To assess the reported baseline dietary intake of Hispanic and non-Hispanic white breast cancer survivors in the Women's Healthy Eating and Living study, a randomized plant-based dietary intervention clinical trial.
Dietary data from 4 days repeated 24-hour recalls within 3 weeks included daily total intake of energy, protein, carbohydrates, cholesterol, total fat, monounsaturated fat, saturated fat, polyunsaturated fat, fruit/vegetable servings, carotenoids, alcohol, caffeine, and percentage of energy from protein, carbohydrates, alcohol, and fats.
One hundred sixty-five Hispanic breast cancer survivors age-matched to 165 non-Hispanic white breast cancer survivors diagnosed with Stage I, II, or IIIA primary operable breast cancer.
Two-sample t tests and Wilcoxon rank sum tests to compare dietary intake, and logistic and ordinal logistic regression analyses to examine the association between ethnicity, alcohol, and lycopene consumption, while controlling for place of birth, education, body mass index, and time since diagnosis.
Hispanics were more likely to be foreign-born (P<0.001), less educated (P<0.0001) and to consume higher amounts of lycopene (P=0.029), while non-Hispanic whites were more likely to consume alcohol (P=0.001). However, no differences were observed in the average amounts of alcohol consumed or total percents of energy from alcohol. Both groups consumed more than five servings of fruits and vegetables daily. Being Hispanic remained a significant predictor of lower alcohol use (P=0.004) and higher lycopene consumption (P=0.005) after controlling for place of birth, education, body mass index, and time since diagnosis.
There are more similarities than differences in the dietary intake of Hispanic and non-Hispanic white breast cancer survivors in the Women's Healthy Eating and Living study. Further analysis is needed to determine if higher lycopene consumption shown among the Hispanic participants will translate to greater protection against breast cancer recurrence or increased survival.
在“女性健康饮食与生活”研究中评估西班牙裔和非西班牙裔白人乳腺癌幸存者报告的基线饮食摄入量，该研究是一项随机的以植物性饮食为主的干预临床试验。
在3周内进行4次重复的24小时饮食回忆所获得的饮食数据，包括每日能量、蛋白质、碳水化合物、胆固醇、总脂肪、单不饱和脂肪、饱和脂肪、多不饱和脂肪、水果/蔬菜份数、类胡萝卜素、酒精、咖啡因的总摄入量，以及蛋白质、碳水化合物、酒精和脂肪提供的能量百分比。
165名西班牙裔乳腺癌幸存者，年龄与165名诊断为I期、II期或IIIA期原发性可手术乳腺癌的非西班牙裔白人乳腺癌幸存者相匹配。
采用两样本t检验和Wilcoxon秩和检验比较饮食摄入量，并采用逻辑回归和有序逻辑回归分析，在控制出生地点、教育程度、体重指数和确诊时间的同时，研究种族、酒精和番茄红素摄入量之间的关联。
西班牙裔更有可能出生在国外（P<0.001），受教育程度较低（P<0.0001），番茄红素摄入量较高（P=0.029），而非西班牙裔白人更有可能饮酒（P=0.001）。然而，两组在酒精平均摄入量或酒精提供的能量总百分比方面没有差异。两组每天食用的水果和蔬菜份数均超过五份。在控制出生地点、教育程度、体重指数和确诊时间后，西班牙裔仍然是饮酒量较低（P=0.004）和番茄红素摄入量较高（P=0.005）的显著预测因素。
在“女性健康饮食与生活”研究中，西班牙裔和非西班牙裔白人乳腺癌幸存者的饮食摄入量相似之处多于不同之处。需要进一步分析以确定西班牙裔参与者中较高的番茄红素摄入量是否会转化为对乳腺癌复发的更大保护或生存率的提高。
