Factors important for health-related quality of life in men and women: The population based SCAPIS study

INTRODUCTION

Health-related quality of life (HRQoL) is essential for human wellbeing, influenced by a complex interplay of factors, and is reported lower in women than men. We aimed to evaluate which factors were the most important for HRQoL in a middle-aged general population.

METHODS

This was a cross-sectional, multi-centre study of 29,212 men (48%) and women (52%) aged 50-64 in the general population in Sweden. Physical and mental HRQoL (0-100) was assessed using the Short Form 12 questionnaire, and association was evaluated for 356 variables including demographics, lifestyle, symptoms, physiological measurements, and health conditions. Using machine learning, each variable´s importance for HRQoL was measured by an importance score, comparable to effect size, and summarised in 54 factors, in men and women separately.

RESULTS

Men and women had similar mean and standard deviation (SD) scores for physical HRQoL (53.4 [SD 8.1] vs 51.4 [9.7]) and mental HRQoL (37.1 [5.0] vs 37.3 [5.4]). The most important factors for physical HRQoL were (importance score) physical activity (40), employment (36), pain (33), sleep (33), and sense of control (26). The most important factors for mental HRQoL were sense of control (18), physical activity (12), depression (12), pain (6), and employment (5).

CONCLUSIONS

The factors important for HRQoL identified by this study are likely to be amenable to interventions, and our findings can support prioritising interventions. The identified factors need to be a target even before middle-age to lay the foundation for long and happy lives.

Socioeconomic status and self-rated health in Iran: findings from a general population study

Background

There are large gaps in health and well-being among different groups of the society. Socioeconomic factors play a significant role in determining the health status of the society. The present study was conducted to examine socioeconomic inequality in health status among the adult population of Khorramabad city, the capital of Lorestan province, wester part of Iran.

Methods

A cross-sectional study was conducted on 1348 participants selected through multistage sampling. A valid and reliable questionnaire was used for data collection. The wealth index as an indicator of the socioeconomic status (SES) was used to categorize the subjects in terms of the SES. The concentration index and concentration curve was used to measure socioeconomic inequity in poor self-rated health (SRH) of population. Finally, after determine the status of inequity in poor SRH, a decomposition analysis approach was used to identify the most important determinants of this inequity.

Results

The prevalence of poor SRH was 18.91% in all subjects, 38.52% in the lowest SES group, and 11.15% in the highest SES group. The value of the concentration index for poor SRH was − 0.3243 (95% CI − 0.3996 to − 0.2490), indicating that poor SRH was more concentrated among the poor. The results of decomposition analysis showed that SES (41.2%), higher body mass index (28.6%) and lack of physical activity (26.9%) were the most important factors associated with the concentration of poor SRH in the poor groups.

Conclusion

Identification of socioeconomic factors affecting on health status is the first step for proper policymaking. Policymakers and health system managers at the national and subnational levels can use the results of this study as well as other similar domestic studies to design and implement proper interventions to promote equity and improve the health status of population.

Self-rated health in relation to fruit and vegetable consumption and physical activity among older cancer survivors

PURPOSE

We aimed to investigate associations of self-rated health with fruit and vegetable consumption (FVC) and physical activity (PA) among older cancer survivors.

METHODS

We used the 2017 Behavioral Risk Factor Surveillance System to identify cancer survivors ≥ 65 years (N = 2663). Self-reported FVC and PA were categorized as ordinal variables to approximate quartiles. Low general health (LGH) was defined as fair or poor self-rated health. A multivariable logistic regression treating LGH as the outcome was used to calculate adjusted odd ratios (aORs) and 95% confidence intervals (CIs) for FVC and PA. Restricted cubic spline depicted non-linear dose-response curves for FVC and PA. In comparative analysis, we used the same logistic regression and dose-response model to calculate ORs of FVC and PA in 73,134 people ≥ 65 years without cancer history.

RESULTS

Overall, 470 (17.7%) survivors had LGH. Survivors' mean age was 73.3 years (SD = 5.2), 55.1% of them were female, and 95.4% self-reported as white. In cancer survivors, FVC was not associated with LGH (≥ 28 vs. < 14 times/week: aOR = 1.02, 95% CI = 0.75-1.39, p-trend = 0.50), whereas PA was inversely associated with LGH (≥ 30 vs. < 7 MET-hours/week: aOR = 0.55, 95% CI = 0.41-0.75, p-trend < 0.01). Dose-response curves demonstrated consistent association patterns. In comparative analysis, ORs of PA did not change substantially but we observed inverse association for FVC.

