Diet is among the most modifiable risk factors for chronic kidney disease (CKD) progression. Studies of beneficial dietary patterns for persons with CKD have largely utilized dietary assessment measures developed in individuals without CKD. In BMC Nephrology, Affret et al. report on their study of the reproducibility of a newly developed short 49-item food frequency questionnaire (SFFQ) adapted...
BACKGROUND Longitudinal epidemiological studies require both the periodic update of intake information via repeated dietary survey and the minimization of subject burden in responding to questionnaires. We developed a 66-item Food Frequency Questionnaire (short-FFQ) for the Japan Public Health Center-based prospective Study for the Next Generation (JPHC-NEXT) follow-up survey using major foods ...
OBJECTIVE To examine associations between self-reported discrimination and dietary intakes among South Asian (SA) people. METHODS Data from the Mediators of Atherosclerosis in South Asians Living in America study were used to analyze the relationship between self-reported discrimination and dietary behaviors (n = 866). Self-reported discrimination was measured with the 9-item continuous Every...
It is not currently known how dietary assessment in older persons is affected by cognition. In a 1997-2000 study, the authors assessed the validity and reproducibility of a modified Harvard self-administered food frequency questionnaire (SFFQ) among 118 Black and 114 White randomly selected participants, aged 68-99 years, of the Chicago Health and Aging Project. Participants completed multiple ...
Alaska Native populations are experiencing a nutrition transition and a resulting decrease in diet quality. The present study aimed to develop a quantitative food frequency questionnaire to assess the diet of the Yup'ik people of Western Alaska. A cross-sectional survey was conducted using 24-hour recalls and the information collected served as a basis for developing a quantitative food frequen...
BACKGROUND Online dietary assessment tools offer advantages over printed questionnaires, such as the automatic and direct data storage of answers, and have the potential to become valuable research methods. We developed an online survey system (web-FFQ) for the existing printed FFQ used in the JPHC-NEXT protocol, the platform of a large-scale genetic cohort study. Here, we examined the validity...
It would be of enormous public health importance if diet and physical activity, both modifiable behavioral factors, were causally related to cancer. Nevertheless, the nutritional epidemiology of cancer remains problematic, in part because of persistent concerns that standard questionnaires measure diet and physical activity with too much error. We present a new strategy for addressing this meas...
