Diet, obesity and adipokines play important roles in diabetes and CVD; yet, limited studies have assessed the relationship between diet and multiple adipokines. This cross-sectional study assessed associations between diet, adiposity and adipokines in Mexican Americans. The cohort included 1128 participants (age 34·7±8·2 years, BMI 29·5±5·9 kg/m2, 73·2 % female). Dietary intake was assessed by 12-month food frequency questionnaire. Adiposity was measured by BMI, total percentage body fat and percentage trunk fat using dual-energy X-ray absorptiometry. Adiponectin, apelin, C-reactive protein (CRP), dipeptidyl peptidase-4 (DPP-IV), IL-1β, IL-1ra, IL-6, IL-18, leptin, lipocalin, monocyte chemo-attractant protein-1 (MCP-1), resistin, secreted frizzled protein 4 (SFRP-4), SFRP-5, TNF-α and visfatin were assayed with multiplex kits or ELISA. Joint multivariate associations between diet, adiposity and adipokines were analysed using canonical correlations adjusted for age, sex, energy intake and kinship. The median (interquartile range) energy intake was 9514 (7314, 11912) kJ/d. Overall, 55 % of total intake was accounted for by carbohydrates (24 % from sugar). A total of 66 % of the shared variation between diet and adiposity, and 34 % of diet and adipokines were explained by the top canonical correlation. The diet component was most represented by sugar-sweetened beverages (SSB), fruit and vegetables. Participants consuming a diet high in SSB and low in fruits and vegetables had higher adiposity, CRP, leptin, and MCP-1, but lower SFRP-5 than participants with high fruit and vegetable and low SSB intake. In Mexican Americans, diets high in SSB but low in fruits and vegetables contribute to adiposity and a pro-inflammatory adipokine profile.
饮食、肥胖和脂肪因子在糖尿病和心血管疾病中起着重要作用;然而,有限的研究评估了饮食与多种脂肪因子之间的关系。这项横断面研究评估了墨西哥裔美国人的饮食、肥胖和脂肪因子之间的关系。该队列包括 1128 名参与者(年龄 34.7±8.2 岁,BMI 29.5±5.9kg/m2,73.2%为女性)。饮食摄入通过 12 个月的食物频率问卷进行评估。通过双能 X 射线吸收法测量身体脂肪总量、躯干脂肪百分比和身体脂肪百分比来测量肥胖程度。采用多指标试剂盒或 ELISA 检测脂联素、apelin、C 反应蛋白(CRP)、二肽基肽酶-4(DPP-IV)、白细胞介素-1β(IL-1β)、白细胞介素-1受体拮抗剂(IL-1ra)、白细胞介素-6(IL-6)、白细胞介素-18(IL-18)、瘦素、脂联素、单核细胞趋化蛋白-1(MCP-1)、抵抗素、分泌卷曲相关蛋白 4(SFRP-4)、分泌卷曲相关蛋白 5(SFRP-5)、肿瘤坏死因子-α(TNF-α)和内脂素。使用调整年龄、性别、能量摄入和亲属关系的典型相关分析来分析饮食、肥胖和脂肪因子之间的联合多变量关联。中位数(四分位距)能量摄入量为 9514(7314,11912)kJ/d。总的来说,总摄入量的 55%来自碳水化合物(24%来自糖)。饮食和肥胖之间共享变异的 66%,以及饮食和脂肪因子之间的 34%,可以用最佳典型相关来解释。饮食成分主要由含糖饮料(SSB)、水果和蔬菜组成。摄入高 SSB 低水果和蔬菜饮食的参与者肥胖程度较高,CRP、瘦素和 MCP-1 水平较高,而 SFRP-5 水平较低,而摄入高水果和蔬菜、低 SSB 饮食的参与者则相反。在墨西哥裔美国人中,高 SSB 但低水果和蔬菜的饮食会导致肥胖和促炎脂肪因子谱。
