This article describes data collected to analyze consumer behaviors in vulnerable populations by examining key access constraints to nutritious foods among households of differing socio-economic status in urban and peri‑urban areas of Nairobi, Kenya. The key variables studied include wealth status, food security, and dietary behavior indicators at individual and household level. Household food insecurity access scale (HFIAS), livelihood coping strategies (LCS), food expenditure share (FES), food consumption score (FCS), household dietary diversity score (HDDS), minimum dietary diversity-women(MDD-W), and child dietary diversity score (CDDS) indicators were used to measure food security. Household assets were used to develop an asset-based wealth index that grouped the study sample population into five wealth quantiles, while income levels were used to estimate FES. The hypothesis that guided the cross-sectional survey conducted to generate these data is that vulnerability to food insecurity and poverty are important drivers of food choice that influence household and individual dietary behavior. Data from this study was thus used to assess direction and strength of association between; household food insecurity, wealth status, women, children, and household dietary behavior in both urban and peri‑urban populations sampled.
本文介绍了所收集的数据，这些数据是通过研究肯尼亚内罗毕市区和城郊地区不同社会经济地位家庭获取营养食品的关键限制因素，来分析弱势群体中的消费者行为。所研究的关键变量包括个人和家庭层面的财富状况、粮食安全及饮食行为指标。使用家庭粮食不安全获取量表（HFIAS）、生计应对策略（LCS）、食品支出份额（FES）、食物消费得分（FCS）、家庭饮食多样性得分（HDDS）、最低饮食多样性-女性（MDD-W）以及儿童饮食多样性得分（CDDS）指标来衡量粮食安全。家庭资产用于构建基于资产的财富指数，该指数将研究样本人群分为五个财富五分位数，同时使用收入水平来估算食品支出份额。指导此次横断面调查以生成这些数据的假设是，粮食不安全和贫困的脆弱性是影响家庭和个人饮食行为的食物选择的重要驱动因素。因此，本研究的数据用于评估抽样的城市和城郊人群中，家庭粮食不安全、财富状况、女性、儿童与家庭饮食行为之间关联的方向和强度。
