Obesity and health related quality of life in the general adult population of the Canary Islands.
OBJECTIVE
To explore the relationship between excess weight and health related quality of life (HRQL) in the general population by means of the EuroQol-5D questionnaire.


METHODS
The relationship between excess weight and HRQL was explored by the 2004 Canary Islands Health Survey. Survey participants from 16 years of age and older were classified according to their body mass index (BMI). The relationship between excess weight and the dichotomized EuroQol-5D was examined by multiple logistic regression analysis, adjusting by socio-demographic variables, smoking status, alcohol consumption, and self-reported disease status.


RESULTS
People with excess weight were older, less educated, and had more associated diseases than the population without excess weight. Excess weight and HRQL are inversely correlated. Severely obese participants showed EuroQol-5D index scores significantly lower than those of normal weight participants (0.65 vs. 0.87). The adjusted odds ratio for the lower HRQL is 3.17 for severely obese people compared to normal weight people.


CONCLUSIONS
Excess weight has a negative impact on HRQL, even for people without chronic diseases. A better understanding of the relationships between excess weight, its associated comorbidities, and HRQL may have important implications for the design and assessment of prevention and treatment strategies.
