Drug abuse is an important risk factor for the human immunodeficiency virus (HIV) among Hispanics living in the northeastern United States, and both drug abuse and HIV are associated with nutritional deficiencies. The selection of a dietary assessment method most appropriate for Hispanic adults with/without HIV infection who may be drug abusers remains unclear.
Participants were recruited into one of the three groups: HIV-infected drug abusers, HIV-noninfected drug abusers, and HIV-infected non-drug abusers. Subjects who completed two of the three dietary methods were included in cross-sectional pairwise comparisons.
The baseline data from a prospective cohort study of the role of drug abuse in HIV/acquired immunodeficiency syndrome-related weight loss.
The 286 enrolled participants completed 282 food frequency questionnaires (FFQs), 142 3-day diet records, and 270 24-hour recalls. Energy-adjusted and deattenuated correlations between the FFQ and 3-day diet records ranged from 0.11 (carbohydrate) to 0.75 (caffeine). Twenty-seven of 33 nutrient intakes estimated by 3-day diet record were significantly lower than by FFQ (P<0.05). Three-day diet records underestimated dietary intake relative to the FFQ and 24-hour recall methods. Fifty percent of records were not completed. Energy estimates from the FFQ and 24-hour recall were similar to each other.
The 24-hour recall gave higher mean dietary intake estimates, but would require multiple contacts with this difficult-to-reach population. The FFQ that was specifically designed for this Hispanic population performed well relative to the other methods.
药物滥用是居住在美国东北部的西班牙裔人群感染人类免疫缺陷病毒（HIV）的一个重要风险因素，药物滥用和HIV感染均与营养缺乏有关。对于可能存在药物滥用情况的感染或未感染HIV的西班牙裔成年人，选择最适合的膳食评估方法仍不明确。
参与者被招募进三组之一：HIV感染的药物滥用者、未感染HIV的药物滥用者、感染HIV的非药物滥用者。完成三种膳食方法中两种的受试者被纳入横断面成对比较。
一项关于药物滥用在HIV/获得性免疫缺陷综合征相关体重减轻中作用的前瞻性队列研究的基线数据。
286名登记参与者完成了282份食物频率问卷（FFQ）、142份3天饮食记录和270份24小时膳食回顾。FFQ与3天饮食记录之间经能量调整和去衰减后的相关性范围为0.11（碳水化合物）至0.75（咖啡因）。3天饮食记录估计的33种营养素摄入量中有27种显著低于FFQ（P<0.05）。相对于FFQ和24小时膳食回顾方法，3天饮食记录低估了膳食摄入量。50%的记录未完成。FFQ和24小时膳食回顾得出的能量估计值彼此相似。
24小时膳食回顾得出的平均膳食摄入量估计值更高，但需要与这个难以接触到的人群进行多次接触。专门为该西班牙裔人群设计的FFQ相对于其他方法表现良好。
