Health before conception, and periconceptional nutritional environments, contribute to conditioning of later-life health and disease. Health behaviors developed during adolescence continue into adulthood. Thus, even when the gap between pregnancy and adolescence is substantial, behaviors developed during adolescence influence later-life non-communicable disease (NCD) vulnerability in offspring. Consequently, adolescence is an important life phase where development of positive health behaviors can contribute to disruption of transgenerational cycles of NCD risk. Schooling is a core activity during adolescence. Modern curricula focus on development of capabilities associated with critical, engaged citizenship, empowering learning that supports action-based engagement in complex issues. Contexts relevant to adolescents and their communities, such as the NCD epidemic, are used to facilitate learning. Thus, engaging the education sector as participants in the work of the Developmental Origins of Health and Disease community offers an important strategy to capture the potential of adolescence as a life stage for transgenerational primary prevention of obesity and NCD risk.

Intrauterine growth restriction (IUGR) and fetal growth restriction (FGR) are pregnancy complications associated with morbidity in later life. Despite a growing body of evidence from current research on developmental origins of health and disease (DOHaD), little information is currently provided to parents on long-term metabolic, cardiovascular and neurologic consequences. As parents strongly rely on internet-based health-related information, we examined the quality of information on IUGR/FGR sequelae and DOHaD in webpages used by laypersons. Simulating non-clinicians experience, we entered the terms ‘IUGR consequences’ and ‘FGR consequences’ into Google and Yahoo search engines. The quality of the top search-hits was analyzed with regard to the certification through the Health On the Net Foundation (HON), currentness of cited references, while reliability of information and DOHaD-related consequences were assessed via the DISCERN Plus score (DPS). Overall the citation status was not up-to-date and only a few websites were HON-certified. The results of our analysis showed a dichotomy between the growing body of evidence regarding IUGR/FGR-related sequelae and lack of current guidelines, leaving parents without clear directions. Furthermore, detailed information on the concept of DOHaD is not provided. These findings emphasize the responsibility of the individual physician for providing advice on IUGR/FGR-related sequelae, monitoring and follow-up.

At STIAS, the ‘Health in Transition’ theme includes a programme to address the epidemic rise in the incidence of non-communicable diseases (NCDs) such as Type 2 diabetes, hypertension, obesity, coronary heart disease and stroke in Africa. The aim is to advance awareness, research capacity and knowledge translation of science related to the Developmental Origins of Health and Disease (DOHaD) as a means of preventing NCDs in future generations. Application of DOHaD science is a promising avenue for prevention, as this field is identifying how health and nutrition from conception through the first 1 000 days of life can dramatically impact a developing individual’s future life course, and specifically predicate whether or not they are programmed in infancy to develop NCDs in later life. Prevention of NCDs is an essential strategy as, if unchecked, the burden of caring for a growing and ageing population with these diseases threatens to consume entire health budgets, as well as negatively impact the quality of life of millions. Africa in particular needs specific, focussed endeavors to realize the maximal preventive potential of DOHaD science, and a means of generating governmental and public awareness about the links between health in infancy and disease in adult life. This volume summarizes the expertise and experience of a leading group of international scientists led by Abdallah Daar brought together at STIAS as part of the ‘Health in Transition’ programme.

Vitamin D is an essential nutrient that is metabolized in the body to generate an active metabolite (1,25(OH)2D) with hormone-like activity and highly diverse roles in cellular function. Vitamin D deficiency (VDD) is a prevalent but easily preventable nutritional disturbance. Emerging evidence demonstrates the importance of sufficient vitamin D concentrations during fetal life with deficiencies leading to long-term effects into adulthood. Here, we provide a detailed review and perspective of evidence for the role of maternal VDD in offspring long-term health, particularly as it relates to developmental origins of health and disease (DOHaD). We focus on the roles in neurobehavioral and cardiometabolic disorders in humans and highlight recent findings from zebrafish and rodent models that probe potential mechanisms linking early life VDD to later life health outcomes. Moreover, we explore evidence implicating epigenetic mechanisms as a mediator of this link. Gaps in our current understanding of how maternal VDD might result in deleterious offspring outcomes later in life are also addressed.

