Filter by:Maternal undernutrition is a global public health problem with far-reaching effects for both mothers and infants. Poor maternal nutrition negatively affects fetal growth and development. Both micro and macro-nutrients are required for the physiological changes and increased metabolic demands during pregnancy, including fetal growth and development. Women in Bangladesh have poor diets and are struggling to meet their nutrient requirements, especially during pregnancy and lactation when requirements are higher. Maternal undernutrition during pregnancy is associated with a range of adverse birth outcomes, including stillbirths, preterm births, low birthweight, and small-for-gestational-age (SGA) neonates, all of which remain unacceptably high in Bangladesh. Social protection provides a promising platform on which to leverage improvements in nutrition at scale, but current evidence on the impacts of social protection on birth outcomes is limited: few studies have been conducted and some of these studies suffer from methodological limitations. The planned study will contribute to filling this knowledge gap. An additional motivation for the study is provided by the recent WHO 2016 Antenatal Care Guidelines. The guidelines call for studies on the effectiveness of alternatives to providing energy and protein supplements to pregnant women (which is recommended in undernourished populations). Studying the effectiveness of providing combinations of food and cash will help build this evidence base. A third reason to conduct the study is that both food transfers and cash transfers are commonly used policy instruments in Bangladesh, and the choice of intervention components to scale up in the CBP will be guided by the findings from this pilot study. The study findings will thus be highly policy relevant. A three-arm cluster-randomized, non-masked, community-based, longitudinal trial will be used. Groups of pregnant women will be randomly assigned to one of three study arms providing different combinations of cash and food transfers.
The project is designed as a randomized controlled intervention trial in which 60 young trained (n = 30) (Population A) and recreationally active (n = 30) women (Population B) with regular menstruation are divided into four groups. Population A will receive a low-calorie diet + exercise or an energy balanced diet + exercise over 10 days. Population B will receive a low-calorie diet without exercise, or an energy balanced diet over 10 days. The participants are matched in pairs based on training history and randomized. Before the diet period, the groups will undergo a 6-day control period, during which all participants must take an energy-balanced diet (± training). After the 10 days of the diet intervention period, the groups will receive an energy-balanced diet for 2 days. Before, during, and after the trial period, participants will perform performance tests. In addition, 3 muscle biopsies, 2 adipose biopsies, blood samples, urine samples will be taken during the period, as well as resting metabolic rate, electrocardiogram, flow-mediated vasodilation, and body composition over the trial period. Muscle protein synthesis rate will be measured over the period using stable isotope technique, which includes ingestion of heavy water (D2O) and collection of saliva samples daily (days 0 to 16). The primary measurement parameter is changes in muscle protein synthesis rate.
The purpose of this study is to determine whether a 30 day beef intervention can improve peak cognitive performance in young, normally menstruating adult women. The control group will consume a daily portion of macronutrient equivalent vegetable source of protein.
