Abstract Objective: By comparing the psychometric properties of the Short Form 36 (version 1, SF-36) and the Short Form 12 (version 1, SF-12), we supply evidence for the selection of instruments measuring the quality of life (QOL) and decision-making processes of adolescents in China. Methods: Stratified cluster random sampling was adopted, and the SF-36 was administered to assess QOL. The Pearson correlation coefficient was used to show correlation. Cronbach’s alpha and construct reliability (CR) were used to evaluate the reliability of SF-36 and SF-12, while criterion validity and average variance extracted (AVE, convergence validity) were used to evaluate validity. Confirmatory factor analysis was used to calculate the load factor for each item, then to obtain the CR and AVE. The Semejima grade response model (logistic two-parameter module) in item response theory was used to estimate item discrimination, item difficulty, and item average information for each item. Results: 19,428 samples were included in the study. The mean age of respondents was 14.78 years (SD = 1.77). High correlations between the corresponding domains and components of both scales were found. Reliability of each domain of the SF-36 was better than for the corresponding domain of SF-12. The domains of PF, RP, BP, and GH in SF-36 had good construct reliability (CR > 0.6). The criterion validities of SF-36 were a little higher in some corresponding dimensions, except for PCS. The convergence validities of SF-12 were higher than SF-36 in PF, RP, BP, and PCS. The items of BP, SF, RP, and VT in SF-12 had acceptable discrimination of items that were higher than in SF-36. The items’ average amounts of information of BP, VT, SF, RE, and MH in SF-36 and SF-12 were poor. Conclusion: Two component measurements of the SF-12 (PCS and MCS) appeared to perform at least as well as the SF-36 in cross-sectional settings in adolescence, but the reliability and validity of 8 domains of the SF-36 were better than those of SF-12. Some domains, for instance SF and BP, were not suitable for adolescents or need no further study.

Abstract Objective We compare the reliability and validity of the Short Form 36 (version 1, SF-36) and the Short Form 12 (version 1, SF-12) in adolescence, the period of life when a child develops into an adult, i.e., the period from puberty to maturity terminating legally at the age of majority (10–19 years), thus supplying evidence for the selection of instruments measuring the quality of life (QOL) and decision-making processes of adolescents in China. Methods Stratified cluster random sampling was adopted according to geographical location, and the SF-36 was administered to assess QOL. The Pearson correlation coefficient was used to show correlation. Cronbach’s alpha and construct reliability (CR) were used to evaluate the reliability of SF-36 and SF-12, while criterion validity and average variance extracted (AVE, convergence validity) were used to evaluate validity. Confirmatory factor analysis was used to calculate the load factors for the items of the SF-36 and SF-12, then to obtain the CR and AVE.

CONTEXT AND OBJECTIVE: Quality of life (QoL) is considered important as an outcome measurement, especially for long-term diseases such as chronic renal failure. The present study searched for predictors of QoL in a sample of patients undergoing dialysis in southern Brazil. DESIGN AND SETTING: This was a cross-sectional study developed in three southern Brazilian dialysis facilities. METHODS: Health-related QoL of patients on hemodialysis or peritoneal dialysis was measured using the generic Short Form-36 (SF-36) health survey questionnaire. The results were correlated with sociodemographic, clinical and laboratory variables. The analysis was adjusted through multiple linear regression. RESULTS: A total of 140 patients were assessed: 94 on hemodialysis and 46 on peritoneal dialysis. The mean age was 54.2 ± 15.4 years, 48% were men and 76% were white. The predictors of higher (better) physical component summary in SF-36 were: younger age (β-0.16; 95% confidence interval, CI: -0.27 to -0.05), shorter time on dialysis (β-0.06; 95% CI: -0.09 to -0.02) and lower Khan comorbidity-age index (β 5.16; 95% CI: 1.7-8.6). The predictors of higher mental component summary were: being employed (β 8.4; 95% CI: 1.7-15.1), being married or having a marriage-like relationship (β 4.56; 95% CI: 0.9-8.2), being on peritoneal dialysis (β 4.9; 95% CI: 0.9-8.8) and not having high blood pressure (β 3.9; 95% CI: 0.3-7.6). CONCLUSIONS: Age, comorbidity and length of time on dialysis were the main predictors of physical QoL, whereas socioeconomic issues especially determined mental QoL.