AbstractEpigenetic changes represent a potential mechanism underlying associations of early-life exposures and later life health outcomes. Population-based cohort studies starting in early life are an attractive framework to study the role of such changes. DNA methylation is the most studied epigenetic mechanism in population research. We discuss the application of DNA methylation in early-life population studies, some recent findings, key challenges and recommendations for future research. Studies into DNA methylation within the Developmental Origins of Health and Disease framework generally either explore associations between prenatal exposures and offspring DNA methylation or associations between offspring DNA methylation in early life and later health outcomes. Only a few studies to date have integrated prospective exposure, epigenetic and phenotypic data in order to explicitly test the role of DNA methylation as a potential biological mediator of environmental effects on health outcomes. Population epigenetics is an emerging field which has challenges in terms of methodology and interpretation of the data. Key challenges include tissue specificity, cell type adjustment, issues of power and comparability of findings, genetic influences, and exploring causality and functional consequences. Ongoing studies are working on addressing these issues. Large collaborative efforts of prospective cohorts are emerging, with clear benefits in terms of optimizing power and use of resources, and in advancing methodology. In the future, multidisciplinary approaches, within and beyond longitudinal birth and preconception cohorts will advance this complex, but highly promising, the field of research.

AbstractEvidence supporting the Developmental Origins of Health and Disease (DOHaD) hypothesis indicates that improving early life environments can reduce non-communicable disease risks and improve health over the lifecourse. A widespread understanding of this evidence may help to reshape structures, guidelines and individual behaviors to better the developmental conditions for the next generations. Yet, few efforts have yet been made to translate the DOHaD concept beyond the research community. To understand why, and to identify priorities for DOHaD Knowledge Translation (KT) programs, we review here a portion of published descriptions of DOHaD KT efforts and critiques thereof. We focus on KT targeting people equipped to apply DOHaD knowledge to their everyday home or work lives. We identified 17 reports of direct-to-public DOHaD KT that met our inclusion criteria. Relevant KT programs have been or are being initiated in nine countries, most focusing on secondary school students or care-workers-in-training; few target parents-to-be. Early indicators suggest that such programs can empower participants. Main critiques of DOHaD KT suggest it may overburden mothers with responsibility for children’s health and health environments, minimizing the roles of other people and institutions. Simultaneously, though, many mothers-to-be seek reliable guidance on prenatal health and nutrition, and would likely benefit from engagement with DOHaD KT. We thus recommend emphasizing solidarity, and bringing together people likely to one day become parents (youth), people planning pregnancies, expecting couples, care workers and policymakers into empowering conversation about DOHaD and about the importance and complexity of early life environments.

Developmental Origins Of Disease

Human epidemiological studies have indicated that the risk of developing non-communicable diseases in later life may be related to exposures during the developmental period. Developmental life is a vulnerable period of the lifespan during which adverse environmental factors have the potential to disturb the processes of cell proliferation and differentiation or to alter patterns of epigenetic remodelling. Animal models have been instrumental in demonstrating the biological plausibility of the associations observed in human populations, providing proof of principle to the theory of the developmental origins of health and disease (DOHaD). A variety of large- and small-animal models have made important contributions to the field, providing strong evidence of a causal relationship between early-life exposures and metabolic risk factors in later life. Studies of animal models are continuing to contribute to improving the understanding of the mechanisms of the developmental origins of disease. All models have their advantages and disadvantages, and the model that is most appropriate for any particular study is hypotheses dependent. The present review aims to briefly summarise the contributions that animal models have made to the DOHaD field, before reviewing the strengths and weaknesses of these animal models. It is proposed that the integration of evidence from a variety of different models is required for the advancement of understanding within the field.

And Function

Epidemiological data indicate that developmental programming of various non-communicable diseases (NCDs) occurs as a consequence of altered maternal metabolic and physiological status due to a number of environmental insults during pregnancy. Sex-specific differences have also been reported in most NCDs. Evidence suggests that beginning from conception, the maternal and neonatal metabolic environment, including hormones, contributes to sex-specific placental development. The placenta then regulates the sex-specific differences in NCDs via the epigenetic mechanisms that are further affected by hormones. Male and female embryos have been reported to exhibit sex-specific transcriptional regulation, and it is suggested that their development can be considered as separate processes beginning from conception. This review summarises various animal and human studies examining sex-specific differences in NCDs due to differential placental epigenetic developmental programming. An overview of possible mechanisms underlying this is also discussed. Further, the review describes sex-specific changes in the structure and function of the placenta in pregnancies complicated by fetal growth restriction, pre-eclampsia and preterm birth. Thus, because sex-specific differences are associated with fetal outcome and survival, future studies need to take into consideration the sex of the fetus while explaining the concept of the developmental origins of health and disease.
