Background: In recent years, there was a significant increase in myopia incidence worldwide. However, it is still not clear how it affects Spanish children. Since 2016, this research team analyzed myopia prevalence and risk in 9668 children aged between 5 and 7 years. It was shown that the prevalence rates increased from 16.8% in 2016 to 20.4% in 2019. The objective of this study is to update the prevalence rate of myopia in Spain in 2020 and analyze the risk and prevention factors of myopia. Methods: The participants underwent an optometric examination, and a questionnaire on their lifestyle, family history, and geographical origin was carried out. Finally, data were analyzed using the SPSS version 27 program. Results: 1601 children from various Autonomous Communities of Spain were examined. In 2020 the myopia rates did not increase compared to 2019 (p < 0.05), although the number of hyperopes decreased and the number of emmetropes increased. Regarding age, the prevalence of myopia increased progressively over the years (p < 0.001). There was no association between gender and myopia (p > 0.05). There was a link between the time spent in near vision and family history with the prevalence of myopia (p < 0.05). Conclusions: The prevalence of myopia in Spain in children between 5 and 7 years old increased significantly between 2016 and 2020.

Tuberculosis Prevalence

In recent years, healthcare has attracted much attention, which is looking for more and more data analytics in healthcare to relieve medical problems in medical staff shortage, ageing population, people living alone, and quality of life. Data mining, analysis, and forecasting play a vital role in modern social and medical fields. However, how to select a proper model to mine and analyze the relevant medical information in the data is not only an extremely challenging problem, but also a concerning problem. Tuberculosis remains a major global health problem despite recent and continued progress in prevention and treatment. There is no doubt that the effective analysis and accurate forecasting of global tuberculosis prevalence rates lay a solid foundation for the construction of an epidemic disease warning and monitoring system from a global perspective. In this paper, the tuberculosis prevalence rate time series for four World Bank income groups are targeted. Kruskal–Wallis analysis of variance and multiple comparison tests are conducted to determine whether the differences of tuberculosis prevalence rates for different income groups are statistically significant or not, and a novel combined forecasting model with its weights optimized by a recently developed artificial intelligence algorithm—cuckoo search—is proposed to forecast the hierarchical tuberculosis prevalence rates from 2013 to 2016. Numerical results show that the developed combination model is not only simple, but is also able to satisfactorily approximate the actual tuberculosis prevalence rate, and can be an effective tool in mining and analyzing big data in the medical field.

INTRODUCTION: Estimate the prevalence of Mansonella ozzardi infection and calculate the parasitic infection rate (PIR) in simuliid black flies in the municipality of Lábrea, State of Amazonas, Brazil. METHODS: Prevalence was measured using the thick blood smear method collected from the fingers and was related to age, sex and occupation. Simuliidae were collected with a suction apparatus, then stained with hematoxylin and dissected to verify the PIR. RESULTS: The average prevalence rate of M. ozzardi among the 694 individuals examined was 20.7%. Infection was higher in men (27.6%) than in women (14.3%) (p < 0.001) and occurred in most age groups, with the highest prevalence in the following age groups: 38-47 (40%), 48-57 (53.1%) and >58 (60.5%). The highest prevalence rates were observed in the retired (64%), followed by farm workers (47.1%). Infection by M. ozzardi was only identified in Cerqueirellum amazonicum (Simuliidae) with a PIR of 0.6%. CONCLUSIONS: This study showed a high prevalence of M. ozzardi in the riverine communities of Lábrea due to the lack of policies regarding the treatment of microfilaremic individuals in the region and an abundance of competent vectors for M. ozzardi.