Active Acromegaly

The value of measuring IGF1 bioactivity in active acromegaly is unknown. Soluble Klotho (S-Klotho) level is elevated in active acromegaly and it has been suggested that S-Klotho can inhibit activation of the IGF1 receptor (IGF1R). A cross-sectional study was carried out in 15 patients with active acromegaly based on clinical presentation, unsuppressed GH during an oral glucose tolerance test, and elevated total IGF1 levels (>+2 s.d.). Total IGF1 was measured by immunoassay, IGF1 bioactivity by the IGF1R kinase receptor activation assay and S-Klotho by an ELISA. Quality of Life (QoL) was assessed by Acromegaly QoL (AcroQoL) Questionnaire and Short-Form-36 Health Survey Questionnaire (SF-36). Out of 15 patients, nine had IGF1 bioactivity values within the reference range. S-Klotho was higher in active acromegaly compared with controls. Age-adjusted S-Klotho was significantly related to IGF1 bioactivity (r=0.75, P=0.002) and to total IGF1 (r=0.62, P=0.02). IGF1 bioactivity and total IGF1 were inversely related to the physical component summary of the SF-36 (r=−0.78, P=0.002 vs r=−0.60, P=0.03). Moreover, IGF1 bioactivity, but not total IGF1, was significantly inversely related to the physical dimension of the AcroQoL Questionnaire (r=−0.60, P=0.02 vs r=−0.37, P=0.19). In contrast to total IGF1, IGF1 bioactivity was within the reference range in a considerable number of subjects with active acromegaly. Elevated S-Klotho levels may have reduced IGF1 bioactivity. Moreover, IGF1 bioactivity was more strongly related to physical measures of QoL than total IGF1, suggesting that IGF1 bioactivity may better reflect physical limitations perceived in active acromegaly.

Introduction Mouth breathing can affect the functions of the respiratory systems and quality of life. For this reason, children who grow up with this stimulus may have implications on physical and psychological aspects at adult age.Objective To evaluate childhood mouth-breathing consequences for the ventilatory function and quality of life at adult age.Materials and methods Prospective, observational and cross-sectional study with 24 adults, between 18 and 30 years old, mouth breathers during childhood, comprised the childhood mouth-breathing group (CMB). The childhood nasal-breathing (CNB) group was composed of 20 adults of the same age, without history of respiratory disease during all their lives. Measurements of maximal respiratory pressures, peak expiratory flow and 6-minute walk test were assessed. In addition, all the volunteers answered the Short Form-36 questionnaire (SF-36).Results The maximal inspiratory (p = 0.001) and expiratory (p = 0.000) pressures as well as the distance in the walk test (p = 0.003) were lower in the COB. The COB also presented lower score in the General Health domain of the SF-36 Questionnaire (p = 0.002).Conclusion Childhood mouth-breathing yields consequences for the ventilatory function at adult age, with lower respiratory muscle strength and functional exercise capacity. Conversely, the quality of life was little affected by the mouth breathing in this study.

Abstract Background Urinary incontinence (UI) and low quality of life (QoL) are two common conditions. Some recent literature proposed that these two entities can be associated. However, no attempt was made to collate this literature. Therefore, the aim of this study was to conduct a systematic review and meta-analysis of existing data to estimate the strength of the association between UI and QoL. Methods An electronic search of major databases up to 18th April 2020 was carried out. Meta-analysis of cross-sectional and case–control studies comparing mean values in QoL between patients with UI and controls was performed, reporting random-effects standardized mean differences (SMDs) ± 95% confidence intervals (CIs) as the effect size. Heterogeneity was assessed with the I2. Results Out of 8279 articles initially screened, 23 were finally included for a total of 24,983 participants, mainly women. The mean age was ≥ 50 years in 12/23 studies. UI was significantly associated with poor QoL as assessed by the short-form 36 (SF-36) total score (n = 6 studies; UI: 473 vs. 2971 controls; SMD = − 0.89; 95% CI − 1.3 to − 0.42; I2 = 93.5) and by the sub-scales of SF-36 and 5/8 of the domains included in the SF-36. Similar results were found using other QoL tools. The risk of bias of the studies included was generally high. Conclusions UI is associated with a poor QoL, with a strong level of certainty. This work, however, mainly based on cross-sectional and case–control studies, highlights the necessity of future longitudinal studies for better understanding the importance of UI on QoL.

