Abstract

Purpose

Research into the relationship between food insecurity and weight abnormality has yielded varied and contradictory results. Therefore, a systematic review and meta-analysis were carried out to examine the association between food insecurity and weight abnormality in adults.

Methods

Pertinent studies were identified by searching PubMed and Scopus databases, up to February 2018. Data were available from 31 studies. These studies were conducted in 14 different countries. The odds ratio of 115,993 individuals in these studies was pooled for the meta-analysis.

Results

The present meta-analysis showed that adults in food-insecure households are more at risk of obesity (OR 1.15, 95% CI 1.06–1.23). Subgroup analysis by gender also revealed that women had a higher risk of obesity compared to men in food-insecure households (OR 1.26, 95% CI 1.05–1.46). Furthermore, subgroup analysis by food insecurity level implied that a severe level of household food insecurity may be associated with a higher risk of underweight (49%) than overweight (37%) or obesity (29%) among adults. In addition, subgroup analysis revealed that with lower levels of national economic development, the risk of weight abnormality shifted from obesity to underweight.

Conclusion

It seems that adults in food-insecure households, especially women, are at higher risk of obesity. The weight abnormality risk may increase with the intensification of the level of food insecurity. Also, the level of economic development is an important factor in the effects of food insecurity on weight status. However, due to the high heterogeneity among studies, the results should be interpreted with caution.
