■种族,文化背景,和地理位置在美国西班牙裔/拉丁裔人口中存在显着差异。这些变化可以极大地定义饮食及其与心脏代谢疾病的关系,从而影响结果的普遍性。
■我们旨在研究西班牙裔/拉丁裔成年人的营养食物模式(NBFPs)及其与心脏代谢危险因素(血脂异常,高血压,肥胖,糖尿病)在2项美国基于人群的研究中,采用不同的抽样策略。
■数据来自2007-2012年国家健康和营养调查(NHANES)(n=3605)和2007-2011年西班牙裔社区健康调查/研究拉丁美洲人(HCHS/SOL,n=14,416)。NBFP是通过对24小时饮食召回估算的营养摄入量数据进行因子分析得出的,并使用这些营养素突出的普通食物进行解释。NBFP(五分位数)和心脏代谢危险因素之间的横断面关联,由临床措施和自我报告定义,使用调查加权多变量调整逻辑模型进行估计,多重测试的会计。
■在两项研究中都确定了五个NBFP:1)肉类,2)谷物/豆类,3)水果/蔬菜,4)乳制品,和5)脂肪/油。与心脏代谢危险因素的关联因NBFP和研究而异。在HCHS/SOL中,与第3位(中等摄入量)第5位的人群相比,第5位的人群患糖尿病的几率较低(比值比[OR]:0.73;95%置信区间[CI]:0.58,0.92),而第3位(中等摄入量)第5位的人群患糖尿病的几率较高(OR:0.71;95%CI:0.55,0.93).乳制品NBFP的第四个五分之一人群患高血压的几率高于第三个五分之一人群(OR:1.31;95%CI:1.01,1.70)。在NHANES,乳制品第4位(OR:1.88;95%CI:1.10,3.24)患高血压的几率高于第3位.
■西班牙裔/拉丁裔成年人之间的饮食与疾病关系根据2项基于人群的研究而有所不同。在概括异质代表性不足人群的推论时,这些差异具有研究和实际意义。
UNASSIGNED: Ethnicity, cultural background, and geographic location differ significantly within the United States Hispanic/Latino population. These variations can greatly define diet and its relationship with cardiometabolic disease, thus influencing generalizability of results.
UNASSIGNED: We aimed to examine nutrient-based food patterns (NBFPs) of Hispanic/Latino adults and their association with cardiometabolic risk factors (dyslipidemia, hypertension, obesity, diabetes) across 2 United States population-based studies with differing sampling strategies.
UNASSIGNED: Data were collected from Mexican or other Hispanic adult participants from 2007-2012 National Health and Nutrition Examination Survey (NHANES) (n = 3605) and 2007-2011 Hispanic Community Health Survey/Study of Latinos (HCHS/SOL, n = 14,416). NBFPs were derived using factor analysis on nutrient intake data estimated from 24-h dietary recalls and interpreted using common foods in which these nutrients are prominent. Cross-sectional associations between NBFPs (quintiles) and cardiometabolic risk factors, defined by clinical measures and self-report, were estimated using survey-weighted multivariable-adjusted logistic models, accounting for multiple testing.
UNASSIGNED: Five NBFPs were identified in both studies: 1) meats, 2) grains/legumes, 3) fruits/vegetables, 4) dairy, and 5) fats/oils. Associations with cardiometabolic risk factors differed by NBFP and study. In HCHS/SOL, the odds of diabetes were lower for persons in the highest quintile of meats NBFP (odds ratio [OR]: 0.73; 95% confidence interval [CI]: 0.58, 0.92) and odds were higher for those in the lowest quintile of fruits/vegetables (OR: 0.71; 95% CI: 0.55, 0.93) compared to those in the third (moderate intake) quintile. Those in the fourth quintile of dairy NBFP had higher odds of hypertension than those in the third quintile (OR: 1.31; 95% CI: 1.01, 1.70). In NHANES, the odds of hypertension were higher for those in the fourth quintile of dairy (OR: 1.88; 95% CI: 1.10, 3.24) than those in the third quintile.
UNASSIGNED: Diet-disease relationships among Hispanic/Latino adults vary according to 2 population-based studies. These differences have research and practical implications when generalizing inferences on heterogeneous underrepresented populations.
