Evaluation of bone mineral density and 25-hydroxyvitamin D levels in subjects with silica exposure

Objective

The purpose of the study was to evaluate the bone mineral density (BMD) and 25-hydroxyvitamin D (25(OH)D) levels in patients with silica exposure.

Materials and methods

The study included 104 male subjects with silica exposure and 36 healthy subjects. Posterior–anterior radiographs were classified according to the International Labour Office (ILO) Classification. Category 0 patients were classified as Group I (n = 54), category I patients were classified as Group II (n = 25), Category II and III patients were classified as Group III (n = 25).

Results

Femoral neck BMD values were significantly lower in Group III (p = 0.007). Lumbar vertebrae BMD values were significantly lower in all groups with silica exposure than in the control group (p = 0.000). The osteoporosis rate was significantly higher in Group III (p = 0.000). Subjects with silica exposure were determined to have diminished 25(OH)D levels (p = 0.012).

Conclusion

The results of this study demonstrated that subjects with silica exposure have diminished BMD and 25(OH)D levels.

     

Sustained quality of life improvement after intracoronary injection of autologous bone marrow cells in the setting of acute myocardial infarction: results from the BONAMI trial

Purpose

Cardiac cell therapy is a promising treatment for acute myocardial infarction (AMI), leading to cardiac function improvement. However, whether it translates into quality of life (QoL) improvement is unclear. We hypothesized that administration of bone marrow cells (BMC) to patients with AMI improves QoL.

Methods

In the multicenter BONAMI trial (NCT00200707), patients with reperfused AMI and decreased myocardial viability were randomized to intracoronary autologous BMC infusion (n = 52) or state-of-the-art therapy (n = 49). QoL data, derived from the Minnesota Living with Heart Failure questionnaire (MLHFQ), were obtained 1, 3, and 12 months after AMI and analyzed using a Rasch-family model.

Results

Using this model, QoL improved over time in the BMC group (p = 0.025) but not in the control group. Furthermore, the BMC-group patients displayed a better QoL than the control-group patients at 3 and 12 months post-AMI (p = 0.034 and p = 0.003, respectively). These findings were not detected when analyzing MLHFQ data using a standard method. Cardiac function, myocardial viability, mortality, and number of major adverse cardiac events did not differ between treatment groups.

Conclusion

Our results suggest that BMC therapy can improve QoL, stressing the need for confirmation trials and for systematic QoL assessment in cardiac cell therapy trials .

     

Using Electronic Health Record Alerts to Increase Safety Planning with Youth At-Risk for Suicide: A Non-randomized Trial

Background

No study to date has examined the effectiveness of integrating clinical decision support tools, like electronic health record (EHR) alerts, into the clinical care of youth at-risk for suicide.

Objective

This study aimed to examine the feasibility and acceptability of using an EHR alert to increase clinicians’ use of safety planning with youth at-risk for suicide in an outpatient pediatric psychiatry clinic serving an urban low-income Latino community.

Methods

An alert intervention was developed to remind clinicians to complete a safety plan whenever they documented that their patient endorsed suicidal ideation, plan, or attempt during a visit in EHR notes. The alert appeared as a separate window containing a reminder message to complete a safety plan once a clinician finished visit documentation.

Results

There were 69 at-risk patients between the ages of 13–21 in the intervention period (M = 15.71; SD = 1.86; 66.7% female) and 64 (M = 15.38; SD = 1.93; 68.6% female) in the control period. Logistic regression analyses indicated that patients in the intervention period were significantly more likely than patients in the control period to receive a safety plan (p < .01). The pattern of results remained the same after adjusting for demographic variables (p = .01). Forty clinicians also completed a questionnaire assessing their satisfaction with the EHR alert, indicating moderate satisfaction (M = 3.01; SD = 0.63; range = 1.11–4.11).

Conclusions

EHR alerts are associated with changes in clinicians’ behavior and improved compliance with best clinical practices for at-risk youth.

     

Is It Safe? Reliability and Validity of Structured Versus Unstructured Child Safety Judgments

Background

The LIRIK, an instrument for the assessment of child safety and risk, is designed to improve assessments by guiding professionals through a structured evaluation of relevant signs, risk factors, and protective factors.

Objective

We aimed to assess the interrater agreement and the predictive validity of professionals’ judgments made with the LIRIK in comparison to unstructured judgments.

