Caregiver-reported health-related quality of life of children with cerebral palsy and their families and its association with gross motor function: A South Indian study

ABSTRACT Introduction: In children, health-related quality of life (HRQOL) includes parental impact and family functioning along with concepts of illness, functional status, mental health, and comfort. We are focusing on the impact of cerebral palsy (CP) on children’s HRQOL and their families, and its relationship with gross motor dysfunction. Subjects and Methods: CP children aged 3–10 years under regular neurology follow-up were enrolled. The HRQOL and motor severity were prospectively assessed using lifestyle assessment questionnaire-CP and gross motor function classification systems, respectively. Results: One hundred children participated in this study. Thirty-three percent of children had good, 22% had mildly affected, whereas 45% had moderately to severely affected HRQOL. A significant association is present between gross motor function classification system and HRQOL. Conclusion: HRQOL in CP and their caregivers is highly impaired. The degree of impairment is associated with physical independence, mobility, clinical burden, and social integration dimensions. Therapies targeting these dimensions and associated comorbidities will improve the HRQOL. Gross motor function classification system is a good indicator of HRQOL.

Does Future Diabetes Risk Impair Current Quality of Life? A Cross-Sectional Study of Health-Related Quality of Life in Relation to the Finnish Diabetes Risk Score (FINDRISC).

ObjectivesPresent study examines the relationship between the estimated risk of developing type 2 diabetes (T2D) and health-related quality of life (HRQoL). We quantify the association between Finnish Diabetes Risk Score (FINDRISC) and HRQoL, and examine the potential use of FINDRISC as tool to evaluate HRQoL indirectly.MethodsWe conducted a cross-sectional study comprising 707 Finnish people without a diagnosis of T2D between the ages of 51 and 75 years. The risk of developing T2D was assessed using the validated and widely used FINDRISC (range 0–26 points), and quality of life was measured using two preference-based HRQoL instruments (15D and SF-6D) and one health profile instrument (SF-36). Effects of the individual FINDRISC items and demographic and clinical characteristics, such as co-morbidities, on HRQoL were studied using multivariable Tobit regression models.ResultsLow HRQoL was significantly and directly associated with the estimated risk of developing T2D. An approximate 4–5 point change in FINDRISC score was observed to be associated with clinically noticeable changes in the preference-based instrument HRQoL index scores. The association between HRQoL and the risk of developing T2D was also observed for most dimensions of HRQoL in all applied HRQoL instruments. Overall, old age, lack of physical activity, obesity, and history of high blood glucose were the FINDRISC factors most prominently associated with lower HRQoL.ConclusionsThe findings may help the health care professionals to substantiate the possible improvement in glucose metabolism and HRQoL potentially achieved by lifestyle changes, and better convince people at high risk of T2D to take action towards healthier lifestyle habits. FINDRISC may also provide an accurate proxy for HRQoL, and thus by estimating the risk of T2D with the FINDRISC, information about patients’ HRQoL may also be obtained indirectly, when it is not feasible to use HRQoL instruments.

Comparison of EQ-5D and 15D instruments for assessing the health-related quality of life in cardiac surgery patients.

Patient-centred outcomes can be measured with different instruments. We compared the performance of two health-related quality-of-life (HRQoL) measures, EQ-5D and 15D, in patients undergoing elective coronary artery bypass grafting (CABG). Patients who were admitted for elective CABG in Kuopio University Hospital Finland in 2012-14 and had completed both instruments concurrently as part of the admission process (n = 182). Follow-up was conducted by postal survey 12 months after the CABG operation. The validity, agreement, and responsiveness to change of both instruments were examined. The mean baseline HRQoL index scores obtained by the EQ-5D and the 15D were 0.795 and 0.859, respectively (P < 0.001 for difference). The agreement between instruments was poor (Spearman's rho = 0.449; P < 0.001). Observed ceiling effects at baseline for the EQ-5D and 15D were 31.9 and 4.4%, respectively. EQ-5D was able to discriminate distinct Canadian Cardiovascular Society groups. During the 1-year follow-up, clinically important improvement was observed in 39.6 and 53.3% of patients with the EQ-5D and the 15D, respectively. However, with the 15D, the number of operated patients required to produce one additional quality-adjusted life year (QALY) was more than twice as high compared with the EQ-5D. EQ-5D and 15D do not appear to be interchangeable when patient-centred outcomes in CABG patients are assessed. The EQ-5D seems to have better discriminative power and known-group validity, whereas the 15D is more sensitive to change over time. These instruments lead to significantly different estimates concerning the number of QALYs gained.

