CRF is considered a strong predictor of health outcomes. However, cardiorespiratory fitness levels of children and adolescents are declining.Aims: (1) To analyse the cardiorespiratory fitness levels of children and adolescents in China, focusing on maximum oxygen uptake (VO2max), maximum heart rate (HRmax), peak oxygen uptake (Peak VO2) and 20-metre shuttle run test (20 m-SRT). (2) To provide baseline data, with the goal of supporting the development of sports programs, intervention strategies, and public health decision-making.Subjects and methods: A meta-analysis was conducted using 30 studies selected from five databases.Results: The average performance on 20 m-SRT for Chinese children and adolescents was 34.67 laps, with a VO2max of 46.47 ml/kg/min, HRmax of 195.02 bpm, and Peak VO2 of 48.58 ml/kg/min. Boys outperformed girls in VO2max, 20 m-SRT, and HRmax, although the differences in HRmax and Peak VO2 were not statistically significant. Tibetan children showed better performance than Han children in three indicators with no significant differences found.Conclusion: Cardiorespiratory fitness in Chinese children and adolescents is within a healthy range but not optimal. Boys generally perform better than girls, and Tibetan children outperform Han children.","PeriodicalId":50765,"journal":{"name":"Annals of Human Biology","volume":"52 1","pages":"2459141"},"PeriodicalIF":1.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143484578","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}

Evidence suggests that high temperatures and heat stress influence breastfeeding behaviour and may lead to suboptimal infant and young child nutrition.Aim: Few studies have quantified the relationship between ambient heat and breastfeeding. Here we evaluate associations between wet-bulb temperature and daily breastfeeding patterns in a rural community in Bangladesh.Subjects and methods: We used 23 months of daily time-diary data from 68 maternal-child dyads and regional wet-bulb temperatures to test the hypothesis that increased heat and humidity negatively influence breastfeeding outcomes among Shodagor fisher-traders.Results: We found that higher wet-bulb temperatures predicted reduced daily breastfeeding time allocation, particularly among fishers, and drove shifts towards increased night-time and decreased mid/late morning feeding. Maternal occupation and the interaction of child age with heat strongly influenced diurnal breastfeeding patterns.Conclusion: These results highlight an important role of maternal work on infants' vulnerability to environmental stress. Dyads' ability to behaviourally compensate for extreme heat may be constrained by extended heatwaves, humidity, and economic circumstances, suggesting that climate change will likely exacerbate heat-related risks to global child health going forward.","PeriodicalId":50765,"journal":{"name":"Annals of Human Biology","volume":"52 1","pages":"2461709"},"PeriodicalIF":1.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143484580","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 protection is likely multifactorial, with roles for both milk immune factors and nutrients, particularly under elevated nutritional and disease stress.Aim: This study evaluated several milk nutrients/immune factors to assess associations with infant infectious disease during a severe drought.Subjects and methods: The study analysed morbidity recall data from Kenyan mother-infant dyads surveyed during a historic drought (n 84). Predictors of interest in logistic regression models of infant infections included milk sIgA, lactoferrin, retinol, folate receptor-α, fat, protein, and lactose. Adjustment variables included dyadic demographic characteristics and maternal infection. Akaike Information Criterion guided model fit assessment. Interactions between variables were allowed in the best-fit model.Results: In the best-fit model, lactose was inversely (OR 0.93; 90% CI 0.89, 0.97), and maternal infection was positively (OR 2.80; 90% CI 1.04, 7.52) associated with infant infection. Milk immune factors (sIgA, lactoferrin) were not included in the final models.Conclusion: Mothers' milk may protect infants against infection through a broad range of immune and nutrient components. In the context of severe drought with heightened nutritional and disease stress, lactose may protect against infection or decrease in the presence of an infection.","PeriodicalId":50765,"journal":{"name":"Annals of Human Biology","volume":"52 1","pages":"2455703"},"PeriodicalIF":1.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400520","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}

The most closely related lineage of this paternal lineage is mainly distributed in Tungusic-, Mongolic-, and Turkic-speaking populations.Aim: To investigate the formation process of this unique distribution state.Subjects and methods: In total, 36 sequences of haplogroup C2a-M48-F8472 were analysed to generate a revised phylogenetic tree with age estimation and to explore the geographic distribution pattern.Results: The results suggested that northern China is likely the diffusion centre of this paternal haplogroup. This lineage is concentrated in the Liu clan () of Han populations and may have originated in the Tuge tribe () of Xiongnu populations. The initial expansion (∼2,600 years ago) and the second phase of expansion (∼1,570 years ago) of haplogroup C2a-M48-F8472 coincide with the earlier appearance and later disappearance of the Tuge tribe. As a sub-clade of M48, the history of F8472 suggested that ancient peoples related to Tungusic-speaking populations were intricately connected with the demographic history of populations in the Mongolian Plateau.Conclusion: The appearance of this paternal line in the Han population is helpful for understanding the mixed history of ancient and modern people in the Mongolian Plateau and Central China.","PeriodicalId":50765,"journal":{"name":"Annals of Human Biology","volume":"51 1","pages":"2398610"},"PeriodicalIF":1.2,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142570356","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}