CONCLUSIONS

An inverse association between PA and LGH was observed among older cancer survivors, but no significant association was obtained for FVC among them. Regular PA may maintain or indicate a favorable health in older cancer survivors, whereas impacts of FVC deserve further investigations.

Postoperative Complications and Health-related Quality of Life 10 Years After Esophageal Cancer Surgery

OBJECTIVE

To evaluate the impact of postoperative complications on health-related quality of life (HRQOL) up to 10 years after surgery for esophageal cancer.

BACKGROUND

The impact of postoperative complications on HRQOL past 5 years is unknown.

METHODS

Some 616 patients undergoing open esophageal cancer surgery between April 2, 2001 and December 31, 2005 in Sweden were enrolled in this population-based, nationwide, and prospective cohort study. Exposure was the occurrence of predefined postoperative complications, and the outcome was HRQOL evaluated by validated European Organization for Research and Treatment of Cancer questionnaires at 6 months, 3, 5, and 10 years after surgery. Linear mixed models, adjusted for longitudinal HRQOL in the general population and confounders, provided mean score differences (MDs) with 95% confidence intervals (CIs) for each HRQOL item and scale in patients with or without postoperative complications.

RESULTS

At 10 years, 104 (17%) patients were alive and 92 (88%) answered the HRQOL questionnaires. Of these, 37 (40%) had at least 1 predefined postoperative complication. Twelve of the 25 scales and items were significantly worse in patients with postoperative complications 10 years after surgery, for example, physical function (MD -15, 95% CI -24 to -7), fatigue (MD 16, 95% CI 5-26), pain (MD 18, 95% CI 7-30), dyspnea (MD 15, 95% CI 2-27), insomnia (MD 20, 95% CI 8-32), and eating problems (MD 14, 95% CI 3-24) compared to patients without complications.

CONCLUSIONS

Postoperative complications are associated with considerably impaired HRQOL up to 10 years after esophageal cancer surgery.

Inequalities in health-related quality of life and the contribution from socioeconomic status: evidence from Tibet, China

Background

This study aimed to understand the association between socioeconomic status (SES) and Health Related Quality of Life (HRQoL) and the contribution of SES to health inequality among Tibetans of agricultural and pastoral areas (APA) in Tibet, China.

Methods

The data were from Health Survey of Tibetans in APA conducted in 2014. A total of 816 respondents were enrolled for the analysis Multiple linear regression was employed to examine the relationship between SES and HRQoL. Concentration index (CI) was used to measure the degree of health inequality and a Wagstaff-type CI decomposition method was applied to measure the contribution of SES to inequality.

Results

SES had significant association with HRQoL among the Tibetans in APA. The high SES group was more likely to have a higher Eq-5d index (0.77 vs. 0.67, P < 0.001) and VAS (72.94 vs. 62.41, P < 0.001) than the low SES group. The Concentration index of the Eq-5d index and VAS for total sample was 0.022 and 0.026 respectively, indicating a slight pro-rich inequality among this population. The decomposition analyses showed the SES is the main contributor to health inequality and contributed 45.50 and 41.39% to inequality for the Eq-5d index and VAS, respectively.

Conclusion

The results showed SES is positively associated with HRQoL among Tibetans in APA. There was a slight pro-rich inequality in the health of the participants and most health inequality was attributable to SES. This study is helpful in gaining an insight into the HRQoL, health inequality and the relationship between SES and health inequality among Tibetans of APA in China.

What Explains Socioeconomic Inequality in Health-related Quality of Life in Iran? A Blinder-Oaxaca Decomposition

OBJECTIVES

This study aimed to explain the health-related quality of life (HRQoL) gap between the poorest and the wealthiest quintiles in the capitals of Kermanshah and Kurdistan Provinces (Kermanshah and Sanandaj), in western Iran.

METHODS

This was a cross-sectional study conducted among 1772 adults. Data on socio-demographic characteristics, socioeconomic status (SES), lifestyle factors, body mass index, and HRQoL of participants were collected using a self-administered questionnaire. The slope and relative indices of inequality (SII and RII, respectively) were employed to examine socioeconomic inequality in poor HRQoL. Blinder-Oaxaca (BO) decomposition was used to quantify the contribution of explanatory variables to the gap in the prevalence of poor HRQoL between the wealthiest and the poorest groups.

RESULTS

The overall crude and age-adjusted prevalence of poor HRQoL among adults was 32.0 and 41.8%, respectively. The SII and RII indicated that poor HRQoL was mainly concentrated among individuals with lower SES. The absolute difference (%) in the prevalence of poor HRQoL between the highest and lowest SES groups was 28.4. The BO results indicated that 49.9% of the difference was explained by different distributions of age, smoking behavior, physical inactivity, chronic health conditions, and obesity between the highest and lowest SES groups, while the remaining half of the gap was explained by the response effect.

