It has been proposed that a greater degree of adherence to a healthy dietary pattern is associated with a lower risk of depression and a poor quality of life (QoL). The Lifelines diet score (LLDS) is a new, evidence-base scoring system to define the quality of diet. We designed a cross-sectional study to investigate the association between LLDS with depression and QoL in Iranian adolescent girls.
A total of 733 female adolescents were recruited from Mashhad and Sabzevar cities, Iran. Depression and QoL were assessed utilizing the Beck Depression Inventory (BDI) and SF-12v2 questionnaires, respectively. The LLDS was defined by dividing intakes of 12 food groups with negative or positive health effects into quintiles ranging 12 to 60 points. To explore the association between LLDS with QoL and depression, logistic regression was used in crude and adjusted models.
The prevalence of depression and poor QoL was 24% and 49%, respectively. After adjusting for confounding factors, adolescent girls in the highest quartile of LLDS compared with the participants in the lowest quartile had a 42% lower probability of reporting depressive symptoms (OR: 0.58; 95% CI: 0.35-0.97, P = 0.03). In addition, the participants in the highest quartile of LLDS had lower odds of poor QoL compared with the subjects in the lowest quartile (OR: 0.65; 95% CI: 0.42-0.92, P = 0.04).
There is an inverse relationship between LLDS with risk of depression and poor QoL. Prospective and interventional investigations are needed to reach a clear vision.
有研究提出，更严格遵循健康的饮食模式与降低抑郁风险和提高生活质量（QoL）有关。生活方式饮食评分（LLDS）是一种新的、基于证据的评分系统，用于定义饮食质量。我们设计了一项横断面研究，旨在调查伊朗少女的 LLDS 与抑郁和 QoL 之间的关系。
共招募了来自伊朗马什哈德和萨布泽瓦尔市的 733 名女性青少年。使用贝克抑郁量表（BDI）和 SF-12v2 问卷分别评估抑郁和 QoL。LLDS 通过将具有负面或正面健康影响的 12 种食物组的摄入量分为五分位数来定义，范围为 12 至 60 分。为了探讨 LLDS 与 QoL 和抑郁之间的关系，我们在原始和调整后的模型中使用了逻辑回归。
抑郁和 QoL 不良的发生率分别为 24%和 49%。在调整混杂因素后，与最低四分位组相比，LLDS 最高四分位组的青少年女孩报告抑郁症状的可能性降低了 42%（OR：0.58；95%CI：0.35-0.97，P=0.03）。此外，与最低四分位组相比，LLDS 最高四分位组的青少年女孩出现 QoL 不良的可能性降低了 35%（OR：0.65；95%CI：0.42-0.92，P=0.04）。
LLDS 与抑郁风险和 QoL 不良呈负相关。需要进行前瞻性和干预性研究以得出明确的结论。
