Abstract Background Portion size is known to be a key driver of food intake. As consumed portions are often pre-planned, ‘ideal portion size’—an individual’s preferred meal size selected prior to eating—has been identified as a strong predictor of actual consumption. However, assessments of ideal portion size have predominantly relied on laboratory-based computer tasks, limiting use online. Therefore, this cross-sectional study sought to pilot test the validity of a web-based tool to measure ideal portion size. Methods In an online study (N = 48), participants responded to images of a range of foods. Each food was photographed in a series of different portions and loaded into an ‘image carousel’ that would allow participants to change the size of the displayed portion by moving a slider left-to-right. Using this image carousel, participants selected their ideal portion size. They also completed measures of expected satiety and expected satiation and self-reported their age and body mass index (BMI). A non-parametric correlation matrix was used to explore associations between ideal portion size and identified predictors of food intake. Results Supporting convergent validity of this measure, ideal portion size was significantly correlated with expected satiety (rs = .480) and expected satiation (rs = −.310) after controlling for effects of baseline hunger and fullness, consistent with past research. Similarly, supporting divergent validity of this measure, ideal portion size was not significantly correlated with age (rs = −.032) or BMI (rs = −.111,). Conclusions Pilot results support the validity of this web-based portion size selection tool used to measure ideal portion size, though further research is needed to validate use with comparisons to actual food intake.

Covid -19 is an infectious disease caused by the newly discovered strain of coronavirus. As there is no vaccine discovered, the only way to prevent the spread is through following the practice of social isolation. But prolonged isolation may also lead to psychological stress and problems. The objective of the survey was to assess the knowledge and awareness of preventive measures against Covid 19 amongst small shop owners. A web-based cross-sectional study was conducted amongst the small shop owners.  A structured questionnaire comprising 15-17 questions had been put forth to assess the Covid 19 related knowledge and perception. The shopkeepers were contacted telephonically and responses recorded. The data analysis was performed using IBM SPSS statistics. Although the majority of the population had a positive perception about the preventive measures against the Covid spread, 36% of the shopkeepers were not aware of the preventive measures against the Covid spread. This study found optimal knowledge and perception of the preventive measures against Covid spread among the shopkeepers but misinformation and misunderstanding still prevailing. The shopkeepers are crucial in the prevention of the spread of Covid 19 and educating them might aid us in the fight against Covid- 19.

Background: The magnitude of postpartum depression in Jordan is under documented, and little is known about its potential sociodemographic and clinical correlates. Purpose: The aim of this study was to explore the prevalence and risk factors associated with postpartum depression among Jordanian mothers in the first 18 months after delivery. Method: This descriptive cross-sectional study was carried out from April to June 2020 in Jordan. A web-based survey was used for recruiting eligible participants. An Arabic version of the validated self-administered Edinburgh Postnatal Depression Scale questionnaire was used to measure postpartum depression with a cut-off score of ⩾12 which indicates probable depression. Results: A total of 1,071 Jordanian women participated in the study. Of those, 567 women had postpartum depression (52.9%). Multivariate logistic regression analysis revealed that postpartum depression was significantly associated with marital conflict (OR: 4.91; 95% CI: 2.36–10.20), negative attitude from the pregnancy (OR: 0.67; 95% CI: 0.45–0.99), unplanned pregnancies (OR: 1.73; 95% CI: 1.16–2.60), lack of social support (OR: 1.93; 95% CI: 1.12–3.32), time from last delivery (OR: 0.99; 95% CI: 0.98–1.00), insomnia (OR: 0.53; 95% CI: 0.35–0.82), and depression during the pregnancy (OR: 0.51; 95% CI: 0.33–0.78). Most of the participants (65.7%) sought social support to avoid, reduce, or treat postpartum depression. Conclusions: Postpartum depression among Jordanian women was the highest in comparison to that of women in other countries in the region. Therefore, screening for the presence of depressive symptoms should be implemented during regular pregnancy care visits. Social support should be encouraged in order to avoid, reduce, or treat postpartum depression.

