Evaluation of the nutrition literacy assessment questionnaire for college students and identification of the influencing factors of their nutrition literacy

BACKGROUND

Nutrition health has become a major public health issue in both high and middle-income countries. Nutrition literacy is an important indicator to evaluate the effect of public health intervention and one of the important concepts in health promotion. Thus, this study aimed to verify the reliability and validity of a nutrition literacy assessment questionnaire (NLAQ) and investigate the associated factors of nutrition literacy among college students.

METHODS

We conducted a cross-sectional online survey of college students from April to November 2022 in Wuhan (N = 774). We employed the Cronbach's alpha coefficient, exploratory and confirmatory factor analysis to evaluate the reliability and validity. We used latent profile analysis to classify the nutrition literacy. We conducted Chi-square test and binary logistic regression to identify the influencing factors.

RESULTS

The Cronbach's alpha coefficient of the NLAQ and its dimension was ranging from 0.837 to 0.909. The common factors were consistent with the original dimensions. All indicators met the requirements (χ2/df = 6.16 < 8, GFI = 0.929, NFI = 0.939, CFI = 0.948, RMSEA = 0.082 < 0.1). College students' disciplines (χ2 = 7.769, P = 0.021), mothers' education level (χ2 = 26.599, P < 0.001), and fathers' occupation type (χ2 = 11.218, P = 0.024) had impacts on nutrition literacy.

CONCLUSION

The NLAQ has good reliability and validity, and could be used as a measurement tool to evaluate college students' nutrition literacy. Schools and families should take targeted measures to improve the college students' nutrition literacy.

Development and validation of a short-version checklist for patients undergoing hemodialysis based on the International Classification of Functioning, Disability and Health

BACKGROUND

In 2009, we developed a "100-category checklist" for patients undergoing hemodialysis (HD) based on the International Classification of Functioning, Disability and Health, and we confirmed its validity. However, we found that for patients' daily assessment, 100 categories were too many. The purpose of the present study was to develop and validate a short version of the "100-category checklist."

METHODS

A total of 100 outpatients undergoing HD were recruited. They were interviewed using the "100-category checklist" and asked whether they had experienced problems after starting HD. From the "100-category checklist," we extracted categories that had greater than a 50 % rate of "yes" responses. Content validity was evaluated using the frequency of patients who had a problem in each category. Criterion validity was evaluated based on the correlation of the score from the "short-version checklist" categories with that from the Kidney Disease Quality of Life (KDQOL™) questionnaire. Construct validity was evaluated using Spearman correlation coefficients between the number of problem categories and the presence of HD-related complications. Cronbach's coefficient alpha was calculated to evaluate internal consistency.

RESULTS

Twenty-two categories were identified as problem categories. Criterion validity showed that 12 categories were significantly correlated with subscales of the KDQOL™. Construct validity showed that the presence of complications contributed to an increased number of problems associated with HD. Cronbach's coefficient alpha of this checklist was 0.79.

CONCLUSION

The "short-version checklist" had a certain degree of validity, suggesting its usefulness in a simplified assessment of patients undergoing HD.

Validity of a checklist for hemodialysis patients based on the International Classification Of Functioning, Disability and Health

In 2009, we reported a "100-category checklist" for hemodialysis (HD) patients based on the International Classification of Functioning, Disability and Health. The purpose of the present study is to evaluate the validity and reliability of this checklist. The present study included 100 participants who had been on HD for at least 5 years when they were interviewed using the checklist. Subjects were asked whether they had experienced problems in each category since starting HD treatment. Categories for which more than 25% of subjects answered "yes" were extracted as problem categories. Additionally, the Kidney Disease Quality of Life (KDQOL) instrument was administered to the study subjects. Content validity was evaluated using the frequency and percentage of subjects who had a problem in each category. Criterion validity was performed based on correlation of the findings from the "100-category checklist" categories with the findings of the KDQOL. Construct validity was assessed based on the number of problem categories extracted as external criteria in carpal tunnel syndrome (CTS), anemia, and secondary hyperparathyroidism (SHPT). For reliability evaluation, we used Cronbach's coefficient alpha. Content validity showed that 54 were identified as problem categories. Criterion validity showed that 45 categories in all components correlated significantly with each subscale of the KDQOL. Construct validity showed that CTS, anemia, and SHPT contributed to an increased number of problems associated with HD. Cronbach's coefficient alpha of the "100-category checklist" was 0.86. This study confirmed the validity and reliability of the "100-category checklist".
