Featured Application Featured Application: This study underscores the impact of osteoarthritis (OA) severity, bilateral involvement, and pain on functional impairment in older adults. The findings suggest that promoting physical activity may enhance functionality and improve the quality of life for individuals with OA. These insights can guide healthcare professionals and stakeholders in developing targeted interventions for older adults with OA. Abstract Hip and knee osteoarthritis (OA) is common among Chilean adults over 60, impacting their functionality. This study aimed to determine how health factors such as disease severity, type of OA, medication use, and physical activity levels relate to functionality in individuals with OA. The sample size included 67 women and 13 men aged 38 to 92 (66.6 ± 11.2) with diagnosed knee or hip OA. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) was used to estimate physical activity, the Lequesne Index for functional impairment, and the VAS (Visual Analog Scale) for pain. Data were collected from December 2022 to March 2023. We performed bivariate analyses, which indicated that greater OA severity and bilateral OA are associated with increased functional impairment and pain. Medication use was correlated with higher pain levels, and physical activity was correlated with functionality; there was no correlation with age. Here, 65.4% of the variance in functionality problems was explained by OA severity, bilateral involvement, and pain level, highlighting their impact on functionality. Functionality problems were higher in individuals who suffered higher levels of severity when they performed lower levels of physical activity. These findings underscore the importance of promoting physical activity to improve the quality of life for individuals with OA.

The current study aimed to examine the relationship between sociodemographic variables (i.e., sex, age, marital status, educational level, socioeconomic status, and working mode) and physical activity levels declared by Chilean adults. The sample comprised 483 Chilean adults, 159 men (32.9%) and 324 women (67.1%) aged from 18 to 69 years old (36.5 ± 12.0). The participants completed an ad hoc sociodemographic online survey between December 2022 and March 2023 that included questions about characteristics of participants such as sex, age, educational level, household income, marital status, and working mode. Vigorous, moderate, and walking activities were measured using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), a self-administered questionnaire. Men declared significantly higher vigorous and moderated physical activity than women. People aged 18 to 25, single or unmarried, and with the lowest household income, showed significantly higher scores in vigorous physical activity than those aged 26 to 45, cohabiting with a partner or married, and middle household income, respectively. Regarding working mode, people working at their job site said walking more than people not working, working in a hybrid mode, and working online. Our findings suggest that promoting strategies that increase physical activity during the pandemic is necessary to avoid health problems.

This study aimed to compare the levels of physical activity and quality of life reported by Chileans with and without osteoarthritis (OA). Educational level and monthly income data were collected from eighty-two participants (62 women and 20 men), of whom 41 had OA. Concerning the medical information of the persons suffering from OA, diseases, and date of diagnosis were indicated. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) and its Elderly version (IPAQ-E) estimated physical activity levels. The Short Form 36 Questionnaire (SF-36) assessed health-related quality of life. The findings indicate that non-OA subjects scored higher on all dimensions of the SF-36, including physical function, physical role, bodily pain, general health, vitality, social function, emotional role, and mental health. Individuals with OA reported better physical function and role, general health, vitality, social function, and mental health when they walked more. However, no associations were found between any physical activity levels and the degree of pain in people with OA. Our findings underscore the critical role of investigating physical activity in OA patients to enhance their quality of life, particularly in light of the increased sedentary behavior observed post-pandemic.
