Regular screenings are important for reducing cancer morbidity and mortality. There are several barriers to receiving timely cancer screening, including overweight/obesity. No study has examined the relationship between overweight/obesity and cancer screening among American Indian/Alaska Natives (AI/ANs).
To describe the prevalence of fecal occult blood testing (FOBT) and prostate-specific antigen (PSA) testing among AI/AN men within the past year by age and rurality, and determine if body mass index (BMI) is associated with screening.
A national cross-sectional survey was administered face-to-face to 2,447 AI/AN men at least 55 years of age in 2004-2005. Participants were asked when they last had FOBT and PSA testing. BMI was derived from self-reported height and weight, and rurality of residence was defined by rural-urban commuting area codes. We assessed the association of cancer screening and BMI with logistic regression models, adjusting for demographic and health factors.
Prevalence of up-to-date FOBT and PSA testing were 23% and 40%, respectively. Older men were more likely than younger men to have FOBT and PSA testing. BMI was not associated with receipt of FOBT or PSA testing.
This is the first study to examine obesity and health care in AI/ANs. As in other populations, FOBT and PSA testing were suboptimal. Screening was not associated with BMI. Studies of AI/AN men are needed to understand the barriers to receiving timely screenings for prostate and colorectal cancer.
定期筛查对于降低癌症发病率和死亡率至关重要。接受及时癌症筛查存在若干障碍，包括超重/肥胖。尚无研究调查美国印第安人/阿拉斯加原住民（AI/ANs）中超重/肥胖与癌症筛查之间的关系。
按年龄和居住地区描述过去一年中AI/AN男性粪便潜血试验（FOBT）和前列腺特异性抗原（PSA）检测的患病率，并确定体重指数（BMI）是否与筛查相关。
2004 - 2005年对2447名至少55岁的AI/AN男性进行了全国性横断面面对面调查。询问参与者上次进行FOBT和PSA检测的时间。BMI根据自我报告的身高和体重得出，居住地区根据城乡通勤区号定义。我们使用逻辑回归模型评估癌症筛查与BMI之间的关联，并对人口统计学和健康因素进行了调整。
最新的FOBT和PSA检测患病率分别为23%和40%。老年男性比年轻男性更有可能进行FOBT和PSA检测。BMI与接受FOBT或PSA检测无关。
这是第一项研究AI/ANs中肥胖与医疗保健情况的研究。与其他人群一样，FOBT和PSA检测情况并不理想。筛查与BMI无关。需要对AI/AN男性进行研究，以了解接受前列腺癌和结直肠癌及时筛查的障碍。