The relationship between health-related quality of life and higher-level functional capacity in elderly women with mild cognitive impairment.

[Purpose] To clarify health-related quality of life (HR-QOL) in subjects with mild cognitive impairment (MCI), using EuroQOL (EQ-5D), and to investigate the relationship between HR-QOL and Tokyo Metropolitan Institute Gerontology Index of Competence (TMIG-IC) scores. [Subjects and Methods] The subjects included 25 women with MCI or frail constitutions. A variety of methods were used to assess mental states and activities of daily living (ADL). [Results] EQ-5D scores were significantly lower in the MCI group than in the normal cognitive (NC) group. Among the assessed subscales, the percentages of participants with “moderate problems” during self-care and “moderate and extreme problems” during usual activities were significantly higher in the MCI group. TMIG-IC scores were significantly lower in the MCI group than in the NC group. There was a positive correlation between TMIG-IC and EQ-5D scores in the MCI group. There were also significant positive correlations between instrumental activities of daily living and social roles between EQ-5D and TMIG-IC scores in the MCI group. [Conclusion] TMIG-IC scores may reflect cognitive disorders earlier than BI and FIM. The decline of TMIG-IC scores, especially for IADL and social roles, affects HR-QOL even in the early phases of cognitive impairment.

Caregiver-reported health-related quality of life of children with cerebral palsy and their families and its association with gross motor function: A South Indian study.

A significant association is present between gross motor function classification system and HRQOL.Conclusion:HRQOL in CP and their caregivers is highly impaired. The degree of impairment is associated with physical independence, mobility, clinical burden, and social integration dimensions. Therapies targeting these dimensions and associated comorbidities will improve the HRQOL. Gross motor function classification system is a good indicator of HRQOL.

Health-Related Quality of Life in patients with hepatitis C treated with dual and triple therapy

Comparing Health-Related Quality of Life (HRQoL) scores in patients with chronic hepatitis C undergoing double and triple antiviral therapy and analyzing possible factors related to HRQoL. HRQoL was assessed using the Short Form 36 and Chronic Liver Disease Questionnaire, which were applied at baseline and at weeks 4, 12 and 16 of treatment to 32 patients divided into two groups: double therapy with pegylated interferon (IFN-PEG) and ribavirin, and triple therapy with PEG-IFN, ribavirin and telaprevir. The reduction of HRQoL was greater in patients receiving triple therapy compared to those treated with two drugs, the most critical time is at 12 weeks in both groups. After removal of telaprevir, the triple therapy group significantly improved their HRQoL scores. Anxiety and depression before treatment, employment status and race are significantly related to diminished HRQoL. Patients undergoing double and triple therapy have diminished HRQoL indexes, but the addition of telaprevir chooses a more significant decrease.

Social networks and health-related quality of life among Chinese old adults in urban areas: results from 4th National Household Health Survey

ObjectiveTo examine the associations between components of social networks and health-related quality of life (HRQoL) in community-dwelling old adults in urban areas in China. Study designData from the 4th National Household Health Survey (NHHS) in China, conducted in 2008, were used. HRQoL of respondents aged ≥15 years was assessed using EQ-5D in the NHHS. MethodsThe sample for the current analysis included 9833 old adults aged ≥60 years. Multiple linear and logistic regression models were used to assess the associations between indicators of social network and HRQoL. ResultsApproximately 6% of the respondents saw their children once a year or less, and approximately 1% reported that they had no children. Thirteen percent of the sample seldom contacted their neighbours and seldom met with relatives or friends; approximately 62% seldom attended social gatherings. The five dimensions of HRQoL (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) were reported to be moderate or severe in 14.5%, 9.4%, 12.6%, 18.3% and 9.3% of the sample, respectively. The mean visual analogue scale (VAS) score and EQ-5D index using the time trade-off method was 70.96 [standard deviation (SD) 14.79] and 0.869 (SD 0.163), respectively. After adjusting for potential confounding variables, old adults with weaker social networks were more likely to report problems on EQ-5D dimensions, lower VAS scores and lower EQ-5D indexes. ConclusionsFor old adults living in urban communities in China, increased social participation has a positive effect on various dimensions of HRQoL. There is a need for policy considerations that will improve integration of community-level public resources in order to encourage frequent social interaction among old adults, and promote health and social care as a whole.

