Psychosocial factors are important determinants of health behaviors and diet-related outcomes, yet relatively little work has explored their relation to food-purchasing and preparation behaviors in low-income populations.
To evaluate the psychosocial factors associated with food-related behaviors.
Cross-sectional data collected from 465 low-income African American adult caregivers in the baseline evaluation of the B'more Healthy Communities for Kids obesity prevention trial. Questionnaires were used to assess household sociodemographic characteristics, food sources frequently used, and food preparation and food acquisition behaviors. Multiple linear regression models explored the associations between caregiver psychosocial variables and food-related behaviors, controlling for caregivers' age, sex, household income, household size, and food assistance participation.
Caregivers purchased prepared food at carry-outs on average 3.8 times (standard deviation [ SD] = 4.6) within 30 days. Less healthy foods were acquired 2 times more frequently than healthier foods ( p < .001). Higher food-related behavioral intention and self-efficacy scores were positively associated with healthier food acquisition (β = 0.7; 95% confidence interval [CI] [0.09, 1.4]; β = 0.04; 95% CI [0.02, 0.06]) and negatively associated with frequency of purchasing at prepared food sources (β = -0.4; 95% CI [-0.6, -0.2]; β = -0.5; 95% CI [-0.7, -0.3]), respectively. Higher nutrition knowledge was associated with lower frequency of purchasing food at prepared food venues (β = -0.7; 95% CI: [-1.2, -0.2]).
Our findings indicate a positive association between psychosocial determinants and healthier food acquisition and food preparation behaviors.
Interventions that affect psychosocial factors (i.e., food-related behavioral intentions and self-efficacy) may have the potential to increase healthier food preparation and food-purchasing practices among low-income African American families.
社会心理因素是健康行为和饮食相关结果的重要决定因素，但相对较少的工作探讨了它们与低收入人群的食物购买和准备行为的关系。
评估与食物相关行为相关的社会心理因素。
横断面数据来自于 465 名低收入非裔美国成年照顾者，他们是 B'more Healthy Communities for Kids 肥胖预防试验基线评估的一部分。问卷用于评估家庭社会人口统计学特征、经常使用的食物来源以及食物准备和获取行为。多线性回归模型探讨了照顾者社会心理变量与食物相关行为之间的关系，控制了照顾者的年龄、性别、家庭收入、家庭规模和食物援助参与情况。
照顾者在 30 天内平均购买外卖准备食物 3.8 次（标准差[SD]=4.6）。获取不太健康的食物的频率比获取更健康的食物高两倍（p<0.001）。较高的食物相关行为意向和自我效能得分与获取更健康的食物呈正相关（β=0.7；95%置信区间[CI] [0.09, 1.4]；β=0.04；95%CI [0.02, 0.06]），与在准备食物来源购买食物的频率呈负相关（β=-0.4；95%CI [-0.6, -0.2]；β=-0.5；95%CI [-0.7, -0.3]）。较高的营养知识与在准备食物场所购买食物的频率较低相关（β=-0.7；95%CI：[-1.2, -0.2]）。
我们的发现表明，社会心理决定因素与更健康的食物获取和准备行为之间存在正相关。
影响社会心理因素（即与食物相关的行为意向和自我效能）的干预措施可能有潜力增加低收入非裔美国家庭更健康的食物准备和购买习惯。
