The objective of this study was to investigate potential factors related to Pacific children's moderate-to-vigorous physical activity (MVPA). A total of 393 Pacific children aged 6 years and their mothers were invited to participate. Participants wore accelerometers over 8 days; height, weight, and waist circumference were measured, and mothers reported on individual, social, and perceived environmental factors. Generalized estimation equation models were used to identify associates of children's daily MVPA. In all, 135 children and 91 mothers were included in analyses. Children spent 24% of time in MVPA; 99% of days had ≥60 minutes of MVPA. Higher maternal MVPA, male sex, longer sunlight hours, and rain-free days were associated with children's MVPA. Approaches for improving activity in Pacific children may be most efficacious if strategies for inclement weather and the encouragement of activity in mothers and, in particular, their daughters are included. Also, 60 minutes of daily MVPA may be insufficient to protect Pacific children from increased body size.
本研究旨在探讨与太平洋儿童中等到剧烈身体活动（MVPA）相关的潜在因素。共邀请了 393 名 6 岁的太平洋儿童及其母亲参与。参与者佩戴加速度计 8 天；测量了身高、体重和腰围，母亲报告了个人、社会和感知环境因素。广义估计方程模型用于确定儿童日常 MVPA 的关联因素。共有 135 名儿童和 91 名母亲纳入分析。儿童每天有 24%的时间进行 MVPA；99%的天数有≥60 分钟的 MVPA。较高的母亲 MVPA、男性、较长的阳光时间和无雨天数与儿童的 MVPA 相关。如果在包括恶劣天气在内的策略和鼓励母亲活动，特别是鼓励母亲女儿活动方面采取措施，可能会更有效地提高太平洋儿童的活动水平。此外，每天 60 分钟的 MVPA 可能不足以防止太平洋儿童的体型增加。
