Its impact on Quality of life (QoL) in adolescents/adults with TS have been studied using generic QoL questionnaires. Short stature specific QoL questionnaires have not been used to study the impact of short stature and GH therapy in TS in previous studies. Methods: In this cross-sectional study, we aimed to evaluate QoL and the association between GH therapy and height on QoL of adolescents using the short stature specific questionnaire -Quality of Life in Short Stature Youth (QoLISSY). QoLISSY was designed specifically to assess QoL in short stature children with scales for both parents and children which assesses 3 core QOL dimensions: physical, social, emotional and 3 predictors of quality of life: Coping, Beliefs and Treatment (GH therapy). It has not been previously used in TS. Results: Of the 41 eligible patients, 37 patients were enrolled in the study. The mean age of our cohort was 16.3 ±1.3 years and the average final adult height was 145.03 ± 7.3 cm. About 70% of the patients received GH therapy and 80% received estrogen therapy. Compared to the reference short stature mean values, our TS cohort had comparable scores in all QoL subscales and total scores in both parent and patient reports apart from the parental report treatment subscale which was significantly lower than their respective reference short stature means [Mean ± SD: 47.43±27.13 vs 58.82±16.75; p=0.03]. Girls with height >-3SD had significantly lower score in the coping subscale, compared to the <-2SD height group [Mean ± SD: 42.14 ± 19.04 vs 62.25 ± 16.60; p= 0.024; multivariate analysis: p=0.012. In the parent report, the social subscale was significantly lower in the > -3SD height group compared to the <-2SD height group [Mean ± SD: 57.59 ± 22.25 vs 80.94 ± 11.26; p=0.022; multivariate analysis: p=0.024]. There was no statistically significant difference in the QOL between the GH vs no GH groups. Conclusion: We conclude that the QoL in girls with TS was comparable to the reference short stature population. GH therapy did not improve the QoL in girls with TS in our cohort. Height does not appear correlate with the overall QoL in girls with TS though they have some coping and social difficulties. We recommend psychological counseling and support for girls with TS especially to address their coping and social difficulties. Presentation: Friday, June 16, 2023
