Given its origins in high-income countries, the field of physical activity and public health research and promotion has broadly followed a choice-based model. However, a substantial amount of the physical activity occurring routinely in many settings, particularly in low- and middle-income countries (LMICs), is the result of economic necessity and is not due to true, free choices. We propose the “necessity- versus choice-based physical activity models” framework as a conceptual tool to ground physical activity and public health research and promotion efforts in LMICs, helping ensurethat these efforts are relevant, ethical, responsive, and respectful to local contexts. Identifying ways to ensure that LMIC populations can maintain high levels of active transport while increasing opportunities for active leisure must be prioritized. To promote equity, physical activity research, programs, and policies in LMICs must focus on improving the conditions under which necessity-driven physical activity occurs for a vast majority of the population.

当搬家是唯一选择时：中低收入国家理解和促进体育活动的必要性与选择的作用

鉴于其起源于高收入国家，体育活动和公共卫生研究与推广领域大体遵循基于选择的模式。然而，在许多环境中，特别是在低收入和中等收入国家 (LMIC)，例行进行的大量身体活动是经济需要的结果，而不是真正的自由选择的结果。我们提出“基于必要性与基于选择的身体活动模型”框架作为概念工具，为中低收入国家的身体活动和公共卫生研究和推广工作奠定基础，帮助确保这些努力具有相关性、道德性、响应性和尊重当地环境。必须优先考虑如何确保中低收入国家人群能够保持高水平的主动交通，同时增加主动休闲的机会。为了促进公平，中低收入国家的体育活动研究、计划和政策必须侧重于改善绝大多数人口进行必要性体育活动的条件。
