Parental smoking in the first two years of a child's life and its associations with breastfeeding.

BACKGROUND: Exclusive breastfeeding for the first 6 months followed by ongoing breastfeeding to 12 months and beyond is associated with multiple benefits for both mother and child. Maternal smoking is associated with a reduction in breastfeeding. Little is known about the effect of partner smoking on breastfeeding. AIMS: This study explores the smoking behaviour of mothers and their partners in the first two years of a child's life and its associations with breastfeeding practice. MATERIALS AND METHODS: We performed a secondary data analysis using survey data on 1155 mothers from their third trimester of pregnancy and at six, 12 and 24 months after delivery. Survey questions included smoking status of both mother and partner and breastfeeding intention and practice. Logistic regression models were conducted at each time point. FINDINGS: Where the mother or both parents smoke, babies were less likely to be breastfed at six months of age (adjusted odds ratio (aOR) 0.29, 95% CI: 0.13-0.66) compared with families where neither parent smoked. Non-smoking mothers with smoking partners were less likely to intend to breastfeed (aOR 0.29, 95% CI: 0.11-0.82) and their babies were less likely to be breastfed at six and 12 months of age (aOR 0.64, 95% CI: 0.42-0.98 and 0.64, 95% CI: 0.43-0.95 respectively). There was no difference in breastfeeding behaviour between smoking and non-smoking parents at 24 months. CONCLUSION: Smoking parents are less likely to breastfeed their babies at ages six and 12 months. Breastfeeding promotion should target both smoking mothers and smoking partners.

Copper-Catalyzed Synthesis of 4-CF3-1,2,3-Triazoles: An Efficient and Facile Approach via Click Reaction.

Incorporation of a trifluoromethyl group with 1,2,3-triazoles motifs was described. We explored a click reaction approach for regioselective synthesis of 1-susbstituted-4-trifluoromethyl-1,2,3-triazoles in which 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) reacts with commercial 2-bromo-3,3,3-trifluoropropene (BTP) to form 3,3,3-trifloropropyne (TFP) in situ. Arising from merits associated with the availability and stability of BTP, and the high efficiencies of CuI/1,10-Phenanthroline (Phen)-catalyzed cycloaddition reactions of azides with alkynes, this readily performed click process takes place to form the target 1,2,3-triazoles in high yields, and with a wide azide substrate scope. The potential value of this protocol was demonstrated by its application to a gram-scale reaction.

Mothers' sociodemographic factors and use of health professionals for child feeding advice.

This study examined sociodemographic factors associated with mothers seeking child feeding advice from health professionals (HPs). Cross-sectional analysis of survey data from linked randomized controlled trials was conducted. Surveys asked which sources of feeding information mothers used when their child was 6 months and 5 years old. Logistic regression was used to examine associations between sociodemographic characteristics and use of information from HPs. Here, 947 and 405 mothers completed 6-month and 5-year surveys, respectively. At 6 months, multiparous mothers were less likely to seek advice from child and family health nurses (CFHNs) (adjusted odds ratio [AOR]: 0.558, 95% confidence interval [95% CI]: 0.416-0.749) and other HPs (AOR: 0.706, 95% CI: 0.542-0.919), unmarried mothers were less likely to seek advice from other HPs (AOR: 0.582, 95% CI: 0.342-0.990). At 5 years, mothers with household income ≥$80,000 p.a. were less likely to seek advice from CFHNs (AOR: 0.514, 95% CI: 0.302-0.875) and working mothers less likely to seek advice from general practitioners (GPs) (AOR: 0.581, 95% CI: 0.374-0.905). Mothers born in Australia were less likely to seek information from CFHNs (AOR: 0.462, 95% CI: 0.257-0.833) and GPs (AOR: 0.431, 95% CI: 0.274-0.677). There was a greater likelihood that multiparous mothers (AOR: 2.114, 95% CI: 1.272-3.516) and mothers of children whose fathers had not attended university (AOR: 2.081, 95% CI: 1.256-3.449) had never sought advice from CFHNs, and that mothers who had not attended university (AOR: 1.769, 95% CI: 1.025-3.051), multiparous (AOR: 1.831, 95% CI: 1.105-3.035) and employed (AOR: 2.058, 95% CI: 1.135-3.733) mothers had never sought advice from other HPs. Understanding sociodemographic factors associated with seeking child feeding advice from HPs may inform priorities for engaging families in health promotion.

