The present study was conducted to determine the impact of a community-based intervention on the nutritional behaviour of a representative sample of Iranian adults.
The Isfahan Healthy Heart Programme (IHHP), a six-year, action-oriented, integrated community-based study aimed at health promotion through the reduction of CVD risk factors, targeted the whole population living in two intervention cities, and compared outcomes with the population of a non-intervention city considered as reference. Dietary interventions were performed as educational, environmental and/or legislative strategies. A global dietary index (GDI) was calculated representing the general dietary behaviour. In addition, two consumption indices were calculated for specific food groups, i.e. meat products and major sources of fat. Univariate AVOVA was conducted to evaluate the impact of the intervention on dietary behaviours.
Isfahan and Najaf-Abad (intervention cities) and Arak (reference city), central Iran.
The baseline survey was conducted among 12514 randomly selected adults aged > or =19 years in both intervention and reference areas. The survey was repeated annually among about 5000 persons (2002-2005) in the intervention and reference communities.
According to significant year x group interactions in mean fat consumption index (FCI) and meat consumption index (MCI) in the total population, a significant improvement in FCI and MCI was found in the intervention areas v. the reference area (P < 0.001). In addition, the GDI improved significantly in the intervention areas v. the reference area (P < 0.001).
The IHHP interventions were effective in improving dietary behaviours at the population level. The highest effectiveness was documented in the change in the type of fat consumed. Such simple and integrated interventions can be adopted in other developing countries with limited financial resources.
本研究旨在确定一项基于社区的干预措施对伊朗成年代表性样本营养行为的影响。
伊斯法罕健康心脏计划（IHHP）是一项为期六年、以行动为导向的综合性社区研究，旨在通过降低心血管疾病风险因素来促进健康。该计划针对两个干预城市的全体居民，并与作为对照的非干预城市居民的结果进行比较。饮食干预通过教育、环境和/或立法策略实施。计算了一个全球饮食指数（GDI）以代表总体饮食行为。此外，还针对特定食物组计算了两个消费指数，即肉类产品和主要脂肪来源。采用单因素方差分析来评估干预对饮食行为的影响。
伊朗中部的伊斯法罕和纳贾夫 - 阿巴德（干预城市）以及阿拉克（对照城市）。
在干预和对照地区随机选取了12514名年龄≥19岁的成年人进行基线调查。在干预和对照社区中，每年对约5000人（2002 - 2005年）进行重复调查。
根据总体人群中平均脂肪消费指数（FCI）和肉类消费指数（MCI）的显著年份×组交互作用，发现干预地区的FCI和MCI相对于对照地区有显著改善（P < 0.001）。此外，干预地区的GDI相对于对照地区也有显著改善（P < 0.001）。
IHHP干预措施在改善人群饮食行为方面是有效的。在脂肪消费类型的变化方面记录到了最高的有效性。这种简单且综合的干预措施可在其他财政资源有限的发展中国家采用。
