Cross Sectional Studies

Objective: The effect of processed foods on atopic dermatitis (AD) in adults is unclear. This study was to evaluate the association between processed foods and AD in the Chinese adult population.Design: This study included three population-based cross-sectional studies using cluster sampling by villages, institutions, or factories. Participants underwent dermatological examinations by certificated dermatologists and a food frequency questionnaire survey. A spot urine sample was collected to estimate the daily sodium intake. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were presented as the effect size.Setting: Shiyan city of Hubei province, and Huayuan, Shimen, Hengyang, Zhuzhou, and Changsha of Hunan province.Participants: Automobile manufacture workers from Shiyan of Hubei province, and rural residents and civil servants from Hunan.Results: A total of 15,062 participants, including 3,781 rural residents, 5,111 civil servants, and 6,170 workers, completed all evaluations. Compared to those hardly consumed pickles, consumption of pickles 1–3 times per week was significantly associated with AD (aOR: 1.35; 95% CI: 1.06–1.70). The intake of processed meats 1–3 times per month (aOR: 1.29; 95% CI: 1.05–1.58) and 1–3 times per week (aOR: 1.44; 95% CI: 1.11–1.87) were associated with AD dose-dependently when compared with those who rarely ate processed meats. Compared with non-consumers, the consumption of any processed foods 1–3 times per week (aOR: 1.39; 95% CI: 1.08–1.80) and ≥4 times per week (aOR: 1.41; 95% CI: 1.05–1.89) showed increased risks of AD. A positive association of estimated sodium intake with AD was also observed.Conclusion: Intake of processed foods is associated with AD in Chinese adults.

Study Population

Background About 60% of individuals with atopic dermatitis (AD) develop their first manifestation during infancy. Cow’s milk (CM) exposure is considered to be a risk factor for AD.Objective To evaluate for an association between cow’s milk exposure and atopic dermatitis in infants > 6 months of age.  Methods This cross-sectional study consisted of subjects from a previous study and new subjects recruited in order to meet the minimum required number of subjects. Our study population comprised 120 infants, born between 1 February and 30 November, 2012 in Sanglah Hospital, Denpasar. Subjects were divided into CM and non-CM groups and analyzed for their risk of AD. Subjects were included to CM group if they were fed with cow’s milk/formula  and included to non-CM group if they were breastfeed exclusively in the first six months of life. Other possible risk factors were assessed by multivariate analysis. Results One hundred twenty subjects were enrolled and analyzed (59 in the CM and 61 in the non-CM groups). The prevalence of AD was 30%. Multiple logistic regression analysis revealed a significant association between CM exposure and AD, with odds ratio (OR) 2.37 (95%CI 1.036 to 5.420; P=0.04). In addition, maternal diet including eggs and/or cow’s milk during the breastfeeding period was significantly associated with AD in infants (OR 3.18; 95%CI 1.073 to 9.427; P=0.04).Conclusion Cow’s milk exposure is significantly associated with atopic dermatitis in infants  > six months of age.

Human papillomavirus (HPV) imposes an increased risk of developing cervical, anal and oropharyngeal cancer. In the Western world, HPV infection is currently the major cause of oropharyngeal cancer. The effectiveness of HPV vaccines for oral or oropharyngeal HPV infection is yet to be determined. This study conducted a systematic literature search in Pubmed and Embase. Studies investigating the impact of HPV vaccines on oral or oropharyngeal HPV infection were enrolled. This review reports the relative prevention percentage (RPP), including a risk of bias assessment as well as a quality assessment study. Nine studies were included (48,777 participants): five cross-sectional studies; one randomized community trial study (RCT); one longitudinal cohort study; and two case-control studies. A significant mean RPP of 83.9% (66.6–97.8%) was calculated from the cross-sectional studies, 82.4% in the included RCT and 83% in the longitudinal cohort study. Further, two case-control studies that measured antibody response in participants immunized with HPV vaccines were included. Respectively, 100% and 93.2% of participants developed HPV-16 Immunoglobulin G (IgG) antibodies in oral fluids post-vaccination. Analysis of the studies identified a significant decrease in vaccine-type oral or oropharyngeal HPV infections in study participants immunized with HPV vaccines across study designs and heterogenous populations. Further, a significant percentage of participants developed IgG antibodies in oral fluid post-vaccination.

ObjectiveTo assess the level of knowledge about blood donation and associated factors in Ethiopia.DesignSystematic review and meta-analysis.MethodsBoth published and unpublished cross-sectional studies on the level of knowledge about blood donation in Ethiopia were included. Articles from different databases such as PubMed/MEDLINE, HINARI, EMBASE, Scopus, Google Scholar and African Journals Online were searched. Cochrane I2 statistics were used to check for heterogeneity. Subgroup and sensitivity analyses of evidence of heterogeneity were carried out. Egger’s test with funnel plot was conducted to investigate publication bias.ResultTwenty cross-sectional studies with a total of 8338 study participants (4712 men and 3626 women) were included. The overall nationwide level of knowledge about blood donation was 56.57% (95% CI 50.30 to 62.84). Being in secondary school and above (adjusted OR=3.12; 95% CI 2.34 to 4.16) and being male (adjusted OR=1.81; 95% CI 1.44 to 2.28) were the factors associated with level of knowledge about blood donation.ConclusionMore than half of the study participants were knowledgeable about blood donation. Sex and educational status were the factors significantly associated with level of knowledge about blood donation in Ethiopia. Therefore, there is a need for education and dissemination of information about blood donation among the general population to build adequate knowledge and maintain regular blood supply.
