台灣地區兒童特殊靜態活動、高熱量飲食攝取及身體質量指數之分析：2001年NHIS之結果

Objectives: The purpose of this study was to understand the current status of TV watching, computer playing, reading, intakes of fast food, snacks, and sweetened drinks, and the factors associated with overweight children aged between 7 and 12 in Taiwan. Methods: This study utilized the data from the National Health Interview Survey (NHIS) in Taiwan collected in year 2001. Items in questionnaires for children under 12 years old were used. They were also linked to questionnaires for people older than 12 years in the same household. Items used in this study were demographic characteristics, time spent watching TV, playing computer games and reading books, and the frequencies of having fast food, snacks, and sweetened drinks during the week. The percentage increased to 60-70% in weekends. Time spent watching TV differed in families with different income levels. Mainly, children in families with lower income levels tended to spend more time watching TV than those with higher incomes. Time spent playing computer games increased as age increased. With respect to the intakes of fast food, about 30% of children ate fast food more than one in a week. About 70% of children drank sweetened drinks more than once a week. When combining time spent watching TV and playing computer games, intakes of fast food and sweetened drinks, and the percentage of family members overweight in a logistic model, we found over 50% of family members on the overweight children could be due to genetic effects. However, we could not ignore the effect of life styles in the same family. Intervention program for overweight children should target the family life styles.
