The study involved parents who anonymously and voluntarily provided their children's personal data and assessed LDs, bedtime, meal timing, behavioral problems, gross motor skill development, and FMT consumption. Multiple regression analysis was used to analyze the associations between study variables. A total of 587 children were examined, with mean age <i>M</i> (<i>SD</i>) 5.5 (2.4) years, (range: 2-12 years), and 44.2% were boys. Children with LD had delayed sleep onset (<i>β</i> = 0.09; <i>R</i>² = 0.007), increased sleep latency (<i>β</i> = 0.11; <i>R</i>² = 0.014), social jetlag (<i>β</i> = 0.10; <i>R</i>² = 0.009), screen time (<i>β</i> = 0.14; <i>R</i>² = 0.022), and behavioral problems (<i>β</i> = 0.13-0.35; <i>R</i>² = 0.016-0.142); decreased gestational age at birth (<i>β</i> = -0.09; <i>R</i>² = 0.007), and delayed development of gross motor skills in the postpartum period (<i>β</i> = 0.11-0.21; <i>R</i>² = 0.012-0.064). The children's average FMT consumption was 2087.6 ± 2401.3 ng/d. Children with the highest FMT consumption had lower rates of LDs (<i>β</i> = -0.11; <i>R</i>² = 0.010), social jetlag (<i>β</i> = -0.08; <i>R</i>² = 0.007), and eating jetlag (<i>β</i> = -0.12; <i>R</i>² = 0.013); fever behavioral problems (<i>β</i> = -0.09 - -0.10; <i>R</i>² = 0.007-0.057); and less delayed eating phase (<i>β</i> = -0.11; <i>R</i>² = 0.012), and development of gross motor skills in the postpartum period (<i>β</i> = -0.10 - -0.12; <i>R</i>² = 0.009-0.014). In summary, LDs in children were associated with higher rates of circadian misalignment, sleep, behavioral, and developmental dysfunctions, and higher FMT consumption was associated with lower rates of circadian misalignment, behavioral, and developmental dysfunctions. The data obtained indicate the need for a detailed study of the state of the circadian system in preschool and primary school children with language difficulties, which will serve as a rationale for the use of chronotherapy principles for the treatment of this neurological dysfunction.</p>","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"70-84"},"PeriodicalIF":2.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142892638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed 121,276 records from dual-purpose crossbred cows across 36 farms along the western margin of Lake Maracaibo basin, Venezuela. The lunar cycle was divided into 30 periods of 0.984 days each and further categorized into four phases: 1) 1.97 days around the new moon; 2) 12.8 days during the crescent phase; 3) 1.97 days around the full moon; and 4) 12.8 days during the waning phase. Data were analyzed using a logistic regression and the general linear model in SAS, comparing proportions and means with contrast and general linear model tests, respectively. There was no association between the lunar cycle and the sex of calves. However, calvings distribution across the lunar month showed notable peaks 2 days around both the new and full moons, a pattern consistent regardless of the number of calvings or gestation lengths. In addition, significant differences were observed between the days surrounding the new (1) and full (3) moons compared to the other lunar phases (2 and 4). Moon cycle also influenced gestation length and calf birth weight.
