Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Introduction: It is estimated that by 2025 there will be approximately 1.2 billion people above 60 years old. Global projections indicate that by 2050 there will be about 2 billion elders, 80% of them living in developing countries. Researches on the relationship between pain and aging are currently much valued within the health sciences, the ultimate goal being the provision of adequate pain control for the growing number of elders in society. Objectives: To characterize chronic pain in the elderly population and evaluate pain threshold to mechanical stimulation, with emphasis on gender differences. Methods: This study refers to a cross-sectional study to be conducted in convenience samples of a primary care unit (Geraldo Horacio de Paula Souza) that follows elders and the Department of Geriatrics of the university hospital of the School of Medicine of Universidade de São Paulo (Hospital das Clínicas). At least 200 participants of each gender, aged 65 or above, will be selected to participate. Chronic pain will be that lasting for six or more months (either continuous or recurrent, as recommended by the International Association For the Study of Pain). Participants will be searched about their demographic and socioeconomic backgrounds, and asked to answer the following questionnaires: the Mini Mental State Examination, a structured questionnaire for activities of daily living, a structured questionnaire for instrumental activities of daily living, Beck Anxiety Inventory, Geriatric Depression Scale, the five dimensions European Quality of Life assessment (EQ5D) and Brief Pain Inventory. Participants will also be evaluated regarding pain threshold to mechanical stimuli using algometer. Descriptive statistics of the sample will be displayed as means, medians, standard deviations and proportions. For testing for differences between males and females, a significance level of 5% will be used. Keywords: elderly, chronic pain, gender.
