Association Between Asymptomatic Malaria Infection And Pregnancy Outcome In Delta State, Nigeria, Sadiatu Sally Obi Jan 2021

Association Between Asymptomatic Malaria Infection And Pregnancy Outcome In Delta State, Nigeria, Sadiatu Sally Obi

Walden Dissertations and Doctoral Studies

Pregnant women are vulnerable due to the pregnancy-induced suppressed immunity in malaria-endemic areas. Asymptomatic malaria in pregnancy (MiP) threatens both the mother, fetus, and neonate via chronic placental malaria which impacts maternal-neonatal exchange. Some studies reported that MiP risk factors vary across locations, however, there are few studies on MiP and pregnancy outcome in Nigeria. The purpose of this study was to investigate the association between asymptomatic placental malaria infection and pregnancy outcome among parturients in Asaba, Delta State, Nigeria. This study was developed with a quantitative methodology that utilized primary and secondary healthcare data from 483 subjects aged 18–49 …


A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk Jan 2011

A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk

Walden Dissertations and Doctoral Studies

Researchers have identified inadequate sleep duration as one of the factors contributing to global obesity. The purpose of this study was to test a hypothesis deduced from a new sleep-duration-based evolutionary theory claiming that sleep extension in response to lengthening night duration in early fall evolved into a behavioral marker of an approaching winter; this adaptive trait was theorized to produce adiposity gain in White men in response to sleep extension. The hypothesis was that White Americans would show a greater increase in the age-adjusted fat mass index per unit of sleep duration compared to that of Black Americans. Data …