Abstract 15928: A Mobile Health Driven Walking Program Improves Quality of Life but not Fitness or Fatness in Obese Sedentary Women

Background: Many mHealth programs exist for increasing physical activity (PA) yet few have been tested for their effects on fitness, fatness, and health related quality of life (HRQOL). Methods: We conducted a 3-month randomized trial that examined 2 message formats that promoted the 10,000 steps/day walking program. Women (n=70), aged 48±12 years, BMI 35.0 ±3.8, with self-report of no regular (PA), were given a FitBit and smartphone, which automatically sent daily step data to us daily. Daily messages with feedback about meeting step goals and motivation to add 500 more daily steps/week were sent to the subject’s smartphone. We compared the Multimedia Messaging Service (MMS) consisting of audio, video and graphs versus the Short Message Service (SMS), or plain text messages. Message content was the same for both groups. Outcomes included the 6-minute walk test, weight, waist and hip circumferences, BMI, SF-36, and Profile of Mood States (POMS). We hypothesized that MMS subjects would be more engaged, walk more, and attain greater gains in study outcomes. Results: We delayed messaging for the first 2 weeks to establish a daily step baseline, which was 6665 ±2270. There were no group differences in daily steps at baseline or at any time point in the study. Daily steps in Month 1 was 6926±2465; Month 2, 7327± 3310; and Month 3, 6642±2914. The increases from baseline to the full Month 1 (p=0.004) and Month 1 to 2 (p=0.025) were significant but not the decrease from Month 2 to 3. The FitBit was worn 91% of study days in both groups. There were no changes or group differences in any fitness or fatness measure. Both groups similarly improved SF-36 General Health (p=0.02) and Vitality (p=0.01); and POMS Fatigue (p=0.01), Vigor (p=0.001), Tension-Anxiety (p=0.03), and Total Mood Score, (p=0.02). Conclusions: Baseline steps were about 2-3 times more than expected for sedentary women. It seems that the novelty of using a tracking device accelerated the planned progression for walking, with a much higher than expected step count initially and then a slight drop over time. An average of 10,000 steps/day was not met. There were no changes in physical measures though indicators of HRQOL improved. Contrary to our hypothesis, the different messaging formats did not affect outcomes.

Associations of Daily Pedometer Steps and Self-Reported Physical Activity With Health-Related Quality of Life: Results From the Alberta Older Adult Health Survey.

The aim of this article is to examine associations of self-reported physical activity (PA) and pedometer steps with health-related quality of life (HRQoL) among a population-based sample of older adults. Adults ≥55 years (N = 1,296) were recruited through random-digit dialing and responded to a questionnaire via computer-assisted telephone interviewing methods. Questionnaires assessed demographic variables and validated measures of PA and HRQoL. Participants received a step pedometer and waist circumference tape measure via post. Compared with participants in the low-step group (0-6,999 steps/day), participants in the high-step group (>10,000 steps/day) had significantly higher scores on mental health (Mdiff = 3.1, p < .001, confidence intervals [CI] = [1.8, 4.3]), physical health (Mdiff = 3.5, p < .001, CI = [2.2, 4.7]), and global health (Mdiff = 3.5, p < .001, CI = [2.3, 4.7]). Waist circumference and body mass index did not moderate any associations of pedometer steps and PA with HRQoL. Older adults exceeding established step thresholds reported significantly higher HRQoL indices compared with those achieving lower thresholds.

Statistical Modeling of Disease Progression for Chronic Obstructive Pulmonary Disease Using Data from the ECLIPSE Study.

