While the risk of developing obesity in the later years is higher in children with high birth weight. Physical and psychological conditions can affect the quality of life of adolescents.Objective: To analyze the association between birth weight and quality of life in early and middle adolescents.Methods: This cross-sectional study involved 120 students aged 13-16 years in Semarang City in which a consecutive sampling method was used. The study was conducted in August 2020. Research subjects need to fill up the PedsQL, PAQ, birth history, and socio-economic questionnaires. Statistical analyses used were Chi-square and logistic regression tests.Results: Birth weight was significantly associated with quality of life (p=0.002). A history of abnormal birth weight increases the risk of experiencing poor quality of life as a teenager (p=0.002; OR=3.987). Low birth weight was associated with decreased physical function (p=0.001), whereas high birth weight was associated with reduced social and school functioning (p=0.013; 0.032). Gender was significantly associated with quality of life (p=0.016). Girls tend to have a higher risk of experiencing poor quality of life (p=0.021; OR=4.021).Conclusion: Birth weight has a significant association with quality of life in early and middle adolescents. Adolescents with a history of LBW or HBW were more likely to experience decreased quality of life than adolescents with a history of NBW.Keywords: Adolescence, Birth weight, Quality of Life.]]>
