Loneliness in Primary Care Patients: Relationships With Body Mass Index and Health Care Utilization

Investigating the relationship between early cardiovascular disease markers and loneliness in young adults

Loneliness is recognised as a risk factor for cardiovascular disease development. However, it is unclear whether loneliness itself or other closely related mental health symptoms, such as depression and social anxiety, are associated with the development of cardiovascular disease. In the present study, we examined the relationship between loneliness and several early cardiovascular disease markers in young adults, after controlling for depression and social anxiety. Sixty-six young adults (18-35 years old, Mage = 22.70; 75.8% females) completed psychological questionnaires and took part in several physiological tests assessing cardiovascular health (e.g., vascular function). Results revealed higher loneliness was significantly associated with shorter pulse transit time (β = - 0.70, p = 0.002; shorter pulse transit time is a subclinical marker for arterial stiffness). Additionally, results show that while loneliness and depression were both related to vascular dysfunction in young adults, the underlining physiological mechanisms through which they affect vascular function may be different. Specifically, higher loneliness was associated with increased arterial stiffness, whereas depression was associated with increased endothelial dysfunction (β = - 0.43, p = 0.04). Our findings indicate that presence of loneliness and depression in young adults may be accompanied by early indicators of poor cardiovascular health, such as arterial stiffness and endothelial dysfunction. Results from the study further support the link between loneliness and cardiovascular disease development.

Loneliness and its cross-sectional associations with health, health behaviours, and perceptions in Finnish patients with overweight or obesity taking part in the Healthy Weight Coaching

OBJECTIVE

To investigate cross-sectional associations between loneliness and health, health behaviours, and perceptions in Finnish individuals with overweight or obesity (BMI ≥25 kg/m2).

METHODS

We used baseline data from patients participating, in 2016-2022, in a real-life digital 12-month weight management program known as Healthy Weight Coaching. Patients completed several questionnaires such as those related to loneliness, healthcare resource utilization, physical activity, and life satisfaction. BMI was computed based on self-reported weight and height. In addition to investigating individual health variables, we studied the association between loneliness and factor-analysis-derived health and wellbeing clusters.

RESULTS

Data were available from 2000 individuals (16.7% men, median age 48 years, median BMI 39.2 kg/m2). Altogether, 11.6%, 42.4%, and 46.0% reported feeling lonely, somewhat lonely, and not lonely, respectively. Feeling lonely was associated with higher BMI, greater healthcare resource utilization, lower life satisfaction, burdensomeness of life, more negative perceptions related to obesity and to the upcoming coaching, lower daytime energy, and reduced 20-min brisk walk results, a measure of functional capacity. Of the five factor-analysis-derived clusters, loneliness was adversely associated with "Life satisfaction" [lonely, 0.337 (0.270-0.421), p < 0.001; somewhat lonely, 0.545 (0.475-0.625), p < 0.001]. Moreover, loneliness associated with "Negative perceptions of obesity/daytime fatigue" [lonely, 4.627 (3.391-6.314), p < 0.001; somewhat lonely 2.021 (1.694-2.412), p < 0.001], and "Obesity/low physical activity" [lonely, 1.474 (1.105-1.966), p = 0.008; somewhat lonely, 1.220 (1.019-1.460), p = 0.030].

CONCLUSIONS

Loneliness had several untoward associations with health, health behaviours, and perceptions. Further research should explore the intricate relationship between obesity, loneliness, and physical and psychosocial health.

The Association of Loneliness with Diabetes Is Mediated by Physical Activity and BMI but Not Diet Quality

Loneliness is considered a predictor of poor health through numerous pathways. Mediators of this association has not been extensively explored. The study objective was to determine if diet quality and physical activity are parallel mediators with body mass index (BMI) as the third mediator in the association of loneliness with diabetes. The sample, middle-aged and older African American and White adults, 36-77 years, participated in the second follow-up wave of the prospective Healthy Aging in Neighborhoods of Diversity across the Life Span study, 2013-2017. Loneliness was measured by the UCLA 3-item loneliness scale. Participants were categorized as not diabetic, pre-diabetic, or diabetic based on fasting blood glucose, self-reports, or taking medication for diabetes. The Mean Healthy Eating Index-2010 score was calculated from two 24 h dietary recalls collected using the USDA automated multiple pass method. Physical activity was derived from the Baecke questionnaire. The Hayes PROCESS macro, model #80, was used to perform the mediational analysis. Covariates were age, sex at birth, race, income, alcohol intake, and education. Loneliness was inversely and significantly associated with diet quality and physical activity. The only significant indirect path was loneliness > physical activity > BMI > diabetes. Better understanding of modifiable lifestyle behaviors when developing interventions may improve mental health, thereby improving health.

The relationship between weight self-stigma, depression and loneliness in people with obesity

The research was conducted to determine the level of weight self-stigma, depression loneliness and whether is there a relationship between them. This was a descriptive correlational study. The study was conducted in a diet outpatient clinic of a university hospital. Participants had moderate weight self-stigma, depression and loneliness. Weight self-stigma sub-dimensions self-devaluation (β=0.28; p<0.001) and fear of enacted stigma (β=0.28; p<0.001) equally predicted depression. Fear of enacted stigma predicted social loneliness negatively (β=-.44; p<0.001). Fear of enacted stigma (β =.16, p<.005) and depression (β =.44, p<.001) predicted emotional loneliness positively. Weight self-stigma was positively correlated with depression and loneliness (p<0.001).

Mature Adults at the GP: Length of Visit and Patient Satisfaction—Associations with Patient, Doctor, and Facility Characteristics

Background and objectives: The consultation time for more mature adults is often perceived as longer, increasing with the patient’s age and boosting their satisfaction with the visit. However, factors determining patient satisfaction (PS) or the consultation time (CT) in the population aged 50+ are not clearly identified. A cross-sectional design was used to identify factors specific to the facility (e.g., size, staff turnover), doctor (e.g., seniority, workload), and patient (e.g., self-rated health, impairment of activities) that are related to PS and the CT. Our secondary focus was on the relation of PS to the CT along with the role of the patient’s age and gender for both. Materials and Methods: Doctors (n = 178) and their 1708 patients (aged 50–97) from 77 primary care facilities participated in the study. The Patient Satisfaction with Visit Scale score and the CT were the outcome measures. Results: We identified associations with the CT in terms of the facility-related factors (number of GPs, time scheduling); doctors’ workload and health; and patients’ education, time attending GP, and impairments. PS was additionally governed by doctors’ perceived rate of patients aged 65+, as well as the patients’ hospitalization in the prior year, frequency of visits, and impairments. For adults aged 50+ the CT was unrelated to PS and both remained independent of patients’ age. Conclusions: Specific factors in terms of the facility, GP, and patient were identified as related to PS and the CT for participating adults in primary care. During visits of patients aged 50+ at their GP, there is scope for both time-savings and patient satisfaction improvements, when paying attention, e.g., to the time scheduled per visit, the number of doctors employed, and the patients’ impairments.
