ObjectivesTo identify spatial disparities and demographic characteristics of short stature, we analysed the prevalence of short stature collected in a nationwide health survey.SettingsData were obtained from the 2014 Chinese National Survey on Students Constitution and Health (a cross-sectional study of China). Participants came from 30 provinces, autonomous regions, and municipalities (except Tibet, Hong Kong, Macao, and Taiwan).ParticipantsThere were 213 795 Han school children between 7 and 18 years old enrolled in our study. All participants were sampled by stratified cluster.Primary and secondary outcome measuresShort stature; Chinese and WHO age-specific and gender-specific height growth references were used for short stature assessment.ResultsThe age-standardised and age–gender-standardised prevalence of short stature nationwide was 3.70% and 2.69% according to Chinese and WHO growth references, respectively. The short stature prevalence differed significantly among age groups, urban and rural areas, and regions with different socioeconomic development levels (all p<0.0001). The prevalence was 2.23% in urban versus 5.12% in rural areas (p<0.001). The prevalence was 2.60% in developed, 3.72% in intermediately developed, and 4.69% in underdeveloped regions (p<0.0001). These values were all according to China’s growth reference, but similar patterns were observed on prevalence based on the WHO reference. The spatial distribution of prevalence of short stature presented a clustered pattern. Moran’s I value was 0.474 (p<0.001) and 0.478 (p<0.001) according to the Chinese and WHO growth references, respectively. The southwest part of China showed a higher prevalence of short stature, whereas lower prevalence of short stature was observed mainly in the northeast part of China.ConclusionsThere is an appreciably high prevalence of short stature in rural, underdeveloped areas of China. There are high prevalence spatial clusters of short stature in southwestern China. This provides corroborating evidence for a tailored strategy on short stature prevention and reduction in special areas.

Objectives: To assess the severity of malocclusion and orthodontic treatment needs among 12- to 15-year-old school children of Davangere District, India, by using the Dental Aesthetic Index (DAI).Methods: A descriptive cross-sectional study was conducted among 1800 12- to 15-year-old school children of Davangere District, Karnataka, India. Talukas (administrative units in some states in India) were considered clusters. Schools were selected using simple random sampling procedures. The 300 study subjects were selected using systematic random sampling procedures. Data consisting of DAI components were recorded pro forma. The collected data were subjected to statistical analysis. The Chi-square test (X2) was used to compare malocclusion severity. The analysis of variance (ANOVA) test was used to compare the changes in DAI scores and the mean DAI scores between age groups. The Z test was used to compare mean DAI scores between the 2 sexes and between children residing in urban and rural areas.Results: Of the 1800 school children examined, 899 (49.9%) were boys and 901 (50.1%) were girls. Most of the children (79.9%) had DAI scores ≤ 25 with no or minor malocclusion requiring no or little treatment, 15.4% had DAI scores of 26–30 with definite malocclusion requiring elective treatment, 4.2% had DAI scores of 31–35 with severe malocclusion requiring highly desirable treatment, and 0.5% had DAI scores ≥ 36 with handicapping malocclusion requiring mandatory treatment.Conclusions: The majority of the children in our study (79.9%) required no or little treatment; 20.1% had definite malocclusion requiring definite orthodontic treatment.

Objective: The last two decades have witnessed an increase in health care costs due to obesity and related issues among children and adolescents. Childhood obesity is a global phenomenon affecting all socio-economic groups, irrespective of age, sex or ethnicity. The study was done to find the the prevalence of obesity and overweight and their association with socioeconomic status (SES) and the risk factors. Materials and Methods: School based cross sectional study carried out over a period of 4 months in three schools of East Delhi. The study was carried out in 629 school children of 10–18 years of age and belonging to different socioeconomic statuses in schools in East Delhi. The obesity and overweight were considered using an updated body mass index reference. A pre-tested questionnaire was used to determine the Socio-economic status and life style factors. Results: The prevalence of overweight among children was higher in middle socioeconomic status groups as compared to high socioeconomic class in both boys and girls whereas the prevalence of obesity was higher in high Socio economic status group as compared to middle socioeconomic group. The prevalence of obesity as well as overweight in low SES group was the lowest as compared to other group. Conclusion: The findings of this study suggest that the prevalence of overweight and obesity varies remarkably with different socioeconomic development levels.