Twelve-month effectiveness of telephone and SMS support to mothers with children aged 2 years in reducing children's BMI: a randomized controlled trial.

BACKGROUND/OBJECTIVES: Few quality intervention studies have assessed whether a combined telephone and short message service (SMS) intervention to mothers is effective in reducing BMI and obesity risk behaviors of children at 3 years of age. This study aimed to assess effectiveness of telephone and SMS support in reducing children's body mass index (BMI) and obesity risk behaviors. SUBJECTS/METHODS: A randomized controlled trial (RCT) with 662 women of 2-year-old children (with the proportion of overweight and obesity being similar to the general population) was conducted in Sydney, Australia, March 2019-October 2020. The mothers in the intervention group received three telephone support sessions plus SMS messages and mailed-intervention-booklets over a 12 months period i.e., 24-26, 28-30, and 32-34 months of the child's age. Mothers in the control group received usual care and two mailed booklets on information not related to the intervention. The primary outcome was child's BMI at 3 years of age. Secondary outcomes were children's dietary and activity behaviors. All outcome measures were based on mothers' self-report using standardized tools due to COVID-19 pandemic restrictions. RESULTS: 537 (81%) mothers completed the post-intervention assessment at 3 years with only 470 (71%) children having weight and height measures. Multiple imputation analysis showed no statistically significant difference in mean BMI between the groups. Children in the intervention group were more likely not to eat in front of the TV [AOR 1.79 (95% CI 1.17-2.73), P = 0.008], more likely to meet the dietary recommendations [AOR 1.73 (95% CI 0.99-3.02), P = 0.054] and meet the activity recommendations [AOR 1.72 (95% CI 1.11-2.67), P = 0.015] than those in the control group respectively. Among those with an annual household income (

Associations of dietary and sedentary behaviours of pregnant women with their children's birth weight: findings from the CHAT trial in Australia.

OBJECTIVE: To examine the associations of pregnant women's dietary and sedentary behaviours with their children's birth weight. DESIGN: Secondary data analysis was conducted using data from a randomised controlled trial, Communicating Healthy Beginnings Advice by Telephone, conducted in Australia. Information on mothers' socio-demographics, dietary and sedentary behaviours during pregnancy was collected by telephone survey at the third trimester. Birth weight data were extracted from the child's health record book. Multinomial logistic regression models were built to examine the associations of pregnant women's dietary and sedentary behaviours with children's birth weight. SETTING: Participating families. PARTICIPANTS: Pregnant women and their children. RESULTS: A total of 1132 mother-child dyads were included in the analysis. The majority of infants (87 %, n 989) were of normal birth weight (2500 g to <4000 g), 4 % (n 50) had low birth weight (<2500 g) and 8 % (n 93) had macrosomia (≥4000 g). Mothers who ate processed meat during pregnancy were more likely to have macrosomia (adjusted risk ratio (ARR) 1·80, 95 % CI (1·12, 2·89)). The risk of macrosomia decreased as the number of dietary recommendations met by mothers increased (ARR 0·84, 95 % CI (0·71, 0·99)). Children's birth weight was not associated with mothers' sedentary time. Children's low birth weight was not associated with mothers' dietary and sedentary behaviours during pregnancy. CONCLUSION: Maternal consumption of processed meat during pregnancy was associated with an increased risk of macrosomia. Increasing number of dietary recommendations met by mothers was associated with a lower risk of macrosomia. The findings suggested encouraging pregnancy women to meet dietary recommendation will benefit children's birth weight.

Psychometric properties of the Chinese version of the Nursing Home Adjustment Scale (C-NHAS) in Central China: Classical test theory and item response theory.

