Among rural families, rates of both child obesity and household food insecurity (FI) are higher compared to non-rural families. These disparities result from a complex interplay of social and environmental conditions that influence behavior. The Transtheoretical Model suggests individual readiness to change underlies success in modifying obesity-preventing behaviors; however, whether an association between readiness to change obesity-related behaviors and FI status among rural families exists is unknown. We examined the association between readiness to change family-level nutrition and physical activity (PA) behaviors that predict child obesity and family FI status within a sample of rural families to better understand these relationships. Families ( = 144) were recruited from six rural Oregon communities in 2013. Families completed a FI screener and the Family Stage of Change Survey (FSOC), a measure of readiness to change family-level nutrition and PA behaviors associated with obesity. Demographic differences by FI status were explored, and regression was applied to examine relationships between FI and FSOC scores, adjusting for relevant covariates. Among FI families (40.2%), more were non-white (77.8% vs. 22.2%; = 0.036) and had lower adult education (30.4% vs. 11.8% with > high school degree; = 0.015) compared to non-FI families. After adjusting for education, race, ethnicity, and eligibility for federal meal programs, readiness to provide opportunities for PA was lower among FI families ( = 0.002). These data highlight a need to further investigate how food insecurity low readiness to provide PA opportunities, i.e. "physical activity insecurity" may be contributing to the higher obesity rates observed among rural children and families.
在农村家庭中，儿童肥胖率和家庭粮食不安全（FI）率均高于非农村家庭。这些差异源于影响行为的社会和环境条件的复杂相互作用。跨理论模型表明，个人改变的意愿是改变预防肥胖行为成功的基础；然而，农村家庭中与肥胖相关行为的改变意愿和FI状况之间是否存在关联尚不清楚。我们在一个农村家庭样本中研究了改变家庭层面营养和身体活动（PA）行为的意愿与家庭FI状况之间的关联，这些行为可预测儿童肥胖，以便更好地理解这些关系。2013年从俄勒冈州的六个农村社区招募了家庭（n = 144）。家庭完成了一份FI筛查问卷和家庭改变阶段调查（FSOC），这是一种衡量改变与肥胖相关的家庭层面营养和PA行为意愿的指标。探讨了FI状况导致的人口统计学差异，并应用回归分析来检验FI与FSOC分数之间的关系，并对相关协变量进行了调整。在FI家庭（40.2%）中，与非FI家庭相比，非白人比例更高（77.8%对22.2%；P = 0.036），成人教育程度较低（高中以上学历的比例为30.4%对11.8%；P = 0.015）。在调整了教育、种族、民族和联邦膳食计划资格后，FI家庭中提供PA机会的意愿较低（P = 0.002）。这些数据凸显了有必要进一步研究粮食不安全——即提供PA机会的意愿低，也就是“身体活动不安全”——可能如何导致农村儿童和家庭中观察到的较高肥胖率。