Malnutrition is a major public health concern in Niger. The stunting rate in children in Niger is over 50%, one of the highest in the world. The purpose of this cross-sectional study was to examine children’s dietary diversity (CDD) and the maternal factors that impact CDD. A total of 1265 mother–child pairs were analyzed. Descriptive analysis was conducted to present maternal and child characteristics. To compare the mean scores of CDD in relation to the region, an independent sample t-test was conducted. A one-way ANOVA test was conducted to evaluate the CDD score by different age groups. A linear regression model was estimated to identify household, maternal and child factors that affect the CDD score. Our results indicate that most of the participants of our survey resided in rural areas and the majority (80.7%) of the mothers had no education. Factors such as region, children’s age, woman’s empowerment, vitamin A intake and wealth index were significant predictors of CDD (p < 0.05). The children residing in rural areas were more likely to have lower CDD scores (p < 0.05) than the children in urban areas, therefore becoming more susceptible to malnutrition.

Introduction: Blastocystis spp. is a protist found in humans. Although usually the most frequent protozoa found in stool samples of both symptomatic and healthy subjects, its pathogenic or rather opportunistic role is yet to be clearly elucidated. To attempt to fill this gap, a cross-sectional study was conducted to compare the frequency of Blastocystis spp. in HIV positive (HIV+) versus HIV negative (HIV-) individuals in four health facilities of the Center Region of Cameroon. Methodology: Stool samples were collected from 283 HIV positive and 245 HIV negative subjects and analyzed using direct diagnostic tests. Results: A total of 46 (8.7%) individuals were found infected with Blastocystis spp., including 6.7% HIV positive and 11.0% HIV negative. This species was more frequent in urban and semi-urban areas than in rural areas, but evenly distributed among genders and age groups as well as among all sectors of activity. The prevalence of Blastocystis spp. (11.3%) was higher in HIV+ patients with a CD4 count ≥ 500 cells / mm3, but no significant difference was found among HIV clinical stages. Likewise prevalence, the mean number of cysts per gram of stool was similar between HIV positive and HIV negative individuals. People infected with Blastocystis spp. showed diverse clinical signs, but only flatulence was significantly more prevalent. The frequencies of these clinical signs were not related to HIV status. Conclusion: No clear relationship links the infection with Blastocystis spp. to HIV, although its presence was associated with digestive disorder, suggesting that this parasite might not be opportunist.

Abstract Background Our main objectives were to estimate the incidence of illnesses presumably caused by SARS-CoV-2 infection during the lockdown period and to identify the associated risk factors.Methods Participants from 3 adult cohorts in the general population in France were invited to participate in a survey on COVID-19. The main outcome was possible COVID-19, defined as a sudden onset of cough, fever, dyspnea, ageusia and/or anosmia, that lasted more than 3 days and occurred during the 17 days before the survey. We used delayed-entry Cox models to identify associated factors.Results Between April 2, 2020 and May 12, 2020, 279,478 participants were invited, 116,903 validated the questionnaire and 106,848 were included in the analysis. Three thousand thirty-five cases of possible COVID-19 were reported during 62,099 person-months of follow-up. The cumulative incidences of possible COVID-19 were 6.2% (95% Confidence Interval (95%CI): 5.7%; 6.6%) on day 15 and 8.8% (95%CI 8.3%; 9.2%) on day 45 of lockdown. The risk of possible COVID-19 was lower in older age groups and higher in French regions with a high prevalence of SARS-CoV-2 infection, in participants living in cities >100,000 inhabitants (vs rural areas), when at least one child or adolescent was living in the same household, in overweight or obese people, and in people with chronic respiratory diseases, anxiety or depression or chronic diseases other than diabetes, cancer, hypertension or cardiovascular diseases. Conclusion The incidence of possible COVID-19 in the general population remained high during the first two weeks of lockdown, and decreased significantly thereafter. Modifiable and non-modifiable risk factors were identified.