Method

In study 1, professionals made safety and risk judgments for 12 vignettes with the LIRIK (group 1, n = 36) or without an instrument (group 2, n = 43). In study 2, we compared professionals’ safety and risk judgments for 370 children made with the LIRIK (group 1, n = 278) or with no instrument (group 2, n = 92), with outcomes indicating actual unsafety in files 6 months later.

Results

In study 1, agreement about safety and risks was poor to moderate in both groups. Differences between groups were small and inconsistent. In study 2, the predictive validity of judgments was weak to moderate in both groups. In neither group had unsafe outcomes increased consistently when unsafety or risks were assessed as higher.

Conclusions

Judgments made with the LIRIK were not more reliable or valid than unstructured professional judgments. These findings raise important questions about the value of risk assessment instruments and about how professional safety and risk judgments can be improved.

     

Efficacy and safety of fermented garlic extract on hepatic function in adults with elevated serum gamma-glutamyl transpeptidase levels: a double-blind,randomized, placebo-controlled trial

Purpose

Alcoholic liver disease or non-alcoholic fatty liver disease/non-alcoholic steatohepatitis are well-known risk factors for liver fibrosis or cirrhosis and hepatocellular carcinoma; it is a major global health concern, but there are few effective and safe management options. Therefore, we aimed to investigate the effects of fermented garlic extracts (FGEs) on hepatic function in adults with mild hepatic dysfunction without underlying hepatic disease.

Methods

In this double-blind, randomized, placebo-controlled study, seventy-five adults with elevated serum gamma-glutamyl transpeptidase (GGT) levels were included in a FGE-administered group (n = 36) or a placebo group (n = 39), and received either two sachets/day containing FGEs or placebo over a 12-week period. Primary endpoint was the change in serum GGT levels. Data were analysed using a generalized linear mixed effects model.

Results

Significant group × time interactions for serum levels of GGT (F = 3.98, P = 0.022) and alanine aminotransferase (ALT; F = 3.28, P = 0.043) were observed with an improvement in levels of GGT (P = 0.066) and ALT (P = 0.014) in the FGE group compared to that reported for the placebo group at the 12-week visits. There was no intergroup difference in the prevalence of adverse events.

Conclusions

Intake of FGEs improved serum GGT and ALT levels in adults with mildly elevated serum GGT level without reported adverse side effects. FGEs might be effective and safe management options for mild hepatic dysfunction.

     

Testing the measurement invariance of the University of Washington Self-Efficacy Scale short form across four diagnostic subgroups

Purpose

The University of Washington Self-Efficacy Scale (UW-SES) was originally developed for people with multiple sclerosis (MS) and spinal cord injury (SCI). This study evaluates the measurement invariance of the 6-item short form of the UW-SES across four disability subgroups. Evidence of measurement invariance would extend the UW-SES for use in two additional diagnostic groups: muscular dystrophy (MD) and post-polio syndrome (PPS).

Methods

Multi-group confirmatory factor analysis was used to evaluate successive levels of measurement invariance of the 6-item short form, the UW-SES: (a) configural invariance, i.e., equivalent item-factor structures between groups; (b) metric invariance, i.e., equivalent unstandardized factor loadings between groups; and (c) scalar invariance, i.e., equivalent item intercepts between groups. Responses from the four groups with different diagnostic disorders were compared: MD (n = 172), MS (n = 868), PPS (n = 225), and SCI (n = 242).

Results

The results of this study support that the most rigorous form of invariance (i.e., scalar) holds for the 6-item short form of the UW-SES across the four diagnostic subgroups.

Conclusions

The current study suggests that the 6-item short form of the UW-SES has the same meaning across the four diagnostic subgroups. Thus, the 6-item short form is validated for people with MD, MS, PPS, and SCI.

     

Different healthy habits between northern and southern Spanish school children

Aim

Healthy habits are influenced by several factors such as geographical location. The aims of this study were to describe and compare healthy habits within two populations of sixth-grade primary school children (aged 11–12 years) from northern and southern Spain.

Subjects and methods

A cross-sectional study using two representative samples of school children was conducted. Participants came from Logroño (n = 329) in the north and Granada (n = 284) in the south of Spain. Socio-demographic and anthropometric variables, adherence to the Mediterranean diet, aerobic fitness, and healthy lifestyles were recorded.

