Association Between Abdominal Waist Circumference and Blood Pressure In Brazilian Adolescents With Normal Body Mass Index: Waist circumference and blood pressure in Adolescents

Hypertension care cascade and their determinants among older adolescents in India: evidence from a nationally representative cross-sectional survey

Adolescent hypertension in India is an emergent public health concern with lack of programmatic focus on regular screening amongst both individuals and healthcare providers. This study was conducted to assess the hypertension care cascade (prevalence, awareness, treatment and control status of hypertension) from nationally representative data. We used data from the demographic and health surveillance (DHS) comprising India's National Family Health Survey Fifth Round (2019-2021). The prevalence of hypertension among 204,054 older adolescents (15-19 years) was 5.08% (95% CI: 4.94-5.23%) wherein 42.26% (95% CI: 40.69-43.64%) were aware of their condition, 43.70% (95% CI: 41.73-45.70%) of those aware were receiving treatment, and 85.88% (95% CI: 83.83-87.71%) of those on treatment achieved blood pressure control. Overall, there were nearly 60% newly diagnosed hypertension cases detected on screening. Females had significantly lower odds, while those with diabetes and higher waist-hip ratio had significantly higher odds of having hypertension. The awareness of their hypertensive status was higher among females and rural residents, while it was lower among adolescents that were obese and tobacco smokers. Improved blood pressure control was associated with a lower waist-to-hip ratio. In conclusion, nearly five in every hundred older adolescents in India are clinically hypertensive with significantly higher odds linked with obesity and male gender. Awareness and utilization of antihypertensive treatment was lower than the classical rule of halves signifying deficiencies in hypertension screening and management strategies for older adolescents within the existing public health policy framework.

Fever as a Predictor of COVID-19 Outcomes in Hospitalized Patients

INTRODUCTION

With the advent of the COVID-19 pandemic, numerous questions have arisen regarding the screening, diagnosis, treatment, and prognosis of infected patients. Among these, screening infected patients through body temperature measurement has proven ineffective. However, doubts persist regarding the role of fever as a prognostic factor in the disease.

OBJECTIVE

To assess the prevalence of fever and its relevance as a marker of mortality in COVID-19.

METHODOLOGY

This prospective and longitudinal cohort study was conducted between April 2020 and December 2021 and analyzed 1400 COVID-19 patients systematically admitted to the emergency department of a reference hospital during the period from April 2020 to December 2021, in the city of Curitiba, Brazil. [LG1] The study evaluated [LG2] the presence of fever (body temperature above 37,7ºC) upon admission and/or during hospitalization, patient profiles, and outcomes (in-hospital death, discharge, admission at the intensive care unit, need of mechanical ventilation).

RESULTS

Fever was present in 128 participants (9.1%), with a higher prevalence in males (71%) and obese individuals (42.9%). Among the febrile patients, 39 required intubation (30.4%), with two intubated upon admission (1.5%), 104 were discharged (81.2%), and 24 deceased (18.7%). Fever was not associated with a higher mortality rate.

CONCLUSION

Fever showed low prevalence, is more common in males and obese individuals, and is not related to worse clinical outcomes.

Hypertension effects of the COVID-19 lockdowns: Evidence from a repeated cross-sectional survey in Peru

Using data from Peru and a quasi-experimental approach, we document significant increases in arterial blood pressure and in the incidence of arterial hypertension caused by the restrictive measures employed by the Peruvian authorities during the COVID-19 pandemic. The effects are more pronounced for women, older respondents, and urban residents. The effects are statistically significant and high in magnitude relative to the pre-pandemic incidence of disease in the Peruvian population. A main channel of disease propagation seems to be the changes in dietary habits and physical activity imposed by the COVID-19 lockdowns, which affected several anthropometric measurements that are common risk factors for hypertension.

Relationship between measures of adiposity and hypertension amongst secondary school adolescents in an urban setting in Cameroon

Introduction

measures of obesity such as body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) have been shown to be associated with high blood pressure (BP) in children and adolescents. The purpose of this study was to determine the proportion of secondary school adolescents with elevated BP and high BP in relation to some measures of adiposity (BMI, WC, WHtR) and to examine the association between BP and adiposity indices amongst the children.