To develop statistical models predicting disease progression and outcomes in chronic obstructive pulmonary disease (COPD), using data from ECLIPSE, a large, observational study of current and former smokers with COPD. Based on a conceptual model of COPD disease progression and data from 2164 patients, associations were made between baseline characteristics, COPD disease progression attributes (exacerbations, lung function, exercise capacity, and symptoms), health-related quality of life (HRQoL), and survival. Linear and nonlinear functional forms of random intercept models were used to characterize these relationships. Endogeneity was addressed by time-lagging variables in the regression models. At the 5% significance level, an exacerbation history in the year before baseline was associated with increased risk of future exacerbations (moderate: +125.8%; severe: +89.2%) and decline in lung function (forced expiratory volume in 1 second [FEV1]) (-94.20 mL per year). Each 1% increase in FEV1 % predicted was associated with decreased risk of exacerbations (moderate: -1.1%; severe: -3.0%) and increased 6-minute walk test distance (6MWD) (+1.5 m). Increases in baseline exercise capacity (6MWD, per meter) were associated with slightly increased risk of moderate exacerbations (+0.04%) and increased FEV1 (+0.62 mL). Symptoms (dyspnea, cough, and/or sputum) were associated with an increased risk of moderate exacerbations (+13.4% to +31.1%), and baseline dyspnea (modified Medical Research Council score ≥2 v. <2) was associated with lower FEV1 (-112.3 mL). A series of linked statistical regression equations have been developed to express associations between indicators of COPD disease severity and HRQoL and survival. These can be used to represent disease progression, for example, in new economic models of COPD.

Health-related quality of life in pediatric Chiari Type I malformation: the Chiari Health Index for Pediatrics.

OBJECT The purpose of this study was to design and validate a patient-reported health-related quality of life (HRQOL) instrument for pediatric Chiari Type I malformation (CM-I), the Chiari Health Index for Pediatrics (CHIP). METHODS The CHIP has 45 items with 4 components making up 2 domain scores, physical (pain frequency, pain severity, nonpain symptoms) and psychosocial; physical and psychosocial scores are combined to create an overall HRQOL score. Increasing scores (0 to 1) represent increasing HRQOL. Fifty-five patients with CM-I (mean age 12 ± 4 years, 53% male) were enrolled and completed the CHIP and Health Utilities Index Mark 3 (HUI3). Twenty-five healthy controls (mean age 11.9 ± 4 years, 40% male) also completed the CHIP. CHIP scores were compared between these groups via the Mann-Whitney U-test. For CHIP discriminative function, subscore versus presence of CM-I was compared via receiver operating characteristic curve analysis. CHIP scores in the CM-I group were stratified by symptomatology (asymptomatic, headaches, and paresthesias) and compared via Kruskal-Wallis test with Mann-Whitney U-test with Bonferroni correction (p < 0.0167). CHIP was compared with HUI3 (Health Utilities Index Mark 3) via univariate and multivariate linear regression. RESULTS CHIP physical and psychosocial subscores were, respectively, 24% and 18% lower in CM-I patients than in controls (p < 0.001); the overall HRQOL score was 23% lower as well (p < 0.001). The area under the curve (AUC) for CHIP physical subscore versus presence of CM-I was 0.809. CHIP physical subscore varied significantly with symptomatology (p = 0.001) and HUI3 pain-related quality of life (R(2) = 0.311, p < 0.001). The AUC for CHIP psychosocial subscore versus presence of CM-I was 0.754. CHIP psychosocial subscore varied significantly with HUI3 cognitive- (R(2) = 0.324, p < 0.001) and emotion-related (R(2) = 0.155, p = 0.003) quality of life. The AUC for CHIP HRQOL versus presence of CM-I was 0.820. Overall CHIP HRQOL score varied significantly with symptomatology (p = 0.001) and HUI3 multiattribute composite HRQOL score (R(2) = 0.440, p < 0.001). CONCLUSIONS The CHIP is a patient-reported, CM-I-specific HRQOL instrument, with construct validity in assessing pain-, cognitive-, and emotion-related quality of life, as well as symptomatic features unique to CM-I. It holds promise as a discriminative HRQOL index in CM-I outcomes assessment.

Longitudinal Association Between Body Mass Index and Health-Related Quality of Life.

