“…In Colombia, the National Epidemiologic Study conducted between 1995 and 1996 reported a crude prevalence of 470/100 000 for PD [5], whilst in 2004, in the same country, Sánchez et al. [6] reported a crude prevalence of 30.7/100 000 and 176.4/100 000 in a population older than 50 years in the department of Antioquia. A community‐based study in Bambui, Brazil in a cohort older than 64 years showed a prevalence of 3300/100 000 [7].…”

“…The CRM may be one of only a few techniques to accurately assess disease spread and frequency in developing countries like Thailand. This technique has been applied in many settings to estimate the distribution and prevalence of such disorders as type 2 diabetes, fetal alcohol syndrome and PD [14][15][16][17] .…”

Background: Parkinson’s disease (PD) occurs worldwide but prior to this review of data from the Thailand Parkinson’s Disease Registry there had been no nationwide PD registry reported globally. Objective: To determine the distribution and prevalence of PD in Thailand and related risk factors in order to more adequately develop and allocate prevention and treatment resources where they are most needed and to ascertain risk factors that are specific to the Thai population. Design: The Thailand Parkinson’s Disease Registry is a new resource, and data collection began in March 2008. Data is collected by the Registry from physicians, and a mechanism is also provided for patients to self-report. This data was further analyzed by the capture-recapture methodology (CRM) to assess reporting biases. Methods: The three main sources of data input to the Registry, i.e. (1) public hospitals, (2) private hospitals and (3) self-registration, require checking for duplicates and also allow estimation of completeness of recording (the degree of underreporting) in this disease registry. There is underreporting because of poor record keeping and administrative procedures in some facilities, and there is an unknown number of persons with PD who are not properly diagnosed because of inadequate facilities and staffing in some areas. Since our data sources should be overlapping in some way, and assuming that the likelihood of being detected in one system is independent of the others, we estimated these data sources’ actual coverage and the expected total number of patients utilizing the ‘capture-recapture’ statistical technique. Results: As of March 2011, the Thailand PD Registry had identified 40,049 PD patients. Employing log-linear modeling, the CRM analysis based on the three data sets estimated underreporting of 20,516 cases. The revised estimated total is thus 60,565 cases, resulting in a crude and age-adjusted prevalence of 95.34 and 424.57 PD cases/100,000 population, respectively. The prevalence of PD was 126.83/100,000 in urban areas and 90.82/100,000 in rural areas (p < 0.001). Preliminary regional comparisons revealed a higher prevalence of PD in residents of the central plain valley of Thailand, an area with a large amount of pesticide use. Conclusions: The combination of a passive registry and the CRM technique allowed us to derive population prevalence estimates for PD in Thailand. Thai PD prevalence estimates were similar to previous ones published for Asian countries; in addition, they suggested that urbanization and exposure to pesticides may both be risk factors for PD in the Thai population.

“…Therefore, data about HRQoL in South America, Africa, and Asia are scarce 11–13. In South America, specifically, most of the published papers about PD refer to epidemiological studies 14–16. Furthermore, data regarding the impact of PD in Brazil do not exist.…”

Independent validation of SCOPA–psychosocial and metric properties of the PDQ‐39 Brazilian version

The objective of this study was to perform an independent validation of the Scales for Outcomes in Parkinson's Disease-Psychosocial questionnaire (SCOPA-PS) and assessment of the Parkinson's Disease Questionnaire (PDQ-39), Brazilian version. Patients were evaluated by means of the Unified Parkinson's Disease Rating Scale, Hoehn and Yahr staging (HY), Schwab and England scale, Mini-Mental State Examination, and Hospital Anxiety and Depression Scale. Health-related quality of life was evaluated using the MOS-Short Form 36 (SF-36), PDQ-39, and SCOPA-PS. One hundred forty-four patients were included (mean age, 62 years; 53.5% males; mean duration of illness, 6.6 years; HY, 1-4). Mean SCOPA-PS and PDQ-39 Summary Index (SI) were 39.2 and 40.7, respectively. The internal consistency of SCOPA-PS (Cronbach's alpha = 0.84; item-total correlation, 0.44-0.73) and PDQ-39 dimensions (alpha = 0.61-0.85; item-total correlation, 0.46-0.82) were satisfactory. Concerning the stability of the questionnaires, intraclass correlation coefficient (ICC) values were 0.71 for the SCOPA-PS and 0.86 for the PDQ-39 SI. ICC for PDQ-39 dimensions ranged from 0.52 (social support) to 0.80 (stigma). Standard error of measurement (SEM) values for each PDQ-39 dimension ranged from 0.49 (emotional well-being) to 17.52 (social support). SEM values for SCOPA-PS and PDQ-39 SI were 11.84 and 6.72, respectively. A significant correlation of SCOPA-PS and PDQ-39 SI with the SF-36 physical (-0.42 and -0.52, respectively) and mental components (-0.41) was found. Correlation between SCOPA-PS and PDQ-39 SI was 0.73 (all coefficients, P < 0.0001). The SCOPA-PS and PDQ-39, Brazilian versions, have satisfactory metric attributes.