Evidence for the nursing home adjustment scale (NHAS)' s applicability in less developed regions of China is still absent. Besides, there is a need to provide further validity evidence for the NHAS using modern test theory. This study aims to investigate the psychometric properties of the Chinese version of the NHAS (C-NHAS) in a sample of nursing home residents in central China. A total of 761 older adults who lived in 21 nursing homes in Hunan Province, China, were investigated from July 2021 to December 2021. The C-NHAS yielded a four-factor structure and showed good reliability and validity. The difficulty of items matched most individuals' ability, while a small number of individuals with low ability had no items for matching. The results indicated the C-NHAS is a reliable and valid instrument while the high difficulty may restrict the performance of the C-NHAS among the less educated older adults.

Association of oral status with frailty among older adults in nursing homes: a cross-sectional study.

BACKGROUND: The oral status of an individual is a vital aspect of their overall health. However, older adults in nursing homes have a higher prevalence of frailty and poor oral health, particularly in the context of global aging. The objective of this study is to explore the association between oral status and frailty among older adults residing in nursing homes. METHODS: The study involved 1280 individuals aged 60 and above from nursing homes in Hunan province, China. A simple frailty questionnaire (FRAIL scale) was used to evaluate physical frailty, while the Oral Health Assessment Tool was used to assess oral status. The frequency of tooth brushing was classified as never, once a day, and twice or more a day. The traditional multinomial logistic regression model was used to analyze the association between oral status and frailty. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated while controlling for other confounding factors. RESULTS: The study found that the prevalence of frailty among older adults living in nursing homes was 53.6%, while the prevalence of pre-frailty was 36.3%. After controlling for all potential confounding factors, mouth changes requiring monitoring (OR = 2.10, 95% CI = 1.34-3.31, P = 0.001) and unhealthy mouth (OR = 2.55, 95% CI = 1.61-4.06, P < 0.001) were significantly associated with increased odds of frailty among older adults in nursing homes. Similarly, both mouth changes requiring monitoring (OR = 1.91, 95% CI = 1.20-3.06, P = 0.007) and unhealthy mouth (OR = 2.24, 95% CI = 1.39-3.63, P = 0.001) were significantly associated with a higher prevalence of pre-frailty. Moreover, brushing teeth twice or more times a day was found to be significantly associated with a lower prevalence of both pre-frailty (OR = 0.55, 95% CI = 0.34-0.88, P = 0.013) and frailty (OR = 0.50, 95% CI = 0.32-0.78, P = 0.002). Conversely, never brushing teeth was significantly associated with higher odds of pre-frailty (OR = 1.82, 95% CI = 1.09-3.05, P = 0.022) and frailty (OR = 1.74, 95% CI = 1.06-2.88, P = 0.030). CONCLUSIONS: Mouth changes that require monitoring and unhealthy mouth increase the likelihood of frailty among older adults in nursing homes. On the other hand, those who brush their teeth frequently have a lower prevalence of frailty. However, further research is needed to determine whether improving the oral status of older adults can change their level of frailty.

Revision of brief health literacy assessment scale among the older adults and its reliability and validity test. / è€å¹´äººç®€çŸ­å¥åº·ç´ å »è¯„ä¼°é‡è¡¨çš„ä¿®è®¢åŠä¿¡æ•ˆåº¦æ£€éªŒ.

