A pre-tested structured question-naire was used to elicit the required information from the study participants and the diagnostic criteria for hypertension were taken according to the Seventh Joint National Committee Report on Hypertension(JNC-7). Receiver operating characteristic(ROC) analysis was used to estimate the cut-off values of BMI and waist circumference to predict hypertension.RESULTS: The ROC analysis revealed that BMI is a good predictor of hypertension for both men(area under the ROC curve 0.714) and women(area under the ROC curve 0.821). The cut-off values of BMI for predicting hypertension were identified as ≥ 24.5 kg/m2 in men and ≥ 24.9 kg/m2 in women. Similarly, the ROC analysis for waist circumference showed that it is a good predictor of hypertension both for men(area under the ROC curve 0.784) and women(area under the ROC curve 0.815). The cut-offs for waist circumference for predicting hypertension were estimated as ≥ 83 cm for men and ≥ 78 cm for women. Adults with high BMI or high waist circumference had a higher prevalence of hypertension, respectively.CONCLUSION: Simple anthropometric measurements such as BMI and waist circumference can be used for screening people at increased risk of hypertension in order to refer them for more careful and early diagnostic evaluation. Policies and programs are required for primary and secondary prevention of hypertension.展开更多

Post-procedure markers of obesity and cardiometabolic profile were monitored regularly for a year.RESULTS Mean body mass index decreased by 29.5% from 41.9 to 29.5 kg/m^2 between baseline and 12-mo follow-up, while mean fat mass decreased by 45.9% from 64.2 kg to 34.7 kg. An improvement was also observed in the glucometabolic profile with both fasting glucose and HbA 1csubstantially decreasing(P < 0.001).CONCLUSION The present study shows the short to medium term(1 year) health benefits of bariatric surgery for patients of Middle Eastern ethnicity.展开更多

This has implications on decreased school performances, lower intelligent quotient levels, poor psychosocial development, and decreased cognitive functions. This study assessed the growth and body fat distribution among pupils aged 5 - 19 years. A cross-sectional study was conducted among pupils from five primary schools in different communities around Kainji Dam. This assessment was based on a comparison with reference standards set by the World Health Organization to determine their deviations. A qualified registered nurse carried out physical measurements to obtain age, height, and body weight using electronic weighing scale and stadiometer. Data were analyzed using Anthroplusv1.0.4 software. The overall prevalence of stunting was 21.5% with 8% being severely stunted. The prevalence of thinness was 35.2% with 11.2% being wasted while the overall prevalence of underweight was not calculated for children > 10 years old. The prevalence of underweight for 5 - 10 years old children was 16.9% with 2.4% being severely underweight. The curves for both male and female children deviated from normal distribution. Females have higher percentage of stunting than males. This study revealed a high prevalence of thinness and stunting which is the consequence of poor nutrition arising from multifaceted and interrelated circumstances such as poor feeding, eating practices and repeated infection. Intervention such as Home Grown School Feeding Programme of the Government is a right step in improving the nutritional status of pupils in rural communities.展开更多
