Health behaviors and their determinants in multiethnic, active Israeli seniors

To assess factors that affect the adoption of healthy lifestyles among a variety of active Israeli seniors, a survey was conducted in 2002 at the Peiluyada, a physical activity-oriented health fair for seniors held annually in Israel from 1995 to 2002. A multi-language, self-administered questionnaire, assessing predisposing factors, barriers and health-protective behaviors, was fielded to potential participants. Response rate at the event was 51%. Hebrew and Arabic speakers generally characterized their health as good to very good, while Russian speakers' health was rated only poor to fair. Over 80% engaged in regular physical activity, were satisfied with their diet, and conformed to international nutritional recommendations. Vaccination coverage against influenza (81%) and pneumocccocus (58%) was highest among Arabic speakers, and lowest among Russian speakers (33.5% and 12%, respectively). Higher age (> or =75 years) was significantly associated with receiving a vaccination against influenza. Major barriers to exercise included low motivation and poor physical health or disability. Health-related dietary restrictions were the leading nutritional barrier. Prominent barriers to vaccination included concerns about vaccine effectiveness (39%) and side effects (29%). Leading cues to action were a recommendation from one's doctor (67%) and from a healthcare worker (51%).     

强化降脂治疗对老年不稳定性心绞痛病人的临床效果

目的 :评价强化降脂治疗对老年不稳定性心绞痛 (UAP)病人预后的影响 ,探讨降脂药物的作用机制。方法 :确诊为老年UAP病人 79例 ,随机分为常规药物治疗组 (常规组 ,n =3 9)和常规药物加立普妥 (lipitor)组 (立普妥组 ,n =40 ) ,立普妥初始剂量 10mg/d ,根据低密度脂蛋白胆固醇达标情况 ( <2 6mmol/L)增量 ,最大剂量 40mg/d。以 12导联ST段压低数值总和 (∑ST)和 1周内心绞痛发作次数作为心肌缺血指标 ,空腹取静脉血测定血糖、甘油三酯、低密度脂蛋白胆固醇、血浆一氧化氮、纤溶酶原激活物抑制物、C 反应蛋白、心肌酶谱、肝肾功能及血、尿常规。 6个月后复测上述指标 ,同时观察半年内心脑血管事件。两组病人年龄、性别、血压、心率、吸烟、空腹血糖及危险分层比例无明显差异。结果 :6个月后共纳入病人 76例 (常规组 ,n =3 8;立普妥组 ,n =3 8)。用药前后比较 :两组病人用药后心绞痛发作次数及∑ST均较用药前明显下降 ,立普妥组下降更明显 ,均有显著性差异 (P <0 0 5及P <0 0 1) ;立普妥组治疗后较治疗前甘油三酯及低密度脂蛋白胆固醇明显下降 ,有显著性差异 (P <0 0 5及P <0 0 1) ,一氧化氮明显增加 ,有极显著性差异 (P <0 0 1) ;C 反应蛋白及纤溶酶原激活物抑制物明显降低 ,有显著性差异 (P <0 0