OBJECTIVES: The development and validation of the specific health literacy assessment tool for older adults is the basis for conducting the research on health literacy among older adults. The existing health literacy assessment scale for older adults in Chinese mainland has some limitations, such as too many items and poor compliance during the survey. It is necessary to develop or introduce simplified assessment tools to support large-scale surveys in the future. This study aims to modify the brief health literacy assessment scale compiled by Taiwan scholars, and to conduct the test for the reliability, validity and the measurement equivalence across gender in the older population in mainland China. METHODS: From March to April 2021, 508 older adults from Jinan, Shandong Province, China were selected by cluster sampling method to conduct a questionnaire survey using the brief health literacy assessment scale and health-promoting lifestyle profile. After 4 weeks, 83 of them were selected for retesting. SPSS 25.0 statistical software was used for descriptive analysis, item analysis, exploratory factor analysis, correlation analysis, and reliability test, and Mplus 8.0 was used for confirmatory factor analysis and gender measurement equivalence test. RESULTS: Each item of the scale had good discrimination, and there were significant differences in the scores of each item between high score and low score groups (P<0.05), and the coefficient of correlation between the scores of each item and the total score was between 0.721 and 0.891. Exploratory factor analysis extracted a factor with a characteristic root greater than 1, and the cumulative variance interpretation amount was 67.94%. The confirmatory factor analysis showed that the single factor structure fit was good [χ2/df was 2.260, the Tucker-Lewis index was 0.973, the comparison fit index (CFI) was 0.982, and the root mean square error of approximation (RMSEA) was 0.071]. The multi-group confirmatory factor analysis results showed that the brief health literacy assessment scale's configural equivalence, weak equivalence, and strong equivalence models were all accepted. The comparison results of measurement equivalence models showed that the changes of RMSEA were less than 0.015, and the changes of CFI were less than 0.01, indicating that the brief health literacy assessment scale had measurement equivalence between different gender groups. Cronbach's α coefficient was 0.945, and the test-retest reliability was 0.946. The correlation coefficient between health literacy and health-promotion lifestyles was 0.557 (P<0.05). CONCLUSIONS: The brief health literacy assessment scale has good reliability, validity, and measurement equivalence across gender, and can be used as an effective measurement tool for the health literacy of the older people in Chinese mainland.

Circulating vitamin C and D concentrations and risk of dental caries and periodontitis: A Mendelian randomization study.

AIM: This Mendelian randomization (MR) study was performed to explore the causal relationship among circulating vitamin C and D levels, dental caries, and periodontitis. MATERIALS AND METHODS: MR analyses were conducted with the inverse variance weighted (IVW) method, weighted median, MR-Egger approaches, and MR-robust adjusted profile score method to assess the causal relationships between circulating vitamin C and D concentrations and dental caries, the number of remaining natural permanent teeth in the mouth (N teeth), and periodontitis. RESULTS: We found potential causal association of circulating vitamin D concentrations with N teeth (ß = 0.085; 95% confidence interval: 0.019 to 0.150; p = .012) based on the IVW method. No significant causal relationship between circulating vitamin D levels and dental caries and periodontitis was observed. Similarly, no evidence supported a causal relationship between circulating vitamin C concentrations and the risk of dental caries, N teeth, and periodontitis. CONCLUSIONS: There is no obvious evidence suggesting a causal relationship among circulating vitamin D, dental caries, and periodontitis, drawing into question the mechanism for any association with N teeth. Additionally, there is insufficient power to detect small effects in vitamin C levels and caries and periodontitis.

Qualitative-quantitative analysis of multi-mycotoxin in milk using the high-performance liquid chromatography-tandem mass spectrometry coupled with the quick, easy, cheap, effective, rugged and safe method.

High-performance liquid chromatography-tandem mass spectrometry coupled with the quick, easy, cheap, effective, rugged and safe method was established for the qualitative and quantitative detections of 20 mycotoxins in milk. The linear range of this method was 0.01-10 µg/L and the correlation coefficients were all greater than or equal to 0.9933. At three levels of addition, the spiked recoveries ranged from 80.00 to 112.50%, relative standard deviations were 2.67-14.97%, limits of quantitation were 0.02-4.00 µg/kg, and limits of detection were 0.007-1.300 µg/kg. This developed procedure for the identification and quantitation of mycotoxins provided prospective support for quality regulation.

Detection of multiple endocrine-disrupting chemicals in milk: Improved and safe high performance liquid chromatography tandem mass spectrometry method.

Herein, an improved method for detecting the endocrine-disrupting chemicals in milk is presented, which is based on high performance liquid chromatography tandem mass spectrometry, coupled with a quick, effective, and safe method. The linearity of the proposed method was in the range of 0.05-100 µg/L, and all correlation coefficients were ≥0.9973. At three concentration levels, the spiked recoveries ranged from 77.7 to 107.5%, relative standard deviations ranged from 0.2 to 14.6%, limits of quantitation ranged from 0.1 to 40 µg/kg, limits of detection ranged from 0.03 to 13.3 µg/kg. The proposed method for the identification and quantitation of 26 endocrine disruptors present in milk is not only easy, fast, and cost-efficient but also provides a reference for the detection of various endocrine disruptors in milk and other dairy products.

