In recent years, the role of magnesium in sleep disorders has garnered considerable attention. Magnesium not only reduces the excitability of the nervous system and alters muscle relaxation but also regulates cellular biological clocks, energy balance, and circadian rhythms, playing a crucial role in sleep regulation. Magnesium deficiency not only shortens the effective sleep duration but also impairs sleep quality, leading to various specific sleep disorders. Additionally, magnesium supplements can improve sleep parameters in a variety of sleep-related diseases, especially those associated with the occurrence and development of sleep disorders. Therefore, a more in-depth understanding of the impact of magnesium on sleep disorders may reveal new therapeutic targets for sleep-related diseases.

{"title":"Sleep-Disordered Breathing as a Mediator Between Premature Birth and Behavior Problems in School-Aged Children: A Cross-Sectional Study of 6-10 Year Olds in Shanghai, China.","authors":"Yuli Hu, Siqiong Jiang, Shiyin Yang, Chunsheng Wang, Jianyin Zou, Jian Guan, Yupu Liu, Qunfeng Lu","doi":"10.2147/NSS.S539617","DOIUrl":"10.2147/NSS.S539617","url":null,"abstract":"<p><strong>Background: </strong>Premature birth poses a major challenge in global obstetric clinical practice. The relationship between preterm infants and behavioral problems in school-aged children remains debatable, and the mediating role of sleep-disordered breathing (SDB) in this connection has not been investigated. This study aimed to address these gaps through a large-scale cross-sectional survey.</p><p><strong>Methods: </strong>We recruited 18,138 children aged 6-10 from schools. Data on demographics, prematurity, SDB, and childhood behavioral problems were collected. The Paediatric Sleep Questionnaire (PSQ), a validated screening tool, assessed SDB symptoms, and the Conners' Parent Rating Scale (CPRS) evaluated behavioral problems. Path analysis with bootstrap methods was used for statistical analysis.</p><p><strong>Results: </strong>Among 18,138 participants, 8% (n = 1,450) were premature. After adjusting for age, gender, BMI <i>z-</i>score, maternal age, and maternal education level, prematurity showed a positive association with total PSQ score (B = 0.411, p < 0.01). Higher total PSQ scores were significantly associated with all six CPRS dimensions (all p < 0.05). While prematurity was not directly associated with Conduct, Psychosomatic, Impulsive-hyperactive, or Hyperactivity scores in CPRS (all p > 0.05), it demonstrated significant associations with Learning problems (β = 0.063, p = 0.005) and Anxiety scores (β = 0.076, p = 0.003). Mediation analysis showed PSQ accounted for a large proportion of associations between prematurity and Conduct, Psychosomatic, Impulsive - hyperactive, and Hyperactivity problems (95% Bootstrap CI excluded 0).</p><p><strong>Conclusion: </strong>Premature infants may exhibit behavioral problems significantly associated with SDB, though our cross-sectional design precludes causal inference and parent-reported SDB severity may bias true associations. Future studies should utilize longitudinal cohorts to explore whether SDB is involved in the relationship between prematurity and behavioral problems (eg, anxiety). Additionally, they should conduct pilot randomized controlled trials of SDB interventions in preterm infants to assess neurodevelopmental benefits. Final conclusions require subsequent causal validation.</p>","PeriodicalId":18896,"journal":{"name":"Nature and Science of Sleep","volume":"17 ","pages":"2599-2610"},"PeriodicalIF":3.4,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12515976/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145292926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
