The aims of this study were to determine the factors that influence blood donation in different demographic groups in a multi-ethnic, multicultural community, and to devise a strategy for a national campaign to increase voluntary non-remunerated blood donations. The majority (87%) of blood donations in Trinidad and Tobago are replacement donations. Seventy per cent of the country's transfusion needs are not met. In 1998, the World Health Assembly recommended that reliance on replacement donations should be phased out due to their association with an increased risk of transfusion-transmitted infections. An observer-administered questionnaire was completed by 1423 respondents in a multi-ethnic borough in central Trinidad. Respondents were classified as donors or non-donors and grouped by age, race, religion, employment status and highest level of education. The prevalence of a history of blood donation and the factors that encouraged donation or conversely discouraged donation in each demographic group were recorded. A total of 1146 (81.2%) respondents had never donated blood. Of the 277 (18.8%) who had previously donated, replacement for a family member or friend was the most common reason (86.9%). The prevalence of donation was low in all racial, religious, gender, educational and age groups. However, there were significant demographic variations. The majority (71.3%) of non-donors cited a lack of information as a major reason for non-donation and expressed a willingness to donate if access to information and donation facilities were improved. Voluntary blood donation in Trinidad and Tobago could be greatly increased by a national education campaign and increased accessibility to donation centres. This would ensure a safer and more reliable blood supply.
本研究的目的是确定在一个多民族、多元文化社区中不同人口群体献血的影响因素，并制定一项全国性运动的策略，以增加自愿无偿献血。特立尼达和多巴哥的大多数（87%）献血是替代献血。该国70%的输血需求未得到满足。1998年，世界卫生大会建议逐步淘汰对替代献血的依赖，因为其与输血传播感染风险增加有关。在特立尼达中部一个多民族行政区，1423名受访者完成了一份由观察员管理的问卷。受访者被分为献血者或非献血者，并按年龄、种族、宗教、就业状况和最高教育水平进行分组。记录了每个人口群体的献血史患病率以及鼓励献血或相反阻碍献血的因素。共有1146名（81.2%）受访者从未献血。在之前献血的277名（18.8%）受访者中，为家人或朋友替代献血是最常见的原因（86.9%）。所有种族、宗教、性别、教育和年龄组的献血率都很低。然而，存在显著的人口统计学差异。大多数（71.3%）非献血者表示缺乏信息是不献血的主要原因，并表示如果信息获取和献血设施得到改善，愿意献血。通过全国性的教育运动和增加献血中心的可及性，可以大大增加特立尼达和多巴哥的自愿献血。这将确保更安全、更可靠的血液供应。