Lifestyle Risk

Background. Diabetes is increasing by 3.09% per year in males and 1.92% in females. Lifestyle risk factors are related to diabetes. The aim of this work is to highlight within EU-28 countries the distribution percentages of some lifestyle risk factors and some components of diabetes health care. Methods. A literature search was conducted to highlight the presence of diabetes registries, which are fundamental tools for disease surveillance and health planning; the presence of a national diabetes plan (NDP); the care setting; and methods used for reimbursement of drugs, devices, and coverage of any comorbidities associated with diabetes. A multiple correspondence analysis (MCA) was carried out to evaluate the possible associations between the variables considered. Results. The highest percentages of diabetes (>10%) are registered in Bulgaria, Malta, and Hungary. Concerning the prevalence of overweight, no European country shows overall percentages of less than 50%. Regarding obesity, 57% of countries show prevalence rates of 25%. The record for physical inactivity belongs to Malta, with 45% of individuals being inactive. The percentage of physical inactivity for females is higher than for males across Europe. In total, 57% of the countries have an insurance-based health system, while 12 countries have public national health systems. Further, 57% of countries have an NDP, while 42% of the EU countries have established a prevalence register for diabetes. Conclusions. Prevalence rates for type 2 DM in the range of 8–9% are noted in 50% of EU-28 countries. In total, 21 out of EU countries show a high prevalence rate for overweight, while 7% of EU-28 countries have an obesity prevalence rate of 25%. Diabetes treatment is entrusted to general practitioners in most countries. The results of this work highlight the differences between countries, but also between genders.

Background: Leprosy, or Hansen’s disease, is a chronic, infectious disease caused by Mycobacterium leprae. It remains one of the leading causes of deformity and physical disability.Objective: We analysed laboratory records to assess trends in prevalence rates and case detection rates (CDRs) in Rwanda. Methods: A retrospective review of detected leprosy cases from the records of the Rwanda National Reference Laboratory over a 17-year period (1995–2011) was conducted. Skin biopsy samples were analysed microscopically using Ziehl-Neelsen staining technique to identify M. leprae.Results: Cumulatively, 266 suspected cases were reported between 1995 and 2011. Of the suspected cases, 77 (28.9%) were laboratory confirmed as having leprosy. Among detected cases, 59 (76.6%) were men and 18 (23.4%) women. The male:female ratio was 3:1. There were 77 registered leprosy cases over the 17-year period of the study, and the prevalence rate was 0.005 per 10 000 population. A gradual decrease in the prevalence rate was observed from 0.015 per 10 000 population in 2003 to 0.003 per 10 000 population in 2010. From 1995 to 2011, the CDR did not exceed one per 10 000 population.Conclusion: This laboratory review demonstrates a declining trend in prevalence rates and CDR during the period of the study. Early case detection and a sustainable leprosy control programme remain the cornerstones of reducing the physical and socio-economic burden of leprosy in Rwanda.

Objectives. To compare the differences of epidemiology analysis in population birth defects (BDs) between the rural and urban areas of Hunan Province in China. Methods. The data of population-based BDs in Liuyang county (rural) and Shifeng district (urban) in Hunan Province for 2014–2018 were analyzed. BD prevalence rates, percentage change, and annual percentage change (APC) by sex and age were calculated to evaluate time trends. Risk factors associated with BDs were assessed using simple and multiple logistic regression analyses. Results. The BD prevalence rate per 10,000 perinatal infants (PIs) was 220.54 (95% CI: 211.26-230.13) in Liuyang and 181.14 (95% CI: 161.18-202.87) in Shifeng. Significant decreasing trends in BD prevalence rates were noted in the female PIs ( APC = − 9.31 , P = 0.044 ) and the total BD prevalence rate in Shifeng ( APC = − 14.14 , P = 0.039 ). Risk factors for BDs were as follows: rural area, male PIs, PIs with gestational age < 37 weeks, PIs with birth weight < 2500   g , and migrant pregnancies. Conclusions. We should focus on rural areas, reduce the prevalence of premature and low birth weight infants, and provide maternal healthcare services for migrant pregnancies for BD prevention from the perspective of population-based BD surveillance.

