Household food insecurity (HFI) may increase obesity risk, but results are not consistent across the life course or between developed/underdeveloped settings. The objective of this paper is to review findings from previous analyses in Brazil among adult women, female adolescents, and children up to five. Data were derived from the 2006 Brazilian Demographic and Health Survey. Associations between HFI (measured with the Brazilian Food Insecurity Scale) and excess weight/obesity were investigated through Poisson regression models. While severe HFI was associated with obesity risk among adult women (PR: 1.49; 95%CI: 1.17-1.90), moderate HFI was associated with excess weight among female adolescents (PR: 1.96; 95%CI: 1.18-3.27). There was no association between HFI and obesity among children (either boys or girls). The nutrition transition in Brazil may be shaping the differential deleterious effect of HFI on body fat accumulation across the life course; the association is already evident among female adolescents and adult women but still not among children.
家庭食物不安全（HFI）可能会增加肥胖风险，但在整个生命周期或发达国家/发展中国家之间的结果并不一致。本文的目的是回顾之前在巴西进行的针对成年女性、少女和五岁以下儿童的分析结果。数据来自 2006 年巴西人口与健康调查。通过泊松回归模型研究 HFI（用巴西食物不安全量表测量）与超重/肥胖之间的关联。虽然严重的 HFI 与成年女性肥胖风险相关（PR：1.49；95%CI：1.17-1.90），但中度 HFI 与少女超重相关（PR：1.96；95%CI：1.18-3.27）。HFI 与儿童肥胖（男孩或女孩）之间没有关联。巴西的营养转型可能正在塑造 HFI 对整个生命周期中体脂肪积累的不同有害影响；这种关联在少女和成年女性中已经很明显，但在儿童中仍然没有。