CONCLUSIONS

We observed a pro-rich distribution of poor HRQoL among adults in the capitals of Kermanshah and Kurdistan Provinces. Policies and strategies aimed at preventing and reducing smoking, physical inactivity, chronic health conditions, and obesity among the poor may reduce the gap in poor HRQoL between the highest and lowest SES groups in Iran.

Educational nurse-led lifestyle intervention for persons with mental illness

Although persons with severe mental illness face an increased risk of mortality and of developing negative health outcomes, research has shown that lifestyle interventions can sufficiently support their health. In response, this study examined a nurse-led lifestyle intervention developed in cooperation with members of municipal and county councils to gauge its impact on the quality of life, cognitive performance, walking capacity, and body composition of persons with severe mental illness. Lasting 26 weeks and involving 38 persons with severe mental illness, the intervention prioritised two components: the interpersonal relationships of persons with severe mental illness, staff, and group leaders and group education about physical and mental health. Pre-post intervention measurements of quality of life collected with the Manchester Short Assessment of Quality of Life, cognitive performance with the Frontal Systems Behaviour Scale, walking capacity with a 6-min walk test, and body composition in terms of waist circumference and body mass index were analysed using a nonparametric test Wilcoxon signed-rank test. Results suggest that the intervention afforded significant improvements in the health-related variables of quality of life, cognitive performance, walking capacity, and waist circumference for persons with severe mental illness. However, long-term studies with control groups and that examine parameters related to cardiovascular risk factors are essential to ensure the sustained impact of the intervention.

Impact of weight loss and eating difficulties on health-related quality of life up to 10 years after oesophagectomy for cancer

Background

Severe weight loss is experienced by patients with eating difficulties after surgery for oesophageal cancer. The aim of this prospective cohort study was to asssess the influence of eating difficulties and severe weight loss on health-related quality of life (HRQoL) up to 10 years after oesophagectomy.

Methods

Data on bodyweight and HRQoL were collected at 6 months, 3, 5 and 10 years in patients who underwent surgery for oesophageal cancer in Sweden between 2001 and 2005. Exposures were percentage weight loss, and eating difficulties defined by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-OES18 questionnaire. Outcomes were HRQoL scores from the EORTC QLQ-C30 questionnaire. Repeated-measures ANOVA, adjusting for potential confounders, was used to assess the association between eating difficulties and weight loss (4 exposure groups) and HRQoL scores at each time point. Mean score differences (MDs) between time points or exposure groups were defined as clinically relevant in accordance with evidence-based interpretation guidelines.

Results

In total, 92 of 104 10-year survivors (88·5 per cent) responded to the questionnaires. Weight loss was greatest within 6 months of surgery. Patients with eating difficulties with or without weight loss reported clinically and statistically significantly worsened HRQoL in almost all aspects. The largest MD was seen between 5 and 10 years after surgery for global quality of life, physical, role and social function (MD –22 to –30), as well for fatigue, nausea, dyspnoea, insomnia, appetite loss and diarrhoea (MD 24–36).

Conclusion

Eating difficulties are associated with deterioration in several aspects of HRQoL up to 10 years after surgery for oesophageal cancer.

Determinants of outcome of vocational rehabilitation

BACKGROUND

Information regarding the determinants of successful vocational rehabilitation (VR) is scarce.

OBJECTIVE

Investigate whether sex, duration, quality of life and financial circumstances influence the success of VR.

METHODS

The study group consisted of 519 participants (293 women, 56%), who finished VR in the period 2000-2014. The group was divided into the following subgroups: dropouts, unsuccessful and successful VR. Data were collected by questionnaire.

RESULTS

Income had the most impact on whether the outcome was successful. Having supplemental income when entering the VR program increased the likelihood of a successful conclusion, odds ratio (OR) 5.60 (95% CI; 2.43-13.59) (p < 0.001), being on sick leave OR 5.02 (95% CI 1.93-13.79) (p < 0.001) or rehabilitation pension OR 1.93 (95% CI 1.07-3.52) (p < 0.03). The participants in the successful sub-group were older (p < 0.06) and stayed in rehabilitation longer (p < 0.001), compared to those who were unsuccessful. However, the effect on OR was limited: 1.03 (95% CI 1.01-1.06) and 1.04 (95% CI 1.02-1.07), respectively.

CONCLUSIONS

For this sample, supplemental income appears to be the most important factor for a successful rehabilitation outcome. Checking financial status at the beginning of the rehabilitation process could minimize financial strain and increase the likelihood of success.

