亚洲AV professor says that one of the biggest international problems we face is mothers and children worldwide chronically suffering from food insecurity and a lack of nutrition. Gewa, whose research has focused on countries in Africa, says that undernutrition can start in utero and get worse from there.
When children start their lives in poor nutritional status and it continues, there can be significant long-term consequences, said Gewa, an assistant professor in the Department of Nutrition and Food Studies. For example, childhood stunting has been associated with reduced development and poor academic and work performance.
鈥淲hen undernourished women become pregnant, it can affect their children鈥檚 overall health right away,鈥 Gewa said. 鈥淭heir children are likely to suffer from intrauterine growth retardation, low-birth weight and might not even survive or, if they do survive, they could struggle and fail to thrive. If they continue to face food insecurity and a lack of nutrition, their health and developmental problems will escalate.鈥
Gewa said there needs to be particular attention paid to young women, even before they become pregnant, to ensure that they are well-nourished and as healthy as possible.
鈥淎ddressing nutritional concerns and supporting the health of women and girls, at pre-conception, during pregnancies and between pregnancies, could help break the cycle of malnutrition,鈥 said Gewa. 鈥淚t鈥檚 a start, but it can鈥檛 end there.鈥
In addition, Gewa said it鈥檚 important to promote healthy child-feeding practices such as breastfeeding whenever possible.
鈥淲e know that the best and safest food for a baby is breast milk,鈥 Gewa said. 鈥淚n low-income nations, we promote breast feeding because we know it is safe and nutritious, but if a mother isn鈥檛 well-nourished then it is difficult for her to breastfeed her young child as recommended.鈥
Gewa鈥檚 work has highlighted high rates of food insecurity in small households in rural Kenya and the disconnection between promoted agricultural practices and the nutrition of mothers and children.
In general, she said, adopting agricultural policies that are nutrition-sensitive can lead to improved health and nutrition for mothers and children.
Small farm households 鈥渁re most vulnerable to malnutrition. However, a number of agricultural policies are not sensitive鈥 to poor farmers鈥 needs, said Gewa. 鈥淚f the agricultural policies in a certain area do not promote healthful foods that a family can sustainably farm and consume, then that can lead to food and nutrition insecurity.鈥
Gewa is a leading expert in estimation of dietary intake quantity and quality in African populations, sustainable food-based strategies aimed at improving food security and nutritional and health status of mothers and children populations in resource-poor settings in Africa and diet-related behavior change. Gewa also worked as a nutrition team leader and a project coordinator with a child nutrition research project in Kenya.
