The Impact of Osteoarthritis on the Functioning and Health Status of a Low-Income Population: An Example of a Disability Paradox.

OBJECTIVE: The aim of this study was to measure the impact of osteoarthritis on the functioning and health status of individuals living in a low-income urban community in Mexico. METHODS: We conducted a cross-sectional, community-based study from December 2014 to November 2015, using the Community Oriented Program for Control of Rheumatic Diseases methodology to identify cases of musculoskeletal disease in a sample of adults older than 18 years in Pueblo Nuevo, Apodaca, Mexico. Two rheumatologists confirmed all cases of osteoarthritis (OA) using predefined criteria. Functioning was evaluated through (a) self-report of difficulty doing personal care, work, and leisure activities; (b) the modified Stanford Health Assessment Questionnaire-Disability Index; and (c) the Timed Up and Go test. Health status was evaluated using the EuroQoL 5 Dimensions. Statistical analyses were performed using χ tests and logistic regression models. RESULTS: Four hundred thirty-nine individuals with a mean age of 45.2 years were included, and 83 cases of OA were confirmed. The presence of OA was not significantly associated with having difficulties to do personal care, work, or leisure activities, but it was significantly associated with a higher Health Assessment Questionnaire-Disability Index score, longer time to complete the Timed Up and Go, and lower health status. CONCLUSIONS: Osteoarthritis is associated with having higher disability and worse health status in the community studied. A disability paradox was detected as some individuals perceived disability for doing standard activities but did not present disability performing their real-life activities. This underlies the importance of addressing the mental dimension during the management of this population.

Social determinants of hypertensive disorders of pregnancy trends in Mexican municipalities.

OBJECTIVES: To analyze the hypertensive disorders of pregnancy (HDP) trends in the 2000-2020 period and its association with social determinants of health (SDH) in Mexican municipalities. STUDY DESIGN: This was a retrospective longitudinal study analyzing data from routine information systems on 21,493,076 hospital discharges due to maternal causes and SDH data of 2,439-2,450 municipalities between 2000 and 2020. MAIN OUTCOMES MEASURES: We used joinpoint regression models to analyze HDP trends and hybrid negative binomial regression models to examine the association between SDH and HDP rates at intra- and inter-municipality levels. RESULTS: HDP rate increased from 0.54 in 2000 to 2.42 cases per 100 live births in 2020 (annual average percent change of 7.7 %, 95 % CI 6.6-8.9). Municipalities with higher marginalization index had higher HDP rates (IRR 1.12, 95 % CI 1.01-1.24; 1.36, 95 % CI 1.25-1.47; 1.30, 95 % CI 1.23-1.37, and 1.06, 95 % CI 1.00-1.12, in 2000-2004, 2005-2009, 2010-2014, 2015-2020, respectively). Municipal increases in the percentage of population with high schooling were associated with decreases in HDP rates in 2000-2009. Meanwhile, the role of socioeconomic status at the state level was less consistent, yet the HDP rates were lower in most socially advantaged regions. CONCLUSION: During 21 years, HDP rates increased overall in Mexican municipalities, suggesting an increased maternal morbidity burden due to HDP. The association of municipal marginalization and socioeconomic level with HDP trends indicates a need to ensure equitable interventions to improve maternal health in Mexican municipalities.