Methods

the study was an institutional-based cross-sectional study involving 534 adolescents (mean age 15.1 ± 2.3 years) attending 4 secondary schools (2 public and 2 private) in the Bamenda municipality of the North West Region of Cameroon. Anthropometric and BP measurements were carried out following standard procedures. Diagnosis of hypertension in the children was done by obtaining three elevated systolic or diastolic BP readings (BP ≥ 95th percentile for the child's age, sex and height). Linear regression was used to determine the relationship between BP and some measures of adiposity (BMI, WC, WHtR) amongst the children.

Results

the prevalence of elevated BP and hypertension amongst the study participants was 33.3% and 33.3% in the BMI-obese children, 25.9% and 25.2% in the WC overweight/obese children and 29.4% and 41.2% in the "high risk" (WHtR ≥ 0.5) children respectively. Body mass index-obese, WC overweight/obese and "high risk" (WHtR ≥ 0.5) children had a significantly (p <0.05) higher mean SBP and DBP compared to their healthy weight counterparts. Linear regression indicated a significant association (p <0.001) between WC (β=0.75; 95% CI = 0.57, 0.92), BMI (β=0.88; 95% CI = 0.49, 1.25) and WHtR (β= 67.08; 95% CI = 45.64, 88.51) with systolic BP for the unadjusted analysis. After adjusting for age, gender and school type, only WC (β= 0.66; 95% CI = (0.43, 0.89) showed a positive significant (p <0.001) relationship with systolic BP.

Conclusion

this study has demonstrated that WC is positively associated with high BP in children and adolescents. Thus, WC can be used in predicting children and adolescents with a high risk of developing high BP in our setting.

Evaluation of the relationship between nutritional status, levels of physical activity and physical strength in adolescents

BACKGROUND & AIMS

The study aimed at evaluating the relationship among anthropometric measurements, levels of physical activity and physical fitness in schoolchildren.

METHODS

A cross-sectional study was carried out in public schools, with 173 adolescents from 10 to 17 years of age. Socioeconomic data were obtained by a structured questionnaire. Anthropometric measures were assessed and classified according to Body Mass Index (BMI)/age and Waist Circumference (WC). The long version of the International Physical Activity Questionnaire (IPAQ) was used to assess the level of physical activity, while the physical fitness level was assessed using the Projeto Esporte Brasil (PROESP) test protocol.

RESULTS

72,3% of the adolescents were eutrophic and 24.3% were overweight and 22.6% were at high risk for cardiovascular disease, with no statistical difference between the sexes (p > 0.05). 53.8% were physically inactive, regardless of sex and nutritional status. 86.1% of the adolescents showed low physical fitness, more significantly for sit-and-reach andsquare tests of females. BMI was directly correlated with physical fitness in the assessment ofupper limb power and agility (medicine ball throw and square test) and indirectly with aerobic capacity and lower limb power (abdominal resistance, horizontal jump and general resistance). The opposite was observed in the correlation of endurance (abdominal and general) and medicine ball throw with WC. Also, there was a likely visceral obesity and consequent cardiovascular risk in females more than in males.

CONCLUSIONS

These findings reinforce the connection between physical activity and the presence of overweight and obesity in adolescents and also the need to effectively intervene in this groupin order to ensure the prevention of chronic non-communicable diseases in adulthood.

Comparison of Glycosylated Haemoglobin, Blood Pressure, and Anthropometric Measurements Depending on Gender and Bodyweight State in Adolescents

Background/Objective: The greatest anthropometric and physiological changes occur during adolescence. Assessment of growth patterns is necessary to prevent future health risks. Aims: To describe the values of glycosylated haemoglobin (HbA1c), systolic (SBP) and diastolic (DBP) blood pressure, triceps skinfold, and abdominal circumference according to gender and age (between 12 and 17 years), as well as explore the differences between body weight conditions. Methods: A descriptive cross-sectional study was carried out, including 4130 adolescents between 12 and 17 years old. SBP and DBP, HbA1c, triceps skinfold, and abdominal circumference were evaluated. Results: Significant differences were observed between males and females for HbA1c (p < 0.001), SBP (p < 0.001), triceps curl (p < 0.001), and abdominal circumference (p < 0.001), independently of the age group. Regardless of gender and age groups, significant differences were observed between overweight/obese and normal-weight adolescents in SBP (p < 0.001), DBP (p < 0.001 to 0.009), triceps skinfold (p < 0.001), and abdominal perimeter (p < 0.001). Conclusions: Our findings revealed higher SBP, DBP, triceps skinfold, and abdominal circumference in overweight/obese adolescents compared to normal-weight adolescents in both genders.

