Asthma Symptoms

BackgroundGlobal Asthma Network (GAN) was established in 2012 as a development to the International Study of Asthma and Allergies in Childhood to improve asthma care globally.ObjectiveTo survey asthma, allergic rhinitis and atopic dermatitis in primary and secondary school children and to investigate and evaluate its prevalence, severity, management and risk factors in Mexico.MethodsGAN Phase I is a cross-sectional, multicentre survey carried out in 15 centres corresponding to 14 Mexican cities throughout 2016–2019 using the validated Spanish language version of the GAN Phase I questionnaires. The questionnaires were completed by parents of 6–7-year-old primary school pupils (school children) and by 13–14-year-old adolescents.ResultsA total of 35 780 school children and 41 399 adolescents participated. Wheezing ever prevalence was 26.2% (95% CI 25.8% to 26.7%) in school children and 23.9% (95% CI 23.4% to 24.3%) in adolescents. The corresponding frequencies for current wheeze were 10.2% (95% CI 9.9% to 10.5%) and 11.6% (95% CI 11.2% to 11.9%). In school children, the risk factors for current wheeze were rhinitis (OR 4.484; 95% CI 3.915% to 5.134%) and rash symptoms (OR 1.735; 95% CI 1.461% to 2.059%). For adolescents, rhinitis symptoms (OR 3.492; 95% CI 3.188% to 3.825%) and allergic rhinitis diagnosis (OR 2.144; 95% CI 1.787% to 2.572%) were the most significant. For both groups, there was a negative relation with centres’ sea level altitude higher than 1500 m above mean sea level (p<0.005).ConclusionsThe most important risk factors for asthma symptoms in both age groups were the presence of rhinitis and rash symptoms or diagnosis. On the other hand, sea level altitude higher than 1500 metres was a protective factor.

Background Myopia is the leading cause of correctable visual impairment and preventable blindness worldwide. Genetic and environmental factors contribute to the development of myopia. Myopia is appearing with greater prevalence in young children. Objective This study aimed to assess the prevalence and associated factors of myopia among school children in Bahir Dar city, Northwest Ethiopia, 2019. Methods and materials A school-based cross-sectional study was conducted among school children of 6 to 18 years of age in Bahir Dar city from October to November 2019. A pretested interviewer-administered structured questionnaire was used to collect data among 634 participants using a multi-stage sampling technique from primary and secondary schools. Cycloplegic refraction was performed by optometrists for each student with 1% cyclopentolate eye drop, and subjective refraction was carried out to determine the final prescription of the students. Myopia was defined as spherical equivalent refractive error of ≥ 0.5 diopter in either eye. Data were entered into Epi Info version 7 and exported to Statistical Package for Social Sciences version 23 for analysis. Tables, frequency, and mean were used for descriptive statistics. Bivariable and multivariable logistic regression analyses were done to identify risk factors of myopia. Odds ratio with 95% confidence level was determined and variables with p–value of < 0.05 were considered as statistically significant. Results Among a total of 601 study participants, 51 (8.49%) were myopic. Age group of 10–13 years (AOR = 6.54: 95% CI = 5.56–10.86), 14–18 years (AOR = 6.32: 95% CI = 5.32–9.69), 2–4 hour per day mobile exposure (AOR = 3.69: 95% CI = 1.63–8.38), > 4 hour per day mobile exposure (AOR = 11.6: 95% CI = 4.41–30.42), near working distance of < 33 centimeter (AOR = 6.89: 95% CI = 2.71–17.56) and outdoor activity (AOR = 3.94: 95% CI = 1.87–8.31) were significantly associated with myopia. Conclusions The prevalence of myopia was high among school children in Bahir Dar city. Older age, longer duration of mobile exposure, shorter near working distance were the risk factors for the development of myopia whereas having outdoor activity was the protective factor.

<b><i>Background:</i></b> Few data are available concerning the prevalence and risk factors for allergic rhinitis (AR) in school children in Hubei Province which is located in the central part of China. This study investigated the epidemiological features of AR among school children in Hubei Province. <b><i>Methods:</i></b> A cross-sectional questionnaire survey on AR in school children was carried out in 5 cities in Hubei Province by cluster sampling from June to September 2018. Questionnaires were filled out by children and their parents jointly. The diagnostic criteria of AR were according to the SFAR. Questions from the questionnaire were used to examine the pattern of AR. Logistic regression analysis was used to assess the risk factors for childhood allergies. <b><i>Results:</i></b> The total prevalence rate of AR was 16.16%, with 24.31% (Wuhan), 4.34% (Xiangyang), 4.31% (Tianmen), 10.92% (Jingmen), and 11.42% (Huangshi), respectively. The prevalence of AR was positively correlated with gross domestic product per capita (<i>p</i> &#x3c; 0.05). Multivariate analysis revealed that male, city of Wuhan, family history of allergy, food allergy, drug allergy, air purifier, exposure to dust, living in towns or urban area before 2 years old, maternal age for 26–35 years old, and frequent application of antibiotics increased the risk of AR, while daily outdoor time for 1–2 h, daily sleeping time &#x3e;8 h, siblings, and breastfeeding for &#x3e;6 months reduced the risk significantly. <b><i>Conclusion:</i></b> We found the apparent geographic variation of children allergies in Hubei Province. Both genetic and environment factors had impacts on the prevalence of AR in school children. Public policies should specifically target at the local risk factors for different areas.

