoproteins using a large probability sample of U.S. American adults (N = 863). Results indicate significant indirect effects of kissing frequency on triglycerides and high-density lipoproteins for participants who reported kissing seven or more times in the previous month.

ComparativeStudyofCRHMicroinjections Into PVN and CeA Nuclei on Food Intake, Ghrelin, Leptin, and Glucose Levels in Acute Stressed Rats

Introduction:

Corticotropin-Releasing Hormone (CRH) is involved in stress and energy homeostasis. On the other hand, CRH receptors also exist within the paraventricular nucleus (PVN) and Central Amygdala (CeA) nuclei. The present study compared the effect of CRH microinjections into PVN and CeA on three consecutive hours and cumulative food intake, internal regulatory factors of food intake, such as serum leptin and ghrelin, as well as blood glucose levels in rats under different acute psychological (Social Stress [SS] and Isolation Stress [IS] group) stresses.

Methods:

Sixty-six male Wistar rats were randomly allocated to 11 groups: Control, Sham, CRH-PVN, CRH-CeA, SS, IS, SS-CRH-PVN, SS-CRH-CeA, IS-CRH-PVN, and IS-CRH-CeA groups. The CRH (2 µg/kg in 0.5 µL saline) was injected into PVN and CeA nuclei in rats under everyday, acute social stress and isolation stress conditions.

Results:

Acute isolation and social stresses did not affect cumulative food intake. Whereas isolation stress led to changes in both leptin and glucose levels, social stress reduced only glucose levels. Cumulative food intake significantly decreased under acute CRH injection into the CeA and particularly into the PVN. Blood glucose significantly reduced in all the groups receiving CRH into their CeA.

Conclusion:

The PVN played a more important role compared to CeA on food intake. These nuclei probably employ different mechanisms for their effects on food intake. Besides, it seems that exogenously CRH injection into the PVN probably had a more anorectic effect than naturally activated CRH by stresses. Acute isolation stress had a greater impact than social stress on leptin level and cumulative food intake. Thus, elevated food intake related to leptin compared to ghrelin and glucose levels in the CRH-PVN group under acute social stress.

A systematic review of the relationships among psychosocial factors and coping in adults with type 2 diabetes mellitus

Type 2 diabetes mellitus contributes to poor health outcomes including mortality, yet there is a gap in the literature when seeking to understand the influence of psychosocial factors on coping in this population. The paper presents a systematic review of quantitative studies that examined relationships among psychosocial determinants and coping in adults with type 2 diabetes. This review is the second layer of knowledge discovery for the concept, “Taking on a life-altering change is a rhythmical journey of experiencing ups and downs on the way to acceptance.” The life-altering change was determined to be a diagnosis of type 2 diabetes, the journey is the ups and downs of coping with the diagnosis as people work toward acceptance of type 2 diabetes. The review includes a synthesis of findings from 22 quantitative studies of psychosocial factors and coping in adults with type 2 diabetes. Anxiety, depression, stress, and diabetes distress were identified as key influential psychosocial factors. Increased social support was inversely related to emotional distress and coping styles were related to social well-being, psychological health, and physical health outcomes. The positive coping style of problem-focused coping was linked to improved psychological and physical health. Emotional responses to diagnosis were related to depression and anxiety. Negative coping styles of resignation, protest, or isolation were higher in women and linked to poorer quality of life, while avoidance was linked to increased diabetes-related distress and depressive symptoms.

Social inclusion and its interrelationships with social cognition and social functioning in first-episode psychosis

AIM

People with psychosis are at risk of social exclusion. Research is needed in this area due to the lack of direct measurement of social inclusion, which becomes salient in adolescence and is relevant to first-episode psychosis (FEP; the onset of which typically occurs during or shortly after adolescence). Social inclusion may be impacted by impaired social cognition and social functioning, which are related features observed in psychosis. The aim of this study was to explore interrelationship(s) between social cognition, social functioning and social inclusion in FEP while controlling for symptomatology (positive, negative and depressive symptoms) and demographic characteristics.

METHODS

A series of cross-sectional hierarchical multiple regressions were conducted to examine whether: social cognition (theory of mind, emotion recognition) predicted social functioning; social functioning predicted social inclusion, and whether social functioning mediated the relationship between social cognition and social inclusion in people aged 15 to 25 (M = 20.49, SD = 2.41) with FEP (N = 146). Age, sex, premorbid IQ, positive and negative psychotic symptoms and depression were control variables.

RESULTS

Poor facial emotion recognition (β = -.22, P < .05) and negative symptoms (β = -.45, P < .001) predicted lower social functioning. Role-specific social functioning (ie, current employment) predicted greater social inclusion (β = .17, P < .05). Higher depression symptomatology predicted lower social inclusion (β = -.43, P < .001). Social functioning did not mediate the relationship between social cognition and inclusion. Psychotic symptoms were unrelated to social inclusion.

CONCLUSIONS

Employment and depression may influence social inclusion somewhat independently of psychotic symptomatology in FEP. Inferences should be viewed with caution given this study did not involve longitudinal data.
