In most European origin populations measures of socioeconomic position are positively associated with leisure time physical activity (LTPA), this is unclear for active commuting. In addition, these associations have scarcely been studied in ethnic minority groups, who often have a high cardiovascular disease risk. Because of the expected public health potential, we assessed the relationship of active commuting and LTPA with measures of socioeconomic position across two large ethnic minority groups in the Netherlands as compared to the European-Dutch population.
We included South Asian-Surinamese (n = 370), African-Surinamese (n = 689), and European-Dutch (n = 567) from the cross-sectional population-based SUNSET study (2001-2003). Active commuting and LTPA were assessed by the SQUASH physical activity questionnaire and calculated in square-root-transformed metabolic equivalents of task-hours/week (SQRTMET). Socioeconomic position was indicated by level of education (low/high) and occupational class (low/high). We used age-adjusted linear regression models to assess the association between physical activity and socioeconomic position.
Compared to the European-Dutch men, South Asian-Surinamese men engaged in lower levels of commuting activity and LTPA, and South Asian-Surinamese women engaged in lower levels of LTPA than their European-Dutch counterparts. Differences between the African Surinamese and the European-Dutch were small. We observed a positive gradient in active commuting activity for education in European-Dutch men (beta high education was 0.93, 95%CI: 0.45-1.40 SQRTMET higher versus low education), in South Asian-Surinamese men (beta: 0.56, 0.19-0.92), but not in African-Surinamese men (-0.06, -0.45-0.33, p for ethnicity-interaction = 0.002). In women we observed a positive gradient in active commuting activity and occupational class in European-Dutch women, and less strongly in South Asian-Surinamese and African-Surinamese women (p for ethnicity-interaction = 0.02). For LTPA and socioeconomic position, we observed no statistically significant interaction by ethnicity.
The positive gradient for socioeconomic position observed in European-Dutch was less strong, in particular for active commuting, among the South Asian-Surinamese and the African-Surinamese. This indicates that the typical focus on physical activity interventions in lower socioeconomic groups could work for European-Dutch populations, but this strategy may not be entirely applicable in the ethnic minority groups.
在大多数欧洲血统人群中，社会经济地位的衡量指标与休闲时间体力活动（LTPA）呈正相关，而这在积极通勤方面并不明确。此外，这些关联在少数族裔群体中很少被研究，这些群体通常具有较高的心血管疾病风险。由于预期具有公共卫生潜力，我们评估了两个在荷兰的大型少数族裔群体（南亚苏里南人[370 人]、非洲苏里南人[689 人]）以及欧洲裔荷兰人（567 人）的积极通勤和 LTPA 与社会经济地位之间的关系，与欧洲裔荷兰人群体进行了比较。
我们纳入了来自基于人群的 SUNSET 研究（2001-2003 年）的南亚苏里南人（n=370）、非洲苏里南人（n=689）和欧洲裔荷兰人（n=567）。积极通勤和 LTPA 通过 SQUASH 体力活动问卷评估，并以每周任务代谢当量小时的平方根转换（SQRTMET）进行计算。社会经济地位由教育水平（低/高）和职业类别（低/高）表示。我们使用年龄调整线性回归模型评估体力活动与社会经济地位之间的关联。
与欧洲裔荷兰男性相比，南亚苏里南男性的通勤活动和 LTPA 水平较低，南亚苏里南女性的 LTPA 水平也低于欧洲裔荷兰女性。非洲苏里南人与欧洲裔荷兰人之间的差异较小。我们观察到，在欧洲裔荷兰男性中，教育程度较高的人（高教育的 0.93，95%CI：0.45-1.40 SQRTMET 比低教育高）、南亚苏里南男性（β：0.56，0.19-0.92），但在非洲苏里南男性中则没有观察到积极的通勤活动（β：0.06，-0.45-0.33，p 为种族交互作用=0.002）。在女性中，我们观察到欧洲裔荷兰女性的积极通勤活动和职业类别呈正梯度，而南亚苏里南和非洲苏里南女性的梯度较弱（p 为种族交互作用=0.02）。对于 LTPA 和社会经济地位，我们没有观察到种族之间存在统计学意义上的显著交互作用。
在南亚苏里南人和非洲苏里南人中，欧洲裔荷兰人观察到的社会经济地位的正梯度（特别是对于积极通勤）较弱。这表明，在社会经济地位较低的群体中，典型的关注体力活动干预措施可能适用于欧洲裔荷兰人群体，但这种策略在少数族裔群体中可能不完全适用。
