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.
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.
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.
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.
研究食物不安全与体重异常之间的关系得出了各种相互矛盾的结果。因此，进行了系统评价和荟萃分析，以检验成年人中食物不安全与体重异常之间的关系。
通过检索 PubMed 和 Scopus 数据库，截至 2018 年 2 月，确定了相关研究。这些研究的数据来源于 31 项研究。这些研究在 14 个不同的国家进行。对这些研究中的 115993 名个体的比值比进行荟萃分析。
本荟萃分析表明，处于食物不安全家庭中的成年人肥胖的风险更高（OR 1.15，95%CI 1.06-1.23）。按性别进行的亚组分析也表明，与男性相比，女性在食物不安全家庭中肥胖的风险更高（OR 1.26，95%CI 1.05-1.46）。此外，按食物不安全程度的亚组分析表明，家庭食物不安全的严重程度可能与成年人中体重过轻（49%）的风险高于超重（37%）或肥胖（29%）有关。此外，亚组分析表明，随着国家经济发展水平的降低，体重异常的风险从肥胖转向体重不足。
似乎处于食物不安全家庭中的成年人，尤其是女性，肥胖的风险更高。体重异常的风险可能随着食物不安全程度的加剧而增加。此外，经济发展水平是食物不安全对体重状况影响的一个重要因素。然而，由于研究之间存在高度异质性，结果应谨慎解释。
