The accumulation of abdominal visceral (VAT) and subcutaneous adipose tissue (SAT) has been closely correlated with an array of metabolic disorders and chronic inflammation. This study elucidated the joint effects of a dietary inflammatory index (DII) and vigorous intensity physical activity (PA) on VAT and SAT.
The study enrolled 3,444 adults sourced from the National Health and Nutrition Examination Survey (NHANES). The NHANES is designed with a sophisticated, multistage probability sampling methodology and is specifically tailored to comprehensively assess the health and nutritional conditions of the non-institutionalized population. Utilizing the initial 24 h dietary recall data from the NHANES database, our analysis incorporated 28 distinct food parameters for calculating the DII score. Multiple linear regression models are used to calculate the β value and 95% confidence interval of independent and dependent variables.
Compared with the pro-inflammatory diet group, VAT and SAT in the anti-inflammatory diet group were lower [-21.60 (-32.63, -10.58, P < 0.01) and - 85.67 (-108.80, -62.55, P < 0.01)]. The VAT and SAT in the sufficient vigorous intensity PA group were lower than those in the insufficient vigorous intensity PA group [-27.13 (-38.40, -15.86), P < 0.01; -57.05 (-80.82, -33.27), P < 0.01]. There was a linear positive association between DII with VAT (P < 0.01, P for nonlinearity = 0.13) and SAT (P < 0.01, P for nonlinearity = 0.06). Additionally, there were significant L-shaped relationships between vigorous intensity PA with VAT and SAT (all log-likelihood ratio P < 0.05).
A lifestyle of anti-inflammatory diet incorporated with sufficient vigorous intensity PA was associated with lower VAT and SAT. Notably, the increase of vigorous intensity PA is associated with the decrease of VAT and SAT in the L-shaped relationships, suggesting that the vigorous intensity PA with at least 75 min per week may be related to greater benefits of VAT.
腹部内脏脂肪（VAT）和皮下脂肪组织（SAT）的积累与一系列代谢紊乱和慢性炎症密切相关。本研究阐明了饮食炎症指数（DII）和高强度体力活动（PA）对VAT和SAT的联合影响。
该研究纳入了来自美国国家健康与营养检查调查（NHANES）的3444名成年人。NHANES采用复杂的多阶段概率抽样方法设计，专门用于全面评估非机构化人群的健康和营养状况。利用NHANES数据库中最初的24小时饮食回忆数据，我们的分析纳入了28个不同的食物参数来计算DII分数。使用多元线性回归模型计算自变量和因变量的β值和95%置信区间。
与促炎饮食组相比，抗炎饮食组的VAT和SAT较低[-21.60（-32.63，-10.58，P<0.01）和-85.67（-108.80，-62.55，P<0.01）]。高强度体力活动充足组的VAT和SAT低于高强度体力活动不足组[-27.13（-38.40，-15.86），P<0.01；-57.05（-80.82，-33.27），P<0.01]。DII与VAT（P<0.01，非线性P=0.13）和SAT（P<0.01，非线性P=0.06）之间存在线性正相关。此外，高强度体力活动与VAT和SAT之间存在显著的L形关系（所有对数似然比P<0.05）。
抗炎饮食与充足的高强度体力活动相结合的生活方式与较低的VAT和SAT相关。值得注意的是，在L形关系中，高强度体力活动的增加与VAT和SAT的减少相关，这表明每周至少75分钟的高强度体力活动可能与VAT的更大益处有关。
