自 20 世纪 90 年代实施自然保护和农村发展项目以来，老挝北部少数民族的生存状况发生了变化，这可能影响了他们的营养摄入和身体活动模式。我们在当地人最容易营养不良的雨季后半段，对14对夫妇（n = 28）进行了直接称重膳食调查和时间分配调查。我们的研究结果揭示了具有不同生存策略的两个家庭群体之间的营养差异：更加依赖轮耕林和次生林的家庭食用更多的野生植物和野猪，消耗更多的膳食纤维和维生素C；而更依赖稻田的家庭则食用更多的水生动物和盐，消耗更多的烟酸和维生素 B12。除了步行时间外，两组之间的体力活动模式没有差异。政策制定者在实施土地使用限制和移民安置项目时应考虑当地人民生计组合的变化对营养的影响。
Ethnic minorities in northern Laos have experienced changes in their subsistence portfolios since the implementation of nature conservation and rural development projects in the 1990s that may have impacted their nutritional intake and physical activity patterns. We conducted direct weighing dietary surveys and time allocation surveys of 14 couples (n = 28) in the latter half of the rainy season when local people are most vulnerable to undernutrition. Our results revealed a nutritional divergence between two household groups with different subsistence strategies: households more dependent on swidden and secondary forests ate more wild plants and wild boar, and consumed more dietary fiber and vitamin C; while households more dependent on paddy fields ate more aquatic animals and salt, and consumed more niacin and vitamin B12. Physical activity patterns did not differ between the two groups, except for time spent walking. Policy makers should consider the impact of changes in local peoples’ subsistence portfolios on nutrition when implementing land use restrictions and resettlement projects.
