RATIONALE
Food insecurity during pregnancy is concerning given the increased nutritional needs of the mother for proper fetal development. However, research is lacking within the South African context to investigate the association of economic and psychosocial factors and food insecurity among pregnant women, using comprehensive, conceptually driven models.
OBJECTIVE
This study applies the Network-Individual-Resource (NIR) Model to investigate individual, intimate dyadic, and family level predictors of perceived household food insecurity for pregnant women.
METHODS
826 pregnant women enrolled in the Drakenstein Child Health Study (DCHS), a birth cohort in two communities in a peri-urban area of South Africa. Hierarchical logistic regressions were used to investigate the impact of household/family, intimate dyads, and individual tangible and mental resources on perceived household food insecurity during the critical period of pregnancy. Perceived household food insecurity was assessed through an adapted version of the USDA Household Food Security Scale - Short Form.
RESULTS
Among 826 pregnant women in South Africa, individual-level tangible resources (e.g. income, social assistance, HIV status) and mental resources (e. g. depression, childhood trauma) predicted perceived household food insecurity and these predictors differed by community. Intimate dyadic and family level resources did not predict household food insecurity.
CONCLUSIONS
Our findings of the economic and psychosocial predictors of perceived household food insecurity among pregnant women in South Africa, mirror findings in general populations. This study provides support for the extension of the NIR model to perceived household food insecurity, particularly regarding individual-level mental and tangible resources, as well as the impact of community-level factors. Future research should investigate the extent to which resource sharing occurs within networks.
背景
考虑到母亲在适当胎儿发育方面的营养需求增加，怀孕期间的粮食不安全问题令人担忧。然而，在南非背景下，缺乏使用全面、概念驱动的模型来研究经济和社会心理因素与孕妇粮食不安全之间的关系的研究。
目的
本研究应用网络-个体-资源（NIR）模型来调查孕妇对家庭粮食不安全的感知的个体、亲密关系和家庭层面的预测因素。
方法
826 名孕妇参加了德肯斯坦儿童健康研究（DCHS），这是南非一个城市周边地区的两个社区的一个出生队列。分层逻辑回归用于调查家庭/家庭、亲密关系和个体有形和心理资源对怀孕关键期家庭粮食不安全的影响。通过美国农业部家庭粮食安全量表-短表的改编版本评估家庭粮食不安全的感知。
结果
在南非的 826 名孕妇中，个体有形资源（如收入、社会援助、HIV 状况）和心理资源（如抑郁、童年创伤）预测了家庭粮食不安全，这些预测因素因社区而异。亲密关系和家庭层面的资源并不能预测家庭粮食不安全。
结论
我们发现南非孕妇对家庭粮食不安全的感知的经济和社会心理预测因素，与一般人群的发现相吻合。本研究为将 NIR 模型扩展到对家庭粮食不安全的感知提供了支持，特别是在个体层面的心理和有形资源以及社区层面因素的影响方面。未来的研究应该调查网络内资源共享的程度。
