在规划干预措施以应对资源匮乏地区的微量营养素缺乏时，了解并考虑食物和营养素摄入量的季节性变化非常重要。本研究的目的是量化布基纳法索农村地区幼儿及其母亲在青黄不接和收获后 (PH) 季节的食物和营养素摄入量，并评估微量营养素摄入量是否充足。我们通过 24 小时回忆来量化布基纳法索西部两个省份 480 名 36-59 个月的儿童及其母亲的代表性样本的食物摄入量。我们计算了十种微量营养素的正常摄入量的充足概率 (PA) 和总体平均 PA (MPA)。营养摄入量和 PA 的季节性变化分别通过混合线性回归和非参数检验进行评估。女性或儿童的能量摄入量在季节之间没有显着差异，尽管女性在PH季节的摄入量略高。大多数微量营养素的摄入量在PH季节显着较高，但维生素A的摄入量较低，维生素B-12和锌的摄入量在不同季节相似。 MPA 随季节显着增加，女性从 0.26 增加到 0.37，儿童从 0.43 增加到 0.52。钙、维生素 C、叶酸和维生素 B-12 的 PA 含量非常低。主粮和蔬菜是微量营养素的主要来源，但摄入量不足以满足大多数受试者的营养需求。需要采取以食物为基础的策略来增加布基纳法索妇女和儿童的微量营养素摄入量。
It is important to understand and account for seasonal variation in food and nutrient intakes when planning interventions to combat micronutrient deficiencies in resource-poor settings. The objective of the present study was to quantify food and nutrient intakes and assess the adequacy of micronutrient intakes among young children and their mothers during the lean and post-harvest (PH) seasons in rural Burkina Faso. We quantified food intakes by 24-h recall in a representative sample of 480 children aged 36-59 months and their mothers in two provinces in Western Burkina Faso. We calculated the probability of adequacy (PA) of usual intakes of ten micronutrients and an overall mean PA (MPA). Seasonal changes in nutrient intakes and PA were assessed by mixed linear regression and non-parametric tests, respectively. Energy intakes did not differ significantly between seasons for women or children, although the women's intakes were slightly higher in the PH season. Most of the micronutrient intakes were significantly higher in the PH season, with the exception of vitamin A which was lower and vitamin B-12 and Zn which were similar across seasons. MPA increased significantly across seasons, from 0.26 to 0.37 for women and from 0.43 to 0.52 for children. PA of Ca, vitamin C, folate and vitamin B-12 were very low. Staple grains and vegetables were major sources of micronutrients but intakes were not sufficient to meet nutrient needs for the majority of the subjects. Food-based strategies are needed to increase micronutrient intakes of women and children in Burkina Faso.