Objective: Health-related quality of life (HRQoL) is an important outcome in individuals with a high risk for cardiovascular diseases. We investigated the association of HRQoL and body mass index (BMI) as an indicator for obesity. Design: Secondary longitudinal analysis of the ORBITAL study, an intervention study which included high-risk cardiovascular primary care patients with hypercholesterolemia and an indication for statin therapy. Methods: HRQoL was determined with the generic Short Form (SF)-12 health status instrument. Body weight and height were assessed at baseline and at months 6, 12, 18, 24, 30, and 36. We used a linear and a linear mixed-effects regression model to investigate the association between BMI and SF-12 summary scores at baseline as well as between change in BMI and SF-12 summary scores over 3 years. We adjusted for age, sex, smoking status, and in the longitudinal analysis also for the study arm and its interaction term with time. Results: Of the 7640 participants who completed the baseline questionnaire, 6726 participants (mean age: 61 years) were analyzed. The baseline BMI was inversely associated with physical and mental SF-12 summary scores (b [95% CI] per 1 kg/ m: 20.36 [20.41; 20.30] and 20.05 [20.11; 20.00], respectively). A significant association between the change in BMI and physical SF-12 summary scores over time was only present in women (20.18 [20.27; 20.09]) and only in obese participants (20.19 [20.29; 20.10]). A change in BMI was directly associated with mental SF-12 summary scores (0.12 [0.06; 0.19]) in the total population. Conclusion: Increases in BMI were associated with decreases in physical HRQoL, particularly in obese individuals and in women. In contrast, the mental HRQoL seemed to increase with increasing BMI over time. Thus, body weight management with respect to the HRQoL should be evaluated differentially by sex and body weight status.

Feasibility Study: Colombian Caribbean Folk Dances to Increase Physical Fitness and Health-Related Quality of Life in Older Women.

The objectives of the study were to describe the feasibility of an intervention in older women based on folk dances of the Colombian Caribbean region, and to analyze the effects of the intervention on physical fitness and health-related quality of life (HRQoL). A pilot study was conducted in a sample of 27 participants, 15 in the intervention group (IG) and 12 in the comparison group (CG). Caribbean Colombian dance rhythms were introduced as an intervention that lasted 12 weeks. Recruitment and retention was not optimal. Treatment fidelity components indicated that intervention was administered as intended. IG participants showed positive and statistically significant changes in some components of physical fitness. No significant changes were observed in HRQoL indicators for either group. In conclusion, the intervention was feasible, but recruitment and retention was challenging. Folk dances of the Colombian Caribbean region provoked significant results in physical fitness but not in HRQoL.

Impact of Alzheimer’s disease on the family caregiver’s long-term quality of life: results from an ALSOVA follow-up study

To examine caregivers' health-related quality of life (HRQoL) and well-being during the first 3 years after their family member's Alzheimer's disease (AD) diagnosis and assessed the relationship between caregivers' HRQoL, well-being, and the severity of AD. Further, to compare of caregivers' HRQoL to general population. Longitudinal design (36 months) after AD diagnosis of 236 caregiver-patient dyads. Linear regression was used to assess age- and gender-adjusted association between repeated measurements of caregivers' HRQoL and the severity of AD. For comparison with general population, the National Health 2011 Health Examination Survey data was utilized. Caregivers had significantly lower HRQoL than age- and gender-standardized counterparts. Severity of AD was significantly (p < 0.05) associated with the mobility and depression dimensions of caregiver's HRQoL but not with the total HRQoL index score. Caregivers' HRQoL seems to deteriorate earlier than previously noted. The severity of AD has not that great impact on caregiver's HRQoL as assumed.

Heterogeneous Determinants of Quality of Life in Different Phenotypes of Parkinson's Disease.

