Visceral adipose tissue (VAT) is a strong predictor of cardiometabolic health, and lifestyle factors may have a positive influence on VAT depot. This study aimed to assess the cross-sectional associations between baseline levels of physical activity (PA), sedentary behaviours (SB) and adherence to the Mediterranean diet (MedDiet) with VAT depot in older individuals with overweight/obesity and metabolic syndrome.
Baseline data of the PREDIMED-Plus study including a sample of 1,231 Caucasian men and women aged 55-75 years were used. Levels of leisure-time PA (total, light, and moderate-to-vigorous, in METs·min/day) and SB (total and TV-viewing, in h/day) were evaluated using validated questionnaires. Adherence to the MedDiet was evaluated using a 17-item energy-restricted MedDiet (erMedDiet) screener. The chair-stand test was used to estimate the muscle strength. VAT depot was assessed with DXA-CoreScan. Multivariable adjusted linear regression models were used to evaluate the association between lifestyle factors and VAT. For the statistics we had used multiadjusted linear regression models.
Total leisure-time PA (100 METs·min/day: β -24.3g, -36.7;-11.9g), moderate-to-vigorous PA (β -27.8g, 95% CI -40.8;-14.8g), chair-stand test (repeat: β -11.5g, 95% CI -20.1;-2.93g) were inversely associated, and total SB (h/day: β 38.2g, 95% CI 14.7;61.7) positively associated with VAT. Light PA, TV-viewing time and adherence to an erMedDiet were not significantly associated with VAT.
In older adults with overweigh/obesity and metabolic syndrome, greater PA, muscle strength, and lower total SB were associated with less VAT depot. In this study, adherence to an erMedDiet was not associated with lower VAT.
内脏脂肪组织(VAT)是代谢健康的强有力预测因子,生活方式因素可能对 VAT 沉积有积极影响。本研究旨在评估基线体力活动(PA)、久坐行为(SB)和地中海饮食(MedDiet)依从性与超重/肥胖和代谢综合征老年人 VAT 沉积的横断面关联。
使用 PREDIMED-Plus 研究的基线数据,包括 1231 名年龄在 55-75 岁的白种男女。使用经过验证的问卷评估了休闲时间 PA(总、轻、中-剧烈,以 METs·min/天)和 SB(总和 TV 观看时间,以 h/天)的水平。采用 17 项能量限制型 MedDiet(erMedDiet)筛查器评估 MedDiet 的依从性。使用椅子站立测试来估计肌肉力量。使用 DXA-CoreScan 评估 VAT 沉积。使用多变量调整线性回归模型评估生活方式因素与 VAT 之间的关系。对于统计分析,我们使用了多调整线性回归模型。
总休闲时间 PA(100 METs·min/天:β -24.3g,-36.7;-11.9g)、中-剧烈 PA(β -27.8g,95%CI -40.8;-14.8g)、椅子站立测试(重复)(β -11.5g,95%CI -20.1;-2.93g)呈负相关,总 SB(h/天:β 38.2g,95%CI 14.7;61.7)与 VAT 呈正相关。轻 PA、TV 观看时间和 erMedDiet 依从性与 VAT 无显著相关性。
在超重/肥胖和代谢综合征的老年人中,较高的 PA、肌肉力量和较低的总 SB 与较少的 VAT 沉积有关。在这项研究中,MedDiet 的依从性与较低的 VAT 无关。
