Chronic low back pain (LBP) is the most common musculoskeletal pain that affects a person's daily activities. This present study aimed at evaluating the relationship between major dietary pattern and Chronic LBP.
This cross-sectional analysis was examined 7686 Kurdish adults. The RaNCD cohort study physician diagnosed chronic LBP. Dietary patterns were derived using principal component analysis. The three identified dietary patterns derived were named: 1) the vegetarian diet included vegetables, whole grain, legumes, nuts, olive, vegetable oil, fruits, and fruit juice; 2) high protein diet related to higher adherence to red and white meat, legumes, nuts, and egg; and 3) energy-dense diet characterized with higher intake of salt, sweet, dessert, hydrogenated fat, soft drink, refined grain, tea, and coffee. Dietary pattern scores were divided into tertiles. Binary logistic regression in crude, adjusted odds ratios (OR) and 95% confidence intervals (CI) were used to determine this association.
Twenty-two per cent of participants had chronic LBP. Higher adherence to high protein dietary pattern was inversely associated with chronic LBP in crude (OR: 0.79, 95% CI: 0.69-0.9) and adjusted model (for age, sex, smoking, drinking, diabetes, physical activity, body mass index, and waist circumference) (OR: 0.84, 95% CI: 0.72-0.97). In addition, after controlling for the mentioned potential confounders, participants in the highest category of energy dense diet were positively associated with chronic LBP compared with those in the lowest category (OR: 1.13, 95% CI: 1.01-1.32).
Higher adherence to the high protein diet was inversely related to chronic LBP prevalence. In addition, we found that following energy dense diet was positively associated with chronic LBP.
慢性下腰痛（LBP）是最常见的肌肉骨骼疼痛，影响一个人的日常活动。本研究旨在评估主要饮食模式与慢性 LBP 之间的关系。
本横断面分析检查了 7686 名库尔德成年人。RaNCD 队列研究医生诊断为慢性 LBP。饮食模式采用主成分分析得出。得出的三种饮食模式分别命名为：1）素食饮食，包括蔬菜、全谷物、豆类、坚果、橄榄、植物油、水果和果汁；2）高蛋白饮食与更高的红、白肉、豆类、坚果和鸡蛋摄入量有关；3）高能量饮食的特点是摄入更多的盐、甜食、甜点、氢化脂肪、软饮料、精制谷物、茶和咖啡。饮食模式评分分为三分位。使用二元逻辑回归分析粗比值比（OR）和 95%置信区间（CI）来确定这种关联。
22%的参与者患有慢性 LBP。在调整年龄、性别、吸烟、饮酒、糖尿病、体力活动、体重指数和腰围等潜在混杂因素后，高蛋白质饮食模式的高摄入量与慢性 LBP 呈负相关（OR：0.79，95%CI：0.69-0.9）。此外，与最低分类相比，能量密集型饮食分类中最高的参与者与慢性 LBP 呈正相关（OR：1.13，95%CI：1.01-1.32）。
高蛋白饮食模式的高摄入量与慢性 LBP 的患病率呈负相关。此外，我们发现，遵循高能量密集型饮食与慢性 LBP 呈正相关。
