Relationships Among Maternal Epstein–Barr Virus Antibodies, Covid ‐19, and Stress in Mothers up to 1‐Year Postpartum
OBJECTIVES: Both psychosocial stress and current infection can increase the likelihood of reactivation of latent Epstein-Barr virus (EBV). Pregnancy and infection with SARS-CoV-2 can be stressful and modulate immune function. However, it is unknown how SARS-CoV-2 infection and stress further interact among postpartum women to affect EBV antigen and antibody expression. METHODS: We examined associations among COVID-19 diagnosis, self-reported stre…
Postpartum Maternal Stress is Unrelated to the Infant Fecal Microbiome, but is Associated With the Human Milk Microbiome in Exclusively Breastfeeding Mother‐Infant Dyads
Objectives This study aimed to evaluate whether postpartum maternal stress is associated with infant gastrointestinal microbiome composition and diversity, and whether this relationship may be mediated by maternal caregiving and breastfeeding behaviors and human milk microbiome (HMM) composition. Methods Infant fecal and human milk samples were collected from 51 exclusively breastfeeding mother‐infant dyads in the Pacific Northwest between 1 and …
Human milk immune factors, maternal nutritional status, and infant sex
OBJECTIVES: Breastfeeding is an energetically costly and intense form of human parental investment, providing sole-source nutrition in early infancy and bioactive components, including immune factors. Given the energetic cost of lactation, milk factors may be subject to tradeoffs, and variation in concentrations have been explored utilizing the Trivers-Willard hypothesis. As human milk immune factors are critical to developing immune system and p…
DHEAS and nutritional status among Sidama, Ngandu, and Aka children
OBJECTIVE: Adrenarche, the biological event marked by rising production of dehydroepiandrosterone and its sulfate (DHEAS), may represent a sensitive period in child development, with important implications for adolescence and beyond. Nutritional status, particularly BMI and/or adiposity, has long been hypothesized as a factor in DHEAS production but findings are inconsistent, and few studies have examined this among non-industrialized societies. …
Life history and socioecology of infancy
OBJECTIVES: Evolution of human maternal investment strategies is hypothesized to be tied to biological constraints and environmental cues. It is likely, however, that the socioecological context in which mothers' decisions are made is equally important. Yet, a lack of studies examining maternal investment from a cross-cultural, holistic approach has hindered our ability to investigate the evolution of maternal investment strategies. Here, we take…
Household composition and the infant fecal microbiome
OBJECTIVES: Establishment and development of the infant gastrointestinal microbiome (GIM) varies cross-culturally and is thought to be influenced by factors such as gestational age, birth mode, diet, and antibiotic exposure. However, there is little data as to how the composition of infants' households may play a role, particularly from a cross-cultural perspective. Here, we examined relationships between infant fecal microbiome (IFM) diversity/c…
Social networks, cooperative breeding, and the human milk microbiome
OBJECTIVES: We present the first available data on the human milk microbiome (HMM) from small-scale societies (hunter-gatherers and horticulturalists in the Central African Republic [CAR]) and explore relationships among subsistence type and seasonality on HMM diversity and composition. Additionally, as humans are cooperative breeders and, throughout our evolutionary history and today, we rear offspring within social networks, we examine associat…
DHEAS patterning across childhood in three sub‐Saharan populations
OBJECTIVES: Hormones have many roles in human ontogeny, including the timing of life history 'switch points' across development. Limited hormonal data exist from non-Western children, leaving a significant gap in our understanding of the diversity of life history patterning. This cross-sectional study examines dehydroepiandrosterone sulfate (DHEAS) production in relation to age, sex, ethnicity, and cortisol concentrations, as well as average age …
Sibling effects on nutritional status
OBJECTIVES: Examination of sibling effects on nutritional status is complicated by siblings being both alloparents and resource competitors, as well as the extensive changes children undergo across development. To evaluate sibling nutritional effects with consideration of these opposing roles, we use an evolutionary framework rooted in human ontogeny and cooperative breeding. METHODS: Anthropometric data were collected from 113 Ngandu horticultur…
Cooperative breeding and Aka children's nutritional status
Research suggests that nonmaternal caregivers (allomothers) offer essential assistance through caregiving and provisioning, helping to support lengthy child development. Here, we examine the role of allomothers and the broader social and sharing network on Aka forager children's anthropometrics. We hypothesize that nonmaternal investors strategically target their assistance when it is most needed and when it will have the greatest effect. We eval…
