The rural population comprises almost 70%. Approximately, Bangladesh has more than 23,500 high schools. There has been no published data on the profile of illness commonly observed among the high school children. The aims of the study were a) to determine a profile of common illness among the students of rural high schools; b) to assess the nutrition status related to socio-economic class and c) to find out the correlations between anthropometry and blood pressure and between anthropometry and blood glucose status. Methods: The study was conducted in purposively selected high schools in Santhia thana under the district of Pabna. Local leaders and the school teachers volunteered to communicate the study objectives and investigation details to the eligible students. The teachers prepared the list of participants. All the willing participants were advised to attend the investigation site in the morning in a fasting state. Each participant was interviewed. Socio-demographic and clinical history was taken. Investigations included anthropometry – height (ht), weight (wt), waist- and hip-circumference (waist, hip). Adiposity indices namely body mass index (BMI – wt in kg/ht in met. sq.), waist/hip ratio (WHR) and waist/ht ratio (WHtR) were calculated. Resting blood pressure was taken. Clinical examination (general and systemic) was done. Fasting blood glucose (FBG) was estimated using glucometer strip and blood grouping by test kit. Test kit was also used for detection of urinary protein. Results: From six schools, 1069 students (boys/girls = 392/677) of age 10 to 19 years participated in the study. The participants from middle class family were 52.7% and upper were 14.4%. Their mothers were mostly housewives (95.5%) and only 16% had academic education of ten years or more. The mean (± SD) values of BMI, WHR, WHtR and FBG were 18.2 (± 2.9), 0.81 (± 0.07), 0.43 (± 0.05) and 5.26 (± 0.45) mmol/L respectively. Adiposity was significantly higher in upper socio-economic class than the middle and lower class, though no differences were observed in blood pressure and blood glucose level. Of the illnesses, the most common were sinusitis (21.4%), tonsillitis (13.3%) and toothache plus dental caries (10.7%). Conclusions: The most common illnesses were sinusitis, tonsillitis and dental caries. Anthropometric measures indicated that adiposity was not uncommon in rural children. Though adiposity was found higher among the upper than the lower socio-economic class, blood pressure and blood glucose level showed no difference indicating equal risk of non-communicable diseases (NCDs) irrespective of socio-economic class. These findings envisage that the existing status of child health might lead to NCDs in adult life. We suggest adiposity, blood pressure and blood glucose status of a high school cohort may be prospectively followed for eventual future health events. IMC J Med Sci 2020; 14(2): 007.

Email: tanjima1982@gmail.com   Introduction There were substantial number of studies that addressed health of children, adolescents and adults [1–5]. Some observed nutritional trend from 1975 to 2016 [1] and some found the childhood adiposity [3,6]. But there are very few studies conducted on illness commonly encountered by school children in rural communities of Bangladesh. There has been no published data neither in rural nor even in the urban communities on illness nature of secondary schools. This study was taken to determine the nature and extent of illnesses commonly affecting rural school children. Additionally, the study investigated the association between a) nutrition (adiposity) and socio-economic class, b) adiposity (BMI, WHR, WHtR) and fasting blood glucose (FBG) status and c) adiposity and blood pressure (SBP - systolic blood pressure, DBP - diastolic blood pressure).   Methods The protocol was approved by the Ethical Review Committee of Bangladesh Diabetes Somity (BADAS). Site selection: The study was purposively conducted at six selected schools of Santhia thana under Pabna district. These schools enroll the children from remote villages not connected with roads. Most of the children attend school on foot and in groups. The local elected body of Vulbaria Union Council (UC) under Santhia was communicated. The UC members agreed to cooperate. They suggested the names of schools. The study team discussed the study procedure (clinical history, anthropometry, blood pressure, clinical examination, fasting blood glucose) in detail with the school teachers. The teachers agreed to volunteer to communicate with the students and informed them the procedural details. The students who showed their interest to participate in the study were enlisted by the respective class teachers. Enlistment of participants: The school teachers made the list of willing participants. The students of class five to class ten were considered eligible. The study team discussed with the participants about the objectives and stepwise investigation procedure before the day of investigation. The printed questionnaire sheet was explained to the participants. They were advised to attend the school campus in the next morning in fasting condition. Investigations: Investigations included interviewing, anthropometry, blood pressure measurement, clinical examination, estimation of blood glucose, determination of blood