Quality of Life among Adults with Confirmed Dengue in Brazil

Abstract

Abstract. The main objective of this study was to measure the quality of life (QoL) during a dengue episode. We conducted a facility-based survey in central Brazil in 2005 and recruited 372 laboratory-confirmed dengue patients greater than 12 years of age in hospital and ambulatory settings. We administered the World Health Organization QoL instrument approximately 15 days after the onset of symptoms. We used principal component analysis with varimax rotation to identify domains related to QoL. The median age of interviewees was 36 years. Most (85%) reported their general health status as very good or good before the dengue episode. Although ambulatory patients were mainly classified as having dengue fever, 44.8% of hospitalized patients had dengue hemorrhagic fever or intermediate dengue. Principal component analysis identified five principal components related to cognition, sleep and energy, mobility, self-care, pain, and discomfort, which explained 73% of the variability of the data matrix. Hospitalized patients had significantly lower mean scores for dimensions cognition, self-care, and pain than ambulatory patients. This investigation documented the generally poor QoL during a dengue episode caused by the large number of domains affected and significant differences between health care settings.

Health-Related Quality of Life after Dengue Fever, Morelos, Mexico, 2016–2017

“…HRQOL decreased abruptly during the febrile phase; most patients then steadily recovered, with some exceptions for those who had not reached baseline HRQOL at 6 months. Other studies have found larger reductions of HRQOL than we found; mean EQ-VAS score was 7 for children 0-14 years of age in Cambodia (13) and 10 for hospitalized patients and 20 for ambulatory patients in Brazil (7). Our findings were comparable to those of Armien et al (14) in Panama (EQ-VAS 35.2 for children; 31.9 for adults).…”

The COPD assessment test and St George's Respiratory Questionnaire: are they equivalent in subjects with COPD?

“… 25 The internal consistency result of the CAT in this study is consistent with the findings of previous studies. With respect to univariate correlations between CAT and SGRQ scores, in previous studies, correlation coefficients ( R ) between CAT and SGRQ total scores were 0.73–0.84, 5 , 23 while Gupta et al 25 reported 0.72–0.74. Although the correlation coefficient reported herein is lower ( R =0.668), it is close to the bottom end of the range reported by other researchers.…”

“… 21 In addition, PCA was performed to identify components that best describe patient’s health and to identify groups of variables that best correlate with each component, by examining the relative contribution of the variables described earlier to CAT and SGRQ total scores. 22 , 23 A P -value of less than 0.05 was considered to be statistically significant.…”

Psychometric evaluation of the Chinese version of the revised illness perception questionnaire for breast cancer-related lymphedema

“…The Kaiser–Meyer–Olkin (KMO) was found to be 0.830, exceeding the recommended value of 0.6; and Barlett's sphericity test was significant (χ 2 = 2456.88, df = 231, p < 0.001), both indicating that EFA was appropriate for this sample (Martelli et al., ). In the initial analysis, six factors were produced, whereas one factor had only one item (C4, “poor medical care in my past”).…”
