Associations between health-related quality of life and measures of adiposity among Filipino adults.

Abstract

ObjectiveEstimate associations between the health-related quality of life (HRQoL) and adiposity in a low-income population.MethodsIn a cluster random sample of 3796 Filipinos aged 40-70 years in Nueva Ecija province, we measured body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and six dimensions of HRQoL using the 20-item Short Form Health Survey. We stratified by sex and used nonparametric regression to graph mean HRQoL in each dimension by BMI, WC, and WHR. We used ordinary least squares regression to estimate differences in each HRQoL dimension by categories of BMI, WC, and WHR adjusted for sociodemographic characteristics and smoking.ResultsMean HRQoL was lowest for health perception (Males: 67.5 (SD = 15.9); Females: 66.7 (15.8)) and highest for role functioning (Males: 97.5 (12.9); Females: 97.4 (13.3)). Mean (SD) values of BMI, WC, and WHR were 22.1 (3.6), 84.8 cm (9.5), and 0.9 (0.1), respectively for males, and 23.7 (4.2), 86.5 cm (10.2), and 0.9 (0.1), respectively, for females. There was no evidence that higher BMI was associated with lower HRQoL. Adjusted mean social functioning was 4.92 (p = 0.076) higher for males with high BMI risk (8.6% prevalence) compared with acceptable BMI risk (50.3%). Mean social functioning was 3.61 (p = 0.012) and 5.48 (p = 0.017) lower for females with high WC (44.7%) and WHR (83.1%), respectively, compared with those with low WC (23.8%) and WHR (3.6%). Mean physical functioning was lower by 2.70 (p = 0.204) and 1.07 (p = 0.198) for males and females, respectively, with high compared with low WC. Mean physical functioning was 3.93 (p = 0.037) lower for males with high (7.6%) compared with low (38.8%) WHR. Mean role functioning was 1.09 (p = 0.124) and 2.46 (p = 0.158) lower for males with borderline and high WHR, respectively.ConclusionsThere is discordance between future adiposity-related health risk and current experience of HRQoL.
