标题：Associations of Erythrocyte Polyunsaturated Fatty Acids with Inflammation and Quality of Life in Post-Menopausal Women with Obesity Completing a Pilot Dietary Intervention
摘要：Study objectives were to determine if erythrocyte omega-3 polyunsaturated fatty acids (n-3 PUFAs) increased in women participating in a dietary intervention that reduced inflammation and body weight and examine PUFA associations with markers of inflammation and quality of life (QOL). An experimental pre-post test, single group design was used. Fifteen post-menopausal women with obesity were enrolled in a 12-week pilot intervention focusing on lowering added sugars and increasing fiber and fish rich in n-3 PUFAs. Measurements included fasting blood samples, anthropometric, lifestyle and dietary data collected at baseline, end of intervention (Week 12) and follow-up (Week 24). Primary outcomes were change in erythrocyte PUFAs and associations between erythrocyte PUFAs, QOL (Short Form 12), and inflammatory markers (interleukin-6, tumor necrosis factor-α-receptor 2, and high sensitivity C-reactive protein (CRP)). Fourteen women completed all intervention visits. Mean erythrocyte docosahexaenoic acid and arachidonic acid (AA) increased at Week 12 and Week 24 (p < 0.001 for both), while eicosapentaenoic acid increased at Week 24 (p < 0.01). After adjustment for percent weight change, week 12 QOL related to physical function was significantly associated with erythrocyte linoleic acid (p < 0.05) and trended toward significant association with EPA (p = 0.051); week 24 CRP was directly associated with erythrocyte AA (p < 0.05). Erythrocyte n-3 PUFAs were not associated with inflammation.
