While the direct benefits of food assistance programs are well-documented, there is a need to explore indirect benefits like increased physical activity. This study examined whether participation in the Supplemental Nutrition Assistance Program (SNAP) was associated with improved physical activity levels in children and adolescents aged 2-17 in the United States during 2017-2018. A cross-sectional study.
This cross-sectional study used a subset of National Health and Nutrition Examination Survey (NHANES) data (n=2620). In the NHANES 2017-2018 dataset, physical activity was measured through self-report questionnaires, which captured participants' frequency, duration, and intensity of various activities. We used weighted logistic regression and the Hosmer - Lemeshow - Sturdivant forward model - building strategy to investigate this hypothesized association using SAS version 9.4.
In the adjusted model, controlling for the other variables in the model, we found that children and adolescents from households that had received SNAP/Food Stamps had 1.53 times higher odds (odds ratio [OR]=1.53, 95% CI: 1.24-1.89) of achieving the recommended guidelines of 60 minutes of daily physical activity compared to those who had not received benefits. Each additional year of age resulted in 0.82 times lower odds (OR=0.82; 95% CI: 0.79, 0.85) of meeting the recommended amounts of physical activity. Additionally, each unit increase in BMI was associated with 0.96 times lower odds (OR=0.96, 95% CI: 0.93, 0.98) of engaging in recommended physical activity.
These findings suggest that participation in the SNAP/Food Stamps program may indirectly benefit participants by increasing physical activity levels.
虽然食品援助计划的直接效益有据可查，但仍有必要探索间接效益，例如增加身体活动量。本研究旨在探讨 2017-2018 年期间，美国 2-17 岁儿童和青少年参加补充营养援助计划（SNAP）是否与身体活动水平提高有关。本研究为横断面研究。
本横断面研究使用了国家健康和营养调查（NHANES）数据的一个子集（n=2620）。在 2017-2018 年的 NHANES 数据集中，通过自我报告问卷来衡量身体活动，该问卷记录了参与者各种活动的频率、持续时间和强度。我们使用加权逻辑回归和 Hosmer - Lemeshow - Sturdivant 正向模型构建策略，使用 SAS 版本 9.4 来调查这种假设的关联。
在调整后的模型中，控制了模型中的其他变量，我们发现，与未获得福利的儿童和青少年相比，来自获得 SNAP/食品券家庭的儿童和青少年，达到每天 60 分钟身体活动推荐指南的可能性要高出 1.53 倍（优势比[OR]=1.53，95%置信区间[CI]：1.24-1.89）。年龄每增加 1 岁，达到推荐身体活动量的可能性就会降低 0.82 倍（OR=0.82；95%CI：0.79, 0.85）。此外，BMI 每增加 1 个单位，参与推荐身体活动的可能性就会降低 0.96 倍（OR=0.96，95%CI：0.93, 0.98）。
这些发现表明，参加 SNAP/食品券计划可能会通过增加身体活动水平间接使参与者受益。
