Blood donors are on average healthier than the general population, a phenomenon known as the "healthy donor effect." Earlier studies have also pointed to healthier behaviors among whole blood donors than the general population. This study is aimed at assessing the prevalence of four healthy behaviors (sufficient physical activity, avoiding cigarette smoking, low to moderate alcohol use, and maintaining a healthy weight) among platelet donors and to compare the results with those in the general population of similar ages.
Eighty-six platelet donors were asked to complete a questionnaire designed to assess physical activity, smoking, and alcohol use. Sociodemographic information including gender, age, and education was also collected from all participants. Chi-square statistics and logistic regression were used in statistical analysis.
The mean age of the study donors was 51 years, 56% were female. Most were employed (90%), and 48% hold a bachelor's or higher degree. The prevalence of healthy behaviors differed by education gradients but not by gender and age. About 49% of the donors met the weekly physical activity recommendations, less than 5% were daily smokers, and~26% were classified as more frequent drinkers (≥1 to ≤5 times per week). The corresponding percentages for the general population were, respectively, 33%, 13%, and 35%. The prevalence of overweight and obesity, as assessed by body mass index (BMI), among donors were 50% and 29%, respectively, much higher than the current prevalence of overweight and obesity of 37% and 19%, respectively, among adults in the general population.
The individual health behaviors of the majority of the study population could be characterized by a relatively high level of physical activity, low prevalence of daily smoking, and moderate alcohol drinking. The above-average overweight/obesity prevalence among platelet donors in this cohort is of concern because of the potential serious health consequences and it warrants further reflection.
与一般人群相比，献血者的平均健康状况更好，这种现象被称为“健康献血者效应”。早期的研究还指出，与一般人群相比，全血献血者的健康行为更为普遍。本研究旨在评估血小板献血者中四种健康行为（充足的体力活动、避免吸烟、低至中度饮酒和保持健康体重）的流行率，并将结果与同年龄段的一般人群进行比较。
86 名血小板献血者被要求完成一份问卷，旨在评估体力活动、吸烟和饮酒情况。所有参与者还收集了社会人口统计学信息，包括性别、年龄和教育程度。统计分析采用卡方检验和逻辑回归。
研究献血者的平均年龄为 51 岁，56%为女性。大多数人有工作（90%），48%拥有学士或更高学位。健康行为的流行率因教育程度而异，但与性别和年龄无关。约 49%的献血者符合每周体力活动建议，不到 5%的人是每天吸烟者，约 26%的人被归类为更频繁的饮酒者（每周 1 至 5 次）。相应的百分比在一般人群中分别为 33%、13%和 35%。根据体重指数（BMI）评估，献血者超重和肥胖的比例分别为 50%和 29%，明显高于一般人群中成年人目前超重和肥胖的比例分别为 37%和 19%。
该研究人群的大多数个体健康行为可以用较高水平的体力活动、低水平的每日吸烟率和中度饮酒来描述。在这一献血者队列中，超重/肥胖的比例高于平均水平，这令人担忧，因为这可能会带来严重的健康后果，需要进一步反思。
