Using Jackson Heart Study data, we examined associations of multiple measures of perceived discrimination with health behaviours among African-Americans (AA).
The cross-sectional associations of everyday, lifetime and burden of discrimination with odds of smoking and mean differences in physical activity, dietary fat and sleep were examined among 4925 participants aged 35-84 years after adjustment for age and socioeconomic status (SES).
Men reported slightly higher levels of everyday and lifetime discrimination than women and similar levels of burden of discrimination as women. After adjustment for age and SES, everyday discrimination was associated with more smoking and a greater percentage of dietary fat in men and women (OR for smoking: 1.13, 95% CI 1.00 to 1.28 and 1.19, 95% CI 1.05 to 1.34; mean difference in dietary fat: 0.37, p<0.05 and 0.43, p<0.01, in men and women, respectively). Everyday and lifetime discrimination were associated with fewer hours of sleep in men and women (mean difference for everyday discrimination: -0.08, p<0.05 and -0.18, p<0.001, respectively; and mean difference for lifetime discrimination: -0.08, p<0.05 and -0.24, p<0.001, respectively). Burden of discrimination was associated with more smoking and fewer hours of sleep in women only.
Higher levels of perceived discrimination were associated with select health behaviours among men and women. Health behaviours offer a potential mechanism through which perceived discrimination affects health in AA.
利用杰克逊心脏研究数据，我们研究了非裔美国人（AA）中多种感知到的歧视测量指标与健康行为之间的关联。
在对年龄和社会经济地位（SES）进行调整后，对4925名年龄在35 - 84岁的参与者，研究日常、一生和歧视负担与吸烟几率以及身体活动、膳食脂肪和睡眠方面的平均差异之间的横断面关联。
男性报告的日常和一生歧视水平略高于女性，且歧视负担水平与女性相似。在对年龄和SES进行调整后，日常歧视与男性和女性吸烟更多以及膳食脂肪占比更高有关（吸烟的OR值：1.13，95%CI为1.00至1.28；女性为1.19，95%CI为1.05至1.34；男性和女性膳食脂肪的平均差异分别为0.37，p<0.05和0.43，p<0.01）。日常和一生歧视与男性和女性睡眠时间减少有关（日常歧视的平均差异分别为：-0.08，p<0.05；女性为-0.18，p<0.001；一生歧视的平均差异分别为：-0.08，p<0.05；女性为-0.24，p<0.001）。仅在女性中，歧视负担与吸烟更多和睡眠时间减少有关。
较高水平的感知到的歧视与男性和女性的特定健康行为有关。健康行为提供了一种潜在机制，通过该机制感知到的歧视影响非裔美国人的健康。
