【摘要】
研究目的：评估巴西圣保罗州容迪亚伊市维拉安娜（Vila Ana）与莫拉达达斯维尼亚斯（Morada das Vinhas）地区青少年对主要性传播疾病（sexually transmitted diseases, STDs）及宫颈癌的预防与认知情况，同时考察健康教育讲座的即时干预效果。
研究方法：本研究采用前瞻性横断面研究设计，通过在健康教育讲座前后发放调查问卷的方式，对特定女性青少年群体的性传播疾病及宫颈癌相关认知水平进行评估。
研究结果：讲座结束后，受试者在性教育知识、人乳头瘤病毒（Human Papillomavirus, HPV）认知（提升幅度达44%）以及宫颈癌预防知识（提升幅度达22%）方面的正确作答比例均有所上升。
研究结论：本研究纳入的青少年群体对性传播疾病及宫颈癌的认知水平普遍偏低，但低成本的健康教育讲座即可有效改善这一现状，且对公共卫生服务体系的投入需求极低。
