Ethnic disparity in dietary intakes of eicosenoic fatty acid and DPA in the LSC and VSCa
| Cohort | Nutrient (U/day) | NHWs | Hispanics | P-value |
|---|---|---|---|---|
| LSC | n=1,502 | n=327 | ||
| Eicosenoic fatty acid (mg) | 173.3 (120.1–250.1) | 169.3 (120.1–260.1) | 0.41 | |
| DPA (mg) | 14.3 (10.1–30.1) | 8.0 (10.1–30.1) | 1.6×10-5 | |
| VSC | n=344 | n=164 | ||
| Eicosenoic fatty acid (mg) | 212.9 (140.1–320.1) | 200.7 (130.1–305.0) | 0.0016 | |
| DPA (mg) | 12.1 (10.1–30.1) | 8.7 (10.1–20.1) | 0.0092 |
Notes: DPA, docosapentaenoic fatty acid 22:5n3.
Age, sex, smoking history (smoking status and pack-years), BMI, educational level, and total calorie intake were adjusted in multivariate linear regression with natural log transformed nutrients as the outcome. Data are shown as geometric means with lower and upper quartiles. Total calorie intake was 1,890.2±716.1 versus 1,796.4±619.1 for Hispanics and NHWs (Wilcoxon test, P=0.067) in the LSC and 2,184.3±1,247.6 versus 2,001.3±793.4 for Hispanics and NHWs (Wilcoxon test, P=0.65) in the VSC.
