Away-from-home foods (AFHFs) influence diet quality, a modifiable obesity risk factor, with limited generalizable evidence in Hispanic/Latino adults.
We investigated associations between AFHF intake with diet quality and overweight or obesity among US Hispanic/Latino adults.
Cross-sectional baseline (2008-2011) analyses included adults (n = 16,045) aged 18-74 y in the national Hispanic Community Health Study/Study of Latinos. Participants self-reported AFHF consumption frequency from 10 different settings and dietary intake (2-d 24-h recall). The Alternate Healthy Eating Index-2010 (AHEI-2010) was used to measure diet quality; higher scores indicated a healthier diet and scores were categorized into tertiles. WHO classifications categorized overweight [body mass index (BMI; kg/m2): 25.0-29.9] and obesity (BMI ≥30). Multivariate-adjusted associations of AFHF frequency or type with AHEI-2010, overweight, or obesity were assessed by using complex survey logistic regression (ORs and 95% CIs).
Almost half of participants (47.1%) reported eating AFHFs ≥5 times/wk. The mean ± SE AHEI-2010 score was 47.5 ± 0.2. More than one-third (37.2%) were classified as overweight and 39.6% classified as obese. Compared with consuming AFHFs ≥5 times/wk, consuming AFHFs <1 time/wk or 1-2 times/wk was associated with greater odds of being in higher AHEI-2010 tertiles, indicating a healthier diet [<1 time/wk-tertile 2: OR (95% CI): 1.6 (1.4, 1.9); tertile 3: 2.5 (2.1, 3.1); 1-2 times/wk-tertile 2: OR (95% CI): 1.4 (1.2, 1.6); tertile 3: 1.5 (1.2, 1.8)]. Consumption of AFHFs ≥1 time/wk from each AFHF setting, compared with consumption of any AFHFs <1 time/wk was associated with lower odds of being in higher AHEI-2010 tertiles. Increasing AFHF intake frequency was not associated with odds of overweight or obesity. Eating from on-street vendors ≥1 time/wk was associated with obesity (OR: 1.5; 95% CI: 1.1, 2.0).
Consumption of AFHFs was prevalent among Hispanic/Latino adults and was associated with poorer diet quality. Findings may help to identify dietary targets to improve diet quality and prevent obesity in US Hispanics/Latinos.
外出就餐（away-from-home foods，AFHFs）会影响饮食质量，而饮食质量是可改变的肥胖风险因素，这在西班牙裔/拉丁裔成年人中证据有限。
我们研究了美国西班牙裔/拉丁裔成年人中 AFHF 摄入量与饮食质量和超重或肥胖之间的关联。
横断面基线（2008-2011 年）分析包括全国西班牙裔社区健康研究/拉丁裔研究中年龄在 18-74 岁的 16045 名成年人。参与者自我报告了来自 10 种不同场所的 AFHF 消费频率和饮食摄入（2 天 24 小时回忆）。使用替代健康饮食指数-2010（Alternate Healthy Eating Index-2010，AHEI-2010）来衡量饮食质量；较高的分数表示更健康的饮食，分数分为三分位。世界卫生组织（World Health Organization，WHO）分类将超重[体重指数（BMI；kg/m2）：25.0-29.9]和肥胖（BMI≥30）。使用复杂调查逻辑回归（比值比（ORs）和 95%置信区间（CIs））评估 AFHF 频率或类型与 AHEI-2010、超重或肥胖之间的关联。
近一半（47.1%）的参与者报告每周至少食用 AFHFs 5 次。AHEI-2010 的平均±标准误得分为 47.5±0.2。超过三分之一（37.2%）被归类为超重，39.6%被归类为肥胖。与每周食用 AFHFs≥5 次相比，每周食用 AFHFs<1 次或 1-2 次与处于较高 AHEI-2010 三分位的几率更高相关，表明饮食更健康[<1 次/周三分位 2：OR（95%CI）：1.6（1.4，1.9）；三分位 3：2.5（2.1，3.1）；1-2 次/周三分位 2：OR（95%CI）：1.4（1.2，1.6）；三分位 3：1.5（1.2，1.8）]。与每周食用任何 AFHFs<1 次相比，每周食用 AFHFs≥1 次来自每种 AFHF 场所与处于较高 AHEI-2010 三分位的几率较低相关。增加 AFHF 摄入频率与超重或肥胖的几率无关。每周从街头小贩处进食≥1 次与肥胖有关（OR：1.5；95%CI：1.1，2.0）。
AFHFs 在西班牙裔/拉丁裔成年人中很普遍，与较差的饮食质量有关。这些发现可能有助于确定饮食目标，以改善美国西班牙裔/拉丁裔人群的饮食质量并预防肥胖。