ObjectivesHealth-related quality of life (HRQoL) is considered a very important outcome indicator in patients with Parkinson’s disease (PD). A broad list of motor and non-motor features have been shown to affect HRQoL in PD, however, there is a dearth of information about the complexity of interrelationships between determinants of HRQoL in different PD phenotypes. We aimed to find independent determinates and the best structural model for HRQoL, also to investigate the heterogeneity in HRQoL between PD patients with different phenotypes regarding onset-age, progression rate and dominant symptom.MethodsA broad spectrum of demographic, motor and non-motor characteristics were collected in 157 idiopathic PD patients, namely comorbidity profile, nutritional status, UPDRS (total items), psychiatric symptoms (depression, anxiety), fatigue and psychosocial functioning through physical examination, validated questionnaires and scales. Structural equation model (SEM) and multivariate regressions were applied to find determinants of Parkinson’s disease summary index (PDSI) and different domains of HRQoL (PDQ-39).ResultsFemale sex, anxiety, depression and UPDRS-part II scores were the significant independent determinants of PDSI. A structural model consisting of global motor, global non-motor and co-morbidity indicator as three main components was able to predict 89% of the variance in HRQoL. In older-onset and slow-progression phenotypes, the motor domain showed smaller contribution on HRQoL and the majority of its effects were mediated through non-motor features. Comorbidity component was a significant determinant of HRQoL only among older-onset and non-tremor-dominant PD patients. Fatigue was not a significant indicator of non-motor component to affect HRQoL in rapid-progression PD.ConclusionsOur findings showed outstanding heterogeneities in the pattern and determinants of HRQoL among PD phenotypes. These factors should be considered during the assessments and developing personalized interventions to improve HRQOL in PD patients with different phenotypes or prominent feature.

Objectively measured physical activity and sedentary behavior and quality of life indicators in survivors of breast cancer.

The primary purpose of the current study was to determine prospective associations of accelerometer-assessed physical activity intensity and sedentary time with health-related quality of life (HRQOL) indicators among survivors of breast cancer. A total of 358 survivors of breast cancer wore an accelerometer for 7 days at baseline to assess different activity intensities (light, lifestyle, and moderate to vigorous) and sedentary behavior. Six months later, survivors completed online questionnaires that assessed HRQOL indicators (disease-specific HRQOL, fatigue, depression, and anxiety) and relevant covariates. Relationships between activity and sedentary behavior quartiles and HRQOL indicator scores were examined using generalized liner models with Bonferroni multiple comparison adjustment. After adjustment for covariates and sedentary time, each increasing lifestyle activity quartile was associated with reduced fatigue duration (P for trend, .03). Each increasing baseline moderate-to-vigorous physical activity (MVPA) quartile was found to be significantly associated with higher Physical Well-Being, Functional Assessment of Cancer Therapy-Breast (FACT-B) total, and trial outcome index scores; fewer breast cancer-specific concerns; and lower fatigue interference, and these differences were statistically and clinically significant between survivors in quartile 1 and quartile 4. After controlling for covariates and MVPA, relationships between sedentary time and HRQOL were mostly null with the exception of lower fatigue duration. Objectively measured MVPA was found to be positively associated with many HRQOL indicators. Lifestyle activity was found to be only inversely associated with fatigue duration whereas sedentary time was found to be positively associated with fatigue duration. Future research is warranted to explore these relationships further.

Cross-cultural adaptation to Portuguese of a measure of satisfaction with participation of the Patient-Reported Outcomes Measurement Information System (PROMIS(r)).

Mental disorders often impair functioning in several areas of life and lead to unhappiness and suffering that may affect health-related quality of life (HRQoL). Satisfaction with participation is an indicator of HRQoL, and its measurement by patients reflects the impact of disease on their social, emotional and professional life. The Patient-Reported Outcomes Measurement Information System (PROMIS(r)) offers an item bank based on item response theory. This system provides efficient, reliable and valid self-report instruments of satisfaction with participation, a measure that is both scarce and useful in the assessment of mental disorder outcomes. To cross-culturally adapt the PROMIS(r) satisfaction with participation item bank to Portuguese. Cross-cultural adaptation followed the Functional Assessment of Chronic Illness Therapy (FACIT) multilingual translation method and was achieved through steps of forward and backward translations, review by bilingual experts (one of them a native of Portugal) and pretesting in a group of 11 adult native Brazilians. Instrument adaptation followed a universal approach to translation, with harmonization across languages. Equivalence of meaning was achieved. As two of the 26 translated items, which asked about leisure and social activities, were not understood by less educated participants, an explanation in parentheses was added to each item, and the problem was solved. All items were appropriate and did not cause embarrassment to the participants. The satisfaction with participation item bank is culturally and linguistically suitable to be used in Brazil. After the pretest is applied in Portugal and in other Portuguese-speaking countries, the same instrument will be ready to be used in multinational studies.

