很少有人研究过针对年轻人的心理社会营养干预措施的效果,水果和蔬菜(FV)消费量低的人群。这项研究调查了具有心理社会内容的营养干预对改善年轻成人FV摄入量的影响。
本注册系统评价以系统评价和荟萃分析的首选报告项目为指导。
在CINAHL上进行搜索,Embase,MedlinePubMed,Ovid-Medline,PsychInfo,和WebofScience确定了4,113条记录。提取24项随机对照试验。18项研究发现,水果和/或蔬菜摄入量存在显著的组间差异。低收入和种族亚群体的年轻人代表性不足。从心理社会干预内容中出现了一种类型学作为组织框架。干预是预期的,社会参与,混合(预期和社会参与),或基于曝光。研究还报告了意想不到的后果。
显著的组间差异主要由预期报告,社会参与,或混合干预措施,通过详细的规划与年轻人的发展需求保持一致,目标设定任务,和/或解决社会规范。差异不明显的干预措施缺乏参与和充分的接触。
人口包容性研究对于解决社会经济地位的饮食差异至关重要。强调内容而不是理论或治疗策略的干预类型扩大了跨学科合作的机会。需要进行更多的研究来减轻意外后果(回旋镖效应),其中干预后FV摄入量减少或参与者参与旨在增加FV摄入量的活动。
Few have examined the effects of psychosocial nutrition interventions targeting young adults, a population with low fruit and vegetable (FV) consumption. This study investigated the impact of nutrition interventions with psychosocial content on improving young adult FV intake.
This registered systematic
review was guided by the Preferred Reported Items for Systematic Reviews and Meta-Analyses.
Searches on CINAHL, Embase, Medline PubMed, Ovid-Medline, PsychInfo, and Web of Science identified 4,113 records. Twenty-four randomized controlled trials were extracted. Eighteen studies found significant between-group differences in fruit and/or vegetable intake. Young adults with low income and racial-ethnic subgroups were underrepresented. A typology emerged as an organizing framework from the psychosocial intervention content. Interventions were anticipatory, socially engaged, a hybrid (anticipatory and socially engaged), or exposure-based. Studies also reported unintended consequences.
Significant between-group differences were mostly reported by anticipatory, socially engaged, or hybrid interventions, aligning with young adult developmental needs through detailed planning, goal-setting tasks, and/or addressing social norms. Interventions with insignificant differences lacked engagement and adequate exposure.
Demographically inclusive studies are imperative in addressing dietary disparities by socioeconomic status. A typology of interventions emphasizing content rather than theories or treatment strategies widens opportunities for interdisciplinary collaboration. More research is needed to mitigate unintended consequences (boomerang effects) in which FV intake decreased postintervention or participants disengaged in activities intended to increase FV intake.
