Background. Most EQ-5D-3L valuation studies include the same sample of health states that was used in the protocol of the original UK Measurement and Valuation of Health (MVH) study. Thus far, no studies using a time tradeoff utility elicitation method have been carried out using all 243 EQ-5D health states. Because the values and preferences regarding health outcomes differ among countries, it is essential to have country-specific data to enable local high-level decisions regarding resource allocation. This study developed a country-specific set of values for EQ-5D-3L health states. Methods. A multicentric study was conducted in 4 Brazilian areas. A probabilistic sample of the general population, aged 18 to 64 y, stratified by age and gender, was surveyed. The interview followed a revised version of the MVH protocol, in which all 243 health states were valued. Each respondent ranked and valued 7 health states using the TTO in a home interview. Results. Data were collected from 9148 subjects. The best-fitting regression model was an individual-level mixed-effects model without any interaction terms. The dimensions “Mobility” and “Usual Activities” were associated with higher losses in health state utility value. The “Anxiety/Depression” dimension was the domain that contributed to lower losses in health state utility value. Conclusions. This study generated significant insight into the Brazilian population’s health preferences that can be applied to health technology assessment and economic analyses in Brazil. This information represents an important new tool that can be used in Brazilian health policy creation and evaluation.
The objective of this study was to provide normative SF-36 scores in a general population sample in Brazil and to describe differences in mean scores according to socio-demographic characteristics. The SF-36 questionnaire was distributed to a randomly selected sample of the general population of Porto Alegre in the State of Rio Grande do Sul. The response rate was 68% and 755 subjects were included (38% male, 62% female). Lower health status was revealed among females in the 30 to 44 year age bracket, from the lower income class, with less education and self-reported chronic medical conditions. The results and percentiles of scores of the SF-36 are reported as normative data for the general population. The SF-36 was an acceptable and practical instrument for measuring health-related quality of life in a sample of Brazilians. The results of this study can be useful for researchers using the SF-36 questionnaire in other groups to compare the scores with normative data. The SF-36 may prove a valuable tool for discovering vulnerable groups in epidemiological studies due to the ability to discriminate between different population subgroups.
Germline TP53 mutations predispose individuals to multiple cancers and are associated with Li-Fraumeni/Li-Fraumeni-Like Syndromes (LFS/LFL). The founder mutation TP53 p.R337H is detected in 0.3% of the general population in southern Brazil. This mutation is associated with an increased risk of childhood adrenal cortical carcinoma (ACC) but is also common in Brazilian LFS/LFL families. Breast Cancer (BC) is one of the most common cancers diagnosed in TP53 mutation carriers. We have assessed the prevalence of p.R337H in two groups: (1) 59 BC affected women with a familial history (FH) suggestive of hereditary cancer syndrome but no LFS/LFL features; (2) 815 BC affected women unselected for cancer FH, diagnosed with BC at or before age 45 or at age 55 or older. Among group 1 and group 2 patients, 2/59 (3.4%, CI95%: 0.4%–11.7%) and 70/815 (8.6%, CI95%: 6.8%–10.7%), respectively, were p.R337H carriers in the germline. The prevalence of p.R337H was higher in women diagnosed with BC at or before age 45 (12.1%, CI95%: 9.1%–15.8%) than at age 55 or older (5.1%, CI95%: 3.2%–7.7%), p<0.001). The Brazilian founder p.R337H haplotype was detected in all carriers analysed. These results suggest that inheritance of p.R337H may significantly contribute to the high incidence of BC in Brazil, in addition to its recently demonstrated impact on the risk of childhood ACC.
