  • Independent associations of dairy and calcium intakes with colorectal cancers in the Adventist Health Study-2 cohort

    Open AccessYessenia Tantamango-Bartley, Synnove F Knutsen et al.ARTICLEPublic Health Nutrition2017

    Objective Results associating dairy and Ca intakes with colorectal cancer (CRC) risk have been mixed. Most previous analyses have suffered from confounding between dairy and Ca intakes. We examined independent associations between these variables, also dairy foods, and CRC incidence in a population with a large range of dairy intakes. Design Adventist Health Study-2 is a cohort study where subjects were enrolled 2002–2007. Proportional hazard reg…

  • The association between soya consumption and serum thyroid-stimulating hormone concentrations in the Adventist Health Study-2

    Open AccessSerena Tonstad, Karen Jaceldo-Siegl et al.ARTICLEPublic Health Nutrition2016

    Objective Consumers may choose soya foods as healthful alternatives to animal products, but concern has arisen that eating large amounts of soya may adversely affect thyroid function. The present study aimed to examine the association between soya food consumption and serum thyroid-stimulating hormone (TSH) concentrations in North American churchgoers belonging to the Seventh-day Adventist denomination that encourages vegetarianism. Design Partic…

  • Effect of dried California Mission figs on mineral status and food replacement

    Open AccessHeba K Alshaeri, Zuhair S Natto et al.ARTICLEPublic Health Nutrition2015

    Objective Figs are a rich source of several different minerals and fibres. We studied the effect of the consumption of dried California Mission figs on mineral and nutrient levels, as well as the effect of the addition of figs to a self-selected habitual diet on dietary patterns. Design A crossover randomized controlled trial study design in which participants with a mean of age of approximately 56 years were randomly assigned to eat either their…

  • Vegetarian diets and blood pressure among white subjects: Results from the Adventist Health Study-2 (AHS-2)

    Open AccessBetty Johanne Pettersen, Ramtin Anousheh et al.ARTICLEPublic Health Nutrition2012

    Objective Previous work studying vegetarians has often found that they have lower blood pressure (BP). Reasons may include their lower BMI and higher intake levels of fruit and vegetables. Here we seek to extend this evidence in a geographically diverse population containing vegans, lacto-ovo vegetarians and omnivores. Design Data are analysed from a calibration sub-study of the Adventist Health Study-2 (AHS-2) cohort who attended clinics and pro…

  • Validation of self-reported anthropometrics in the Adventist Health Study 2

    Open AccessMaira Bes-Rastrollo, Joan Sabate et al.ARTICLEBMC Public Health2011

    Self-reported anthropometric data showed high validity in a representative subsample of the AHS-2 being valid enough to be used in epidemiological studies, although it can lead to some underestimation of obesity

  • Race-specific validation of food intake obtained from a comprehensive FFQ: The Adventist Health Study-2

    Open AccessKaren Jaceldo-Siegl, Karen Jaceldo‐Siegl et al.ARTICLEPublic Health Nutrition2011

    Objective To assess race-specific validity of food and food group intakes measured using an FFQ. Design Calibration study participants were randomly selected from the Adventist Health Study-2 (AHS-2) cohort by church, and then by subject-within-church. Intakes of forty-seven foods and food groups were assessed using an FFQ and then compared with intake estimates measured using six 24 h dietary recalls (24HDR). We used two approaches to assess the…

  • Validation of nutrient intake using an FFQ and repeated 24 h recalls in black and white subjects of the Adventist Health Study-2 (AHS-2)

    Open AccessKaren Jaceldo-Siegl, Karen Jaceldo‐Siegl et al.ARTICLEPublic Health Nutrition2010

    Objective To validate a 204-item quantitative FFQ for measurement of nutrient intake in the Adventist Health Study-2 (AHS-2). Design Calibration study participants were randomly selected from the AHS-2 cohort by church, and then subject-within-church. Each participant provided two sets of three weighted 24 h dietary recalls and a 204-item FFQ. Race-specific correlation coefficients ( r ), corrected for attenuation from within-person variation in …

  • Validation of a food-frequency questionnaire for measurement of nutrient intake in a dietary intervention study

    Open AccessGina Segovia-Siapco, Gina Segovia‐Siapco et al.ARTICLEPublic Health Nutrition2007

    Objective To validate a 171-item semi-quantitative food-frequency questionnaire (FFQ) for measurement of nutrient intake in an intervention trial based on walnut supplementation. Design and setting Free-living adults from Southern California were randomly assigned to either an intervention (walnut-supplemented) or a control diet. The prescribed 6-month intervention was ≥ 28 g of walnuts per day for the walnut-supplemented group and ≤ 2 g of walnu…

  • Caregiving between Two Cultures: An Integrative Experience

    Open AccessPatricia S Jones, Xinwei Esther Zhang et al.ARTICLEJournal of Transcultural Nursing2002

    In 1995, more than half of elderly immigrants to the United States were born in Asia or the Pacific region. The purpose of this study was to describe the process of caring for elderly parents by Asian American women. Forty-one women (22 Chinese American and 19 Filipino American) caring for elderly parents were interviewed in a study based on Strauss and Corbin’s grounded theory methodology (1990). Although the women were moderately acculturated, …