Results

Boys reported a higher level of physical activity and aerobic fitness than girls (p = 0.000). Southern school children reported significantly higher adherence to the Mediterranean diet (♀: p = 0.041; ♂: p = 0.008), lower aerobic fitness (♀: p = 0.000; ♂: p = 0.042) and hours of nightly sleep (♀: p = 0.008, ♂: p = 0.007) than northern school children. Southern boys also reported lower levels of physical activity (p = 0.013). There were slight or moderate correlations among all habits measured (physical activity, diet, screen and sleep time). Additionally, the physical activity level was inversely related to weight status. Overweight and obese northern boys reported less physical activity than healthy-weight northern boys (p = 0.020) and overweight and obese southern girls reported less physical activity than healthy-weight southern girls (p = 0.024).

Conclusions

Results showed differences in physical activity, eating and sleep habits, and aerobic fitness according to geographical location. The relationships found among lifestyle habits indicate the need for health promotion interventions nationally and considering the differences discussed here.

     

When global rating of change contradicts observed change: Examining appraisal processes underlying paradoxical responses over time

Aims

Interpreting change scores is challenging when patients’ global rating of change (GRC) scores contradict their observed change scores. We examine appraisal processes associated with having GRC-observed change contradictions.

Methods

This secondary analysis of longitudinal multiple sclerosis (MS) registry data examined predictors of GRC scores in the whole sample (n = 858). Logistic modeling then examined predictors of membership in one of two paradoxical subgroups (n = 525): (a) Worsened GRC with unchanged observed Rand-12 Mental Component scores (MCS) (Symptom-Maximizers, n = 171) versus no change GRC among stable MCS subsample; and (b) same GRC with declined observed MCS scores (Symptom-Minimizers, n = 84) versus declining GRC among declining MCS subsample. Independent variables were cognitive appraisal processes from the Quality of Life (QOL) Appraisal Profile.

Results

GRC scores were more strongly associated with appraisal processes than with change in patient-reported outcomes (PROs) (R ² = 11 and 2 %, respectively). Symptom-Maximizers tended to focus on MS-related experiences and emphasize big changes; over time, they decreasingly defined QOL in terms of independence, increasingly focused on their MS, and increasingly compared themselves to doctor’s predictions (Pseudo R ² = 0.20). In contrast, Symptom-Minimizers tended not to recall recent episodes; over time, they focused increasingly on goals related to living situation and emphasized long-term concerns (Pseudo R ² = 0.25).

Conclusions

Appraisal explains more variance in GRC scores than do changes in PROs. People whose GRC assessment contradicts their observed change can be characterized by distinct cognitive appraisal processes reflecting response shift.

     

The impact of taste and smell alterations on quality of life in head and neck cancer patients

Purpose

Taste and smell alterations (TSAs) are among the most frequent and troublesome symptoms reported by head and neck cancer (HNC) patients after treatment. Little is known about the relationship between TSAs and quality of life (QoL) among HNC patients. The aim of this study was to determine the effect of TSAs on overall QoL among tube-fed and orally fed HNC patients before treatment, at end of treatment and at 2.5-month follow-up.

Methods

Data were collected in a longitudinal study prior to treatment (n = 126), at end of treatment (n = 100) and at 2.5-month follow-up (n = 85). Chemosensory Complaint Score (CCS) and the University of Washington Quality of Life Questionnaire version 3 were used to assess TSAs and QoL, respectively. Generalized estimated equation modeling was used to estimate the effect of CCS on QoL.

Results

At end of treatment, QoL and CCS had declined for both tube-fed and orally fed patients and thereafter improved, but not to pre-treatment levels. Neither QoL nor CCS mean scores were different between the two groups at any time point. CCS was a significant predictor of overall QoL (β = ?1.82, p < 0.0001), social-emotional (β = ?1.76, p < 0.0001), physical (β = ?1.12, p < 0.0001) and overall functions (β = ?1.15, p < 0.0001) at a multivariate level. Taste was reported as an important symptom for both tube-fed and orally fed groups at end of treatment and follow-up.

Conclusions

TSAs are an important symptom and an independent predictor of QoL for both tube-fed and orally fed HNC patients. HNC patients need support to manage TSAs, regardless of the method of nutritional intake.

     

Correlation of emotional labor and cortisol concentration in hair among female kindergarten teachers

Objectives

The purpose of this study was to explore whether two types of emotional labor, surface acting and deep acting, are related to hair cortisol concentration among kindergarten teachers.