Abstract Background Schistosomiasis and fascioliasis are digenean parasitic infections and are among the neglected tropical diseases that have both medical and veterinary importance. They are found mainly in areas having limited access to safe water supply and improved sanitation. Methods A cross-sectional study was conducted to determine the prevalence of Schistosoma mansoni and Fasciola species infections and to identify associated risk factors among school children in Amhara Regional State, Ethiopia. Stool specimens were collected from 798 children (419 males, 379 females) and processed using Kato-Katz and formol-ether concentration techniques. A semi-structured questionnaire was used to collect socio-demographic and other exposure information to explore potential risk factors for the infections. Results The overall prevalence of S. mansoni and Fasciola species infections was 25.6% (95% confidence interval (CI): 22.5-28.6) and 5.5% (95% CI: 3.9-7.1), respectively. S. mansoni was present in all surveyed schools with the prevalence ranging from 12.8% (16/125; 95% CI = 5.6-20.0) to 39.7% (64/161; 95% CI = 32.2-47.2) while Fasciola species was identified in five schools with the prevalence ranging from 2.5% (4/160; 95% CI = 0.001–4.9) to 9.8% (13/133; 95% CI = 4.7–14.8). The prevalence of S. mansoni infection was significantly associated with swimming in rivers (Adjusted odds ratio (AOR): 1.79, 95% CI, 1.22–2.62; P=0.003), bathing in open freshwater bodies (AOR, 2.02; 95% CI, 1.39–2.94; P<0.001) and engaging in irrigation activities (AOR, 1.69; 95% CI, 1.19-2.39; P=0.004), and was higher in children attending Addis Mender (AOR, 2.56; 95% CI, 1.20–5.46; P=0.015 ) and Harbu schools (AOR, 3.53; 95% CI, 1.64–7.59; P=0.001). Fasciola species infection was significantly associated with consumption of raw vegetables (AOR, 2.47; 95% CI, 1.23-4.97; P=0.011) and drinking water from unimproved sources (AOR, 2.28; 95% CI, 1.11–4.70; P=0.026). Conclusion Both intestinal schistosomiasis and human fascioliasis are prevalent in the study area, affecting school children. Behaviors and access to unimproved water and sanitation are among significant risk factors. The findings are instrumental for targeted interventions.

Objectives: To study the effects of age on the olfactory function recovery of chronic rhinosinusitis patients after endoscopic sinus surgery and related risk factors. Methods: A total of 176 chronic rhinosinusitis (CRS) patients enrolled from February 2017 to October 2019 were divided into child, youth, middle-aged, and elderly groups. Their baseline data, T&T olfactory test score, visual analogue scale (VAS) olfactory score, sinus computed tomography (CT) Lund-Mackay score, and Lund-Kennedy score were compared. Based on postoperative olfactory function, they were divided into good and poor improvement groups. Results: Complication with nasal polyps, allergic rhinitis history, and sinus surgery history had significant differences among patients of different ages ( P < .05). Three months after surgery, T&T olfactory, VAS olfactory, Lund-Mackay, and Lund-Kennedy scores all rose with increasing age, with significant differences between any 2 groups ( P < .05). The improvement of postoperative olfactory function became poorer with aging ( P < .05). T&T and VAS olfactory scores had significant positive correlations with Lund-Mackay and Lund-Kennedy scores ( P < .001). Age, preoperative Lund-Mackay and Lund-Kennedy scores, complication with nasal polyps, allergic rhinitis history, sinus surgery history, and postoperative complications were risk factors for the poor improvement of postoperative olfactory function. Doctor-directed treatment was a protective factor for good improvement. Conclusions: The improvement of olfactory function of CRS patients after endoscopic sinus surgery declines with aging. Age, preoperative Lund-Mackay and Lund-Kennedy scores, complication with nasal polyps, allergic rhinitis history, sinus surgery history, and postoperative complications are risk factors for the poor improvement of postoperative olfactory function. Doctor-directed treatment is a protective factor for good improvement.

