Gender and age differences in the impact of overweight on obesity-related quality of life among Korean adults

SummaryObjectiveTo investigate gender and age difference in impact of overweight on health-related quality of life (HRQOL) among Korean adults.MethodsCross-sectional obesity-related quality of life (QOL) scores were measured by a Korean obesity-related QOL scale (KOQOL) from 448 Korean adults aged 20–80 years. A body mass index (BMI) was categorized with normal-weight as BMI < 23 kg/m2, overweight as BMI ≥ 23 kg/m2 based on the alternative cutoff points for Asians. Each gender was respectively stratified by median age, 45 years for men and 50 years for women, to examine the obesity-related QOL by age groups.ResultsWomen had a poorer obesity-related QOL compared to men (p < 0.001). In the younger age group, overweight women had a poorer obesity-related QOL compared with normal-weight women (p < 0.001), however normal-weight and overweight men showed no difference in obesity-related QOL. In the older age group, overweight men showed better QOL on the domains of work-related and psychosocial health than those for normal-weight men, but overweight women still suffered from work-related and routine life QOL.ConclusionsThis study showed the impact of overweight on obesity-related QOL was different for gender and age group. We should consider the results to manage weight in overweight persons.
