“…This may be considered as limitation of the study. In addition, the study questionnaire contained sensitive questions, which may have caused social desirability bias due to underreporting of high-risk behavior [ 39 ]. Blood sampling can be seen as unpleasant by some, and may have been a deterrent to study participation [ 40 ].…”

Russia had a high incidence of hepatitis B virus (HBV) infection before the vaccination campaigns of 1997, 2001, 2007, which targeted newborns, adolescents, and adults, respectively. The aim of our study was to assess the prevalence of serological markers of HBV infection, associated factors, and vaccination status among young adults in Arkhangelsk, Northwest Russia. In this cross-sectional, population-based study, we used a quota sampling method to recruit 1243 adults aged 18–39 years. Participants completed a self-administrated questionnaire and were tested for hepatitis B markers. Associations between positivity for markers and selected sociodemographic and behavioral factors were studied by logistic regression. 10.9% of our participants were positive for at least one marker of hepatitis B, 1.2% were positive for HBsAg, and 42.1% were negative for all markers. In multivariable logistic regression analyses, age 30–34 years; lack of self-reported vaccination; and having ≥2 sexual partners in the last 6 months were associated with positivity for markers of hepatitis B. Hepatitis B vaccination was confirmed in 46.9% of participants. Although half of our study sample was vaccinated, four in 10 were still susceptible to infection and more than one participant in 100 showed evidence of an active infection.

“…Participants took part in a population-based cross-sectional study using cluster sampling. Sample size for a cross-sectional study was calculated using Epi Info software [19]. A sample size of 402 in the smallest group is sufficient to produce a two-sided 95% exact confidence interval with a precision of 5% for the expected prevalence of malnutrition of 50%.…”

(1) Background: Vietnam is a multiethnic country undergoing rapid economic development, the improvement in nutritional status in preschool children is not equally shared by all ethnic groups; (2) Methods: A cross-sectional study was performed from September–December 2018 on 16,177 children aged 24–60 months representing Kinh (n = 14421), Muong (n = 1307) and Tay (n = 449) ethnic groups. Prevalence of malnutrition, overweight, obesity and anthropometric indices were compared across ethnic groups, using WHO 2006 child growth standards; (3) Results: The prevalence of malnutrition among children of Kinh, Muong and Tay origins was 14.7%, 34.3% and 43.2%, respectively. The corresponding data for overweight was 5.5%, 2.7%, 2.2% and for obesity 2.8%, 0.8% and 0.4%, respectively. The prevalence of stunting remained the highest in three subtypes of malnutrition in all ethnic groups. Kinh children were heavier and taller than the other groups, while Muong children were taller than Tay children (p-value < 0.001); and (4) Conclusions: Malnutrition remains a major public health issue among children of minor ethnicities while overweight and obesity is an emerging challenge for the Kinh ethnic group. The results imply that a community-based intervention should be specific to ethnicity to reduce the gap in nutritional status between ethnic groups in Vietnam.

“…In the present study, the caregiver burden was considered a dependent variable, and other variables (such as depression, anxiety, stress, and other demographic variables) were assumed as independent variables. Then, the relationship between predictor variables and the caring burden was examined using multivariate regression analysis with a two‐sided significance level of 0.05 26 . Data were analyzed using the Statistical Package for the Social Sciences version 26.…”

Background and Aims Coronavirus disease 2019 (COVID‐19) has profoundly affected millions worldwide, including family caregivers of COVID‐19 patients, in terms of caregiver burden and psychological distress. The present study aimed to evaluate the care burden and psychological distress among family caregivers, caring for a family member with COVID‐19. Methods The present study was performed with a cross‐sectional design in the Shahroud community, northeast Iran using the convenience sampling method. A total of 297 family caregivers of COVID‐19 patients were assessed using self‐report scales including the depression, anxiety, and stress scale‐21 and the Zarit burden interview to assess the symptoms of psychological distress (depression, anxiety, and stress) and caregiver burden. Data were analyzed using descriptive and inferential statistics (multivariate regression analysis). Results Factors such as self‐reported symptoms of depression (β = 0.920, p < 0.001) and anxiety (β = 0.712, p < 0.02) were significantly predicted care burden. Variables such as lower levels of education of the family member and caregivers and also the relationship between the caregiver and family member were additional predictive factors that aggravated the care burden. Conclusion Caregivers of a family member with COVID‐19 suffer significant levels of care burden that also results from psychological distress such as depression and anxiety. Therefore, appropriate psychoeducational interventions are highly recommended.
