Adolescence is a key period for problematic internet use (PIU) and disordered eating (DE), with prior studies linking them, but the role of diet quality unclear.
This study aimed to investigate the relationships between PIU, diet quality, and DE in adolescents using mediator and network analyses, with a specific focus on the mediating role of diet quality.
A cross-sectional study was conducted with 647 high-school students in Erzurum, Turkey. Data were collected through validated instruments, including the Young Internet Addiction Test, Social Media Addiction Scale, KIDMED Mediterranean Diet Quality Index, and Eating Attitudes Test (EAT-26). Statistical analyses included mediation modeling and network analysis (NA).
The prevalence of DE risk was 18.2%, while 27% of participants met the criteria for social media addiction. Additionally, 3.6% were classified as at potential risk for internet addiction. In addition to PIU and social media addiction, higher maternal education levels were also significantly associated with greater DE risk (p < 0.05). Mediation analysis showed that problematic internet use was linked to lower adherence to the Mediterranean diet (β = -0.12, p = 0.002), which was associated with higher DE risk (β = 0.15, p < 0.001). The indirect effect was significant (β = -0.02, p = 0.016), supporting partial mediation. NA identified internet addiction as the central node, linking DE risk, social media disorder, and diet quality.
Internet addiction is linked to increased DE risk, mediated by diet quality, highlighting the need to address it in adolescent interventions. Longitudinal studies are needed.

青少年时期是网络使用问题（PIU）和饮食失调（DE）的关键阶段，先前的研究已将二者联系起来，但饮食质量的作用尚不清楚。
本研究旨在通过中介分析和网络分析，探讨青少年PIU、饮食质量和DE之间的关系，特别关注饮食质量的中介作用。
对土耳其埃尔祖鲁姆的647名高中生进行了一项横断面研究。通过经过验证的工具收集数据，包括青少年网络成瘾测试、社交媒体成瘾量表、KIDMED地中海饮食质量指数和饮食态度测试（EAT-26）。统计分析包括中介模型和网络分析（NA）。
DE风险的患病率为18.2%，而27%的参与者符合社交媒体成瘾标准。此外，3.6%被归类为有网络成瘾的潜在风险。除了PIU和社交媒体成瘾外，母亲教育水平较高也与更高的DE风险显著相关（p < 0.05）。中介分析表明，网络使用问题与较低的地中海饮食依从性相关（β = -0.12，p = 0.002），而这又与较高的DE风险相关（β = 0.15，p < 0.001）。间接效应显著（β = -0.02，p = 0.016），支持部分中介作用。NA将网络成瘾确定为中心节点，连接DE风险、社交媒体紊乱和饮食质量。
网络成瘾与DE风险增加有关，由饮食质量介导，突出了在青少年干预中解决这一问题的必要性。需要进行纵向研究。
