背景：关于社会支持和闲暇时间体力活动(LTPA)之间关系的证据很少，而且大多基于横断面数据，不同类型的社会支持被归结为单一指数。这项研究的目的是调查来自最亲近的人的社会支持是否与LTPA相关。方法：对参与英国白厅II研究的5395名成年人(平均年龄55.7岁，3864名男性)进行前瞻性队列研究。在1997-99年度，使用亲密者问卷对信任/情感支持和实际支持进行了基线评估。在2002-04年的基线和随访中评估LTPA。基线协变量包括社会人口学、自评健康、长期疾病、身体功能和常见精神障碍。结果：在那些报告了基线时LTPA推荐水平的参与者中，那些经历了高度信任/情感支持的人更有可能在随访时报告推荐的LTPA水平[优势比(OR)：1.39，95%可信区间(CI)：1.12-1.70，在调整了基线协变量的模型中]。在那些在基线时没有达到LTPA推荐目标的参与者中，高度信任/情感支持与活动水平的改善无关。高实际支持与维持(OR：1.34，95%CI：1.10-1.63)和改善(OR：1.25，95%CI：1.02-1.53)LTPA水平相关。结论：这些发现表明，来自最亲近的人的情感和实际支持可能有助于个人维持推荐的LTPA水平。实际支持也预示着向更积极的生活方式转变。
Background: Evidence on the association between social support and leisure time physical activity (LTPA) is scarce and mostly based on cross-sectional data with different types of social support collapsed into a single index. The aim of this study was to investigate whether social support from the closest person was associated with LTPA. Methods: Prospective cohort study of 5395 adults (mean age 55.7 years, 3864 men) participating in the British Whitehall II study. Confiding/emotional support and practical support were assessed at baseline in 1997-99 using the Close Persons Questionnaire. LTPA was assessed at baseline and follow-up in (2002-04). Baseline covariates included socio-demographics, self-rated health, long-standing illnesses, physical functioning and common mental disorders. Results: Among participants who reported recommended levels of LTPA at baseline, those who experienced high confiding/emotional support were more likely to report recommended levels of LTPA at follow-up [odds ratio (OR): 1.39, 95% confidence interval (CI): 1.12-1.70 in a model adjusted for baseline covariates]. Among those participants who did not meet the recommended target of LTPA at baseline, high confiding/emotional support was not associated with improvement in activity levels. High practical support was associated with both maintaining (OR: 1.34, 95% CI: 1.10-1.63) and improving (OR: 1.25, 95% CI: 1.02-1.53) LTPA levels. Conclusion: These findings suggest that emotional and practical support from the closest person may help the individual to maintain the recommended level of LTPA. Practical support also predicted a change towards a more active lifestyle.