Objective:Improper management of polypharmacy in community and hospital pharmacies may lead to adverse effects and drug interactions in patients of all age groups, especially children and the elderly. This study aimed to determine the scenario of polypharmacy in multiple communities in Nepal and the costs associated with them. Design: Cross-sectional study Setting:Local communities of nine districts in Nepal Participants:Total 400 patients of all age groups, who were consuming medicines and who fulfilled inclusion criteria from May 2017 to August 2018 Primary and secondary outcome measures:A semi-structured questionnaire, based on the prescription optimization method, was used for data collection. Multinomial logistic regression was performed to analyze the statistical significance of polypharmacy with the predictor variables (e.g., age, education level, occupation, diagnosis, total cost of medicines). The p-value <0.05 was considered statistically significant at 95% confidence interval. Polypharmacy cases and their economic implications were reported. Results:Eighty-one patients (20.3%) with an age group of 22-31 years with female patients (219, 54.8%) reported more polypharmacy events. There were 216 patients (54%) with prescriptions of five medicines i.e., moderate polypharmacy. Total number of medicines consumed by all 400 patients was 2269, with a mean, SD 5.67, 1.08. Total expenditure by all 400 patients was USD 3409.54 during the study period, with a mean, SD 8.66, 6.04. Both moderate and severe polypharmacy cases were non-significantly related with age, gender and total cost of medications. They had significant relationship in almost all levels of education and occupation and showed mixed type of significance and non-significance with the diagnosis of the respondents. Conclusion: Polypharmacy cases can be minimized, considering adverse drug reactions and drug interactions. Further studies are warranted in medication utilization and avoidable polypharmacy along with detailed pharmacoeconomic evaluation.

Background: Authors examined serum vitamin D status among the healthy school children belonging to the south Indian state of Kerala.Methods: A cross-sectional study, participants were recruited through medical camps organized in Thrissur and Palakkad districts of central Kerala during the months of March and April 2017. A 174 healthy school children (98 males and 76 females) aged 5-13 years were recruited for the study. The children were found to be healthy on the basis of physical examination by a Paediatrician. None of the children had any symptoms of skeletal deformities. All the children were drug-naive. Data on height, weight, skin color, food habits, physical activities and socio-economic status were recorded. A 2ml of peripheral blood samples were collected from the participants. Total vitamin D in the serum was estimated by chemiluminescence immunoassay (CLIA).Results: VDD was observed in 60.92% and insufficiency in 30.46% of the participants. Only 8.62% of the participants had normal vitamin D levels. The mean vitamin D level was 19.93 ng/ml. Males had significantly higher vitamin D levels compared to females. Factors such as age, height, weight, diet, skin color and socio-economic status did not influence vitamin D levels.Conclusions: This is the first study of vitamin D status among the school-age children of Kerala. This paper adds further evidence to the reports indicating high prevalence of subclinical VDD among children across India and calls for action.

Aim: To study the prevalence of myopia among school children in Aba, Nigeria.Methods: This cross-sectional study was conducted in public and private (primary and secondary) schools. A multi-stage random sampling technique was used for selecting participants aged between 8 and 15 years from 12 schools in Aba, Nigeria. Data were analysed for 1197 children who underwent a comprehensive eye examination. The children were divided according to the following criteria: age groups (group 1 [8–11 years] or group 2 [12–15 years]), gender (male or female), level of education (primary or secondary) and type of school (public or private). Myopia was defined as spherical equivalent refraction (SER) ≤ -0.50 D in the poorer eye.Results: The prevalence of myopia was estimated to be 2.7%. Of the 96 children with refractive error, 78.1% were uncorrected. In using logistic regression analysis, risk of developing myopia was associated with older age groups (odds ratio [OR]: 1.20; 95% confidence interval [CI], 0.16–9.11; p < 0.010) and higher level of education (OR: 1.73; 95% CI, 1.05–2.86; p < 0.030). There was no significant difference in myopia prevalence between male and female children (p = 0.89).Conclusion: Although the prevalence of myopia and overall prevalence of refractive error in school children in Aba were low, the high prevalence of uncorrected refractive error is a significant public health problem. An effective and sustainable children’s vision screening programme is needed to prevent visual impairment and blindness.
