Subjective wellbeing as a determinant of glycated hemoglobin in older adults: longitudinal findings from the English Longitudinal Study of Ageing

Spousal Involvement in Collaborative Management and Glycemic Behavior Change among Patients with Diabetes Mellitus: A Systematic Review

Introduction

The marked increase in the number of individuals with diabetes mellitus (DM) worldwide each year has resulted in the importance of the spouse's contribution to the promotion and support of patient self-management programs.

Objectives

This study aimed to systematically explore the role or involvement of spouses in collaborative management and glycemic behavior change in DM.

Methods

Five databases including Scopus, PubMed, Cumulative Index of Nursing and Allied Health Literature, SAGE, and Web of Science were reviewed for relevant articles retrieved from 2017 to 2022. Literature search used keywords, including "Spouse," "Support," "Self-management," "Glycemic Control," and "Diabetes mellitus." The Joanna Briggs Institute guidelines were used for appraisal review of journals. The component of partner support in the self-management of patients with DM is associated with an increase in the patient's glycemic level.

Results

Twenty-five studies were identified that describe the different spousal roles and strategies in the promotion and support of DM management. Overall, spouses' involvement positively impacted healthy diets, higher self-efficacy, improved quality of psychological well-being, increased perceived support, and changes in glycemic-influenced behavior. Adaptation in the spouse patient relationship including maintaining cohesiveness can result in positive coping is essential in normalizing and contextualizing the chronic condition of DM. Partner-based collaboration is important for diabetes management, overcoming management barriers, and generating communal coping.

Conclusion

This systematic review observed that the involvement of a spouse is important in improving collaborative management and results in better glycemic behavior in patients with DM. A better understanding of the relationship between spousal involvement, coping strategies, and adherence in daily management and the subsequent use of this information are highly useful for creating targeted and effective interventions.

Association Between Optimism and Incident Stroke Among Stroke Survivors: Findings From the English Longitudinal Study of Ageing

BACKGROUND

Personality has been implicated in stroke death. However, the role of personality in stroke incidence is unclear.

PURPOSE

Our primary aim was to investigate associations between optimism, determination, control, and the "Big Five" personality traits on incident stroke. A secondary aim was to assess the potential mediating role of health behaviors in the personality-stroke relationship.

METHODS

A total of 3,703 stroke-free participants from the English Longitudinal Study of Ageing provided data on personality using the Midlife Development Inventory at Wave 5 (2010/11). Self-reported incident stroke was assessed from Waves 6 to 8 (2012-2017). Associations were modeled using discrete-time survival proportional odds logistic models. Analyses were adjusted for sociodemographic factors, history of other cardiometabolic diseases, and health behaviors.

RESULTS

Over 6 years follow-up there were 125 incident strokes. Higher optimism (hazard ratio [HR] = 0.66; 95% confidence interval [CI] 0.53, 0.82), openness (HR = 0.72; 95% CI 0.53, 0.98), and conscientiousness (HR = 0.59; 95% CI 0.42, 0.84) were associated with reduced incident stroke risk in unadjusted models. After adjustment for sociodemographic factors and history of cardiometabolic disease, only the association between optimism and incident stroke remained significant (HR = 0.72; 95% CI 0.57, 0.92). The effect of optimism remained significant in a final model adjusting for health behaviors (HR = 0.75; 95% CI 0.60, 0.96). There was evidence of a small but significant mediating effect of physical activity.

CONCLUSIONS

Higher trait optimism was associated with reduced stroke risk. This association was partially mediated by physical activity albeit the effect was small, and caution warranted inferring causality. The interplay of personality, behavior, and clinical risk factors in stroke incidence and survivorship needs further investigation.

A model to forecast the two-year variation of subjective wellbeing in the elderly population

BACKGROUND

The ageing global population presents significant public health challenges, especially in relation to the subjective wellbeing of the elderly. In this study, our aim was to investigate the potential for developing a model to forecast the two-year variation of the perceived wellbeing of individuals aged over 50. We also aimed to identify the variables that predict changes in subjective wellbeing, as measured by the CASP-12 scale, over a two-year period.

METHODS

Data from the European SHARE project were used, specifically the demographic, health, social and financial variables of 9422 subjects. The subjective wellbeing was measured through the CASP-12 scale. The study outcome was defined as binary, i.e., worsening/not worsening of the variation of CASP-12 in 2 years. Logistic regression, logistic regression with LASSO regularisation, and random forest were considered candidate models. Performance was assessed in terms of accuracy in correctly predicting the outcome, Area Under the Curve (AUC), and F1 score.

RESULTS

The best-performing model was the random forest, achieving an accuracy of 65%, AUC = 0.659, and F1 = 0.710. All models proved to be able to generalise both across subjects and over time. The most predictive variables were the CASP-12 score at baseline, the presence of depression and financial difficulties.

