Determine intake of fruits, vegetables and traditional foods (TF), availability of foods, and attitudes towards increasing their consumption.
Establish community baseline through a cross-sectional sample of residents who were weighed, measured and interviewed. Village stores were surveyed for food availability, price and quality.
Eighty-eight respondents self-identified as the household member primarily responsible for food shopping and cooking were surveyed in 3 Western Alaska Native villages using a food frequency questionnaire, and village stores were evaluated using food environment surveys.
Overweight (BMI[kg/m(2)] > 25) was present in 68% of participants. Fruit and vegetable intake (3.3 median servings/day) was low in comparison to recommended intakes of 5-9 servings/d. Seventy-two per cent were eating less than 5 servings/d of fruits and vegetables combined. Thirty-four per cent of respondents were trying to eat more vegetables; 41% were trying to eat more fruits. The median number of servings of TF was 3.2/d (mean 4.3/d). Seventy-seven per cent of respondents reported that they ate enough TF.
Recommendations to continue use of TF and increase intake of fruits and vegetables are consistent with local attitudes. Our findings indicate that increasing the availability of fruits and vegetables would be well received. Information from this study provides a basis for nutrition education and food supplement programs that is responsive to the needs and perceptions of the residents. Continued TF intake and increased fruit and vegetable intake have the potential to benefit the health of rural residents.
确定水果、蔬菜和传统食物（TF）的摄入量、食物可及性以及对增加其消费量的态度。
通过对居民进行称重、测量和访谈的横断面样本建立社区基线。对乡村商店的食物可及性、价格和质量进行调查。
在阿拉斯加西部的3个原住民村庄，使用食物频率问卷对88名自认为主要负责食品采购和烹饪的家庭成员进行了调查，并使用食物环境调查对乡村商店进行了评估。
68%的参与者超重（体重指数[kg/m²] > 25）。与推荐摄入量5 - 9份/天相比，水果和蔬菜摄入量较低（中位数为3.3份/天）。72%的人每天摄入的水果和蔬菜总量少于5份。34%的受访者试图多吃蔬菜；41%的受访者试图多吃水果。TF的中位数摄入量为3.2份/天（平均4.3份/天）。77%的受访者表示他们摄入了足够的TF。
继续食用TF并增加水果和蔬菜摄入量的建议与当地态度一致。我们的研究结果表明，增加水果和蔬菜的可及性会受到欢迎。本研究所得信息为营养教育和食物补充计划提供了依据，该计划能满足居民的需求和认知。持续摄入TF以及增加水果和蔬菜摄入量有可能使农村居民受益。
