<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.

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.

Abstract Objective: The aim of this cross-sectional study was to determine the prevalence, infection intensity and associated risk factors of intestinal schistosomiasis among primary school children in Lira district, Uganda. The study was conducted among 532 primary school pupils aged 6-16 years from eight randomly selected primary schools (March-May 2017). Stool samples were collected and examined for schistosomiasis using Odongo-Aginya method. Data on socio-demographic characteristics and risk factors were obtained using questionnaires. Results: The overall prevalence of Schistosoma mansoni was 35.7% indicating a moderate infection. Both males and females were equally affected with S. mansoni . Ogur sub county had highest prevalence (42.1%) than others. Akangi and Akano primary schools both had highest (21.1%) prevalence compared to the others. Individuals aged 14-16 and 10-14 years had heavy infections (mean epg) of 600 and 565 eggs, respectively than those aged 6-9 years. With regard to risk factors, source of drinking water, sub-county location and primary school were associated with infection. Participants who fetch water from spring (85,44.7%) had higher infection than those who fetch from other sources. The study recommends provision of safe water, periodic treatment of school-aged children with praziquantel and public health education to reduce prevalence of S. mansoni .

Rheumatic Heart

Abstract Background: Rheumatic heart disease (RHD) is the most common acquired heart disease occurring in children and adolescents. RHD is associated with significant morbidity and mortality particularly in low and middle- income countries (LMICs) where the burden is estimated to be higher compared to high income countries. Subclinical RHD is the presence of valvular lesion diagnosed by echocardiography in a person with no clinical manifestation of RHD. This study aimed at determining the prevalence, types and factors associated with subclinical RHD among primary school children in Dar Es Salaam, Tanzania.Methods: We conducted a cross-sectional, descriptive community-based study which recruited primary school children from February to May 2019. A standardized structured questionnaire was used to collect demographic data and information related to prior history of upper respiratory tract infections (URTIs). Anthropometric measurements were taken and chest auscultation and echocardiographic screening were done to all study participants. World Heart Federation echocardiographic classification was used to define the types and prevalence of subclinical RHD. Results: A total of 949 primary school children were enrolled with females being predominant (57.1%). The prevalence of subclinical RHD was 34 per 1000. All the participants had mitral valve disease only whereby 17 had definite disease and 15 had a borderline disease. The associated factors for subclinical RHD were older age of more than 9 years (OR 10.8, 95% CI 1.4-82.2, P=0.02) having three or more episodes of URTI in previous six months (OR 21, 95% CI 9.6-46, P=0.00) and poor hygiene (OR 3, 95% CI 1.3-6.8, P=0.009) Conclusion: Subclinical RHD as detected by echocardiographic screening is prevalent in primary school children, uniformly affects the mitral valve, and is associated with potentially modifiable risk factors. Children with a history of more than three episodes of URTI in six months may represent a particularly high-risk population that should be targeted for RHD.

Helminth Infections

Intestinal helminthiasis associated with malnutrition in children remains endemic in developing countries despite considerable efforts at control. This study was carried out to determine the current prevalence status and the risk factors associated with intestinal helminth infections among primary school children in Ibadan. A cross-sectional study was undertaken among 5-16 year old pupils, from 7 primary schools in Ibadan, Oyo State. Microscopic examination of stool for ova was carried out using a formol-ether concentration technique. Predisposing risk factors were determined from questionnaire data while anthropometric indices consisting of weight, height and age were the measured indicators of the nutritional status. Of the 485 pupils examined, 187(38.6%) had helminth infections and the parasites identified were Ascaris lumbricoides (35.9%), Strongyloides stercoralis (12.4%), hookworm (8.5%), Enterobius vermicularis (4.9%), Schistosoma mansoni (3.5%) and Trichuris trichiura (0.4%). More male pupils (52.9%, p = 0.05) than females (47.1%) had infections. Pupils aged between 9-12 years (p = 0.02) had highest (49.2%) infection rates. Infections were recorded in 13(18.57%) of 70 pupils treated with levamisole by the local health centres 2 weeks prior to this study. Wearing of footwear, parent’s occupation, drinking water sources, family size and toilet type were risk factors significantly associated (p<0.05) with infection in this study. The  overall prevalence of wasting, stunting and underweight were 24.4%, 28.8% and 7.8% respectively, there was however, no statistical relationship (p>0.05) between the prevalence of infection and malnutrition. Intestinal helminthiasis is still prevalent in schoolchildren despite targeted  chemotherapy. It is therefore suggested that chemotherapy should include all children in the communities along with continuous enlightenment to ensure the disruption of parasite transmission. Keywords: Intestinal helminths; school children; malnutrition; Ibadan; chemotherapy.