CONCLUSIONS

While we identify the random forest model as the more suitable, given the similarity of performance, the models based on logistic regression or on logistic regression with LASSO regularisation are also possible options.

Links of positive affect and stress to HbA1c: a prospective longitudinal study

While affect is linked to a number of diabetes outcomes, the specific role of positive affect (PA) in HbA1c remains unclear. The present study examined whether PA prospectively predicted lower HbA1c among adults with type 2 diabetes and whether this relation was moderated by stress. Participants were 123 adults (44.7% female; 60.2% White, 39.8% Black) recently diagnosed with type 2 diabetes. Perceived stress, diabetes-specific distress, and PA were assessed at baseline; HbA1c was assessed at baseline (T1), six months (T2), and five years (T3). PA was cross-sectionally associated with lower HbA1c at T1 and prospectively predicted lower HbA1c at T3. PA interacted with both measures of T1 stress to predict T1 HbA1c, and PA interacted with T3 perceived stress to predict T3 HbA1c. Interactions were consistent with stress buffering. Sensitivity analyses attentuated findings, but robust evidence remained for PA as a protective factor for blood glucose five years later and for a stress-buffering effect of PA on diabetes-specific distress. Findings suggest PA may be a clinically useful indicator among adults with type 2 diabetes and may be particularly important for those experiencing the greatest stress from their disease.

Beyond depression: correlates of well-being in young adult survivors of childhood cancers

PURPOSE

This study investigated the correlates of well-being with psychosocial and clinical factors in young adult childhood cancer survivors (YACCS) above and beyond depressive symptoms.

METHODS

Participants were from the Project Forward Cohort, a population-based study of young adult survivors of childhood cancers. Participants (n = 1166, Mage = 25.1 years) were recruited through the Los Angeles Cancer Surveillance Program (Cancer Registry covering Los Angeles County). A majority received a diagnosis of leukemia (36.1%) or lymphoma (21.7%). Participants completed self-reported questionnaires at one timepoint. Multiple regression analyses were performed with well-being as the outcome variable and psychosocial and clinical variables (social support, sense of adulthood, posttraumatic growth, treatment intensity, and self-rated health) as the independent variables. Covariates included demographics (age, gender, relationship status, race/ethnicity) and depressive symptoms.

RESULTS

In the multivariable model, posttraumatic growth, social support, sense of adulthood, and self-rated health were significantly associated with well-being (all ps < .05), when controlling for depressive symptoms. Treatment intensity and years since diagnosis were not significantly associated with well-being, when controlling for depressive symptoms.

CONCLUSIONS

There are unique correlates of well-being above and beyond depressive symptoms among YACCS. This finding illuminates individual differences that may be associated with well-being and provides targets for intervention.

IMPLICATIONS FOR CANCER SURVIVORS

Psychosocial interventions and survivorship care for YACCS should consider the broad aspects of well-being, independent of depressive symptoms.

Enjoyment of life predicts reduced type 2 diabetes incidence over 12 years of follow-up: findings from the English Longitudinal Study of Ageing

BACKGROUND

Subjective well-being appears to be associated with reduced risk of type 2 diabetes (T2D). However, it is unknown whether this association is similar across different types of well-being. We examined the relationship between hedonic and eudaimonic well-being and incident T2D, and explored the role of sociodemographic, behavioural and clinical factors in these associations.

METHODS

We used data from 4134 diabetes-free participants from the English Longitudinal Study of Ageing (mean age =64.97). Enjoyment of life and purpose in life were assessed using items from the CASP-19 to reflect hedonic and eudaimonic well-being, respectively. Participants reported T2D diagnosis over 12 years. We used Cox proportional hazards regression analyses and also explored the percentage of association explained by different covariates.

RESULTS

Results revealed a protective role for enjoyment of life in T2D rate adjusting for sociodemographic (age, sex, wealth, ethnicity, marital status), behavioural (physical activity, smoking, alcohol consumption, body mass index) and clinical (hypertension, coronary heart disease and glycated haemoglobin) characteristics (HR =0.93, p=0.021, 95% CI (0.87, 0.99)). Sociodemographic, behavioural and clinical factors accounted for 27%, 27% and 18% of the association, respectively. The relationship between purpose in life and T2D was non-significant (adjusted HR =0.92, p=0.288, 95% CI (0.78, 1.08)).

CONCLUSION

This study illustrates how the link between subjective well-being and T2D varies between well-being components. It also demonstrates that sociodemographic, behavioural and clinical factors partially explain this association. Intervention studies examining whether changes in enjoyment of life can help delay T2D onset are warranted.