Modifiable predictors of breastfeeding status and duration at 6 and 12 months postpartum.

BACKGROUND: Breastfeeding practices are determined by complex multilevel factors. This study assessed pregnant women's knowledge of breastfeeding and intention to breastfeed and investigated modifiable predictors for breastfeeding status (exclusive or any breastfeeding) and duration at 6 and 12 months postpartum. MATERIALS AND METHODS: Longitudinal data were extracted from a trial in Sydney, Australia, 2017-19. Women (n = 1155) were recruited from antenatal clinics and followed up for telephone interviews at baseline (third trimester), then at 6 and 12 months postpartum. Data collected included mothers' demographics; knowledge of breastfeeding and intention to breastfeed; work status; support from caregivers; breastfeeding environment; breastfeeding status and duration. Multiple logistic and Cox regression models were built to identify predictors for breastfeeding. RESULTS: At baseline, most mothers knew the recommendation to exclusively breastfeed until 6 months (66%) and the benefits (65%). The modifiable predictors for breastfeeding duration at 12 months included the following: mothers' knowledge of the recommendation (adjusted hazard ratio (AHR) 0.73, 95% confidence interval (CI) 0.60-0.90) and the benefits of exclusive breastfeeding (AHR 0.68, 95% CI 0.55-0.82), intention to meet the recommendation (AHR 0.76, 95% CI 0.63-0.93), and intention to breastfeed for two years (AHR 0.38, 95% CI 0.27-0.52) measured at baseline; mothers not working or studying (AHR 0.70, 95% CI 0.55-0.89), having support from other caregivers (AHR 0.64, 95% CI 0.43-0.96), and having breastfeeding women around (AHR 0.80, 95% CI 0.65-0.98) measured at 6 months. CONCLUSIONS: Support for women to meet the breastfeeding recommendations should commence during pregnancy and focus on breastfeeding education and enabling environments.

Psychometric properties of the Chinese version of the modified Yale Food Addiction Scale version 2.0 (C-mYFAS 2.0): Prevalence of food addiction and relationship with resilience and social support.

PURPOSE: This study aimed to examine the psychometric properties of the Chinese version of the modified Yale Food Addiction Scale 2.0 (C-mYFAS 2.0) and to analyze the prevalence of food addiction among Chinese college students and its relationship with resilience and social support. METHODS: A total of 1132 Chinese college students completed the C-mYFAS 2.0, BES, EAT-26, PHQ-9, GAD-7, TFEQ-18, CD-RISC-10, and PSSS. Confirmatory factor analysis was used to evaluate the factor structure of the C-mYFAS 2.0 and psychometric properties were assessed. Test-retest reliability was evaluated in a sub-sample (n = 62). Spearman correlation and logistic regression were used to examine the relationship between resilience, social support, and food addiction. RESULTS: The prevalence of food addiction according to the C-mYFAS 2.0 was 6.2%. Confirmatory factor analyses suggested a single-factor structure (comparative fit index = 0.961). The C-mYFAS 2.0 had good test-retest reliability and internal consistency (Kuder-Richardson's α = 0.824). Good convergent validity was indicated by correlations with binge eating, eating disorder symptoms, depressive symptoms, generalized anxiety symptoms, uncontrolled eating, emotional eating, and BMI (ps < 0.001). Appropriate divergent validity was reflected by no association with cognitive restraint. Finally, binge eating was significantly predicted by C-mYFAS 2.0, depressive symptoms, and eating disorder symptoms (ps < 0.001), confirming incremental validity. In addition, our study found that poorer resilience and social support were related to food addiction (ps < .001). CONCLUSIONS: The C-mYFAS 2.0 is a brief but reliable and valid screening instrument for food addiction among Chinese college students. In addition, we found that resilience and social support were negatively associated with food addiction. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Engagement, satisfaction, retention and behavioural outcomes of linguistically diverse mothers and infants participating in an Australian early obesity prevention trial.

BACKGROUND: Early obesity prevention research interventions in Australia generally expect participants to be able to communicate in English, but do not account for other languages. This study aimed to investigate engagement, satisfaction, retention and behavioural outcomes of linguistically diverse participants from a mainstream early childhood obesity prevention trial. METHODS: Healthy Beginnings is a nurse-led intervention based in Sydney, supporting families with optimal infant feeding and active play via telephone. This secondary analysis assessed participant engagement in the nurse telephone calls (call completions), satisfaction and behavioural outcomes (6- and 12-month survey data) and retention (survey completions), in the first year of life according to participants' language spoken at home (English or other language). RESULTS: Of 1155 mothers, 533 (46%) spoke a language other than English at home. Significantly fewer mothers speaking a language other than English completed the 6-month survey (79%) compared to those speaking English (84%), yet mothers speaking a language other than English who completed the program were more satisfied with the program overall. Significantly fewer mothers speaking a language other than English completed the final four nurse calls (of six) (56%-65%) compared to those speaking English (70%-80%). Adjusted odds ratios showed selected behavioural outcomes were significantly more positive for participants speaking English at home. CONCLUSIONS: Healthy Beginnings trial participants who spoke a language other than English at home had less favourable engagement, retention and behavioural outcomes compared to those who spoke English. So what? Early obesity prevention interventions should consider cultural adaptations to improve engagement and effectiveness among culturally and linguistically diverse families.

Critical cultural competence of clinical nurses in China: A cross-sectional survey.

AIM: To determine the level of critical cultural competence (CCC) among Chinese clinical nurses and explore its influencing factors. BACKGROUND: Previous research has only focused on the theoretical model of CCC and the development of assessment tools; however, no large-scale study has been conducted on the level of clinical nurses' CCC and its influencing factors. METHOD: Clinical nurses in 14 Level A tertiary hospitals (n = 3858) were surveyed using Almutairi's critical cultural competence scale (CCCS). Descriptive, univariate and multivariate analyses were performed. RESULTS: The mean score of CCC was 4.44 (SD = 0.33). Critical empowerment (M = 4.85, SD = 0.58) and critical awareness (M = 3.57, SD = 0.99) had the highest and lowest scores, respectively. Female nurses, nurses in the nursing department and nurses with higher positions had higher CCC. CONCLUSION: The CCC of clinical nurses can be strengthened through targeted training, especially considering the fact that male and low-ranking nurses who had the lower level of CCC work in different departments. IMPLICATIONS FOR NURSING MANAGEMENT: Hospital administrators should pay attention to the importance of culture and cultural differences among different countries or ethnic groups. Creating an equal and fair nursing environment and encouraging nurses to provide critical cultural nursing is important.

Correction of presbyopia. / 老视的矫治方法.

Presbyopia, a progressive visual difficulty caused by weakened physiological regulation, is one of the main causes of visual impairment in people over 40 years old. Currently, the main methods of correction of presbyopia include optical correction, surgical correction, and drug treatment, which can improve the visual nearness disorder to some extent. Optical correction is the most common way with advantages of safety, which can adjust the lens parameters at any time, while cause kinds of inconvenience in life by wearing and taking off glasses frequently. Surgical intervention, including corneal surgery, lens surgery and scleral surgery, with certain advantages and disadvantages in each operation style. New pharmaceutical agents are expected to be a new and effective method for the treatment of presbyopia, but it lacks multicenter randomized controlled trials and evidence-based medicine evidence to evaluate the safety and effectiveness.

Evaluation of reliability and validity regarding the Chinese version of Critical Cultural Competence Scale for clinical nurses. / 临床护士评判性文化能力量表的汉化及信效度评价.