Background: With increase in prevalence of stroke and life expectancy the quality of life of stroke survivors assumes importance. Despite advances in diagnosis and treatment of cerebrovascular accidents the survivors continue to experience low Quality of life (QoL) especially in developing countries. The objective of this study was to assess the quality of life among stroke survivors and the prevalence of depression among them.  Methods: Cross-sectional population based study was conducted in a rural area of North Kerala. Stoke survivors were interviewed at home to assess the quality of life and depression status. QOL was assessed using the Medical Outcomes 36-Item Short-Form Health Survey (SF-36), functional status using the modified barthel index (MBI), and mood using the Beck’s Depression Inventory (BDI).Results: A total of 40 patients (65.5% men, mean age 70.58±10.7 years) were interviewed.  The mean MBI was 55.25±2.79, and the prevalence of unrecognized depression was 90%. 95 percent of patients needed varying degrees of care for their activities of daily living. The SF-36 scores of the patients were considerably lower than that to that of the general population especially in the areas of role limitation and physical functioning. Depression was more among older subjects and Depressed patients had lower MBI scoresConclusions: A significant proportion of stroke survivors continue to face limitations in their physical activities. In addition, majority have unrecognised depression that affects their QOL adversely.

Quality of life (HRQoL) is a measure of a person's health in physical, spiritual, and emotional, and role functions in the society. Measurement of quality of life (HRQoL) is an important thing to understand and evaluate. Measurements are carried out not only on patients but also on the general population with the use of specific or generic instruments. The instrument used requires a psychometric properties test to ensure its validity and reliability. This article aims to conduct a systematic review of the psychometric properties of quality of life (HRQoL) instruments in the general population. Articles were collected in December 1st to 5th, 2018, from Pubmed and Google Scholar. The assessment was carried out using the checklist properties according to the cohen criteria and included the content validity, construct validity, internal consistency reliability, test-retest, ceiling effect and the level of credibility of the instruments. Among 80 articles obtained there were 24 articles that fulfilled the inclusion criteria. Short Form-36 (SF-36) instrument is the most widely used instrument in measuring the quality of life in the general population (26.6%). Some instruments have not been tested according to the criteria, while almost all instruments show a good level of validation of construct validity using convergent and discriminat validity with cronbach alpha values > 0.7. Test-retest reliability provides a good correlation. Some instruments show a ceiling effect. According to the assessment, the SF-36, SF-6D, EQ-5D, SF-12 and PedsQoL instruments are considered as established instruments. Further validation testing is needed to provide and support the measurement of subsequent quality of life (HRQoL) instruments.

Different Levels

Rheumatoid arthritis (RA) is a systemic inflammatory autoimmune disease with impact on increasing the morbidity and mortality rates. Different levels of disease activity (LDA) have been established, however, its impact on pain and quality of life have yet to be been evidenced. The aim of this study was to evaluate the relationship of different levels of disease activity on the painful profile and quality of life (QOL) of patients diagnosed with RA. This was a cross-sectional study, conducted in RA patients attending an Educational Outpatient Care Service in Salvador, Bahia, Brazil. The LDA was defined according to values of Erythrocyte Sedimentation Rate (ESR), Visual Analog Scale (VAS), and number of swollen and sore joints, according to the Disease Activity Score in 28 joints (DAS28). Types of pain were assessed using the Douleur Neuropathique en 4 questions (DN4). To evaluate QOL, the Short Form (36) Health Survey (SF-36) and Health Assessment Questionnaire (HAQ) were applied. The association between LDA, QOL and painful profile was verified using One Way-ANOVA and Bonferroni correction post-test. A high LAD was observed in 67.7% of the 96 patients  evaluated in this study. Pain sensation was reported by 94.8 % of participants with 40.6 % reporting it as nociceptive and 80.2% as intense. It was also observed that the higher LAD found the higher was the pain intensity reported (p=0.001) and lower QOL scores (p<0.001). Although the LDA did not correlate with the type of pain (p=0.611), it was correlated with the total score obtained in the QOL from the HAQ (p=0.001). The greatest impact on QOL evaluated through the SF-36 were physical (p<0.001) and functional capacity (p<0.001). In conclusion, RA patients who had high LDA reported more severe pain perception and obtained the lowest scores in the assessment of quality of life.
