Background: Health-related quality of life (HRQoL) is defined as the patient´s perception of their health status. It can be modified by illnesses, treatments, social and health policies and chronic pain, wich causes low quality of life, suffering and disability. Knowing potential quality of life variations of subjects with chronic musculoskeletal symptoms (MSS), will provide information to health teams and organizations associated with the management of the Chilean health system.
Purpose: To determine the relationship among HRQoL, measured through SF-12, in Chilean population without MSS, acute MSS (aMSS) and chronic MSS (cMSS), according to age, sex, educational level and area of residence, through a secondary data analysis of the 2009-10 Chilean National Health Survey (NHS).
Methods: A secondary analysis of the Chilean NHS 2009-10 database was carried out; primary study conducted in households with a national, probabilistic, stratified and multistage sample of 5,293 people aged 15 and over, between October 2009 and September 2010. The sample was representative at the national, urban-rural and regional levels, and it was calculated with 20% relative error for the estimation of national prevalence over 4%. The MSS and HRQoL information from the 2009-10 NHS database were measured through the CCQ-ILAR and SF-12 respectively. The relation of HRQL, in its physical (PCS) and mental scores (MCS), with cMSS, aMSS and without MSS were established. A multivariate logistic regression model was used to study the relationship between cMSS and quality of life scores, adjusted by control variables. A 5% level of significance was considered, and the statistical package STATA 15 was used for all analyses.
Results: The HRQoL score values, in its PCS and MCS dimensions, showed statistically significant differences in the three MSS groups (p 0.001). The PCS and MCS scores are lower in cMSS than in aMSS, and the scores of both dimensions are lower in the two groups before mentioned when compared with those without MSS. In subjects with cMSS, the prevalence of "Low HRQoL" in its physical dimension is 50.5% and in its mental dimension of 39.7%. Presence of cMSS is a risk factor for low HRQoL; those results are showed in physical dimension (OR 3.1 95% CI 2.7-3.5) and in mental dimension (OR 1.9 95% CI 1.6-2,), independent of control variables.
Conclusion(s): Physical and mental HRQoL are affected in people with cMSS, women, low educational level, and older adults. These results provide information that will facilitate the assessment and treatment of cMSS as a prevalent and multidimensional health problem.
Implications: The high impact of the presence of cMMS on health-related quality of life in Chilean population, and the knowledge of which sociodemographic groups are most affected by this condition, provides relevant information regarding the need to establish cMMS management policies and the existing training gap for health professionals facing this epidemiological and clinical problem.