Methods

Surface acting and deep acting over the last month were measured with the Chinese version of the emotional labor scale in 43 kindergarten teachers. Hair samples with 1 cm in length were cut from their posterior vertex region to represent cortisol excretion over one month. Cortisol concentrations were analyzed with high-performance liquid chromatography–tandem mass spectrometry.

Results

Positive association of emotion labor with hair cortisol concentration was significant for surface acting (r = 0.34, p < 0.05) and not significant for deep acting (r = 0.14, p > 0.05).

Conclusions

More surface acting showed to be associated stronger with stress responses or higher HPA axis activity.

     

EQ-5D in Central and Eastern Europe: 2000–2015

Objective

Cost per quality-adjusted life year data are required for reimbursement decisions in many Central and Eastern European (CEE) countries. EQ-5D is by far the most commonly used instrument to generate utility values in CEE. This study aims to systematically review the literature on EQ-5D from eight CEE countries.

Methods

An electronic database search was performed up to 1 July 2015 to identify original EQ-5D studies from the countries of interest. We analysed the use of EQ-5D with respect to clinical areas, methodological rigor, population norms and value sets.

Results

We identified 143 studies providing 152 country-specific results with a total sample size of 81,619: Austria (n = 11), Bulgaria (n = 6), Czech Republic (n = 18), Hungary (n = 47), Poland (n = 51), Romania (n = 2), Slovakia (n = 3) and Slovenia (n = 14). Cardiovascular (21 %), neurologic (17 %), musculoskeletal (15 %) and endocrine, nutritional and metabolic diseases (13 %) were the most frequently studied clinical areas. Overall, 112 (78 %) of the studies reported EQ VAS results and 86 (60 %) EQ-5D index scores, of which 27 (31 %) did not specify the applied tariff. Hungary, Poland and Slovenia have population norms. Poland and Slovenia also have a national value set.

Conclusions

Increasing use of EQ-5D is observed throughout CEE. The spread of health technology assessment activities in countries seems to be reflected in the number of EQ-5D studies. However, improvement in informed use and methodological quality of reporting is needed. In jurisdictions where no national value set is available, in order to ensure comparability we recommend to apply the most frequently used UK tariff. Regional collaboration between CEE countries should be strengthened.

     

The effects of the Make a Wish intervention on psychiatric symptoms and health-related quality of life of children with cancer: a randomised controlled trial

Objective

Children with life-threatening medical conditions frequently undergo invasive medical procedures that may elicit anxiety and distress. However, there are few empirically validated interventions that reduce mental health symptoms and increase the resilience of children during the acute stages of illness. This study aimed to evaluate the efficacy of the Make a Wish intervention for children with life-threatening cancer.

Methods

The design was a wait-list-controlled trial with two parallel groups. Sixty-six children aged 5–12 with an initial diagnosis of life-threatening cancer were identified and randomly assigned to the Make a Wish intervention (n = 32) or a wait-list control group (n = 34). Children completed measures of psychiatric and health-related symptoms, positive and negative affect, hope, and optimism pre-intervention and post-intervention. After baseline data collection, children were interviewed and made an authentic wish that they wanted to come true. These wishes were made possible 5–6 months after baseline data collection, to fuel anticipation and excitement over the wish-fulfillment event. The post-intervention assessment point was 5 weeks after wish fulfillment (approximately 7 months after baseline data collection).

Results

Children in the intervention group exhibited a significant reduction in general distress (d = 0.54), depression (d = 0.70), and anxiety symptoms (d = 0.41), improved health-related quality of life (d = 0.59), hope (d = 0.71), and positive affect (d = 0.80) compared to decrease in positive affect and no significant changes in the other measures in the control group.

Conclusions

These findings emphasize the role of hope and positive emotions in fostering the well-being of children who suffer from serious illnesses.

     

Minimal impact of response shift for SF-12 mental and physical health status in homeless and vulnerably housed individuals: an item-level multi-group analysis

Purpose

The purpose of this study was to examine whether homeless or vulnerably housed individuals experienced response shift over a 12-month time period in their self-reported physical and mental health status.

