Why is this important?
Access to a healthy and balanced diet promotes good metabolic health, especially during pregnancy. However, it has been described that people with a low socio-economic level tend to have poorer quality nutrition. Moreover, the fact of living in a food desert, that is to say a territory in which it is difficult to obtain healthy food, would favor a diet less favorable for health. However, there is an interaction between living in a food desert and having a low socio-economic level. These two types of association are detrimental to the metabolic health of pregnant women. However, it was interesting to assess in the same study whether these two parameters both have an independent influence and whether the extent of the food desert influences the relationship between socio-economic level and metabolism.
This study is useful because it makes it possible to identify the people most likely to present a metabolic risk during pregnancy and to better understand with whom to develop specific interventions (community gardens, training/education in food preparation, establishments of grocery stores or supermarkets…).
Methodology
This study was conducted in Oregon (USA) using a cohort of pregnant women aged 18 to 40, recruited and followed prospectively between 2018 and 2021. The oral glucose tolerance test, the percentage adiposity and information on the nature of the participants’ nutritional intake were obtained during the second trimester of pregnancy.
Principle results
In total, the study recruited 302 women (mean age 31.94 years). A high food desert severity score was associated with greater adiposity and lower socioeconomic status. At the same time, low socioeconomic status was associated with low socioeconomic level, greater adiposity and pro-inflammatory diet. The severity of the food desert significantly influenced the relationship between having low socioeconomic status and the extent of adiposity during the second trimester of pregnancy.
When the statistical model aimed to test the hypothesis that food desert severity significantly mediates the relationship between socioeconomic level and gestational metabolism (by regressing metabolic parameters on socioeconomic level and food desert severity) , having a low socioeconomic status was associated with a high food desert severity score, increased adiposity, and a more pro-inflammatory diet. However, it was not associated with glycemic control.
