With each successive generation in the United States, Mexican-origin families lose their initial dietary advantages. Focusing on children’s diets, we ask whether greater socioeconomic status (SES) can help buffer Mexican-origin children in immigrant families from negative dietary acculturation or whether it exacerbates these dietary risks. Pooling data from the 1999 to 2009 waves of the continuous National Health and Nutrition Examination Survey, we test whether the association between generational status and Mexican-origin children’s nutrition varies by the family’s SES. When predicting children’s overall dietary quality using the Healthy Eating Index (2010) and predicting unhealthy dietary patterns, we find stronger evidence of segmented assimilation, whereby greater family average SES is associated with better diets across generations of Mexican-origin children. High-status Mexican-origin parents appear able to buffer their children against generational dietary declines documented in the acculturation literature.
Past research on immigrant health frequently finds that the duration of time lived in the United States is associated with the erosion of immigrants' health advantages. However, the timing of U.S. migration during the life course is rarely explored. We draw from developmental and sociological perspectives to theorize how migration during childhood may be related to healthy eating among adult immigrants from Mexico. We test these ideas with a mechanism-based age-period-cohort model to disentangle age, age at arrival, and duration of residence. Results show that immigrants who arrived during preschool ages (2-5 years) and school ages (6-11 years) have less healthy diets than adult arrivals (25+ years). After accounting for age at arrival, duration of residence is positively related to healthy eating. Overall, the findings highlight the need to focus more research and policy interventions on child immigrants, who may be particularly susceptible to adopting unhealthy American behaviors during sensitive periods of childhood.
Health and immigration researchers often implicate dietary acculturation in explanations of Mexican children of immigrants’ weight gain after moving to the U.S., but rarely explore how diet is shaped by immigrants’ structural incorporation. We used data from the 1999/00–2009/10 National Health and Nutrition Examination Survey to assess how indicators of Mexican-origin children’s acculturation and structural incorporation influence two outcomes: how healthy and how “Americanized” children’s diets are. Indicators of acculturation were strongly associated with more Americanized and less healthy diets. However, structural incorporation indicators were mostly unrelated to diet outcomes net of acculturation. An exception was that parental education was positively associated with consuming a healthy diet. Finally, children of natives consumed more Americanized, unhealthy diets than children of immigrants and these differences were largely explained by differences in the acculturation. Children of natives would have consumed an even less healthy diet were it not for their higher levels of parental education. Overall, the results suggest that the process of adapting to the U.S. life style is associated with the loss of cultural culinary preferences and less healthy eating behaviors despite improvements in socioeconomic status.
Background This study introduces a flexible indicator of dietary acculturation that measures immigrants’ eating behavior relative to U.S.-born persons. Methods Using 24-hour dietary recall data from the continuous National Health and Nutrition Examination Survey pooled across multiple years from 1999/00 through 2009/10, we developed and tested the validity of the “Food Similarity Index” (FSI), which indicates the similarity of the foods consumed by individuals to the foods most commonly consumed by same-aged U.S-born persons of all racial/ethnic groups. We demonstrate its utility here for children and adults of four racial-ethnic groups. Results FSI was positively associated with the consumption of common American foods and negatively associated with eating Hispanic and Asian foods. In addition, FSI was associated with generational status among all racial/ethnic groups and duration of U.S. residence among Hispanics. FSI was also negatively associated with the Healthy Eating Index 2010. Discussion The FSI enables researchers to compare immigrants’ dietary patterns over generations and across groups. It can be used to study how dietary acculturation shapes health risk factors and diseases.
Immigrants’ health (dis)advantages are increasingly recognized as not being uniform, leading to calls for studies investigating whether immigrant health outcomes are dependent on factors that exacerbate health risks. We answer this call, considering an outcome with competing evidence about immigrants’ vulnerability versus risk: childhood obesity. More specifically, we investigate obesity among three generations of Mexican-origin youth relative to one another and to U.S.-born whites. We posit that risk is dependent on the intersection of generational status, gender, and age, which all influence exposure to U.S. society and weight concerns. Analyses of National Health and Nutrition Examination Studies (NHANES) data suggest that accounting for ethnicity and generation alone misses considerable gender and age heterogeneity in childhood obesity among Mexican-origin and white youth. For example, second-generation boys are vulnerable to obesity, but the odds of obesity for first-generation girls are low and on par with those of whites. Findings also indicate that age moderates ethnic/generational differences in obesity among boys but not among girls. Overall, ethnic/generational patterns of childhood obesity do not conform to a “one size fits all” theory of immigrant health (dis)advantage, leading us to join calls for more research considering how immigrants’ characteristics and contexts differentially shape vulnerability to disease and death.
