Abstract Background In China, many people are apt to participate in regular physical examination as a precaution. Some simplified food frequency questionnaire have been designed and used. However, the effectiveness of questionnaire is absent. This study was conducted to examine the reliability and validity of simplified food frequency questionnaire (SFFQ) used among physical examination adults in southwest region of China. Methods This study was a cross sectional study among physical health examination adults in Southwest region of China. A total of 239 participants aged 20-65 were conducted during February to June in 2019. The performance of the SFFQ was evaluated by the mean of three-day 24-hour dietary recalls (3R24). The relative validity and agreement was assessed by the Pearson`s correlation and intra-class correlation coefficients(ICC) respectively. Results The median energy-adjusted ICC of food groups between SFFQ2 and SFFQ1 was 0.59 (range: 0.49-0.73) and the ICC of nutrients was 0.47(range: 0.39-0.76). The Pearson correlation showed the validity between the SFFQ1 and 3R24, which ranged from -0.086 to 0.93 for food and and 0.21 to 0.71 for nutritions, respectively. Energy-adjustment slightly increased the correlation coefficients. Conclusions The reliability and validity of the SFFQ was acceptable. It could be an appropriate dietary assessment tool for future epidemiological studies in physical health examination adults among Chinese in southwest China.

AbstractObjectiveTo compare intra- and inter-method reliability of a semi-quantitative food frequency questionnaire (FFQ) designed specifically to measure beta carotene (BC) and retinol intake, using two methods – the limits of agreement (LOA) and the correlation coefficient.DesignA cross-sectional study of dietary intake.SettingA randomized trial of vitamin A supplements in 2769 subjects with past asbestos exposure.SubjectsData from 57 men and 26 women, aged 28–72 years, living in Western Australia.MethodsThe FFQ was administered at baseline (FFQ1) and repeated 1 year later (FFQ2). Four 1-week diet records (DRs) were completed during the year.ResultsMean agreement between FFQ2 and FFQ1 was 120% for BC and 98% for retinol. LOA were 47–306% and 21–459%, respectively. Mean agreement between FFQ2 and the DR was 149% for BC and 63% for retinol; LOA were 50–447% and 11–349%, respectively. Mean agreement and LOA varied across energy intakes. Between the DR and FFQ2, correlation coefficients were 0.36 for BC and 0.51 for retinol. These varied considerably across age, gender and energy intakes and were not in accordance with limits of agreement findings.ConclusionAlthough correlation coefficients were positive and significant, there was less than ideal intra-method and inter-method reliability shown by the limits of agreement method. Bias was uneven across the range of intakes, the LOA were wide and, compared with the DR, the FFQ significantly over-estimated BC and under-estimated retinol. This shows the limitations of calculating correlation coefficients alone, for assessing reliability and validity.

The purpose of this study was to evaluate the association between non-nutritive sweetener (NNS) consumption and stress and anxiety, among a sample of college students. Two-hundred and twenty-seven students from a large mid-western university participated in this cross-sectional study. Students completed an online survey that evaluated NNS using a validated food frequency questionnaire. Stress and anxiety were evaluated using previously validated instruments. Most students reported very low/low/average concern for stress (63.9%), and had low/moderate anxiety (82.3%). Participants experiencing high and very high levels of stress had significantly higher NNS consumption compared to those with a very low and low risk, and concern for stress ( p < .046; d = 0.28). There was no difference however for NNS intake and anxiety. Reduction of artificial sweetener intake may be associated with stress levels among college students. However, more research is needed to examine any causal relationship between artificial sweetener intake and stress.

Background and Objectives: The techniques directed to the cranial field in osteopathy are the most questioned due to the lack of scientific evidence. In osteopathic practice, manual palpation is essential and, therefore, measuring reliability is fundamental. The objective of study is to assess the reliability and validity of osteopathic treatment depending on experience. Materials and Methods: A cross-sectional study of reliability and validity was conducted. For measurements, a strain gauge was placed on the sphenobasilar synchondrosis of the skull base, and three maneuvers (lateral compression, anteroposterior compression and compression maneuver of the mastoids) were repeated 25 times each by osteopaths with different time of experience (5-10 years, 1-5 years, &lt;1 year). Measurement averages were computed for each of the three maneuvers to verify the average effect of each group in comparison to that of the Gold Standard (GS) (&gt;10 years of experience). Data were analyzed to check for inter- and intra-observer reliability using intra-class correlation coefficients (ICC). Results: Reliability and validity in 5-10 experience of observer 1 and observer 2 in the tree maneuvers was excellent (p&lt;0.001) against GS. Poor or enough reproducibility and concordance were observed in osteopaths with less experience. Conclusion: Experience of osteopaths determines the efficacy of cranial maneuvers in osteopathic treatment for patients&rsquo; rehabilitation.

In this study, we constructed a new sense of coherence scale (SOC II), where we eliminated the notion of predictability (that life is meant to be predictable), which was present in the original SOC scale developed by Aaron Antonovsky (1923–1994) (SOC-29 and SOC-13). Our hypothesis was that SOC II would show a higher degree of association with physical health than the original SOC scale. In order to test this idea, we used a cross-sectional study including 4,648 Danes and used the three different health measures: self-evaluated physical health, physical symptoms, and self-evaluated psychological health. We found that SOC II was positively associated with all three health measures with the correlation coefficients 0.338, 0.282, and 0.578, respectively. Furthermore, we found dose response tendencies for all three health measures across groups of SOC, since health improved with a higher SOC. By means of regression analysis, we found that SOC was significantly associated with all three health measures after stratifying for demographic variables, life style variables, life form variables, and attitude variables, respectively. We conclude from this study that the SOC II scale we developed seems better associated with physical health than found with the original SOC scale. We also postulate that the concept of predictability was irrelevant, or even disturbing, and should not be included in the SOC scale.
