The Impact of Sarcopenic Obesity on Health-Related Quality of Life of Treatment-Seeking Patients with Obesity

BACKGROUND

There is a paucity of studies on health-related quality of life (HRQoL) and sarcopenic obesity (SO).

OBJECTIVE

This study aimed to assess the potential association between SO and impaired HRQoL.

METHODS

The ORWELL 97 questionnaire was used to assess HRQoL and body composition was measured using a bioimpedance analyser (Tanita BC-418) in 130 patients with obesity, referred to the Nutritional and Weight Management outpatient clinic of Beirut Arab University in Lebanon. Participants were then categorized on the basis of the absence or presence of SO.

RESULTS

Sixty-four of the 130 participants met the criteria for SO (49.2%) and displayed significantly higher total ORWELL 97 scores than those in the group without SO (64.00 vs. 41.00, p=0.001), indicative of poorer HRQoL. Linear regression analysis showed that SO was associated with an increase in ORWELL 97 scores by nearly 24 units (β=24.35, 95% CI=11.45-37.26; p<0.0001). Moreover, the logistic regression analysis showed that SO increased the odds of clinically significant impairment of HRQoL (ORWELL 97 score ≥74.25) by nearly seven-fold (OR=7.37, 95% CI=1.92-28.39; p=0.004).

CONCLUSION

Our findings show that the presence of SO was associated with increased impairment of HRQoL that reaches clinical significance when compared to obesity only. Future studies are needed to clarify whether this may influence clinical outcomes. If this is shown to be the case, weight management programs should incorporate additional strategies to improve HRQoL in individuals with SO.

The Association between Body Mass Index and Health-Related Quality of Life in Treatment-Seeking Arab Adults with Obesity

Few studies have thus far been carried out on Health-Related Quality of Life (HRQoL) and obesity in Arab-speaking countries, an issue that we therefore set out to investigate in this study. HRQoL was assessed by the validated Arabic version of the ORWELL 97 questionnaire in 129 treatment-seeking individuals with obesity referred to the Nutritional and Weight Management Outpatient Clinic at the Department of Nutrition and Dietetics of Beirut Arab University (BAU) in Lebanon, and 129 normal-weight participants of similar age and gender. Participants with obesity, regardless of gender, displayed higher total ORWELL 97 scores when compared with normal-weight controls, indicating that obesity is associated with lower HRQoL. Linear regression analysis showed that a higher body mass index (BMI) is associated with an increase in ORWELL 97 scores, but only among female, not male, participants with obesity (β = 2.89, 95% confidence interval (CI) = 1.43-4.53, p < 0.001). Moreover, logistic regression analysis showed that a one unit increase in BMI increases the odds of an ORWELL 97 score ≥ 71.75-considered indicative of a clinically significant impairment of HRQoL-by nearly 23% (odds ratio (OR), 95% CI = 1.23, 1.09-1.40, p < 0.05). If confirmed, our findings should prompt clinicians operating in Arab countries to encourage patients with obesity to initiate and persevere in weight-loss programs at the earliest opportunity.