grouping and proteinuria. Each participant was interviewed with the help of the class teacher on: a) clinical history (present illness, medication if any, past illness and treatment); b) mothers’ education and occupation; c) family income and number of family members for assessment of social-economic class. After completion of the interviewing session each student was investigated for a) anthropometry (height, weight, waist- and hip-circumference; b) blood pressure (SBP, DBP); c) fasting blood glucose using glucometer. The anthropometry measurements, blood pressure and fasting blood glucose were determined as cited in the previous study [7]. Finally, blood grouping was done using blood grouping test kit and a semi-quantitative dipstick test kit was used for detection of proteinuria. Then every participant was examined clinically. Both general and systemic examinations were done by the two physicians of the team. General examination determined any gross deformity, anemia, jaundice and edema. Systemic examination included alimentary, respiratory, cardiovascular and musculoskeletal system. Presence of abnormalities of vision (finger count and color), ear (discharge), nose (polyp, septal deviation), throat (tonsils), oral cavity (ulcer, spongy gum), teeth (decay/caries) and skin (scabies, ringworm, pigmentation) were sought. Statistical analyses: The socio-demographic data were presented in percentages. The illness prevalence data were also presented in percentages. Unpaired t-test was applied to compare the characteristics between boys and girls. All the quantitative variables were shown as – a) mean with standard deviation, b) mean with 95% confidence interval (CI). Comparisons of BMI, WHR, WHtR, SBP, DBP and FBG are shown according to social class using ANOVA.   Results A total of 1069 students (boys/girls = 392/677) volunteered the study. The mean age of participants was 13.5 ± 1.47 years. Socio-demographic variables of the participating students are shown in Table-1. More than half of the participants were from the middle and less than a third were from the upper socio-economic class. Almost a third of their mothers were illiterate. More than a half of the mothers had no access to academic education though they knew how to put their signature. Only 3.4% mothers had graduation equivalent to 12 or more years of schooling. As regards mothers’ occupation, almost all were housewives (95.5%). Very few had employment at local rural non-government organization (NGOs). The mean family size of the children was 4.7 (95% CI: 4.63, 4.79).   Table-1: Socio-demographic characteristics of the participants (n = 1069) of school children   Table-2 illustrates the biophysical characteristics of all participants and compares these variables between boys and girls. They were the students of academic class from VI (6th) to X (10th). The mean (± SD) of age was 13.5 (± 1.47) (y); and their height, weight, waist-girth and hip-girth were 153 (± 8.96) cm, 43.2 (± 9.10) kg, 65.3 (± 7.78) cm and 80.4 (± 7.76) cm, respectively. The comparisons between boys and girls showed, despite significantly higher age in the boys, the girls had significantly higher BMI, SBP and DBP; whereas, the boys had significantly higher WHR and FBG.   Table-2: Characteristics of total participants (n = 1069) including comparisons between boys and girls Table-3: Correlations among biophysical variables controlling for age and sex   The investigated biophysical characteristics (age, height, weight, waist, hip, BMI, WHR, WHtR, pulse, SBP, DBP, FBG) were put on view according to sex for each academic class in Table-4a, 4b and 4c. The values were displayed in mean with 95% confidence interval (CI).   Table-4a: The biophysical characteristics are shown according to sex by academic class (mean with 95% CI) Table-4b: The biophysical characteristics are shown according to sex by academic class (mean with 95% CI)   Table-4c: The biophysical characteristics are shown according to sex by academic class (mean with 95% CI)   Table-5 demonstrates the values of the anthropometry at 15th, 85th and 95th levels for possible lower and upper limits of nutrition and adiposity. Likewise, the values of SBP, DBP and FBG at the same levels (15th, 85th and 95th) may be used to assess the trend of metabolic outcomes related to non-communicable diseases.   Table-5: Anthropometric measures, blood pressure and fasting blood glucose levels at 15th, 85th, 95th percentiles are shown separately for male and female students   The complaints or illnesses presented or observed are shown in Table-6. Of the otolaryngologic (ear, nose and throat) illnesses, sinusitis and tonsillitis were the most common complaints or illnesses. Alimentary system including orodental hygiene, though thought to be the most common, only a total of 18% were observed; and of these, tooth decay (dental caries) was the highest (10.7%). Only 711 participants were tested for the presence of proteinuria. Gross proteinuria (3+) was found in 0.4%. For the musculoskeletal system, history of fracture and plaster was observed in 9.3% though there was no deformity. Bone deformity following fracture was found in 1.3%. Testing of blood group revealed that the most common group was B+ve (33.4%), followed by O+ve (27.0%) and A+ve (24.3%).   2026 Ibrahim Medical College. All rights reserved.
