Early postnatal experience can modify maternal-infant interactions and thus modulate maternal physiological and behavioral adaptations induced by gestational undernutrition. Although species differences must be considered, this early postnatal window in rodents approximates human early infancy. We tested whether neonatal handling, an early-life manipulation that increases maternal care, modifies the effects of maternal protein restriction during gestation and early lactation on maternal behavior, milk composition, and lactogenic hormones. Wistar rat dams received a control (22% protein) or low-protein (8%, isoenergetic) diet throughout gestation and the first week of lactation. Litters were assigned to either neonatal handling (10 min/day, postnatal days 1-6) or undisturbed rearing with their dams. We measured maternal caloric intake, gestational weight gain, pup growth, maternal licking and grooming, milk macronutrients on postnatal day 6, and maternal serum prolactin, corticosterone, and insulin. Thirty-seven dams were included (8-10 per treatment group), and litter size did not differ between groups. Maternal low-protein diet significantly reduced pup body weight and milk protein content, while neonatal handling significantly increased maternal licking/grooming in low-protein dams and reversed the reduction in milk protein concentration. Additionally, neonatal handling decreased insulin levels in control dams, but had no effect in low protein dams, while prolactin and corticosterone were not altered between groups. Together, these findings indicate that early postnatal experience can modify a maternal phenotype induced by gestational undernutrition, including maternal care and lactational composition, with a metabolic signature involving insulin.</p>","PeriodicalId":49167,"journal":{"name":"Journal of Developmental Origins of Health and Disease","volume":"17 ","pages":"e53"},"PeriodicalIF":1.6,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149197317","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}

Although most infants achieve stable physiological adaptation, transient fluctuations in oxygen saturation and respiratory control are frequently observed during early neonatal life and are generally considered benign once stability is restored. However, the physiological implications of such transient instability have rarely been systematically examined.This article proposes the concept of subclinical neonatal hypoxic stress (SNHS) as a theoretical framework describing mild and transient oxygen-related physiological stress that may occur during neonatal transition without producing overt manifestations of clinically significant hypoxia or hypoxic injury. SNHS is conceptualized as a hypothesized subclinical physiological vulnerability state within the continuum of neonatal adaptation, distinct from both ordinary physiological variability and clinically significant hypoxic conditions. Episodes potentially consistent with SNHS may include brief transitional instability that resolves rapidly, sometimes following minimal supportive measures, after which infants are considered clinically normal.The paper outlines the physiological basis of neonatal oxygen variability, differentiates SNHS from established hypoxic disorders, and proposes empirically testable approaches for investigating this potential transitional state within early-life physiology. If validated, the SNHS framework could support more precise characterization of transient oxygen instability during neonatal transition and inform future monitoring strategies aimed at distinguishing benign physiological variability from potentially meaningful subclinical physiological stress.</p>","PeriodicalId":49167,"journal":{"name":"Journal of Developmental Origins of Health and Disease","volume":"17 ","pages":"e52"},"PeriodicalIF":1.6,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149197460","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}

This conceptual paper synthesises the DOHaD paradigm, First 1000 Days approaches, common risk factor theory, and Pacific relational worldviews to propose a Pacific-centred framework that explicitly integrates oral health. Using the Cook Islands as a regional exemplar, the paper demonstrates how oral health can be aligned with existing maternal and child health, nutrition, and NCD policy priorities. The proposed framework reframes ECC as both a biologically embedded developmental outcome and an early indicator of broader NCD risk trajectories. It highlights the interconnected influence of biological, family, community, health system, and policy environments on oral health across the life course.