Methods

Data were obtained from the Health and Housing in Transition study, a longitudinal multi-site cohort study in Canada (N = 1190 at baseline). Multi-group confirmatory factor analysis (MG-CFA) and methods for response shift detection at the item level, based on the approach by Oort, were used to test for reconceptualization, reprioritization, and recalibration response shift on the SF-12 in four groups of individuals who were homeless (n = 170), housed (n = 437), or who reported a change in their housing status [from homeless to housed (n = 285) or housed to homeless (n = 73)] over a 12-month time period. Mean and variance adjusted weighted-least squares estimation was used to accommodate the ordinal and binary distributions of the SF-12 items.

Results

Using MG-CFA, a strict invariance model showed that the measurement model was equivalent for the four groups at baseline. Although we found small but statistically significant response shift for several measurement model parameters, the impact on the predicted average mental and physical health scores within each of the groups was small.

Conclusions

Response shift does not appear to be a significant concern when using the SF-12 to obtain change scores over a 12-month period in this population.

     

In support of an individualized approach to assessing quality of life: comparison between Patient Generated Index and standardized measures across four health conditions

Background

Individualized measures of health-related quality life (HRQL) have been used for decades and shown to provide unique information, but little work has been done to explain this uniqueness particularly across health conditions.

Aims

To estimate, across four health conditions, the magnitude of the association between scores derived from the Patient Generated Index (PGI) and those from fully standardized generic and disease-specific measures of the HRQL; to identify the extent to which the areas generated from the PGI are covered by the content of the fully standardized measures.

Methods

The PGI and other generic and disease-specific measures had been used in four different samples of people: stroke (n = 222), multiple sclerosis (MS; n = 185); advanced cancer (n = 173), and HIV+ (n = 690). Areas nominated on the PGI were harmonized to a standard nomenclature. Pearson correlations were estimated between PGI and other measures.

Results

Data from 1263 people indicated that PGI provided the lowest rating for HRQL across all health conditions. The areas nominated differed across conditions with walking/mobility: the most common for stroke (42%), work/school for MS (62%), health for HIV+ (97%), and fatigue for cancer (39%). Many of the aspects of health included in generic measures were not nominated using the PGI and vice versa. The highest correlations between the PGI and other measures were observed for people with MS, with correlations between 0.53 and 0.59; lowest correlations were observed for people with HIV and cancer, ≤0.33.

Discussion

The PGI scores reflect those aspects of quality of life that are important to patients in which they would most value an improvement. Heterogeneity in HRQL across health conditions is poorly discriminated using standardized measures. A “one-size-fits-all” approach to HRQL assessment may not provide the most useful representation of this important construct.

     

The benefits of sleep coaching in workplace health promotion

Aim

In the present study, the benefits of a short-term sleep coaching intervention embedded in the workplace health promotion (WHP) program of the German Armed Forces was investigated.

Participants and methods

Well-being, self-care awareness, self-care behavior and irritation of participants attending the sleep coaching (n = 24) and participants attending other courses offered in the WHP program (n = 24) were assessed before and after the intervention.

Results

Participants attending the sleep coaching had a significant increase in well-being, self-care behavior and self-care awareness and a significant decrease in their irritation score after attending the sleep coaching. In the control group, no significant change in the dependent variables was observed; furthermore, participants’ evaluation of the sleep coaching was positive on both affective reactions and utility judgements.

Conclusions

Results show that the sleep coaching intervention evaluated is practically feasible and able to improve important indicators of employees’ well-being and self-care in WHP programs.

     

Factors influencing the reinforcing value of fruit and unhealthy snacks

Objective

The present study investigated the reinforcing value of healthy and unhealthy snack food in adolescents (n = 108, aged 14–16 years). Moderation by access to different foods, sex and the personality trait reward sensitivity is tested.

Methods

In a computerized Food Reinforcement Task, adolescents could earn portions of a healthy and an unhealthy snack following an identical progressive reinforcement schedule for both food types. Reinforcing value of food was indexed by the number of button presses for each food type. Participants were allocated randomly to two-order condition: fruit–snack versus snack–fruit. Reward sensitivity was assessed with the Dutch age-downward version of Carver and White’s BIS/BAS scale.

Results

Results showed that the reinforcing value of an unhealthy snack is higher than that of fruit, with participants making more button presses for unhealthy snacks, M = 1280.40, SD = 1203.53, than for fruit, M = 488.04, SD = 401.45, F(1,48) = 25.37, p < 0.001. This effect is stronger in boys (β = ?1367.67) than in girls (β = ?548.61). The effect is only present in the snack–fruit condition, not in the fruit–snack condition, indicating that access to food moderates the effect of food type. There is no evidence for moderation by reward sensitivity.

