ABSTRACT

The purpose of this study is to investigate socioeconomic inequality in fruit and vegetable (F&V) intake and contributing factors. Data of 9981 participants from the recruitment phase of Ravansar Non-Communicable Diseases (RaNCD) cohort study were included in the final analysis. The concentration index was calculated to measure the inequality. The prevalence of adequate F&V intake was 55.8% and concentration index was 0.178, indicating that more people in the higher SES group are consuming enough F&V. Place of residence, followed by SES, had the greatest contribution to F&V intake inequality in the west of Iran. It is suggested that villagers and the poor be the target group for interventions to increase fruit and vegetable access.

摘要

本研究的目的是调查水果和蔬菜 (F&V) 摄入量方面的社会经济不平等及其影响因素。来自 Ravansar 非传染性疾病 (RaNCD) 队列研究招募阶段的 9981 名参与者的数据被纳入最终分析。计算集中指数以衡量不平等。F&V 摄入量充足的流行率为 55.8%，浓度指数为 0.178，表明较高 SES 组中更多的人消费了足够的 F&V。居住地，其次是 SES，对伊朗西部的 F&V 摄入不平等的贡献最大。建议将村民和穷人作为干预措施的目标群体，以增加水果和蔬菜的获取。
