Background: The influence of socioeconomic status (SES)
on weight status varies depending on the countries'
levels of social and economic development. There are many
studies on a risk of adolescent obesity according
to familial SES in Korea. However, it is not clarified what
effects familial SES has on a risk of underweight in
Korean adolescents. This study investigated the distribution
of weight status including obesity and underweight
according to familial SES in Korean adolescents.
Methods: This cross-sectional study involved 63,741
adolescents who participated in the 2016 Korea Youth
Risk Behavior Wed-based Survey. The data on height,
weight, familial SES, current smoking status, current
al￾cohol intake, physical activity, breakfast skipping,
perceived stress, depressive mood, and living with family
were obtained through online questionnaires. The
assessment of familial SES was based on perceived
house￾hold economic status and parental education level.
Results: In boys, low household economic status was related
to a high proportion of obesity (odds ratio [OR]
1.14, 95% confidence interval [CI] 1.04-1.25) and
underweight (OR 1.31, 95% CI 1.14-1.51). Girls with low
household economic status were more likely to be obese
(OR 1.81, 95% CI 1.61-2.03) and overweight (OR
1.41, 95% CI 1.23-1.60) but, although not statistically
significant, less likely to be underweight (OR 0.88, 95%
CI 0.75-1.04).
Conclusions: This study showed that adolescents with low
familial SES were at a high risk of obesity and
underweight. A risk of underweight was increased in boys
with low familial SES but in girls with high familial SES.