AbstractThis cross-sectional study investigated the characteristics of cervical HPV infection in Changsha area and explored the influence of Candida vaginitis on this infection. From 11 August 2017 to 11 September 2018, 12,628 outpatient participants ranged from 19 to 84 years old were enrolled and analyzed. HPV DNA was amplified and tested by HPV GenoArray Test Kit. The vaginal ecology was detected by microscopic and biochemistry examinations. The diagnosis of Candida vaginitis was based on microscopic examination (spores, and/or hypha) and biochemical testing (galactosidase) for vaginal discharge by experts. Statistical analyses were performed using SAS 9.4. Continuous and categorical variables were analyzed by t-tests and by Chi-square tests, respectively. HPV infection risk factors were analyzed using multivariate logistic regression. Of the total number of participants, 1753 were infected with HPV (13.88%). Females aged ≥ 40 to < 50 years constituted the largest population of HPV-infected females (31.26%). The top 5 HPV subtypes affecting this population of 1753 infected females were the following: HPV-52 (28.01%), HPV-58 (14.83%), CP8304 (11.47%), HPV-53 (10.84%), and HPV-39 (9.64%). Age (OR 1.01; 95% CI 1–1.01; P < 0.05) and alcohol consumption (OR 1.30; 95% CI 1.09–1.56; P < 0.01) were found to be risk factors for HPV infection. However, the presence of Candida in the vaginal flora was found to be a protective factor against HPV infection (OR 0.62; 95% CI 0.48–0.8; P < 0.001). Comparing with our previous study of 2016, we conclude that the subtype distribution of HPV infection is relatively constant in Changsha. Our data suggest a negative correlation between vaginal Candida and HPV, however, more radical HPV management is required in this area for perimenopausal women and those who regularly consume alcohol.

ObjectiveWe aimed to describe the incidence of childhood household injuries and prevalence of modifiable household risk factors in rural Ghana to inform prevention initiatives.Setting357 randomly selected households in rural Ghana.ParticipantsCaregivers of children aged <5 years.Primary and secondary outcome measuresChildhood injuries that occurred within 6 months and 200 metres of the home that resulted in missed school/work, hospitalisation and/or death. Sampling weights were applied, injuries were described and multilevel regression was used to identify risk factors.ResultsCaregivers from 357 households had a mean age of 35 years (SD 12.8) and often supervised ≥2 children (51%). Households typically used biomass fuels (84%) on a cookstove outside the home (79%). Cookstoves were commonly <1 metre of the ground (95%). Weighted incidence of childhood injury was 542 per 1000 child-years. Falls (37%), lacerations (24%), burns (12%) and violence (12%) were common mechanisms. There were differences in mechanism across age groups (p<0.01), but no gender differences (p=0.25). Presence of older children in the home (OR 0.15, 95% CI 0.09 to 0.24; adjusted OR (aOR) 0.26, 95% CI 0.13 to 0.54) and cooking outside the home (OR 0.28, 95% CI 0.19 to 0.42; aOR 0.25, 95% CI 0.13 to 0.49) were protective against injury, but other common modifiable risk factors (eg, stove height, fuel type, secured cabinets) were not.ConclusionsChildhood injuries occurred frequently in rural Ghana. Several common modifiable household risk factors were not associated with an increase in household injuries. Presence of older children was a protective factor, suggesting that efforts to improve supervision of younger children might be effective prevention strategies.

Abstract Background The changes generated in the studentś lifestyle due to the academic demands, may favour the prevalence of risk factors for non-communicable diseases as well as compromise other domains of their life. The purpose of this study was to establish the prevalence of behavioural risk factors in students of the Professional in Physical Activity and Sports program of a University in Bucaramanga, Colombia. Methods A cross-sectional study with a sample of 189 students was conducted. The students were surveyed with the first step of the STEPs questionnaire, which evaluates the behavioural risk factors for non-communicable diseases. A descriptive data analysis was performed, and Pearson tests were applied to determine the correlation between the analysed variables with a level of significance α = 0.05 using STATA 13.0. Results 80% of the participants were men. The age average was 22.7 ± 3.85 years. Regarding tobacco use, 10.1% of the participants were current smokers, while 30% smoked before. The majority of the participants (92.2%) have consumed alcohol within the past 12 months, while 69.8% consumed alcohol within the last month, with 8.7% of hazardous drinking. Concerning the diet, only 24.9% met the recommended consumption of fruits and vegetables per day. When assessing physical activity levels, only 6.3% were classified as physically inactive. Additionally, an average of 6 hours of sedentary behaviour was found, with 31.2% of excessive sedentary time. A weak correlation was found between age and academic cycle with the amount of physical activity at work (r = 0.24), (r = 0.18) and with sedentary time (r = -0.28), (-0, 32). Conclusions Although the prevalence of tobacco consumption was slightly higher than the national average, the students showed a lower prevalence of behavioural risk factors than the general population. However, it is necessary to promote strategies aimed at the control and prevention of these risk factors. Key messages Being a student of a program focused on physical activity and sport, can behave as a protective factor against the most prevalent risk factors in university life. It is necessary to implement more strategies centred on making students aware of the importance of the maintenance and improvement of their lifestyles in accordance with their professional profile.