Abstract Background Podiatrists in New Zealand have a duty of care to assist patients in an emergency, and current cardiopulmonary resuscitation (CPR) certification is a requirement for registration. However, it is unknown how competent and confident podiatrists are in administering CPR and how they would respond in an emergency. Having a health professional who has a competent knowledge of CPR and skills in basic life support, can improve survival rates from sudden cardiac arrest. Therefore, the aim of this study was to survey New Zealand podiatrists to determine their CPR knowledge and qualifications; beliefs about the application of CPR; and perceptions of their competency in CPR. Methods This cross-sectional study used a web-based survey. Participants were New Zealand registered podiatrists with a current annual practising certificate. The 31-item survey included questions to elicit demographic information, CPR practice and attitudes, and CPR knowledge. Responses were collected between March and August 2020. Results 171 podiatrists responded to the survey. 16 % of the podiatrists (n = 28) had performed CPR in an emergency, with a 50 % success rate. Participants were predominantly female (n = 127, 74 %) and working in private practice (n = 140,82 %). Nearly half of respondents were younger than 40 years (n = 75,44 %) and had less than 10 years of clinical experience (n = 73, 43 %). Nearly all (n = 169,97 %) participants had received formal CPR training in the past two years, with 60 % (n = 105) receiving training in the past 12 months. Most respondents (n = 167,98 %) self-estimated their CPR ability as being effective, very effective, or extremely effective. Participants’ knowledge of CPR was variable, with the percentage of correct answers for CPR protocol statements ranging between 20 and 90 %. Conclusions This study provides the first insight into New Zealand podiatrists’ CPR knowledge and perceptions. Podiatrists were found to have high levels of CPR confidence but demonstrated gaps in CPR knowledge. Currently, New Zealand registered podiatrists require biennial CPR re-certification. However, resuscitation authorities in New Zealand and overseas recommend an annual update of CPR skills. Based on this study’s findings, and in line with Australia and the United Kingdom, the authors recommend a change from biennial to annual CPR re-certification for podiatrists in New Zealand. Trial registration The study was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620001144909).

Abstract Background The Frail-VIG frailty index has been developed recently. It is an instrument with a multidimensional approach and a pragmatic purpose that allows rapid and efficient assessment of the degree of frailty in the context of clinical practice. Our aim was to investigate the convergent and discriminative validity of the Frail-VIG frailty index with regard to EQ-5D-3L value. Methods We carried out a cross-sectional study in two Primary Health Care (PHC) centres of the Catalan Institute of Health (Institut Català de la Salut), Barcelona (Spain) from February 2017 to January 2019. Participants in the study were all people included under a home care programme during the study period. No exclusion criteria were applied. We used the EQ-5D-3L to measure Health-Related Quality of Life (HRQoL) and the Frail-VIG index to measure frailty. Trained PHC nurses administered both instruments during face-to-face assessments in a participant’s home during usual care. The relationships between both instruments were examined using Pearson’s correlation coefficient and multiple linear regression analyses. Results Four hundred and twelve participants were included in this study. Frail-VIG score and EQ-5D-3L value were negatively correlated (r = − 0.510; P < 0.001). Non-frail people reported a substantially better HRQoL than people with moderate and severe frailty. EQ-5D-3L value declined significantly as the Frail-VIG index score increased. Conclusions Frail-VIG index demonstrated a convergent validity with the EQ-5D-3L value. Its discriminative validity was optimal, as their scores showed an excellent capacity to differentiate between people with better and worse HRQoL. These findings provide additional pieces of evidence for construct validity of the Frail-VIG index.

AbstractLeft ventricular hypertrophy (LVH) is considered a cardiac condition with life-threatening complications. Detected LVH is a strong predictor of cardiovascular diseases and death. This condition is normally diagnosed at offices. We aimed to determine the prevalence and associated factors of electrocardiographic-LVH (ECG-LVH) among adults in a Thai rural community. A cross-sectional study was conducted in Na-Yao rural community of Thailand in 2020. A total of 638 individuals aged ≥ 20 years were interviewed using standardized structured questionnaires related to demographic information, risk behaviors, comorbidities and anthropometric measurements. LVH was determined by Sokolov-Lyon and Cornell criteria based on the collected electrocardiograms. The prevalence of ECG-LVH among adults was 6.6%. The factors independently associated with ECG-LVH were being male (AORs 2.04, 95% CI 1.05–3.98), history of diabetes mellitus (AORs 1.01, 95% CI 1.01–1.02), and hypertensive crisis ≥ 180/110 mmHg (AORs 7.24, 95% CI 1.31–39.92). However, resting heart rate was negatively associated with ECG-LVH (p < 0.05). Our data emphasized that LVH was one of the significant health problems among adults in a rural community. This condition could lead to severe complications. Thus, effective detection and public health interventions should be provided at the community level.

Background: Dietary acculturation refers to how a migrant group adopts the eating patterns of the host country. It results in changes in dietary behavior, dietary intake, and nutritional status of this vulnerable group. Aim: To study dietary acculturation of international students in Pune, India. Methods: International students from three Universities in Pune were enrolled. Information on demography, dietary behavior, and dietary intake (using a food frequency questionnaire) was recorded using an interviewer-administered questionnaire. The height and weight of the students were measured using standard, calibrated equipment. The data were analyzed using descriptive and analytical statistics. Results: A total of 100 international students from Iran, Africa, and South Korea were grouped by nationality. Considerable variation was detected in the daily number of meals consumed, skipping meals, portion size changes, packaged food consumption, and supplement intake following migration between the groups. The intake of non-vegetarian food had declined drastically for all groups. However, the specific non-vegetarian item showing the greatest change differed according to the group’s nationality. The intake of biscuits and cake had increased among all groups. African students showed an increase of 3.33 kg in body weight following migration. The intake of protein and micronutrients declined for all groups. Conclusions: This study highlights the changes in dietary behavior, dietary intake, and nutritional status of international students of different nationalities following migration to Pune, India. Thus, it emphasizes the need for nutrition interventions in international students in India.
