“…A report of the PLCO (Prostate, Lung, Colorectal, and Ovarian) Cancer Screening Trial found that a small proportion of invitees enrolled, and that enrollment was higher among those who were female, white, older, and living in higher-income census blocks (Lamerato, Marcus, Jacobsen, & Johnson, 2008). These data are consistent with other reports about enrollment in cancer screening trials (Steffen et al, 2008). …”

“…For example, having an experienced trial coordinator, visiting participants at home, high publicity, high perceived clinical benefit by clinicians, and practice incentives contributed to recruitment success in one study (McKinstry et al 2007). It seems that use of multiple strategies, culturally sensitive approaches, incentives, repeated invitations, and low burden on participant can enhance study enrollment (Grunfeld, Zitzelsberger, Coristine, & Aspelund, 2002; Rubin et al, 2002; Steffen et al, 2008). …”

Many cancer screening studies are conducted in primary care settings yet few systematically analyze recruitment challenges found at these sites. During a randomized trial promoting colorectal cancer screening, we implemented a process evaluation of recruitment. Recruiters maintained logs that registered the numbers of patients entering the clinic, approached by recruiters, declining to participate; and reasons for non-approach and non-participation. One-half of age-eligible patients were approached (n=1489), and half of those who met basic eligibility requirements agreed to engage further (n=527). A small proportion of patients (n=98) completed the 15-minute assessment before their appointment. Major reasons for non-approach included previous approach, patients called to the exam room, and appearing ill. The major reason for non-participation was “not interested”; a few patients did not want to share contact information. Some participants exited the assessment mid-way due to further ineligibility or time limitations. Best practice recommendations for recruitment in primary care are discussed.

“…Additionally, there was little difference for missing ER status between Hispanic (24.7%) and non-Hispanic white (23.0%) women diagnosed with invasive cancer ( P = 0.41), and overall, it is unlikely that missing ER status is associated with folate intake. The participation rate was lower in our study than for some previous studies, increasing the potential for selection bias, although obtaining high response rates in minority populations is a universal problem [77], [78]. To obtain a better understanding of the potential impact of poor response on study findings, we evaluated several factors and showed comparability for participants and non-participants [28].…”

Dietary Intake of Folate, B-Vitamins and Methionine and Breast Cancer Risk among Hispanic and Non-Hispanic White Women

BackgroundLow dietary folate intake is associated with several neoplasias, but reports are inconsistent for breast cancer. Additionally, the association of folate with breast cancer estrogen receptor (ER) status is not well established.ObjectiveTo determine if dietary intakes of folate, B-vitamins (B2, B6, B12) and methionine are associated with breast cancer risk and ER status in Hispanic, and non-Hispanic White women in the southwestern US.Materials and MethodsPrimary breast cancer cases (n = 2,325) in the 4-Corners region (Arizona, Colorado, New Mexico and Utah), diagnosed between October 1999 and May 2004, were identified through state cancer registries. Controls (n = 2,525) were frequency-matched by ethnicity and age (±5 years). Dietary intake, physical activity and other exposures were assessed using in-person interviews. Risk was assessed through multivariable and multinomial logistic regression with adjustment for relevant covariates.ResultWhile there was no overall association with breast cancer, the highest quartile of folate intake was marginally inversely associated with ER− breast cancer (Odds Ratio (OR) = 0.50, 95%CI 0.25–1.00, p for trend = 0.07). Vitamin B12 intake was inversely associated with breast cancer also (OR = 0.73, 95%CI 0.53–1.00, p for trend = 0.06), particularly for the highest quartile of ER+ breast cancer (OR = 0.67, 95%CI 0.46–0.99, p for trend = 0.06), among NHW women (OR = 0.49, 95%CI 0.29–0.81, p for trend = 0.01) and invasive breast cancer (OR = 0.63; 95%CI: 0.42, 0.93, P trend = 0.01). Methionine intake was also inversely associated with ER+ breast cancer (OR for 4th quartile = 0.83, 95%CI 0.66–1.03, p for trend = 0.04), primarily among Hispanic women (OR = 0.71, 95%CI 0.47–1.06, and P for trend = 0.02).ConclusionHigher intake of folate is marginally associated with a lower risk for ER− breast cancer, and higher intakes of vitamin B-12 and methionine are marginally associated with a lower risk of ER+ breast cancer.

“…In our own study, the TRacking Adolescents Individual Lives’ Survey (TRAILS), extra recruitment effort at the first measurement wave consisted of one or two house visits after no response to both an initial and a reminder letter had been received, and offering a two-month reflection period if the initial participation request was at an inconvenient time [5]. Different studies have shown that recruitment efforts lead to a more representative sample in terms of sex, age, race, socio-economic status and health [5,11,12]. Although the representativeness increases, the quality of the data has been shown to decrease with extra recruitment effort, because of more missing values and errors in data from late compared to early responders [10,12].…”

BackgroundExtensive recruitment effort at baseline increases representativeness of study populations by decreasing non-response and associated bias. First, it is not known to what extent increased attrition occurs during subsequent measurement waves among subjects who were hard-to-recruit at baseline and what characteristics the hard-to-recruit dropouts have compared to the hard-to-recruit retainers. Second, it is unknown whether characteristics of hard-to-recruit responders in a prospective population based cohort study are similar across age group and survey method.MethodsFirst, we compared first wave (T1) easy-to-recruit with hard-to-recruit responders of the TRacking Adolescents’ Individual Lives Survey (TRAILS), a prospective population based cohort study of Dutch (pre)adolescents (at first wave: n = 2230, mean age = 11.09 (SD 0.56), 50.8% girls), with regard to response rates at subsequent measurement waves. Second, easy-to-recruit and hard-to-recruit participants at the fourth TRAILS measurement wave (n = 1881, mean age = 19.1 (SD 0.60), 52.3% girls) were compared with fourth wave non-responders and earlier stage drop-outs on family composition, socioeconomic position (SEP), intelligence (IQ), education, sociometric status, substance use, and psychopathology.ResultsFirst, over 60% of the hard-to-recruit responders at the first wave were retained in the sample eight years later at the fourth measurement wave. Hard-to-recruit dropouts did not differ from hard-to-recruit retainers. Second, extensive recruitment efforts for the web based survey convinced a population of nineteen year olds with similar characteristics as the hard-to-recruit eleven year olds that were persuaded to participate in a school-based survey. Some characteristics associated with being hard-to-recruit (as compared to being easy-to-recruit) were more pronounced among non-responders, resembling the baseline situation (De Winter et al.2005).ConclusionsFirst, extensive recruitment effort at the first assessment wave of a prospective population based cohort study has long lasting positive effects. Second, characteristics of hard-to-recruit responders are largely consistent across age groups and survey methods.
