Several interventions have targeted dyads to promote physical activity (PA) or reduce sedentary behaviour (SB), but the evidence has not been synthesised. Sixty-nine studies were identified from MEDLINE, PsycINFO, and Web of Science, and 59 were included in the main meta-analyses (providing 72 independent tests). Intervention details, type of dyadic goal, participant characteristics, and methodological quality were extracted and their impact on the overall effect size was examined. Sensitivity analyses tested effect robustness to (a) the effects of other statistically significant moderators; (b) outliers; (c) data included for participants who were not the main target of the intervention. Dyadic interventions had a small positive, highly heterogeneous, effect on PA g = .203, 95% CI [0.123–0.282], compared to comparison conditions including equivalent interventions targeting individuals. Shared target-oriented goals (where both dyad members hold the same PA goal for the main target of the intervention) and peer/friend dyads were associated with larger effect sizes across most analyses. Dyadic interventions produced a small homogeneous reduction in SB. Given dyadic interventions promote PA over-and-above equivalent interventions targeting individuals, these interventions should be more widespread. However, moderating factors such as the types of PA goal and dyad need to be considered to maximise effects.

有几项干预措施针对双性恋，以促进体力活动（PA）或减少久坐行为（SB），但证据尚未综合。从MEDLINE，PsycINFO和Web of Science中鉴定出69项研究，其中59项纳入主要的荟萃分析（提供72项独立测试）。提取了干预细节，二进目标的类型，参与者的特征和方法学质量，并考察了它们对总体效果大小的影响。敏感性分析测试了对以下各项的影响稳健性：（a）其他具有统计学意义的主持人的影响；（b）离群值；（c）包括不是干预目标的参与者的数据。二进位干预对PA g的 积极作用很小，高度异质= .203，95％CI [0.123–0.282]，而比较条件包括针对个人的等效干预措施。在大多数分析中，共有目标导向的目标（两个dyad成员对干预的主要目标持有相同的PA目标）和同伴/朋友dyad与更大的效应量相关。通过二元干预，SB的均匀减少量很小。鉴于二元干预可以促进针对个人的PA超越同等干预，因此这些干预应更加广泛。但是，需要考虑诸如PA目标和对偶类型的调节因素，以使效果最大化。