Conclusions

Results point to the importance of simultaneously increasing barriers to obtain unhealthy food and promoting access to healthy food in order to facilitate healthy food choices.

     

Gender,race, BMI,and social support in relation to the health-related quality of life of cancer survivors: a report from the American Cancer Society’s Study of Cancer Survivors II (SCS-II)

Purpose

We examined the main and interactive effects of race, BMI, and social support on physical and mental health-related quality of life (HRQoL) among male and female cancer survivors using the stress and coping theory to inform findings.

Methods

HRQoL issues among 1768 cancer survivors were examined using the American Cancer Society’s cross-sectional Study of Cancer Survivors II. Two-step multiple linear regressions were conducted to assess the physical and mental HRQoL of male and female cancer survivors, respectively.

Results

The average age of participants was 67.36 (SD = 11.51); the majority were female (53.3 %; n = 941) and non-Hispanic White (85.9 %; n = 1517). The average BMI measurement for participants was 28.33 (SD = 5.90), with 41.3 % (n = 729) overweight and 30.3 % (n = 535) obese. Higher BMI was significantly associated with lower physical HRQoL across gender, while social support had significant main effects on physical and mental HRQoL across gender. Race moderated the relationship between social support and physical HRQoL among female cancer survivors and between BMI and mental HRQoL for both genders.

Conclusions

The results of this study contribute a unique gender- and racial-specific perspective to cancer survivorship research. While the buffering hypothesis of the stress and coping theory was not supported, the main effects of BMI and social support on HRQoL were different across gender and race.

     

Dietary iron intake and availability are related to maternal education level in overweight/obese adolescents

Purpose

To compare intakes of dietary iron and enhancers and inhibitors of iron absorption between overweight/obese (OW/OB) adolescents and their normal weight (NW) peers, and between parental education levels stratified by weight status.

Methods

This was a comparative cross-sectional study of adolescents (n 121 OW/OB and n 102 NW) aged 12–14 years, attending a secondary school in Nonthaburi province, Thailand. Socio-demographic data were obtained from participants’ parents using a questionnaire. Participants recorded their intakes for 3 non-consecutive days, using a prospective food record.

Results

Compared with NW adolescents, OW/OB adolescents consumed more total protein and animal protein after adjustment for energy intake (both p = 0.047). OW/OB adolescents whose mothers were less educated consumed more total iron and available iron after adjustment for energy intake, compared with their OW/OB peers whose mothers were more educated (p = 0.045 and p = 0.040). NW adolescents with more highly educated mothers had higher absolute and energy-adjusted fibre intakes (both p = 0.047). However, NW adolescents of mothers with a high–intermediate level of education consumed less calcium, after adjustment for energy intake (p = 0.028).

Conclusions

OW/OB adolescents with less educated mothers had higher energy-adjusted intakes of iron and available iron. Dietary differences in OW/OB adolescents relative to maternal education, and other socioeconomic indicators, should be explored in a nationally representative data set.

     

The association between social network factors and mental health at different life stages

Objectives

Psychosocial factors are important determinants of an individual’s health. This study examines the association between health scores and social network factors on mental health across different life stages.

Methods

Data were drawn from the Household Income and Labour Dynamics in Australia survey for adolescents (n = 1739), adults (n = 10,309) and seniors (n = 2287). Hierarchical regression modelling was applied to examine effects within and across age groups. All the variables were derived from the self-completion questionnaire.

Results

The social network factors were statistically significant predictors of mental health outcomes for all three life stages. For adolescents, the three social network factors were statistically significant with social isolation having the largest impact (β = ?.284, p < .001), followed by social connection (β = .084, p < .001) and social trust having a similar effect (β = .073, p < .001). For adults social isolation had the highest impact (β = ?.203, p < .001), followed by social connection (β = .110, p < .001) and social trust (β = .087, p < .001).The results for seniors were social isolation (β = ?.188, p < .001), social connection (β = .147, p < .001) and social trust (β = .032, p < .05).

Conclusions

After adding the social network factors, the models improved significantly with social isolation playing the most significant role across all life stages, whereas the other social network factors played a differentiated role depending upon the life stage. These findings have practical implications in the design of mental health interventions across different life stages.
