Reduced quality of life (QOL) is a major public health challenge affecting the global population. Fatty acid quality indices (FAQIs) are novel determinants of QOL and may impact various aspects of QOL. Prior research has established a significant link between dietary habits and QOL. However, the association between FAQIs and specific dimensions of QOL has not been established. Therefore, we aimed to investigate the association between FAQIs and QOL in overweight and obese women.
In total, 378 adult overweight or obese women participated in this cross-sectional study. Several anthropometric indices, systolic and diastolic blood pressure, and biochemical factors were measured using standard protocols. Dietary intake was assessed using a validated and reliable semi-quantitative food frequency questionnaire (the FFQ, 147 items). The cholesterol-saturated fat index (CSI) and the ratio of omega-6/omega-3 (N6/N3) essential fatty acids consumed were employed as FAQIs. The SF-36 questionnaire was administered to measure QOL. Linear logistic regression was used, in the form of raw and adjusted models, to evaluate the associations between FAQIs and QOL.
The study sample consisted of 279 participants for whom ω-6/ω-3 ratio was measured and 378 participants for whom CSI was measured. The mean (±SD) age of participants was 36.65 ± 9.07 years. Linear logistic regression, with adjustment for potential confounders, such as age, energy intake, body mass index, employment, and thyroid status, indicated that ω-6/ω-3 intake ratio was negatively and marginally significantly associated with general health (β = -139.94, 95% CI: [-286.54, 6.66]; = 0.061 and physical role limitations (β= -337.68, 95% CI: [-679.99, 1.61]; = 0.051). A significant negative association was observed between ω-6/ω-3 intake ratio and social functioning (β = -247.54, 95% CI: [-458.14, -36.94]; = 0.021), which indicates that obese and overweight women with a higher ω-6/ω-3 intake ratio obtained lower scores on social functioning.
It was found that FAQI scores were negatively associated with certain QOL measures among overweight and obese Iranian women, suggesting that a higher consumption of fatty acids, especially trans and saturated fatty acids, may be associated with lower QOL.
生活质量(QOL)下降是影响全球人口的主要公共卫生挑战。脂肪酸质量指数(FAQI)是 QOL 的新决定因素,可能会影响 QOL 的各个方面。先前的研究已经确定了饮食习惯与 QOL 之间存在显著联系。然而,FAQIs 与特定的 QOL 维度之间的关联尚未建立。因此,我们旨在研究超重和肥胖女性中 FAQIs 与 QOL 之间的关系。
共有 378 名成年超重或肥胖女性参与了这项横断面研究。使用标准方案测量了几项人体测量指数、收缩压和舒张压以及生化因素。使用经过验证和可靠的半定量食物频率问卷(FFQ,147 项)评估饮食摄入量。胆固醇-饱和脂肪指数(CSI)和消耗的ω-6/ω-3(N6/N3)必需脂肪酸的比例被用作 FAQI。采用 SF-36 问卷来衡量 QOL。使用线性逻辑回归,以原始和调整后的模型形式,评估 FAQIs 与 QOL 之间的关系。
该研究样本包括 279 名参与者,其中测量了 ω-6/ω-3 比例,378 名参与者测量了 CSI。参与者的平均(±SD)年龄为 36.65±9.07 岁。经过潜在混杂因素的调整,如年龄、能量摄入、体重指数、就业和甲状腺状况,线性逻辑回归表明 ω-6/ω-3 摄入比例与一般健康(β=-139.94,95%CI:[-286.54,6.66]; = 0.061)和身体角色限制(β=-337.68,95%CI:[-679.99,1.61]; = 0.051)呈负相关且具有边际显著性。观察到 ω-6/ω-3 摄入比例与社会功能之间存在显著负相关(β=-247.54,95%CI:[-458.14,-36.94]; = 0.021),这表明 ω-6/ω-3 摄入比例较高的超重和肥胖伊朗女性在社会功能方面的得分较低。
研究发现,FAQI 评分与超重和肥胖伊朗女性的某些 QOL 测量指标呈负相关,这表明食用更多的脂肪酸,尤其是反式和饱和脂肪酸,可能与较低的 QOL 相关。