The physiological, musculoskeletal and psychological effects of stand up paddle boarding

Background

Stand up paddle boarding (SUP) is a rapidly growing sport and recreational activity where anecdotal evidence exists for its proposed health, fitness and injury rehabilitation benefits. While limited scientific evidence exists to substantiate these claims, previous studies have shown that high levels of fitness, strength and balance exists amongst participants of this sport. The purpose of this study was to conduct a training intervention on a group of previously untrained individuals to ascertain the potential of SUP on various health parameters.

Methods

An intervention study was conducted where after being tested initially, subjects were left for 6 weeks to act as their own control before the SUP intervention began. A total of 13 SUP participants completed the training study (nine males, four females) which was comprised of three 1 h sessions per week for 6 weeks.

Results

No significant changes occurred during the initial control period. Significant (P < 0.05) improvements were made in aerobic (+23.57 %) and anaerobic fitness (+41.98 %), multidirectional core strength tests (prone +19.78 %, right side +26.19 %, left side +28.31 %, Biering Sorensen +21.33 %) and self-rated quality of life questionnaires in the physical (+19.99 %) and psychological (+17.49 %) domains. No significant changes were detected in static or dynamic balance over the duration of the training intervention.

Conclusion

These results demonstrate the cardiovascular, musculoskeletal and psychological improvements achievable for the novice when utilizing SUP as a training tool. The result from this study provides some evidence to substantiate the claims of health and fitness benefits SUP.

Adverse lifestyle and health-related quality of life: gender differences in patients with and without chronic conditions

OBJECTIVES

The aim was to investigate the relationship between the main lifestyle-related factors and health-related quality of life (HRQoL) in a sample of patients with and without chronic conditions (CCs) with respect to the gender differences in both groups.

METHODS

A cross-sectional study was conducted on 1061 patients (of which 308 had no CCs and 753 of those had one or more CCs) recruited at primary health care centres and the Internal Medicine Clinic at Tartu University Hospital in Estonia. Data were collected during 2012-2014. The patient's age, self-reported smoking status, alcohol consumption (assessed by Alcohol Use Disorders Identification Test) and body mass index were used as independent variables to predict the physical component scores (PCS) and mental component scores (MCS) of HRQoL (assessed by SF-36).

RESULTS

Smoking had a negative association with both physical and mental components of HRQoL only in women with CCs. Further, the PCS of chronically ill women was negatively associated with the higher body mass index. Harmful drinking had a negative association with the HRQoL in all patient groups, except with the PCS in women with CC. Light alcohol consumption without symptoms of harmful use or dependency had a positive association with the physical and mental HRQoL in all patient groups, except with the MCS in women without CCs.

CONCLUSION

Adverse lifestyle had the most expressed association with HRQoL in women with CCs. Light alcohol consumption had a positive association, but harmful use of alcohol had an inverse association with HRQoL irrespective of patients' gender or health status.

Determinants of long-term quality of life in patients with differentiated thyroid carcinoma - a population-based cohort study in Sweden

BACKGROUND

Although differentiated thyroid cancer (DTC) has an excellent prognosis and a low incidence of recurrence, lifelong follow-up and medication might be needed. The aim of this study was to clarify how living with a cancer diagnosis for many years affects health-related quality of life (HRQoL) in DTC patients in Sweden.

MATERIAL AND METHODS

From the national all-encompassing population-based Swedish Cancer Registry, 353 patients diagnosed with DTC between 1995 and 1998 were identified and invited to answer the HRQoL questionnaire SF-36 and a study-specific questionnaire, 14-17 years after their diagnosis. Data were compared with a reference population as well between subgroups of patients.

RESULTS

Of the patients with DTC, 279 (79%) answered the questionnaires. In all, only 19 (7%) reported a recurrence, however, as many as 134 (48%) stated that they still had concerns about having a recurrence. The HRQoL in those with a recurrence was significantly lower than those without concerns of a recurrence in five of eight domains (p < 0.001-0.049). Similarly, patients with concerns of a recurrence reported poorer HRQoL than those without concerns, with significantly lower values in five domains (p < 0.001-0.008). Those few who stated that their disease had given them a negative view on life reported poor HRQoL in all eight domains (p < 0.001-0.030).

CONCLUSIONS

Even if DTC comes with an excellent prognosis, almost half of the patients, fully 15 years after diagnosis, worried about a recurrence which negatively impacted their HRQoL. Awareness among healthcare practitioners might improve information, supportive care and, in the end, the patient's HRQoL.
