BACKGROUND
Levels of salt consumption and its awareness among medical students in Angola remain insufficiently studied. This study determined salt intake and assessed medical students' knowledge, attitude and behaviour regarding salt consumption.
METHODS
Were collected 24-hour urine samples from a random sample of 123 undergraduate medical students aged 17-43 years who were studying at the University of Agostinho Neto in Luanda. Their knowledge, attitude and behaviour regarding dietary salt were surveyed. Socio-demographic, clinical and anthropometric data were collected.
RESULTS
Average salt intake was 14.2 ± 5.1 g/day, without significant difference between genders (p = 0.221). In total, 96.7% consumed over 5 g/day, but only 6.5% of participants were aware of their excessive salt intake. The majority knew about salt-related health consequences and 45.5% reported they controlled their salt intake.
CONCLUSIONS
This study indicated a high salt intake and inadequate behaviour regarding dietary salt consumption among medical students studying at the University of Agostinho Neto. This highlights the need for nutritional education to improve their dietary habits and future role in counselling.
背景
安哥拉医学生的盐摄入量及其认知水平仍未得到充分研究。本研究测定了盐摄入量，并评估了医学生关于盐摄入的知识、态度和行为。
方法
从罗安达阿戈斯蒂纽·内图大学123名年龄在17 - 43岁的本科医学生随机样本中收集24小时尿液样本。调查了他们关于膳食盐的知识、态度和行为。收集了社会人口学、临床和人体测量数据。
结果
平均盐摄入量为14.2±5.1克/天，性别之间无显著差异（p = 0.221）。总计96.7%的人每天盐摄入量超过5克，但只有6.5%的参与者意识到自己盐摄入过量。大多数人知道与盐相关的健康后果，45.5%的人报告他们控制盐摄入量。
结论
本研究表明，在阿戈斯蒂纽·内图大学学习的医学生盐摄入量高，且在膳食盐消费方面行为不当。这凸显了开展营养教育以改善他们的饮食习惯及其未来咨询工作中作用的必要性。
