The prevalence of being underweight amongst adolescent girls has increased in Indonesia. One of the factors hat affects weight is parental characteristics. The study aimed to describe and analyze the association between parental characteristics and the nutritional status of adolescent girls. A cross sectional study was conducted to collect data characteristics of girls and their parents related to nutrition. 112 girls in MTSN 2 Padang Pariaman were respondents selected through a proportional stratified random sampling technique. The nutritional status of adolescent girls was determined through weight and height measurement; after that, it was compared with age. Data was collected using a standardized questionnaire, and then the data was analyzed using a computer program. Chi-square tests were used to analyze bivariate with a significant level determined if p-value was less than 0.05. The result showed that about 50% of girls were underweight. The percentage of underweight girls was higher for girl’s whose father’s were less educated and mother’s highly educated, but itwas not statistically significant. There was an association between economic status and nutritional status (p-value<0.05), and other factors tended to be associated with underweight status among adolescent girls. Health and nutrition education is needed to increase the knowledge of adolescent girls about nutritious food and nutritional status. Collaboration activities of health institutions with health education institutions could be done routinely in schools to prevent and combat malnutrition problems, specifically among adolescent girls.
