The purpose of this study was to investigate and describe the nutritional status, dietary intake and dietary diversity of waste pickers in South Africa, a socioeconomically vulnerable group who makes a significant contribution to planetary health through salvaging recyclable material from dumpsites. Participants were weighed and measured to calculate body mass index (BMI). Dietary intake was recorded using a standardised multipass 24 h recall. Individual dietary diversity scores were derived from the dietary recall data. Data were collected from nine purposefully selected landfill sites located in six rural towns and three cities in four of the nine provinces in South Africa, providing nutritional status information on 386 participants and dietary intake on 358 participants after data cleaning and coding. The mean BMI of the study sample was 23.22 kg/m. Underweight was more prevalent among males (22.52%) whilst 56.1% of the females were overweight or obese. The average individual dietary diversity score was 2.46, with 50% scoring 2 or less. Dietary intake patterns were characterised as monotonous, starch-based and lacking vegetables and fruits. The nutritional status, dietary intake and dietary diversity of waste pickers reflect their precarious economic status, highlighting the need for health, social and economic policies to improve access and affordability of nutritious food.
本研究旨在调查和描述南非拾荒者的营养状况、饮食摄入和饮食多样性，他们是社会经济弱势群体，通过从垃圾填埋场中回收可回收材料，为地球健康做出了重大贡献。参与者接受了称重和测量，以计算身体质量指数 (BMI)。饮食摄入通过标准化的多次 24 小时回忆记录。从饮食回忆数据中得出个体饮食多样性得分。数据来自南非九个省份中的四个省份的六个农村城镇和三个城市的九个有针对性选择的垃圾填埋场，为 386 名参与者提供了营养状况信息，为 358 名参与者提供了饮食摄入信息，在数据清理和编码后。研究样本的平均 BMI 为 23.22kg/m。男性中体重过轻更为普遍（22.52%），而 56.1%的女性超重或肥胖。平均个体饮食多样性得分为 2.46，有 50%的得分在 2 或以下。饮食摄入模式的特点是单调、以淀粉为基础，缺乏蔬菜和水果。拾荒者的营养状况、饮食摄入和饮食多样性反映了他们不稳定的经济状况，突出了需要健康、社会和经济政策来改善营养食品的可及性和可负担性。
