This stage features exploration of lifestyle behaviours, facilitated by greater autonomy. Emerging adults with Type 1 Diabetes Mellitus (T1DM) face challenges balancing self-care with social, academic, and professional demands, often achieving suboptimal glycemic control. Nutrition and sleep are crucial in T1DM management, influencing glycemic outcomes and Health-Related Quality of Life (HRQoL). Addressing these behaviours is critical given the difficulties maintaining target glucose levels in this group. Objective: to evaluate the influence of type 1 diabetes mellitus on the health-related quality of life in emerging adults with this condition in Andalusia. Methodology: study included a systematic review and a cross-sectional study. The systematic qualitative review, registered in PROSPERO (CRD42021240637), examined qualitative studies on lifestyle behaviours in individuals with T1DM aged 18–31, published between 2010 and 2021. Data were synthesised from 34 studies across eight databases, using PRISMA 2020 guidelines and Joanna Briggs Institute tools for quality assessment. The cross-sectional study (2020–2022) involved 362 participants (quantitative sample) and 73 participants (qualitative sample) in Andalusia. Recruitment was conducted via diabetes associations, social media, and public outreach. Data collection included semi-structured interviews and an online form comprising sociodemographic and clinical data, and validated questionnaires (Mediterranean Diet adherence, Oviedo Sleep Questionnaire, and ViDa1). Quantitative analysis used descriptive and inferential statistics, with regression models adjusted for Type I errors. Results: the systematic review identified eight themes, including emotions, perceptions, stigma, social relations, nutrition, self-care, and sleep, reflecting the complex experiences of emerging adults with T1DM. Findings highlighted the impact of academic and professional adjustments, were competing demands often displaced diabetes management. From the qualitative sample (71 participants, median age 20, 57.7% women), 65.8% reported HbA1c >7%. 62% of participants (44 out of 71) did not acknowledge the relationship between diabetes and sleep quality, even though 40.9% of them (18 out of 44) reported suffering three or more overnight glycemic alterations per week. The quantitative sample (362 participants, mean age 22.8, 67.4% women) revealed 52.1% with HbA1c >7%. HRQoL was generally good but varied by predictors (Interference with life: age and biological sex, with women reporting more interference; Self-care: HbA1c; Well-being: biological sex, HbA1c, and BMI; Concern about the disease: biological sex and HbA1c). Insomnia was the main predictor across most HRQoL dimensions. Disaggregated biological sex analysis showed insomnia impacted female more, while hypersomnolence and sleep satisfaction affected male. Notably, 47.5% met criteria for insomnia, and 6.9% for hypersomnolence (DSM-5 criteria). Conclusions: emerging adults with T1DM often delay self-care due to lifestyle demands, necessitating tailored health strategies. High rates of insomnia symptoms highlight the need for systematic sleep assessments and interventions. Despite concerns about glycemic control and complications, HRQoL remains generally good. Biological sex specific differences underline the importance of conducting regular sleep and quality of life assessments from a gender perspective in this age group.application/pdf354 p.spaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccess
