AbstractObjective:The aim of the current study was to evaluate the accuracy of the new software eAT24 used to assess dietary intake in the National Food, Nutrition and Physical Activity Survey (IAN-AF) against urinary biomarkers: N (nitrogen), K (potassium) and Na (sodium).Design:We conducted a cross-sectional study. Two non-consecutive 24-h dietary recalls (24-HDR) were applied, and a 24-h urine sample was collected. We examined differences between estimates from dietary and urine measures, Pearson correlation coefficients were calculated and the Bland–Altman plots were drawn. Multiple linear regression was used to evaluate the factors associated with the difference between estimates.Setting:Sub-sample from the Portuguese IAN-AF sampling frame.Participants:Ninety-five adults (men and women) aged 18–84 years.Results:The estimated intake calculated using the dietary recall data was lower than that estimated from urinary excretion for the three biomarkers studied (protein 94·3 v. 100·4 g/d, K 3212 v. 3416 mg/d and Na 3489 v. 4003 mg/d). Considering 2 d of recall, the deattenuated correlation coefficients were 0·33, 0·64 and 0·26 for protein, K and Na, respectively. For protein, differences between dietary and urinary estimates varied according to BMI (β = −1·96, P = 0·017). The energy intake and 24-h urine volume were significantly associated with the difference between estimates for protein (β = 0·03, P < 0·001 and β = −0·02, P = 0·002, respectively), K (β = 0·71, P < 0·001 and β = −0·42, P = 0·040, respectively) and Na (β = 1·55, P < 0·001 and β = −0·81, P = 0·011, respectively).Conclusions:The new software eAT24 performed well in estimating protein and K intakes, but lesser so in estimating Na intake, using two non-consecutive 24-HDR.

Purpose: Purpose of this study is to evaluate the measuring consistency of central refraction between multispectral refraction topography (MRT) and autorefractometry.Methods: This was a descriptive cross-sectional study including subjects in Sun Yat-sen Memorial Hospital from September 1, 2020, to December 31, 2020, ages 20 to 35 years with a best corrected visual acuity of 20/20 or better. All patients underwent cycloplegia, and the refractive status was estimated with autorefractometer, experienced optometrist and MRT. We analyzed the central refraction of the autorefractometer and MRT. The repeatability and reproducibility of values measured using both devices were evaluated using intraclass correlation coefficients (ICCs).Results: A total of 145 subjects ages 20 to 35 (290 eyes) were enrolled. The mean central refraction of the autorefractometer was −4.69 ± 2.64 diopters (D) (range −9.50 to +4.75 D), while the mean central refraction of MRT was −4.49 ± 2.61 diopters (D) (range −8.79 to +5.02 D). Pearson correlation analysis revealed a high correlation between the two devices. The intraclass correlation coefficient (ICC) also showed high agreement. The intrarater and interrater ICC values of central refraction were more than 0.90 in both devices and conditions. At the same time, the mean central refraction of experienced optometrist was −4.74 ± 2.66 diopters (D) (range −9.50 to +4.75D). The intra-class correlation coefficient of central refraction measured by MRT and subjective refraction was 0.939.Conclusions: Results revealed that autorefractometry, experienced optometrist and MRT show high agreement in measuring central refraction. MRT could provide a potential objective method to assess peripheral refraction.

AbstractThe number of days of data required to accurately estimate usual nutrient intake of children is not well established. This study aims to calculate the variability and the number of days required to estimate usual nutrient intake in children aged 13–32 months. This cross-sectional study, which is part of the BRISA Project in São Luís, Maranhão, Brazil, involved 231 children from April 2011 to January 2013. Socio-economic and demographic data were collected using a questionnaire, and 3 non-consecutive days of food consumption were collected using a 24-h dietary recall (24HDR) survey. Intrapersonal and interpersonal variability and variance ratio (VR) were obtained for each nutrient using the Multiple Source Method® program (version 1.0.1). The number of days (d) needed was calculated using the formula proposed by Black et al. for different correlation coefficients (r) (i.e. 0·7, 0·8 or 0·9). For the vast majority of nutrients, intrapersonal and interpersonal variability values of <1 were observed, with even smaller intrapersonal variabilities, resulting in low VR (<1). More days were needed to estimate intakes of soluble fibre (12), insoluble fibre (11), total fibre (10), vitamin C (9) and PUFA (7), while fewer days were needed for energy, carbohydrate, SFA, Ca, Fe, P and Zn (all had 2 d for r 0·9). However, most nutrients required one, two or three 24HDR for r 0·7, 0·8 or 0·9.

Background. Vietnam was one of 16 countries that implemented the second round of the GATS (Global Adult Tobacco Survey) in 2015. Aims. To assess knowledge and determinants of health consequences of different types of cigarette smoking among Vietnamese adults. Methods. A cross-sectional study among adults aged 15 years combined with using 15% of the master sample from the national sampling frame of the population and housing census was conducted. Multilevel analysis using Poisson regression was undertaken. Results. Knowledge on the health consequences of cigarette smoking has not significantly improved in the GATS-2015. Adults believe that active smoking had more of an impact on health than secondhand smoking and 24.5% and 43% of them answered that smoking light and e-cigarettes, respectively, causes less harm than regular cigarettes, and 17.3% and 18.1% of adults are not aware of the difference between them, respectively. Conclusion. Household and community’s role had little impact in the adult knowledge of smoking health consequences. It is necessary to disseminate information on the “other tobacco product” and to improve public knowledge on specific health consequences, to enhance household and community’s role in conveying health education messages to individuals.

Objective. Little research is available on the predictive factors of self-efficacy in college students. The aim of the present study is to examine the role of alexithymia, anxiety, and depression in predicting self-efficacy in academic students. Design. In a cross-sectional study, a total of 133 students at Babol University of Medical Sciences (Medicine, Dentistry, and Paramedicine) participated in the study between 2014 and 2015. All participants completed the Toronto Alexithymia Scale (TAS-20), College Academic Self-Efficacy Scale (CASES), and 14 items on anxiety and depression derived from the 28 items of the General Health Questionnaire (28-GHQ). Results. Pearson correlation coefficients revealed negative significant relationships between alexithymia and the three subscales with student self-efficacy. There was no significant correlation between anxiety/depression symptoms and student self-efficacy. A backward multiple regression analysis revealed that alexithymia was a negative significant predictor of self-efficacy in academic students (B=-0.512, P<0.001). The prevalence of alexithymia was 21.8% in students. Multiple backward logistic analysis regression revealed that number of passed semesters, gender, mother’s education, father’s education, and doctoral level did not accurately predict alexithymia in college students. Conclusion. As alexithymia is prevalent in college students and affects self-efficacy and academic functioning, we suggest it should be routinely evaluated by mental physicians at universities.

Objectives: To determine the correlation of Vit D3 levels with serum ferritin in patients with anemia. Study Design: Cross Sectional study. Setting: Department of Pathology, Qazi Hussain Ahmed Medical Complex Nowshera. Period: 5th Jan 2019 to 31st Dec 2020. Material & Methods: Data entered in SPSS 25th version. Descriptive statistics was used for numerical variables. Pearson correlation was used for correlation of Vit D3 with gender. Normality of data was checked by Shapiro wilk test. Mann Whitney U test was used to show the difference of Vit D3 and ferritin levels in gender. Results: The total of 192 anemic patients with Hb<10g/dl as per definition of WHO1 were referred for ferritin level estimation with 142(74%) females and 50(26%) males. Out of total, 47 were also advised with Vit D3 level estimation with 29(61.7%) females and 18(38.3%) males. Mean with standard deviation for age was 30+9.6 years. Mean with standard Error of mean of Vit D3 was (Mean-15.5ng/ml, SE 2.19). Mean with standard Error of mean of serum ferritin was (Mean-48.2ng/ml, SE 5.90). We observed 35(74.5%) cases out of 47, as Vit D3 deficient with a count less than 20 ng/ml. We observed that 118 (61.5%) were iron deficient with serum ferritin less than 15ng/ml. Person correlation showed a statistically significant correlation of Vit D3 with ferritin (p= 0.022, r=0.7). Spearman ranked correlation showed a statistically significant correlation between the categories of Vit D3 and ferritin (p=0.022, r=0.7). Mann Whitney U Test showed no significant difference in gender groups for botht the variables (p= 0.86 &p=0.33 respectively) thus retain the null hypotheses. Conclusion: The frequency of deficiency Vit D3<20ng/ml in anemic patients was 74% while that of ferritin<15ng/ml in anemic patients was 61.5%. There is a strong statistically significant correlation of Vit D3 with serum ferritin in anemic patients with Hb<11g/dl.

Leprosy is one of the oldest chronic diseases, and similar to other infectious diseases, it causes long-term physical and social effects on the lives of patients and their families. This was a cross-sectional study conducted with 103 patients with leprosy in Mashhad in the Mehrab Khan region in March 2016. The sampling method was convenience sampling. The data was analyzed using SPSS version 19. Descriptive statistics (frequency, percentage, mean and standard deviation) and inferential tests (ANOVA, Pearson correlation, and independent t-test) were used. The results showed that the mean age of patients was 65.2±8.1 years and the mean age of developing leprosy was 15.3±7.03. There was an inverse correlation between the score of overall stigma, internal stigma, and all dimensions of quality of life that was statistically significant, except for the social dimension (r= -0.181…; P=0.067). There was an inverse correlation between the psychological dimension of quality of life and experienced stigma. The highest score of the overall quality of life was related to divorced patients with a mean score of 79.7, which was statistically significant (P=0.016) from those who were not divorced. In post-hoc test, just the difference between widow and divorced were significant regarding quality of life. According to results, there was a negative correlation between the quality of life and all aspects of stigma using the SARI tool.

ObjectivesThe difference between income quintiles in health is relatively well accepted by the general public as a measure of health inequality. However, the slope index of inequality (SII) in health reflects the patterns of all social groups, including the middle 60%, and it could therefore be considered more academically desirable. If these two measures are closely correlated, the widespread use of the difference between income quintiles in health would be better supported. This study was conducted to compare differences between income quintiles in life expectancy (LE) and healthy life expectancy (HLE) with the SII.DesignCross-sectional comparison using correlational analysis of district level income differences in LE and HLE with associated SII.SettingAll 252 subnational districts of Korea.ParticipantsA total of 342 439 895 subjects (171 287 729 men, 171 152 166 women) and 1 753 476 deaths (970 928 men, 782 548 women) between 2008 and 2014 were analysed.Primary and secondary outcome measuresDifference in LE and HLE by income quintile and associated SII.ResultsThe Pearson correlation coefficients between differences between income quintiles and the SII were generally high: 0.97 (95% CI 0.96 to 0.98) for LE in men and women combined and 0.96 (95% CI 0.94 to 0.97) for HLE in men and women combined. In most districts, the SII was greater than the difference between income quintiles.ConclusionDifferences between income quintiles were closely correlated with the SII. The widespread use of differences between income quintiles in health as a measure of health inequality may be preferable for communicating results of health inequality measurements to the public.

Background: Alfred W. Adler (1870-1937), psychotherapist and founder of the school of individual psychology, believed that education, marriage, and job play important role in human development. Higher learning is a demanding and challenging period for students that can result in high rates of psychological distress affecting their life satisfaction. Aim: The research is to study the links between family communications, perceived stress and resilience with life satisfaction among pre-university students in UPM. Method: A cross-sectional study was conducted among a sample of 310 (females 158 and 152 males) pre-university students from a public university in Malaysia. Four instruments were used in this research namely the Family Communication Scale (FCS, Olson et al., 2004), Perceived Stress Scale (PSS, Cohen et al., 1983) Resilience Scale (CD-RISC, Connor-Davidson, 2003) & The Satisfaction with Life Scale (Diener et al. 1985). The data were analyzed using independent t-test, Pearson correlation coefficients and multiple regressions. Results: The finding of this study revealed that there are simple and multiple relationships between family communications, perceived stress and resilience with life satisfaction among pre-university students. Conclusion: The research may guide university counselors to view adolescents’ life satisfaction holistically and assist them in developing preventive and intervention plans for the university new enrolled students. Also, the results will provide students with some knowledge on their life satisfaction and its effects on their future accomplishments.

Abstract Pakistan is one of the only three countries in the world with an enduring poliovirus transmission, making poliomyelitis an important health concern for Pakistan. Paralytic scoliosis is a common musculoskeletal dysfunction associated with poliomyelitis. To determine the occurrence of paralytic scoliosis a cross-sectional study was conducted at Fauji Foundation Hospital, Rawalpindi from 2015 to 2018. All patients with poliomyelitis reporting to the hospital were included, whereas patients with scoliosis but no poliomyelitis were excluded. Cobb’s angle was used to determine the severity of scoliotic curves. Pearson correlation was used to determine the correlation of Cobb’s angle with age and Independent T-test was used to determine the difference in terms of gender. Confidence interval was kept at 95%. A total of 51 patients with poliomyelitis were included in the study with a mean age of 28.58±15.07 years.

CONTEXT AND OBJECTIVE: The interconnections between quality of life and health status as assessed via questionnaires have not been thoroughly investigated. The objective of this study was to investigate a possible correlation between the constructs of general health status and quality of life as assessed by the Portuguese versions of two questionnaires recently adapted and tested in Brazil. DESIGN AND SETTING: This was a cross-sectional study in which two self-administered questionnaires were used. This investigation was conducted at healthcare services associated with the Universidade de Caxias do Sul, Brazil. METHODS: This study presents data from a sample of 120 volunteers who completed the Portuguese versions of the Personal Health Scale and the Multicultural Quality of Life Index questionnaires. Bivariate linear regression analysis and Pearson correlation coefficients were generated from the scores of the two questionnaires. RESULTS: A significant correlation between the concepts of quality of life and health status as evaluated by the Portuguese versions of both questionnaires was observed. Almost all of the health-related questions displayed strong correlations with the overall concept of quality of life. The magnitude of this correlation accounted for almost half of the observed variance. CONCLUSIONS: These findings indicate that, within this sample, health-related issues were key factors for the overall experience of wellbeing and quality of life. The similarities observed across the different groups indicate that the interrelation between health status and quality of life was homogenous, regardless of presence and/or type of ailments.
