The arguments presented by Iacono and Verschuere et al. against the publication of the Mangan et al. field study of the Quadri-Track Zone Comparison Technique in Physiology & Behavior , are based largely on dated articles that examined control question polygraph techniques whose psychological test structures, physiological analyses, and scoring systems are significantly different than those of the Quadri-Track ZCT. Iacono and Verschuere et al. alleged that the Quadri-Track ZCT is biased against the innocent and can be defeated with the use of countermeasures without considering the technique's unique "remedial inside track" that quantifies the innocent examinee's fear of error-and the guilty examinee's hope of error-which are factored into the overall score, thus avoiding false positive and false negative errors. Their objection to the use of confessions as the criterion for ground truth presumes that the polygraph examinations conducted in this field study were conducted in a vacuum. They ignored the various methods of post-test confirmation and research studies that support the use of confessions as ground truth. Verschuere et al. cited the National Research Council's 2003 report to support their conviction that the accuracy of polygraph tests is well below perfection and errors often occur. However, they failed to mention that the accuracy range values of the seven field studies which met the National Research Council's scientific criteria were from 0.711 to 0.999 with a median value of 0.89, and that the field study with the highest accuracy (0.999) was from a published 1989 field study on the Quadri-Track Zone Comparison Technique.  相似文献

Background: Reaching the American Cancer Society challenge goal for the nation to reduce cancer incidence by 25% by 2015 will be influenced in part by the epidemic of obesity. The purpose of this study was to estimate the impact of obesity on the number obesity-attributable incident cancers in the U.S. in 2007 and on trends on cancer incidence rates. Methods: Using estimated relative risks (RRs) for obesity vs. normal weight/height from published meta-analyses and/or large cohort studies, and the prevalence of obese adults from the latest national surveys, attributable risk percent (ARP) and numbers of obesity-attributed incident cancers in 2007 were estimated. Using the ARPs, the impact of obesity trends on trends in incidence rates for certain obesity-related cancers was estimated for the calendar years (1976-1980 through 2001-2004) for which cancer rates and obesity prevalence rates were available. Results: An estimated 33,966 new cancers (4% of all estimated cancers) in males and 50,535 (7% of all estimated cancers) in females diagnosed in 2007, or 6% of all cancers, may be potentially attributable to obesity. Without the impact of rising obesity rates, incidence rates might have declined (instead of remaining stable) from 1988-1994 to 2001-2004 for uterus, breast and certain other cancers. Conclusions: Obesity may contribute to about 6% of U.S. incident cancers, apparently has affected recent trends in incidence rates for certain cancers, and is important because of increasing prevalence in the U.S. population.  相似文献

BackgroundEpidemiologic evidence of the effect of dietary selenium intake on stroke risk remains controversial. This study aimed to examine the cross-sectional correlation between dietary selenium intake and the risk of stroke in adults.Materials and methodsWe retrospectively analysed 39,438 participants from the National Health and Nutrition Examination Survey 2003–2018, aged 20–85 years. Participants were divided into quartiles depending on daily dietary selenium intake: quartile 1 (0–77 μg), quartile 2 (77–108 μg), quartile 3 (108–148 μg), and quartile 4 (148–400 μg). The dose-response relationship was assessed using the restricted cubic spline function.ResultsThe adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of stroke were 0.70 (0.55, 0.88) for participants in quartile 2, 0.71 (0.53, 0.93) for quartile 3, and 0.61 (0.43, 0.85) for quartile 4 compared with that in quartile 1. p-Value for trend through quartiles was .007. A non-linear negative correlation between dietary selenium intake and stroke was observed in the threshold effect analysis and restricted cubic spline function (p-value for non-linearity < .001). An initial decrease in odds of stroke lower than 105 μg/day selenium intake (0.61 [0.44, 0.85], p = .004) was followed by a platform beyond 105 μg/day (0.97 [0.81, 1.16], p = .723). In the subgroup analysis, adjusted ORs (95% CIs) of stroke were 0.51 (0.36, 0.70) for female participants, 0.63 (0.40, 0.99) for participants with age <60 years, 0.63 (0.47, 0.85) for participants with poverty-income ratio < 2.14, 0.66 (0.50, 0.87) for participants with overweight and obesity, 0.66 (0.52, 0.84) for participants with hypertension, 0.72 (0.53, 0.97) for participants without diabetes, and 0.72 (0.56, 0.92) for non-anaemic participants.ConclusionsDietary selenium had a negative and non-linear correlation with the risk of stroke in adults. The correlation varied across different population subgroups.

KEY MESSAGES

  • Dietary selenium had a negative and non-linear correlation with the risk of stroke in adults.
  • Non-linear negative correlation trends were observed in subpopulations of females, age <60 years, poverty-income ratio <2.14, overweight and obesity, hypertension, non-diabetes, and non-anaemia.
  • Dietary selenium intake of approximately 105 μg per day has an optimum effect on stroke.

Indices of overall dietary patterns are used in epidemiologic research to examine the relationship between nutrition and health. The objective of this study was to develop and validate an interpretable summary measure of dietary intake of whole plant foods (WPF; whole grains, vegetables, whole fruit, legumes, nuts, seeds) because of their similar nutritional characteristics and health effects. Six candidate WPF measures were calculated using data from subjects (age ≥6 years) participating in the 1999-2000 and 2001-2002 National Health and Nutrition Examination Survey. Measures differed by the inclusion or exclusion of potatoes and whether they were expressed as total intake or as a proportion of energy (4180 kJ) or mass (kg) consumed. Both standard and nontruncated (allowed to vary proportionally with intake) Healthy Eating Index-2005 (HEI-2005) scores were calculated. Regression analysis examined the associations between WPF and HEI-2005 measures, and between all diet measures and serum carotenoid concentration, serum lipids, fasting glucose, insulin, C-peptide, and C-reactive protein. Mean total WPF intake was 3.6 cup/oz equivalents, or 1.7 cup/oz equivalents per 4180 kJ and per kg. The largest R2 between WPF and HEI-2005 measures was found for energy-adjusted WPF including potatoes and nontruncated HEI-2005 (R2 = 0.50). All diet measures were positively related to serum carotenoids (P <.001) and were similarly related to health indicators (R2 range from 0.003 to 0.16, P <.045 for regressions, indicating significant associations between WPF measures and health indicators). Whole plant food measures are interpretable indicators of dietary intake that are significantly related to nutrition and health biomarkers and may be of public health use.  相似文献