OBJECTIVES: Patients from different social environments and cultural backgrounds have different nursing needs. If nurses ignore the cultural differences of patients, it is easy to lead to the strained nurse-patient relationship, affect the nursing effect and cause harm to patients. Critical cultural competence (CCC) can help nurses to meet the nursing needs of patients from different cultural backgrounds, which is beneficial to building a harmonious nurse-patient relationship and improving the quality of nursing. Almutairi, et al designed the Critical Cultural Competence Scale (CCCS) which can be used to evaluate accurately nurses' CCC. No studies have reported the development of a critical cultural competence measurement tool for nurses or the introduction of foreign scales in China. This study aims to conduct Chinese and cross-cultural debugging and test the reliability of the English version of the CCCS in order to form CCCS suitable for Chinese cultural background and provide an effective evaluation tool for investigating the current situation of clinical nurses' CCC. METHODS: This study used Brislin's back-translation model to translate and back-translation the English version of CCCS. The Chinese version of CCCS was then created through cross-cultural debugging by expert consultation and a pre-survey with a sample size of 30 clinical nurses. From August to October 2019, 580 clinical nurses were surveyed using a whole group sampling method. The participants were randomly divided into 2 groups with a 7꞉3 ratio. One group (n=406) was used for exploratory factor analysis and reliability analysis, while the other group (n=174) was used for confirmatory factor analysis. Six experts used the scale-level content validity index (S-CVI) and the item-level content validity index (I-CVI) to assess content validity. In the exploratory factor analysis, items were screened using the critical ratio method, and were tested using the KMO (Kalser-Meyer-Olkin) index, Bartlett's sphericity test, and principal component analysis. In the confirmatory factor analysis, average variance extracted (AVE), goodness of fit index (GFI), adjusted goodness of fit index (AGFI), and root mean square error of approximation (RMSEA) were used to assess the degree of fit of the constructed model. For the total scale and the 4 subscales, the Cronbach's α coefficient, split-half reliability, and retest reliability were used to assess the scale's reliability. RESULTS: The S-CVI was 0.930, while the I-CVI ranged from 0.833 to 0.944. For all items, the critical ratio exceeded 3, and the difference between the high and low subgroups was statistically significant (P<0.05). Exploratory factor analysis revealed critical knowledge subscale had a KMO value of 0.676, with the total scale and other 3 subscales all having a KMO value >0.8 and a chi-square value of 814.32 to 12 442.45 for the Bartlett's spherical test, with degree of freedom ranging from 21 to 136 (P<0.001), indicating that all items were suitable for factor analysis. The principal component analysis showed that 17, 12, 7, and 7 items were extracted from the 4 subscales, with 4, 3, 2, and 2 components whose eigenvalues were more than 1, and the cumulative variance contribution was 66.0%, 54.3%, 56.6%, and 70.2%, respectively. The confirmatory factor analysis showed that the AVE of the 4 subscales were 0.637, 0.499, 0.560, and 0.565, GFI was 0.904, AGFI was 0.863, and RMSEA was 0.076. The Cronbach's α coefficient for the total scale and subscales ranged from 0.811 to 0.878, the split-half reliability ranged from 0.707 to 0.842, and the retest reliability was 0.827. CONCLUSIONS: The Chinese version of the CCCS has good reliability and validity, and it can be used as a valid assessment tool for clinical nurses' critical cultural competence in China.

Association of short sleep with risk of periodontal disease: A meta-analysis and Mendelian randomization study.

AIM: The aim of this meta-analysis and Mendelian randomization (MR) study was to assess the association between short sleep and periodontal disease, including tooth loss and periodontitis. MATERIALS AND METHODS: The meta-analysis of relevant studies was conducted to assess the association between short sleep and periodontal disease. MR analyses were conducted with the inverse-variance-weighted (IVW) method, weighted median method, MR-Egger method, and MR-Robust Adjusted Profile Score (RAPS) method to assess the causal effect of short sleep on tooth loss and periodontitis. RESULTS: Seven cross-sectional studies involving 40,196 individuals were included in the meta-analysis. The association between short sleep and periodontal disease was not statistically significant (odds ratios (OR) =1.13, 95% confidence interval (CI): 0.99, 1.28; p = 0.076). In the MR analysis, we did not observe statistically significant causal associations of genetically determined short sleep with tooth loss (ß: -0.056; 95% CI: -0.181 to 0.068; p = 0.376) and periodontitis (ß: -0.112; 95% CI: -0.340 to 0.117; p = 0.339). CONCLUSIONS: Short sleep is not associated with the risk of periodontal disease according to current evidence. Future studies need to pay attention to the measurement of sleep duration, the choice of statistical models, and other domains of sleep health.

