A new study conducted by scientists in the U.S. has pointed out that living in a food-insecure household during pregnancy may up the risk of greater weight gain and pregnancy complications.
Household food insecurity, the inability to obtain nutritious and safe foods in socially acceptable ways, is increasingly recognized as an independent risk factor for many poor health outcomes among women.
AdvertisementPrevious studies have shown that paradoxically, women living in food insecure households report higher rates of overweight and related health complications.
"The present study was conducted to estimate the association between household food insecurity status and maternal health during pregnancy, when changes in both body weight and overall health can be dramatic," according to Barbara A. Laraia, and co-authors.
"The results suggest that the experience of living in a food insecure household was associated with metabolic health indicators during pregnancy.
"Not only was living in a food insecure household associated with severe pregravid obesity-a condition that broadly predisposes women to adverse pregnancy outcomes-but also with greater gestational weight gain and gestational diabetes mellitus," she added.
Researchers from the University of North Carolina, Chapel Hill, and the US Department of Agriculture's Economic Research Service, Washington, DC, used data from the Pregnancy, Infection and Nutrition prospective cohort study-810 pregnant women with incomes less than 400 percent of the income/poverty ratio were followed through their pregnancies.
This household income restriction allowed better comparison among households that might have food insecurity due to financial and material constraints. In this group, 76 percent were from fully food secure, 14 percent were from marginally food secure, and 10 percent were from food insecure households.
A significant finding that emerged is the association between household food insecurity and development of GDM.
The authors observed that the combined group of women from marginally secure and insecure food households had more than twice the odds of developing GDM than women in food secure households, suggesting that women living in a household with any level of food insecurity may be at risk.
The study has been published in the May issue of the Journal of the American Dietetic Association.
