Research Studies On Developmental Origins Of Health And...

Early Adversity, Elevated Stress Physiology, Accelerated Sexual Maturation, and Poor Health in Females Purpose Recent research studies on developmental origins of health and disease involving adverse developmental experiences and environmental exposures early in life have shown to link adverse developmental experiences and environmental exposures early in life with stress physiology thus indicating a possibility of accelerated reproductive development and aging in females. It is predicted that cortisol and adrenarcheal become important key players during the first stage of puberty within females ages 6-8. Adrenarcheal is responsible for the secretion of dehydroepiandrosterone (DHEA) which is involved with the secretion of androgens, and†¦show more content†¦Family incomes ranged from less than $10,000 to $120,000. It is noteworthy to point out that there were no significant differences on these demographic characteristics between the 73 participating families. When these 73 mothers gave birth to their offspring researchers would begin analytical testing when the children would begin first grade. Researchers implemented a correlational experimental design that consisted of an 18 year longitudinal study recording several components that would determine how prenatal stress and other factors could affect the overall health and development of the child to be born. Because this experiment was longitudinal in nature there were very few variables that could be controlled. Never the less, none of the female participants were missing prenatal maternal depression (dependent variable), negative parenting (dependent variable), or child adrenarche data (dependent variable). Although necessary for consistent testing results 13 were missing childhood cortisol data (dependent variable); and 7 were missing mental and physical health data (dependent variable). In this experiment researchers sought out to take measurements in prenatal maternal stress, infancy maternal depression, infancy negative parenting, basal cortisol levels, adrenarche levels,Show MoreRelatedDifferences Between Nutrition Supply And Foetus1719 Words   |  7 Pagesnormal variations in the placental developmental process to the differences in nutrition supply to foetus, which fixes a few key systems, relates to developing diseases in later life. Certain variations in placentation processes, influence the nutrient delivery to foetus and develops a range of chronic disorders in the adult. However, further studies need to link the placental process to placental morphology at birth, and the nutrient flow, timing which causes disease in later life. When placenta enlargesRead MoreObesity Is Not A Disease1182 Words   |  5 Pagesresearchers have differing opinions on the origins and effects of obesity. The rapidly increasing rates of obesity are often linked to a high calori e diet and little to no physical activity. Although obesity is seen as a disease that affects a person’s weight, it actually affects a lot more than that. Obesity can affect individuals in both adolescence and adulthood, their families, and the healthcare system. From an outside viewpoint, obesity looks like a disease that careless, inactive people developRead MoreFamily Support System : Family Essay1172 Words   |  5 PagesAge-appropriate developmental tasks accomplishment The parents accomplished age-appropriate developmental tasks. They provide for family members’ needs, maintain a strong marital relationship, and promote their children school successes. Both children accomplished their physically, personally, and socially age developmental tasks appropriately. Nevertheless, grandparents are not adjusting well to their age developmental tasks regarding health and role changes. Family developmental stage This isRead MoreDiscuss The Concept Of Developmental Programming Essay2299 Words   |  10 Pagesconcept of ‘developmental programming’ and discuss why it is of increasing importance to population health. INTRODUCTION: This essay will describe the concept of developmental programming and the importance of it in population health. It will also provide recommendations on how the New Zealand health care system can incorporate the advice put forward from developmental programming into and neonatal prenatal care services. It is suggested that illnesses such as coronary heart disease, type 2 diabetesRead MoreThe Diversity Of Children With Autism Spectrum Disorder1243 Words   |  5 Pagesallowed me to firsthand witness what was so new to me, and most important to learn about the disorder. According to CDC, autism spectrum disorder is a group of developmental disabilities that can cause significant social communication and behavioral challenges (2015). Needless to say, while people diagnosed of ASD may carry these developmental incapacities, it typically does not distinguish them from other people. For this purpose, this disorder requires numerous cognitive and behavioral tests due toRead MoreChimera: Rethinking Humanity804 Words   |  3 Pagesoffspring. If we were to create an animal-Chimera the procedure would not be that difficult. According to the article perviously mentioned an embryo can e.g. get injected or under go an aggregation. Though the embryonic cells have to come from different origins. If it should be compared to a hybrid the difference is not that big but still a crucial element to separate these to creatures. A hybrid is the result of cross breading to animals. The cross breading usually happen between different but closely relatedRead MorePreventi ng Chilhood Obesity : Parenting Programme For Early Years1073 Words   |  5 Pages PUBLIC HEALTH - ASSIGNMENT 2 PREVENTING CHILHOOD OBESITY – PARENTING PROGRAMME FOR EARLY YEARS BACKGROUND Obesity, defined as ‘an excessive amount of body fat relative to body weight’ (Heyward, 2010, p.232) has reached global epidemic proportions and it is the fifth leading risk for global deaths with 2.8 million adults dying every year (World Health Organization, 2013).
