This study was conducted to examine the effect of children`s dietary quality, dietary habits, food behavior and health-related lifestyles according to the mother`s lifestyles of health and sustainability (LOHAS). The subjects were 580 children. Mother`s LOHAS attitude index was 66.85 points and 100 points was a perfect score. The mother`s high LOHAS attitude items that children perceived were "My mother often communicates with the family" (3.99 points) and "My mother thinks that the family`s health is more important than her health" (3.93 points). In contrast, the LOHAS attitude items for "My mother does community service activity on weekends" (2.78 points), and "My mother participates in environmental protection service activity for the local community" (2.78 points) were very low. The high LOHAS behavior index of mothers was "resource saving", whereas "social welfare" scored low. When self-perceived health status and monthly income of children was high, the mother`s LOHAS score was high. The LOHAS attitude index of mothers had a meaningful impact on the children`s dietary quality, dietary habits, food behavior and health-related lifestyles. The most frequent food behavior variables were "high skipping rate", "frequency of snacks is 2~4 times per week", "speed of eating is rapid", and ``meals`` amount is sufficient. The highest daily life habits item was "I try to maintain a pleasant and enjoyable life style" (3.42 points). The highest nutrient intake attitude score was "I tend to eat rice everyday." (3.41 points). They were highly recognized with "moderate physical activity", "high exercise preference", "positive posture exercise", "exercise <2 days per week", and "over 30 minutes exercise time per day" for the exercise performance status items. It was verified that the higher mother`s LOHAS lifestyle score is, the higher children`s food behavior, daily life habits, nutrient intake, exercise performance state score are.