Effect of changes in body mass index and waist-to-height ratio on blood pressure in 11- to 13-year-old children: a prospective population study

BACKGROUND

Existing evidence about associations between change in body mass index (BMI) and waist-to-height ratio (WHtR) change and high blood pressure are relatively limited.

AIMS

We aimed to investigate the associations of general overweight (based on BMI) and abdominal obesity (based on WHtR) change with high blood pressure in Chinese children.

SUBJECTS AND METHODS

A school-based cohort study in Ningbo region (China) was conducted among children with baseline evaluations in October 2016 with follow-up two years later. A total of 1432 children aged 11-13 years participated in this study.

RESULTS

Our results showed that a change from normal BMI or WHtR to overweight or abdominal obesity in children was associated with high blood pressure (adjusted odds ratio (AOR), 2.62; p<0.05 or AOR, 2.79; p<0.05, respectively). In addition, an increased risk of high blood pressure was observed in children who maintained overweight or abdominal obesity (AOR, 1.67; p<0.05 or AOR, 1.69; p<0.05, respectively), but not in children who experienced remission to non-excess weight. Interestingly, children who increased BMI or WHtR had greater impact on SBP than on DBP.

CONCLUSION

The 2-year longitudinal study indicated that general overweight or abdominal obesity can predict the risk factor of high blood pressure in children. However, children who remitted to non-excess weight did not exhibit an increased risk of high blood pressure.

[Temporal variation in the incidence of overweight and abdominal obesity among adolescents in the city of Salvador, Bahia, Brazil]

The scope of this study was to analyze the temporal variation in the incidence of overweight and abdominal obesity among adolescents from public schools in a capital in northeastern Brazil. It is a study including information from three cross-sectional surveys carried out in 2001, 2009 and 2017, with 2,496 students aged 10 to 18 years of both sexes living in the city of Salvador, Bahia. Overweight was assessed using the Body Mass Index for Age (BMI/A) and abdominal obesity was assessed using waist circumference and waist-to-height ratio. Pooled OLS (Ordinary Least Squares) regression, with constant effect, was used to assess the variation of anthropometric indicators over the period. The results of this study indicate that the prevalence of overweight increased by 103% and the indicators of abdominal obesity increased by 153% and 142%, respectively, in the period under analysis. The increase in the mean body mass index and waist-to-height ratio was greater among adolescents and in the mean BMI and waist circumference among those aged 14 to 18 years old. The conclusion reached was that there was a significant increase in the prevalence of overweight and abdominal obesity in the period 2001 to 2017 among adolescents in the city of Salvador.

Identification of Adolescents with Adiposities and Elevated Blood Pressure and Implementation of Preventive Measures Warrants the Use of Multiple Clinical Assessment Tools

The burden of abdominal adiposity has increased globally, which is recognized as a key condition for the development of obesity-related disorders among youth, including type 2 diabetes, cardiovascular disease, and hypertension. High blood pressure (BP) and cardiovascular diseases increase the rates of premature mortality and morbidity substantially. Aims: to investigate the relation between abdominal adiposity and elevated BP among adolescent males in Jordan. Methods: Nationally representative sample of male adolescents was selected using multi-cluster sampling technique. Study sample included 1035 adolescent males aged 12 to 17 years. Multiple indicators were used to assess adiposity including waist circumference (WC) and total body fat (TF), truncal fat (TrF), and visceral fat (VF). Systolic blood pressure was measured to assess hypertension. Results: After adjusting for age, smoking status, and physical activity, the odds of having stage two hypertension increased 6, 7, and 8 times for adolescents who were on 90th percentile or above for Trf, VF, and WC, respectively. Conclusion: Elevated BP was significantly associated with total and abdominal adiposity among adolescent males in Jordan. Use of multiple clinical assessment tools is essential to assess abdominal obesity among adolescents.