Associations Between Health Literacy, eHealth Literacy, and COVID-19-Related Health Behaviors Among Chinese College Students: Cross-sectional Online Study.

BACKGROUND: During the COVID-19 pandemic, the internet has significantly spread information, providing people with knowledge and advice about health protection regarding COVID-19. While a previous study demonstrated that health and eHealth literacy are related to COVID-19 prevention behaviors, few studies have focused on the relationship between health literacy, eHealth literacy, and COVID-19-related health behaviors. The latter includes not only preventative behaviors but also conventional health behaviors. OBJECTIVE: The objective of this study was to develop and verify a COVID-19-related health behavior questionnaire, explore its status and structure, and examine the associations between these behaviors and participants' health literacy and eHealth literacy. METHODS: A snowball sampling method was adopted to recruit participants to complete anonymous cross-sectional questionnaire surveys online that assessed sociodemographic information, self-reported coronavirus knowledge, health literacy, eHealth literacy, and COVID-19-related health behaviors. RESULTS: Of 1873 college students who were recruited, 781 (41.7%) had adequate health literacy; the mean eHealth literacy score was 30.16 (SD 6.31). The COVID-19-related health behavior questionnaire presented a two-factor structure-COVID-19-specific precautionary behaviors and conventional health behaviors-with satisfactory fit indices and internal consistency (Cronbach α=.79). The mean score of COVID-19-related health behaviors was 53.77 (SD 8.03), and scores differed significantly (P<.05) with respect to residence, college year, academic major, family economic level, self-reported health status, having a family member or friend infected with coronavirus, and health literacy level. Linear regression analysis showed that health literacy and eHealth literacy were positively associated with COVID-19-specific precautionary behaviors (ßhealth literacy=.149, ßeHealth literacy=.368; P<.001) and conventional health behaviors (ßhealth literacy=.219, ßeHealth literacy=.277; P<.001). CONCLUSIONS: The COVID-19-related health behavior questionnaire was a valid and reliable measure for assessing health behaviors during the pandemic. College students with higher health literacy and eHealth literacy can more actively adopt COVID-19-related health behaviors. Additionally, compared to health literacy, eHealth literacy is more closely related to COVID-19-related health behaviors. Public intervention measures based on health and eHealth literacy are required to promote COVID-19-related health behaviors during the pandemic, which may be helpful to reduce the risk of COVID-19 infection among college students.

Strong support for broad policies to prevent childhood obesity among mothers in New South Wales, Australia.

ISSUE ADDRESSED: Support for broad policies to prevent childhood obesity is not clear. This study aimed to investigate the level of support for state government health promotion policies among mothers with infants and its associated factors. METHODS: This secondary analysis of data from 1155 mothers in NSW assessed approval for six policy options derived from public health approaches to obesity. Descriptive statistics were used to show the extent of policy approval across the cohort. Logistic regression models tested associations between perceived susceptibility and perceived severity of childhood obesity and approval of each policy option. RESULTS: The proportion of mothers who felt these policy options were 'about the right amount' (56%-68%) or 'not going far enough' (24%-36%), collectively represented 89%-95% approval of government intervention. In comparison, 5%-11% felt that these policies were 'going too far'. Factors associated with their levels of support varied between each policy option, based on mothers' characteristics and perceptions of childhood obesity. CONCLUSION: These findings indicate high support for government intervention to prevent obesity among mothers in NSW and support health promotion advocacy in this area. SO WHAT?: Governments should give due consideration to implementing each of the six policy options and prioritise the implementation of restrictions on fast food advertising in publicly owned or controlled areas.
