“…Our result showed adolescent with an increase of one BMI kg/m 2 was 1.12 times at risk of developing hypertension, that is, increase in one BMI kg/m 2 contributed by 12% of developing blood pressure among adolescents. Similar to our study, other studies have shown a positive association between adolescent hypertension and increasing BMI 10 14 24 28 29.

ObjectivesThere is an increasing rate of elevated blood pressure, or hypertension, in children and adolescents worldwide, including Sub-Saharan Africa (SSA). Only a few data on adolescent hypertension in SSA, including Sudan, have been published. The aim of the present study was to investigate the prevalence and associated factors of hypertension among adolescent schoolchildren (within the ages of 10 to 19 years) in Sudan.DesignA cross-sectional school-based study was conducted from June to September 2022.SettingsSix randomly selected schools in Almatamah, River Nile State, Sudan.ParticipantsAdolescent schoolchildren (within the ages of 10 to 19 years).Main outcome measuresSociodemographic information. Anthropometric and blood pressure measurements were performed in accordance with the standard procedures. An adjusted logistic regression analysis was performed.ResultsOf the 384 enrolled adolescents, 166 (43.2%) and 218 (56.8%) were boys and girls, respectively. The median (IQR) age and body mass index (BMI) were 15.2 years (14.0‒16.4 years) and 18.5 kg/m2(16.4‒21.5 kg/m2), respectively. Of the 384 adolescents, 240 (62.5%) and 255 (66.4%) had educated mothers and fathers (≥secondary), respectively. 38 adolescents (9.9%) had hypertension (≥95th percentile). The multivariable logistic regression analysis revealed that age, sex and maternal educational level were not associated with hypertension. Paternal educational level according to secondary education attainment (adjusted OR (AOR), 2.72; 95% CI 1.36‒5.46) and increasing BMI (AOR, 1.12; 95% CI 1.02‒1.20) were associated with hypertension.Conclusion1 in 10 adolescents in northern Sudan was hypertensive. Low paternal educational level and increasing BMI were significantly associated with hypertension. The introduction of interventional nutritional programmes at early ages is needed to ensure that adolescents are healthy in their present and later lives. To sustain such programmes, involving all educational parties at early stage is essential.

“…BMI was calculated according to the formula of dividing participants’ weight in kilograms (kg) by their height in metres (m) squared 23. To have an accurate estimation of the influence of one unit increase in BMI on blood pressure among adolescents, in this study, BMI was analysed as a continuous variable, similar to recent studies 14 24…”

“…Of the 53 studies, 37 reported obesity and/or overweight prevalence in their respective samples [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] , [55] , [56] , [57] , [58] , [59] , [60] , [61] , [62] , [63] , [64] , [65] , [66] , [67] , [68] , [69] , [70] , with the prevalence of obesity ranging from 0·3% to 50% These studies consistently found a higher prevalence of elevated BP and/or hypertension in participants with obesity, overweight, or central obesity. A case-control study where authors compared prevalence of hypertension in children with and with out obesity found that only the children in the obesity group had hypertension (25%), and this group had significantly more cases of elevated BP than the non-obesity group (19·4% vs 6·5%) (Chedjou-Nono et al [68] ).…”

Paediatric Hypertension in Africa: A Systematic Review and Meta-Analysis

et al. 2022

Background The burden of cardiovascular disease (CVD) and hypertension is rapidly increasing in low- and middle-income countries. This is evident not only in adults, but also in children. Recent estimates of prevalence in children are lacking, particularly in Africa. As such, we conducted a systematic review and meta-analysis to provide updated estimates of paediatric hypertension in Africa. Methods We searched PubMed and EBSCO to identify articles published from January 2017 to November 2020. Studies were assessed for quality. We combined results for meta-analyses using a random effects model (Freeman-Tukey arcsine transformation). Heterogeneity was quantified using the I 2 statistic. Findings In the narrative synthesis of 53 studies, publication bias was low for 28, moderate for 24, and high for one study. Hypertension prevalence ranged substantially (0·2%-38·9%). Meta-analysis included 41 studies resulting in data on 52918 participants aged 3 to 19 years from ten countries. The pooled prevalence for hypertension (systolic/diastolic BP≥95th percentile) was 7·45% (95%CI 5·30-9·92, I 2 =98.96%), elevated blood pressure (BP, systolic/diastolic BP≥90th percentile and <95th percentile) 11·38% (95%CI 7·94-15·33, I 2 =98.97%) and combined hypertension/elevated BP 21·74% (95%CI 15·5-28·69, I 2 =99.48%). Participants categorized as overweight/with obesity had a higher prevalence of hypertension (18·5% [95%CI 10·2-28·5]) than those categorized as underweight/normal (1·0% [95%CI 0·1-2·6], 4·8% [95%CI 2·9-7·1], p<0·001). There were significant differences in hypertension prevalence when comparing BP measurement methods and classification guidelines. Interpretation Compared to a previous systematic review conducted in 2017, this study suggests a continued increase in prevalence of paediatric hypertension in Africa, and highlights the potential role of increasing overweight/obesity.

“…The WHR had no correlation with SBP in boys and only in females from public schools did it manifest a fair and significant correlation. Such inconsistencies involving WHR correlation with SBP have been described in other studies although involving private school children from outside Africa (25), only. While all three of BMI, WC and WHtR appear applicable in predicting how high SBP in such a cohort as the current might be regardless of what type of school participants attend, it looks feasible to say that WHR would only be applicable in females attending public schools, weakening its applicability over the rest.…”

Kenyan studies relating body composition (BC) and blood pressure (BP) have focused on adults. Insight into this relationship among children and adolescents provides evidence for reduction of adulthood cardiovascular disease-risk development. We describe BC and BP correlation among Kenyan children and adolescents. This cross-sectional study randomly sampled 389 school-going participants. Weight, height, BP, waist circumference (WC) and hip circumference were measured. Waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and body-mass-index (BMI) were calculated. Relationships between BP and WC, WHR, WHtR and BMI were determined. Males and females were 14.7±2.9 and 14.4±2.5 years old, respectively. Secondary and primary schools’ males had SBP 119.1±10.3 mmHg and 107.4±13.7 mmHg; females 111.2±11.8 mmHg and 106.7±11.7 mmHg respectively. The DBP in secondary and primary schools’ males was 69.2±7.8 mmHg and 65.7±8.6mmHg, and, 69.6±7.9 mmHg and 68.1±7.4 mmHg for females. Higher BMI, WC, and WHtR correlated with higher SBP in both sexes (Pearson’s “R” +0.3 to +0.5; p<0.05). In females, DBP correlated with BMI, WC and WHtR, and only with WC for males. In all schools, only WC correlated with SBP in both sexes, BMI, WHR and WHtR correlating only among females. For males, BMI in primary and WHtR and WHR in secondary schools additionally correlated with SBP. For females, BMI and WHtR had correlations across school levels. For private and public schools, BMI, WC and WHtR had +0.2 to +0.6 correlations with SBP. The DBP correlated with WC and WHtR among private schools’ males, and, with WHtR and BMI in both school sets for females. For both sexes, WC had strongest and WHR weakest correlation with SBP. Only in secondary school females did DBP correlate some BC variables. In both sexes, BMI, WC and WHtR all fairly correlated with SBP in private and public schools, WHR appearing least applicable in predicting Kenyan children and adolescents’ BP.
