Trends of increasing obesity are especially pronounced among Mexican-origin women. There is little understanding of dietary patterns among U.S.- and Mexico-born Mexican-origin individuals residing in new-destination immigrant communities in the United States, especially behaviors related to obesity, such as consumption of sugar-sweetened beverages (SSB) and fast-food meals (FFM).
The study used survey data of 599 adult Mexican-origin women from the 610 women who completed the 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA), which was completed in person by trained promotora-researchers in 44 colonias near the Texas border towns of Progreso and La Feria. Data included demographic characteristics (age, education, nativity or country of birth, household income, household composition, and employment status), access to transportation, self-reported height and weight, food and nutrition assistance program participation, and consumption of SSB and FFM. Descriptive statistics were calculated by nativity (U.S.-born vs. Mexico-born); multivariable linear regression models were estimated for correlates of consumption of SSB and FFM.
There are three major findings related to nativity. First, U.S.-born women consumed more SSB and FFM than Mexican-born counterparts in the same areas of colonias. Second, in the combined sample and controlling for other population characteristics, being born in Mexico was independently associated with FFM (fewer FFM), but not with SSB. Third, in analyses stratified by nativity, FFM and SSB were associated with each other among both nativity groups. Among Mexico-born women only, age, presence of a child, or being a lone parent was significantly associated with SSB; full-time employment, being a lone parent, and SSB consumption were each independently associated with increased frequency of FFM.
Our analyses revealed differences in prevalence and correlates of SSB and FFM based on country of birth. Nativity, as a proxy for acculturation, may indicate the extent that immigrants have adopted behaviors from their new environment. However, nativity could also indicate limited accessibility to resources such as food/nutrition assistance programs, transportation, and proper documentation. Additionally, future research should focus on expanding our understanding of the meaning of nativity among individuals who share common contextual factors, but may have different life course experiences and resources needed to transition into a new place. Additional measures should be considered such as educational and occupational background, migration history, documentation status, and dietary acculturation, which may better explain heterogeneity within Hispanic subgroups.
肥胖趋势在墨西哥裔女性中尤为明显。对于居住在美国新移民社区的美籍和墨西哥籍墨西哥裔个体,人们对其饮食模式知之甚少,特别是与肥胖相关的行为,如含糖饮料(SSB)和快餐(FFM)的消费。
该研究使用了 599 名成年墨西哥裔女性的调查数据,这些女性均来自于 2009 年科利纳家庭和社区食品资源评估(C-HCFRA)的 610 名参与者,该评估由经过培训的 promotora 研究员在德克萨斯州边境城镇 Progreso 和 La Feria 附近的 44 个社区中进行了个人调查。数据包括人口统计学特征(年龄、教育程度、出生地或原籍国、家庭收入、家庭构成和就业状况)、交通可达性、自我报告的身高和体重、食品和营养援助计划的参与情况以及 SSB 和 FFM 的消费情况。按出生地(美籍 vs. 墨西哥籍)计算了描述性统计数据;使用多变量线性回归模型估计了 SSB 和 FFM 消费的相关因素。
有三个与出生地相关的主要发现。首先,在同一社区中,美籍女性比墨西哥籍女性消费更多的 SSB 和 FFM。其次,在综合样本中并控制了其他人口特征后,出生在墨西哥与 FFM(较少的 FFM)独立相关,但与 SSB 无关。第三,按出生地进行分层分析时,两组人群中 FFM 和 SSB 均相互关联。在墨西哥出生的女性中,仅年龄、有孩子或单亲家庭与 SSB 显著相关;全职工作、单亲家庭和 SSB 消费均与 FFM 消费频率增加独立相关。
我们的分析显示,基于出生地,SSB 和 FFM 的流行率和相关因素存在差异。出生地作为文化适应的代表,可能表明移民在多大程度上采用了新环境的行为。然而,出生地也可能表明他们获得食物/营养援助计划、交通和适当文件等资源的机会有限。此外,未来的研究应侧重于扩大对具有共同背景因素但可能具有不同生活经历和融入新环境所需资源的个体的出生地意义的理解。还应考虑其他措施,例如教育和职业背景、移民史、文件状况和饮食文化适应,这可能更好地解释西班牙裔亚群体中的异质性。