Abstract Gouramy is one of the consumption of freshwater fish that have high economic value. Gouramy is a freshwater fish that have long been known and cultivated. Gouramy has many features including less demanding requirements for life, except that carp have slow growth. In maintenance appeared several constraints, such as illness. One possible cause is parasites. This research is aimed to know both the kind and the prevalence of gouramy gastrointestinal worms in Ngrajek Village Magelang Central Java. This research used survey methods through sampling at the site directly. Sample was taken once for 48 gouramy from four sites by using with fish size 10-15 cm. The main parameters of the research is the kind and prevalence degree of worms were found in the gastrointestinal of gouramy in the Ngrajek Magelang Central Java, while the supporting parameters in this research are water quality such as pH, temperature, dissolved oxygen (DO), and ammonia. The result of this research showed that from 48 gouramy from four sites, there was four samples that positively infected by gastrointestinal worms. The prevalence rate of gouramy infected with worms in the gastrointestinal for A location is 12.5%, for B location is 13.3%, for C location is 0%, and for D location is 10%. Worms prevalence rates are found in the gastrointestinal consists of Echinorhynchus 6.25%, Neoechinorhynchus 2.08% and Pallisentis 2.08%. Overall prevalence of gouramy infected with worms in the gastrointestinal in Ngrajek Village Magelang Central Java is 8.33%.

AbstractObjectiveTo estimate the association strength of dietary behaviour and sedentary habits in relation to childhood obesity in Spain.DesignA matched case–control study was carried out using data collected by sentinel network paediatricians in general practices.SettingFive Spanish autonomous communities.SubjectsCases were 437 children (2–14 years old) with BMI >95th percentile according to Spanish reference tables. Controls were 751 children (2–14 years old; two paired per case) with BMI <84th percentile. Data were collected in two phases: individual (questionnaires filled in by sentinel paediatricians) and family (self-administered questionnaires filled in a family environment). Crude OR and adjusted OR (ORc and adj OR) for the given variables were calculated using a simple and multiple conditional logistic regression analysis.ResultsThe factors with the greatest effect on obesity were family history of obesity: both parents (adj OR = 11·2), mother but not father (adj OR = 9·1), father but not mother (adj OR = 6·1), siblings (adj OR = 2·7); and eating between meals (adj OR = 2·5) and consumption of sweets and soft drinks >2 times/week (adj OR = 2·0). The highest protection effect was found for five meals per day (adj OR = 0·5), the regular consumption of breakfast (adj OR = 0·5) and for eating fruit for dessert (adj OR = 0·6). Factors related to sedentary habits did not appear as noteworthy.ConclusionsWe have determined the association between certain dietary behaviour and family history with childhood obesity in several Spanish regions.

The Impact

The rising prevalence rate of obesity in the United States has accentuated concerns about obesity-related problems as a major public health issue, which has motivated widespread efforts to increase public knowledge and to motivate individuals to change their relevant behaviors. Although health campaign messages commonly include information about prevalence rates for obesity, the impact of obesity labeling and prevalence rate descriptions in such messages has been overlooked by researchers. This online framing experiment fills the research gap by investigating the effects of obesity labeling (disease vs. body type) and prevalence statistics (prevalence rates of obesity, extreme obesity, combined overweight–obesity, or no prevalence information). Our findings suggest that obesity perceptions deviate from reality and that participants use framed cues in the health message as reference points when making judgments related to the nature and prevalence of obesity. Moreover, this study shows that even accurate information might lead to inaccurate perceptions as a result of framing, and perceptions of the nature and prevalence of obesity mediate the effects of framing on behavioral intentions. Implications for obesity framing and the design of public health messages are discussed.

Potential Risk Factors

High prevalence rates of type 2 diabetes are being observed in native Canadian communities. It is believed that native populations have a higher prevalence rate of vascular complications than nonnatives. The Southern Alberta Study of Diabetic Retinopathy (DR) examined the prevalence and incidence of DR and associated metabolic abnormalities in native and nonnative subjects. Prevalence rates of DR in type 2 diabetic native and nonnative subjects were identical, with a prevalence rate of 40%. Native subjects with retinopathy, however, tended to have more advanced changes of retinopathy compared to the nonnative subjects. Key factors such as A1c, blood pressure, duration of diabetes, and lipid values were not significantly different between the two cohorts. These data indicate that ethnicity does play a role in the development and severity of DR but potential risk factors that may affect the development of retinopathy are not significantly different between native and nonnative groups.