Health-related quality of life is associated with stroke deficits in older adults.

although the functional impairments of stroke survivors are associated with poor health-related quality of life (HRQoL), few studies have demonstrated the impact of individual stroke deficits on the quality of life of survivors. In this study, we investigated the association between HRQoL and stroke-related deficits, especially with respect to the number and types of deficits, in older adults. the data were obtained from the 2008 and 2009 Korean Community Health Survey. The EuroQoL 5 Dimension (EQ-5D) questionnaire used as the HRQoL index, and stroke-related information included the number of stroke deficits and five types of deficits. of the 122,095 participants, 6,698 (5.5%) subjects had a history of stroke, of whom 2,222 patients (33.2%) reported one or more stroke-related deficits. After adjustments for potential variables, the EQ-5D scores of the stroke survivors with persisting deficits were significantly reduced as the number of stroke deficits increased (β = -0.080, -0.147, -0.229, -0.252 and -0.293 for one, two, three, four and five deficits, respectively). The type of stroke deficits was associated with the level of HRQoL. Specifically, the adjusted EQ-5D score of patients who suffered from hemiplegia (β = -0.143; P value < .00001) was worse than that of patients with any stroke deficits. The most frequent problems were related to mobility and pain/discomfort, regardless of the number or type of stroke deficits. we found that impaired HRQoL was significantly associated with the number and type of stroke deficits in older adults with a history of stroke.

Analyzing Food-Related Life Satisfaction and other Predictors of Life Satisfaction in Central Chile.

This study aimed to assess the effect of satisfaction with food-related life on life satisfaction among inhabitants of the main municipalities of central Chile. A survey was applied to a sample of 1,277 people, distributed proportionally by municipality. The questionnaire included the following scales: SWLS (Satisfaction with Life Scale), SWFL (Satisfaction with Food-related Life) and the Health-Related Quality of Life Index (HRQOL). Questions were asked regarding eating habits inside and outside the home, time available for meals at home, the assessment of five sources of happiness and the demographic characteristics of those surveyed. An ordered logit model was proposed, in which the dependent variable was satisfaction with life. Satisfaction with life was significantly related to the respondent's socioeconomic status, self-perception of health, degree of satisfaction with food-related life, monthly food expenditure, time available for supper with the family (p < .01); gender, self-reported number of days affected by mental health problems, frequency of supper with the family, the degree of agreement with respect to family being an important source of happiness (p < .05); and family size and frequency of food consumption in fast food outlets (p < .10). Satisfaction with life in the study sample is related to aspects associated with health, family and eating, and the family interaction associated with eating may play an important role in overall satisfaction with life.

Joint associations of objectively-measured sedentary behavior and physical activity with health-related quality of life.

No studies, to my knowledge, have examined the joint effects of physical activity and sedentary behavior on health-related quality of life (HRQOL), which was the purpose of this study. Data from the 2003–2006 National Health and Nutrition Examination Survey (NHANES) were used (N = 5,536). Moderate-to-vigorous physical activity (MVPA) and sedentary behavior were assessed using an ActiGraph 7164 accelerometer, with HRQOL assessed using the Centers for Disease Control and Prevention 4-item HRQOL index. MVPA (βadjusted = − 0.01; 95% CI: − 0.01 to − 0.004; P < 0.001), but not sedentary behavior (βadjusted = − 0.0003; 95% CI: − 0.001–0.0001; P = 0.37), was associated with HRQOL. MVPA was associated with HRQOL among those above the median (≥ 487.5 min/day) level of sedentary behavior (βadjusted = − 0.02; 95% CI: − 0.03 to − 0.01; P = 0.006; N = 2769). The results of this brief report do not demonstrate that sedentary behavior, independent of MVPA, is associated with HRQOL. The independent association of MVPA on HRQOL confirms previous work that used self-report measures of MVPA.
