Feeling connected to nature, or nature relatedness (NR), can positively impact physical and psychological well-being. However, the relationship between NR and dietary behaviors has not been studied. This research examined the relationship between NR and dietary behaviors, including dietary diversity and fruit and vegetable intake.
Cross-sectional online survey study.
Philadelphia, Pennsylvania.
Adults (n = 317) over 18 years who resided in Philadelphia, PA.
The NR Scale was used to measure participants' connection to nature. It includes 21 items across three subscales: self, experience, and perspective (total and subscales range from 1 to 5). Dietary Diversity was assessed using the FAO's standardized tool (scores range from 0 to 9). To calculate dietary diversity, food groups reported were aggregated into nine food categories: starchy staples; dark green leafy vegetables; vitamin A rich fruits/vegetables; other fruits/vegetables; organ meat; meat/fish; eggs; legumes, nuts/seeds; and milk products. The NCI's 2-item CUP Fruit and Vegetable Screener was used to estimate daily fruit and vegetable intake (cups/day), and socio-demographic questions were asked.
Simple and multivariable regression models were used to examine associations between NR Total and subscale scores with dietary diversity scores and fruit and vegetable intake with NR Total scores and subscale scores. The multivariable models were adjusted for age, race, gender, and income.
People with higher NR Total ( < .001), NR Self (P < .001), NR Perspective (P = .002), and NR Experience (P = .002) were more likely to report greater dietary diversity. Those with higher NR Total (P < .001), NR Self (P < .001), and NR Experience (P < .001) reported greater fruit and vegetable intake. Associations remained significant after adjusting for covariates.
NR was associated with better dietary intake after accounting for socio-demographic indicators. These findings highlight the need for health promotion interventions that enhance NR, such as nature prescription initiatives, urban gardening and greening, and immersion in urban green spaces.
与大自然建立联系或与自然相关（NR）可以对身心健康产生积极影响。然而，NR 与饮食行为之间的关系尚未得到研究。本研究调查了 NR 与饮食行为之间的关系，包括饮食多样性和水果和蔬菜摄入量。
横断面在线调查研究。
宾夕法尼亚州费城。
18 岁以上居住在宾夕法尼亚州费城的成年人（n = 317）。
使用 NR 量表衡量参与者与自然的联系。它包括三个子量表的 21 个项目：自我、体验和视角（总分和子量表范围为 1 到 5）。饮食多样性使用粮农组织的标准化工具进行评估（得分范围为 0 到 9）。为了计算饮食多样性，报告的食物组被汇总成九类食物：淀粉主食；深绿色叶菜；富含维生素 A 的水果/蔬菜；其他水果/蔬菜；器官肉；肉/鱼；鸡蛋；豆类、坚果/种子；和奶制品。使用 NCI 的 2 项 CUP 水果和蔬菜筛查器估计每日水果和蔬菜摄入量（杯/天），并询问社会人口统计学问题。
简单和多变量回归模型用于检查 NR 总分和子量表评分与饮食多样性评分以及 NR 总分和子量表评分与水果和蔬菜摄入量之间的关联。多变量模型调整了年龄、种族、性别和收入。
NR 总分较高（<.001）、NR 自我（<.001）、NR 视角（P =.002）和 NR 体验（P =.002）的人更有可能报告更高的饮食多样性。NR 总分较高（<.001）、NR 自我（<.001）和 NR 体验（<.001）的人报告的水果和蔬菜摄入量更多。调整协变量后，关联仍然显著。
在考虑社会人口统计学指标后，NR 与更好的饮食摄入相关。这些发现强调了需要开展健康促进干预措施，增强 NR，例如开具自然处方倡议、城市园艺和绿化以及沉浸在城市绿地中。
