BACKGROUND
Diet and physical activity lifestyle behaviors are modifiable risk factors for type 2 diabetes and are shaped by culture, potentially influencing diabetes health disparities.
OBJECTIVES
We examined whether ethnic identity-the strength of attachment to one's ethnic group, and a long-standing focus of psychological research-could help account for variations in lifestyle behaviors within a diverse population at high risk for chronic disease.
METHODS
Using data from the Gestational Diabetes' Effects on Moms trial, this US-based cross-sectional study included 1463 pregnant women (74% from minority ethnic/racial groups; 46% born outside the US) with gestational diabetes (GDM), a common pregnancy complication conferring high risk for type 2 diabetes after delivery. Mixed linear regression models examined whether ethnic identity is associated with lifestyle behaviors after adjusting for demographic, clinical, and acculturative characteristics (e.g., nativity and length of residence in the US).
RESULTS
In the overall sample, a one-unit increase in ethnic identity score was significantly associated with 3% greater fiber intake, 4% greater fruit/vegetable intake, 11% greater total activity, and 11% greater walking (p values < 0.01). Within ethnic/racial groups, a one-unit increase in ethnic identity score was significantly associated with 17% greater fiber intake among Filipina women; 5% lower total caloric intake among non-Hispanic White women; and 40% greater total activity, 35% greater walking, and 8% greater total caloric intake among Latina women (p values ≤ 0.03).
CONCLUSION
Results from this large study suggest that ethnic group attachment is associated with some lifestyle behaviors, independent of acculturation indicators, among young women with GDM who are at high risk for type 2 diabetes. Stronger ethnic identity may promote certain choices known to be associated with reduced risk of type 2 diabetes. Prospective research is needed to clarify the temporal nature of associations between ethnic identity and modifiable diabetes risk factors.
背景
饮食和身体活动的生活方式行为是2型糖尿病的可改变风险因素，且受文化影响，这可能会影响糖尿病健康差异。
目的
我们研究了族群认同（即对自己族群的归属感，这是心理学研究长期关注的重点）是否有助于解释高危慢性病多样化人群中生活方式行为的差异。
方法
利用妊娠期糖尿病对母亲影响试验的数据，这项美国横断面研究纳入了1463名患有妊娠期糖尿病（GDM）的孕妇（74%来自少数族裔/种族群体；46%在美国境外出生），妊娠期糖尿病是一种常见的妊娠并发症，会使产后患2型糖尿病的风险增加。混合线性回归模型在调整了人口统计学、临床和文化适应特征（如出生地和在美国的居住时长）后，研究了族群认同是否与生活方式行为相关。
结果
在总体样本中，族群认同得分每增加一个单位，膳食纤维摄入量显著增加3%，水果/蔬菜摄入量显著增加4%，总活动量显著增加11%，步行量显著增加11%（p值<0.01）。在族裔/种族群体中，族群认同得分每增加一个单位，菲律宾女性的膳食纤维摄入量显著增加17%；非西班牙裔白人女性的总热量摄入量降低5%；拉丁裔女性的总活动量显著增加40%，步行量显著增加35%，总热量摄入量增加8%（p值≤0.03）。
结论
这项大型研究的结果表明，在患有妊娠期糖尿病且有2型糖尿病高风险的年轻女性中，族群归属感与某些生活方式行为相关，与文化适应指标无关。更强的族群认同可能会促进某些已知与降低2型糖尿病风险相关的选择。需要进行前瞻性研究来阐明族群认同与可改变的糖尿病风险因素之间关联的时间性质。
