A causal relationship between hunger and obesity has been postulated. Two cross-sectional studies have found evidence to suggest an association between obesity and food insecurity among adult women, and a third study suggests an association between underweight and food insecurity among men. The purpose of this study was to investigate the association between concern about enough food and obesity in an adult population at the state level.
A cross-sectional analysis was conducted using 1999 data from the Behavioral Risk Factor Surveillance System (BRFSS), Social Context Module (n = 3,945).
An 8.0% prevalence of concern about enough food was found in Louisiana, and an 11.8% prevalence was found in New York, and was positively associated with morbid obesity, RR = 2.20 (95% CI = 1.24, 3.90) and RR = 2.23 (95% CI = 1.30, 3.84), respectively. However, this association became nonsignificant after controlling for education, income, race/ethnicity, marital status, and general health.
A very strong apparent relationship between concern about enough food and obesity could be entirely accounted for by the influences of socioeconomic variables. This emphasizes the need for longitudinal research studies using precise measures of weight, height, and food security.
饥饿与肥胖之间的因果关系已被提出。两项横断面研究发现有证据表明成年女性肥胖与粮食不安全之间存在关联，第三项研究表明男性体重不足与粮食不安全之间存在关联。本研究的目的是在州一级的成年人群中调查对食物充足性的担忧与肥胖之间的关联。
使用行为风险因素监测系统（BRFSS）社会背景模块1999年的数据进行横断面分析（n = 3945）。
在路易斯安那州，对食物充足性表示担忧的患病率为8.0%，在纽约为11.8%，且与病态肥胖呈正相关，相对危险度（RR）分别为2.20（95%可信区间[CI] = 1.24，3.90）和RR = 2.23（95%CI = 1.30，3.84）。然而，在控制了教育程度、收入、种族/族裔、婚姻状况和总体健康状况后，这种关联变得不显著。
对食物充足性的担忧与肥胖之间非常明显的关系可能完全由社会经济变量的影响所解释。这强调了需要进行纵向研究，使用精确的体重、身高和粮食安全测量方法。
