Health Predictors of Pain in Elderly-A Serbian Population-Based Study

Unlocking the Potential of the Elderly Population in Serbia: A Modeling Study on Musculoskeletal Disorders and Associated Factors

Background/Objectives: A properly functioning musculoskeletal system is imperative for human well-being at every stage of life, including at an older age. This study's aim was to assess the relationship between sociodemographic and physical functioning variables and the presence of individual musculoskeletal disorders (MSDs), MSD comorbidity, and multimorbidity, as well as to determine factors that are independent predictors of the presence of MSDs in people over 65 years old. Methods: This population-based study included 3701 participants aged 65 years and older. Data on individual MSDs addressed cervical and lumbosacral spine regions and degenerative joint disease (arthrosis). The subjects were categorized into four groups: those without any diseases; those with one MSD; those with two MSDs (comorbidities); and those with three MSDs (multimorbidities). The sociodemographic and physical functioning variables were analyzed. Results: Females were more likely to have MSDs (two: OR 1.95 and three: OR 2.25) than men. Elderly people aged 75 and above were 1.49 times more likely to have three MSDs. Elderly people with elementary school education were more likely to have MSDs (two: OR 1.34 and three: OR 2.06) than those with high school/university education. The low-income population was 2.47 times more likely to have three MSDs. Individuals with partial activity limitations because of health problems had greater chances of having one, two, or three MSDs (OR 1.60, 1.59, and 1.94, respectively), and elderly individuals with severe limitations had an OR of 1.43, 2.17, and 4.12, respectively. Individuals with some/many difficulties in walking up or down 12 steps were more likely to have MSDs (two: OR 2.26 and three: OR 2.28). Conclusions: The significant predictors of experiencing a single MSD, MSD comorbidity, or MSD multimorbidity include residing in the Serbian capital city and having limitations in activities due to health problems. A significant predictor of having a single MSD or MSD comorbidity is residing in the northern region of Serbia. A significant predictor of MSD comorbidity is residing in the southeastern region of Serbia. Significant predictors of MSD comorbidity or MSD multimorbidity include female gender, an elementary school educational level, and experiencing difficulty in walking up or down 12 steps. Significant predictors of MSD multimorbidity are being 75 years of age and above and having a lower income.

Sociodemographic predictors of pain in old people : Serbian population-based study

BACKGROUND

With the growing increase in the older proportion of the world population, there is also an increase in specific age-related chronic diseases and conditions, including pain. We aimed to evaluate the association of sociodemographic factors with the presence and different degrees of pain intensity in people aged 65 years and older.

METHODS

The population-based study, conducted in 2013, included 3540 individuals from Serbia. As pain predictors, we analyzed further sociodemographic characteristics: gender, age, body mass index, level of education, marital status, and wealth index. For pain assessment, we used the pain domain of the SF-36 version 2.0 questionnaire.

RESULTS

People over the age of 85 years are 27% more likely to have moderate pain than younger respondents; however, pain is less likely reported by men (by 42%), persons with overweight (by 23%) or obesity (by 21%), respondents with secondary (by 50%) or university education (29%), as well as those belonging to the upper household wealth index (by 22%), than by their counterparts.

CONCLUSION

Pain is less likely in people of age below 85 years, male gender, those with higher educational level and higher wealth index, as well as overweight or obese individuals. Also, we have demonstrated that sociodemographic predictors differently correlate with the onset of the pain and its severity degree in persons of 65 years and older.
